SEAT CONTROL DEVICE AND METHOD

Abstract

A seat control device comprises a first drive part, a second drive part, and a controller. The device is configured to receive a user input regarding a walk-in mode via an input part, and based on the received user input, the device controls a sliding position of a seat to a walk-in position range corresponding to the walk-in mode using the first drive part, and to control a tilt angle of the seat to a walk-in angle range corresponding to the walk-in mode using the second drive part. Specifically, when the user input is received again via the input part, the device restores the tilt angle of the seat from the walk-in angle range to a non-walk-in angle range using the second drive part.

Description

TECHNICAL FIELD

[0001] The present disclosure relates to a seat control apparatus and a seat control method, and more particularly to a technology for controlling an operation mode of a specific seat. BACKGROUND

[0002] With technological advances, various components in a vehicle's interior can be interconnected. In particular, the seat control device can quickly and accurately provide various functions by performing cooperative control between the components for the convenience of a user.

[0003] For example, the vehicle may include multiple seats, and controlling a position (or operating mode) of a seat may require cooperative control of at least one of a seat's recline angle, lateral position, or tilt position, or any combination thereof. For example, technologies for improving a user's ride comfort by adjusting (e.g., setting a position of a particular seat to a walk-in mode) a position of a particular seat provided at a front side of a rear seat for driving when a user gets onto the rear seat of the particular seat.

[0004] However, since only a limited number of devices (e.g. a drive part) are available for changing the state of a set, it is difficult to create a seating state in which a user can get in and out of the vehicle as comfortably as possible.

[0005] For example, when a user inputs a walk-in mode instruction (e.g., a physical user input to a button) on a front seat (hereinafter: seat) to allow the user to easily enter the rear seat, a seat control device may perform control such that the sliding position and / or the tilt angle of the seat corresponds to the walk-in mode. After the seat control device controls the position of the seat to the walk-in mode in response to the user input, the user may manually move the sliding position of the seat to a non-walk-in angle range (e.g., a range on a rear side of a walk-in position range) corresponding to a non-walk-in angle range mode.After the situation, when a user input is received from the user again, the tilt angle is controlled into the non-walkable angle range corresponding to the non-walkable angle range mode by using a motor to control the tilt angle of the seat when the seat control device detects that a previous operation mode is the walkable mode, but the drive part (eg, a fixing part) for controlling the sliding position repeatedly performs the same operation (eg, unlocking) according to the user input, which can generate a gap between the tilt angle and the sliding position.

[0006] The statements in this section merely provide background information related to the present disclosure and do not constitute prior art. OVERVIEW

[0007] The present disclosure has been made to solve the above-mentioned problems encountered in the prior art while maintaining the advantages of the prior art.

[0009] An aspect of the present disclosure also provides a seat control device that can control a position of a seat among positions according to a walk-in mode or a non-walk-in angular range mode to a position opposite to a previous operation mode of the seat in response to a user input by using a first drive part and a second drive part comprising different types of devices.

[0022] According to one embodiment, the input part may comprise a first switch arranged in a region of a backrest of the seat and a second switch arranged in a region of a side cushion of the seat, and the instructions may be configured, when executed by the controller, to cause the seat control device to activate an operating mode control of the seat when an input to the first switch that exceeds a first time period is received, and to activate the operating mode control of the seat when an input to the second switch that exceeds a second time period that is shorter than a first time period is received.

[0023] According to one embodiment, the seat control device may further comprise a rear seat passenger detection sensor, wherein the instructions, when executed by the controller, may be configured to cause the seat control device to increase an input latency time requiring a period of user input into the input part when it is determined using the rear seat passenger detection sensor that a user is located in a rear seat of the seat.

[0038] To the extent that a component, device, element, or the like is described in the present disclosure as a component, device, or element that serves a purpose or performs an operation, function, or the like, the component, device, or element should be considered herein to be “configured” to serve that purpose or perform that operation or function.

[0039] Hereinafter, embodiments of the present disclosure will be described with reference to the Fig. 1 to 8 described in detail.

[0040] Fig. 1 is a block diagram showing the components of a seat control device according to an embodiment of the present disclosure.

[0041] According to one embodiment, a seat control device 100 may include at least one input part 110, a first drive part 120, a second drive part 130, a memory 140, a controller 150, a sensor part 160, or any combination thereof. Fig. The components of the seat control device 100 illustrated in Figure 1 are exemplary, and the embodiments of the present disclosure are not limited thereto. In another embodiment, the seat control device 100 may include additional components (e.g., at least one memory, an interface portion, a communication portion, a display portion, or any combination thereof) illustrated in Fig. 1 are not shown.

[0042] According to one embodiment, the input part 110 may comprise at least one switch.

[0043] In one embodiment, the input part 110 may comprise at least one switch provided in a region of the seat. The one region may, for example, comprise a region of the backrest of a seat and / or a region of a side cushion of the seat.

[0044] The input part 110 may, for example, comprise a first switch arranged in the one region of the backrest of the seat and a second switch arranged in the one region of the side cushion of the seat.

[0045] In one embodiment, an operating mode control of the seat may be activated when an input is received at the first switch that exceeds a first time period. In other words, only when the input is received at the switch that exceeds the first time period can the controller 150 detect that user input for changing the operating mode of the seat has been received.

[0046] In one embodiment, the seat's operating mode control may be activated when an input is received at the second switch that exceeds a second time period. In other words, only when the input is received at the second switch that exceeds the second time period can the controller 150 detect that the user input to change the seat's operating mode has been received. For example, the second time period may be shorter than the first time period. In other words, the time required to maintain the inputs may be shorter for the second switch than for the first switch.

[0047] In one embodiment, input part 110 may provide user input based on touch input provided by a user to controller 150. For example, if the touch input to input part 110 exceeds a certain period of time (or a period of time requiring sustained input), controller 150 may recognize (or identify) the corresponding touch input as user input.

[0048] In one embodiment, the input part 110 may change the specific time period described above according to control by the controller 150. For example, the controller 150 may increase the time period required to maintain input when a user is in a rear seat of a target seat to be controlled. In other words, when the user is in the rear seat, the controller 150 may increase the time period for which the input must be maintained, so that a touch input must be applied to the input part 110 by the user for a relatively long period of time to change the mode of the seat.

[0049] According to one embodiment, the first drive part 120 may comprise at least one drive device that controls the sliding position of the seat.

[0050] In one embodiment, the first drive part 120 may include a fixing part. For example, the first drive part 120 may fix (settle) a portion of the seat at a point of a non-walkable position range (also referred to as a non-walkable position range) corresponding to a non-walkable angle range mode by using the fixing part. This allows the sliding position of the seat to be fixed at the one point of the non-walkable position range.

[0051] In one embodiment, the first drive part 120 may include an actuator. The controller 150 may, for example, release (or unfasten) the fastening of the seat by the fastening part by activating (or operating) the actuator to control the sliding position of the seat into the walk-in position range corresponding to the walk-in mode. By doing so, the fastening of the seat at the one point described above can be released (or the seat and the fastening part can be released), and thus the seat can be moved forward. In other words, the seat can be moved to a point (e.g., a point included in the walk-in position range) on a front side of a current position of the seat by a repulsive force of a spring generated when the fastening part is released.

[0052] According to one embodiment, the second drive part 130 may comprise at least one motor that controls an inclination angle of the seat.

[0053] In one embodiment, the second drive part 130 may comprise a motor. The second drive part 130 may, for example, adjust the tilt angle of the seat to a specific angle. This allows the tilt angle of the seat to be changed to the walkable angle range, which corresponds to the walkable mode, or to the non-walkable angle range, which corresponds to the non-walkable angle range mode.

[0054] In one embodiment, the non-walkable angle range may include a region on the rear side of the walkable angle range when the seat is viewed from a side. In other words, the non-walkable angle range may be a region in which the backrest of the seat is located on a rear side of the walkable angle range.

[0055] In one embodiment, a seat may be classified as a semi-powered seat if its sliding position is mechanically locked and controlled by a mechanical lock rather than a motor, while the reclining angle is adjusted by a motor. The semi-powered seat may include an algorithm by which a part thereof is mechanically locked (or fixed) by the fixing member and fixed at a point (e.g., a point of the non-walkable position range), the actuator is actuated to release the fixing member when the mode needs to be changed to the walkable mode based on user input, and the seat is moved to a point (e.g., a point of the walkable range) on a front side by a repulsion force from the spring.

[0056] According to one embodiment, memory 140 may store instructions or data. For example, memory 140 may store one or more commands that, when executed by controller 150, cause seat control device 100 to perform various operations.

[0057] Memory 140 may be implemented, for example, by controller 150 and a chipset. Controller 150 may include at least one communications processor or a modem.

[0058] According to one embodiment, the controller 150 may be operatively connected to at least one of the following parts: the input part 110, the first drive part 120, the second drive part 130, the memory 140, the sensor part 160, or any combination thereof. For example, the controller 150 may control the operation of at least one of the following parts: the input part 110, the first drive part 120, the second drive part 130, the memory 140, the sensor part 160, or any combination thereof.

[0059] For example, the controller 150 may receive user input for the walk-in mode via the input part 110.

[0060] In one embodiment, the controller 150 may set a time period during which the input must be maintained for at least one switch included in the input part 110. The controller 150 may increase the time period during which the user input to the input part 110 must be maintained when it is detected that a user is in the rear seat of the target seat by using the rear seat passenger detection sensor included in the sensor part 160, and thus may detect that the user input is received only if the input to the input part 110 is maintained for a time period that exceeds the increased time period during which the input must be maintained.

[0061] In one embodiment, the user input may include a user input to the walkable mode (a change of the operating mode to the walkable mode or the non-walkable angle range mode).

[0062] For example, the controller 150 may control the position of the seat based on the received user input.

[0063] In one embodiment, the controller 150 may control the sliding position of the seat into the walk-in position range corresponding to the walk-in mode using the first drive part 120, and may control the tilt angle of the seat into the walk-in angle range corresponding to the walk-in mode using the second drive part 130. The controller 150 may release the fastening part by operating the actuator included in the first drive part 120, thereby moving the sliding position of the seat from an existing range to a forward range (e.g., the walk-in position range). In one embodiment, the controller 150 may control the tilt angle of the seat into the walk-in angle range including the forward range of the seat using the motor included in the second drive part 130.In this case, the seat is positioned at a location corresponding to the non-walkable angle range mode before the user input is received. In other words, if the seat is positioned at a location according to the walkable mode before the user input is received, the controller 150 can control the seat to the area corresponding to the non-walkable angle range mode by using the first drive part 120 and the second drive part 130.

[0064] In one embodiment, the controller 150 may restore the seat's inclination angle from the walkable angle range to the non-walkable angle range using the second drive part 130 when the user input is received again via the input part 110. In other words, the controller 150 may control the seat to the position according to the walkable mode in response to the received user input including the intention to switch to the initial walkable mode, and then may receive the user input again via the input part 110. In this case, the controller 150 may restore (or control) the seat's inclination angle to the non-walkable angle range using the second drive part 130 and may not provide a control command to the first drive part 120 (or may not operate the first drive part 120).

[0065] In one embodiment, the controller 150 may perform seat control according to the user input after identifying the previous operating mode of the seat. For example, the controller 150 may identify the previous operating mode of the seat through the sensor part 160 or based on a seat operation history stored in advance in the memory 140.

[0066] In one embodiment, the controller 150 may control the seat into the walk-in mode using the first drive part 120 and the second drive part 130 when the detected (identified) previous operating mode is in the non-walk-in angular range mode, which is opposite to the walk-in mode. A description of the embodiment of controlling the seat into the walk-in mode may be replaced by the description of the operation of the controller 150.

[0067] In one embodiment, when the identified previous operating mode is the walk-in mode, the controller 150 may control the sliding position of the seat into the non-walk-in position range corresponding to the non-walk-in angle range mode using the first drive part 120, and may control the tilt angle of the seat into the non-walk-in angle range corresponding to the non-walk-in angle range mode using the second drive part 130. Then, the operation using the first drive part 120 may include an operation of securing the seat such that a portion of the seat is secured to a point in the non-walk-in area using the fastening part included in the first drive part 120.

[0068] In one embodiment, the controller 150 may identify an operating state (e.g., at least one of the sliding positions, the tilt angle, or any combination thereof) of the seat using the seat position sensor. The controller 150 may control the operating mode of the seat through the first drive part 120 and the second drive part 130 to the walk-in mode or the non-walk-in angle range mode based on the identified operating state.

[0069] In one embodiment, the controller 150 may determine the tilt angle using at least one Hall sensor. The controller 150 may change (or set) and save the previous operating mode of the seat stored in the memory 140 based on the range containing the detected tilt angle. For example, if the identified tilt angle falls within the walk-in angle range, the controller 150 may change (or set) the previous operating mode of the seat stored in the memory 140 to the walk-in mode. As another example, if the identified tilt angle falls within the non-walk-in angle range, the controller 150 may change (or set) the previous operating mode of the seat stored in the memory 140 to the non-walk-in angle range mode.

[0070] In one embodiment, the controller 150 may receive a release control signal or a release control signal from the input part 110 that controls the seat into the walk-in mode or the non-walk-in angle range mode. In other words, when a user input is received from the user, the input part 110 may detect whether the corresponding user input is a request to place the seat into the non-walk-in angle range mode or the walk-in mode, and may then provide the detected control signal to the controller 150.

[0071] In one embodiment, after receiving a walk-in control signal instructing the seat to be controlled into the walk-in mode via the input part 110, the controller 150 may control the sliding position of the seat into the walk-in position range using the first drive part 120 and control the tilt angle of the seat into the walk-in angle range using the second drive part 130.

[0072] In one embodiment, upon receiving the non-walkable control signal instructing the seat to be controlled into the non-walkable angle range mode via the input part 110, the controller 150 may maintain the fastening state of the fastening part that fixes the sliding position of the seat using the first driving part 120 and control the inclination angle of the seat into the non-walkable angle range using the second driving part 130. In other words, after receiving the non-walkable control signal, the controller 150 may not provide a control signal to the first driving part 120 (or the actuator included in the first driving part 120) to maintain the fastening state of the non-walkable position range of the seat using the first driving part 120.

[0073] According to one embodiment, the sensor part 160 can collect information for controlling the seat using various types of sensors.

[0074] In one embodiment, the sensor part 160 may include at least one seat position sensor, at least one Hall sensor, the rear seat passenger detection sensor, or any combination thereof.

[0075] In one embodiment, the rear seat passenger detection sensor may detect whether a user is sitting in the rear seat (or a user corresponding to the rear seat is present) by sensing (e.g., by detecting weight) a rear seat mat located on the back of the seat to be controlled by the controller 150.

[0076] In one embodiment, the rear seat passenger detection sensor may detect whether the user is sitting in the rear seat (or a user corresponding to the rear seat is present) based on whether a fuse associated with the rear seat is set.

[0077] In one embodiment, the rear seat passenger detection sensor may detect whether the user is sitting in the rear seat (or a user corresponding to the rear seat is present) using a camera, a rear seat alert (ROA) system, or any combination thereof.

[0078] Below you can find the Fig. 2A, Fig. 2B and Fig. 2C refer to embodiments relating to at least one operational algorithm between various components of the seat control device 100 that may be implemented and / or the arrangement or presence of the components, or any combination thereof.

[0079] Fig. 2A is a block diagram showing the components of the seat control device according to an embodiment of the present disclosure.

[0080] Referring to Fig. 2A, the seat control device (e.g., the seat control device 100 of Fig. 1) according to one embodiment, an input part 211 (e.g., the input part 110 of Fig. 1), a controller 241 (e.g. the controller 150 of Fig. 1), a backrest adjustment drive part 221 (e.g. the second drive part 130 of Fig. 1) and / or a walk-in actuator 231 (e.g. the first drive part 120 of Fig. 1) include.

[0081] Referring to Fig. 2A, in one embodiment, the controller 241 directly identifies an operating mode for controlling the seat and provides a control signal (or operating instruction) to the seatback adjustment drive portion 221 and / or the walk-on actuator 231 when user input is received via the input portion 211.

[0082] For example, the controller 241 may directly identify an operating mode corresponding to a user input based on at least one of the information about operation of the seat provided by the sensor part (e.g., the sensor part 160 of Fig. 1), a history of seat operation stored in the memory (e.g. memory 140 of Fig. 1), or a combination of these. Then, the controller 241 may deliver a control signal generated based on the identified operating mode to the backrest adjustment drive part 221 and / or to the walk-in actuator 231. The controller 241 may receive information (e.g., a status message) about an operating state of the backrest adjustment drive part 221 and / or the walk-in actuator 231 and store at least a portion of the received information in memory.

[0083] Fig. 2B is a block diagram showing the components of the seat control device according to an embodiment of the present disclosure.

[0084] Referring to Fig. 2B, the seat control device (e.g., the seat control device 100 of Fig. 1) according to one embodiment, an input part 212 (e.g., the input part 110 of Fig. 1), a controller 242 (e.g., the controller 150 of Fig. 1), a sensor 252 (e.g. the sensor part 160 of Fig. 1), a drive part 222 for adjusting the backrest (e.g. the second drive part 130 of Fig. 1) and / or a walk-in actuator 232 (e.g. the first drive part 120 of Fig. 1) include.

[0085] As in Fig. 2B, in one embodiment, the controller 242 identifies an operating mode for controlling the seat based on information about an operating state of the seat obtained using the sensor 252 (e.g., the sensor portion 160 of Fig. 1) and provides a control signal (or operation / actuation instruction) to the backrest adjustment drive part 222 and / or the walk-on actuator 232 when a user input is received via the input part 212.

[0086] For example, shortly before receiving user input, the controller 242 may identify a seat operating mode using the sensor 252, including the seat position sensor, generate a control signal to control the seat in a mode opposite to the identified operating mode, and provide the generated control signal to the seatback adjustment drive part 222 and / or the walk-in actuator 232. The controller 242 may receive information (e.g., a status message) about an operating state from the seatback adjustment drive part 222 and / or the walk-in actuator 232 and may store at least a portion of the received information in memory.

[0087] Fig. 2C is a block diagram showing the components of the seat control device according to an embodiment of the present disclosure.

[0088] Referring to Fig. 2C, the seat control device (e.g., the seat control device 100 of Fig. 1) according to one embodiment, an input part 213 (e.g., the input part 110 of Fig. 1), a controller 243 (e.g. the controller 150 of Fig. 1), a backrest adjustment drive part 223 (e.g. the second drive part 130 of Fig. 1) and / or a walk-in actuator 233 (e.g. the first drive part 120 of Fig. 1) include.

[0089] As in Fig. 2C, in one embodiment, the controller 243 and / or the walk-in actuator 233 continuously counts the number of user inputs to the input part 213 and identifies an operating mode for controlling the seat based on the count result to control an operating mode of the seat when a user input is received via the input part 213.

[0090] For example, when a user input is received via the input part 213, the controller 241 may identify an operating mode corresponding to the user input and provide a control signal generated based on the identified operating mode to the backrest adjustment drive part 223.

[0091] In one embodiment, when a user input is received via the input part 213, the walk-in actuator 233 may continuously count the number of user inputs and request a control signal for an operation to the controller 243 if it is determined from the count result that an operation of the actuator is required. The walk-in actuator 233 may release the fastening part that has fixed the sliding position of the seat based on the control signal received from the controller 243 in response to the request. The controller 243 may receive information (e.g., a status message) about an operating state of the backrest adjustment drive part 223 and / or the walk-in actuator 233 and may store at least part of the received information in the memory.

[0092] Fig. 3 is a conceptual view of an operation (operation) of the seat control device according to an embodiment of the present disclosure.

[0093] According to one embodiment, the seat control device (e.g., the seat control device 100 of Fig. 1) Control a walk-in mode of the seat 305 to be controlled to the walk-in mode or the non-walk-in angle range mode.

[0094] For example, the seat control device may adjust the seat based on the received user input to the input part 310 (e.g., the input part 110 of Fig. 1) into walk-in mode (e.g. the one in Fig. 3). In this case, a previous operating mode of the seat 305, ie, an operating mode shortly before receiving the user input, may correspond to the inaccessible angle range mode.

[0095] In one embodiment, the input part 310 may include a first switch and a second switch arranged in a first area 312 in the backrest of the seat 305 and in a second area 314 in the side cushion of the seat 305, respectively.

[0096] In one embodiment, the time periods required for the first switch and the second switch to maintain inputs may be different. In other words, the seat controller may only enable the seat's operating mode control when an input is received at the first switch that exceeds a first time period, and may only enable the seat's operating mode control when an input is received at the second switch that exceeds a 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 time periods that require the first switch and the second switch to maintain inputs.

[0097] For example, since the seat is controlled using the walk-in mode, the user who is to sit on one of the rear seats 307 can be comfortably brought to the rear seat 307.

[0098] Fig. 4 is a conceptual view of an operation of the seat control device according to an embodiment of the present disclosure.

[0099] Referring to reference numeral 401, the seat control device (e.g., the seat control device 100 of Fig. 1) receive user input from the user via input portions 412 and 424, according to one embodiment.

[0100] For example, an input (e.g., a touch input) is sent to the first switch located in a first area 412 in the backrest of a seat 405 and / or to a second switch located in a second area 414 of the side bolster. If the input exceeds a time period required to maintain the input, the seat control device can detect that the user input has been received.

[0101] Referring to reference numeral 402, the seat control device according to one embodiment may control the inclination angle of the seat using the drive part (e.g., the second drive part 130 of Fig. 1) set.

[0102] For example, if the seat is in the non-walkable angle range mode before the user input is received, the seat control device may, in response to the received user input, control the tilt angle of the seat to a walkable angle range “a2” corresponding to the walkable mode.

[0103] For example, if the seat is in the walk-in mode before the user input is received, the seat control device may, in response to the received user input, control the tilt angle of the seat to a non-walk-in angle range “a1” corresponding to the non-walk-in angle range mode.

[0104] Fig. 5 is a flowchart of a seat control method according to an embodiment of the present disclosure.

[0105] According to one embodiment, the seat control device (e.g., the seat control device 100 of Fig. 1) the Fig. 5. For example, at least some of the components (e.g., the input part 110, the first drive part 120, the second drive part 130, the memory 140, the controller 150, and the sensor part 160 of Fig. 1) contained in the seat control device, be arranged to control the operations of Fig. 5 execute.

[0106] Subsequently, the operations from S510 to S545 may be executed sequentially, but do not necessarily have to be executed sequentially. For example, the order of the operations may be changed, and at least two operations may be executed in parallel. In addition, the contents corresponding to the above-mentioned Fig. 5, or the repeated content is briefly described or omitted.

[0107] According to one embodiment, the seat control device may detect whether a switching input has been received (S510).

[0108] For example, the seat control device may detect whether an input that exceeds a time period requiring maintenance of the input is made at a switch.

[0109] For example, if the input to the switch exceeding the required time to maintain the input is received (e.g., operation S510-Yes), the seat control device may perform operation S520.

[0110] For example, if an input to a switch that exceeds a time period required to maintain the input is not received (e.g., operation S510-No), the seat control device may repeatedly execute operation S510.

[0111] According to one embodiment, the seat control device may detect (determine) whether the previous operation mode of the seat is the non-walkable angle range mode (S520).

[0112] For example, the seat control device may detect whether the previous operating mode of the seat prior to receiving user input is the no-walk angle range mode by using at least one of the information sensed by the sensor part, the information stored in memory, or any combination thereof.

[0113] For example, if the previous operation mode of the seat is the inaccessible angle range mode (e.g., operation S520-Yes), the seat control device may perform operation S530.

[0114] For example, if the previous operation mode of the seat is not the non-walkable angle range mode or if the previous operation mode of the seat is the walkable mode (e.g., operation S520-No), the seat control device may perform operation S535.

[0115] According to one embodiment, the seat control device may control a tilt state up to a walkable angle by a tilt motor and activate the actuator (S530).

[0116] For example, the seat control device may change the operation mode of the seat to the walk-in mode by setting the tilt angle of the seat to the walk-in angle range corresponding to the walk-in mode by driving the tilt motor (e.g., the second drive part 130 of Fig. 1) and a sliding actuator (e.g. the first drive part 120 of Fig. 1) is activated to release the seat fastening and move the seat forward.

[0117] According to one embodiment, the seat control device can set the operating mode of the seat to the walk-in mode and store it in the memory.

[0118] For example, the seat control device may set the last operation mode of the seat to the walk-in mode and store the set operation history (operation history) in memory. The operation mode stored in operation S540 may be recognized as the previous operation mode when user input is received again later.

[0119] According to one embodiment, the seat control device may control the tilt state up to the unwalkable angle by the tilt motor and activate the slide actuator (S535).

[0120] For example, the seat control device may change the operation mode of the seat to the non-walkable angle range mode by setting the inclination angle of the seat to the non-walkable angle range corresponding to the non-walkable angle range mode by using the tilt motor and the slide actuator (e.g., the first drive part 120 of Fig. 1) deactivated to fix the seat at at least one point of the inaccessible position range.

[0121] According to one embodiment, the seat control device may set the operation mode of the seat to the non-walkable angle range mode and store it in the memory (S545).

[0122] For example, the seat control device may set the last operation mode of the seat to the non-walking angle range mode and store the set operation history (operation history) in memory. The operation mode stored in operation S545 may be recognized as the previous operation mode when user input is received again later.

[0123] Fig. 6 is a flowchart of a seat control method according to an embodiment of the present disclosure.

[0124] According to one embodiment, the seat control device (e.g., the seat control device 100 of Fig. 1) the Fig. 6. For example, the components (e.g., the input part 110, the first drive part 120, the second drive part 130, the memory 140, the controller 150, and the sensor part 160 of Fig. 1) contained in the seat control device, be arranged to control the operations of Fig. 6 to execute.

[0125] Subsequently, the operations from S610 to S645 may be executed sequentially, but they do not have to be executed sequentially. For example, the order of the operations can be changed, and at least two operations can be performed in parallel. In addition, the content corresponding to the above with respect to Fig. 6, or a repeated description of it is briefly described or omitted.

[0126] According to one embodiment, the seat control device may determine whether a switching input has been received (S610).

[0127] For example, the seat control device may detect whether an input has been received at the switch that exceeds a time period that requires the input to be maintained.

[0128] When the input to the switch that exceeds the time period for which the input must be maintained is received (e.g., operation S610-Yes), the seat control device may perform operation S620.

[0129] If the input to the switch exceeding the time period for which the input must be maintained is not received (e.g., operation S610-No), the seat control device may repeatedly execute operation S610.

[0130] According to one embodiment, the seat control device can use a sensor to determine whether a seat is located in the inaccessible area.

[0131] In one embodiment, the seat control device may use the seat position sensor to determine whether the tilt angle and / or the sliding position of the seat is within a range corresponding to the inaccessible angle range mode.

[0132] If it is determined that the position of the seat is in the inaccessible area (e.g., operation S620-Yes), the seat control device may perform operation S630.

[0133] If it is determined that the position of the seat is not in the non-walk-in area (or if it is determined that the position of the seat is in the walk-in area) (e.g., operation S620-No), the seat control device may perform operation S635.

[0134] According to one embodiment, the seat control device may control the tilt state up to the walkable angle by the tilt motor and activate the slide drive (S630).

[0135] In one embodiment, the seat control device may change the operating mode of the seat to the walk-in mode by setting the tilt angle of the seat to the walk-in angle range corresponding to the walk-in mode by controlling the tilt motor (e.g., the second drive part 130 of Fig. 1) and a sliding actuator (e.g. the first drive part 120 of Fig. 1) is activated to release the seat lock and move the seat forward.

[0136] According to one embodiment, the seat control device may set the operating mode of the seat to the walk-in mode and store it in the memory (S640).

[0137] In one embodiment, the seat control device may set the last operating mode of the seat to the walk-in mode and store the set operating history in memory. The operating mode stored in operation S640 may be recognized as the previous operating mode when user input is received again later.

[0138] According to one embodiment, the seat control device may control the tilt state up to the unwalkable angle by the tilt motor and activate the slide actuator (S635).

[0139] For example, the seat control device may change the operation mode of the seat to the non-walkable angle range mode by setting the inclination angle of the seat to the non-walkable angle range corresponding to the non-walkable angle range mode by using the tilt motor and the slide actuator (e.g., the first drive part 120 of Fig. 1) deactivated to fix the seat at at least one point of the inaccessible position range.

[0140] According to one embodiment, the seat control device may set the operating mode of the seat to the non-walkable angle range mode and store it in the memory (S645).

[0141] For example, the seat control device may set the last operation mode of the seat to the non-walking angle range mode and store the set operation history (operation history) in memory. The operation mode stored in operation S645 may be recognized as the previous operation mode when a user input is received again later.

[0142] Fig. 7 is a flowchart of a seat control method according to an embodiment of the present disclosure.

[0143] According to one embodiment, a seat control device (e.g., the seat control device 100 of Fig. 1) the Fig. 7. For example, the components (e.g., the input part 110, the first drive part 120, the second drive part 130, the memory 140, the controller 150, and the sensor part 160 of Fig. 1) contained in the seat control device, be arranged to control the operations of Fig. 7 to execute.

[0144] In the following, the operations from S710 to S740 can be executed sequentially, but they do not have to be executed sequentially. For example, the order of the operations can be changed, and at least two operations can be executed in parallel. In addition, the contents corresponding to the above-mentioned Fig. 7 described contents or a repeated description of them, are briefly described or omitted.

[0145] The following Fig. 7 under the premise that the operating mode of the seat before a user input is received is the inaccessible angle range mode.

[0146] According to one embodiment, the seat control device may receive a user input regarding the walk-in mode via the input part.

[0147] In one embodiment, the seat control device may detect that a user input is received when an input to the input part exceeds a time period that requires the input to be maintained. For example, the seat control device may increase the time period for which the input must be maintained for the input part if it detects that a user is in the rear seat who is positioned at the rear of the seat by using the rear seat passenger detection sensor.

[0148] According to one embodiment, the seat control device may control the sliding position of the seat by using the first driving part (S720).

[0149] For example, the seat control device may control the mode of the seat into the walk-in position range corresponding to the walk-in sliding walk-in mode of the seat by using the first drive part.

[0150] According to one embodiment, the seat control device can control the inclination angle of the seat by means of the second drive part.

[0151] For example, the seat control device can control the inclination angle of the seat with the aid of the second drive part within the range of the walkable angle corresponding to the walkable mode.

[0152] According to one embodiment, the seat control device may restore the tilt angle of the seat using the second drive part when a user input is received again via the input part.

[0153] In one embodiment, the seat control device may restore the tilt angle of the seat using the second drive part and not provide a control signal to the first drive part when a user input is received again after the seat exits the walk-in mode in operation S730. This allows the fastening part of the first drive part to be released. In other words, the sliding position of the seat may be controlled to be fixed at a point in the non-walk-in range by moving the seat into the non-walk-in range corresponding to the non-walk-in angle range mode and then maintaining a fixed (attached) state of the fastening part included in the first drive part.

[0158] The exemplary storage medium is connected to processor 1100, and processor 1100 can read information from and write information to the storage medium. In another method, the storage medium can be integrated with processor 1100. Processor 1100 and the storage medium can be located within an application-specific integrated circuit (ASIC). The ASIC can be housed in a user terminal. In another method, the processor and the storage medium can be housed as separate components in the user terminal.

[0159] The effects of the seat control apparatus and the seat control method according to the present disclosure are described as follows.

[0160] According to at least one of the embodiments of the present disclosure, the seat control device can prevent a discrepancy between the operating modes of the driving parts, including different types of driving devices, in a process of controlling an operating mode of the seat in response to a user input.

[0161] Moreover, according to at least one of the embodiments of the present disclosure, when controlling a position of the seat to a position corresponding to the walk-in mode based on a received user input (e.g., a switch input) related to a walk-in mode, manually moving a slide position to a non-walk-in position area (or an area on a back side of a walk-in position area) by a user, and then receiving a user input again, an operation of a drive part for controlling a slide position may not be performed in comprehensive consideration of an operation history of at least one sensor or the controller, a previous operation mode of the seat, and the like.

[0162] Furthermore, according to at least one of the embodiments of the present disclosure, when a walk-in operation is completed, a user manually moves the sliding position of the seat to the non-walk-in position range, and then a user input is received again, no operation signal may be transmitted to the attachment part for controlling the sliding position, whereby an adjustment performance of the sliding position and the tilt angle according to an operation mode of the seat can be maintained.
