| With the growth of the national economy,the number of vehicles in our country is also growing rapidly,with more vehicles on the road,traffic accidents are more frequent.One of the main causes of traffic accidents is the dangerous driving behavior of drivers,such as speeding,sharp turns,tired driving,etc.If the dangerous driving behavior is detected and warned in time,traffic accidents can be reduced.Therefore,this paper carries out the research on driving behavior evaluation system based on the Internet of vehicles,including vehicle data collection,wireless data transmission,cloud server data processing,driving behavior evaluation and mobile application data display.The system evaluates driving behavior according to the evaluation rules,which can help drivers correct dangerous driving behavior and avoid traffic accidents.The research work of this paper is as follows:(1)The demand analysis is carried out,and the driving behavior evaluation system based on the Internet of vehicles is designed.The system consists of vehicle terminal,cloud server and mobile application.The vehicle terminal collects and uploads the required vehicle data;The cloud server receives the data by the vehicle terminal,evaluates the driving behavior according to the established evaluation rules,and designs a database for storing relevant data;The mobile application displays the vehicle driving data,driving behavior data,driving behavior evaluation results and other data.(2)Based on the collected vehicle data,the driving behavior evaluation rules are researched and designed.Make judgment rules for dangerous driving behavior,judge dangerous driving behavior according to vehicle data;The characteristic parameters related to driving behavior are selected,and the characteristic parameters of driving behavior are calculated according to the number of dangerous driving behaviors and driving data;Evaluation indexes are determined according to dangerous driving behavior and driving data,and different scoring weights are assigned to different indexes.Scoring rules of evaluation indexes are designed,and driving behavior evaluation is conducted based on this,so as to ensure driving safety.(3)System test and analysis.An experimental platform was built to test the system’s data collection,data upload,driving behavior evaluation results display and other functions.The test results show that the vehicle terminal can collect the vehicle data and upload the data to the cloud server;The cloud server can receive,process and store data;The mobile application can display driving data and driving behavior evaluation results,indicating the feasibility of the system.To sum up,the system completes the collection of vehicle data,evaluates the driving behavior according to the rules formulated by the collected data,and feedbacks the evaluation results to the driver through the mobile application,which helps the driver timely understand and correct the dangerous driving behavior and reduce the traffic accidents caused by the dangerous driving behavior. |
