ABSTRACT:
An apparatus and method for controlling energy feedback for electric vehicles includes acquiring an accelerator-pedal travel value, a brake-pedal travel value and a current vehicle speed value, and determining whether the brake-pedal travel value is equal to 0%. Feedback torque based on the current vehicle speed value and the brake-pedal travel value with various conditions is then calculated. Mechanical energy generated by the feedback torque T is converted into electric energy and transmitted to battery of the electric vehicle for storing. Accordingly, the endurance mileage of electric vehicle may be effectively prolonged and the utilization efficiency of battery is improved.
