Method and system for improved vehicle navigation
First Claim
1. A method of revising data in a vehicular navigating system configured to navigate a vehicle to a target point of interest, comprising:
- providing a geographical information database storing location information for a plurality of points of interest and a plurality of roadways;
detecting a charging status of the vehicle;
when the charging status of the vehicle indicates that the vehicle is connected to and charging at a charging station, recording a location of the vehicle;
identifying at least one point of interest in the geographical information database proximate the vehicle using the location of the vehicle;
analyzing the at least one point of interest to determine whether the charging station is publicly accessible; and
only when the charging station is publicly accessible;
using the location of the vehicle when the charging status of the vehicle indicates that the vehicle is charging to update the location information of the charging station within the geographical information database, andusing historical probe data of the vehicle and the location of the vehicle to update the location information of one of the plurality of roadways within the geographical information database, the one of the plurality of roadways providing a route to the charging station.

Abstract
A system and method of revising data in a vehicular navigating system configured to navigate a vehicle to a target point of interest is presented. A geographical information database storing location information for a plurality of points of interest and a plurality of roadways is provided and a charging status of a vehicle is detected. When the charging status of the vehicle indicates that the vehicle is charging, a location of the vehicle is recorded. The location of the vehicle when the charging status of the vehicle indicates that the vehicle is charging is used to update a location of a charging station within the geographical information database.
