常停止装置。 Power is supplied from battery B, and a constant power supply voltage Vc is supplied to the control system for controlling the running of the work vehicle.
The engine emergency stop device for an automatic traveling vehicle is equipped with a constant voltage regulator 3 that supplies c and a means for activating a key stop relay RL 2 that forcibly stops an engine E. and a power down detection means A 1 for detecting an abnormal drop in the output voltage Vcc of the battery B, and a power down detection means A 1 for a predetermined period of time even after the power supply from the battery B is stopped.
When the power down detection means detects an abnormal decrease in the output voltage Vcc of the constant voltage regulator 3, the auxiliary power supply 4 supplies power to the keystroke relay RL. 2. An engine emergency stop device for an automatic traveling work vehicle configured to activate a means for activating.
