Electronic engine power control system for a motor vehicle

An electronic engine power control system for a motor vehicle, the system comprising:

• an open-loop and closed-loop control arrangement;
• an electrically actuable actuating element movable within a pregiven first range for influencing the power developed by the engine;
• first measuring means connected to said actuating element for providing a signal indicative of the position of said actuating element;
• an operator-controlled element operable by a driver of the vehicle and movable within a pregiven second range;
• second measuring means connected to said operator-controlled element for providing a signal indicative of the position of said operator-controlled element;
• at least one of said measuring means being configured to apportion the range corresponding thereto into a first measuring range corresponding to positions of said element which are at or near idle wherein said measuring means emits a first signal of first resolution indicative of the position of the element within said first measuring range and a second measuring range wherein said measuring means emits a second signal of a second resolution indicative of the position of the element within said second measuring range with said first resolution being greater than said second resolution;
• said control arrangement including:
• a desired-value forming unit for providing a pregiven desired-value signal indicative of the desired value of the position of said actuating element;
• said desired-value forming unit being connected to said second measuring means for receiving said signal indicative of the position of said operator-controlled element;
• a controller for comparing said desired-value signal to said first signal for controlling said actuating element to a position corresponding to the position represented by said desired-value signal;
• and,
• said controller being adapted to adjust the position of said actuating element outside of the idle condition of the engine at least in dependence upon a pregiven value derived from the position of the operator-controlled element.
