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 |
| • | User defined road models |
| • | Third party generally available road models (e.g. the CRG format) |
The most important of these road models are documented in detail in the following sections:
Road Profiles and Obstacles in COSIN/io Format
Road Profiles and Obstacles in TeimOrbit Format
COSIN Road Track Files
User-Defined Road Models
| 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.
