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 lateral acceleration of the skid steer vehicle during turns. The controller determines whether the lateral acceleration exceeds a predetermined value, and locks up the outboard 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 position, or memory locations that contain previously calculated specific displacement commands that are used to drive the pumps to a particular displacement.
