Description

Technical Field

[0001] The present invention belongs to the field of vehicle data communication systems, and in particular, relates to a vehicle-mounted Bluetooth communication management method and system. Background Art

[0002] With the development of in-vehicle Bluetooth communication technology, users can answer calls without holding the phone while driving. In existing in-vehicle Bluetooth vehicles, users can talk to the Bluetooth-connected speakers at any location inside the vehicle, but Bluetooth cannot isolate the noise caused by non-callers, affecting the overall call effect.

[0003] In the Chinese authorized invention patent with patent number CN201910789389.5, a vehicle-mounted Bluetooth communication processing method, a vehicle-mounted audio management system and related equipment are disclosed. When receiving a phone call request sent by the vehicle-mounted Bluetooth module, the method broadcasts the phone call request to each sound zone in the car, collects audio data from each sound zone in the car, and detects the answering phone voice command from the collected audio data. When the answering phone voice command is collected from the first sound zone in the car, an answering phone response message is sent to the Bluetooth module. On the basis of the Bluetooth transmission of audio data between the Bluetooth module and the user's mobile phone, the audio data transmission between the Bluetooth module and the first sound zone is performed, so that the user in the first sound zone can answer the call and make a call. The above processing process enables the user in any sound zone of the car to answer the phone call connected to the vehicle-mounted Bluetooth module by voice, which reduces the pressure on the driver to answer the Bluetooth call, and at the same time facilitates the passengers in the car to make and receive calls.

[0004] The defect of the existing patent is that the above patent reduces the pressure on the driver to answer Bluetooth calls, and at the same time makes it convenient for passengers in the car to make and receive calls; but the car Bluetooth does not necessarily belong to the driver's personal communication phone. Sometimes the car Bluetooth is connected to the communication phone of the passengers in the car; the single noise reduction of other sound zones in the car cannot achieve the communication convenience of people in other sound zones using the car Bluetooth. Summary of the invention

[0005] In view of the problem that the existing in-vehicle Bluetooth communication system reduces the pressure on the driver to answer Bluetooth calls, but only reduces the noise in other sound zones in the car and cannot provide communication convenience for people in other sound zones using the in-vehicle Bluetooth, the present invention provides a method and system for in-vehicle Bluetooth communication management.

[0009] S2. When the vehicle-mounted Bluetooth system receives a phone call request, the vehicle-mounted Bluetooth system transmits the phone call request to the audio device in the vehicle audio zone where the Bluetooth mobile phone is connected to the vehicle, and simultaneously turns off or lowers the volume of the audio devices in other audio zones of the vehicle;

[0010] S3, judging whether the corresponding vehicle audio zone of the audio device feeds back a call connection instruction within the time preset by the vehicle Bluetooth system, if the call connection instruction is fed back, proceeding to step S4, if the call connection instruction is not fed back, proceeding to step S5;

[0011] S4, continuously receiving audio data transmitted by the audio equipment in the corresponding vehicle audio zone, feeding back the audio data to the mobile phone Bluetooth module, and playing the audio data sent by the mobile phone Bluetooth module to the corresponding vehicle audio zone;

[0012] S5. Restore the volume of all audio devices in the vehicle and relocate the vehicle sound zone where the Bluetooth mobile phone user is located.

[0013] Further, the method flow for determining whether the corresponding vehicle audio zone of the audio device feeds back a call connection instruction is as follows:

[0015] S302, the vehicle-mounted Bluetooth system converts the collected audio data into a recognizable character string;

[0016] S303, inputting the recognizable character string into the database of the vehicle-mounted Bluetooth system to search for identical or similar character strings; the searched recognizable character strings may include more than one, but as long as one character string is found to be identical or similar in the database, it can be determined that the feedback contains a call connection instruction.

[0017] S304: If the same or similar character string is found, it is determined that the feedback contains a call connection instruction;

[0018] S305: If no identical or similar character string is found, it is determined that there is no feedback of the call connection instruction.

[0019] Furthermore, the detailed steps of the car Bluetooth system to convert the collected audio data into a recognizable string are as follows:

[0020] S3021, reading the audio file as binary data;

[0021] S3022, encode the binary data into a Base64 string;

[0022] S3023. Save or output the encoded Base64 string. Base64 is a binary to text encoding method that can encode binary data into a string containing only ASCII basic characters.

[0023] Further, the detailed steps of step S5 are:

[0024] S501, adjusting the volume of all audio equipment in the vehicle to the same volume;

[0025] S502, the vehicle Bluetooth system resends a positioning request to the mobile phone Bluetooth module;

[0026] S503, the mobile phone user selects the vehicle audio zone where the Bluetooth mobile phone user is currently located according to the sent positioning request, and feeds back the selection result to the vehicle Bluetooth system;

[0027] S504: confirm the vehicle audio zone where the Bluetooth mobile phone user is located according to the selection result of the mobile phone user and the actual internal audio zone division of the vehicle.

[0028] Furthermore, the positioning request is to locate the virtual display interface of the vehicle sound zone, and according to the position of the virtual display interface selected by the user's mobile phone, it is confirmed to be the actual vehicle sound zone inside the vehicle where the mobile phone user is located.

[0031] The vehicle sound zone identification module is in communication connection with the Bluetooth communication connection module, and is used for when the mobile phone Bluetooth module establishes a communication connection with the vehicle Bluetooth system, the vehicle Bluetooth system sends a positioning request to the mobile phone Bluetooth module, and the mobile phone user selects the vehicle sound zone where the Bluetooth mobile phone user is currently located according to the sent positioning request, and feeds back the selection result to the vehicle Bluetooth system, and confirms the vehicle sound zone where the Bluetooth mobile phone user is located according to the selection result of the mobile phone user and the actual vehicle internal sound zone division;

[0032] A call-connection command collection and judgment module is used to judge whether the corresponding vehicle audio zone of the audio device feedbacks the call-connection command;

[0033] The module for re-locating the vehicle audio zone where the user is located is connected to the module for collecting and judging the call connection command, and is used to relocate the vehicle audio zone where the Bluetooth mobile phone user is located for the corresponding vehicle audio zone that has not fed back the call connection command;

[0034] Bluetooth audio device configuration module, used to configure the communication method between the vehicle Bluetooth system and the audio device, and to authorize the adjustment of the volume and control switch of the entire vehicle audio device;

[0035] The audio data matching module is in communication connection with the call connection instruction collection and judgment module, and is used to search the database of the vehicle-mounted Bluetooth system for the same or similar character strings for the audio data collected by the call connection instruction collection and judgment module.
