Abstract

A method for monitoring and controlling a chassis pneumatic ride-height control system. Repeatedly measuring a current height of the chassis; detecting when the current height of the chassis exceeds at least one predefined height threshold. A time interval threshold is associated with the height threshold; repeatedly measuring a time interval in which the current height of the chassis exceeds the predefined height threshold; detecting when the measured lime interval exceeds the predefined time interval threshold associated with the predefined height threshold; repeatedly checking whether both the height threshold and the associated time interval threshold are exceeded, and if so, preventing the current height of the chassis from rising further and/or increasing stability of the chassis; deactivating the measures when the repeated check shows that the current height of the chassis is below the at least one height threshold and the associated time interval threshold.
