PURPOSE:To allow the parallel displacement to a target position by correcting a drive signal outputted from a control unit to a front wheel steering driving device and a rear wheel steering driving device on the basis of the detection result from an inclination sensor. CONSTITUTION:A drive signal is outputted from a control unit 17 to a front wheel steering driving device 11 and a rear wheel steering driving device 14 on the basis of the steering operation signal from a remote controlled setter 19, and a moving working vehicle is steered. At the time of running operation by the same phase mode, the drive signal is corrected on the basis of the detection result from an inclination sensor 18 so that the steering angles of a valley side front wheel 1 (2) and a valley side rear wheel 3 (4) are conformed to each other. Thus, the front wheels 1, 2 and the rear wheels 3, 4 can be steered so as to conform the steering angles of the valley side front wheel 1 (2) and the valley side rear wheel 3 (4) to each other. In the case of displacing the moving working vehicle in parallel obliquely on an inclined ground, it can be precisely moved to a target position. |
