Abstract
An apparatus and method for providing a detent function on a hydraulic system. The hydraulic system includes a hydraulic implement movable between first and second implement positions. The apparatus and method receives a control input signal generated by an electronic control handle in response to operator input, monitors the control input signal, and actives a detent function if the control input signal follows a preset pattern. The preset pattern includes moving the handle to a detent area, between first and second positions, and then back to neutral, within a given time period. There is also a force feedback to the handle, opposing operator movement; which is proportional to the distance moved from neutral, and which has different attributes within and outside the detect area.
