DRIVING TOWARD AN EMISSIONLESS FUTURE IN TRANSPORTATION THE CAR IN THE AGE OF CONNECTIVITY AUTOMOTIVE ETHERNET: THE BACKBONE OF CONNECTIVITY With the increase of data production from sensors within the car and the advent of V2V, V2I, and now vehicle-to- cloud (V2C) communication, cars are becoming a major part of the IoT. They are turning into the ultimate mobile device. Automotive Ethernet will play an essential role in its success. For example, real-time communications with other vehicles and infrastructure will provide the car with the best possible database for predictive planning. The vehicle of the future will "know" much more about its immediate environment and the route ahead. ADAS will operate in support of the driver or perform an immediate action based on this increasingly detailed environmental model of the traffic situation ahead. The magnitude of networking is summarized in 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 also 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." 9 TE's MATEnet modular and scalable connectors for automotive Ethernet We provide all the pieces to enable the connectivity stream. So whatever sensor you choose, whatever architecture you choose, whatever you want to keep on the car or bring it to the cloud, we have the connectivity components that help you to manage your system, your architecture, your stream of data. Dominique Freckmann, Manager, Silicon Valley Tech Office Once vehicles become an integral part of the IoT, the amount of software in cars will continue to increase and its scope will expand. A key trend that is expected to affect growth is cyber security. A connected car needs protection against hacking and data theft. To protect and prevent these incidents, the vehicle's software will require regular updates, through software-over-the-air (SOTA) distribution to install patches that eliminate weak spots. These updates will increase the amount of data traffic—both to the car and within the car. Utilizing this wealth of data from all these sources requires high-speed, in-vehicle networking. The challenge is to not only provide more bandwidth for bigger data packages, but also meet the OEMs' different approaches to vehicle electronic/electrical architecture. Electromagnetic Compatibility (EMC) specifications may require different types of interconnection technology as well. Automotive Ethernet therefore requires an intelligent interconnection solution that offers the flexibility, economy, and performance for differing EMC requirement levels. " "
