[0053] In order to solve the problem that the establishment of wireless connection between devices in the conventional technology depends on manual operation of the user, the embodiments of the present application provide a wireless connection establishment method. Based on the method, the first device can automatically obtain the information of the access point of the second device, such as the identifier and password of the access point, and automatically access the access point of the second device under the premise of ensuring the security of the related devices and data of the user.

As shown in FIG. 1, the device interconnection system 100 can include a first device 110, a second device 120, and a server 130.

[0056] The first device 110 can include a processor, a memory, a communication module, a display screen, a sensor module, and the like. In some embodiments, the first device 110 can further include one or more of the following modules: a charging management module, a power management module, a battery, a speaker, a receiver, a microphone, a camera, and the like, without limitation.

[0057] In the embodiments of the present application, the first device 110 is configured to obtain, from the server 130, information of an access point of the second device 120, such as an identifier and a password of the access point, and access the access point of the second device according to the information of the access point.

[0058] As an example, the first device 110 can connect to the access point of the second device 120 according to the obtained information of the access point of the second device 120 when a certain condition (denoted as "first condition") is met. Illustratively, the first condition includes that the distance between the first device and the second device is less than a first distance threshold. In some embodiments, the first condition can further include other sub-conditions, without limitation.

[0059] The second device 120 is configured to synchronize, to the server 130, information of an access point of the second device 120, such as an identifier and a password of the access point, so as to synchronize, by the server 130, the information of the access point of the second device 120 to devices authorized by the second device 120, such as the first device 110.

[0064] Taking the smart vehicle scenario as an example, the first device is a user device, and the second device is a vehicle machine device on a vehicle. The vehicle machine device is authorized by the user device to obtain the information of the access point of the vehicle machine device, and the user device can obtain the information of the access point of the vehicle machine device.

[0065] For example, the vehicle in the embodiments of the present application can be a vehicle (such as a car, a bus, a subway, a high-speed rail, a motorcycle, a flying car, a train, a jet ski, a ship, an airplane, a drone, and the like), an industrial vehicle (such as a forklift, a trailer, a tractor, and the like), an engineering vehicle (such as an excavator, a bulldozer, a crane, and the like), an agricultural device (such as a mower, a harvester, and the like), a recreational device, a toy vehicle, a boat, a hovercraft, a submarine, an airplane, a helicopter, and the like. The embodiments of the present application do not limit the specific types, modes, and functions of the vehicle.

[0066] Taking the first device 110 shown in FIG. 1 as a user device and the second device 120 as an in-vehicle infotainment device as an example, as an example, refer to FIG. 2, FIG. 2 shows a schematic diagram of an in-vehicle infotainment system architecture provided in an embodiment of the present application. As shown in FIG. 2, the in-vehicle infotainment system 200 can include a user device 210, a vehicle, and a vehicle cloud server 230.

[0067] The vehicle cloud server 230 shown in FIG. 2 is configured to connect with the user device 210 and the in-vehicle infotainment device 220, manage access point information (such as the identification and password of the access point) and vehicle information (such as the vehicle identification number (VIN)) from the in-vehicle infotainment device 220, and manage vehicle owner information (such as the account information of the vehicle owner for the device interconnection application) from the user device 210. The VIN is usually composed of a string of characters (such as 17 characters) and is used to represent information such as the manufacturer, the year, the model, the body type and code, the engine code, and the assembly location of the vehicle.

[0068] By way of example, the identification of the access point can be the name of the wireless local area network corresponding to the access point. By way of example, the identification of the access point can be the service set identifier (SSID) of the access point.

[0069] The user device 210 shown in FIG. 2 is configured to obtain the information of the access point of the in-vehicle infotainment device 220 from the vehicle cloud server 230, such as the identification and password of the access point, and access the access point of the in-vehicle infotainment device 220 according to the information of the access point.

[0070] For example, the user device 210 can perform device scanning to discover the access point of the in-vehicle infotainment device 220, and then send a connection request to the in-vehicle infotainment device 220 to request to connect to the access point of the in-vehicle infotainment device 220, wherein the connection request carries the password of the access point of the in-vehicle infotainment device 220, which is used by the in-vehicle infotainment device 220 to perform verification to determine whether to allow the user device 210 to access the access point of the in-vehicle infotainment device 220.

[0071] As an example, the user device 210 can connect to the access point of the in-vehicle infotainment device 220 according to the obtained information of the access point of the in-vehicle infotainment device 220 when a certain condition (such as a first condition) is met. By way of example, the first condition is met when the distance between the user device 210 and the in-vehicle infotainment device 220 is less than a first distance threshold; or the first condition is met when the distance between the user device 210 and the in-vehicle infotainment device 220 is less than a first distance threshold and / or the vehicle is unlocked (such as the vehicle door is unlocked).

[0072] In some embodiments, the user device 210 is further configured to request the vehicle telematics device 220 to unlock the vehicle, such as unlock the vehicle door, when a second condition is satisfied. For example, the second condition is satisfied when the distance between the user device 210 and the vehicle telematics device 220 is less than a second distance threshold, where the second distance threshold is greater than or equal to the first distance threshold. For example, when the user carries the user device 210 close to the vehicle to which the vehicle telematics device 220 belongs to such that the distance between the user device 210 and the vehicle telematics device 220 is less than the second distance threshold, the user device 210 triggers the unlock request to request the vehicle telematics device 220 to unlock the vehicle.

[0077] The car machine device 220 shown in FIG. 2 is used to synchronize the information of the access point of the car machine device 220, such as the identification and password of the access point, to the car cloud server 230, so as to synchronize the information of the access point of the car machine device 220 to the devices authorized by the car machine device 220, such as the user equipment 210, through the car cloud server 230.

[0078] In some embodiments, the car machine device 220 is also used to verify the connection request when receiving the connection request from the user equipment 210, such as verifying whether the password carried in the connection request matches the access point of the car machine device 220, etc., and allowing the user equipment 210 to connect to the access point of the car machine device 220 when the verification is passed.

[0079] In some embodiments, the car machine device 220 is also used to verify the unlocking request when receiving the unlocking request from the user equipment 210, such as verifying whether the user equipment 210 has the unlocking authority of the vehicle to which the car machine device 220 belongs, etc., and unlocking the vehicle, such as unlocking the door, when the verification is passed.

[0080] In some embodiments, the car machine device 220 is further configured to, when the user modifies the identification and / or password of the access point of the car machine device 220, disconnect the first wireless connection between the user equipment 210, synchronize the latest identification and / or the latest password of the modified access point to the car cloud server 230. In this way, the user equipment 210 can send a connection request to the car machine device 220 again based on the latest identification and / or the latest password of the access point obtained from the car cloud server 230. Not only can the user's related needs for security and the like be met, but the user can also be unaware of the reconstruction of the wireless connection (e.g., the reconstructed wireless connection is referred to as a "third wireless connection", and the third wireless connection is of the same type as the first wireless connection, such as both being Wi-Fi connections), ensuring the normal operation of related car machine interconnection services.

[0081] As an example, the car machine device 220 shown in FIG. 2 can include, but is not limited to, a processor, a screen, a communication module, and the like. The processor is configured to run various tasks of car-mounted applications, such as, but not limited to, device interconnection applications, video applications, music applications, navigation applications, and the like, without limitation. The screen is configured to display interfaces (e.g., application interfaces). The communication module is configured to communicate with other devices, such as the car cloud server 230, the user equipment 210, and the like.

[0082] In the embodiments of the present application, the communication module includes an access point, such as a wireless access point, e.g., a Wi-Fi access point. The processor can determine whether to allow the user equipment 210 to access the access point by verifying the connection request from the user equipment 210. After the user equipment 210 accesses the access point of the car machine device 220 to implement device interconnection, the user equipment 210 can communicate through the first wireless connection between the two to implement related car machine interconnection functions, such as implementing functions of controlling components or domain controllers of a vehicle to which the car machine device 220 belongs, such as doors, windows, seats, lights, wipers, trunks, air conditioners, multimedia players, screens, and the like, through the user equipment 210.

[0083] As an example, please refer to FIG. 3, which shows a device interconnection process diagram provided by the embodiments of the present application, taking the car machine interconnection system in the smart car scenario shown in FIG. 2 as an example, and combining the internal structure of the user equipment 210 and the car machine device 220. As shown in FIG. 3, the car machine interconnection system 200 can include the user equipment 210, the car machine device 220, and the car cloud server 230.

[0084] The vehicle cloud server 230 is configured to connect with the user device 210 and the vehicle machine device 220, manage the access point information (e.g., the identification and password of the access point) from the vehicle machine device 220, and manage the vehicle information (e.g., the VIN of the vehicle) from the user device 210. The user device 210 is authorized to obtain the access point information of the vehicle machine device 220.

[0085] As shown in FIG. 3, the vehicle can include the vehicle machine device 220, a wireless vehicle key controller, one or more domain controllers, vehicle components, and the like. The domain controllers can include one or more of an intelligent driving domain controller, an instrument domain controller, a cockpit domain controller, a chassis domain controller, a power domain controller, a body domain controller, and the like. The vehicle machine device 220 can include a micro control unit (MCU), a wireless module, and a Wi-Fi module as shown in FIG. 3.

[0086] As shown in FIG. 3, the vehicle machine device 220 is installed with an application of device interconnection and an application of vehicle cloud connection.

[0087] As an example, as shown in S301 of FIG. 3, the vehicle cloud connection application in the vehicle machine device 220 can synchronize the access point information (e.g., the identification and password of the access point) of the vehicle machine device 220 and the vehicle information (e.g., the VIN of the vehicle) to the vehicle cloud server 230. For example, the vehicle cloud connection application can synchronize the access point information of the vehicle machine device 220 to the vehicle cloud server 230 after the user sets or modifies the access point information of the vehicle machine device 220.

[0088] As shown in FIG. 3, the user device 210 includes a wireless module and a Wi-Fi module, which are configured to support the communication between the user device 210 and other devices (e.g., the vehicle cloud server 230 or the vehicle machine device 220). As an example, the wireless module can include one or more of a Bluetooth module, a near-field communication (NFC) module, an ultra-wide bandwidth (UWB) module, and the like as shown in FIG. 3.

[0089] As shown in FIG. 3, the user device 210 is installed with an application of device interconnection and an application of wireless vehicle key.

[0090] The application of device interconnection in the user device 210 is configured to obtain the access point information (e.g., the identification and password of the access point) of the vehicle machine device 220 from the vehicle cloud server 230, and trigger the interaction between the user device 210 and the vehicle machine device 220 according to the relevant operation of the user, so as to realize the relevant vehicle machine interconnection function.

[0091] As an example, as shown in S302 in FIG. 3, the device interconnection application in the user equipment 210 can obtain the information of the access point of the car machine device 220 from the car cloud server 230 that provides services for it, such as the identification and password of the access point.

[0092] The wireless car key application in the user equipment 210 is used to unlock the vehicle, and the wireless car key application can include but is not limited to a data car key application and the like.

[0093] As an example, as shown in S303 in FIG. 3, the wireless car key application in the user equipment 210 can send a request to unlock the car machine device 220 through the wireless module to the car machine device 220 to unlock the vehicle to which the car machine device 220 belongs, such as unlocking the car door as shown in FIG. 3.

[0094] For example, when the second condition is met, the wireless car key application in the user equipment 210 can request the car machine device 220 to unlock the door of the vehicle to which the car machine device 220 belongs through one or more of the Bluetooth module, the NFC module or the UWB module. For example, the second condition is met, such as the distance between the user equipment 210 and the car machine device 220 is less than a second distance threshold. For example, when the user carries the user equipment 210 close to the vehicle to which the car machine device 220 belongs to the distance between the car machine device 220, the user equipment 210 triggers a request to unlock the vehicle, requesting the car machine device 220 to unlock the vehicle. Alternatively, the second condition is met, such as the user equipment 210 detecting the user's unlock operation, such as but not limited to the unlock operation triggered by the user through the wireless car key application or the device interconnection application in the user equipment 210, or other forms of unlock operation, without specific limitation.

[0095] The embodiments of the present application do not limit the specific execution order of S303 and S301 or S302, for example, S303 can occur before S301, or it can occur after S301; and S303 can occur before S302, or it can occur after S302, without limitation.

[0096] As an example, as shown in S304 in FIG. 3, the wireless car key controller of the car machine device 220 can execute a vehicle unlocking operation, such as unlocking the car door, through the body domain controller according to the unlock request received by the wireless module of the car machine device 220.

[0097] For example, the wireless car key controller can verify the unlock request, such as verifying whether the user equipment 210 has the unlocking permission of the vehicle to which the car machine device 220 belongs, and the like, and executes the vehicle unlocking operation through the body domain controller when the verification is passed.

[0098] As an example, as shown in S305 of FIG. 3, after obtaining the information of the access point of the vehicle machine device 220, the device interconnection application in the user equipment 210 can send a connection request to the vehicle machine device 220 through the Wi-Fi module according to the obtained information of the access point of the vehicle machine device 220 to request to connect to the access point of the vehicle machine device 220 when the first condition is met. The connection request can carry the password of the access point of the vehicle machine device 220, which is used by the vehicle machine device 220 to verify whether to allow the user equipment 210 to access the access point of the vehicle machine device 220. For example, the first condition is that the distance between the user equipment 210 and the vehicle machine device 220 is less than a first distance threshold. For another example, the first condition is that the distance between the user equipment 210 and the vehicle machine device 220 is less than the first distance threshold and / or the vehicle is unlocked (e.g., the door of the vehicle is unlocked as shown in FIG. 2). The first distance threshold is less than or equal to the second distance threshold.

[0099] As an example, as shown in S306 of FIG. 3, the Wi-Fi module of the vehicle machine device 220 can allow the user equipment 210 to connect to the access point of the vehicle machine device 220 according to the received connection request to establish a Wi-Fi connection between the user equipment 210 and the vehicle machine device 220. For example, the Wi-Fi module of the vehicle machine device 220 can verify the connection request, such as verifying whether the password carried in the connection request matches the password of the access point of the vehicle machine device 220, and allow the user equipment 210 to connect to the access point of the vehicle machine device 220 when the verification is passed.

[0100] As an example, as shown in S307 of FIG. 3, after the user equipment 210 accesses the access point of the vehicle machine device 220 to establish a Wi-Fi connection between the user equipment 210 and the vehicle machine device 220, the user equipment 210 and the vehicle machine device 220 can perform vehicle machine interconnection related communication through the Wi-Fi connection to implement related vehicle machine interconnection functions, such as implementing the function of the user equipment 210 controlling the door, window, seat, light, wiper, trunk, air conditioner, multimedia player, screen, etc. of the vehicle to which the vehicle machine device 220 belongs.

[0101] It can be understood that the structure shown in FIG. 3 does not constitute a specific limitation on the structure of the user equipment 210 and the vehicle machine device 220. In other embodiments of the present application, the user equipment 210 or the vehicle machine device 220 can include more or fewer components than FIG. 3, or combine certain components, or split certain components, or different component arrangements. The components of FIG. 3 can be implemented in hardware, software, or a combination of software and hardware.

[0102] As an example, the user device described in the embodiments of the present application can include, but is not limited to, a smart phone, a netbook, a tablet computer, a smart board, a smart pen, a smart watch, a smart bracelet, a phone watch, smart glasses, a smart camera, a palm computer, a vehicle-mounted computer, a PC, a PDA, a PMP, an AR / VR device, a smart television, a projection device, or a motion game machine in a human-computer interaction scene, etc. Alternatively, the user device can also be other types or structures of electronic devices, which are not limited in the present application.

[0103] In some embodiments of the present application, the plurality of first devices can log in to the same user account of the device interconnection application, and the user account is authorized by the second device, that is, the plurality of first devices are authorized to obtain the information of the access point of the second device, so that the plurality of first devices can obtain the information of the access point of the second device from the server, and access the access point of the second device according to the information of the access point.

[0104] In some embodiments of the present application, the plurality of first devices can log in to different user accounts of the device interconnection application, and the different user accounts are authorized by the same second device, that is, the plurality of first devices are authorized to obtain the information of the access point of the same second device, so that the plurality of first devices can obtain the information of the access point of the second device from the server, and access the access point of the second device according to the information of the access point.

[0105] In some embodiments of the present application, the same user account of the device interconnection application can be authorized by a plurality of second devices, that is, the plurality of first devices are authorized to obtain the information of the access point of the plurality of second devices, so that the first device logged in to the user account can obtain the information of the access point of the plurality of second devices from the server, and connect to the access point of each second device according to the information of the access point of the plurality of second devices.

[0106] Taking the first device as a user device, the second device as an in-vehicle infotainment device, and the server as an example, as shown in Table 1, a plurality of user devices (such as a first user device and a second user device) can log in to the same user account A of the device interconnection application, and the user account A is authorized by a vehicle 1 with a vehicle identification number VIN1, so that the plurality of user devices (such as the first user device and the second user device) logged in to the user account A can obtain the information (such as SSID1 and password1) of the access point of the in-vehicle infotainment device of the vehicle 1 from the vehicle cloud server, and access the access point on the vehicle 1 according to the information of the access point.

[0107] Table 1

[0108] As an example, as shown in Table 2 below, multiple user devices can log in different user accounts of the device interconnection application, such as a first user device logs in a user account A and a second user device logs in a user account B, and the user account A and the user account B are both authorized for a vehicle 1 with a vehicle identification code VIN1, and thus the first user device and the second user device logged in the user account A and the user account B respectively can obtain information (such as SSID1 and password1) of an access point of a vehicle infotainment device of the vehicle 1 from a vehicle cloud server and access the access point on the vehicle 1 according to the information of the access point.

[0109] Table 2

[0110] As an example, as shown in Table 3 below, the same user account A of the device interconnection application can be authorized for a vehicle 1 with a vehicle identification code VIN1 and a vehicle 2 with a vehicle identification code VIN2, and thus one or more user devices (such as a user device A and a user device B shown in Table 3) logged in the user account A can obtain information (such as SSID1 and password1) of an access point of a vehicle infotainment device of the vehicle 1 and information (such as SSID2 and password2) of an access point of a vehicle infotainment device of the vehicle 2 from a vehicle cloud server and connect to the access point on the vehicle 1 and / or the vehicle 2 based on the obtained information.

[0111] Table 3

[0112] The wireless connection establishment method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0113] As an example, please refer to FIG. 4, which shows a flow chart of a wireless connection establishment method provided by an embodiment of the present application. As shown in FIG. 4, the wireless connection establishment method provided by the embodiment of the present application can be implemented based on S401-S403:

[0114] S401: The second device sends first access point information to a server, and the first access point information includes an identifier and a password of an access point of the second device.

[0115] As an example, the identifier of the access point is, for example, the SSID of the access point.

[0116] As an example, after the second device sends the first access point information to the server, the server can associate the second device with a user account of a device interconnection application authorized by a user, for example, bind the second device to the user account of the device interconnection application authorized by the user. In this way, the user account is authorized for the second device, and a first device logged in the user account is authorized to obtain information of the access point of the second device from the server. The device interconnection application is served by the server.

[0117] S402: The first device acquires the first access point information from the server.

[0118] The first device logs in a user account of a device interconnection application, and the user account is authorized by the second device. That is, the first device logged in the user account is authorized to acquire the information of the access point of the second device (including the first access point information) from the server.

[0119] As an example, the first device can acquire the first access point information from the server when the device interconnection application of the above-mentioned user account is started, and / or the first device can periodically acquire the first access point information from the server.

[0120] S403: When the first condition is met, the first device connects to the access point of the second device according to the first access point information.

[0121] As an example, when the first condition is met, the first device can scan to discover the identifier of the access point of the second device included in the first access point information, and send a first connection request to the access point corresponding to the identifier to request to connect to the access point of the second device. The first connection request carries a password, which is used for the second device to perform access-related verification.

[0122] As an example, the second device can verify the password carried in the first connection request, such as verifying whether the password carried in the first connection request matches the access point of the second device, and the like, and allow the first device to connect to the access point of the second device and establish a first wireless connection, such as a Wi-Fi connection, with the first device when the verification is passed.

[0123] As an example, the first condition is met, such as the distance between the first device and the second device is less than a first distance threshold.

[0124] Taking the second device as an example, the second device is a car machine device on a vehicle, and as an example, the first condition is met, such as the distance between the first device and the second device is less than a first distance threshold, and / or the vehicle is unlocked.

[0125] The first device acquires the first access point information of the second device from the server as an example in FIG. 4. In actual application, the specific time for the first device to acquire the first access point information from the server is not limited. For example, the first device can also acquire the first access point information from the server when the first condition is met.

[0126] Based on the wireless connection establishment method shown in FIG. 4, the first device can automatically obtain the information of the access point of the second device, such as the identification and password of the access point, and then automatically access the access point of the second device according to the information of the access point when there is a need for wireless connection establishment. This scheme can greatly simplify user operation and realize automatic wireless connection establishment between devices. Moreover, since the first device has the permission to obtain the information of the access point of the second device from the server, the security of user-related devices and data can also be ensured. In addition, this scheme can be applied to devices with different capabilities and has strong compatibility.

[0127] In some embodiments, if the information of the access point of the second device changes, for example, if the user modifies the identification and / or password of the access point of the second device, the second device can update the information of the modified access point, such as the second access point information, to the server in time, where the second access point information includes the latest identification and the latest password of the access point of the second device modified by the user. When the user modifies the identification and / or password of the access point of the second device, the first wireless connection (such as Wi-Fi connection) previously established between the first device and the second device based on the first access point information may be disconnected, in which case the first device can obtain the updated second access point information from the server and reconnect to the access point of the second device according to the second access point information. For example, the first device can scan to discover the latest identification of the access point of the second device included in the second access point information, and send a second connection request to the access point corresponding to the latest identification to request connection to the access point of the second device, where the second connection request carries the latest password, which is used by the second device for access-related verification. Correspondingly, after receiving the second connection request from the first device, the second device verifies the latest password carried in the second connection request, such as whether the latest password carried in the second connection request matches the access point of the second device, and allows the first device to connect to the access point of the second device and establish a third wireless connection with the first device when the verification is passed. In this way, through the timely update of the information of the access point of the second device, the problem of wireless connection establishment caused by the change of the information of the access point can be solved, and the first device can always establish wireless connection between devices automatically under the premise of simplifying user operation, and the security of user-related devices and data can be ensured.

[0128] As an example, the server can actively send the second access point information to the first device when the identification and / or password of the access point is updated.

[0129] As an example, the first device can send an access point update request to the server to request the latest access point information when the first wireless connection with the second device is disconnected, and the server can send the second access point information to the first device according to the request of the first device.

[0130] The specific timing, trigger party, trigger condition, etc. of the first device obtaining the second access point information from the server are not limited in the embodiments of the present application.

[0131] In some embodiments, after the first device establishes a first wireless connection, such as a Wi-Fi connection, with the second device, the first device can perform device interconnection related communication through the first wireless connection between the first device and the second device, such as supporting the user to control the second device through the first device to implement related device interconnection functions.

[0132] As an example, the method shown in FIG. 4 can be applied in a smart car scenario, where the first device is a user device and the second device is an in-vehicle infotainment device. By way of example, refer to FIG. 5, which shows a flowchart of a method for establishing a wireless connection for device interconnection, taking the first device as a user device, the second device as an in-vehicle infotainment device, and the server as a car cloud server as an example.

[0133] As shown in FIG. 5, in the smart car scenario, the method for establishing a wireless connection for device interconnection can be implemented based on S501-S508.

[0134] S501: The in-vehicle infotainment device sends first access point information to the car cloud server.

[0135] The first access point information includes the identifier and password of the access point of the in-vehicle infotainment device.

[0136] As an example, the identifier of the access point is, for example, the SSID of the access point.

[0137] As an example, after the in-vehicle infotainment device sends the first access point information to the car cloud server, the car cloud server can associate the in-vehicle infotainment device with the user account of the device interconnection application authorized by the user, for example, bind the in-vehicle infotainment device to the user account of the device interconnection application authorized by the user. In this way, the user account is authorized by the in-vehicle device, and the user device logged in the user account is authorized to obtain the information of the access point of the in-vehicle infotainment device from the car cloud server. The device interconnection application is served by the car cloud server.

[0138] In some embodiments, the in-vehicle infotainment device can also send vehicle information, such as the VIN of the vehicle to which the in-vehicle infotainment device belongs, to the car cloud server, for the car cloud server to bind the vehicle and the user account when authorizing the user account.

[0139] S502: The user device obtains the first access point information from the car cloud server.

[0140] For specific details of S502, refer to the description of S402 above, which will not be repeated here.

[0141] S503: The user device sends, to the vehicle device, an unlock request via a second wireless connection when the second condition is met.

[0142] As an example, the user device is installed with a wireless car key application, which can trigger the user device to send, to the vehicle device, an unlock request via a second wireless connection when the second condition is met, to request the vehicle device to unlock a vehicle to which the vehicle device belongs. Exemplarily, the second wireless connection can include but is not limited to one or more of the following: a Bluetooth connection, an NFC connection, a UWB connection, etc.

[0143] As an example, the second condition is met when it is detected that the distance between the first device and the vehicle device is less than a second distance threshold, where the second distance threshold is greater than or equal to the first distance threshold.

[0144] As an example, the second condition is met when a user's unlock operation is detected, such as but not limited to an unlock operation triggered by the user via the wireless car key application or the device interconnection application in the user device, or other forms of unlock operations, without specific limitation.

[0145] S504: The vehicle device verifies the unlock request, and unlocks the vehicle when the verification is passed.

[0146] As an example, the verification of the unlock request by the vehicle device includes but is not limited to verifying whether the user device has the unlock permission for the vehicle to which the vehicle device belongs, etc.

[0147] For example, if the wireless car key application in the user device is previously bound to the vehicle, the user device has the unlock permission for the vehicle; if the wireless car key application in the user device is not previously bound to the vehicle, the user device does not have the unlock permission for the vehicle, where the binding of the wireless car key application in the user device to the vehicle can be performed according to the user's setting operation or authorization.

[0148] As an example, the unlocking of the vehicle by the vehicle device can include but is not limited to unlocking the vehicle door, etc.

[0149] The embodiments of the present application do not limit the specific sequence of the execution of S502 by the user device and S503-S504 by the user device, for example, S502 can occur before S503-S504, can be performed synchronously with S503 or S504, can occur after S503 and before S504, or can occur after S504, without specific limitation.

[0150] S505: The user device scans to discover an access point of the vehicle device when the first condition is met.

[0151] The first connection request includes a password of an access point of the car machine device in the first access point information, and the password is used for the car machine device to perform verification to determine whether to allow the user equipment to access the access point of the car machine device.

[0152] As an example, the first condition is satisfied, such as the distance between the user equipment and the car machine device being less than a first distance threshold, wherein the first distance threshold is less than or equal to the second distance threshold.

[0153] As an example, the first condition is satisfied, such as the distance between the user equipment and the car machine device being less than a first distance threshold and / or the vehicle to which the car machine device belongs being unlocked (such as the car door being unlocked).

[0154] S506: The user equipment sends a first connection request to the scanned access point of the car machine device.

[0155] S507: The car machine device performs verification on the first connection request.

[0156] As an example, the car machine device can perform verification on the password carried in the first connection request, such as verifying whether the password carried in the first connection request matches the access point of the car machine device, and the like, and allows the user equipment to connect to the access point of the car machine device and establish a first wireless connection, such as a Wi-Fi connection, with the user equipment when the verification is passed.

[0157] S508: The car machine device establishes a first wireless connection with the first device when the verification on the first connection request is passed.

[0158] In some embodiments, after the user equipment establishes a first wireless connection, such as a Wi-Fi connection, with the car machine device, the user equipment can perform car machine related communication through the above-mentioned first wireless connection between the user equipment and the car machine device, such as supporting the user to control the vehicle to which the car machine device belongs through the user equipment, to realize related car machine interconnection functions, such as functions of controlling components or domain controllers of the vehicle to which the car machine device belongs, such as doors, windows, seats, lights, wipers, trunks, air conditioners, multimedia players, screens, and the like, by the user equipment.

[0159] Based on the wireless connection establishment method in the intelligent vehicle scenario shown in FIG. 5, the user equipment can automatically unlock the vehicle when approaching the vehicle; and the vehicle device can store the information of the access point through the vehicle cloud server, so that the user equipment authorized by the vehicle device can automatically obtain the information of the access point of the vehicle device from the vehicle cloud server, such as the identification and password of the access point, and then automatically access the access point of the vehicle device according to the information of the access point when there is a wireless connection establishment demand, for example, automatically access the access point of the vehicle device according to the information of the access point when the user equipment approaches the vehicle. This scheme can greatly simplify user operation and realize the non-conscious unlocking and non-conscious Wi-Fi connection of the user equipment when the user equipment approaches the vehicle. Moreover, since the user equipment has the permission to obtain the information of the access point of the vehicle device from the vehicle cloud server, the security of the user-related equipment and data can also be ensured. In addition, this scheme can be applied to devices with different capabilities and has strong compatibility.

[0160] In some embodiments, as shown in FIG. 6, after S508, S509-S514 can also be included:

[0161] S509: When the information of the access point of the vehicle device changes, the vehicle device sends second access point information to the vehicle cloud server.

[0162] The second access point information includes the latest identification and the latest password of the access point of the vehicle device.

[0163] As an example, the change of the information of the access point of the vehicle device can be caused by the user modifying the identification and / or password of the access point of the vehicle device.

[0164] S510: The user equipment obtains the second access point information from the vehicle cloud server.

[0165] As an example, the vehicle cloud server can actively send the second access point information to the user equipment when the identification and / or password of the access point is updated.

[0166] As an example, the user equipment can send an access point update request to the vehicle cloud server when the first wireless connection with the vehicle device is disconnected, to request to obtain the latest information of the access point, and the vehicle cloud server can send the second access point information to the user equipment according to the request of the user equipment.

[0167] The specific timing, trigger party, trigger condition, etc. of the user equipment obtaining the second access point information from the vehicle cloud server are not limited in the embodiments of the present application.

[0168] S511: The user equipment scans to discover the access point of the vehicle device.

[0169] S512: The user equipment sends a second connection request to the access point of the scanned vehicle infotainment device.

[0170] The second connection request includes the latest password of the access point of the vehicle infotainment device in the second access point information, and the latest password is used by the vehicle infotainment device to verify whether to allow the user equipment to access the access point of the vehicle infotainment device.

[0171] S513: The vehicle infotainment device verifies the second connection request.

[0172] S514: The vehicle infotainment device establishes a third wireless connection with the first device when the second connection request is verified.

[0173] As an example, the vehicle infotainment device can verify the latest password carried in the second connection request, such as verifying whether the password carried in the second connection request matches the access point of the vehicle infotainment device, and the like, and allows the user equipment to connect to the access point of the vehicle infotainment device when the verification is passed, and re-establishes a third wireless connection of the same category as the first wireless connection, such as a Wi-Fi connection, with the user equipment.

[0174] In this way, through the timely updating of the information of the access point of the vehicle infotainment device, the problem of wireless connection failure caused by the change of the information of the access point can be solved, and the wireless connection between devices can be established automatically under the premise of simplifying user operation, and the security of user-related devices and data is ensured.

[0175] The present application FIG. 5 and FIG. 6 introduce that the user equipment automatically accesses the access point of the vehicle infotainment device according to the information of the access point of the vehicle infotainment device, and then performs subsequent vehicle control to realize the related vehicle infotainment interconnection function. In actual application, the number of user equipment that obtains the information of the access point of a vehicle infotainment device from the vehicle cloud server is not limited, and the number of vehicle infotainment devices authorized to a user equipment is also not limited. In this way, not only can multiple user equipment and vehicle devices be connected without sensing when multiple people ride a vehicle, but also can support the connection without sensing between user equipment and vehicle devices on different vehicle infotainment devices when the user rides different vehicles, and improve user experience.

[0176] As an example, assuming that the user account A shown in Table 1 is authorized for the vehicle 1 with the vehicle identification code VIN1, then the first user equipment and the second user equipment logged in the user account A can obtain the information of the access point of the vehicle infotainment device of the vehicle 1 (such as SSID1 and password1) from the vehicle cloud server, and access the access point on the vehicle 1 according to the information of the access point, respectively.

[0177] As another example, assuming that user account A and user account B shown in Table 2 are authorized for vehicle 1 with vehicle identification code VIN1, the first user device and the second user device logged in with user account A and user account B respectively can obtain the information (such as SSID1 and password1) of the access point of the infotainment device of vehicle 1 from the vehicle cloud server, and access the access point on vehicle 1 according to the information of the access point.

[0178] As another example, assuming that user account A shown in Table 3 is authorized for vehicle 1 with vehicle identification code VIN1, and is also authorized for vehicle 2 with vehicle identification code VIN2, the first user device and the second user device logged in with user account A can not only obtain the information (such as SSID1 and password1) of the access point of the infotainment device of vehicle 1 from the vehicle cloud server, but also obtain the information (such as SSID2 and password2) of the access point of the infotainment device of vehicle 2 from the vehicle cloud server, and then connect to the access point on vehicle 1 based on the information (such as SSID1 and password1) of the access point of the infotainment device of vehicle 1, and connect to the access point on vehicle 2 based on the information (such as SSID2 and password2) of the access point of the infotainment device of vehicle 2.
