Regeneration control device of hybrid electric vehicle

The invention provides a regeneration control device of a hybrid electric vehicle, which is able to sufficiently charge a battery with power regenerated as a result of the regenerative braking and effectively perform the regenerative braking, and which is also able to ease the burden of a friction brake. If chargeable power set by a chargeable power setting device according to a charging 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.
