This display device includes a display unit, a receiving unit, and a control unit. The display unit displays a first screen having a selection item display area. The receiving unit receives a command for selecting a selection item displayed in the selection item display area. The control unit displays, on the basis of alarm information which indicates that an error has occurred, an alarm mark image in the selection item display area. When the alarm mark image is displayed in the selection item display area, the control unit assigns, to the receiving unit, a function of receiving an alarm mark selection command which is the command for selecting the alarm mark image. When the receiving unit receives the alarm mark selection command, the control unit displays, on the display unit, a second screen for indicating the content of the error.

A working machine includes a display unit, a reception unit, and a display processing unit. The display unit displays a first screen that displays a first mark indicating a set function and a second screen for setting the function. The reception unit receives an instruction of setting a function when the display unit displays the second screen. In response to reception of the instruction of setting the function by the reception unit, when the display unit displays the second screen, the display processing unit causes the display unit to display a second mark corresponding to the first mark and superimposes the second mark on the second screen.

A tipping avoidance system configured to modify operation of a collision avoidance system. The tipping avoidance system may include a payload determination system configured to generate a payload signal, and a load position determination system configured to generate a load position signal. The tipping avoidance system may also include a tipping avoidance controller configured to receive the payload signal and the load position signal, and determine, based at least in part on the payload signal and the load position signal, a minimum stopping distance at or above which the machine will not tip due at least in part to deceleration of the machine from a travel speed to a stopped condition. The tipping avoidance controller may be configured to communicate with a braking controller, such that the braking controller adjusts a stop triggering distance based at least in part on the minimum stopping distance.

A controller obtains topographical data indicative of the topography of a work site. The controller obtains material data indicative of the position of a material. The controller computes an evaluation function based on the material data for each of a plurality of candidates of the travel path to be decided from the topographical data. The evaluation function includes a material function pertaining to an amount of the material. The controller decides a candidate having a smallest evaluation function of the plurality of candidates as the travel path.

A vehicle control system for an off-road vehicle including a processing circuit including a processor and memory, the memory having instructions stored thereon that, when executed by the processor, cause the processing circuit to receive a first parameter associated with a characteristic of the off-road vehicle, receive a second parameter associated with a characteristic of an environment of the off-road vehicle, generate, based on the first and second parameters, a perception zone for the off-road vehicle, control the off-road vehicle to avoid an obstacle using the perception zone, receive an indication of a change in at least one of the first parameter or the second parameter, and update the perception zone based on the change in the at least one of the first parameter or the second parameter.

Systems and methods are provided for navigating based on sensed brake light patterns. In one implementation, a navigation system for a host vehicle may include at least one processing device. The at least one processing device may be programmed to receive, from a camera, a plurality of images representative of an environment ahead of the host vehicle; analyze the plurality of images to identify at least one target vehicle in the environment ahead of the host vehicle; identify, based on analysis of the plurality of images, at least one brake light associated with the target vehicle and at least one characteristic associated with changes in an illumination state of the at least one brake light; and cause a navigational change for the host vehicle based on the identified at least one characteristic associated with the changes in the illumination state of the at least one brake light.

A control device of a work vehicle includes a required output torque determination unit that determines a required output torque of the power transmission device based on an operation amount of the operation device and a traveling speed of the work vehicle, a traveling load estimation unit that estimates a traveling load torque related to a traveling load on the work vehicle, a required output torque correction unit that corrects the required output torque such that the required output torque is included in an allowable output torque range including an estimated traveling load torque, and a drive source control unit that outputs a control signal for the drive source based on a corrected required output torque.

Provided is a wheel loader in which the speed position of the transmission can be easily changed with a small number of switches. The wheel loader 1 includes a tilting angle sensor 9 for detecting the tilting angle of the vehicle body. In case that the vehicle body is traveling on an uphill or a downhill with a transmission 33 in a higher speed position than the lowest speed position, and the tilting angle detected by the tilting angle sensor 9 is not smaller than a prescribed threshold value, a transmission control device 45 sends the transmission 33 a command to downshift the transmission 33 one speed position by each operation of a shiftdown switch 62.

A hydraulic energy handling system for a working machine includes a high-pressure side; a low-pressure side; a hydraulic machine for mechanically driving, and being mechanically driven by, a mechanical driveline of the working machine; at least one high-pressure hydraulic energy storage connected to the high-pressure side; a hydraulic motor; a hydraulic pump arranged to supply hydraulic fluid to an inlet side of the hydraulic motor; and a return line for conducting hydraulic fluid to a hydraulic tank. The system further includes a pressure relief valve between the high-pressure side and the return line and arranged to discharge excess hydraulic energy from the high-pressure side to the return line to provide a braking force on the mechanical driveline; and a priority valve arrangement connected to an outlet side of the hydraulic motor to direct a prioritized flow of hydraulic fluid to the low-pressure side.

A method of controlling a mobile machine having a set of ground engaging elements includes receiving an image of terrain proximate the mobile machine, detecting a contour of the terrain, determining a projected path of the set of ground engaging elements based on the detected contour of the terrain, and controlling a display device to display the image with an overlay representing the projected path of the ground engaging elements.
