The invention relates to the field of electric vehicle control, and provides a brand-new energy recovery control method for a pure electric rear wheel drive vehicle. When the vehicle is in a sliding or braking state, a motor achieves a part of braking effect by applying reverse torque and charges a battery to reduce power consumption and improve the economy of the whole vehicle. And meanwhile, asthe energy recovery strength of driving wheels is scientifically controlled, the situation that the driving wheels of the vehicle are locked in the energy recovery process is avoided, and the safety of the whole vehicle is improved.

    本发明涉及电动汽车控制领域,针对纯电动后驱车提出一种全新的能量回收控制方法。当车辆处于滑行或制动状态时,电机通过施加反向力矩达到一部分的制动效果并对电池进行充电以减少电耗提升整车的经济性。同时由于科学的控制了驱动轮能量回收的强度不会使车辆出现在能量回收过程中驱动轮抱死的情况,提高整车安全性。
