Abstract
A method and system for controlling a vehicle suspension system switchable between two modes of operation, including a first mode for when the vehicle is experiencing an on-road driving condition and a second mode for when the vehicle is experiencing an off-road driving condition, includes a vehicle speed sensor for sensing a speed of the vehicle and generating a vehicle speed signal, which may be an inherent part of the vehicle required for other vehicle functions, such as ABS, speed, or other control. The system also includes a controller for detecting an off-road driving condition and comparing the vehicle speed signal to a predetermined speed threshold. The controller then controls the suspension system to switch to the second mode of operation upon detecting the off-road driving condition and the vehicle speed signal being less than the predetermined speed threshold.
