A regeneration control device for a hybrid vehicle includes an internal combustion engine, driving wheels drivable by the internal combustion engine, a motor for additionally supplying electric power for driving the driving wheels, a transmission between the engine, motor and driving wheels and an accumulator for supplying electric power to the motor, which causes the motor to work, while braking the vehicle, as a generator whose output is returned to the accumulator which in turn stores electric energy regenerated depending upon the deceleration degree. The control device also has calculating means for determining the degree of downward slope of a road whereon the vehicle is running and correcting means for correcting a regenerable energy amount according to the downward slope determined by the calculating means when using the motor as the generator, the output of which is thus corrected and returned to charge the accumulator in such a way that the accumulator may not rapidly be charged to its full capacity, thus preventing regeneration from being ineffective due to the full charge of the accumulator.
