Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] Driving distraction is divided into visual distraction, cognitive distraction, auditory distraction, and body movement distraction. Visual distraction and cognitive distraction are two common driving distraction behaviors. The driver will not be able to detect unexpected information of the external environment in time if he leaves the road or has no information about the steering and driving tasks, which will have an important impact on driving safety. Although the driver's line of sight does not deviate from the road when cognitive distraction occurs, due to The driver's attention is not concentrated on the driving task, and the driver will turn a blind eye and cannot respond in time to the dangerous situation outside. The present invention arranges light-emitting diodes in the field of vision in front of the driver to simulate unexpected situation...

Abstract

The invention provides a system for detecting distracted driving behaviors. The system comprises a stimulus information providing device, a single chip microcomputer, a feedback information acquisition device, a driving behavior data acquisition device and a physiological signal acquisition device. The stimulus information providing device is used for providing visual stimulus information by utilizing light emitting diodes arranged along a vehicle front windshield and on the two sides or tactile stimulus information by utilizing a micro vibration motor arranged on a driver body; the single chip microcomputer is used for controlling a driving instruction of the visual or tactile stimulus information; the feedback information acquisition device is used for acquiring the reaction of a driver to the perception of visual stimulus information or vibration stimulus information by utilizing buttons in a left hand and a right hand of the driver; the driving behavior data acquisition device is used for acquiring the information that the driver operates a brake pedal, an accelerator pedal, a clutch, a gear and a steering light as well as the vehicle speed information; the physiological signal acquisition device is used for acquiring electroencephalogram, electrocardiogram, skin conductance, heart rate and pulse information. The system provided by the invention can effectively detect the influence of the distracted driving behaviors on driving safety according to the driver's reaction time, the hit rate and the like.

Description

technical field [0001] The invention belongs to the technical field of driving state monitoring, in particular to the field of driving distraction behavior detection. Background technique [0002] Driving distraction refers to the driving behavior in which the driver's attention is shifted from driving tasks to non-driving tasks, which widely exists in the daily driving process. With the rapid development of information and communication technology and the gradual popularization of information products on vehicles, the driving distraction behavior caused by using mobile phones and in-vehicle information devices is increasing, which affects the timely acquisition and processing of various traffic information by drivers. Road traffic accidents have a major impact on traffic safety. [0003] The current detection methods for driving distraction mainly use the main task measurement method, auxiliary task measurement method, physiological measurement method, and subjective evalu...
