How to make the vehicle follow a curved road

Sreedhar Bollishetty_21390

Hi,

I have a curved road profile, now i want to run the vehicle on this curved road following the road profile.

Basically i need to steer the vehicle to follow the road profile.

Is there any event, in which road profile is considered and steer the vehicle along this profile

Hi Sreedhar,

Please try a road course drive event. In the dialog of road course event,

• use "Road Centreline" in path profile. Driver will automatically extract the centre line of road and will use it as a steer line
• In the Road Parameters, select 'Road File' from Road Selection drop down. Provide the path to your road file
• Run the event

Yes, i have already tired using the road center line and the curved option also.

for road center line i am getting below error ( Using CRGE road in  Auto tires)

 

For Curved option i see the error related to the Spline as road is curved ( going from +X to -x)

Hi Sreedhar,

I downloaded this road file and checked the csv file that comes along with it. This csv file contains the road centerline and has x data in increasing order

In your message, the x data seems to carry negative sign. Please cross check it once.

 

Also send me your email id so that I can schedule a call.

Yes..i have multiplied by -1

But, this is not the issue. Even you see the issue if you use the above values shown by you.
