Abstract:
A throttle control system includes a target pressure module, a torque determination module, and a target opening module. The target pressure module determines an induction noise value based on an engine operating parameter and determines a target pressure downstream of a throttle valve of an engine based on a pressure at an inlet of the throttle valve and the induction noise value. The torque determination module determines a torque request for the engine based on the target pressure. The target opening module determines a target opening for the throttle valve based on the torque request and selectively adjusts opening of the throttle valve based on the target opening.
