Description
好適には、前記変速部の変速が必要とされる時であって且つその変速が制限される時には、駆動力源の出力を抑制するので、車両用駆動装置の負荷を抑制するために変速部の変速が必要とされるときに、その変速が制限されたとしても、車両用駆動装置の耐久性を向上させることができる。
また、前記変速部で必要とされる変速とは、前記電動機の温度上昇を抑制する為に必要とされる前記変速部での変速であるので、変速部の変速によって電動機の温度上昇が抑制される一方で、その変速部の変速が制限されたとしても駆動力源の出力を抑制することで電動機の温度が適切に下げられる。
また、前記変速部で必要とされる変速とは、前記変速部の作動油の温度上昇を抑制する為に必要とされる前記変速部での変速であるので、変速部の変速によって変速部の作動油の温度上昇が抑制される一方で、その変速部の変速が制限されたとしても駆動力源の出力を抑制することで変速部の作動油の温度が適切に下げられる。
また、前記変速部での変速が制限される時とは、前記車両用駆動装置を構成する回転要素が許容回転速度を超える時であるので、前記車両用駆動装置を構成する回転要素が許容回転速度を超える時には、駆動力源の出力の低下量を多くして電動機の温度や変速部の作動油の温度を速やかに下げることができる。
