[0016] The first sheet controller is characterized by being configured to determine that the first connector and the second connector are conductively connected when it detects a ground signal when the first-1 detection pin and the first-2 detection pin of the first connector make conductive contact with the second detection pin of the second connector.

[0017] The second seat controller is characterized by being configured to transmit a power supply and drive control signal to the swivel motor to rotate the electric child seat toward the door when receiving a door opening signal from the door switch and a vehicle stop signal from the vehicle speed sensor at the same time.

[0018] The second seat controller is characterized by being configured to transmit a power supply and drive control signal to the swivel motor to rotate the electric child seat toward the front of the vehicle when receiving a door closing signal from the door switch and simultaneously receiving a vehicle speed detection signal of 1 km / h or more from the vehicle speed sensor.

[0019] To achieve the above objective, another embodiment of the present invention provides a method for controlling an electric child seat for an automobile, comprising: a step of supplying power to a seat controller; a step of determining whether there is a request for operation of an electric component of a vehicle seat or an electric child seat in the seat controller; a step of determining whether there is a connection between a first connector mounted on the vehicle seat and a second connector mounted on the electric child seat in the seat controller if there is a request for operation; a step of applying a power supply and drive control signal to an electric component of the electric child seat in the seat controller if it is determined that the first connector and the second connector are connected; and a step of applying a power supply and drive control signal to an electric component of the vehicle seat in the seat controller if it is determined that the first connector and the second connector are not connected.

Specific details for implementing the invention

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0034] Figures 1 and 2 attached are configuration diagrams illustrating a control system for an electric child seat for an automobile according to the present invention, and Figure 3 is a perspective view illustrating an example of an electric child seat for an automobile and a vehicle seat according to the present invention.

[0035] As shown in FIGS. 1 and 2, the vehicle seat (100) includes a seat controller (10) for power supply and drive control for various electrical components mounted on the vehicle seat.

[0036] The vehicle seat (100) is equipped with an electrical component, a first heater mat (110) for heating and a first ventilation blower (120) for cooling, and a seat position adjustment motor (130) including a reclining adjustment motor (131) for adjusting the angle of the seat back, a seat sliding motor (132) for adjusting the front and rear position of the seat, and a seat cushion tilting motor (133) for tilting the seat cushion.

[0037] As shown in FIG. 3, an electric child seat (200) can be seated on the vehicle seat (100) above for the safe seating of an infant.

[0038] Unlike conventional manual type child seats, the above electric child seat (200) may be equipped with a second heater mat (210) for heating and a second ventilation blower (220) for cooling, and may also be equipped with a reclining adjustment motor (231) for adjusting the angle of the child seat and a swivel motor (232) for swivel operation of the child seat.

[0039] According to the present invention, the seat controller (10) is configured to provide power supply and drive control for the first heater mat (110), the first ventilation blower (120), the seat position adjustment motor (130) including the reclining adjustment motor (131) and the seat sliding motor (132), and is also configured to provide power supply and drive control for the second heater mat (210), the second ventilation blower (220), the reclining adjustment motor (231) and the swivel motor (232).

[0040] Preferably, the seat controller (10) may be composed of a first seat controller (11) and a second seat controller (12) for smooth control of a plurality of electrical components.

[0041] To this end, the first seat controller (11) may be configured to transmit power supply and drive control signals to the second heater mat (210) and second ventilation blower (220) mounted on the electric child seat (200) in addition to the first heater mat (110) and first ventilation blower (120) mounted on the vehicle seat (100), and to determine whether a connection is made between the first connector (140) and the second connector (240) described later.

[0042] Additionally, the second seat controller (12) may be configured to transmit power supply and drive control signals to a reclining adjustment motor (231) and a swivel motor (232) mounted on the electric child seat (200), in addition to a seat position adjustment motor (130) mounted on the vehicle seat (100).

[0043] A plurality of operation request units (20) are connected to the input portion of the seat controller (10), and the plurality of operation request units (20) include a vehicle switch (21) that can be directly operated by the driver, a CAN bus (22) that transmits voice command signals and vehicle information detection signals (e.g., door switch open and close signals, vehicle speed detection signals, etc.) to the seat controller (10), and a smart device (23) that is wirelessly connected to the seat controller (10).

[0044] For reference, the above CAN bus refers to a CAN (Controller Area Network) communication line that allows sensor signals to be transmitted to a controller without a host computer within the vehicle.

[0045] Accordingly, when an operation request signal of any one of the operation signal of the vehicle switch (21), the vehicle information detection signal of the CAN bus (22), and the operation signal of the smart device (23) is input to the seat controller (10), power supply and drive control can be performed for at least one of the first heater mat (110), the first ventilation blower (120), the seat position adjustment motor (130) including the reclining adjustment motor (131), the seat sliding motor (132), and the seat cushion tilting motor (133), the second heater mat (210), the second ventilation blower (220), the reclining adjustment motor (231), and the swivel motor (232).

[0046] Meanwhile, the vehicle seat (100) is equipped with a first connector (140) connected to the output of the seat controller (10) as shown in FIGS. 3 and 4, and the electric child seat (200) is equipped with a second connector (240) connected to the input of the electric components of the electric child seat as shown in FIGS. 3 and 4.

[0047] Preferably, the first connector (140) can be protected by a cover member (33) rotatably mounted on the vehicle seat (100) so as not to be exposed externally.

[0048] Accordingly, when an electric child seat (200) is placed on the vehicle seat (100) and, as shown in FIG. 5, the second connector (240) is passed through the cover member (33) and inserted and connected to the first connector (140) so as to be conductive, the power supply and drive control signals of the seat controller (10) can be transmitted through the first connector (140) and the second connector (240) to the electric components of the electric child seat, such as the second heater mat (210), the second ventilation blower (220), the reclining adjustment motor (231), and the swivel motor (232).

[0049] For example, if the second connector (240) of the electric child seat (200) is electrically inserted and connected to the first connector (140) of the vehicle seat, the power supply and drive control signals of the seat controller (10) can be transmitted to the second heater mat (210) and the second ventilation blower (220) of the electric child seat (200) shown in FIG. 6.

[0050] Meanwhile, the seat controller (10) is configured to determine whether the first connector (140) and the second connector (240) are connected so that power supply and drive control signals can be transmitted to the electrical components of the electric child seat only when the connection between the first connector (140) and the second connector (240) is securely established.

[0051] To this end, the first connector (140) is provided with a first-1 detection pin (31) connected to the first sheet controller (11) via a conductive line (11-1) as shown in FIG. 1, and a first-2 detection pin (32) connected to the first sheet controller (11) via a ground line (11-2), and the second connector (240) may be provided with a second detection pin (42) that is in conductive contact with the first-1 detection pin (31) and the first-2 detection pin (32) as shown in FIG. 1.

[0052] Accordingly, the first sheet controller (11) can determine that the first connector (140) and the second connector (240) are securely connected in a conductive manner when the first-1 detection pin (31) and the first-2 detection pin (32) of the first connector (140) make conductive contact with the second detection pin (42) of the second connector (240) and detect a ground signal from the ground line (11-2).

[0053] On the other hand, if the ground signal is not detected when the first-1 detection pin (31) and the first-2 detection pin (32) of the first connector (140) are conductively contacting the second detection pin (42) of the second connector (240) in the first seat controller (11), it is determined that the first connector (140) and the second connector (240) are not connected.

[0054] Meanwhile, the second seat controller (12) is configured to transmit a power supply and drive control signal to the swivel motor (232) of the electric child seat (200) to rotate the electric child seat toward the door when it receives a door opening signal from the door switch (24) from the CAN bus (22) and simultaneously receives a vehicle stop signal from the vehicle speed sensor (25).

[0055] Accordingly, the electric child seat (200) can be rotated in the door opening direction (boarding / alighting direction) as shown in FIG. 7 by driving the swivel motor (232), thereby providing convenience for the infant to sit or alight from the electric child seat.

[0056] On the other hand, the second seat controller (12) is configured to receive a door closing signal from the door switch (24) from the CAN bus (22) and, at the same time, receive a vehicle speed detection signal exceeding 0 km / h from the vehicle speed sensor (24), to transmit a power supply and drive control signal to the swivel motor (232) to rotate the electric child seat (200) toward the front of the vehicle in order to ensure a safe seating state for the infant.

[0057] Meanwhile, the electric child seat (200) may also have a separate controller built in for individual operation control of electrical components including a second heater mat (210), a second ventilation blower (220), a reclining adjustment motor (231), a swivel motor (232), etc.

[0058] Here, various embodiments of the control example of the electric child seat of the present invention based on the above-described configuration are as follows.

[0059] Figure 8 attached is a flowchart illustrating an example of a control method for an electric child seat for an automobile according to the present invention.

[0060] First, battery power is supplied to the seat controller (10) for control activation according to the vehicle ignition (S101).

[0061] Next, the seat controller (10) determines whether there is an operation request from the operation request unit (20) for an electrical component of the vehicle seat (100) or an electrical component of the electric child seat (200).

[0062] For example, the seat controller (10) may determine whether there is a request to operate the second heater mat (210) for heating among the electric components of the electric child seat (S102), or whether there is a request to operate the second ventilation blower (220) for cooling among the electric components of the electric child seat (S107).

[0063] If, as a result of the judgment in step S102 above, there is a request for operation of the second heater mat (210), the seat controller (10) determines whether to connect the first connector (140) mounted on the vehicle seat (100) and the second connector (240) mounted on the electric child seat (200) (S103), and likewise, if, as a result of the judgment in step S107 above, there is a request for operation of the second ventilation blower (220), the first connector (140) and the second connector (240) determine whether to connect (S108).

[0064] If there is an operation request for an electrical component of the vehicle seat (100) from the operation request unit (20), the seat controller (10) applies power supply and drive control signals to the electrical component of the vehicle seat.

[0065] At this time, when the first seat controller (11) among the seat controllers (10) as described above detects a ground signal from the ground line (11-2) when the first-1 detection pin (31) and the first-2 detection pin (32) of the first connector (140) are conductively in contact with the second detection pin (42) of the second connector (240), the first connector (140) and the second connector (240) can be determined to be conductively connected.

[0066] On the other hand, if the ground signal is not detected when the first-1 detection pin (31) and the first-2 detection pin (32) of the first connector (140) are conductively contacting the second detection pin (42) of the second connector (240) in the first seat controller (11), it is determined that the first connector (140) and the second connector (240) are not connected.

[0067] Subsequently, when it is determined that the first connector (140) and the second connector (240) are connected, the seat controller (10) applies power supply and drive control signals to the electrical components of the electric child seat (200), whereas when it is determined that the first connector (140) and the second connector (240) are not connected, the seat controller (10) applies power supply and drive control signals to the electrical components of the vehicle seat (100).

[0068] For example, if the above operation request is for the second heater mat (210) among the electrical components of the electric child seat (200), if the first connector (140) and the second connector (240) are connected, a power supply and drive control signal is applied to the second heater mat (210) of the electric child seat (200) (S104), and if the first connector (140) and the second connector (240) are not connected, a power supply and drive control signal is applied to the first heater mat (110) of the vehicle seat (100) (S105).

[0069] Accordingly, when the first connector (140) and the second connector (240) are connected, the second heater mat (210) among the electric components of the electric child seat (200) is operated, thereby relieving the discomfort of a child riding in the child seat feeling cold, and providing a comfortable seating environment for the child.

[0070] On the other hand, even if the first connector (140) and the second connector (240) are not connected, the first heater mat (110) of the vehicle seat (100) is operated, thereby providing an indirect heating effect to the infant riding in the child seat.

[0071] For example, if the above operation request is for a second ventilation blower (220) among the electrical components of an electric child seat (200), if the first connector (140) and the second connector (240) are connected, a power supply and drive control signal is applied to the second ventilation blower (220) of the electric child seat (200) (S109), and if the first connector (140) and the second connector (240) are not connected, a power supply and drive control signal is applied to the first ventilation blower (120) of the vehicle seat (100) (S110).

[0072] Accordingly, when the first connector (140) and the second connector (240) are connected, the second ventilation blower (220) among the electrical components of the electric child seat (200) is operated, thereby relieving discomfort such as sweating or feeling hot on the infant's body through ventilation air discharged toward the infant's body, and providing a comfortable seating environment for the infant.

[0073] On the other hand, even if the first connector (140) and the second connector (240) are not connected, the first ventilation blower (120) of the vehicle seat (100) is operated, thereby providing an indirect cooling effect to the infant seated in the child seat.

[0074] Meanwhile, the operation request for the electric component of the above-mentioned electric child seat is checked to see if it has been released (S106, S111), and if there is a release request from the operation request unit, the operation of the corresponding electric component is terminated.

[0075] Figure 9 attached is a flowchart illustrating another example of a control method for an electric child seat for an automobile according to the present invention.

[0076] First, battery power is supplied to the seat controller (10) for control activation according to the vehicle ignition (S201).

[0077] Next, the seat controller (10) determines whether there is an operation request from the operation request unit (20) for an electrical component of the vehicle seat (100) or an electrical component of the electric child seat (200).

[0078] For example, the seat controller (10) determines whether there is a request to operate the motor (231) for reclining adjustment of the electric child seat (200) among the electric components of the electric child seat (S202).

[0079] If, as a result of the judgment in step S202 above, there is a request for operation of the motor (231) for reclining adjustment of the electric child seat (200), the seat controller (10) determines whether to connect the first connector (140) mounted on the vehicle seat (100) and the second connector (240) mounted on the electric child seat (200).

[0080] Next, if the above operation request is a reclining adjustment motor (231) of the electric child seat (200) and the first connector (140) and the second connector (240) are connected, a power supply and drive control signal is applied to the reclining adjustment motor (231) of the electric child seat (200) (S204).

[0081] Accordingly, by operating the reclining adjustment motor (231) of the electric child seat (200), the forward and backward angle of the electric child seat (200) is adjusted, thereby providing convenience for infants to sit and convenience for transitioning to a comfortable position.

[0082] On the other hand, when the first connector (140) and the second connector (240) are connected, power supply and drive control signals are applied to the reclining adjustment motor (131) and the seat cushion tilting motor (133) for adjusting the seat back angle of the vehicle seat (100) (S205).

[0083] Accordingly, when there is a request for operation of the reclining adjustment motor (231) of the electric child seat (200), even if the first connector (140) and the second connector (240) are not connected, when the reclining adjustment of the seat back of the vehicle seat and the tilting adjustment of the seat cushion are performed simultaneously by the operation of the reclining adjustment motor (131) and the tilting motor (133) of the vehicle seat (200), the electric child seat mounted on the vehicle seat can also be reclined together, thereby providing convenience for infants to sit and convenience for transitioning to a comfortable position.

[0084] Figure 10 attached is a flowchart illustrating another example of a control method for an electric child seat for an automobile according to the present invention.

[0085] First, battery power is supplied to the seat controller (10) for control activation according to the vehicle ignition (S201).

[0086] Next, in the second seat controller (12) of the above seat controller (10), it is determined whether a door open signal from the door switch (24) is received from the CAN bus (22) of the above operation request unit (20) and a vehicle stop signal from the vehicle speed sensor (25) is received at the same time (S302).

[0087] For reference, a door panel is typically equipped with a door switch that detects the open or closed state of the door when pressed when the door is closed.

[0088] As a result of the judgment in step S302 above, if the second seat controller (12) receives a door opening signal from the door switch (24) from the CAN bus (22) and simultaneously receives a vehicle stop signal from the vehicle speed sensor (25), the second seat controller (12) applies a power supply and drive control signal to the swivel motor (232) of the electric child seat (200) to rotate the electric child seat toward the door (S303).

[0089] Therefore, when the door is opened or the vehicle stops, the electric child seat automatically rotates toward the direction the door opens, thereby providing convenience for the infant to sit in or disembark from the child seat.

[0090] Next, after a certain period of time, the second seat controller (12) determines whether a door closing signal is received from the door switch (24) via the CAN bus (22) of the operation request unit (20) and whether a vehicle speed detection signal exceeding 0 km / h is received from the vehicle speed sensor (25) at the same time (S304).

[0091] As a result of the judgment in step S304 above, if the second seat controller (12) receives a door closing signal of the door switch (24) from the CAN bus (22) and at the same time receives a vehicle speed detection signal exceeding 0 km / h from the vehicle speed sensor (25), the second seat controller (12) applies a power supply and drive control signal to the swivel motor (232) of the electric child seat (200) to rotate the electric child seat toward the front of the vehicle (S305).

[0092] Accordingly, when the door is closed and the vehicle speed is detected, the electric child seat can be automatically rotated back toward the front of the vehicle for the safety and observation of the infant seated in the child seat.

[0093] Although the present invention has been described in detail with various embodiments above, the scope of the present invention is not limited to each of the embodiments described above, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims are also included within the scope of the present invention.
