Problems solved by technology

While such suppression systems may provide a relatively quiet and comfortable environment within the vehicle, such an environment may not be desirable under certain circumstances
For example, when driving conditions are difficult, sound suppression systems can impede a driver's ability to drive safely by masking road noise that would otherwise provide the driver with greater alertness

Embodiment Construction

[0017] Certain terms are used throughout the following description and claims to refer to particular system components and configurations. As will be appreciated by those skilled in the art, companies may refer to components by different names. This document does not intend to distinguish between components that differ in name but not function. In the following discussion and in the claims, the terms "comprises" and "comprises" are used in an open form, and should therefore be construed to mean "including, but not limited to...". The terms "coupled", "coupled" or "couplable" are intended to mean an indirect or direct electrical or wireless connection. Thus, if a first device couples to a second device, that connection may be through a direct electrical, optical, wireless connection, etc., or through an indirect electrical, optical, wireless connection by means of other devices and connections and many more.

[0018] One or more embodiments of the invention are described bel...

Abstract

An apparatus for controlling sound within a vehicle includes an acoustical damping device operable to determine a measured sound. The acoustical damping device is operable to output a noise canceling signal to a vehicle audio system to dampen the measured sound. A sound controller is operably coupled to the acoustical damping device and is configured to automatically receive an environment signal from an environment sensor. The sound controller is configured to determine an operating mode of the vehicle based on the environment signal. The operating mode is selectable from an operating mode list that includes a stress operating mode and a calm operating mode. The sound controller is configured to cause alteration of the noise canceling signal and reduction in damping in the stress operating mode with respect to the calm operating mode.

Description

technical field [0001] The present invention generally relates to systems for active control of sound in motor vehicles. Background technique [0002] Occupants of a motor vehicle typically hear many sounds, including those originating outside the vehicle (such as nearby airplanes, cars, and trains), as well as sounds produced by the vehicle (including road noise, sounds emitted by the vehicle's powertrain, and other vehicle part sound). Some vehicles include sound suppression systems designed to alter the effect of the overall sound environment in the vehicle, typically by suppressing some of the various sounds heard by the driver and / or passengers. [0003] In some vehicles, the suppression system provides a noise canceling signal to reduce the noise heard in the vehicle. These systems can be preset by the manufacturer or supplier to accomplish a desired amount of sound suppression within the vehicle. While such suppression systems may provide a relatively quiet and com...
