OCCUPANT-DEPENDENT SETTING SYSTEM FOR VEHICLE, AND VEHICLE

An occupant-dependent setting system for a vehicle includes a setting processor, a server apparatus including a server memory, and first and second authentication processors. On the condition that the occupant is authenticated by the first authentication processor, the second authentication processor acquires, from the vehicle, data regarding the occupant and data regarding the vehicle, and authenticates a combination of the occupant and the vehicle. On the condition that the combination of the occupant and the vehicle is unauthenticatable by the data regarding the occupant and the data regarding the vehicle, the second authentication processor authenticates the combination of the occupant and the vehicle, by a combination of account data regarding the occupant and the vehicle. The account data is held by an occupant terminal of the occupant on board the vehicle to make access to the server apparatus.
