Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a vehicle control method, device, and equipment based on remote control keys and digital keys. Background Technology

[0002] Currently, when vehicles are equipped with both physical remote keys and digital keys (mobile phones / wearable devices), there are significant potential conflicts and theft vulnerabilities: 1) Frequent functional conflicts: The remote key and digital key are relatively independent control systems, which are prone to signal interference or command conflicts. For example, after the digital key locks the car, the remote key will trigger automatic locking when it unlocks; after the vehicle is started remotely, the remote key will completely malfunction, which seriously affects the user experience.

[0003] 2) Lack of conflict detection: Existing technologies lack a precise conflict identification mechanism and rely solely on manual switching by the user (such as using a remote key to unlock and restore the physical key mode), which is slow to respond and cumbersome to operate, and cannot achieve seamless collaboration.

[0004] 3) Increased risk of theft: Unauthorized personnel can exploit the dual-key signal conflict vulnerability to steal cars, such as by interfering with the digital key signal to force the system to switch to remote key mode and then cracking the remote control signal; or by taking advantage of the unlocking abnormality caused by the conflict to sneak into the vehicle.

[0005] 4) Poor adaptability: Existing anti-collision solutions are mostly designed for the same type of key (such as multiple remote keys), and adopt hardware improvement methods such as frequency hopping. These methods are costly and cannot adapt to the cross-protocol differences between remote keys and digital keys, resulting in insufficient universality.

[0006] The above problems urgently need to be addressed. Summary of the Invention

[0007] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.

[0008] Therefore, one objective of this invention is to provide a vehicle control method based on a remote key and a digital key. When the vehicle receives both a remote key signal and a digital key signal and there is a conflict between them, the method performs a security risk assessment to obtain a security risk value for the remote key and a security risk value for the digital key. The method then selects the key signal with the lower security risk value and controls the vehicle. This solves the functional conflict problem when two keys coexist, improves the vehicle's anti-theft security and the user experience, and is applicable to intelligent connected vehicles that are compatible with both traditional remote keys and smart digital keys.

[0009] Another objective of this invention is to provide a vehicle control device based on a remote key and a digital key.

[0010] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of the present invention include: On one hand, embodiments of the present invention provide a vehicle control method based on a remote key and a digital key, comprising the following steps: When the target vehicle receives both the remote key signal and the digital key signal, it is determined whether the remote key signal and the digital key signal conflict. When the remote key signal conflicts with the digital key signal, a security risk assessment is performed on the remote key signal and the digital key signal respectively to obtain the remote key security risk value and the digital key security risk value. The target key signal is selected from the remote key signal and the digital key signal based on the security risk value of the remote key and the security risk value of the digital key, and the target vehicle is controlled based on the target key signal.

[0011] Furthermore, in one embodiment of the present invention, determining whether the remote control key signal conflicts with the digital key signal specifically includes: Determine the operation command type and command transmission timestamp of the remote control key signal and the digital key signal; If the time interval between the timestamps of the instructions sent by the two devices is less than or equal to a preset first threshold, and the types of the operation instructions are different, it is determined that the remote control key signal and the digital key signal conflict.

[0012] Furthermore, in one embodiment of the present invention, a security risk assessment of the remote key signal is performed through the following steps: The first signal strength, first frequency fluctuation, first signal transmission position, and first user operation behavior corresponding to the remote key signal are determined, and the current vehicle position and owner operation habits of the target vehicle are determined. The first signal anomaly risk value is determined based on the first signal strength and the first frequency fluctuation. The first position matching risk value is determined based on the matching degree between the first signal transmission position and the current vehicle position; The risk value of the first behavior pattern is determined based on the consistency between the first user's operation behavior and the car owner's operation habits; The first signal anomaly risk value, the first location matching risk value, and the first behavior pattern risk value are weighted and summed according to a preset first weight parameter to obtain the remote key security risk value.

[0013] Furthermore, in one embodiment of the present invention, a security risk assessment of the digital key signal is performed through the following steps: The first communication protocol, signal integrity, ultra-wideband positioning information, and first user biometrics corresponding to the digital key signal are determined, and the location of the digital key terminal and the biometrics of the vehicle owner of the target vehicle are determined. A second signal anomaly risk value is determined based on the first communication protocol and the signal integrity. The second location matching risk value is determined based on the matching degree between the ultra-wideband positioning information and the location of the digital key terminal; The risk value of the second behavioral pattern is determined based on the consistency between the first user's biometrics and the vehicle owner's biometrics; The digital key security risk value is obtained by weighting and summing the second signal anomaly risk value, the second location matching risk value, and the second behavior pattern risk value according to the preset second weighting parameter.

[0014] Furthermore, in one embodiment of the present invention, the step of filtering a target key signal from the remote key signal and the digital key signal based on the remote key security risk value and the digital key security risk value, and controlling the target vehicle based on the target key signal, specifically includes: The target key signal is the key signal corresponding to the smaller value between the security risk value of the remote key and the security risk value of the digital key. The target vehicle is controlled according to the operation instructions of the target key signal.

[0015] Furthermore, in one embodiment of the present invention, the vehicle control method further includes the following steps: When the security risk value of the remote key or the security risk value of the digital key is greater than or equal to a preset second threshold, the signal transmitter corresponding to the remote key signal or the digital key signal is added to the blacklist and an early warning is triggered.

[0016] Furthermore, in one embodiment of the present invention, the vehicle control method further includes the following steps: When the security risk value corresponding to the target key signal is greater than or equal to a preset second threshold, the target key signal is then subjected to secondary authorization verification, and the target vehicle is controlled according to the target key signal after the verification is successful.

[0017] On the other hand, embodiments of the present invention provide a vehicle control device based on a remote key and a digital key, comprising: The signal conflict determination module is used to determine whether the remote key signal and the digital key signal conflict when the target vehicle receives the remote key signal and the digital key signal. The security risk assessment module is used to perform security risk assessments on the remote key signal and the digital key signal respectively when the remote key signal conflicts with the digital key signal, and obtain the security risk value of the remote key and the security risk value of the digital key. The key signal filtering module is used to filter out target key signals from the remote key signals and digital key signals based on the security risk value of the remote key and the security risk value of the digital key, and to control the target vehicle based on the target key signals.

[0020] On the other hand, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the above-described vehicle control method based on a remote key and a digital key.

[0021] The advantages and beneficial effects of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention: In this embodiment of the invention, when a target vehicle receives both a remote key signal and a digital key signal, it determines whether the remote key signal and the digital key signal conflict. If they conflict, a security risk assessment is performed on both signals to obtain a remote key security risk value and a digital key security risk value. Based on these values, a target key signal is selected from the remote key signal and the digital key signal, and the target vehicle is controlled according to this target key signal.

The terminology used herein is for the purpose of describing embodiments of the invention only and is not intended to limit the invention.

[0026] The vehicle control method based on remote key and digital key provided in this invention can be applied to a terminal, a server, or software running on a terminal or server. In some embodiments, the terminal can be a smartphone, tablet, laptop, desktop computer, smart speaker, smartwatch, or in-vehicle terminal, but is not limited to these. The server can be configured as an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The server can also be a node server in a blockchain network. The software can be an application that implements the vehicle control method based on remote key and digital key, but is not limited to the above forms.

[0027] This invention can be used in a wide variety of general-purpose or special-purpose computer system environments or configurations. Examples include: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, and distributed computing environments including any of the above systems or devices. This invention can be described in the general context of computer-executable instructions, such as program modules, that are executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc., that perform specific tasks or implement specific abstract data types. This invention can also be practiced in distributed computing environments where tasks are performed by remote processing devices connected via a communication network. In distributed computing environments, program modules can reside in local and remote computer storage media, including storage devices.

[0028] It should be noted that in various specific embodiments of the present invention, when processing data related to user identity or characteristics, such as user information, user behavior data, user historical data, and user parking space location information, user permission or consent is obtained first. Furthermore, the collection, use, and processing of this data comply with relevant laws, regulations, and standards. In addition, when embodiments of the present invention require access to sensitive personal information of users, separate permission or consent from the user is obtained through pop-ups or redirection to a confirmation page. Only after obtaining the user's separate permission or consent is the necessary user-related data for the normal operation of the embodiments of the present invention acquired.

[0029] Reference Figure 1 This invention provides a vehicle control method based on a remote key and a digital key, specifically including the following steps: S101. When the target vehicle receives both the remote key signal and the digital key signal, determine whether the remote key signal and the digital key signal conflict. S102. When the remote key signal conflicts with the digital key signal, perform a security risk assessment on the remote key signal and the digital key signal respectively to obtain the security risk value of the remote key and the security risk value of the digital key. S103. Select the target key signal from the remote key signal and the digital key signal based on the remote key security risk value and the digital key security risk value, and control the target vehicle based on the target key signal.

[0030] In this embodiment of the invention, when a vehicle receives both a remote key signal and a digital key signal and there is a conflict between the two, a security risk assessment is performed to obtain the security risk values ​​of the remote key and the digital key. The key signal with the lower security risk value is selected and the vehicle is controlled. This solves the functional conflict problem when two keys coexist, improves the anti-theft security of the vehicle and the user experience, and is applicable to intelligent connected vehicles that are compatible with both traditional remote keys and smart digital keys.

[0031] The vehicle-mounted dual-protocol authentication module of this invention is adapted to the radio frequency (RF) signal authentication of the remote key and the Bluetooth / UWB protocol authentication of the digital key, respectively. It supports accurate identification of key identity (unique ID) and authorization permissions (unlocking / starting / tailgate control, etc.). The authentication data is encrypted and transmitted using the national cryptographic SM4 encryption algorithm to prevent identity information from being cracked or forged. At the same time, it stores the identity information of the bound remote key and digital key to form a "whitelist" database.

[0032] As a further optional implementation, determining whether the remote key signal and the digital key signal conflict specifically includes: S1011. Determine the operation command type and command transmission timestamp of the remote control key signal and digital key signal; S1012. When the time interval between the timestamps of the two instruction transmissions is less than or equal to a preset first threshold, and the two operation instruction types are different, it is determined that the remote control key signal and the digital key signal conflict.

[0033] Specifically, the remote key signal and digital key signal are collected in real time, along with the timestamps of the command transmission and the type of operation command (unlock / lock / start). When different operation commands from the remote key and digital key are received within the same time period (e.g., 1 second), it is determined that the remote key signal and the digital key signal are in conflict.

[0034] As an optional further implementation, a security risk assessment of the remote key signal is conducted through the following steps: S201. Determine the first signal strength, first frequency fluctuation, first signal transmission position, and first user operation behavior corresponding to the remote key signal, and determine the current vehicle position and owner's operation habits of the target vehicle. S202. Determine the abnormal risk value of the first signal based on the first signal strength and the first frequency fluctuation; S203. Determine the first position matching risk value based on the matching degree between the first signal transmission position and the current vehicle position; S204. Determine the risk value of the first behavior pattern based on the consistency between the first user's operation behavior and the vehicle owner's operation habits; S205. The first signal abnormality risk value, the first position matching risk value, and the first behavior pattern risk value are weighted and summed according to the preset first weight parameter to obtain the remote key security risk value.

[0035] Specifically, the system monitors the first signal strength and first frequency fluctuations corresponding to the remote key signal in real time. Based on these fluctuations, it determines the first signal anomaly risk value. For example, if the signal strength is abnormally strong (possibly amplified by a relay) or the frequency fluctuations exceed the normal range, the corresponding first signal anomaly risk value is high. It also determines the first location matching risk value based on the matching degree between the first signal transmission location of the remote key signal and the vehicle's location. For example, if the distance between the key location and the vehicle exceeds 100 meters, but the vehicle can still receive a clear signal (a relay attack characteristic), the corresponding first location matching risk value is high. Finally, it determines the first behavior pattern risk value based on the consistency between the first user's operating behavior and the vehicle owner's operating habits. For example, if there are instances of operating at uncommon times, multiple consecutive unlocking failures, or operating locations that do not match the usual routes, the corresponding first behavior pattern risk value is high. Finally, it weights and sums the first signal anomaly risk value, the first location matching risk value, and the first behavior pattern risk value according to preset first weight parameters to obtain the remote key security risk value.

[0036] As an optional further implementation, a security risk assessment of the digital key signal is conducted through the following steps: S301. Determine the first communication protocol, signal integrity, ultra-wideband positioning information and first user biometrics corresponding to the digital key signal, and determine the location of the digital key terminal and the biometrics of the vehicle owner of the target vehicle. S302. Determine the second signal anomaly risk value based on the first communication protocol and signal integrity. S303. Determine the second location matching risk value based on the matching degree between the ultra-wideband positioning information and the location of the digital key terminal; S304. Determine the risk value of the second behavioral pattern based on the consistency between the first user's biometric characteristics and the vehicle owner's biometric characteristics; S305. The second signal anomaly risk value, the second position matching risk value, and the second behavior pattern risk value are weighted and summed according to the preset second weighting parameter to obtain the digital key security risk value.

[0037] Specifically, the system monitors the first communication protocol and signal integrity of the digital key signal in real time. Based on the first communication protocol and signal integrity, a second signal anomaly risk value is determined. For example, the second signal anomaly risk value is higher when using unencrypted Bluetooth connection, not employing end-to-end encryption, or when the signal is tampered with or forged. A second location matching risk value is determined based on the matching degree between the ultra-wideband positioning information of the digital key signal and the location of the digital key terminal. For example, the second location matching risk value is higher when the digital key terminal is around the vehicle but the ultra-wideband positioning information is more than a safety threshold away from the vehicle. A second behavioral pattern risk value is determined based on the consistency between the first user's biometric features and the vehicle owner's biometric features. For example, the second behavioral pattern risk value is higher when biometric verification is not performed or when biometric features do not match. The second signal anomaly risk value, the second location matching risk value, and the second behavioral pattern risk value are weighted and summed according to a preset second weight parameter to obtain the digital key security risk value.

[0038] As a further optional implementation, a target key signal is selected from the remote key signal and the digital key signal based on the security risk value of the remote key and the security risk value of the digital key, and the target vehicle is controlled based on the target key signal, specifically including: S1031. The target key signal is the key signal corresponding to the smaller value between the security risk value of the remote key and the security risk value of the digital key. S1032. Control the target vehicle according to the operation instructions of the target key signal.

[0039] Specifically, the key signal corresponding to the smaller value between the remote key security risk value and the digital key security risk value is selected as the target key signal, and the vehicle is controlled to perform operations such as unlocking, locking, and starting according to its corresponding operation instructions.

[0040] As an optional implementation, the vehicle control method further includes the following steps: S104. When the security risk value of the remote key or the security risk value of the digital key is greater than or equal to the preset second threshold, the signal transmitter corresponding to the remote key signal or the digital key signal is added to the blacklist and an early warning is triggered.

[0041] Specifically, when the security risk values ​​of the remote key and the digital key both exceed a preset second threshold, the transmitter model corresponding to that key signal is added to the blacklist. An immediate warning is sent via the vehicle's infotainment system and the user's mobile app, simultaneously recording conflict and warning logs. All conflict and abnormal operation logs are uploaded to the cloud platform in real time for users and regulatory agencies to access, facilitating the determination and tracing of responsibility for car theft incidents.

[0042] As an optional implementation, the vehicle control method further includes the following steps: S105. When the security risk value corresponding to the target key signal is greater than or equal to the preset second threshold, the target key signal is then subjected to secondary authorization verification, and the target vehicle is controlled according to the target key signal after the verification is passed.

[0043] Specifically, when the security risk value corresponding to the target key signal is greater than or equal to the preset second threshold, the system locks the operation of the currently authorized key and requires secondary verification (such as facial recognition for digital keys and input of a preset password for remote keys). After the verification is successful, the system controls the target vehicle according to the target key signal.

[0044] In some optional embodiments, the present invention supports users to view key permission status, customize key priority, and query conflict logs through the vehicle system or mobile APP. It also provides an emergency unlocking interface. When all keys fail due to a conflict, users can unlock the car by scanning a code through the APP or by remote authentication (biometric identification + password) to restore single-key control.

[0045] The method steps of the embodiments of the present invention have been described above. It can be understood that, in the embodiments of the present invention, when the vehicle receives both a remote key signal and a digital key signal and there is a conflict between the two, a security risk assessment is performed to obtain the security risk value of the remote key and the security risk value of the digital key, and the key signal with the lower security risk value is selected to control the vehicle. This solves the functional conflict problem when two keys coexist, improves the anti-theft security of the vehicle and the user experience, and is applicable to intelligent connected vehicles compatible with both traditional remote keys and smart digital keys.
