Mechanical Simulation Releases TruckSim 8.1.



by James Hilton

Mechanical Simulation is proud to announce the December release of TruckSim 8.1, which features improvements for both new and existing users.

The most visible improvement to TruckSim comes from a new program called the VehicleSim (VS) Visualizer. VS Visualizer makes use of modern graphical processing units (GPU) and shape file formats. It provides advanced lighting (true shadows, multiple light sources, reflected highlights), highly efficient rendering, rear-view mirrors, and advanced techniques taken from video game technology. VS Visualizer provides support for new advanced driving simulators, but provides incredible visualization for all TruckSim users.
The new TruckSim release includes some major new options in the vehicle math models:

• Driver Model Improvements. TruckSim now supports a driver reference path that is separate from the road reference line, in support of simulations with arbitrary target paths. A path preview option is included in the speed controller to define speed as a function of curvature, aggressiveness (lateral and longitudinal acceleration limits) and skill level. The controller also has an option to take 3D surface properties into account (bank angle, grade angle, curvature normal to the road surface).
• 64-bit support for TNO and COSIN FTire tire models. Support has been added for 64-bit versions of TNO and COSIN tire models, allowing them to be used with TruckSim when running with other 64-bit software (e.g., 64-bit Simulink).
• Extension to the built-in tire models. Another parameter is available in the built-in tire model to control the transition between longitudinal and lateral slip in combined slip. This can improve realism for some datasets.
• Continuously Variable Transmission (CVT). The TruckSim powertrain now includes an option for CVT, with corresponding improvements in the GUI and documentation.
• Miscellaneous Improvements. More improvements have been made to configurable table functions, including a new _EQUATION option and extensive support from the VS API. More outputs have been added to support a road-based axis system to define pitch and roll relative to a design surface. Minor changes have been made to simplify navigation in the GUI.

“TruckSim 8.1 improves on some of the capabilities added in recent years, while also introducing new features that our customers have been asking for,” said Michael Sayers, CEO and chief technology officer at Mechanical Simulation. “The VehicleSim Visualizer takes advantage of new computer capabilities for visualization and animation, and gives all TruckSim users the same state of the art as those running advanced driving simulators. Other improvements extend the capabilities of TruckSim already in use for simulating advanced procedures used throughout the world to evaluate heavy truck and bus performance.”
