Abstract
A speed controller maintains the engine throttle at a desired throttle position based upon an initial throttle position and a speed error signal. The initial throttle position is generated by multiplying vehicle speed by a constant and adding an offset value related to throttle position at idle and speed control slack. The initial throttle position is adaptively updated by subtracting the above product from actual throttle position during speed control operation to learn a new offset value.
