Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile technology, and in particular to a multi-level identity authentication system applied to a vehicle and an automobile. BACKGROUND

[0002] An automobile itself is a kind of property, which has asset value and use value, so the owner of the automobile generally only allows specific personnel to use the automobile. The current related automobile technology generally applies intelligent identity authentication technology, which can perform identity authentication on personnel who approach the automobile or attempt to operate the automobile, and only in the case of passing the authentication, the use permission of the automobile is opened to the personnel. However, the current identity authentication technology applied to the automobile is relatively single, and has defects such as being vulnerable to photo, video and other non-living body cheating means. SUMMARY

[0003] In view of at least one of the above technical problems, the purpose of the present application is to provide a multi-level identity authentication system applied to a vehicle and an automobile.

[0006] Further, the configuration of the activation state of each of the unlocking items according to each of the identity recognition results comprises: Under a default condition, it is determined to execute a same-level configuration mode. In the same-level configuration mode, for any of the identity recognition results, when the identity recognition result is a recognition success, the unlocking item corresponding to the same processing level of the identity recognition result is configured as activated, otherwise, when the identity recognition result is a recognition failure, the unlocking item corresponding to the same processing level of the identity recognition result is configured as inactivated, and it is determined that a first trigger condition is met.

[0007] Further, the configuration of the activation state of each of the unlocking items according to each of the identity recognition results comprises: When the first trigger condition is met, it is determined to execute a downward cross-level configuration mode. In the downward cross-level configuration mode, for any of the identity recognition results, when the identity recognition result is a recognition success, the unlocking item corresponding to the same processing level of the identity recognition result is configured as activated, otherwise, when the identity recognition result is a recognition failure, at least one higher-level processing level identity recognition result corresponding to the identity recognition result is obtained to obtain a first total result, when the first total result meets a threshold condition, the unlocking item corresponding to the same processing level of the identity recognition result is configured as activated and marked, otherwise, when the first total result does not meet the threshold condition, the unlocking item corresponding to the same processing level of the identity recognition result is configured as inactivated.

[0008] Further, the configuration of the activation state of each of the unlocking items according to each of the identity recognition results comprises: In the downward cross-level configuration mode, when the unlocking item corresponding to the lowest-level processing level is inactivated, the detection range of the identity recognition module corresponding to the highest-level processing level is limited.

[0009] Further, the configuration of the activation state of each of the unlocking items according to each of the identity recognition results comprises: In the downward cross-level configuration mode, the unlocking item marked is configured with a limit of an activation validity period, and it is determined that a second trigger condition is met; when the activation validity period expires, the unlocking item is converted to be configured as inactivated.

[0010] Further, the configuration of the activation state of each of the unlocking items according to each of the identity recognition results comprises: When the activation validity period limit of the unlocked item is marked, a prompt information is generated; the prompt information is used to prompt the activation validity period; The man-machine interaction module is called to display the prompt information.

[0011] Further, the activation state of each unlocked item is configured according to each identity recognition result, including: When the second trigger condition is met, it is determined to execute an upward cross-level configuration mode; In the upward cross-level configuration mode, for the unlocked item configured with the activation validity period, at least one identity recognition result of a lower processing level corresponding to the unlocked item is obtained, and a second total result is obtained by totalizing the at least one identity recognition result; when the second total result meets a threshold condition, the activation validity period limit of the unlocked item is revoked; when the second total result does not meet the threshold condition, the activation validity period limit of the unlocked item is maintained.

[0012] Further, each identity recognition module performs identity detection based on different detection principles.

[0013] On the other hand, the embodiment of the application also includes a car, and the car includes the multi-level identity authentication system applied to the vehicle in the embodiment.

DETAILED DESCRIPTION

[0016] Terminology: DMS: Driver Monitoring System, a driver monitoring system that can be used to monitor the alertness of the driver in the vehicle. This system not only performs driver identification, but also monitors the alertness and detects early signs of drowsiness, which is crucial for ensuring the safety of vehicle driving. CAN: Controller Area Network, a controller area network bus, which is a serial communication protocol bus for real-time applications, used for communication between various elements in the vehicle.

[0017] In this embodiment, a multi-level identity authentication system applied to a vehicle is provided, which has a structure as shown in Figure 1 Referring to Figure 1 , the multi-level identity authentication system applied to the vehicle includes a control module and a plurality of identity recognition modules. In this embodiment, each identity recognition module can perform identity detection based on different detection principles. For example, in this embodiment, the plurality of identity recognition modules can be a digital key module, an outside-around-view camera, a seat pressure sensor, and an in-vehicle DMS camera.

[0018] Among them, the identity recognition module 1 (digital key module) adopts the Bluetooth digital key integrated in the smart phone, supports the Bluetooth 5.0 protocol, establishes communication with the digital key by detecting the digital key carried by the user, exchanges data, verifies the data, and determines the identity of the user carrying the digital key when the verification is passed; the identity recognition module 2 (out-of-vehicle surround view camera) is a front-view surround view camera of the vehicle, with a resolution of 1080P and a frame rate of 30fps, and has a wide dynamic range. Visible light is used to shoot images of the user's face and body, and a face recognition algorithm or a body shape recognition algorithm is used to achieve coarse-scale recognition of the user's identity; the identity recognition module 3 (seat pressure sensor) detects the pressure on the seat and compares it with the preset user weight. If the detected pressure matches the preset user weight, it is determined that the user's identity has been detected, or if the detected pressure is greater than the pressure threshold (for example, 500N), it is determined that the user's identity has been detected; the identity recognition module 4 (in-vehicle DMS camera) is a near-infrared 3D camera based on TOF technology, which can output 3D images with a depth accuracy of ±1% and an infrared wavelength of 940nm. The face features of the user are detected by infrared rays, and compared with the preset user face features. When the comparison is passed, it is determined that the user's identity has been detected.

[0019] In this embodiment, the control module is a vehicle central control ECU, which adopts a multi-core processor and supports real-time data processing. An encrypted flash memory is arranged inside the control module as a storage module, with a capacity of 16GB, which can store the owner's face feature template and system programs.

[0020] In this embodiment, each identity recognition module has its own detection range. For example, the detection range of the identity recognition module 1 (digital key module) can be a certain radius (for example, 10m) around the vehicle; the detection range of the identity recognition module 2 (out-of-vehicle surround view camera) can be a certain distance (for example, 2m) outward from the driver's seat of the vehicle; the detection range of the identity recognition module 3 (seat pressure sensor) can be the surface of the seat; and the detection range of the identity recognition module 4 (in-vehicle DMS camera) can be the driver's seat of the vehicle. Each identity recognition module performs identity detection in its respective detection range, i.e. only when a person enters the detection range of an identity recognition module, can the identity recognition module detect the identity of the person, otherwise it cannot detect the identity of the person. Moreover, the detection range of each identity recognition module is related not only to the real space determined by its installation position, but also to the working state of the identity recognition module. For example, if the identity recognition module 3 (seat pressure sensor) is not activated (unlocked), it is equivalent to the identity recognition module 3 (seat pressure sensor) not having a detection range at this time, i.e. even if a person sits on the driver's seat, he or she does not enter the detection range of the identity recognition module 3 (seat pressure sensor).

[0021] In this embodiment, each identity recognition module can be a hardware module specially designed for the multi-level identity authentication system applied to the vehicle, or can reuse the identity recognition module already provided in the vehicle, i.e., the identity recognition module can be used by other systems in the same vehicle in addition to the multi-level identity authentication system applied to the vehicle.

[0022] In this embodiment, the control module can be connected with each identity recognition module through a CAN bus. Each identity recognition module sends the identity recognition result detected by itself to the control module in real time. Specifically, the content of the identity recognition result detected by the identity recognition module can only include "recognition success (indicating that the same identity feature as the reserved identity information is recognized, and the user being recognized is a legal user)" or "recognition failure (indicating that the identity feature recognized is not the same as the reserved identity information, and the user being recognized is an illegal user)", or can be as shown in Table 1, including specific parameters related to the identity recognition process.

[0023] Table 1 Content of identity recognition result

[0024] In this embodiment, on the basis of the system shown in Figure 1 , the control module can perform the multi-level identity authentication method applied to the vehicle. Referring to Figure 2 , the multi-level identity authentication method applied to the vehicle includes the following steps: S1. configuring a plurality of processing levels; S2. configuring each identity recognition module to correspond to a corresponding processing level; S3. configuring a corresponding unlocking item for each processing level; S4. acquiring the identity recognition result of each identity recognition module in real time; S5. configuring the activation state of each unlocking item according to the identity recognition result.

[0025] The principles of steps S1-S4 are shown in Figure 3 . Referring to Figure 3 , in step S1, the control module configures a plurality of processing levels, i.e., processing level 1, processing level 2, processing level 3, and processing level 4. The levels corresponding to these processing levels are arranged in order from high to low, for example, the level of processing level 1 is higher than that of processing level 2. Specifically, the number of all processing levels can be the same as the number of all identity recognition modules, for example Figure 3 , four identity recognition modules are provided, and four processing levels are correspondingly provided.

[0026] Referring to Figure 3, in step S2, the control module configures each identity recognition module to correspond to a respective processing level. Specifically, the control module can perform the following steps: S201. Order each identity recognition module according to an order of reachability of a detection range of each identity recognition module by the user; S202. Assign each identity recognition module to a processing level in descending order according to the order of each identity recognition module.

[0027] In step 201, the control module assumes that all vehicle components have been unlocked, and the user can freely reach any position on the vehicle, and determines the order of reachability of a detection range of each identity recognition module by the user, i.e., the order in which the user enters the detection range of each identity recognition module, in the process of the user approaching the vehicle from outside the vehicle, entering the vehicle, using or driving the vehicle. For example, in this embodiment, in the process of the user approaching the vehicle from outside the vehicle, entering the vehicle, using or driving the vehicle, the user first enters the detection range of identity recognition module 1 (digital key module), then enters the detection range of identity recognition module 2 (outdoor surround view camera), then enters the detection range of identity recognition module 3 (seat pressure sensor), and finally enters the detection range of identity recognition module 4 (in-vehicle DMS camera), i.e., the order of reachability of a detection range of each identity recognition module by the user is identity recognition module 1 (digital key module), identity recognition module 2 (outdoor surround view camera), identity recognition module 3 (seat pressure sensor), and identity recognition module 4 (in-vehicle DMS camera).

[0028] In step S202, referring to Figure 3 , according to the order determined in step S201, identity recognition module 1 (digital key module) ranked first is configured as the highest processing level 1, and based on the same principle, identity recognition module 2 (outdoor surround view camera), identity recognition module 3 (seat pressure sensor), and identity recognition module 4 (in-vehicle DMS camera) are respectively configured as processing level 2, processing level 3, and processing level 4.

[0029] In step S3, the control module configures each processing level with a respective unlocking item. Referring to Figure 3, each unlocking item corresponds to one or more vehicle components, the control module can configure an unlocking item as "activated" or "non-activated", if an unlocking item is "activated", the vehicle component corresponding to the unlocking item will be unlocked, on the contrary, if an unlocking item is "non-activated", the vehicle component corresponding to the unlocking item will be locked. For example, if the unlocking item 2 is "activated", the vehicle door corresponding to the unlocking item 2 will be unlocked, so as to be opened automatically or manually, on the contrary, if the unlocking item 2 is "non-activated", the vehicle door corresponding to the unlocking item 2 will be locked, so as to be unable to be opened.

[0030] In the embodiment, when the control module executes step S3, the control module can dynamically adjust the vehicle components corresponding to each unlocking item, so as to make each unlocking item have the relationship with each processing level, that is, when an unlocking item is activated, the function of the corresponding vehicle component is unlocked, so as to make the detection range of the lower-level identity recognition module accessible to the position of the user of the vehicle.

[0031] For example, referring to Figure 3 , the vehicle component corresponding to the unlocking item 1 includes the identity recognition module 2 (the outside-viewing camera) corresponding to the lower-level processing level (processing level 2) itself, if the unlocking item 1 is activated, the identity recognition module 2 (the outside-viewing camera) will be unlocked, so as to make the detection range of the lower-level identity recognition module 2 (the outside-viewing camera) accessible to the position of the user of the vehicle, that is, the user of the vehicle can enter the detection range of the lower-level identity recognition module 2 (the outside-viewing camera), so as to be detected by the identity recognition module 2 (the outside-viewing camera); on the contrary, if the unlocking item 1 is "non-activated", the identity recognition module 2 (the outside-viewing camera) will be locked, so as to make the identity recognition module 2 (the outside-viewing camera) equivalent to not having the detection range, and thus not having the position accessibility to the user of the vehicle.

[0032] For example, referring to Figure 3 , the vehicle component corresponding to the unlocking item 2 does not include the identity recognition module 3 (the seat pressure sensor) corresponding to the lower-level processing level (for example, processing level 3) itself, if the unlocking item 2 is activated, the vehicle door and other vehicle components will be unlocked, so as to make the user open the door and enter the car, so as to enter the detection range of the identity recognition module 3 (the seat pressure sensor), so as to make the detection range of the lower-level identity recognition module 3 (the seat pressure sensor) accessible to the position of the user of the vehicle, so as to be detected by the identity recognition module 3 (the seat pressure sensor).

[0033] In step S4, the control module acquires the identity recognition results of each identity recognition module (those that have been activated and whose functions have not been locked) in real time. Each identity recognition result can be the detailed information shown in Table 1.

[0034] In this embodiment, when the control module executes step S5, which is to configure the activation status of each unlocking item based on the identification results, it can specifically perform the following steps: S501. Under the default conditions, the sibling configuration mode is determined to be executed; S502. In the same-level configuration mode, for any identity recognition result, if the identity recognition result is successful, the unlocking item corresponding to the same processing level of the identity recognition result is configured as active; otherwise, if the identity recognition result is unsuccessful, the unlocking item corresponding to the same processing level of the identity recognition result is configured as inactive, and it is determined that the first triggering condition is met.

[0035] In this embodiment, the principle of steps S501-S502 is as follows: Figure 4 As shown.

[0036] Specifically, the default condition in step S501 can refer to any situation where events such as "determining that the first trigger condition is met" or "determining that the second trigger condition is met" do not occur, that is, the default execution of the same level configuration mode.

[0037] Reference Figure 4 A user carrying a digital key approaches a car equipped with a multi-level authentication system from outside the vehicle. Initially, only the detection range of the identity recognition module 1 (digital key module) is accessible to the user; therefore, only the identity recognition module 1 (digital key module) can detect the user and obtain the corresponding identity verification result.

[0038] Reference Figure 4, in step S502, if the identity recognition module 1 (digital key module) detects that "the Bluetooth signal strength containing the key is greater than or equal to -60dBm", the identity recognition result of the identity recognition module 1 (digital key module) is "recognition success", and the control module configures the unlocking item 1 to which the identity recognition module 1 (digital key module) belongs to the processing level 1 as "activated", so that the vehicle-mounted component corresponding to the processing level 1, i.e. the identity recognition module 2 (out-of-vehicle surround view camera), is unlocked, and the detection range of the identity recognition module 2 (out-of-vehicle surround view camera) has position accessibility to the user; then the user can walk to the side of the driver's seat outside the vehicle window, and the identity recognition module 2 (out-of-vehicle surround view camera) collects the face image of the user and performs face recognition, analyzes the dynamic characteristics of the face (such as blinking action) by using the optical flow method, and if the effective dynamic characteristics identical to the reserved user characteristics are detected, the identity recognition module 2 (out-of-vehicle surround view camera) sends the identity recognition result with the content of "recognition success" to the control module, and the control module configures the unlocking item 2 to which the identity recognition module 2 (out-of-vehicle surround view camera) belongs to the processing level 2 as "activated", so that the vehicle-mounted component corresponding to the processing level 2, i.e. the door, window and trunk, is unlocked, and the user can open the door and enter the vehicle, so that the detection range of the identity recognition module 3 (seat pressure sensor) has position accessibility to the user; then the user can enter the vehicle and sit on the driver's seat, so that the identity recognition module 3 (seat pressure sensor) detects the pressure, and assuming that the pressure detected by the identity recognition module 3 (seat pressure sensor) is inconsistent with the reserved user weight, the control module can call the human-computer interaction module to display "authentication failure, please adjust the sitting posture and sit down again", so that the identity recognition module 3 (seat pressure sensor) detects the pressure again, and assuming that the pressure repeatedly detected by the identity recognition module 3 (seat pressure sensor) for multiple times (such as 3 times) is inconsistent with the reserved user weight, the identity recognition module 3 (seat pressure sensor) sends the identity recognition result with the content of "recognition failure" to the control module, and the control module configures the unlocking item 3 to which the identity recognition module 3 (seat pressure sensor) belongs to the processing level 3 as "non-activated", so that the vehicle-mounted component corresponding to the processing level 3, i.e. the identity recognition module 4 (in-vehicle DMS camera), is locked, which is equivalent to making the identity recognition module 4 (in-vehicle DMS camera) not having a detection range, and thus the detection range of the identity recognition module 4 (in-vehicle DMS camera) does not have position accessibility to the user, and the identity recognition module 4 (in-vehicle DMS camera) cannot output the identity recognition result with the content of "recognition success" to unlock other vehicle-mounted components corresponding to the unlocking item 4, so that the vehicle-mounted components that can be used or operated by the user are limited to Figure 3The unlocking item 1 and the unlocking item 2 in the first unlocking item configuration correspond to the vehicle components, and the unlocking item 3 and the unlocking item 4 correspond to more vehicle components, such as the power system of the vehicle.

[0039] In this embodiment, by executing steps S501-S502, the peer configuration mode under the default condition can be realized, and in this mode, the multi-level collaborative identity authentication of multiple identity recognition modules can be realized; for example, referring to Figure 3 , the processing level 1 corresponds to the identity authentication detection phase based on the identity recognition module 1 (digital key module), and only when this phase is passed, the function of unlocking the corresponding part of the vehicle components is enabled, and the processing level 2 is entered; the processing level 2 corresponds to the identity authentication detection phase based on the identity recognition module 2 (outdoor surround view camera), and only when this phase is passed, the function of unlocking the corresponding part of the vehicle components is enabled, and the processing level 3 is entered; the processing level 3 corresponds to the identity authentication detection phase based on the identity recognition module 3 (seat pressure sensor), and only when this phase is passed, the function of unlocking the corresponding part of the vehicle components is enabled, and the processing level 4 is entered; the processing level 4 corresponds to the identity authentication detection phase based on the identity recognition module 4 (in-vehicle DMS camera), and only when this phase is passed, the function of unlocking the remaining vehicle components is enabled; therefore, by executing the peer configuration mode, multiple identity recognition modules can be called in levels, and the respective identity recognition detection of the multiple identity recognition modules is fully utilized to form multiple safeguards; specifically, the lower the processing level of the vehicle components, the more identity recognition modules are needed to detect the identity recognition result of "recognition success" to unlock the function, and the higher the processing level of the vehicle components, the earlier the function is unlocked, thereby achieving a balance between security and convenience.

[0040] In this embodiment, by executing steps S501-S502, if the situation shown in Figure 4 occurs, that is, when the peer configuration mode is executed, an identity recognition result with the content of "recognition failure" occurs, so that the unlocking item corresponding to the same processing level is configured as "non-activated", then the control module determines that the first trigger condition is met, and step S503-S504 is executed.

[0041] In this embodiment, when the control module executes step S5, that is, configures the activation state of each unlocking item according to each identity recognition result, the following steps can be executed: S503. When the first trigger condition is met, determine to execute the down-level configuration mode; S504. In the downward cross-level configuration mode, for any identity recognition result, when the identity recognition result is a successful recognition, the unlocking item corresponding to the same processing level of the identity recognition result is configured as active, otherwise, when the identity recognition result is a failed recognition, at least one higher-level identity recognition result corresponding to the identity recognition result is obtained to obtain a first total result, when the first total result meets a threshold condition, the unlocking item corresponding to the same processing level of the identity recognition result is configured as active and marked, otherwise, when the first total result does not meet the threshold condition, the unlocking item corresponding to the same processing level of the identity recognition result is configured as inactive.

[0042] In this embodiment, the principles of steps S503-S504 are as shown in Figure 5

[0043] In step S504, for the identity recognition result with the content of "successful recognition", for example Figure 5 the identity recognition result detected by the identity recognition module 1 (digital key module) and the identity recognition module 2 (out-of-vehicle surround view camera) in the embodiment, the unlocking item corresponding to the same processing level of the identity recognition result is configured as "active" as in the same-level configuration mode.

[0044] In step S504, for the identity recognition result with the content of "failed recognition" itself, for example Figure 5 the identity recognition result detected by the identity recognition module 3 (seat pressure sensor) in the embodiment, unlike the same-level configuration mode, the unlocking item corresponding to the same processing level of the identity recognition result is not directly configured as "inactive", but at least one higher-level identity recognition result corresponding to the identity recognition result is selected to be totalized to obtain a first total result. For example, for the identity recognition result of the seat pressure sensor, the identity recognition result of the seat pressure sensor is totalized with the identity recognition result of the seat pressure sensor and the identity recognition result of the seat pressure sensor, and the first total result is obtained. Figure 5 ​The identity recognition module 3 (seat pressure sensor) whose identity recognition result is "recognition failure" is identified, and the identity recognition result of the corresponding higher processing level includes the identity recognition result detected by the identity recognition module 1 (digital key module) and the identity recognition module 2 (outward-looking surround view camera), which have the format shown in Table 1, i.e., including "feature comparison similarity of the one detection obtaining the final result of recognition success", "detection time length consumed to obtain the final result", and "number of repeated detections in the case of initial non-recognition success and final result of recognition success". In this embodiment, in the case of selecting only one identity recognition result of the higher processing level, the first summed result is the identity recognition result of the higher processing level itself; in the case of selecting multiple identity recognition results of the higher processing level, the same type of addable parameter items of the multiple identity recognition results can be added to obtain the first summed result. For example, the "number of repeated detections in the case of initial non-recognition success and final result of recognition success" in the identity recognition results detected by the identity recognition module 1 (digital key module) and the identity recognition module 2 (outward-looking surround view camera) can be added to obtain data with the meaning of "total number of repeated detections of the identity recognition module 1 (digital key module) and the identity recognition module 2 (outward-looking surround view camera)", as the first summed result.

[0045] In step S504, a threshold condition for judging the size of the first summed result can be set. For example, a repeated detection number threshold (for example, 10 times) can be set. When the first summed result is less than the repeated detection number threshold, it is determined that the first summed result is small, the threshold condition is satisfied, and the identity recognition result of the identity recognition module 3 (seat pressure sensor) itself, i.e., the identity recognition result detected by the identity recognition module 3 (seat pressure sensor), is configured as "activated" and marked for the unlocking item 3 of the same processing level 3. Conversely, if the first summed result is greater than the repeated detection number threshold, it is determined that the first summed result is large, the threshold condition is not satisfied, and the identity recognition result is still configured as "non-activated" for the unlocking item of the same processing level.

[0046] In this embodiment, the principle of performing step S504 is that, with reference to Figure 5 For the identity recognition result itself with the content of "recognition failure", step S504 can consider the previously executed identity recognition results of the higher processing level, and judge by obtaining the first summed result thereof. The first summed result satisfying the threshold condition indicates that the previously executed identity recognition results of the higher processing level have good performance and thus have high credibility, so the current processing level, i.e., the unlocking item of the processing level corresponding to the identity recognition result itself with the content of "recognition failure", can be continued to be trusted (for example,Figure 5 If the unlocking item 3) is configured as "activated", then it will not be trusted and, based on the identity recognition result of "identity recognition failure", the unlocking item of the current processing level will be configured as "inactive". Therefore, by executing step S504, in the event that the identity recognition module 3 (seat pressure sensor) fails to recognize due to damage or other accidental factors, the recognition result of the previously executed higher-level processing level can be invoked to assist in unlocking the unlocking item of this processing level, thereby improving the unlocking success rate of legitimate users and ensuring the overall availability of the multi-level identity authentication system.

[0047] In this embodiment, refer to Figure 5 In step S504, for the marked unlocking items, i.e., unlocking item 3 that is configured as "activated" based on the threshold condition met by the first summation result, a limitation on the activation validity period is configured. The activation validity period can specifically be 1 minute, etc. After configuring the activation validity period, the control module can start a countdown. When the countdown ends, unlocking item 3 is reconfigured as "inactive". The control module can generate a prompt message, which can be "Unlocking item 3 has been temporarily activated. Please use the identity recognition module 4 (in-vehicle DMS camera) for identity authentication as soon as possible within the activation validity period." The control module calls the human-machine interaction module to display the prompt message, thereby alerting the user.

[0048] In this embodiment, refer to Figure 6 During step S504, if the user is in the lowest level of the identity verification module [ Figure 6 If the identity recognition module 4 (in-vehicle DMS camera) in the system fails to recognize the identity, the unlocking item (unlocking item 4) at the lowest processing level will be "inactive". Therefore, the control module will then process the identity recognition module at the highest processing level. Figure 6 The detection range of the identity recognition module 1 (digital key module) in the system can be limited. For example, the effective detection radius of the identity recognition module 1 (digital key module) can be reduced, or the identity recognition module 1 (digital key module) can be functionally locked (equivalent to limiting its detection range to 0). This would require the user to get closer to the car to enter the detection range of the identity recognition module 1 (digital key module) or to manually open the door to authenticate their identity. Once the authentication is successful by manually opening the door, the detection range limitation of the highest-level processing identity recognition module can be lifted.

[0049] pass Figure 6The processing in the embodiment can establish feedback from the lowest level processing hierarchy to the highest level processing hierarchy in multiple processing hierarchies, thereby obtaining a downward cross-level configuration mode of closed-loop control, and improving the safety of the vehicle.

[0050] In the embodiment, if the situation shown in FIG. 5B occurs, that is, when the peer configuration mode is executed, an identity recognition result with the content of “recognition failure” occurs, so that the unlocking item corresponding to the same processing hierarchy of the identity recognition result should be configured as “inactive” originally, but is configured as “active” according to the first total result, the control module determines that the second trigger condition is met, and then step S505-S506 is executed. Figure 5

[0051] In the embodiment, when the control module executes step S5, that is, when the active state of each unlocking item is configured according to each identity recognition result, the following steps can be executed: S505. When the second trigger condition is met, determine to execute the upward cross-level configuration mode; S506. In the upward cross-level configuration mode, for the unlocking item configured with the active validity period, the identity recognition result of at least one lower level processing hierarchy corresponding to the unlocking item is obtained, and a second total result is obtained by totalizing the identity recognition result. When the second total result meets the threshold condition, the restriction of the active validity period of the unlocking item is cancelled, and when the second total result does not meet the threshold condition, the restriction of the active validity period of the unlocking item is maintained.

[0052] In the embodiment, the principle of steps S505-S506 is as shown in FIG. 5C. Figure 7

[0053] In step S506, for the identity recognition result with the content of “recognition success”, for example Figure 7 The identity recognition result detected by the identity recognition module 1 (digital key module) and the identity recognition module 2 (out-of-vehicle surround view camera) in FIG. 4B is configured as “active” as the unlocking item corresponding to the same processing hierarchy as the peer configuration mode.

[0054] In step S506, for the identity recognition result with the content of “recognition failure” itself, for example Figure 7 The unlocking item 3 corresponding to the identity recognition result detected by the identity recognition module 3 (seat pressure sensor) in FIG. 4B is configured with an active validity period, so that the user can be identified by the identity recognition module 4 (in-vehicle DMS camera) in the lower level processing hierarchy, that is, the processing hierarchy 4, to obtain an identity recognition result. In the embodiment, similar to the calculation of the first total result, since Figure 7 ​​If there is only one lower-level identification result, namely the identification result of identification module 4 (in-vehicle DMS camera), then this identification result itself is used as the second summation result. If the second summation result meets the threshold condition (e.g., less than the threshold), then the restriction on the activation validity period of unlocking item 3 is lifted, so that unlocking item 3 is continuously activated. Conversely, if the second summation result does not meet the threshold condition (e.g., greater than the threshold), then the restriction on the activation validity period of unlocking item is maintained, so that after the activation validity period expires, unlocking item 4 is converted to "inactive".

[0055] In this embodiment, the principle of executing steps S505-S506 is as follows: (Referring to...) Figure 7 For an identity recognition result whose content is "recognition failed", executing step S506 is equivalent to unlocking items at the same processing level (e.g., Figure 7 The unlocking item 3) in the system is temporarily activated. If the identity recognition result of a lower-level processing layer subsequently meets the threshold condition, the system compensates for the "recognition failed" identity recognition result based on trust in the lower-level processing layer's recognition result, thus configuring the unlocking item at the processing layer corresponding to the "recognition failed" identity recognition result as "activated". Therefore, by executing step S506, even if the identity recognition module 3 (seat pressure sensor) fails to recognize due to damage or other accidental factors, the system can simultaneously call the recognition results of the previously executed higher-level processing layer and the recognition results of the subsequently executed lower-level processing layer to assist in unlocking the unlocking item at this processing layer, thereby improving the unlocking success rate of legitimate users and ensuring the overall availability of the multi-level identity authentication system.

[0056] In summary, the multi-level identity authentication system for vehicles in this embodiment has the following advantages: Significant cost advantages: Reusing the vehicle's existing surround-view visible light camera and DMS near-infrared camera eliminates the need for additional external near-infrared hardware, greatly reducing the vehicle's hardware and integration costs, while also reducing the complexity of hardware procurement and supply chain management. Safety performance meets standards: The vehicle adopts a phased strategy of "preliminary external authentication + high-precision internal authentication". Externally, a visible light camera is used to complete face detection and coarse liveness assessment, enabling quick door unlocking. Internally, a 3D near-infrared camera from DMS is used to complete high-precision liveness detection and feature comparison, effectively resisting various spoofing attacks and meeting automotive-grade safety and privacy requirements. Shorter deployment cycle: Developed based on the vehicle's existing hardware system, there is no need to design, debug, and adapt new hardware, which simplifies the technology development process, significantly shortens the product development and deployment cycle, and facilitates rapid large-scale application. The user experience is excellent: the entire authentication process does not require user active operation, and the whole process authentication can be triggered by the digital key close to the natural boarding action, which balances convenience and security and improves the user experience.

[0057] In the embodiment, the multi-level identity authentication system applied to the vehicle can be installed on the automobile, so that the multi-level identity authentication system and other components of the automobile form a whole. The automobile installed with the multi-level identity authentication system applied to the vehicle has all the technical effects of the multi-level identity authentication system applied to the vehicle.
