    Abstract: The invention relates to a self-propelled construction machine and to a method for controlling a self-propelled construction machine. The construction machine according to the invention has a position-determining device 13 for determining the position of a reference point R on the construction machine in a coordinate system (X, Y, Z) independent of the construction machine. The position-determining device has a navigation satellite system receiver 14 for receiving satellite signals from a global navigation satellite system 15 (GNSS) and a computing unit 16 which is configured so that the position of a reference point (R) on the construction machine and the orientation (ψ) of the construction machine can be determined based on the satellite signals in a coordinate system (X, Y, Z) that is independent of the construction machine. Moreover, the construction machine has a controller 18 which cooperates with the position-determining device 13 configured to adjust the steering angles of the steerable running gears 3, 4, 6 so that the reference point R of the construction machine moves along a set trajectory T. The computing unit 16 of the position-determining device 13 is configured so that, in a control mode in which the control of the construction machine is not based on the satellite signals of the global navigation satellite system 15, the position (xn, yn, zn) of the reference point (R) relating to the construction machine and the orientation (ψ) of the construction machine are determined in the coordinate system (X, Y, Z) that is independent of the construction machine while the construction machine is moving on the basis of a kinematic model 16A implemented in the computing unit 16 of the position-determining device 13 which describes the position (P) of the reference point (R) and the orientation (ψ) in the coordinate system (X, Y, Z) that is independent of the construction machine depending on the steering angles and the speeds of the running gears 3, 4, 6.

    Abstract: A remote control station includes an operator interface for remotely controlling at least one work operation. The operator interface includes at least one control device and an indication system having a first symbol associated with a plurality of control patterns of the at least one control device. The operator interface further includes a display device configured to display a plurality of control patterns thereon. Each of the plurality of control patterns includes a second symbol substantially similar to the first symbol. The remote control station also includes a controller configured to store the plurality of control patterns associated with the at least one control device. The controller is configured to receive an input signal from the operator interface for activation of one of the plurality of control patterns and transmit an output signal for performing the at least one work operation.

    Abstract: The present disclosure relates techniques for autonomously controlling heavy equipment and vehicles using task hierarchies. Particularly, aspects of the present disclosure are directed to obtaining a task to be performed by an autonomous vehicle, determining subtasks to be performed to perform the task, obtaining sensor data providing a representation of operation of the autonomous vehicle in a worksite environment and situational context of the worksite environment, determining a task context for a subtask based on the sensor data, identifying a predictive model from a library of predictive models based on the task context, estimating, by the predictive model, a set of output data based on sensor data, and controlling operations of the autonomous vehicle in the worksite environment to perform the subtask using a set of input data derived from the sensor data and the set of output data.

    Abstract: An unmanned vehicle control method for setting a permitted area where traveling is permitted for each unmanned vehicle, the unmanned vehicle control method includes: acquiring unmanned vehicle data including position data of the unmanned vehicle; acquiring road surface condition data of a travel path on which the unmanned vehicle travels; and generating data including a permitted area in the travel path of the unmanned vehicle, a stop point in the permitted area, and a target traveling speed for the unmanned vehicle to stop at the stop point on a basis of the unmanned vehicle data that has been acquired, wherein the permitted area is set on a basis of the road surface condition data of a predetermined area including the stop point.
