- New Instruction Video Created and new project will be included in the update Path Follower template
- New! 2021 Mar: Path Follower Instructional video Full video 21:02 run time (also link video link below)
- Set Video quality to HD!! BE SURE to set Youtube to HD (your playback may default to 480...blurry!)
- To Get the project created in the video:
- Download the Path Follower Template ZIP file(80 megs)
- Save to your computer,
- Use the Restore Project function from 3D Graphics to restore the project,
- Then view the various option outlined below and work along with the online videos

Time on Video | Link to place in Video on Topic |
---|---|
@1:00 | Clone the project |
@2:06 | Inputs for Path follower on inputs 402,403,404,405 |
@2:34 | Turn off the collision simulation to allow easy setup of impact configurations |
@3:38 | Settings Dialog Options including: |
------> turning On/Off the path to be followed by the path follower mode | |
@4:37 | Run 0 sec simulations to set up path discussion and discussion of inputs for path |
@4:36 | ------> Set path follower to vehicle initial position |
@5:19 | ------> Setting up the path variables (curvature and distance along path) |
@5:37 | ------> Clone the Template project to create a new one |
@6:21 | ------> Add/change the ground to the cloned project |
@7:25 | ------> Set initial path/vehicle positions |
@8:00 | ------> Set Path parameters |
---------> for radius and distance along path | |
---------> Run a 0 sec simulation and look at path and edit the path | |
@10:00 | ------> Set variables to follow the path |
-----------> on 405 (probe length, PGain and Qgain variables for steer responses) | |
@12:07 | ------> Check the steer, acceleration etc for the vehicle from chart icon/link |
@12:25 | ------> Changing the vehicle speed to 25 mph |
@13:29 | ------> Setting option to use 3 points on probe/wagon tongue (at 75%,100%, 125%) |
@14:06 | ------> Direct comparison of 3Pt v 1 Pt wagon tongue steer |
@14:24 | ------> Collision Interaction OFF Option |
-----------> benefits to set up impact and then turning the collision interaction back on | |
@15:32 | ------> Use of steer table type 2 to insures path follower ends at collision detection |
@16:38 | ------> Determining the time of impact from output files |
@17:04 | ------> Using Tracking View for pan/zoom on the crash sequence |
@17:29 | Recap of steps for Path Follower |
@17:29 | ------> Change the vehicle model/graphics specifications |
------------> (just click on the vehicle and menus to right!) | |
@18:44 | ------> Change the vehicle color |
@20:27 | ------> View the output files of VehicleSteer01.txt and/or VehicleSteer02.txt |
-----------> automatically created when path follower used | |
----------->so you also can insert directly as inputs and delete the path following inputs |
- Fast easy way to get a vehicle to follow a roadway, make a corner, make a lane change
- We recommend using path follower/driver model to determine steer required and then manually input the steer
- We now automatically create the inputs so you can remove the driver model path follower and simply have steer you can then adjust
