Abstract

The tyre forces computation module, DTIRE, has been developed in the R&D department of Steyr-Daimler-Puch Fahrzeugtechnik supported by an extensive testing and measurement programme. The major goals of DTIRE were identified as: (1) tyre forces generator for vehicle dynamics simulation; and (2) an observer model for real time processing for the development and production of all-wheel-drive vehicles and system components. The codes themselves are written in FORTRAN 77 and currently they are linked to the multibody simulation system DADS. However, in principle the tyre processor works autonomously. The semi-empirical model is based on the "Magic Formula" approximation technique for the description of tyre forces and torques. One necessary extension concerns asymmetrical force-slip characteristics, as they are typical for tyres of direction oriented type. A simplified interpolation approach is taken, in order to perform computations efficiently. Some selected examples are presented briefly.
