Description

Technical Field

[0001] This application relates to the field of remote upgrade technology for intelligent vehicles, specifically to a method, apparatus, equipment, and medium for remote upgrade of production line vehicles. Background Technology

[0002] With the rapid development of vehicle networking technology, the upgrade of vehicle software systems is no longer limited to physical vehicle operation and manual flashing. The demand for remote upgrades and various application scenarios for remote upgrades have emerged.

[0003] Currently, the use cases for remote vehicle software upgrades are mostly after a car has been sold. Due to system optimization, function addition, problem fixing, user needs, etc., it is necessary to perform batch remote upgrades or specific vehicle remote upgrades, as well as scheduled upgrades, so that users can upgrade the vehicle system anytime, anywhere, more conveniently and quickly.

[0004] Existing technologies propose using the vehicle's SIM card's mobile network traffic to download and update software upgrade packages for some of the vehicle's controller systems after the vehicle and user have completed real-name authentication. However, for vehicles still on the production line, since the vehicle and user have not yet completed real-name authentication, the SIM card's mobile network traffic is limited and its usage is restricted. Furthermore, the production line has a large number of vehicles, and each vehicle needs to download and update software packages for all controllers, as well as temporarily perform large-scale updates for some controller systems.

[0005] Existing technologies propose a self-organizing network flashing method, which first transmits the flashing data packet quickly and accurately to a specific vehicle, and then achieves the purpose of transmitting the software package between vehicles through vehicle-shared access. However, for vehicles on the production line, it is currently not possible to use mobile networks to achieve remote direct connection upgrades for all vehicles. Summary of the Invention

[0048] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0050] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0051] Please refer to the following first. Figure 1 , Figure 1 This is a schematic diagram illustrating the implementation environment of a remote upgrade method for production line vehicles, as shown in an exemplary embodiment of this application. The implementation environment includes a terminal 101, a cloud server 102, and a factory server 103. The cloud server 102 and factory server 103 are used to execute the remote upgrade method for production line vehicles in this embodiment, and the terminal 101 is used to obtain the upgrade software package and upgrade the controller.

[0052] in, Figure 1 The terminal 101 shown may be, for example, a vehicle-mounted terminal. Figure 1The cloud server 102 and factory server 103 shown can be, for example, independent physical servers, server clusters or distributed systems composed of multiple physical servers, or cloud servers providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. No restrictions are placed on these aspects. Terminal 101 can communicate with the cloud server 102 via 3G (third-generation mobile information technology), 4G (fourth-generation mobile information technology), and with the factory server 103 via 5G (fifth-generation mobile information technology). No restrictions are placed on this aspect either.

[0053] Figure 2 This is a flowchart illustrating a remote upgrade method for production line vehicles, as shown in an exemplary embodiment of this application. The method provided in this application embodiment can be executed by any electronic device with computing power; for example, the method can be executed by the aforementioned... Figure 1 The cloud server 102 and factory server 103 in the embodiments are used as examples to illustrate the execution subjects, but this disclosure is not limited to this.

[0054] Reference Figure 2 The remote upgrade method for production line vehicles provided in this application includes at least the following steps S210 to S240.

[0055] In step S210, the location information of at least one vehicle on the automobile production line is obtained through a pre-built mobile network channel.

[0056] For example, there are two network channels between the vehicle and the factory server. One is a remote upgrade command distribution channel, where the factory server uses a cloud server as an intermediary and leverages the mobile network of a regular base station to establish a long-term connection with the vehicle, using minimal bandwidth. The other is a software package download network channel, where the vehicle uses a dedicated 5G network established by the factory base station to access the factory server and a specific network domain to download updated ECU software packages. This dedicated 5G network is used exclusively for software package downloads within the factory premises and offers high bandwidth. Furthermore, after the vehicle leaves the factory (including after sale), the long-term connection between the vehicle and the cloud server can still be used for vehicle-to-cloud remote communication during normal operation; however, the dedicated 5G network between the vehicle and the factory server will be unavailable, remaining limited to the factory premises.

[0057] In step S220, if the location information of at least one vehicle matches the preset upgrade station location information, an upgrade command is sent to the vehicle terminal.

[0058] For example, the upgrade instruction includes the download address of the upgrade package, controller wake-up parameters, and information about the controller to be upgraded.

[0059] In step S230, the vehicle terminal receives the upgrade package download request uploaded in response to the upgrade command.

[0060] For example, after responding to the upgrade command, the vehicle terminal obtains the software package download address from the upgrade command and uploads the upgrade software package download request to the factory server.

[0061] In step S240, in response to the upgrade package download request, the package indicated by the upgrade package download address is sent to the vehicle terminal through a pre-built package download network channel to upgrade the software of the controller to be upgraded.

[0062] Through the steps S210 to S240 above, after the vehicle arrives at the designated workstation, the factory server sends a remote upgrade command to the vehicle terminal through the cloud server; the vehicle terminal accesses the factory server through the 5G private network, and then downloads the software package to its local machine according to the software package download address carried in the command, and distributes it to each controller to be upgraded.

[0063] In one embodiment of this application, for Figure 2 The vehicle information binding steps preceding step S210 in the illustrated embodiment are described in detail. See [link / reference] Figure 3 , Figure 3 yes Figure 2 The vehicle information binding steps preceding step S210 in the illustrated embodiment are shown in detail in a flowchart of an exemplary embodiment below:

[0064] S310. Obtain the vehicle identification number, on-board terminal hardware information and certificate key of at least one vehicle;

[0065] S320: Bind the vehicle identification code with the hardware information and certificate key of the vehicle terminal to remotely manage at least one vehicle.

[0066] To accurately send commands to vehicles via the cloud server, the hardware part number, certificate key, and other information from the 5G module's hardware information module need to be registered on the cloud server and bound to the vehicle's VIN code, thereby enabling remote control of all vehicles. Simultaneously, the cloud server synchronizes relevant vehicle information to the factory server.

[0067] In one embodiment of this application, before obtaining the location information of at least one vehicle on the automobile production line through a pre-built mobile network channel, the method further includes:

[0068] Send a wake-up command to the vehicle terminal to wake up the vehicle terminal;

[0069] Establish a connection with the mobile network module in the vehicle terminal, and construct a mobile network channel between the vehicle terminal and the vehicle terminal based on the MQTT protocol;

[0070] A connection is established with the 5G network module in the vehicle terminal to construct the software package download network channel, and a network access token is issued to the vehicle terminal. The software package download network channel is used to enable the vehicle terminal to access the upgrade software package download address through the network access token and the HTTPS protocol.

[0071] In one embodiment of this application, the upgrade command further includes controller wake-up parameters and controller information to be upgraded. After the upgrade command is sent to the vehicle terminal, the following steps are also included:

[0072] The vehicle-mounted terminal determines the controller in the vehicle to be upgraded based on the controller information to be upgraded.

[0073] The controllers in the vehicle or the controller to be upgraded are woken up according to the controller wake-up parameters.

[0074] In one embodiment of this application, the step of sending the software package indicated by the upgrade software package download address to the vehicle terminal through a pre-built software package download network channel includes:

[0075] If the location information of at least one vehicle matches the preset vehicle software package download station location, the software package of the vehicle controller indicated by the upgrade software package download address is sent to the vehicle terminal through a pre-built software package download network channel.

[0076] In this embodiment, remote vehicle upgrades on the factory production line are performed uniformly at fixed workstations. The software package for all ECUs of the entire vehicle can be downloaded at one workstation at a time, or the software package for a specific ECU can be downloaded at a specific workstation based on workstation assignment. Therefore, remote vehicle upgrades require downloading the corresponding software package based on the vehicle's current workstation location information.

[0077] In one embodiment of this application, the software upgrade of the controller to be upgraded includes:

[0078] If the software package is an in-vehicle terminal upgrade software package, then the in-vehicle terminal is upgraded according to the in-vehicle terminal upgrade software package;

[0079] If the software package is not an in-vehicle terminal upgrade software package, then the software of other controllers in the vehicle to be upgraded is upgraded according to the software package.

[0080] In this embodiment, if it is a software upgrade package for the vehicle system itself, it is executed by its own ECU upgrade module; if it is a software upgrade package for other ECUs in the vehicle, it is transmitted by the upgrade package processing module to the communication module with other controllers in the vehicle, and distributed to other ECUs in the vehicle through the Ethernet channel, where each ECU performs the software upgrade.

[0081] In one embodiment of this application, see Figure 4 , Figure 4 This is a flowchart illustrating another exemplary embodiment of the present application of a method for remotely upgrading production line vehicles. The method for remotely upgrading production line vehicles in this embodiment will be described in detail below:

[0082] S410, Vehicle Binding: To accurately send commands to vehicles via the cloud server, the hardware part number, certificate key, and other information from the 5G module's hardware information module need to be registered on the cloud server and bound to the vehicle's VIN code and other information, thereby enabling remote control of all vehicles. Simultaneously, the cloud server synchronizes relevant vehicle information to the factory server.

[0083] S420, Vehicle Connectivity: Establishes a network between the vehicle's infotainment system and the factory server. If the vehicle's infotainment system is in a dormant state, the cloud server needs to send an SMS message to the vehicle's 5G module via the operator to wake up the system.

[0084] S421, Multi-channel dial-up internet access: After the vehicle's infotainment system is installed and powered on, the network module establishes one network channel with the cloud server and the factory server respectively, corresponding to data dial-up APN1 and APN2. APN1 uses the mobile network of ordinary base stations outside the factory, which does not restrict access to domain names, but the traffic is extremely low, so it currently only connects to the cloud server; APN2 uses the 5G private network within the factory, which is limited to accessing the specified domain names configured in the network module, to prevent the 5G private network from being used for other purposes.

[0085] S422. Establish MQTT long connection channel: The remote command receiving / sending module establishes a long connection channel between the vehicle system and the cloud server based on the MQTT protocol, supporting the factory server to send remote upgrade commands in real time.

[0086] S423. Establish a remote software package download channel: After the network module connects to the factory server, it obtains a network access token. The vehicle's infotainment system can then use this token to directly access the software package download address via HTTPS and receive software packages from the ECU.

[0087] S430, Remote Software Upgrade: The factory server remotely upgrades the vehicle software.

[0088] S431. Identify vehicle location information: The GPS module of the 5G module reports the vehicle location information to the cloud server at a time interval of 1 second, and then the cloud server forwards it to the factory server.

[0089] S432. Remote Upgrade Command Issuance: The factory server determines the vehicle's location based on its location information and sends a remote upgrade command via the cloud server to the vehicle's remote command receiving / sending module. The command includes not only the ECU to be upgraded but also the download address of the corresponding software package. The remote command receiving / sending module transmits the wake-up parameters to the power management module, which then sends them to the CAN channel via communication modules with other vehicle controllers, directly waking up the entire vehicle or partially waking up the ECU to be upgraded.

[0090] S433, Download and Distribute Software Upgrade Package: The remote command receiving / sending module transmits the software package download address in the command to the upgrade package receiving data module. This module directly accesses the address, downloads the software package to its local machine, and then transmits it to the upgrade package management module. If it is a software upgrade package for the vehicle's own infotainment system, it is executed by its own ECU upgrade module; if it is a software upgrade package for other ECUs in the vehicle, it is transmitted by the upgrade package processing module to the communication module with other controllers in the vehicle, and distributed to other ECUs in the vehicle via the Ethernet channel, where each ECU performs the software upgrade.

[0091] In this embodiment, the vehicle infotainment system is the vehicle terminal; the factory server uses a cloud server as a relay station to send remote upgrade commands to the vehicle, and uses the 5G private network covering the factory to manage and distribute software upgrade packages for each ECU of the vehicle; cloud server 2 is used to establish a communication connection with the vehicle and send remote upgrade commands to the vehicle; the cloud server is used to establish a communication connection with the vehicle terminal and send remote upgrade commands to the vehicle terminal; the vehicle infotainment system equipped with a built-in 5G module can not only provide network access to the vehicle, locate the vehicle's position, and wake up the vehicle's ECUs through the 5G module, but also download, manage, and distribute the vehicle's ECU software packages through other modules of the vehicle infotainment system.

[0092] For example, 5G module 4 needs to include the following functional modules: a remote command receiving / sending module, built using an MQTT channel; a networking module with two network channels; a GPS module; a power management module; and a hardware information module.

[0093] For example, in addition to the 5G module 4, the vehicle system 3 also needs to include the following functional modules: a module for receiving upgrade package data; an upgrade package processing module, which is divided into an upgrade package processing module and its own ECU upgrade module; and a communication module with other controllers in the vehicle.

[0094] Using the method described in the above embodiments, after the vehicle's infotainment system is installed and powered on, the infotainment system establishes a long-term connection with the cloud server and periodically reports the vehicle's location information to the cloud server, which then forwards it to the factory server. Once the vehicle arrives at the designated workstation, the factory server issues a remote upgrade command through the cloud server, which in turn activates the infotainment system to wake up the entire vehicle or a specific ECU. The infotainment system accesses the factory server via a 5G private network, and then, according to the software package download address carried in the command, downloads the software package for the entire vehicle or the specific ECU to its local machine and distributes it to each ECU.

[0095] It should be noted that although the steps of the method in this application are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.

[0096] The following describes an embodiment of the apparatus described in this application, which can be used to execute the remote upgrade method for production line vehicles in the above embodiments of this application. See also Figure 5 , Figure 5 This is a block diagram illustrating a remote upgrade device for production line vehicles, as shown in an exemplary embodiment of this application. The remote upgrade device includes a location information acquisition module 501, an upgrade command issuance module 502, a download request acquisition module 503, and a software package issuance module 504.

[0097] The location information acquisition module 501 is used to acquire the location information of at least one vehicle on the automobile production line through a pre-built mobile network channel.

[0098] The upgrade instruction issuing module 502 is used to issue an upgrade instruction to the vehicle terminal if the location information of the at least one vehicle matches the preset upgrade workstation location information. The upgrade instruction includes the download address of the upgrade software package.

[0099] The download request acquisition module 503 is used to acquire the upgrade package download request uploaded by the vehicle terminal in response to the upgrade instruction;

[0100] The software package distribution module 504 is used to respond to the upgrade software package download request by distributing the software package indicated by the upgrade software package download address to the vehicle terminal through a pre-built software package download network channel for software upgrade of the controller to be upgraded.

[0101] It should be noted that the apparatus provided in the above embodiments and the method provided in the above embodiments belong to the same concept, and the specific way in which each module and unit performs operations has been described in detail in the method embodiments, and will not be repeated here.

[0102] In one embodiment of this application, a remote upgrade system for production line vehicles is also described. See [link to relevant documentation].

[0104] Cloud server 2: Used to establish a communication connection with the vehicle and send remote upgrade commands to the vehicle;

[0105] Vehicle Infotainment System 3: The vehicle-side is equipped with a built-in 5G module 4. The vehicle-side can not only provide network access, locate the vehicle's position, and wake up the vehicle's ECU through the 5G module 4, but also download, manage, and distribute the vehicle's ECU software packages through other modules of the vehicle-side infotainment system 3.

[0106] The 5G module 4 needs to include the following functional modules: a remote command receiving / sending module; a networking module with two networks, APN1 and APN2; a GPS module; a power management module; and a hardware information module.

[0107] In addition to the 5G module 4, the vehicle infotainment system 3 also needs to include the following functional modules: a module for receiving upgrade package data; an upgrade package processing module, which is divided into an upgrade package processing module and its own ECU upgrade module; and a module for communicating with other controllers in the vehicle.
