Vehicle control system and vehicle control method

摘要

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.

1. A vehicle control system comprising:
a vehicle capable of traveling in a measurement target area; a travel controller which controls travel of the vehicle; a position measurement portion which measures a position of the vehicle within the measurement target area and positions of a plurality of interfering objects within the measurement target area; wherein the travel controller is configured to control travel of the vehicle based on position information of the vehicle in the measurement target area and position information of the plurality of the interfering objects, measured by the position measurement portion, wherein the position measurement portion is configured to manage the measurement target area by dividing the measurement target area into a plurality of section areas, and is configured to manage an intra-area interfering object number, which is the number of interfering objects in a section area, independently for each of the plurality of the section areas, and wherein the travel controller is configured: to control travel of the vehicle in any one of a plurality of travel modes; to determine, 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, based on the measurement information from the position measurement portion; wherein the travel controller is configured to select a normal travel mode as the travel mode when the travel controller is about to cause the vehicle to travel in the section area that is determined to be not in the congested state, and to select a congested area travel mode as the travel mode when the travel controller is about to cause the vehicle to travel in the section area that is determined to be in the congested state, and wherein in the congested area travel mode, the travel controller is configured to set an upper limit travel speed for the vehicle to a congestion upper limit travel speed which is less than an upper limit travel speed in the normal travel mode.
