Vehicle suspension systems

摘要

A ride-height adjustment system (100) for a vehicle (10) comprises its suspension system, which is adjustable to change the ride height of a vehicle in which it is fitted. The system has a first means, to detect a preliminary end-of-journey (EOJ) event, such as seat belt unbuckling or ignition switch-off. A controller adjusts the suspension system in a first movement in response to detection of said preliminary EOJ event, to change the ride height of the vehicle towards an access ride height of the vehicle. The access ride height is a predetermined ride height that facilitates egress from and entrance to the vehicle. Second means detect opening of a door of the vehicle. When the ride height of the vehicle remains different from the access ride height after said first movement, the controller is adapted to further adjust the suspension system in a second movement in response to said door-opening detection. This further changes the ride height of the vehicle towards said access ride height of the vehicle.
