The present-day wireless connectivity architecture in a commercial vehicle might be suitable up to the standard Level 2 of automated driving. However, it is still questionable if it will fulfill the performance requirements for Level 3 and above. In this context, we present future connectivity architecture for autonomous vehicles. We provide an example of how two wireless access technologies can be implemented using this architecture. The overall approach is to exploit the power of softwarization, which aligns with the future of in-car computing technologies.
