Throttle opening degree detecting device

Abstract

Abstract PURPOSE:To enhance the degree of accuracy for several kinds of controls in accordance with an opening degree which is properly detected, by performing compensation upon full closing of throttle valves so that the opening degree is determined by comparison in accordance with an absolute throttle relative opening degree and a true opening degree. CONSTITUTION:A first compensating means carrier out compensation for eliminating a deviation in output voltage upon full close of two throttle sensors so as to compensate an absolute opening degree detected by an opening degree detecting means, and thereafter, a second compensating means compensates the relationship between outputs from the two throttle sensors, corresponding to a difference between the opening degrees of two throttle valves. Accordingly, output voltages corresponding to the absolute opening degree and the relative opening degree which are identical with each other are compensated so as to have one and the same value. An opening degree selecting means compares the opening degrees of the two throttle valves with each other for the thus compensated absolute and relative opening degrees, and smaller one of them is selected as a detected throttle opening degree. With this arrangement, of two opening degrees of the throttle valves, the smaller one is properly selected, thereby it is possible to use its as a throttle opening degree.
