Patent ID: 8899143

Claim:
A hydraulic control system, comprising: a pump configured to pressurize fluid; an actuator; a position sensor associated with the actuator and configured to generate a first signal indicative of a position of the actuator; a circuit fluidly connecting the pump to the actuator; a valve associated with the circuit and configured to move from a first position at which fluid relief from the circuit through the valve is inhibited, toward a second position at which fluid is relieved from the circuit through the valve, when a pressure of fluid within the circuit exceeds a threshold setting of the valve; a controller in communication with the position sensor and the valve, the controller being configured to selectively adjust the threshold setting of the valve based on the first signal; and an operator input device movable from a neutral position toward a maximum displaced position to generate a second signal indicative of a desired actuator movement, wherein the controller is further configured to increase the threshold setting to a maximum pressure when the operator input device is returned to the neutral position.
