    摘要: An engine system includes a status determination module and an open-loop fuel control module. The status determination module determines whether a first ignition fuse is in a failure state. The open-loop fuel control module disables a first plurality of fuel injectors and actuates a second plurality of fuel injectors based on a first air/fuel (A/F) ratio when the first ignition fuse is in the failure state, wherein the first ignition fuse and the first plurality of fuel injectors correspond to a first cylinder bank, and wherein a second ignition fuse and the second plurality of fuel injectors correspond to a second cylinder bank.

    摘要: An engine control system includes a driver module and a diagnostics module. The driver module includes a high-side driver and a low-side driver, which selectively actuate a load. The driver module generates status signals based on detection of each of a plurality of failure modes of the high-side and low-side drivers. The diagnostics module increments a first error count for a first mode of the plurality of failure modes when the status signals indicate the driver module has detected the first mode. The diagnostics module increments a corresponding total count each time the driver module analyzes the first mode. The diagnostics module sets a fail state for a diagnostic trouble code (DTC) when the first error count for the first mode reaches a first predetermined threshold prior to the total count reaching a second predetermined threshold.

    摘要: An engine control system for a vehicle comprises a combustion control module and an engine startup module. The combustion control module selectively controls a spark timing and airflow into an engine based on a counter value. The engine startup module, when the counter value is one of greater than and less than a predetermined final value, controls an equivalence ratio (EQR) of an air/fuel mixture provided to the engine during an engine cranking period based on a fuel rail pressure and controls the EQR during an engine running period based on the fuel rail pressure and an engine runtime period. The counter value is set to the predetermined final value after the engine is started for a first time after the engine is assembled.
