Zusammenfassung:The invention provides a regenerative braking wheel-inversion-prevention control method for an electric vehicle and belongs to the field of electric vehicle braking. Whether the electric vehicle meetsa regenerative braking condition or not is judged based on accelerator pedal opening degree signals, gear signals, battery SOC signals, motor rotating speed signals, vehicle speed signals and ABS signals; if the electric vehicle meets the regenerative braking condition, further judgment is conducted; and if the electric vehicle does not meet the regenerative braking condition, a regenerative braking torque sent to a driving motor is zero. The further judgment comprises the steps that: when an ABS is not activated, and a vehicle speed difference value does not exceed a vehicle speed differencevalue threshold value, a motor regenerative braking torque obtained through MAP graph table look-up is sent to the driving motor; when the ABS is activated or the vehicle speed difference value exceeds the vehicle speed diffe
