ABSTRACT:
The left rear wheel is driven with the left motor and the right rear wheel is driven with the right motor. Selection of a control mode is made from a first control mode in which the left and right motors are driven in common and a second control mode in which the left and right motors are driven discretely and separately. A region in which the motors are driven is so arranged as to be altered in accordance with the running state of the vehicle, such as the lateral acceleration acting upon the vehicle body, the road surface friction coefficient .mu., the vehicle speed, the steered angle of the steering wheel, etc. A clutch can be disposed to couple the left and right wheels to be driven with the motors when a predetermined condition is met. When the motor is of a hydraulic type, the accumulator for accumulating the hydraulic pressure is disposed to thereby drive the secondarily driven wheels by the motors by taking advantage of the hydraulic pressure from the accumulator, in addition to the driving of the engine, leading to an increase in acceleration with a force larger than the force generated by the engine.
