PURPOSE:To prevent upset of a vehicle by comparing the output of an inclinometer on the vehicle with a pre-memorized output which corresponds to the upset angle for the vehicle and generating a signal which indicates the safety degree corresponding to the comparison output. CONSTITUTION:The difference theta' between the output theta of an inclinometer 9 and a set point A is compared with the output thetao of a memory unit 12a, and the value thetao-theta' is fed to a meter 14al for display and to comparators 14a2 and 14a3. The comparators 14a2 and 14a3 compare the value thetao-theta' with the values V1 and V2 corresponding respectively to the boundary value between a sefety range and a contion range and to the boundary value between the caution range and a danger range. When the value thetao-theta' is in the caution range, an output is fed from an exclusive ''or'' circuit 14a4 to a lamp 14a7 and a buzzer 14a9 so as to make a ''caution'' alarm. When the value thetao-theta' is in the danger range, a similar output is fed to a lamp 14a8 and a buzzer 14a10 so as to make a ''danger'' alarm. Thus check of safety degree by an operator is enabled and the upset can be prevented. |
