Abstract
Embodiments described herein relate to control apparatuses for hybrid vehicles which permit starting the engine and a shift-down action of the transmission while assuring not only a reduction of the heat generated by a clutch, but also an improvement in the response of the vehicle to an operator's desire for high drivability. In one embodiment, the control apparatus controls the hybrid vehicle such that when the transmission is required to be shifted down while the hybrid vehicle is switched from a motor drive mode to an engine drive mode, a time of initiation of the shift-down action of the transmission is delayed by a longer length of time when a temperature of the clutch upon initiation of an engine starting control to start the engine is relatively high than when the temperature is relatively low. Various other embodiments of control apparatuses for hybrid vehicles are also described.
