[0035] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be considered as part of the specification.

[0036] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limitations. Thus, other examples of the exemplary embodiments may have different values.

[0037] The present application provides an OTA upgrade architecture and an OTA upgrade method for a vehicle. The OTA upgrade platform matches corresponding network configurations according to the network topology of each vehicle model, enabling the OTA upgrade platform to adapt to different brands and models, and improving the versatility of the OTA upgrade platform. Further, based on the network configuration corresponding to the vehicle model, the OTA upgrade platform can accurately diagnose the vehicle through the Unified Diagnostic Services (UDS) module. Moreover, the vehicle's instrument panel is communicatively connected to the OTA master control of the vehicle, and the OTA upgrade information is displayed through the instrument panel, solving the user interaction problem caused by the absence of a multimedia device on the vehicle. Additionally, the vehicle can select one of the modules that can be connected to the constant power supply and can be awakened in the off gear for normal refreshing according to its own architecture to integrate the OTA master control, enabling the OTA master control to be quickly integrated into different vehicle terminals, realizing flexible configuration and reliable upgrade of the vehicle terminal.

[0038] As Figure 1 shown, the OTA upgrade architecture for the vehicle provided by the present application includes an OTA upgrade platform and multiple vehicles of different vehicle models ( Figure 1 four vehicles are shown in the example), and the different vehicle models belong to the same brand or different brands. The OTA upgrade platform is provided with network configurations that match the network topology of each vehicle model. The network topology includes the part names, part drawing numbers, diagnostic identity numbers, and network nodes of each module (such as each ECU). Thus, the OTA upgrade platform can flexibly configure the network according to the vehicle's overall vehicle architecture, supporting the expansion and access of different brands and models.

[0039] The OTA upgrade platform contains software programs such as security access algorithms, data erasure, data download, and verification.

[0040] Preferably, the OTA upgrade platform further includes a Unified Diagnostic Services (UDS) module, and the unified diagnostic service module diagnoses the vehicle based on the network configuration corresponding to the vehicle. The OTA upgrade platform issues diagnostic instructions corresponding to each module to the vehicle terminal when the vehicle is powered on. After the vehicle reads the part drawing numbers, software version numbers, etc. of each module, it reports them to the OTA upgrade platform, so that the OTA upgrade platform can understand the software conditions of each module in the actual vehicle state and the refreshable state under various working conditions in real time.

[0041] Preferably, the OTA upgrade platform also collects CAN line message data reported by the vehicle to monitor key signals affecting vehicle upgrade (such as key status, vehicle speed, battery power, handbrake status, gear position, engine speed, vehicle power status, etc.), and understand the vehicle condition in real time.

[0042] Preferably, if the vehicle is not equipped with a gateway, different CAN channels are configured between the OTA upgrade platform and the network nodes of different vehicle modules to achieve flexible configuration from the OTA upgrade platform to the vehicle end. If the vehicle is equipped with a gateway, the gateway distributes the information of the OTA upgrade platform to each network node.

[0043] Preferably, if the vehicle is not equipped with a multimedia device, the vehicle displays OTA upgrade information (including upgrade content, upgrade time required, upgrade progress, and upgrade status, etc.) through the instrument panel (for example, in the form of a pop-up window). The instrument panel is communicatively connected to the OTA master control of the vehicle (for example, through a CAN line) to achieve flexible configuration from the OTA upgrade platform to the vehicle end.

[0044] Preferably, if the vehicle is not equipped with a battery power sensor, the TBOX detects the battery voltage, calculates the remaining power of the low-voltage battery according to the characteristic curve corresponding to the state of charge (SOC) of the battery, and matches the configurable upper and lower high voltages to make the DCDC work. And the OTA upgrade platform understands the battery state based on the battery SOC uploaded by the TBOX.

[0045] On the above basis, for each vehicle model, one module that can be connected to the constant power and can be normally refreshed after being woken up in the off gear can be selected according to its own architecture to integrate the OTA master control into it, so that the OTA master control can be quickly integrated into different vehicle ends to achieve flexible configuration and reliable upgrade of the vehicle end.

[0046] Specifically, the OTA master control provides upgrade operations for the domain control intelligent components, including judging whether it is a differential / full upgrade, performing differential restoration, preparing relevant states and data for the upgrade, and processing the upgrade results. The OTA master control monitors the vehicle interior in real time, monitors the data reported to the OTA upgrade platform, provides upgrade package download services, controls upgrade or rollback, monitors the upgrade progress and status, and controls entry into and exit from the OTA mode; and the OTA master control supports DoCAN and DoIP diagnostic and flashing protocols, including a package download and verification module, a task management module, a task execution and arbitration module, a vehicle condition control module, an upgrade strategy and execution module, a script download and execution module, and a log management and upload module. The OTA master control also transmits files and installation instructions to each module, initiates vehicle status checks and functional dependency checks, performs differential upgrades and rollbacks, reports the upgrade progress and results to the vehicle end and the platform; and provides sub-node transparent transmission capabilities and supports DoCAN diagnostic and flashing protocols. The OTA master control includes functional modules such as package transmission and parsing, task execution, information processing, upgrade condition control, upgrade strategy and execution, rollback retry, and log backhaul.

[0047] As an embodiment, the vehicle's OTA master control is integrated into the central gateway controller, and the central grid controller leads the OTA download, interacts with the cloud, and assumes the function of the OTA master control node. Among them, the OTA master control includes a differential upgrade module. In this embodiment, the system needs to support A / B partition flashing mode.

[0048] As another embodiment, the vehicle's OTA master control is integrated in a telematics BOX (TBOX), and the OTA master control includes a whole package inspection function and a differential upgrade module. In this embodiment, the system needs to support A / B partition flashing mode.

[0049] As another embodiment, the vehicle's OTA master is integrated into the cockpit domain controller or the auxiliary driving domain controller, and the OTA master includes a differential upgrade module. In this embodiment, the cockpit domain controller or the auxiliary driving domain controller is connected to the telematics processor TBOX signal, and the telematics processor TBOX is connected to the Internet via a USB interface to download and store differential packages from the cloud, as well as transparent transmission of sub-nodes under the cockpit domain controller or the auxiliary driving domain controller. In this embodiment, the system needs to support A / B partition flashing mode.

[0050] Based on the above OTA upgrade architecture, this application also provides a vehicle OTA upgrade method, which is applicable to the OTA upgrade platform. Figure 2 As shown, the OTA upgrade method includes:

Among them, the module to be upgraded is determined by the OTA upgrade platform according to the corresponding network configuration of the vehicle model and the actual status of each module.

[0060] S330: Determine whether the user instruction feedback received from the dashboard is an immediate upgrade instruction or a not-upgrade-for-now instruction. If an immediate upgrade instruction is received, execute S340; if a not-upgrade-for-now instruction is received, after the vehicle is powered on next time, re-execute S320.

[0061] S340: Determine whether the upgrade conditions are met (such as determining whether the current vehicle condition meets the pre-upgrade conditions, etc.). If so, execute S350; otherwise, after the vehicle is powered on next time, re-execute S320.
