TY - GEN A1 - Busch, Jochen A1 - Bestle, Dieter T1 - Optimisation of lateral car dynamics taking into account parameter uncertainties T2 - Vehicle System Dynamics N2 - Simulation studies on an active all-wheel-steering car show that disturbance of vehicle parameters have high influence on lateral car dynamics. This motivates the need of robust design against such parameter uncertainties. A specific parametrisation is established combining deterministic, velocity dependent steering control parameters with partly uncertain, velocity independent vehicle parameters for simultaneous use in a numerical optimisation process. Model-based objectives are formulated and summarized in a multi-objective optimisation problem where especially the lateral steady state behaviour is improved by an adaption strategy based on measurable uncertainties. The normally distributed uncertainties are generated by optimal Latin hypercube sampling and a response surface based strategy helps to cut down time consuming model evaluations which offers the possibility to use a genetic optimisation algorithm. Optimisation results are discussed in different criterion spaces and the achieved improvements confirm the validity of the proposed procedure.
