Abstract

An electronic engine power control system is disclosed for a motor vehicle wherein a measuring arrangement is utilized for determining the position of an actuating element. The measuring arrangement is configured in such a manner that it has different resolutions in various ranges of the position of the actuating element. The open-loop or closed-loop control of the position of the engine power-determining element or of the actuating element in idle or near idle is undertaken in dependence upon the measurement signal of high resolution while, outside of the idle or near idle range, the control of the actuating element is undertaken in dependence upon measurement signals of low resolution or a straight open-loop control of the position of the actuating element.
