Regenerative braking control method for rear drive electric wagon

The invention provides a regenerative braking control method for a rear drive electric wagon. In the initial braking period, maximum motor braking torque is adopted for energy recovery braking, when the rotating speed of a motor reaches first rotating speed, the motor braking torque is gradually reduced, and when the rotating speed of the motor reaches second rotating speed, motor braking force is removed. The method has the advantages that the method is compatible with different braking modes and suitable for rainy days, slippery road surfaces and other road conditions, and a driver can select the motor braking force suitable for current road conditions according to the road surface real-time conditions; the motor braking torque changes smoothly and is not sporadic, and the driving habits of the driver are fully considered. 本发明提供种后驱电动货车的再生制动控制方法，在制动初期，采用最大的电机制动力矩进行能量回收制动，在电机转速达到第转速时，逐渐减小电机制动力矩，在电机转速达到第二转速时，撤掉电机制动力。本发明的优点在于，兼容不同的制动模式，适用雨天以及路面湿滑等路况，驾驶员还可根据路面实时工况，选择适合当前路况的电机制动力；电机制动力矩平滑的变化，不会出现时有时无的情况，充分考虑驾驶员驾驶
