Embodiment Construction

[0013] The following detailed description is merely exemplary in nature and is not intended to limit the disclosure, its application, or uses. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description. For example, the audio sensor and playback device of the present invention has particular application for use in vehicles. However, as will be understood by those skilled in the art, the sensor and playback device of the present invention may have other applications in systems other than vehicles.

[0014] Modern vehicles sometimes include various active safety and control systems, such as collision avoidance systems, adaptive cruise control systems, lane keeping systems, lane centering systems, noise and vibration suppression systems, etc., where vehicle technology is moving towards semi-autonomous driving and fully autonomous driving vehicle development. For example, noise and vibration suppressio...

Abstract

The present application generally relates noise and vibration mitigation in a vehicle. More specifically, the application teaches a system and method for applying a noise and vibration constraint to avehicle subsystem, measuring a sound level within the vehicle cabin, determining the sound level exceeds a threshold level making the noise constraint redundant and removing the noise constraint in response to the sound level exceeding the threshold level.

Description

technical field [0001] The subject matter of the present disclosure relates generally to noise and vibration control systems for automobiles, and more particularly to the use of vehicle interior audio sensors and other vehicle sensors to actively assess masking noise relative to thresholds and eliminate noise and vibration restrictions, thereby improving vehicle efficiency. Background technique [0002] Vehicle subsystems often include noise and vibration limitation systems to reduce passenger compartment noise and improve occupant comfort. For example, the rear differential control module may have noise and vibration limits that lock the clutch to avoid gear rattle or limit torque to avoid hypoid gear noise. These limitations affect the vehicle's efficiency and all-wheel-drive performance in order to achieve acceptable noise and vibration levels. However, sometimes these noise and vibration limits apply where the application is not required. These situations could include...
