摘要： In a front wheel-and rear-wheel drive vehicle having a motor such as an engine to develop a mechanical energy and to drive either one of front road wheels or rear road wheels of the vehicle and another motor such as an electric motor to develop the mechanical energy and to drive the other of the front road wheels or the rear road wheels, a drive controller is provided to control a driving force of the other motor, a front-and-rear road wheel velocity difference detector is provided to detect a front-and-rear road wheel velocity difference (&Dgr;N) between the front and rear road wheels, a driver's vehicular acceleration intention detector such as an accelerator pedal depression sensor is provided to detect a manipulated variable (PS) representing a driver's vehicular acceleration intention, a target torque calculating section calculates a target torque outputted from the other motor in accordance with the detected front-and-rear road wheel velocity difference and the manipulated variable, another motor driven road wheel acceleration detector is provided to detect an acceleration (dNR) of another motor driven road wheel by means of the other motor, and a corrector corrects the target torque on the basis of the acceleration of the other motor driven road wheel and the manipulated variable representing the driver's vehicular acceleration intention. The drive controller provides a motor drive torque (T*) for the other motor on the basis of the target torque which is corrected by the target torque corrector.
