Summary

This chapter mainly covered what lies beyond UDS and the need for a new diagnostic protocol, by examining UDS limitations and SOVD internals and providing examples. Additionally, it compared UDS and SOVD based on key aspects at the end of the chapter. At this time, you should have a fair understanding of SOVD and its practical implementation and other details.

So far, we have explored the ongoing evolution of vehicle architecture, which encompasses various standard automotive frameworks, such as Classic AUTOSAR, Adaptive AUTOSAR, and hypervisor, supporting guest virtual machines. At the core of modern vehicle architectures lies SOVD, which plays a pivotal role in diagnostics for modern vehicles.

As vehicles become more connected, ensuring the security of remote diagnostics systems is crucial. Cybersecurity measures, such as encryption and secure communication protocols, protect sensitive vehicle data from unauthorized access.

In the next chapter, we will explore cybersecurity...
