A generator for vehicle is connected to an end of a transmitting wire through a generator-side signal transmitting and receiving circuit which has a transistor and a comparator. An ECU is connected to the other end of the transmitting wire through a vehicle-side signal transmitting and receiving circuit which has a switching transistor and a comparator. The comparator receives frequency signals from the transistor, and the comparator receives a voltage signal from the transistor. Thus, the generator control signal and the generator condition signal are transmitted by the same transmitting wire.
