Control lever calibration system
A control lever calibration system includes translating position signals of a control lever to traction drive motor commands for a work vehicle, determining if the position signals are within a stored range of control lever position signals, and expanding the stored range if position signals are outside the stored range.
1 . A control lever calibration system, comprising:
a control lever moveable in a work vehicle;
a neutral switch activated by the control lever in a neutral position;
an electronic sensor providing signals for the position of the control lever; and
an electronic controller saving the position signals of the electronic sensor when the neutral switch is activated; mapping the position signals of the electronic sensor to traction drive motor commands for the work vehicle; and saving the position signals of the electronic sensor each time the position signal exceeds a previously stored position range.
2 . The control lever calibration system of claim 1 , wherein the control lever is moveable on a first axis between a maximum position on a first end and a second end of the position range, and on a second axis to the neutral position.
3 . The control lever calibration system of claim 1 , wherein the control lever is configured to receive steering commands and the steering commands control a speed of the traction drive motor.
4 . The control lever calibration system of claim 2 , wherein the first end of the position range is a forward traction drive motor speed and the second end of the position range is a reverse traction drive motor speed.
5 . A control lever calibration system, comprising the steps of:
translating a plurality of position signals from a sensor for a control lever to a plurality of traction drive motor commands for a work vehicle;
determining if any of the plurality of position signals are within a stored range of position signals; and
expanding the stored range for any of the plurality of position signals that are outside the stored range.
6 . The control lever calibration system of claim 5 , further comprising the steps of:
detecting if the control lever actuates a neutral switch; and
storing the position signals for the control lever each time the neutral switch is actuated.
7 . The control lever calibration system of claim 6 , wherein the stored range of control lever position signals are based on rotational speeds of the traction drive motor.
8 . A control lever calibration system, comprising:
an electronic sensor that provides a plurality of position signals of a control lever for a work vehicle;
a controller that maps each of the plurality of position signals to a traction drive motor command for the work vehicle, saves each of the plurality of position signals for the control lever when a neutral switch is activated by the control lever, and saves each of the plurality of position signals that indicates a control lever position that is outside a previously stored range.
9 . The control lever calibration system of claim 8 wherein the work vehicle is a zero turn mower.
10 . The control lever calibration system of claim 8 wherein the control lever is a steering lever pivotable between a forward position and a reverse position.
