<P>PROBLEM TO BE SOLVED: To provide a motor control method and a motor controller of a parallel hybrid electric vehicle in which torque ripple of an engine can be reduced effectively by controlling the motor utilizing a current signal calculated based on an acceleration command and an estimated inertial moment of the motor. <P>SOLUTION: The motor control method of a parallel hybrid electric vehicle comprises a step for calculating the estimated inertial moment (J<SP>#</SP><SB>eq</SB>) of the motor, a step for calculating a forward compensation current (i<SB>q-FF</SB>) based on the estimated inertial moment (J<SP>#</SP><SB>eq</SB>) of the motor and an acceleration command (a<SP>*</SP>), a step for calculating a final current command (i<SB>qs</SB><SP>*</SP>) based on the forward compensation current (i<SB>q-FF</SB>) and the output current (i<SB>q-PI</SB>) from a speed controller calculated based on the acceleration command (a<SP>*</SP>), and a step for controlling the motor based on the final current command. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
