Embodiment Construction

[0074] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0075] refer to figure 1 Shown is a flow chart of an embodiment of the driving behavior analysis method based on vehicle data provided by the present invention. The driving behavior analysis method based on vehicle data includes:

[0076] Step 101, collect the driving data of the vehicle in real time, and at the same time, the OBD box in the vehicle will generate a bit mask for the working status of each driving data collection.

[0077] Wherein, the driving data is obtained by collecting driving-related data in the vehicle, such as GPS data, engine-related data, and G-sensor data on the vehicle. The driving data includes various data involved in the driving process, such as: distance of each trip, driving speed, accele...

Abstract

The invention discloses a driving behavior analyzing method based on vehicle-mounted data. The driving behavior analyzing method comprises the following steps of collecting driving data of automobiles in a real time manner; deleting invalid driving data according to bit mask; performing deletion or modification on exceptional data; performing descriptive statistic on the driving data so as to obtain statistic driving data; through an analytic hierarchy process of group decision, obtaining the weight distribution of evaluating indicators; through a method for scoring by an expert, obtaining scores during a stroke period; through a conformability principle, obtaining the duration of the stroke, the average velocity of the stroke, and the ride comfort scores of the stroke; and according to the weight distribution of the evaluating indicators and the score, obtaining a scoring matrix of the driving data. The invention further discloses a driving behavior evaluation system based on the vehicle-mounted data. According to the driving behavior analyzing method and evaluation system based on the vehicle-mounted data, through the level analysis method of the group decision, the weight of the driving data is obtained, and through the conformability principle, the score of the driving data is obtained, so that the driving behavior of a user can be accurately analyzed and evaluated.

Description

technical field [0001] The invention relates to the technical field of vehicle driving analysis and evaluation, in particular to a driving behavior analysis method and evaluation system based on vehicle data. Background technique [0002] With the continuous development of mobile Internet and Internet of Things technology, more and more vehicles have joined the camp of the Internet of Vehicles through pre-installation or rear-installation, and a large amount of relevant data based on vehicle location, performance and other information has been generated. Through By observing and analyzing these data, we can make a specific evaluation of the user's driving behavior. In this way, we can not only provide reasonable standards or suggestions for vehicle use and user driving, but also facilitate the differentiated management of related industries. For example: in the auto insurance industry, the relevant data of these vehicles has brought new opportunities to the continuous reform...
