|Title:||VEHICLE-MOUNTED DEVICE AND WARNING SYSTEM|
In a digital tachograph (10), a vehicle speed sensor (51) detects the speed of a vehicle. A fuel gauge (28) detects a fuel amount in a fuel tank (tk) mounted in the vehicle. A CPU (central processing unit) (11) allows a communication unit (24) to transmit a warning signal to the outside of the vehicle, when a speed indicating that the vehicle is stopped is detected and a fuel amount variation equal to or greater than a threshold value is detected.
