Function of Air Springs: Lift
The Lift mode is used to prevent control operations when a wheel is changed or during work on the vehicle while it is on a lifting platform.
LIFT MODE CODING PARAMETERS
| Coding parameter | Value |
|---|---|
| niv_lift_up | 60 mm |
| niv_lift_down | Unlimited |
| kerb_delay | <1s |
| time_ex_liftdetect | approximately 40 s |
| speed_lift_exit2 | 3 km/h |
This mode is detected when the permitted rebound travel at one or more wheels is exceeded > 55 mm. A jacking situation is also detected and the ride height stored if the lowering speed drops below the level of 2 mm/s for 1 second.
If the vehicle is raised only slightly and the permitted rebound travel has not yet been reached, the control operation attempts to readjust the ride height. If the vehicle is not lowered, a car jack situation is recognized after a specific period of time and this ride height is stored.
A reset is performed if the vehicle is again 10 mm below this stored ride height.
