Description

Technical Field

[0001] This application relates to the field of intelligent vehicle technology, and in particular to a vehicle seat, seat belt device, control method and related equipment. Background Technology

[0002] As people's living standards improve, cars, as a convenient means of transportation, are increasingly becoming the primary choice for travel, leading to a gradual increase in the number of cars on the road. Consequently, the number of traffic accidents is also rising. According to statistics from traffic safety management departments, 70% of traffic accidents are collisions, seriously threatening the lives of vehicle occupants.

[0003] To reduce the occurrence of car crashes, the common practice is to install sensors such as lidar, millimeter-wave radar, and cameras in vehicles. Utilizing the advantages of different types of sensors, the distance and relative speed of surrounding vehicles and pedestrians are monitored in real time and with high precision during vehicle operation. This allows for accurate assessment of the likelihood of a collision and provides warnings to the driver before a collision occurs, prompting them to take appropriate measures to avoid a crash. Furthermore, the vehicle can also monitor vehicles and pedestrians ahead in real time. If a sudden danger occurs or the distance to vehicles or pedestrians ahead is less than the safe distance, the vehicle, under the control of the MDC (Mobile Data Center), can actively brake to avoid or reduce rear-end collisions and other accidents, thereby improving driving safety.

[0004] However, the purpose of the above methods is to reduce the occurrence of collision accidents. In some environments, even after the driver receives a warning and takes corresponding measures, or after the car actively brakes, a collision may still occur due to insufficient safety distance or other reasons, and the safety of the occupants in the car may still not be adequately guaranteed. Summary of the Invention

[0005] This application provides a vehicle seat, seat belt device, control method, and related equipment to further ensure the safety of occupants.

[0006] The first aspect of this application provides a vehicle seat, comprising: a first track disposed at the bottom of the vehicle's cabin, having a first part and a second part, wherein the first part extends along the front-rear direction of the vehicle, and the second part extends along the left-right direction of the vehicle and is connected to the rear end of the first part; a seat body disposed on the first track; and a first drive mechanism for driving the seat body to move along the first track.

[0007] Therefore, when a frontal collision occurs, the first drive mechanism can drive the seat body to move rearward along the first segment; when a side collision occurs, the first drive mechanism can drive the seat body to move away from the side of the collision along the second segment. This allows the seat body and occupants to be moved away from the collision location in the event of either a frontal or side collision, reducing injury to the occupants and ensuring their safety.

[0008] As one possible implementation of the first aspect, the first part is connected to the left and right ends of the second part respectively.

[0009] Since the left and right ends of the second segment are connected to the first segment and to the rear end of the first segment, after the forward-facing seat body moves along the first segment at one end of the second segment to the other end of the first segment, the seat body will then face backward. This allows the backrest of the seat body to face forward, thus providing protection for the occupants in the event of a frontal collision and preventing injury from foreign objects entering the cabin during the collision.

[0010] One possible implementation of the first aspect includes two seat bodies. This allows for protection of the passengers in both seat bodies in the event of a vehicle collision.

[0011] A second aspect of this application provides a seat belt device, comprising: a seat belt; a second track disposed on the top of the vehicle's cabin, having a third part and a fourth part, wherein the third part extends along the front-rear direction of the vehicle, and the fourth part extends along the left-right direction of the vehicle and is connected to the rear end of the third part; and a second drive mechanism for driving one end of the seat belt to move along the second track.

[0012] Therefore, when the seat body moves along the first track, the second drive mechanism can drive one end of the seat belt to move along the second track, so that the seat belt can restrain the occupant to the seat body and prevent the occupant from falling off the seat body due to inertia when the seat body moves, thus avoiding danger.

[0013] As one possible implementation of the second aspect, the third part is connected to the left and right ends of the fourth part respectively.

[0014] Therefore, when the seat body moves from one end of the first part to the other end of the second part, the second drive mechanism can correspondingly drive one end of the seat belt to move with the seat body to provide protection for the occupant.

[0015] As a possible implementation of the second aspect, it also includes: a retractor, which is fixedly mounted on the seat body, and the other end of the seat belt is connected to the retractor.

[0016] Therefore, when the seat body moves, the other end of the seat belt can move with the seat, thereby improving the protective effect of the seat belt on the occupant.

[0017] As a possible implementation of the second aspect, the third component is mounted on the upper longitudinal beam of the vehicle, and the fourth component is mounted on the rear cross beam. This makes the second track more robust and stable, thereby ensuring the reliability of the seatbelt in protecting the occupants.

[0018] A third aspect of this application provides a control method, comprising: acquiring collision information, the collision information including a predicted collision probability of a vehicle collision, or indication information indicating whether a vehicle collision has occurred; when the collision probability is greater than or equal to a first threshold, or the indication information indicates that a vehicle collision has occurred, issuing a first control command, the first control command being used to control the movement of a first and a second portion of the vehicle's seat body along a first track, wherein the first portion extends along the front-rear direction of the vehicle, and the second portion extends along the left-right direction of the vehicle and is connected to the rear end of the first portion.

[0019] Therefore, when the predicted collision probability is greater than or equal to a first threshold, or when an indication message indicates that a collision has occurred, the seat body can be controlled to move along the first and second segments of the first track. This allows the seat body to be moved away from the collision location when a side collision is imminent or is already occurring, reducing injury to occupants and ensuring their safety.

[0020] As a possible implementation of the third aspect, the indication information indicates that a collision has occurred, specifically that the collision intensity of the collision is greater than a first intensity threshold.

[0021] Therefore, when the collision intensity of a vehicle collision is detected to be greater than the first intensity threshold, and the collision intensity will cause injury to the occupants, the seat body can be controlled to move along the first and second parts of the first track to control the seat body away from the collision position, reduce the injury to the occupants caused by the collision, and protect the life safety of the occupants in the vehicle.

[0022] As a possible implementation of the third aspect, the collision information also includes the predicted collision location of the vehicle; when the collision location is the side of the vehicle, the first control command is specifically used to control the seat body on the corresponding side of the collision to move along the first track to the opposite side of the collision.

[0023] Therefore, when a collision is predicted to occur at the side of the vehicle, the direction of movement of the seat can be controlled based on the predicted collision location. This allows the seat to be moved away from the collision site during a collision, thus reducing injury to the occupants.

[0024] As a possible implementation of the third aspect, it includes two seat bodies; it also includes: acquiring seating information of a passenger sitting on a seat body; and a first control command specifically used to control the seat body with the passenger sitting in the seating information to move along a first track.

[0025] Therefore, it is possible to determine whether there are occupants on the seat body based on the seating information, thereby controlling the movement of the seat body when occupants are seated, reducing the harm to occupants in a collision and improving the efficiency of occupant protection during a collision.

[0026] As a possible implementation of the third aspect, when the collision location is at the front of the vehicle and one of the two seat bodies in the seating information has a passenger seated, the first control command is specifically used to control the seat body with the passenger seated to move along the first track.

[0027] Therefore, in the event of a frontal collision, the seat body with occupants can be moved to the rear of the seat body without occupants, thus protecting the occupants by using the seat body without occupants and preventing foreign objects from hitting the cabin during the frontal collision and causing injury to the occupants.

[0028] As a possible implementation of the third aspect, the collision information also includes the predicted positional relationship between the vehicle and the vehicle in front after the collision; when the positional relationship shows that the vehicle is located under the vehicle in front, the first control command is also used to control the seat body to lower its height.

[0029] Therefore, when it is predicted that the vehicle will be located under the vehicle in front after a collision, the occupants can be lowered by controlling the seat body to reduce their height, thereby preventing the rear of the vehicle in front from hitting the passenger compartment and causing injury to the occupants.

[0030] As a possible implementation of the third aspect, it also includes: when the collision probability is greater than or equal to a first threshold, or when the indication information indicates that the vehicle has collided, issuing a second control command, the second control command being used to control one end of the seat belt to move along the third and fourth parts of the second track, wherein the third part extends along the front-rear direction of the vehicle, and the fourth part extends along the left-right direction of the vehicle and is connected to the rear end of the third part.

[0031] Therefore, when the seat body moves on the first track, one end of the control seat belt moves along the second track, so that the seat belt can restrain and protect the occupant on the seat body during the movement of the seat body, and prevent the occupant from falling off the seat body due to inertia when the seat body moves.

[0032] As a possible implementation of the third aspect, it also includes: issuing a third control command when the collision probability is greater than the second threshold, the third control command being used to control vehicle braking.

[0033] Therefore, by controlling the vehicle's braking to reduce the vehicle's speed, the severity of a collision can be avoided or reduced, thereby minimizing injury to the occupants.

[0034] A fourth aspect of this application provides a controller, comprising: the controller acquiring collision information, wherein the collision prediction information includes a predicted collision probability of a vehicle colliding, or indication information indicating whether a vehicle has collided; when the collision probability is greater than or equal to a first threshold, or the indication information indicates that a vehicle has collided, the controller issues a first control command, the first control command being used to control the seat body of the vehicle to move along a first segment and a second segment along a first track, wherein the first segment extends along the front-rear direction of the vehicle, and the second segment extends along the left-right direction of the vehicle and is connected to the rear end of the first segment.

[0035] Therefore, when the predicted collision probability is greater than or equal to a first threshold, or when an indication message indicates that a collision has occurred, the seat body can be controlled to move along the first and second segments of the first track. This allows the seat body to be moved away from the collision location when a side collision is imminent or is already occurring, reducing injury to occupants and ensuring their safety.

[0036] As a possible implementation of the fourth aspect, the indication information indicates that a collision has occurred, specifically that the collision intensity of the collision is greater than a first intensity threshold.

[0037] Therefore, when the collision intensity of a vehicle collision is detected to be greater than the first intensity threshold, and the collision intensity will cause injury to the occupants, the seat body can be controlled to move along the first and second parts of the first track to control the seat body away from the collision position, reduce the injury to the occupants caused by the collision, and protect the life safety of the occupants in the vehicle.

[0038] As a possible implementation of the fourth aspect, the collision information also includes the predicted collision location of the vehicle; when the collision location is the side of the vehicle, the first control command is specifically used to control the seat body on the corresponding side of the side to move along the first track to the opposite side of the side.

[0039] Therefore, the direction of movement of the seat body can be controlled based on the predicted collision location. This allows the seat body to be moved away from the collision site during a collision, thus reducing injury to the occupants.

[0040] As one possible implementation of the fourth aspect, it includes two seat bodies; it also includes: acquiring seating information of a passenger sitting on a seat body; and a first control command specifically used to control the seat body with the passenger sitting in the seating information to move along a first track.

[0041] Therefore, it is possible to determine whether there are occupants on the seat body based on the seating information, thereby controlling the movement of the seat body when occupants are seated, reducing the harm to occupants in a collision and improving the efficiency of occupant protection during a collision.

[0042] As a possible implementation of the fourth aspect, when the collision location is at the front of the vehicle and one of the two seat bodies in the seating information has a passenger seated, the first control command is specifically used to control the seat body with the passenger seated to move along the first track.

[0043] Therefore, in the event of a frontal collision, the seat body with occupants can be moved to the rear of the seat body without occupants, thus protecting the occupants by using the seat body without occupants and preventing foreign objects from hitting the cabin during the frontal collision and causing injury to the occupants.

[0044] As a possible implementation of the fourth aspect, the collision information also includes the predicted positional relationship between the vehicle and the vehicle in front after the collision; when the positional relationship shows that the vehicle is located under the vehicle in front, the first control command is also used to control the seat body to lower its height.

[0045] Therefore, when it is predicted that the vehicle will be located under the vehicle in front after a collision, the occupants can be lowered by controlling the seat body to reduce their height, thereby preventing the rear of the vehicle in front from hitting the passenger compartment and causing injury to the occupants.

[0046] As a possible implementation of the fourth aspect, it also includes: when the collision probability is greater than or equal to a first threshold, or when the indication information indicates that a collision has occurred, the controller issues a second control command. The second control command is used to control one end of the seat belt to move along the third and fourth parts of the second track, wherein the third part extends along the front-rear direction of the vehicle, and the fourth part extends along the left-right direction of the vehicle and is connected to the rear end of the third part.

[0047] Therefore, when the seat body moves on the first track, one end of the control seat belt moves along the second track, so that the seat belt can restrain and protect the occupant on the seat body during the movement of the seat body, and prevent the occupant from falling off the seat body due to inertia when the seat body moves.

[0048] As a possible implementation of the fourth aspect, it also includes: when the collision probability is greater than the second threshold, the controller issues a third control command, which is used to control the vehicle braking.

[0049] Therefore, by controlling the vehicle's braking to reduce the vehicle's speed, the severity of a collision can be avoided or reduced, thereby minimizing injury to the occupants.

[0050] The fifth aspect of this application provides a vehicle, including any possible implementation of the vehicle seat described in the first aspect.

[0051] Therefore, when a frontal collision occurs, the first drive mechanism can drive the seat body to move rearward along the first segment; when a side collision occurs, the first drive mechanism can drive the seat body to move away from the side of the collision along the second segment. This allows the seat body and occupants to be moved away from the collision location in the event of either a frontal or side collision, reducing injury to the occupants and ensuring their safety.

[0052] As one possible implementation of the fifth aspect, it also includes any possible implementation of the seat belt device in the second aspect.

[0053] Therefore, when the seat body moves along the first track, the second drive mechanism can drive one end of the seat belt to move along the second track, so that the seat belt can restrain the occupant to the seat body and prevent the occupant from falling off the seat body due to inertia when the seat body moves, thus avoiding danger.

[0054] The sixth aspect of this application provides a computing device, including a processor and a memory, the memory storing program instructions, which, when executed by the processor, cause the processor to perform any possible implementation of the control method in the third aspect.

[0055] The seventh aspect of this application provides a computer-readable storage medium having program instructions stored thereon, which, when executed by a computer, cause the computer to perform any possible implementation of the control method in the third aspect.

[0056] The eighth aspect of this application provides a computer program product including program instructions, which, when executed by a computer, cause the computer to perform any possible implementation of the control method in the third aspect.

[0057] These and other aspects of this application will become more apparent in the description of the following embodiments(s). Attached Figure Description

Detailed Implementation

[0077] The terms "first," "second," "third," etc., used in the specification and claims are only used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that, where permissible, a specific order or sequence may be interchanged so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0078] In the following description, the labels of the steps, such as S110, S120, etc., do not necessarily mean that the steps will be executed in this way. The order of the steps can be interchanged or executed simultaneously if permitted.

[0079] The term "comprising" as used in the specification and claims should not be construed as limiting itself to what follows; it does not exclude other steps. Therefore, it should be interpreted as specifying the presence of the mentioned features, elements, steps, or components, but does not exclude the presence or addition of one or more other features, elements, steps, or components, or groups thereof. Thus, the expression "device comprising means A and B" should not be limited to a device consisting solely of components A and B.

[0080] The term "an embodiment" or "an embodiment" as used in this specification means that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in at least one embodiment of the invention. Therefore, the terms "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment, but may refer to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those skilled in the art from this disclosure.

[0081] To protect vehicle occupants in the event of a collision, one approach is to install a seat movement system, along with primary collision sensors on the front bumper and front crossbeams, and secondary collision sensors in the engine compartment. In the event of a minor collision, triggering only the primary collision sensor, the seat movement system moves the seat backward a predetermined distance, allowing the driver to maintain full control of the steering wheel. If the secondary collision sensor is triggered, the system flips the seat backward, aligning the occupant in a supine position to protect their safety and reduce injury from the collision.

[0082] Another approach involves evenly mounting multiple collision sensors at the front and rear of the vehicle, and installing two sets of ejection seats with opposite ejection directions under all seats. When the front collision sensor detects a frontal collision, the ejection seat moves the seat rearward; when the rear collision sensor detects a rearal collision, the ejection seat moves the seat forward. This allows passengers to be moved away from the impact side in the event of a frontal or rearal collision, thus protecting occupants and reducing injury.

[0083] However, these methods do not take into account side collisions and can only handle frontal and rear collisions. In the event of a side collision, neither of these methods can provide effective protection for passengers.

[0084] This application provides an occupant protection scheme, including a vehicle seat, seat belt device, control method and related equipment, which can further protect the safety of occupants.

[0085] First, the relevant structure of a vehicle 10 to which this occupant protection scheme is applied will be introduced.

[0086] Figure 1 This is a schematic diagram showing the relationship between the various parts of the vehicle 10 in an embodiment of this application. For example... Figure 1As shown, in addition to common components such as engines or electric motors, wheels, steering wheels, and transmissions, the vehicle 10 in this embodiment may also include: an MDC (Mobile Data Center) 110, an ACC (Adaptive Cruise Control) system 120, a seat control system 130, a seatbelt control system 140, an airbag control system 150, and various types of sensors 160 such as a LiDAR (Light Detection and Ranging) 161, a Radar (Radio Detection and Ranging) 162, a Camera 163, a pressure sensor 164, and a collision sensor 165. The MDC 110 is an intelligent driving computing platform deployed on the vehicle 10, providing computing power support for intelligent driving. The ACC system 120 is an intelligent automatic control system that coordinates with the anti-lock braking system and the engine control system to appropriately brake the wheels and reduce the engine's output power, ensuring that the vehicle 10 maintains a safe distance from the vehicle in front. The seat control system 130 is used to control the seat 170, the seat belt control system 140 is used to control the seat belt device 180, and the airbag control system 150 is used to control the airbag.

[0087] Figure 2 for Figure 1 A schematic diagram showing the distribution of sensor 160 in the middle. (See diagram below.) Figure 2 As shown, the sensor 160 can be distributed as follows: a lidar 161 is set at the middle of the front side of the vehicle 10, and at the left and right ends of the front side of the vehicle 10. The lidar 161 can detect the distance of static obstacles in front of and to the left and right sides of the vehicle 10.

[0088] A millimeter-wave radar 162 is installed at the center of the front side of the vehicle 10 and at the left and right ends of the front side of the vehicle 10. The millimeter-wave radar 162 can detect the distance and relative speed of obstacles in front of the vehicle 10 and to the left and right sides.

[0089] Three forward-facing cameras 163 are installed at the top of the windshield of the vehicle 10. The three cameras 163 are respectively positioned in the middle and on the left and right ends. The three cameras 163 can be configured as long-range cameras, medium-range cameras and short-range cameras, respectively, to detect the environment at different distances in front of the vehicle 10.

[0090] A camera 163 is installed in the middle of the left and right sides of the top of the car body of vehicle 10 to detect the environment on the left and right sides of vehicle 10.

[0091] Multiple collision sensors 165 are installed on the front bumper, left and right fenders, and left and right front doors of vehicle 10 to detect whether vehicle 10 has been involved in a collision and the intensity of the collision.

[0092] A pressure sensor 164 is installed on each of the driver's and front passenger seats 170 in the front row of the vehicle 10 to detect whether a passenger is seated in the seat 170. Alternatively, data collected by an in-vehicle camera could be used to detect whether a passenger is seated in the seat 170.

[0093] It should be noted that, Figure 2 The sensor 160 distribution shown is for illustrative purposes only and is not intended to limit the embodiments of this application. The sensor 160 can also be configured in other ways, such as arranging different numbers of millimeter-wave radars 162, cameras 163 and / or ultrasonic radars at appropriate positions on the left and right sides and rear of the vehicle 10 to improve the detection capability of the environment around the vehicle 10.

[0094] like Figure 1 As shown, vehicle 10 can use lidar 161, millimeter-wave radar 162, and camera 163 to monitor objects in five directions (front, rear, left, right, and top) around vehicle 10 in real time, and send the monitoring information to MDC 110. MDC 110 can predict the probability and location of a collision based on the monitoring information from sensors 160 such as lidar 161, millimeter-wave radar 162, and camera 163. The specific prediction method will be described in detail later and will not be repeated here.

[0095] Based on the predicted collision probability and collision location, MDC110 can send control commands to ACC system 120, seat control system 130, seat belt control system 140 and airbag control system 150 to control vehicle 10 and devices such as seat 170, seat belt device 180 and airbag to protect the occupants in the cabin.

[0096] The specific structure of the seat 170 in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0097] Figure 3 This is a structural schematic diagram of the seat 170 in an embodiment of this application. Figure 3As shown, the seat 170 in this embodiment includes a first track 171, a seat body 172, and a first drive mechanism 173. The first track 171 is located at the bottom of the vehicle 10's cabin (specifically, on the floor), and has a first segment 171a extending in the front-rear direction of the vehicle 10, and a second segment 171b extending in the left-right direction of the vehicle 10. The second segment 171b is connected to the rear end of the first segment 171a. The seat body 172 is mounted on the first track 171, and the first drive mechanism 173 drives the seat body 172 to move along the first track 171.

[0098] Therefore, when a frontal collision occurs in the vehicle 10, the first drive mechanism 173 can drive the seat body 172 to move rearward along the first segment 171a; when a side collision occurs in the vehicle 10, the first drive mechanism 173 can drive the seat body 172 to move laterally along the second segment 171b to move away from the collision location. This can reduce the injury to occupants caused by collisions and ensure the safety of the occupants.

[0099] like Figure 3 As shown, a first segment 171a is connected to each of the left and right ends of the second segment 171b. The two first segments 171a and the second segment 171b make the first track 171 form a U-shape. The front ends of the two first segments 171a extend to the corresponding positions of the driver's seat and the passenger seat of the vehicle 10, respectively. The second segment 171b is positioned between the front (driver's seat and passenger seat) seat body 172 and the rear seat. There can be two seat bodies 172, one positioned in the driver's seat and the other in the passenger seat position. The seat body 172 is slidably connected to the first track 171 and can move along the first track 171.

[0100] Figure 4 for Figure 3 A schematic diagram of one mode of movement of the seat body 172. (See diagram below.) Figure 4 As shown, the two seat bodies 172 can move backward along the first track 171, thereby moving the occupants on the seat bodies 172 away from the collision position when a collision occurs at the front of the vehicle 10, reducing the injury to the occupants caused by the collision.

[0101] Figure 5 for Figure 3 A schematic diagram of another mode of movement for the main seat 172. (See diagram below.) Figure 5As shown, of the two seat bodies 172, one seat body 172 can be moved along the first track 171 to the rear of the other seat body 172. Since the first track 171 is U-shaped, after the movement, the orientation of the seat body 172 changes from facing forward to facing backward. Therefore, when the vehicle 10 is involved in a side collision, the seat body 172 on that side can be moved to the other side, moving the occupant on the seat body 172 away from the collision point and reducing injury to the occupant. Alternatively, in the event of a frontal collision of the vehicle 10, if only one of the two seat bodies 172 has an occupant, the occupant on the seat body 172 can be moved away from the collision point and positioned with their back to the collision point, further reducing injury to the occupant.

[0102] In some embodiments, a third track (not shown) extending in the front-rear direction may be provided on the upper part of the first split 171a, forming a double-layer track structure with the first track 171. The seat body 172 is disposed on the third track, and the occupant can adjust the position of the seat body 172 on the third track, thereby adjusting the space in front of the seat body 172 after sitting down. At the bottom of the seat body 172, a lifting mechanism for driving the seat body 172 to rise or fall may also be provided, so that the occupant can adjust the height of the seat body 172 as needed.

[0103] In some embodiments, the first drive mechanism 173 may include a rack disposed along a first track 171, a motor disposed on the seat body 172, and a gear disposed on the motor shaft. The gear meshes with the rack, and the rotation of the motor can drive the seat body 172 to move along the first track 171.

[0104] In some embodiments, the first drive mechanism 173 may include a chain disposed along the first track 171 and a sprocket meshing with the chain. The chain is fixedly connected to the seat body 172, and the sprocket is driven to rotate by a motor, thereby moving the chain and the seat body 172 along the first track 171. The first drive mechanism 173 may also be composed of other devices that can drive the seat body 172 to move along the first track 171, and there is no limitation thereto.

[0105] The specific structure of the seat belt device 180 in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0106] Figure 6 This is a partial structural schematic diagram of the seat belt device 180 in an embodiment of this application; Figure 7 This is a schematic diagram of another part of the structure of the seat belt device 180 in an embodiment of this application. Figure 6 , Figure 7As shown, the seat belt device 180 in this embodiment may include: a seat belt 182, a second track 181, and a second drive mechanism 183.

[0107] The second track 181 is located on the top of the passenger compartment of the vehicle 10 and has a third part 181a and a fourth part 181b. The third part 181a extends along the front-rear direction of the vehicle 10, and the fourth part 181b extends along the left-right direction of the vehicle 10 and is connected to the rear end of the third part 181a. The second drive mechanism 183 is used to drive one end of the seat belt 182 to move along the second track 181. Thus, when the seat body 172 moves along the first track 171, the second drive mechanism 183 can drive one end of the seat belt 182 to move along the second track 181, thereby allowing the seat belt 182 to restrain the occupant to the seat body 172 and prevent the occupant from falling off the seat body 172 due to inertia when the seat body 172 moves, thus avoiding danger.

[0108] The left and right ends of the fourth component 181b are each connected to a third component 181a. The two third components 181a and the fourth component 181b make the second track 181 U-shaped. The two third components 181a of the second track 181 can be set on the upper longitudinal beams on the left and right sides of the top of the cockpit, respectively, and the fourth component 181b can be set on the rear crossbeam of the top of the cockpit, so that the second track 181 is more firmly and stably fixed.

[0109] The second drive mechanism 183 may include a movable seat that is slidably connected to the second track 181, and one end of the seat belt 182 is fixedly mounted on the movable seat. The second drive mechanism 183 can drive the movable seat and one end of the seat belt 182 to move along the second track 181 following the seat body 172. The specific driving method can refer to the first drive mechanism and is not limited thereto.

[0110] like Figure 6 As shown, the seat belt device 180 may further include: a retractor 184, a buckle 185, and a locking tongue 186. The retractor 184 is fixedly mounted on one side of the seat body 172, and the other end of the seat belt 182 is disposed within the retractor 184. The retractor 184 can wind up and release the seat belt 182 from the other end of the seat belt 182. The buckle 185 has a through hole through which the seat belt 182 passes, thereby attaching the buckle 185 to the seat belt 182 and achieving a movable connection with it. The locking tongue 186 is located on the other side of the seat body 172, and the buckle 185 can be inserted into the locking tongue 186 for detachable connection, thereby restraining the occupant to the seat body 172.

[0111] In some embodiments, when the seat body 172 moves, the seat belt 182 needs to remain fixed to the occupant contact portion in order to restrain and protect the occupant on the seat body 172.

[0112] Figure 8 This is a schematic diagram illustrating the positional relationship between the first track 171 and the second track 181 in an embodiment of this application. It shows the possible positional relationship between the first track 171 and the second track 181 when viewed from the top of the vehicle 10. Figure 8 As shown, the second track 181 is arranged parallel to the first track 171. Specifically, the first segment 171a is parallel to the third segment 181a, and the second segment 171b is parallel to the fourth segment 181b. The second track 181 is closer to the outer side of the vehicle 10 compared to the first track 171. Therefore, when the seat body 172 moves to... Figure 4 When the position shown is reached, the seat body 172 and the movable seat travel the same distance, and their average speeds can be set to be the same. When the seat body 172 moves to... Figure 5 When the position is shown, the distance traveled by the movable seat is greater than the distance traveled by the seat body 172, and the average speed of the movable seat can be set to be greater than the moving speed of the seat body 172.

[0113] In summary, vehicle 10 monitors its surroundings using sensor 160, and MDC 110 predicts the probability and location of a collision based on the monitoring data from sensor 160. When the probability of a collision exceeds a second threshold, MDC 110 can issue a third control command to ACC system 120, which will then control vehicle 10 to brake, reducing the risk of injury to occupants.

[0114] When the probability of a collision is greater than or equal to a first threshold, where the first threshold is greater than a second threshold, the MDC110 issues a first control command to the seat control system 130. The seat control system 130 then controls the seat body 172 of the seat 170 to move away from the collision location, thereby reducing the risk of injury to the occupant. The MDC110 can also issue a second control command to the seatbelt control system 140, which controls the seatbelt 182 of the seatbelt device 180 to tighten and move synchronously with the seat body 172, ensuring that the seatbelt 182 continues to provide protection to the occupant even as the seat body 172 moves.

[0115] After a collision occurs, the collision sensor 165 can detect the collision intensity of the vehicle 10 and send the collision intensity to the MDC 110. When the collision intensity exceeds the set intensity threshold, the MDC 110 sends a fourth control command to the airbag control system 150, which controls the airbags to deploy to protect the occupants and reduce the injury caused by the collision.

[0116] The control method 100 provided in the embodiments of this application will now be described with reference to the accompanying drawings.

[0117] Figure 9 This is a flowchart illustrating the control method 100 in an embodiment of this application. The control method 100 can be executed by the vehicle 10, MDC 110, in-vehicle electronic devices, in-vehicle computer, etc., or by the chips or processors within the in-vehicle electronic devices, in-vehicle computer, etc. Figure 9 As shown, the flow of the control method 100 in this embodiment may include:

[0118] Step S110: Obtain collision information, which includes the predicted collision probability of vehicle 10, or indication information indicating whether vehicle 10 has collided.

[0119] Step S120: When the collision probability is greater than or equal to the first threshold, or when the indication information indicates that the vehicle 10 has collided, a first control command is issued. The first control command is used to control the seat body 172 of the vehicle 10 to move along the first part 171a and the second part 171b of the first track 171.

[0120] Therefore, when a collision probability is predicted to be greater than or equal to a first threshold, or when an indication message indicates that a collision has occurred in vehicle 10, the seat body 172 can be controlled to move along the first segment 171a and the second segment 171b of the first track 171. Since the first segment 171a extends along the longitudinal direction of vehicle 10, and the second segment 171b extends along the lateral direction of vehicle 10, when a side collision is about to occur or is already happening, the seat body 172 can be controlled to move away from the collision location, reducing injury to occupants and ensuring their safety.

[0121] Specifically, when a side collision occurs in the vehicle 10, for example, the seat body 172 can be moved along the first split 171a to the second split 171b to adjust the position of the seat body 172 in the left and right directions, so that the seat body 172 is away from the side where the collision occurred.

[0122] Alternatively, when a first segment 171a is connected to each end of the second segment 171b, the seat body 172 is moved along the first segment 171a, through the second segment 171b, to the other side of the first segment 171a. This allows the seat body 172 to move away from the collision location while simultaneously changing its orientation from forward to rearward, thus directing the occupant's legs backward and away from the collision location.

[0123] Alternatively, in the event of a frontal collision with the vehicle 10, the control seat body 172 can move along the first segment 171a, through the second segment 171b, and onto the other side of the first segment 171a. This allows the control seat body 172 to move away from the collision site while simultaneously changing its orientation from forward to rearward, thereby providing protection for the occupants and preventing injury from foreign objects entering the cabin from the front of the vehicle 10.

[0124] In some embodiments, the indication information indicating that the vehicle 10 has been involved in a collision specifically means that the collision intensity of the vehicle is greater than a first intensity threshold.

[0125] Therefore, if the collision intensity of the vehicle 10 is detected to be greater than the first intensity threshold, and the collision intensity will cause injury to the occupants, the seat body 172 can be controlled to move along the first part 171a and the second part 171b of the first track 171 to control the seat body 172 away from the collision position, reduce the injury to the occupants caused by the collision accident, and ensure the life safety of the occupants in the vehicle.

[0126] In some embodiments, the collision information further includes the predicted collision location of the vehicle 10; when the collision location is the side of the vehicle 10, the first control command is specifically used to control the seat body 172 on the corresponding side of the collision to move along the first track 171 to the opposite side of the collision. For example, when the collision location is the left side of the vehicle 10, the left (driver's seat) seat body 172 is controlled to move along the first track 171 to the rear side of the right (passenger seat) seat body 172.

[0127] Therefore, when the collision location is predicted to be the side of vehicle 10, the direction of movement of the seat body 172 can be controlled according to the predicted collision location. Thus, when a collision occurs, the seat body 172 can be controlled to move away from the collision location, thereby reducing injury to the occupants in a collision accident.

[0128] In some embodiments, when two seat bodies 172 are included, the control method 100 further includes: acquiring seating information of a passenger sitting on a seat body 172; a first control command is specifically used to control the seat body 172 in which the passenger is sitting in the seating information to move along a first track 171.

[0129] Therefore, it is possible to determine whether there are occupants on the seat body 172 based on the seating information, thereby controlling the movement of the seat body 172 when occupants are seated, so as to reduce the injury to occupants in a collision and improve the protection efficiency of occupants in the event of a collision.

[0130] In some embodiments, when the collision location is the front of the vehicle 10 and one of the two seat bodies 172 in the seating information has a passenger seated, the first control command is specifically used to control the seat body 172 with the passenger seated to move along the first track 171.

[0131] Therefore, when a collision occurs at the front of the vehicle 10, the seat body 172 with occupants can be moved to the rear of the seat body 172 without occupants, thereby protecting the occupants through the seat body 172 without occupants and preventing foreign objects from hitting the cabin due to the front collision and causing injury to the occupants.

[0132] In some embodiments, the collision information also includes the predicted positional relationship between vehicle 10 and the vehicle in front after the collision; when the positional relationship shows that vehicle 10 is located at the bottom of the vehicle in front, the first control command is also used to control the seat body 172 to lower its height.

[0133] Therefore, when it is predicted that the vehicle 10 will be located under the front vehicle after a collision, the occupants can be lowered by controlling the seat body 172 to avoid the rear of the front vehicle from hitting the cabin and causing injury to the occupants.

[0134] In some embodiments, the control method 100 further includes: issuing a second control command when the collision probability is greater than or equal to a first threshold, or when an indication message indicates that a collision has occurred, the second control command being used to control one end of the seat belt 182 to move along the third part 181a and the fourth part 181b of the second track 181, wherein the third part 181a extends along the front-rear direction of the vehicle 10, and the fourth part 181b extends along the left-right direction of the vehicle 10 and is connected to the rear end of the third part 181a.

[0135] Therefore, when the seat body 172 moves on the first track 171, one end of the control seat belt 182 moves along the second track 181, so that the seat belt 182 can restrain and protect the occupant on the seat body 172 during the movement of the seat body 172, and prevent the occupant from falling off the seat body 172 due to inertia when the seat body 172 moves.

[0136] In some embodiments, the second control command is also used to control the tightening of the seat belt 182.

[0137] Therefore, by tightening the seat belt 182, the occupant can be restrained to the seat body 172, thereby preventing the occupant from falling off the seat and avoiding danger.

[0138] In some embodiments, the control method 100 further includes: issuing a third control command when the collision probability is greater than a second threshold, the third control command being used to control the braking of the vehicle 10.

[0139] Therefore, by controlling the braking of vehicle 10 to reduce the speed of vehicle 10, the severity of the collision accident can be avoided or reduced, thereby reducing the injury to the occupants.

[0140] The controller in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0141] Figure 10 This is a schematic diagram of the controller 190 in an embodiment of this application. Figure 10 As shown, the controller 190 in this embodiment includes: the controller 190 acquires collision information, which includes a predicted collision probability of the vehicle 10, or indication information indicating whether the vehicle 10 has collided; when the collision probability is greater than or equal to a first threshold, or when the indication information indicates that the vehicle has collided, the controller 190 issues a first control command, which is used to control the seat body 172 of the vehicle 10 to move along the first part 171a and the second part 171b of the first track 171.

[0142] Therefore, when the predicted collision probability is greater than or equal to a first threshold, or when the indication information indicates that a collision has occurred, the seat body 172 can be controlled to move along the first segment 171a and the second segment 171b of the first track 171. This allows the seat body 172 to be moved away from the collision location when a collision is about to occur on the side of the vehicle 10 or is already happening, reducing the injury to the occupants and ensuring their safety.

[0143] The functions of controller 190 can be implemented by a processor executing a program (software), or by hardware such as LSI (Large Scale Integration) and ASIC (Application Specific Integrated Circuit), or by a combination of software and hardware.

[0144] Using the controller 190 of this embodiment, it is possible to obtain the reference... Figure 8 The same technical effects are described in the embodiments described herein, and will not be repeated here.

[0145] Below, in conjunction with specific scenarios, this application embodiment also provides an occupant protection method.

[0146] Figure 11This diagram illustrates a scenario where the front of vehicle 10 collides with another vehicle, as described in this application. It provides a possible scenario for a frontal collision involving vehicle 10. Figure 11 As shown, vehicle 10 is following vehicle 20 on the road. When vehicle 20 brakes suddenly to yield to pedestrians, vehicle 10 may collide with vehicle 20 in front of it because the distance between vehicle 10 and vehicle 20 is too close.

[0147] Figure 12 This is a scenario diagram of a side collision involving a vehicle 10 according to an embodiment of this application, providing a possible scenario where a vehicle 10 experiences a side collision while in motion. Figure 12 As shown, when vehicle 10 is traveling straight on the road and passes through an intersection without traffic lights, if vehicle 20 enters from the left side of the intersection and turns left to travel in the same direction as vehicle 10, and neither vehicle 10 nor vehicle 20 avoids the collision by braking or steering, vehicle 20 may hit the side of vehicle 10, resulting in a collision accident.

[0148] Figure 13 This is a scenario diagram illustrating another side collision of vehicle 10 in an embodiment of this application, providing a possible scenario where vehicle 10 is parked in a roadside parking space and experiences a side collision. For example... Figure 13 As shown, vehicle 10 is parked in a roadside parking space. When vehicle 20 is passing through this section of road, it encounters a pedestrian suddenly crossing the road. To avoid the pedestrian, vehicle 20 makes an emergency turn to change lanes. However, due to the excessive weight of vehicle 20, it overturns while turning, potentially colliding with or crushing the side of vehicle 10, thus causing a collision.

[0149] Figure 14a This is a partial flowchart of an occupant protection method performed by vehicle 10 in an embodiment of this application; Figure 14b This is another part of the flowchart of an occupant protection method performed by vehicle 10 in an embodiment of this application. Figure 14a , Figure 14b As shown, in order to protect the occupants of the vehicle 10 and reduce the injury to the occupants in a collision, the specific process of the occupant protection method in this embodiment includes:

[0150] Step S201: Obtain passenger seating information.

[0151] When an occupant sits down, the pressure sensor 164 located on the seat 170 can detect whether the occupant has sat down based on the pressure change of the seat 170. At the same time, the pressure sensor 164 can also send the occupant's seating information to the MDC 110.

[0152] Step S202: Obtain environmental monitoring information around vehicle 10.

[0153] Vehicle 10 can detect the environment around it by using sensors 160 such as lidar 161, millimeter-wave radar 162, and camera 163 located at different positions on vehicle 10, and send the detected data to MDC 110.

[0154] Step S203: Predict the collision probability and collision location.

[0155] MDC110 can process the data detected by sensor 160 to determine the distance L1 between vehicle 10 and other vehicle 20, and the relative speed V between vehicle 10 and other vehicle 20. MDC110 can also determine the braking distance S of vehicle 10 at a speed of 100 km / h based on road friction and the braking performance of vehicle 10. Therefore, MDC110 can calculate:

[0156] Safe braking distance

[0157] The probability of vehicle 10 colliding with vehicle 20

[0158] In addition, the MDC110 can determine the collision location when vehicle 10 collides with other vehicle 20 based on the driving direction and position of vehicle 10 and other vehicle 20. The collision location may be the front or left and right sides of vehicle 10.

[0159] The MDC110 can also determine the positional relationship between vehicle 10 and vehicle 20 after a collision based on the shape and other data of vehicle 20. For example, if vehicle 10 rear-ends vehicle 20, and vehicle 20 is a high-chassis vehicle such as a cement truck or a large truck, vehicle 10 may be positioned below vehicle 20 after the collision. Alternatively, if vehicle 20 is a bicycle, vehicle 10 may be positioned above vehicle 20.

[0160] Step S204: Determine whether the collision probability is greater than or equal to the first threshold.

[0161] When the probability H of a collision between vehicle 10 and another vehicle 20 is greater than or equal to a first threshold, such as greater than or equal to 60%, MDC110 can determine that the collision will cause injury to the occupants and needs to control the movement of the seat body 172 to reduce the injury to the occupants from the collision.

[0162] When the probability H of a collision between vehicle 10 and another vehicle 20 is greater than the second threshold, such as greater than 5% or 10%, but less than the first threshold, MDC110 can determine that the collision will not cause harm to the occupants and there is no need to move the seat body 172.

[0163] Step S205: Determine whether the collision location is the front of vehicle 10.

[0164] When the collision occurs at the front of vehicle 10, the seat body 172 needs to be moved backward to reduce the injury to the occupants from the collision.

[0165] When the collision occurs on the left or right side, the seat body 172 needs to be moved to the opposite side to reduce the injury to the occupants.

[0166] Step S206: Determine whether there is a passenger on the main body 172 of the passenger seat.

[0167] When the occupant seating information shows that there are occupants seated in both the driver's seat and the passenger seat, it is necessary to control the simultaneous movement of the driver's seat and the passenger seat 172 to reduce the injury to the occupants in the driver's seat and the passenger seat in a collision.

[0168] When the occupant seating information shows that only the driver's seat body 172 has an occupant seated, it is only necessary to control the movement of the driver's seat body 172 to reduce the injury to the driver's seat occupant in a collision.

[0169] Step S207: Control the driver's seat and passenger seat body 172 to move backward.

[0170] When the occupant seating information shows that there are occupants seated in both the driver's seat and the passenger seat, the MDC110 can control the seat control system 130 to move the seat bodies 172 of both the driver's seat and the passenger seat backward along the first section 171a of the first track 171, so that the occupants in the driver's seat and the passenger seat can move away from the collision location, thereby reducing the injury to the occupants in the driver's seat and the passenger seat in the event of a frontal collision of the vehicle 10.

[0171] Step S208: Control the driver's seat body 172 to move to the rear of the passenger seat body 172.

[0172] When only the driver's seat 172 is occupied according to the occupant seating information, the MDC110 can control the driver's seat 172 to move along the first track 171 to the rear of the passenger seat 172 via the seat control system 130. This allows the driver's seat occupant to be moved away from the collision site, while the passenger seat 172 provides protection for the occupant, reducing injury to the driver's seat occupant in a frontal collision. Furthermore, after the driver's seat 172 moves along the first track 171 to the rear of the passenger seat 172, it changes its orientation from facing forward to facing backward, thus providing protection for the occupants in a frontal collision and reducing injury to the driver's seat occupant.

[0173] Step S209: Determine whether the collision location is on the left or right side of vehicle 10.

[0174] When the collision occurs on the left, the driver's seat body 172 is moved to the right side of the vehicle 10 to reduce the injury to the occupants in the collision; when the collision occurs on the right, the passenger seat body 172 is moved to the right side of the vehicle 10 to reduce the injury to the occupants in the collision.

[0175] Step S210: The driver's seat body 172 is moved to the rear side of the passenger seat body 172.

[0176] When the collision location is on the left, the driver's seat body 172 is moved to the rear of the passenger seat body 172, thereby moving the occupant away from the collision location and allowing the occupant's legs on the seat body 172 to face backward, thus reducing the injury to the occupant in the collision.

[0177] Step S211: The passenger seat body 172 is moved to the rear side of the driver's seat body 172.

[0178] When the collision location is on the left, the driver's seat body 172 is moved to the rear of the passenger seat body 172, thereby moving the occupant away from the collision location and allowing the occupant's legs on the seat body 172 to face backward, reducing the injury to the occupant in the collision.

[0179] Step S212: Take over vehicle 10.

[0180] When the probability of a collision between vehicle 10 and other vehicle 20 is predicted to be greater than the second threshold (the second threshold can be set to be less than the first threshold), MDC110 can also take over vehicle 10, lock the steering wheel, and control vehicle 10 to brake through ACC system 120 to reduce the injury to occupants caused by the collision.

[0181] The MDC110 can also activate hazard lights to remind following vehicles to maintain a safe distance; honk the horn and flash the high beams to prompt the vehicle in front to accelerate or pay attention to following vehicles.

[0182] Step S213: Obtain collision intensity information.

[0183] When vehicle 10 collides with vehicle 20, collision sensor 165 can send collision intensity information to MDC110, and MDC110 can determine whether to deploy the airbags based on the collision intensity information.

[0184] Step S214: Determine whether the collision intensity is greater than the second intensity threshold.

[0185] When the collision intensity exceeds the second intensity threshold, the collision intensity is relatively high, and the collision accident will cause injury to the occupants, requiring the airbags to be deployed.

[0186] When the collision intensity is less than or equal to the second intensity threshold, the collision intensity is small, the collision accident will not cause injury to the occupants, and there is no need to deploy the airbags.

[0187] Step S215: Deploy the airbag.

[0188] When the collision intensity exceeds the third threshold, the MDC110 can control the airbag to deploy through the airbag control system 150 to protect the occupants and reduce the injury to the occupants in a collision.

[0189] Step S216: Determine whether it is located at the bottom of another vehicle 20.

[0190] In a positional relationship, where vehicle 10 is located below other vehicle 20, for example, when other vehicle 20 is a large truck or concrete mixer truck, due to the higher front chassis, vehicle 10 will crash into the bottom of other vehicle 20 after colliding with its rear. Therefore, the rear of other vehicle 20 may impact the passenger compartment at a higher position, potentially causing injury to the occupants.

[0191] Step S217: Lower the height of the seat body 172.

[0192] When it is predicted that after a collision, vehicle 10 will be located under other vehicle 20, MDC110 can control the seat body 172 to lower its height through seat control system 130, so as to reduce the injury to the occupants after the rear of other vehicle 20 crashes into the cabin.

[0193] In some embodiments, when the predicted collision probability is less than or equal to a first threshold due to environmental or equipment malfunctions, the MDC110 does not control the seat body 172 to move. However, at the same time, the collision sensor 165 detects a collision with the vehicle 10. When the collision intensity is greater than the first intensity threshold, the MDC110 controls the seat body 172 to move to a position away from the collision location to reduce the injury to the occupants from the collision.

[0194] Figure 15 This is a structural schematic diagram of a computing device 1500 provided in an embodiment of this application. The computing device 1500 includes: a processor 1510, a memory 1520, and a communication interface 1530.

[0195] It should be understood that Figure 15 The communication interface 1530 in the computing device 1500 shown can be used to communicate with other devices.

[0196] The processor 1510 can be connected to the memory 1520. The memory 1520 can be used to store the program code and data.
