Abstract

The invention discloses a driving behavior evaluation method based on FCM clustering and a BP neural network, belonging to the technical field of the Internet of vehicles. The method comprises the following steps: querying a driving satellite positioning signal set of a sample vehicle from an Internet-of-vehicles database as a sample data set; extracting the driving behavior characteristic parameters of the sample vehicle from the sample data set; building a cluster platform based on Spark of Hadoop to run an FCM clustering algorithm, and getting a clustering result of the driving behavior characteristic parameters according to the preset number of clusters; creating a BP neural network, normalizing the clustering result of the driving behavior characteristic parameters, and taking the normalized clustering result as a training sample to train the created BP neural network; and using the trained BP neural network to evaluate a normalized driving behavior to be evaluated. By mining and analyzing Internet-of-vehicles data, driving behavior evaluation is more accurate and scientific.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a posture behavior evaluation method based on FCM clustering and BP neural network. Background technique [0002] In recent years, with the rapid development of Internet of Things technology and the continuous popularization of Internet of Vehicles technology, Internet of Vehicles mobile devices such as vehicle terminals generate a large amount of Internet of Vehicles data all the time, and it is very convenient to use these devices to realize the monitoring, dispatching and monitoring of large-scale vehicles. Remote management, so as to improve the efficiency of vehicle use, and facilitate the management of government and enterprise vehicles. [0003] At present, the evaluation of driving speed behavior is generally through a series of driving behavior deduction units: rapid acceleration deduction unit, rapid deceleration deduction unit, sharp turn deduction uni...
