Problems solved by technology

[0005] There are many detection contents, including drunk driving, speeding driving, fatigue driving, etc., which require more detection equipment and increase the cost; the utilization of on-board equipment resources is ignored, resulting in low utilization of on-board equipment, such as on-board radar sensors , driving recorder, etc.

Abstract

The invention relates to a recognition device and method for the radical driving state of a driver. The recognition device comprises a data collecting unit, a processing unit and a voice prompt unit. The data collecting unit collects the image of a lane where a target car runs, the speed and the distances between the target car and front and back cars, transmits the collected target car information to the processing unit and obtains the lane deviation amount and speed of the target car, and the speeds of the front and back cars. In addition, the processing unit works out the radical driving degrees of the driver in the transverse and longitudinal directions through the processed information. When the radical driving degrees in the transverse and longitudinal directions are larger than a threshold value, the target car is in a radical driving state, and the driver is provided with early warning information through the voice prompt unit.

Description

technical field [0001] The invention relates to the technical field of driving behavior recognition, in particular to a device and method for recognizing a driver's aggressive driving state. Background technique [0002] With the rapid increase in the number of cars and the rapid development of roads, our country is facing very serious traffic safety problems, among which the proportion of accidents caused by aggressive driving by drivers is increasing, especially those caused by aggressive driving on expressways. The series of traffic accidents caused heavy casualties and property losses. The detection of the driver's aggressive driving state mainly focuses on the detection of the driver's physical characteristics, such as pulse rate, heart rate, eye blinking, etc. [0003] The Chinese patent application 200610012623.6 whose publication number is CN1830389 discloses a "fatigue driving state monitoring device and method" (inventors: He Guohong, Li Xiaoming, Li Airong, Liang...
