Unlocking method and system

[0027] Example one:

[0028] figure 1 It is a schematic flowchart of the unlocking method provided in the first embodiment of the present invention. In order to clearly describe the unlocking method provided in the first embodiment of the present invention, please refer to figure 1.

[0029] The unlocking method provided in the first embodiment of the present invention, applied to a vehicle, includes the following steps:

[0030] S101: When the vehicle sensor detects the user's sensing information, it generates and sends wake-up information to the control module.

[0031] In one embodiment, the vehicle-mounted sensor may be provided at the door of the vehicle so as to detect the user's intention to unlock, and the vehicle-mounted sensor may be an infrared sensor, an image sensor, a human body sensor, etc., capable of detecting the proximity of a human body. The user-sensed information is information that the on-board sensor triggers a corresponding operation. The user-sensed information in the present invention is generally understood as the user (person) approaching the vehicle. In one embodiment, the vehicle-mounted sensor is an infrared sensor, which can recognize the temperature of an object close to the door, and because a person is a thermostatic animal with a fixed body temperature, through the setting of the infrared sensor, the object close to the door can be accurately identified Whether it is a person, so as to realize that only when a person approaches the door, the on-board sensor will generate and send a wake-up message to the control module.

[0032] In one embodiment, before step S101, that is, before the vehicle-mounted sensor detects user sensing information, the method further includes the step: the control module sends a voiceprint (sound information) setting command to the audio device, so that the audio device turns on the recording function and receives the user Sound to generate the first sound information, so that the first sound information is set as the preset sound information. Therefore, when the user initially uses the vehicle with this unlocking method, he can personalize the preset voice information to identify a specific user (the owner), and the user needs to change the preset voice information during the subsequent use of the vehicle. For voice information, this step can also be used.

[0033] S102: After receiving the wake-up information, the control module sends a first start control signal to the audio device.

[0034] S103: After the audio device receives the first start control signal, it turns on the recording function to receive the user's voice information, and sends the user's voice information to the control module, so that the control module combines the user's voice information with preset voice information Perform voiceprint matching, and after the matching is successful, send an unlock command to the door lock device of the vehicle.

[0035] In one embodiment, after the audio device receives the first activation control signal, it turns on the recording function and outputs voice prompts to receive the user's voice information, and send the user's voice information to the control module, so that the control module sends the user The voice information is matched with the preset voice information. Among them, the voice prompt information, such as "please enter your instructions", "please enter your unlocking voice", "please start your performance" and so on. In other embodiments, the voice prompt information output by the audio device can be personalized by a control device (for example, a car machine, etc.).

[0036] In one embodiment, after receiving the user's voice information, the control module performs voiceprint matching between the user's voice information and preset voice information. Among them, the preset sound information in the control module may be one or more pieces of sound information (for example, voice, voice instructions, etc.) previously custom input by the user through the audio device, and the control module performs processing on one or more pieces of sound information input by the user. Processing to get the user’s voiceprint. Among them, the voiceprint is the sound wave spectrum that carries speech information (which can be displayed with electrical instruments), and the voiceprint is not only specific, but also relatively stable. Therefore, the voiceprint will not change the speaking voice deliberately because of the speaker. , Tone, intonation, etc., it has the same role as fingerprint identification (identification of individuals), so as long as the voiceprint in the voice information received by the control module is the same as the voiceprint in the preset voice information, the matching can be successful , The content expressed without the need for sound information is exactly the same as the content expressed by the preset sound information. Therefore, the unlocking provided by the first embodiment of the present invention uses voiceprint matching as a key unlocking element, and can accurately identify a specific user through the user's arbitrary voice, and realize the unlocking of the car door, thereby realizing the intelligence of keyless unlocking And character specificity.

[0037] In other embodiments, voiceprint matching is still used as the unlocking element, but at the same time, the content of the user's voice information received by the control module and the content of the preset voice information in the control module need to be compared to obtain similar values, and similar values Matching can only be successful within a certain range, so on the basis of voiceprint matching, fuzzy speech recognition and precise speech recognition can be set. Among them, the fuzzy voice recognition method, for example, the content of the preset voice message is "unlock", then when the content of the voice message received by the control module is "unlock", "open cable", "open shot" or "open speaking" , It can match successfully. Among them, the precise voice recognition method, for example, the content of the preset voice information is "unlock", then the matching can be successful only when the content of the voice information received by the control module is "unlock". Therefore, the voiceprint matching and the content (instruction) matching of the voice information are used as the unlocking elements, which improves the security of the unlocking method provided in the first embodiment of the present invention, and can prevent other people from using the recording of the owner (user) to record the vehicle. The door is unlocked.

[0038] S104: After receiving the unlocking command, the door lock device performs an unlocking action.

[0039] In the unlocking method provided in the first embodiment of the present invention, the vehicle sensor detects that the user is close to the car door, and then turns on the recording function to receive the user's voice information, thereby matching the voice information with the preset voice information in the control module. After the matching is successful, the door of the vehicle is unlocked. Therefore, the user (vehicle owner) does not need to use a key or terminal to unlock the door, and use the user's biological information (voiceprint and/or instructions in the sound information) as the unlocking medium, that is, the specific user's voice information. The lock can be unlocked and the safety of unlocking the vehicle is ensured. Therefore, the unlocking method provided by the embodiment of the present invention realizes a convenient, intelligent, and safe way of unlocking a vehicle, thereby satisfying increasingly higher product requirements of users.
