摘要： In an electrically driven construction machine, decrease in the remaining electric power storage amount of an electric power storage device is reduced when a transition to auto idle control takes place in case where the remaining electric power storage amount is small, and the duration over which the remaining electric power storage amount of the electric power storage device lasts is lengthened. Accordingly, a controller 31 controls the rotation speed of an electric motor 1 such that the rotation speed of the electric motor 1 is lowered from a predetermined rotation speed to an idle rotation speed Ni when none of a plurality of operation devices 20, 21, 22, 23a, 23b, and 24 is manipulated and a predetermined time duration TD has elapsed. In addition, when the remaining electric power storage amount of an electric power storage device 33 is equal to or smaller than a first threshold Ea, the controller 31 sets the predetermined time duration TD shorter than when the remaining electric power storage amount is greater than the first threshold Ea.

摘要： A control method of a work machine in which a rotation number of a fan that takes outside air into an engine room accommodating an engine varies with a rotation number of the engine, includes: executing first control of regenerating a collecting filter unit that collects particulates contained in exhaust gas of the engine by a temperature rise of the exhaust gas; when the work machine is changed from a steady state to a specific state, executing second control of decreasing an amount of working oil discharged from a hydraulic pump by driving of the engine; and, when the first control and the second control are concurrently executed, executing third control of increasing the rotation number of the engine.

摘要： Described herein is a visual indication system implemented on a mobile machine. The visual indication system at least partially surrounds the mobile machine and includes a plurality of displayable regions. Objects surrounding the mobile machine are detected using an object detection sensor. A direction with respect to the mobile machine is detected for each of the objects. A current state of the mobile machine is determined. An object-directed indicator for each of the objects is generated based on the current state of the mobile machine. The object-directed indicator for each of the objects is displayed on the visual indication system at a particular displayable region based on the direction of the particular object.

摘要： An earth moving vehicle (EMV) autonomously performs an earth moving operation within a dig site. If the EMV determines that a state of the EMV or the dig site triggers a triggering condition associated with a pause in the autonomous behavior of the EMV, the EMV determines a risk associated with the state or triggering condition. If the risk is greater than a first threshold, the EMV continues the autonomous performance and notifies a remote operator that the triggering condition was triggered. If the risk is greater than the first threshold risk but less than a second threshold risk, the EMV is configured to operate in a default state before continuing and notifying the remote operator. If the risk is greater than the second threshold risk, the EMV notifies the remote operator of the state pauses the performance until feedback is received from the remote operator.

摘要： Systems and methods are disclosed for managing task assignments for a plurality of work machines at a site. An assignment engine may: receive first state data for a work machine including historical data, operating condition, and location data, and second state data for the site including characteristic data for materials and a plurality of available tasks; predict performance data and energy consumption data of the work machine for a task; select a task for the work machine by inputting first state data and second state data into a trained reinforcement-learning model, wherein: the model has been trained to learn an assignment policy that optimizes a reward function such that the learned policy selects a task for at least one work machine from the plurality of tasks available at the site; and cause the at least one work machine to be operated according to the at least one task assignment.

摘要： Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle θ of a brake pedal 43 increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer 33 is equal to or less than the predetermined pedal angle θth, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.

摘要： A work machine includes a vehicle body, a work implement movably connected to the vehicle body, a plurality of actuators that are connected to the work implement and change an orientation of the work implement with respect to the vehicle body, an operating device that is operable to change the orientation of the work implement, a sensor that detects the orientation of the work implement, and a controller. The controller acquires a current orientation of the work implement, determines a target orientation of the work implement corresponding to an operation of the operating device, determines respective target stroke lengths of the plurality of actuators so that the work implement assumes the target orientation from the current orientation with a combination of stroke motions of the plurality of actuators, and controls the plurality of actuators based on the target stroke lengths.

摘要： A work machine includes an undercarriage, a swing body swingably supported by the undercarriage, and work equipment operably supported by the swing body. A control system controls the work machine. The control system includes a processor. The processor generates a design plane that is defined by a plane on a vehicle body coordinate system of which origin is a representative point of a swing body. The processor rotationally converts the design plane around the origin of the vehicle body coordinate system in association with a swing of the swing body. The processor specifies a position of the work equipment in the vehicle body coordinate system. The processor controls the work equipment based on the specified position of the work equipment and the design plane.

摘要： A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve f(x)=4.641e0.34x. The value “x” represents a horizontal direction and the function f(x) represents a vertical direction.
