Abstract

See full text

A system in a vehicle including at least one sound quality valve arranged in an exhaust system of the vehicle includes a sound quality valve control module that determines whether one or more criteria for opening the sound quality valve are met, selectively actuates the sound quality valve to an open position if the one or more criteria for opening the sound quality valve are met, and maintains the sound quality valve in a closed position if a required one of the one or more criteria for opening the sound quality valve is not met. A downshift detection module determines whether aggressive driving behavior is detected. If the aggressive driving behavior is detected, the sound quality valve control module actuates the sound quality valve to the open position regardless of whether the required one of the one or more criteria for opening the sound quality valve is met.
