NOVELTY - The device (1) has a motor generator (MG1) mechanically connected with a front wheel (Wf) of a vehicle chassis. One end of the rear-wheel (Wr) is connected with another motor generator (MG2) electrically connected with motor generator. A flywheel (FW) is arranged to store the kinetic energy of vehicle chassis. The motor generator is mechanically connected with the front wheel and rear-wheel of vehicle chassis. A control-apparatus (CU) prohibits the fastening of clutches (CL1,CL2), when operation of power running drive and regeneration drive of motor generator is prevented.    USE - Drive device mounted in vehicle e.g. hybrid type motor vehicle and hybrid type fuel cell electric vehicle.    ADVANTAGE - The regenerative braking of wheel can be increased without providing kinetic energy storage device and increasing the number of motor generators. The reduction in the kinetic energy of the kinetic-energy storage device which arises by accompanying motor generator with respect to kinetic energy storage device can be prevented. Since motor generators connected to a different wheel are independently controlled, the running performance and efficiency of vehicle can be improved. The fastening of clutches can be prohibited, when power running drive and regeneration drive of motor generator is not performed. The deterioration of controllability and efficiency of the electric motor which unnecessarily arises by accompanying wheel with respect to motor generator can be prevented. The noise vibration by the cogging of motor generator can be prevented. The vehicle can be efficiently driven according to the state of vehicle and the state of electrical storage device. The drag loss of motor generator which carries out regeneration drive can be reduced by cutting away kinetic-energy storage device. As the braking force and driving force of vehicle is stably added to rear and front wheel, the stability of vehicle, turning property, and road ability can be improved.
