Is there an existing method for integrating mapped terrain data within ADAMS CAR?

Hello,

I was wondering, is there an existing method currently available or under construction within ADAMS/CAR that allows the user to integrate mapped terrain data as a road or similar? I am working to merge gaps within a vehicle autonomy project in which the current terrain data is gathered and mapped within Unreal Engine. I am aware that there is support for graphical and data integration within CarSim, and I was wondering if the same was possible within ADAMS in some form. In my case, the support of the graphical renderings aren't my key concern, although useful, my primary objective is the ability to integrate mapped terrain data created from LIDAR/RADAR etc. into an ADAMS/CAR simulation.

Thanks for any info,

Cheers!

As far as I remember that's what Vires VTD can do and it's part of Hexagon/MSC by now.

Virtual Test Drive, or VTD as Martin mentioned above is our solution for testing, validation... of ADAS functions and Autonomous Vehicles https://vires.mscsoftware.com/

You can definitely export an ACAR FMU model into VTD to develop the available LiDAR/RADAR... models or develop your own one.

Please get hold of the local Hexagon.MSC representative to provide you an overview of the software, the Hexagon synergies...

There is also a workflow for taking scanned road data, and turning it into a RDF file for use in durability simulations with ADAMS/Tire, etc. It's more of a process though than a canned solution. So, Alexis' recommendation still applies: contact your local Hexagon.MSC representative. It comes down to your specific needs/requirements.

I always wanted VTD but unfortunate it is not part of MSC One.

What I was using is exporting acar model as fmu. You can control steering, braking, throttle, gear, clutch signals as fmu inputs using varvals, mdi_sdi_testrig contains many outputs for fmu outputs. Using this fmu model in Simulink gives you all possibilities of Matlab Simulink, using Unreal, and for Road network also RoadRunner

I am not sure if RoadRunner is always part of Matlab, we just contacted Mathwork representative and added it to our Mathworks account

Hi Josef,

Yes you are right, VTD is not part of MSCOne, however there is a University Research Deal

Hi @Alexis, I do not know and never heard about this. I know just about MSCOne, and University Motion Bundle. We have these two solutions. Where can I find more info about this Univesity Research Deal? My university mail is jozef.bucha@stuba.sk

Thanks,

Jozef

Hi @jozef.bucha, I have just sent an email to the 'Slovenská technická univerzita v Bratislave' Account Manager, she will be in touch with you to discuss VTD.

Hello,

I am wondering, is there a possible method of co-simulating between Adams and Unreal Engine? The reason I ask is that I need to feed the vehicle terrain data which we have already mapped in Unreal so unfortunately, using VTD will not be an acceptable solution for me. I think I could possibly accomplish this by exporting the vehicle model as an FMU and use a plugin within unreal to translate data between the two softwares. This idea is stuck with two significant concerns:

The only Unreal Engine FMU plugin I believe currently exists supports only float and boolean variable data (0/1) and I am not sure the variable data type of the Adams FMU export

The FMU export option relies on the use of an event file (driver/road data), which I am looking to feed using the Unreal Engine. (I only wish to use Adams as a solver for the mechanical systems of my vehicle which will be driven by an autonomous controller built in Unreal)

To clarify, I am not asking if there is a way to do all of this, I am instead asking if it is even theoretically possible by the methods I have suggested above, or some alternate method.

Yes, it is possible to co-simulate with Unreal. If you look at the different export options in Adams/Car (after you load the Controls plugin) you'll see that there are multiple variants of export. Both the real-time option (intended for driving simulators) and the VTD export of course assumes that driver commands are coming from the co-simulation. And I believe that even the general FMU export has the possibility to add driver commands to the input channels (but that needs to be verified).
