Abstract

Vehicle design with respect to steering feel and steering vibration is challenging for many reasons. One of them is that several subsystems need to be considered simultaneously. These are the front axle, the power-assisted steering gear and the steering column. Typically, they are developed separately by different departments or external suppliers. Therefore, the requirements, which are usually imposed on the vehicle level, i.e. the coupled system, have to be reformulated on the level of subsystems. In order to enable robust concurrent design of subsystems from the beginning, a design method is proposed that relies on so-called solution spaces. Here, a solution space defines a permissible range of subsystem parameters that ensures that a specified set of requirements is satisfied on the superior system level. It is constructed to be as large as possible in order to provide maximum flexibility for subsystem design, parameter variance or uncertainty. As a main benefit, the permissible parameter ranges are independent of each other and the subsystems are decoupled. In this work, objective requirements on the steering subsystem are derived followed by the computation of solution spaces for important design parameters using meta models and stochastic sampling. Finally, the results are validated with a detailed simulation model.
