Method for the avoidance of rollover phenomena in semitrailers
First Claim
1. A method for the avoidance of rollover phenomena in a semitrailer with the emission of warning signals for a driver of said semitrailer when driving inappropriately, wherein a center of gravity of a load of the semitrailer is calculated in an on-board computer and, from said center of gravity, thus determined, and a known weight of said semitrailer, said on-board computer calculates a rollover limit as a function of instantaneous driving parameters, on exceeding of which limit a warning is issued to said driver of said semitrailer, wherein a steering angle and a road speed are continuously determined by methods of measurement, and, in said on-board computer, said steering angle and said road speed are compared with said rollover limit determined as maximum admissible road speed for said steering angle.

Abstract
In a method for the avoidance of rollover phenomena in semitrailers with the emission of warning signals for the driver of the vehicle when driving inappropriately, the center of gravity of the load of the semitrailer is calculated in an on-board computer. From the center of gravity thus determined and the known weight of the loaded semitrailer, the on-board computer calculates a rollover limit as a function of instantaneous driving parameters, on exceeding of which limit a warning is issued to the driver of the vehicle.
