Creating Custom Vehicle Event

sudo

Would it be possible to create a custom vehicle event wherein it contains different types of tracks in just one event. For example it will start in flat roads, then there will be uphill and downhill, then rough roads, steep curves, etc?

Thanks!

Hi @sudo,

Yes, a custom duty cycle can be easily implemented using the Road Course event and a 3D spline road file.

After adding the Road Course event, you can specify that the vehicle follow the road centerline. Now any road file you define the vehicle will attempt to stay centered throughout the run.

The 3D Spline road type allows you to define multiple Obstacles throughout so you can achieve one duty cycle. In the installation directory, you can find a good example of this with the 3D_Spline_St_Obs.RDF file.

Hope this helps!

Hey @GTT Adam Thanks for your response.

I tried to use the 3D_Spline_St_Obs.rdf file from the examples, but I am always having this error when creating the road. This error shows after clicking the 'ok' button in the road tools panel.

The motionsolve is not responding and is stuck in the loading the graphic.

Also I checked the code of the rdf file and I noticed that all of the obstacles start at 0 even though the obstacles are far apart from each other. Why is that?

Hi @sudo,

It looks like there is a bug in the Road Tools Utility for visualizing specific road types.
1. For now, please use version 2023.1 and export the graphic as a MDL definition then import into your 2025.0 model.
2. This only effects the road graphic, and not the actual performance of the tire model interacting with the road, so there is no issue when generating the actual results.
The obstacle definitions in the RDF do not dictate their starting position. That is done when you place the Obstacle keyword under the [DATA POINTS] header. The START keyword from the each [OBSTACLE] heading is a relative offset from that point.

Hope this helps!
