![]() ![]() Once again, a very long time after my last post here, but, as I mentioned last time, with this article I would like to discuss something I find very interesting and that could be useful for all the people involved with vehicle modeling and, in particular, with tire modeling.Īs discussed in my previous article, one of the first steps whenever working on a vehicle model is to check/validate/build a tire model that ensures a reasonable and realistic performance envelope for your virtual car. If this is in my humble opinion absolutely necessary for every kind of vehicle dynamics simulation (because of the very strong influence that tires have on car performance and behavior), it is even a more important step for a driving simulation, where the tire model is not only directly and strongly influencing model’s performance, balance and behavior but also driver feeling and, as a consequence, how useful the complete simulation process is: if the driver “feels” the car is behaving closely to the real one, he will (hopefully) drive the model in a similar way to how he would drive the real vehicle, producing as a consequence more realistic and useful results.Īs we have already seen, unfortunately tire data are sometimes unavailable and, in any case, need to be carefully checked and validated to avoid building up a car model with a totally unrealistic performance envelope, compared to the real counterpart.īut what to do if you don’t have accurate tire data or if you need to double check what you have? ![]()
