1. A process for preventing overturning of a vehicle having a plurality of axles and equipped with an ABS or an EBS braking system, said vehicle having at least one wheel on each side of said vehicle mounted on each of said axles, said method comprising:

  • (a) detecting the load on corresponding wheels on each side of said vehicle, (b) determining a lateral acceleration value of said vehicle as it travels in a curve to the left or to the right, (c) simultaneously determining a change in load value for the inner one of said corresponding wheels for said lateral acceleration value, (d) repeating steps (b) and (c) for said lateral acceleration value as said vehicle travels in a curve in the opposite direction, (e) from said lateral acceleration value and the determined change in load values for curves to the left and right, determining and storing a limit acceleration value for a curve to the left and for a curve to the right which limit acceleration value represents the lateral acceleration of said vehicle when it travels in a curve resulting in no load on the inner one of said corresponding wheels;

    (f) continuously monitoring the lateral acceleration of the vehicle; and

    (g) when the lateral acceleration of the vehicle as it travels in a curve to the left or right reaches a predetermined percentage of the limit acceleration value for a curve in that direction, emitting a signal which causes the vehicle to slow down.
