Abstract: An information distribution center includes a controller that searches for a route from a departure place to a destination place as a search route and searches for access points on the search route. The controller selects, based on distribution information, a first access point that can communicate with a mobile terminal apparatus when a vehicle is turned on and that corresponds to a first portion of the distribution information and selects, based on distribution information, a second access point along the search route that corresponds to a second portion of distribution information. The controller then transmits the first portion of the distribution information to the first access point and transmits the second portion of the distribution information to the second access point.

Abstract: A vehicle navigation apparatus is capable of detecting a current vehicle position with improved accuracy. The reliability factor of a distance coefficient is reduced when a vehicle runs in an area having a large altitude gradient or when a position detection error is detected between a current vehicle position calculated using the distance coefficient and a current vehicle position calculated based on GPS position data. When the vehicle runs at a high speed, the distance coefficient is modified depending on the running speed. After the distance coefficient is determined via learning, if a position detection error is detected for a road which the vehicle has previously traveled, a position detection cost is assigned to the road. Factors that can cause a position detection error are minimized, thereby making it possible to detect a current vehicle position with high accuracy.
