A vehicle occupant information controller includes a fuel volume determining section, a fuel economy determining section, a first distance determining section, a traveled distance determining section and a second distance determining section. The first distance determining section determines a first obtainable travel distance based on a remaining fuel volume from the fuel volume determining section and a fuel consumption rate from the fuel economy determining section. The traveled distance determining section determines a vehicle traveled distance between two locations. The second distance determining section determines a second obtainable travel distance based on a difference between a previous obtainable travel distance value and an adjusted vehicle traveled distance value, with the adjusted vehicle traveled distance value being equal to a product of the vehicle traveled distance and a distance adjustment factor that is selectively adjusted based on a ratio of the second obtainable travel distance to the first obtainable travel distance.
