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.
