Abstract: A device and method for selecting a control mode in a power construction vehicle is disclosed. The device has a control mode select switch which selects a function for setting new matching relations between the control levers and the proportional control valves. A controller sets the new matching relations and stores the new matching relations, and controls the actuators in accordance with the new matching relations. In the control mode selection method, one operational motion of an actuator is primarily selected and displayed on a display means. Thereafter, a voltage signal indicative of a levering angle of a control lever associated with the selected actuator is output, thus setting a new matching relation between the control lever and an associated proportional control valve. The above process is repeated in order to continuously set and store new matching relations between the control levers and proportional control valves associated with the other actuators.

Abstract: A method for detecting the direction and displacement of a rod member of a hydraulic cylinder assembly is provided. The hydraulic cylinder assembly includes a plurality of magnetic sensors for outputting a magnetic field variation signal disposed adjacent a hydraulic cylinder. The plurality of magnetic sensors cooperate with a plurality of magnetic projections equally spaced along a rod member for producing the magnetic field variation signal. The signal is converted from a sine wave into a square wave by using a microprocessor. The edges of the converted square wave are counted to accurately detect a direction and displacement amount. The method further includes the steps of ignoring a square wave edge caused by disturbance, if the square wave edge occurs prior to a pre-set time, wherein the pre-set time is based on the average time interval for previous edges. The method further includes the step of generating a correction edge when no edge is detected during the pre-set time interval. The method still further includes the step of detecting successive correction edges for determining an absolute position of the hydraulic stroke.

Abstract: A control device for a travelling system in construction vehicles is disclosed. The control device applies the pilot pressure of the pilot pump to the spool of the directional control valve separately from the travelling control pedal, thus automatically controlling operation of the directional control valve. However, the manual control mode performed by the travelling control pedals has priority over the automatic control mode. The control device has a proportional control valve, which applies the pilot pressure of the pilot pump to the spool in response to an input current signal. A pressure sensor checks the pilot pressures, which are generated by both the travelling control pedals and the proportional control valves and act on the spool. A controller receives a signal indicative of the pilot pressures checked by the pressure sensor and outputs the current signal to the proportional control valve.

Abstract: A device and method for automatically vibrating the working members of a power construction vehicle such as a power excavator is disclosed. The device and method effectively change both the amplitude of vibration and the number of vibrations of a working member in proportion to a levering angle of an associated control lever during an excavating, breaking or ground hardening operation of a construction vehicle. The automatic vibration device is thus free from any select switch. The device simplifies the construction of the hydraulic system and more easily controls the automatic vibration operations, and thereby is convenient to operators.
