Method and device for automatic regulation of navigator voice broadcasting volume

Abstract

The invention provides a method and a device for automatic regulation of navigator voice broadcasting volume. The technical scheme of the invention is that: an ambient noise detecting device is controlled by an ambient noise detecting control module to detect external ambient noise volume so as to obtain an ambient noise decibel value; the obtained ambient noise decibel value is converted into a corresponding volume order N by a processing module; the volume order N is compared with a default volume order Ndefault of the voice broadcasting system of the navigator; if the volume order N is higher than the default volume order Ndefault, the volume of the voice broadcasting system is regulated to be a volume order equal to or higher than the volume order N; if not, the volume of the voice broadcasting system is maintained to be the default volume order Ndefault. Through the combination of the intelligent voice broadcasting system, the navigator of the invention has improved driving safety and comfort.

Description

【Technical field】 [0001] The invention relates to the field of navigation, in particular to a method and a device for automatically adjusting the voice broadcast volume of a navigator. 【Background technique】 [0002] Car navigators have become more and more integrated into people's lives, providing great convenience for people who are new to driving or unfamiliar with road conditions. Manufacturers of navigation products have sprung up, and navigation products are becoming more and more abundant. There are more and more choices for users, but there are common defects in many existing navigation products, that is, drivers often need to operate the navigator during driving, especially to adjust the volume. To clearly hear the navigation broadcast voice, the driver needs to lean forward to operate the volume adjustment device of the navigator, which will inevitably have a certain impact on driving and even unpredictable traffic accidents, which will bring huge economic losses t...
