Vehicle power generating apparatus

摘要

To provide a vehicle power generating apparatus capable of transmitting plural kinds of control signals from an external control device (7) to a generated voltage control unit (3) provided in a generator (1) for power generation control while curbing increases in the size of apparatus or wiring required and without degrading the noise reduction characteristics, a generated voltage control device (3) is normally disposed integrally with a generator (1) for maintaining the generated voltage at a predetermined target level. For transmission of a vehicle condition signal from an external control device (7) to the generated voltage control device, the vehicle condition signal is converted into a binary pulse train signal before being transmitted. The generated voltage control device (3) holds the binary pulse train signal received or a vehicle condition signal decoded from the binary pulse signal until the next reception. Thereby, complicated power generation control can be achieved with a small amount of communications. <IMAGE>
