Abstract: A work machine includes a vehicle body, a work implement, an attitude sensor, an object sensor, and a controller. The work implement is movably attached to the vehicle body. The attitude sensor detects the attitude of the work implement. The object sensor is attached to the work implement. The object sensor detects an object in a periphery of the work machine, and outputs a signal indicating a presence of the object. The controller sets a detection determination range of the object sensor. The controller determine the presence of the object in the detection determination range based on the signal from the object sensor. The controller calculates sensor attitude data including at least one of a position and an orientation of the object sensor, based on the attitude of the work implement. The controller modifies the detection determination range in accordance with the sensor attitude data.

Abstract: A work machine includes a vehicle body, a traveling wheel, a steering actuator, an articulation actuator, an articulation angle sensor, and a controller. The vehicle body includes a rear frame and a front frame. The front frame is connected so as to be able to articulate left and right with respect to the rear frame. The traveling wheel is supported by the vehicle body. The steering actuator steers the traveling wheel to the left or right. The articulation actuator changes an articulation angle between the rear frame and the front frame. The articulation angle sensor detects the articulation angle. The controller performs an automatic steering control that automatically steers the traveling wheel by controlling the steering actuator. The controller acquires the articulation angle. The controller limits travel of the vehicle body or limits the automatic steering control according to the articulation angle.

Abstract: A work vehicle capable of notifying surroundings about information of the work vehicle at appropriate timing is provided. The work vehicle includes a blade, a shutter, a notification unit, and a controller. The blade includes a lower end. The shutter is attached to the blade. The shutter can be alternatively disposed at a first position at which the shutter protrudes forward from the lower end of the blade or at a second position at which the shutter is farther away from the lower end than at the first position. The notification unit is configured to notify surroundings of the work vehicle about information of the work vehicle. The controller is configured to change information notified by the notification unit in accordance with an arrangement of the shutter at one of the first position and the second position.

Abstract: A work machine includes a vehicle body, a traveling wheel, a steering actuator, a leaning actuator, a leaning angle sensor, and a controller. The traveling wheel is supported by the vehicle body. The steering actuator changes a steering angle of the traveling wheel. The leaning actuator changes a leaning angle of the traveling wheel. The leaning angle sensor detects the leaning angle. The controller performs an automatic steering control that automatically steers the traveling wheel by controlling the steering actuator. The controller acquires the leaning angle. The controller limits travel of the vehicle body or limits the automatic steering control according to the leaning angle.

CPC classification number: E02F9/2083 , E02F3/841
Abstract: A work machine is provided that can achieve an automatic brake retention function without hindering work. The work machine includes a vehicular body that travels, a work implement supported on the vehicular body, an accelerator operation device operated to increase a traveling speed of the vehicular body, a brake operation device operated to decrease the traveling speed of the vehicular body, and a controller. The controller performs automatic brake retention control to retain a braking force to maintain a travel-stopped state of the vehicular body when the traveling speed of the vehicular body becomes less than or equal to a threshold by operation of the brake operation device, and release the retention of the braking force by operation of the accelerator operation device. The controller determines whether work is being performed by the work implement, and when work is being performed, disables the automatic brake retention control.

Abstract: A work vehicle that includes a steering mechanism and a controller that controls the steering mechanism is disclosed. The controller includes a vehicle data input that receives data on a position and/or an azimuth of the work vehicle, and a steering controller that specifies deviation of the work vehicle from a prescribed travel path by comparing the prescribed travel path with the data and controls the steering mechanism of the work vehicle such that the work vehicle returns to the prescribed travel path based on an amount of the deviation.
