VIRTUAL TIRE DEVELOPMENT FOR NEW ELECTRIC VEHICLE THROUGH DRIVER-IN-THE-LOOP
Thursday 16 May 2024 16:40
In recent years, the push for reduced product development timelines has been more significant than ever: high electrification, intelligent vehicle systems and increased number for car manufacturers are a few key drivers to the same. The front loading of development activities is now a key focus area for achieving faster product development, while subjective evaluation & tuning plays a key role in system specifications optimization in Vehicle Dynamics. This presentation will discuss an approach for parallel development of the tire and vehicle chassis system: the usage of virtual tire models in combination with a real-time vehicle model have enabled the subjective evaluation of vehicle performance in a driver-in-loop simulator. Three loops of tire tuning have been conducted in virtual vehicle development stage, improving the Vehicle Dynamics performance of the vehicle through virtual tire & vehicle tuning before the physical prototypes were built, allowing to take key trade-off decisions related to various chassis components. Finally, the objective measurements of the prototype vehicle as well as the physical tire have a high degree of correlation with the virtual models used.
