Regeneration control device, hybrid automobile, regeneration control method, and program

摘要

The purpose of the invention is to improve drivability when the regenerative torque of an electric motor is used as a braking force. Provided is a hybrid automobile comprising: a deceleration comparison unit (32) for, when a regenerative torque generated by regenerative power generation in an electric motor is used as a braking force during deceleration of the hybrid automobile traveling using only the electric motor, comparing a preset target deceleration and an actual deceleration caused by the regenerative torque generated by the regenerative power generation; and a regeneration control unit (30) for, in a case where the result of comparison of the deceleration comparison unit (32) indicates that a state in which the actual deceleration is equal to or lower than the target deceleration occurs in a predetermined pattern though the electric motor is generating the maximum regenerative torque, causing the automobile to travel using both an engine and the electric motor in a cooperative manner during the next deceleration after the current deceleration has been finished, such that the engine braking in the engine and the regeneration torque of the electric motor are both used as a braking force.
