[0039] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0040] In the prior art, vehicles have complex high-bandwidth applications, and improve safety and reduce fuel consumption, while providing a rich network experience for drivers and passengers. New digital systems are one of the most important factors for success in a highly competitive market, but this puts forward new requirements for automobile manufacturers: the need to ensure that these in-vehicle networks provide the best service quality and reliability. When the domain controller is used as the object under test, the domain controller can be connected to a virtual test platform or test system, so that the domain controller can be fully tested in an efficient and low-cost manner. It is a development and testing technology for complex device controllers. By connecting to a real controller, a real-time simulation model is used or partially used to simulate the controlled object and the system operating environment to achieve simulation testing of the entire system. An embodiment of the present invention proposes a communication test system based on in-vehicle Ethernet, which can realize the controllable subscription process of SOME / IP SD between the domain controller and the simulation node. The following reference Figure 1-Figure 4 A communication test system based on in-vehicle Ethernet according to an embodiment of the present invention is described.

[0041] In some embodiments of the present invention, Figure 1 FIG. 4 is a block diagram of a communication test system based on vehicle Ethernet according to an embodiment of the present invention.

[0042] The communication test system 1 based on vehicle Ethernet includes a lower computer 10 , a switch 20 , a domain controller 30 and a host computer 40 .

[0043] Specifically, it can be combined Figure 1 and Figure 2 Understand the lower computer 10 of the present invention, as Figure 2 FIG. 1 is a block diagram of a lower computer according to an embodiment of the present invention. Figure 1 The HIL simulation platform 101 and the board box 102 are not shown.

[0044] Among them, Figure 2 As shown, the lower computer 10 includes a HIL simulation platform 101 and a board box 102. It is understandable that a real-time simulation system is provided in the HIL simulation platform 101, and the real-time simulation system is an RTI real-time machine, which can perform high-reliability real-time detection with a response time of ≤100us. The simulation model is run in the real-time simulation system to simulate the running state of the vehicle. By receiving the signal sent by the object under test, that is, the domain controller 30, and simulating the signal received by the object under test, the simulation environment run by the real-time simulation system can form a closed loop with the object under test, thereby providing the necessary basis for HIL automated testing.

[0045] The board box 102 is connected to the HIL simulation platform 101, wherein at least one of an Ethernet card, an I / O board card and a CAN card is arranged in the board box 102. The Ethernet card is used to transmit Ethernet signals, the I / O board card is used to transmit digital signals and / or analog signals, and the CAN card is used to transmit CAN signals.

[0046] The domain controller 30 refers to at least one server in the "domain" mode that is responsible for the verification of each computer and user connected to the network, and can also be called DC (Domain Controller). The I / O port of the domain controller 30 is suitable for communication with the lower computer 10. Among them, in the I / O interface communication test solution, the I / O interface can be used as a simulated resistance output signal channel, an analog input and output channel, a PWM input and output channel, and a digital input and output channel, and can be used to perform I / O communication tests.

[0047] The switch 20 can provide an exclusive electrical signal path for any two network nodes connected to the switch 20, so that data transmission between multiple port pairs can be achieved at the same time. Specifically, the switch 20 is provided with multiple Ethernet interfaces, which are respectively used to connect to the lower computer 10, the upper computer 40 and the domain controller 30. The switch 20 supports multi-port 100 / 1000BASE-T1 conversion, the message delay is less than 2 microseconds, and the message can be timestamped with a 40ns accuracy.

[0048] The upper computer 40 is connected to the lower computer 10 and the switch 20 via a network cable, which is at least used to build the first environment simulation model and the second environment simulation model and load them into the lower computer 10, and control the lower computer 10, the switch 20 and the domain controller 30 via the network cable to perform the vehicle Ethernet communication test.

[0049] Specifically, the HIL simulation platform 101 uses a workstation as the host computer 40. The host computer 40 is connected to the domain controller 30 via the vehicle Ethernet switch 20. The host computer 40 can interact with each node and capture communication messages between nodes in a mirroring manner.

[0050] Furthermore, the real-time simulation system configured in the HIL simulation platform 101 is used to run the first environment simulation model and the second environment simulation model. The first environment simulation model is at least used to simulate the SOME / IP SD subscription logic of the simulation node, establish a service-based connection with the domain controller 30, and simulate the vehicle environment to form a closed-loop system with the domain controller 30. The second environment simulation model is at least used to simulate the SOME / IP SD subscription logic of the domain controller 30 when it is determined that the domain controller 30 lacks the SOME / IP SD function.

[0051] Among them, it can be combined Figure 3 Understand the first environment simulation model and the second environment simulation model of the embodiment of the present invention. Figure 3 4 is a block diagram of a first environment simulation model and a second environment simulation model according to an embodiment of the present invention.

[0052] Specifically, the first environment simulation model is the main model, and the second environment simulation model is the secondary model. The first environment simulation model may include a power control module, a vehicle dynamics model, a driver control model, an I / O simulation model, a CAN communication model, and a first ETH communication model, etc. Specifically, the power control module is used to set the output voltage value and the current value; the vehicle dynamics model is mainly composed of sub-simulation modules such as a battery module, a motor module, a transmission module, a vehicle module, a DCDC module, a vacuum pump module, and an energy consumption calculation module; the function of the driver model is to simulate the driver's operation of some operable devices of the vehicle and the influence of the external environment on the vehicle, as a necessary input for the dynamics simulation model. The I / O simulation model is used to simulate I / O signals; the CAN communication model is used to simulate CAN messages; the first ETH communication model is used to simulate the SOME / IP SD subscription process and the SOME / IP message. The embodiment of the present invention aims to establish SOME / IP communication between the domain controller 30 and the simulation node.

[0053] The second environment simulation model at least includes a second ETH communication model, which is used to simulate the SOME / IP message and SOME / IP SD subscription function of the domain controller 30. The function of the second ETH communication model is to simulate the SD subscription process of the domain controller 30 when the domain controller 30 lacks the SOME / IP SD subscription function, thereby completing the service subscription with the simulation node. In this case, the SOME / IP communication between the domain controller 30 and the simulation node is actually implemented by the first environment simulation model and the second environment simulation model.

[0054] According to the communication test system 1 based on vehicle Ethernet proposed in the embodiment of the present invention, based on the architecture of the upper computer 40, the lower computer 10, the domain controller 30 and the switch 20, the communication connection between the upper computer 40 and the domain controller 30, and between the lower computer 10 and the domain controller 30 can be established simultaneously by configuring the switch 20 and providing multiple Ethernet interfaces, so that the upper computer 40 can control the lower computer 10 to perform vehicle Ethernet communication test through the switch 20 and the domain controller 30. And by configuring and running the dual model, it can simulate the SOME / IP SD subscription logic of the simulation node and the SOME / IPSD subscription logic of the domain controller 30, which can meet the Ethernet communication test of the domain controller 30 that lacks the SOME / IP SD function, and realize the controllability of the subscription process of the SOME / IP SD between the domain controller 30 and the simulation node.

[0055] In addition, the network hardware used by the vehicle-mounted Ethernet-based communication test system 1 proposed in the embodiment of the present invention to support Ethernet communication testing is mainly Ethernet card and switch 20, which can greatly reduce the equipment cost compared with the use of CANOE and other devices in the prior art.

[0056] In some embodiments of the present invention, Figure 4 As shown, it is a block diagram of a communication test system based on vehicle Ethernet according to another embodiment of the present invention, wherein the multiple Ethernet interfaces on the switch 20 include a first Ethernet interface a1, a second Ethernet interface a2, a third Ethernet interface a3 and a fourth Ethernet interface a4.

[0057] Among them, the first Ethernet interface a1 is suitable for communication connection with the simulation interface b1 of the first environment simulation model in the lower computer 10. The first Ethernet interface a1 is a SOME / IP communication interface. When the first environment simulation model simulates the SOME / IP SD subscription logic of the simulation node, the first Ethernet interface a1 can be used to transmit the Ethernet SOME / IP communication message of the simulation node of the first environment simulation model and the data sent by the domain controller 30.

[0058] And, the second Ethernet interface a2 is suitable for communication connection with the simulation interface b2 of the second environment simulation model in the lower computer 10. The second Ethernet interface a2 is a SOME / IP communication interface. When the second environment simulation model simulates the SOME / IP SD subscription logic of the domain controller, the second Ethernet interface a2 can be used to transmit the Ethernet SOME / IP communication message of the second environment simulation model simulating the domain controller and the Ethernet SOME / IP communication message of the first environment simulation model simulating the simulation node.

[0059] The third Ethernet interface a3 is suitable for communication connection with the host computer 40. The third Ethernet interface a3 is a SOME / IP communication interface, which can be used to transmit Ethernet SOME / IP communication messages to the host computer 40, and receive the switch communication interface configuration instruction sent by the host computer 40. When the switch 20 responds to the switch communication interface configuration instruction, it can reconfigure the conduction status of the first Ethernet interface a1, the second Ethernet interface a2, the third Ethernet interface a3 and the fourth Ethernet interface a4 inside the switch 20. Further, the third Ethernet interface a3 is required to have the ability to mirror the Ethernet SOME / IP messages sent and received by the first Ethernet interface a1 and the second Ethernet interface a2, and the interface is connected to the host computer 40 through a network cable.

[0060] The fourth Ethernet interface a4 is suitable for communication connection with the domain controller 30. That is, the fourth Ethernet interface a4 of the switch 20 is connected to the Ethernet interface of the domain controller 30 through an Ethernet cable, so as to realize information transmission with the domain controller 30.

[0061] More specifically, the Ethernet cable used to connect the lower computer 10 with the first Ethernet interface a1 and the second Ethernet interface a2, and the Ethernet cable used to connect the domain controller 30 with the fourth Ethernet interface a4, can both adopt ETH-T1 Ethernet cable, which is used to realize the information transmission between the lower computer 10 and the switch 20 and the domain controller 30. And, the Ethernet cable used to connect the third Ethernet interface a3 and the upper computer 40 can adopt ETH-TX Ethernet cable. Among them, ETH-T1 Ethernet cable and ETH-TX Ethernet cable are both used to transmit Ethernet signals. Specifically, ETH-T1 usually refers to the T1 circuit of 1.544Mbps, which is a transmission medium with a slower transmission rate, mainly used for transmitting voice and data, and is usually used for long-distance transmission. ETH-TX is a physical layer transmission medium with a faster transmission rate than ETH-T1, which can transmit data of different rates such as 10Mbps, 100Mbps, 1Gbps, etc.

[0062] Further, the first Ethernet interface a1, the second Ethernet interface a2, the third Ethernet interface a3 and the fourth Ethernet interface a4 set by the switch 20 and the Ethernet interface of the domain controller 30 are the same VLAN (Virtual Local Area Network), and when the first environment simulation model simulates the SOME / IP SD subscription logic of the simulation node, the first Ethernet interface a1 and the second Ethernet interface a2 inside the switch 20 are not connected, and the first Ethernet interface a1 and the third Ethernet interface a3 inside the switch 20 are connected. And, when it is determined that the domain controller 30 lacks the SOME / IP SD function, the first Ethernet interface a1 and the second Ethernet interface a2 inside the switch 20 are connected.

[0063] In some embodiments of the invention, Figure 4 As shown, the vehicle Ethernet-based communication test system 1 also includes a first CAN channel 50 and a second CAN channel 60. It can be understood that the CAN card in the card box 102 of the test system 1 proposed in the embodiment of the present invention actually integrates two CAN cards corresponding to the first CAN channel 50 and the second CAN channel 60 respectively.

[0064] Specifically, the first CAN channel 50 is used to connect the lower computer 10 and the domain controller 30, and the first CAN channel 50 is used to transmit the CAN message of the model simulation sent by the lower computer 10 and the CAN communication signal sent by the domain controller 30. Specifically, when performing the CAN communication test, the upper computer 40 controls the lower computer 10 through the network cable, and the lower computer 10 controls the domain controller 30 through the first CAN channel 50. Therefore, the Ethernet-based communication test system 1 proposed in the embodiment of the present invention connects the lower computer 10 and the domain controller 30 by setting the first CAN channel 50 to receive and send CAN communication signals, so that the test system 1 can realize the CAN communication test of the domain controller 30. According to the above embodiment, it can be seen that the first CAN channel 50 of the embodiment of the present invention will not interfere with the Ethernet and I / O communication equipment, so that while performing the CAN communication test on the domain controller 30, the upper computer 40 can control the lower computer 10 to simultaneously realize the SOME / IP communication test and I / O communication test of the domain controller 30.

[0065] And, the second CAN channel 60 is used to connect the host computer 40 and the domain controller 30, and the second CAN channel is used to transmit the CAN diagnostic message, CAN calibration message and CAN diagnostic signal sent by the host computer 40 and the domain controller 30. The host computer 40, the switch 20, the domain controller 30 and the second CAN channel 60 together constitute the hardware architecture of the CAN communication diagnostic test. Specifically, the second CAN channel 60 is used to connect the host computer 40 and the domain controller 30, and the second CAN channel 60 is used to transmit the CAN diagnostic message, CAN calibration message and CAN diagnostic signal sent by the host computer 40 and the domain controller 30; the host computer 40 is used to perform at least one of the CAN communication diagnostic test and the calibration automation test on the domain controller 30 through the second CAN channel 60.

[0066] Understandably, calibration refers to the process of fine-tuning various vehicle systems to ensure they perform to design specifications. This may involve adjusting software settings, calibrating sensors, or modifying mechanical components to achieve the expected results; calibration ensures that different vehicle systems work in harmony and efficiently. Proper calibration can optimize fuel consumption, maximize performance, reduce emissions, and enhance safety features. Without regular calibration, vehicles may not perform as expected, resulting in inefficiencies and potential safety risks. Calibration in the automotive industry plays a vital role in ensuring that vehicles operate at optimal performance and safety.

[0067] According to the Ethernet-based automated test system 1 proposed in the embodiment of the present invention, by setting the second CAN channel 60 to connect to the host computer 40, for UDSonCAN diagnostic messages and calibration messages, etc., the test system 1 can implement CAN communication diagnostic test and calibration test. According to the above embodiment, the second CAN channel 60 of the embodiment of the present invention and the first CAN channel 50, Ethernet, and I / O communication equipment will not interfere with each other, so while performing CAN communication diagnostic test and / or calibration test on the domain controller 30, the SOME / IP communication test and I / O communication test of the domain controller 30 can also be implemented at the same time, that is, multiple communication tests and multiple diagnostic tests and calibration tests can be implemented at the same time, which can greatly improve the test efficiency.

[0068] In other embodiments of the present invention, the board box 102 of the embodiment of the present invention can be further understood in combination with the above-mentioned embodiments. Specifically, the Ethernet card is suitable for being communicated and connected with the first Ethernet interface a1 and the second Ethernet interface a2 of the switch 20, and the Ethernet card is used to send Ethernet test messages and / or receive Ethernet signals sent by the domain controller 30. The I / O board card is suitable for being communicated and connected with the I / O port of the domain controller 30, and the I / O board card is used to send and receive I / O signals; the CAN card is suitable for being communicated and connected with the first CAN channel 50, and the CAN card is used to send model simulation CAN messages and / or receive CAN communication signals sent by the domain controller 30.

[0069] In some embodiments of the present invention, Figure 3 and Figure 4 Understanding the network cables of the embodiment of the present invention. The network cables include a first network cable n1, a second network cable n2, and a third network cable n3.

[0070] In some embodiments of the present invention, Figure 4 As shown, the host computer 40 is configured with a model configuration module 401 , a communication interface configuration module 402 , a switch configuration module 403 and a communication test module 404 .

[0071] The model configuration module 401 is connected to the HIL simulation platform 101 via the first network cable n1, and is used to load the first environment simulation model and the second environment simulation model into the lower computer 10. The model configuration module 401 can be commercial software such as MATLAB software, which is used for the development and offline simulation of dual models.
