The development of new vehicles is characterized by a high number of variants and shortened development times. Consequently, an efficiency enhancement of the development process is required particularly in the field of driving dynamics which is strongly based on expert drivers and prototype vehicles. Concerning the development of driving dynamics, efficiency improvements can be carried out by an objective evaluation of vehicle dynamics in simulations. For this purpose, adequate objective evaluation criteria are essential. This paper presents a generic process for the identification of appropriate criteria and demonstrates its usability on the example of the acceleration out of steady-state circular maneuver. Starting point are separate driving tests for vehicle dynamic measurements and subjective evaluation. Based on the measurement data a large set of characteristic values is defined in a generic process. By using statistical methods suitable characteristic values are identified and a dimension reduction of the subjective rating data is achieved. Afterwards, linear relationships between characteristic values and subjective ratings are analyzed to find the appropriate objective evaluation criteria. The application example shows that the generic process is capable to identify new objective evaluation criteria apart from the existing ones for the acceleration out of steady-state circular maneuver. Objective criteria are identified for the subjective rating criteria course guidance, self-steering behavior and stability.
