Abstract

A calibration procedure involves the steps of manually placing a throttle handle in five preselected positions that correspond with mechanical detents of the throttle control mechanism. At each of the five positions, one or more position indicating signals are received by a microprocessor of a controller and stored for future use. The five positions comprise wide open throttle in forward gear, wide open throttle in reverse gear, the shift position between neutral and forward gear, the shift position between neutral and reverse gear, and the mid-point of the neutral gear selection range. The present invention then continuously monitors signals provided by a sensor of the throttle control mechanism and mathematically determines the precise position of the throttle handle as a function of the stored position indicating signals. In one embodiment, each position indicating signal comprises three redundant signal magnitudes.
