Abstract
Forces developing at tire-road interaction provide extremely important information concerning vehicle performance, both for handling and drivability. Such quantities are often utilized during vehicle benchmarking, for the purpose of analyzing the effect of design changes on the behavior of the car. In particular, experimental results can exhibit how tiny design modifications, resulting in equally small variations of the transient built-up of wheel lateral forces, may yield perceptible effect on the overall performance of the vehicle. Unfortunately, the equipment required for measuring such dynamics (wheel force transducers - WFTs) it is very expensive and testing the vehicle for several design variants is a time-consuming process.
In addition, current tire simulation models cannot always reproduce such behavior and they usually rely on costly parameter identification processes
