ABSTRACT:
A regenerative braking system for a car in which when a hydraulic circuit is not operated, effective maximum displacement controlling current and minimum displacement controlling current for a pump/motor in the hydraulic circuit are studied on the basis of a variation of the sensed displacement angle when the maximum permissible current and the minimum operating current previously given to a displacement angle controlling electromagnetic proportional control valve are respectively decreased and increased stepwise. A displacement controlling current per a unit capacity for the control valve is determined.
