Scaling tire models to different road surfaces using an external IMU and K&C measurements
Paper in proceedings, 2018
Accurate simulation models are required for virtual verification of vehicle dynamics and chassis control functions. The force and moment characteristics of tires depend on the road surface. To achieve good simulation and testing correlation accuracy, an accurate tire model that is representative for the actual road surface is required. This study investigates a cost-efficient method to scale Pacejka 2002 models, based on flat belt measurements, to a real road surface using simple instrumentation and static measurements of a test vehicle. The feasibility of the method is illustrated using measurements, where the propagation of measurement error to model error is investigated.
