Problems solved by technology

But the most critical problem is that the roads are complex. When you are driving on a road, there must be a lot of road information around. How to match the vehicle to the correct road and send it to the engine industrial control to control the engine speed range It is very important. If the obtained road grade information is wrong or changes repeatedly, it will bring unnecessary adjustment of the engine range, which will not only fail to achieve the purpose of fuel saving, but also affect driving and bring certain dangers.

Embodiment Construction

[0034] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0035] As a specific example, such as figure 1 As shown, a method for accurately classifying vehicle driving roads according to the present invention comprises the following steps:

[0036] Step 1: Obtain the driving data of the vehicle, which is obtained through the vehicle-mounted GPS module. For the specific implementation process of this step, refer to figure 1 In the road topology shown, a vehicle W starts from point s on road a and travels towards road c. Road d is an interfering road that may cause positioning errors. There is a branch exit b at the node of road a and road c, and the vehicle starts. The vehicle starts to drive on the road from point s, and the vehicle's driving data is acquired at an interval of 1S, and the driving data includes current position, speed, and direction information.

[0037] Step 2: According to the road topol...

Abstract

The invention relates to the technical field of vehicle traveling road level division. According to the vehicle traveling road level precise division method disclosed by the invention, a precise vehicle traveling road level method is provided. The vehicle traveling road level precise division method comprises the steps of: obtaining traveling data of a vehicle in real time, calculating matched road information based on the traveling data and navigation map data, calculating most possible traveling road information of the vehicle in a first time section deltaT1 by using a statistical calculation method, and further obtaining a correct traveling road level of the vehicle in complex and interferential roads through a vehicle traveling road level judgment method.

Description

technical field [0001] The invention relates to the technical field of classifying vehicle driving roads, in particular to a method for accurately classifying vehicle driving roads, which can be used to control engine industrial control to perform fuel-saving control according to the road class. Background technique [0002] With the popularization of automobiles and the rapid development of roads between cities, automobiles have become an important tool of life, and automobile manufacturers are also facing a very large market space. Similarly, when cars become an indispensable tool in everyone's life, everyone's driving habits are often different. Today, energy issues and environmental issues are becoming more and more prominent, and how to save fuel has become an important issue. For a car, the engine is the heart, which determines the power of the car. In the case of low gear, if the engine speed is too high, it is easy to cause idling, and the energy is wasted but cannot...
