M's surroundings. The target orbit contains, for example, a velocity element. For example, the target track is expressed as a track in which points (track points) to be reached by the host vehicle M are arranged in order. The track point is a point that the host vehicle M should arrive at every predetermined travel distance (for example, about several [m]) in terms of the distance along the route, and on the other hand, every predetermined sampling time (for example, several tenths [sec]) ] level) target velocity and target acceleration are generated as part of the target trajectory. In addition, the track point may be a position to be reached by the host vehicle M at the sampling time every predetermined sampling time.

[交叉路口通过控制][Intersection Pass Control]

以下,对行动计划生成部140的各部分进行说明。行动计划生成部140例如具备交叉路口通过控制部142。交叉路口通过控制部142例如具备追随行驶控制部144和凭自己通过控制部156。追随行驶控制部144例如具备追随对象确定部146、转弯形态预测部148及转弯一致判定部150。Hereinafter, each part of the actionplan generation unit 140 will be described. The actionplan generation unit 140 includes, for example, an intersection passingcontrol unit 142 . The intersection passingcontrol unit 142 includes, for example, a followingtravel control unit 144 and a self-passingcontrol unit 156 . The followingtravel control unit 144 includes, for example, a followingtarget identification unit 146 , a turningshape predicting unit 148 , and a turningcoincidence determination unit 150 .

交叉路口通过控制部142在交叉路口通过事件起动了时进行动作。交叉路口通过控制部142在通过交叉路口时,在追随前行车辆而通过交叉路口的追随行驶模式与凭自己识别行进前方而通过交叉路口的凭自己通过模式之间进行切换来进行控制。The intersection passingcontrol unit 142 operates when an intersection passing event is activated. When passing through the intersection, the intersection passingcontrol unit 142 performs control by switching between the following travel mode in which the vehicle follows the preceding vehicle and passes through the intersection, and the self-passing mode in which the vehicle passes through the intersection by recognizing the front of the vehicle.

追随行驶控制部144在交叉路口通过控制部142选择了追随行驶模式的情况下进行动作。图3是用于对追随行驶控制部144的功能进行说明的图(其1)。本车辆M按照用于去往前述的目的地的推荐路径,想要在交叉路口CR右转而向(A)方面行进。右转是左侧通行的地域或国家中的“跨过相向车辆的前进道路地通过交叉路口”的动作的一例。与此相反,左转是右侧通行的地域或国家中的“跨过相向车辆的前进道路地通过交叉路口”的动作的一例。在图3所示的场景中,例如,在由于前行车辆m1使右转向灯工作而由前行车辆监视部132推定出右转的意图的情况下,追随行驶控制部144决定为追随该前行车辆m1而通过交叉路口。追随行驶控制部144以相对于前行车辆m1一边维持规定的车间距离、一边使横向位置一致的方式生成目标轨道。即,追随行驶控制部144通过进行与前行车辆m1的行为相应的行驶控制,来使本车辆M追随前行车辆m1而行驶。The followingtravel control unit 144 operates when the following travel mode is selected by thecontrol unit 142 at the intersection. FIG. 3 is a diagram (No. 1 ) for explaining the function of the followingtravel control unit 144 . The host vehicle M intends to turn right at the intersection CR and proceed in the direction (A) according to the recommended route for the destination. A right turn is an example of an action of "passing the intersection over the path of the oncoming vehicle" in a region or country where the vehicle is traveling on the left. On the other hand, the left turn is an example of the action of "passing the intersection over the path of the oncoming vehicle" in a region or country where the vehicle is traveling on the right. In the scenario shown in FIG. 3 , for example, when the precedingvehicle monitoring unit 132 estimates an intention to turn right because the preceding vehicle m1 activates the right turn signal, the followingtravel control unit 144 determines to follow the preceding vehicle m1. The vehicle m1 passes through the intersection. The followingtravel control unit 144 generates a target trajectory so as to align the lateral positions with respect to the preceding vehicle m1 while maintaining a predetermined inter-vehicle distance. That is, the followingtravel control unit 144 causes the host vehicle M to travel following the preceding vehicle m1 by performing travel control according to the behavior of the preceding vehicle m1.

然而,并非前行车辆一定会去往本车辆M的目的地。图4是用于对追随行驶控制部144的功能进行说明的图(其2)。在图示的场景中,前行车辆m2不是要在交叉路口CR右转,而是要进入位于交叉路口CR的附近的道路外区域HA。当在这样的场景下追随前行车辆m2而行驶时,本车辆M也会进入道路外区域HA。因此,追随行驶控制部144停止使本车辆M追随前行车辆m2而行驶,将控制委托给凭自己通过控制部156。另外,由于存在这样的情由,所以在图3及图4所示的场景中,例如优选空出某种程度的间隔地追随前行车辆。而且,自动驾驶控制装置100通过以下说明的功能,进行在特定的右转点提高追随的确信度的控制。由此,能够更适当地实现右转时的追随行驶。However, the preceding vehicle does not necessarily go to the destination of the host vehicle M. FIG. 4 is a diagram (No. 2 ) for explaining the function of the followingtravel control unit 144 . In the illustrated scene, the preceding vehicle m2 is not about to turn right at the intersection CR, but is about to enter the off-road area HA located in the vicinity of the intersection CR. When traveling following the preceding vehicle m2 in such a scenario, the host vehicle M also enters the off-road area HA. Therefore, the followingtravel control unit 144 stops causing the host vehicle M to travel following the preceding vehicle m2 , and entrusts the control to the self-passingcontrol unit 156 . In addition, for such reasons, in the scenarios shown in FIGS. 3 and 4 , for example, it is preferable to follow the preceding vehicle with a certain interval. Then, the automaticdriving control device 100 performs control to increase the certainty of following at a specific right-turn point by the function described below. This makes it possible to more appropriately realize the following travel when turning right.

以下,对本车辆M进行右转的情况下的各功能部的功能依次进行说明。前行车辆监视部132推定前行车辆右转的意图。前行车辆监视部132是“推定部”的一例。例如,前行车辆监视部132基于前行车辆的行驶行车道、转向灯的工作状态,来推定前行车辆右转的意图。前行车辆监视部132例如基于第二地图信息62所包含的各行驶行车道的类别(右转行车道、左转行车道等)及前行车辆的位置、从相机10的拍摄图像得到的在道路上描绘的道路标示的内容和/或处于道路侧的道路标识的内容、或者从相机10的拍摄图像得到的转向灯的工作状态等,来进行上述的意图推定。Hereinafter, the functions of each functional unit when the host vehicle M makes a right turn will be described in order. The precedingvehicle monitoring unit 132 estimates the intention of the preceding vehicle to turn right. The precedingvehicle monitoring unit 132 is an example of an "estimation unit". For example, the precedingvehicle monitoring unit 132 estimates the intention of the preceding vehicle to turn right based on the driving lane of the preceding vehicle and the operating state of the turn signal. The precedingvehicle monitoring unit 132 , for example, based on the type (right-turning lane, left-turning lane, etc.) of each driving lane included in thesecond map information 62 and the position of the preceding vehicle, and the location obtained from the captured image of thecamera 10 . The above-described intent estimation is performed based on the content of road signs drawn on the road and/or the content of road signs on the road side, or the operation state of the turn signal obtained from the captured image of thecamera 10 .

而且,前行车辆监视部132识别在本车辆M的前方行驶的前行车辆的转弯的有无、转弯开始地点、转弯角度等。前行车辆监视部132例如基于相机10的拍摄图像中的车身的轮廓的倾斜、车轮的角度、由雷达装置12、探测器14检测出的物体目标点的分布等,来识别与上述的转弯相关的状况。Furthermore, the precedingvehicle monitoring unit 132 recognizes the presence or absence of a turn of the preceding vehicle traveling in front of the host vehicle M, the turning start point, the turning angle, and the like. The precedingvehicle monitoring unit 132 recognizes, for example, the inclination of the contour of the vehicle body, the angle of the wheels, the distribution of object target points detected by theradar device 12 and thedetector 14, and the like in the image captured by thecamera 10, and identifies the relation related to the above-mentioned turning. condition.

追随对象确定部146确定追随对象的前行车辆。例如在满足了(A)在与本车辆M之间不存在其他车辆的状态下正在本车辆M的前方行驶这一条件和(B)由前行车辆监视部132推定出前行车辆的右转的意图这一条件的双方的情况下,追随对象确定部146将该前行车辆确定为右转时的追随对象的前行车辆。需要说明的是,追随对象确定部146也可以在本车辆M的直行时、左转时,基于与上述(A)、(B)不同的条件来确定追随对象的前行车辆。The followingtarget identification unit 146 identifies a preceding vehicle to be followed. For example, when (A) the condition that the vehicle M is traveling in front of the vehicle M in a state where no other vehicle exists between the vehicle M and the vehicle M and (B) the right turn of the preceding vehicle is estimated by the precedingvehicle monitoring unit 132 are satisfied When both of these conditions are intended, the followingtarget identification unit 146 identifies the preceding vehicle as the preceding vehicle to be followed when turning right. It should be noted that the followingtarget specifying unit 146 may specify a preceding vehicle to be followed based on conditions different from those of (A) and (B) described above when the host vehicle M is going straight or turning left.

另外,在由识别部130识别出在本车辆M行驶的道路上、更具体而言在进行右转的交叉路口的跟前侧存在从本车辆M的附近无中断地延伸到交叉路口为止的中央隔离带的情况下,追随对象确定部146提高向前行车辆追随的确信度。更具体而言,在进行右转的交叉路口的跟前侧且本车辆M行驶的道路的隔着相向车道相望的对面侧存在道路外区域HA的情况下,在去往道路外区域HA的跨过相向车道的进入路径上存在中央隔离带时,追随对象确定部146提高向前行车辆的追随的确信度。需要说明的是,也可以是,在不存在这样的道路外区域HA的情况下,即使不存在中央隔离带也提高向前行车辆追随的确信度。这是因为,在这些情况下,能够排除前行车辆进入道路外区域HA的可能性。需要说明的是,识别部130可以基于相机10等的输出来识别中央隔离带的存在,也可以通过将第二地图信息62与本车辆M的位置进行比较来识别中央隔离带的存在。In addition, on the road on which the vehicle M is recognized by therecognition unit 130, more specifically, on the immediate side of the intersection where the vehicle M is making a right turn, there is a central separation extending from the vicinity of the vehicle M to the intersection without interruption. In the case of a belt, the followingtarget specifying unit 146 increases the certainty of following the preceding vehicle. More specifically, when the off-road area HA exists on the opposite side of the road on which the host vehicle M travels across the opposite lane on the immediate side of the intersection where the right turn is made, the off-road area HA is crossed to the off-road area HA. When the median barrier exists on the entry path passing through the opposite lane, the followingtarget specifying unit 146 increases the certainty of following the preceding vehicle. In addition, in the case where such an off-road area HA does not exist, even if a median does not exist, the certainty degree of following a preceding vehicle may be improved. This is because, in these cases, the possibility that the preceding vehicle enters the off-road area HA can be excluded. It should be noted that theidentification unit 130 may identify the presence of the median based on the output of thecamera 10 or the like, or may identify the presence of the median by comparing thesecond map information 62 with the position of the vehicle M.

图5是用于对追随行驶控制部144的功能进行说明的图(其3)。在图示的场景中,前行车辆m3正在作为右转专用行车道的车道L2上行驶,所以推定出右转的意图。另外,在交叉路口CR的跟前延伸有中央隔离带CD。因此,追随对象确定部146提高向前行车辆m3追随的确信度。FIG. 5 is a diagram (No. 3 ) for explaining the function of the followingtravel control unit 144 . In the illustrated scene, the preceding vehicle m3 is traveling on the lane L2 which is a right-turn dedicated traffic lane, so the intention to turn right is estimated. In addition, a median CD extends in front of the intersection CR. Therefore, the followingtarget specifying unit 146 increases the certainty of following the preceding vehicle m3.

追随行驶控制部144使本车辆M追随至少由追随对象确定部146认定为追随的确信度高的前行车辆m3而通过交叉路口CR。所谓的“使其追随而通过交叉路口CR”包含开始追随和继续追随中的一方或双方。追随行驶控制部144对于由追随对象确定部146认定为追随的确信度高的前行车辆m3,例如执行如下(1)、(2)及(3)等控制中的至少一个,其中,(1)与追随的确信度不高的情况(例如图3所示的前行车辆m1的情况)相比,将追随开始的时机提前;(2)与追随的确信度不高的情况相比,缩短与追随的前行车辆m3之间的车间距离;(3)至少到达中央隔离带CD的端部CD1的附近为止继续追随。The followingtravel control unit 144 causes the host vehicle M to follow at least the preceding vehicle m3 that has a high degree of certainty of following by the followingtarget specifying unit 146 to pass through the intersection CR. The so-called "make it follow and pass the intersection CR" includes one or both of starting following and continuing to follow. The followingtravel control unit 144 executes, for example, at least one of the following controls (1), (2), and (3) with respect to the preceding vehicle m3 that is determined by the followingtarget determination unit 146 to be followed with a high degree of certainty, wherein (1) ) compared with the case where the certainty of following is not high (for example, in the case of the preceding vehicle m1 shown in FIG. 3 ), the timing of starting the following is advanced; (2) compared with the case where the certainty of the following is not high, shorten the time The vehicle-to-vehicle distance to the following preceding vehicle m3; (3) Continue to follow until it reaches at least the vicinity of the end CD1 of the center median CD.

转弯形态预测部148预测追随对象的前行车辆用于在交叉路口CR向预定的方向通过的预想路径中的转弯开始地点。转弯形态预测部148例如进行第二地图信息62与本车辆M的当前位置之间的匹配,在基于第二地图信息62的道路形状模型上生成预想路径。然后,转弯形态预测部148预测预想路径中的转弯开始地点和转弯角度。The turningshape predicting unit 148 predicts a turning start point on an expected route for the preceding vehicle to follow in a predetermined direction to pass through the intersection CR. The turningform predicting unit 148 performs, for example, matching between thesecond map information 62 and the current position of the host vehicle M, and generates an estimated route on the road shape model based on thesecond map information 62 . Then, the turningform predicting unit 148 predicts the turning start point and turning angle on the expected route.

图6是用于对由转弯形态预测部148生成的预想路径进行说明的图。在图中,PR是预想路径,SP是转弯开始地点,θ是转弯角。转弯形态预测部148例如假想地设定车道L2和车道L3各自的中央线,将利用与中央线的双方内切的圆弧对中央线进行连接而成的路径设为预想路径。虽然与中央线的双方内切的圆弧能够设定多组,但转弯形态预测部148例如在从车道L2与交叉路口CR的交界起开始转弯的前提下生成预想路径。车道L2与交叉路口CR的交界基于中央隔离带CD的端部CD1的位置、道路划分线的中断、停止线(未图示)、道路的角部CN的位置等而设定。并且,转弯形态预测部148将车道L2的中央线与圆弧的连接部位预测为转弯开始地点SP,将车道L2的中央线与车道L3的中央线所呈的角度预测为转弯角度θ。需要说明的是,在参照第二地图信息62而知晓了为一般形状的十字路的情况下,也可以省略预想路径的生成而设定为转弯角度θ=90度。FIG. 6 is a diagram for explaining the expected route generated by the turningform predicting unit 148 . In the figure, PR is the expected route, SP is the turning start point, and θ is the turning angle. For example, the turningform predicting unit 148 sets the center line of each of the lane L2 and the lane L3 imaginatively, and uses a route in which the center line is connected by arcs inscribed on both sides of the center line as an expected route. Although a plurality of sets of arcs inscribed on both sides of the center line can be set, the turningform predicting unit 148 generates an expected route on the premise that the turning starts from the boundary between the lane L2 and the intersection CR, for example. The boundary between the lane L2 and the intersection CR is set based on the position of the edge CD1 of the median CD, the interruption of the road dividing line, the stop line (not shown), the position of the corner CN of the road, and the like. Then, the turningform predicting unit 148 predicts the connection between the center line of the lane L2 and the arc as the turning start point SP, and predicts the angle formed by the center line of the lane L2 and the center line of the lane L3 as the turning angle θ. It should be noted that when a crossroad with a general shape is known with reference to thesecond map information 62 , the generation of the predicted route may be omitted and the turning angle θ=90 degrees may be set.

另外,在交叉路口CR内设定有右转待转行车道(设置于交叉路口内的专用行车道的一例)的情况下,转弯形态预测部148也可以以右转待转行车道的位置为基准而求出预想路径。图7是用于对设定有右转待转行车道的情况下的转弯形态预测部148的处理进行说明的图。如图所示,有时在交叉路口CR内设定有(在道路上描绘有)由道路划分线DL划分的右转待转行车道RWL。右转待转行车道RWL的存在及位置通过识别部130识别道路划分线DL而识别。在存在右转待转行车道RWL的情况下,转弯形态预测部148以通过右转待转行车道RWL内且从右转待转行车道RWL的端部RWL1与车道L3的中央线相连的方式生成预想路径PR。In addition, when a right-turn pending lane (an example of a dedicated lane provided in the intersection) is set in the intersection CR, the turningshape predicting unit 148 may use the position of the right-turn pending lane as a reference. Find the expected path. FIG. 7 is a diagram for explaining the processing of the turningform predicting unit 148 when a right-turn waiting lane is set. As shown in the figure, a right-turn waiting lane RWL divided by a road dividing line DL may be set in the intersection CR (drawn on the road). The presence and position of the right-turn lane RWL are recognized by therecognition unit 130 by recognizing the road dividing line DL. When there is a right-turn pending lane RWL, the turningshape predicting unit 148 generates an expected route so as to pass through the right-turn pending lane RWL and connect from the end RWL1 of the right-turn pending lane RWL to the center line of the lane L3 PR.

转弯一致判定部150判定由前行车辆监视部132识别出的前行车辆的转弯开始地点是否与预想路径中的转弯开始地点SP一致。所谓一致,是指前行车辆的转弯开始地点与转弯开始地点SP之间的距离落入规定的距离范围内。The turncoincidence determination unit 150 determines whether or not the turn start point of the preceding vehicle recognized by the precedingvehicle monitoring unit 132 matches the turn start point SP on the expected route. Matching means that the distance between the turning start point of the preceding vehicle and the turning start point SP falls within a predetermined distance range.

另外,转弯一致判定部150判定由前行车辆监视部132识别出的前行车辆的转弯角度是否与预想路径中的转弯角度θ一致。所谓一致,是指前行车辆的转弯角度与转弯角度θ之差落入规定的角度范围内。In addition, the turn matchingdetermination unit 150 determines whether or not the turning angle of the preceding vehicle identified by the precedingvehicle monitoring unit 132 matches the turning angle θ on the expected route. The so-called coincidence means that the difference between the turning angle of the preceding vehicle and the turning angle θ falls within a predetermined angle range.

在规定的条件下(后述)由转弯一致判定部150判定为转弯开始地点和转弯角度中的至少一方与前行车辆的转弯形态不一致的情况下,追随行驶控制部144停止追随前行车辆而通过交叉路口。When at least one of the turning start point and the turning angle is determined by the turningcoincidence determination unit 150 to be inconsistent with the turning form of the preceding vehicle under predetermined conditions (described later), the followingtravel control unit 144 stops following the preceding vehicle and through the intersection.

在停止了向前行车辆的追随后或者原本不追随前行车辆而通过交叉路口的情况下,凭自己通过控制部156起动,生成用于通过交叉路口的目标轨道。凭自己通过控制部156例如通过与转弯形态预测部148生成预想路径同样的方法来生成本车辆M的目标轨道。另外,凭自己通过控制部156使用经由相机10等而取得的信息来进行地图背景的周边物体(信号机、停止线、道路标识等)的配置与实际的周边物体的配置之间的匹配,确保目标轨道的精度。When following the preceding vehicle is stopped or when passing through the intersection without originally following the preceding vehicle, the passingcontrol unit 156 is activated by itself to generate a target trajectory for passing through the intersection. The target trajectory of the host vehicle M is generated by thecontrol unit 156 by itself, for example, by the same method as the curveshape prediction unit 148 generates the expected route. In addition, thecontrol unit 156 uses the information acquired via thecamera 10 or the like to match the arrangement of the surrounding objects (signals, stop lines, road signs, etc.) on the map background and the actual arrangement of the surrounding objects to ensure that The precision of the target orbit.

图8及图9是示出在交叉路口中的右转时由交叉路口通过控制部142执行的处理的流程的一例的流程图。本流程图的处理在由行动计划生成部140基于地图上路径与本车辆M的当前位置而判定为到达了与本车辆M右转的预定的交叉路口相距规定距离的地点时开始。8 and 9 are flowcharts showing an example of the flow of processing executed by the intersection passingcontrol unit 142 when turning right at the intersection. The process of this flowchart is started when the actionplan generation unit 140 determines that it has reached a predetermined distance from a predetermined intersection where the host vehicle M turns right based on the route on the map and the current position of the host vehicle M.

首先,追随对象确定部146确定追随对象的前行车辆(步骤S100)。交叉路口通过控制部142判定是否存在(确定了)追随对象的前行车辆(步骤S102),在不存在(未确定出)追随对象的前行车辆的情况下,使凭自己通过控制部156起动,进行用于在交叉路口凭自己右转的控制(步骤S104)。First, the followingtarget specifying unit 146 specifies a preceding vehicle to be followed (step S100). The intersection passingcontrol unit 142 determines whether or not there is (determined) a preceding vehicle to follow (step S102 ), and if there is no (undetermined) preceding vehicle to follow, the self-passingcontrol unit 156 starts the vehicle , and control for turning right by yourself at the intersection is performed (step S104).

在存在追随对象的前行车辆的情况下,追随行驶控制部144判定在进行右转的交叉路口的跟前侧是否存在从本车辆M的附近没有中断地延伸到交叉路口为止的中央隔离带(步骤S106)。When there is a preceding vehicle to be followed, the followingtravel control unit 144 determines whether or not there is a median that extends from the vicinity of the host vehicle M to the intersection without interruption on the immediate side of the intersection where the right turn is made (step S106).

在存在上述那样的中央隔离带的情况下,追随行驶控制部144开始以高的确信度追随前行车辆(步骤S108)。具体而言,如前述那样。When there is a median as described above, the followingtravel control unit 144 starts following the preceding vehicle with a high degree of certainty (step S108 ). Specifically, it is as described above.

接着,追随行驶控制部144判定作为追随对象而确定的前行车辆是否在右转待转行车道停止着或者过去停止过(步骤S110)。在作为追随对象而确定的前行车辆在右转待转行车道停止着或者过去停止过的情况下,追随行驶控制部144确定追随该前行车辆而右转,使本车辆追随前行车辆而行驶直至通过交叉路口(步骤S112)。Next, the followingtravel control unit 144 determines whether or not the preceding vehicle identified as the following target has stopped in the right-turn lane or has stopped in the past (step S110 ). When the preceding vehicle identified as the following object is stopped in the lane to be turned right or has stopped in the past, the followingdriving control unit 144 determines to follow the preceding vehicle to turn right, and causes the host vehicle to follow the preceding vehicle and travel. until the intersection is passed (step S112).

在作为追随对象而确定的前行车辆未在右转待转行车道停止着且过去未在右转待转行车道上停止过的情况下,前行车辆监视部132识别前行车辆的转弯角度(步骤S114)。然后,转弯一致判定部150判定前行车辆的转弯角度是否偏离了预想路径中的转弯角度θ(步骤S116)。When the preceding vehicle identified as the following object has not stopped in the right-turn lane and has not stopped in the right-turn lane in the past, the precedingvehicle monitoring unit 132 recognizes the turning angle of the preceding vehicle (step S114). Then, the turningcoincidence determination unit 150 determines whether or not the turning angle of the preceding vehicle deviates from the turning angle θ on the expected route (step S116 ).

在步骤S116的判定处理的具体的内容中,与交叉路口的形状相应地,可能会如以下那样产生多种模式。In the specific content of the determination process in step S116, depending on the shape of the intersection, various patterns may be generated as follows.

(1)右转前方的道路仅存在一个的情况(1) When there is only one road ahead of the right turn

转弯一致判定部150在前行车辆的转弯角度超过了转弯角度θ加规定角度(例如10度左右)的情况下,判定为偏离了预想路径中的转弯角度θ。该判定专门用于在前行车辆进行U字形掉头的情况下中止追随。When the turning angle of the preceding vehicle exceeds the turning angle θ plus a predetermined angle (for example, about 10 degrees), the turningcoincidence determination unit 150 determines that the turning angle θ is deviated from the expected route. This determination is specifically used to stop following when the preceding vehicle makes a U-turn.

(2)右转前方的道路存在多个且预定的方向的道路是必要的转弯角度最小的道路的情况(2) When there are multiple roads ahead of the right turn, and the road in the predetermined direction is the road with the smallest necessary turning angle

转弯一致判定部150进行与(1)同样的处理。该判定用于在前行车辆进行U字形掉头或向转弯角度比预定的方向的道路大的道路行进的情况下中止追随。The turncoincidence determination unit 150 performs the same processing as (1). This determination is used to stop following when the preceding vehicle makes a U-turn or travels on a road with a larger turning angle than a predetermined direction.

(3)右转前方的道路存在多个且预定的方向的道路不是必要的转弯角度最小的道路的情况(3) When there are multiple roads ahead of the right turn and the road in the predetermined direction is not the road with the smallest turning angle necessary

转弯一致判定部150在前行车辆的转弯角度超过了预想路径中的转弯角度θ加规定角度(例如10度左右)的情况、或者前行车辆的转弯角度小于预想路径中的转弯角度θ减规定角度(例如10度左右)且前行车辆的速度为阈值Th1以上、转弯角速度小于阈值Th2的情况下,判定为偏离了预想路径中的转弯角度θ。前者的判定用于在前行车辆进行U字形掉头的情况下中止追随,后者的判定用于在前行车辆向转弯角度比预定的方向小的道路行进的情况下停止追随。The turncoincidence determination unit 150 is used when the turning angle of the preceding vehicle exceeds the turning angle θ on the expected route plus a predetermined angle (for example, about 10 degrees), or when the turning angle of the preceding vehicle is smaller than the turning angle θ on the expected route minus a predetermined angle When the speed of the preceding vehicle is equal to or greater than the threshold value Th1 and the turning angular velocity is less than the threshold value Th2, it is determined that the angle θ deviates from the expected route by the turning angle θ. The former determination is used to stop following when the preceding vehicle makes a U-turn, and the latter determination is used to stop following when the preceding vehicle is traveling on a road with a smaller turning angle than a predetermined direction.

在判定为前行车辆的转弯角度偏离了预想路径中的转弯角度θ的情况下,交叉路口通过控制部142向步骤S104推进处理。When it is determined that the turning angle of the preceding vehicle deviates from the turning angle θ on the expected route, the intersection passingcontrol unit 142 proceeds to step S104 .

在未判定为前行车辆的转弯角度偏离了预想路径中的转弯角度θ的情况下,交叉路口通过控制部142判定本车辆M是否通过了交叉路口(步骤S118)。在判定为本车辆M通过了交叉路口的情况下,交叉路口通过控制部142结束本流程图的处理,在判定为本车辆M未通过交叉路口的情况下,交叉路口通过控制部142向步骤S110返回处理。When it is not determined that the turning angle of the preceding vehicle deviates from the turning angle θ on the expected route, the intersection passingcontrol unit 142 determines whether or not the host vehicle M has passed through the intersection (step S118 ). When it is determined that the own vehicle M has passed the intersection, the intersection passingcontrol unit 142 ends the processing of this flowchart, and when it is determined that the own vehicle M has not passed the intersection, the intersection passingcontrol unit 142 proceeds to step S110 Return processing.

进入图9,在步骤S106中,在判定为不存在上述那样的中央隔离带的情况下,追随行驶控制部144也开始追随前行车辆(步骤S130)。在该情况的追随控制下,与步骤S108的控制相比,追随开始的时机变晚,或者与追随的前行车辆之间的车间距离变长。9 , in step S106 , when it is determined that the above-mentioned median barrier does not exist, the followingtravel control unit 144 also starts following the preceding vehicle (step S130 ). In the following control in this case, compared with the control in step S108, the timing of starting the following becomes later, or the inter-vehicle distance from the preceding vehicle to follow becomes longer.

接着,追随行驶控制部144判定作为追随对象而确定的前行车辆是否在右转待转行车道上停止着或者在过去停止过(步骤S132)。在作为追随对象而确定的前行车辆在右转待转行车道上停止着或者在过去停止过的情况下,追随行驶控制部144确定追随该前行车辆而右转,使本车辆追随前行车辆而行驶直至通过交叉路口(步骤S134)。Next, the followingtravel control unit 144 determines whether or not the preceding vehicle identified as the following object has stopped on the right-turn lane or has stopped in the past (step S132 ). When the preceding vehicle identified as the following object is stopped on the right-turn waiting lane or has stopped in the past, the followingdriving control unit 144 determines to follow the preceding vehicle and turns right, and causes the host vehicle to follow the preceding vehicle. And travel until passing through the intersection (step S134).

在作为追随对象而确定的前行车辆未在右转待转行车道上停止且在过去未在右转待转行车道上停止过的情况下,前行车辆监视部132识别前行车辆的转弯开始地点及转弯角度(步骤S136)。然后,转弯一致判定部150判定前行车辆的转弯开始位置是否偏离了预想路径中的转弯开始位置SP(步骤S138)。在步骤S138中得到了否定性的判定的情况下,转弯一致判定部150判定前行车辆的转弯角度是否偏离了预想路径中的转弯角度θ(步骤S140)。在步骤S138和步骤S140中的任一方得到了肯定性的判定的情况下,向步骤S104推进处理,交叉路口通过控制部142使凭自己通过控制部156起动,进行用于凭自己在交叉路口中右转的控制。这样,在前行车辆的转弯开始位置偏离了预想路径中的转弯开始位置SP的情况下,停止向该前行车辆的追随,由此例如能够快速地停止如图4所示的前行车辆m4那样追随向处于交叉路口CR的跟前的道路外区域HA行进的前行车辆,从而顺利地通过交叉路口。The precedingvehicle monitoring unit 132 recognizes the turning start point of the preceding vehicle when the preceding vehicle identified as the following object has not stopped on the right-turn lane and has not stopped on the right-turn lane in the past. and the turning angle (step S136). Then, the turncoincidence determination unit 150 determines whether or not the turn start position of the preceding vehicle deviates from the turn start position SP on the expected route (step S138 ). When a negative determination is obtained in step S138, the turningcoincidence determination unit 150 determines whether or not the turning angle of the preceding vehicle deviates from the turning angle θ on the expected route (step S140). When an affirmative determination is made in either step S138 or step S140, the process proceeds to step S104, and the intersection passingcontrol unit 142 activates the self-passingpassage control unit 156 to perform a self-use at the intersection. Control to turn right. In this way, when the turning start position of the preceding vehicle deviates from the turning start position SP on the expected route, by stopping the following to the preceding vehicle, for example, the preceding vehicle m4 shown in FIG. 4 can be quickly stopped. In this way, it follows the preceding vehicle traveling toward the off-road area HA in front of the intersection CR, and the intersection is smoothly passed.

在步骤S138和步骤S140这双方都得到了否定性判定的情况下,交叉路口通过控制部142判定本车辆M是否通过了交叉路口(步骤S142)。交叉路口通过控制部142在判定为本车辆M通过了交叉路口的情况下,结束本流程图的处理,在判定为本车辆M未通过交叉路口的情况下,向步骤S132返回处理。When both steps S138 and S140 are negatively determined, the intersection passingcontrol unit 142 determines whether or not the host vehicle M has passed through the intersection (step S142). The intersection passingcontrol unit 142 ends the process of this flowchart when it is determined that the own vehicle M has passed the intersection, and returns to step S132 when it is determined that the own vehicle M has not passed the intersection.

在作为上述流程图中的步骤S108、S112、S130、S134等的处理而使本车辆M追随前行车辆进行行驶时,也可以根据周边环境的变化而取消追随。在周边环境的变化中,可以列举行人在前行车辆与本车辆M之间横穿,在前行车辆通过了交叉路口后信号机变成了通行禁止(例如红灯)的状态等。另外,在取消了追随后,交叉路口通过控制部142可以凭自己使本车辆M通过交叉路口,也可以预先追踪前行车辆的行驶轨迹,在消除了周边环境的变化的(例如,在行人结束了横穿的、或信号机成为了允许通行的状态的)情况下基于所追踪的行驶轨迹来使本车辆M行驶。When the host vehicle M is driven to follow the preceding vehicle as the processing of steps S108, S112, S130, and S134 in the above-described flowchart, the following may be canceled according to changes in the surrounding environment. In the change of the surrounding environment, it can be listed that a person crosses between the preceding vehicle and the host vehicle M, and the traffic signal becomes a traffic prohibited (eg, red light) state after the preceding vehicle passes through the intersection. In addition, after canceling the pursuit, the intersection passingcontrol unit 142 may pass the host vehicle M through the intersection by itself, or may track the travel trajectory of the preceding vehicle in advance, and after the change in the surrounding environment is eliminated (for example, when the pedestrian ends The vehicle M is driven on the basis of the tracked traveling trajectory when the vehicle has crossed or the traffic signal has been allowed to pass.

根据以上说明的实施方式的自动驾驶控制装置100,在本车辆通过交叉路口的情况下,在本车辆行进的预定的方向为跨过相向车辆的前进道路而通过交叉路口的方向且在本车辆行驶的道路上存在中央隔离带时,使本车辆追随在本车辆的前方行驶且被推定出向预定的方向的行进意图的前行车辆而通过交叉路口,所以能够更顺利地使本车辆M通过交叉路口。According to the automaticdriving control device 100 of the above-described embodiment, when the host vehicle passes through the intersection, the predetermined direction in which the host vehicle travels is the direction in which the host vehicle crosses the road of the oncoming vehicle and passes through the intersection, and the host vehicle is traveling in the direction When there is a median belt on the road with the vehicle M, the host vehicle M can pass through the intersection more smoothly by following the preceding vehicle that is traveling in front of the host vehicle and whose travel intention is estimated to be in the predetermined direction and passes through the intersection. .

在上述的说明中,虽然关于左转时并没有言及,但也可以在左转时,也追随被推定出与本车辆同样地左转的意图的前行车辆而通过交叉路口。在该情况下,也可以进行与图9的流程图中的步骤S136~S140的处理同样的处理,在从转弯开始位置或转弯角度偏离了设想的情况下停止追随。In the above description, the time of turning left is not mentioned, but even when turning left, it is also possible to follow a preceding vehicle whose intention to turn left similarly to the own vehicle is estimated to pass through the intersection. In this case, the same processing as the processing of steps S136 to S140 in the flowchart of FIG. 9 may be performed, and the following may be stopped when the turning start position or turning angle deviates from the assumption.

另外,在上述的说明中,设为了在存在追随对象的前行车辆的情况下,不另外附带特别的条件地追随前行车辆而通过交叉路口的情形,但也可以仅在夜间或者仅在恶劣天气时追随前行车辆而通过交叉路口。这是因为,在这样的情况下,相机10等的感应能力比白天或者好天气时下降。In the above description, when there is a preceding vehicle to be followed, it is assumed that the vehicle follows the preceding vehicle and passes through the intersection without additional special conditions. However, it may be only at night or only in bad weather. In weather, follow the vehicle ahead and go through the intersection. This is because, in such a case, the sensing capability of thecamera 10 or the like is lower than that in the daytime or in good weather.
