[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The seat adjustment system of the present invention is described below with reference to the accompanying drawings.

[0023] Figure 1 is a schematic diagram of the structure of a seat adjustment system according to an embodiment of the present invention.

[0024] As shown in Figure 1, the seat adjustment system includes: a vehicle seat 101, an information acquisition device 102, a cloud server 103, and a controller 104. The information acquisition device 102 is used to acquire image information and body state information of the target object on the vehicle seat 101; the cloud server 103 is connected to the information acquisition module and is used to obtain a first control signal based on the image information and body state information; the controller 104 is connected to both the cloud server 103 and the vehicle seat 101 and is used to adjust the vehicle seat 101 according to the first control signal.

[0025] Specifically, the cloud server 103 is communicatively connected to the information acquisition device 102 and the controller 104.

[0026] The target object can be either a driver or a passenger, and the information collection device 102 may include a high-definition camera and sensors integrated into the steering wheel. The high-definition camera can collect image information of the target object, and the sensors can collect information about the target object's physical condition.

[0027] The seat adjustment system of this invention generates control signals based on the image information and body state information of the target object, and then controls the vehicle seat 101. It can actively adjust the human posture to reduce or avoid the injury to the driver and passengers in traffic accidents, and at the same time improve the riding experience of the driver and passengers.

[0028] In some embodiments of the present invention, as shown in FIG2, the vehicle seat 101 includes: an active headrest 1011, an active backrest support structure 1012, and an active seat anti-submersion structure 1013; wherein, the controller 104 is connected to the active headrest 1011, the active backrest support structure 1012, and the active seat anti-submersion structure 1013 respectively, and is used to adjust the posture of at least one of the active headrest 1011, the active backrest support structure 1012, and the active seat anti-submersion structure 1013 according to a first control signal.

[0029] Specifically, the active headrest 1011 can move back and forth to adjust the distance between the target's head and the active headrest 1011; it can also move up and down so that when the target's head contacts the active headrest 1011, the target's head is positioned in the center of the active headrest 1011. The active backrest support structure 1012 can tilt back and forth to optimize the distance between the target's back and the active backrest support structure 1012. The active seat anti-submersion structure 1013 can actively submerge or protrude to a predetermined position upon receiving a submersion signal.

[0030] In this embodiment, the vehicle seat 101 includes an active headrest 1011, an active backrest support structure 1012, and an active seat anti-submersion structure 1013, which can adjust the posture of the target object in multiple dimensions. During vehicle operation, it enables the target object to maintain the optimal driving posture to improve the driving experience. At the same time, in the event of an emergency, it enables the target object to be in the optimal response posture to reduce or avoid injury to the target object.

[0031] In some embodiments of the present invention, as shown in FIG3, the seat adjustment system further includes a collision sensor 105. The collision sensor 105 is connected to the controller 104 and is used to generate a collision signal and send it to the controller 104 when a vehicle collision occurs; wherein, the controller 104 is also used to send the collision signal to the cloud server 103 and adjust the vehicle seat 101 according to a second control signal, and the cloud server 103 is also used to obtain the second control signal based on the collision signal, image information and body state information.

[0032] Specifically, there may be multiple collision sensors 105, located at the front and rear of the vehicle respectively. When a collision occurs, they detect the impact intensity of the vehicle and generate a corresponding collision signal to send to the controller 104.

[0033] As an example, the collision sensor 105 can also determine in real time whether a collision is likely to occur. When a collision is detected, a collision signal is generated and sent to the controller 104 to adjust the vehicle seat 101 in advance, reducing the physical harm to the target object in the collision.

[0034] As another example, the collision sensor 105 can also be located on both sides of the vehicle to detect the impact intensity on the side of the vehicle when a collision occurs, and generate a corresponding collision signal to send to the controller 104.

[0035] In this embodiment, by adding a collision sensor 105 to the seat adjustment system, a corresponding collision signal can be generated when a vehicle collision occurs, and a second control signal can be generated by the cloud server 103. The vehicle seat 101 is adjusted according to the second control signal to reduce the physical injury of the target object in a traffic accident.

[0036] In some embodiments of the present invention, the collision signal includes a rear collision signal and a front collision signal. The cloud server 103 is used to: generate a second control signal including first operating parameter information when the collision signal is a rear collision signal; and generate a second control signal including second operating parameter information when the collision signal is a front collision signal. The first operating parameter information includes the active seat back support structure 1012 moving backward a first backrest travel distance and the active headrest 1011 adjusting forward a first headrest travel distance. The second operating parameter information includes the active backrest support structure 1012 moving forward a second backrest travel distance, the active headrest 1011 adjusting forward a second headrest travel distance, and the active seat anti-submersion structure 1013 submerging to the first anti-submersion structure travel distance. The first backrest travel distance, the first headrest travel distance, the second backrest travel distance, the second headrest travel distance, and the first anti-submersion structure travel distance are determined based on image information and body state information. As an example, the collision signal includes a left collision signal and a right collision signal. The cloud server 103 is used to: generate a second control signal including sixth operating parameter information when the collision signal is a left collision signal; and generate a second control signal including seventh operating parameter information when the collision signal is a front collision signal.

[0037] In this embodiment, when the vehicle driven by the driver collides with the vehicle in front, a forward collision signal is generated, and the active backrest support structure 1012 is adjusted to move forward by a second backrest travel distance, which can reduce neck injury to the target. Controlling the active headrest 1011 to adjust the second headrest travel distance forward can reduce potential secondary head injuries to the target. Adjusting the active seat anti-submersion structure 1013 to the distance of the first anti-submersion structure can reduce the damage caused by the collision and lower the probability of secondary injuries. Similarly, when a vehicle rear-ends the vehicle driven by the target, a rear collision signal is generated, and the active backrest support structure 1012 is adjusted to move backward by a first backrest travel distance, which can reduce neck injury to the target. Controlling the active headrest 1011 to adjust the first headrest travel distance forward can also reduce neck injury to the target.

[0038] In some embodiments of the present invention, as shown in FIG4, the cloud server 103 is used for:

[0039] S1: Based on image information and body condition information, obtain the actual vital signs information of the target object.

[0040] S2, matches the actual vital signs information with the standard vital signs information, and generates the first control signal based on the matching result.

[0041] The standard vital signs information of the target object can be obtained from the user historical status database in the cloud server 103. The user historical status database may include vital signs information corresponding to different image information and different physical status information of the user.

[0042] It should be noted that when the cloud server 103 cannot obtain the corresponding standard vital sign information in the user's historical status database, it can search for standard vital sign information that matches the actual vital sign information in the overall user historical status database, using this as the matching result, and generate the first control signal. After adjusting the vehicle seat 101, the system can ask the user whether they are satisfied with the adjustment. If satisfied, the adjustment data will be recorded in the user's historical status database.

[0043] In this embodiment, the cloud server 103 generates a first control signal by matching actual vital signs information with standard vital signs information, which can reduce the system's reaction time and make timely adjustments to the vehicle seat 101.

[0044] In some embodiments of the present invention, the cloud server 103 is used to: generate a first control signal including third operating parameter information when it is determined that the target object is in a state of fatigued driving based on the matching result; generate a first control signal including fourth operating parameter information when it is determined that the target object is in a state of physical discomfort based on the matching result; and generate a first control signal including fifth operating parameter information when it is determined that the target object is in a normal physical state based on the matching result.

[0045] The third operating parameter information includes the forward / backward movement distance of the active backrest support structure 1012 and the forward / backward adjustment distance of the active headrest 1011. The fourth operating parameter information includes the backward / forward movement distance of the active backrest support structure 1012 and the backward / backward adjustment distance of the active headrest 1011. The fifth operating parameter information includes the downward / upward movement distance of the active seat anti-submersion structure 1013 to the second anti-submersion structure. The third backrest movement distance, the third headrest movement distance, the movement distance of the fourth backrest, the movement distance of the fourth headrest, and the movement distance of the second anti-submersion structure are determined based on image information and body status information.

[0046] In this embodiment, by judging the different physical and driving states of the target object, a first control signal including different operating parameter information is generated accordingly, which can provide prompts to the target object and improve the driving experience.

[0047] In some embodiments of the present invention, the seat adjustment system further includes: a warning device connected to the controller 104; wherein, the cloud server 103 is further configured to generate a warning signal when it is determined that the target object is in a state of fatigued driving or physical discomfort based on the matching result, and the controller 104 is further configured to control the warning device to perform a warning action based on the warning signal.

[0048] In this embodiment, by adding a warning device to the seat adjustment system, timely reminders can be given when the target is in a state of fatigued driving or physical discomfort, thus preventing traffic accidents.

[0049] In some embodiments of the present invention, the warning device includes: a first warning module connected to the controller 104, which emits an audible and visual alarm signal, and / or a second warning module connected to the controller 104, which emits a vibration signal.

[0050] As an example, a vibrator can be installed in the vehicle seat 101. This vibrator is connected to the second warning module. When the target is detected to be in a state of fatigue driving, the vibrator is controlled to vibrate via a vibration signal to alert the target. The first warning module is connected to the vehicle ambient light. When the target is detected to be in a state of physical discomfort, the first warning module can provide a voice prompt and simultaneously control the vehicle ambient light to flash red intermittently via an audible and visual alarm signal to warn the target to stop driving or riding in the vehicle.

[0051] In this embodiment, when the target is in a state of fatigued driving or physical discomfort, the target can be promptly alerted through audible and visual alarm signals and vibration signals.

[0052] In some embodiments of the present invention, standard vital sign information is determined based on the historical vital sign information of the target object.

[0053] The cloud server 103 also includes the seat posture commonly used by the target object. When the actual vital signs information cannot match the standard vital signs information, the vehicle seat 101 can be adjusted through the seat posture commonly used by the target object.

[0054] In some embodiments of the present invention, the cloud server 103 is also used to count the cumulative time during which the corresponding state of vital signs remains unchanged, and when the cumulative time reaches a preset time, a third control signal is generated, and the controller 104 is also used to adjust the vehicle seat 101 according to the third control signal.

[0055] In this embodiment, when the cumulative time for which the target object's vital signs remain unchanged reaches a preset time, a third control signal is generated to adjust the vehicle seat 101. This can prevent the target object from becoming inattentive or drowsy, while also alleviating the discomfort caused by a single driving posture for a long time and improving the driving comfort of the target object.
