技术领域technical field
本发明涉及智能路线规划技术领域，尤其涉及可进行智能路线规划与节能的一种行车避堵系统与方法。The invention relates to the technical field of intelligent route planning, in particular to a traffic congestion avoidance system and method capable of intelligent route planning and energy saving.
背景技术Background technique
传统中，车辆(例如家用轿车、大巴、客车、货车等)上会装配许多智能的产品(例如全球卫星定位系统、电子地图)，以提高行车的效率。行车的效率有可能受到行车路线受阻的影响，例如道路雍塞、道路事故等路况不佳的情况。Traditionally, vehicles (such as family cars, buses, passenger cars, trucks, etc.) are equipped with many intelligent products (such as global satellite positioning systems, electronic maps) to improve driving efficiency. The efficiency of driving may be affected by blocked driving routes, such as road blockages, road accidents and other poor road conditions.
目前的产品(如高德地图、百度地图等)似乎可用来解决前述的问题，使得前述车辆能够避免受到路况不佳的影响。The current products (such as Gaode map, Baidu map, etc.) seem to be used to solve the aforementioned problems, so that the aforementioned vehicles can avoid being affected by poor road conditions.
然而，前述车辆的驾驶员必须随时关注前述产品显示的动态，导致所述驾驶员存在驾驶安全隐患。另外，所述产品仅能显示路况状态，而无法解决所述车辆针对实际即时的路况进行路线二次智能选择与优化。传统技术除了有上述的缺失之外，更有如下的缺点，罗列如下：However, the driver of the aforementioned vehicle must always pay attention to the dynamics displayed by the aforementioned product, causing the driver to have driving safety hazards. In addition, the product can only display the state of road conditions, but cannot solve the problem of secondary intelligent selection and optimization of routes for the vehicle based on actual and real-time road conditions. In addition to the above-mentioned deficiencies, the traditional technology has the following disadvantages, which are listed as follows:
传统中，当前述车辆行进时，在前述驾驶员选择行驶路线之后，该些产品便会维持在所述行驶路线。当所述行驶路线的前方遇到拥堵、限行、限流、事故等路况状态影响行驶时，该些产品无法自动为前述驾驶员变更路线。Traditionally, when the aforementioned vehicle is moving, after the aforementioned driver selects the driving route, these products will maintain the driving route. These products cannot automatically change the route for the aforementioned driver when road conditions such as congestion, traffic restrictions, traffic restrictions, and accidents affect the driving ahead of the driving route.
传统中，前述驾驶员在前述车辆运行中，尤其是高速路上行驶，需要在前述车辆的中控屏幕上操作或者进行开关按键操作，存在一定安全隐患与操作不便。Traditionally, the aforementioned driver needs to operate on the central control screen of the aforementioned vehicle or perform switch button operations when the aforementioned vehicle is running, especially on a highway, which poses certain potential safety hazards and inconvenient operation.
传统中，该些产品无法根据该些路况状态，考量能耗(例如油耗与电耗)，以提供未来的能耗趋势给前述驾驶员参考。举例而言，纯电力驱动的电动汽车的续航里程，因受限于电池容量，若遇到拥堵缓行，将会导致预估的续航里程无法满足实际需求，对使用者将带来极大的不便。Traditionally, these products cannot consider energy consumption (such as fuel consumption and electricity consumption) according to these road conditions, so as to provide future energy consumption trends for the driver's reference. For example, the cruising range of a purely electric vehicle is limited by the battery capacity. If it encounters congestion and slows down, the estimated cruising range cannot meet the actual demand, which will bring great inconvenience to users. .
虽然有新式产品提出可以针对电耗、能耗进行分配；但仅只是单纯进行电耗与能耗的规划，而并未进一步考量实时路况信息对于前述车辆的电耗、能耗的影响，从而无法将能源合理分配，这个在纯电动汽车中尤为重要。Although there are new products that can allocate power consumption and energy consumption; but they only plan power consumption and energy consumption without further consideration of the impact of real-time road condition information on the power consumption and energy consumption of the aforementioned vehicles, so it is impossible Rational distribution of energy is especially important in pure electric vehicles.

请参阅图3，是本发明第三实施例的行车避堵方法的流程示意图。在图3，该行车避堵方法的步骤起始在步骤S31，根据路况信息，以自动或手动的方式决定是否执行行车避堵方案，若决定执行行车避堵方案，执行步骤S32。在该步骤中，该路况信息是来自例如交警微博、交警路况官网、实时新闻等互联网信息、收音机信息。在自动模式中，当前方产生例如大流量、事故、恶劣天气、施工等该路况信息时，可透过与一个设定阀值的比对，决定是否自动或手动启动行车避堵方案。前述中，该阀值相关于路况的车速、拥堵指数等。因此，当前方拥堵指数大于或等于设定阀值，或者前方车速小于或等于对应的设定阈值时，执行行车避堵的各步骤。在手动模式中，因驾驶员目视发现前方拥堵可手动地提出执行行车避堵方案的请求。Please refer to FIG. 3 , which is a schematic flowchart of a traffic congestion avoidance method according to a third embodiment of the present invention. In FIG. 3 , the steps of the traffic congestion avoidance method start at step S31. According to the road condition information, whether to implement the traffic congestion avoidance scheme is determined automatically or manually. If it is decided to implement the traffic congestion avoidance scheme, step S32 is executed.

In the automatic mode, when road conditions such as heavy traffic, accidents, bad weather, construction, etc. are generated ahead, it can be compared with a set threshold to decide whether to automatically or manually activate the traffic congestion avoidance plan. In the foregoing, the threshold is related to the vehicle speed, congestion index, etc. of the road conditions. Therefore, when the congestion index ahead is greater than or equal to the set threshold, or the speed of the vehicle ahead is less than or equal to the corresponding set threshold, each step of avoiding traffic congestion is executed. In the manual mode, since the driver visually finds the congestion ahead, he can manually request to execute the traffic congestion avoidance plan.
步骤S32，发出路线更新请求，并根据路线更新请求确认前方路况监控信息。由于在前述步骤的执行过程中，取得的该实时路况监控信息有可能存在时间差，导致无法获得及时的信息，故在本步骤中，需要再次向实时路况监控模块和/或远程监控单元确认该实时路况监控信息，以确定当前为最新或最即时的该路况信息。当该实时路况监控信息显示当前路况确实为一拥堵状态，执行步骤S34。当该实时路况监控信息显示当前路况为非拥堵状态，则执行步骤S33。Step S32, sending out a route update request, and confirming the road condition monitoring information ahead according to the route update request. Since the real-time road condition monitoring information obtained may have a time difference during the execution of the aforementioned steps, resulting in the inability to obtain timely information, so in this step, it is necessary to confirm the real-time traffic condition monitoring module and/or remote monitoring unit again. Traffic monitoring information to determine the latest or most real-time traffic information.

In this embodiment, the planned route provided in the route planning option can be filtered according to evaluation conditions such as the shortest distance, the fastest time, and the lowest cost. Here, taking the lowest cost as an example, the evaluation of adoption cost includes external cost evaluation and internal cost evaluation. Among them, the external cost is generated by collecting charging information related to the planned route through the Internet connection; and the internal cost is the energy consumption cost of the vehicle itself, and the energy consumption cost can be obtained through vehicle information and Real-time road condition monitoring information is evaluated to obtain an energy consumption value, and the cost of using the vehicle on the planned route is calculated based on the latest information such as fuel costs and electricity costs obtained from the Internet. Finally, the last-pass cost is estimated based on the cost of extrinsic costs, intrinsic costs, or both. Potential routes can be screened out based on the evaluation conditions, and provided to the driver through the route planning instruction module.
步骤S36，根据选择执行路线规划选项中的一种规划路线。若根据选择的结果，车辆执行的路线发生变更,进入步骤S37，若车辆执行的路线不发生变更，则维持原有的路线和行车方案。In step S36, one of the route planning options is executed according to the selection to plan a route. If according to the selected result, the route executed by the vehicle changes, go to step S37; if the route executed by the vehicle does not change, then maintain the original route and driving plan.
步骤S37，提取一车辆的整车信息，演算该整车信息与当前执行的规划路线，判断整车剩余能源是否足以执行选定的规划路线。在本步骤中，该整车信息包括车辆运行情况和车辆能源使用情况，车辆能源使用情况包括车辆的能耗情况与整车剩余能源请况(例如整车剩余电量、或者整车剩余油量)等。当整车剩余能源足够使车辆执行完成该规划路线，则按照当前行车状态执行该规划路线。当整车剩余能源不足以使车辆执行完成该规划路线，执行步骤S38。Step S37, extracting the vehicle information of a vehicle, calculating the vehicle information and the current planned route, and judging whether the remaining energy of the vehicle is sufficient to execute the selected planned route. In this step, the vehicle information includes vehicle operation status and vehicle energy usage, and vehicle energy usage includes vehicle energy consumption and vehicle remaining energy status (such as the remaining power of the vehicle or the remaining fuel capacity of the vehicle) Wait. When the remaining energy of the vehicle is sufficient to enable the vehicle to complete the planned route, the planned route is executed according to the current driving state. When the remaining energy of the vehicle is insufficient to enable the vehicle to complete the planned route, step S38 is performed.
步骤S38，向驾驶员发出提醒，请求执行能源调整程序。当驾驶员确认执行该能源调整程序,进入步骤S39。当不执行该能源调整程序，则维持该车辆的运行模式。于另一实施例中，若该驾驶员在一定时间内并未主动选择执行该能源调整程序，则可以选择维持不执行该能源调整程序或自动地执行该能源调整程序。Step S38, sending a reminder to the driver, requesting to execute the energy adjustment program. When the driver confirms to execute the energy adjustment program, enter step S39. When the energy adjustment program is not executed, the running mode of the vehicle is maintained. In another embodiment, if the driver does not actively choose to execute the energy adjustment program within a certain period of time, he may choose not to execute the energy adjustment program or automatically execute the energy adjustment program.
步骤S39，执行该能源调整程序，以调整该车辆的能源损耗率。举例而言，在不同新能源车型提供不同的节能等级，具体节能等级定义可以参照图4。根据本发明的行车避堵方法可藉由将计算出的路况速度值V2(在路况实际速度线S2上)与最优能耗速度目标值V1(在最优能耗速度目标线S1上)进行比值，若V2＞V1，则将最优能耗速度值V3设定为V1；反之，若V2＜V1,将最优能耗速度值V3设定为V2，进而可以计算出一个最优能耗速度线S3。在另一实施例中，当该驾驶员猛踩加速踏板并超过一阀值，但踩的时间小于预设的阀值时，允许加速度超过最优能耗加速度值V3，可以满足该驾驶员超车需求。上述的三条速度线S1、S2、S3，其中最优能耗速度目标线S1为一直线，其上的速度值为固定值、路况实际速度线S2会随着路况及时间而动态变化，避堵系统会根据实际路况变化情况与前一周期的路况实际速度线S2进行比较。在另一实施例中，若最新时间周期与上一周期的路况实际速度线S2相比的变化率超过一数值，则对路况实际速度线S2进行更新，否则不做更新。另外，最优能耗速度线S3可根据路况实际速度线S2变化情况而做调整，阀值根据最优能耗速度线S3最大的速度值做相应调整，例如若在最优能耗速度线S3中最大加速度需求增加，则由第一阀值更改至第二阀值。Step S39, execute the energy adjustment program to adjust the energy consumption rate of the vehicle. For example, different new energy vehicles provide different energy-saving levels, and the definition of specific energy-saving levels can refer to Figure 4. According to the traffic jam avoiding method of the present invention, the calculated road condition speed value V2 (on the road condition actual speed line S2) and the optimal energy consumption speed target value V1 (on the optimal energy consumption speed target line S1) can be carried out. Ratio, if V2>V1, set the optimal energy consumption speed value V3 to V1; otherwise, if V2<V1, set the optimal energy consumption speed value V3 to V2, and then calculate an optimal energy consumption rate Speed line S3. In another embodiment, when the driver slams on the accelerator pedal and exceeds a threshold, but the stepping time is less than the preset threshold, the acceleration is allowed to exceed the optimal energy consumption acceleration value V3, which can satisfy the driver's need for overtaking. need. Among the three speed lines S1, S2, and S3 mentioned above, the optimal energy consumption speed target line S1 is a straight line, the speed value on which is a fixed value, and the actual speed line S2 of the road conditions will change dynamically with the road conditions and time to avoid traffic jams. The system will compare the actual road condition speed line S2 of the previous cycle according to the actual road condition changes. In another embodiment, if the rate of change between the latest time period and the road condition actual speed line S2 in the previous period exceeds a certain value, the road condition actual speed line S2 is updated, otherwise no update is performed. In addition, the optimal energy consumption speed line S3 can be adjusted according to the changes in the actual speed line S2 of the road conditions, and the threshold value is adjusted according to the maximum speed value of the optimal energy consumption speed line S3. For example, if the optimal energy consumption speed line S3 If the maximum acceleration demand increases, the first threshold value is changed to the second threshold value.
在另外一实施例中，在步骤S39之后更包含取消步骤，根据取消指令或判断所述车辆的驾驶行为，结束所述能源调整程序。若驾驶员需要恢复正常行驶时，可通过声音或开关按键的方式输入该取消指令。该车辆的驾驶行为可以例如若驾驶员急速踩下加速踏板并超过系统设置的阀值，并超过系统设置的时间阀值，即车辆可以在超过一定时间内以较高的速度行驶时，结束能源调整程序。In another embodiment, after the step S39, a canceling step is further included, and the energy adjustment procedure is ended according to the canceling instruction or judging the driving behavior of the vehicle. If the driver needs to resume normal driving, the cancel command can be input by voice or switch button. The driving behavior of the vehicle can be, for example, if the driver quickly depresses the accelerator pedal and exceeds the threshold value set by the system, and exceeds the time threshold value set by the system, that is, when the vehicle can travel at a higher speed for a certain period of time, the energy will be terminated. Adjustment Program.
在另外一实施例中，在步骤S39之后更包含另一取消步骤，根据所述实时路况监控信息，结束所述能源调整程序、或改变节能等级继续执行所述能源调整程序。若根据实时路况监控信息，发现前方路况改善，并通过与行车模块的交互，发现正常行驶能耗可以满足需求，或者调整节能等级后可以满足要求，此时系统可以将此信息通过路线规划指示模块传递给驾驶员。若驾驶员在一定时间内确认结束能源调整程序或改变节能等级，则根据驾驶员的指示结束能源调整程序或改变节能等级，否则将继续保持当前能耗方式行驶。若驾驶员在一定时间内并未响应路线规划指示模块的提示信息，则系统再次提醒，若继续不响应，则保持当前能耗方式行驶。In another embodiment, another canceling step is further included after step S39 , according to the real-time road condition monitoring information, the energy adjustment program is terminated, or the energy saving level is changed to continue the energy adjustment program. If according to the real-time road condition monitoring information, it is found that the road conditions ahead have improved, and through the interaction with the driving module, it is found that the normal driving energy consumption can meet the demand, or the energy saving level can be adjusted to meet the requirements, then the system can pass this information through the route planning instruction module passed on to the driver. If the driver confirms to end the energy adjustment program or change the energy-saving level within a certain period of time, then end the energy adjustment program or change the energy-saving level according to the driver's instructions, otherwise it will continue to drive in the current energy consumption mode. If the driver does not respond to the prompt information of the route planning instruction module within a certain period of time, the system will remind again. If the driver continues to fail to respond, the driver will keep driving in the current energy consumption mode.
综上所述，本发明的行车避堵系统和方法，通过响应不佳的路况，为驾驶员规划替代路线，并根据整车情况确认当前车辆剩余的能源是否可以在当前能耗下依据新的路线到达目的地，并在当前剩余能源不足的情况下调整能源损耗率，节省能源，从而达到规避不良路况并保证车辆能够成功达到目的地的目的。To sum up, the traffic congestion avoidance system and method of the present invention plans an alternative route for the driver by responding to poor road conditions, and confirms whether the remaining energy of the current vehicle can use the new energy consumption under the current energy consumption according to the vehicle condition.
