摘要:
A system for a vehicle includes a desired mass air flowrate (MAF) module and a desired effective area module. The desired MAF module generates a desired MAF through a throttle valve of an engine based on an engine torque request. The desired effective area module generates a desired effective area of the throttle valve based on a throttle inlet air pressure (TIAP) and the desired MAF. A throttle actuator module adjusts opening of the throttle valve based on the desired effective area.
