摘要： A method of monitoring air flow restriction in an air intake of an internal combustion engine includes monitoring a plurality of manifold absolute pressure (MAP) samples and determining respective MAP thresholds corresponding to each of the MAP samples. Each of the MAP samples is compared to its respective MAP threshold. A percentage of failed MAP samples is determined based on the comparing and an over-restricted air intake condition is selectively indicated based on the percentage of failed MAP samples.

摘要： A method of monitoring air flow restriction in an air intake of an internal combustion engine includes recording a predetermined number of pre-throttle pressure samples, recording a predetermined number of mass air flow samples, which respectively correspond to the pre-throttle pressure samples and determining a slope based on the pre-throttle pressure samples and the mass air flow samples. Whether an air filter is inducing an air flow over restriction is determined based on the slope.

摘要： An engine control system for regulating operation of an engine having a throttle includes a first module that determines an intermediate parameter based on engine operating parameters and a second module that determines a pressure upstream of the throttle based on the intermediate parameter. A third module regulates operation of the engine based on the pressure. The engine operation is regulated based on a pre-determined relationship between a throttle position and an effective throttle area.

摘要： A vehicle simulation system includes a first simulation model that when executed simulates a software ring along with other software of a vehicle module. The vehicle simulation system further includes a second simulation model of the software ring. A bypass switch that has a first state and a second state. A bypass switching module switches the bypass switch between the first simulation model and the second simulation model based on a bypass signal and a ring enabling signal. A simulation control module executes code of a vehicle simulation model including software in-the-loop (SIL) testing of a selected one of the first simulation model and the second simulation model based on state of the bypass switch.
