Abstract
A method for estimating the position of a telematics-equipped vehicle during navigation includes: receiving a partial map corresponding to a route; receiving Global Positioning System (GPS) data corresponding to a current position of the vehicle; performing a closest street (CS) mapping based on the GPS data and the partial map so as to provide an estimation for a vehicle position on a street of the partial map; performing speed sum (SS) mapping based on the estimated vehicle position and speed readings corresponding to vehicle speed so as to provide an estimation of distance traveled with reference to a previous vehicle position; and presenting a map matched vehicle position to a user based on the CS mapping and the SS mapping.
