Document Type and Number:
WIPO Patent Application WO/2017/191728
Kind Code:
A1
Abstract:
This fuel injection control device includes: a valve closing detection unit (54) which uses one detection method from among an electromotive force amount detection method and a timing detection method to detect a valve closing timing; and a selection unit (21) which selects which of the detection methods among the electromotive force amount detection method and the timing detection method is to be used to detect the valve closing timing. The selection unit selects the timing detection method if a requested injection amount is greater than a prescribed reference injection amount for partial lift injection, and selects the electromotive force amount detection method if the requested injection amount is smaller than the reference injection amount.
