Virtual Test Drive (VTD) is our toolkit for the creation, configuration, presentation and evaluation of virtual environments in the scope of road and rail based simulations. It is used for the development of ADAS and automated driving systems as well as the core for training simulators. It covers the full range from the generation of 3d content to the simulation of complex traffic scenarios and, finally, to the simulation of either simplified or physically driven sensors. It is used in SiL, DiL, ViL and HiL applications and may also be operated as co-simulations including 3rd party or custom packages. By its open and modular design it can easily be interfaced and integrated.
General:
- Build Systems and Compilers: We’ve upgraded our build systems and compilers. These changes might not be immediately noticeable to users but are essential for significant improvements in future releases.
- Startup Issue: The startup issue with RockyLinux 9.3 has been resolved.
- Release Schedule: There will be no VTD 2024.4 release in December. The next release, VTD 2025.1, is planned for March 2025.
Installer Improvements:
- Base Packages: Installation directories for base packages like FULLSTACK, SIMULATE, and CREATE can now be set without creating a subfolder in VTD, improving clarity on where installation content is located.
- Add-on Packages: Installation directories for addon packages, such as tile packages, can now be set directly to the directory containing the VTD installation. No need to choose the parent folder of the VTD installation.
TaskControl:
- SCP Flag Override: When the SCP flag override for <Set><RelativePos> is true, TaskControl will override the simulation state to prevent jitter between traffic and external objects.
Scenario Editor:
- Object Scaling: Scaling of dynamic objects in the Scenario Editor is now possible during runtime. Users can now scale players or objects in both the Image Generator and the Scenario Editor while the simulation is running.
Complex Dynamics:
- Powertrain Model:
- Re-implemented the powertrain model.
- Added engine braking effect for low throttle values.
- Corrected the torque-throttle relation.
- Throttle Estimation:
- Fixed the throttle estimation bug. Vehicles can now use target acceleration when using Complex Dynamics.
- Considered road slope when evaluating throttle.
- Vehicle Repositioning: Eliminated unwanted vehicle repositioning.
- Neutral Gear: Vehicles can now roll down slopes when in neutral gear.
- Ego Vehicle Behavior: Harmonized the behavior of the ego vehicle between simple and complex dynamics.
ImageGenerator:
- Shader Output: Fixed the shader output of the sawtooth function.
RDBSniffer:
- CSV Misalignment: Fixed the misalignment issue in the CSV for the package RDB_OBJECT_STATE_t in RDBSniffer. For extended properties, the static object value is now set to ‘NA’.
SurfaceAnalyzer:
- Crash Fix: Resolved the crash issue on Ubuntu 20.04.
RoboSenseM1:
- New IG Plugin: Introduced a new IG plugin with Setup, Project, and running Scenario.
- Documentation: RoboSenseM1 Documentation .
