This paper introduces an innovative methodology for the evaluation of tire and steering systems, leveraging the integration of the full threedimensional tire model FTire with the well-known Pfeffer steering model under hard real-time conditions on a Driver-in-the-Loop system. The primary objective is to enhance the accuracy in depicting tire-road interactions, including the differentiated feedback communicated to the steering wheel achieved through high accurate modeling of the steering system. A very realistic steering feel emulator is employed to replicate complex sensory feedback inherent in the driver's interaction with the steering wheel. A thorough description of the procedural implementation and subsequent validation of the proposed methodology is provided. Additionally, a first case study is presented, illustrating the advantages transmitted by the consideration of a three-dimensional contact patch and the incorporation of the complete tire dynamics. This integrative approach enables a comprehensive evaluation of both tire and steering system performances across diverse road surfaces and various driving maneuvers.

摘要

This paper introduces an innovative methodology for the evaluation of tire and steering systems, leveraging the integration of the full threedimensional tire model FTire with the well-known Pfeffer steering model under hard real-time conditions on a Driver-in-the-Loop system. The primary objective is to enhance the accuracy in depicting tire-road interactions, including the differentiated feedback communicated to the steering wheel achieved through high accurate modeling of the steering system. A very realistic steering feel emulator is employed to replicate complex sensory feedback inherent in the driver's interaction with the steering wheel. A thorough description of the procedural implementation and subsequent validation of the proposed methodology is provided. Additionally, a first case study is presented, illustrating the advantages transmitted by the consideration of a three-dimensional contact patch and the incorporation of the complete tire dynamics. This integrative approach enables a comprehensive evaluation of both tire and steering system performances across diverse road surfaces and various driving maneuvers.
