ABSTRACT:
A throttle valve control arrangement for an internal combustion engine comprising: a throttle valve; an electrical motor for actuating the throttle valve; mechanical links for coupling and decoupling the electrical motor with the throttle valve; a throttle position sensor for detecting a position of the throttle valve; and a control unit which compares an output signal from the throttle position sensor representing a detected throttle position with a signal representing a target throttle valve opening degree and generates a feed-back control signal for the electrical motor based on the comparison result, wherein the throttle position sensor shows a first output voltage characteristic with respect to throttle valve opening degrees for a first region covering ISC and FIC and a voltage gradient of the first output voltage characteristic is selected larger than that of an unmodified output voltage characteristic of the throttle position sensor, thereby a high resolution of the throttle position sensor is obtained for the first region.
