To reduce power charged into a battery without lowering brake forces of motor generators at the braking of a vehicle, in the vehicle in which outputs of a planetary gear mechanism for merging the power of the two motor generates are transmitted to wheels.SOLUTION: In a control device of a vehicle including a planetary gear mechanism 4 for merging the power of two motor generators MG1, MG2, and comprising a transmission mechanism 2 for transmitting outputs of the planetary gear mechanism 4 to wheels 1, when power charged into a battery becomes larger than the charge-allowable power of the battery by driving the two motor generators MG1, MG2 by MTPA control at a rotation speed at which a mechanical loss of the transmission mechanism 2 becomes minimum, the two motor generators MG1, MG2 are driven at a rotational speed at which the mechanical loss of the transmission mechanism 2 is increased more than a rotational speed at which the mechanical loss of the transmission mechanism 2 becomes minimum.SELECTED DRAWING: Figure 1 【課題】２つのモータジェネレータの動力を合流させる遊星歯車機構の出力が車輪へ伝達される車両において、車両の制動時に、モータジェネレータの制動力を減少させることなくバッテリへ充電される電力を減少させる。【解決手段】２つのモータジェネレータＭＧ１，ＭＧ２の動力を合流させる遊星歯車機構４を含み、遊星歯車機構４の出力を車輪１へ伝達する伝達機構２を備える車両の制御装置であって、車両の制動時に、２つのモータジェネレータＭＧ１，ＭＧ２を、伝達機構２の機械的な損失が最小となる回転速度でＭＴＰＡ制御によって駆動させると、バッテリへ充電される電力がバッテリの充電許容電力より大きくなる場合には、伝達機構２の機械的な損失が最小となる回転速度よりも伝達機構２の機械的な損失を増大させた回転速度で２つのモータジェネレータＭＧ１，ＭＧ２を駆動させる。【選択図】図１
