PROBLEM TO BE SOLVED: To simplify a structure for adjusting torque distributions between a first driving shaft and a second driving shaft.SOLUTION: When a rotation difference occurs between a left driving wheel 63 and a right driving wheel 64, frequencies of AC currents in common which are flown to stator coils 13 and 23 of first and second induction machines 10 and 20 are controlled by an inverter 30 commonly used so as to control torque distributions between the left driving wheel 63 and the right driving wheel 64.EFFECT: Switching operation for controlling the AC currents of the stator coil 13 and switching operation for controlling the AC currents of the stator coil 23 need not to be performed independently by individual inverters and can be performed by one inverter 30 commonly used, so that the operation can be simplified.SELECTED DRAWING: Figure 1
【課題】第1駆動軸と第2駆動軸のトルク配分を調整するための構成を簡略化する。【解決手段】左駆動輪63と右駆動輪64に回転差が生じる場合に、共用インバータ30により第1及び第2誘導機10、20のステータ巻線13、23に流す共通の交流電流の周波数を制御することで、左駆動輪63と右駆動輪64のトルク配分を制御する。【効果】ステータ巻線13の交流電流を制御するためのスイッチング動作と、ステータ巻線23の交流電流を制御するためのスイッチング動作とを別々のインバータで独立して行う必要がなく、一台の共用インバータ30に共通化して簡略化することができる。【選択図】図1
