[0039] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] Embodiment 1

[0042] Figure 1A A flowchart of a vehicle starting method based on near field communication is provided in Embodiment 1 of the present invention. This embodiment is applicable to the case where a vehicle is started based on the near field communication NFC function of the vehicle. The method can be executed by a vehicle starting device based on near field communication. The vehicle starting device based on near field communication can be implemented in the form of hardware and / or software. The vehicle starting device based on near field communication can be configured in an electronic device, for example, can be configured in a vehicle controller in a vehicle control system.

[0043] Figure 1B This is a schematic diagram of the structure of a vehicle control system provided in the first embodiment of the present invention. The vehicle control system 10 includes a vehicle controller 11, a digital key control module 12 and a near field communication NFC module 13. The digital key control module 12 is respectively connected to the vehicle controller 11 and the NFC module 13 for communication.

[0044] It should be noted that in order to reduce costs, reduce the number of chips, and improve the flexibility of vehicle layout, the NFC module can be configured in the wireless charging module in the vehicle, and the independent NFC function and wireless charging function can be merged to support two functional scenarios on the same chip. The chip of the NFC module is integrated on the wireless charging PCB (Printed Circuit Board), and the NFC antenna coil and the circuit for wireless charging temperature collection are integrated on the same filter board PCB. This architectural design reduces the number of chips in the controller, reduces costs, and reduces the layout of the entire vehicle. In terms of functional implementation, a security chip is reused with the existing digital key control module on the vehicle for security authentication of the vehicle and mobile phone ends. The digital key control module rather than wireless charging provides the authentication result. The wireless charging controller and NFC module only transparently transmit the data exchange between the two ends and do not participate in the calculation. This implementation logic can adapt to and be compatible with multiple security protocols of digital keys, which to a certain extent reduces the workload of adaptation and development with mobile phone manufacturers.

[0045] like Figure 1A As shown, the method is executed by a vehicle controller in a vehicle control system, and includes:

[0046] S110. When a vehicle startup request initiated by a user terminal based on the NFC function is monitored, a secure random number is generated, and the secure random number is sent to a digital key control module, so that the digital key control module generates and feeds back a first response value based on the secure random number.

[0047] The user can initiate a vehicle start request through the NFC function provided in the user terminal. The user terminal can be a mobile phone or a tablet. When the vehicle controller monitors the vehicle start request, it performs security verification on the vehicle start request. The security verification can include anti-theft security verification and authority security verification.

[0048] The vehicle-side controller randomly generates a secure random number and sends the secure random number to the digital key control module. The digital key control module calculates the secure random number based on a preset encryption algorithm or key, such as a hash algorithm, to obtain a first response value, and feeds the first response value back to the vehicle-side controller. The encryption algorithm or key in the digital key control module can be pre-configured by relevant technical personnel, and can be the same as the encryption algorithm key in the vehicle-side controller, or can be a symmetric encryption algorithm or key, which is not limited in this embodiment.

[0049] S120: Perform a security check on the vehicle startup request according to the security random number and the first response value.

[0050] The vehicle-side controller can compare the response value generated based on the secure random number with the response value fed back by the digital key control module, and thus perform security verification on the vehicle startup request based on the comparison result.

[0051] In an optional embodiment, a security check is performed on a vehicle startup request based on a security random number and a first response value, including: generating a second response value based on the security random number; performing an authority security check on the vehicle startup request based on the first response value and the second response value to obtain an authority security check result; obtaining user location information of the user terminal and obtaining vehicle location information of the vehicle itself; performing an anti-theft security check on the vehicle startup request based on the user location information and the vehicle location information to obtain an anti-theft security check result; performing a security check on the vehicle startup request based on the authority security check result and the anti-theft security check result.

[0052] The vehicle-side controller encrypts and calculates the secure random number based on the same or corresponding encryption algorithm or key deployed by the digital key control module to obtain a second response value. The first response value and the second response value are compared for consistency. If they are consistent, the authority security verification of the vehicle startup request has passed; if they are inconsistent, the authority security verification of the vehicle startup request has failed.

[0053] The user location information of the user terminal is obtained, and the vehicle location information of the vehicle itself is obtained; if the distance between the user location and the vehicle location is less than a preset distance threshold, the anti-theft safety detection of the vehicle start request is passed; if the distance between the user location and the vehicle location is not less than the preset distance threshold, the anti-theft safety detection of the vehicle start request is not passed. The distance threshold can be preset by relevant technical personnel, for example, the distance threshold can be set to 2m.

[0054] If the authority security test result passes and the anti-theft security test result passes, the security test for the vehicle startup request passes; if the authority security test result fails or the anti-theft security test result fails, the security test for the vehicle startup request fails.

[0055] In order to further ensure that the results of the authority security detection have a certain degree of fault tolerance, thereby improving the accuracy of the authority security detection results and avoiding sudden anomalies in the vehicle controller and the digital key control module in a certain calculation cycle that may cause deviations in the calculation results in the calculation cycle, this embodiment also provides a method for accurately determining the results of the authority security detection.

[0056] In an optional embodiment, a permission security check is performed on a vehicle startup request based on a first response value and a second response value to obtain a permission security check result, including: numerically comparing the first response value and the second response value, and if the comparison results are inconsistent, generating at least two reference random numbers in a current iteration cycle, and sending each reference random number to a digital key control module, so that the digital key control module generates a first reference response value corresponding to each reference random number; generating a second reference response value for each reference random number based on each reference random number; comparing each first reference response value with the corresponding second reference response value to obtain a comparison result of each reference random number in the current iteration cycle; performing a permission security check on the vehicle startup request based on the comparison result of each reference random number in each iteration cycle to obtain a permission security check result.

[0057] If the comparison results of the first response value and the second response value are inconsistent, a preset iteration cycle may be pre-set, for example, the preset iteration cycle may be 5 cycles.

[0058] For any preset iteration cycle, in the current iteration cycle, the vehicle controller generates at least two reference random numbers and sends each reference random number to the digital key control module. The digital key control module calculates each reference random number based on a pre-configured encryption algorithm or key to obtain a first reference response value corresponding to each reference random number. At the same time, the vehicle controller calculates each reference random number based on the same or corresponding encryption algorithm or key as the digital key control module to obtain a second reference response value corresponding to each reference random number.

[0059] The vehicle controller compares each first reference response value with the corresponding second reference response value for consistency, and obtains the comparison results of each reference random number. If a preset number of comparison results are consistent among the comparison results, it is determined that the permission security detection result in the current iteration cycle has passed. Based on the permission security detection results in each iteration cycle, the permission security detection result of the vehicle startup request is determined. Specifically, if the permission security detection results of more than 90% of the iteration cycles pass, it can be considered that the permission security detection result of the vehicle startup request has passed.

[0060] S130. If the security test result passes, a digital key search request is generated, and the digital key search request is sent to the NFC module through the digital key control module, so that the NFC module can interact with the user terminal based on the digital key search request, and after finding the digital key, a status check request is generated and sent to the digital key control module. The digital key control module performs a status check on the digital key based on the status check request, obtains a status check result, and sends the status check result to the vehicle controller.

[0061] If the security result of the vehicle startup request is passed, the vehicle controller generates a digital key search request; if the security result of the vehicle startup request is not passed, a failure prompt message is generated and fed back to the user terminal.

[0062] The vehicle controller sends the digital key search request to the NFC module through the digital key control module; after receiving the digital key search request, the NFC module parses the digital key search request, determines the user terminal, and interacts with the user terminal to find whether the digital key exists. After being able to query the corresponding digital key, it generates a status check request and sends the status check request to the digital key control module. Based on the status check request, the digital key control module performs a status check on the digital key, obtains the status check result, and sends the status check result to the vehicle controller.

[0063] In an optional embodiment, the digital key control module performs a status check on the digital key based on a status check request to obtain a status check result, including: according to the status check request, based on a preset shared key, performing a signature verification on the digital signature of the digital key to obtain a legitimacy verification result; if the legitimacy verification result passes, performing a permission verification on the access rights of the digital key to obtain a permission verification result; if the permission verification result passes, performing a status verification on the current status of the vehicle to obtain a status check result.

[0064] After receiving the status check request, the digital key control module can parse the status check request, obtain the digital key, and verify the validity of the digital key. Specifically, it can perform signature verification on the digital signature of the parsed digital key to verify whether the signature is legal and obtain the legality verification result. If the legality verification passes, the access rights of the digital key are verified; if the legality verification fails, a failure prompt message is generated and sent to the user terminal.

[0065] The access rights verification of the digital key may specifically include checking the expiration time of the digital key, verifying the identity of the user to which the digital key belongs, etc. If the access rights verification of the digital key passes, the status check result is check passed; if the access rights verification of the digital key fails, the status check result is check failed.

[0066] S140: Control the vehicle to start according to the status check result.

[0067] When the vehicle controller determines that the status check result is passed, it controls the vehicle to start.

[0068] In an optional embodiment, after the digital key search request is sent to the NFC module through the digital key control module, it also includes: if the status check result sent by the digital key control module is not received within a preset time period, the digital key search request is sent to the NFC module again through the digital key control module; if the number of times the digital key search request is sent to the NFC module reaches a preset sending threshold, a preset prompt message is generated and the prompt message is sent to the instrument display.

[0069] The preset time period and the threshold of the number of transmissions can be preset by relevant technical personnel. For example, the threshold of the number of transmissions can be 3 times.

[0070] If the status check result sent by the digital key control module is not received within the preset sending number threshold, a preset prompt message is generated and sent to the instrument display. The prompt message may be, for example, "There is no valid key in the car, please restart in the NFC start area."

[0071] The technical solution of the embodiment of the present invention generates a secure random number when monitoring the vehicle start request initiated by the user terminal based on the NFC function, and sends the secure random number to the digital key control module, so that the digital key control module generates and feeds back a first response value based on the secure random number; performs a security check on the vehicle start request according to the secure random number and the first response value; if the security check result passes, a digital key search request is generated, and the digital key search request is sent to the NFC module, so that after the NFC module finds the digital key, it generates and sends a status check request to the digital key control module, and the digital key control module performs a status check on the digital key based on the status check request, obtains a status check result, and sends the status check result to the vehicle controller; according to the status check result, the vehicle is controlled to start. The above technical solution introduces a security detection method to perform a request detection on the vehicle start request initiated based on the NFC function, thereby improving the detection security of the NFC key and improving the security of starting the vehicle based on the NFC function. The NFC module only participates in data exchange, and the digital key control module performs data authentication such as status check, so as to achieve logical adaptation and compatibility with multiple security protocols of the digital key, and reduce the workload of mobile phone adaptation development.

[0072] Embodiment 2

[0073] Figure 2 A flowchart of a vehicle starting method based on near field communication is provided for embodiment 2 of the present invention. This embodiment is applicable to the situation where a vehicle is started based on the near field communication NFC function of the vehicle. The method can be executed by a vehicle starting device based on near field communication. The vehicle starting device based on near field communication can be implemented in the form of hardware and / or software. The vehicle starting device based on near field communication can be configured in an electronic device, for example, a digital key control module in a vehicle control system.

[0074] like Figure 2 As shown, the method is executed by a digital key control module in a vehicle control system, and includes:

[0075] S210: Obtain a secure random number generated by the vehicle controller when monitoring a vehicle start request initiated by a user terminal based on an NFC function.

[0076] The user can initiate a vehicle start request through the NFC function provided in the user terminal. The user terminal can be a mobile phone or a tablet. When the vehicle controller monitors the vehicle start request, it performs security verification on the vehicle start request. The security verification can include anti-theft security verification and authority security verification.

[0077] The vehicle-side controller randomly generates a secure random number and sends the secure random number to the digital key control module. The digital key control module calculates the secure random number based on a preset encryption algorithm or key, such as a hash algorithm, to obtain a first response value, and feeds the first response value back to the vehicle-side controller. The encryption algorithm or key in the digital key control module can be pre-configured by relevant technical personnel, and can be the same as the encryption algorithm key in the vehicle-side controller, or can be a symmetric encryption algorithm or key, which is not limited in this embodiment.

[0078] S220. Based on the security random number, generate and feed back a first response value to the vehicle controller, so that the vehicle controller can perform a security check on the vehicle startup request according to the security random number and the first response value, and generate and feed back a digital key search request when the security check result passes.

[0079] The vehicle-side controller can compare the response value generated based on the secure random number with the response value fed back by the digital key control module, and thus perform security verification on the vehicle startup request based on the comparison result.

[0080] In an optional embodiment, a security check is performed on a vehicle startup request based on a security random number and a first response value, including: generating a second response value based on the security random number; performing an authority security check on the vehicle startup request based on the first response value and the second response value to obtain an authority security check result; obtaining user location information of the user terminal and obtaining vehicle location information of the vehicle itself; performing an anti-theft security check on the vehicle startup request based on the user location information and the vehicle location information to obtain an anti-theft security check result; performing a security check on the vehicle startup request based on the authority security check result and the anti-theft security check result.

[0081] The vehicle-side controller encrypts and calculates the secure random number based on the same or corresponding encryption algorithm or key deployed by the digital key control module to obtain a second response value. The first response value and the second response value are compared for consistency. If they are consistent, the authority security verification of the vehicle startup request has passed; if they are inconsistent, the authority security verification of the vehicle startup request has failed.

[0082] The user location information of the user terminal is obtained, and the vehicle location information of the vehicle itself is obtained; if the distance between the user location and the vehicle location is less than a preset distance threshold, the anti-theft safety detection of the vehicle start request is passed; if the distance between the user location and the vehicle location is not less than the preset distance threshold, the anti-theft safety detection of the vehicle start request is not passed. The distance threshold can be preset by relevant technical personnel, for example, the distance threshold can be set to 2m.

[0083] If the authority security test result passes and the anti-theft security test result passes, the security test for the vehicle startup request passes; if the authority security test result fails or the anti-theft security test result fails, the security test for the vehicle startup request fails.

[0084] S230: Send a digital key search request to the NFC module, so that the NFC module interacts with the user terminal based on the digital key search request, and generates and feeds back a status check request after finding the digital key.

[0085] If the security result of the vehicle startup request is passed, the vehicle controller generates a digital key search request; if the security result of the vehicle startup request is not passed, a failure prompt message is generated and fed back to the user terminal.

[0086] The vehicle controller sends the digital key search request to the NFC module through the digital key control module; after receiving the digital key search request, the NFC module parses the digital key search request, determines the user terminal, and interacts with the user terminal to find out whether the digital key exists. After the corresponding digital key can be queried, a status check request is generated and sent to the digital key control module.

[0087] S240: Based on the status check request, perform a status check on the digital key, obtain a status check result, and send the status check result to the vehicle controller so that the vehicle controller can control the vehicle to start according to the status check result.

[0088] If the digital key control module determines that the status check result is that the status monitoring is passed, the vehicle controller controls the vehicle to start.

[0089] In an optional embodiment, based on a status check request, a status check is performed on the digital key to obtain a status check result, including: according to the status check request, based on a preset shared key, a signature verification is performed on the digital signature of the digital key to obtain a legitimacy verification result; if the legitimacy verification result passes, a permission verification is performed on the access rights of the digital key to obtain a permission verification result; if the permission verification result passes, a status verification is performed on the current status of the vehicle to obtain a status check result.

[0090] After receiving the status check request, the digital key control module can parse the status check request, obtain the digital key, and verify the validity of the digital key. Specifically, it can perform signature verification on the digital signature of the parsed digital key to verify whether the signature is legal and obtain the legality verification result. If the legality verification passes, the access rights of the digital key are verified; if the legality verification fails, a failure prompt message is generated and sent to the user terminal.

[0091] The access rights verification of the digital key may specifically include checking the expiration time of the digital key, verifying the identity of the user to which the digital key belongs, etc. If the access rights verification of the digital key passes, the status check result is check passed; if the access rights verification of the digital key fails, the status check result is check failed.

[0092] In another vehicle startup scenario, the user touches the NFC startup area with the terminal device. When NFC receives the request signal from the user terminal, it generates a standard authentication request and sends the standard authentication request to the digital key control module to execute the authentication process.
