The invention provides an electric vehicle sliding feedback torque control method. The method comprises the steps that the sliding feedback torque control requirement of a vehicle is obtained; in response to the acquisition of the coasting feedback torque control demand, determining a torque-up request value based on a wheel operating state, and/or acquiring at least one additional torque-up value via a vehicle control unit (VCU); determining a maximum target negative torque value based on the torque-up request value, the at least one further torque-up value, and a real-time feedback torque value; and the maximum target negative torque value serves as sliding feedback torque to be transmitted to a driving motor so as to execute torque control. The invention further provides a corresponding electric vehicle sliding feedback torque control system and a vehicle. According to the method and the system, the method and the system can be easily implanted into an existing VCU torque control framework, supplementary torque control can be carried out on the sliding feedback process on the basis of an existing torque control function, and the problem that wheels of the electric vehicle rotate reversely in the sliding feedback process is solved.

    本发明提出了一种电动车辆滑行回馈扭矩控制方法,包括:获取本车辆的滑行回馈扭矩控制需求;响应于所述滑行回馈扭矩控制需求的获取,基于车轮操作状态确定升扭矩请求值,和/或经由整车控制器VCU获取至少一个另外的升扭矩值;基于所述升扭矩请求值、所述至少一个另外的升扭矩值和实时回馈扭矩值确定最大目标负扭矩值;和将所述最大目标负扭矩值作为滑行回馈扭矩传递给驱动电机以执行扭矩控制。本发明还提出了相应的电动车辆滑行回馈扭矩控制系统和车辆。根据本发明的方法和系统易于植入已有的VCU扭矩控制架构中,并且能够在已有的扭矩控制功能的基础上针对滑行回馈过程进行补充的扭矩控制,解决电动车辆在滑行回馈过程中的车轮反转的问题。
