Vehicle Dynamics: Model-based development and validation of suspension, steering and chassis control systems

Challenges

The increasing level of driving safety combined with a rising demand for ride comfort as well as the development of automated driving functions require powerful and, above all, safe chassis components and systems. This entails an enormous development effort and a high number of test scenarios to find the best setup for suspension, steering and chassis control systems in order to optimize the overall ride comfort and driving experience according to individual preferences.

Solutions

Using virtually build prototypes in the simulation software CarMaker allows for automated and reproducible system and component tests in realistic scenarios – in no less than millions of virtually driven kilometers and numerous available test variations. The open integration and test platform CarMaker enables a flexible and efficient development of steering systems, chassis control systems and suspension design throughout the development process (MIL, SIL, HIL). Already existing tool landscapes can be integrated thanks to a variety of supported standards and interfaces.

Powerful vehicle modeling for realistic virtual tests in real time up to the dynamic limits

The quality of vehicle dynamics simulation essentially depends on the vehicle model: Only an outstandingly precise, high-performance model is capable of correctly and efficiently modeling vehicle dynamics in the virtual world. The model quality of CarMaker has been proven, as CarMaker is widely used in the automotive industry and applied to simulation-based ESC homologation for the virtual approval of vehicle variants.
