[0024] To address the problems existing in the aforementioned related technologies, this embodiment provides a vehicle unlocking method, device, system, and vehicle.

[0025] like Figure 1 As shown in the figure, an embodiment of the present invention provides a vehicle unlocking system, including: a sentry system 110, a power management module 120, a biometric identification module 130, a vehicle controller 140, a human-machine interface controller 150, and an alerting component 160. The sentry system 110, power management module 120, biometric identification module 130, vehicle controller 140, human-machine interface controller 150, and alerting component 160 are connected via a CAN bus.

[0026] In some embodiments, the sentry system 110 may include an environmental acquisition device 111 and a sentry system controller 112. The environmental acquisition device 111 is installed on the exterior of the vehicle and may be integrated into the B-pillar (the pillar between the front and rear doors), below the exterior rearview mirror, or in the triangular area of ​​the windows, providing clear and unobstructed monitoring of the positions of the areas to the sides and front of the vehicle. In one embodiment, multiple environmental acquisition devices 111 are required to work together to cover a 360° target area around the vehicle. The target area around the vehicle refers to a specific three-dimensional space surrounding the vehicle body, typically covering the sides and adjacent rear areas of the doors, and its extent is defined by the installation location and sensing capabilities of the environmental acquisition devices 111. In one embodiment, the environmental acquisition device 111 may be an image acquisition device (camera) or an ultrasonic radar (radar).

[0027] The Sentry Mode Controller 112 is typically installed inside the vehicle's driver's cabin. It can be a standalone controller component or a sub-control module within the vehicle controller 140 or the human-machine interface controller 150.

[0028] The power management module 120 can be directly connected to the battery to obtain main power.

[0029] The biometric module 130 can be a fingerprint recognition module, a palmprint recognition module, or other module used to identify user biometric information. In one embodiment, the biometric module 130 may include a palmprint recognition module, which can be installed in a location where the user's palm naturally rests, such as the handlebar area. It is connected to the power management module 120 via a controlled power supply line. In some embodiments, the palmprint recognition module may include a near-infrared image sensor (TOF) and a palmprint recognition module controller. The TOF actively emits invisible near-infrared light to illuminate the palm and then receives the light reflected back from the palm veins and palm print texture. The palmprint recognition module controller can obtain palmprint information (palmprint image) based on the emitted light. In addition, the palmprint recognition module controller may also include a processing chip (SOC), a control chip (EUC), and a storage unit. The processing chip is used to preprocess, extract features, and compare palmprint information. The storage unit is used to store a preset database containing at least one pre-stored palmprint feature. The control chip is used to connect with other components via I / O ports. In other embodiments, the palmprint recognition module may also be other optical sensors (RGB) to acquire palmprint images, and the processing flow is the same as described above, which will not be repeated here.

[0030] The vehicle controller 140 is used to control various components of the vehicle body. The vehicle controller 140 can be connected to the biometric module 130 via a CAN bus.

[0031] The human-machine controller 150 is used to control the human-machine interaction display screen of the vehicle.

[0032] In some embodiments, the vehicle unlocking system also includes a notification component 160, such as a speaker, for notifying the user by voice or other means when unlocking is complete.

[0033] Based on the above vehicle unlocking system, such as Figure 2 As shown, this embodiment of the invention also provides a vehicle unlocking method, including the following steps: Step 210: While the vehicle is locked and the sentry system 110 is in operation, use the sentry system 110 to identify whether there are target personnel in the target area around the vehicle.

[0034] In some embodiments, the environmental data acquisition device 111 allows the vehicle owner to remotely activate the sentry system or a similar security button via a smartphone application linked to the vehicle. This command is transmitted via the mobile network to the vehicle's onboard gateway, thereby activating the relevant control unit. In other embodiments, the vehicle can automatically trigger the system based on its own status or environmental awareness. For example, when the vehicle detects that the owner has left and locked the vehicle via its key or Bluetooth module, the system can automatically activate the sentry system according to the owner's preset settings in the vehicle's infotainment system.

[0035] During the operation of the sentry system 110, the environmental acquisition device 111 collects environmental information of the target area around the vehicle in order to identify whether there are target personnel in the target area.

[0036] In some embodiments, the environmental acquisition device 111 can be an image acquisition device, such as a camera, which continuously acquires real-time data of the target area around the vehicle and performs real-time identification of target personnel from the acquired images.

[0037] In other embodiments, the environmental acquisition device 111 can be an ultrasonic radar, which continuously emits ultrasonic signals to the target area around the vehicle. The ultrasonic signals are reflected back to the target area as ultrasonic echo signals, and the target personnel are identified in real time based on the ultrasonic echo signals.

[0038] In some embodiments, the target person can be a person within the target area around the vehicle, or a person within the target area around the vehicle who is performing certain target actions, such as reaching out or stopping.

[0039] Step 220: If the target person is detected, activate the biometric module 130.

[0040] Specifically, activating the biometric module 130 can be achieved by controlling the supply of power to the biometric module 130, or by waking the biometric module 130 from a low-power state to an available state. Since the biometric module 130 is in a non-powered or low-power state when the sentry system 110 does not detect the presence of a target person in the target area around the vehicle, and starts supplying power to or activating the biometric module 130 when the sentry system 110 detects the presence of a target person in the target area around the vehicle, the static power consumption of the vehicle can be significantly reduced.

[0041] Specifically, the power management module 120 is used for intelligent management of the power supply of various modules in the vehicle. After the owner leaves the vehicle, most of the vehicle's modules are usually in a dormant state, and some modules are only awakened to provide power when certain events are triggered. Therefore, in this embodiment, when the sentry system 110 detects the presence of a target person, it awakens the biometric module 130 and controls the power management module 120 to turn on the power to the biometric module 130.

[0042] Step 230: In response to the biometric module 130 collecting the user's current biometric information, the user's identity is identified based on the current biometric information.

[0043] Specifically, after power is supplied to the biometric module 130, the biometric module 130 immediately initiates its core biometric feature acquisition process. In some embodiments, for palmprint recognition, the built-in high-resolution near-infrared image sensor or optical sensor is first used to actively illuminate and scan the user's palm (usually placed in a designated sensing area on a car window or B-pillar). After acquiring clear palmprint information (palmprint image), the processing chip built into the biometric module 130 immediately runs a feature extraction algorithm to accurately analyze the unique and difficult-to-replicate biometric information such as the venous structure of the palmprint and the vascular distribution pattern of the palm veins, and digitizes it into a set of highly abstract and unique feature point data, thus obtaining the current palmprint features. In other embodiments, the processing chip built into the biometric module 130 can also extract the current palmprint features through a pre-trained neural network model, which is pre-trained on palmprint information under different environments.

[0044] Step 240: If the identity verification is successful, unlock the vehicle; otherwise, keep the vehicle locked.

[0045] Specifically, the biometric module 130 compares the real-time collected current biometric information with the pre-stored biometric information, and determines whether the user's identity verification is successful based on the comparison result.

[0046] Specifically, after the biometric module 130 confirms successful user identification, it sends an unlock command to the vehicle controller 140. In response to this unlock command, the vehicle controller 140 sends an unlock signal to the vehicle's locking / unlocking components, controlling the internal micro-motor or solenoid valve to perform the unlocking action, thus enabling the vehicle to be unlocked. Conversely, in some embodiments, if the biometric module 130 fails to confirm user identification, the vehicle controller 140 will not receive any unlock command, and the vehicle's locking / unlocking components will remain in their current state. In other embodiments, if the biometric module 130 fails to confirm user identification, the vehicle controller 140 will receive an "authentication failure" signal, and the vehicle's locking / unlocking components will remain in their current state. Vehicle unlocking includes at least one of the following: door unlocking, rearview mirror unfolding, vehicle infotainment screen illumination, and activation of the welcome function.

[0047] In this embodiment, during the operation of the sentry system, the system identifies whether a target person exists within the target area around the vehicle. If a target person is detected, the biometric module is activated. The sentry system prevents the biometric module from activating when no target person is present, thus reducing the vehicle's static power consumption. In response to the biometric module collecting the user's current biometric information, the system identifies the user based on this information. If the identification is successful, the vehicle is unlocked; otherwise, it remains locked. This provides a convenient and highly secure vehicle unlocking method that can be completed simply by reaching out when no key or mobile phone is available. This allows for vehicle unlocking in various scenarios, improving the user experience and reducing the vehicle's static power consumption through the operation of the sentry system.

[0048] Optionally, the sentry system 110 includes an image acquisition device, which is used to identify whether there are target personnel in the target area around the vehicle, such as... Figure 3 As shown, it includes the following steps: Step S310: Use the image acquisition device in the sentry system 110 to acquire environmental images of the target area around the vehicle.

[0049] Step S320: Identify whether the person to be identified exists in the environmental image.

[0050] Specifically, the image acquisition device has image processing capabilities. It first preprocesses the acquired environmental image (such as color correction and noise reduction) to optimize image quality. Then, it scans the environmental image using a target detection algorithm to quickly locate all candidate regions that may contain the person to be identified and generates initial bounding boxes. For these candidate regions, it further extracts their depth features or analyzes their pose key points and submits them to a classifier for accurate judgment, calculating the confidence level of their belonging to the "person to be identified" category. Finally, it removes overlapping false detections through post-processing (such as non-maximum suppression) and outputs detection results with precise location and confidence level, thereby completing the determination of whether the person to be identified exists and their location in the entire environmental image.

[0051] Step S330: If a person to be identified is detected, the current action of the person to be identified is analyzed.

[0052] Specifically, if a vehicle is parked in an area with many pedestrians, such as a parking area next to a main road, the biometric module 130 would be activated too frequently if it were to be activated every time a person to be identified was detected, which would not effectively reduce the power consumption of the vehicle's power supply system. Therefore, to address the above problem, this embodiment analyzes the current actions of the person to be identified after detection to determine the likelihood that they are the vehicle owner.

[0053] Step S340: If the current action is the target action, then it is determined that there are target personnel in the target area.

[0054] Specifically, the target action is a series of specific behavioral patterns that are pre-set by the car owner or learned by the system and have an identity orientation, such as stopping or reaching out.

[0055] In some embodiments, a preset behavior analysis algorithm is used to analyze the behavior of the region of the person to be identified in the image to determine the current action of the person to be identified. If the current action successfully matches the preset target action library, the current action of the person to be identified is determined to be the target action.

[0056] In this optional embodiment, the sentry system 110 collects environmental images of the target area around the vehicle, and identifies whether there is a person to be identified in the target area and whether the identified person is the target person, so as to accurately identify whether there is a target person in the target area and reduce the probability of misidentifying pedestrians.

[0057] Because the image acquisition device of Sentinel System 110 cannot acquire clear images in low ambient light conditions, it can detect the distance between moving objects and vehicles and the speed of moving objects within the target area based on the ultrasonic signals emitted and received by the ultrasonic radar to determine whether there are target personnel in the target area.

[0058] Optionally, when the sentry system 110 includes an image acquisition device and an ultrasonic radar, the sentry system 110 is used to identify whether there are target personnel in the target area around the vehicle, such as... Figure 4 As shown, it includes the following steps: Step S410: Use the ultrasonic radar of the sentry system 110 to send ultrasonic signals to the target area around the vehicle, and receive the ultrasonic echo signals returned after the ultrasonic signals are reflected by the target area.

[0059] Specifically, the ultrasonic radar sends ultrasonic signals to the target area around the vehicle. When the ultrasonic signals encounter objects (including people), they are reflected back, forming ultrasonic echo signals, which are received by the ultrasonic radar. By calculating the time difference between the transmitted and received signals, the distance and contour information of objects in the target area can be constructed in real time.

[0060] Step S420: Based on the ultrasonic echo signal, identify whether there is a target person in the target area.

[0061] Specifically, based on the received ultrasonic echo signals, the system can effectively distinguish between stationary obstacles and moving objects by analyzing the intensity and phase changes of the ultrasonic echo signals. Furthermore, by using information such as the distance and speed between the moving object and the vehicle, it can determine whether a target person exists.

[0062] In this optional embodiment, in scenarios such as poor ambient light, ultrasonic radar is used to transmit and receive radar waves to detect the distance and speed of moving objects in the target area around the vehicle, so as to accurately identify whether there are target personnel in the target area, and thus achieve sentry mode in various scenarios.

[0063] Optionally, the user is identified based on the current biometric information, including: obtaining a preset database containing at least one biometric information; if the current biometric information matches any biometric information in the preset database, the identification is deemed successful; otherwise, the identification is deemed unsuccessful.

[0064] Specifically, the preset database is a database that stores the biometric information of vehicle owners. When a vehicle owner first enters their biometric information, they will enter their own biometric information into the preset database.

[0065] In this optional embodiment, the collected current biometric information of the user is compared with the pre-entered biometric information in the preset database. If there is biometric information in the preset database that matches the currently collected current biometric information, it means that the user has previously entered their identity and the identity recognition is successful. If there is no biometric information in the preset database that matches the currently collected current biometric information, the identity recognition is determined to be unsuccessful.

[0066] Optionally, to better remind the user whether the vehicle has been successfully unlocked, embodiments of the present invention further include: If the identity verification is successful, the corresponding first reminder message will be output through the reminder component 160; otherwise, the corresponding second reminder message will be output through the reminder component 160.

[0067] In some embodiments, the notification component 160 can be a speaker. If the identity verification is successful, the speaker will play a voice message such as "Unlock successful"; otherwise, the speaker will play a voice message such as "Unlock failed".

[0068] In other embodiments, the reminder component 160 may also be other reminder components, such as a turn signal, which can output corresponding reminder information by flashing the turn signal.

[0069] The above describes the specific process for unlocking vehicles using biometric information identification while the sentry system 110 is running. For vehicles where the sentry system 110 is not activated, this embodiment of the invention also provides a vehicle unlocking method, such as... Figure 5 As shown, it includes the following steps: Step S510: When the vehicle is locked and the sentry system is not running, control the biometric module 130 to continue running.

[0070] Specifically, the biometric module 130 is activated after the vehicle is locked and remains operational while the vehicle is locked.

[0071] Step S520: In response to the biometric module 130 collecting the user's current biometric information, the user's identity is identified based on the current biometric information.

[0072] Step S530: If the identity verification is successful, the vehicle will be unlocked; otherwise, the vehicle will remain locked.

[0073] Specifically, when the sentry system 110 is not activated and only the biometric module 130 is activated, power will be directly supplied to the biometric module 130 without needing to identify whether there are target personnel in the target area around the vehicle.

[0074] It should be noted that the specific implementation methods of each step of the above method have been described in detail in the above embodiments, and will not be repeated here.

The biometric module 620 is activated if the target person is detected. The biometric identification module 630 is used to identify the user based on the current biometric information collected by the biometric identification module. The unlocking control module 640 is used to unlock the vehicle if the identity verification is successful, and otherwise keep the vehicle locked.
