12. Tutorial EDSVS TUTORIAL Chapter This tutorial comes from the EDC Simulations seminar It provides a good example of the use of the driver input tables In particular it illustrates how the driver tables use linear interpolation to compute the current steer angle The goal of this tutorial is simply to make the simulated vehicle follow the desired path Only steering is required so the scope is limited but extremely useful Like all EDSVS events the procedures involve the following basic steps l lt a fe Create the vehicles Create the environment Execute the EDSVS event e Review the EDSVS output reports These basic procedures are described in detail in this tutorial Rp NOTE It is assumed that HVE 2D is up and running and that the user is familiar with HVE 2D s basic features such as using HVE 2D s dialogs and viewers as well as the HVE 2D Editors The purpose of this tutorial is to illustrate those features while setting up and executing an EDSVS event EDSVS Getting Started Getting Started As inother tutorials before we get started with our current tutorial let s set the user options so we re all starting on the same page IS NOTE In HVE 2D all options simply affect the appearance in a viewer during Event or Playback mode IS However in HVE AutoPosition affects the data used in the analysis For example if AutoPosition is On the vehicle position conforms to the
