In-vehicle equipment, vehicle, and method

A vehicle travel route control system controls a plurality of vehicles having an autonomous driving function or a driving assist function, wherein a vehicle dispatch information data server creates a travel route map, in which driving mode switching position at which vehicles have switched over during travel to the manual driving mode from the autonomous driving mode, have been added to a road map. Based on the travel route map, a travel route that avoids the driving mode switching position is calculated from among a plurality of routes on which a dispatch vehicle candidate travels to a destination via user position. When a travel route that avoids the driving mode switching position is calculated, a dispatch vehicle candidate is set as a dispatch vehicle, and the calculated travel route information is transmitted to an on-board unit mounted in the dispatch vehicle.
