Abstract
The embodiments described herein relate to control apparatuses for hybrid vehicles which permit starting of an engine and a shift-down action of a transmission, while assuring a reduction of heat generated by a clutch and an improvement of a response of the hybrid vehicle to a vehicle 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 the motor drive mode to the engine drive mode, a rate of change of the input speed of said transmission is lower than when only the shift-down action is required to be performed, such that the rate of change of the input speed is relatively low when the input speed of the transmission to be established upon completion of the shift-down action is relatively high.
