Car Connectivity based on Automotive Ethernet MATEnet interconnection system provides bandwidth, flexibility and reliability Page 5 Car Connectivity based on Automotive Ethernet MATEnet interconnection system provides bandwidth, flexibility and reliability TE AUTOMOTIVE /// White Paper | Car Connectivity based on Automotive Ethernet Vehicle-to-X (V2X) technology will deliver more current information about incidents and situations in the near environment of the vehicle. At the same time the data transmitted from individual vehicles ("I have to brake because of an accident ahead") can be uploaded to the cloud and will be processed and refined in the backend from where the validated information is re-distributed to vehicles in the relevant area. This kind of connectivity will establish a swarm intelligence, which can be used to turn traffic into an intelligent system which regulates itself to a degree. Among other trends, the increasing need for neural networks and artificial intelligence (understanding of complex traffic scenarios) in the car brings about an enormous data traffic – both within the car and beyond it (Fig. 1). In an era where vehicle efficiency (higher fuel efficiency and lower CO2 emission) and a general emission reduction are at the top of the priority list, the data pool used for (autonomous) driving is the most valu- able asset because it will give the driver (man) and the car (machine) a clearer idea of how to achieve an efficient, safe and comfortable mobility. Because the data that is relevant for this comes from a growing list of sources, former boundaries between domains (e.g. safety, infotainment and comfort systems) begin to blur. Everything in the vehicle and beyond it is becoming connected. The magnitude of networking is summarized by a McKinsey study, focusing on the connected car: "Today's car has the computing power of 20 modern PCs, features about 100 million lines of code, and processes up to 25 gigabytes of data per hour. As the computing capacity of cars develops further, not only is programming becoming more complex and processing speeds becoming faster, but the entire nature of the technology is shifting. While automotive digital technology once focused on optimizing the vehicle's internal functions, the computing evolution is now developing the car's ability to digitally connect with the outside world and enhance the in-car experience." [1] Once the vehicle becomes an integral part of the IoE, the amount of software in the car will continue to go up – and its scope will widen. One of the drivers behind this trend is cyber security: A connected car needs protection against hacking and data theft. To stay abreast of hacking, the vehicle software will need to be updated, e.g. by software patches eliminating weak spots. This will be done by software-over- the-air (SOTA) distribution, which means even more data traffic to the car and within the car. Fig. 1: Levels of automotive data connectivity
