Abstract
【解決手段】駆動系は、駆動源(エンジン,MG)および駆動源と駆動輪(前輪,後輪)との間でトルクを伝達する伝達機構を含む。伝達機構は、駆動系を構成する要素の間でトルクを伝達する係合状態と伝達しない解放状態とに切替える少なくとも1つのクラッチ(K0クラッチ,K2クラッチ,LUC)を含む。ECUは、駆動輪の側から駆動系に過大なトルクが掛かり得る負荷状態を検出し、過大なトルクが掛かり得る負荷状態であると検出された場合(ステップS111〜S113,S121,S122,S125でYESの場合)、所定のクラッチを解放する(ステップS123,S124,S126,S127)。
【選択図】図3
Description
車両1において、制動時には、駆動源およびパワートレーンを含む駆動系にねじりトルクが掛かる。本実施の形態のように、駆動源としてエンジン10に加えてMG20を備えるようなハイブリッドシステムの場合、および、駆動輪(前輪51、後輪52)への出力をさらに減速することが可能な副変速機41を備える場合は、掛かるねじりトルクはさらに過大となる。
以上、説明した実施の形態を以下にまとめる。
次に上述した実施の形態の変形例を説明する。
