Abstract
A position measurement portion manages a measurement target area by dividing the area into a plurality of section areas, and also manages, or keeps track of, an intra-area interfering object number which is the number of interfering objects in a given section area, independently for each of the plurality of the section areas. The travel controller determines, independently for each of the plurality of section areas, if the section area is in a congested state in which the intra-area interfering object number is greater than a set upper limit number, and selects a congested area travel mode as the travel mode when the travel controller is about to cause the vehicle to travel in a section area that is determined to be in the congested state.
