CarSim Model and License Options
This document summarizes model and license options for CarSim 2024.0. Unless otherwise noted,
all optional features are supported on all operating systems and in combination with all otherfeatures.

CarSim for Windows
The basic CarSim installer provides a database and browser with a user interface, visualizer(plotting and animation), math model solver libraries, extensive documentation, and many example
vehicles, procedures, and simulations. Two versions of the browser, math model libraries,
visualizer, and other tools are provided to work with 32-bit and 64-bit environments.
The CarSim math models support a four-wheeled motor vehicle with or without a trailer (with one,two, or three axles), using any combination of independent and solid-axle suspensions, possibly atwist-beam rear suspension, and possibly an independent steered front suspension with a virtual
kingpin on the motor vehicle. The model works as-is and can optionally be extended with the builtin scripting language (VS Commands), embedded Python, Simulink, and LabVIEW. The mathmodel can also be extended using external programs written in MATLAB, Visual Basic, C/C++,
Python, and other languages that can interact with Windows DLLs. Up to 200 built-in moving
objects can be controlled to simulate traffic and safety-related scenarios.
The 32-bit and 64-bit versions of the CarSim math models run at the same speed, with the two
versions being provided to support compatibility with third-party software. When CarSim is usedalone, there is a choice between 32- and 64-bit browsers (CarSim.exe and CarSim_64.exe);
when used with third-party software (e.g., 64-bit Simulink), the appropriate solver plugin librarymust be used.
The basic CarSim for Windows package includes two licenses:
1. The CarSim Solver for Windows License is needed to make a new simulation run with amath model.
2. The CarSim Browser and Graphical User Interface License is needed to run the main GUI,
manage the database, control runs, view animations, etc.
It is rare for one of the basic licenses to be provided alone; both are needed for normal operation of
the software, and both are provided as part of the basic package. (The option for obtaining just one
Solver license is to support custom automation capabilities for sites with many CarSiminstallations.)
The CarSim Solver for Windows License supports all CarSim vehicle configurations based on asingle vehicle unit (no trailer) with a rigid sprung mass (no frame torsional flexibility).

CarSim for Linux
CarSim for Linux is identical to CarSim for Windows with two major differences; it does notinclude the CarSim browser, and the math model is 64-bit only.
CarSim for Linux includes a database, visualizer (plotting and animation), math model solver
library, extensive documentation, and many example vehicles, procedures, and simulations.
CarSim for Linux is mostly used for automation for sites with many CarSim installations.

ADAS Sensors
The optional CarSim Sensor License allows activation of up to 99 built-in range and tracking
sensors to sense moving objects (up to 200). Calculated sensor detection variables can be sent toexternal controller models in Simulink, LabVIEW, or other environments.

Multiple Vehicles
The optional CarSim Multiple Vehicle License allows up to 3 additional lead unit vehicles to beused in a single solver instance. The option to configure multiple vehicles is supported via theCarSim Browser.

Trailer
The optional CarSim Trailer License allows use of a trailer with one, two, or three axles. If themultiple vehicle license is used, trailers may be added for all the vehicles in the simulation.

Engine Mount
The optional CarSim Engine Mount License allows the use of vehicle models with an engine andtorque rod with additional degrees of freedom (DOF). These are modeled as six mounts: four forthe engine and two for the torque rod.
The Engine Mount feature cannot be used at the same time as the Frame Twist model feature.

Frame Twist
The optional CarSim Frame Twist License allows use of models with frame twist DOF that
represent the distribution of torsional compliance along the length of the Sprung Mass body andtherefore affect the load transfer to the tires. When enabled, the Frame Twist option affects themotor vehicle and a trailer, if linked.
The Frame Twist feature cannot be used at the same time as the Engine Mount feature.

Third-Party Tire Models (Siemens, COSIN, and Michelin Tires)
The CarSim Windows installation includes interfaces for tire models from Siemens (MF-Tyre/MFSwift), COSIN (FTire) and Michelin (TameTire). Example datasets are included for each of thesetire model options. The four license options are:
1. Siemens MF-Tyre v2212 natively connected with CarSim runs under any CarSim license
together with all options except the Enveloping contact, Rigid-ring, Turnslip andTemperature Model options that run under Windows and Linux OS.

2. Siemens MF-Tyre v2212 connected with CarSim on Simulink requires an optional paid
license from Siemens in addition to a basic CarSim license that runs under Windows OS.
3. Siemens MF-Swift v2212 (including Enveloping contact, Rigid-ring, Turnslip, andTemperature Model option) requires an optional paid license from Siemens in addition
to a basic CarSim license. With this license the MF-Tyre/MF-Swift model will work
together with all options that run under Windows and Linux OS.
4. COSIN FTire requires an optional paid license from COSIN in addition to a basic CarSimlicense. With this license the FTire model will work together with all options that run underWindows OS. Any version older than FTire 2021-3 is not supported.
5. Michelin TameTire requires an optional paid license from Michelin in addition to a basic
CarSim license. With this license the TameTire model will work together with all options
that run under Windows OS.
These external tire models support 32-bit and 64-bit versions of their respective solvers.
Siemens MF-Tyre/MF-Swift v2212 is also available for real-time (RT) use on dSPACE DS1006,
SCALEXIO and Concurrent RT. The RT versions require a paid license from Siemens.
NoteAs MF-Tyre/MF-Swift v2212 has technical issue on SCALEXIO/QNX
running with CarSim, only v2022.1.1 is supported.

CarSim currently supports COSIN FTire model in standard operation mode on Windows.
Accelerated FTire/HIL execution mode is currently being considered for future interface extension.

Parallel SolverThis optional counted license allows additional process instances to simultaneously run CarSim
simulations on the targeted machine (process-level parallelism). This is useful for simulations
involving multiple vehicle interactions orchestrated by external software such as MATLAB /Simulink, or for custom server deployments of CarSim expected to be running many CarSimsimulations.

HPC Licenses
Like the Parallel Solver license, the HPC license is an optional counted license allowing additional
process instances to simultaneously run CarSim simulations on a targeted machine (process-levelparallelism). Where the HPC license differs is how license deployment is organized and deployed.
The HPC license scales to many thousands of parallel instances. The Parallel Solver license does
not support this level of scalability. HPC Licensing is best suited for large scale deployments whereno single external simulation master is in control and when many thousands of simultaneous
simulations are needed.

CarSim Real TimeRT Platforms
The CarSim installer for Windows includes support for eight RT platforms:
1. dSPACE DS1006/DS6001 and SCALEXIO
2. National Instruments LabVIEW RT/VeriStand (ETS OS and Linux RT OS)
3. ETAS LabCar RTPC
4. Opal RT-LAB (QNX RT OS and Linux RT OS)
5. Concurrent Real Time System
6. A&D Technology
7. MathWorks Speedgoat
8. Vector CANoe
An optional CarSim RT license is needed to run on any of these RT systems. The same set of
optional licensed features that are available for the CarSim Windows installation are also available
for CarSim RT: ADAS Sensors, Trailers, Engine Mounts, and Frame Twist.
The CarSim RT solvers do not work with the external component models from COSIN or AVL,
with the exception that Siemens tire models are available for dSPACE DS1006/SCALEXIO andConcurrent RT.

Extra Live Animations
CarSim RT supports a live animation license that supports a single connection between the mathmodel and VS Visualizer, which in turn supports up to three monitors. If more connected computers
running VS Visualizer are needed, additional live animation licenses can be purchased for allsystems except dSPACE.

Windows DS for CarSim
The optional CarSim DS License is available to support a Windows-based desktop driving
simulator. Driving hardware is either a Logitech G29 or G920 steering wheel, shifter, and pedal
set. Although no longer produced by Logitech, Mechanical Simulation maintains legacy supportfor the G27.
The DS example datasets include software to support a single live connection between a vehicle
math model and the VS Visualizer, which in turn supports up to three monitors. Additional live
animation licenses can be purchased if more connected computers are needed to run more VS
Visualizer instances.
