When controlling engine starting in travelling and down-shift and speed change controls to process simultaneously, impact property and delay performance can be met in all scenes.The control setup of FR motor vehicle driven by mixed power possesses: driving engine (Eng), dynamotor (MG), first clutch (CL1), automatic speed variator (AT), second clutch (CL2) and simultaneously processing selecting control unit (Fig. 6).About processing selecting control unit (Fig. 6) while of this, when engine start request overlaps with down-shift and speed change request, the moment of torsion that motor can export after down-shift and speed change is more than engine starting moment of torsion, this while processing selecting control unit carry out engine starting simultaneously and control and down-shift and speed change control, the moment of torsion that motor can export after down-shift and speed change is less than engine starting moment of torsion, this while processing selecting control unit first carry out engine starting control after carry out down-shift and speed change control. |
