An Innovative Test System for Holistic Vehicle Dynamics Testing 2019-01-0449
In the automotive industry, there is a continued need to improve the development process and handle the increasing complexity of the overall vehicle system. One major step in this process is a holistic approach on both simulation and testing. For example, knowledge of the complete vehicle behavior is getting increasingly important for the development of new control concepts like integrated vehicle dynamics control aiming to improve handling quality and ride comfort. However, with classic test systems, only separated and isolated aspects of vehicle dynamics can be evaluated.
To address these challenges and link simulation and testing even closer, the Institute of Internal Combustion Engines and Automotive Engineering, University of Stuttgart is introducing a new Handling Roadway (HRW) Test System in cooperation with FKFS and MTS Systems Corporation. The HRW allows testing of a vehicle’s combined longitudinal, lateral and vertical characteristics and therefore provides the possibility to supplement road testing with holistic vehicle testing under laboratory conditions.
IVK, FKFS and MTS agreed to establish the HRW system in order to jointly advance the state-of-the-art laboratory evaluation of vehicle dynamics as well as to develop new test applications. The overall goal is to generate a benefit for the automotive industry through innovative scientific approaches. This paper gives an overview of the HRW in its scientific environment of existing test systems at FKFS and the synergies it will generate. A simulation environment is introduced which allows to study the HRW’s intended applications before commissioning of the system. Selected use cases and their respective limitations are presented in more detail. These include testing of the vehicle’s handling characteristics during synthetic and realistic driving maneuvers as well as extended possibilities of evaluating the vehicle’s ride comfort in different driving conditions.
