An abnormal driving behavior recognition method based on vehicle state and driver state

Abstract

The present invention claims to protect a method for identifying abnormal driving behavior based on vehicle status and driver status, comprising the steps of: obtaining current vehicle driving information from a V2X vehicle-mounted terminal OBU, judging the lane where the vehicle is located through the V2X roadside equipment RSU or map information, and obtaining the Lane direction angle, combined with vehicle heading information to determine the vehicle's driving state. Use the on-board camera to obtain the video sequence of the driver's driving state, analyze the driver's driving state through the driver's abnormal state monitoring algorithm, realize real-time monitoring of the driver's state, and use key points to monitor whether non-drivers interfere with driving, Realize monitoring of non-drivers. Finally, the state information obtained above is processed in a unified manner, the current vehicle driving state is judged, and the hierarchical early warning and emergency measures are established in combination with the theory of protection motivation. The present invention integrates various state information of the vehicle to discriminate, increases the accuracy of the detection result, and enhances the safety of assisted driving.

Description

technical field [0001] The invention belongs to the technical field of safe driving detection, and in particular relates to a method and system for identifying abnormal driving behavior based on vehicle state and driver state. Background technique [0002] In recent years, there has been an increasing amount of news about car breakdowns, driver emergencies or interference with driving resulting in multiple casualties. With the rapid growth of the number of private cars and commercial vehicles, the driving state of the vehicle and the state of the driving area are monitored during the driving process, so that it can give an early warning to the driver or take emergency braking to ensure driving when the vehicle is in an abnormal state. The safety of people and passengers is unquestionable. [0003] The driving state of the vehicle can be divided into the driving area state inside the vehicle and the vehicle state outside the vehicle. For the status recognition of the drivin...

AI Technical Summary

Problems solved by technology

However, for the detection of lane lines, detection errors are often caused by blurred lane lines or stains caused by tire wear, and the working conditions of the camera are relatively high. In the case of poor lighting conditions such as night and tunnels, the accuracy of lane line detection results will be reduced. accuracy

[0005] At present, there are many methods for monitoring abnormal driving behavior of vehicles, but most of them monitor a single element, and there are few monitoring systems that integrate driver status and vehicle status

According to the problem that the above-described vehicle abnormal driving behavior monitoring system has a single form of judgment and the detection results are not comprehensive enough, the present invention designs a method and system for identifying abnormal driving behavior based on the state of the vehicle and the state of the driver.

[0006] At present, there is no abnormal driving behavior recognition method and system based on vehicle state and driver state. This method judges vehicle state based on V2X communication, and judges the driving state of the vehicle based on the detection results of the driver state, and establishes a corresponding early warning mechanism based on the detection results. and emergency measures
