According to one example, a working machine includes a projection arrangement to generate a hologram, wherein the hologram presents a virtual operating element or a virtual display and a movement/position detection arrangement to detect a movement or a position of an operator. The working machine of the example also includes a control unit to control the operation of the working machine based on the detected movement or position of an operator and based on the basis of the hologram generated by the projection arrangement, wherein the projection arrangement is to generate the hologram at different positions or with different content in association with different operating positions to be assumed by an operator on an operator platform or the movement/position detection arrangement is designed to detect the movement or the position of an operator in different operating positions on the operator platform.

In the disclosed solution, a boom assembly (14) of a work machine (1) is controlled by tip control. In tip control, a control command is given to a tip of a boom assembly (14), converted into control commands for individual actuators of the boom assembly (14). In the disclosed solution, a variable related to a load and its position at the tip of the boom assembly (14) is defined, and the variable in question related to the load and its position at the tip of the boom assembly (14) is taken into account in the control command for the actuator.

A construction machine traveling control system is provided. The construction machine traveling control system includes first and second electric traveling pedals for outputting manipulation values including electric signals in response to the driver's manipulation and thereby operating first and second traveling motors connected thereto, respectively; a traveling pattern input means installed in the driving room so as to enable the driver to input a construction machine traveling pattern; a controller electrically connected to the first and second electric traveling pedals and to the traveling pattern input means; and a hydraulic circuit electrically connected to the controller so as to control the flow rate of operation oil supplied to the first and second traveling motors, as well as the flow of the operation oil, according to the command values delivered from the controller.

An embodiment of the present invention relates to an apparatus for controlling quick clamping of construction machine which comprises a clamp for mounting an attachment, the apparatus including: a selection input unit for generating a selection signal during an on operation by an operator; an operation input unit for generating an operation signal during an operation by the operator; a clamp driving unit for releasing and fastening the clamp; and a controller for controlling the clamp driving unit to release the clamp while the operation signal is input after the selection signal is input.

A work vehicle, including: a plurality of control valves configured to selectively convey hydraulic fluid to a hydraulic machine, a plurality of controllers connected to said control valves, a terminal including a display screen displaying graphics associated with said valves, a setting button configured to selectively modify a connection between the control valves and the controllers, and modify graphics based on changes of the connection.

A power machine can include operator input devices and a control system configured to command movement of actuators based on operator inputs received from the operator input devices. Movement of one or more of the actuators can be commanded based on input at one or more of the operator input devices and a response curve selected from a plurality of different response curves. Movement of one or more of the actuators can be based on a selected control mode for the power machine that corresponds to a selected control-function mapping of the operator input devices to the one or more actuators. A lift arm can be variously controlled to execute automatic or other operations. An excavator can be operated in a sustained-speed travel mode.

A feedback control device determines a first target angular velocity that is a target angular velocity of an output angular velocity of the target device, using a first transfer function, determines a control input to the target device, based on a difference between the first target angular velocity and the output angular velocity, determines, based on the operation input, a second target angular velocity that is the target angular velocity requested by an operator, determines a degree of comfort of the operator, based on a difference between the output angular velocity and the second target angular velocity, sequentially accumulates the first target angular velocity, the degree of comfort, and a target degree of comfort in a database, and adjusts a first moment of inertia in such a way as to reduce a difference between the target degree of comfort and the degree of comfort, using data accumulated in the database.

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 one-handed joystick for cranes allows an operator to make all necessary motions with a single hand and arm for manipulating various components of a crane. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring, an industrial joystick base, a rocker switch and at least two push button switches. Motions of the rotatable cylinder bar, the rotatable ring, the industrial base and the rocker switch are used to raise and lower the auxiliary hoist; raise and lower the telescopic boom for luffing a hoist; raise and lower the main hoist; slew the boom base in a clockwise or counterclockwise direction; and extend or retract the telescoping boom. The speed of main and auxiliary hosts may be changed with the two push button switches. A Deadman's switch may be installed on a back side of the rotatable cylinder bar.

A one-handed joystick for excavators allows an operator to make all necessary motions with a single hand and arm for manipulating an excavator tool. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring and an industrial joystick base. The rotatable cylinder bar is grasped with a hand. The industrial base is moved front to back, or right to left. The following are preferable hand/arm motions. A downward hand curl is associated with a bucket digging motion; an upward hand curl is associated with a bucket dump; a forearm forward push is associated with a boom/stick extension; a forearm reward pull is associated with a boom/stick retraction; a left-hand movement is associated with swinging the excavator left; a right-hand movement is associated with swinging the excavator right; a clockwise hand twist is associated with a stick/boom extension; and a counter clockwise hand twist is associated with a stick/boom retraction.
