Electrification, autonomous driving, connectivity inside and outside the vehicle: The onboard electronic network has become the brain of today’s cars. The ever-increasing sharing of data within vehicles and to systems outside of the vehicle raises the complexity and makes the development of electric and electronic systems in vehicles, the so-called E/E development, more and more challenging. PREEvision is a model-based development environment, that faces these challenges, and supports the entire E/E development – from architecture design all the way through to the final wiring harness.
