Zusammenfassung:To control a rotor phase of a motor without mechanically separating the motor from a driving wheel, and to improve vehicle start performance so that a motor output torque becomes the maximum region.SOLUTION: A vehicle control device includes a first driving motor 11, a second driving motor 12, an axle 3 connected to a driving wheel 4, and a planetary gear mechanism 20 in which a ring gear 23 is connected to the first driving motor 11, a sun gear 21 is connected to the second driving motor 12 and a carrier 22 is connected to the axle 3, respectively; can change each rotor phase of both of the driving motors 11 and 12 while stopping the rotation of the axle 3; and allows a phase adjustment section 52 to adjust each rotor of the first and second driving motors 11 and 12 to a phase region of which the motor output torque becomes the maximum region while stopping the rotation of the axle, when a control start condition including determination of the stop of the vehicle by a stop determination section 51 is satisfied.SELECTED DRAWING: Figure 1 【課題】モーターを駆動輪から機械的に切り離すことなく、モーターのローター位相を制御してモーター出力トルクが最大域になるようにして、車両の発進性能を向上させる。【解決手段】第1の駆動用モーター11と、第2の駆動用モーター12と、駆動輪4に連結された車軸3と、リングギア23が第1の駆動用モーター11に、サンギア21が第2の駆動用モーター12に、キャリア22が車軸3に、それぞれ連結された遊星歯車機構20とを有し、車軸3を回転停止させたままで両駆動用モーター11,12の各ローター位相を変更可能な車両であって、停止判定部51により車両の停止が判定されたことを含む制御開始条件が成立したら、位相調整部52が車軸を回転停止させたままで第1及び第2の駆動用モーター11,12の各ローターを何れもモーター出力トルクが最大域となる位相領域に調整する。【選択図】図1
