VI-grade, a simulation and driving simulator company, has announced the 2021.3 release of its software product suite. The release includes product updates and several usability enhancements for VI-CarRealTime and VI-WorldSim, as well as the VI-DriveSim driving simulator platform.
The 2021.3 release of the VI-CarRealTime real-time vehicle simulation environment, features an alternative modelling approach, with templates for typical suspension architectures in addition to the traditional curve-based modelling approach. This approach enables a direct hardpoint and bushing based parametrisation within the VI-CarRealTime user interface, highlighting the built-in Investigation Mode to set up DOEs.
Additional new features include advanced obfuscation with vehicle parameters override files, which facilitates collaboration between partners and suppliers; an updated model conversion process from Adams Car to VI-CarRealTime; and multiple runtime selectable EPS maps.
The VI-WorldSim graphic environment focuses on ADAS development, and is now available with offline analysis capabilities. This enhancement enables users to run VI-WorldSim independently from VI-DriveSim, so they can focus on offline experiments. Offline usage is enabled through a direct Simulink integration with sensor data compatibility with standard Mathworks toolboxes and a seamless integration with VI-CarRealTime offline plant models. Put simply, users can first develop ADAS algorithms entirely on their desktop PC and then use the online version of the software to validate their functionality with the driving simulator.
Additional new features in the latest VI-WorldSim release include improved processes for importing user-defined road environments based on Roadrunner (Mathworks’ interactive 3D editor), multiple new public road and race track environments including Wolfsburg, Calabogie, Hockenheim and more.
The 2021.3 update also includes enhancements for VI-DriveSim, a software platform for controlling driving simulator components. The 2021.3 release introduces unified firmware for active braking and steering, integrated support for cable-driven simulators (DiM400 and above) and actuator-based simulators (DiM150 and DiM250) in the same build.
