Zusammenfassung:A motion control device independently drives left and right wheels by calculating a wheel torque value from a difference between a reference vehicle state quantity calculated from driver operation information or an operation instruction of a higher driving device and an actual vehicle state quantity calculated from information regarding a motion and a posture of the vehicle, and controlling a plurality of motors based on the wheel torque value. Furthermore, the motion control device calculates a momentum error from a difference between a reference momentum calculated based on a wheel rotation speed and a tire steering angle and an actual momentum calculated based on the information regarding the motion and the posture of the vehicle, extracts a momentum error caused by a torque difference of the motor from the calculated momentum error, calculates a wheel torque correction amount based on the extracted momentum error caused by the torque difference of the motor, adds the wheel torque correction amount to the wheel torque value, and outputs a wheel torque command to the plurality of motors.
