  • Patent number: 10845806
    Abstract: Various technologies described herein pertain to controlling an autonomous vehicle to suppress data corresponding to predefined static objects in a radar output generated by a radar sensor system. A computing system of the autonomous vehicle retrieves prior data for a geographic location from a prior radar space map. The prior radar space map includes prior data for geographic locations in an environment corresponding to whether predefined static objects to be suppressed in radar outputs are located at the geographic locations. The computing system generates a score representative of a likelihood of a tracked object being at the geographic location based on data from the radar output for the geographic location, data from an output of a second sensor system for the geographic location, and the prior data for the geographic location from the prior radar space map. An engine, braking system, and/or steering system are controlled based on the score.

  • Patent number: 10824156
    Abstract: Various technologies described herein pertain to generating an occupancy grid movie for utilization in motion planning for the autonomous vehicle. The occupancy grid movie can be generated for a given time and can include time-stepped occupancy grids for future times that are at predefined time intervals from the given time. The time-stepped occupancy grids include cells corresponding to regions in an environment surrounding the autonomous vehicle. Probabilities can be assigned to the cells specifying likelihoods that the regions corresponding to the cells are occupied at the future times. Moreover, cached query objects that respectively specify indices of cells of a grid occupied by a representation of an autonomous vehicle at corresponding orientations are described herein. An occupancy grid for the environment surrounding the autonomous vehicle can be queried to determine whether cells of the occupancy grid are occupied utilizing a cached query object from the cache query objects.
