Embodiment Construction

[0060] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] Such as figure 1 as shown, figure 1 It is a flow chart of the first embodiment of the individual driving behavior feature recognition method of the present invention. The individual driving behavior feature recognition method mentioned in this embodiment comprises steps:

[0062] Step S10, receiving the vehicle positioning data of the current driver detected by the terminal;

[0063] In this embodiment, modeling and recognition are performed on the driving habits of the same driver. When the current driver is driving the vehicle, the vehicle's driving route and vehicle positioning data are obtained through the positioning system on the terminal. The terminal can include a GPS recorder installed on the vehicle, a mobile phone and a PAD with GPS function, or a terminal installed on a Positioning application s...

Abstract

The invention discloses an individual driving behavior characteristic recognition method. Vehicle positioning data of a current driver detected by a terminal is received; multiple conventional driving characteristic indexes are extracted from the vehicle positioning data; multiple mel frequency cepstrum coefficient MFCC characteristic indexes are extracted from the vehicle positioning data; and the conventional driving characteristic indexes and the MFCC characteristic indexes act as training samples, and modeling is performed by using a random forest classification method so that the driving behavior characteristic recognition model of the current driver is acquired. The invention also discloses an individual driving behavior characteristic recognition device. Modeling is performed by aiming at the vehicle positioning data of the current driver acquired by the terminal positioning function so that the data acquisition mode and acquisition equipment are simple and cost can be saved; besides, the driving behavior characteristic recognition model acquired through modeling can further reflect the individual driving behavior characteristics of the current driver so that the more accurate recognition effect can be acquired in the subsequent individual driving behavior recognition.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for identifying individual driving behavior characteristics. Background technique [0002] With the continuous development of the automobile industry, more and more users own vehicles, traffic congestion is becoming more and more serious, and the risk of traffic accidents is also increasing. In order to alleviate traffic pressure and reduce the probability of traffic accidents, formulating specific driving behavior guidance items for different car owners' driving habits has become the main development trend of the auto service industry. At present, most of the feature analysis based on vehicle driving behavior is to embed sensor equipment in the vehicle body, and collect data such as the physical state of the motor vehicle movement, the driver's physical state, and the environment outside the vehicle through the sensor, and then perform data processing and a...
