Abstract: A collision detection system including a proximity sensor, positioning sensor, and controller. The controller includes a memory storing instructions, and a model of the machine that includes dimension information of the machine, location information of the proximity sensor, and pose information of movable portions of the machine. A processor is connected to the proximity sensor, positioning sensor, and memory, and is configured to update pose information of the model based on the pose of the movable portions determined using the positioning sensor. The processor may receive a detection of the object from the proximity sensor. The processor may determine an expected detection result of the proximity sensor using the model, and based on the location information of the proximity sensor and the updated pose information. The processor may compare the detection with the expected detection result to determine whether the detection results from the movable portion or a foreign object.

Abstract: A collision avoidance system and method for a mobile machine includes determining a boundary zone and providing a notification and/or control command to prevent a collision with another object. A first safety zone associated with a first and second portion of the mobile machine is determined. A second safety zone associated with the second portion of the mobile machine is determined. A boundary zone is determined as a function of a combination of the first and second safety zone. A notification and/or a control command is provided based on a relationship of an object to the boundary zone.
