Abstract
An adaptive throttle controller for vehicle traction control is capable of adapting to changes in vehicle and engine parameters in order to compensate for uncertainties in vehicle parameters. The controller operates in a self-tuning mode by varying feedback gains online based on input/output relationships. The throttle controller system includes a wheel speed sensor for providing a first feedback variable related to wheel spin error, a traction controller for providing a second feedback variable related to throttle position, and a throttle control system responsive to the first and second feedback variable for controlling the throttle position to prevent wheel spin. The traction control method includes the steps of providing a wheel speed sensor for generating a first feedback variable related to wheel spin error, providing a traction controller for generating a second feedback variable related to throttle position, and providing a throttle control system responsive to the first and second feedback variables for controlling the throttle position to prevent wheel spin.
