A display device for a shovel that includes an attachment including a boom, an arm, and an end attachment includes an operation analysis start input part and an operation analysis check input part. The operation analysis start input part is configured to be operated to start an operation analysis of the shovel and store the history of the operation analysis. The operation analysis check input part is configured to be operated to display the result of the operation analysis.

The wheel loader (10) includes a vehicle main body (1), a rear detection section (71), a vehicle main body angle sensor (72), and a controller (26). The rear detection section (71) detects an obstacle (5) in the rear of the vehicle main body (1). The vehicle main body angle sensor (72) detects the inclination state of the vehicle main body (1). The controller (26) determines the control corresponding to the detection by the rear detection section (71), based on the inclination state of the vehicle main body (1) detected by the vehicle body angle sensor (72).

A load in a bucket is weighed accurately in a short time period. A work machine includes a bucket and a controller. The controller determines a period in which a parameter related to a load weight in the bucket fluctuates with respect to time. The controller averages load weights at a plurality of time points within the period to calculate an average load weight.

A work machine control system includes: a pump; a cylinder operating a working equipment element in a movable range based on hydraulic oil supplied from the pump; a first path connected to the pump; a second path branching from the first path; a control valve adjusting the flow rate of the oil supplied to the cylinder via the first path; a bleed valve adjusting the flow rate of the oil discharged to a tank via the second path; a sensor detecting a posture of the element in the range; and a control device outputting a first command for adjusting the flow rate of the oil supplied to the cylinder and a second command for adjusting the flow rate of the oil discharged to the tank when element is determined to be present in an end section of the range based on detection data of the sensor.

A machine may include an implement; one or more sensor devices; and a controller. The controller may be configured to receive, from the one or more sensor devices, data regarding a ground surface on which the machine is to perform a digging operation; transmit the data to one or more remote computing devices to cause the one or more remote computing devices to generate digging information based on the data; and receive the digging information from the one or more remote computing devices. The digging information may include information identifying a sequence of digging locations in an area of the ground surface and information identifying corresponding dumping locations. Based on the digging information, the controller may be configured to cause the machine to navigate to a digging location of the digging locations, and cause the implement to initiate the digging operation at the digging location.

A control system for a work vehicle includes a controller. The controller acquires actual topography data indicating an actual topography to be worked. The controller determines a target design topography indicating a target trajectory of a work implement of the work vehicle based on the actual topography. The controller acquires an uneven surface parameter indicating the degree of surface unevenness of the actual topography. The controller changes the target design topography according to the uneven surface parameter.

A system for controlling an engagement operation between first and second movable machines includes a separation sensor, a relative speed sensor and a controller. The separation sensor determines a separation distance between the first and second machines. The relative speed sensor determines a relative difference in speed between the first and second machines. The controller determines the separation distance between the first and second machines, decelerates the first movable machine when the separation distance is within a deceleration zone, determines a relative difference in speed between the first and second machines, and generates an engagement speed command to operate the first movable machine at a first ground speed equal to a second ground speed of the second movable machine plus a relative engagement speed when the separation distance is within a buffer zone.

A control may obtain first data related to a plurality of positions of an implement of a work machine during a first time period and may determine, based on the first data, a first noise value related to at least one velocity of the implement for the first time period. The control device may obtain second data related to a plurality of positions of the implement during a second time period and may determine, based on the second data, a second noise value related to at least one velocity of the implement for the second time period. The control device may determine, based on the first noise value and the second noise value, a start of motion of the implement. The control device may cause, based on determining the start of motion of the implement, the implement to be calibrated.

A system for controlling movement of multiple links of an excavator can move a tool at the end of an excavator arm. The system includes a sensor data interface configured to receive sensor data for determining relative orientations of the multiple links with respect to each other, and a surface setting unit configured to access design data defining a reference surface. The system has a remapping unit configured to remap a user command for moving two links with respect to each other about a corresponding joint to a rotatory tool degree of freedom. The system then coordinates output signals, such that as a function of the remapped user command the tool is rotated within the associated rotatory tool degree of freedom, without the need that an operator coordinates underlying joint movements.

A work vehicle includes a work implement operatively connected to a frame through an actuator having a cylinder and a piston rod. Control circuitry is operatively connected to the actuator and includes a processer and a memory, wherein the memory is configured to store program instructions and the processor is configured to execute the stored program instructions to: identify one of an initial retracted reference position of the piston rod based on an initial minimum retracted distance or an initial extended reference position of the piston rod based on an initial maximum extended distance; identifying an end of stroke position of the piston rod after identifying one of the initial retracted reference position of the piston rod or the initial extended reference position of the piston rod; and moving the work implement with respect to the work vehicle based on a work implement command modified by the identified end of stroke position.
