<p>A generator for vehicle 2 is connected to an end of a transmitting wire 1 through a generator-side signal transmitting and receiving circuit 3 which has a transistor 33 and a comparator 34. An ECU 5 is connected to the other end of the transmitting wire through a vehicle-side signal transmitting and receiving circuit 4 which has a switching transistor 42 and a comparator 45. The comparator 34 receives frequency signals from the transistor 42, and the comparator 45 receives a voltage signal from the transistor 33. Thus the generator control signal and the generator condition signal are transmitted by the same transmitting wire. <IMAGE></p> |
