Title: Engine speed measuring device for internal combustion engine
Inventor: MATSUMOTO KENJI
IPC: F02D45/00
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To detect noise correctly without wrong detection by using a sensor with output signal pulse width angularly constant, as a rotation sensor, and comparing the pulse width measured by a measuring means with the pulse width estimated by an estimating means to judge whether the measured pulse is noise or not. SOLUTION: In case of starting with the rising edge of a rotation sensor signal as a trigger and measuring rotation pulse width, the rising edge time T1 of the present rotation sensor signal is latched, and then the falling edge time T2 is latched in a step S12. In a step S13, T2-T1 is computed to compute the present pulse width measured value P, and then the pulse width estimate P' is computed in a step S14. In a step 15, the measured value P and the estimate P' are compared, and in the case of satisfying (P' - specified value) < P < (P' + specified value), it is judged to be a normal rotation pulse signal. In the case of not satisfying, it is judged to be noise. The normal rotation pulse signal is used for control timing pulse.
