Description
図1は、実施形態の車両100の構成の例示的な図である。図1に示されるように、車両100は、駆動系構成として、エンジン1と、変速機2と、差動機構3と、車輪4,5と、を備えている。エンジン1から出力された動力は、変速機2および差動機構3を介して車輪4,5に伝達される。なお、実施形態では、車両100は、駆動源としてエンジン1のみを備えた例が示されているが、これに限定されない。例えば、車両100は、動力源としてエンジン1とモータとを備えたハイブリッド車であってもよいし、駆動源としてモータのみを備えた電気自動車であってもよい。
エンジン1は、シリンダー内で燃料を爆発燃焼させ、その熱エネルギによって回転動力(トルク)を発生する内燃機関である。エンジン1は、変速機2に連結された出力シャフト1aを有しており、出力シャフト1aから出力された回転動力は、変速機2に入力される。
