PROBLEM TO BE SOLVED: To allow for vehicle evacuation operation by performing first fail-safe operation not with output stop, when a cooling device is normal.SOLUTION: A motor system controller determines, in a MCU22, whether or not an abnormality occurs in a temperature sensor 41 for detecting the temperature of a motor 4, and whether or not an abnormality occurs in a cooling device 30. When a determination is made that an abnormality does not occur in a cooling device 30, and that an abnormality occurs in the temperature sensor 41, the MCU22 performs first fail-safe control with no output stop, and when a determination is made that an abnormality occurs in the cooling device 30, and that an abnormality occurs in the temperature sensor 41, performs second fail-safe control for stopping the output of the motor 4.

    【課題】冷却装置が正常である場合には出力停止を伴わない第1のフェールセーフ制御が実行されるので、車両退避運転が可能となる。【解決手段】モータシステム制御装置は、MCU22において、モータ4の温度を検出する温度センサ41に異常が生じているか否かの判定、および、冷却装置30に異常が生じているか否かの判定を行っている。そして、MCU22は、冷却装置30に異常が生じていないと判定され、かつ、温度センサ41に異常が生じていると判定されると、モータ4の出力停止を伴わない第1のフェールセーフ制御を実行し、冷却装置30に異常が生じていると判定され、かつ、温度センサ41に異常が生じていると判定されると、モータ4の出力停止を行わせる第2のフェールセーフ制御を実行する。【選択図】図1
