A work vehicle includes an automatic running control unit 51 that executes automatic running based on an own vehicle position and a target running path; a manual running control unit 52 that executes manual running based on an operation signal from a manual running operation unit 9 that is manually operated; a first control unit 61 that executes a change from manual running to automatic running, a manual stoppage of the vehicle being a condition for the change; a second control unit 62 that executes a forced stoppage of the vehicle when changing from automatic running to manual running; and a third control unit 63 that executes a forced stoppage of the vehicle by temporarily suspending automatic running in response to a suspend instruction from the manual running operation unit 9, and resumes automatic running in response to a resume instruction from the manual running operation unit 9.

A work vehicle includes a hydraulic actuator, a hydraulic pump, an operation member, a control valve, an angular velocity corresponding value sensing unit, a notification component, and a controller. The actuator changes a steering angle based on a supplied fluid. The pump supplies fluid to the actuator. The operation member is operated by an operator when the steering angle is changed. The valve controls flow of fluid supplied from the pump to the actuator based on an amount the operation member is operated. The sensing unit senses a corresponding value corresponding to a steering angular velocity changed based on the flow of fluid. The notification component notifies that the corresponding value has reached a threshold value preset based on an upper limit of the steering angular velocity. The controller causes the notification component to perform a notification when it is detected that the corresponding value has reached the threshold value.

A steering device for operating a work vehicle includes a support part, a base member rotatably supported by the support part, a lever rotatably supported by the support part or the base member, a biasing member and a transmission mechanism connecting part. The biasing member is interposed between the lever and the base member to bias the lever to a predetermined position with respect to the base member. The transmission mechanism connecting part configured to be connected to a transmission mechanism configured to transmit rotation based on a rotation angle of a steering shaft of the work vehicle to the base member. A restriction part may restrict rotation of the lever when an angle of the lever with respect to the base member reaches a predetermined angle.

A work machine including a vehicle body, a traveling wheel, first and second steering members, an actuator, first and second operation sensors that output operation signals indicative of operation of the first and second steering members, and a controller. The controller acquires the first and second operation signals. The controller determines whether or not the first steering member is being operated, and whether the first steering member was operated last. The controller performs an automatic control of the actuator to set the steering angle to a target angle upon determining that the first steering member is not being operated and the first steering member was operated last. The controller does not perform the automatic control upon determining that the second steering member was operated last even if the first steering member is not being operated.

A controller disables the motion of a steering cylinder brought about by a steering lever when an enabled state is selected via a lever switch and an instruction to start an engine is issued via a main switch.

There is a need for a work vehicle that allows accurate traveling time management in a work site traveling. A work vehicle includes a vehicle body mounting a traveling mechanism, an implement mounted on the vehicle body and configured to effect a ground work on a work site, a satellite positioning module 80 for outputting positioning data, a traveling distance calculation section 51 for calculating a traveling distance of the vehicle body based on the positioning data, a traveling time calculation section 52 for calculating an actual distance traveling time from a time required for traveling of traveling distance calculated by the traveling distance calculation section 51 and a work management section 50 for managing the ground work based on the actual distance traveling time.

A utility vehicle comprises a plurality of ground engaging members and a frame supported by the plurality of ground engaging members. The frame includes a front frame portion, a mid-frame portion, and a rear frame portion. The utility vehicle further comprises an attachment supported at the front frame portion. Additionally, the utility vehicle includes an operator area supported by the frame and including an operator seat and an adjacent passenger seat spaced apart from the operator seat. The operator seat and the passenger seat are in a side-by-side arrangement. The utility vehicle also comprises an auxiliary power assembly having an attachment shaft configured to be operably coupled to the attachment. The attachment shaft extends in a generally longitudinal direction of the utility vehicle and projects outwardly from the front frame portion.

A method for automatically guiding a motor grader includes receiving a desired final grade for a worksite and generating a steering path for steering the motor grader across the worksite and moldboard control instructions for actuating a moldboard of the motor grader as the motor grader moves across the worksite based at least in part on the desired final grade, at least one steering performance metric of a steering system of the motor grader, and at least one moldboard performance metric of a moldboard system of the motor grader. Moreover, the method includes receiving an input indicative of a ground speed of the motor grader. Additionally, the method includes controlling the steering system according to the steering path and the moldboard system according to the moldboard control instructions when the ground speed is within a threshold speed range.

A system may comprise a plurality of sensors configured to transmit sensor information regarding a speed of a machine, a position of an implement of the machine, a payload of the machine, a grade of a surface on which the machine is traveling. The system may further comprise an electronic control module configured to receive steering command information regarding a steering command of the machine; determine, based on the steering command information, one or more articulation parameters associated with the steering command, determine the speed, the position of the implement, the payload, and the grade based on the sensor information. The electronic control module may be configured to determine one or more articulation parameters thresholds based on the speed, the position of the implement, and the payload of the machine; and modify the steering command when the one or more articulation parameters exceeds the one or more articulation parameters thresholds.

A control system is disclosed. The control system may include a first input component to control a lean angle of at least one set of wheels of a machine and to provide a visual and/or tactile indication of the lean angle. The control system may include a second input component to control an articulation angle of an articulated joint of the machine and to provide a visual and/or tactile indication of the articulation angle. The control system may include a third input component to control a rotation angle of an implement of the machine and to provide a visual and/or tactile indication of the rotation angle.
