1. Introduction
This guide is intended to help introduce you to CarSim. You should have CarSim installed on
your computer, but no experience with using the software is assumed. If you do have some
experience with CarSim, it might still be a good idea to go through this guide. It typically takes
less than an hour and most people learn something even if they have already used CarSim.
Computer Requirements
CarSim runs on Intel PC’s (or equivalent) equipped with Windows 2000, XP, and Vista. It is self-
contained, requiring no additional programs or tools to run.
Note CarSim math models can be extended using MATLAB
®
Simulink
®
(from
The Math Works, Inc.) and other simulation tools. This introductory
guide does not cover the topic of extending CarSim models.
Here are some general guidelines when considering computer hardware options:
• Speed: Get a fast CPU. It is not essential to have the fastest available, but the vehicle
models are computationally intensive and you will save time with a fast CPU. The
amount of level-2 cache is also important.
• Graphics: Get a graphics card that supports OpenGL 2.0 hardware acceleration, with
at least 64 MB of video memory.
• Storage: The vehicle simulation packages require about 500 MB of disk storage.
With extensive use, you will need about 1 GB. Most modern PC’s have plenty of
storage relative to these needs.
Notation Conventions in This Guide
The bulk of this guide is presented using a Times font. Other fonts and styles are used to convey
special meanings.
• The Courier font is used for names of computer files and folders.
• Bold identifies items on the screen that you might click on—buttons, menu items,
names of linked datasets, etc. Titles of screens are also shown in bold.
•
Underline is used to indicate text that you might type. For example, “In the speed
field, type
160.”

What Is Covered In This Guide
Chapter 2 provides a short overview of how CarSim works
Chapter 3 provides step-by-step instructions that will take you about an hour to complete. You
will learn how to interact with the CarSim Animator and make plots of variables calculated by the
CarSim math models. You will navigate the CarSim database and make some new runs. You will
perform a “what if” exercise by taking a few minutes to define a new vehicle with a different
center of gravity. You will run the new vehicle and see how its behavior compares with the
original.
In Chapter 4, you will get some hints for using more CarSim features, including navigation and
on-line help. You will see more about plotting, and will see how to use the animator outside of
CarSim for presentations or interactive use by colleagues who might not have CarSim. You will
also be introduced to the methods used to transfer data between different CarSim databases.

2. How CarSim Works
CarSim shows how vehicles respond dynamically to inputs from the driver and the immediate
environment (road and wind). It produces the same kinds of outputs that might be measured with
physical tests involving instrumented vehicles.
Parts of CarSim
CarSim is composed primarily of four tightly integrated software modules, shown schematically
in Figure 1.
