AI Technical Summary

Problems solved by technology

Generally speaking, the existing research lacks the full use of the current vehicle micro-trajectory data, especially the lane-changing data, which is one of the potential safety hazards. At the same time, the index for identifying abnormal driving behavior is relatively single, and the comprehensive function has not yet been determined.

Embodiment Construction

[0027] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments of the present invention.

[0028] Such as figure 1 As shown, a method for discriminating abnormal driving behavior disclosed in the embodiment of the present invention mainly includes the following steps:

[0029] (1) Obtaining real-time trajectory data of the vehicle, including at least two kinds of data among vehicle speed, acceleration, following distance, vehicle deviation distance and lane change times. The data obtained in this embodiment include: the current vehicle speed v(t), the current vehicle acceleration a(t), the following distance d(t), the distance Δx(t) from the current vehicle’s lane centerline, and the lane change times f LC . Save the real-time trajectory data acquired at the current moment as the historical data for judging abnormal driving behavio...

Abstract

The invention discloses a method and a device for distinguishing abnormal driving behaviors. The method comprises the following steps: acquiring and storing real-time track data of a vehicle, whereinthe track data includes at least two of vehicle speed, acceleration, vehicle spacing, vehicle deviation distance and lane change frequency; reading historical track data of the vehicle, and performingcalculation to obtain a historical average value of the related track data; calculating a composite function value for distinguishing abnormal driving, and determining the danger level of a driving behavior according to the composite function value; and giving an abnormal driving behavior prompting alarm when the danger level of the driving behavior belongs to abnormal driving. The method provided by the invention is convenient in calculation, high in real-time performance and operability, and capable of effectively preventing abnormal driving behaviors such as drunk driving and fatigue driving so as to improve the road traffic safety.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a method and device for judging abnormal driving behavior. Background technique [0002] With the continuous progress of society and rapid economic development, the automobile industry is also advancing by leaps and bounds. According to statistics from the Traffic Management Bureau of the Ministry of Public Security, as of the end of 2016, the number of motor vehicles in the country reached 290 million, including 194 million cars; there were 360 ​​million motor vehicle drivers, including more than 310 million car drivers. Both the number of registrations and the annual increment have reached the highest level in history. With the continuous improvement of people's living standards, the rigid demand for automobiles remains strong, and the number of automobiles maintains a rapid growth trend. In 2016, the number of newly registered automobiles reached 27.52 million, and ...
