Problems solved by technology

If you want to know the air condition of the road section or the place where you go in advance, you need a mobile terminal such as 3G function to inquire about the road section you will pass through or the air condition of the place you will arrive at any time. Use various mobile terminals to inquire about the road section you will pass or the air condition of the place you will arrive at, but it will inevitably affect the fun of travel and even affect driving safety.

Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0049] Considering the impact of air pollution on travel, the navigation method provided by the embodiment of the present invention combines the air pollution index of each area on the basis of the existing navigation method, and performs a new calculation to finally obtain the maximum air pollution degree. Lightweight vehicle navigation routes, and then realize people's healthy travel. Such as figure 1 As shown, the method of the embodiment of the present invention includes:

[0050]Step 1. Collect and record the air pollution index of each area;

[0051] Step 2. According to the air pollution index, determine the vehicle navigation route with the least air pollution.

[0052] The method of the present invention will be described in detail below...

Abstract

The invention discloses a navigation method and system. The navigation method comprises the steps: acquiring and recording an air pollution index of each region; and according to the air pollution index, determining a vehicle navigation route with lowest air pollution degree. According to the navigation method and system disclosed by the invention, the vehicle navigation route with lowest air pollution degree can be screened from a plurality of navigation routes, thus the influence of pollution borne by people in a driving travel, and the healthy travel is realized.

Description

technical field [0001] The invention relates to navigation technology, in particular to a vehicle navigation method and a navigation system. Background technique [0002] PM2.5, also known as fine particulate matter, fine particles or fine particles, refers to particulate matter in the ambient air with an aerodynamic equivalent diameter of less than or equal to 2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, large area, strong activity, and is easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact on human health and...
