[0030] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0031] The vehicle unlocking method, device, vehicle, and storage medium according to the embodiments of the present application will be described below with reference to the accompanying drawings. Regarding the single fingerprint or face recognition mentioned in the above background art, in some special environments (such as low temperature, rainy days, or insufficient light), it may not be accurately recognized or may fail, affecting the unlocking efficiency and security of the vehicle. The present application provides a vehicle unlocking method. In this method, after the UWB device signal of the user is recognized and the actual distance between the user and the vehicle is less than the first preset distance, the environmental data around the vehicle and the user image are collected, and the hand state of the user in the user image is recognized. The most suitable target authentication function for vehicle unlocking determined by different environmental data and the hand state of the user can avoid the inability to accurately authenticate the user's identity in some special environments, and at the same time, the appropriate target authentication function can be selected when the user's hand is inconvenient, improving the unlocking efficiency of the vehicle, enhancing the user's experience and convenience, and unlocking the vehicle by combining the UWB device authentication and the target function authentication method. The target authentication function is used to authenticate the user's identity, and the vehicle is unlocked after the authentication is passed, thereby improving the unlocking security of the vehicle. Thus, the problems in the related art that a single unlocking method may not be accurately recognized or may fail due to environmental influences, resulting in low unlocking efficiency and security of the vehicle, are solved.

[0032] Before describing the vehicle unlocking method of the present application, the vehicle unlocking methods in the related art (as shown in Table 1, Table 1 is the unlocking solution in the related art) and the functional modules and specific structures for implementing the solution of the embodiments of the present application will be introduced first.

[0033] Table 1

[0034]

[0035] The modules and hardware parts involved in the embodiments of the present application include the existing body function modules and the function modules integrated on the outer trim panel of the B-pillar of the vehicle. Among them, the structure of the outer trim panel of the B-pillar is as Figure 1 shown, including the outer panel, inner panel, sealing foam, plastic buckle, and integrated function module of the outer trim panel of the B-pillar.

[0036] Among them, the function modules integrated on the outer trim panel of the B-pillar include the image and face recognition module, the palm vein recognition module, and the voice interaction module.

[0037] 1. Image and face recognition module: Used for long-distance image recognition to locate the person carrying the UWB key, recognize the state of their hands and whether they are carrying items; used for close-range face recognition, preferably enabled in specific situations (such as when holding something in the hand).

[0038] 2. Palm vein recognition module: Used to recognize the palm vein of the user, especially as a backup recognition method when the user's hand is blocked or the weather conditions are bad.

[0039] Palm vein recognition technology uses near-infrared light to penetrate the palm and detect the unique pattern of the vein blood vessels for identity verification. Different from traditional fingerprint recognition and face recognition, palm vein technology can achieve non-contact and non-invasive measurement. As long as there is blood flow in the vein, the collection is not affected by the skin condition. The recognition accuracy is as follows: FAR (False Acceptance Rate) < 0.00001%, FRR (False Rejection Rate) < 0.01%, and the recognition speed < 0.3s. This method has a high level of anti-counterfeiting ability because the vein pattern is located inside the skin and is difficult to replicate.

[0040] 3. Voice interaction module: Conducts voice interaction with the user through a speaker to provide prompts and feedback.

[0041] The existing body function modules include a UWB key module and an environmental sensor module. Among them,

[0042] 1. UWB key module: Perceives the user's UWB key through ultra-wideband wireless communication technology and triggers subsequent recognition operations.

[0043] UWB technology is gradually being applied in automotive digital key systems, providing high-precision positioning and anti-theft protection. UWB digital keys have the characteristics of precise positioning and active welcome functions.

[0044] 2. Environmental sensor module: Includes temperature sensors, rain sensors, light sensors, etc., which are used to detect environmental changes and provide a basis for decision-making.

[0045] The inner and outer panels of the B-pillar exterior trim are bonded with structural adhesive. The image and face recognition module, voice interaction module, and palm vein recognition module are integrated on the trim through structural adhesive or screw BOSS columns or low-pressure injection molding of the inner and outer panels. The trim is installed on the side body or the outer door panel through snaps and locating pins. Different function modules are interconnected through CAN communication and work together. The specific communication connection is as Figure 2 shown to achieve intelligent unlocking and user interaction.

[0046] Specifically, Figure 3 is a schematic flow chart of a vehicle unlocking method provided by an embodiment of the present application.

[0047] As Figure 3 shown, the vehicle unlocking method includes the following steps:

[0048] In step S101, when the UWB device signal of the user is recognized, the actual distance between the user and the vehicle is detected.

[0049] Among them, the UWB device can be a vehicle key. The UWB device signal can be detected by the UWB key recognition module. The vehicle and the UWB device can establish a connection through BLE (Bluetooth Low Energy). The UWB key recognition module can capture the UWB device signal through the UWB anchor.

[0050] In step S102, if the actual distance is less than the first preset distance, the environmental data around the vehicle and the user image are collected.

[0051] Among them, the first preset distance can be set according to specific circumstances, and no specific limitation is made here. For example, it is set to 10m. The environmental data and the user image can be collected by the image and face recognition module.

[0052] It can be understood that in the embodiment of the present application, when the actual distance between the user and the vehicle is less than the first preset distance, the environmental data around the vehicle and the user image can be collected for subsequent execution of the vehicle unlocking operation.

[0053] In step S103, the hand state of the user in the user image is recognized, the target authentication function required for vehicle unlocking is determined according to the environmental data and the hand state, the user is authenticated, and the vehicle is unlocked after the authentication is passed.

[0054] Among them, the target authentication function includes the palm vein recognition function and the face recognition function. The hand state includes the first state and the second state. The first state is that the hand holds an item, and the second state is that the hand does not hold an item.

[0055] It can be understood that in the embodiment of the present application, the target authentication function required for vehicle unlocking can be determined according to the environmental data and the hand state, and the user is authenticated. After the authentication is passed, the vehicle is unlocked. The vehicle is unlocked by combining the UWB device authentication and the target function authentication methods, improving the unlocking security of the vehicle. And the target authentication function is the most suitable authentication function determined based on different environmental conditions and the user's hand state, which can be flexibly switched according to the scenario, avoiding the inability to accurately authenticate the user's identity in some special environments (such as low temperature, rainy days or insufficient light), and at the same time, the appropriate authentication function can be selected when the user's hand is inconvenient, improving the unlocking efficiency of the vehicle and enhancing the user's usage experience and convenience.

[0056] In the embodiment of the present application, determining the target authentication function required for vehicle unlocking according to the environmental data and the hand state includes: if the hand state is the first state, the target authentication function is the face recognition function; if the hand state is the second state, the target authentication function required for vehicle unlocking is determined according to the environmental data.

[0057] Wherein, the first state is that the hand holds an item, and the second state is that the hand does not hold an item.

[0058] It can be understood that in the embodiment of the present application, when the hand state of the user is the first state, that is, when the user's hand holds an item, since it is inconvenient for the user to use the palm vein unlocking function, the target authentication function is the face recognition function. When the hand state of the user is the second state, the target authentication function required for vehicle unlocking can be determined according to the environmental data.

[0059] In the embodiment of the present application, determining the target authentication function required for vehicle unlocking according to the environmental data includes: identifying the current temperature and the current visibility in the environmental data; determining the target authentication function according to at least one of the current temperature and the current visibility.

[0060] Wherein, the current temperature can be obtained through vehicle networking information or a temperature sensor; the current visibility can be obtained through vehicle networking information or a 360 parking radar, a panoramic camera, or a light sensor. The visibility can be affected by the weather and the lighting environment of the parking position.

[0061] It can be understood that the embodiment of the present application can determine the target authentication function according to at least one of the current temperature and the current visibility, as follows.

[0062] In the embodiment of the present application, determining the target authentication function according to at least one of the current temperature and the current visibility includes: if the current temperature is less than the preset temperature, the target authentication function is the face recognition function; if the current temperature is greater than or equal to the preset temperature, a selection prompt is generated, and the target authentication function is determined to be the palm vein recognition function or the face recognition function according to the user's selection.

[0063] Wherein, the preset temperature can be set according to the specific situation, and no specific limitation is made here. For example, it is 10°C.

[0064] It can be understood that in the embodiment of the present application, when the current temperature is less than the preset temperature, the target authentication function is the face recognition function, thereby avoiding the need for the user to expose their hand in the air when using the palm vein recognition function, improving the user experience. When the current temperature is greater than or equal to the preset temperature, a selection prompt can be generated, and the target authentication function is determined to be the palm vein recognition function or the face recognition function according to the user's selection, fully respecting the user's intention.

[0065] In the embodiment of the present application, determining the target authentication function according to at least one of the current temperature and the current visibility includes: if the current visibility is less than the preset visibility, the target authentication function is the palm vein recognition function; if the current visibility is greater than or equal to the preset visibility, a selection prompt is generated, and the target authentication function is determined to be the palm vein recognition function or the face recognition function according to the user's selection.

[0066] Among them, the preset visibility can be calibrated in advance according to specific situations, and no specific limitation is made here. For example, it is 5m.

[0067] It can be understood that in the embodiment of the present application, when the current visibility is less than the preset visibility, in order to avoid the situation that the face recognition function may be unclear or invalid at this time, the target authentication function is the palm vein recognition function. When the current visibility is greater than or equal to the preset visibility, a selection prompt is generated, and the target authentication function is determined to be the palm vein recognition function or the face recognition function according to the user's selection, fully respecting the user's intention.

[0068] In the embodiment of the present application, determining the target authentication function according to at least one of the current temperature and the current visibility includes: if the current temperature is less than the preset temperature and the current visibility is greater than or equal to the preset visibility, the target authentication function is the face recognition function; if the current visibility is less than the preset visibility and the current temperature is greater than or equal to the preset temperature, the target authentication function is the palm vein recognition function; if the current temperature is less than the preset temperature and the current visibility is less than the preset visibility, or if the current visibility is greater than or equal to the preset visibility and the current temperature is greater than or equal to the preset temperature, a selection prompt is generated, and the target authentication function is determined to be the palm vein recognition function or the face recognition function according to the user's selection.

[0069] It can be understood that in the embodiment of the present application, when the current temperature is less than the preset temperature and the current visibility is greater than or equal to the preset visibility, it indicates that the temperature is low and the visibility is high at this time, and the target authentication function is the face recognition function; when the current visibility is less than the preset visibility and the current temperature is greater than or equal to the preset temperature, it indicates that the temperature is high and the visibility is high at this time, and the target authentication function is the palm vein recognition function; when the current temperature is less than the preset temperature and the current visibility is less than the preset visibility, or if the current visibility is greater than or equal to the preset visibility and the current temperature is greater than or equal to the preset temperature, it indicates that both the temperature and the visibility are high, a selection prompt is generated, and the target authentication function is determined to be the palm vein recognition function or the face recognition function according to the user's selection.

[0070] In the embodiment of the present application, before authenticating the user's identity, it includes: when the actual distance is less than the second preset distance, the target authentication function of the vehicle is started, where the second preset distance is less than the first preset distance.

[0071] Among them, the second preset distance can be set according to specific situations, and no specific limitation is made specifically. The second preset distance is the critical distance for enabling the target authentication function. For example, it is set to 3m or 4m.

[0072] It can be understood that in the embodiments of the present application, when the actual distance is less than the second preset distance, the target authentication function of the vehicle can be activated, avoiding long-term standby of the hardware of the palm vein recognition function and the face recognition function of the vehicle, resulting in unnecessary power consumption, and thus saving energy consumption.

[0073] In addition, it should be noted that in the embodiments of the present application, when the hand state of the user is detected to be the first state, it can be asked by voice whether to open the trunk, and when the user answers yes, an instruction is automatically sent to the vehicle computer to operate and open the trunk, improving the user's driving experience. And in the scenario where the UWB device is forgotten to be carried, the palm vein recognition module can be awakened by the micro switch to start identity verification and unlocking, so that it is possible to completely get rid of the digital key and the physical key, which is especially suitable for groups such as the elderly and scenarios such as fitness.

[0074] In the embodiments of the present application, when the vehicle is unlocked, the air conditioner can also be turned on and adjusted to the target temperature and / or the seat can be adjusted to the target angle to improve the user's driving experience. Among them, the target temperature can be the temperature during the previous use of the vehicle, and the target angle can be the seat angle commonly used by the user.

[0075] In summary, for the vehicle unlocking method in the embodiments of the present application, through multi-modal technology interaction, when the vehicle owner approaches the vehicle with the UWB key, the UWB key module senses the presence of the vehicle owner through the ultra-wideband wireless communication technology and triggers the image recognition system of the vehicle. The camera module in the image and face recognition module starts to perform human detection and analyze the hand state. If the user is holding an object, the face recognition module is preferentially activated; if the hands are free, the face recognition or palm vein recognition method is intelligently selected according to environmental conditions (such as temperature, light, etc.). After successful recognition, the user is confirmed to operate through the voice interaction module, such as opening the trunk, etc., and the comfort settings in the vehicle are adjusted according to the user's needs, so as to dynamically select the preferred identity recognition method and improve the user experience through voice interaction, realizing the multi-scenario adaptation ability, dual identity verification and passive comfort adjustment function, and improving the safety and use convenience of the vehicle.

[0076] The vehicle unlocking method in the embodiments of the present application will be described below through specific application scenarios. As shown in Table 2, Table 2 shows the working mechanisms and technical effects of various modules in various application scenarios.
