[0060] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0061] With the advancement of technology, automobile products are gradually changing from traditional mechanical tools to a new generation of intelligent terminals with perception and decision-making capabilities. Therefore, the intelligence, networking, electrification and sharing of vehicles have become an inevitable trend in the transformation of the automotive industry. At the same time, the demand for this trend of change has led to the gradual evolution of the electronic and electrical architecture of automobiles from distributed processor architecture to domain controller architecture and central computing platform architecture, and automotive software will become the key to defining the functions of the entire vehicle.

[0062] Moreover, with the continuous advancement of technology, the frequency of domain controller software and system upgrades is also accelerating. In order to achieve the upgrade of domain controller software and systems, in the prior art, a communication connection between the domain controller and the diagnostic device is first established, and then the transmission of the software and the update of the domain controller system are achieved based on traditional diagnostic services.

[0063] However, since the upgrade software size of the domain controller is often hundreds of MB or even several GB, using traditional diagnostic services to achieve software transmission and domain controller system updates may waste a lot of time, resulting in low upgrade efficiency of the domain controller.

[0064] In view of the above problems, in an embodiment of the present application, first, according to the target domain controller upgrade instruction, the vehicle-mounted wireless terminal receives the target domain controller upgrade package sent by the server; then, the vehicle-mounted wireless terminal sends a network communication connection request to the target domain controller, thereby establishing a network communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller; finally, through the network communication connection between the vehicle-mounted wireless terminal and the target domain controller, the target domain controller upgrade package is sent to the target domain controller, so that the target domain controller is flashed and upgraded according to the target domain controller upgrade package. It can be understood that based on the network communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller, the transmission of the target domain controller upgrade package can be realized more quickly, which improves the upgrade efficiency of the target domain controller to a certain extent. Specifically, it is described in detail below in conjunction with specific embodiments and accompanying drawings.

[0065] See also Figure 1 , is a flow chart of a method for upgrading a vehicle-mounted domain controller provided in an embodiment of the present application. Figure 1 As shown, it mainly includes the following steps.

[0066] Step S101: According to the target domain controller upgrade instruction, the vehicle-mounted wireless terminal receives the target domain controller upgrade package sent by the server.

[0067] In the embodiment of the present application, firstly, according to the target domain controller upgrade instruction, the vehicle-mounted wireless terminal receives the target domain controller upgrade package sent by the server. It can be understood that the target domain controller upgrade package is a software package for upgrading the software or system of the target domain controller.

[0068] Specifically, when the user submits the target domain controller upgrade package to the server through the cloud platform, the server will first create an upgrade task; then, the server will send relevant control instructions to the vehicle's control to obtain the data of the vehicle's target domain controller; then the server will detect whether the target domain controller matches the upgrade task; when it is detected that the target domain controller matches the upgrade task, the server will send the target domain controller upgrade package to the vehicle-mounted wireless terminal.

[0069] Of course, when it is detected that the target domain controller matches the upgrade task, for example, the system level of the current target domain controller is the same as the level of the upgrade package, the upgrade task will be terminated.

[0070] In one possible implementation, the target domain controller can ask the owner for upgrade confirmation before upgrading, and ensure that the owner knows and confirms each upgrade through the interaction between the vehicle computer and the mobile phone app. At the same time, the upgrade condition check needs to be performed before upgrading, and the upgrade will only be performed when the vehicle meets the conditions, ensuring that it will not affect the owner's driving and driving safety.

[0071] In a possible implementation, the server has a breakpoint resume capability for recording download points, so that when the download of the target domain controller upgrade package is interrupted, the download is continued from the unfinished point, thereby reducing traffic waste and extending download time.

[0072] Step S102: the vehicle-mounted wireless terminal sends a network communication connection request to the target domain controller.

[0073] In the embodiment of the present application, after the vehicle-mounted wireless terminal receives the target domain controller upgrade package sent by the server, the vehicle-mounted wireless terminal sends a network communication connection request to the target domain controller. The network communication connection may include network communication connections in various formats, and the present application does not specifically limit this.

[0074] Specifically, in a possible implementation, the vehicle-mounted wireless terminal sends a Transmission Control Protocol (TCP) connection request, i.e., a TCP connection request, to the target domain controller, so as to establish a TCP communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller. It can be understood that the TCP communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller can realize the transmission of the target domain controller upgrade package more quickly, and to a certain extent, improve the upgrade efficiency of the target domain controller.

[0075] The target domain controller interface is a DoIP interface, through which the target domain controller can obtain information.

[0076] Step S103: establishing a network communication connection between the target domain controller and the vehicle-mounted wireless terminal according to the network communication connection request.

[0077] In the embodiment of the present application, the vehicle-mounted wireless terminal establishes a network communication connection between the target domain controller and the vehicle-mounted wireless terminal according to the network communication connection request.

[0078] In a possible implementation, after establishing a TCP communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller, the vehicle-mounted wireless terminal sends a routing activation request to the target domain controller, so that a diagnostic communication over Internet Protocol (DoIP) communication connection based on vehicle Ethernet is established between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller, that is, a DoIP communication connection. It can be understood that the DoIP communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller can realize the transmission of the target domain controller upgrade package more quickly, and to a certain extent, improve the upgrade efficiency of the target domain controller.

[0079] To understand the process of establishing a communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller, refer to Figure 2 , which is a schematic diagram of communication connection activation provided by an embodiment of the present application. As shown in the figure, first, TCP network communication is established between the vehicle-mounted wireless terminal and the target domain controller; then, the vehicle-mounted wireless terminal sends a routing activation request to the vehicle-mounted domain controller. Only when the vehicle-mounted wireless terminal receives a positive response to the communication activation, the vehicle-mounted wireless terminal is considered to have established a connection with the vehicle-mounted domain controller and can start diagnostic communication.

[0080] Furthermore, the vehicle-mounted wireless terminal sends a diagnostic request to the vehicle-mounted domain controller. After receiving the diagnostic request, the target domain controller first replies with an acknowledgment (ACK) of the diagnostic request message, i.e., a diagnostic response, and then replies with a corresponding diagnostic response, thus completing the diagnostic interaction between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller.

[0081] Step S104: sending a target domain controller upgrade package to the target domain controller through the network communication connection between the vehicle-mounted wireless terminal and the target domain controller.

[0082] In the embodiment of the present application, the vehicle-mounted wireless terminal sends a target domain controller upgrade package to the target domain controller through a network communication connection between the vehicle-mounted wireless terminal and the target domain controller.

[0083] In a possible implementation, when information is transmitted based on the TCP network communication between the vehicle-mounted wireless terminal and the target domain controller, the target domain controller upgrade package will be split into 1460 small packets by the TCP / IP protocol stack, and then transmitted through the established TCP network communication. The protocol stack of the target domain controller interface will package the received data and perform integrity verification. If there is no problem with the verification, it will send a normal response to the vehicle-mounted wireless terminal. After the device receives the normal response, the transmission of the target domain controller upgrade package is completed.

[0084] In a possible implementation, a secure link is used to transmit the target domain controller upgrade package, thereby ensuring the integrity and security of each file.

[0085] Step S105: flashing and upgrading the target domain controller according to the target domain controller upgrade package.

[0086] In the embodiment of the present application, after the target domain controller receives the target domain controller upgrade package, the target domain controller is flashed and upgraded according to the target domain controller upgrade package.

[0087] In a possible implementation, after the vehicle-mounted wireless terminal sends the target domain controller upgrade package to the target domain controller, the target domain controller obtains the current flash status and sends the flash status to the vehicle-mounted wireless terminal to prompt the user whether the flash upgrade of the target domain controller is completed, thereby improving the user experience to a certain extent.

[0088] In one possible implementation, the upgrade system of the vehicle-mounted domain controller has the ability of differential upgrade, thereby reducing traffic waste and flashing time.

[0089] In a possible implementation, before the upgrade, the vehicle-mounted wireless terminal and the target domain controller will respectively perform upgrade condition verification to ensure the validity of the upgrade.

[0090] In the embodiment of the present application, first, according to the target domain controller upgrade instruction, the vehicle-mounted wireless terminal receives the target domain controller upgrade package sent by the server; then, the vehicle-mounted wireless terminal sends a network communication connection request to the target domain controller, thereby establishing a network communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller; finally, through the network communication connection between the vehicle-mounted wireless terminal and the target domain controller, the target domain controller upgrade package is sent to the target domain controller, so that the target domain controller is flashed and upgraded according to the target domain controller upgrade package. It can be understood that based on the network communication connection between the vehicle-mounted wireless terminal and the vehicle-mounted domain controller, the transmission of the target domain controller upgrade package can be realized faster, which improves the upgrade efficiency of the target domain controller to a certain extent.
