    摘要： A ground engaging vehicle having a tool connected to the vehicle, at least one actuator coupled to the tool and an electronic controller. The electronic controller is controllably coupled to the at least one actuator. The controller includes an operator interface. The controller is configured for issuing a plurality of commands, recording the commands, positioning the tool and replaying at least some of the commands. The issuing step includes issuing a plurality of commands to the at least one actuator using the operator interface to place the tool in a position relative to the vehicle. The recording step records the commands issued in the issuing step. The positioning step includes positioning the tool in another position different from the position. The replaying step includes replaying at least some of the commands recorded in the recording step, thereby repositioning the tool substantially in the original position.

    摘要： A hydraulic control system in which a pump for pressurized hydraulic fluid connects with a valve assembly having a valve element displaceable in a chamber to selectively direct fluid to a load driven by the hydraulic system. Surfaces on the end faces of the valve element are exposed to hydraulic pressure from a controller via electro-hydraulic solenoid valves. The surfaces of the valve element adjacent the end faces are undercut to establish a leakage flow path and the solenoid valves are selectively actuated to pressurize the end faces to a level below normal actuation of the valve element but high enough to cause fluid to return to a drain and thus increase the temperature of the hydraulic fluid in the system.

    摘要： A vehicle and drive system control method for a vehicle including first and second traction elements coupled to the vehicle, a variable displacement pump, a bi-directional variable displacement first motor coupled to the first traction element, and a bi-directional second motor coupled to the second traction element. The pump, and first and second motors are coupled fluidly in series with one another. A control unit can determine a desired speed for the traction elements, and determine pump, first and/or second motor displacements based on the desired speed. First and second speed sensors can sense output speeds of the motors, and the pump, first and/or second motor displacements can be determined based on the motor output speeds. Articulation and steering sensor signals can also be used to determine pump, first and/or second motor displacements.
