Importance and Advantages of Automotive Ethernet?

Honghong has launched an in-vehicle Ethernet solution based on converters and switches to fulfill the automotive sector's need for high-speed, reliable and secure data transmission and system integration. The solution is highly stable and does not modify the packet contents during the conversion process.

As one of the core technologies of in-vehicle network architecture, in-vehicle Ethernet is developing rapidly, with full-duplex data transmission rate up to 100Mbit/s or even 1Gbit/s. It can be transmitted over a single pair of non-masked twisted-pair cables, and at the same time meets the requirements of high reliability, low electromagnetic radiation, low latency, and high-precision clock synchronization. Compared with other automotive buses, in-vehicle Ethernet has higher transmission rates, simplifies in-vehicle wiring, reduces wiring harness costs, and has the advantage of communication diversity, so domestic and foreign host companies are actively investing in related R&D and production.

How are converters and switches used in automotive Ethernet?

Connection and data transfer between auxiliary equipment

In traditional Ethernet and in-vehicle Ethernet, the physical interfaces are not the same, resulting in the devices can not be directly connected, and then need a converter to convert T1 and TX, so as to access to different devices to realize high-speed data transmission.

Realization of port mirroring, route forwarding, etc.

Macronix offers a family of switches that are ideal development tools for testing and validating automotive Ethernet vehicle networks. They can be used to implement MACsec-related functions, VLANs, port mirroring, route forwarding or filtering, deep inspection via TCAM rules, port segmentation, and more.

Meeting the requirements of the automotive industry

The era of intelligent vehicle networking requires the integration of consumer and automobile; the emergence of centralized intelligent ECUs requires faster brush-write rates and iterative computing speeds; the field of autonomous driving requires low-latency, high-precision clock synchronization solutions; and the field of new energy requires more flexible power switching stations for trolleys. All of these areas have already included in-vehicle Ethernet technology as a powerful solution.

Solution Features and Application Scenarios

Sensor Data Acquisition

- Converters to realize physical layer interfaces
- DIP switch to quickly adjust the device's master-slave node, transmission rate, etc.

Bench Test

- Utilizing switches to transfer high rate data to the bench integration system
- Analyze and process data to test the load factor of the equipment.

In-vehicle DV test

- Converting and transferring data using Media Converter devices and switches.
- Viewing and data processing with ANDi software

Application Scenario 1: Sensor Data Acquisition

How can multiple sensors be used to sense the surrounding environment and record data during intelligent driving?

Sensors such as radar, laser radar, cameras, ultrasonic sensors, etc. adopt on-board interfaces, which will collect a large amount of raw data, such as images, point clouds, etc., which is convenient for the analysis of self-driving data and simulation analog.

In order to connect the data from these in-vehicle interfaces to the Datalogger via a hardware device, it is necessary to use Technica converters from Macrohon to realize the conversion of the physical layer interfaces! Convenient DIP switches allow you to adjust the device's master/slave node, transfer rate, and more.

Application Scenario 2: Bench Testing

Bench testing is an indispensable part of vehicle research and development, testing, production, refers to the test will be installed in a dedicated bench for a variety of test processes. This process involves a lot of communication protocols, and not only hardware testing (single-channel requirements), but also the need for multi-channel parallel, in order to improve work efficiency.

Engineers are using the Acer Technica in-vehicle Ethernet switch, which can support up to 8 channels of 1000BASE-T1, with 3 RJ45 interfaces for config, logger and trigger.

Single and dual VLAN tags are used to distinguish between on-board devices with the same MAC address. High-speed data is transmitted to the rack integration system, and data analysis and processing are performed to test the load rate of the devices.

Application Scenario 3: In-vehicle DV Testing

During the production process, the host factory will carry out tests on all levels of components.DV (Design Verification) Testing The purpose of Design Verification Testing is to verify whether the product design meets the specified requirements, and it is a physical test for pre-production or production components. However, in the actual testing session, how does the ECU in the form of Ethernet transmission transmit the data to the PC via in-vehicle protocol?

The solution proposed by Honghong uses in-vehicle components as traditional Ethernet nodes, converts TX to T1 using Media Converter equipment, and then connects to EES, configures switch port mirroring, VLAN tagging, and signal triggering, and performs host computer packet capture processing, frame loss testing, and signal curve graphical viewing through ANDi software.
