How to simulate the Slalom maneuver in A/Car

Hello
I want to simulate the Slalom maneuver (which means driving between the cones located with equal interval).
First, I tried to set up the Sine-Sweep Steer according to Slalom characteristics. I mean, to find correct values of steer frequency and steering angle to ensure model riding with proper lateral displacement (which more than a half of car width, obviously). But the path of the model (when you check it in a postprocessor) doesn't look like as desired to be (in a picture attached). There is an explanation for this issue, I know
So, Sine-Swept Steer maneuver doesn't meet the requirements.
I remember that one day I found a picture of the FVA staying on a road with cones (for slalom maneuver, I suppose). So, there must be a tool to build this road. But I didn't find anything looks like a cone in Obstacles menu in Road Builder.
If you know how to simulate the slalom maneuver, please, tell me about it.
Thank you in advance.

  • Hi Viktor,
     
    1. Sine-Sweep event should have served the purpose. But, from the picture you posted it seems like your vehicle is drifting. May I know whether the model was built by you or is the Model from   ADAMS Shared database? Use the shared database model, and simulate the sine-swept steer event and compare the results.
    2. Another solution is to build a road using road builder with the desired path as center line to the road. (*.rdf). Then you can use course event option for simulations.
    3. The third solution is defining path using event builder option in the car.
     
    Regarding Cone in obstacles in road builder, I have not seen such an option in road builder. May be the cones were CAD files imported for animation purpose.
     
    Hope this helps.
     
    Regards
