Yes, Hybrid A* path planner can consider vehicle dimensions while planning the path.
For that, a new validator class should be written by inheriting any of these two classes: validatorOccupancyMap or validatorVehicleCostmap (These two classes are getting shipped with Navigation Toolbox).
Then in the new validator class, the two collision checking methods: isStateValid() and isMotionValid(), should be defined again which will consider the vehicle dimensions while doing collision checking.
Then this new validator object should be used to create plannerHybridAStar object.
The rest of the steps remains the same. By this, Hybrid A* planner will consider vehicle dimensions while planning the path.
Another simpler solution is to inflate the map with vehicle dimensions.
