[0002] Vehicle seats can activate a zero-gravity function. This function, based on ergonomic principles, adjusts the seat posture at multiple angles to match the human body's curves, ensuring a comfortable and contoured ride. However, in the event of a collision or other hazardous incident, users of zero-gravity seats are more likely to suffer severe injuries. Therefore, minimizing injuries and improving the safety of users of zero-gravity seats during collisions is a crucial technical challenge that requires further investigation.

[0007] In the technical solution of this application embodiment, when a user rides in a vehicle and uses a zero-gravity functional seat, the collision-safe posture of the seat is determined. This collision-safe posture is the seat posture that reduces the injury suffered by the user in the event of a vehicle collision. Subsequently, if a pre-collision signal is received from the vehicle, indicating that a collision event may be imminent, the seat is adjusted to a collision-safe posture. In this way, if a collision occurs, the seat will be in a collision-safe posture, reducing the injury suffered by the user and thus improving the safety of the user when using the zero-gravity functional seat.

[0032] The safety posture determination module is used to determine the collision safety posture of the seat when the vehicle seat is occupied by a user and the zero-gravity function of the seat is activated; wherein, the collision safety posture is the seat posture that reduces the injury to the user when the vehicle is involved in a collision.

[0033] The seat posture adjustment module is used to adjust the seat to a collision-safe posture when a pre-collision signal is received from the vehicle.

[0042] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details.

Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0043] To improve user comfort and alleviate fatigue from long journeys, many vehicles are equipped with zero-gravity seats. Users can activate the zero-gravity function to allow the seat to fully conform to their body, effectively improving comfort. However, in the event of a collision or other dangerous incident, users of zero-gravity seats may suffer more severe injuries. To address these issues, this application provides a vehicle seat control method, device, seat controller, and vehicle that can reduce user injury and improve safety when using zero-gravity seats in the event of a collision or other dangerous incident. For more specific technical details regarding the implementation of this application, please refer to the various method embodiments described below.

[0044] It should be understood that the implementing entity of the various method embodiments of this application is any type of vehicle controller used to control the seats of a vehicle, which may be referred to as a seat controller.

[0045] Please see Figure 1 This application illustrates a vehicle seat control method according to an embodiment of the present application, comprising:

[0046] 101. When a user is sitting in the vehicle's seat and the seat's zero-gravity function is activated, determine the seat's collision safety posture.

[0047] When the vehicle's seat controller detects that a user is sitting in any seat and that seat's zero-gravity function is activated, it calculates the seat's collision-safe posture relative to the user. The collision-safe posture is the seat posture that minimizes injury to the user in the event of a collision. The zero-gravity function refers to multi-angle posture adjustment of the seat, matching the seat surface to the human body's curves. This allows the seat to fully conform to the body, distributing pressure not only through the buttocks but also evenly through the backrest and legs, effectively improving user comfort.

[0048] When a vehicle collides, if the seat is in a zero-gravity position, the user will suffer severe injury. However, if the seat is in a collision-safe position, the user's injury will be significantly reduced. Calculating the collision-safe position involves using devices such as cameras, pressure sensors, and point cloud detection to detect the user's body shape and determine the safest seat position for that body shape in a collision. The safest seat position for each body shape can be obtained and stored in advance through vehicle crash tests. For example, during vehicle testing, dummies of various body shapes can be placed on the seat. Through multiple vehicle crash tests, the damage to these dummies under different seat positions during a collision can be detected, thus identifying the seat position with the least injury for each body shape. The calculated collision-safe positions are stored in advance so that in subsequent collisions, these positions can be directly read to adjust the seat position without recalculation, effectively improving the response speed of seat position adjustment.

[0049] In one implementation of this application, determining the collision safety posture of the seat includes:

[0050] (1) Acquire pressure data detected by the pressure sensor installed on the seat;

[0051] (2) Determine the collision safety posture of the seat based on the pressure data.

[0052] Each seat in a vehicle can be equipped with a number of pressure sensors, which can be distributed in various locations on the seat, such as the seat cushion and backrest. When a user sits in the seat, the various pressure sensors can detect the corresponding pressure data. Based on this pressure data, the user's body shape can be inferred, thereby determining the safest seat posture for that body shape in a vehicle collision scenario, which is then used as the seat's collision-safe posture.

[0053] In one implementation of this application, the pressure sensor includes a seat cushion pressure sensor and a backrest pressure sensor. The pressure data includes first pressure information detected by the seat cushion pressure sensor and second pressure information detected by the backrest pressure sensor. Determining the collision safety posture of the seat based on the pressure data includes:

[0054] (1) Determine the user's weight information based on the first pressure information;

[0055] (2) Determine the user's height information based on the second pressure information;

[0056] (3) Determine the collision safety posture of the seat based on weight and height information.

[0057] The seat cushion is equipped with a seat cushion pressure sensor. The pressure data detected by the sensor is recorded as the first pressure information. Based on this first pressure information, the user's weight information can be determined. Specifically, the pressure information detected by the seat cushion pressure sensor can be obtained when the user first sits down, before the seat's zero-gravity function is activated. Since the seat cushion bears almost all of the user's weight at this time, the user's weight information can be determined based on this pressure information. Alternatively, the pressure information can be obtained after the user activates the seat's zero-gravity function. Although the seat cushion only bears a portion of the user's weight at this time, since the seat back angle is known, the proportion of weight borne by the seat cushion at that back angle can be calculated based on mechanical principles, thus estimating the user's weight information. The seat back is equipped with a backrest pressure sensor. The pressure data detected by the sensor is recorded as the second pressure information. Based on this second pressure information, the user's height information can be determined. Specifically, there are multiple backrest pressure sensors, distributed at various positions on the seat back. In zero-gravity mode, the user's head and back press against the seat back. Therefore, based on the pressure information detected by the backrest pressure sensor, the positions of various body parts such as the user's head, shoulders, and hips can be determined. Combining these positions, the user's height can be estimated. After obtaining the user's weight and height information, the user's body shape can be deduced, allowing the determination of the safest seat posture in a vehicle collision scenario for that body shape, thus establishing the seat's collision safety posture.

[0058] It is understandable that if a seat is used by a new user, the seat controller will recalculate the collision safety posture of the seat based on the new user's body size and update and replace the stored collision safety posture of the seat.

[0059] 102. When a pre-collision signal is received from the vehicle, adjust the seat to a collision-safe position.

[0060] In the technical solution of this application embodiment, the vehicle is equipped with a pre-collision system, which includes devices such as a vehicle speed detection module, a distance detection module, an external camera, millimeter-wave radar, and infrared detectors. These devices can detect the vehicle's speed and the speeds of other surrounding vehicles, the distance between the vehicle and other surrounding vehicles, and information about the surrounding road environment. Based on this information, the pre-collision system can automatically predict the vehicle's collision risk level and collision time, with an error typically below milliseconds. If the detected probability of a collision exceeds a set threshold, the pre-collision system outputs a pre-collision signal, which can be transmitted to the seat controller and the vehicle's safety system via an in-vehicle bus (e.g., CAN bus).

[0061] When a vehicle's safety system receives a pre-collision signal from the pre-collision system, it can deploy airbags to reduce impact injuries to the occupants. Airbags are typically installed in the side wing positions of the seats and in the door positions.

[0062] Upon receiving a pre-collision signal from the pre-collision system, the vehicle's seat controller disables the seat's zero-gravity function, reads the previously stored collision safety posture, and adjusts the seat to that posture. Typically, there is a time interval between the seat controller receiving the pre-collision signal and the actual collision. Because the collision safety posture is pre-calculated and stored, the seat controller can quickly respond and adjust the seat to the collision safety posture within this time interval, thereby reducing the risk of injury to the user during a collision and effectively improving the safety of users using the zero-gravity seat.

[0063] In one implementation of this application, when a pre-collision signal is received from the vehicle, adjusting the seat to a collision-safe posture includes:

[0064] (1) When a pre-collision signal is received from the vehicle, detect whether the seat is still being used by the user and whether the zero-gravity function of the seat is still activated.

[0065] (2) If the seat is still in use by the user and the zero-gravity function of the seat is still activated, adjust the seat to a collision-safe position.

[0066] In some situations, after using the zero-gravity seat, the user may have already left the seat or manually turned off the zero-gravity function and adjusted the seat to a normal position. To accurately handle these situations and improve the precision of seat posture adjustment, when the seat controller receives a pre-collision signal from the vehicle, it can first check whether the seat is still occupied and whether the zero-gravity function is still activated. Only if the seat is still occupied and the zero-gravity function is still activated will the seat be adjusted to a collision-safe posture. If the seat is unoccupied, or the user has already adjusted the seat to a relatively safe normal posture, it is not necessary to adjust the seat to a collision-safe posture. In practice, a zero-gravity unsafe state can be defined for the seat. The seat will only be adjusted to a collision-safe posture when it is in a zero-gravity unsafe state; otherwise, the seat posture will not be adjusted. Specifically, when a pre-collision signal is received, the pressure sensor detects that someone is using the seat, and the seat is in a zero-gravity state, these three conditions are simultaneously met: the seat is determined to be in a zero-gravity unsafe state; otherwise, the seat is determined not to be in a zero-gravity unsafe state.

[0067] In one implementation of this application, when a pre-collision signal is received from the vehicle, before adjusting the seat to a collision-safe posture, the following steps are further included:

[0068] (1) Obtain the vehicle's predicted collision parameters;

[0069] (2) Determine the correction ratio for the collision safety attitude based on the predicted collision parameters;

[0070] (3) Correct the collision safety posture according to the correction ratio.

[0071] Normally, the posture of a seat in zero gravity differs greatly from its collision-safe posture. Therefore, adjusting the seat to this posture can cause extreme discomfort for the user due to the significant change in seat position. In a severe collision, user comfort must be disregarded to ensure safety. However, if the collision is minor, the seat adjustment can be reduced to balance safety and comfort, provided the user is not injured. In practice, the pre-collision system calculates and outputs predicted collision parameters, such as predicted collision direction, location, and speed. Upon receiving these parameters, the seat controller assesses the threat posed to user safety and determines a correction ratio for the collision-safe posture. The seat is then adjusted to this corrected posture. For example, if the threat is high, a 100% correction ratio can be set, resulting in a 100% collision-safe posture – the seat is adjusted to the fully collision-safe position. If the assessment indicates that the collision poses a minimal threat to the user's safety, a 50% correction ratio can be set. This will adjust the seat to a 50% collision safety posture. For example, if a 100% collision safety posture corresponds to a backrest angle adjustment 'a', then a 50% collision safety posture corresponds to a backrest angle adjustment 'a / 2', and so on. This setting ensures both user safety and comfort.

[0072] In one implementation of this application, the predicted collision parameters include the predicted collision direction and the predicted collision speed of the vehicle; determining the correction ratio for the collision safety posture based on the predicted collision parameters includes:

[0073] (1) Determine the severity level of the vehicle collision based on the predicted collision direction and the predicted collision speed;

[0074] (2) Determine the correction ratio based on the severity level; where the severity level is positively correlated with the correction ratio.

[0075] Based on the predicted collision direction and predicted collision speed, the severity level of a vehicle collision can be determined. For example, if the predicted collision direction is frontal and the predicted collision speed is high, the severity level of the collision is determined to be high; if the predicted collision direction is lateral and the predicted collision speed is low, the severity level of the collision is determined to be low. Severity levels can include multiple different levels such as high, relatively high, medium, relatively low, and low. This application does not limit the method or number of severity levels. As an example, if the predicted collision direction is frontal and the predicted collision speed exceeds 30 km / h, the severity level of the collision can be determined to be high; if the predicted collision direction is frontal and the predicted collision speed exceeds 15 km / h but is less than 30 km / h, the severity level of the collision can be determined to be relatively high; if the predicted collision direction is frontal and the predicted collision speed is less than 15 km / h, the severity level of the collision can be determined to be medium; if the predicted collision direction is lateral and the predicted collision speed is less than 5 km / h, the severity level of the collision can be determined to be low, and so on. Different severity levels correspond to different correction ratios, and these are positively correlated; that is, the higher the severity level, the higher the correction ratio. For example, high, higher-middle, medium, lower-middle, and low severity levels correspond to correction ratios of 100%, 90%, 75%, 60%, and 50%, respectively. This setting means that when the severity of a vehicle collision is high, a higher correction ratio, such as 100%, is set, causing the seat to adjust to a 100% collision safety posture, prioritizing the user's safety. When the severity of a vehicle collision is low, a lower correction ratio, such as 50%, is set, causing the seat to adjust to a 50% collision safety posture, ensuring user safety while minimizing seat adjustment to maintain user comfort.

[0076] In one implementation of this application, the collision safety posture includes the target backrest angle, the target footrest angle, the target slide rail position, the target seat cushion angle, and the target headrest height; adjusting the seat to the collision safety posture includes:

[0077] (1) Adjust the seat back to the target backrest angle;

[0078] (2) Adjust the footrest of the seat to the target footrest angle;

[0079] (3) Adjust the seat slide rail to the target slide rail position;

[0080] (4) Adjust the seat cushion to the target seat cushion angle;

[0081] (5) Adjust the headrest of the seat to the target headrest height.

[0082] A vehicle's seating system typically comprises several components, including a backrest, footrest, slide rails, seat cushion, and headrest, each with its own adjustment module. The backrest adjustment module adjusts the seat back and provides feedback on the backrest angle to the seat controller; the footrest adjustment module adjusts the footrest and provides feedback on the footrest angle; the slide rail adjustment module adjusts the slide rails and provides feedback on the slide rail position; the seat cushion adjustment module adjusts the seat cushion and provides feedback on the seat cushion angle; and the headrest adjustment module adjusts the headrest and provides feedback on the headrest height. Since the seat's posture includes the postures of all its components, the collision safety posture can include the target backrest angle, target footrest angle, target slide rail position, target seat cushion angle, and target headrest height. During the process of adjusting the seat to a collision-safe posture: the seat controller sends adjustment commands to the backrest adjustment module, instructing it to adjust the seat back to the target backrest angle; the seat controller sends adjustment commands to the footrest adjustment module, instructing it to adjust the footrest to the target footrest angle; the seat controller sends adjustment commands to the slide rail adjustment module, instructing it to adjust the slide rail to the target slide rail position; the seat controller sends adjustment commands to the seat cushion adjustment module, instructing it to adjust the seat cushion to the target seat cushion angle; and the seat controller sends adjustment commands to the headrest adjustment module, instructing it to adjust the headrest to the target headrest height. By adjusting the posture of each component of the seat in this way, the user can receive a balanced force throughout their body at the moment of a vehicle collision, thereby minimizing the injury suffered by the user.

[0083] As an example, such as Figure 2 The diagram shown is a schematic diagram of a vehicle seat control system provided in an embodiment of this application. Figure 2The vehicle seat control system shown includes a seat adjustment system, a zero-gravity switch, a seat controller, a safety system, and a pre-collision system, which communicate with each other via an in-vehicle bus (such as a CAN bus). The seat adjustment system includes a backrest adjustment module, a footrest adjustment module, a slide rail adjustment module, a seat cushion adjustment module, a headrest adjustment module, a seat cushion pressure sensor, and a backrest pressure sensor. The pre-collision system includes a vehicle speed detection module, a distance detection module, a camera, millimeter-wave radar, and an infrared detector. The safety system mainly includes an airbag module. The pre-collision system detects the speed and distance of the vehicle and surrounding vehicles to determine if there is a risk of collision. If a risk is identified, a pre-collision signal is sent to the seat controller and the safety system. The seat controller can determine whether the seat is in a zero-gravity state based on the feedback from the zero-gravity switch and the current posture of each seat component adjustment module in the seat adjustment system. Upon receiving the pre-collision signal, if the seat controller detects that the user is still sitting in the seat and the seat is in a zero-gravity state, it will adjust the seat to a pre-calculated and stored collision safety posture, thereby minimizing the user's injury during a vehicle collision. Upon receiving a pre-collision signal, the safety system can deploy airbags to further reduce impact injuries to the user. Seat cushion and backrest pressure sensors transmit pressure data to the seat controller, allowing the system to determine if a user is seated and to infer the user's body shape. The backrest adjustment module, footrest adjustment module, slide rail adjustment module, seat cushion adjustment module, and headrest adjustment module are used to transmit the current posture of their respective seat components to the seat controller and to adjust the posture of these components according to adjustment commands sent by the seat controller.

[0084] In the technical solution of this application embodiment, when a user rides in a vehicle and uses a zero-gravity functional seat, the collision-safe posture of the seat is determined. This collision-safe posture is the seat posture that reduces the injury to the user in the event of a vehicle collision. Subsequently, if a pre-collision signal is received from the vehicle, indicating that a collision event may be imminent, the seat is adjusted to a collision-safe posture. Thus, if a collision occurs, the seat will be in a collision-safe posture, minimizing the injury to the user and improving the safety of the user when using the zero-gravity functional seat.

[0085] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution.
