Abstract
A process for preventing overturning of a utility vehicle equipped with an ABS or EBS braking system comprises:(a) detecting the load on two corresponding wheels on each side of the vehicle;(b) when the vehicle is traveling in a curve to the left or right, determining the lateral acceleration of the vehicle;(c) simultaneously determining the change in load value for the inner of the two corresponding wheels at that lateral acceleration value;(d) repeating steps (b) and (c) for a curve in the other direction;(e) from the lateral acceleration value and the associated changes in load values, determining and storing limit acceleration values for curves to the left and to the right, which limit acceleration values represent the lateral acceleration of the vehicle as it travels in a curve to the left or to the right which result in no load on an inner wheel of the vehicle;(f) continuously monitoring the lateral acceleration the vehicle; and(g) when the lateral acceleration of vehicle as it travels in a curve to the left or to the right reaches a predetermined percentage (e.g., 70-80%) of the limit acceleration value for a curve in that direction, emitting a signal which causes the vehicl…
