Zusammenfassung:	To provide a control device of an on-vehicle motor unit which is capable of appropriately driving and controlling an electric oil pump in a low temperature environment without referring to an oil temperature.SOLUTION: A motor unit 1 mounted on a vehicle comprises: a motor 2 having a plurality of coils arranged around a motor shaft; a transmission mechanism for transmitting driving force of the motor; a housing which accommodates the motor and the transmission mechanism; an electric oil pump 9 which conveys oil in the housing; and a coil temperature sensor 33 for detecting a temperature of the motor coil. A motor control device 110 comprises a motor control part 113 for driving and controlling the motor and a pump control part 114 for driving and controlling the electric oil pump. The pump control part estimates the temperature of the oil on the basis of an outside air temperature and the coil temperature and determines a start timing of the electric oil pump on the basis of the estimated oil temperature.SELECTED DRAWING: Figure 3 【課題】低温環境において、オイル温度を参照せずに電動オイルポンプを適切に駆動制御可能な車両搭載モータユニットの制御装置を提供する。【解決手段】車両に搭載されるモータユニット１は、モータ軸周りに並ぶ複数のコイルを有するモータ２と、モータの動力を車軸に伝達する伝達機構と、モータおよび伝達機構を収容するハウジングと、ハウジング内のオイルを搬送する電動オイルポンプ９と、モータコイルの温度を検出するコイル温度センサ３３と、を有する。モータ制御装置１１０は、モータを駆動制御するモータ制御部１１３と、電動オイルポンプを駆動制御するポンプ制御部１１４とを有する。ポンプ制御部は、外気温とコイル温度とからオイルの温度を推定し、推定されるオイル温度に基づいて電動オイルポンプの起動タイミングを決定する。【選択図】図３
