Abstract
Vehicle sound attenuation systems and methods are provided herein. An example method includes determining a triggering event for a vehicle using an advanced driver assisted technology system, and controlling a sound enhancing system of the vehicle in response to the triggering event. Controlling the sound enhancing system may include attenuating engine or exhaust sound produced by the sound enhancing system of the vehicle.
Claims20
A method, comprising:
- determining a triggering event for a vehicle using an advanced driver assistance technology system;
- controlling a sound enhancing system of the vehicle in response to the determination of the triggering event, wherein controlling the sound enhancing system includes attenuating engine or exhaust sound produced by the sound enhancing system of the vehicle, and wherein the controlling of the sound enhancing system is at least partially based on at least one of a drive mode, a convertible state, an engine order, an engine RPM, a pedal position, and an engine torque;
- and
- wherein attenuating engine or exhaust sound includes controlling an exhaust tuning valve system of the sound enhancing system by at least partially opening or closing an adjustable position valve of the exhaust tuning valve system, wherein at least partially opening or closing the adjustable position valve is at least partially based on at least one of an exhaust mode, a gear selection, the engine RPM, and the pedal position.
1 more element
A system, comprising:
- a sound enhancing system of a vehicle, wherein the sound enhancing system comprises an exhaust tuning valve system;
- and
- a controller comprising a processor and a memory, the processor executing instructions stored in the memory to:
- determine a triggering event for a vehicle, the triggering event being indicative of a dangerous driving condition for the vehicle;
- and
- control the sound enhancing system of the vehicle in response to the determination of the triggering event, wherein control of the sound enhancing system includes attenuation of engine or exhaust sound produced by the sound enhancing system of the vehicle, and wherein the controlling of the sound enhancing system is at least partially based on at least one of a drive mode, a convertible state, an engine order, an engine RPM, a pedal position, and an engine torque;
- and
- wherein attenuating engine or exhaust sound includes controlling the exhaust tuning valve system by at least partially closing an adjustable tuning valve of the exhaust tuning valve system, wherein at least partially closing the adjustable position valve is at least partially based on at least one of an exhaust mode, a gear selection, the engine RPM, and the pedal position.

A vehicle, comprising:
- a processor and a memory, the processor executing instructions stored in the memory to:
- determine a triggering event using an advanced driver assistance technology system;
- and
- control a sound enhancing system of the vehicle in response to the determination of the triggering event, wherein the sound enhancing system comprises an exhaust tuning valve system having an adjustable position valve, and wherein the controlling of the sound enhancing system is at least partially based on at least one of a drive mode, a convertible state, an engine order, an engine RPM, a pedal position, and an engine torque;
- and
- wherein controlling the sound enhancing system includes attenuating engine or exhaust sound produced by the sound enhancing system of the vehicle, wherein attenuating engine or exhaust sound includes at least partially closing the valve, wherein at least partially closing the adjustable position valve is at least partially based on at least one of an exhaust mode, a gear selection, the engine RPM, and the pedal position.
