PURPOSE:To prevent overrun of the vehicle, by stopping the engine of the viehicle or making it idle when the operation board is caused to fall down or a strong shock is given to it. CONSTITUTION:The pulse signal from two channels of the running system and the working system which are not shown in the figure is applied to mixer curcuit 7, and mixer circuit 7 transmits the mixed output to FM transmitter 8 through switch 25 to perform the radio control of the vehicle. Sensor 21 of safety device 20 is constituted with, for example, a mercury switch and is turned on when a strong shock is given to the operation board or the operation board is inclined at a certain angle or more. The output turns on latch circuit 22 and opens switch 25 to stop tranmission from the FM transmitter, thereby stopping the vehicle. For resetting, horn switch SWH is operated to turn off latch circuit 22 after making the operation board horizontal. |
