[0095] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0096] This invention provides a car seat control method that can be applied to an in-vehicle controller. The method determines the current occupant state based on real-time collected data of the first seat state and the first door state. Then, it determines the target position of the car seat based on the identification data corresponding to the current occupant state, ensuring the target position of the car seat matches the current occupant state. The method then controls the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work according to the target position, matching the armrest height and / or seat position with the current occupant state, thus meeting the occupant's actual needs and ensuring their comfort and convenience.

[0097] As an example, the vehicle controller can be an existing controller on the vehicle or a dedicated controller separately installed on the vehicle seat. The dedicated controller can work with the existing controller on the vehicle to determine the target position of the vehicle seat based on the first seat state, the first door state, and the data to be identified forwarded by the existing controller, thereby controlling the operation of the armrest adjustment mechanism 2 and / or the position adjustment mechanism of the vehicle seat.

[0098] This invention provides a method for controlling a car seat, such as... Figure 1 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0099] S1: Determine the current status of the occupants based on the status of the first seat and the status of the first door;

[0100] S2: Obtain the identification data corresponding to the current state of the occupant;

[0101] S3: Based on the data to be identified, determine the target position corresponding to the car seat, and control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work according to the target position.

[0102] The first seat state refers to the seat state determined at the current moment. As an example, the first seat state can be either a occupied state or an unoccupied state. An occupied state means that at the current moment, a passenger is sitting in the car seat, specifically sitting in the seat, so that the seat sensor installed on the seat can detect a passenger signal; conversely, an unoccupied state means that at the current moment, no passenger is sitting in the car seat, so that the seat sensor cannot detect a passenger signal.

[0103] The first door state is the door state determined at the current moment. As an example, the first door state can be either open or closed.

[0104] The current state of the occupant is determined based on the state of the first seat and the state of the first door. As an example, the current state can be any one of the following: not boarding, waiting to board, or already seated. The "not boarding" state means the occupant has not boarded and is not ready to board at the current moment. The "waiting to board" state means the occupant has not boarded but is ready to board at the current moment. The "already seated" state means the occupant has boarded and is seated at the current moment.

[0105] As an example, in step S1, the vehicle controller can acquire the current status of the first seat and the first door. Specifically, this can be achieved through a bus or by acquiring the first seat and first door statuses separately through connected sensors. Then, based on the combination of the first seat and first door statuses, a comprehensive assessment is made as to whether the occupant has boarded the vehicle. If not, the assessment determines whether the occupant is ready to board, thus confirming the occupant's current status. In this example, the real-time acquisition of the first seat and first door statuses ensures the objectivity and real-time nature of the determination of the occupant's current status.

[0106] The data to be identified refers to the data collected after determining the current state of the occupant, which is used to control the operation of the car seat.

[0107] As an example, in step S2, after determining the occupant's current state, the vehicle controller needs to further acquire the identification data corresponding to that current state. This identification data can be understood as the input parameters needed to control the operation of the car seat in the occupant's current state, i.e., the data collected to determine the target position of the car seat. In this example, acquiring the identification data corresponding to the occupant's current state ensures the compatibility between the identification data and the occupant's current state. This helps ensure that the target position of the car seat determined based on the identification data can meet the occupant's actual needs, thereby improving comfort and convenience.

[0108] The target position of a car seat refers to the position where the car seat needs to be adjusted. As an example, the target position of the car seat may include the target position of the armrest and / or the target position of the seat itself. Here, the target position of the armrest is the position where the armrest needs to be moved. The target position of the seat is the position where the seat needs to be moved, specifically the position where the position adjustment mechanism needs to be controlled to move the seat.

[0109] As an example, in step S3, after the vehicle controller collects the identification data corresponding to the current state of the occupant, it needs to analyze the collected identification data in conjunction with the current state of the occupant to determine the target position corresponding to the car seat. The target position is the armrest target position and / or the seat target position. Then, the vehicle controller can control the armrest adjustment mechanism 2 to work based on the armrest target position, and / or control the position adjustment mechanism to work based on the seat target position.

[0110] In this embodiment, the current state of the occupant is first determined based on the first seat state and the first door state to ensure the objectivity and real-time nature of the determination of the current state of the occupant; according to the data to be identified corresponding to the current state of the occupant, the target position of the car seat is determined so that the target position of the car seat is adapted to the current state of the occupant; the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to work according to the target position so that the target position of the car seat matches the current state of the occupant, meets the actual needs of the occupant, and ensures their comfort and convenience.

[0111] This invention provides a method for controlling a car seat, such as... Figure 2 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0112] S11: When the first seat is in an unoccupied state and the first door is in a closed state, determine that the current state of the occupant is an unoccupied state;

[0113] S12: Obtain the first distance data and the first camera data corresponding to the "not on the vehicle" state;

[0114] S13: Based on the first distance data and the first camera data, determine the convenient entry position corresponding to the car seat, and control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work according to the convenient entry position.

[0115] Wherein, step S11 is a specific implementation of step S1, step S22 is a specific implementation of step S2, and step S13 is a specific implementation of step S3.

[0116] As an example, in step S11, the vehicle controller can obtain the current state of the first seat and the state of the first door. When the first seat is in an unoccupied state and the first door is in a closed state, it can be determined that the seat in the vehicle is unoccupied and the door is closed at the current time. This means that the passenger has not yet boarded the vehicle and is not ready to board (such as opening the door). Therefore, it can be determined that the passenger's current state is an unoccupied state.

[0117] The first distance data refers to the distance data collected after determining the current state of the occupants, specifically the distance between the vehicle and the occupants. The first camera data refers to the camera data collected after determining the current state of the occupants, specifically the camera data collected in real time by the camera.

[0118] As an example, in step S12, when the vehicle controller determines that the current state of the passenger is not in the vehicle, it needs to collect first distance data and first camera data to assess whether the passenger is ready to board the vehicle, so as to assess whether the passenger is ready to board the vehicle based on the first distance data and the first camera data, and make adaptive adjustments.

[0119] In this context, a convenient entry position refers to a position where the car seat needs to be adjusted to facilitate passenger entry. As an example, a convenient entry position includes an armrest convenient position and / or a seat convenient position. Here, an armrest convenient position refers to a position where the armrest needs to be moved to facilitate entry and exit, and a seat convenient position refers to a position where the seat adjustment mechanism needs to be adjusted to move the entire seat to facilitate entry and exit.

[0120] As an example, in step S13, after the vehicle controller collects the first distance data and the first camera data corresponding to the non-boarding state, it needs to assess whether the passenger is ready to board the vehicle based on the first distance data and the first camera data. When it is determined that the passenger is ready to board the vehicle, it needs to further determine the convenient boarding position based on the first distance data and the first camera data, that is, determine the convenient armrest position and / or the convenient seat position. Then, the vehicle controller can control the armrest adjustment mechanism 2 to work based on the convenient armrest position to adjust the armrest height to the convenient armrest position, and / or control the position adjustment mechanism to work based on the convenient seat position to control the seat to move as a whole to the convenient seat position, thereby facilitating the passenger to board the vehicle and ensuring the comfort and convenience of the passenger's boarding process.

[0121] In this embodiment, when the first seat is in an unoccupied state and the first door is in a closed state, the current state of the passenger is determined to be an unboarded state. Based on the first distance data and the first camera data corresponding to the unboarded state, a convenient boarding position is determined. The armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to work according to the convenient boarding position, so that the armrest height and / or seat position are convenient for the passenger to board the vehicle, meet the passenger's boarding needs, and ensure the comfort and convenience of the passenger boarding process.

[0122] In one embodiment, step S13, determining the convenient entry location corresponding to the car seat based on the first distance data and the first camera data, includes:

[0123] S131: Based on the first distance data and the first camera data, determine whether the conditions for boarding are met;

[0124] S132: If the conditions for getting into the vehicle are met, control the car seat to enter the preparation state and obtain the door opening angle and the current position of the seat;

[0125] S133: Determine the convenient entry position of the car seat based on the door opening angle and the current seat position.

[0126] Among them, the boarding preparation conditions are pre-set conditions used to assess whether passengers are ready to board the vehicle.

[0127] As an example, in step S131, after the vehicle controller collects the first distance data and the first camera data corresponding to the non-boarding state, it needs to determine whether the boarding preparation conditions are met based on the first distance data and the first camera data, so as to assess whether the passenger is ready to board the vehicle and make adaptive adjustments.

[0128] The door opening angle refers to the angle at which the occupant opens the car door; specifically, it's the door hinge sensor's data on the door opening angle when the occupant opens the door. The current seat position is the real-time position of the car seat as collected by the vehicle controller in the current state. Specifically, it can be the seat's fore-and-aft position identified by the vehicle controller through the Hall effect signals from the seat's fore-and-aft slide rail motors.

[0129] As an example, in step S132, if the first distance data and the first camera data corresponding to the vehicle controller in the non-vehicle state meet the conditions for occupant to board the vehicle, the vehicle controller determines the convenient boarding position based on the first distance data and the first camera data, controls the car seat to enter the preparation state, and collects the door opening angle and the current position of the seat so that the convenient boarding position can be determined later based on the door opening angle and the current position of the seat.

[0130] As an example, in step S133, after the vehicle controller collects the door opening angle and the current seat position, it needs to determine the convenient boarding position corresponding to the car seat for the passenger to sit on, based on the door opening angle and the current seat position. The convenient boarding position here includes the convenient armrest position and / or the convenient seat position. Then, the vehicle controller can control the armrest adjustment mechanism 2 to work based on the convenient armrest position to adjust the armrest height to the convenient armrest position, and / or control the position adjustment mechanism to work based on the convenient seat position to control the entire seat to move to the convenient seat position, thereby facilitating the passenger to board the vehicle and ensuring the comfort and convenience of the boarding process.

[0131] In this embodiment, based on the first distance data and the first camera data, it is determined whether the conditions for boarding are met. If the conditions for boarding are met, the car seat is controlled to enter the preparation state. By acquiring the door opening angle and the current position of the seat, the corresponding convenient boarding position of the car seat is determined, so that the armrest height and / or seat position corresponding to the convenient boarding position facilitates the passenger's boarding, meets the passenger's boarding needs, and ensures the comfort and convenience of the passenger's boarding process.

[0132] In one embodiment, step S131, determining whether the boarding preparation conditions are met based on the first distance data and the first camera data, includes:

[0133] S1311: If the first distance data is less than the first distance threshold, then the current direction of movement of the occupant is determined based on the first camera data;

[0134] S1312: If the current direction of movement is from front to back along the front-to-back direction of the vehicle body, the current position of the occupant is determined according to the first camera data. When the current position of the occupant reaches the front door handle, it is determined that the conditions for boarding are met.

[0135] S1313: If the current direction of movement is from back to front along the front-rear direction of the vehicle body or from far to near along the direction directly facing the door, then the current face angle of the occupant facing the rear door is determined according to the first camera data. If the current face angle is less than the first preset angle, it is determined that the conditions for boarding are met.

[0136] The first distance threshold refers to a pre-set distance threshold, specifically used to determine whether a passenger is preparing to board the vehicle. The passenger's current direction of movement refers to the direction of movement identified based on the first camera data.

[0137] As an example, in step S1311, the vehicle controller collects the first distance data and the first camera data corresponding to the non-boarding state, compares the first distance data with the first distance threshold, and if the first distance data is less than the first distance threshold, it is determined that the passenger has entered the distance range for preparing to board the vehicle; then, based on the first camera data collected by the vehicle controller, the current movement direction of the passenger is determined, and the current movement direction of the passenger is further evaluated to determine whether the passenger currently meets the conditions for preparing to board the vehicle, so as to make adaptive adjustments.

[0138] As an example, in step S1312, if the vehicle controller detects that the occupant's current movement direction is from front to back along the front-to-back direction of the vehicle, it is necessary to further determine the occupant's current position based on the first camera data. If the first camera data determines that the occupant's current position is at the front door handle position, it is determined that the occupant has walked from front to back along the front-to-back direction of the vehicle to the front door handle position, which is highly likely to be preparing to get into the vehicle. At this time, it is determined that the condition of preparing to get into the vehicle is met.

[0139] The first preset angle refers to the pre-set angle data, specifically the preset angle of the face facing the back door.

[0140] As an example, in step S1313, if the vehicle controller detects that the occupant's current movement direction is from back to front along the vehicle's front-rear direction, or from far to near the door, it is necessary to further determine the current facial angle of the occupant facing the rear door based on the first camera data. By comparing the current facial angle with a first preset angle, if the current facial angle is less than the first preset angle, it is determined that the occupant is moving from back to front along the vehicle's front-rear direction or from far to near along the door. When the angle of the occupant's face facing the rear door is small, it is highly likely that the occupant is preparing to get on the vehicle. At this time, it can be determined that the occupant meets the conditions for getting on the vehicle. By determining the current facial angle of the occupant, it is possible to further determine whether the occupant is preparing to get on the vehicle so as to make adaptive adjustments.

[0141] In this embodiment, when the first distance data is less than the first distance threshold, the current movement direction of the occupant is determined based on the first camera data. If the current movement direction is from front to back along the front-rear direction of the vehicle and reaches the front door handle, it is determined that the conditions for boarding are met. If the current movement direction is from back to front along the front-rear direction of the vehicle or from far to near along the direction directly facing the door, and the current angle of the occupant's face facing the rear door is less than the first preset angle, it is determined that the conditions for boarding are met. By judging the conditions for boarding, the car seat can make better adaptive adjustments to ensure the comfort and convenience of the occupant's boarding process.

[0142] In one embodiment, step S133, determining the convenient entry position corresponding to the car seat based on the door opening angle and the current seat position, includes:

[0143] S1331: Get the current door type;

[0144] S1332: If the current door type is a sliding door, determine the corresponding convenient entry position of the car seat based on the current position of the seat;

[0145] S1333: If the current door type is not a sliding door, determine the convenient entry position of the car seat based on the door opening angle and the current seat position.

[0146] Here, "current door type" refers to the type of vehicle door, which can be either a sliding door or a non-sliding door. A sliding door is one that can open to its maximum angle. A non-sliding door is one that cannot open to its maximum angle.

[0147] As an example, in step S1331, after the vehicle controller collects the information that the occupant meets the conditions for boarding, it needs to obtain the current door type so that it can determine the convenient boarding position of the car seat based on the current door type, the door opening angle and the current position of the seat.

[0148] As an example, in step S1332, when the current door type is a sliding door, the vehicle controller can determine that the door can be opened to its maximum angle, meaning that the door opening will not be affected by the surrounding environment, and the door opening angle will not affect the convenient boarding position. Therefore, the vehicle controller can determine the convenient boarding position based on the current seat position, i.e., determine the convenient armrest position and / or the convenient seat position. Then, the vehicle controller can control the armrest adjustment mechanism 2 to work based on the convenient armrest position to adjust the armrest height to the convenient armrest position, and / or control the position adjustment mechanism to work based on the convenient seat position to control the seat to move as a whole to the convenient seat position, thereby facilitating passenger boarding and ensuring the comfort and convenience of the passenger boarding process.

[0149] As an example, in step S1333, when the current door type is not a sliding door, the vehicle controller can determine that the door opening method is not a sliding method, and the door opening angle will be affected by the surrounding environment. At this time, the door opening angle will affect the convenient position for getting on the vehicle. Therefore, the vehicle controller needs to collect the door opening angle and the current position of the seat, and determine the convenient position for getting on the vehicle based on the door opening angle and the current position of the seat, that is, determine the convenient position of the armrest and / or the convenient position of the seat. Then, the vehicle controller controls the armrest adjustment mechanism 2 to work based on the convenient position of the armrest to adjust the armrest height to the convenient position of the armrest, and / or controls the position adjustment mechanism to work based on the convenient position of the seat to control the seat to move as a whole to the convenient position of the seat, thereby facilitating the passenger to get on the vehicle and ensuring the comfort and convenience of the passenger's boarding process.

[0150] In this embodiment, when the current door type is a sliding door, the corresponding convenient entry position for the car seat can be determined based on the current seat position. When the current door type is not a sliding door, the corresponding convenient entry position for the car seat is determined based on the door opening angle and the current seat position. In this example, the convenient entry positions for car seats corresponding to different door types can be determined, thereby controlling the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work, so that the armrest height and / or seat position match different door types, meeting the entry needs of passengers and ensuring the comfort and convenience of the entry process.

[0151] In one embodiment, step 1332, determining the convenient entry location corresponding to the car seat based on the current position of the seat, includes:

[0152] S13321: If the current position of the seat is before the first seat calibration position, then the lowest position of the armrest and / or the second seat calibration position shall be determined as the corresponding convenient position for getting into the car seat.

[0153] S13322: If the current position of the seat is after the first seat's designated position, then the current position of the seat is determined as the convenient entry position corresponding to the car seat.

[0154] The second seat calibration position is the position after the first seat calibration position.

[0155] The first seat calibration position refers to the pre-set fore-and-aft position of the first seat, the specific position of which can be obtained through data simulation or calibrated according to the vehicle model. The second seat calibration position is the pre-set second fore-and-aft position of the second seat, specifically located after the first seat calibration position along the front-to-back direction of the vehicle body.

[0156] As an example, in step S13321, before the vehicle controller identifies the current position of the seat at the first seat calibration position, it determines that the current position of the seat will affect the passenger's entry into the vehicle. At this time, the lowest position of the armrest and / or the second seat calibration position can be determined as the convenient entry position corresponding to the car seat. Based on the determined convenient entry position, the vehicle controller controls the armrest adjustment mechanism 2 to work based on the convenient entry position to adjust the armrest height to the lowest position of the armrest, and / or controls the position adjustment mechanism to work based on the convenient entry position to move the entire car seat to the second seat calibration position, thereby facilitating the passenger's entry into the vehicle and ensuring the comfort and convenience of the entry process.

[0157] As an example, in step S13322, if the vehicle controller recognizes that the current position of the seat is after the first seat calibration position, it means that the current position of the seat will not affect the passenger getting into the vehicle. Therefore, the current position of the seat is determined to be the convenient position for getting into the vehicle corresponding to the car seat. Based on the determined convenient position for getting into the vehicle, the armrest is controlled to keep its current position unchanged, and the overall position of the seat is controlled to keep its current position unchanged. That is, there is no need to work on the armrest and / or position adjustment mechanism, thereby facilitating the passenger to get into the vehicle and ensuring the comfort and convenience of the getting process.

[0158] In this embodiment, if the current position of the seat is before the first seat calibration position, the lowest position of the armrest and / or the second seat calibration position are determined as the corresponding convenient entry position for the car seat; if the current position of the seat is after the first seat calibration position, the current position of the seat is determined as the corresponding convenient entry position for the car seat. The armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to work according to the corresponding convenient entry position, so that the armrest height and / or seat position meet the entry needs of passengers preparing to board a sliding door type vehicle, ensuring the comfort and convenience of the passengers during the entry process.

[0159] In one embodiment, step S1333, determining the convenient entry position corresponding to the car seat based on the door opening angle and the current seat position, includes:

[0160] S13331: Perform obstacle detection within a preset area of ​​the vehicle and obtain the obstacle detection results;

[0161] S13332: If the obstacle detection result is that there is no obstacle, and the current position of the seat is before the first seat calibration position, then the lowest position of the armrest and / or the second seat calibration position shall be determined as the corresponding convenient position for getting into the car seat.

[0162] S13333: If the obstacle detection result indicates the presence of an obstacle and the door opening angle is less than the second preset angle, then the lowest position of the armrest and the last position of the seat will be determined as the convenient entry positions corresponding to the car seats.

[0163] S13334: If the obstacle detection result indicates the presence of an obstacle, the door opening angle is not less than the second preset angle, and the current seat position is before the first seat calibration position, then the lowest position of the armrest and / or the second seat calibration position are determined as the convenient entry position corresponding to the car seat.

[0164] S13335: If the obstacle detection result indicates the presence of an obstacle, the door opening angle is not less than the second preset angle, and the current seat position is after the first seat calibration position, then the current position of the armrest and the current position of the seat are determined as the convenient entry position corresponding to the car seat.

[0165] Among them, the vehicle preset range is a preset range centered on the vehicle, especially the vehicle door.

[0166] As an example, in step S13331, after the vehicle controller detects that the current door type is a non-sliding door type, it needs to perform obstacle detection on the vehicle's preset range to obtain the obstacle detection results of whether there are obstacles within the vehicle's preset range, so as to dynamically adjust its convenient entry position based on the obstacle detection results.

[0167] The lowest position of the armrest refers to the lowest point when the armrest is raised or lowered. The final position of the seat refers to the final position when the seat is moved forward or backward.

[0168] As an example, in step S13332, before the obstacle detection result indicates the absence of an obstacle and before the current seat position is acquired at the first seat calibration position, the vehicle controller can determine that the current positions of the armrest and the seat will affect the occupant's entry into the vehicle, but the impact is minor. Therefore, the lowest position of the armrest and / or the second seat calibration position can be determined as the corresponding convenient entry position for the car seat. Based on the determined convenient entry position, the vehicle controller then controls the armrest adjustment mechanism 2 to operate based on the convenient armrest position to adjust the armrest height to the lowest position, and / or controls the position adjustment mechanism to operate based on the convenient seat position to control the overall movement of the car seat to the second seat calibration position, thereby facilitating the occupant's entry into the vehicle and ensuring the comfort and convenience of the occupant's entry process.

[0169] The second preset angle refers to the pre-set angle data, specifically the preset angle value when the car door is opened.

[0170] As an example, in step S13333, when the obstacle detection result indicates the presence of an obstacle and the door opening angle is less than the second preset angle, the vehicle controller can determine that the current positions of the armrest and seat significantly affect the passenger's entry into the vehicle. Therefore, the lowest position of the armrest and the last position of the seat can be determined as the corresponding convenient entry positions for the car seat. Based on the determined convenient entry positions, the vehicle controller can then control the armrest adjustment mechanism 2 to operate based on the convenient armrest position to adjust the armrest height to the lowest position, and / or control the position adjustment mechanism to operate based on the convenient seat position to control the entire car seat to move to the last position, thereby facilitating the passenger's entry into the vehicle and ensuring the comfort and convenience of the entry process.

[0171] As an example, in step S13334, when the obstacle detection result indicates the presence of an obstacle, the door opening angle is not less than the second preset angle, and the current seat position is before the first seat calibration position, the vehicle controller can determine that the current positions of the armrest and the seat will affect the occupant's entry into the vehicle, but to a relatively minor degree. Therefore, the lowest position of the armrest and / or the second seat calibration position can be determined as the corresponding convenient entry position for the car seat. The vehicle controller then controls the armrest adjustment mechanism 2 to operate based on the convenient armrest position to adjust the armrest height to the lowest position, and / or controls the position adjustment mechanism to operate based on the convenient seat position to control the overall movement of the car seat to the second seat calibration position, thereby facilitating the occupant's entry into the vehicle and ensuring the comfort and convenience of the occupant's entry process. Here, the second seat calibration position refers to the position between the first seat calibration position and the last seat position.

[0172] As an example, in step S13335, if the obstacle detection result indicates the presence of an obstacle, the door opening angle is not less than the second preset angle, and the current seat position is after the first seat calibration position, the vehicle controller can determine that the current position of the armrest and the current position of the seat will not affect the passenger's entry into the vehicle. At this time, the current position of the armrest and the current position of the seat are determined as the convenient entry position corresponding to the car seat. The vehicle controller controls the armrest adjustment mechanism 2 to work based on the convenient armrest position to keep the current position of the armrest unchanged, and / or controls the position adjustment mechanism to work based on the convenient seat position to keep the current position of the seat unchanged, thereby facilitating the passenger's entry into the vehicle and ensuring the comfort and convenience of the passenger's entry process.

[0173] In this embodiment, based on the obstacle detection results, the door opening angle, and the current seat position, a comprehensive assessment is made to determine whether there are any objective circumstances that may affect passengers getting on the vehicle. If so, the corresponding target positions of the armrest and / or the seat are determined according to different circumstances, and the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to work so that the armrest height and / or the seat position meet the passengers' boarding needs, ensuring the comfort and convenience of the passengers' boarding process.

[0174] This invention provides a method for controlling a car seat, such as... Figure 3 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0175] S21: When the first seat is in an unoccupied state and the first door is in an open state, determine that the current state of the passenger is a waiting-to-board state;

[0176] S22: Obtain the status of the second seat corresponding to the waiting-to-board status;

[0177] S23: If the second seat is in a occupied state, determine the corresponding comfortable seating position of the car seat based on the occupant identification data, and control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work based on the comfortable seating position;

[0178] S24: If the second seat is in an unoccupied state, determine the convenient position for retrieving items corresponding to the car seat according to the door control command and the current vehicle speed, and control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work based on the convenient position for retrieving items.

[0179] Wherein, step S21 is a specific implementation of step S1, step S22 is a specific implementation of step S2, and steps S23 and S24 are specific implementations of step S3.

[0180] As an example, in step S21, the vehicle controller can obtain the current state of the first seat and the state of the first door. When the first seat is in an unoccupied state and the first door is in an open state, it can be determined that the seat in the vehicle is unoccupied and the door is open at the current time, indicating that the passenger is ready to get on the vehicle. Therefore, it can be determined that the passenger's current state is the waiting-to-get-on state.

[0181] The second seat state refers to the seat state determined at the current moment. As an example, the second seat state can be either a occupied state or an unoccupied state. An occupied state means that there is a passenger sitting in the car seat at the current moment, specifically sitting in the seat so that the seat sensors installed on the seat can detect the corresponding signal; conversely, an unoccupied state means that there is no passenger sitting in the car seat at the current moment, so that the seat sensors cannot detect the corresponding signal.

[0182] As an example, in step S22, when the vehicle controller determines that the occupant's current state is a waiting-to-board state, it needs to collect the second seat state corresponding to the waiting-to-board state in order to assess whether the occupant is ready to board based on the second seat state, so as to make adaptive adjustments.

[0183] As an example, in step S23, the vehicle controller, upon detecting that the second seat is occupied, determines that the car seat is currently occupied. It then collects occupant identification data using in-vehicle detection equipment, such as in-vehicle camera footage, and identifies this footage as occupant identification data. Next, it performs identity verification on the occupant identification data, for example, using, but not limited to, facial recognition technology, to obtain occupant identity information. Then, it queries the system database based on the identified occupant identity information to obtain the corresponding comfortable seating position. Following this, the vehicle controller controls the armrest adjustment mechanism 2 to operate based on the matched comfortable seating position, adjusting the armrest height to a comfortable position suitable for the occupant, and / or controls the position adjustment mechanism to operate based on the matched comfortable seating position, controlling the entire car seat to move to a comfortable position suitable for the occupant, thereby ensuring the comfort and convenience of the occupant.

[0184] Here, the door control command refers to the door status command determined at the current moment. As an example, the door control command can be either an open door command or a close door command. The current vehicle speed refers to the vehicle speed determined at the current moment. As an example, the current vehicle speed can be either zero or non-zero.

[0185] As an example, in step S24, when the vehicle controller detects that the second seat is unoccupied, it determines that the car seat is currently unoccupied. Based on the door control command received at the current moment and the current vehicle speed, it determines the convenient position for retrieving items from the car seat. Then, the vehicle controller controls the armrest adjustment mechanism 2 to adjust the armrest height to a convenient position for the passenger to retrieve items, and / or controls the position adjustment mechanism to work based on the convenient position for retrieving items, so as to control the entire car seat to move to a convenient position for the passenger to retrieve items, thereby making it convenient for the passenger to retrieve items and ensuring the comfort and convenience of the passenger.

[0186] In this embodiment, when the first seat is in an unoccupied state and the first door is in an open state, the occupant's current state is determined to be a waiting-to-board state. If the second seat corresponding to this waiting-to-board state is an occupied state, then based on the occupant identification data, the corresponding comfortable seating position for the car seat is determined, and the armrest adjustment mechanism 2 and / or the position adjustment mechanism are activated. If the second seat is unoccupied, then based on the door control command and the current vehicle speed, the corresponding convenient access position for retrieving items for the car seat is determined. Based on the comfortable seating position or the convenient access position, the armrest adjustment mechanism 2 and / or the position adjustment mechanism are activated to match the armrest height and / or seat position with the waiting-to-board state, meeting the occupant's boarding needs and ensuring the comfort and convenience of the boarding process.

[0187] In one embodiment, step S24, determining the convenient location for retrieving items corresponding to the car seat based on the door control command and the current vehicle speed, includes:

[0188] S241: If the current vehicle speed is zero, then the current position of the armrest and the current position of the seat are determined as the convenient location for retrieving items corresponding to the car seat;

[0189] S242: If the current vehicle speed is not zero and the door control command is a door closing command, then the last optimal use position on the armrest is determined as the convenient position for retrieving items corresponding to the car seat.

[0190] Among them, the door control command and the current vehicle speed are used to determine the convenient position for retrieving items from the car seat under different circumstances.

[0191] As an example, in step S241, if the current vehicle speed is zero, it can be determined that the occupant is most likely still retrieving an item at the current moment, and the current position of the armrest and the current position of the seat can be determined as convenient positions for retrieving items corresponding to the car seat; then, the vehicle controller controls the armrest adjustment mechanism 2 to work based on the convenient positions for retrieving items, controls the armrest to keep its current position unchanged, and / or controls the position adjustment mechanism to work based on the convenient positions for retrieving items, controls the seat to keep its current position unchanged, so that it is convenient for the occupant to retrieve items, and ensures the comfort and convenience of the occupant in retrieving items.

[0192] As an example, in step S242, if the vehicle controller detects that the current door control command is a door closing command and the current vehicle speed is not zero, it can be determined that the occupant has most likely finished retrieving the item at the current moment, and the vehicle is restarted. At this time, the last optimal use position of the armrest can be set as the convenient retrieval position corresponding to the car seat. Then, the vehicle controller controls the armrest adjustment mechanism 2 to work based on the convenient retrieval position, and controls the armrest to reset to the last optimal use position to facilitate the occupant's next retrieval and ensure the comfort and convenience of the occupant in retrieving the item.

[0193] In this embodiment, if the current vehicle speed is zero, the current position of the armrest and the current position of the seat are determined as the convenient retrieval position corresponding to the car seat; if the door control command is a door closing command and the current vehicle speed is not zero, the last optimal use position of the armrest is determined as the convenient retrieval position corresponding to the car seat. The armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled according to the convenient retrieval position corresponding to the car seat to meet the occupant's retrieval needs and ensure the comfort and convenience of the occupant's retrieval process.

[0194] This invention provides a method for controlling a car seat, such as... Figure 4 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0195] S31: When the first seat is occupied and the first door is closed, determine that the occupant's current status is occupied.

[0196] S32: Obtain the target control signal corresponding to the already boarded state;

[0197] S33: If the target control signal is an exit control signal, then based on the occupant identification data, determine the exit convenience position corresponding to the car seat, and based on the exit convenience position, control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work.

[0198] Wherein, step S31 is a specific implementation of step S1, step S32 is a specific implementation of step S2, and step S33 is a specific implementation of step S3.

[0199] As an example, in step S31, the vehicle controller can obtain the first seat state and the first door state corresponding to the current moment. When the first seat state is in the seated state and the first door state is in the closed state, it can be determined that someone is sitting in the seat and the door is closed at the current moment, indicating that the passenger has already sat in the seat. Therefore, it can be determined that the passenger's current state is the seated state.

[0200] The target control signal refers to the signal emitted by the occupant while they are already seated. As an example, the target control signal can be a signal indicating the adjustment of the car seat armrest or seat position, or it can be a signal indicating whether the occupant is preparing to adjust the car seat or to get out of the vehicle.

[0201] As an example, in step S32, if the vehicle controller recognizes the target control signal as an exit signal, it collects occupant identification data through in-vehicle detection equipment. For example, it can collect occupant video data through an in-vehicle camera and identify the occupant video data as occupant identification data. Then, it performs identity verification on the occupant identification data. For example, it can use, but is not limited to, facial recognition technology to identify the occupant identification data and determine the occupant's identity information. Then, it queries the system database based on the identified occupant identity information and matches it with the corresponding convenient exit position in the system database. Next, the vehicle controller controls the armrest adjustment mechanism 2 to adjust the armrest height to a convenient exit position suitable for the occupant, and / or controls the position adjustment mechanism to move the entire car seat to a convenient exit position suitable for the occupant, thereby making it convenient for the occupant to exit and ensuring the comfort and convenience of the occupant's exit.

[0202] In this embodiment, when the first seat is in a occupied state and the first door is in a closed state, the current state of the occupant is determined to be an occupied state. If the acquired target control signal is an exit control signal, the exit convenience position corresponding to the car seat is determined according to the occupant identification data. Based on the exit convenience position, the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to work so that the armrest height and / or seat position match the occupied state, meet the occupant's seating needs, and ensure the comfort and convenience of the occupant when sitting.

[0203] This invention provides a method for controlling a car seat, such as... Figure 5 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0204] S41: When the first seat is occupied and the first door is closed, determine that the occupant's current status is occupied.

[0205] S42: Obtain the status of the second seat corresponding to the already occupied state;

[0206] S43: If the second seat is in an unoccupied state, then based on the occupant identification data, determine the corresponding convenient exit position of the car seat, and based on the convenient exit position, control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work.

[0207] Wherein, step S41 is a specific implementation of step S1, step S42 is a specific implementation of step S2, and step S43 is a specific implementation of step S3.

[0208] As an example, step S41 is the same as step S31 above, and will not be repeated here to avoid repetition.

[0209] The second seat status is used to assess whether the occupants are ready to get off the vehicle at the current moment.

[0210] As an example, in step S42, when the vehicle controller determines that the occupant's current state is "already seated", it needs to collect the state of the second seat corresponding to the "already seated" state in order to assess whether the occupant is ready to get off the vehicle based on the state of the second seat, so as to make adaptive adjustments.

[0211] As an example, in step S43, when the vehicle controller detects that the second seat is unoccupied, it determines that the occupant is preparing to get off the vehicle. It then collects occupant identification data using in-vehicle detection equipment, such as in-vehicle camera footage, and identifies this footage as occupant identification data. Next, it performs identity verification on the occupant identification data, for example, using, but not limited to, facial recognition technology, to obtain occupant identification information. Then, it queries the system database based on the identified occupant identity information to determine the convenient exit position corresponding to the car seat. Following this, the vehicle controller controls the armrest adjustment mechanism 2 to adjust the armrest height to a convenient exit position for the occupant, and / or controls the position adjustment mechanism to operate based on the convenient exit position, thereby controlling the entire car seat to move to a convenient exit position for the occupant, thus facilitating exit and ensuring the comfort and convenience of the occupant.

[0212] In this embodiment, when the first seat is occupied and the first door is closed, the occupant's current state is determined to be occupied. If the second seat is unoccupied, the corresponding convenient exit position for the car seat is determined based on the occupant identification data. Based on this convenient exit position, the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to operate. This ensures that the armrest height and / or seat position match the current time, meeting the occupant's exit needs and guaranteeing the comfort and convenience of the exit process.

[0213] This invention provides a method for controlling a car seat, such as... Figure 6 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0214] S51: When the first seat is occupied and the first door is closed, determine that the occupant's current status is occupied.

[0215] S52: Obtain occupant identification data corresponding to the already boarded status;

[0216] S53: Based on the occupant identification data, determine the corresponding posture comfort position of the car seat, and based on the posture comfort position, control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work.

[0217] Wherein, step S51 is a specific implementation of step S1, step S52 is a specific implementation of step S2, and step S53 is a specific implementation of step S3.

[0218] As an example, step S51 is the same as step S31 above, and will not be repeated here to avoid repetition.

[0219] As an example, in step S52, when the vehicle controller determines that the occupant's current state is "already seated," the in-vehicle detection device identifies the occupant and obtains their identity information. In this example, the vehicle controller collects occupant identification data through the in-vehicle detection device. For example, it can collect occupant video data through an in-vehicle camera and identify this video data as occupant identification data. Then, it performs identity verification on the occupant identification data, for example, using, but not limited to, facial recognition technology, to obtain occupant identification information.

[0220] As an example, in step S53, the vehicle controller queries the system database based on the identified occupant identity information, matches the current posture comfort position of the occupant in the system database, and thus determines the posture comfort position of the car seat. Subsequently, based on the collected occupant human body information, the posture comfort position is determined.

[0221] In this embodiment, when the first seat is in a occupied state and the first door is in a closed state, the current state of the occupant is determined to be an occupied state. Based on the occupant identification data corresponding to the occupied state, the corresponding posture comfort position of the car seat is determined. Based on the posture comfort position, the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to work so that the armrest height and / or seat position match the occupied state, meet the occupant's sitting needs, and ensure the comfort and convenience of the occupant when sitting.

[0222] In one embodiment, step S53, determining the corresponding posture comfort position of the car seat based on occupant identification data, includes:

[0223] S531: Determine the comfortable position of the first armrest based on the change in headrest height before and after backrest adjustment.

[0224] S532: Determine the comfortable position of the second armrest based on the change in the occupant's eye position before and after seat adjustment.

[0225] S533: Determine the corresponding posture comfort position of the car seat based on the comfort position of the first armrest and / or the comfort position of the second armrest.

[0226] The first armrest comfort position refers to the comfortable posture position for the occupant when the headrest height changes with the backrest angle while the occupant is seated.

[0227] The second armrest comfort position refers to the comfortable posture position for the occupant when the seat angle changes as the occupant is seated.

[0228] As an example, in step S531, if the pressure value detected by the armrest pressure sensor at the current moment is not within the system's preset range, and the vehicle controller detects that the occupant is using the backrest adjustment, the vehicle controller collects the Hall signal count of the backrest drive motor before and after the backrest adjustment, and queries the system database based on the occupant identification information and headrest height change value determined by the occupant identification data collected by the in-vehicle camera or radar. The armrest comfort position that matches the occupant identification information and headrest height change value in the system database is determined as the first armrest comfort position.

[0229] As an example, in step S532, if the pressure value detected by the armrest pressure sensor at the current moment is not within the system's preset range, and the vehicle controller detects that the occupant is using seat adjustment, after collecting the Hall signal count of the seat drive motor before and after seat adjustment, the vehicle controller queries the system database based on the occupant identification information and the change value of the human eye position determined by the occupant identification data collected by the in-vehicle camera or radar. The armrest comfort position that matches the occupant identification information and the change value of the human eye position in the system database is determined as the second armrest comfort position.

[0230] As an example, in step S533, if the pressure value detected by the armrest pressure sensor at the current moment is not within the system's preset range, the vehicle controller can determine the first armrest comfort position as the corresponding posture comfort position of the car seat when it detects that the occupant is using backrest adjustment; when it detects that the occupant is using seat adjustment, it can determine the second armrest comfort position as the corresponding posture comfort position of the car seat; when it detects that the occupant is using both backrest and seat adjustment simultaneously, the posture comfort position of the car seat can be determined based on the first and second armrest comfort positions. For example, the average of the first and second armrest comfort positions can be calculated, and the average of the two can be determined as the armrest height that needs to be adjusted, thus determining it as the corresponding posture comfort position of the car seat, thereby ensuring the occupant's comfort and convenience.

[0231] In this embodiment, based on the change in headrest height before and after backrest adjustment, or the change in eye position before and after seat adjustment, the system database is matched to determine the first and / or second comfortable armrest positions. Based on these comfortable positions, the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to match the armrest height and / or seat position to the current state, meeting the occupant's seating needs and ensuring comfort and convenience.

[0232] This invention provides a method for controlling a car seat, such as... Figure 7 As shown, the automotive seat control method includes the following steps performed by the on-board controller:

[0233] S61: When the first seat is occupied and the first door is closed, determine that the occupant's current status is occupied.

[0234] S62: Obtain the attitude adjustment signal corresponding to the already mounted state;

[0235] S63: Based on the posture adjustment signal, determine the corresponding posture comfort position of the car seat, and control the armrest adjustment mechanism 2 and / or the position adjustment mechanism to work based on the posture comfort position.

[0236] Wherein, step S61 is a specific implementation of step S1, step S62 is a specific implementation of step S2, and step S63 is a specific implementation of step S3.

[0237] As an example, step S61 is the same as step S31 above, and will not be repeated here to avoid repetition.

[0238] As an example, in step S62, when the vehicle controller determines that the occupant is currently in a seated state, it collects a posture adjustment signal to assess whether the car seat has reached a comfortable posture position based on the posture adjustment signal, so as to make adaptive adjustments.

[0239] As an example, in step S63, the vehicle controller matches the current occupant's comfortable posture position in the system database according to the received posture adjustment signal, thereby determining the comfortable posture position of the car seat so that its comfortable posture position can be determined later based on the posture adjustment signal.

[0240] In this embodiment, when the first seat is in an occupied state and the first door is in a closed state, the occupant's current state is determined to be "occupied." Based on the posture adjustment signal corresponding to the "occupied" state, the corresponding comfortable posture position of the car seat is determined. Based on the comfortable posture position, the armrest adjustment mechanism 2 and / or the position adjustment mechanism are controlled to operate. This ensures that the armrest height and / or seat position match the "occupied" state, meeting the occupant's seating needs and guaranteeing the occupant's comfort and convenience.

[0241] In one embodiment, the data to be identified includes occupant identification data;

[0242] like Figure 8 As shown, step S3, which involves determining the target location corresponding to the car seat based on the data to be identified, includes:

[0243] S71: Obtain occupant identity information based on occupant identification data;

[0244] S72: Based on the occupant identity information query system database, obtain the target location corresponding to the occupant identity information and determine it as the target location corresponding to the car seat.

[0245] Among them, passenger identity information refers to the passenger identity information identified by the vehicle controller at the current moment.

[0246] As an example, in step S71, the vehicle controller collects occupant identification data through in-vehicle detection equipment. For example, occupant video data can be collected through an in-vehicle camera, and the occupant video data is identified as occupant identification data. Then, the occupant identification data is used for identity verification. For example, but not limited to, facial recognition technology can be used to identify the occupant identification data and obtain occupant identification information.

[0247] As an example, in step S72, the vehicle controller queries the system database based on the collected occupant identity information to obtain the armrest comfort position and / or seat comfort position corresponding to the occupant identity information, and then determines the target position corresponding to the car seat based on the collected occupant identity information.

[0248] In this embodiment, passenger identity information is obtained based on passenger identification data. The system database is then queried based on the passenger identity information to obtain the armrest comfort position and / or seat comfort position corresponding to the passenger identity information. This controls the operation of the armrest adjustment mechanism 2 and / or the position adjustment mechanism to ensure the comfort and convenience of passengers when riding or getting off the vehicle.
