<p>PROBLEM TO BE SOLVED: To surely and quickly grasp apprehension of cargo collapse in a trailer without providing an expensive detection sensor in the trailer. SOLUTION: By a trailer gravitational center position arithmetic means 16, based on an engine speed of a tractor, governor angle or accelerator throttle valve opening, wheel speed of the tractor, air suspension pressure, tractor mass, and a position of the center of gravity of the tractor, during operation of a tractor trailer, engine drive force, vehicle acceleration, trailer mass, and a position of the center of gravity of the trailer are calculated. By a gravitational position comparing means 17, a calculated trailer gravitational center position is compared with a reference value, when a difference between these values is a prescribed value or more, apprehension of collapse of a trailer loaded cargo is decided, an alarm means 10 is operated, to generate an alarm.</p> |
