Motor torque control device of electric vehicle

摘要

A motor torque control device of an electric vehicle sets creep torque in accordance with a vehicle speed sensed by a vehicle speed sensor, and sets acceleration torque in accordance with an accelerator control input sensed by an acceleration sensor. Then, the motor torque control device calculates a torque command value by adding the creep torque to the acceleration torque. It is therefore possible to quickly raise the acceleration torque immediately when an accelerator is operated to start the vehicle. It is also possible to prevent a sharp decrease in the torque command value since the torque command value reflects the creep torque even after the start of the vehicle.
