Intelligent cockpit domain multi-tone-area Bluetooth audio playing method and device

Abstract

The invention discloses an intelligent cockpit domain multi-sound-area Bluetooth audio playing method and device, an intelligent cockpit is provided with a plurality of Bluetooth modules capable of wirelessly communicating with a Bluetooth earphone, the interior of the intelligent cockpit is divided into a plurality of sound areas, each sound area corresponds to an independent sound source transmission channel, and the sound source transmission channels are used for transmitting sound source data; the method comprises the following steps: identifying the identity of a calibrated Bluetooth headset, and performing wireless communication with the calibrated Bluetooth headset; the positioning information of the Bluetooth earphone is obtained through the Bluetooth module; calculating position information of the Bluetooth earphone according to the positioning information, and judging a sound area where the Bluetooth earphone is located; and matching and connecting the Bluetooth earphone with the sound source transmission channel of the sound area, and wirelessly transmitting the sound source data transmitted by the sound source transmission channel to the Bluetooth earphone, so that the Bluetooth earphone plays the sound source data of the sound area. According to the invention, the sound source data of the current sound area can be directly sent to the Bluetooth earphone of the current sound area, automatic adjustment is realized, and the security privacy is high.

Description

technical field [0001] The invention relates to a sound source playing in a smart cockpit, in particular to a method and device for playing Bluetooth audio in a smart cockpit with multiple sound zones. Background technique [0002] The traditional cockpit generally adopts a mechanical instrument panel and an embedded central control LCD screen, and each system is independent of each other, while the smart cockpit realizes the intelligent interaction between people, roads, vehicles, and clouds by carrying intelligent on-board equipment or services. Human-computer interaction (HMI) system constructed from the perspective of the scene. [0003] With the development of vehicle electronics in these years, especially the use of high-performance MCU in vehicle electronics. Vehicle electronic appliances mainly form a functional "domain" structure, and the smart cockpit is mainly composed of multiple domain controllers according to the corresponding structure. equipment. Compared ...

Problems solved by technology

However, this Bluetooth headset can only be connected to one smart terminal and the overall vehicle background server. When there are multiple occupants in the smart cockpit, it is impossible to provide corresponding audio source services for different occupants, and it is difficult to solve the problem of multi-audio source output in the smart cockpit.

[0005] Referring again to the Chinese patent CN201910108045.3, it discloses a sound partition control device in the smart cockpit, which realizes the directional transmission of sound through the strong directivity of the parametric speaker, so that the corresponding area in the smart cockpit can only receive the sound related to it. It is not only necessary to judge the head position of the occupant through special sound source detection, but also it is difficult to accurately send the sound to the head position when the head shakes and bows or does not make a sound, resulting in a poor experience

And it is still difficult to fully ensure the privacy and security among multiple occupants in the smart cockpit
