AUTONOMOUS WORK VEHICLE OBSTACLE DETECTION SYSTEM
First Claim
1. A work vehicle, comprising:
- at least one sensor configured to detect at least one property of a work area; and
a controller comprising a processor operatively coupled to a memory, wherein the controller is configured to receive a first signal from at least one sensor indicative of the at least one property of the work area, to determine whether an obstacle occupies one or more locations on a two dimensional (2D) surface of the work area by creating or updating a map having a plurality of cells that cover the 2D surface of the work area, one or more cells of the plurality of cells correspond to the locations on the 2D surface of the work area, wherein each cell of the plurality of cells indicates whether the obstacle occupies the cell based on the at least one property, and to output a second signal based on the map.

Abstract
A work vehicle includes at least one sensor configured to detect at least one property of a work area. The work vehicle includes a controller comprising a processor operatively coupled to a memory, wherein the controller is configured to receive a first signal from an at least one sensor indicative of the at least one property of the work area, to determine whether an obstacle occupies one or more locations of the work area by creating or updating a map having one or more cells that correspond to the one or more locations of the work area, wherein each of the one or more cells indicate whether the obstacle occupies the respective locations of the work area based on the at least one property, and to send a second signal based on the map.

8. A work vehicle, comprising:
-
a lidar sensor; and a controller comprising a processor and a memory, wherein the controller is configured to receive a first signal from the lidar sensor indicating distances and directions to an obstacle in a work area, to create or update a point cloud having a set of points based on the distance and directions, to create or update a map of a plurality of cells that cover a two dimensional (2D) surface of the work area, one or more cells of the plurality of cells correspond to one or more locations on the 2D surface of the work area, wherein each cell of the plurality of cells indicate whether the obstacle occupies the cell based on the points of the point cloud, to output a second signal indicative of the map to a control system of the vehicle. - View Dependent Claims (9, 10, 11, 12, 13)

14. A control system for a work vehicle, comprising:
a controller comprising a processor and a memory, wherein the memory is operatively coupled to the processor, wherein the processor is configured to receive a first signal from a first sensor indicating distances and directions to an obstacle in an agricultural field, to create or update a map of a plurality of cells that cover a two dimensional (2D) surface of the agricultural field, each cell of the plurality of cells corresponding to one or more locations on the 2D surface of the agricultural field, wherein each cell of the plurality of cells indicate whether the obstacle occupies the respective locations of the agricultural field, and to output a second signal indicative of instructions to control the vehicle based on the map. - View Dependent Claims (15, 16, 17, 18, 19, 20)
