Abstract
An auto traveling work vehicle includes a first control computation section for outputting a first steering value computed for deviation resolution based on a positional deviation between a target traveling path and a self vehicle position, a second control computation section for outputting a second steering value computed for the deviation resolution based on the positional deviation and a directional deviation which is adjusted with using a weight coefficient which provides a progressively decreasing tendency with increase in the positional deviation, a target steering computation section for outputting a target steering value for traveling along the target traveling path based on the first steering value and the second steering value, a steering driving control section configured to input the target steering value and to output a steering driving signal, and a steering driving section for effecting steering of a steerable wheel based on the steering driving signal.
