Abstract
A skid steer vehicle has sprung suspensions, variable displacement pumps and motors connected to those pumps that drive the wheels on the vehicle as well as an electronic controller that receives signals that indicate fore-and-aft acceleration of the skid steer vehicle. Based on these signals, the controller determines whether the forward acceleration exceeds a predetermined value and locks up the rear suspensions if that value is exceeded. It also determines whether the forward deceleration exceeds a predetermined value and locks up the front suspensions if that value is exceeded. The signals can be provided by an accelerometer, a satellite receiver, wheel/motor speed sensors, sensors in the pumps that signal the specific displacement of the pumps such as their swash plate positions, or memory locations that contain previously calculated specific displacement commands that are used to drive the pumps to a particular specific displacement.
