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.

1. A vehicle occupant information controller comprising: a fuel volume determining section that determines a remaining fuel volume;a fuel economy determining section that determines a fuel consumption rate;a first distance determining section that determines a first obtainable travel distance based on the remaining fuel volume and the fuel consumption rate;a traveled distance determining section that determines a vehicle traveled distance from a first location to a second subsequent location; anda second distance determining section that determines a second obtainable travel distance based on a difference between a previous obtainable travel distance value corresponding to the first location 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. 2. The vehicle occupant information controller according to claim 1, further comprising a selection section that receives both the first obtainable travel distance and the second obtainable travel distance and that selectively outputs one of the first obtainable travel distance and the second obtainable travel distance based on an operating mode of the vehicle occupant information controller. 3. The vehicle occupant information controller according to claim 1, wherein the second distance determining section decreases the adjusted vehicle traveled distance value when the ratio of the second obtainable travel distance to the first obtainable travel distance is less than a predetermined value. 4. The vehicle occupant information controller according to claim 1, wherein the second distance determining section increases the adjusted vehicle traveled distance value when the ratio of the second obtainable travel distance to the first obtainable travel distance exceeds a predetermined value. 5. The vehicle occupant information controller according to claim 2, wherein the operating mode of the vehicle occupant information controller is based on a geographical location of the vehicle. 6. The vehicle occupant information controller according to claim 2, further comprising a user interface including an operating mode selection feature to manually select the operating mode of the occupant information controller. 7. The vehicle occupant information controller according to claim 1, wherein the traveled distance determining section determines the vehicle traveled distance value based on a change in the remaining fuel volume and the fuel consumption rate. 8. A vehicle occupant information system comprising: a fuel sensor that detects a remaining fuel volume and generates a remaining fuel volume signal indicative of the remaining fuel volume;a speed sensor that detects a vehicle speed and generates a vehicle speed signal indicative of the vehicle speed;an information controller that receives the remaining fuel volume signal and the speed signal, the information controller determines a fuel consumption rate based on values of the remaining fuel volume signal and the vehicle speed signal,a first obtainable travel distance based on the value of the remaining fuel volume signal and a value of the fuel consumption rate,a vehicle traveled distance from a first location to a second subsequent location, anda second obtainable travel distance based on a difference between a previous obtainable travel distance value corresponding to the first location 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. 9. The vehicle occupant information system according to claim 8, further comprising a vehicle ignition operatively connected to the information controller, with the vehicle ignition enabling operation of the information controller. 10. The vehicle occupant information system according to claim 8, further comprising a user display operatively connected to the information controller, with the information controller selectively outputting one of the first obtainable travel distance and the second obtainable travel distance based on an operating mode of the information controller. 11. The vehicle occupant information system according to claim 10, further comprising a user interface operatively connected to the information controller, with the user interface including an operating mode selection feature to manually select the operating mode of the information controller. 12. The vehicle occupant information system according to claim 8, further comprising a fuel consumption sensor that detects a consumed fuel volume and generates a fuel consumption signal indicative of the consumed fuel volume. 13. The vehicle occupant information system according to claim 12, wherein the information controller determines a secondary remaining fuel volume based on a value of the fuel consumption signal, after initial detection of the remaining fuel volume by the fuel sensor. 14. The vehicle occupant information system according to claim 8, wherein the information controller decreases the traveled distance when the ratio of the second obtainable travel distance to the first obtainable travel distance is less than a predetermined value. 15. The vehicle occupant information system according to claim 8, wherein the information controller increases the traveled distance when the ratio of the second obtainable travel distance to the first obtainable travel distance exceeds a predetermined value. 16. The vehicle occupant information system according to claim 10, wherein the operating mode of the occupant information system is based on a geographical location of the vehicle. 17. The vehicle occupant information system according to claim 8, wherein the vehicle traveled distance is determined based on a change in the remaining fuel volume and the fuel consumption rate. 18. A method for operating a vehicle information system comprising: operating a controller to determine a fuel consumption rate based on a remaining fuel volume and a rate of travel;operating the controller to determine a first obtainable travel distance based on the remaining fuel volume and the fuel consumption rate;operating the controller to determine vehicle traveled distance from a first location to a second subsequent location; andoperating the controller to determine a second obtainable travel distance based on a difference between a previous obtainable travel distance value corresponding to the first location 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. 19. The method according to claim 18, wherein the vehicle traveled distance is determined based on a change in the remaining fuel volume and the fuel consumption rate.
