Embodiment 1
[0056] Such as figure 1 As shown, this embodiment provides a call noise reduction method, including:
[0057] Step 1, when detecting the Bluetooth hands-free call is turned on, the driving position window, the widewalk window state is detected.
[0058] Step 2, when the driver's seat window is detected, the width booth window is in an open state, obtains the external environmental noise and wind noise information outside the vehicle.
[0059] Wind noise is generated when the airflow flows from the microphone port or the flow of the microphone, and the wind noise information outside the vehicle is acquired by the wind-to-noise microphone.
[0060] The external environmental noise is noise other than wind noise.
[0061] When a microphone is installed, the air noise and the external environmental noise can be identified based on the characteristics of wind noise, external noise, based on the speech recognitionalgorithm.
[0062] When two microphones are installed, one microphone ac...
Embodiment 2
[0095] Such as figure 2 As shown, this embodiment provides a call noise reduction device, including:
[0096] The call monitoring module, the window position acquisition module, the noise acquisition module, the first execution module, the first execution module, the first execution module, the first execution module, the first execution module, and the first execution module, the first execution module, and the first execution module;
[0097] The call monitoring module is configured to detect the call status of the Bluetooth phone;
[0098] The window position acquisition module is used to obtain a driving bit window, a wound pick-up window state;
[0099] The noise acquisition module is used to obtain external environmental noise and wind noise;
[0100] The first execution module is configured to control the lifting of the driver's window;
[0101] The second execution module is configured to control the lifting of the width driving position window;
[0102] The prompt module ...

Abstract
The invention provides a noise reduction method and device for a call. The method comprises the steps of detecting states of a vehicle window of a driver seat and a vehicle window of a co-driver seat when a Bluetooth hands-free call is detected to be connected; when it is detected that the vehicle window of the driver seat and the vehicle window of the co-driver seat are in an opened state, obtaining information of external environment noise and wind noise outside a vehicle; and according to the external environment noise and the wind noise, controlling lifting of at least one vehicle window of the driver seat and the co-driver seat. According to the method and device, when encountering noisy environmental noise in the call process, the vehicle window can be automatically controlled to ascend and descend under the condition that the vehicle window is not completely closed, the call quality is kept, and the driving experience is improved.
Description
Technical field [0001] The present invention relates to the field of assist driving technology, and more particularly to a call noise reduction method and apparatus. Background technique [0002] At present, the car information entertainment system has become more popular in the automotive, enriched the journey of the company, in which Bluetooth hands-free function (HFP) enables the driver to complete the other party through the in-vehicle info entertainment system and car speaker. . [0003] However, the driver passed HFP during the window driving process, because the car inside and outside the environment is too large, can't understand the words of the other party, causing the call quality to decline, the driver must have more energy on the call, easy to make traffic accident. [0004] Therefore, the prior art needs further improvement. Inventive content [0005] The present invention provides a call noise reduction method and apparatus aimed at solving the deficiencies in the...
