Abstract: A method of an interactive server system for providing location information to an in-vehicle terminal includes receiving the location information and indication information from an interactive client, the indication information indicating address information of the in-vehicle terminal, obtaining the address information of the in-vehicle terminal based on the received indication information, sending the location information to the in-vehicle terminal according to the address information of the in-vehicle terminal, and instructing the in-vehicle terminal to generate a navigation path according to the location information.

Abstract: A route-deviation recognition method is provided. The method includes obtaining a current positioned-location; and determining a candidate region covering the positioned-location. Road network data corresponding to the candidate region is obtained to generate a plurality of road-segment tree structures according to the obtained road network data. The method also includes obtaining a matching weight between the positioned-location and each road-segment branch in each of the road-segment tree structures. Further, according to the matching weight, a road-segment branch matching the positioned-location is determined as a matched road-segment branch. The method further includes, when the matched road-segment branch does not belong to a planned navigation route, determining that route-deviation occurs.
