Communication Beyond Vehicles—Road to Automated Driving

Abstract

Innovation by semiconductor manufacturers is a key requirement for future cars. In communication architectures of today’s high-end cars we see more than one hundred control units, a trend that continues to increase. When we introduce Automated Driving, communications will also have to pass the boundary of the car. A closer look unveils the need for steadily increasing bandwidth, higher fault tolerance, and real-time performance. Data security is an urgent issue, given the prominent car hacks in the US. System costs also come into the equation, as not all solutions are affordable. The following paper shows the state-of-the art car communications and roadmaps its expected evolution showing Vehicle-to-Everything (V2X) as the pre-requisite technology for Automated Driving. It also outlines an approach to categorize the levels of data security in the car and ends with an overview of requirements for secured car communication systems.
