Abstract
An apparatus for controlling a motor of a hybrid electric vehicle comprises a motor control unit and an electric control unit. The motor control unit is for controlling the motor under the control of the electric control unit. The electric control unit is for calculating a motor torque based on accelerator pedal position and a change thereof. The electric control unit also executes predetermined software. The software comprises instructions for: determining an accelerator pedal position and a change thereof; calculating a motor torque based on the accelerator pedal position; low-pass filtering the motor torque based on a filtering constant selected from a plurality of predetermined constants; and, controlling the motor based on the low-pass filtered motor torque.
