    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.

    Abstract: A hydraulic implement system for a machine is disclosed. The hydraulic implement system may have a boom member, a boom actuator, and a boom operator control device movable to indicate a related operator desired boom member velocity. The hydraulic implement system may also have an implement pivotally connected to the boom member, an implement actuator, and an implement operator control device movable to indicated a related operator desired implement velocity. The range of the implement operator control device may be divided into a first portion and a second portion. The hydraulic implement system may also have a controller configured to selectively limit a velocity of the implement during manipulation of the implement operator control device within the first portion such that a lift velocity of the boom member of at least 65% of the desired boom member velocity is always possible.

    Abstract: Apparatus and methods are provided for controlling a double-acting hydraulic cylinder during a load-induced rod-extending operation. The apparatus includes a activation circuit and valve for providing a flow path from a pump to the cylinder head end; a flow regeneration circuit and valve fluidly connecting the cylinder rod end and the cylinder head end and configured for providing flow from the rod end to the head end during rod extension; and a controller responsive to rod-extending rate demands and rod-position sensor signals, and operatively connected to the regeneration flow valve and the activation valve. The activation valve also includes a return valve part to control flow from the rod end to the fluid reservoir during rod extension. Both the activation valve and the return valve part are controllable by the controller independently from the regeneration flow valve.
