<p>The present invention has an object to improve a regenerative ratio while suppressing a change in a regenerative braking force caused by a change in a power generation voltage, in a regenerative control system of a vehicle which serves to regenerate kinetic energy of the vehicle to electrical energy at the time of deceleration running of the vehicle so that the electrical energy thus regenerated is supplied to a low voltage system circuit and a high voltage system circuit in an alternate manner. In order to achieve this object, a regenerative control system of a vehicle according to this invention is constructed such that in a system which generates electrical energy of a low voltage suitable for a low voltage system circuit and electrical energy of a high voltage suitable for the high voltage system circuit in an alternate manner by making use of kinetic energy of a vehicle when the vehicle is in a deceleration running state, a ratio between a period of time to generate the low voltage electrical energy and a period of time to generate the high voltage electrical energy is decided in accordance with a deceleration required of the vehicle, and a power generation voltage is duty controlled according to the ratio thus decided.</p> |
