        To specify and evaluate road excitation, COSIN/road uses one central subroutine evrmr (COSIN environmental models: road main routine).
        Road Profiles and Obstacles in COSIN/io Format
        If COSIN/road detects the road file in COSIN/io format, it first tries to read certain information common to all road types within this format (see Data Common to all COSIN/io Style Road Types).
        Road Profiles and Obstacles in TeimOrbit Format
        If COSIN/road recognizes the road data file is in TeimOrbit format (typically, the file name extension is rdf), it branches into the respective reading and evaluation routines.
        COSIN Road Track Files
        If the road data file is in COSIN/io format, but does not contain the data block $road_type, it is interpreted as a COSIN road track file.

COSIN FTire Documentation

To specify and evaluate road excitation, COSIN/road uses one central subroutine evrmr (COSIN environmental models: road main routine).

This routine, for example, is called by the CTI tire interface to 3rd party simulation software, by COSIN/mbs and by FTire/sim, receives during initialization the name of the road data file by the calling program. On the basis of the file name and the file contents, evrmr determines the data file format. Accordingly, it branches into one of several evaluation routines. Among these are routines for the following:

COSIN/io style 2D and 3D deterministic, stochastic, or measured obstacles/profiles
TeimOrbit™ style 2D and 3D deterministic, stochastic, or measured obstacles/profiles
RGR regular grid road models
COSIN road track files
User defined road models
Third party generally available road models (e.g. the CRG format)

Note: Not all the road models are available in all simulation environments which use COSIN/road. On the other hand, COSIN/road may be able to call additional, proprietary road models of the calling software.

Please refer to the respective original documentation to learn more about the availability of road models in your simulation environment, or contact info@ftire.com for more information.

The most important of these road models are documented in detail in the following sections:
