[0059] Exemplarily, the sensor array can collect sound data of 360-degree directions of the area where the vehicle is located, so as to avoid missing the voice instruction of the target object.

[0060] The voice data is subjected to voice filtering processing to remove noise data in the voice data, and valid data in the voice data can be obtained, wherein the valid data is data with valid information in the voice data.

[0061] Exemplarily, the low-frequency noise data and the high-frequency noise data in the voice data are removed through the band-pass filter, and the valid data in the voice data can be obtained.

[0065] In some embodiments, the embodiments of the present application provide a control method of a vehicle, and the method further comprises: In step S401, the voiceprint management module is controlled to collect voice data of a target object. In step S402, voiceprint features are extracted from the voice data to obtain voiceprint features in the voice data. In step S403, the voiceprint features are subjected to validity detection to obtain a confidence value of the voiceprint features. In step S404, in a case where the confidence value is greater than a confidence threshold, the voiceprint management module is controlled to store the voiceprint features to obtain second voiceprint information.

[0066] In this embodiment, the vehicle comprises a voiceprint management module, and the voiceprint management module is a management module for processing voice.

[0067] The voiceprint management module is controlled to collect voice data of a target object, wherein the voice data is voice data of the target object.

[0068] Voiceprint features are extracted from the voice data to obtain voiceprint features in the voice data, wherein the voiceprint features represent voiceprint features in the voice data.

[0080] In a case where the first voiceprint information is different from the second voiceprint information, it is determined that the identity permission is no permission.

[0081] In some embodiments, the embodiments of the present application provide a control method of a vehicle, which controls the opening and closing state of a vehicle door based on a voice instruction, comprising: Step S601, performing data format conversion on the voice instruction, so as to convert the voice instruction into a text instruction; Step S602, performing character recognition processing on the text instruction to obtain an instruction meaning; Step S603, based on the instruction meaning, control the opening and closing state of the vehicle door.

[0082] In this embodiment, the voice instruction is converted in data format to convert the voice instruction into a text instruction, wherein the text instruction is the text corresponding to the voice instruction.

[0083] For example, the vehicle can store a voice conversion model, which converts the voice instruction into text through the voice conversion model to obtain the text instruction corresponding to the voice instruction.

[0084] The text instruction is subjected to character recognition processing to obtain the instruction meaning, and based on the instruction meaning, the opening and closing state of the vehicle door is controlled, wherein the instruction meaning represents the specific meaning in the text instruction.

[0085] For example, the instruction meaning can be to open the vehicle door or close the vehicle door.

[0086] For example, the vehicle can store an instruction recognition model, which can obtain the instruction meaning by performing character recognition processing on the text instruction through the instruction recognition model.

[0088] In this embodiment, in the case that the instruction meaning is to open the vehicle door, the vehicle door is controlled to open, so that the vehicle door is in an open state.

[0089] In the case that the instruction meaning is to close the vehicle door, the vehicle door is controlled to close, so that the vehicle door is in a closed state.

[0090] For example, Figure 2 As shown, the vehicle can implement the following functions: Function 1, template voice instruction management.

[0091] The vehicle is in a specific mode, such as the vehicle is in P gear and the key is in the vehicle.

[0092] Similar to the car machine system or in the owner's mobile phone APP "vehicle settings-intelligent control" menu, there is a "tailgate voice management" sub-module, which contains three function buttons: "record open tailgate voice instruction", "record close tailgate voice instruction" and "delete stored voice instruction".

[0093] The voice command input process specifically includes: after clicking the corresponding button, the system prompts "Please say the command word (such as "Open the tailgate" or "Close the tailgate"), and the user needs to clearly say the command word within 3 seconds. The system automatically performs voiceprint feature extraction, environmental noise reduction processing and generates voice feature templates.

[0094] Upon successful completion, a message will appear saying "Command saved"; if unsuccessful, a message will appear saying "Please re-enter". A maximum of 5 commands can be saved for both opening and closing the tailgate, and each command has a preview playback function.

[0095] The command deletion mechanism includes: to enter the deletion mode for existing voice commands, press and hold the command entry for 2 seconds. Additionally, secondary confirmation is required (to prevent accidental operation).

[0096] After the command is entered, click "Confirm". The vehicle's ECU (Electronic Control Unit) will automatically transmit the voice command template to the gateway via the bus, and then to the tailgate voice control module of the area controller (which integrates the tailgate voice control module and the body control module) and save it.

[0097] The mobile app transmits the voice command template to the TBOX via the cloud service platform, then to the gateway via the bus, and finally to the tailgate voice control module of the area controller (which integrates the tailgate voice control module and the body control module) and saves it.

[0098] Function 2: Enter voice command receiving mode.

[0099] When the vehicle owner approaches the vehicle with a mobile phone or remote key configured with the digital key, the digital key module, which is always in polling mode, establishes a communication connection with the mobile phone / remote key at a pre-set distance. The key authentication process determines whether it is an authorized digital key / remote key. The digital key module then wakes up the area controller (integrating the tailgate voice control module and body control module), which in turn wakes up the power tailgate module. The area controller powers the voice sensors (shown as four examples in the diagram), waiting to receive voice commands and process tailgate actions.

[0100] Function 3: Acquisition of tailgate voice commands and tailgate control.

[0101] Multiple voice sensors ( Figure 2 The system consists of four voice sensors connected to the area controller, arranged in different positions at the rear of the vehicle to form a sensor array. In addition to being powered by the area controller, the voice sensors also have a signal transmission interface with it. The voice sensors integrate a signal filtering module to initially filter out noise signals.

[0102] The tail gate audio control module integrates the received voice signal to perform secondary filtering function. The received normal voice instruction is compared with the voice instruction template through software algorithm to determine whether it is the valid voice instruction of the vehicle owner. After the determination, the tail gate control command is sent to the body control module through the internal bus of the area controller, and then is transmitted to the electric tail gate module through the external bus. The electric tail gate module controls the strut motor to perform the opening or closing action of the tail gate through the hard-wire signal.

[0103] Function 4, sensor array locates the sound source.

[0104] The sensor array improves the clarity of the received voice signal and locates the sound source, for example, within 270° and 2m range at the back of the vehicle to be recognized as a valid voice instruction, preventing misoperation.

[0105] The sensor array sound source positioning, for example, uses a positioning method based on time delay difference estimation. First, the time difference of the sound source signal arriving at the voice sensor array is calculated, and then the sound source positioning model is established through the geometry of the voice sensor array and the position information is solved.
