摘要： An engine control module (ECM) having a plurality of driver banks is provided. Each of the driver banks is configured to drive a plurality of combustion control elements. The driver banks include two low side driver circuits and a high side driver circuit, the high side driver circuit in each of the plurality of driver banks being shared pairwise by two combustion control elements. Each one of said at least two low side driver circuits is respectively associated with the two combustion control elements. The ECM includes a field programmable gate array (FPGA) coupled to the plurality of driver banks and configured to provide firing signals to at least twelve high side driver circuits to simultaneously drive at least twelve combustion control elements respectively coupled to the at least twelve high side driver circuits.

摘要： A method of detecting a resistive short-to-ground fault in an injector driver circuit is disclosed. The method includes determining if the injector driver circuit is in an inactive state and providing a pull-up resistor configured for connection to a low-side output of at least one fuel injector. The method further includes selectively enabling a pull-up voltage across the pull-up resistor only when the injector driver circuit is in the inactive state and determining an intersection voltage at a point between the pull-up resistor and the low-side output. The method further includes comparing the intersection voltage with a predetermined reference voltage. The method further includes disabling the injector driver circuit if the short-to-ground fault is detected at the low-side of the fuel injectors.
