Within the scope of a current research project at the Research Institute of Automotive Engineering and Vehicle Engines Stuttgart (FKFS), the potential for an estimation of vehicle side slip angle and yaw rate arising from online measurement of tire forces is evaluated. Investigations focus on how the vehicle state can be determined, if in addition to wheel speeds and steering angle the tire forces currently acting on the vehicle are known. Different estimation procedures based on inverse tire models, direct integration of vehicle accelerations and closed-loop-observer are discussed. The performance is tested with data from vehicle dynamics simulation.

This paper points out the possibilities and capabilities of modern simulation tools. Furthermore it sensitizes the topic of global view of total system beyond the discipline. Special emphasis is placed on the coupling of tools to form an efficient development and simulation environment. As exemplary implementations a dynamic total vehicle model with active suspensions and with consideration of exact elastic component behavior of the stabilizer bars is presented. The models are all created using modern, commercially available tools. To give another aspect to efficient development and simulation environments some hints to the progress of real time applications are made. Finally preliminary and exemplary simulation results are discussed.
