Title: Control device for internal combustion engine
Inventor: SHIRAISHI TAKASHI
IPC: F02P5/15
Filed: 1991-11-20
Abstract: PURPOSE:To accurately seize a noise generating timing at a starter starting time and at a stopping time by limiting a noise generating period by means of a starter starting signal, and carrying out treatment to a sensor signal. CONSTITUTION:In a reference position signal 202 of which a cylinder discriminating signal 201 generated from a cylinder discriminating sensor is generated from a magnetic sensor, both sensor signals 201 and 202 are inputted to a gate array 403 after passing through waveform shaping circuits 401 and 402. A starter signal 405 is also inputted to a microcomputer 404. While using the starter signal 405 as a noise generating period detecting signal, the sensor signals 201 and 202 are detected for the first time as normal signals after a prescribed period immediately after a starter is started. By changing a filter constant to sensors for a prescribed period after the starter starting is finished, a turbulence of a signal waveform caused by noise can be prevented. Thereby, a noise generating timing at a starter starting time and at a stopping time can be seized accurately.
