To provide a rotary electric machine unit capable of highly accurately detecting a magnet temperature of a rotary electric machine even while the rotary electric machine is stopped, etc., a vehicle and a control method for the rotary electric machine unit.SOLUTION: A torque sensor 72 of a rotary electric machine unit 110 is provided on a power transmission path between a rotary electric machine 24 and a target object 32 and detects a rotary electric machine torque that is an output torque from the rotary electric machine 24 or an input torque to the rotary electric machine 24. A control device 40 estimates a magnet temperature Tmg of the rotary electric machine 24 on the basis of a rotary electric machine current (an input current or an output current of the rotary electric machine 24) and the rotary electric machine torque. A vehicle 10 is capable of including the rotary electric machine unit 110.SELECTED DRAWING: Figure 1

    【課題】回転電機が停止している場合等にも回転電機の磁石温度を高精度に検出することが可能な回転電機ユニット、車両及び回転電機ユニットの制御方法を提供する。【解決手段】回転電機ユニット110のトルクセンサ72は、回転電機24と対象物体32の間の動力伝達経路上に設けられて、回転電機24からの出力トルク又は回転電機24への入力トルクである回転電機トルクを検出する。制御装置40は、回転電機電流(回転電機24の入力電流又は出力電流)と回転電機トルクとに基づいて、回転電機24の磁石温度Tmgを推定する。車両10は、回転電機ユニット110を有することができる。【選択図】図1
