[0056] The technical solutions of the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0057] The embodiments of the present application provide a control method of an automobile seat. The automobile seat comprises a seat cushion, a backrest, an armrest and a vehicle-mounted controller. The backrest is rotationally connected with the seat cushion, the armrest is rotationally connected with the backrest, and the vehicle-mounted controller is used to control the armrest of the automobile seat based on a target working mode of the automobile seat. Figure 1 As shown in the figure, the control method of the automobile seat comprises the following steps executed by the vehicle-mounted controller:

[0058] S101: acquiring current vehicle data;

[0059] S102: monitoring the seating state of the automobile seat to obtain a first seating state monitoring result corresponding to the automobile seat;

[0060] S103: Determine the target working mode of the automobile seat based on the current vehicle data and the first occupancy state monitoring result.

[0061] S104: Control the armrest working of the automobile seat based on the target working mode of the automobile seat.

[0062] The current vehicle data refers to the vehicle data collected at the current time. As an example, the current vehicle data includes the current vehicle state and / or the target signal, i.e., the current vehicle data can only include the current vehicle state, can only include the target signal, or can include both the current vehicle state and the target signal. The current vehicle state refers to the working state of the vehicle at the current time. The target signal refers to the signal received by the vehicle controller at the current time.

[0063] As an example, in step S101, the vehicle controller can obtain the current vehicle data including the current vehicle state and / or the target signal through a bus or wireless communication, so as to evaluate and determine the target working mode of the automobile seat based on the current vehicle state and / or the target signal.

[0064] The occupancy state monitoring refers to a process for monitoring whether the automobile seat is occupied by a passenger. The first occupancy state monitoring result refers to the result of real-time monitoring whether the automobile seat is occupied by a passenger at the current time, specifically refers to the monitoring result before the target working mode is determined, including the passenger-occupied state and the non-passenger-occupied state.

[0065] As an example, in step S102, the vehicle controller can call the monitoring device arranged on the automobile seat to monitor the occupancy state of the automobile seat, so as to determine whether the automobile seat is occupied by a passenger, and obtain any one of the passenger-occupied state and the non-passenger-occupied state, so as to evaluate and determine the target working mode of the automobile seat based on the first occupancy state monitoring result. For example, the vehicle controller can receive the sensing signal collected by the weight sensor arranged on the automobile seat through a bus, or receive the camera data collected by the camera arranged opposite to the automobile seat through a bus, or receive the diaphragm data collected by the diaphragm collecting device arranged opposite to the automobile seat through a bus, to determine the first occupancy state monitoring result corresponding to the automobile seat.

[0066] The target working mode of the automobile seat refers to a working mode required to be switched into by the automobile seat at the current time. As an example, the target working mode can be any one of an adaptive mode, a welcome mode, a send-off mode, and an interesting mode. The adaptive mode refers to a mode in which the armrest is adjusted adaptively, i.e., after the backrest is adjusted, the armrest is adjusted adaptively to keep a comfortable position with the horizontal plane. The welcome mode refers to a mode in which a passenger is welcomed. The send-off mode refers to a mode in which a passenger is sent off. The interesting mode refers to a mode in which the armrest is controlled to rotate with a melody or meet a certain interesting requirement.

[0067] As an example, in step S103, after obtaining the current vehicle data and the first seat state monitoring result, the vehicle-mounted controller can compare the current vehicle data and the first seat state monitoring result with the evaluation conditions corresponding to the plurality of working modes configured in advance, and if the current vehicle data and the first seat state monitoring result meet the evaluation condition corresponding to a working mode, the working mode corresponding to the evaluation condition is determined as the target working mode of the automobile seat. In this example, the target working mode of the automobile seat can be any one of the adaptive mode, the welcome mode, the send-off mode, and the interesting mode.

[0068] As an example, in step S104, after determining the target working mode of the automobile seat, the vehicle-mounted controller can control the armrest of the automobile seat to work according to the control logic corresponding to the target working mode, so as to meet the seat experience requirement corresponding to the target working mode. For example, when the target working mode is the adaptive mode, the angle of the armrest of the automobile seat is controlled to change with the angle of the backrest, so as to ensure the angle corresponding to the comfortable position with the horizontal plane, thereby meeting the comfort requirement. For another example, when the target working mode is the welcome mode or the send-off mode, the armrest of the automobile seat is controlled to open upward, so as to facilitate the passenger to get on or off the automobile seat, thereby meeting the convenience requirement. For another example, when the target working mode is the interesting mode, the armrest is controlled to rotate with a melody or meet a certain interesting requirement, thereby meeting the entertainment requirement.

[0069] As an example, when the target working mode of the automobile seat is the welcome mode or the send-off mode, the passenger needs to get on or off the automobile seat, and in order to further facilitate the travel, when the automobile seat is installed on the vehicle body through a slide rail and the vehicle-mounted controller is connected to the slide rail, the slide rail can be controlled to move to a specific position at the same time, so as to facilitate the passenger to get on or off the automobile seat.

[0070] In this embodiment, the target working mode of the automobile seat is determined according to the current vehicle data and the first seat state monitoring result of the automobile seat, the armrest of the automobile seat can be quickly switched to work in the target working mode, so that the armrest can be used in more scenes in addition to the basic scene of the armrest, the requirement of diversified use scenes is met, and the seat experience of the passenger is improved.

[0071] In an embodiment, the current vehicle data comprises a current vehicle state and a target signal;

[0072] The step S103, i.e. determining the target working mode based on the current vehicle data and the first occupancy state monitoring result, comprises:

[0073] If the current vehicle state is an ACC state or an ON state, the target signal is a signal formed in response to a backrest adjustment instruction for backrest angle adjustment operation, and the first occupancy state monitoring result is an occupancy state with a passenger, the adaptive mode is determined as the target working mode.

[0074] The ACC state is an Accessory state, i.e. except for providing power supply to the vehicle accessory (such as audio-visual system, instrument light, light), other modules are not provided with power supply (glass lifting, power sunroof cannot be actuated). The ON state is that all modules are in the power-on state except that the engine is not started.

[0075] The backrest adjustment instruction is an instruction for adjusting the backrest angle. As an example, the backrest adjustment instruction can be input through a physical button, or can be input through voice or gesture and other interactive modes. The target signal is a signal formed in response to the backrest adjustment instruction for backrest angle adjustment operation, which is a signal output based on the backrest adjustment instruction for controlling the automobile seat to adjust the backrest angle forward or backward.

[0076] As an example, when the vehicle enters the ACC state or the ON state, the vehicle controller can determine that the vehicle is not started, and the automobile seat can be adjusted to meet the first evaluation condition for adaptive angle adjustment of the automobile seat. When the target signal is a signal formed in response to the backrest adjustment instruction for backrest angle adjustment operation, it can be determined that the automobile seat has completed the operation of adjusting the backrest angle forward or backward, at this time, the angle of the backrest relative to the horizontal plane changes, and since the armrest is generally fixedly installed on one side of the backrest, the angle of the armrest relative to the horizontal plane also changes, which is easy to make the armrest deviate from the comfortable position, and meets the second evaluation condition for adaptive angle adjustment of the automobile seat. When the first occupancy state monitoring result is an occupancy state with a passenger, it indicates that there is a passenger sitting on the automobile seat at the current time, and it is necessary to adjust the angle of the armrest, and it can be determined that the third evaluation condition for adaptive angle adjustment is met. Therefore, when the current vehicle state is the ACC state or the ON state, the target signal is a signal formed in response to the backrest adjustment instruction for backrest angle adjustment operation, and the first occupancy state monitoring result is an occupancy state with a passenger, the adaptive mode is determined as the target working mode, so as to control the armrest of the automobile seat to perform adaptive angle adjustment, so that it remains in a comfortable position with the horizontal plane, to meet the comfort requirement.

[0077] AsFigure 2 As shown, step S104, i.e. controlling the armrest work of the car seat based on the target working mode, comprises:

[0078] S201: If the target working mode is the adaptive mode, obtaining the backrest adjustment angle and the backrest adjustment direction corresponding to the backrest adjustment instruction;

[0079] S202: Controlling the armrest to adjust the angle in the direction opposite to the backrest adjustment direction, and stopping the adjustment when the armrest adjustment angle is consistent with the backrest adjustment angle.

[0080] As an example, in step S201, the vehicle-mounted controller can obtain the backrest adjustment angle and the backrest adjustment direction corresponding to the backrest adjustment instruction when it is determined that the target working mode is the adaptive mode. The backrest adjustment angle refers to the angle between the starting position and the ending position of the backrest adjustment. The backrest adjustment direction refers to the direction of the backrest adjustment, for example, the backrest adjustment direction can be forward adjustment or backward adjustment.

[0081] As an example, in step S201, after the vehicle-mounted controller determines the backrest adjustment angle and the backrest adjustment direction, it can control the armrest to adjust the angle in the direction opposite to the backrest adjustment direction. Specifically, it can control the armrest motor connected to the armrest to adjust the rotation direction, so that it rotates in the direction opposite to the backrest adjustment direction, thereby achieving the adjustment of the armrest angle. During the adjustment of the armrest angle, the adjustment angle of the armrest needs to be monitored in real time to determine whether the armrest adjustment angle is consistent with the backrest adjustment angle. If they are consistent, the adjustment of the armrest angle is stopped, so that the angle between the armrest and the horizontal plane returns to the angle before the backrest adjustment, so as to control the armrest to adjust the angle adaptively according to the backrest adjustment angle.

[0082] Wherein, the armrest adjustment angle refers to the angle monitored in real time after the armrest starts to adjust the angle.

[0083] In order to maintain the angle between the armrest and the horizontal plane at a comfortable position, the backrest adjustment angle is determined as the target armrest angle that needs to be controlled after the backrest adjustment. When the backrest adjustment direction is backward tilting, the armrest angle assembled on the backrest tilts upward and away from the comfortable position. At this time, the armrest needs to be controlled to rotate downward to achieve the adjustment of the armrest angle. When the armrest adjustment angle is consistent with the backrest adjustment angle, the adjustment is stopped, and it can be determined that the armrest returns to the comfortable position. Conversely, when the backrest adjustment direction is forward tilting, the armrest angle assembled on the backrest also tilts downward and away from the comfortable position. At this time, the armrest needs to be controlled to rotate upward to achieve the adjustment of the armrest angle. When the armrest adjustment angle is consistent with the backrest adjustment angle, it can be determined that the armrest returns to the comfortable position.

[0084] Understandably, when the car seat enters the adaptive mode, the armrest angle can be adjusted when the backrest angle is adjusted, so that the angle between the armrest and the horizontal plane remains unchanged, that is, the armrest is kept in a comfortable position, thereby effectively improving the comfort of the armrest after the backrest is adjusted.

[0085] In an embodiment, as Figure 1 , the car seat further comprises a backrest motor and an armrest motor in communication with the vehicle controller; the backrest motor is used to drive the backrest to rotate relative to the seat cushion, and the backrest motor is provided with a first Hall sensor for collecting a backrest Hall signal; the armrest motor is used to drive the armrest to rotate relative to the backrest, and the armrest motor is provided with a second Hall sensor for collecting an armrest Hall signal;

[0086] In step S201, the backrest adjustment angle corresponding to the backrest adjustment instruction is obtained, including:

[0087] The backrest measured signal number corresponding to the backrest Hall signal is obtained, and the backrest adjustment angle is determined according to the backrest measured signal number and the backrest rotation angle corresponding to one rotation of the backrest motor;

[0088] In step S202, the armrest is controlled to adjust the angle in the direction opposite to the backrest adjustment direction, and the adjustment is stopped when the armrest adjustment angle is consistent with the backrest adjustment angle, including:

[0089] S2021: determining the armrest target signal number corresponding to the armrest according to the backrest adjustment angle and the armrest rotation angle corresponding to one rotation of the armrest motor;

[0090] S2022: controlling the armrest to rotate in the direction opposite to the backrest adjustment direction, and stopping the rotation when the armrest measured signal number corresponding to the armrest Hall signal reaches the armrest target signal number.

[0091] Wherein, the backrest motor is a motor for controlling the rotation of the backrest relative to the seat cushion. The first Hall sensor is a Hall sensor arranged in the backrest motor. The backrest Hall signal refers to the Hall signal collected by the first Hall sensor related to the position of the backrest.

[0092] Wherein, the armrest motor is a motor for controlling the rotation of the armrest relative to the backrest. The second Hall sensor is a Hall sensor arranged in the armrest motor. The armrest Hall signal refers to the Hall signal collected by the second Hall sensor related to the armrest.

[0093] As an example, in step S201, when the vehicle-mounted controller determines that the target working mode is the adaptive mode, the vehicle-mounted controller can obtain the backrest measured signal number corresponding to the backrest adjustment instruction and the backrest adjustment direction. The backrest measured signal number refers to the number of backrest Hall signals formed between the start time and the end time of the backrest adjustment. The backrest adjustment direction refers to the direction of the backrest adjustment. For example, the backrest adjustment direction can be forward adjustment or backward adjustment.

[0094] As an example, in step S201, when the vehicle-mounted controller determines the backrest measured signal number corresponding to the current backrest adjustment, the vehicle-mounted controller determines the backrest adjustment angle corresponding to the current backrest adjustment. The backrest adjustment angle is the product of the backrest rotation angle corresponding to one rotation of the backrest motor and the backrest measured signal number. Generally, the backrest motor is provided with a first Hall sensor. The first Hall sensor outputs a backrest Hall signal for each rotation of the backrest motor. The product of the backrest measured signal number corresponding to all backrest Hall signals output by the first Hall sensor and the backrest rotation angle corresponding to each backrest measured signal number is determined as the backrest adjustment angle corresponding to the current backrest adjustment.

[0095] As an example, in step S202, after the vehicle-mounted controller determines the backrest adjustment angle, the vehicle-mounted controller can determine the armrest target signal number corresponding to the armrest according to the backrest adjustment angle and the armrest rotation angle corresponding to one rotation of the armrest motor. Specifically, the quotient of the backrest adjustment angle and the armrest rotation angle corresponding to one rotation of the armrest motor is determined as the armrest target signal number corresponding to the armrest. The armrest target signal number can be understood as the signal number of the armrest angle adjustment, and can be understood as the number of rotations of the armrest motor that needs to be controlled. For example, assuming that the backrest rotation angle corresponding to one rotation of the backrest motor is Va, the backrest measured signal number is Sa, the armrest rotation angle corresponding to one rotation of the armrest motor is Vb, and the armrest target signal number is Sb. In order to realize the consistency of the backrest adjustment angle and the armrest adjustment angle, it is necessary to ensure that Sa*Va=Sb*Vb, that is, Sb=Sa*(Va / Vb), and Va / Vb is the rotation ratio of the two.

[0096] In this example, after determining the target signal number corresponding to the armrest, the vehicle controller can control the armrest to adjust the angle in the opposite direction of the backrest adjustment direction. Specifically, the vehicle controller can control the armrest motor to adjust the rotation direction of the armrest motor, so that the armrest motor rotates in the opposite direction of the backrest adjustment direction, thereby adjusting the angle of the armrest. During the adjustment of the angle of the armrest, the number of armrest measured signals corresponding to the armrest Hall signals needs to be counted in real time, and it is determined whether the number of armrest measured signals is consistent with the target signal number of the armrest. If the two are consistent, the adjustment of the angle of the armrest is stopped, and the angle between the armrest and the horizontal plane is restored to the angle before the adjustment of the angle of the backrest, so as to realize the self-adaptive adjustment of the angle of the armrest according to the adjustment of the angle of the backrest. The number of armrest measured signals herein can be understood as the number of armrest Hall signals counted in real time, which refers to the number of armrest Hall signals monitored after the armrest starts to adjust the angle in the opposite direction.

[0097] In an embodiment, the current vehicle data includes a target signal;

[0098] Step S103, i.e., determining a target working mode based on the current vehicle data and the first occupancy state monitoring result, includes:

[0099] If the target signal is a signal formed in response to an outside door opening instruction for door opening operation, and the first occupancy state monitoring result is a no-occupant occupancy state, the target working mode is determined as a welcome mode.

[0100] The outside door opening instruction refers to a door opening instruction given by an occupant outside the vehicle. As an example, the outside door opening instruction can be input through a physical button, for example, operating a door handle or an electric door opening button, or can be input through voice or other interactive methods such as gestures. The target signal is a signal formed after the vehicle door is opened based on the outside door opening instruction.

[0101] As an example, when the target signal is a signal formed in response to an outside door opening instruction for door opening operation, the vehicle controller can determine that the vehicle has controlled the vehicle door to open based on the received outside door opening instruction. At this time, it is most likely that the occupant enters the vehicle from the outside and sits on the vehicle seat, so it can be determined that the first evaluation condition of the welcome mode is met. When the first occupancy state monitoring result is a no-occupant occupancy state, it indicates that there is no occupant sitting on the vehicle seat at the current time, which indicates that the occupant has not entered the vehicle from the outside and sat on the vehicle seat. It can be determined that the second evaluation condition of the welcome mode is met. In this example, when the target signal is a signal formed in response to an outside door opening instruction for door opening operation, and the first occupancy state monitoring result is a no-occupant occupancy state, the target working mode is determined as a welcome mode, so as to control the armrest of the vehicle seat to open upward during the process that the occupant enters the vehicle seat from the outside, thereby facilitating the entry of the occupant into the vehicle seat and meeting the convenience requirement of entry and exit.

[0102] In an embodiment, as shown in Figure 3 Step S104, i.e. controlling the armrest of the car seat based on the target working mode, includes:

[0103] S301: If the target working mode is the welcome mode, the armrest of the car seat is controlled to open upward;

[0104] S302: The seating state of the car seat is monitored to obtain a second seating state monitoring result corresponding to the car seat;

[0105] S303: If the second seating state monitoring result is the passenger seating state, the armrest of the car seat is reset downward.

[0106] As an example, in step S301, when the vehicle-mounted controller determines that the target working mode is the welcome mode, the armrest of the car seat can be controlled to open upward during the door opening operation in response to receiving the door opening instruction outside the vehicle, so as to facilitate the passenger to enter the car seat and sit down, thereby meeting the convenience requirement of entering and exiting.

[0107] Further, the vehicle-mounted controller can determine the target seat that needs to perform the welcome operation and the target armrest that needs to perform the welcome operation according to the target door corresponding to the door opening instruction outside the vehicle. In this example, the vehicle-mounted controller can determine the car seat closest to the target door as the target seat, or can determine all car seats in the passenger cabin corresponding to the target door as the target seat. When the vehicle-mounted controller determines the target seat, the armrests passing through the entering and exiting route between the target seat and the target door can be determined as the target armrest, so as to control the target armrest on the target seat to open upward in the welcome mode, thereby facilitating the passenger to enter the vehicle from the opened door and sit down.

[0108] Further, when the car seat is assembled on the vehicle body through the slide rail assembly, and the vehicle-mounted controller communicates with the slide rail assembly, when the vehicle-mounted controller determines that the target working mode is the welcome mode, the vehicle-mounted controller needs to control the slide rail assembly to drive the car seat to slide backward to a first position, and control the armrest of the car seat to open upward, so as to facilitate the passenger to enter the seat and sit down, thereby meeting the convenience requirement of entering and exiting. The first position can be a default position pre-set by the system, or can be a seating position matched according to the recognized passenger information, which can be determined autonomously according to actual requirements.

[0109] Among them, the second seating state monitoring result refers to the result of monitoring whether there is a passenger on the car seat after controlling the armrest according to the target working mode. The second seating state monitoring result refers to the monitoring result after determining the target working mode, including the passenger seating state and the non-passenger seating state.

[0110] As an example, in step S302, after the armrest of the car seat is controlled to open upward, the vehicle-mounted controller can call the monitoring device arranged on the car seat to monitor the occupancy state of the car seat to determine whether the car seat is occupied by a passenger, and obtain any one of the monitoring results of the passenger-occupied state and the passenger-unoccupied state, so as to monitor whether the passenger entering from outside the vehicle is seated on the car seat based on the second occupancy state monitoring result.

[0111] As an example, in step S303, when the second occupancy state monitoring result is the passenger-occupied state, it indicates that the passenger enters the vehicle from outside and is seated on the car seat, at this time, the armrest of the car seat is controlled to reset downward to facilitate the passenger to put his hands on the armrest and improve the passenger's riding experience. In this example, the vehicle-mounted controller controls the armrest of the car seat to reset downward to a target angle, which can be a pre-set initial angle or a specific angle matched according to the recognized passenger information, and can be determined autonomously according to actual needs.

[0112] Further, when the target working mode is the welcome mode, the armrest of the car seat is opened upward, and the second occupancy state monitoring result is the passenger-occupied state, the vehicle-mounted controller can control the slide rail assembly to drive the car seat to slide forward to a second position, and control the armrest of the car seat to reset downward to facilitate the passenger to put his hands on the armrest and improve the passenger's riding experience. The second position can be a default position pre-set by the system or a seating position matched according to the recognized passenger information, and can be determined autonomously according to actual needs.

[0113] In an embodiment, the current vehicle data includes a target signal;

[0114] In step S103, the target working mode is determined based on the current vehicle data and the first occupancy state monitoring result, including:

[0115] When the target signal is a signal formed in response to a door opening operation of an in-vehicle door opening instruction, and the first occupancy state monitoring result is the passenger-occupied state, the target working mode is determined as the guest sending mode.

[0116] The in-vehicle door opening instruction refers to the door opening instruction given by the passenger in the vehicle. As an example, the in-vehicle door opening instruction can be input through a physical button, for example, by operating an in-vehicle unlocking button, or can be input through voice or other interactive methods such as gestures. The target signal is a signal formed after the vehicle door is opened in response to the in-vehicle door opening instruction.

[0117] As an example, the vehicle controller can determine that the vehicle has controlled the door to open based on the target signal being a signal formed in response to the door opening instruction, and that the passenger has already sat on the seat and intends to open the door and get off the seat, so as to determine that the first evaluation condition of the drop-off mode is met. When the first occupancy state monitoring result is that the passenger is sitting on the seat, it indicates that the passenger is sitting on the seat and intends to get off the seat, so as to determine that the second evaluation condition of the drop-off mode is met. In this example, when the target signal is a signal formed in response to the door opening instruction, and the first occupancy state monitoring result is that the passenger is sitting on the seat, the target working mode is determined to be the drop-off mode, so as to control the armrest of the seat to open upward during the passenger getting off the seat, to facilitate the passenger getting off the seat and meet the convenience requirement of getting in and out.

[0118] In an embodiment, as shown in FIG. 1, the step S104 of controlling the armrest of the seat based on the target working mode comprises: Figure 4

[0119] S401: If the target working mode is the drop-off mode, control the armrest of the seat to open upward.

[0120] S402: Monitor the occupancy state of the seat to obtain a second occupancy state monitoring result corresponding to the seat.

[0121] S403: If the second occupancy state monitoring result is that no passenger is sitting on the seat, control the armrest of the seat to reset downward.

[0122] As an example, in step S401, when the vehicle controller determines that the target working mode is the drop-off mode, the vehicle controller can control the armrest of the seat to open upward during the door opening operation in response to the received door opening instruction, to facilitate the passenger getting off the seat and meet the convenience requirement of getting in and out.

[0123] Further, the vehicle controller can determine the target seat on which the drop-off operation needs to be performed and the target armrest on which the drop-off operation needs to be performed according to the target door corresponding to the door opening instruction. In this example, the vehicle controller can determine the seat closest to the target door as the target seat, or can determine all the seats in the passenger cabin corresponding to the target door as the target seat. When the vehicle controller determines the target seat, the vehicle controller can determine the armrests through which the access route between the target seat and the target door passes as the target armrest, so as to control the target armrest on the target seat to open upward in the drop-off mode, to facilitate the passenger getting off the target seat.

[0124] ​Further, when the automobile seat is assembled on the automobile body through the slide rail assembly, and the vehicle controller communicates with the slide rail assembly, the vehicle controller controls the slide rail assembly to work, and when the target working mode is determined as the guest sending mode, the vehicle controller needs to control the slide rail assembly to drive the automobile seat to slide backward to the first position, and control the armrest of the automobile seat to open upward, so as to facilitate the passenger to get off the seat, so as to meet the convenience requirement of getting in and out. The first position can be a default position pre-set by the system, or can be a seat position matched according to the recognized passenger information, and can be determined autonomously according to actual requirements.

[0125] The second seat state monitoring result refers to a result of monitoring whether the automobile seat has a passenger after the armrest is controlled to work according to the target working mode. The second seat state monitoring result refers to a monitoring result after the target working mode is determined, and includes two results of a passenger state and a non-passenger state.

[0126] As an example, in step S402, after the vehicle controller controls the armrest of the automobile seat to open upward, the monitoring device arranged on the automobile seat can be called to monitor the seat state of the automobile seat, so as to determine whether the automobile seat has a passenger, and to obtain any one of the monitoring results of the passenger state and the non-passenger state, so as to monitor whether the passenger gets off the automobile seat based on the second seat state monitoring result.

[0127] As an example, in step S403, when the second seat state monitoring result is the non-passenger state, it indicates that the passenger gets off the automobile seat, and at this time, the armrest of the automobile seat is reset downward to facilitate other passengers to get on. In this example, the vehicle controller controls the armrest of the automobile seat to reset to the target angle, and the target angle can be a pre-set initial angle.

[0128] Further, when the target working mode is the guest sending mode, the armrest of the automobile seat is opened upward, and the second seat state monitoring result is the non-passenger state, the vehicle controller can control the slide rail assembly to drive the automobile seat to slide forward to the second position, and control the armrest of the automobile seat to reset downward. The second position can be a default position pre-set by the system, and can be determined autonomously according to actual requirements.

[0129] In an embodiment, the current vehicle data includes a current vehicle state;

[0130] Step S103, that is, determining the target working mode based on the current vehicle data and the first seat state monitoring result, includes:

[0131] If the current vehicle state is the exhibition state or the non-driving state, and all the first seat state monitoring results are the non-passenger state, the interesting mode is determined as the target working mode.

[0132] The "show car state" refers to the state in which the car is in display mode. This is achieved by disabling the car's power unit and air conditioning through software, without affecting the large-screen interactive display and other functions, ensuring that the car can be displayed stationary for a long time. The "non-driving state" refers to the state in which the car is not in driving.

[0133] As an example, when the current vehicle state is a display vehicle or a non-driving state, the onboard controller can determine that the vehicle is stationary and thus satisfy the first evaluation condition for the fun mode. If the first seating state monitoring result is a no-occupant state, indicating that no occupants are currently seated in the vehicle seat and no occupants have yet to enter the vehicle from outside and sit in the vehicle seat, the second evaluation condition for the fun mode can be determined to be satisfied. In this example, when the current vehicle state is a display vehicle or a non-driving state, and all first seating state monitoring results are no-occupants, the target operating mode is determined to be the fun mode. This allows the vehicle seat armrests to rotate to a melody or perform certain fun movements when no occupants are seated, thereby satisfying their entertainment needs.

[0134] In one embodiment, the fun mode includes a lucky cat mode, a joy mode, and a rhythm mode;

[0135] like Figure 5 As shown, step S104, i.e., controlling the operation of the armrest of the car seat based on the target operating mode of the car seat, includes:

[0136] S501: If the target working mode is the lucky cat mode, control the armrest on one side to swing up and down at a fixed frequency;

[0137] S502: If the target working mode is the joy mode, control the armrests on both sides to swing up and down in different directions;

[0138] S503: If the target working mode is the rhythmic mode, the armrest is controlled to swing according to the music melody.

[0139] As an example, in step S501, when the vehicle-mounted controller determines that the target working mode is the fun mode, and according to the pre-setting corresponding to the fun mode, determines that the fun mode is the fortune cat mode, that is, when the target working mode is determined to be the fortune cat mode, it can control the single-side armrest of one or more car seats to swing up and down at a fixed frequency, so that it looks like a fortune cat, meeting entertainment needs.

[0140] As an example, in step S502, when the vehicle controller determines that the target working mode is the fun mode, and according to the pre-setting corresponding to the fun mode, determines that the fun mode is the joy mode, that is, when the target working mode is determined to be the joy mode, the double-sided armrests of one or more car seats can be controlled to swing up and down in different directions, and the swinging frequency of the double-sided armrests can be the same or different to meet entertainment needs.

[0141] As an example, in step S503, the vehicle-mounted controller determines that the target working mode is the fun mode, and according to the pre-setting corresponding to the fun mode, it is determined that the fun mode is the rhythm mode, that is, the target working mode is the rhythm mode, and the single armrest or double armrest of one or more car seats can be controlled to swing according to the pre-set music melody, meeting the entertainment demand.

[0142] In this example, scene expansion can be used to determine fun modes including but not limited to lucky cat mode, happy mode and rhythm mode, so that they are applicable in more scenes, greatly improving the armrest fun and the compatibility with the whole vehicle scene.

[0143] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.

[0144] In an embodiment, a vehicle-mounted controller is provided, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the control method of the car seat in the above embodiment is implemented, for example Figure 1 S101-S104, or Figures 2 to 6 To avoid repetition, details are not repeated here.

[0145] The embodiment of the present application provides a car seat, which includes a seat cushion, a backrest and an armrest, the backrest is rotationally connected with the seat cushion, the armrest is rotationally connected with the backrest, and the vehicle-mounted controller in the above embodiment is further included, and the vehicle-mounted controller is used to control the armrest of the car seat based on the target working mode of the car seat. In this example, the target working mode corresponding to the car seat is determined according to the current vehicle data and the first sitting state monitoring result of the car seat, so that the armrest of the car seat can be quickly switched to work in the target working mode, so that it can be used in more scenes in addition to the basic scene of the armrest, meeting the diversified application scene demand and improving the riding experience of the passenger.

[0146] In an embodiment, the car seat further comprises a backrest motor and an armrest motor in communication with the vehicle controller; the backrest motor is used to drive the backrest to rotate relative to the seat cushion, and the backrest motor is provided with a first Hall sensor for collecting a backrest Hall signal; the armrest motor is used to drive the armrest to rotate relative to the backrest, and the armrest motor is provided with a second Hall sensor for collecting an armrest Hall signal; when the target working mode is the adaptive mode, the vehicle controller is used to obtain a backrest measured signal number corresponding to the backrest Hall signal, determine a backrest adjustment angle and a backrest adjustment direction according to the backrest measured signal number and a backrest rotation angle corresponding to one rotation of the backrest motor, determine an armrest target signal number corresponding to the armrest according to the backrest adjustment angle and an armrest rotation angle corresponding to one rotation of the armrest motor, and control the armrest to rotate in a direction opposite to the backrest adjustment direction and stop rotating when an armrest measured signal number corresponding to the armrest Hall signal reaches the armrest target signal number.

[0147] In the example, when the vehicle controller determines that the target working mode is the adaptive mode, the backrest measured signal number corresponding to the backrest Hall signal can be obtained, and the product of the backrest measured signal number and a backrest rotation angle corresponding to one rotation of the backrest motor can be determined as the backrest adjustment angle and the backrest adjustment direction. Then, the vehicle controller can determine the armrest target signal number corresponding to the armrest according to the backrest adjustment angle and an armrest rotation angle corresponding to one rotation of the armrest motor, specifically, the quotient of the backrest adjustment angle and the armrest rotation angle corresponding to one rotation of the armrest motor is determined as the armrest target signal number corresponding to the armrest. Finally, the vehicle controller can control the armrest to adjust the angle in a direction opposite to the backrest adjustment direction, specifically, the rotation direction of the armrest motor can be adjusted so that it rotates in a direction opposite to the backrest adjustment direction, so as to adjust the angle of the armrest; during the angle adjustment of the armrest, the armrest measured signal number corresponding to the armrest Hall signal needs to be counted in real time, and it is determined whether the armrest measured signal number is consistent with the armrest target signal number; if they are consistent, the angle adjustment of the armrest is stopped, and the angle between the armrest and the horizontal plane is restored to the angle before the backrest adjustment, so as to realize the adaptive angle adjustment of the armrest according to the backrest adjustment angle. The vehicle controller can effectively ensure that the angle of the armrest is adjusted when the backrest angle is adjusted when the car seat enters the adaptive mode, so that the angle between the armrest and the horizontal plane remains unchanged, that is, the armrest remains in a comfortable position, thereby effectively improving the comfort of the armrest after the backrest adjustment.

[0148] For example, Figure 6As shown, the car seat includes a backrest, a backrest framework assembly 610 and an armrest assembly 620, the backrest is assembled on the backrest framework assembly 610, the backrest framework assembly 610 includes a backrest side plate 611 and a backrest motor 612, the backrest motor 612 is internally provided with a first Hall sensor for collecting a backrest Hall signal; the armrest assembly 620 includes an armrest support 621, an armrest motor 622 and an armrest 623, the armrest support 621 is installed on the backrest side plate 611, the armrest motor 622 is assembled on the armrest support 621, the armrest 623 is assembled on the armrest motor 622, the armrest motor 622 is internally provided with a second Hall sensor for collecting an armrest Hall signal; the car seat further includes a vehicle-mounted controller, the vehicle-mounted controller is connected with the first Hall sensor, the second Hall sensor and the armrest motor 622, and is used for controlling the armrest motor 622 to adjust the angle according to the backrest Hall signal and the armrest Hall signal.

[0149] Among them, the backrest side plate 611 refers to the side plate for assembling the backrest, and also refers to the side plate for installing the armrest 623 assembly 620. The backrest motor 612 is a motor for adjusting the relative angle between the backrest and the cushion, and the backrest motor 612 is a device for realizing the angle adjustment of the backrest. The first Hall sensor is a Hall sensor arranged in the backrest motor 612. The backrest Hall signal refers to the Hall signal related to the position of the backrest collected by the first Hall sensor.

[0150] Among them, the armrest support 621 is a support for installing the armrest motor 622. The armrest motor 622 is a motor for controlling the rotation of the armrest 623. The second Hall sensor is a Hall sensor arranged in the armrest motor 622. The armrest Hall signal refers to the Hall signal related to the armrest 623 collected by the second Hall sensor.

[0151] As an example, the armrest support 621 is assembled on the outer side of the backrest side plate 611, for example, the armrest support 621 is welded and fixed on the backrest side plate 611, in this example, the backrest side plate 611 and the armrest support 621 are respectively provided with a first through hole and a second through hole. The armrest motor 622 is placed on the inner side of the backrest side plate 611, and is fixed on the armrest support 621 by using a nut or other connecting piece. The rotating shaft of the armrest motor 622 passes through the first through hole of the backrest side plate 611, the second through hole of the armrest support 621 and the third through hole on the armrest 623, and is fixed by using a nut, so as to realize the connection between the armrest motor 622 and the armrest 623, so that the armrest 623 can rotate around the rotating shaft of the armrest motor 622, so as to adjust the angle of the armrest 623 relative to the backrest, and realize the purpose of adjusting the angle of the armrest 623 by using the armrest motor 622. Further, the armrest 623 assembly 620 further includes an armrest 623 decorative cover arranged on the armrest 623, for covering the internal mounting structure of the armrest 623.

[0152] As an example, when the backrest is angle-adjusted, the armrest 623 needs to be controlled to follow the angle adjustment of the backrest, so that when the armrest 623 and the horizontal plane are at a relative angle that ensures a comfortable position, the vehicle controller can control the armrest motor 622 to work according to the backrest Hall signal collected by the first Hall sensor in real time and the armrest Hall signal collected by the second Hall sensor in real time, so as to adjust the armrest 623 to the angle that ensures the comfortable position with the horizontal plane, so as to avoid that the armrest 623 and the backrest keep a fixed relative angle, so that the armrest 623 is in an uncomfortable position, affecting the riding experience of the occupant.

[0153] As an example, the armrest support 621 is assembled on the outer side of the backrest side plate 611, for example, the armrest support 621 is welded and fixed on the backrest side plate 611, in this example, the backrest side plate 611 and the armrest support 621 are respectively provided with a first through hole and a second through hole. The armrest motor 622 is placed on the inner side of the backrest side plate 611, and is fixed on the armrest support 621 by using a nut or other connecting piece. The rotating shaft of the armrest motor 622 passes through the first through hole of the backrest side plate 611, the second through hole of the armrest support 621 and the third through hole on the armrest 623, and is fixed by using a nut, so as to realize the connection between the armrest motor 622 and the armrest 623, so that the armrest 623 can rotate around the rotating shaft of the armrest motor 622, so as to adjust the angle of the armrest 623 relative to the backrest side plate 611, and realize the purpose of adjusting the angle of the armrest 623 by using the armrest motor 622.

[0154] Understandably, the vehicle controller here can be an existing controller on the car, or a special controller separately arranged on the car seat. The special controller can communicate with the existing controller on the car, so as to determine the target working mode of the car seat according to the relevant information sent by the existing controller, and thus control the armrest of the car seat, for example, when the existing controller determines that the target working mode of the car seat is the adaptive mode, the target control instruction corresponding to the target working mode can be output to the special controller, so that the special controller responds to the target control instruction to perform adaptive angle adjustment of the armrest.
