Description
電池40などの故障に起因して電池40の充電を禁止すべき状況(電池ECU60が電池40の充電を禁止すべきと判定した場合)においては、MG10の回生電力が電池40に供給されないようにすることが望まれる。一方、電池40の充電を禁止すべき状況においても、車両1を退避走行させるためには、SMR30をオン状態に維持して電池40からMG10への放電を許容することが望まれる。
上述の実施の形態においては、MG10が駆動輪2からの動力で回転している状態で電池40の充電が禁止されている場合であって、かつモータ回転速度NMが第1閾値N1以上かつ第2閾値N2未満の領域に含まれる場合には、ゼロトルク制御が実行される。しかしながら、当該領域において実際に電池40が充電されていることが検出された場合には、充電禁止を実現するために、ゼロトルク制御ではなく三相オン制御を実行するようにしてもよい。
上述の図6および図7においてはステップS10の処理後にステップS20の処理を行なう例を示したが、ステップS10の処理前にステップS20の処理を行なうようにしてもよい。
