PURPOSE: An air dampness sensing method of an air suspension is provided to realize a monitoring logic sensing the compression state inside an air spring in real time, thereby alerting a driver to the serious air dampness state with a alerting lamp and enabling a driver to take a rapid A/S or predetected inspecting. CONSTITUTION: An air dampness sensing method of an air suspension is as follows. It determines whether car speed, steering angle and garage high is in state of satisfying the constant condition(S10). The pressure information within the spring corresponding to an air spring determines the state materialized by using LUT. If the garage change amount decreased below the set value as measuring the garage with each garage sensor installed in a car part, the garage height-A about sensed location is calculated(S33). It calculates pressure B and length C about an air spring with the garage height A calculation(S43). It compares the spring pressure B and the air spring length C about the garage height-A by using the data stored in LUT. It determines the air dampness about the state when measuring the air spring. |
