On June 24, the UNECE World Forum for Harmonization of Vehicle Regulations adopted the long-awaited new UN regulations on cybersecurity and software updates for connected vehicles. In addition to the 54 signatories, which include the US and the EU, South Korea and Japan will also adopt the agreement. The UNECE regulations will come into force from January 2021.
The direction of development is clear: vehicle computers (VCs) and broadband automotive Ethernet will complement today’s vehicle electrical systems with dozens of ECUs connected by CAN, LIN, and FlexRay data buses. The latter remain in demand where high real-time requirements and cyclically recurring functions need to be implemented.
Vehicle computers are about to merge vehicle domains and their software-controlled functions. The ECUs in the periphery are increasingly becoming input/output devices whose actual application takes place at the computer level. The advantages for OEMs are far-reaching: IP is shifted to the central computers. The complexity of E/E architectures is reduced, as is the engineering effort.
