摘要： An automotive vehicle includes an internal combustion engine that generates exhaust gas and an exhaust system that expels the exhaust gas from the vehicle via at least one of a first exhaust conduit and a second exhaust conduit. A disturbance sensor is installed within a cabin of the vehicle, and is configured to detect a disturbance within the cabin and to output a disturbance signal indicative of the disturbance. An exhaust valve has a plurality of positions and adjusts an amount of the exhaust gas delivered to the first and second exhaust conduits. The automotive vehicle further includes an electronic hardware controller in signal communication with the at least one disturbance sensor and the exhaust valve. The controller adjusts the position of the exhaust valve based on the disturbance signal to reduce the disturbance within the cabin.

摘要： When the engine is off and not combusting fuel for one of an auto-stop portion of an auto-stop/start event and operation in a sail mode, a selection module sets at least one of: a selected torque based on a pseudo torque output of the engine; and a selected engine speed based on a pseudo engine speed determined for the one of the auto-stop portion of the auto-stop/start event and the operation in the sail mode. A sound control module, based on the at least one of the selected engine speed and the selected torque, sets at least one of: a frequency at which to output a predetermined engine sound; and a magnitude for outputting the predetermined engine sound at the frequency. An audio driver module applies power to at least one speaker of the vehicle to output the predetermined engine sound at the frequency and the magnitude.
