The invention discloses a multi-scene adaptive real-time speed limiting method. The multi-scene self-adaptive real-time speed limiting method comprises the following steps: acquiring chassis information of a vehicle and information of an obstacle in front of the vehicle; wherein the chassis information of the vehicle comprises the initial speed of the vehicle, the current actual speed of the vehicle and the upper and lower limits of acceleration; the information of the obstacle in front of the vehicle comprises the distance between the obstacle and the vehicle and the speed of the obstacle; an application scene is judged based on the chassis information of the vehicle and the obstacle information in front of the vehicle, and the corresponding expected planned acceleration of the vehicle is determined based on the application scene; and taking the expected planned acceleration of the vehicle as the initial speed of dynamic planning. The multi-scene self-adaptive real-time speed limiting method can ensure quick and timely response, improves the driving stability and real-time performance, and is suitable for various application scenes.

    本申请公开了一种多场景自适应实时限速方法。所述多场景自适应实时限速方法包括步骤:获取自车底盘信息和自车前方障碍物信息;其中,自车底盘信息包括自车初速度、自车的当前的实际速度和加速度上下限;自车前方障碍物信息包括障碍物与自车之间的距离、障碍物的速度;基于自车底盘信息和自车前方障碍物信息判断应用场景,并基于应用场景确定相应的自车的预期规划加速度;以及,以自车的预期规划加速度作为动态规划的初速度。所述多场景自适应实时限速方法能够保证快速、及时的响应,提高行车稳定性和实时性,并适用于多种应用场景。
