The invention discloses an energy recovery hierarchical control method and system for a pure electric heavy commercial vehicle, and relates to the technical field of electric vehicles, and the control method comprises the following steps: judging whether the vehicle driving state is a sliding state or a braking state according to the vehicle quasi state of the electric vehicle; confirming an energy feedback set torque value according to the vehicle driving state; whether the energy feedback set torque value exceeds the limit or not is judged, and whether the ABS is activated or not is judged; and outputting a final energy feedback set torque value. The handle control switch is additionally arranged, so that the control convenience of a driver is improved, meanwhile, the energy recovery size is optimized according to the characteristics of the driving motor and the driving axle direction torque limiting value, and the smoothness and high efficiency of a vehicle and the service life of the vehicle driving axle are ensured.

    本发明公开了一种纯电动重型商用车能量回收分级控制方法和系统,涉及电动车技术领域,本发明的控制方法包括以下步骤:电动车车辆准状态,判断车辆行驶状态为滑行或者制动状态;根据车辆行驶状态,确认能量回馈设定扭矩值;判断能量回馈设定扭矩值是否超限,判断ABS是否激活;输出最终的能量回馈设定扭矩值。本发明增加手柄操纵开关提升驾驶员操纵的便利性,同时根据驱动电机特性、驱动桥方向扭矩限值优化能量回收大小,确保车辆的平顺性、高效性,以及车辆驱动桥使用寿命。
