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.

[ What is claimed is:] [1.]1. A hybrid electric vehicle, comprising:a generator rotated by a driving force of an engine to thereby generate power;a battery to which the power generated by said generator is charged;a motor for generating a driving force to driving wheels of the vehicle by the power supplied from said battery and regenerating energy by using rotational power from the driving wheels to generate power and charge said battery when said vehicle is being braked;an actual charge level sensing device for sensing an actual charge level of said battery;a chargeable power setting device for setting chargeable power in accordance with a sensed value of the actual charge level of said battery by said actual charge level sensing device;a deceleration instruction device for instructing said vehicle to decelerate;a deceleration torque sensing device for sensing a deceleration torque required by said deceleration instruction device;a regenerated power computing unit for setting regenerated power to be regenerated by said motor during a regenerative braking according to a sensed value of the required deceleration torque by said deceleration torque sensing device; anda control device for supplying the power generated by said motor to said generator to thereby drive said generator to rotate said engine when an accelerator pedal for supplying fuel to the engine has not been depressed and when chargeable power set by said chargeable power setting device is less than the regenerated power computed by said regenerated power computing unit while said motor is regenerating the energy.
