Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

Many people in daily life like to make a call, listen to a song and chat with friends when driving. These additional actions sometimes distract the driver too much, causing many unnecessary safety accidents. Therefore, many drivers desire a way to monitor their attention while driving and to remind themselves of driving safety when appropriate.
In the prior art, no method for monitoring safe driving of a driver is specially used for a high-speed intersection.
Therefore, the invention provides a method and a device for monitoring safe driving of an automobile at a highway intersection.
The present invention is directed to systems and methods for limiting driver distraction, such as increasing (e.g., maintaining) driver attention to driving when driving distraction is detected. At least one sensor for determining driver attention to the travel path and an interface module configured to bring the driver's attention back to the travel path may be included. The image capture device may detect an environment surrounding the vehicle. The logic device may determine whether the environment surrounding the vehicle includes foreign object distraction or whether the driver is distracted by inherent distraction. At least one sensor may monitor the driver's distraction behavior. When distraction is determined, the driver may be required to take action. For example, the driver may interact with the driver monitoring system to verify re-attention to driving (e.g., road exit distraction).
In a first aspect, as shown in fig. 1, the present invention provides a method for monitoring safe driving of an automobile at a highway intersection, the method comprising:
step S101, when an automobile is away from a first distance threshold value of a high-speed intersection, detecting the driving state of a driver, and judging whether the driver is in a normal driving state or an attention warning state at present;
step S102, if the driver is in the attention alarming state at present and the automobile is away from the high-speed intersection by a second distance threshold, a reminding measure is executed;
and step S103, if the driver is still in the attention alarming state after the reminding measure is executed, executing an emergency measure.
In specific implementation, a driver can always observe road conditions when driving normally on a road. When the road condition is observed, the head and the sight line area can deflect to different degrees. From the real data it can be analytically derived that before low speed the user's line of sight and facial orientation will first switch continuously and frequently between navigation and straight ahead. This operation is to confirm whether the vehicle is in the lower lane at the front exit and to confirm the distance of the vehicle from the front exit. Then, the user's line of sight and face orientation are continuously and frequently switched between the vehicle mirror and the direct front, accompanied by body control such as turn-on of the turn signal, steering wheel deflection, and vehicle speed reduction. This action is for safe and fast lane change into the exit road.
The first distance threshold is set at the position 40-50 seconds away from the high-speed intersection, and the second distance threshold is set at the position 30-40 seconds away from the high-speed intersection and can be specifically adjusted according to the situation.
In this embodiment, when the vehicle is a first distance threshold from the highway intersection, detecting the driving state of the driver specifically includes:
and detecting the time length of the driver sight line and the number of times of the driver sight line movement within a first time threshold, if the two detections of the time length of the driver sight line and the number of times of the driver sight line movement are both met, the driver is in a normal driving state, and otherwise, the driver enters an attention alarm state.
In specific implementation, the first time threshold is usually 8-10 seconds, and can be specifically adjusted according to the situation.
In this embodiment, the driver sight line duration detection specifically includes:
and detecting whether the sight line of the driver stares at the left side, the right side, the upper side or the lower side exceeds a second time threshold value or not through the camera within the first time threshold value, judging that the sight line duration detection of the driver does not meet the condition, and outputting a negative value.
In particular, in this scenario, the user's center of gravity has changed significantly and is no longer primarily concerned with driving the vehicle. Inappropriate (dangerous) driving behavior actions fall into the following categories: the left look for the right look (looking at the outside of the two side windows for a long time or driving by a rider); lowering the head to pick up the objects. The driver needs to be reminded not to be distracted because of the inattentive attention caused by the improper (dangerous) driving behavior, great risk and easy traffic accidents.
The second time threshold is typically 5-8 seconds, and may be specifically adjusted depending on the situation.
In this embodiment, the detecting the number of times of movement of the driver's sight line specifically includes:
the driving state of the driver is judged by detecting the times of watching the left rearview mirror, the right rearview mirror and the central control navigation screen by the sight of the driver through the camera, and if the watching times of the sight of the driver are less than the time threshold within the first time threshold, the condition that the detection of the movement times of the sight of the driver is not met is judged, and a negative value is output.
In specific implementation, the threshold value of the times is 2-3 times, and can be specifically adjusted according to the situation.
If any one of the following three conditions is met, the attention-inattentive perception alarm is triggered to enter an attention alarm state:
from the position 40-50s before the high-speed intersection to the position 30-40 seconds away from the high-speed intersection, the navigation times of the driver in the sight line are less than or equal to 2 times (the navigation times are 1 time from the other directions), and the left/right rearview mirror times of the driver in the sight line are equal to 0 time;
from the position 40-50s before the high-speed intersection to the position 30-40 s away from the high-speed intersection, the sight of the driver looks at the left rearview mirror and the right area for less than or equal to 2 times. (e.g., 1 time from the front view of the mirror) and the number of times the driver looks at the mirror and navigates is equal to 0. (the right area is the area to the right of the driver, because the infrared camera is installed at the A column position, the eyes and pupils can not be seen when the head of the driver deflects to the right, so that the driver only needs to identify the area to the right of the center control in the vehicle)
From the position 40-50s before the high-speed intersection to the position 30-40 s away from the high-speed intersection, the number of times that the driver looks at the navigation is equal to 1, and the number of times that the driver looks at the left rearview mirror/right area is equal to 1.
In this embodiment, detecting, by the camera, whether the gaze of the driver to the left, right, upper, or lower side exceeds a second time threshold specifically includes:
the pupil position of a driver is detected through an infrared camera arranged at a left column A and a central control navigation position of an automobile cab, the time length of a certain fixed position in the left side, the right side, the upper side or the lower side of the sight of the driver is counted, and whether the time length exceeds a second time threshold value is judged.
In this embodiment, detect the number of times that driver's sight watched left-hand mirror, right-hand mirror and well accuse navigation screen through the camera, specifically include:
the pupil position of a driver is detected through infrared cameras arranged on a column A on the left side of an automobile cockpit and at a central control navigation position, and the times of watching a left rearview mirror, a right rearview mirror and a central control navigation screen by the sight of the driver are counted.
In this embodiment, if the driver is currently in the attention warning state and the vehicle is away from the highway junction by the second distance threshold, the method for performing the reminding measure specifically includes:
reminding a driver of the fact that the front of the driver is the high-speed intersection through voice broadcasting and light alarming.
In this embodiment, if after the reminding measure is executed, the driver is still in the attention warning state, the emergency measure is executed, which specifically includes:
after the reminding measures are executed, the driving state of a driver is detected, and if the driver is still in the attention alarming state, the automobile starts double flashing, slowly decelerates and automatically alarms.
In specific implementation, after a reminding measure is executed, the driving state of a driver is detected, and if the driver is still in an attention alarming state, the driver is likely to be in an abnormal state of the body, such as extreme fatigue, coma, lethargy or sudden diseases; at the moment, the vehicle is controlled to slowly decelerate by accessing the vehicle control system, and the remote control center is automatically alarmed or an emergency rescue hot line is automatically dialed, so that the vehicle can be timely rescued.
In a second aspect, as shown in fig. 2, the present invention provides a device for monitoring safe driving of an automobile at a highway intersection, comprising: the device comprises a detection unit, a reminding unit and an emergency measure unit;
the detection unit is used for detecting the driving state of a driver when the automobile is away from the highway junction by a first distance threshold value and judging that the driver is in a normal driving state or an attention alarm state at present;
the reminding unit is used for executing reminding measures when the driver is in the attention warning state and the automobile is away from the high-speed intersection by a second distance threshold;
