Claim Text:
1. A fuel control system for a vehicle, comprising: a voltage measuring module that measures first and second voltages at first and second electrical connectors of a fuel injector of an engine; a first summer module that determines a first sum of (i) a difference between the first and second voltages and (ii) N previous values of the difference between the first and second voltages, wherein N is an integer greater than or equal to one; a second summer module that determines a second sum of (i) the first sum and (ii) M previous values of the first sum, wherein M is an integer greater than or equal to one; a first difference module that determines a first difference based on the second sum; a second difference module that determines a second difference between (i) the first difference and (ii) a previous value of the first difference; and an injector driver module that selectively applies power to the fuel injector based on the second difference.
