Abstract
【解決手段】この動力伝達制御装置は、動力源として内燃機関E/GとモータM/Gとを備えたハイブリッド車両に適用され、手動変速機M/Tと、摩擦クラッチC/Tと、減速比切替機構とを備える。減速比切替機構は、「M/Gの出力軸と接続される第1軸」に対する「M/Tの出力軸と接続される第2軸」の減速比を変更可能となっている。第1軸に対する第2軸の減速比を変更することにより、M/Gの出力軸に対する駆動輪の減速比が変更される。運転者がクラッチペダルCPを操作している間に減速比を変更する作動が実行される。即ち、運転者は、何らかの操作を行っている間に減速比変更作動に伴うショックを受けることなり、運転者は係るショックを感知し難くなる。
【選択図】図1
Description
図1は、本発明の実施形態に係る動力伝達制御装置(以下、「本装置」と称呼する。)を搭載した車両の概略構成を示している。この車両は、動力源として内燃機関とモータジェネレータとを備えたハイブリッド車両であり、本装置は、トルクコンバータを備えない手動変速機と摩擦クラッチとを備える。即ち、本装置は、上述した「HV−MT車用動力伝達制御装置」である。
上述のように、MG接続切替作動の際、M/Gの出力軸から駆動輪へのトルクの伝達が一時的に遮断され得る。従って、MG接続切替作動に伴うショック(車両前後方向の加速度の変化)が不可避的に発生する。係るショックの発生は、運転者に不快感を与える。
上述したように、本装置では、M/Tの変速段を変更するために運転者が操作を行っている間にMG接続切替作動が実行される。具体的には、クラッチペダルCPが操作されている間(踏み始めから戻し終わりまでの間)にMG接続切替作動が実行される。即ち、運転者は、クラッチペダルCPを操作している間にMG接続切替作動に伴うショックを受けることなる。従って、運転者が係るショックを感知し難くなる。
