摘要： A calibration system for use on a work machine wherein electro hydraulic controls are utilized to control the operation of a particular work element, the present calibration system being operable in both a semi-automatic mode and an automatic mode. In the semi-automatic mode, operator interaction is required and the calibration process is preferably initialized and controlled via a service tool which is in communication with a work machine controller. A command signal having a command signal value indicative of a command state of the component being calibrated is generated by a command signal generator, and a detector in communication with the component receives the component signal and detects when the component has reached the command state, and generates a detector signal having a value representing a calibration factor to be used in correlating the component signal value with the actual state of the component. In the automatic mode, no operator interaction is required and the controller automatically and dynamically correlates and compares the current state of the particular component being calibrated with its last stored state and thereafter calibrates the component upon detecting a difference therebetween.

摘要： A control system regulated the tilt of an implement of an earlier working machine. Fluid operated lift and tilt cylinders are connected to the implement. Hydraulic control valves deliver pressurized hydraulic fluid to the lift and tilt cylinders. A control lever produces an implement tilt command signal in response to position of the control lever. A controller receives the implement tilt command signal and responsively delivers an implement tilt control signal to the hydraulic valves to cause pressurized fluid flow to actuate at least one of the lift and tilt cylinders to tilt the implement. First and second displacement sensors produce first and second position signals indicative of the extension of the respective lift cylinders. The controller receives the first and second position signals, determines a magnitude of the difference between the relative positions of the first and second lift cylinders, compares the magnitude difference to a maximum differential value, and stops the delivery of the implement tilt control signal in response to the magnitude difference being substantially equal to the maximum differential value.

摘要： A blade control system includes a directional control valve, a fluid regeneration valve and a selector valve for selectively controlling fluid flow between a pump and first and second hydraulic cylinders and between the cylinders. With the valves positioned at preselected operative positions, pressurized fluid from the pump is directed to the head end chamber of the first cylinder, fluid expelled from the rod end chamber of the first cylinder is diverted to the head end chamber of the second cylinder, and fluid expelled from the rod end chamber of the second cylinder is combined with the fluid being directed to the head end chamber of the first cylinders to provide two stages of fluid regeneration for increasing the extension speed of the cylinder.
