The invention discloses an opposite coming vehicle collision avoidance device under a left-turn working condition, and the device comprises a vehicle sensing unit which is used for collecting the image and state information of a front opposite coming vehicle through a sensor, and the relative movement condition of the front opposite coming vehicle and a self vehicle; the vehicle information unit is used for detecting the state information of the vehicle and judging whether the vehicle turns left or not so as to trigger the planning control unit; the state information of the vehicle comprises coordinates, a course angle and a vehicle speed of the vehicle; the planning control unit is used for performing collision prediction according to the detection information output by the vehicle sensing unit and the state information of the vehicle output by the vehicle information unit, and driving the vehicle execution unit to perform corresponding collision avoidance operation according to a prediction result; and the vehicle execution unit is used for performing braking or steering collision avoidance operation according to the prediction result of the planning control unit. According to the invention, aiming at the expansion of the automatic emergency brake function of the urban intersection, the vehicle can be automatically prevented from colliding with the vehicle coming from the opposite direction when turning left to pass through the intersection scene.
本发明公开了一种左转工况下的对向来车碰撞避免装置,包括:车辆感知单元,用于通过传感器采集前方对向来车的图像和状态信息,以及前方对向来车与自车的相对运动情况;车辆信息单元,用于检测自车的状态信息,并判断自车是否处于左转以触发规划控制单元;所述自车的状态信息包括自车的坐标,航向角和车速;规划控制单元,用于根据车辆感知单元输出的检测信息和车辆信息单元输出的自车的状态信息进行碰撞预测,并根据预测结果驱动车辆执行单元做出对应的避撞操作;车辆执行单元,用于根据规划控制单元的预测结果进行制动或转向避撞操作。本发明是针对城市路口自动紧急刹车功能的扩展,使车辆在左转通过路口场景时能够自动避免与对向来车的碰撞。
