METHOD FOR REDUCING TORSIONAL SHOCK OF DRIVING SYSTEM OF ELECTRIC VEHICLE

A method for reducing torsional shock of a driving system of an electric vehicle is provided. In the method, torsional torque of a part of the driving system is calculated by applying motor torque to a motor under the condition that a parking gear is engaged and monitoring a motor speed. Reverse tor...

Zusammenfassung:	A method for reducing torsional shock of a driving system of an electric vehicle is provided. In the method, torsional torque of a part of the driving system is calculated by applying motor torque to a motor under the condition that a parking gear is engaged and monitoring a motor speed. Reverse torsional torque having the same magnitude as the calculated torsional torque is applied to the part of the driving system when release of the parking gear is requested, and then the parking gear is released to reduce shock caused by torsion of the part of the driving system when the parking gear is released.
