Patent ID: 6895319

Claim:
In a system having a hydraulic function which can be extended and retracted under the control of an electrohydraulic valve unit, an operator movable command lever movable into extend, center and retract regions, a sensor generating a lever position signal, an electronic lever command unit receiving the lever position signal and generating a valve command signal, an electronic valve control unit (VCU) remote from and communicated with the lever command unit, the VCU supplying hydraulic fluid to the hydraulic function in response to the valve command signal, a method of generating the valve command signal comprising: determining a movement oscillation frequency of the lever; and if the oscillation frequency is greater than a threshold value, transmitting to the VCU a maximum extend command derived from maximum lever position values when the lever is in the extend region, and transmitting to the VCU a maximum retract command derived from maximum lever position values when the lever is in the retract region.
