| description | To enable a gear stage of a downshift destination to be set appropriately in accordance with a heat load of an engine connection/disconnection device, when control of engine start is started during downshift of an automatic transmission.SOLUTION: A destination-gear stage is extended to a low gear stage side when an engine is started by a starting method B more than when the engine is started by a starting method A during downshift. In the starting method B in which the engine is fired to self-rotate in a stage in which a rotation speed Ne of the engine is low rotation, slip engagement of a clutch K0 (an engine connection/disconnection device) is small, so that increase of a rotation speed Nmg of an electric motor is large when the destination gear stage is the low gear stage, and therefore even when a difference in speed between the speed and the rotation speed Ne of the engine is large, the clutch K0 is unlikely to be damaged by heat loads by slip engagement. This enables the destination gear stage to be switched to the low gear stage and to be shifted down to a target gear stage quickly.SELECTED DRAWING: Figure 11
【課題】自動変速機のダウンシフト中にエンジン始動制御が開始された場合に、エンジン断接装置の熱負荷に応じてダウンシフト先のギヤ段が適切に定められるようにする。【解決手段】ダウンシフト時に始動方式Ｂでエンジンが始動させられる場合の行き先ギヤ段は、始動方式Ａでエンジンが始動させられる場合に比較して低ギヤ段側に拡張される。エンジン回転速度Ｎｅが低回転の段階から着火して自力回転させる始動方式Ｂでは、クラッチＫ０（エンジン断接装置）のスリップ係合が少ないため、行き先ギヤ段が低ギヤ段で電動機回転速度Ｎｍｇの上昇幅が大きく、エンジン回転速度Ｎｅとの速度差が大きい場合でも、スリップ係合による熱負荷でクラッチＫ０が損傷する恐れはない。このため、行き先ギヤ段を低ギヤ段として、目的とするギヤ段まで速やかにダウンシフトさせることができる。【選択図】図１１ |
