Method for monitoring and controlling a pneumatic ride-height control system of a chassis system

摘要

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.

1. A method for monitoring and controlling a pneumatic ride height control system of a chassis system, wherein the method comprises the steps:
repeatedly measuring, by sensors, a current ride height of the chassis system, detecting, by a processor, when a first predefined ride height threshold value is exceeded by the current ride height of the chassis system, detecting, by the processor, when a second predefined ride height threshold value, which is greater than the first threshold value, is exceeded by the current ride height of the chassis system, wherein a first time interval threshold value is associated with the first ride height threshold value and a second time interval threshold value is associated with the second ride height threshold value, repeatedly measuring, by the processor, a time interval in which the current ride height of the chassis system exceeds at least one of the first predefined ride height threshold value and the second predefined ride height threshold value, detecting, by the processor, when the first predefined time interval threshold value associated with the first predefined ride height threshold value is exceeded by the measured time interval, detecting, by the processor, when the second ride height threshold value is exceeded by the measured time interval, repeatedly checking, by the processor:
whether both the first ride height threshold value and the associated first time interval threshold value are exceeded, and when both the first ride height threshold value and the associated first time interval threshold value are exceeded, automatically activating a first predefined technical measure that is suitable for at least one of preventing further raising of the current ride height of the chassis system and for increasing a stability of the chassis system, andwhether the second ride height threshold value and the associated second time interval threshold value are exceeded, and when the second ride height threshold value and the associated second time interval threshold value are exceeded, automatically activating a second predefined technical measure that is suitable for at least one of preventing further raising of the current ride height of the chassis system and for increasing the stability of the chassis system, deactivating, by the processor, the automatically activated measures when the repeated checking, by the processor, reveals that the current ride height of the chassis system is below the first ride height threshold value minus a hysteresis and beyond an associated time interval threshold value.
