Vehicle simulation environment enabling model-based systems engineering of chassis control systems

Abstract

Modern vehicle and mobility concepts result in an increasing vehicle variety and complexity. Subsystems and -components have to be developed in close connection to assess interaction effects. For this work, only the vehicle chassis and its design and development process is to be considered. A modern vehicle chassis contains numerous active control systems, whose purpose include improvements of the vehicle safety, driving dynamics and driving comfort. These systems rely on valid vehicle state information, road condition information, battery degradation states and many more. Further, these systems depend on each other’s system states to avoid unwanted interference.

Considering this, the vehicle sensor technology, the on-board power supply, as well as all chassis control systems to be developed together. Since a state-of-the-art vehicle chassis contains multiple control systems each being parameterised by hundreds of parameters, both complexity and interaction effects exceed the potential of independent, conventional development strategies.
