With the continuous development of automotive electronics, in-vehicle network has become a key component of automotive intelligence and interoperability. However, as the complexity of automotive systems increases, the bandwidth and data processing capacity of CAN is no longer sufficient to meet the rapidly increasing data demand. To meet this challenge, Honghong Intelligent Interconnection proposes a panoramic data processing solution based on in-vehicle network capture.<\/p>\n<\/blockquote>\n\n\n\n

Programmatic background<\/strong><\/p>\n\n\n\n

Honghong Electronics Technology Co., Ltd. is a high-tech solution partner dedicated to helping customers succeed through innovation. Focusing on automotive testing and R&D, we have rich technical experience in traditional buses and in-vehicle Ethernet and TSN, aiming to build intelligent in-vehicle networks to improve the efficiency of data transfer and interconnectivity between automotive systems. In order to realize this goal, we have integrated in-vehicle Ethernet and CAN data technology to create a set ofIntegrated in-vehicle data acquisition and processing system.<\/strong><\/mark>Provides engineers with a powerful tool for testing in-vehicle networks.<\/p>\n\n\n\n

Challenges<\/strong><\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Traditional in-vehicle systems rely on the CAN bus as the primary communication protocol, but as the complexity of automotive systems has increased, theThe bandwidth and data processing capacity of CAN is no longer sufficient to meet the rapidly growing data demand.<\/mark><\/strong>Therefore, the challenge of integrating high-bandwidth Ethernet technology with traditional CAN data is faced in the whole vehicle system.<\/p>\n\n\n\n

Solution Implementation and Architecture<\/strong><\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

In order to solve this challenge, Honghong has developed aAutomotive Intelligent Network Convergence Solution, combining theIn-vehicle Ethernet and CAN data capture technology.<\/strong><\/mark>With the in-vehicle Ethernet capture module and CAN capture module, only the PCAN-USB (to simulate CAN message sending) and the laser radar (to act as an in-vehicle Ethernet node) need to be connected to the corresponding capture tool.Network port expansion through the switch to access the PC to record data.<\/strong><\/mark>Used for sensor data acquisition, DV\/PV testing, ECU simulation, and more.<\/p>\n\n\n

Program Advantage<\/strong><\/p>\n\n\n\n

1. AdoptionThe open TECMP agreement.<\/mark><\/strong>Quickly identify and parse payloads.<\/p>\n\n\n\n

2\u3001Adopting advanced technologyConvert CAN data to Ethernet format.<\/mark><\/strong>Realize data integration between the two technologies.<\/p>\n\n\n\n

3. AdoptionHigh bandwidth and high precision time stamp (40ns) for real-time data processing.<\/mark><\/strong>This includes vehicle diagnostic data, sensor data and vehicle control data.<\/p>\n\n\n\n

4. ConvenientReal-time monitoring and adjustment of the vehicle's condition and performance.<\/mark><\/strong>To enhance vehicle safety and driving experience.<\/p>\n\n\n\n

Applications and Data Processing<\/strong><\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Comparing the CAN data simulated by PCAN View software with the Ethernet telegrams collected by the open source tool wireshark, it is easy to see that the CAN telegram ID and Data can be parsed directly.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Get the captured data inserted into the TECMP frame as payload.<\/p>\n\n\n\n

The format of the obtained in-vehicle Ethernet streams satisfies the TECMP protocol (in addition to the traditional frame mode available).<\/p>\n\n\n\n

Honghong's in-vehicle network data capture application case demonstrates how technology convergence can improve the data processing capability and intelligence of vehicle systems. The combination of high bandwidth Ethernet and traditional CAN technology brings more advanced intelligent network solutions to the automotive industry and has a significant impact on vehicle intelligence and future mobility.
