Planning, Mapping, and Control

Path planning, costmaps, geographic map display, vehicle controllers

Automated Driving Toolbox™ provides several features that support path planning, mapping, and vehicle control.

  • For planning driving paths, you can use a vehicle costmap and the optimal rapidly exploring random tree (RRT*) motion-planning algorithm. You can also check the validity of the path and smooth the path.

  • For mapping, you can access and visualize high-definition map data from the HERE HD Live Map (HERE HDLM) web service. You can then use this data to develop driving algorithms. You can also stream geographic coordinates on various maps by using the geoplayer function.

  • For vehicle control, you can use lateral and longitudinal controllers that enable autonomous vehicles to follow a planned trajectory.
