[0043] Embodiment 1:

[0044] See also Figure 1 , Figure 1 A flow chart of a vehicle safety control method provided by an embodiment of the present invention, the method comprises the following steps:

[0045] Step 101, receiving eye warning information or gesture warning information from the driver. Then execute step 102

[0046] Specifically, the vehicle includes a vehicle control system and a camera, wherein the camera can be arranged in the vehicle dashboard, and the camera is connected to the vehicle control system in communication. When the driver issues an eye alarm or a gesture alarm, the camera captures an image or video of the eye or gesture and transmits it to the vehicle control system, and the vehicle control system recognizes the eye alarm or gesture alarm through artificial intelligence recognition technology. The camera is arranged in the vehicle dashboard in a relatively concealed manner, and is not easily discovered by passengers, but can fully and effectively recognize the image and video information of the driver's seat.

[0047] The eye alarm information is an eye signal preset in advance by the vehicle owner in the vehicle control system. The eye signal may be a first preset number of consecutive blinks within a first preset time, for example, 5 consecutive blinks within 3 seconds.

[0048] The eye signal may also be moving the eyeball along the first preset trajectory within a second preset time, for example, within 4 seconds, the eyeball moves along the trajectory of moving up, down, left, and right.

[0049] Among them, blinking a first preset number of times continuously within a first preset time is the optimal solution. This action is simple and highly concealed. If the vehicle is in motion, blinking will hardly have any impact on driving safety.

[0050] The gesture alarm information is a gesture signal preset in advance by the vehicle owner in the vehicle control system. The gesture signal may be moving the palm along a first preset trajectory, for example, drawing a circle clockwise with one hand. The gesture signal may also be raising both hands to the head position.

[0051] The gesture signal may also be a first preset gesture, for example, a thumbs-up gesture made by the right hand.

[0052] Among them, raising both hands to the head is the best option. This action is a normal reaction gesture when a person encounters theft, robbery, or coercion. It cooperates with the illegal behavior of the illegal passengers, is concealed, and is not likely to arouse the suspicion of the illegal passengers.

[0053] Step 102 , determining that the vehicle state is a driving state and the vehicle driving speed is less than a first preset speed. Then executing step 103 .

[0054] Specifically, the vehicle control system can detect the vehicle state in real time through the speed sensor, determine whether the vehicle is in a driving state and the vehicle driving speed. When it is detected that the vehicle driving speed is less than the first preset speed, for example, the first preset speed is 30 kilometers per hour, then step 103 is performed. The specific reasons are as follows: if the vehicle is in a high-speed driving state, the vehicle control system controls the driver's seat seat belt buckle to automatically unlock the driver's seat belt, and the illegal passenger will know it immediately, but at this time the vehicle speed is fast, and the driver cannot escape immediately, and the illegal passenger has time to react to control the driver. If the vehicle is in a high-speed driving state, the manual mechanical unlocking seat belt function of the passenger seat seat belt buckle controlled by the vehicle control system fails, and the illegal passenger may immediately know that he is restricted by the seat belt, but at this time the vehicle speed is fast, and the driver cannot escape immediately, and the illegal passenger has time to react, for example, he may use other means, such as knives, lighters, etc. to break the seat belt, and the driver is still unsafe. Therefore, when the vehicle is in a high-speed driving state, the vehicle control system cannot execute step 103 immediately after receiving the eye alarm information or the gesture alarm information, but should execute step 103 when it is determined that the vehicle state is in a driving state and the vehicle driving speed is less than a first preset speed (for example, 30 kilometers per hour). When the vehicle driving speed is less than the first preset speed, the driver can immediately brake suddenly, complete the parking and escape in a very short time, and do not give illegal passengers time to react.

[0055] Step 103: the vehicle control system controls the seat belt buckle at the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle at the passenger seat to disable a manual mechanical unlocking function of the seat belt.

[0056] Specifically, the vehicle control system is in communication connection with the driver's seat belt buckle and / or the passenger's seat belt buckle, and the vehicle control system can send a control instruction to unlock the seat belt to the driver's seat belt buckle, and / or send a control instruction to lock the seat belt to the passenger's seat belt buckle. The driver's seat belt buckle can execute the control instruction to unlock the seat belt and automatically unlock the driver's seat belt, and the passenger's seat belt buckle can execute the control instruction to lock the seat belt and automatically lock the passenger's seat belt, rendering the manual mechanical unlocking function of the passenger's seat belt buckle ineffective. The specific structures of the driver's seat belt buckle and the passenger's seat belt buckle are not limited here, and those skilled in the art can arbitrarily set them according to the functions they implement.

[0057] pass Figure 1According to the vehicle safety control method shown, when the driver encounters theft, robbery or coercion by an illegal passenger, the driver can use artificial intelligence technology to send an alarm message to the vehicle control system through hidden eye signals or gesture signals, which will not alert the illegal passengers. At the same time, after determining that the vehicle is in a driving state and the vehicle speed is less than a first preset speed, the vehicle control system controls the seat belt buckle of the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle of the passenger seat to disable the manual mechanical unlocking of the seat belt. The driver does not need to manually unlock the seat belt, and the illegal passenger is tied to the passenger seat and cannot unlock the seat belt. Most importantly, according to this method, when the vehicle speed is less than the first preset speed, the driver can immediately brake suddenly, complete the parking and escape in a very short time, and do not give the illegal passengers time to react.

[0058] Embodiment 2:

[0059] See also Figure 2 , Figure 2 A flow chart of another vehicle safety control method provided by an embodiment of the present invention, the method comprising the following steps:

[0060] Step 201, receiving eye warning information or gesture warning information from the driver. Then execute step 202

[0061] Step 202: determine that the vehicle is in a driving state and the vehicle speed is less than a first preset speed. Then, steps 203, 204, 205, and 206 are executed.

[0062] Step 203: the vehicle control system controls the seat belt buckle at the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle at the passenger seat to disable a manual mechanical unlocking function of the seat belt.

[0063] Steps 201 to 203 are completely the same as steps 101 to 103 in the first embodiment, and are not described again here.

[0064] In step 204 , the vehicle control system tightens the seat belt of the passenger seat.

[0065] Specifically, the vehicle control system is in communication connection with the seat belt tensioning device for the passenger seat, and the vehicle control system can send a control instruction to tighten the seat belt to the seat belt tensioning device for the passenger seat. The seat belt tensioning device for the passenger seat can execute the control instruction to tighten the seat belt, automatically tighten the seat belt for the passenger seat, thereby tightening and fixing the illegal passenger on the seat to limit his or her movement space. The specific structure of the seat belt tensioning device for the passenger seat is not limited here, and those skilled in the art can arbitrarily set it according to the functions it realizes.

[0066] Step 205: the vehicle control system automatically opens the driver's door.

[0067] Specifically, the vehicle control system is in communication with the driver's door control device, and the vehicle control system can send a control command to the driver's door control device to open the driver's door. The driver's door control device can execute the control command to open the driver's door and automatically open the driver's door, thereby creating an escape condition for the driver.

[0068] Among them, automatically opening the driver's door does not mean automatically opening the door, but includes automatically opening the door and automatically unlocking the door lock but the door is not opened.

[0069] Step 206: the vehicle control system disables the manual door opening function of the passenger seat.

[0070] Specifically, the vehicle control system is in communication connection with the passenger door control device, and the vehicle control system can send a control instruction of disabling the manual door opening function of the passenger seat to the passenger door control device. The passenger door control device can execute the control instruction of disabling the manual door opening function, so that illegal passengers cannot open the door.

[0071] Among them, steps 204, 205, and 206 may all be executed, or only any one or any two thereof may be executed.

[0072] Among them, steps 203, 204, 205, and 206 are executed in no particular order and can be executed simultaneously or in any order.

[0073] pass Figure 2 The vehicle safety control method shown can further tighten and fix the illegal passenger on the seat to limit his or her movement space, automatically open the driver's door, thereby creating escape conditions for the driver, and disable the manual door opening function of the passenger seat, so that the illegal passenger cannot open the door, all of which provide further protection for the driver's safety and escape. Steps 203, 204, 205, and 206 are all executed as the optimal implementation plan, which can provide maximum protection for the driver's safety and escape.

[0074] Embodiment three:

[0075] See also Figure 3 , Figure 3 A flow chart of another vehicle safety control method provided by an embodiment of the present invention, the method comprising the following steps:

[0076] Step 301, receiving eye warning information or gesture warning information sent by the driver. Then, step 302 is executed.

[0077] Step 301 is exactly the same as step 201 in the first embodiment and will not be described again.

[0078] Step 302: display prompt information on the vehicle dashboard. Then execute step 303.

[0079] Specifically, when the vehicle control system recognizes eye warning information or gesture warning information through artificial intelligence recognition technology, in order to avoid false alarms, the vehicle control system will display a prompt message on the vehicle dashboard to remind the driver that the vehicle control system has received the eye warning information or gesture warning information, so that the driver can make subsequent confirmation. For example, the prompt message can be a special symbol light or specific text displayed on the dashboard to remind the driver. Displaying the prompt message on the dashboard is also highly concealed, and only the driver can see it, and illegal passengers are not easy to find it.

[0080] Step 303 , determining that an eye warning message or a gesture warning message sent by the driver is received again within a third preset time after the prompt message is displayed on the vehicle dashboard. Then, step 304 is executed.

[0081] Specifically, after the prompt message is displayed on the vehicle dashboard, if the driver does not make a false alarm within a third preset time, for example, within 10 seconds, and if the driver really wants to send out an alarm message, the driver can send out an eye alarm message or a gesture alarm message again within the third preset time, so that the vehicle control system can confirm that the driver wants to send out an alarm message, thereby avoiding a false alarm. The eye alarm message or gesture alarm message sent out again by the driver can be different from the eye alarm message or gesture alarm message sent out for the first time, but can be a simpler eye signal or gesture signal, so as to reduce the difficulty of interaction between the driver and the vehicle control system.

[0082] Step 304: determine that the vehicle state is a driving state and the vehicle driving speed is less than a first preset speed. Then, steps 305, 306, 307, and 308 are executed.

[0083] Step 305: the vehicle control system controls the seat belt buckle at the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle at the passenger seat to disable a manual mechanical unlocking function of the seat belt.

[0084] In step 306 , the vehicle control system tightens the seat belt of the passenger seat.

[0085] Step 307: The vehicle control system automatically opens the driver's door.

[0086] Step 308: the vehicle control system disables the manual door opening function of the passenger door.

[0087] Steps 305 to 308 are completely the same as steps 203 to 206 in the second embodiment, and will not be described again here.

[0088] pass Figure 3 The vehicle safety control method shown can improve the accuracy of alarms and reduce the problem of false alarms caused by the driver's inadvertent eye movements or gestures.

[0089] Embodiment 4:

[0090] See also Figure 4 , Figure 4 A flow chart of another vehicle safety control method provided by an embodiment of the present invention, the method comprising the following steps:

[0091] Step 401, receiving eye warning information or gesture warning information sent by the driver. Then, step 402 is executed.

[0092] Step 402: display a prompt message on the vehicle dashboard. Then, step 403 is executed.

[0093] Steps 401 to 402 are completely the same as steps 301 to 302 in the third embodiment, and are not described again here.

[0094] Step 403 , determining that an eye warning message or a gesture warning message sent by the driver is received again within a fourth preset time after the prompt message is displayed on the vehicle dashboard. Then, steps 404 and 409 are executed.

[0095] Specifically, after the prompt message is displayed on the vehicle dashboard, if the driver does not make a false alarm within a fourth preset time, for example, within 10 seconds, and if the driver really wants to send out an alarm message, the driver can send out an eye alarm message or a gesture alarm message again within the fourth preset time, so that the vehicle control system can confirm that the driver wants to send out an alarm message, thereby avoiding a false alarm. The eye alarm message or gesture alarm message sent out again by the driver can be different from the eye alarm message or gesture alarm message sent out for the first time, but can be a simpler eye signal or gesture signal, so as to reduce the difficulty of interaction between the driver and the vehicle control system.

[0096] Step 404: determine that the vehicle state is a driving state and the vehicle driving speed is less than a first preset speed. Then, steps 405, 406, 407, and 408 are executed.

[0097] Step 405: the vehicle control system controls the seat belt buckle at the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle at the passenger seat to disable a manual mechanical unlocking function of the seat belt.

[0098] In step 406 , the vehicle control system tightens the seat belt of the passenger seat.

[0099] Step 407: The vehicle control system automatically opens the driver's door.

[0100] Step 408: the vehicle control system disables the manual door opening function of the passenger seat.

[0101] Steps 404 to 408 are completely the same as steps 304 to 308 in the third embodiment, and will not be described again here.

[0102] Step 409: Send an alarm message to the 110 alarm center, wherein the alarm message at least includes the navigation route of the vehicle and / or the location of the vehicle. Then, step 410 is executed.

[0103] Specifically, the vehicle control system sends a message of theft or coercion to the 110 alarm center through the mobile communication network, and at the same time sends the vehicle's navigation route data and / or the vehicle's current location data to the 110 alarm center so that the public security organs can carry out rescue and tracking.

[0104] Step 410, continuously sending the in-vehicle images and / or in-vehicle audio to the 110 alarm center.

[0105] Specifically, after sending an alarm message to the 110 alarm center, the vehicle control system continues to send in-vehicle images and / or in-vehicle audio to the 110 alarm center via the mobile communication network, so that the public security organs can promptly grasp the criminal dynamics of illegal passengers and provide reference information for rescue and tracking.

[0106] In this embodiment, step 409 may also be executed after step 404, and steps 405, 406, 407, 408, and 409 may be executed in any order and may be executed simultaneously or in any order.

[0107] pass Figure 4 The vehicle safety control method shown can covertly help the driver to report to the 110 alarm center, and provide the driving route data, vehicle location information, in-car images, and in-car audio to the 110 alarm center so that the public security organs can carry out rescue and tracking.

[0108] Embodiment five:

[0110] Step 501, receiving eye warning information or gesture warning information sent by the driver. Then, step 402 is executed.

[0111] Step 502: display prompt information on the vehicle dashboard. Then execute step 503.

[0112] Step 503: determine whether an eye warning message or a gesture warning message sent by the driver is received again within the fifth preset time after the prompt message is displayed on the vehicle dashboard. Then, steps 504, 509, and 511 are executed.

[0113] Step 504: determine that the vehicle state is a driving state and the vehicle driving speed is less than a first preset speed. Then, execute steps 505, 506, 507, and 508.

[0114] Step 505: the vehicle control system controls the seat belt buckle at the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle at the passenger seat to disable a manual mechanical unlocking function of the seat belt.

[0115] In step 506 , the vehicle control system tightens the seat belt of the passenger seat.

[0116] Step 507: The vehicle control system automatically opens the driver's door.

[0117] Step 508: the vehicle control system disables the manual door opening function of the passenger door.

[0118] Step 509: Send an alarm message to the 110 alarm center, wherein the alarm message at least includes the navigation route of the vehicle and / or the location of the vehicle. Then, step 510 is executed.

[0119] Step 510: continuously sending the in-vehicle images and / or in-vehicle audio to the 110 alarm center.

[0120] Steps 501 to 510 are completely the same as steps 401 to 410 in the fourth embodiment, and will not be described again here.

[0121] Step 511, determine that the vehicle state is a parking state, and then execute steps 505, 506, 507, and 508.

[0122] Specifically, the vehicle control system can detect the vehicle state in real time through the speed sensor to determine whether the vehicle is in a driving state. When it is detected that the vehicle speed is zero, the vehicle state is determined to be a parking state. In some cases, illegal passengers may also steal, rob, and coerce the driver when the vehicle is in a parking state. At this time, after determining that the vehicle is in a parking state, any one or more of steps 505, 506, 507, and 508 are executed, and the driver can immediately abandon the vehicle and escape, without giving the illegal passengers time to react. In another case, if any one or more of steps 505, 506, 507, and 508 are executed when the vehicle is in a high-speed driving state, the illegal passenger may immediately know that he is restricted by the seat belt, but at this time the vehicle speed is fast, and the driver cannot escape immediately, and the illegal passenger has time to react. For example, other means may be used, such as knives, lighters, etc. to break the seat belt, and the driver is still unsafe. Therefore, when determining that the vehicle state is a parking state, any one or more of steps 505, 506, 507, and 508 are executed, and the driver can immediately abandon the vehicle and escape, without giving the illegal passenger time to react.

[0123] In this embodiment, step 509 may also be executed after step 511, and steps 505, 506, 507, 508, and 509 may be executed in any order and may be executed simultaneously or in any order.

[0124] In this embodiment, steps 502 and 503 may not be executed, but steps 504 , 509 , and 511 may be executed directly after step 501 .

[0125] pass Figure 5 The vehicle safety control method shown in the figure, when it is determined that the vehicle is in a parked state, the vehicle control system automatically unlocks the driver's seat belt, disables the manual mechanical unlocking function of the passenger seat seat belt buckle, tightens the passenger seat seat belt, opens the driver's door, and disables the manual door opening function of the passenger seat door. This method allows the driver to abandon the vehicle and escape immediately, leaving no time for illegal passengers to react.

[0127] See also Figure 6 , Figure 6 A flow chart of another vehicle safety control method provided by an embodiment of the present invention, the method comprising the following steps:

[0128] Step 601, receiving eye warning information or gesture warning information sent by the driver. Then, step 602 is executed.

[0129] Step 602: Display prompt information on the vehicle dashboard. Then execute step 603.

[0130] Step 603: determine whether an eye warning message or a gesture warning message sent by the driver is received again within the sixth preset time after the prompt message is displayed on the vehicle dashboard. Then, steps 605, 606, 607, and 608 are executed.

[0131] Step 605: the vehicle control system controls the seat belt buckle at the driver's seat to automatically unlock the driver's seat belt, and / or the vehicle control system controls the seat belt buckle at the passenger seat to disable a manual mechanical unlocking function of the seat belt.

[0132] In step 606, the vehicle control system tightens the seat belt of the passenger seat.

[0133] Step 607: The vehicle control system automatically opens the driver's door.

[0134] Step 608: the vehicle control system disables the manual door opening function of the passenger door.

[0135] Step 609: Send an alarm message to the 110 alarm center, wherein the alarm message at least includes the navigation route of the vehicle and / or the location of the vehicle. Then, step 610 is executed.

[0136] Step 610: continuously sending the in-vehicle images and / or in-vehicle audio to the 110 alarm center.

[0137] Steps 601 to 610 are completely the same as steps 501 to 510 in the fifth embodiment, and will not be described again.

[0138] In this embodiment, steps 602 and 603 may not be executed, but steps 605 , 606 , 607 , 608 , and 609 may be executed directly after step 601 .

[0139] pass Figure 6 The vehicle safety control method shown uses artificial intelligence technology to send an alarm message to the vehicle control system through hidden eye signals or gesture signals, which will not alert illegal passengers. The vehicle control system immediately automatically unlocks the driver's seat belt, controls the manual mechanical unlocking function of the passenger seat seat belt buckle to fail, tightens the passenger seat seat belt, opens the driver's door, and controls the manual door opening function of the passenger seat to fail. This method can liberate the driver and restrain the criminals in the first time, reducing the possibility of illegal passengers hurting the driver.

[0140] The present invention provides several examples of seat belt buckle devices that can disable the manual mechanical unlocking function of the seat belt buckle and examples of seat belt buckle devices that can automatically unlock the driver's seat belt.

[0141] Embodiment seven:

[0142] See also Figure 7 , 8 , 9, Figure 7 , 8 9 is a schematic diagram of a passenger seat seat belt buckle device. The passenger seat seat belt buckle device includes a seat belt plug 1, a seat belt plug slot 2 located on the seat belt plug 1, a seat belt plug locking port 3 located on the seat belt plug 1, a housing 4, a seat belt unlocking button 5, a seat belt hook 6, a rotating shaft 7 fixed to the housing 4, a locking drive device 8, and a locking member 9.

[0143] The seat belt hook 6 includes a locking portion 61 , a connecting arm 62 , a pressing arm 63 , and a rotating hole 64 .

[0144] The engaging portion 61 is used to be inserted into the seat belt plug slot 2 and engaged therewith, thereby limiting the seat belt plug 1 from being pulled out; the engaging portion 61 is fixedly connected to the connecting arm 62 and is arranged at an angle; the connecting arm 62 is fixedly connected to the pressing arm 63 and is arranged at an angle; the rotating hole 64 is used to install the seat belt hook 6 on the rotating shaft 7 on the housing 4, so that the seat belt hook 6 can rotate around the rotating shaft 7. Furthermore, an elastic member (not shown in the figure) is also arranged between the seat belt buckle 6 and the housing 4, and the elastic member is used to force the engaging portion 61 to rotate relative to the housing 4, and force the engaging portion 61 to move in the direction of being engaged in the seat belt plug slot 2, that is, under the action of the elastic member, the initial position of the seat belt hook 6 is the position where the engaging portion 61 is engaged in the seat belt plug slot 2.

[0145] The outer side of the engaging portion 61 away from the connecting arm 62 is an inclined surface 611, which is arranged at an angle with the direction in which the seat belt plug 1 is inserted into the housing 4 as a whole, and the angle α on the side close to the opening of the housing 4 where the seat belt plug 1 is inserted into the housing 4 is an acute angle (such as Fig. 9 The inclined surface 611 may be a circular arc inclined surface or a straight line inclined surface.

[0146] The locking working principle of the seat belt plug 1 is as follows: when the seat belt plug 1 is inserted from the opening of the shell 4, the seat belt hook 6 can be squeezed in a direction away from the seat belt plug 1 with the help of the inclined surface 611, so that the seat belt plug 1 can be smoothly inserted into the shell 4. When the seat belt plug is inserted to a certain depth and the seat belt plug slot 2 contacts the engaging portion 61, the engaging portion 61 rotates in a direction close to the seat belt plug 1 under the action of the elastic member, so that the engaging portion 61 is engaged in the seat belt plug slot 2 to complete the engagement, thereby locking the seat belt plug 1.

[0147] The seat belt unlocking button 5 has a pressing portion 51 and an unlocking arm 52, and the seat belt unlocking button 5 is installed in the shell 4, wherein the pressing portion 51 is at least partially exposed outside the shell 4, so that the driver and passenger can press the pressing portion 51 to unlock; wherein the unlocking arm 52 is connected to the pressing portion 51, and the unlocking arm 52 is located inside the shell; in the initial position, the unlocking arm 52 is in contact with or close to the pressing arm 63; the unlocking arm 52 is used to move the unlocking arm 52 toward the pressing arm 63 and push the pressing arm 63 to rotate around the rotating axis 7 when the driver and passenger presses the pressing portion 51, and the rotation direction causes the engaging portion 61 to rotate in the direction away from the seat belt plug slot 2.

[0148] The working principle of manual unlocking of the seat belt plug 1: when the driver or passenger presses the pressing part 51, the unlocking arm 52 moves toward the pressing arm 63 of the seat belt hook 6 and pushes the pressing arm 63 to rotate around the rotating axis 7. The rotation direction causes the engaging part 61 to rotate away from the seat belt plug slot 2, thereby disengaging the engaging part 61 from the seat belt plug slot 2 to unlock the seat belt plug 1. When the driver or passenger releases the pressing part 51, under the reaction force of the elastic member, the seat belt hook 6 and the seat belt unlocking button 5 are reset to the initial position.

[0149] The locking driving device 8 is fixedly installed in the housing 4, and the locking driving device 8 is used to drive the locking member 9; the locking member 9 is also located in the housing 4, and is connected to the locking driving device 8. The locking member 9 is specifically in the shape of a rod, and is used to be inserted into the seat belt plug locking port 3 on the seat belt plug 1;

[0150] Preferably, the locking member 9 is a screw with threads, the locking drive device 8 is a high-speed motor, and the locking drive device 8 is threadedly connected to the locking member 9 via threads, and the two form a screw structure.

[0151] The working principle of the automatic locking of the seat belt plug 1 is as follows: the locking drive device 8 drives the locking member 9 to quickly insert into the seat belt plug locking port 3 , thereby making it impossible for the seat belt plug 1 to be pulled out from the housing 4 .

[0152] Furthermore, a vehicle control system is also included, and the vehicle control system is communicatively connected with the locking drive device 8 .

[0153] Furthermore, it also includes a seat belt tightening device, which is communicatively connected to the vehicle control system.

[0154] Furthermore, a camera is arranged in the vehicle dashboard and is connected to the vehicle control system for collecting the driver's eye alarm information or gesture alarm information. The vehicle control system uses artificial intelligence recognition technology to identify the eye alarm information and gesture alarm information. The camera is arranged in the vehicle dashboard and is relatively hidden, and is not easily discovered by passengers, but can fully and effectively identify the image and video information of the driver's seat.

[0155] After receiving the eye alarm information or gesture alarm information from the driver, the vehicle control system sends a control instruction to lock the seat belt to the locking drive device 8. After receiving the above control instruction, the locking drive device 8 immediately drives the locking member 9 to insert into the seat belt plug locking port 3 on the seat belt plug 1. At this time, even if the pressing part 51 is manually pressed, the seat belt plug 1 cannot be pulled out from the housing 4. Further, after receiving the eye alarm information or gesture alarm information from the driver, the vehicle control system can also send a control instruction to tighten the seat belt to the seat belt tightening device. After receiving the above control instruction, the seat belt tightening device immediately tightens the seat belt. Through the passenger seat belt buckle device, when the driver is robbed or coerced by an illegal passenger, the illegal passenger can be tied to the seat with the seat belt. Further, the illegal passenger can be tightened and fixed to the seat by the seat belt tightening device to limit his or her activity space.

[0156] In another embodiment, after the vehicle control system receives the eye warning information or gesture warning information sent by the driver, when it determines that the vehicle state is in the driving state and the vehicle driving speed is less than the first preset speed, it sends a control instruction to lock the seat belt to the locking drive device 8. After receiving the above control instruction, the locking drive device 8 immediately drives the locking member 9 to insert into the seat belt plug locking port 3 on the seat belt plug 1. At this time, even if the pressing portion 51 is manually pressed, the seat belt plug 1 cannot be pulled out from the housing 4. Further, after the vehicle control system receives the eye warning information or gesture warning information sent by the driver, when it determines that the vehicle state is in the driving state and the vehicle driving speed is less than the first preset speed, it can also send a control instruction to tighten the seat belt to the seat belt tightening device. After receiving the above control instruction, the seat belt tightening device immediately tightens the seat belt. If the control instruction to lock the seat belt and / or tighten the seat belt is executed when the vehicle is in a high-speed driving state, the illegal passenger may immediately know that he is restricted by the seat belt, but the vehicle is moving at a high speed at this time and the driver cannot escape immediately. The illegal passenger has time to react. For example, he may use other means, such as knives, lighters, etc. to break the seat belt, and the driver is still not safe. Therefore, when the vehicle is in a high-speed driving state, the vehicle control system does not execute the control instruction to lock the seat belt and / or tighten the seat belt after receiving the eye alarm information or the gesture alarm information. When the vehicle speed drops to the first preset speed, for example, after 30 kilometers per hour, the control instruction to lock the seat belt and / or tighten the seat belt is executed. At this speed, the driver can immediately brake suddenly, stop the car in a very short time, and escape, thereby reducing the reaction time of the illegal passenger.

[0157] In another embodiment, after receiving the eye alarm information or gesture alarm information sent by the driver, the vehicle control system determines that the vehicle state is a parking state, and sends a control instruction to lock the seat belt to the locking drive device 8. After receiving the above control instruction, the locking drive device 8 immediately drives the locking member 9 to insert into the seat belt plug locking port 3 on the seat belt plug 1. At this time, even if the pressing portion 51 is manually pressed, the seat belt plug 1 cannot be pulled out from the housing 4. Further, after receiving the eye alarm information or gesture alarm information sent by the driver, the vehicle control system determines that the vehicle state is a parking state, and can also send a control instruction to tighten the seat belt to the seat belt tightening device. After receiving the above control instruction, the seat belt tightening device immediately tightens the seat belt. In some cases, illegal passengers may also steal, rob, and coerce the driver when the vehicle is in a parking state. At this time, after determining that the vehicle is in a parking state, the control instruction to lock the seat belt and / or the control instruction to tighten the seat belt are executed, and the driver can immediately abandon the vehicle and flee, without giving the illegal passengers time to react. In another situation, if a control instruction to lock the seat belt and / or a control instruction to tighten the seat belt is executed when the vehicle is in a high-speed driving state, the illegal passenger may immediately know that he is restricted by the seat belt, but the vehicle is moving at a high speed at this time and the driver cannot escape immediately. The illegal passenger has time to react. For example, he may use other means, such as knives, lighters, etc. to break the seat belt, and the driver is still not safe. Therefore, when it is determined that the vehicle is in a parked state, a control instruction to lock the seat belt and / or a control instruction to tighten the seat belt is executed. The driver can immediately abandon the vehicle and escape, without giving the illegal passenger time to react.

[0158] The eye alarm information is an eye signal preset in advance by the vehicle owner in the vehicle control system. The eye signal may be a first preset number of consecutive blinks within a first preset time, for example, 5 consecutive blinks within 3 seconds.

[0159] The eye signal may also be moving the eyeball along the first preset trajectory within a second preset time, for example, within 4 seconds, the eyeball moves along the trajectory of moving up, down, left, and right.

[0160] Among them, blinking a first preset number of times continuously within a first preset time is the optimal solution. This action is simple and highly concealed. If the vehicle is in motion, blinking will hardly have any impact on driving safety.

[0161] The gesture alarm information is a gesture signal preset in advance by the vehicle owner in the vehicle control system. The gesture signal may be moving the palm along a first preset trajectory, for example, drawing a circle clockwise with one hand. The gesture signal may also be raising both hands to the head position.

[0162] The gesture signal may also be a first preset gesture, for example, a thumbs-up gesture made by the right hand.

[0163] Among them, raising both hands to the head is the best option. This action is a normal reaction gesture when a person encounters theft, robbery, or coercion. It cooperates with the illegal behavior of the illegal passengers, is concealed, and is not likely to arouse the suspicion of the illegal passengers.

[0170] The working principle of the automatic locking seat belt plug 1 is as follows: the locking drive device 8 drives the locking member 9 to quickly insert into the seat belt unlocking button locking opening 10, so that the seat belt unlocking button 5 cannot be pressed, thereby making the seat belt plug 1 unable to be unlocked.

[0171] This embodiment also includes a vehicle control system, a seat belt tightening device, and a camera arranged in the vehicle dashboard. The connection relationship, working principle, eye alarm information, and gesture alarm information are basically the same as those of the seventh embodiment. Only the difference between the two is explained here. The rest is exactly the same and will not be repeated. The main differences are as follows:

[0172] The vehicle control system sends a control command to lock the seat belt to the locking drive device 8. After receiving the above control command, the locking drive device 8 immediately drives the locking member 9 to be inserted into the seat belt unlocking button locking port 10 on the seat belt unlocking button 5. At this time, the seat belt unlocking button 5 cannot be pressed, so that the seat belt plug 1 cannot be unlocked.

[0173] Embodiment nine:

[0174] See also Fig.11 , 12 , Fig.11 , 12 The schematic diagram of a driver's seat belt buckle device is shown in FIG. The driver's seat belt buckle device includes a seat belt plug 1, a seat belt plug slot 2 located on the seat belt plug 1, a housing 4, a seat belt unlocking button 5, a seat belt hook 6, a rotating shaft 7 fixed to the housing 4, an unlocking drive device 10, a driving member 14 located in the unlocking drive device 10, an unlocking member 11, a sliding groove 12 located on the unlocking member 11, and a hinge structure 13 for relative rotation of the driving member 14 and the unlocking member 11.

[0175] The housing 4 has an opening, and the seat belt plug 1 is used to be inserted into the housing 4 through the opening.

[0176] The seat belt hook 6 includes a locking portion 61 , a connecting arm 62 , a pressing arm 63 , a rotating hole 64 , and a sliding member 65 .

[0177] Among them, the engaging portion 61 is used to be inserted into the seat belt plug slot 2 and engaged therewith, thereby limiting the seat belt plug 1 from being pulled out; the engaging portion 61 is fixedly connected to the connecting arm 62 and is set at an angle; the connecting arm 62 is fixedly connected to the pressing arm 63 and is set at an angle; the pressing arm 63 includes a connecting section 631, the connecting section 631 is fixedly connected to the connecting arm 62 and is set at an angle, and the pressing arm 63 also includes a pressing section 632, the pressing section 632 is fixedly connected to the connecting section 631 and is set at an angle; the rotating hole 64 is used to install the seat belt hook 6 to the rotating shaft 7 on the shell 4, so that the seat belt hook 6 can rotate around the rotating shaft 7. Furthermore, an elastic member (not shown in the figure) is provided between the seat belt buckle 6 and the housing 4, and the elastic member is used to force the engaging portion 61 to rotate relative to the housing 4, and to force the engaging portion 61 to move in the direction of being inserted into the seat belt plug slot 2, that is, under the action of the elastic member, the initial position of the seat belt hook 6 is the position where the engaging portion 61 is inserted into the seat belt plug slot 2; wherein the pressing section 632 has a first end 6321 and a second end 6322, the first end 6321 being an end for being pressed by the seat belt unlocking button 5, and the second end 6322 being connected to the connecting section 631 At one end, the sliding member 65 is located on the pressing arm 63 at a position away from the first end 6321, and the distance between the position of the sliding member 65 and the first end 6321 is a distance that can satisfy the distance that the sliding member 65 slides in the slide groove 12 until the unlocking is completed when the seat belt unlocking button 5 is pressed to unlock (that is, the seat belt unlocking button 5 is pressed to unlock, and the sliding member 65 slides in the slide groove 12 until the entire unlocking process is completed, and the seat belt unlocking button 5 does not interfere with the unlocking member 11). Preferably, the sliding member 65 is located at the position where the pressing section 632 is connected to the connecting section 631.

[0178] The outer side of the engaging portion 61 away from the connecting arm 62 is an inclined surface 611, which is arranged at an angle with the direction in which the seat belt plug 1 is inserted into the housing 4 as a whole, and the angle α on the side close to the opening of the housing 4 where the seat belt plug 1 is inserted into the housing 4 is an acute angle (such as Fig. 9 The inclined surface 611 may be a circular arc inclined surface or a straight line inclined surface.

[0179] The locking working principle of the seat belt plug 1 is as follows: when the seat belt plug 1 is inserted from the opening of the shell 4, the seat belt hook 6 can be squeezed in a direction away from the seat belt plug 1 with the help of the inclined surface 611, so that the seat belt plug 1 can be smoothly inserted into the shell 4. When the seat belt plug is inserted to a certain depth and the seat belt plug slot 2 contacts the engaging portion 61, the engaging portion 61 rotates in a direction close to the seat belt plug 1 under the action of the elastic member, so that the engaging portion 61 is engaged in the seat belt plug slot 2 to complete the engagement, thereby locking the seat belt plug 1.

[0180] The seat belt unlocking button 5 has a pressing portion 51 and an unlocking arm 52, and the seat belt unlocking button 5 is installed in the shell 4, wherein the pressing portion 51 is at least partially exposed from the shell 4, so that the driver and passenger can press the pressing portion 51 to unlock; wherein the unlocking arm 52 is connected to the pressing portion 51, and the unlocking arm 52 is located inside the shell; in the initial position, the unlocking arm 52 is in contact with or close to the pressing arm 63; the unlocking arm 52 is used to move the unlocking arm 52 toward the pressing arm 63 and push the pressing arm 63 to rotate around the rotating axis 7 when the driver and passenger presses the pressing portion 51, and the rotation direction causes the engaging portion 61 to rotate in the direction away from the seat belt plug slot 2.

[0181] The unlocking drive device 10 is fixedly installed in the housing 4 , and is used to drive the unlocking member 11 ; the unlocking member 11 is also located in the housing 4 and connected to the unlocking drive device 10 .

[0182] The unlocking drive device 10 further includes a driving member 14 , and the driving member 14 is hinged to the unlocking member 11 via a hinge structure 13 .

[0183] The unlocking member 11 is provided with a sliding groove 12 , and the sliding member 65 is slidably connected to the sliding groove 12 , thereby achieving a sliding connection between the pressing arm 63 of the safety belt hook 6 and the unlocking member 11 .

[0184] The slide 12 can be a straight slide, such as Fig.11As shown; the slide groove 12 can also be an arc-shaped trajectory with the rotating shaft 7 as the center (as shown in Figure 13 (a)), which can improve the smoothness of manual unlocking; the slide groove 12 can also be a straight slide groove, and the width of the slide groove 12 is greater than the width of the sliding member 65 (as shown in Figure 13 (b)), and the difference between the two widths can satisfy the value of the sliding member 65 sliding in the slide groove 12 until the unlocking is completed when the seat belt unlocking button 5 is pressed to unlock (that is, the seat belt unlocking button 5 is pressed to unlock, and the sliding member 65 slides in the slide groove 12 until the entire unlocking process is completed, which satisfies the value that the sliding member 65 can slide freely in the slide groove 12), which can improve the smoothness of manual unlocking.

[0185] In another embodiment, a sliding member may be provided on the unlocking member 11 , and a sliding groove may be provided on the pressing arm 63 of the seat belt hook 6 , and the sliding member and the sliding groove are slidably connected to achieve a sliding connection between the seat belt hook 6 and the unlocking member 11 .

[0186] Furthermore, the unlocking drive device 10 further includes a drive device, which is connected to the drive member 14 and is used to drive the drive member 14 .

[0187] Preferably, the driving device is a high-speed motor.

[0188] The manual unlocking working principle of the seat belt plug 1 is as follows: when the driver and the passenger press the pressing part 51, the unlocking arm 52 moves toward the pressing arm 63 of the seat belt hook 6 and pushes the pressing arm 63 to rotate around the rotation axis 7. The rotation direction makes the engaging part 61 rotate away from the seat belt plug slot 2, so that the engaging part 61 is disengaged from the seat belt plug slot 2, and the seat belt plug 1 is unlocked. When the pressing arm 63 of the seat belt hook 6 rotates around the rotation axis 7, the sliding member 65 slides in the sliding groove 12. Since the pressing arm 63 of the seat belt hook 6 rotates around the rotation axis 7 during the unlocking process, the driving member 14 and the unlocking member 11 are hinged through the hinge structure 13 in this embodiment, so as to ensure that the pressing arm 63 of the seat belt hook 6 can realize the rotation around the rotation axis 7. When the driver and the passenger release the pressing part 51, the seat belt hook 6 and the seat belt unlocking button 5 are reset to the initial position under the reaction force of the elastic member.

[0189] The working principle of automatic unlocking of the seat belt plug 1 is as follows: the driving device of the unlocking driving device 10 quickly drives the driving member 14 to move downward, the driving member 14 drives the unlocking member 11 to move downward, and the unlocking member 11 drives the pressing arm 63 of the seat belt hook 6 to rotate around the rotation axis 7, and the rotation direction causes the engaging portion 61 to rotate in a direction away from the seat belt plug slot 2, so that the engaging portion 61 is disengaged from the seat belt plug slot 2, and the seat belt plug 1 is unlocked. Since the pressing arm 63 of the seat belt hook 6 rotates around the rotation axis 7 during the unlocking process, the driving member 14 and the unlocking member 11 are hinged through the hinge structure 13 in this embodiment, so as to ensure that the pressing arm 63 of the seat belt hook 6 can realize rotation around the rotation axis 7.

[0190] In this embodiment, the driver's seat belt buckle device has a simple structure, high integration, is not prone to failure, can be manually unlocked and automatically unlocked, and has high flexibility.

[0191] Furthermore, a vehicle control system is also included, and the vehicle control system is communicatively connected with the unlocking drive device 10 .

[0192] Furthermore, a camera is arranged in the vehicle dashboard and is connected to the vehicle control system for collecting the driver's eye alarm information or gesture alarm information. The vehicle control system uses artificial intelligence recognition technology to identify the eye alarm information and gesture alarm information. The camera is arranged in the vehicle dashboard and is relatively hidden, and is not easily discovered by passengers, but can fully and effectively identify the image and video information of the driver's seat.

[0193] After receiving the eye alarm information or gesture alarm information from the driver, the vehicle control system sends a control command to unlock the seat belt to the unlocking drive device 10. After receiving the above control command, the driving device of the unlocking drive device 10 quickly drives the driving member 14 to move downward, and the driving member 14 drives the unlocking member 11 to move downward. The unlocking member 11 drives the pressing arm 63 of the seat belt hook 6 to rotate around the rotating shaft 7, and the rotation direction makes the engaging part 61 rotate in the direction away from the seat belt plug slot 2, so that the engaging part 61 is separated from the seat belt plug slot 2, and the seat belt plug 1 is unlocked. Through the driver's seat belt buckle device, when the driver is stolen or coerced by illegal passengers, the seat belt can be automatically unlocked for the driver without alarming the illegal passengers, so as to buy time for escape.

[0194] In another embodiment, after the vehicle control system receives the eye alarm information or gesture alarm information sent by the driver, when it determines that the vehicle state is in the driving state and the vehicle driving speed is less than the first preset speed, it sends a control instruction to unlock the seat belt to the unlocking drive device 10. After the unlocking drive device 10 receives the above control instruction, the driving device of the unlocking drive device 10 quickly drives the driving member 14 to move downward, the driving member 14 drives the unlocking member 11 to move downward, and the unlocking member 11 drives the pressing arm 63 of the seat belt hook 6 to rotate around the rotating shaft 7. The rotation direction causes the engaging portion 61 to rotate in the direction away from the seat belt plug slot 2, thereby disengaging the engaging portion 61 from the seat belt plug slot 2, thereby unlocking the seat belt plug 1. If a control command to unlock the seat belt is executed when the vehicle is in a high-speed driving state, the illegal passenger will know it immediately. However, the vehicle is moving at a high speed at this time and the driver cannot escape immediately. The illegal passenger has time to react and control the driver. Therefore, when the vehicle is in a high-speed driving state, the vehicle control system will not execute the control command to unlock the seat belt after receiving the eye alarm information or the gesture alarm information. When the vehicle speed drops to the first preset speed, for example, 30 kilometers per hour, the control command to unlock the seat belt is executed. At this speed, the driver can immediately brake suddenly, stop the car in a very short time, and escape, thereby reducing the reaction time of the illegal passenger.

[0195] In another embodiment, after receiving the eye alarm information or gesture alarm information sent by the driver, the vehicle control system determines that the vehicle state is a parking state, and sends a control instruction to unlock the seat belt to the unlocking drive device 10. After receiving the above control instruction, the unlocking drive device 10 quickly drives the driving member 14 to move downward, and the driving member 14 drives the unlocking member 11 to move downward. The unlocking member 11 drives the pressing arm 63 of the seat belt hook 6 to rotate around the rotating shaft 7, and the rotation direction causes the engaging portion 61 to rotate in a direction away from the seat belt plug slot 2, so that the engaging portion 61 is disengaged from the seat belt plug slot 2, and the seat belt plug 1 is unlocked. In some cases, illegal passengers may also steal, rob, and coerce the driver when the vehicle is in a parking state. At this time, after determining that the vehicle is in a parking state, the control instruction to unlock the seat belt is executed, and the driver can immediately abandon the vehicle and flee, without giving the illegal passengers time to react. There is another situation. If the control command to unlock the seat belt is executed when the vehicle is in a high-speed driving state, the illegal passenger will know it immediately, but the vehicle is moving at a high speed at this time and the driver cannot escape immediately. The illegal passenger has time to react and control the driver. Therefore, when it is determined that the vehicle is in a parked state, the control command to unlock the seat belt is executed. The driver can immediately abandon the vehicle and escape, leaving no time for the illegal passenger to react.

[0196] The eye alarm information is an eye signal preset in advance by the vehicle owner in the vehicle control system. The eye signal may be a first preset number of consecutive blinks within a first preset time, for example, 5 consecutive blinks within 3 seconds.

[0197] The eye signal may also be moving the eyeball along the first preset trajectory within a second preset time, for example, within 4 seconds, the eyeball moves along the trajectory of moving up, down, left, and right.

[0198] Among them, blinking a first preset number of times continuously within a first preset time is the optimal solution. This action is simple and highly concealed. If the vehicle is in motion, blinking will hardly have any impact on driving safety.

[0199] The gesture alarm information is a gesture signal preset in advance by the vehicle owner in the vehicle control system. The gesture signal may be moving the palm along a first preset trajectory, for example, drawing a circle clockwise with one hand. The gesture signal may also be raising both hands to the head position.

[0200] The gesture signal may also be a first preset gesture, for example, a thumbs-up gesture made by the right hand.

[0201] Among them, raising both hands to the head is the best option. This action is a normal reaction gesture when a person encounters theft, robbery, or coercion. It cooperates with the illegal behavior of the illegal passengers, is concealed, and is not likely to arouse the suspicion of the illegal passengers.
