The invention provides an energy recovery braking method for an intelligent driving system, and the method comprises the steps: obtaining a negative torque request value TrqReq of an actuator power assembly system corresponding to a deceleration braking request TargetAx of the function of the intelligent driving system according to a strategy when a current ESC responds to a deceleration request of the intelligent driving system; when the intelligent driving system needs to request deceleration braking, an ESC deceleration braking request TargetAx and a power assembly system negative torque request TrqReq are requested at the same time, and the function of achieving the deceleration braking effect required by the function is achieved. Under the condition that the current energy recovery control strategy of the power assembly system is not changed, the ESC deceleration braking request TargetAx and the power assembly system negative torque request TrqReq are requested at the same time, energy recovery under the function work of the intelligent driving system is achieved, energy consumption of the vehicle is reduced, and the driving distance of the vehicle is prolonged.

    本发明提供了一种用于智能驾驶系统的能量回收制动方法,通过根据当前的ESC响应智能驾驶系统的减速度请求时的策略,结合智能驾驶系统功能的减速制动请求Target_Ax,得到与之相对应的执行器动力总成系统的负扭矩请求值TrqReq;在智能驾驶系统功能需请求减速制动时,同时请求ESC减速制动请求Target_Ax和动力总成系统负扭矩请求TrqReq,实现了达到功能需求的减速制动效果的功能。在不改变动力总成系统当前的能量回收控制策略下,通过同时请求ESC减速制动请求Target_Ax和动力总成系统负扭矩请求TrqReq,实现了智能驾驶系统功能工作下的能量回收,降低了车辆的能量消耗和延长车辆的行驶距离。
