摘要： PROBLEM TO BE SOLVED: To obtain a traveling control method allowing a traveling object to satisfactorily travel along lines such as weld lines traveling to a prescribed direction on a three-dimensional traveling face. SOLUTION: In this method for controlling the traveling of a traveling body, detection information with weld lines 3 existing on a traveling face as a reference line is detected, and the traveling of a traveling body which is steered while adhered to the traveling face is controlled based on a traveling control command generated by a traveling control command generating means 7 based on the detected detection information. In this case, the deviation in a position of the traveling body reference position in a reference line crossing direction with respect to the reference line is detected, and the inclination of the traveling body reference axis to the reference line is detected, and a first traveling control command to reduce the deviation in a position is generated based on the detected deviation in a position, and a second traveling control command to reduce the inclination of the traveling body reference axis is generated based on the detected inclination of the traveling body reference axis. Thus, the traveling of the traveling body can be controlled.
