A management system for a work vehicle configured to carry out a utility work while traveling autonomously includes a work field information acquisition section for acquiring work field information indicative of information relating to a work field where the work is to be carried out, a route information acquisition section for acquiring route information indicative of a traveling route along which the vehicle has traveled, a consumed electric power information acquisition section for acquiring electric power information indicative of consumed electric power, a tilt angle information acquisition section for acquiring tilt angle information indicative of a tilt angle of the work field relative to the horizontal plane, and a calculation section for calculating a cost required for the work, based on the work field information, the route information, the electric power information and the tilt angle information.

Management system and management method

A work vehicle configured to carry out a utility work while traveling autonomously includes an implement unit mounted on a vehicle body for carrying out the work, a work subject information acquisition section for accruing work subject information indicative of information on a work subject, a load calculation section for calculating a load of the work based on the work subject information, a storage section for storing driving conditions of the implement unit in advance, and a driving section configured to retrieve a driving condition stored in the storage section according to the load calculated by the load calculation section and to drive the implement unit based on the retrieved driving condition.

Work vehicle

A work area determination system for an autonomous traveling work machine which is controlled autonomously based on self machine position information indicative of a self machine position, the work area determination system including an operation terminal capable of determining a work area. The operation terminal includes a positioning device for acquiring terminal position information indicative of a position of the operation terminal, a work area determination section that determines the work area based on the terminal position information, and a work area information outputting section for outputting work area information which is information relating to the determined work area.

A vibration-isolating device for a steering wheel of a travelling working vehicle equipped with a wheel steering mechanism includes a first steering shaft () that transmits rotational displacement, the first steering shaft being operatively connected to the steering wheel (); a second steering shaft () that transmits rotational displacement, the second steering shaft being operatively connected to the wheel steering mechanism (P,); and a vibration-isolating connecting mechanism () that operatively connects the first steering shaft () and the second steering shaft () to each other so that rotational displacement can be transmitted. When the angles of rotational displacement of the first steering shaft () and the second steering shaft () are within ranges of rotation angles for linearly driving the vehicle, rotational displacement cannot be transmitted between the first steering shaft () and the second steering shaft ().
