Four-wheel drive electric vehicle control device
Abstract:
A four-wheel drive electric vehicle control device is provided for a four-wheel drive electric vehicle that has a motor/generator as a drive source, and an electronically controlled coupling provided on the drive power transmission path leading from the drive source to the front and rear wheels. The four-wheel drive hybrid vehicle has a 4WD control unit that outputs to the electronically controlled coupling a transmission torque command value to bring about the four-wheel drive state, in accordance with the vehicle state. The 4WD control unit has a regenerative control intervention-coordinating controller that, when regenerative control by the motor/generator has intervened during the four-wheel drive state, brings the transmission torque of the electronically controlled coupling to zero before initiating regenerative control.
