The invention discloses a vehicle braking force calculation method. The method comprises the following steps of (1) acquiring vehicle braking force parameter information,(2) calculating the braking deceleration of the vehicle according to the braking force parameter information of the vehicle, and (3) calculating to obtain the initial braking force Fa of the vehicle according to the vehicle braking deceleration and the vehicle weight. By means of the calculation method, the braking force of the motor is calculated in real time, what is ensured is that the vehicle speed is decreased to the crawling target vehicle speed when the distance between the vehicle and the preceding vehicle is proper, on one hand, electric energy can be recycled as much as possible, on the other hand, accelerator stepping again for acceleration is avoided, and meanwhile safety can be considered.

    本发明公开了一种车辆制动力的计算方法,包括以下步骤:(1)获取车辆制动力参数信息;(2)根据车辆制动力参数信息计算车辆制动减速度;(3)根据车辆制动减速度和车重计算得到车辆初步制动力F。通过上述计算方法,实时计算电机的制动力,确保在距离前车适当的距离时降至蠕行目标车速,一方面可以尽可能多的回收电能,另一方面避免了再次踩油门加速,同时还能兼顾安全性。
