[0015] As another improvement of the present application, a method for using a vehicle safety warning system based on a multi-source data fusion algorithm comprises the following steps:

[0016] S1, during the driving process of the vehicle, the vehicle condition monitoring unit monitors the vehicle, mainly monitoring the vehicle's tires, engine operating conditions, brake system, transmission mechanism, gearbox, etc. The road situation awareness unit relies on laser radar sensors, cameras and Beidou navigation system to detect vehicles, objects and people on the road. The vehicle driving state monitoring unit monitors the driving state of the vehicle, such as sudden braking, sudden acceleration, random lane changes, random turns, etc. The emotion recognition module monitors the driver's emotions through the emotion detector, such as tension, anger, overexcitement, sadness, etc.;

[0017] S2, the data acquisition module transmits the data monitored in the above steps to the data fusion module, and the data fusion module combines the data of the intelligent traffic fusion module and the multi-vehicle cooperation module and transmits them to the data processing module. The data processing module pre-processes and fuses the collected data, extracts valuable information, and then transmits it to the result analysis module.

The driver's emotions are monitored through the emotion recognition module. During the driving process, oncoming vehicles and rear vehicles can be warned in time according to the driver's status, effectively reducing the harm of human irregular driving behavior to vehicle safety.

[0036] Figure 1-4 A method for using a vehicle safety warning system based on a multi-source data fusion algorithm is shown, comprising the following steps:

[0037] S1, during the driving process of the vehicle, the vehicle condition monitoring unit monitors the vehicle, mainly monitoring the vehicle's tires, engine operating conditions, brake system, transmission mechanism, gearbox, etc. The road situation awareness unit relies on laser radar sensors, cameras and Beidou navigation system to detect vehicles, objects and people on the road. The vehicle driving state monitoring unit monitors the driving state of the vehicle, such as sudden braking, sudden acceleration, random lane changes, random turns, etc. The emotion recognition module monitors the driver's emotions through the emotion detector 2, such as tension, anger, overexcitement, sadness, etc.;

[0038] S2, the data acquisition module transmits the data monitored in the above steps to the data fusion module, and the data fusion module combines the data of the intelligent traffic fusion module and the multi-vehicle cooperation module and transmits them to the data processing module. The data processing module pre-processes and fuses the collected data, extracts valuable information, and then transmits it to the result analysis module. After analysis and processing, the data is transmitted to the risk assessment module, and the early warning prompt module is triggered after the data that is harmful to driving is evaluated;

[0039] S3, after being triggered, the early warning module triggers the vehicle safety intervention module to let the automatic driving takeover module take over the vehicle to prevent the driver from taking wrong measures and putting the vehicle in a more dangerous situation.

[0041] S5, the driving status of the driver is monitored through the facial recognition device 3. When the driver's eyes are not looking forward, or the driver is communicating with the accompanying personnel for a long time, or holding the phone, the facial recognition device 3 triggers the automatic driving takeover module through the early warning prompt module, and also triggers the multi-colored laser spotlight 8 and the LED display screen 13 to send a warning signal to nearby vehicles. When the driver closes his eyes due to fatigue driving, the facial recognition device 3 triggers the early warning prompt module and allows the automatic driving takeover module to intervene, and also starts the sprayer 5 to spray refreshing liquid to the driver to help the driver stay awake.

[0042] The second implementation method:

[0043] Figure 5It is shown that the driver monitor 12 includes a monitoring box 1, and an emotion detector 2 and a facial recognition device 3 are installed on the side wall of the monitoring box 1 facing the driver's seat (the emotion detector 2 and the facial recognition device 3 are both existing technologies, and the specific models are selected according to actual needs, and are not described in detail here), and the emotion detector 2 is electrically connected to the emotion recognition module, and a head-up display projector 4 is installed on the side wall of the monitoring box 1 facing the front windshield (it is an existing technology, and the specific model is selected according to actual needs, and is not described in detail here), and the head-up display projector 4 is electrically connected to the driver warning unit, the upper end of the monitoring box 1 is an inclined structure, and the head-up display projector 4 is parallel to the front windshield, a liquid storage cavity is installed on the inner wall of the lower end of the monitoring box 1, and a refreshing liquid is stored in the liquid storage cavity, and a plurality of sprayers 5 connected to the liquid storage cavity are installed on the side wall of the monitoring box 1 located below the emotion detector 2 and the facial recognition device 3, and the sprayers 5 are electrically connected to the driver warning unit;

[0044] Figure 8 As shown, an open cavity 101 is opened on the side wall of the monitoring box 1 near the front windshield, and a light dispersing member 6 is placed in the middle of the open cavity 101. The light dispersing member 6 is a fan-shaped structure, and the light dispersing member 6 includes a plurality of light-shielding segments 601 and light-transmitting segments 602, and the light-shielding segments 601 and the light-transmitting segments 602 are alternately connected to each other. When the multi-color laser spotlight 8 is triggered, the rays emitted by the multi-color laser spotlight 8 are directed toward the light dispersing member 6, and the light-shielding effect of the light-shielding segment 601 allows the light to be emitted from the light-transmitting segment 602, which can effectively expand the emission area of ​​the light, thereby ensuring that the oncoming vehicles can see clearly;

[0045] Figure 6 , 7As shown, the upper and lower side walls of the light dispersing member 6 close to the sprayer 5 are fixedly connected with connecting frames 7, and the two connecting frames 7 are fixedly connected with multi-colored laser spotlights 8 electrically connected to the early warning prompt module, the inner wall of the open cavity 101 is fixedly connected with an elastic bracket 9 (preferably a polyurethane elastic material, and other materials can also be selected according to actual needs) fixedly connected to the multi-colored laser spotlight 8, and the opening of the open cavity 101 is fixedly connected with a light guide plate 11, the light guide plate 11 includes a plurality of shading plates 1101 and a light guide plate 1102, and the shading plates 1101 and the light guide plates 1102 are alternately connected to each other, the shading plates 1101 block the light, and the light guide plates 1102 allow the light to pass through, so that the light emitted by the multi-colored laser spotlight 8 is in the form of multiple distributed rays in combination with the divergent effect of the light dispersing member 6. The opening 101 is emitted in the form of a light guide plate 11, rather than in the form of a surface, which can effectively prevent the light emitted from the light guide plate 11 from reflecting on the front windshield and affecting the driver's line of sight. The upper and lower inner walls of the opening 101 are equipped with electromagnets 10 electrically connected to the early warning module (this is the prior art, the specific model is selected according to actual needs, and is not described in detail here), and the side wall of the light dispersing member 6 is fixedly inlaid with a permanent magnetic pad 1001 that repels the electromagnet 10. The early warning module allows the two electromagnets 10 to be turned on alternately front and back, and the magnetic force generated by the electromagnet 10 repels the permanent magnetic pad 1001, so that the light dispersing member 6 reciprocates up and down with the elastic bracket 9 as the rotation center, and the light emitted by the colorful laser spotlight 8 floats up and down in turn, thereby enhancing the early warning effect on oncoming vehicles.

[0046] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
