Embodiment Construction

[0051] The method of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] The realization of urban road network operation status analysis technology includes several parts. The first one is the fuel consumption data collection based on CAN bus. The main content of data collection includes the realization method of data collection, the content of data collection and the transmission of data. The second is driving behavior analysis. The main content of driving behavior analysis includes driving behavior classification (mainly including start-stop analysis, overtaking analysis, idling analysis), and the relationship between different driving behaviors and energy consumption. The third is the analysis of congested road sections, through the analysis of energy consumption data to determine the congested road sections in the road network. The fourth is the analysis of road network operation status. The basis ...

Abstract

The invention relates to a road network running condition analysis system based on fuel consumption acquisition. The road network running condition analysis system comprises a fuel consumption acquisition module arranged on a vehicle, and a driving behavior analysis module, a fuel consumption obtaining module and a congestion state obtaining module which are arranged at a data processing center, wherein the fuel consumption acquisition module is used for acquiring fuel consumption data of the vehicle; the driving behavior analysis module is used for obtaining behavior types of a driver according to the acquired fuel consumption data, and the behavior types of the driver can be classified into vehicle starting and stopping, overtaking and idling; the fuel consumption obtaining module is used for obtaining the total fuel consumption on a section of the road according to an instantaneous fuel consumption value; and the congestion state obtaining module is used for judging whether a road where the vehicle is positioned is in a congestion state according to whether a congestion prejudging state occurs and the times of the congestion prejudging state behavior that occurs in a set time section T, that is, the road is defined to be in a congestion state when the frequency of the congestion prejudging state behavior that occurs is higher than 3 times. The congestion prejudging state is defined to be a state that the starting and stopping state of a vehicle is between twice idling of the vehicle. The system further comprises a congestion grading module.

Description

technical field [0001] The invention relates to the field of urban road network operation state analysis, in particular to a road network operation state analysis system based on fuel consumption collection. Background technique [0002] The current method of analyzing the road network operation status is mainly to judge the congestion situation of the road sections that make up the road network. CAN bus of prior art is a kind of field bus, and it is a kind of serial data communication protocol developed by German Bosch Company to solve the data exchange between numerous control and test instruments in modern automobiles, the communication schematic diagram of CAN bus is as follows attached figure 1 shown. [0003] The basic data used in the existing road network operation state analysis methods are mostly road network traffic flow operation parameters. The three basic parameters of road network traffic flow are speed, density and volume. The existing technology finally ...
