Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of and priority to Korean Patent Application No. 10-2023-0093164 filed in the Korean Intellectual Property Office on July 18, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a seat control device and a seat control method, and more particularly, to a technology for controlling an operation mode of a specific seat. Background Art

[0004] With the development of technology, various components inside the vehicle can be connected to each other. In particular, the seat control device can quickly and accurately provide various functions for the convenience of users by performing cooperative control between components.

[0005] For example, a vehicle may include a plurality of seats, and in order to control the position (or operation mode) of the seats, it is necessary to coordinately control at least one of the tilt angle, side position or tilt position of the seats or any combination thereof. For example, a technology for improving the riding convenience of a user by adjusting the position of a specific seat located in front of the rear seat for riding (e.g., adjusting the position of the specific seat to a walk-in mode) when the user rides on the rear seat of the specific seat.

[0006] However, since the types of devices (eg, driving parts) provided for changing the seat state are limited, it is difficult to provide a seat state that allows the user to get on and off the vehicle with maximum convenience.

[0007] For example, when a user inputs a forward mode operation instruction (e.g., a physical input of a button by the user) to a front seat (hereinafter referred to as a seat) so that the user can easily sit on the rear seat, the seat control device may perform control so that the sliding position and / or the tilt angle of the seat corresponds to the forward mode. After the seat control device controls the position of the seat to the forward mode in response to the user input, the user may manually move the sliding position of the seat to a non-forward angle area position area (e.g., an area behind the forward position area) corresponding to the non-forward angle area mode. When a user input is received from the user again after this situation, when the seat control device recognizes that the previous operation mode is the forward mode, the tilt angle is controlled to the non-forward angle area corresponding to the non-forward angle area mode by using a motor for controlling the tilt angle of the seat, but the driving portion (e.g., a fixing portion) for controlling the sliding position repeatedly performs the same operation (e.g., unlocking) according to the user input, so that a gap may be generated between the tilt angle and the sliding position.

[0008] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. Summary of the invention

[0009] The present disclosure aims to solve the above-mentioned problems occurring in the prior art while maintaining the advantages achieved by the prior art unchanged.

[0011] One aspect of the present disclosure also provides a seat control device that can respond to user input by utilizing a first drive unit and a second drive unit comprising different types of devices to control the position of the seat to a position opposite to a previous operating mode of the seat according to a forward mode or a non-forward angle area mode.

[0012] An aspect of the present disclosure also provides a seat control device that fixes (or fastens) a portion of a seat to a point in a non-advanced position area by using a fixing portion included in a first driving portion.

[0050] When a component, device, element, etc. of the present disclosure is described as having a certain purpose or performing a certain operation, function, etc., the component, device or element should be considered as being “configured to” satisfy the purpose or perform the operation or function.

[0051] In the following, reference will be made to Figures 1 to 8Embodiments of the present disclosure are described in detail.

[0052] Figure 1 is a block diagram illustrating components of a seat control device according to an embodiment of the present disclosure.

[0053] According to an embodiment, the seat control device 100 may include at least one of an input portion 110 , a first driving portion 120 , a second driving portion 130 , a memory 140 , a controller 150 , a sensor portion 160 , or any combination thereof. Figure 1 The components of the seat control device 100 shown are exemplary, and the embodiments of the present disclosure are not limited thereto. In another embodiment, the seat control device 100 may further include Figure 1 Components not shown in the figure (for example, at least one of a memory, an interface portion, a communication portion, a display portion, or any combination thereof).

[0054] According to an embodiment, the input part 110 may include at least one switch.

[0055] In an embodiment, the input unit 110 may include at least one switch, and the at least one switch is disposed in an area of ​​the seat. For example, the area may include an area of ​​the seat back and / or an area of ​​the seat side cushion.

[0056] For example, the input portion 110 may include a first switch and a second switch, the first switch being disposed in one region of the seat back and the second switch being disposed in one region of the seat side cushion.

[0057] In an embodiment, when the input of the first switch exceeding the first time period is received, the operation mode control of the seat can be started. In other words, only when the input of the switch exceeding the first time period is received, the controller 150 can recognize that the user input for changing the operation mode of the seat is received.

[0058] In an embodiment, when the input of the second switch is input for more than the second time period, the operation mode control of the seat may be started. In other words, only when the input of the second switch is received for more than the second time period, the controller 150 may recognize that the user input for changing the operation mode of the seat is received. The second time period may be shorter than the first time period, for example. In other words, the input of the second switch may be required to maintain a shorter time period than the input of the first switch.

[0059] In an embodiment, the input unit 110 may transmit a user input based on a touch input transmitted from the user to the controller 150. For example, when a touch input input to the input unit 110 exceeds a certain period of time (or an input maintenance required period of time), the controller 150 may recognize (or discern) the corresponding touch input as a user input.

[0060] In an embodiment, the input unit 110 may change the above-mentioned specific time period according to the control of the controller 150. For example, when the user appears on the rear seat of the target seat to be controlled, the controller 150 may increase the input maintenance requirement time period. In other words, when the user appears on the rear seat, the controller 150 may increase the input maintenance requirement time period so that the user must apply the touch input to the input unit 110 within a relatively long period of time to change the mode of the seat.

[0061] According to an embodiment, the first driving portion 120 may include at least one driving device that controls a sliding position of the seat.

[0062] In an embodiment, the first drive unit 120 may include a fixing portion. For example, the first drive unit 120 may fix a portion of the seat to a point in a non-advancing position region (also referred to as a non-advancing position region) corresponding to the non-advancing angle region mode by using the fixing portion. In this way, the sliding position of the seat may be fixed to a point in the non-advancing position region.

[0063] In an embodiment, the first drive unit 120 may include an actuator. For example, the controller 150 may control the sliding position of the seat to the forward position area corresponding to the forward mode by starting (or operating) the actuator, thereby releasing (or loosening) the fixation of the seat by the fixing portion. In this way, the fixation of the seat to the above-mentioned one point can be released (or the fixation of the seat and the fixing portion can be released), so that the seat can move forward. In other words, the seat can be moved to a point on the front side of the current position of the seat (for example, a point included in the forward position area) by the repulsive force of the spring generated when the fixing portion is released.

[0064] According to an embodiment, the second driving portion 130 may include at least one motor to control a tilt angle of the seat.

[0065] In an embodiment, the second drive unit 130 may include a motor. For example, the second drive unit 130 may control the tilt angle of the seat to a specific angle. In this way, the tilt angle of the seat may be changed to a forward angle region corresponding to the forward mode or a non-forward angle region corresponding to the non-forward angle region mode.

[0066] In an embodiment, when the seat is viewed from the side, the non-advance angle region may include an area behind the advance angle region. In other words, the non-advance angle region may be an area where the seat back exists behind the advance angle region.

[0067] In an embodiment, when the sliding position of the seat is mechanically locked and controlled by a mechanical lock instead of a motor while the tilt angle is adjusted by a motor, the seat can be classified as a semi-electric seat. The semi-electric seat may include an algorithm by which a portion of the seat is mechanically locked (or fastened) by a fixing portion and fixed to a point (e.g., a point in the non-advance position area), and when the mode must be changed to the advance mode based on a user input, an actuator is operated to release the fixing portion and move the seat to a point on the front side (e.g., a point in the advance position area) by the repulsive force of a spring.

[0068] According to an embodiment, the memory 140 may store instructions or data. For example, the memory 140 may store one or more instructions that, when executed by the controller 150 , cause the seat control device 100 to perform various operations.

[0069] For example, the memory 140 may be implemented by the controller 150 and a chipset. The controller 150 may include at least one of a communication processor or a modem.

[0070] According to an embodiment, the controller 150 may be operably connected to at least one of the input unit 110, the first drive unit 120, the second drive unit 130, the memory 140, the sensor unit 160, or any combination thereof. For example, the controller 150 may control the operation of at least one of the input unit 110, the first drive unit 120, the second drive unit 130, the memory 140, the sensor unit 160, or any combination thereof.

[0071] For example, the controller 150 may receive a user input regarding the forward mode through the input portion 110 .

[0072] In an embodiment, the controller 150 may adjust an input maintenance required time period of at least one switch included in the input portion 110. When a user is recognized to be present on a seat behind the target seat by using a rear seat passenger detection sensor included in the sensor portion 160, the controller 150 may increase an input maintenance required time period of a user input to the input portion 110, and thus, only when the time period for which the input to the input portion 110 is maintained exceeds the increased input maintenance required time period, it may be recognized that the user input is received.

[0073] In an embodiment, the user input may include a user input regarding the advancing mode (the operation mode is changed to the advancing mode or the non-advancing angle zone mode).

[0074] For example, the controller 150 may control the position of the seat based on received user input.

[0075] In an embodiment, the controller 150 can control the sliding position of the seat to the forward position area corresponding to the forward mode by using the first drive unit 120, and can control the tilt angle of the seat to the forward angle area corresponding to the forward mode by using the second drive unit 130. The controller 150 can loosen the fixing portion by operating the actuator included in the first drive unit 120, thereby moving the sliding position of the seat from the current area to the front area (e.g., the forward position area). In one embodiment, the controller 150 can control the tilt angle of the seat to the forward angle area including the front area of ​​the seat by using the motor included in the second drive unit 130. In this case, before receiving the user input, the seat is positioned at a position according to the non-forward angle area mode. In other words, when the seat is positioned at a position according to the forward mode before receiving the user input, the controller 150 can control the seat to the area corresponding to the non-forward angle area mode by using the first drive unit 120 and the second drive unit 130.

[0076] In an embodiment, when the user input is received again through the input unit 110, the controller 150 may restore the reclining angle of the seat from the advancing angle region to the non-advancing angle region by using the second drive unit 130. In other words, the controller 150 may control the seat to a position according to the advancing mode in response to the received user input including the intention to change to the initial advancing mode, and then may receive the user input again through the input unit 110. In this case, the controller 150 may restore (or control) the reclining angle of the seat to the non-advancing angle region by using the second drive unit 130, and may not transmit the control command to the first drive unit 120 (or may not operate the first drive unit 120).

[0077] In an embodiment, the controller 150 may perform seat control corresponding to the user input after identifying the previous operation mode of the seat. For example, the controller 150 may identify the previous operation mode of the seat through the sensor unit 160 or based on the operation history of the seat pre-stored in the memory 140.

[0078] In an embodiment, when the recognized previous operation mode is in a non-advance angle area mode opposite to the advance mode, the controller 150 may control the seat to the advance mode by utilizing the first drive unit 120 and the second drive unit 130. The description of the embodiment of controlling the seat to the advance mode may be replaced by a description of the operation of the controller 150.

[0079] In an embodiment, when the recognized previous operation mode is the forward mode, the controller 150 may control the sliding position of the seat to the non-forward position region corresponding to the non-forward angle region mode by using the first drive unit 120, and may control the tilt angle of the seat to the non-forward angle region corresponding to the non-forward angle region mode by using the second drive unit 130. Then, the operation using the first drive unit 120 may include an operation of fastening the seat so that a part of the seat is fixed to one point of the non-forward position region by using a fixing portion included in the first drive unit 120.

[0080] In one embodiment, the controller 150 can identify the operating state of the seat (e.g., at least one of the sliding position, tilt angle, or any combination thereof) by using a seat position sensor. The controller 150 can control the operating mode of the seat to the forward motion mode or the non-forward angle zone mode through the first drive unit 120 and the second drive unit 130 based on the identified operating state.

[0081] In an embodiment, the controller 150 may identify the tilt angle by utilizing at least one Hall sensor. The controller 150 may change (or set) and store the previous operation mode of the seat stored in the memory 140 based on the area including the identified tilt angle. As an example, when the identified tilt angle is included in the forward angle area, the controller 150 may change (or set) the previous operation mode of the seat stored in the memory 140 to the forward mode. As another example, when the identified tilt angle is included in the non-advancing angle area, the controller 150 may change (or set) the previous operation mode of the seat stored in the memory 140 to the non-advancing angle area mode.

[0082] In an embodiment, the controller 150 may receive a forward control signal or a non-forward control signal for controlling the seat to the forward mode or the non-forward angle zone mode from the input unit 110. In other words, when receiving a user input from the user, the input unit 110 may identify whether the corresponding user input is a request for changing the seat to the non-forward angle zone mode or the forward mode, and then may transmit the identified control signal to the controller 150.

[0083] In an embodiment, when a forward control signal indicating that the seat is controlled to a forward mode is received through the input unit 110, the controller 150 can control the sliding position of the seat to a forward position area by utilizing the first drive unit 120, and can control the tilt angle of the seat to a forward angle area by utilizing the second drive unit 130.

[0084] In the embodiment, upon receiving a non-advance control signal indicating that the seat is controlled to the non-advance angle region mode through the input portion 110, the controller 150 may maintain the fastened state of the sliding position of the fixed seat of the fixed portion by using the first drive portion 120, and may control the tilt angle of the seat to the non-advance angle region by using the second drive portion 130. In other words, upon receiving the non-advance control signal, the controller 150 may not transmit a control signal to the first drive portion 120 (or an actuator included in the first drive portion 120) to maintain the fixed state of the non-advance position region of the seat by using the first drive portion 120.

[0085] According to an embodiment, the sensor part 160 may acquire information for controlling the seat by using various types of sensors.

[0086] In an embodiment, the sensor portion 160 may include at least one of a seat position sensor, at least one Hall sensor, a rear seat passenger detection sensor, or any combination thereof.

[0087] In an embodiment, the rear seat passenger detection sensor can identify whether a user is sitting on the rear seat (or whether there is a user corresponding to the rear seat) by detecting the seat cushion of the rear seat (e.g., detecting its weight) to be controlled by the controller 150.

[0088] In an embodiment, the rear seat passenger detection sensor may recognize whether a user is sitting on the rear seat (or whether a user corresponding to the rear seat exists) based on whether a safety device corresponding to the rear seat is fastened.

[0089] In an embodiment, the rear seat passenger detection sensor can identify whether a user is sitting in the rear seat (or whether there is a user corresponding to the rear seat) based on at least one of a camera, a rear seat occupant alert (ROA) system, or any combination thereof.

[0090] In the following, Figure 2A , Figure 2B and Figure 2C Embodiments may relate to at least one of an operation algorithm between various components of the seat control device 100 that can be implemented and / or an arrangement or existence of components, or any combination thereof.

[0091] Figure 2A is a block diagram illustrating components of a seat control device according to an embodiment of the present disclosure.

[0092] Reference Figure 2A According to an embodiment, a seat control device (eg, Figure 1 The seat control device 100 may include an input unit 211 (eg, Figure 1 Input unit 110), controller 241 (for example, Figure 1 Controller 150), backrest adjustment drive unit 221 (for example, Figure 1 The second driving unit 130) and / or the forward actuator 231 (for example, Figure 1 The first driving unit 120).

[0093] Reference Figure 2A As an embodiment, when receiving user input through the input unit 211, the controller 241 directly identifies the operation mode for controlling the seat and transmits the control signal (or operation instruction) to the backrest adjustment drive unit 221 and / or the forward actuator 231.

[0094] For example, the controller 241 may be based on the sensor portion (e.g., Figure 1 The information about the operation of the seat acquired by the sensor unit 160, the memory (for example, Figure 1 The controller 241 may directly identify the operation mode corresponding to the user input based on at least one of the operation history of the seat stored in the memory 140 or any combination thereof. The controller 241 may then transmit the control signal generated based on the identified operation mode to the backrest adjustment drive 221 and / or the forward actuator 231. The controller 241 may receive information (e.g., status notification) about the operation status of the backrest adjustment drive 221 and / or the forward actuator 231, and may store at least a portion of the received information in the memory.

[0095] Figure 2B is a block diagram illustrating components of a seat control device according to an embodiment of the present disclosure.

[0096] Reference Figure 2B According to an embodiment, a seat control device (eg, Figure 1 The seat control device 100 may include an input unit 212 (eg, Figure 1 110), the controller 242 (e.g., Figure 1 Controller 150), sensor 252 (e.g., Figure 1 sensor unit 160), a backrest adjustment drive unit 222 (eg, Figure 1 The second drive unit 130 of FIG. 1 ), and / or the forward actuator 232 (eg, Figure 1 The first driving unit 120).

[0097] like Figure 2BAs shown in , as an embodiment, the controller 242 identifies an operating mode for controlling the seat based on information about the operating status of the seat obtained by utilizing a sensor 252 (e.g., the sensor portion 160 of the seat), and when a user input is received through the input portion 212, a control signal (or operating instruction) is transmitted to the backrest adjustment drive portion 222 and / or the forward actuator 232.

[0098] For example, the controller 242 may identify the seat operation mode by using the sensor 252 including the seat position sensor shortly before receiving the user input, may generate a signal for controlling the seat in a mode opposite to the identified operation mode, and may transmit the generated control signal to the backrest adjustment drive 222 and / or the forward actuator 232. The controller 242 may receive information about the operation status (e.g., status notification) from the backrest adjustment drive 222 and / or the forward actuator 232, and may store at least a portion of the received information in a memory.

[0099] Figure 2C is a block diagram illustrating components of a seat control device according to an embodiment of the present disclosure.

[0100] Reference Figure 2C According to an embodiment, a seat control device (eg, Figure 1 The seat control device 100 may include an input unit 213 (eg, Figure 1 Input unit 110), controller 243 (for example, Figure 1 Controller 150), backrest adjustment drive unit 223 (for example, Figure 1 The second driving unit 130) and / or the forward actuator 233 (for example, Figure 1 The first driving unit 120).

[0101] like Figure 2C As shown, as an embodiment, the controller 243 and / or the forward actuator 233 continuously counts the number of user inputs to the input unit 213, and when the user input is received through the input unit 213, identifies the operating mode for controlling the seat based on the counting result to control the operating mode of the seat.

[0102] For example, when receiving a user input through the input portion 213 , the controller 241 may identify an operation mode corresponding to the user input, and may transmit a control signal generated based on the identified operation mode to the backrest adjustment driving portion 223 .

[0103] In an embodiment, when a user input is received through the input portion 213, the forward actuator 233 may continuously count the number of user inputs, and based on the counting result, when it is determined that the operation of the actuator is necessary, a request for a control signal for operation may be issued to the controller 243. In response to the request, the forward actuator 233 may release the fixing portion that has fixed the sliding position of the seat based on the control signal received from the controller 243. The controller 243 may receive information about the operating status (e.g., status notification) from the backrest adjustment drive portion 223 and / or the forward actuator 233, and may store at least a portion of the received information in a memory.

[0104] Figure 3 is a conceptual diagram of the operation of the seat control device according to the embodiment of the present disclosure.

[0105] According to an embodiment, a seat control device (eg, Figure 1 The seat control device 100) can control the operation mode of the seat 305 to be controlled to the forward mode or the non-forward angle area mode.

[0106] For example, the seat control device may receive an input 310 (eg, Figure 1 The seat is controlled to the forward mode (eg, Figure 3 In this case, the previous operating mode of the seat 305, ie, the operating mode shortly before receiving the user input, may correspond to the non-advance angle zone mode.

[0107] In an embodiment, the input portion 310 may include a first switch and a second switch, which are respectively disposed in a first area 312 included in a backrest of the seat 305 and in a second area 314 included in a side cushion of the seat 305 .

[0108] In an embodiment, the input maintenance requirement time periods of the first switch and the second switch may be different. In other words, the seat control device may start the operation mode control of the seat only when the input of the first switch is received for more than the first time period, and may start the operation mode control of the seat only when the input of the second switch is received for more than the second time period. The second time period is shorter than the first time period. The first time period and the second time period may be the input maintenance requirement time periods for the first switch and the second switch.

[0109] For example, since the seat is controlled based on the forward mode, a user who is to sit on the rear seat 307 can conveniently move to the rear seat 307 .

[0110] Figure 4 is a conceptual diagram of the operation of the seat control device according to the embodiment of the present disclosure.

[0111] Referring to reference numeral 401, according to an embodiment, a seat control device (eg, Figure 1 The seat control device 100 ) can receive user input from the user through input parts 412 and 414 .

[0112] For example, an input (e.g., a touch input) is sent to a first switch provided in a first area 412 included in a backrest of the seat 405 and / or a second switch provided in a second area 414 of a side cushion. When the input exceeds the input maintenance requirement time period, the seat control device may recognize that the user input is received.

[0113] Referring to reference numeral 402, according to an embodiment, the seat control device may be configured to control the seat by utilizing a driving unit (eg, Figure 1 The second driving unit 130) is used to adjust the tilt angle of the seat.

[0114] For example, when the seat is in the non-advance angle zone mode before receiving the user input, the seat control device may control the reclining angle of the seat to the advance angle zone "a2" corresponding to the advance mode in response to the received user input.

[0115] For example, when the seat is in the advancing mode before receiving the user input, the seat control device may control the reclining angle of the seat to the non-advancing angle region “ a1 ” corresponding to the non-advancing angle region mode in response to the received user input.

[0121] For example, when an input of the switch exceeding the input maintenance required time period is received (eg, operation S510 -YES), the seat control device may perform operation S520 .

[0122] For example, when the input of the switch exceeding the input maintenance required time period is not received (eg, operation S510 —No), the seat control device may repeatedly perform operation S510 .

[0123] According to an embodiment, the seat control device may identify whether a previous operation mode of the seat is a non-advance angle zone mode ( S520 ).

[0124] For example, the seat control device may identify whether a previous operation mode of the seat before receiving a user input is the non-advance angle zone mode by utilizing at least one of information acquired through the sensor portion, information stored in the memory, or any combination thereof.

[0125] For example, when the previous operation mode of the seat is the non-advance angle zone mode (eg, operation S520-YES), the seat control device may perform operation S530.

[0126] For example, when the previous operation mode of the seat is not the non-advance angle zone mode or when the previous operation mode of the seat is the advance mode (eg, operation S520-No), the seat control device may perform operation S535.

[0127] According to an embodiment, the seat control device may control the reclining state to a forward angle through a reclining motor and may activate an actuator ( S530 ).

[0129] According to an embodiment, the seat control device may set the operation mode of the seat to the forward mode and store it in the memory.

[0130] For example, the seat control device may set the most recent operation mode of the seat to the forward mode and may store the setting operation history in the memory. When the user input is received again later, the operation mode stored in operation S540 may be recognized as the previous operation mode.

[0131] According to an embodiment, the seat control device may control the tilt state to a non-advance angle through the tilt motor, and may deactivate the slide actuator ( S535 ).

[0132] For example, the seat control device may adjust the reclining angle of the seat to the non-advancing angle region corresponding to the non-advancing angle region mode by using the reclining motor and deactivating the slide actuator (e.g., Figure 1 The first driving portion 120) is used to fix the seat to at least one point in the non-advancing position area to change the operation mode of the seat to the non-advancing angle area mode.

[0146] According to an embodiment, the seat control device may control the tilt state to the forward angle through the tilt motor and may activate the slide actuator ( S630 ).

[0147] In one embodiment, the seat control device can be configured to tilt by utilizing a tilt motor (e.g., Figure 1 The second driving unit 130 of the seat adjusts the reclining angle of the seat to the forward angle region corresponding to the forward mode, and starts the sliding actuator (eg Figure 1 The first driving unit 120) is used to release the seat and move the seat forward to change the operation mode of the seat to the forward mode.

[0150] According to an embodiment, the seat control device may control the tilt state to a non-advance angle through the tilt motor, and may deactivate the slide actuator ( S635 ).
