When the driver heavily depresses an accelerator pedal to start a hybrid
vehicle in an engine stop condition, the control of the invention waits
until elapse of a preset wait time and then starts outputting a torque
equivalent to a preset torque demand to a ring gear shaft or a
driveshaft. The preset wait time is determined not to make the driver
feel uncomfortable with a poor response. This arrangement desirably
shortens a time period when the vehicle acceleration is restricted due to
insufficient power output until the engine starts to output sufficient
power and make significant contribution to the vehicle acceleration. The
control of the invention thus desirably prevents the driver from feeling
the unexpectedly slow acceleration.
