摘要： A control system and method for detecting and inhibiting an impending full saturation condition in a hydraulic system of a work machine wherein the hydraulic system includes a hydraulic pump for supplying fluid under pressure to the hydraulic system and a plurality of control valves for controllably passing fluid from the pump to a plurality of work elements, the present control system including an electronic controller coupled to both an operator input device actuatable to control the operation of the work elements and a plurality of control valves for controlling the fluid flow to the work elements, the controller being operable to determine the actual margin pressure of the hydraulic pump in response to comparing the pump pressure to the pressure of the heaviest loaded work element requested by an operator through the actuation of the operator input device and to compare the actual margin pressure to the established margin pressure for the pump. Based upon this comparison, the controller is further operable to output appropriate signals to the control valves to limit fluid flow thereto in accordance with some type of valve prioritization scheme when the actual margin pressure of the pump is less than the established margin pressure. The present control system and method functions as an early warning system to both detect the onset of an impending full saturation condition and to implement appropriate procedures to inhibit further saturation and limit any resultant valve starvation.

摘要： An interlock control system for controlling certain operations of a work machine wherein such system includes a first switch coupled to an operator restraint mechanism, a second switch coupled to the operator seat, a third switch operable to control the operation of the parking brake mechanism, and an electronic controller coupled to all three switches for receiving signals therefrom, the controller outputting a signal to enable the drive mechanism and the implement control system when the controller receives signals from the first, second and third switches indicative of the fact that the operator is present in the seat, the operator restraint mechanism is positioned in its restraining position, and the parking brake switch has been actuated to release the parking brake. With the drive mechanism and implement control system enabled, a second activation of the parking brake switch will disable the drive mechanism and set the parking brake, but it will not disable the implement control system. In addition, regardless of the particular operating mode, as soon as the interlock controller senses that either the operator restraint mechanism has been moved out of its restraining position and/or the operator is no longer present in the seat, the controller will disable the drive mechanism and the implement control system, and it will apply the parking brake.

摘要： The present invention provides a ride control 100 for a machine having an implement and a hydraulic lift cylinder. The hydraulic lift cylinder is adapted for moving the implement to and between a plurality of positions. The ride control is controllable between a RIDE CONTROL ON mode, a RIDE CONTROL OFF mode and a RIDE CONTROL PROGRAM mode. In the RIDE CONTROL ON mode, the ride control connects and disconnects an accumulator from the hydraulic lift cylinder circuit as a function of machine velocity. In the RIDE CONTROL OFF mode, the ride control disconnects the accumulator from the hydraulic lift cylinder circuit. In the RIDE CONTROL PROGRAM mode, the ride control sets the threshold for activation of the ride control to the current machine velocity.
