Patent ID: 7411362

Claim:
A control device of a motor-driven 4WD vehicle which controls the vehicle such that one of front wheels and rear wheels of the vehicle are driven by an engine and the other of the front wheels and the rear wheels are driven by a motor if necessary, the control device comprising: means for generating a first 3-phase AC electricity of a first rating voltage using rotation power of the engine; means for lowering the first 3-phase AC electricity into a second DC electricity of a second rating voltage which is lower than the first rating voltage; means for rectifying the first 3-phase AC electricity and supplying a third DC electricity of a third rating voltage after rectification to the motor; and means for being supplied with the second DC electricity and for being charged, wherein the means for generating has a function of generating the first 3-phase AC electricity when the means for generating is driven by the engine, and also a function of rotating as a motor when a fourth 3-phase AC electricity of a fourth rating voltage is supplied to the means for generating, wherein the means for lowering is also a means for boosting a fifth DC electricity of a fifth rating voltage accumulated in a battery to the fourth 3-phase AC electricity, and wherein the means for generating generates a driving force by the fourth 3-phase AC electricity, and the engine is started by the driving force.
