The present paper is a summary of the validation work conducted as part of an SUV suspension development for local market. An extensive use of Vehicle Dynamics Simulation was done during this vehicle development, and the SUV model validation was decided on two traditional handling maneuvers, one to evaluate the transient behavior (ISO 3888 Chicane) and the other for the steady state condition (constant radius curve).
A prototype was instrumented and all related data was collected at Pirelli Brazil Test Track facilities. Those data were then introduced in the simulation software, in its validation mode, in order to run a simulation at exactly the same input conditions as the real tests. Such simulation results were afterwards compared with the real data and the required adjustments were done in the simulation model.
The real vehicle handling data showed a very satisfactory correlation with the simulation model, with adequate precision for development requirements.
