A method of adjusting an air suspension system comprises detecting with a positioning system that the vehicle is approaching a park location and reporting the park location is approaching to an electronic control unit for the air suspension system. A vehicle speed is determined and compared to a predetermined speed threshold, with the electronic control unit. The electronic control unit selects a park mode for the suspensions system when the vehicle is approaching the park location and when the vehicle speed is below the predetermined threshold. Air supply for the air suspension system is controlled to adjust the corner assemblies for the air suspension system to lowered positions associated with the park mode.

A method and apparatus of determining a straight-driving state or a turning state of a moving object using an acceleration sensor are provided. The method of determining a turning state using a sensor includes: reading sensor output signals of different axes from an acceleration sensor while a moving object is being driven wherein the acceleration sensor is an at least two axes acceleration sensor and detects an acceleration of the moving object; and comparing the read sensor output signals of the different axes and determining whether the moving object is in a straight-driving state or in a turning state.

A vehicle control device which can at least provide compatibility between a high grip performance and fuel efficiency or compatibility between quietness and fuel efficiency is provided. When a camber angle of a wheel 2 is adjusted to a negative camber, ground contact in a first tread 21 is increased and ground contact in a second tread 22 is decreased. Accordingly, the high grip performance or the quietness is provided. On the other hand, when the camber angle of the wheel 2 is adjusted to a positive camber, the ground contact in the first tread 21 is decreased and the ground contact in the second tread 22 is increased. Accordingly, a rolling resistance becomes low, and fuel saving is achieved. In this manner, by adjusting the camber angle of the wheel 2, the compatibility can be provided between conflicting performances of the high grip performance or the quietness and the fuel saving.
