Embodiment Construction

[0016] In order to facilitate the understanding of the technical solutions of the invention, the implementation of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Basic conditions: A voice-controlled microphone sensor or a headrest microphone sensor is installed near the front driver's seat in the car; the memory and processor of the on-board computer have data processing capabilities for noise signals, such as short-time Fourier transform, three-point One octave analysis, etc.; the resolution of the vehicle display screen can clearly display the noise spectrum color map; the vehicle has the function of the Internet of Vehicles.

[0018] 1) When the vehicle is normally powered on and started, the on-board trip computer terminal acquisition module collects the voltage signal of the in-vehicle voice microphone or headrest microphone sensor;

[0019] 2) Divide the collected voltage sign...

Abstract

The invention discloses an in-vehicle noise dynamic display and interaction method for enhancing user experience, and relates to the technical field of automobile detection, a vehicle-mounted trip computer terminal acquisition unit acquires a voltage signal and sensitivity of an in-vehicle voice microphone or a headrest microphone sensor; dividing the voltage signal by the sensitivity of the microphone to obtain time-varying data of the sound pressure in the vehicle; noise data changing along with time is converted into frequency domain data through short-time Fourier transform, an octave diagram changing along with frequency is calculated, and the frequency domain data and the octave diagram are displayed on a vehicle-mounted display screen in a time-frequency color diagram mode. The user experience can be enhanced, and dynamic acquisition, display and interaction of the noise in the automobile can be realized.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for dynamic collection, display and interaction of in-vehicle noise, which is used to enhance user experience and improve driving pleasure. Background technique [0002] With the continuous development of the automobile industry, people have higher and higher requirements for vehicle intelligence and driving comfort, and interior noise is an important indicator of comfort. During the operation of the car, noise will be generated, such as engine noise, transmission noise, wind noise, road noise, etc. If these noises can be dynamically displayed in real time and can interact with the user, it can enhance the user's perception of driving comfort. experience and enhance driving pleasure. [0003] Consumers and automakers are increasingly concerned about noise and vibration from vehicles. Vehicle intelligence focuses on the three major technologies of intelligent drivin...
