    Abstract: A suspension system having a frame, a cab having a front portion pivotally mounted to the frame and at least one actuator mounted between a rear portion of the cab and the frame. A position sensor is mounted adjacent the rear portion of the cab for generating a first signal indicating a position of the cab relative to the frame, an accelerometer is mounted to the frame for generating a second signal indicating an acceleration of the frame relative to gravity and an electronic control receives the first and second signals from the position sensor and the accelerometer and generates a control signal for controlling the actuator in response to the first and second signals.
