Patent ID: 8387378

Claim:
A hydraulic system for a mobile machine having an implement, the hydraulic system comprising: a hydraulic actuator configured to move the implement; a storage device configured to store pressurized fluid; a valve operable to fluidly communicate the storage device with the hydraulic actuator; a sensor associated with the mobile machine to generate a signal indicative of a speed of the mobile machine; and a controller in communication with the valve and the sensor, the controller being configured to: determine when the speed is associated with a forward or reverse travel direction of the mobile machine based on signals received from the sensor; compare the speed of the mobile machine to a setpoint; determine an amount of time elapsed during which the speed of the mobile machine exceeds the setpoint; and selectively operate the valve to fluidly communicate the storage device with the hydraulic actuator based on the elapsed amount of time, the travel direction, and the speed to cushion movement of the implement.
