Title
(EN) CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE
Abstract
(EN)

An internal combustion engine control apparatus includes an output-current abnormality-signal holding unit (112) that determines whether a current abnormality signal is being output from a current-abnormality detecting unit (108, 110), which compares a current value detected by a current detecting unit (R1, R2) with a predetermined threshold, and outputs a current abnormality signal when the current value is equal to or less than the predetermined threshold continuously for a predetermined time or longer, and outputs a current abnormality signal when the current abnormality signal is being output continuously for a predetermined time or longer, and does not output a current abnormality signal when the current abnormality signal is output continuously for less than the predetermined time.
