Abstract
A vehicle that has a drive train with an internal combustion engine, a transmission, and a number of ground engaging wheels. An operator-adjustable throttle control is monitored to provide a position signal corresponding to position of the throttle control. A sensor provides an observed speed signal corresponding to speed of the vehicle and a controller responds to the position signal and the observed speed signal to generate a target speed signal and an error signal. The target speed signal corresponds to a desired speed of the vehicle and is generated from a predetermined relationship between vehicle speed and throttle control position in accordance with the position signal. The error signal corresponds to a difference between the target speed signal and observed speed signal. The engine responds to the error signal to provide the desired vehicle speed for all operating speeds of the vehicle including a stopped or idle condition.
