ABSTRACT:
A location detecting apparatus comprising a road map memory having road map data stored therein, a heading sensor for sensing a heading of a vehicle, a velocity sensor for sensing a velocity of the vehicle to obtain distances traveled by the vehicle, a location detecting unit for calculating an estimated location of the vehicle on the basis of the integrated distances and heading and for detecting a current location of the vehicle on a road on the basis of a degree of similarity between the estimated location and the road map data, a road searching unit for searching a road that is ahead of the current location detected by the location detecting unit, a predicting unit for calculating a predicted transverse acceleration to which the vehicle is exposed, on the basis of a radius of curvature of the searched road and the velocity sensed by the velocity sensor, and a warning unit for comparing the transverse acceleration with a predetermined threshold value and for giving warning to a vehicle operator if the transverse acceleration is greater than the predetermined threshold value.
