What is the name of car Ethernet?

1, Name of Vehicle Ethernet
Vehicle Ethernet, as the name suggests, refers to a network system that uses Ethernet technology for data transmission and communication inside a car. It adopts standard Ethernet protocols and physical interfaces, providing high-speed and reliable data transmission capabilities for connecting various electronic control units (ECUs), sensors, actuators, and entertainment information systems of vehicles. Vehicle Ethernet not only inherits the advantages of traditional Ethernet technology, but also optimizes and improves it for the special needs of the automotive industry, making it more suitable for the complex and ever-changing communication environment inside the car.
In the industry, there are various names for in car Ethernet, such as "Automotive Ethernet", "Automotive Ethernet", "IEEE 802.3bw (formerly BroadR Reach)", etc. Although these names are different, they all refer to the same technology - a network system that uses Ethernet technology for data transmission and communication inside a car. Among them, "Automotive Ethernet" is a common term that accurately describes the application areas and technical characteristics of in vehicle Ethernet.
2, Characteristics of Vehicle Ethernet
The reason why in car Ethernet can be widely used in the automotive industry is mainly due to its unique technical characteristics. The following are the main characteristics of vehicle Ethernet:
High bandwidth: Vehicle Ethernet supports data transmission rates of up to 1Gbps or even higher, far exceeding the transmission rate of traditional vehicle networks. This enables it to easily handle the large amount of data transmission needs inside the car, such as high-definition video, audio, sensor data, etc.
Low latency: Vehicle Ethernet achieves low latency data transmission by optimizing network protocols and physical layer technologies. This is crucial for automotive applications that require real-time response, such as autonomous driving, advanced driver assistance systems (ADAS), and so on.
High reliability: The vehicle Ethernet adopts advanced error detection and correction mechanisms, as well as redundant communication paths, to ensure the reliability of data transmission. In addition, it also supports multiple fault diagnosis and recovery technologies, improving the stability of the entire automotive communication system.
Multiple protocol support: Vehicle Ethernet can simultaneously support various protocols or application forms such as AVB (Audio Video Bridging), TCP/IP, DOIP (Diagnostics over IP), SOME/IP (Scalable Service Oriented Midway over IP), etc. This enables it to better adapt to the complex and ever-changing communication needs inside automobiles.
POE (Power Over Ethernet) function: Some car mounted Ethernet also supports POE function, which provides power to connected terminal devices while transmitting data. This eliminates the need for external power lines at the terminal, reduces the complexity of power supply, and improves the flexibility and reliability of the system.
Scalability: Vehicle Ethernet supports multiple network topologies and protocol stacks, making it easy to expand the scale and functionality of internal communication systems in automobiles. With the continuous development of technology, in car Ethernet will also support more new features and functions to meet the future communication technology needs of automobiles.
3, The Application Prospects of Vehicle Ethernet
With the continuous improvement of automotive intelligence and networking, the application prospects of in vehicle Ethernet in the automotive industry are becoming increasingly broad. The following are the main application areas of in vehicle Ethernet:
In car infotainment system: The in car Ethernet can provide sufficient bandwidth to support high-definition video and audio streams, thereby enhancing the entertainment experience of driving and passengers. Through on-board Ethernet, smart phones and other mobile devices can be seamlessly connected with the vehicle system to realize the control of the infotainment system, telephone calls, SMS processing, Internet access and other functions.
Advanced Driver Assistance Systems (ADAS): The onboard Ethernet can connect various sensors and actuators on the car, enabling advanced driving assistance functions such as autonomous driving, collision warning, and lane keeping. These functions require real-time and reliable data transmission and processing capabilities, and in vehicle Ethernet is the ideal choice to meet these requirements.
Vehicle networking: Vehicle Ethernet can support communication between cars and external networks, such as vehicle networking platforms, intelligent transportation systems, etc. Through the Internet of Vehicles technology, cars can obtain real-time external data such as road conditions and weather forecasts, improving drivers' driving efficiency and safety.
Remote diagnosis and vehicle upgrade: The onboard Ethernet can also support remote diagnosis and vehicle upgrade functions. By connecting to a remote diagnostic server or vehicle upgrade server, technicians can remotely monitor and diagnose the operating status of the car, promptly identify and solve problems. At the same time, in car Ethernet can also support online upgrades and updates of vehicle software, improving the intelligence level and performance of the car.
Autonomous driving technology: With the continuous development of autonomous driving technology, in vehicle Ethernet will become one of the key technologies for achieving vehicle intelligence. It can support more complex data processing tasks, provide richer in car services, and even achieve interconnectivity between vehicles. In the future, in vehicle Ethernet will gradually become the backbone network of automotive communication systems, connecting various core domain controllers (such as powertrain domain, body domain, audio domain, ADAS domain, etc.) to form a highly integrated and intelligent automotive network.
