Abstract: An anti-lock braking system for an autonomous vehicle includes a memory storing instructions relating to braking control, a detection system for detecting an event necessitating braking of the autonomous vehicle, and a controller. The controller is in communication with the detection system and is configured to execute the instructions to receive detection and identification of the event, determine a vehicle deceleration rate based on the identification of the event, and operate the anti-lock braking system in a selected mode of a plurality of different predetermined operating modes based on the vehicle deceleration rate.

Abstract: 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.

Abstract: A controller may configure the machine to operate in a plurality of modes including a manned control mode, a remote control mode, and an autonomous control mode. The controller may receive a request to cause the machine to perform an action; and determine a requested mode of operation of the machine associated with the request. The requested mode of operation may be one of the plurality of modes. The controller may selectively deny the request or enable the machine to perform the action based on a priority assigned to a current mode of operation of the machine and a priority assigned to the requested mode of operation.

Abstract: A position identification system for use with a mobile machine at a worksite is disclosed. The system may include an integration module configured to integrate information from at least one motion sensor and at least one GPS receiver to generate a location signal indicative of an actual location of the mobile machine. A controller may be provided in communication with the at least one motion sensor, the at least one GPS receiver, and the integration module, the controller being configured to determine the reliability of information received from the at least one motion sensor, the at least one GPS receiver, and the integration module, and following a period of time from when received information is first determined to be unreliable, switching from determining the position of the mobile machine using information determined to be unreliable to determining the position of the mobile machine using dead reckoning from a last known good position of the mobile machine, a determined wheel speed of the mobile machine, and a steering command being provided to the mobile machine.

Abstract: A method for controlling a mining truck travelling on a work site is disclosed. The method includes receiving payload information associated with a payload carried in a bed of the mining truck from sensors associated with the mining truck. The method further includes determining an imbalance of the payload based on the payload information. The method further includes receiving positioning data associated with the work site from a positioning system and determining an approaching terrain of the work site based on the positioning data. The method further includes planning a path for the mining truck based on the imbalance and the approaching terrain and controlling the mining truck based on the path.

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.
