Title:
FUEL INJECTION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/191729
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; 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; and a correction unit (21) which calculates a correction coefficient for correcting a requested injection amount such that the difference between an estimated injection amount and the requested injection amount is reduced. If the calculation of the correction coefficient is incomplete, the selection unit selects the electromotive force amount detection method regardless of the value of the requested injection amount.
