Title:
METHOD FOR ADAPTING A FUEL INJECTOR CONTROL SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/081835
Kind Code:
A3
Abstract:
The invention relates to a method for adapting a control signal of a control circuit of at least one injector of a motor vehicle combustion engine, said control signal being a square-wave voltage signal having a frequency that can vary between a minimum frequency and a maximum frequency, characterised over a given period by its duty cycle. For a given period of the control signal, the method comprises, in particular, the steps of: determining the start time of the given period; detecting (E1) the first pulse of the given period after the start time; and, when the duration of the first detected pulse is within a minimum time interval starting from the start of the given period, said duration being a function of the maximum frequency, modifying (E5) the duration of the first detected pulse such that the duration is equal to the duration of the minimum time interval.
