Abstract: A method and system for sensing objects disposed about a vehicle includes LIDAR sensors in a LIDAR sensing unit mounted above the vehicle. The system includes outputting a plurality of laser beams from lasers while rotating the LIDAR sensing unit and simultaneously oscillating or changing an axis of rotation for the LIDAR sensing unit.

The oscillating of the LIDAR sensing unit causes the laser beams to change an angle with respect to horizontal during rotation. The change in oscillation or offset angle for an axis of rotation is accounted for by the electronic processor to map the presence of objects. An autonomous vehicle is controlled based on the sensed objects or a warning is provided.
