HEIGHT ADJUSTMENT IN A VEHICLE FITTED WITH AIR SUSPENSION

摘要

A height sensor (20) of a height regulating device of an air spring suspension system of a vehicle is calibrated by using the air spring bellows (16) as jacks while the height regulation by the control device (44) is disabled. A dialog is set up between a test device (50) connected by an interface (52) with the control device (44), whereby the test device (50) takes over the control of the air supply to and from the air spring bellows (16) and the height of the vehicle body (10) is brought to a desired null height. The output (hn) of the sensor (20) is then stored in a non-volatile memory and is used as a reference height (ho) for the height regulation.
