A straight traveling apparatus for a construction machine and a control method thereof are provided which can allow a curved travel when the working device is operated during the curved travel.

A system for determining an optimized cut location for a work implement includes a position sensor and a controller. The controller is configured to determine the position of a work surface and perform a coarse analysis along a path based upon the position of the work surface and a coarse analysis parameter threshold to select a selected coarse analysis increment. The controller is further configured to perform a fine analysis along the selected coarse analysis increment based upon the position of the work surface and a fine analysis parameter threshold to select the optimized cut location.

The disclosed technology relates to an intelligent motion control system that utilizes onboard sensors and processing to guide a surface manipulation machine along a path of travel on a surface, confirm a position of the machine with respect to the surface, and actuate a surface manipulation tool to achieve a desired surface profile or locate a point of interest. The system may include a first and second surface profiler that is configured to scan a surface on which the system travels and a positional sensor configured to generate positional data representing a position of the machine. The processor is configured to generate topography data based on output received from the first surface profiler, generate intermediate data based on output received from the second profiler, compare the intermediate data with the topography data to calculate an offset; and control motion of the system based on the offset.

A first process acquires movement data including a position of a lead machine. A second process controls one or more work machines so that the one or more work machines follows the lead machine based on the movement data.

The invention relates to a method for controlling an autonomous vehicle in a worksite. The method comprises the steps of: receiving a predetermined trajectory of a work sequence of the autonomous vehicle, the predetermined trajectory including at least a set path and a set speed; adding a pre-defined variation to the predetermined trajectory to form a test trajectory, the variation including at least a variation in set path or set speed; comparing the energy usage over the test trajectory and the predetermined trajectory; determining whether or not the compared energy usage achieves a pre-set criteria; and setting the test trajectory as a new set trajectory of the autonomous vehicle in response to determining that the compared energy usage achieves the pre-set criteria.

A vehicle (2) comprising at least one working unit (4) and a vehicle control system (6) comprising control units for controlling the vehicle to work in accordance with one or many working procedures. The vehicle is provided with a plurality of sensor units (12) configured to generate a sensor signal (14). Each control unit (8) is configured to determine control signals (18) to control its working unit (4), and the control unit designated to the vehicle is configured to determine control signals to control the vehicle, and also to determine control signals (18) for controlling at least one of the other working units (4) or the vehicle, and specifically to determine control signals (18) capable of controlling steps of a working procedure. At each point in time one of the control units is a master control unit being the control unit that is responsible for controlling its own working unit (4) and also at least one other working unit (4), and that at least two control units (8) are configured to be a master control unit. A determination procedure is provided to continuously determine if handover to another control unit, then being the new master control unit, should be made, and enabling the new master control unit to take control in accordance with the current working procedure if handover has been determined.

Embodiments of the present disclosure relate generally to generating and utilizing three-dimensional terrain maps for vehicular control. Other embodiments may be described and/or claimed.

A mining machine is disclosed. The mining machine may include a mobile ranging device, a movement sensor device, and a control unit. The mobile ranging device may be configured to communicate with a location sensor device and cause the location sensor device to transmit location data relating to a location of the mining machine. The movement sensor device may be configured to transmit movement data relating to a movement of the mining machine. The control unit may be configured to receive coordinate data relating to a plurality of zones and a plurality of drawpoints of a tunnel, the location data, and the movement data. The control unit may identify an active zone, determine a machine heading, determine a machine articulation, identify an active drawpoint based on the active zone, the machine heading, or the machine articulation, and cause an action to be performed in connection with the active drawpoint.

Disclosed embodiments include power machines or loaders, and systems used on loaders, configured to augment the control of the loader to accomplish repetitive tasks. Also disclosed are methods of learning a task for augmented control of a loader, and methods of controlling a loader to perform a learned task to provide augmented control of the loader.

A system may determine that an upcoming pass is a final pass associated with loading a machine. The system may compute, based on determining that the upcoming pass is the final pass, a trigger time associated with causing a trigger signal to be transmitted. The trigger time may be computed based on a final pass completion time that identifies a time at which the final pass is expected to be completed. The trigger time may be prior to the final pass completion time. The system may cause the trigger signal to be transmitted at the trigger time. The system may cause, based on a receipt of the trigger signal, a transition of the machine from an idle state to a ready state to be initiated. The transition from the idle state to the ready state may be caused to be initiated prior to a time at which the final pass, associated with loading the machine, is completed.
