[0053] The embodiment of the present application provides a safety control method based on a driving seat, which is applied to a target vehicle including a seat adjusting system. The seat adjusting system is used for controlling the driving seat of the cockpit of the target vehicle to move forward and backward and left and right. The seat adjusting system includes two layers of vertically arranged guide rails. The first layer of guide rails is used for controlling the driving seat to move in the forward and backward direction (y-axis). The second layer of guide rails is fixed on the first layer of guide rails and is used for controlling the driving seat to move in the left and right direction (x-axis). The driving seat can move in the left and right direction (x-axis) while moving in the forward and backward direction (y-axis).

[0054] More specifically, the driving device can be used to drive the first layer of guide rails and the second layer of guide rails to move, so as to drive the driving seat fixedly arranged on the second layer of guide rails to move.

As shown in the figure, the red device is a cylinder, and the orange device is a hydraulic rod. The cylinder is used to drive the driving seat to move in the y-axis. Figure 1

The method can be executed by the processor of a terminal device when running a corresponding computer program. For the convenience of description, only the parts related to the embodiment are shown. The method provided by the embodiment includes the following steps. Figure 2

[0056] S100: When the cockpit of the target vehicle has a driver and a passenger, it is detected in real time whether there is a target object around the target vehicle.

[0057] Specifically, determining whether the cockpit has a driver and a passenger includes judging whether the main driver seat and the passenger seat have a driver and a passenger.

[0058] ​​In this embodiment, the pressure sensor and the temperature sensor are used to detect whether there is a driver or passenger in the cockpit. Specifically, the real-time temperature is detected by the temperature sensor pre-set in the driver's seat and the front passenger's seat. When the real-time temperature is detected within the pre-set temperature range, it is determined that there is a driver or passenger on the driver's seat or the front passenger's seat. The pre-set temperature range is a temperature range representing the presence of a driver or passenger. For example, the pre-set temperature range can be 35-40°C.

[0059] The real-time pressure is detected by the pressure sensor pre-set in the driver's seat and the front passenger's seat. When the real-time pressure is greater than the pre-set pressure threshold, it is determined that there is a driver or passenger on the driver's seat or the front passenger's seat. The pre-set pressure threshold is the minimum pressure value representing the presence of a driver or passenger. For example, the pre-set pressure threshold can be 210N.

[0060] In this embodiment, when the real-time temperature of the driver's seat or the front passenger's seat is within the pre-set temperature range and the real-time pressure is greater than the pre-set pressure threshold, it is determined that there is a driver or passenger in the cockpit of the target vehicle.

[0061] After there is a driver or passenger in the cockpit of the target vehicle, the vehicle body camera and the radar are used to detect whether there is a target object around the target vehicle in real time. The target object includes moving objects such as other vehicles, animals, etc., and fixed objects such as piers, obstacles, etc. The specific type of target object is not limited in this embodiment.

[0062] S200: If there is a target object, the relative speed between the target object and the target vehicle is obtained.

[0063] The relative speed refers to the relative speed between the target object and the target vehicle. Specifically, it can be the relative speed between the target object and the target vehicle when the target object approaches the target vehicle at a certain speed, or the relative speed between the target object and the target vehicle when the target vehicle approaches the target object at a certain speed, or the relative speed between the target object and the target vehicle when they approach each other at a certain speed. This embodiment does not limit it.

[0064] In this embodiment, the ranging sensor pre-set in the target vehicle can be used to collect the real-time distance between the target object and the target vehicle in real time. According to the difference Δs between the real-time distances collected at adjacent two times and the interval time ΔT between the adjacent two times, the relative speed between the target object and the target vehicle within the interval time is calculated. That is, the real-time speed at which the target object approaches the cockpit of the target vehicle is determined.

[0065] S300: If the relative speed is greater than the pre-set speed threshold, the seat adjustment system is used to control the driver's seat to move to a pre-set position. The pre-set position is a position that increases the activity space of the driver or passenger.

[0066] In this step, after determining the relative speed between the target object and the target vehicle, it is determined whether the relative speed is greater than a preset speed threshold. If the relative speed is greater than the preset speed threshold, it indicates that the driver's cabin of the target vehicle is at risk of collision, and thus the driver's seat is controlled to move to a preset position by the seat adjustment system. Specifically, the driver's seat is controlled to move away from the collision side along the x-axis and to move backward along the y-axis by the seat adjustment system. After the driver's seat is moved to the preset position, the position of the activity space of the driver and passenger is increased.

[0067] In this embodiment, the preset speed threshold can be 0, that is, when there is a relative speed between the target object and the target vehicle, it indicates that the target vehicle is at risk of collision, and thus the driver's seat is controlled to move by the seat adjustment system.

[0068] For the driver's seat, the force state thereof is as shown in FIG. 1. Figure 3 F 红 represents the thrust of the red cylinder on the driver's seat, F 橘 represents the thrust of the orange hydraulic rod on the driver's seat, and F f represents the rolling friction between the driver's seat and the guide rail. When the target vehicle is normally driven, the position of the driver's seat does not change, that is, F 红 =F 橘 +F f ; when the driver's seat needs to be controlled to move, the force state of the driver's seat changes to F 红 >F 橘 +F f , so that the driver's seat moves away from the collision point, thereby providing a larger activity space for the driver and passenger.

[0069] It should be noted that the driver's cabin includes a main driver's seat and a co-driver's seat. In this embodiment, it is further determined that the main driver's seat or the co-driver's seat of the driver's cabin has a driver and passenger. If neither the main driver's seat nor the co-driver's seat has a driver and passenger, the driver's seat does not need to be controlled to move. When only the main driver's seat has a driver and passenger, only the main driver's seat needs to be moved when it is determined that the relative speed is greater than the preset speed threshold. When both the main driver's seat and the co-driver's seat have a driver and passenger, the main driver's seat and the co-driver's seat are simultaneously controlled to move to corresponding preset positions when it is determined that the relative speed is greater than the preset speed threshold.

[0070] The embodiment of the application provides a safety control method based on a vehicle seat, which is applied to a target vehicle comprising a seat adjusting system, and the seat adjusting system is used for controlling a driver seat of a driver cabin of the target vehicle to move forward and backward and left and right; when the driver cabin of the target vehicle exists a driver and passenger, the safety control method is used for determining that the target vehicle exists a collision risk according to a relative speed between a target object and the target vehicle, and when the driver cabin of the target vehicle is subjected to a collision, the driver seat is controlled to move to a preset position in the forward and backward direction and the left and right direction by the seat adjusting system, so as to increase a moving space of the driver and passenger, slow down a collision impact of a deformed vehicle body on the driver and passenger, avoid extrusion contact between the driver and passenger and the deformed vehicle body, and thus guarantee personal safety of the driver and passenger.

[0071] On the basis of the above-mentioned embodiment, the technical solution is further described and optimized in the embodiment, in particular, in the embodiment, the method further comprises:

[0072] obtaining a real-time distance between the target object and the target vehicle;

[0073] if the relative speed is greater than the preset speed threshold, the driver seat is controlled to move to the preset position by the seat adjusting system, comprising:

[0074] if the real-time distance is greater than the preset collision distance threshold and the relative speed is greater than or equal to the first speed threshold, the driver seat is controlled to move to the first preset position at the first speed by the seat adjusting system.

[0075] In the embodiment, the real-time distance refers to a distance between the target object and the target vehicle detected in real time; the real-time distance between the target object and the target vehicle can be collected in real time by using a distance measuring sensor preset in the target vehicle.

[0076] In the embodiment, after the real-time distance between the target object and the target vehicle is obtained, firstly, it is judged whether the real-time distance is greater than the preset collision distance threshold; if the real-time distance is greater than the preset collision distance threshold, it is further judged whether the relative speed is greater than or equal to the first speed threshold; if the relative speed is greater than or equal to the first speed threshold, it indicates that the target vehicle currently exists a high risk of collision, and thus the driver seat is controlled to move to the first preset position at the first speed by the seat adjusting system. The specific value of the first speed is not limited in the embodiment, and the first speed can be determined by controlling the amount of sodium azide (NaN3) released in the cylinder; the more sodium azide (NaN3) is released, the faster the driver seat moves.

[0077] In one specific example, the preset collision distance threshold is 15 cm, and the first speed threshold is 10 m / s; when the real-time distance between the target object and the target vehicle is greater than 15 cm, and the target object continues to approach the target vehicle at a relative speed greater than or equal to 10 m / s, the control seat adjustment system is immediately ignited to release 70 g of sodium azide (NaN3) in the driving cylinder, and the driving cylinder moves the driver's seat to the first preset position.

[0078] In this embodiment, the coordinate origin is set at the rear of the driver's seat, and the first preset position is 45 cm in the x-axis direction from the center of the driver's seat to the coordinate origin of the cockpit, and 45 cm in the y-axis direction from the center of the driver's seat to the coordinate origin of the cockpit.

[0079] According to the method of this embodiment, when the real-time distance is greater than the preset collision distance threshold, and the relative speed is greater than or equal to the first speed threshold, the driver's seat is moved to the first preset position at the first speed by the seat adjustment system, and the corresponding risk avoidance measures are taken for the target vehicle to currently have a high risk of collision, further ensuring the personal safety of the driver and passenger.

[0080] On the basis of the above-mentioned embodiments, the technical solutions are further described and optimized in this embodiment. Specifically, in this embodiment, the method further comprises:

[0081] If the real-time distance is greater than the preset collision distance threshold, and the relative speed is less than the first speed threshold, the driver's seat is moved to the second preset position at the second speed by the seat adjustment system; the second speed is less than the first speed.

[0082] In this embodiment, after obtaining the real-time distance between the target object and the target vehicle, it is first determined whether the real-time distance is greater than the preset collision distance threshold. If the real-time distance is greater than the preset collision distance threshold, it is further determined whether the relative speed is greater than or equal to the first speed threshold. If the relative speed is less than the first speed threshold, it indicates that the target vehicle currently has a medium risk of collision, and therefore the driver's seat is moved to the second preset position at the second speed by the seat adjustment system. The specific value of the second speed is not limited in this embodiment, and can be determined by controlling the amount of sodium azide (NaN3) released in the cylinder. The more sodium azide (NaN3) is released, the faster the driver's seat moves. In this embodiment, the second speed is less than the first speed, indicating that compared to the high risk of collision of the target vehicle, the driver's seat is moved to the second preset position at a lower speed when the target vehicle has a medium risk of collision. In this embodiment, the second preset position has less space for the driver and passenger to move than the first preset position. That is, when the target vehicle has a lower risk of collision, the driver's seat moves at a relatively slower speed and has less additional space.

[0083] In one specific example, the preset collision distance threshold is 15 cm, and the first speed threshold is 10 m / s; when the real-time distance between the target object and the target vehicle is greater than 15 cm, and the target object continues to approach the target vehicle at a relative speed less than 10 m / s, the seat adjustment system is immediately ignited, and the airbag is not popped out. In this embodiment, the second preset position is 60 cm in the x-axis direction from the center of the driver's seat to the coordinate origin of the cockpit, and 60 cm in the y-axis direction from the center of the driver's seat to the coordinate origin of the cockpit.

[0084] According to the method of this embodiment, when the real-time distance is greater than the preset collision distance threshold and the relative speed is less than the first speed threshold, the driver's seat is controlled to move to the second preset position at the second speed by the seat adjustment system, which can execute corresponding risk avoidance measures for different collision risk situations, thereby saving vehicle driving resources.

[0085] On the basis of the above-mentioned embodiments, the technical solutions are further described and optimized in this embodiment. Specifically, in this embodiment, the method further comprises:

[0086] If the real-time distance is less than or equal to the preset collision distance threshold and the relative speed is greater than the second speed threshold, the driver's seat is controlled to move to the first preset position at a third speed by the seat adjustment system; the second speed threshold is less than the first speed threshold, and the third speed is greater than the first speed and the second speed.

[0087] In this embodiment, after obtaining the real-time distance between the target object and the target vehicle, it is first determined whether the real-time distance is greater than the preset collision distance threshold. If the real-time distance is greater than the preset collision distance threshold, it is further determined whether the relative speed is greater than or equal to the second speed threshold. If the relative speed is greater than the second speed threshold, it indicates that the target vehicle currently has a very high risk of collision, and therefore the driver's seat is controlled to move to the first preset position at the third speed by the seat adjustment system.

[0088] The specific value of the second speed threshold is not limited in this embodiment, which can be 0; that is, when the real-time distance is less than or equal to the preset collision distance threshold, as long as the target object is continuously approaching the target vehicle, the driver's seat is controlled to move to the first preset position at the third speed by the seat adjustment system.

[0089] In addition, the specific value of the third speed is also not limited in this embodiment, which can be determined by controlling the amount of sodium azide (NaN3) released in the gas cylinder; the more sodium azide (NaN3) is released, the faster the driver's seat moves. In this embodiment, the third speed is greater than the first speed and the second speed, which means that compared with the high-risk and medium-risk situations of the target vehicle collision, the driver's seat is controlled to move to the first preset position at the fastest speed when the target vehicle has a very high risk of collision.

[0090] In one specific example, the preset collision distance threshold is 15 cm, and the second speed threshold is 0 m / s; when the real-time distance between the target object and the target vehicle is less than or equal to 15 cm, and the target object continues to approach the target vehicle (the relative speed is not 0), the control seat adjustment system is immediately ignited to release 80 g of sodium azide (NaN3) in the driving cylinder, and the driving cylinder moves the driver's seat to the first preset position. In this embodiment, the first preset position is 45 cm in the x-axis direction from the center of the driver's seat to the coordinate origin of the cockpit, and 45 cm in the y-axis direction from the center of the driver's seat to the coordinate origin of the cockpit.

[0091] According to the method of this embodiment, when the real-time distance is less than or equal to the preset collision distance threshold, and the relative speed is greater than the second speed threshold, the driver's seat is moved to the first preset position at a third speed by the seat adjustment system, corresponding risk avoidance measures are taken for the target vehicle currently having a very high risk of collision, and the personal safety of the driver and passengers is further ensured.

[0092] On the basis of the above-mentioned embodiments, the technical solutions are further described and optimized in this embodiment. Specifically, in this embodiment, the method further comprises:

[0093] If the relative speed is less than or equal to the third speed threshold, a corresponding prompt information is generated; the prompt information is used to prompt the driver and passengers that there is a target object around the target vehicle; and the third speed threshold is less than the second speed threshold.

[0094] In this embodiment, after determining the relative speed between the target object and the target vehicle, it is judged whether the relative speed is less than or equal to the third speed threshold; if the relative speed is less than or equal to the third speed threshold, it indicates that the target object pauses to approach the target vehicle, and the target vehicle currently has no collision risk, so the corresponding prompt information is generated and sent to the corresponding prompt device, so as to use the prompt device to issue a corresponding signal to prompt the driver and passengers that there is a target object around the target vehicle but no collision risk.

[0095] The third speed threshold is less than the second speed threshold, and can be close to 0, indicating that the relative speed between the target object and the target vehicle will not cause a collision risk.

[0096] The prompt device includes a buzzer, an indicator light, a voice player, or a display, etc. More specifically, a preset voice signal can be issued through a microphone device on the target vehicle, or the vehicle lights can be controlled to flash at a preset frequency, or corresponding text or images can be displayed on the center control screen or instrument panel to prompt the driver that there is a target object around the target vehicle but no collision risk.

[0097] In a specific example, when the real-time distance between the target object and the target vehicle is greater than 15 cm, or the real-time distance between the target object and the target vehicle is less than or equal to 15 cm, it is determined whether the relative speed between the target object and the target vehicle is less than or equal to 0 m / s; if the relative speed between the target object and the target vehicle is less than 0 m / s, corresponding prompt information is generated and sent to the central control screen, and the central control screen sends corresponding signals to prompt the driver and passengers that there is a target object around the target vehicle at present, but there is no collision risk.

[0098] According to the method of the embodiment, the relative speed less than or equal to the third speed threshold can be prompted, and the driving experience of the driver and passengers can be further improved.

[0099] On the basis of the above-mentioned embodiments, the technical solutions are further described and optimized in the embodiment, specifically, in the embodiment, the method further comprises:

[0100] After detecting the target object, the target door approached by the target object is determined;

[0101] The target door is actively opened according to the real-time distance and the relative speed.

[0102] In the embodiment, after detecting that there is a target object around the target vehicle, the radar preset on the left and right doors is further used to determine the target door approached by the target object, that is, to determine which side door of the target vehicle the collision is likely to occur.

[0103] After the target door is determined, when it is determined that the target vehicle has a collision risk according to the real-time distance and the relative speed, the corresponding target door is actively opened (popped out) so that the driver and passengers can escape more conveniently through the actively opened target door.

[0104] In actual application, if it is determined that the target object approaches from the front of the target vehicle, both sides of the target vehicle are determined as the target door at this time, and therefore both sides of the target vehicle are actively opened.

[0105] According to the method of the embodiment, the target door approached by the target object can be further actively opened, and the driver and passengers can escape through the actively opened target door, further ensuring the personal safety of the driver and passengers.

[0106] On the basis of the above-mentioned embodiments, the technical solutions are further described and optimized in the embodiment, specifically, in the embodiment, the driver seat is moved to the preset position by the seat adjustment system, comprising:

[0107] It is determined whether there is a passenger in the rear seat of the target vehicle;

[0108] If there is a passenger, the driver's seat is controlled by the seat adjustment system to move left and right to a preset position;

[0109] If there is no passenger, the driver's seat is controlled by the seat adjustment system to move forward and backward and left and right to a preset position.

[0110] Specifically, the image of the rear seat can be collected by the in-vehicle camera, and the image of the rear seat is analyzed and recognized to determine whether there is a passenger in the rear seat. If there is a passenger in the rear seat, it means that if the driver's seat moves backward, it will cause harm to the passenger in the rear seat, so the driver's seat cannot be moved backward, so the seat adjustment system controls the driver's seat to move left and right to a preset position, that is, only controls the driver's seat to move in the control x-axis direction, and controls the driver's seat not to move in the y-axis direction. If there is no passenger in the rear seat, it means that the driver's seat can be moved backward, so the seat adjustment system controls the driver's seat to move forward and backward and left and right to a preset position.

[0111] In this embodiment, the way the seat adjustment system controls the driver's seat is determined according to whether there is a passenger in the rear seat of the target vehicle, which avoids the driver's seat being pushed backward to cause harm to the passenger in the rear seat, and further improves the driving experience of the passenger in the rear seat.

[0112] In actual application, in order to further ensure driving safety, the safety device of the target vehicle can be used to further protect the driver and passenger. On the basis of the above-mentioned embodiments, the technical solutions are further described and optimized in this embodiment. Specifically, in this embodiment, the method further comprises:

[0113] If the real-time distance is greater than the preset collision distance threshold, and the relative speed is greater than or equal to the first speed threshold, the doors of the target vehicle are controlled to be unlocked, the target doors are controlled to be actively opened, and the safety airbag is popped out after the driver's seat is moved to the first preset position for the first preset time length;

[0114] If the real-time distance is greater than the preset collision distance threshold, and the relative speed is less than the first speed threshold, the doors of the target vehicle are controlled to be unlocked, the target doors are controlled not to be actively opened, and the safety airbag is not popped out after the driver's seat is moved to the second preset position;

[0115] If the real-time distance is less than or equal to the preset collision distance threshold, and the relative speed is greater than the second speed threshold, the doors of the target vehicle are controlled to be unlocked, the target doors are controlled to be actively opened, and the safety airbag is popped out after the driver's seat is moved to the first preset position for the second preset time length;

[0116] If the relative speed is less than or equal to the third speed threshold, the doors of the target vehicle are controlled to be unlocked but not actively opened, the driver's seat does not need to be controlled to move, and the safety airbag is not popped out.

[0117] In this embodiment, the safety device of the target vehicle is controlled to execute corresponding safety measures for different real-time distances and relative speeds.

[0118] Specifically, if the real-time distance is greater than the preset collision distance threshold, and the relative speed is greater than or equal to the first speed threshold, it indicates that the target vehicle currently has a high risk of collision, and therefore the doors of the target vehicle are unlocked, the target door is actively opened, and the airbag is ejected after the driver's seat is moved to the first preset position for a first preset time. The target door is the door that is determined to be close to the target object after detecting the target object.

[0119] In one specific example, when the real-time distance S > 15 cm (the real-time distance is greater than the preset collision distance threshold), if the target object continues to approach the driver's cabin of the target vehicle at this time, and the relative speed v ≥ 10 m / s (the relative speed is greater than or equal to the first speed threshold); it is determined that the target vehicle currently has a high risk of collision; the doors of the target vehicle are unlocked; the impact side of the target object is detected by the door radar to determine the target door, and the target door is actively opened (popped out); an ignition command is issued to control the ignition device of the driving cylinder of the seat adjustment system to ignite and start, release 70 g of sodium azide (NaN3) in the driving cylinder, ignite within 2 ms, and drive the driving cylinder to move the driver's seat to a first preset position within 20 ms; the first preset position is 45 cm in the x-axis direction from the center of the driver's seat to the coordinate origin of the driver's cabin, and 45 cm in the y-axis direction from the center of the driver's seat to the coordinate origin of the driver's cabin; after the driver's seat is moved for 20 ms (the first preset time), the central control airbag is ejected.

[0120] If the real-time distance is greater than the preset collision distance threshold, and the relative speed is less than the first speed threshold, it indicates that the target vehicle currently has a medium risk of collision, and therefore the doors of the target vehicle are unlocked, the target door is not actively opened, and the airbag is not ejected after the driver's seat is moved to the second preset position.

[0121] In one specific example, when the real-time distance S > 15 cm (the real-time distance is greater than the preset collision distance threshold), if the target object continues to approach the driver's cabin of the target vehicle at this time and v < 10 m / s (the relative speed is less than the first speed threshold), it is determined that the target vehicle currently has a medium risk of collision; the doors of the target vehicle are controlled to be unlocked; the impact side of the target object is detected by the door radar to determine the target door, and the target door is not actively opened (popped out); a firing instruction is issued to control the ignition device of the driving cylinder of the seat adjustment system to be fired and started, 60 g of sodium azide (NaN3) in the driving cylinder is released, ignited within 2 ms, and the driving cylinder moves the driver's seat to a second preset position within 20 ms; the second preset position is that the center of the driver's seat is 60 cm away from the coordinate origin of the driver's cabin in the x-axis direction and 60 cm away from the coordinate origin of the driver's cabin in the y-axis direction; the airbag does not act.

[0122] If the real-time distance is less than or equal to the preset collision distance threshold, and the relative speed is greater than the second speed threshold, it is determined at this time that the target vehicle currently has a very high risk of collision, therefore the doors of the target vehicle are controlled to be unlocked, the target door is actively opened, and the airbag is popped out after the driver's seat moves to the first preset position for a second preset duration.

[0123] In one specific example, when the real-time distance S ≤ 15 cm (the real-time distance is less than or equal to the preset collision distance threshold), if the target object continues to approach the driver's cabin of the target vehicle at any speed (v ≠ 0) at this time, that is, the relative speed is greater than 0 (the second speed threshold), it is determined that the target vehicle currently has a very high risk of collision; therefore the doors of the target vehicle are controlled to be unlocked; the impact side of the target object is detected by the door radar to determine the target door, and the target door is actively opened (popped out); a firing instruction is issued to control the ignition device of the driving cylinder of the seat adjustment system to be fired and started, 80 g of sodium azide (NaN3) in the driving cylinder is released, ignited within 2 ms, and the driving cylinder moves the driver's seat to a first preset position within 20 ms; the first preset position is that the center of the driver's seat is 45 cm away from the coordinate origin of the driver's cabin in the x-axis direction and 45 cm away from the coordinate origin of the driver's cabin in the y-axis direction; the central control airbag is popped out after the driver's seat moves for a second preset duration of 10 ms.

[0124] If the relative speed is less than or equal to the third speed threshold, and at this time whether the real-time distance is greater than the preset collision distance threshold (the real-time distance S > 15 cm) or the real-time distance is less than or equal to the preset collision distance threshold (the real-time distance S ≤ 15 cm), it is determined that the target vehicle currently has no risk of collision; at this time, the doors of the target vehicle are controlled to be unlocked but not actively opened, the driver's seat does not need to be controlled to move, and the airbag does not need to be popped out.

[0125] When the real-time distance S is greater than 15 centimeters (a preset collision distance threshold) or the real-time distance S is less than or equal to 15 centimeters (the preset collision distance threshold), if the target object is temporarily close to the target vehicle (v = 0) at this time (that is, the relative speed is less than or equal to the third speed threshold 0), it is determined that the target vehicle currently has no collision risk; the doors of the target vehicle are controlled to be unlocked but not actively opened; the driver's seat does not need to be controlled to move; corresponding prompt information is generated and sent to the central control screen, and the central control screen sends corresponding signals to prompt the driver and passenger that there is a target object around the target vehicle at present but no collision risk; the airbag is not activated.

[0126] According to the method of the embodiment, on the basis of moving the driver's seat to increase the activity space for the driver and passenger, more safety protection operations can be provided for the driver and passenger by controlling the working modes of the doors and the airbag under different conditions, and the personal safety of the driver and passenger is further ensured.

[0127] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in combination with actual application scenarios. In combination with Figure 4 Another flowchart of the safety control method based on the driver's seat is shown. In the embodiments of the present application, the specific steps of the safety control method based on the driver's seat are as follows:

[0128] It is determined whether the driver's seat or the passenger's seat in the driver's cabin of the target vehicle has a driver and passenger;

[0129] When the driver's cabin of the target vehicle has a driver and passenger, that is, the driver's seat or the passenger's seat has a driver and passenger, it is determined whether the target vehicle has a collision risk according to the vehicle body camera, the radar and the distance measuring sensor; specifically, it is detected in real time whether there is a target object around the target vehicle; if there is a target object, the doors of the target vehicle are controlled to be unlocked;

[0130] The real-time distance and the relative speed between the target object and the target vehicle are obtained;

[0131] According to the real-time distance and the relative speed, a corresponding state relationship is determined, and a corresponding risk avoidance measure is executed according to the state relationship:

[0132] State relationship 1:

[0133] When the real-time distance S is less than or equal to 15 centimeters (a preset collision distance threshold), if the target object continues to approach the driver's cabin of the target vehicle at any speed (v ≠ 0) at this time, that is, the relative speed is greater than 0 (a second speed threshold), it is determined that the target vehicle currently has a very high risk of collision;

[0134] The doors of the target vehicle are controlled to be unlocked;

[0135] The target object is detected by the door radar, the impact side of the target object is determined, the target door is determined, and the target door is actively opened (popped out) by the door radar;

[0136] The ignition device of the driving cylinder of the seat adjustment system is ignited to release 80g of sodium azide (NaN3) in the driving cylinder, which is ignited within 2ms, and the driving cylinder moves the driver's seat to a first preset position within 20ms; the first preset position is 45cm away from the coordinate origin of the cockpit in the x-axis direction and 45cm away from the coordinate origin of the cockpit in the y-axis direction;

[0137] The central safety airbag is popped out 10ms after the driver's seat is moved.

[0138] State relationship 2:

[0139] When the real-time distance S is less than or equal to 15cm (preset collision distance threshold), if the target object is temporarily approaching the target vehicle (v=0) at this time (i.e., the relative speed is less than or equal to the third speed threshold 0), it is determined that the target vehicle currently has no collision risk;

[0140] Control all vehicle doors to be unlocked but not actively opened;

[0141] No need to control the movement of the driver's seat;

[0142] Generate corresponding prompt information and send the prompt information to the central control screen, and issue corresponding signals through the central control screen to prompt the driver and passenger that there is a target object around the target vehicle at present but no collision risk;

[0143] The safety airbag is not activated.

[0144] State relationship 3:

[0145] When the real-time distance S is greater than 15cm (preset collision distance threshold), if the target object is temporarily approaching the target vehicle (v=0) at this time (i.e., the relative speed is less than or equal to the third speed threshold 0), it is determined that the target vehicle currently has no collision risk;

[0146] Control all vehicle doors to be unlocked but not actively opened;

[0147] No need to control the movement of the driver's seat;

[0148] Generate corresponding prompt information and send the prompt information to the central control screen, and issue corresponding signals through the central control screen to prompt the driver and passenger that there is a target object around the target vehicle at present but no collision risk;

[0149] The safety airbag is not activated.

[0150] State relationship 4:

[0151] When the real-time distance S > 15 cm (preset collision distance threshold), if the target object continues to approach the driver's cabin of the target vehicle at this time, and v < 10 m / s (relative speed is less than the first speed threshold), it is determined that the target vehicle currently has a medium risk of collision;

[0152] Control all vehicle doors to be unlocked;

[0153] Determine the target door by detecting the impact side of the target object through the door radar, and the target door is not actively opened (popped out);

[0154] Issue a firing command to control the ignition device of the driving cylinder of the seat adjustment system to fire and start, release 60g of sodium azide (NaN3) in the driving cylinder, ignite within 2ms, and move the driver's seat to a second preset position within 20ms; The second preset position is that the center of the driver's seat is 60 cm away from the coordinate origin of the driver's cabin in the x-axis direction, and 60 cm away from the coordinate origin of the driver's cabin in the y-axis direction;

[0155] The safety airbag is not activated.

[0156] Since the target object is continuously approaching the target vehicle, if the real-time distance S ≤ 15 cm (preset collision distance threshold), the corresponding risk avoidance measures are executed according to state relationship 1;

[0157] State relationship 5:

[0158] When the real-time distance S > 15 cm (preset collision distance threshold), if the target object continues to approach the driver's cabin of the target vehicle at this time, and the relative speed v ≥ 10 m / s (first speed threshold), it is determined that the target vehicle currently has a high risk of collision;

[0159] Control all vehicle doors to be unlocked;

[0160] Determine the target door by detecting the impact side of the target object through the door radar, and the target door is not actively opened (popped out);

[0161] Issue a firing command to control the ignition device of the driving cylinder of the seat adjustment system to fire and start, release 60g of sodium azide (NaN3) in the driving cylinder, ignite within 2ms, and move the driver's seat to a second preset position within 20ms; The second preset position is that the center of the driver's seat is 60 cm away from the coordinate origin of the driver's cabin in the x-axis direction, and 60 cm away from the coordinate origin of the driver's cabin in the y-axis direction;

[0162] After the driver's seat is moved for 20ms, the central safety airbag is popped out.

[0163] It should be noted that when only the driver seat has a driver, the passenger seat has no driver, and it is determined that there is a collision risk, the vehicle doors can be controlled to be unlocked, and only the vehicle door corresponding to the driver seat is actively opened, only the driver seat is moved, and the airbag corresponding to the driver seat is opened; when the driver seat and the passenger seat have drivers, it is determined that there is a collision risk, the vehicle doors are controlled to be unlocked, and the vehicle doors corresponding to the driver seat and the passenger seat are actively opened, and the driver seat and the passenger seat need to be moved at the same time, and the airbags corresponding to the driver seat and the passenger seat are opened; when the driver seat and the passenger seat have no drivers, the corresponding risk avoidance measures do not need to be performed.

[0164] In addition, for the above state relationship 1, state relationship 4 and state relationship 5, it is further determined whether there is a passenger in the rear seat of the target vehicle; if there is a passenger, the driver seat is controlled to move left and right to a preset position through the seat adjustment system, that is, only the driver seat is controlled to move in the control x-axis direction, and the driver seat is not controlled to move in the y-axis direction; if there is no passenger, the corresponding risk avoidance measures are performed.

[0165] The embodiment of the present application provides a safety control method based on a vehicle seat, which is applied to a target vehicle comprising a seat adjustment system, and the seat adjustment system is used for controlling a driver seat of a driver cabin of the target vehicle to move forward and backward and left and right; the method is used for, when there is a driver in the driver cabin of the target vehicle, determining that the target vehicle has a collision risk according to a relative speed and a real-time distance between a target object and the target vehicle, that is, before the driver cabin of the target vehicle is collided, controlling the driver seat to move to a preset position in the forward and backward direction and the left and right direction through the seat adjustment system, and controlling the working mode of the vehicle door and the airbag under different conditions, so as to increase the activity space of the driver, slow down the collision impact of the deformed vehicle body on the driver, avoid the extrusion contact between the driver and the deformed vehicle body, and thus protect the personal safety of the driver.
