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 action
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 passing
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 following
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 following
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 preceding
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 preceding
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 following
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 the
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 following
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 following
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 turning
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 turning
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 turning
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 turn
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 matching
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 turning
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 passing
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 passing
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 following
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 following
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 following
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 following
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 preceding
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 turning
(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 turn
(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 turn
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 passing
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 passing
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 following
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 following
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 preceding
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 passing
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 passing
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 automatic
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 the
