Due to their complexity and increasing weight, the potential of electrical systems in today's vehicles is now largely exhausted. However, the megatrends autonomous driv-ing and connectivity mean that demands on the sensors and customer features are likely to increase in the future. "Despite a truly spectacular display of innovations, it has not proved possible to minimise the weight and complexity of the wiring harness. What we need here is a radical change, the type of change, for instance, that the zone architecture could provide," said a speaker of a famous German premium manufactur-er at the "Vehicle Electrical Systems" congress held in Ludwigsburg on 13th - 14th March.

This is precisely where the concept study "Vision2025" of the Wiesbaden-based engi-neering service provider EDAG comes into play. Apart from the zone architecture, which could reduce the weight of the wiring harness by approx. 30%, EDAG's "Visi-on2025" also includes a service-oriented concept which, like today's smartphones, could facilitate the implementation of new applications and features in a vehicle throughout its entire life. EDAG's concept study systematically divides the vehicle into different geometrical zones, instead of the domains commonly used today. The zones are interconnected via the automotive Ethernet: this permits high data rates and guarantees real time ca-pability when using TSN.

The talk on the future of the EE architecture given by Gerhard Becker, Head of EE Vehicle Integration at EDAG, was a twofold premiere. Aside from the technical innova-tion, it was the first time that an engineering service provider was invited to speak in Ludwigsburg.
The presentation captured the spirit of the times. EE architecture was a subject that was also taken up by other speakers, from Roland Berger, Bosch and the University of Landshut for instance.

With "Vision2025", the EDAG Group addressed one of the most widely discussed top-ics in the industry. With its innovative concept, the engineering company successfully established its position as a partner capable of helping to shape the EE architecture for the vehicle of the future.
