Abstract
A method is for monitoring the wear of an air suspension for motor vehicles. A filling volume of a spring bellows determines a level position of an air spring and the level position is continuously detected by a height sensor. The level position detected by the height sensor is compared with a predetermined upper level position value for a high level position and a predetermined lower level position value for a low level position. Instances of level attainment, when the detected level position exceeds the upper level position value or the detected level position falls below the lower level position value are counted. From the count of the instances of level attainment, a wear status of the air suspension is concluded.
Claims6
A method for monitoring wear of an air suspension for motor vehicles, the method comprising:
- continuously detecting a level position of the air suspension via a height sensor, wherein a filling volume of a spring bellows determines the level position of the air suspension;
- comparing the level position detected by the height sensor with a predetermined upper level position value for a high level position and a predetermined lower level position value for a low level position;
- counting instances of level attainment if the detected level position exceeds the upper level position value or the detected level position falls below the lower level position value;
- and,
- determining a wear status of the air suspension from the count of the instances of level attainment.
