Referring to fig. 1, fig. 1 is a schematic diagram illustrating an implementation environment of a vehicle OTA upgrading method according to an exemplary embodiment of the present application.
As shown in fig. 1, the implementation environment may include a TSP server 110 and a smart car 120, wherein a master node 121 and a controller 122 are configured in the smart car 120. The master node 121 may include any one of a T-BOX or a car machine, etc., the number of controllers 122 is greater than or equal to 1, and the controllers 122 include target controllers. The TSP server 110 may be implemented by a separate server or a server cluster formed by a plurality of servers, where the TSP server 110 provides an OTA upgrade service, including transmitting an upgrade packet and guiding installation and upgrade, and the TSP server 110 issues an OTA upgrade instruction to the master node 121, so that the master node 121 establishes an information channel between the TSP server and the target controller, and the OTA upgrade of the target controller is completed through the information channel.
Illustratively, the main node 121 is used as a wireless access node of the star flash wireless local area network, after receiving an OTA upgrade instruction issued by the TSP server 110, the main node 121 obtains target identification information of the target controller based on the OTA upgrade instruction, performs identity authentication according to the target identification information, determines the target controller from the controllers 122, establishes an information channel between the target controller and the TSP server 110, and sends data to be upgraded in the TSP server 110 to the target controller in a segmented manner through the information channel, so that the target controller reorganizes the data to be upgraded to obtain an upgrade packet of the target controller, and upgrades the target controller based on the upgrade packet. Therefore, the technical scheme of the embodiment of the application can realize private network special and network isolation, and can improve the transmission efficiency of the upgrade package, thereby improving the vehicle OTA upgrade efficiency.
It should be noted that, the vehicle OTA upgrading method provided in the embodiment of the present application is generally specifically executed by the TSP server 110, the master node 121, and the controller 122.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for upgrading a vehicle OTA according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1 and specifically performed by TSP server 110, master node 121, and controller 122 in the implementation environment. It should be understood that the method may be applied to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and the implementation environments to which the method is applied are not limited by the present embodiment.
As shown in fig. 2, in an exemplary embodiment, the vehicle OTA upgrading method at least includes steps S210 to S230, which are described in detail as follows:
step S210, the main node receives the OTA upgrade instruction, obtains the target identification information of the target controller based on the OTA upgrade instruction, and the main node is a wireless access node of the star flash wireless local area network.
In one embodiment of the present application, the T-BOX is used as a master node for OTA upgrade and an AP node (Access Point) of a star flash wireless local area network. The TSP server issues an OTA upgrade instruction to the T-BOX through the 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) or 4G (4 th Generation Mobile Communication Technology, fourth generation mobile communication technology) mobile cellular network, where the OTA upgrade instruction includes an ECU identifier (identification information of the target controller) and an upgrade package version number (upgrade package version information of the target controller). After receiving the OTA upgrade instruction issued by the TSP server, the main node analyzes the OTA upgrade instruction once to obtain the target identification information of the target controller.
It should be noted that, the star flash wireless lan is a wireless lan created based on the star flash technology. The star flash technology is a new generation wireless short-distance communication technology and mainly comprises two parts: star flash transmitters and star flash receivers, the principle of the star flash technology is to communicate by transmitting and receiving electronic signals. Compared with the traditional wireless communication technologies such as Bluetooth and WIFI, the star flash technology has the characteristics of low time delay, high reliability, high synchronism, high concurrency and the like, can support synchronous access of 256 users at most, and meets the increasing trend of controllers in vehicles.
In one embodiment of the present application, before the master node receives the OTA upgrade instruction, the vehicle OTA upgrade method includes: an OTA upgrade notification is sent to the terminal, so that the terminal obtains a selection result of a user according to the OTA upgrade notification, wherein the selection result comprises upgrade or non-upgrade, and the terminal comprises a vehicle-mounted terminal or a user terminal; if the selection result is upgrading, sending an OTA upgrading instruction to the main node.
In a specific embodiment of the present application, before the TSP server issues the OTA upgrade instruction, it first interacts with the vehicle cloud platform, and issues an OTA upgrade notification to the terminal through the vehicle cloud platform, after the user obtains the OTA upgrade notification through the terminal, it can autonomously select whether to perform the OTA upgrade, if the user selects to perform the upgrade, the corresponding selection result is upgrade, if the user selects not to perform the upgrade, the corresponding selection result is not upgrade, and the terminal feeds back the selection result of the user to the vehicle cloud platform. And the cloud platform returns different messages to the TSP server according to different selection results, returns a continuous process message to the TSP server if the selection results are upgrading, so that the TSP server issues an OTA upgrading instruction, and returns a process stopping message to the TSP server if the selection results are not upgrading, so that the TSP server stops the subsequent operation process. The terminal may be a vehicle-mounted terminal or a user terminal such as a user's cell phone number, an application on a mobile device, etc.
In one embodiment of the present application, before the master node receives the OTA upgrade instruction, the vehicle OTA upgrade method further includes: a star-flash wireless local area network is constructed based on a star-flash technology, wherein the star-flash wireless local area network comprises a main node and a controller; the master node is used as a wireless access node of the star flash wireless local area network and is used for communicating with the TSP server and the controller.
In this embodiment, before the host node receives the OTA upgrade instruction, a star flash wireless local area network in the vehicle is built based on the star flash technology, and is used as an OTA upgrade private network, where the star flash wireless local area network includes one or more host nodes and one or more controllers, and the host node is used as an AP node of the star flash wireless local area network and is responsible for communication with the TSP server and the ECU, identity authentication connection of the ECU, routing forwarding of an OTA message, access of the ECU node to the 5G cellular network, establishment of a network constant connection (information channel) between the TSP server and the controller, and the like. Because the main node and the target controller of the OTA upgrade are both in the star flash wireless local area network, the transmission data formats are the same, and the OTA upgrade does not occupy the bandwidth of the wired network in the vehicle, so that the transmission speed of the upgrade package can be effectively improved, and the transmission time is shortened.
In one embodiment of the present application, the star flash wireless lan is a star topology, and the master node is a central node of the star topology.
In this implementation, a star-type topology may be used to create a star-flash wlan, where the master node is one and serves as the central node of the star-type topology. For example, the T-BOX may be used as a master node for OTA upgrade, and also as an AP node and a central node of a star topology. Referring to fig. 3, fig. 3 is a star flash wireless lan topology shown in an exemplary embodiment of the present application. As shown in fig. 3, the star flash wireless local area network comprises a T-BOX and a plurality of ECUs, wherein the T-BOX is used as a central node and an AP node of the star flash wireless local area network, and the T-BOX and the ECUs are connected through a star flash technology to form the star flash wireless local area network with a star topology. And taking the T-BOX as a main node of OTA upgrading so that the star flash wireless local area network is taken as an OTA upgrading private network.
Step S220, performing identity authentication according to the target identification information to establish an information channel between the target controller and the TSP server.
In one embodiment of the present application, a master node performs identity authentication according to target identification information and a controller in a star flash wireless local area network, determines whether the identification information of each controller is the same as the target identification information, if the identification information of a controller is the same as the target identification information, it indicates that the identity authentication is passed, the controller that passes the identity authentication is taken as a target controller, and a normal connection network channel (information channel) between the target controller and a TSP server is established by using a wireless network management technology for subsequently transmitting an upgrade package of the target controller. The number of the target controllers can be one or more, different information channels are established between the TSP server and different target controllers, upgrade packages of different target controllers can be transmitted in parallel, and the time for upgrading the whole car OTA is further shortened.
In one embodiment of the present application, performing identity authentication according to target identification information to establish an information channel between a target controller and a TSP server includes: the master node broadcasts an addressing request to a controller in the star-flash wireless local area network based on the target identification information so that the master node and the target controller perform identity authentication once, and if the identity authentication once passes, network connection between the master node and the target controller is established; and carrying out secondary identity authentication on the target controller and the TSP server, and if the secondary identity authentication passes, establishing an information channel, wherein the secondary identity authentication comprises one-way identity authentication or two-way identity authentication.
In this embodiment, the T-BOX generates a connection request message (addressing request) according to the target identification information, and broadcasts the connection request message to the controllers in the star-flash wireless lan through the star-flash technology, so as to find the target controller. Each controller monitors the broadcasted connection request message, identifies the target identification information in the connection request message, performs one-time identity authentication, if the identification information of the controller is the same as the target identification information, the controller sends back a connection approval message to the T-BOX, which indicates that one-time identity authentication passes, and the controller is the target controller correspondingly, and the T-BOX establishes network connection with the target controller through the star flash technology. After the T-BOX establishes network connection with the target controller, the T-BOX returns an OTA upgrading agreement message to the TSP server so as to carry out secondary identity authentication between the target controller and the TSP server, if the secondary identity authentication passes, an information channel is established, and if the secondary identity authentication does not pass, no subsequent operation is carried out. The secondary identity authentication includes one-way identity authentication or two-way identity authentication, i.e., the target controller may verify whether the identification information of the TSP server is correct, or the TSP server may verify whether the identification information of the target controller is correct, or the target controller and the TSP server mutually verify whether the identification information of the other party is correct. The bidirectional identity authentication ensures the security of OTA upgrading, prevents the ECU from being tampered or impersonated maliciously, and further effectively ensures the security of the vehicle-mounted information system.
In one embodiment of the present application, after establishing a network connection between a master node and a target controller, a vehicle OTA upgrade method includes: the master node sends a state query request to the target controller to obtain the state of the target controller; if the target controller is in a leisure state, a version inquiry request is sent to the target controller to obtain the current version information of the target controller; if the current version information is inconsistent with the version information of the upgrade package of the target controller, sending an OTA upgrade request to the TSP server for secondary identity authentication, wherein the version information of the upgrade package is obtained based on the OTA upgrade instruction.
In this embodiment, after establishing a network connection between the T-BOX and the target controller, the T-BOX initiates a query message (a state query request) to the target controller to query the current state of the target controller, if the target controller is in a working state, the subsequent operation is stopped, and if the target controller is in a leisure state, the T-BOX initiates a secondary query message (a version query request) to the target controller to query the current software version number (current version information) of the target controller, and simultaneously performs secondary analysis on the OTA instruction to obtain the software version number (upgrade package version information of the target controller) to be upgraded. And the T-BOX compares the current version information with the version information of the upgrade package, if the current version information is consistent with the version information of the upgrade package, the subsequent operation is stopped, and if the current version information is inconsistent with the version information of the upgrade package, an OTA upgrade request (OTA upgrade approval message) is sent to the TSP server so as to carry out secondary identity authentication.
In another embodiment of the present application, when querying the state and the current software version number of the target controller, the T-BOX may also initiate a query message only once to the target controller, so that the target controller returns the current state and the current software version number to the T-BOX together.
Step S230, the data to be upgraded of the TSP server is sent to the target controller in a segmented mode through the information channel, so that the target controller reorganizes the data to be upgraded, an upgrade package of the target controller is obtained, and the target controller is upgraded.
In one embodiment of the present application, an OTA main control program on a TSP server pre-packetizes an upgrade packet of a target controller to obtain a plurality of data to be upgraded, and the plurality of data to be upgraded are sent to the target controller in a message form in a segmented manner through an information channel. After the target controller receives all the segmented messages (i.e. the data to be upgraded), the segmented messages are recombined to obtain an upgrade package of the target controller. And the target controller performs OTA software package installation and upgrading under the guidance of an OTA main control program.
In one embodiment of the present application, step S230 includes: the TSP server carries out subpackaging and encryption processing on the upgrade package to obtain data to be upgraded; the data to be upgraded are sent to the target controller in a segmented mode through an information channel; the target controller decrypts and reorganizes the data to be upgraded to obtain an upgrade package, and upgrades the upgrade package.
In this embodiment, homomorphic encryption chips and algorithms are embedded in the TSP server and each controller in advance, an OTA main control program of the TSP server encrypts an OTA upgrade package (upgrade package of a target controller) by using homomorphic encryption technology, information security is guaranteed, the OTA upgrade package is subjected to subpackaging processing to obtain a plurality of data to be upgraded, and a 5G cellular network and a star flash technology local area network are utilized to directly send messages of the data to be upgraded to the target controller in a segmented manner through an established information channel, so that transmission efficiency and quality are improved. And the target controller receives the segmented messages, decrypts and stores the segmented messages, and reorganizes the segmented messages after all the segmented messages arrive to obtain an upgrade package. And the target controller performs OTA software package installation and upgrading under the guidance of an OTA main control program.
In one embodiment of the present application, after the OTA upgrade is finished, the target controller returns an OTA upgrade success message to the TSP server, and the TSP server sends a connection interrupt message to the T-BOX, interrupts a normal connection network channel between the TSP server and the controller, and releases resources in real time, thereby avoiding wasting bandwidth resources.
According to the technical scheme, a star flash technology and a star topology structure are adopted to construct a star flash wireless local area network in the vehicle, a T-BOX is used as an OTA main node and an AP node of the star flash wireless local area network, communication between the OTA main node and each controller is realized by using the star flash technology, and meanwhile, the main node is connected to a 5G/4G cellular communication network, so that the special network and the network isolation effect are achieved. When the TSP server issues an OTA upgrading instruction, the master node performs controller addressing and bidirectional identity authentication according to an ECU identity identifier (target identification information of a target controller) in the OTA upgrading instruction, and network transparent transmission is realized between the master node and an upgrading ECU (target controller), so that the TSP server performs OTA control on the whole vehicle ECU. Meanwhile, homomorphic encryption chips and algorithms are embedded in the TSP server and the ECU controller, so that homomorphic encryption of instructions and OTA upgrade packages between the TSP server and the ECU is realized, and information security requirements are met.

2) The vehicle cloud platform returns user selection information (selection result) to the TSP server, if the user selects to upgrade, a continuous process message is returned to the TSP server, and subsequent operation is carried out; if the user selects not to upgrade, returning a process stopping message to the TSP server to stop the subsequent operation process;
3) The TSP server transmits an OTA upgrading instruction to the T-BOX through the 5G/4G mobile cellular network, wherein the OTA upgrading instruction comprises an ECU identifier (used for identifying an ECU needing to be upgraded, namely a target controller, for establishing connection in a subsequent upgrading mode) and an upgrading packet version number;
4) The T-BOX analyzes the OTA upgrading instruction issued by the TSP server and identifies the ECU identifier;
5) The T-BOX broadcasts through a star flash technology according to the ECU identifier, sends a connection request message, and searches for a target controller;
6) Each controller monitors the broadcast message, and the target controller sends back a message of agreeing to connect to the T-BOX;
7) The T-BOX establishes network connection with a target controller based on a star flash technology;
8) The T-BOX initiates an inquiry message to the target controller, and inquires the current state of the target controller and the current software version number of the target controller;
9) The target controller feeds back the current software version number and the current state to the T-BOX;
10 T-BOX) identifies the current state of the target controller, if the target controller is in the working state, the subsequent OTA upgrading operation is not performed, and if the target controller is in the idle state, the subsequent OTA upgrading operation is performed;
11 The T-BOX analyzes the version number of the software to be upgraded in the issued OTA upgrading instruction and compares the version number with the current version number of the software in the return information of the target controller;
12 If the current software version number is consistent with the software version number to be upgraded, stopping subsequent operation, and if the software version is inconsistent, performing subsequent operation;
13 The T-BOX returns an OTA upgrade agreement message to the TSP server, which indicates that the target controller can carry out OTA upgrade;
14 The TSP server transmits an identity authentication request message to the target ECU through T-BOX, performs bidirectional identity authentication with the target ECU, and performs subsequent operation if the bidirectional identity authentication passes;
15 The TSP server sends a bidirectional identity authentication passing message to the T-BOX;
16 The T-BOX establishes a normally connected network channel between the TSP server and the target controller through a wireless network management technology when an OTA software package (upgrade package of the target controller) is transmitted subsequently;
17 The TSP server encrypts the OTA upgrade package by using a homomorphic encryption technology to obtain an OTA encryption software package, so that the information security is ensured;
18 OTA master control program on TSP server, through 5G cellular network, star flash technical LAN, send OTA encryption software package to the goal controller directly;
19 The TSP server performs segmented transmission on the OTA encryption software package, so that the transmission quality is ensured;
20 The target controller receives the segmented messages of the OTA encryption software package, decrypts and stores the segmented messages, and reorganizes the segmented messages after all the segmented messages arrive to obtain the OTA software package;
21 The target controller performs OTA software package installation and upgrading under the guidance of a TSP server main control program;
22 After OTA upgrading is finished, the target controller returns an OTA upgrading success message to the TSP server;
23 The TSP server sends a connection interrupt message to the T-BOX, interrupting the constant connection network channel between the TSP server and the target controller.
The technical scheme of the embodiment establishes a star flash wireless local area network based on a star flash technology and a star topology structure, and is used as an OTA upgrading private network, so that the ECU and the T-BOX are in the same vehicle local area network, the influence of a heterogeneous network on the speed of the whole vehicle OTA can be reduced, and the high concurrency whole vehicle OTA is realized.
