Tyres are a crucial component of the chassis and considerably influence the vehicle dynamics. To engineer for optimal vehicle performance, vehicle OEMs, chassis and vehicle integration departments are required to adapt tyre models to a broader range of operating conditions, balance performances and speed up the time-to-market.
Tyre performance is known to be highly dependent on the tyre thermal state and its forward velocity. Important passenger car tyre characteristics as the cornering stiffness and peak friction may vary up to as much as 20% as a function of Temperature &Velocity throughout their normal operating window.
With the introduction of the Temperature & Velocity model extension to its Pacejka’s Magic Formula based Simcenter Tyre products, Siemens offers Vehicle Dynamics engineers, Tyre testing and modelling experts the possibility to explicitly model the effects of temperature and velocity on the tyre performance. This further increases applicability and accuracy of the tyre model in vehicle simulations ranging from handling to durability.

Modelling tyre performance requires a lot of expertise and specialization. For this purpose, Simcenter offers engineers scalable and customized solutions through an end-to-end tyre modelling method that provides high accuracy, efficiency and tool standardization.
Tyre performance is known to be highly dependent on the tyre thermal state and its forward velocity. In order to describe the impact of these effects on the vehicle dynamics, Siemens presented a scientific paper at the 2020 SAE World Congress: “A Study on the Effect of Tyre Temperature and Rolling Speed on the Vehicle Handling Response”.
This webinar outlines the vehicle dynamics simulation requirements in the context of autonomous driving.
