ABSTRACT:
A device and a method to detect dynamic changes in the level or ground clearance of a vehicle. The changes are determined indirectly by the instances of longitudinal acceleration of the vehicle which are analogous with these changes, preferably by calculation from signals of rotational speed sensors for the vehicle wheels. Such sensors are normally present in vehicles with anti-lock braking system or traction control systems.
