The 2024.2 versions contain a number of improvements which are detailed in their release notes. The following notable changes are included in this release:
- VeSyMA – Driver-in-the-Loop
- Now supports rFpro 2024a.2.
- The initialisationValues class has been improved to include the features of the TerrainServer.TerrainServerInterface.Components.InitialRoadValues class. The initialisationValues component is used to set the initial location of the vehicle. This modification allows the vehicle to be started along the driving line or at a location specified by AIW coordinates as well as at a specified location and orientation as was previously supported. By default, when the vehicle is exported using exportModel the vehicle should start at the location specified by rFpro unless UseDefaultInitialisationValues is true. If UseDefaultInitialisationValues is true then the location specified in initialisationValues will be used.
- VeSyMA – Terrain Server
- Now supports rFpro Terrain Server 2024a.1 and the rFpro Terrain Server 2024a.1 API.
- FluidPower
- Improvements of the accumulator models to have more realistic thermodynamic behaviour and improved initialisation to allow them to contain oil at the start.
- VeSyMA – Suspensions
- Removed Simcenter Tyre resource files for Linux 32-bit as for Dymola 2025x support for 32-bit simulation in Linux has been discontinued.
- VehicleDemos
- In the Dymola 2025x installation, the Thermal Systems libraries have been replaced with the TIL Suite libraries. Due to this, from this version of the VehicleDemos library we have changed from using classes from ThermalSystems to TIL, TSMobileAC.Cabins to TIL3_AddOn_Cabin and TSMedia to TILMedia.
