A method of automatically turning an autonomous mining truck (AMT), including front wheels and rear wheels, around in an operating area, including retrieving boundary data associated with the operating area, determining a first path to follow to execute a turn maneuver within the operating area based at least on the boundary data and dimensions of the AMT, wherein the first path includes a number of legs necessary to follow the first path through the turn maneuver, completing a first leg of the turn maneuver, determining a second path to follow and number of legs necessary to execute the turn maneuver based on an inability to execute the first path, and executing the second path to complete the turn maneuver.

Automatic steering of vehicle

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.

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.

Speed planning device for a vehicle

A control system for a machine traveling on a work surface is provided. The control system includes a perception system generating data indicative of a contour of the work surface. The control system includes a controller communicably coupled to the perception system. The controller receives a signal indicative of a current position of the machine on the work surface as the machine travels along a first direction. The controller initiates a scanning of the work surface by the perception system. The controller receives the signal indicative of the contour of the work surface from the perception system and identifies a raised contour and a contour edge within a target area on the work surface. The controller determines a location of the contour edge within the target area based on the identification and controls a positioning of the machine within the target area and relative to the raised contour.
