METHOD AND MEANS FOR SELF CALIBRATING A VALID OPERATING RANGE
A method of calibrating a valid operating range. The method includes loading a default calibration limit and then monitoring an input for new calibration limits provided by an input device. An algorithm then detects if the new calibration limits provide a fault and if not the algorithm rescales the output based upon the new calibration limits to increase the valid operating range.
1 . A method of calibrating a valid operating range steps comprising:
loading default calibration limits;
monitoring inputs for new calibration limits from an input;
detecting if the new calibration limits provide a fault; and
resealing outputs with an algorithm based upon the new calibration limits to increase the valid operating range.
2 . The calibrating method of claim 1 further comprising the step of retaining a last valid output when a fault is detected.
3 . The calibrating method of claim 1 wherein when a fault is detected for a predetermined amount of time a fault timer returns the input to a neutral position.
4 . The calibrating method of claim 3 wherein when the input is returned to the neutral position the default calibration limits are reloaded.
5 . The calibrating method of claim 1 wherein the new calibration limits are based upon voltages.
6 . The calibrating method of claim 1 wherein the new calibration limits are based upon currents.
7 . The calibrating method of claim 1 wherein the default calibration limits are for a joystick of a backhoe.
