Vehicle - System Understanding

Driving Dynamics, Driving Comfort and Tires

In the research area of vehicle dynamics, ride comfort and tires, particular importance is attached to the experimental and virtual identification and simulation of vehicle dynamics and comfort-relevant overall vehicle, subsystem and component characteristics. For more than 20 years, long-term research and development cooperations have existed with various automotive, system and component manufacturers as well as industrial service providers and software developers. One of the key points is, for example, to describe and understand the tire under all boundary conditions in real driving operation and road contact as well as with the existing interactions with subsystems in the overall vehicle context and to map them with novel simulation approaches. The existing and emerging complex understanding of the physical chain of effects with the associated new approaches to resolving conflicting goals will enable, for example, demand-oriented concept development, an increase in efficiency in the development and validation process, and the use of innovative development methods.
