Embodiment Construction

[0040] The present invention will be further described below in conjunction with accompanying drawing.

[0041] An environment-friendly vehicle navigation path construction method based on real-time road condition information, comprising the following steps:

[0042] Step 1: Fusion of key information on vehicle energy consumption. Energy consumption during vehicle driving is related to many factors, such as the power of the engine in different driving states, the speed and time of vehicle driving, the geographical conditions of the driving road, and the physical state of other machines. In the present invention, through a large number of experimental analysis, select road basic information (road number, road length, road slope coefficient), the quantity, quality, driving speed and driving power of the current vehicle on the road are used as building energy consumption / exhaust gas emission model and path Selected criteria.

[0043] In the first step above, the energy consumpt...

Abstract

The invention discloses an environment-friendly vehicle navigation path construction method based on real-time traffic status information. The method comprises the steps that real-time traffic road and vehicle information is integrated, a travelling path with the minimum vehicle energy consumption is calculated and obtained, and the path obtained through calculation in the vehicle travelling process is updated in real time, so that energy consumption and tail gas emission are lowered, and the probability of traffic jams is decreased. According to the method, a road gradient coefficient and vehicle real-time travelling speed are selected as basic information for performing modeling on a road traffic net, an energy consumption model and a tail gas emission model are obtained respectively, the vehicle navigation path with the minimum energy consumption is obtained based on the models and a Dijkatra algorithm, vehicle energy consumption and carbon dioxide emission are lowered, and green travelling of urban vehicles is convenient.

Description

technical field [0001] The invention relates to an environment-friendly vehicle navigation path construction method based on real-time road condition information, and belongs to the technical field of intelligent vehicle traffic network path navigation. Background technique [0002] In the urban road traffic system, it is required to provide real-time driving route navigation services for vehicles based on real-time road condition information, which can not only provide reasonable driving routes for travelers, avoid traffic congestion, but also reduce vehicle energy consumption and carbon dioxide and other exhaust gases. emissions, so as to build an ecologically harmonious green transportation system. Therefore, research on the design of vehicle navigation algorithms based on environment-friendly has attracted people's attention. In recent years, a variety of classification studies and comparisons of route navigation based on different road information have been proposed. H...
