Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted TBOX testing, and in particular to a 5G-based vehicle-mounted TBOX protocol testing method, equipment, and medium. Background Art

[0002] As new energy vehicles accelerate their intelligent advancement, the collaborative work of TBOX (Telematics Box) and in-vehicle systems (such as in-vehicle infotainment systems), as the core carriers of intelligent connectivity, is becoming increasingly crucial. Under the current technical architecture, both the TBOX and the in-vehicle system are connected to a gateway device via in-vehicle Ethernet, with communications between the TBOX and the in-vehicle system forwarded by the gateway. The TBOX not only provides 4G / 5G network functionality for the in-vehicle system but also facilitates multiple critical service interactions, including vehicle positioning, remote diagnostics, and FOTA firmware upgrades.

[0003] However, the interaction protocols between TBOX and vehicle computers are not standardized within the industry, and different OEMs customize their own proprietary communication protocols. This situation presents significant engineering challenges for TBOX suppliers. Each new OEM project requires tailored adaptation of a new interaction protocol and collaborative development with different vehicle computer suppliers. More critically, during the project development cycle, TBOX is often unable to fully verify the interaction protocols independently, requiring coordinated debugging with the vehicle computer during the vehicle testing phase. This post-verification approach significantly increases project risk and development costs.

[0004] The current testing method for the on-board TBOX vehicle-machine protocol must rely on the physical connection of the actual vehicle-machine system for joint testing. The defects of the existing technology are that not only the development and testing progress of TBOX is completely subject to the development progress and quality status of the vehicle-machine system, but also lead to serious test resource dependence problems on the critical path of the project.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] This application proposes a 5G-based on-vehicle TBOX protocol testing method, which is applied to an on-vehicle TBOX testing system. The on-vehicle TBOX testing system includes an on-vehicle Ethernet converter, a switch, a protocol simulation test platform, a power supply, a signal stand, and a network positioning combination antenna.

[0020] When testing the on-board TBOX, connect the on-board TBOX to the on-board Ethernet converter, connect the on-board Ethernet converter to the switch, connect the switch to the protocol simulation test platform, connect the power supply to the protocol simulation test platform, connect the signal stand to the protocol simulation test platform, and connect the network positioning combination antenna to the protocol simulation test platform.

[0021] The in-vehicle Ethernet converter is used to convert the dedicated in-vehicle Ethernet interface into a standard Ethernet interface (such as a standard RJ45 Ethernet interface). The switch supports the access of multiple TBOX devices, which means that multiple TBOX devices can be tested in parallel at the same time. The power supply is used to simulate the power supply environment of the entire vehicle. The signal test bench is used to simulate the wiring harness interface of the entire vehicle. The network positioning combination antenna is used to provide a stable and reliable network connection channel and satellite positioning signal to ensure the effectiveness of communication and positioning function testing.

[0022] The protocol simulation test platform is used to test TBOX equipment. It has built-in private vehicle-machine interaction protocols of multiple manufacturers. It can automatically identify the protocol type of TBOX, create corresponding protocol simulation instances in real time, execute automated test case scripts in parallel, automatically summarize the results of each test instance, and generate detailed and traceable test reports. By building an automated test host computer platform (protocol simulation test platform) independent of the actual vehicle-machine system, the interactive behavior of the vehicle-machine system can be fully reproduced through protocol simulation technology to achieve full-cycle independent verification of the TBOX vehicle-machine interaction protocol.

[0023] Among them, such as Figure 1 As shown, the 5G-based vehicle-mounted TBOX protocol testing method of this application includes: Step S100: Connect the TBOX device to be tested to the switch via the vehicle-mounted Ethernet converter, and connect the switch to the protocol simulation test platform; The TBOX device to be tested is the test object.

[0024] like Figure 2As shown in the figure, if there are multiple TBOX devices to be tested, and the manufacturers and protocol types of the multiple TBOX devices to be tested are different, this system can test multiple TBOX devices to be tested at the same time, and connect each TBOX device to be tested to the switch through an in-vehicle Ethernet converter, so that each TBOX device to be tested can be tested in parallel through the protocol simulation test platform.

[0025] Step S200: Configuring the TBOX device to be tested and the protocol simulation test platform to be in the same network segment; Furthermore, in response to being configured as the same network segment as the protocol simulation test platform, the TBOX device to be tested adopts an active discovery mechanism based on IP multicast (implemented through the IGMP protocol (Internet Group Management Protocol), whose core function is to dynamically manage the joining and leaving of group members) to periodically broadcast the key identity information of the TBOX device to be tested to the predefined multicast address and port.

[0026] The key identity information of the TBOX device to be tested includes the vehicle identification number (VIN) of the TBOX device to be tested, the protocol type of the vehicle-machine interaction protocol currently running on the TBOX device to be tested, and the protocol service listening port of the TBOX device to be tested.

[0027] Step S300: The protocol simulation test platform identifies the vehicle-machine interaction protocol run by the TBOX device to be tested, so as to generate a protocol simulation instance corresponding to the vehicle-machine interaction protocol run by the TBOX device to be tested; The protocol simulation instance is used to simulate the vehicle-side behavior logic of the corresponding vehicle-machine interaction protocol.

[0028] Furthermore, in step S300, the protocol simulation test platform identifies the vehicle-machine interaction protocol run by the TBOX device to be tested, so as to generate a protocol simulation instance corresponding to the vehicle-machine interaction protocol run by the TBOX device to be tested, including steps S310 to S330: Step S310: When the protocol simulation test platform obtains the broadcast message of the TBOX device to be tested, a mapping relationship is established between the Internet Protocol address (IP address) of the TBOX device to be tested, the protocol type of the vehicle-machine interaction protocol currently running on the TBOX device to be tested, and the protocol service listening port of the TBOX device to be tested; After the protocol simulation test platform is configured with the same network segment (same IP subnet address) as the TBOX device to be tested, it acts as a listener and joins the same multicast group as the TBOX device to be tested. Once the protocol simulation test platform receives the broadcast message from the TBOX device to be tested, it can parse and establish a mapping relationship between the IP address and protocol type of the TBOX device to be tested, as well as the protocol service listening port, in real time. This method realizes the discovery of the TBOX device to be tested and the automatic identification of the protocol, eliminating the need for manual configuration of each connected TBOX device to be tested, greatly simplifying the test preparation process.

[0029] Step S320: The protocol simulation test platform dynamically loads the protocol stack library corresponding to the identified vehicle-machine interaction protocol running on the TBOX device to be tested according to the protocol type. Step S330: The protocol simulation test platform creates an independent and isolated protocol simulation instance corresponding to the vehicle-machine interaction protocol run by the TBOX device to be tested for the multicast group where the TBOX device to be tested is located.

[0030] Step S400: The protocol simulation test platform sends the preset test case corresponding to the protocol simulation instance to the protocol simulation instance; Furthermore, in step S400, the protocol simulation test platform sends the preset test case corresponding to the protocol simulation instance to the protocol simulation instance, including steps S410 to S420: Step S410: The protocol simulation test platform determines a test case corresponding to the protocol simulation instance from a plurality of preset general test cases according to the type of the protocol simulation instance corresponding to the TBOX device to be tested; Step S420: Send the test case corresponding to the protocol simulation instance to the protocol simulation instance.

[0031] Select or import a preset universal test case set on the protocol simulation test platform. This universal test case set includes several common test cases, such as vehicle status query, location services, remote diagnosis, and FOTA firmware upgrade. The protocol simulation test platform intelligently distributes the corresponding test cases to the corresponding instances based on the type of each protocol simulation instance. A universal test case set can be distributed to all compatible protocol instances simultaneously to ensure parallel testing of multiple TBOX devices under test.

[0032] Step S500: The protocol simulation instance performs a protocol interaction test on the TBOX device to be tested according to the test case to obtain a test result corresponding to the TBOX device to be tested; Furthermore, in step S500, the protocol simulation instance performs a protocol interaction test on the TBOX device to be tested according to the test case to obtain a test result corresponding to the TBOX device to be tested, including steps S510 to S530: Step S510: triggering the execution engine of the test case to drive the protocol simulation instance to execute the test steps included in the test case to perform a protocol interaction test on the TBOX device to be tested; Each protocol simulation instance independently performs protocol interaction with the corresponding TBOX device to be tested, sends instructions, receives responses and verifies results.

[0033] Step S520: The protocol simulation instance sends the test log generated during the protocol interaction test of the TBOX device to be tested to the protocol simulation test platform; Step S530: The protocol simulation test platform integrates the test information in the test log to obtain the test result corresponding to the TBOX device to be tested.

[0034] Among them, the test information in the test log includes test instruction information, test response information, test timestamp information, and test status. Each protocol simulation instance records detailed logs in real time during execution. After the test execution of all TBOX devices to be tested is completed, the protocol simulation test platform will automatically aggregate the test results of each protocol simulation instance, classify them by device / IP / protocol type, and generate a structured test report, which clearly displays the test details, pass rate, problem points and log snapshots of each TBOX device, thereby improving the automation level and test efficiency of TBOX device testing.

[0035] Furthermore, the TBOX vehicle-machine interaction protocols defined by different OEMs, and even by different vehicle models within the same OEM, vary significantly in message structure, instruction sets, and communication mechanisms (request / response, publish / subscribe). Therefore, to achieve universal test case compatibility, a protocol adapter must be developed for each supported proprietary protocol. This protocol adapter has two core interfaces: an upper-level interface that exposes a set of standardized, protocol-independent functional interfaces that abstract the core business functions of the TBOX device; and a lower-level interface that interfaces with specific proprietary protocols and handles protocol-specific functions such as encoding and decoding, serialization / deserialization, and communication session management. Test case scripts are written only for standardized functional interfaces. Therefore, regardless of the underlying protocol, as long as the adapter correctly implements these standard interfaces, the same test case script can be run on that protocol, improving test reusability.

[0036] In addition, if Figure 3As shown, for the very few proprietary protocols with distinct functional logic or that cannot be fully mapped to standard interfaces, a dedicated protocol adapter can be written. This adapter distinguishes differences within the protocol adapter using OEM or vehicle model fields, and handles these unique logic within the test case. The test case itself can still maintain a large degree of commonality, with only differentiated calls for specific parts. Through standardized interface design, dynamic multi-protocol adaptation, and parallel testing mechanisms, functional verification of TBOX devices from different manufacturers and protocol types can be efficiently supported, significantly improving the automation and execution efficiency of in-vehicle terminal testing.

[0037] The 5G-based on-vehicle TBOX protocol testing method of the present invention is executed by an on-vehicle TBOX testing system, which is composed of an on-vehicle Ethernet converter, a switch, and a protocol simulation test platform. When testing the TBOX device to be tested, the TBOX device to be tested is connected to the switch through the on-vehicle Ethernet converter, and the switch is connected to the protocol simulation test platform. The TBOX device to be tested and the protocol simulation test platform are configured as the same network segment to ensure the interoperability of the second-layer network. The protocol simulation test platform identifies the vehicle-machine interaction protocol run by the TBOX device to be tested to generate a protocol simulation corresponding to the vehicle-machine interaction protocol run by the TBOX device to be tested, which is used to simulate the vehicle-machine behavior logic of the corresponding vehicle-machine interaction protocol. Instance, the protocol simulation test platform then sends the test case corresponding to the protocol simulation instance to the protocol simulation instance. The protocol simulation instance performs protocol interaction test on the TBOX device to be tested according to the test case to obtain the test result corresponding to the TBOX device to be tested. By building an on-board TBOX test system to eliminate the physical dependency of the on-board TBOX on the vehicle system, it is possible to simultaneously access multiple on-board TBOXs of different manufacturers and different protocol types for testing, dynamically identify and adapt to multiple protocols, execute common test cases in parallel and generate test reports based on the test results, achieving the effect of one-time writing and full protocol coverage, thereby improving the automation level and test efficiency of the on-board TBOX test and facilitating the expansion and access of new TBOX vehicle-machine interaction protocols.
