Abstract
PURPOSE:To enhance the control accuracy of engine adjusting elements by deciding whether or not the (n+1) th detecting means, which is shown as the function of action characteristic amount in quantity (n), is normal and, in accordance with this decision result, controlling a study means while selectively using one of the two arithmetic means. CONSTITUTION:The first arithmetic means 58, which controls engine adjusting elements of an injector 8 and an ignition device 52 or the like being based on detection outputs of detecting means (throttle sensor 14, engine speed sensor 21, etc.) in quantity (n) and the (n+1) th detecting means (for instance, air flow sensor 11), is provided. While the second arithmetic means 62, which obtains a function relation of an action characteristic amount of each adjusting element by a study means 61 being based on an output of each sensor 14, 21, 11 to be stored in memory means 60A, 60B and calculates a control amount of these adjusting elements being based on the memory contents, is provided. Each adjusting element is controlled by selecting the first arithmetic means 58, when the air flow sensor 11 is decided to be normal in a decision means 63, while the second arithmetic means 62 when the air sensor 11 is decided to be abnormal.
