Abstract
A regeneration control device of a hybrid electric vehicle can sufficiently charge a battery with power regenerated as a result of the regenerative braking and effectively perform the regenerative braking, and which can also ease the burden of a friction brake. If chargeable power set by a chargeable power setting device according to an actual level of the battery becomes lower than regenerated power computed by a regenerated power computing unit during the regenerating operation of a motor, the power regenerated by the motor is supplied to a generator. This drives the generator to cause an engine to run an engine brake without the supply of fuel.
