Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] During the implementation of the present invention, the travel data collection software is developed based on the Android platform, and is suitable for standard Android system smart phones on the market. The software supports the system version 4.0 at most, and is backward compatible to version 2.2. software interface such as figure 2 As shown, the part shown in (1) is the data display part. When the smart phone system obtains the corresponding position information, speed information and acceleration information, it will be displayed in real time on the display part; the part shown in (2) is the control button part , used to control the recording operation of the database; (3) The part shown is the menu part, which includes the function of uploading data and the option of exiting.

[0028] During the recording process, the software uses 1Hz as the sampling fre...

Abstract

The invention discloses vehicle green travel navigation system design based on a smart phone, and particularly relates to a green navigation system and method with which in any time and space range, travel pollutant emission evaluation and prediction of a vehicle can be achieved. The system comprises a travel data collection part and a green travel navigation part. Through popularity and portability of the smart phone, in cooperation with a VSP pollutant emission model of the vehicle, travel information of a large number of users is obtained conveniently with low expense so as to construct a historical database, and the information is converted into visual and visible pollutant emission data through the green travel navigation part. Because the influence on the city pollutant emission level caused by the travel of the owner of the vehicle is visually known, the purpose that the traffic travel behaviors are improved, and the total pollutant emission amount of the motor vehicles is reduced can be achieved.

Description

technical field [0001] The invention belongs to the field of intelligent transportation systems, and in particular relates to the design of a smart phone-based vehicle green travel navigation system, a vehicle green travel navigation system and method for estimating and predicting vehicle pollutant emissions within any time and space. Background technique [0002] With the rapid construction of cities, people are becoming more and more accustomed to using route query websites to query travel routes. Currently, the most used route query websites are mainly Google Maps and Baidu Maps. This type of route query website can provide the user with multiple routes and related information in various ways according to the information input by the user. The travel methods included mainly include self-driving, bus travel and walking. The relevant information includes not only the road information of the resulting route, but also the time-consuming and actual distance information of the...
