PROBLEM TO BE SOLVED: To provide a work vehicle simplifying steering control even in a work vehicle in which a center of a work width and a vehicle body reference point are deviated in a vehicle body transverse direction.SOLUTION: The work vehicle comprises: a steerable travel unit； a work unit； a first travel route generation section that generates a first travel route after which a work width center as a center of the work width of the work unit follows； a second travel route generation section that generates a second travel route after which a vehicle body reference point as a reference point of automatic steering control in the vehicle body follows, on the basis of the first travel route and a displacement value between the work width center and the vehicle reference point； a vehicle body reference point calculation section for calculating a location of the vehicle body reference point on the basis of positioning data； and a steering amount calculation section for calculating a steering amount in the automatic travel on the basis of deviation between the second travel route and the location of the vehicle body reference point.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2019,JPO&INPIT【課題】作業幅の中心と車体基準点とが車体横断方向でずれている作業車においても、操舵制御が簡単となる作業車を提供する。【解決手段】作業車は、操舵可能な走行装置と、作業装置と、作業装置の作業幅の中心である作業幅中心が追従する第１走行経路を生成する第１走行経路生成部と、車体における自動操舵制御の基準点となる車体基準点が追従する第２走行経路を、第１走行経路と、作業幅中心と車体基準点との位置ずれ値とに基づいて生成する第２走行経路生成部と、測位データに基づいて車体基準点の位置を算出する車体基準点位置算出部と、自動走行時に第２走行経路と車体基準点の位置との偏差に基づいて操舵量を算出する操舵量算出部とを備える。【選択図】図７
