In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the accompanying drawings that need to be used in the descriptions of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only of the present invention. some examples.

Fig. 1 shows a schematic structural diagram of a system provided by an embodiment of the present invention.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

It is understandable that there is currently no effective solution for children crying and making drivers distracted from driving. More children are fixed in the driving position through the safety seat. Or the driver distracts the child by playing pleasant music or video, so as not to cry. But at the same time, the driver is also distracted in the process of driving the vehicle because of the operation of playing music or video while driving, which brings hidden dangers to driving. Bring unstable safety hazards to yourself and other traffic participants.

In order to solve the above problems, the embodiment of the present invention collects the facial expression, pupil data and body posture data of the child on the rear safety seat through the rear camera inside the vehicle cockpit, detects the current behavior state of the child in real time, and judges the current state of the child through the intelligent controller. Mental state, when the child appears irritable, uncomfortable, crying and other behaviors that will distract the driver from driving, the intelligent controller controls the rear display to play the child's favorite video or controls the speaker to play the child's favorite music, while the rear camera The current state of the child is monitored in real time, and the intelligent controller makes corresponding adjustments in real time to ensure that the child does not affect the normal driving behavior of the driver. Reduce the driver's distraction probability during normal driving of the vehicle and improve driving safety.

Fig. 1 shows a schematic flowchart of a method provided by an embodiment of the present invention.

Specifically, a method for preventing children from interfering with driving behavior, the method specifically includes the following steps:

Step 1. When the vehicle power is in the ON position and the rear row detection function is turned on, the rear camera of the vehicle detects and shoots the children in the rear row of child seats, and obtains the detection and shooting data;

Step 2: The intelligent controller analyzes and judges the state of the child according to the detection and shooting data, and adjusts the state of the child through the vehicle entertainment screen and/or the safety seat controller when the state is abnormal.

In the embodiment of the present invention, after the vehicle is powered on, the power mode is in the ON gear, and the rear detection function is turned on at this time, and the rear camera of the vehicle starts to work, collects and monitors the child status of the rear child seat in real time, and obtains detection and shooting data. Input the detection and shooting data to the intelligent controller in real time, and use the detection algorithm (YOLO5 algorithm) inside the intelligent controller to identify the current state of irritability, discomfort, crying, and impatience in children, and make corresponding active adjustments, specifically:

When the intelligent controller judges that the child's facial state and pupil state are tense, the relevant image data will be passed to the intelligent controller for identification and judgment. After the calculation is completed, the intelligent controller will output the command to the rear car entertainment screen. The screen plays cheerful videos and music, while the rear camera detects the changes of the child's face and pupil status in real time, and adjusts the content played in real time to keep the child calm, so as not to affect the driver's normal driving and improve driving safety;

When the intelligent controller judges that the child's facial state and pupil state show fear, it transmits the relevant image data to the intelligent controller for identification and judgment. The screen plays relaxing or parent-child interactive videos and music. At the same time, the rear camera detects the changes in the child's face and pupil status in real time, and adjusts the playback content and interactive content in real time to keep the child calm and improve driving safety;

When the intelligent controller judges that the child's facial state and pupil state display is crying, it will pass the relevant image data to the intelligent controller for identification and judgment. The entertainment screen activates the artificial voice assistant to interact with the child, and the rear camera detects the changes in the state of the child's face and pupils, and adjusts the content of the interaction between the artificial assistant and the child in real time, so that the child does not cry, does not affect the driver's normal driving, and improves driving safety;

When the intelligent controller judges that the child's facial state and pupil state display are active, it will pass the relevant image data to the intelligent controller for identification and judgment. After the calculation is completed, the intelligent controller will output the command to the rear car entertainment screen. The entertainment screen plays a relaxing video, and the safety seat controller adjusts the angle and wrapping degree of the safety seat so that the child is in a comfortable state. In this state, it can do a small swing, which is similar to the state of a children's rocking bed, so that children do not cry, and the rear camera is synchronized to detect the child's behavior status in real time, and the safety seat controller adjusts the pitch angle and sway degree of the safety seat in real time. Until the child returns to calm, the driver can drive with peace of mind and improve driving safety;

When the intelligent controller judges that the child's facial state and pupil state show that there is no behavior such as irritability, discomfort, crying, or impatience, the playback on the car entertainment screen in the rear row will maintain the status quo, and the angle position of the safety seat will be the default state. Considered risk-free and safe to drive.
