A control device for hybrid vehicle is provided with property alter means 88 that is operative based on whether or not an EV running mode is set and alters a given property used for determining demanded output torque TOUTt of a transmission mechanism 10 by referring to an accelerator opening Acc. This suppresses occurrence of engine startup to meet a requirement for the EV running mode to be initiated. The property alter means 88 alters the given property such that during an EV running mode turn-on state, demanded output torque TOUTt determined based on the accelerator opening Acc has a lower value than that set for an EV running mode turn-off state. That is, this causes a drop in sensitivity of demanded output torque TOUTt determined based on the accelerator opening Acc. Thus, the occurrence of engine startup induced upon depressive operation of an accelerator pedal during the EV running mode is suppressed.
A control device for a hybrid vehicle including an engine and an electric motor, establishing a motor running state with only the electric motor serving as a drive-power source, and being switched to an engine running state with the engine enabled to serve as a main drive-power source for running the vehicle, if a demanded drive-force relevant value demanded to a vehicle exceeds a given value during the motor running state,
