Abstract: Process for clearing an autonomous machine including first evaluating operation at a high curvature offline location. Following acceptable operation, the machine is placed into service and evaluated at a worksite. Following acceptable worksite operation, online operating speed of the machine is increased incrementally, and performance reevaluated. Following acceptable performance characteristics, online operating speed of the machine continues to be increased and revaluated until the machine reaches maximum designated operating speed, or is evaluated as unacceptable, in which case the machine continues to operate at the last acceptable online operating speed and identifies the unacceptable performance characteristic for further evaluation.

Abstract: A tracking problem detection system for a machine may include tracking diagnostic circuitry including one or more tracking diagnostic processors configured to receive a location signal indicative of a location of a machine and a path signal indicative of a path location associated with at least a portion of a path for the machine to follow while maneuvering. The tracking diagnostic processors may also be configured to determine a tracking difference between the path location and the location of the machine, and determine a frequency of a signal associated with the tracking difference and/or a frequency of a signal associated with a yaw rate associated with the maneuvering. The tracking diagnostic processors may also be configured to detect, based at least in part on the frequencies of the signals associated with the tracking difference and/or the yaw rate, a tracking problem associated with maneuvering the machine.

Abstract: A speed planning device is disclosed. The speed planning device may perform a method including obtaining elevation information associated with a route for a vehicle; identifying a section of the route based on the elevation information, wherein the section is associated with a change in elevation; determining subsections of the section; determining respective slopes of the subsections and respective lengths of the subsections; obtaining information identifying a mass associated with the vehicle; generating a speed plan for the vehicle to traverse the section, wherein the speed plan indicates one or more speeds at which the vehicle is to correspondingly traverse the subsections based on the respective slopes of the subsections, the respective lengths of the subsections, and the mass associated with the vehicle; and providing the speed plan to permit the vehicle to be controlled to traverse the section according to the one or more speeds of the speed plan.
