VEHICLE CONTROL DEVICE AND DRIVING SYSTEM FOR ELECTRIC VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a vehicle control device and a driving system for an electric vehicle capable of controlling the optimum driving force, according to the operating conditions for each vehicle, in the electric vehicle that drives each wheel by a separate and independent electric motor.

SOLUTION: The vehicle control device 100 has a driving force calculating unit 129 that calculates a forward and backward control forth FXi', (driving force of each wheel) that should be controlled with respect to each wheel; and an electric motor controller 131 that controls a current value i, supplied to in-wheel motors 30FL, 30FR, 30RL and 30RR, based on a calculated backward and forward control force FXi', of each wheel (driving force), by using a difference Fexin the actual backward and forward force FΛXand a target backward and forward force F*Xof the electric vehicle; a lateral force difference FeYin an actual lateral force FΛYand a target vehicle lateral force F*Y; a difference MeZin an actual yaw moment MΛZand a target yaw moment M*Z; and a tire operation availabilityηiin each wheel, determined on the basis of a grounding load in each wheel, with respect to the actual backward and forward force FΛXand the actual lateral force FΛYof the wheel.
