Problems solved by technology

Second, due to the lack of longitude and latitude information of new energy vehicles, the dangerous driving behavior detection method based on floating car data is no longer applicable to new energy vehicles, so new methods need to be proposed for dangerous driving detection of new energy vehicles

Embodiment

[0104] In this example, the data is collected from more than a thousand new energy vehicles equipped with collection devices authorized in Shanghai. The data time is one month in a certain year. The data is in days, and the daily data volume is about 300 million pieces. ; The time interval between each piece of data is about 30 seconds, so these data are relatively sparse. Due to the sparsity of data, this embodiment uses mathematical calculations to add complementary data to reduce the sparsity of data as much as possible. Experiments have proved that sparsely selecting data can correctly describe the basic trend of data in most cases. Therefore, the data has the characteristics of large data volume and high data accuracy. At the same time, the data on the number of accidents of these new energy vehicles in the same year is also collected synchronously for subsequent analysis.

[0105] The specific detection method flow is described in detail below. The basic detection metho...

Abstract

The invention discloses a dangerous driving vehicle detection method and device based on new energy vehicle data, and belongs to the field of data mining. According to the dangerous driving vehicle detection method and device based on the new energy vehicle data, the new energy vehicle data serve as the basic, aiming at mass traffic data of a wide range of vehicles, data mining methods such as clustering, fitting and regression are utilized to calculate abnormal accelerated / decelerated behavior characteristic values of the vehicles and abnormal accelerated pedal travel behavior characteristic values, and then total characteristic values responding the vehicle dangerous driving behavior degree of the vehicles are calculated. Through the method, only by inputting operating data of a new energy vehicle in a certain time period, whether the new energy vehicle is a dangerous driving vehicle or not can be judged. Through contrastive analysis of true vehicle traffic accident data, it is known that dangerous driving vehicles can be effectively recognized through the dangerous driving detection method.

Description

technical field [0001] The invention belongs to the field of data mining, and in particular relates to a dangerous driving vehicle detection method and device based on new energy vehicle data. Background technique [0002] Due to the surge in the number of drivers, the driving skills and driving behaviors of drivers are uneven. Some people are not proficient in driving due to their relatively short driving experience, while some people have driving experience for a certain period of time but drive their own way. These are the potential for traffic accidents. factor. Therefore, analyzing the dangerous driving behavior of drivers is of great social significance to road traffic safety. [0003] With the support of new energy vehicle subsidy policies, the further development of new energy vehicles has been vigorously promoted. In recent years, the number of new energy vehicle manufacturers and market ownership has grown by leaps and bounds. The development trend of new energy v...
