  • Collision avoidance system with elevation compensation
    Patent number: 11059480
    Abstract: A propulsion and collision avoidance system is associated with a machine operating on the ground, and is configured to determine whether a collision will occur based upon the pose and movement of the machine and the pose of the obstacle. The slope of a straight line between the machine and the obstacle is determined based upon the pose of the machine and the pose of the obstacle, and the slope of the straight line is compared to a slope threshold. A collision alert is generated after determining that a collision will occur and when the slope of the straight line is less than the slope threshold, and continuing propulsion commands are generated to propel the machine along the work surface after determining that a collision will occur and when the slope of the straight line is greater than the slope threshold.
