[0048] Figure 1 A vehicle recording method provided by an exemplary embodiment of the present application is applied to a vehicle intelligent communication terminal T-BOX, and the recording method includes:

[0049] S11. Determine a vehicle audio signal through a voice module of the vehicle.

[0050] The voice module may be a voice call unit, a vehicle microphone or a driving recorder of the vehicle, and the vehicle microphone may be arranged on the driving recorder. When the voice module is a voice call unit, the voice call unit is used for the driver and passengers to make phone calls in the vehicle; when the voice module is a vehicle microphone or a driving recorder, the vehicle microphone or the driving recorder is used to capture the voice of the driver and passengers and record the audio signal during the driving or parking of the vehicle.

[0051] The vehicle audio signal is an audio signal within a preset range of the vehicle. The audio signal within the preset range of the vehicle can be an audio signal inside the vehicle or an audio signal within a preset range outside the vehicle. The preset range is set according to actual conditions, for example, 5 meters.

[0052] The vehicle audio signal may be a sound wave or a digital signal converted from a sound wave. Different types of vehicle audio signals may be determined according to different units in the voice module. The following further describes different types of vehicle audio signals determined by different units of the voice module.

[0053] In one embodiment, determining a vehicle audio signal through a voice module of the vehicle includes:

[0054] When the voice module is a voice call unit, the voice call audio signal of the voice call unit is recorded as a vehicle audio signal;

[0055] When the voice module is a vehicle-mounted microphone, the microphone audio signal recorded by the vehicle-mounted microphone is the vehicle audio signal.

[0056] T-BOX is equipped with an audio module, which can be used to record, receive and store audio signals. The vehicle's intelligent communication terminal T-BOX (Telematics Box) and the vehicle's voice module are connected via a CAN line (Controller Area Network). The audio module of T-BOX can determine the vehicle's audio signal through the vehicle's voice module.

[0057] When the voice module is a voice call unit, the voice call unit can be a vehicle-mounted call device, and the driver and passengers can make vehicle-mounted telephone calls through the vehicle-mounted call device. The voice call unit can be, for example, a vehicle-mounted Bluetooth phone, a vehicle-mounted phone, a vehicle-mounted call system, a vehicle-mounted communication system, etc.

[0058] When the driver and passengers make a phone call through the voice call unit, the audio module of T-BOX can record the voice call audio signal of the voice call unit as the vehicle audio signal, which includes the call audio signal of the user in the car and the call audio signal of the other end. At this time, the type of vehicle audio signal is sound wave. T-BOX captures the sound wave in the voice call unit, and records the voice call audio signal as the vehicle audio signal by collecting the sound waves during the call.

[0059] By connecting the vehicle's T-BOX and voice module, the T-BOX is used to record the voice call audio signal in the voice module to meet the user's needs for vehicle call recording.

[0060] When the voice module is a vehicle microphone or a driving recorder, the vehicle microphone or driving recorder is used to record the audio signal during the driving process or when the vehicle is parked. The microphone audio signal recorded by the vehicle microphone is received by T-BOX as a vehicle audio signal, and the microphone audio signal includes the audio signal inside the vehicle and the audio signal within a preset range outside the vehicle. At this time, the type of the vehicle audio signal is a digital signal. T-BOX receives the digital signal transmitted by the vehicle microphone or driving recorder to obtain the vehicle audio signal recorded by the vehicle microphone or driving recorder through the digital signal.

[0061] The audio channel of the dashcam depends on the audio collection function of the dashcam, which can only collect local sound. For example, when there is an incoming call, the sound on the other end of the microphone cannot be collected, so the complete call recording cannot be achieved. By using T-BOX to determine the vehicle audio signal, it can collect and record the sound on the other end of the microphone by connecting to the vehicle's voice module to achieve complete call recording, meeting the user's demand for vehicle call recording, and the cost of adding a recording function under the audio module of T-BOX is low, which can reduce the cost of hardware purchase, maintenance and upgrade.

[0062] In one embodiment, determining a vehicle audio signal through a voice module of the vehicle includes:

[0063] In response to receiving a call instruction from the voice call unit, a voice call audio signal of the voice call unit is recorded as a vehicle audio signal.

[0064] When the voice call unit is about to make a call, for example, when answering a call through a button on the vehicle display, the voice call unit sends a call instruction to the T-BOX, and the MCU (Microcontroller Unit) in the T-BOX controls the audio module to start recording, and the voice call audio signal of the voice call unit is recorded as the vehicle audio signal. When the voice call unit is making a call, recording is turned on to reduce unnecessary data storage, such as reducing the storage memory of the T-BOX occupied by non-voice call audio signals to store more voice call audio signals.

[0065] In one embodiment, determining a vehicle audio signal through a voice module of the vehicle includes:

[0066] According to the command sent by the in-vehicle infotainment system IVI, determine the preset strategy corresponding to the command;

[0067] Execute the preset strategy to obtain the vehicle audio signal.

[0068] The in-vehicle infotainment system IVI (In-Vehicle Infotainment) is equipped with a UI (User Interface) interface for human-computer interaction between the driver and the vehicle. The driver and the passenger click on different operations on the UI interface, and the IVI sends different instructions to the T-BOX. In response to the different instructions sent by the IVI, the T-BOX determines and executes the preset measures corresponding to the instructions, such as switching the recorded voice call audio signal to the received microphone audio signal to obtain the vehicle audio signal.

[0069] In one embodiment, according to the instruction sent by the in-vehicle infotainment system IVI, determining a preset strategy corresponding to the instruction includes:

[0070] In response to receiving a first power-off instruction sent by the IVI, determining that a preset strategy corresponding to the first power-off instruction is a first strategy.

[0071] The first strategy includes: turning on a backup power supply; determining a vehicle audio signal through power provided by the backup power supply; and a first power-off instruction indicating that power to the IVI is lost.

[0072] When the dash cam is recording, it is integrated into the vehicle computer. The power supply of the dash cam depends on the power supply of the vehicle. When the vehicle loses power in an emergency, the dash cam cannot record. The T-BOX is equipped with a backup power supply. When the IVI sends the first power-off command, it indicates that the power of the IVI is lost. At this time, there may be an emergency, such as the loss of the power of the vehicle during a collision, and the vehicle is in a power-off state. The power supply of the IVI is provided by the power supply of the vehicle, and the T-BOX is provided with a separate backup power supply in addition to the power supply provided by the vehicle power supply. Under normal circumstances, both the IVI and the T-BOX are powered by the power supply of the vehicle. The IVI can detect whether the power of the vehicle is lost. When the IVI sends the first power-off command, it indicates that the power of the vehicle is lost. At this time, the T-BOX can enable the backup power supply and continue to determine the vehicle audio signal within the first time period. The first time period is set according to the actual situation, for example, 10 minutes, or 15 minutes. Since T-BOX is equipped with a backup power supply, even if the power is cut off in an emergency, the backup power supply can support the vehicle to record the last few minutes of vehicle audio signals to restore the final situation in the car to the greatest extent.

[0073] In one embodiment, according to the instruction sent by the in-vehicle infotainment system IVI, determining a preset strategy corresponding to the instruction includes:

[0074] In response to receiving a second power-off instruction sent by the IVI, determining that the preset strategy corresponding to the second power-off instruction is the second strategy.

[0075] The second strategy includes: turning on the backup power supply; determining the vehicle audio signal at a preset interval through the power provided by the backup power supply; and a second power-off instruction indicating that the power of the IVI is lost.

[0076] T-BOX is equipped with a backup power supply. When IVI sends the second power-off command, it indicates that the power of IVI is lost. At this time, an emergency may occur, such as the vehicle is in a power-off state during a collision. The power supply of IVI is provided by the power supply of the whole vehicle, and T-BOX is provided with a separate backup power supply in addition to the power supply of the whole vehicle. Under normal circumstances, both IVI and T-BOX are powered by the power supply of the whole vehicle. IVI can detect whether the power supply of the whole vehicle is lost. When IVI sends the second power-off command, it indicates that the power supply of the whole vehicle is lost. At this time, T-BOX can enable the backup power supply, interval the preset time, and determine the vehicle audio signal within the second time length. The second time length and the preset time length are set according to the actual situation. For example, the preset time is 3 minutes and the second time length is 2 minutes. At this time, every 3 minutes interval, the vehicle audio signal within 2 minutes is determined. Since T-BOX is equipped with a backup power supply, even if the power supply is cut off in an emergency, the backup power supply can supply power, and the vehicle audio signal is determined at intervals of preset time, which can extend the battery life of the backup battery to restore the last situation in the car to the greatest extent.

[0077] In one embodiment, according to the instruction sent by the in-vehicle infotainment system IVI, determining a preset strategy corresponding to the instruction includes:

[0078] In response to receiving the switching instruction sent by the IVI, it is determined that the preset strategy corresponding to the switching instruction is the third strategy.

[0079] Among them, the third strategy includes: ending the determination of the vehicle audio signal.

[0080] The vehicle includes two recording modes, one for T-BOX recording and the other for driving recorder recording. When the IVI sends a switching command, it instructs the driver to select the switch recording mode in the UI interface. At this time, the recording is switched to the driving recorder, and T-BOX can end the determination of the vehicle audio signal. When the driver chooses to switch the recording mode again, the recording is switched from the driving recorder to the T-BOX recording. Providing the recording mode of the driving recorder as an alternative, when a problem occurs in one recording mode, switching to another recording mode can increase the fault tolerance of the vehicle recording and ensure the integrity of the vehicle audio signal determination.

[0081] S12: Perform format conversion on the vehicle audio signal to obtain a vehicle audio file.

[0082] The vehicle audio signal carries vehicle audio information, which refers to information transmitted through sound, usually transmitted in the form of sound waves in a medium such as air, and / or in the form of electric current in a medium such as a signal line. For example, the vehicle audio information can be any form of sound recording such as music, calls, conversations, broadcasts, etc. in the vehicle. Format conversion of the vehicle audio signal can be performed to extract and encapsulate the vehicle audio information carried in the vehicle audio signal to obtain a vehicle audio file containing the vehicle audio information.

[0083] When the voice module is a voice call unit, the audio module of T-BOX can record the voice call audio signal of the voice call unit as a vehicle audio signal. T-BOX captures the sound waves in the voice call unit, and records the voice call audio signal as a vehicle audio signal by collecting the sound waves during the call. At this time, the type of the vehicle audio signal is a sound wave. After T-BOX records the vehicle audio signal, it converts the sound wave of the vehicle audio signal into a digital signal, encodes and encapsulates the digital signal to obtain a vehicle audio file that conforms to the storage format of T-BOX, such as MP3 format, WAV format, FLAC format, etc.

[0084] When the voice module is a vehicle microphone or a driving recorder, the vehicle microphone or driving recorder is used to record the audio signal during the driving process or when the vehicle is parked. T-BOX receives the digital signal transmitted by the vehicle microphone or driving recorder to obtain the vehicle audio signal recorded by the vehicle microphone or driving recorder through the digital signal. At this time, the type of the vehicle audio signal is a digital signal. After receiving the digital signal transmitted by the vehicle microphone or driving recorder, T-BOX encodes and encapsulates the digital signal to obtain a vehicle audio file that conforms to the T-BOX storage format, such as MP3 format, WAV format, FLAC format, etc.

[0085] S13: storing the vehicle audio file.

[0086] In one embodiment, storing the vehicle audio file includes: storing the vehicle audio file in a preset storage area in the T-BOX.

[0087] After obtaining the vehicle audio file that conforms to the T-BOX storage format, the vehicle audio file is stored in the preset storage area in the T-BOX, which can realize near-end recording and store it locally. The audio acquisition and video acquisition of the driving recorder are integrated together. When the video is acquired, the corresponding audio signal is obtained. The video acquisition and audio acquisition affect each other. For example, when the video cannot be acquired, the corresponding audio cannot be acquired. In addition, the video file and audio file of the driving recorder are stored at the same time. The files are large and occupy more storage space. Compared with the above defects of the driving recorder, using T-BOX to record and store vehicle audio files, the vehicle audio file can be obtained without acquiring video. The stored vehicle audio file is smaller, and more vehicle audio signals can be recorded and stored. In addition, the recording of vehicle audio signals by T-BOX is not affected by the camera, which reduces the problems caused by the recording of audio signals when there are defects in video acquisition.

[0088] Alternatively, in one embodiment, the vehicle audio files may also be stored in a cloud server to implement storage of the vehicle audio files.

[0089] T-BOX is equipped with a NAD (Network Access Device) communication module. After obtaining the vehicle audio file that conforms to the T-BOX storage format, the NAD communication module uploads the vehicle audio file to the cloud server, which can realize remote recording, such as transmitting to a remote server or cloud storage through the NAD communication module. The vehicle audio file stored in T-BOX is small, so there are fewer processes to upload to the cloud server and the transmission speed is faster. The cloud server can provide automatic backup function to reduce the risk of data loss, and users can access the vehicle audio files in the cloud server from a place with a network connection, improving the user experience. Compared with the traditional storage in the preset storage area in T-BOX, storage in the cloud server can reduce the cost of hardware purchase, maintenance and upgrade.

[0090] Combine the following Figure 2-Figure 4 , further explanation of the vehicle recording method:

[0091] like Figure 2As shown, when the driver or passenger chooses to turn on the audio signal determination function in the UI interface of IVI, IVI transmits a first start signal to T-BOX through the CAN line, instructing T-BOX to turn on the audio signal determination function, and the MCU in T-BOX responds to the first start signal, turns on the audio signal determination function in the audio module, and records the voice call audio signal of the voice call unit as a vehicle audio signal or receives the microphone audio signal recorded by the vehicle microphone as a vehicle audio signal. Send the command AT+CREC=1, then determine to store the vehicle audio file locally in T-BOX, name the vehicle audio file: address: / file name.format, and store the vehicle audio signal in the preset storage area in T-BOX after determining it. When the determination of the vehicle audio signal is finished, send the command AT+CREC=0. When the vehicle audio signal needs to be stored in the cloud server, the vehicle audio signal is uploaded to the cloud server. When the MCU sends an AT (Attention command) instruction, such as a second start signal, to the LTE (Long Term Evolution) unit in the NAD communication module, AT+CREC=2, it is determined that the vehicle audio file is stored in the cloud server, and the vehicle audio file is named: address: / file name.format. At this time, the LTE unit responds to the second start signal to upload the vehicle audio signal to the cloud server.

[0092] like Figure 3 As shown, when the driver or passenger chooses to switch the recording mode in the UI interface of IVI, IVI transmits the first shutdown signal to T-BOX through the CAN line, instructing T-BOX to turn off the audio signal determination function. The MCU in T-BOX responds to the first shutdown signal and turns off the audio signal determination function in the audio module. At this time, it switches to the driving recorder for recording. T-BOX can end the determination of the vehicle audio signal and sends the command AT+CREC=1, then it is determined that the vehicle audio file is stored in the T-BOX local, and the vehicle audio file is named: address: / file name. format. After the vehicle audio signal is determined, it is stored in the preset storage area in T-BOX. When it is necessary to store the vehicle audio signal in the cloud server, the vehicle audio signal is uploaded to the cloud server. When the MCU sends an AT command such as the second shutdown signal to the LTE unit in the NAD communication module, it sends the command AT+CREC=2, then it is determined that the vehicle audio file is stored in the cloud server, and the vehicle audio file is named: address: / file name. format. At this time, the LTE unit responds to the second shutdown signal to upload the vehicle audio signal to the cloud server.

[0093] like Figure 4As shown, when the IVI is powered off, the IVI transmits the first power-off instruction to the T-BOX through the CAN line, indicating that the power of the IVI is lost. At this time, an emergency may occur, such as the vehicle is in a power-off state during a collision. The MCU in the T-BOX responds to the first power-off instruction, enables the backup power supply, and continuously determines the vehicle audio signal within a first time period, for example, determines that the vehicle audio signal is continuously determined within 5 minutes. Then send a third shutdown signal to the MCU, the MCU responds to the third shutdown signal, turns off the backup power supply, and stores the vehicle audio signal in a preset storage area in the T-BOX. When the vehicle audio signal needs to be stored in the cloud server, the vehicle audio signal is uploaded to the cloud server, and the MCU sends an AT instruction such as a fourth shutdown signal to the LTE unit in the NAD communication module, and the LTE unit responds to the fourth shutdown signal to upload the vehicle audio signal to the cloud server. When the IVI is powered off, the IVI transmits the second power-off instruction to the T-BOX through the CAN line, indicating that the power of the IVI is lost. At this time, an emergency may occur, such as the vehicle is in a power-off state during a collision. The MCU in the T-BOX responds to the second power-off instruction, enables the backup power supply, and determines the vehicle audio signal within the second time period at a preset interval, for example, every 3 minutes, determines the vehicle audio signal within 2 minutes. Then, the fifth shutdown signal is sent to the MCU. The MCU responds to the fifth shutdown signal, shuts down the backup power supply, and stores the vehicle audio signal in a preset storage area in the T-BOX. When the vehicle audio signal needs to be stored in the cloud server, the vehicle audio signal is uploaded to the cloud server. The MCU sends an AT command such as the fifth shutdown signal to the LTE unit in the NAD communication module. The LTE unit responds to the fifth shutdown signal to upload the vehicle audio signal to the cloud server.

[0094] It should be understood that although Figure 1-4 The various steps in the flowchart of FIG. XY are displayed in sequence according to the indication of the arrows, but these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in FIG. XY may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps.
