Embodiment Construction

[0019] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] figure 1 It is a flowchart of an embodiment of the navigation path selection method of the present invention, such as figure 1 As shown, the navigation path selection method includes:

[0021] Step 101. Obtain fuel consumption coefficients corresponding to various fuel consumption factors of each route between the departure point and the destination.

[0022] Wherein, during the running process of the user's vehicle, there are many factors that may cause an increase in fuel consumption. In the embodiment of the present invention, these factors that increase fuel consumption are referred to as fuel consumption factors. The fuel consumption factor may include: at least one of curvature, slope, road conditions, traffic congestion, etc., and the corresponding fuel consumption coefficient may be obtained according ...

Abstract

The embodiment of the invention relates to a navigation path selecting method and a device. The navigation path selecting method comprises: obtaining an oil consumption coefficient corresponding to various oil consumption factors of each path between a staring position and a destination; according to the length of each path and the oil consumption coefficient, obtaining the oil consumption degreeof each path; according to the oil consumption degree of each path, selecting the path with lowest oil consumption. The embodiment of the invention can obtain the oil consumption degree of each path according to the oil consumption coefficient, the path length and the like of each path between the staring position and a destination and select a path which saves maximal oil for users, which not only saves fuel oil consumption of vehicle of the user and lowers energy consumption, but also reduces environment pollution and protects the environment.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a navigation route selection method and device. Background technique [0002] The global positioning system (Global Position System; GPS for short) navigation function has been more and more accepted by people. Generally, GPS navigation can plan multiple routes between the starting point and the destination. When users use the GPS navigation function, they often have certain requirements for the route given by the system. For example, some users require the shortest distance, some users require expressway priority, and some users request not to take high speed, etc. Most of the existing GPS navigation functions use the method of shortest distance priority and expressway priority for path planning. [0003] In the process of realizing the present invention, the inventor at least finds that the prior art has at least the following problems: ...
