Double Lane Change Simulation

Hello,

I'm trying to run a double lane change simulation using the custom full vehicle assembly. Once I run the simulation, the vehicle seem to have difficulty following the desired path. I've tried both "default" and "max radius path" controller type, both not able to follow the path correctly.

Is there a feature that I might have missed that I need to control in order to keep the vehicle on the right track?

Any help would be much appreciated.

Thanks

Have you made sure that the steering is hooked up properly? A positive steering wheel displacement should turn the steering wheel to the lest and the wheels should turn left as well. This is one of the most common errors for the steering controller to malfunction. Does the open loop maneuvers work as expected? Ramp steer is always a good open to start with. A ramp of +20 deg/s should be useful to see that the SW really goes to the left and the vehicle turns to the left. Will also tell you if the steering ratio is proper.

On that note: Calculate the overall steering ratio from front suspension assembly steering test. Make sure that the .assembly.testrig.pvs_steering_ratio is set to the proper value for the full vehicle. Otherwise the controller will not work properly.

If all this is done properly, you have to start working with the controller parameters for the event. But if you are running a passenger car, the default controller parameters are usually good enough.
