A control apparatus for a hybrid vehicle for generating an appropriate amount
of
regeneration energy during deceleration. A control apparatus for a hybrid vehicle
including an engine and electric motor for driving the hybrid vehicle wherein the
engine comprises cylinders capable of deactivated operations and the motor executes
regenerative braking when the vehicle is decelerating. The control apparatus of
the present invention includes a cylinder deactivation determination device for
determining whether or not the vehicle speed is appropriate for executing the cylinder
deactivated operation, a regeneration amount calculating device for detecting whether
the vehicle state is appropriate for regeneration and calculates the amount of
regeneration; and further includes a compensation amount calculating device that
compensates the amount of regeneration based on an all cylinder deactivated operation
and the engine rotation speed.
