[0032] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0033] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0034] In an exemplary embodiment, Figure 1 This is a schematic diagram of a scenario of a vehicle unlocking method provided by an embodiment of the present application. Figure 1 As shown, the scenario 100 includes a vehicle 110 and a terminal 120. Vehicle 110 is equipped with a Bluetooth module for communicating with terminal 120, a Near Field Communication (NFC) module, a positioning module, a security chip, and the like. Furthermore, vehicle networking services are enabled to support communication with terminal 120 equipped with ultra-wideband (UWB) wireless communication technology.

[0035] Terminal 120 can be an electronic device such as a smartphone, tablet computer, or PDA, supporting ultra-UWB and NFC communication technologies. Terminal 120 can also be installed with multiple applications (APPs), such as a vehicle manufacturer APP 1201 for unlocking the vehicle and a wallet APP 1202. Terminal 120 also includes a Bluetooth module 1203 for communicating with vehicle 110 and a positioning module for obtaining its own location.

[0036] For example, when a user is near a vehicle and wants to unlock the vehicle using the Bluetooth key configured in the terminal 120, the user must remove the terminal 120 from a pocket or backpack, open the vehicle manufacturer's app 1201, and trigger the unlock button to unlock the vehicle. This makes the process of unlocking the vehicle using the Bluetooth key rather cumbersome, and the user cannot use the Bluetooth key to unlock the vehicle if the terminal 120 is powered off.

[0037] Therefore, the present application provides a vehicle unlocking method, which can make the vehicle unlocking process simpler and more intelligent.

[0038] In an exemplary embodiment, Figure 2 This is a schematic flow chart of a vehicle unlocking method provided by an embodiment of the present application. Figure 2 As shown, the method 200 includes the following implementation process:

[0039] In S210 , the vehicle 110 obtains the location of the terminal.

[0040] The terminal and the vehicle establish a communication connection for information transmission, and the terminal's location refers to the location of the terminal at a certain point in time. For example, at 12:00, the terminal's location refers to the location at 12:00.

[0041] For example, vehicle 110 obtains the location of the terminal at 12:00. There are two situations in which vehicle 110 can obtain the location of the terminal, or it can't. If vehicle 110 obtains the location of terminal 120, it can indicate that the user intends to unlock the vehicle at 12:00. If vehicle 110 cannot obtain the location of terminal 120, it can indicate that the user does not intend to unlock the vehicle at 12:00.

[0042] When the vehicle 110 obtains the position of the terminal 120 , S220 is continued to be executed to calculate the distance between the position of the terminal and the position of the vehicle, and to determine whether the distance satisfies a first preset range.

[0043] Among them, the position of the terminal can be obtained by the positioning module set in the terminal 120, the position of the vehicle can be obtained by the positioning module set in the vehicle 110, and the distance between the position of the terminal 120 and the position of the vehicle 110 can change with the position of the terminal 120, and is not fixed.

[0044] Among them, the first preset range can refer to the distance centered on the vehicle 110, which can be 2 meters, 1 meter, or 0.5 meters, and this embodiment of the present application does not limit this.

[0045] In an exemplary embodiment, Figure 3 This is a schematic diagram of the distance between the vehicle and the terminal provided in the embodiment of the present application. Figure 3 As shown, A can represent the position of the terminal 120, B can represent the position of the vehicle 110, that is, the distance between the position of the terminal 120 and the position of the vehicle 110 is AB, which can be set to 5 meters; C can also represent the position of the terminal 120, that is, the distance between the position of the terminal 120 and the position of the vehicle 110 is CB, which can be set to 1 meter; or, D can also represent the position of the terminal 120, that is, the distance between the position of the terminal 120 and the position of the vehicle 110 is DB, which can be set to 0.9 meters.

[0046] refer to Figure 3 The first preset range represents the range covered by a circle with a distance length of CB and a position B of the vehicle 110 as the center, which can be recorded as range b; the first preset range can also represent the range covered by a circle with a distance length of DB and a position B of the vehicle 110 as the center, which can be recorded as range d. This embodiment of the present application does not limit this.

[0047] It should be understood that the location A, location C, or location D of the terminal 120 is a location at different time points.

[0048] Exemplarily, the vehicle 110 calculates the distance between the location of the terminal 120 and its own location, and determines whether the distance satisfies a first preset range. Figure 3 , the first preset range can be set to range b, the vehicle 110 calculates the distance between the position of the terminal 120 and its own position as DB, the distance of DB is 0.9 meters, and determines whether the distance of DB (0.9 meters) meets the range b (1 meter) centered on the vehicle 110.

[0049] When the distance satisfies the first preset range, that is, the DB distance (0.9 meters) between the position of the terminal 120 and the position of the vehicle 110 satisfies the range b (1 meter) centered on the vehicle 110, S240 is executed, and the vehicle 110 receives the digital key sent by the terminal 120 through S230 to unlock the vehicle 110 through the digital key.

[0050] The digital key is generated when the terminal and the vehicle complete data verification, and the digital key refers to an NFC key in the terminal 120 that can be used to unlock the vehicle 110 .

[0051] Among them, S230 can also be executed before S210, or after or at the same time as S210, or S230 can also be executed simultaneously with S220. In other words, S230 can be executed arbitrarily before S240, and the vehicle 110 receives the digital key sent by the terminal 120 when the vehicle 110 calculates that the distance between the position of the terminal 120 and its own position can meet the unlocking condition of 1 meter centered on itself (that is, the first preset condition).

[0052] For example, when the terminal 120 is in a powered-off state, the terminal 120 can use its own NFC module to fit the NFC module provided in the vehicle, thereby establishing a communication connection between the NFC modules so that the digital key can unlock the vehicle.

[0053] exist Figure 2 In the provided technical solution, the vehicle calculates the distance between the acquired terminal position and its own position, and when it determines that the distance meets the set unlocking condition (i.e., the first preset range), it receives the digital key sent by the terminal and uses the digital key to unlock. By calculating the distance between the terminal position and the vehicle position, the method can detect the distance change process in real time, thereby understanding whether the distance between the terminal and the vehicle meets the vehicle unlocking condition. When the distance meets the vehicle unlocking condition, the vehicle automatically unlocks using the digital key received from the terminal, so that the user does not need to activate the smart key for unlocking on the terminal, which can improve the intelligence and simplicity of the vehicle unlocking process; and based on the attribute characteristics of the digital key, when the terminal is in the off state, the NFC module of the terminal can be used to fit the NFC module set in the vehicle, thereby establishing a communication connection between the NFC modules, so that the digital key can unlock the vehicle, ensuring the real-time use of the digital key to unlock the vehicle.

[0054] In an exemplary embodiment, Figure 4 This is a flow chart of another vehicle unlocking method provided by an embodiment of the present application. Figure 4 As shown, the method 400 can be divided into two stages:

[0055] Phase 1: Digital key generation phase, which mainly includes the interaction between the user, terminal 120, vehicle 110 and cloud server. Figure 4 S401 to S418 shown:

[0056] During the production process of vehicle 110, technicians pre-install a public key infrastructure (PKI) certificate chain into the security chip for identifying the vehicle information in subsequent steps and executing S401 to send the vehicle's relevant information and vehicle Bluetooth information to the cloud server through vehicle 110.

[0057] Among them, the vehicle-related information refers to the Vehicle Identification Number (VIN), which consists of 17 characters and includes information such as the vehicle's manufacturer, year, model, body type and code, engine code and assembly location.

[0058] In S402 , the cloud server receives the vehicle-related information and the vehicle's Bluetooth information sent by the vehicle 110 , and stores them for subsequent verification of the vehicle information and information transmission via the stored vehicle's Bluetooth information.

[0059] After purchasing a vehicle, a user can generate a digital key on Terminal 120 by following the following process. In S403, the user triggers the Bluetooth activation button within the vehicle manufacturer's app 1201 on Terminal 120, activating the Bluetooth module on Terminal 120. In S404, Terminal 120 activates its Bluetooth module, ensuring smooth information transmission in subsequent steps.

[0060] In S405 , the terminal 120 sends the information to be verified to the cloud server, so that the server sends the decrypted data to the vehicle and sends the data to be decrypted to the terminal.

[0061] Among them, the information to be verified can represent relevant information of the vehicle, such as one or more of the vehicle's manufacturer, year and model; the information to be verified can also represent the user's identity information, such as one or more of the user's name, age, gender and ID number.

[0062] For example, when the car manufacturer APP1201 is in the pulled-up state, it can jump to the wallet APP1202. The terminal sends vehicle-related information (for example, the vehicle's manufacturer, year and model) and user identity information (for example, the user's name, age, gender and ID number) to the cloud server through the wallet APP1202.

[0063] Continuing with S406, the cloud server receives the information to be verified (e.g., the vehicle's manufacturer, year, and model) and the user's identity information (e.g., name, age, gender, and ID number) sent by the terminal 120 via the wallet app 1202. In S407, the cloud server verifies the received information to be verified and generates the data to be decrypted and the decrypted data based on the verification result.

[0064] The data to be decrypted may represent a public key for unlocking the vehicle, and the decrypted data may represent a private key for unlocking the vehicle.

[0065] Exemplarily, the cloud server verifies the manufacturer, year and model of the received vehicle, and the name, age, gender and ID number of the user, and if the verification is successful, generates the data to be decrypted and the decrypted data according to the verification result.

[0066] In S408, the cloud server sends the decrypted data to the vehicle 110. In S408', the cloud server sends the decrypted data to the terminal 120. The terminal 120 performs interactive verification with the vehicle 110 using a preset protocol included in the wallet app 1202. The preset protocol is the Car Connectivity Consortium (CCC) protocol, but other protocols, such as proprietary protocols used by car manufacturers, are also compatible.

[0067] It should be understood that S408 and S408' are executed by the cloud server at the same time. In other words, the execution order of S408 and S408' is an and relationship.

[0068] Exemplarily, the cloud server may send the decrypted data and the data to be decrypted to the vehicle 110 and the terminal 120 simultaneously.

[0069] In S409, the vehicle 110 receives the decrypted data sent by the cloud server. The decrypted data is sent to the vehicle 110 by the cloud server when it receives the information to be verified (for example, the manufacturer, year and model of the vehicle) and the user's identity information (for example, name, age, gender and ID number) sent by the wallet APP 1202 in the terminal 120.

[0070] In S410, the vehicle 110 receives the decrypted data sent by the server, and in response to the received decrypted data, controls the built-in Bluetooth module set in the vehicle 110 to be in an activated state to establish an information transmission channel between the built-in Bluetooth module and the external Bluetooth module set in the terminal 120.

[0071] The internal Bluetooth module may refer to a Bluetooth module provided in the vehicle 110 , and the external Bluetooth module may refer to a Bluetooth module provided in the terminal 120 . The information transmission channel may transmit data between the terminal 120 and the vehicle 110 .

[0072] For example, in response to receiving the decrypted data sent by the cloud server, the vehicle 110 controls its own built-in Bluetooth module to be in an activated state, thereby establishing an information transmission channel between the built-in Bluetooth module and the external Bluetooth module, so that the information transmission between the vehicle 110 and the terminal 120 can proceed smoothly, thereby providing protection for the vehicle to generate a complete certificate chain.

[0073] In S411, after the wallet APP 1202 in the terminal 120 receives the data to be decrypted sent by the cloud server, it executes S412 to send the data to be decrypted to the vehicle 110, so that the vehicle 110 combines the decrypted data and the data to be decrypted to generate a certificate chain, and verifies the certificate chain to obtain a verification result.

[0074] In an exemplary embodiment, the decrypted data is used to control the built-in Bluetooth module provided in the vehicle 110 to be in an activated state when the vehicle 110 receives the decrypted data, so as to establish an information transmission channel between the built-in Bluetooth module and the external Bluetooth module provided in the terminal 120. The wallet APP 1202 in the terminal 120 sends the data to be decrypted to the vehicle 110 through the information transmission channel, which can ensure that the vehicle can successfully receive the data to be decrypted sent by the terminal.

[0075] Exemplarily, the vehicle 110 receives the data to be decrypted sent by the wallet APP 1202 in the terminal 120. The data to be decrypted is sent to the terminal 120 by the cloud server when it receives the information to be verified (for example, the manufacturer, year and model of the vehicle, and the user's name, age, gender and ID number) sent by the wallet APP 1202 in the terminal 120.

[0076] For example, in S413 , the vehicle 110 receives the data to be decrypted sent by the wallet APP 1202 in the terminal 120 through the established information transmission channel, thereby ensuring that the vehicle can generate a complete certificate chain.

[0077] In S414 , the vehicle 110 combines the decrypted data and the data to be decrypted to generate a certificate chain, and verifies the certificate chain to obtain a verification result.

[0078] Among them, there are two types of verification results: correct verification and incorrect verification. Correct verification means that the vehicle can generate a complete certificate chain in the process of combining the decrypted data and the data to be decrypted; incorrect verification means that the vehicle cannot generate a complete certificate chain in the process of combining the decrypted data and the data to be decrypted.

[0079] If the verification result is correct, S415 is executed, and the vehicle 110 sends the verification result to the terminal 120 through the information transmission channel, so that the terminal generates a digital key.

[0080] Exemplarily, the vehicle 110 sends the correct verification result to the wallet APP 1202 in the terminal 120 through the information transmission channel, so that the wallet APP 1202 in the terminal generates a digital key, thereby providing a guarantee for the terminal to smoothly generate the digital key.

[0081] If the verification result is an error, the digital key generation process is stopped until the user triggers the button for activating Bluetooth in the terminal 120 again in S403 to restart the digital key generation process.

[0082] Continuing to execute S416, the terminal 120 receives the verification result (indicating a correct verification result) sent by the vehicle 110 through the information transmission channel, and generates a digital key according to the correct verification result.

[0083] For example, the wallet APP 1202 in the terminal 120 receives the correct verification result sent by the vehicle 110 through the information transmission channel, and generates a digital key based on the correct verification result, which can be implemented through S417 and S418. In S417, the terminal 120 generates a preset protocol key based on the verification result.

[0084] Among them, the preset protocol key refers to the CCC protocol key generated through the CCC protocol.

[0085] Exemplarily, the wallet APP 1202 in the terminal 120 generates a CCC protocol key through the CCC protocol according to the correct verification result, and if the verification result meets the expected result, executes S418 to generate a digital key according to the preset protocol key.

[0086] Here, the expected result may refer to a correct verification result.

[0087] For example, when the verification result is correct, the wallet APP 1202 in the terminal 120 generates a digital key (i.e., NFC key) based on the CCC protocol key, avoiding the generation of a digital key that cannot unlock the vehicle when the verification result is incorrect, thereby ensuring the accuracy of the generated digital key.

[0088] The above describes the possible implementation process of the digital key generation stage of the embodiment of this application. Next, the second stage of the embodiment of this application: the unlocking stage using the digital key will be introduced. Figure 4 S419~S426 shown in:

[0089] In S419 , based on the communication connection, information is sent from the external Bluetooth module to the internal Bluetooth module so that the vehicle 110 obtains the location of the terminal 120 .

[0090] The communication connection refers to a communication connection established between an external Bluetooth module disposed in the terminal 120 and a built-in Bluetooth module disposed in the vehicle 110. An information transmission channel of the Bluetooth module exists between the vehicle 110 and the terminal 120, and the communication connection may indicate that the information transmission channel is in an activated state.

[0091] The information sent by the terminal 120 may include the location information of the terminal 120 and / or the Bluetooth signal strength, etc., and the information may also include a digital key.

[0092] For example, the wallet APP 1202 in the terminal 120 sends the location information and / or Bluetooth signal strength of the terminal 120 to the built-in Bluetooth module through the external Bluetooth module based on the communication connection, so that the vehicle 110 can obtain the location of the terminal 120, thereby providing a basis for determining the distance between the terminal location and the vehicle location.

[0093] The vehicle 110 can obtain the location of the terminal through S210. As an implementation of S210, S420 is executed. Specifically, in S420, the vehicle 110 receives information sent by the external communication module through the built-in Bluetooth module based on the communication connection to obtain the location of the terminal 120.

[0094] For example, based on the communication connection, the vehicle 110 receives the location information and / or Bluetooth signal strength of the terminal 120 sent by the external communication module through the built-in Bluetooth module, and can obtain the location of the terminal 120, thereby providing a basis for judging the distance between the terminal location and the vehicle location.

[0095] After the vehicle 110 acquires the location of the terminal 120, S220 is executed. As an implementation of S220, S421 is executed. Specifically, in S421, the vehicle 110 calculates the distance between the location of the terminal and the location of the vehicle using ultra-wideband communication technology.

[0096] For example, the vehicle 110 calculates the distance between the location of the terminal 120 and the location of the vehicle 110 according to the UWB technology. Figure 3 The vehicle 110 calculates the distance between the terminal 120's position A, position B and / or position C and its own position B based on the UWB technology, which can make the calculated distance between the terminal's position and the vehicle's position more accurate, and can perform dynamic calculations based on the terminal's position changes to achieve the effect of real-time monitoring of the distance changes between the terminal's position and the vehicle's position. It can also put the vehicle in a low-power state during the distance calculation process, thereby achieving the effect of saving vehicle energy.

[0097] After the vehicle 110 calculates the distance between the terminal's position and the vehicle's position according to the UWB technology, it executes S422 to determine whether the distance satisfies a second preset range.

[0098] The second preset range includes the first preset range, that is, the second preset range is larger than the first preset range. Figure 3 The second preset range represents the range covered by a circle with a distance length AB centered at the position B of the vehicle 110 , which can be recorded as range a. This embodiment of the present application does not limit this.

[0099] Exemplarily, the terminal 120 is at position D, and the distance DB from the vehicle is calculated to be 0.9 meters according to the UWB technology. The vehicle 110 determines whether the distance DB satisfies the range a (ie, the second preset range).

[0100] In an exemplary embodiment, when the distance DB (0.9 meters) satisfies the range a, the vehicle 110 executes S423 to control the preset mode of the vehicle 110 to be in an activated state.

[0101] Among them, the preset mode can represent the vehicle's welcome mode and detection mode, etc. The preset mode can represent one or more modes, and the embodiment of the present application does not limit this.

[0102] Exemplarily, when the distance DB (0.9 meters) of the vehicle 110 satisfies the range a, the welcome mode of the vehicle 110 is controlled to be activated, so that the vehicle can be prepared for unlocking, thereby ensuring the normal progress of automatic unlocking.

[0103] Exemplarily, when the distance DB of the vehicle 110 does not satisfy the range a, the vehicle 110 does not receive the digital key sent to the vehicle 110 by the terminal 120 in S424.

[0104] It should be understood that in S419, the information sent by the terminal 120 to the vehicle 110 may include the digital key, and the digital key generated by the wallet APP 1202 in the terminal is always sent to the vehicle 110 through the communication connection established between the external Bluetooth module of the terminal 120 and the built-in Bluetooth module of the vehicle 110, until the vehicle 110 receives the digital key after determining that the position of the terminal 120 meets the first preset range, and unlocks the vehicle 110 through the received digital key.

[0105] Continuing to execute S425, the vehicle 110 determines whether the distance between the terminal's location and its own location satisfies a first preset range.

[0106] Exemplarily, when vehicle 110 determines that terminal 120 is at position D, the distance DB between the position of terminal 120 and its own position is 0.9 meters. Does the distance DB (0.9 meters) meet range b (ie, the first preset range)?

[0107] When the distance DB (0.9 meters) satisfies the range b, the vehicle 110 executes S426 , and the vehicle 110 receives the digital key sent by the terminal 120 to unlock the vehicle 110 using the digital key.

[0108] Exemplarily, when the distance DB (0.9 meters) of the vehicle 110 satisfies the range b, the vehicle 110 receives the digital key sent by the terminal 120 and automatically unlocks the vehicle using the digital key.

[0109] For example, when the terminal 120 is in a powered-off state, the terminal 120 can use its own NFC module to fit the NFC module provided in the vehicle, thereby establishing a communication connection between the NFC modules so that the digital key can unlock the vehicle.

[0110] exist Figure 4In the provided technical solution, the cloud server receives the information to be verified (vehicle-related information and user identity information) sent by the terminal, verifies the information to be verified, and generates decrypted data sent to the vehicle and the decrypted data sent to the terminal. The vehicle combines the decrypted data with the decrypted data sent by the terminal via the signal transmission channel to generate a certificate chain, verifies the certificate chain, and sends the verification result to the terminal. The establishment of the information transmission channel ensures that the vehicle and the terminal can smoothly receive and send the decrypted data and verification results. In addition, if the verification result is correct, the terminal generates a preset protocol key (CCC protocol key) according to the preset protocol (CCC protocol), and then generates a digital key (NFC key) that can unlock the vehicle based on the preset protocol key. This avoids the generation of a digital key that cannot unlock the vehicle when the verification result is incorrect, thereby ensuring the accuracy of the generated digital key. In addition, by establishing a completed communication connection, the vehicle uses the built-in Bluetooth module arranged in the vehicle to receive information sent by the external communication module arranged in the terminal (for example, the terminal's location information and / or digital key, etc.), so that the vehicle can obtain the terminal's location, thereby providing a basis for the vehicle to determine the distance between the terminal's location and its own location. Next, the vehicle uses UWB technology to calculate the distance between the terminal's position and the vehicle's position, which can improve the accuracy of the calculated distance and can perform dynamic calculations based on the terminal's position changes, thereby achieving the effect of real-time monitoring of the distance changes between the terminal's position and the vehicle's position. It can also put the vehicle in a low-power state during the distance calculation process, thereby saving vehicle energy. In addition, when the calculation result meets the set unlocking condition (first preset range), the vehicle automatically unlocks using the digital key received from the terminal, eliminating the need for the user to activate the smart key for unlocking on the terminal, thereby improving the intelligence and simplicity of the vehicle unlocking process. Furthermore, based on the attribute characteristics of the digital key, when the terminal is in the off state, the terminal's NFC module can be used to fit the NFC module set in the vehicle, thereby establishing a communication connection between the NFC modules, so that the digital key can unlock the vehicle, ensuring the real-time nature of unlocking the vehicle using the digital key.
