[0027] It should also be noted that in the embodiments of the present application, the collection, use, processing and storage of application information are all subject to the user's permission and must comply with the regulations of the region.

[0028] The present application provides a signal-to-service method, which can be applied to an electronic device, which may be a server, a vehicle or a main controller of the vehicle, or a combination of one or more of the above.

[0029] In some embodiments, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms.

[0030] Among them, the above-mentioned server may specifically include a host manufacturer's cloud backend server, which is a cloud service platform maintained by the vehicle manufacturer and is responsible for managing and processing various data and service requests from the vehicle and its external devices.

[0031] Figure 1 The signal-to-service method of the present application is specifically shown, and the method can be applied to a signal-to-service system including a main controller of a vehicle and a server, and the method includes:

[0032] Step S110: The target external device sends SDK authentication information to the main controller of the vehicle.

[0033] Among them, the target external device can be a navigation device, a game console, an in-vehicle air purification device, or other device that can provide services in the vehicle. When it wants to establish a connection with the vehicle, it needs to generate SDK authentication information through the authentication software development kit corresponding to the target external device, namely, the authentication SDK (Software Development Kit).

[0034] The SDK authentication information usually includes one or more of the following: the identity of the target external device, authentication information generated by a specific algorithm module in the authentication SDK, device information, and an initial key, which are used to prove the legitimacy of the target external device and determine the access rights of the target external device. After receiving this information, the vehicle's main controller will start the authentication process.

[0035] The authentication SDK of the target external device is applied for in advance by the target external device to a server (e.g., a cloud backend server of the OEM, a backend server of a vehicle service provider, or a backend server of a third-party organization that is specifically responsible for managing the vehicle access platform). The authentication SDK may include a device ID for identifying the type of the target external device, a specific algorithm module for encrypting and decrypting authentication information, an initial key for verifying the device identity of the target external device, and a TLV value (Type-Length-Value) for defining the type, length, and value of the signal of the target external device.

[0036] Among them, the main controller can receive the SDK authentication information sent by the target external device through an appropriate communication protocol (such as CAN bus, Ethernet, Bluetooth, etc.). In the embodiment of the present application, the communication protocol adopted can be the CAN bus communication protocol.

[0037] Step S120: The main controller of the vehicle sends SDK authentication information to the server.

[0038] In one possible implementation, the main controller of the vehicle may forward the SDK authentication information to the server upon receiving the SDK authentication information, so that the server may authenticate the target external device according to the SDK information.

[0039] In another possible implementation, the main controller of the vehicle may also add the vehicle identification to the SDK authentication information after receiving the SDK authentication information, and send the authentication information with the vehicle identification added to the server, so that the subsequent server can ensure that the authentication request of a target external device is for a specific vehicle, and after authenticating the target external device, send the authentication result to the terminal associated with the vehicle identification, and may also send the information associated with the target external device to the terminal associated with the vehicle identification, such as the multiple services that the target external device can provide.

[0040] The vehicle's main controller and the server can communicate via mobile cellular communication (such as 4G or 5G), wifi communication, satellite communication or Ethernet communication, etc. For example, the main controller can send the SDK authentication information to the server via 4G / 5G, Wi-Fi, Ethernet and other communication technologies.

[0041] Step S130: the server authenticates the target external device based on the SDK authentication information to obtain an authentication result of the target external device.

[0042] Among them, when the background server authenticates the received SDK authentication information, it specifically includes verifying the device ID, authentication information and initial secret key of the target external device. Specifically, it can be checked whether the device ID of the target external device is in the known legal device list. If it is, the authentication is passed, otherwise the authentication fails; the authentication information is encrypted and decrypted using a specific short-code module in the authentication SDK corresponding to the target external device to ensure the integrity and authenticity of the information. If both the encryption and decryption verifications are passed, the authentication information is authenticated. If there is an encryption or decryption verification failure, the authentication information fails; check whether the initial secret key in the SDK authentication information is consistent with the initial secret key in the SDK authentication of the target device. If they are consistent, the initial key verification is passed, otherwise the verification fails.

[0043] It is worth mentioning that when the device ID, authentication information and initial key are all authenticated, the target external device is authenticated. If the device ID, authentication information and initial key fail to authenticate, the target external device is authenticated.

[0044] In some scenarios, if the vehicle ID of the vehicle is added to the SDK authentication information, the vehicle ID can also be verified, such as checking whether the vehicle ID corresponding to the vehicle stored in the server is consistent with the vehicle ID added to the SDK authentication information. In this case, if they are consistent, and the device ID, authentication information, and initial key are all authenticated, the target external device is authenticated. If they are inconsistent or there is an authentication failure in the device ID, authentication information, and initial key, the target external device is authenticated. Failure.

[0045] Step S140: The server returns the authentication result to the main controller of the vehicle.

[0046] Among them, the server can return the authentication results to the main controller through communication technologies such as 4G / 5G, Wi-Fi, and Ethernet.

[0047] Step S150: When the main controller of the vehicle determines that the authentication result indicates that the authentication is successful, it confirms that the target external device is legitimate and sends the authentication result to the target external device, so that the target external device confirms that it is connected to the vehicle when it confirms that the received authentication result is successful.

[0048] Specifically, when receiving the authentication result, the main controller can parse the authentication result to obtain the authentication status (such as authentication passed or authentication failed). If the authentication result indicates that the authentication is passed, the main controller can also record the relevant information of the target external device, such as device ID, device type, device name, etc., update the status of the target external device to "legal" or "authenticated", and record it in the device management table.

[0049] If it is determined that the authentication result indicates an authentication failure, the main controller may also record an error log, and send a notification of authentication failure to the target external device, thereby terminating the access process.

[0050] The main controller can specifically send the authentication result to the target external device through a communication protocol (such as CAN bus, Ethernet, Bluetooth, etc.).

[0051] Step S160: The main controller of the vehicle receives a first device signal sent by the target external device after confirming that the target external device is connected to the vehicle.

[0052] The target external device can parse the authentication result and obtain the authentication status (such as authentication passed or authentication failed). If the authentication status is authentication passed, the target external device confirms that it has accessed the vehicle. If the authentication status is authentication failed, the target external device can record an error log, display a prompt message of authentication failure, and terminate the access process.

[0053] Among them, after confirming that the authentication is passed, the target external device can also update its own status to "connected".

[0054] The first device signal of the target device may be one of multiple device signals of the target device. Each device signal of the target device may be preconfigured or generated based on signal details of multiple initial signals of the target external device and the type of service provided by each initial signal.

[0055] Among them, each device signal may specifically include signal details, such as signal name, signal value, signal type (such as integer, floating point number, Boolean value, etc.), signal description, cycle time, etc., and may also include a signal representation value (TLV value) used to describe the signal format, a method identifier / event identifier used to describe a specific method or event in the service corresponding to the device signal, and one or more of the service type corresponding to the signal.

[0056] In one possible implementation, different external devices may have different device signal identifiers, such as CANID, etc. The above device signal may be obtained by splicing based on a preset initial signal and device signal identifier.

[0057] Step S170: The main controller of the vehicle converts the first device signal into a first service according to a preset correspondence between the device signal of the target external device and the service, and publishes the first service.

[0058] The preset correspondence stores a plurality of device signals of the target external device and services corresponding to each device signal. The service corresponding to each device signal may be a service composed of one or more of Getter, Setter, Notifier, etc.

[0059] When receiving the first device signal, the main controller may match the first device signal with a plurality of device signals included in the preset corresponding relationship, thereby finding the first service corresponding to the first device signal.

[0060] In one possible implementation, the correspondence between device signals and services corresponding to different external devices can be stored in different databases or different storage locations of the vehicle, that is, databases or storage locations corresponding to different external devices are set in the main controller, and the target external device can also send the device identification of the target external device while sending the first device signal, so that the main controller of the vehicle can find the corresponding database or storage location according to the device identification, and find the first service corresponding to the first device signal from the preset correspondence stored in the database or storage location corresponding to the device identification.

[0061] Through the above implementation, the main controller can quickly locate the corresponding database or storage location according to the device identification, thereby improving the query efficiency.

[0062] In another possible implementation, the device signal of each external device is unique, that is, the correspondence between the device signals and services of multiple external devices can be stored in the same database or storage location of the vehicle, so that the vehicle's tracking controller can directly search for the first service corresponding to the first device signal from the preset correspondence stored in the above-mentioned database or storage location according to the first device signal.

[0063] Through the above implementation, since the correspondence between the device signals and services of all external devices is stored in the same database or storage location, and only one database or storage location needs to be maintained, data management is simplified while saving storage resources.

[0064] By adopting the above-mentioned signal-to-service method of the present application, the main controller receives SDK authentication information sent by the target external device; sends the SDK authentication information to the server, so that the server authenticates the target external device based on the SDK authentication information to obtain the authentication result of the target external device; if the authentication result returned by the server indicates that the authentication is successful, confirm that the target external device is legal, and send the authentication result to the target external device, so that the target external device confirms that it is connected to the vehicle when confirming that the received authentication result is successful, thereby realizing the use of a standardized authentication process for the target external device, so that the target external device can quickly connect to the vehicle under legal and safe conditions without complicated configuration and debugging; if the first device signal sent by the target external device after confirming that it is connected to the vehicle is received, the first device signal is converted into a first service according to the preset correspondence between the device signal of the target external device and the service, and the first service is published, thereby ensuring the real-time and availability of the service, and the published first service can be directly called by the vehicle-mounted terminal of the vehicle or the terminal associated with the vehicle, that is, by adopting the above-mentioned method, the target external device can be used after connecting to the vehicle, thereby greatly improving the user's experience of using the target external device.

[0065] In one possible implementation, before executing the above step S110, the method further includes:

[0066] Step S210: The server receives an SDK application request for a target external device.

[0067] The SDK application request carries the device parameters of the target external device.

[0068] The application request of the target external device SDK application request may be sent by a developer to the server through a development client.

[0069] The device parameters may include but are not limited to the device type, device model, device manufacturer, device serial number, etc. of the target external device, and are used to provide the necessary information for the server to generate a suitable authentication SDK to ensure that the generated SDK can meet the specific requirements of the device.

[0070] Step S220: the server generates an authentication SDK in response to the SDK application request.

[0071] The server can parse the device parameters in the SDK application request and extract information such as device type, device model, device manufacturer, etc. The server can generate a personalized authentication SDK based on the device parameters to ensure that the generated authentication SDK can meet the needs of specific devices.

[0072] Step S230: The server sends the authentication SDK to the target external device, so that the target external device generates the SDK authentication information based on the authentication SDK.

[0073] The server may send the generated authentication SDK to the target external device through a communication protocol.

[0074] By adopting the above steps S210-S230, since the authentication SDK usually contains multiple modules, such as device ID, specific algorithm module, initial key, etc., the above modules have been tested and optimized and can be used directly by developers. Subsequent developers do not need to write complex authentication logic and algorithms, but only need to call the authentication SDK to generate SDK authentication information, thereby reducing repetitive development work and reducing the workload of developers.

[0075] In one possible implementation, the method further includes:

[0076] Step S240: The server obtains signal details of multiple initial signals of the target external device and the service type corresponding to each initial signal.

[0077] The above step S240 may be to obtain the signal details and service type built into the firmware uploaded by the target external device.

[0078] In another possible implementation, the above step S240 may include steps ac.

[0079] Step a: The server sends a signal to the target external device to fill in the interface.

[0080] The above-mentioned signal interface can be a signal filling interface, which is used to indicate that the target user (such as a developer) needs to fill in the signal details of the various initial signals of the target external device and the service type corresponding to each initial signal on the signal filling interface. The signal details may include: signal sending type (such as periodic sending or sending at a specified time), signal sending period (if the signal sending type is periodic sending, specify the sending period), signal name, signal description (a brief description of the signal), start position (the start position of the initial signal in the message), signal length, signal minimum and maximum values, signal unit, and signal group description. The service type corresponding to the signal can be obtainable (Getter), settable (Setter), notifiable (Notifier), etc.

[0081] Step b: The external device receives the signal details of the multiple initial signals of the target external device and the service type corresponding to each initial signal filled in by the target user through the signal filling interface.

[0082] Specifically, the target user fills in the signal details information of multiple initial signals of the target external device on the signal filling interface and selects or fills in the service type corresponding to each initial signal.

[0083] After the target user completes filling in the form, the target external device saves the filled in information, and in response to a page submission instruction triggered by the target user, feeds back a filling in signal interface indicating the completion of filling in to the server.

[0084] Step c: The server obtains the completed signal filling interface to obtain the signal details of the multiple initial signals of the target external device in the signal filling interface and the service type corresponding to each initial signal.

[0085] Among them, the server can parse the completed signal filling interface and extract the signal details and service type of each initial signal.

[0086] Step S250: The server generates a device signal corresponding to each initial signal based on the signal details of each initial signal of the target device and the corresponding service type.

[0087] In one possible implementation, the device signal identifier of the target device may be obtained, and the device signal identifier may be concatenated with the signal details and service type in each initial signal to obtain the device signal.

[0088] In another possible implementation, the above step S250 includes the server executing the following steps d-f.

[0089] Step d: Obtain the device signal identifier of the target external device.

[0090] The above-mentioned device signal identifier may be composed of one or more of numbers, letters or symbols, etc., and is used to identify that the signal sent by the target external device is sent by the target external device.

[0091] In one possible implementation, the device signal identifier of the target external device may be generated based on signal details of multiple initial signals and the service type corresponding to each signal.

[0092] In another possible implementation, the device signal identifier of the target external device may also be generated by a random number generator, each device signal identifier is within a specified range, such as between 0x600-0x6FF, and the device signal identifiers of different external devices may be different.

[0093] The device signal identifier may specifically be a CAN ID, which is used to determine the priority of a data frame carrying the CAN ID. The smaller the value of the CAN ID, the higher the priority of the corresponding data frame. If the main controller receives data frames sent by different external devices at the same time, the CAN ID in one data frame is 0x100, and the CAN ID in another data frame is 0x101. Since the priority of 0x100 is higher than 0x101, the data frame with the CAN ID of 0x100 will be processed first.

[0094] Step e: Generate a signal representation value of the initial signal based on the signal length and signal value of the initial signal and the service type corresponding to the initial signal.

[0095] The signal indication value can be obtained by concatenating the signal length and signal value of the initial signal and the parameter value of the service type corresponding to the initial signal. In one embodiment, the signal indication value can be specifically represented as a TLV value, where different service types can correspond to different parameter values. For example, the range of T is 4 bits, the range of L is 4 bits, and the value of V is specifically defined according to the initial signal. Then the TLV value can be represented by the following table:

[0096]

[0097]

[0098] Step f: concatenate the device signal identifier and the signal representation value and signal details of the initial signal to obtain a device signal corresponding to the initial signal.

[0099] The order of splicing the device signal identifier, signal representation value and signal details can be arbitrary.

[0100] Since the device signal identifiers (such as CAN ID) corresponding to different external devices are unique, the definition of the signal representation value can be automatically converted into a message (such as automatically converted into a Setter) through the above table for the initial signal, the device signal identifier and the signal representation value. The TLV definition is actually converted into a specific numerical value, and the corresponding service can be obtained according to the specific numerical value. For example, the binary of TLV is 0000 0000 01 01, 0000 represents Setter, 000001 represents a length of 2 bits, and 01 represents the definition value of the signal (assuming 01 represents the window is open, 00 represents the window is closed, and the value is 01 at this time, which means the window is open).

[0101] By adopting the above steps S251-S253, it is possible to splice the signal identification, signal representation value and signal details into a complete device signal, ensure the integrity and consistency of the device signal, ensure that each device signal has a unique identifier, avoid signal conflicts, and in addition, the generated device signal has a clear structure, which is convenient for developers and system administrators to manage and maintain.

[0102] Step S260: The server sends the device signal to the target external device.

[0103] Specifically, the server can organize the generated device signal into a format suitable for transmission, such as a data packet in the form of CAN, TCP / IP, MQTT, etc., and send it to the target external device through a corresponding protocol. For example, if the target device communicates via a CAN bus, the server can organize the device signal into a CAN data packet and send the CAN data packet to the target external device using the CAN protocol.

[0104] Step S270: The server establishes a preset correspondence between the device signal of the target external device and the service based on the device signal corresponding to each of the initial signals and the service type corresponding to each of the initial signals.

[0105] Step S280: The server sends the preset corresponding relationship to the main controller.

[0106] Among them, by establishing a preset correspondence between device signals and services, the preset correspondence between device signals and services can be subsequently stored in a database or configuration file, and the preset correspondence can be sent to the main controller to perform the aforementioned steps S110-S150, so as to ensure that the device signal can be correctly mapped to the corresponding service type, so that the device can convert the signal into a service according to the preset correspondence.
