Dangerous driving preventing device and method based on driver behavior ability test

Abstract

The invention discloses a dangerous driving preventing device based on a driver behavior ability test. The dangerous driving preventing device comprises a control module and a detection module. The detection module is used for detecting the response time, from test indicating lamp turning-on to braking, of a driver and sending collected signals to the control module; the control module is used for controlling turning-on of a test indicating lamp and judging whether the behavior ability of the driver is normal or not by carrying out contrastive analysis on the response time, from test indicating lamp turning-on to braking, collected by the detection module and preset time; if the test result shows that the behavior ability of the driver is normal, a vehicle is normally started, and otherwise, the vehicle can not be normally started. According to the dangerous driving preventing device, the control module controls light emitting of the test indicating lamp, the detection module collects the response time, from test indicating lamp turning-on to braking, of the driver and sends the collected information to the control module, the control module judges whether the driver has normal behavior ability or not, and thus the dangerous driving behavior of a driver with abnormal behavior ability can be prevented.

Description

technical field [0001] The invention relates to a device for preventing dangerous driving, in particular to a device for preventing dangerous driving based on a driver's behavior ability test. Background technique [0002] When a person is drunk, sick, emotional or driving for a long time, his judgment and operation ability will be reduced or lost, the reaction time to light and sound stimulation will be prolonged, and the time for instinctive reflex actions will also be prolonged accordingly. The study found that when a driver is in normal physical condition and finds a dangerous situation ahead, it takes only 0.75 seconds from visual perception to stepping on the brake, but the reaction time in the case of drinking, illness, emotional or long-term dangerous driving is average. It takes 1.5 to 2.25 seconds. In this case, people's attention and judgment will be scattered and sluggish; the coordination function between sensory organs and motor organs such as eyes, hands and f...

The study found that when a driver is in normal physical condition and finds a dangerous situation ahead, it takes only 0.75 seconds from visual perception to stepping on the brake, but the reaction time in the case of drinking, illness, emotional or long-term dangerous driving is average. It takes 1.5 to 2.25 seconds. In this case, people's attention and judgment will be scattered and sluggish; the coordination function between sensory organs and motor organs such as eyes, hands and feet will be hindered, and the distance and speed cannot be correctly judged. It is often impossible to control the accelerator, brake and steering system normally, thus affecting the driving safety of motor vehicles

[0003] Therefore, various test devices for testing whether the driver is a person with normal behavior and capacity have emerged at the historic moment, but the existing t
