摘要： A throttle full-closure detecting apparatus for judging the full-closure state of a throttle valve uses the minimum value of a throttle sensor voltage so that the apparatus output is compensated for, in particular, a change in temperature. In a timer routine in the apparatus, first, the throttle sensor output is AD-converted and the thus AD-converted output is stored into a RAM and a general purpose register Ar. Next, a full-closure angle is stored in a compare register Cr and the contents of Ar and Cr are compared with each other so that when Cr>Ar, the AD-converted throttle value is stored as a full-closure angle and first storage updating is performed with the minimum throttle opening as the angle. Further, second updating for adding a specified value to the stored value of the full-closure angle is performed at a period sufficiently larger than the period of the time routine, and the first updating is made ready after the second updating.

摘要： In an ignition control system for the internal combustion engine, a reference angle sensor detects the rotational speed of the internal combustion engine, and detects a point near the top dead center, and generates a reference angle signal. An angle sensor similarly detects the rotational speed of the internal combustion engine, and discriminats the rotational speed for each predetermined angle, and generates an angle signal. A microcomputer includes an output compare register, a free-running counter and a timer control status register, and computes the ignition timing and energization time of the ignition coil in response to a reference angle signal from the reference angle sensor and an angle signal from the angle sensor.
