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

TruckSim for Windows
The basic TruckSim installer provides a database and browser with a user interface, plotter,animator, both 32-bit and 64-bit math model solver programs, extensive documentation, andmany 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 TruckSim math model supports single-unit and combination vehicles. The TruckSim GUI
supports a lead motor vehicle unit with up to five axles, semitrailers with up to four axles, anddollies with up to three axles. Suspensions can be generic/independent or solid axle. Advanced
users can simulate more complex vehicles by using generic GUI screens: TruckSim supports up
to 64 units, each with any number of axles in groups of 1, 2 (tandems), or 3 (tridems). The
maximum number of axles allowed on a vehicle is 128.
The model works as-is and can optionally be extended with the built-in scripting language (VSCommands), embedded Python, Simulink, and LabVIEW. The math model 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 tosimulate traffic and safety-related scenarios.
The 32-bit and 64-bit versions of the TruckSim math models run at the same speed, with the twoversions being provided to support compatibility with third-party software. When TruckSim isused alone, there is a choice between 32- and 64-bit browsers (TruckSim.exe andTruckSim_64.exe); when used with third-party 64-bit software (e.g., 64-bit Simulink), theappropriate solver plugin library must be used.
The basic TruckSim for Windows package includes two licenses:
1. The TruckSim Solver for Windows License is needed to make a new simulation run witha math model.
2. The TruckSim 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 operationof the software, and both are provided as part of the basic package. (The option for obtaining justone Solver license is to support custom automation capabilities for sites with many TruckSim
installations.)

The TruckSim Solver for Windows License supports all TruckSim vehicle configurations basedon rigid sprung masses (no frame torsional flexibility).

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

ADAS Sensors
The optional TruckSim 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 TruckSim Multiple Vehicle License allows up to 3 additional lead unit vehicles tobe used in a single solver instance. The option to configure multiple vehicles is supported via theTruckSim Browser.

Frame Twist and Suspended Cab
The optional TruckSim Frame Twist License allows use of models with frame twist degrees offreedom (DOF) that represent the distribution of torsional compliance along the length of theSprung Mass body and therefore affect the load transfer to the tires. When enabled, the Frame
Twist option affects the motor vehicle and a trailer, if linked.
The lead unit with frame twist also has a suspended cab with three additional DOF.

Third-Party Tire Models (Siemens and COSIN)The TruckSim Windows installation includes interfaces for tire models from Siemens (MFTyre/MF-Swift) and COSIN (FTire). Example datasets are included for each of these tire modeloptions. The three license options are:
1. Siemens MF-Tyre v2212 natively connected with TruckSim runs under any TruckSim
license together with all options -except the Enveloping contact, Rigid-ring, Turnslip,and Temperature Model options that run under Windows and Linux OS.
2. Siemens MF-Tyre v2212 connected with TruckSim on Simulink requires an optional paid
license from Siemens in addition to a basic TruckSim license that runs under WindowsOS.
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 TruckSim 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
TruckSim license. With this license the FTire model will work together with all options
that run under Windows OS. Any version older than FTire 2021-3 is not supported.
These external tire models support 32-bit and 64-bit versions of their respective solvers.

Parallel SolverThis optional counted license allows additional process instances to simultaneously run TruckSimsimulations 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 TruckSim expected to be running many TruckSimsimulations.

HPC Licenses
Like the Parallel Solver license, the HPC license is an optional counted license allowing
additional process instances to simultaneously run TruckSim simulations on a targeted machine(process-level parallelism). Where the HPC license differs is how license deployment isorganized and deployed. The HPC license scales to many thousands of parallel instances. TheParallel Solver license does not support this level of scalability. HPC Licensing is best suited forlarge scale deployments where no single external simulation master is in control and when many
thousands of simultaneous simulations are needed.

TruckSim Real TimeRT Platforms
The TruckSim 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 TruckSim RT license is needed to run on any of these RT systems. The same set of
optional licensed features that are available for the TruckSim Windows installation are alsoavailable for TruckSim RT: ADAS Sensors and Frame Twist with Suspended Cab.
The TruckSim RT solvers do not work with the external component models from Siemens,
COSIN, or AVL.

Extra Live Animations
TruckSim RT supports a live animation license that supports a single connection between themath model and VS Visualizer, which in turn supports up to three monitors. If more connectedcomputers running VS Visualizer are needed, additional live animation licenses can be purchased
for all systems except dSPACE.

Windows DS for TruckSim
The optional TruckSim 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 support
for 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.
