Title:
FUEL INJECTION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/191730
Kind Code:
A1
Abstract:
This fuel injection control device includes a correction unit (21) which uses a valve closing timing detected using a timing detection method, to calculate a correction coefficient for correcting a valve closing timing detected using an electromotive force amount detection method. In cases when an electromotive force detection method is selected by a selection unit (21), and the valve closing timing is detected using the electromotive force amount detection method, an estimation unit (21) estimates an estimated injection amount using the valve closing timing which has been corrected using the correction coefficient.
