Description

Technical Field

[0001] This invention relates to the field of automotive electronics technology, and in particular to a gateway routing conversion time testing method, apparatus, device, and storage medium. Background Technology

[0002] With the widespread adoption of in-vehicle network technology, almost all intelligent controllers in automobiles use network bus communication, and CAN bus technology has become the most commonly used in-vehicle network communication technology. As the number of CAN nodes and network segments increases, gateways are also becoming more widely used in many vehicle models. Gateways offer functions such as optimized layout, increased bandwidth, security isolation, and route conversion. When designing an automotive CAN bus gateway, the gateway's route conversion time is a crucial technical indicator, as it determines the real-time performance of the entire network.

[0003] Currently available gateway transition time testing equipment is developed specifically for CAN gateways, but these CAN bus gateway testing methods are complex, expensive, and not universally applicable. As CAN gateways become increasingly complex, they cannot meet the testing needs of all gateways.

[0004] Therefore, how to test the routing conversion time of a gateway under complex gateway testing conditions is a technical problem that urgently needs to be solved. Summary of the Invention

[0010] In conjunction with the first aspect mentioned above, as an optional implementation method, the gateway routing conversion time is determined based on the difference between the absolute time when the gateway sends the message and the absolute time when the gateway receives the message. The gateway routing conversion time is the time difference between when the gateway sends the message and when it receives the message after routing conversion.

[0011] In conjunction with the first aspect mentioned above, as an optional implementation method, the routing table of each gateway message is simulated and modeled using the CAN bus tool, and the simulation model of the routing table of each message is saved on the host computer. The host computer is used to monitor the gateway's sending and receiving message signals and time.

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0032] This application provides a gateway routing conversion time testing method, apparatus, device, and storage medium, which can automate gateway testing. It is applicable to different types of CAN gateways, is simple and practical, highly efficient, has good scalability, and is inexpensive and highly adaptable.

[0033] To achieve the aforementioned technical effects, the general concept of this application is as follows:

[0034] A method for testing gateway route conversion time, the method comprising the following steps:

[0035] S101: Compile routing tables for each gateway message based on the routing and sending relationships of the gateway messages.

[0036] S102: Simulate and model the routing table of each gateway message, and obtain the absolute time of each message.

[0037] S103: Calculate the gateway routing conversion time using the absolute time of each message.

[0038] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1 , Figure 1 The diagram shown is a flowchart of a gateway routing conversion time testing method provided by the present invention. Figure 1 As shown, a flowchart for a gateway route conversion time test includes the following steps:

[0040] Step S101: Compile routing tables for each gateway message based on the routing and sending relationships of the gateway messages.

[0041] Specifically, compiling a routing table for each gateway message based on the routing and receiving relationships of gateway messages can be understood as obtaining gateway messages, determining which network segment the gateway receives from, and then routing to which network segments, thereby determining the routing relationships of gateway messages, and compiling a routing table for each gateway message based on the routing relationships of gateway messages.

[0042] It's important to note that a gateway, also known as an internetwork connector or protocol converter, is a complex network interconnection device that operates above the network layer. It's used only for interconnecting two networks with different high-level protocols. Gateways can be used for both wide area network (WAN) and local area network (LAN) interconnections. A gateway is a computer system or device that acts as a translator. Used between two systems with different communication protocols, data formats, languages, or even completely different architectures, a gateway is a translator. Unlike a bridge, which simply forwards information, a gateway repackages the received information to suit the needs of the destination system.

[0043] A network segment generally refers to the part of a computer network that can communicate directly using the same physical layer devices (transmission media, repeaters, hubs, etc.).

[0044] Routing is the process of determining the end-to-end path of a network when a packet travels from its source to its destination [1]. Routers operate at the network layer of the OSI reference model. Routers achieve network interconnection by forwarding data packets. Although routers can support multiple protocols (such as TCP / IP, IPX / SPX, AppleTalk, etc.), routers typically connect two or more logical ports identified by IP subnets or point-to-point protocols and have at least one physical port. Routers determine the output port and next-hop address based on the network layer address in the received data packet and the routing table maintained internally by the router, and rewrite the link layer data packet header to forward the data packet. Routers reflect the current network topology by dynamically maintaining the routing table and maintain the routing table by exchanging routing and link information with other routers on the network.

[0045] In one embodiment, a gateway message is obtained and the network segment receiving the gateway message is determined. The network segments to which the gateway message is sent are determined through routing. A reason table for each gateway message is compiled based on the network segments to which the gateway message is sent and the network segments to which it is received.

[0046] Step S102: Simulate and model the routing table of each gateway message and obtain the absolute time of each message.

[0047] Specifically, a routing table for each gateway message is written based on the routing relationship of the gateway messages. The routing table for each gateway message is simulated and modeled using a CAN bus tool. The sending of routing messages is simulated using the CAN bus tool, and the reception of the messages output by the gateway routing is monitored to determine the absolute time of each gateway message. The absolute time is the time when the gateway message is normally received, including year, month, day, hour, minute, and second.

[0048] It should be noted that the purpose of simulating and modeling the routing table of each gateway message using the CAN bus tool is to achieve automated gateway testing.

[0049] Gateway under test: The gateway used for testing must contain at least two or more CAN buses and have at least message routing or signal routing functions.

[0050] In addition, it should be noted that the CAN bus tool used to test the gateway's CAN bus tool can be CANoe, VSPY, etc. The CAN bus tool has the ability to record the absolute time of the message, but it must ensure that the number of CAN channels is not less than the number of gateway channels. This ensures that all routing conversion times can be tested at once, improving efficiency.

[0051] In one embodiment, after simulating and modeling the routing table of each gateway message using the CAN bus tool, the host computer simulates and models the routing table of each message and saves it on the host. The CAN bus tool is responsible for simulating the sending of routing messages and monitoring the reception of gateway routing outputs. Then, the routing conversion time is equal to the absolute time of the gateway sending the message minus the absolute time of the gateway receiving the message.

[0052] It should be noted that the host computer is the computer that runs the CAN gateway testing software, used to monitor the gateway's sending and receiving of message signals and timing.

[0053] In one embodiment, ID1 is routing message 1, which is received by CAN2 and routed to CAN4, CAN5, and CAN6 respectively. The CAN tool is used to simulate CAN2 sending a message to the gateway. The absolute time T1R_2 when the gateway CAN2 receives the message is recorded, and the absolute times T1S_4, T1S_5, and T1S_6 when the gateway CAN4, CAN5, and CAN6 send the message are recorded as T1S_4, T1S_5, and T1S_6 respectively. Then, the conversion time of ID1 in the CAN4, CAN5, and CAN6 network segments is T1S_4-T1R_2, T1S_5-T1R_2, and T1S_6-T1R_2 respectively.

[0054] Step S103: Calculate the gateway routing conversion time using the absolute time of each message.

[0055] Specifically, the gateway routing conversion time is determined by the difference between the absolute time the gateway sends the message and the absolute time the gateway receives the message. That is, the routing conversion time is equal to the absolute time the gateway sends the message minus the absolute time the gateway receives the message.

[0056] It should be noted that the gateway routing conversion time is the time difference between when the gateway receives a message, performs routing conversion, and then sends and receives the message.

[0057] Reference Figure 2 , Figure 2The diagram shown is a schematic of a gateway routing conversion time testing device provided by the present invention. Figure 2 As shown, the device includes:

[0058] Module 201: It is used to write routing tables for each gateway message based on the routing and sending relationships of gateway messages.

[0059] Processing module 202: It is used to simulate and model the routing table of each gateway message and obtain the absolute time of each message.

[0060] Calculation module 203: It is used to calculate the gateway routing conversion time using the absolute time of each message.

[0061] Furthermore, in one possible implementation, the calculation module 203 is also used to: determine the gateway routing conversion time based on the difference between the absolute time when the gateway sends the message and the absolute time when the gateway receives the message, wherein the gateway routing conversion time is the time difference between the time when the gateway sends the message and the time when it receives the message after routing conversion.

[0062] Furthermore, in one possible implementation, the processing module 202 is also used to: simulate and model the routing table of each gateway message according to the CAN bus tool, and use the host computer to save the simulated routing table of each message to the host, wherein the host computer is used to monitor the gateway's sending and receiving message signals and time.

[0063] Furthermore, in one possible implementation, the calculation module 203 is also used to: simulate the transmission of routing messages according to the CAN bus tool, monitor the reception of messages output by the gateway routing, and determine the absolute time of each gateway message, wherein the CAN bus tool includes CANoe and VSPY.

[0064] Furthermore, in one possible implementation, the writing module 201 is also used to: obtain gateway messages and determine the network segment receiving the gateway messages; determine the network segment sending the gateway messages through routing; and write each gateway message routing table according to the sending and receiving network segments of the gateway messages.
