Abstract
An illustrative embodiment of a fuel injector control system includes a driver that is configured to supply electrical power to a fuel injector. A controller is configured to control the driver according to a predetermined sequence of states for an injection cycle. The plurality of predefined states each include parameters for supplying electrical power to a fuel injector. Each of the states has a corresponding plurality of test parameters. At least one of the test parameters is a target parameter for the state. During each of the states, the controller determines whether at least one of the test parameters is met and determines how to control the driver for a subsequent portion of the injection cycle based on which of the test parameters is met.
