Abstract:
A control system for a vehicle generator comprising:a first detector for detecting a running condition of a vehicle and producing a signal representative thereof; a second detector for detecting whether vehicle electrical equipments are ON or OFF and producing a signal representative thereof; and a controller responsive to the signals from the first detector and the second detector for controlling a field current of the generator thereby controlling an output voltage of the generator; wherein the controller is programmed to: send to the generator, if the vehicle electrical equipments are OFF and the vehicle is in a running condition other than a decelerating condition, a generation command value that is a first target voltage lower than a normal generation voltage; send to the generator, if the vehicle electrical equipments are OFF and the vehicle is in the decelerating condition, a generation command value that is a second target voltage higher than the normal generation voltage; and send to the generator, if one of the vehicle electrical equipments is ON, a generation command value that is a third target voltage lower than the normal generation voltage and higher than the first target voltage.
