摘要： A system for a parallel intake engine includes first, second, third, and fourth modules. The first module estimates a total mass air flow (MAF) into the engine based on a cross-sectional area of a throttle and a pressure ratio across the throttle. The second module estimates first and second MAFs through first and second induction paths, respectively, based on the estimated total MAF and a factor. The third module calculates first and second differences between the estimated first and second MAFs and first and second MAFs measured by first and second MAF sensors, respectively. The fourth module detects failures of the first and second MAF sensors based on the first and second differences and first and second thresholds, respectively.

摘要： An air-per-cylinder (APC) security system for a vehicle comprises an APC determination module, an APC threshold determination module, and an APC diagnostic module. The APC determination module determines first and second APC values for first and second cylinders of an engine, respectively, based on mass airflow (MAF) into the engine.

摘要： A system for a vehicle includes a humidity determination module, a specific humidity module, and a parameter control module. The humidity determination module determines a first specific humidity of air based on a relative humidity of the air measured by a humidity sensor in an intake system of the vehicle. The specific humidity module sets a second specific humidity of the air equal to one of the first specific humidity and a predetermined specific humidity of the air in response to a comparison of a mass air flowrate (MAF) into an engine and a predetermined flowrate. The parameter control module controls at least one operating parameter of an engine based on the second specific humidity.

摘要： An engine control system comprises a signal deviation module, a variation determination module, and a sensor diagnostic module. The signal deviation module receives a signal from a sensor monitoring an operating condition of an engine and determines a plurality of signal deviations. Each of the plurality of signal deviations is based on a magnitude of a difference between the signal at a first time and the signal at a second time. The second time is different than the first time. The variation determination module generates a variation value based on the plurality of signal deviations during a period. The sensor diagnostic module determines a state of the sensor based on the variation value.
