Control Design for Vertical Vehicle Dynamics through Active Roll Bars and Continuously Variable Dampers

Project Completed - Contact: ftm(at)ftm.mw.tum.de

Motivation 

The vertical dynamics of a vehicle have a significant influence on driving safety and driving comfort. Rolling and pitching behaviour are movements of the body which the driver perceives strongly and which he includes significantly in his subjective evaluation of the driving behaviour.
Modern active chassis systems enable the vertical dynamics to be influenced in a targeted manner and to approach the resolution of the conflict of objectives between driving safety and driving comfort. The optimal control of combined systems is the basis for an optimal subjective evaluation of the driver, which is the focus of the development of new suspension systems

Goal

Suspension systems with adaptive damper characteristics and active stabilisers are already in series production. However, a combined concept for the optimum control of active dampers and active stabilisers in combination has not yet been fully developed. The control concept to be developed is intended to combine the potentials of both systems optimally in terms of subjective evaluation and energy efficiency.
