[0032] Example 1

[0033] The method embodiment provided in Embodiment 1 of this application can be executed on a mobile phone, computer, tablet, or similar computing device. Taking running on a computer as an example, Figure 1 This is a hardware structure block diagram of a computer according to an embodiment of the present invention. For example... Figure 1 As shown, a computer may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. Optionally, the computer may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the computer described above. For example, the computer may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0034] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the access control method for an in-vehicle device in this embodiment of the application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory.

Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0035] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a computer's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0036] This embodiment provides an access control system for in-vehicle devices. The access control method for in-vehicle devices in this embodiment is based on an access control system for in-vehicle devices accessing an intelligent vehicle system, and refers to... Figure 1 The vehicle-mounted device access control system includes the vehicle terminal, the vehicle-mounted devices, and the cloud. The vehicle terminal includes Device Manager 6, Device Management Service 7, and Vehicle General Service 8. Vehicle General Service 8 communicates with Device Management Service 7 via API interface, and Device Manager 6 communicates with Device Management Service 7 via AIDI. The cloud includes Filing System 1, Micro-application Management System 2, and Smart Device Management System 3. The vehicle-mounted devices are specifically wireless smart devices, including Bluetooth devices 4 and WiFi devices 5, such as wireless vehicle-mounted devices like car refrigerators, microphones, and car seats. The vehicle terminal and the vehicle-mounted devices are wirelessly connected, and the Device Management Service communicates with the Smart Device Management System via MQTT.

[0037] The Device Manager service runs on the in-vehicle infotainment system and is a persistent system service. It manages the access and communication with in-vehicle devices and establishes MQTT communication with the intelligent device management system. After detecting an in-vehicle device connection, the Device Manager service sends the device information to the Device Manager app. The Device Manager app retrieves the corresponding micro-application for that in-vehicle device from the micro-application management system, downloads and loads the corresponding micro-application, and then displays the functional interface for that in-vehicle device.

[0038] The intelligent device management system is used to manage the list and classification of intelligent devices, and at the same time, it receives the operating data of the vehicle-mounted devices uploaded by the device management service, and can display the online status and operating status of the vehicle-mounted devices in real time; the registration system is used to provide registration and certification of vehicle-mounted devices to ensure that the connected vehicle-mounted devices are certified by the manufacturer, rather than just any device being able to be connected to the vehicle system.

[0039] The vehicle infotainment general service is used to abstract the capabilities of the entire vehicle and provide a general service interface for other applications to call, such as air conditioning control and seat adjustment capabilities. In this system, all connected vehicle devices call the vehicle infotainment general service through the device manager to control the vehicle. At the same time, the types of connected devices are different, so a standard communication protocol needs to be defined to constrain the communication between the device manager and the wireless devices to achieve compatibility with each device.

[0040] Manufacturers register wireless smart devices in the filing system; they develop corresponding interfaces and functions for in-vehicle devices, package them into micro-applications, and upload them to the micro-application management backend. They configure the specific vehicle models associated with the micro-applications, set the download type and upgrade method, facilitating vehicle-side maintenance and upgrades by retrieving the corresponding vehicle model, upgrade strategy, and upgrade information from the cloud. In the device management system backend, they create device categories, tags, and information, along with their association with vehicle models, and associate the devices with their corresponding micro-applications. First, a connection is established between the in-vehicle device and the device manager service. After connection, the in-vehicle device reports its UUID, and the device manager service verifies its legitimacy with the filing system. If authentication fails, the connection is disconnected; if authentication is successful, the connected in-vehicle device information is transmitted to the device manager app. The device manager app retrieves and downloads the device micro-application from the micro-application management system, loads and renders it, and then displays the in-vehicle device's UI. The device management service communicates with the device management system via MQTT, and wireless device information is uploaded to the cloud through the device management service. Interaction between the wireless device and the in-vehicle device is handled by the device management service calling a general service interface.

[0041] This embodiment provides a method for controlling the access of vehicle-mounted devices. Figure 2 This is a flowchart of an access control method for an in-vehicle device according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0042] Step S10: Obtain the access request from the vehicle-mounted device;

[0043] Step S20: Based on the access request, establish a wireless connection between the vehicle-mounted device and the device management service on the vehicle side;

[0044] Step S30: Load the control component corresponding to the vehicle-mounted device onto the vehicle end;

[0045] Step S40: Control the vehicle-mounted equipment through the control component.

[0046] In this embodiment, the control component can be a micro-application. Developers can develop micro-applications corresponding to the in-vehicle devices based on the characteristics of the in-vehicle devices and product design requirements, and upload them to the cloud-based micro-application management system. The corresponding in-vehicle devices can be controlled through the control component, such as controlling the height of the in-vehicle seats.

[0047] Through the above steps, an access request from the vehicle-mounted device is obtained; based on the access request, a wireless connection is established between the vehicle-mounted device and the device management service on the vehicle side; the corresponding control component for the vehicle-mounted device is loaded on the vehicle side; the vehicle-mounted device is controlled through the control component, and a wireless connection is established between the device management service on the vehicle side and the vehicle-mounted device, thereby realizing flexible access of the vehicle-mounted device.

[0048] Reference Figure 4 The intelligent vehicle device initiates a connection to the device management service and sends its device ID. The device management service queries the list of registered devices from the registration system to determine whether the current vehicle device is on the list, thereby verifying the device's legality. The registration system returns the verification result. If the current vehicle device is a legal device, the device management service notifies the device manager APP that a new device has been connected. The device manager APP obtains the device micro-application corresponding to the device from the micro-application management system. The micro-application management system returns the micro-application information. The device manager APP downloads and loads the micro-application.

[0049] In this embodiment, establishing a wireless connection between the in-vehicle device and the vehicle-side device management service according to the access request includes:

[0050] S21, parse the device type of the vehicle-mounted device according to the access request;

[0051] S22, Based on the device type, establish a wireless connection between the vehicle-mounted device and the device management service on the vehicle side.

[0052] The types of in-vehicle devices include Bluetooth devices and WiFi devices. Since different device types have different connection methods, this embodiment can parse the device type of the in-vehicle device according to the access request sent by the in-vehicle device, and then establish a wireless connection between the in-vehicle device and the device management service on the vehicle side according to the device type.

[0053] In one embodiment of this example, establishing a wireless connection between the in-vehicle device and the vehicle-side device management service, based on the device type, includes:

[0054] S221, if the device type is a WiFi device, then the service set identifier (SSID) and password of the vehicle WiFi are sent to the vehicle-mounted device;

[0055] S222, Receive connection confirmation information sent by the vehicle-mounted device;

[0056] S223, Based on the connection confirmation information, establish a wireless connection between the vehicle-mounted device and the device management service on the vehicle side.

[0057] If the in-vehicle device is a WiFi device, it needs to connect to the vehicle's hotspot. Currently, many in-vehicle devices lack a user interface, such as a WiFi configuration interface on a mobile phone or PC. Therefore, in this embodiment, the SSID and password of the vehicle's WiFi are obtained through network configuration. After connecting to the vehicle's network, communication with the device manager can be achieved via socket. Preferably, this embodiment uses AP network configuration. (See reference...) Figure 5 The diagram shown illustrates the AP network configuration process. The WiFi device is set to AP network configuration mode. The vehicle's infotainment system connects to the WiFi device's AP hotspot to form a local area network. The vehicle's infotainment system sends the vehicle's WiFi service set identifier (SSID) and password to the WiFi device. After receiving the vehicle's WiFi SSID and password, the WiFi device connects to the vehicle's hotspot, thereby establishing a connection between the vehicle's onboard equipment and the vehicle's device management service.

[0058] In another embodiment of this example, establishing a wireless connection between the in-vehicle device and the vehicle-side device management service according to the device type includes: if the device type is a Bluetooth device, obtaining a Bluetooth connection request from the in-vehicle device; and establishing a wireless connection between the in-vehicle device and the vehicle-side device management service based on the Bluetooth connection request.

[0059] If the device type of the in-vehicle device is a Bluetooth device, then obtain the Bluetooth connection request of the in-vehicle device, and perform Bluetooth scanning, pairing, and connection steps based on the Bluetooth connection request to establish a wireless connection between the in-vehicle device and the management service of the vehicle-side device.

[0060] In one embodiment of this example, after establishing a wireless connection between the in-vehicle device and the vehicle-side device management service according to the access request, the method further includes:

[0061] S51, Receive the device ID reported by the vehicle-mounted device;

[0062] S52, retrieve the device part number corresponding to the device ID from the cloud-based filing system;

[0063] S53, if a device part number corresponding to the device ID exists, then the control component corresponding to the vehicle device is loaded through the device manager on the vehicle side;

[0064] S54, if there is no device part number corresponding to the device ID, then disconnect the wireless connection between the vehicle-mounted device and the device management service on the vehicle side.

[0065] After establishing a wireless connection between the in-vehicle device and the vehicle-side device management service, the in-vehicle device needs to proactively report its device ID according to the protocol. This allows the device management service to perform legitimate authentication of the connected in-vehicle device based on the device ID, preventing unauthenticated devices from potentially damaging system performance. Specifically, the device management service receives the device ID reported by the in-vehicle device and searches for the corresponding device part number in the cloud-based registration system. If a device part number exists, it means the in-vehicle device has been registered in the registration system and passes legitimate authentication. After successful authentication, the device management service notifies the device manager of the device access information. The device manager app displays the access information of the newly connected in-vehicle device and simultaneously retrieves and downloads the corresponding micro-application from the cloud-based micro-application management backend. After loading and rendering, the device manager displays the UI interface of the in-vehicle device. If a device part number does not exist, it means the in-vehicle device has not been registered in the registration system and fails legitimate authentication. In this case, the wireless connection between the in-vehicle device and the vehicle-side device management service is disconnected.

[0066] For example, before the vehicle-mounted device is connected, a standard access communication protocol is established for the vehicle-mounted system, and the corresponding software for the vehicle-mounted device is developed in accordance with the standard access communication protocol. The vehicle-mounted device is registered in the cloud-based registration system. The registration information includes the device supplier, device type, and device part number. The device part number is associated with the device ID of the vehicle-mounted device, which facilitates the legal authentication of the vehicle-mounted device based on the registration information when the vehicle-mounted device is connected.

[0067] The cloud-based intelligent device management system creates corresponding device categories, device tags, device information, and associated vehicle models. It also obtains the micro-applications corresponding to the in-vehicle devices, uploads the micro-applications to the cloud-based micro-application management system, and associates the in-vehicle devices with their corresponding micro-applications, so that the corresponding device's micro-applications can be obtained when the device is connected.

[0068] In another embodiment of this example, after establishing a wireless connection between the in-vehicle device and the vehicle-side device management service according to the access request, the method further includes:

[0069] A receives a first control command sent from the cloud, the first control command being used to remotely control the vehicle-mounted equipment;

[0070] B forwards the first control command to the vehicle-mounted device;

[0071] C obtains the execution status of the vehicle-mounted device executing the first control command and uploads the execution status to the cloud.

[0072] refer to Figure 6 The diagram illustrates the process of remotely controlling an in-vehicle device. In one implementation scenario, a user can remotely control the power switch of the in-vehicle device from home. First, the device management service on the vehicle receives a first control command from the cloud. This command is used to remotely control the in-vehicle device. The device management service forwards the command to the in-vehicle device, which executes the command and uploads its execution status to the device management service. The device management service then uploads the execution status to the cloud. The cloud parses the execution status and displays it on the user's device. The cloud-based intelligent device management system and the device management service are connected via MQTT communication, while the in-vehicle device and the device management service are wirelessly connected.

[0073] In this embodiment, the vehicle-side device can upload device information and operational status information of the on-board equipment to the cloud via MQTT, facilitating real-time acquisition of the operational status of the connected on-board equipment in the cloud. Simultaneously, the cloud can issue control commands to the on-board equipment. The cloud sends these control commands to the device management service on the vehicle-side via MQTT, and the device management service transmits the control commands to the on-board equipment via wireless communication. The on-board equipment then executes the control commands, thereby completing remote control of the on-board equipment. The transmission of both control commands and device information conforms to standard communication protocols.

[0074] In another embodiment of this example, after establishing a wireless connection between the vehicle-mounted device and the device management service on the vehicle terminal according to the access request, the method further includes: receiving a second control request sent by the vehicle-mounted device, the second control request being used to request control of the vehicle terminal or to obtain the operating status of the vehicle terminal; and invoking a general service interface to control the vehicle terminal or to obtain the operating status of the vehicle terminal.

[0075] The system receives a second control request from the in-vehicle device. This request is used to request control of the vehicle or to obtain the vehicle's operating status. Control of the vehicle or acquisition of its operating status is achieved by calling a general service interface. The in-vehicle system abstracts the capabilities of the entire vehicle, providing a general service interface for the whole vehicle. The device management service calls these general services to complete the interaction between the in-vehicle device and the in-vehicle system. After the intelligent vehicle is connected, it creates a complete and consistent user experience between the intelligent device and the entire vehicle.

[0076] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.
