The invention provides a torque distribution method for an electric vehicle. The torque distribution method comprises the steps of S1, S2, S3 and S4. S1, a vehicle speed threshold value, a wheel rotating speed change rate threshold value and a vehicle slip rate threshold value are set according to a vehicle; s2, vehicle driving data are collected, and the actual wheel rotating speed change rate and the actual vehicle slip rate are calculated according to the vehicle driving data; s3, comparing the actual wheel rotating speed change rate and the actual vehicle slip rate obtained through calculation with a wheel rotating speed change rate threshold value and a vehicle slip rate threshold value to obtain a vehicle driving condition; and S4, distributing the torque occupancy rates of the front wheels and the rear wheels of the vehicle according to the running vehicle condition and the actual slip rate of the vehicle. According to the electric vehicle torque distribution method, the slip rate can be calculated, and on the basis of the distribution torque output, the vehicle can be quickly out of trouble.
本发明提供一种电动车辆扭矩分配方法,包括:S1、S2、S3和S4。S1根据车辆设定车速阈值、车轮转速变化率阈值和车辆滑移率阈值;S2采集车辆行驶数据,根据车辆行驶数据计算车轮实际转速变化率和车辆实际滑移率;S3将计算得到的车轮实际转速变化率、车辆实际滑移率和车轮转速变化率阈值、车辆滑移率阈值对比,得到车辆行驶车况;S4根据行驶车况和车辆实际滑移率分配车辆前轮和车辆后轮的扭矩占用率。本发明的电动车辆扭矩分配方法可以实现滑移率的计算并基于此分配扭矩输出,以实现车辆的快速脱困。
