Abstract

PURPOSE:To drive an alarm even when an acceleration pedal is not given by a driver at the time of backward driving of a vehicle by connecting a controller, an acceleration pedal switch, and a contact of a relay that is worked through a backward switch, in series, and by arranging the alarm on the backward switch. CONSTITUTION:An acceleration pedal switch 11 is placed between a key switch 3 and a controller 7 in series, while a forward switch 5a and a backward switch 5b are connected in parallel with the acceleration pedal switch 11, and the other end of the forward switch 5a is connected a coil 13a of a forward relay 13, while the other end of a backward switch 5b to a coil 15a of a backward relay 15. The other end of the acceleration pedal switch 11 is forked into a contact 13b of the forward relay 13 and into a contact 15b of the backward relay 15 and are thus connected therewith, while a contact 13c of the other side of the forward relay 13 and a contact 15c of the other side of the backward relay 15 are connected with the controller 7. A backward buzzer 9 is arranged between the backward switch 5b and the backward relay 15, and when the backward switch 5b is turned ON, the backward buzzer 9 is rung and an alarm signal is thus given.
