  • Publication number: 20210002860
    Abstract: A remote operation system for a working machine includes a control device enabling an operator wearing a wearable display to grasp the surrounding situation of himself/herself. The control device includes an operation intention judgment section judging the presence/absence of an operator's operation intention to a remote operation lever based on the contents of acquired judgment information, and a display image switching section. With judgment of presence of the operation intention, the display image switching section makes a working area image taken by a working area image taking camera be displayed in a particular display area of the wearable display. With judgment of absence of the operation intention, the display image switching section stops the display of the working area image in the at least a part of the particular display area and switches it to a surrounding visual-recognition allowing area allowing the operator to visually recognize the surroundings.

  • Publication number: 20200399861
    Abstract: A construction machine capable of suppressing deterioration in work efficiency includes an angle detecting device that detects a relative angle between a lower travelling body and an upper slewing body, a travel lever that can be manipulated to make the lower travelling body travel, a display, a directional information generating unit that generates information related to a travelling direction of the lower travelling body based on a detected result of the angle detecting device, and a display controller. The display controller causes the display to display an arrow image indicating the travelling direction of the lower travelling body generated by the directional information generating unit when the travel lever is manipulated and does not permit the display to display the arrow image when the travel lever is not manipulated.

  • Patent number: 10583824
    Abstract: A vehicle includes a left clutch provided on a path for transmitting driving torque to a left rear wheel and a right clutch provided on a path for transmitting driving torque to a right rear wheel torque. If a command value of the driving torque distributed to the left rear wheel using the left clutch and a command value of the driving torque distributed to the left rear wheel using the right clutch fall respectively below predetermined lower limit values, a control device controls the command values of the driving torque to be predetermined lower limit values. While realizing an optimal torque distribution control, accuracy of the driving torque distributed to the left and right rear wheels (auxiliary drive wheels) can be improved by preventing the command values (command torque) distributed to the left and right rear wheels from becoming small below the limit.
