Abstract
A regenerative braking system for a car in which the pumping capacity of a pump/motor is responsive to the inner pressure of a hydraulic circuit by determining exhaust/engine brake equivalent torque corresponding to car speed and gear position when the car speed exceeds a predetermined speed. A manual operating device for an exhaust brake is or is not operated, so that the engine of the car is decoupled, the hydraulic oil circuit is closed, the pumping capacity is controlled, and an electromagnetic clutch is coupled to accumulate the deceleration energy of the car into the high pressure accumulator as if an exhaust/engine brake works.
