The invention provides an automobile braking speed planning method and electronic equipment, and relates to the technical field of electric automobile control. According to the specific implementation scheme, the method comprises the following steps that S1, the predicted parking time period of a target vehicle is determined based on the first expected braking distance and the real-time vehicle speed of the target vehicle; wherein the first expected braking distance is the braking distance of the target vehicle under the condition that no vehicle is in front; s2, the first expected braking distance is corrected based on the predicted parking time period, the real-time vehicle speed of the vehicle in front of the target vehicle and the safe vehicle distance between the target vehicle and the vehicle in front of the target vehicle, and a second expected braking distance of the target vehicle is obtained; and S3, determining a braking speed plan of the target vehicle based on the second expected braking distance, the safe vehicle distance and the battery recovery power of the target vehicle. According to the technical scheme, recovery of the braking energy of the vehicle is not limited to the ideal working condition that no vehicle exists in front any more, and recovery of the braking energy in the vehicle following environment is achieved.

    本公开提供了一种汽车制动速度规划方法和电子设备,涉及电动汽车控制技术领域。具体实现方案包括以下步骤:S1:基于目标车辆的第一预期制动距离和实时车速,确定目标车辆的预测停车时段;其中,第一预期制动距离为目标车辆在前方无车情况下的制动距离;S2:基于预测停车时段、目标车辆的前车的实时车速以及目标车辆与前车的安全车距,对第一预期制动距离进行修正,得到目标车辆的第二预期制动距离;S3:基于第二预期制动距离、安全车距以及目标车辆的电池回收功率,确定目标车辆的制动速度规划。根据本公开的技术方案,可以使得车辆制动能量的回收不再局限于前方无车的理想工况,实现了跟车环境下的制动能量的回收。
