Problems solved by technology

[0003] Existing anti-lock brakes (ABS), brake force distribution (EBD / CBC), brake assist (EBA / BAS / BA), traction control (ASR / TCS / TRC), vehicle stability control (ESP / DSC / VSC), Technologies such as vehicle-mounted anti-collision radar and fatigue driving detection and early warning can guarantee the safety of the driver to a certain extent, but the above-mentioned technologies can only prevent uncontrollable dangers of the vehicle, and rarely pay attention to the driver's line of sight. The driver's dangerous driving behavior cannot be warned in time

Embodiment 1

[0038] Please refer to figure 1 , which is a traffic safety early warning system of the present application, which includes an image acquisition device 1, a vehicle-mounted direction sensor 6, a digital signal processor 2 and a vehicle-mounted alarm device 3, which will be described in detail below.

[0039] The image acquisition device 1 is used to acquire the reflection image data of the driver's eyeball in real time. Such as figure 2 A schematic diagram of the eye reflection image is shown.

[0040] The on-vehicle direction sensor 6 is used for real-time collection of vehicle traveling direction information or / and steering wheel steering angle information.

[0041] The input end of the digital signal processor 2 is connected with the image acquisition device 1 and the vehicle-mounted direction sensor 6 , and the output end is connected with the vehicle-mounted alarm device 3 .

[0042] The digital signal processor 2 is used to obtain the direction that current driving s...

example 1

[0047] Example 1: During high-speed driving, the driver’s line of sight should be fixed on the front of the car. If it is detected from the eyeball reflection image that the current driver’s line of sight is not directly in front for longer than the preset time, the digital signal processor 2 will send a corresponding signal. alarm signal.

example 2

[0048] Example 2: When the vehicle turns the steering wheel while driving, the driver's line of sight should rotate with the rotation of the steering wheel. If it is detected from the eye reflection image that the current driver's line of sight is different from the steering wheel rotation angle by a preset angle, the duration exceeds the preset time. time, the digital signal processor 2 will send a corresponding alarm signal.

Abstract

A driving safety early warning method and system, the system includes an image acquisition device, a vehicle-mounted direction sensor, a digital signal processor, and a vehicle-mounted alarm device, because the application collects vehicle driving direction information or / and steering wheel steering angle information according to the vehicle-mounted direction sensor, and obtains The current driving should pay attention to the direction, and use the image acquisition device to collect the driver's eye reflection image data, extract the reference object information such as the steering wheel, front windshield and rearview mirror image from the eye reflection image, and analyze the information of these reference objects to obtain The driver's current line of sight can judge in real time whether the driver's line of sight is consistent with the current driving direction, and an alarm will be issued in time if it is inconsistent, which can avoid the driver's dangerous driving and ensure driving safety. Correspondingly, the present application also provides a car including the driving safety warning system and a readable storage medium.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a driving safety early warning method and system, a vehicle, and a readable storage medium. Background technique [0002] With the progress of the economy and society, the rapid development of the automobile industry, the increasing number of automobiles, the increasingly busy traffic, the casualties and property losses caused by the increase in automobile accidents have become a social problem that cannot be ignored. Driving safety is of great importance to human beings. Safety is self-evident, and driving safety issues need urgent attention. [0003] Existing anti-lock brakes (ABS), brake force distribution (EBD / CBC), brake assist (EBA / BAS / BA), traction control (ASR / TCS / TRC), vehicle stability control (ESP / DSC / VSC), Technologies such as vehicle-mounted anti-collision radar and fatigue driving detection and early warning can guarantee the safety of the driver to a certai...
