Method for calculating optimum driving path

The invention discloses a method for calculating an optimum driving path. The method comprises the following steps: firstly collecting stroke data of current entry of each vehicle-mounted intelligent terminal by virtue of an information centre; inputting a starting point, a finishing point and a scheduled arrival time on the intelligent terminal by a user before driving; searching from an internal database of the intelligent terminal or transferring the database of the information center and transferring the driving path data meeting the requirement; automatically adapting the driving path; screening factors with the absolute values which are minimal and are closest to a target driving time in a driving time range required by that day by the intelligent terminal by virtue of internal calculation as the final target data; and arranging in a descending manner according to the driving time and displaying the preferable path on the vehicle-mounted intelligent terminal according to rankings and finally screening by the user. According to the method, the intelligent terminal has the characteristics of self-record and self-calculation. Based on self resources assisted by Internet data, real-time networking is not required, and the problems of removing signal interference and network flow are solved.
