The present application claims priority to Korean Patent Application No. 10-2022-0085743, filed on Jul. 12, 2022, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to a convenience apparatus for a rear seat passenger and an operation control method thereof, and more particularly to a rear seat passenger convenience apparatus allowing a rear seat passenger to determine use of a heating function, a ventilation function or a foot massage function provided in a front seat in accordance with an open angle of a footrest provided at the front seat, and an operation control method of the same.
In a vehicle, a seat, on which a passenger may be accommodated, is provided. The seat of the vehicle includes a seat cushion configured to support a lower body of the passenger, a seatback configured to support an upper body of the passenger, and a headrest configured to support a head of the passenger.
For an enhancement in rear seat passenger convenience, a footrest may be provided at a backboard coupled to a seatback of a front seat (including a driver's seat and a passenger seat) so that the footrest is pivotable rearwards to protrude rearwards thereof.
Furthermore, a seat convenience device for a rear seat passenger may be provided in the seatback of the front seat. In the instant case, the seat convenience device may include a heating function through a heating wire, a ventilation function through a blower and a foot massage function through a foot massage machine.
Upon using the seat convenience device provided in the front seat, the rear seat passenger first opens the footrest, and then lays the feet on the footrest, and accordingly, may use the seat convenience device.
However, conventional seat convenience devices are configured to operate or to stop operation in accordance with a desire of the user, irrespective of an open angle of a footrest. For the present reason, when malfunction occurs in a closed state of the footrest, there may be a high danger of fire due to overheating in the case of a heating function, and there may be problems of generation of severe noise and degradation in durability in the case of a foot massage function. Furthermore, there may be a drawback in that electric power is unnecessarily consumed due to activation of functions under non-use conditions (in a closed state of the footrest).
The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present disclosure are directed to providing a convenience apparatus for a rear seat passenger and an operation control method thereof, in which, when an open angle of a footrest of a front seat does not satisfy a predetermined reference angle under the condition that the rear seat passenger desires to use the seat convenience device (including heating, ventilation and foot massage functions) provided in the front seat, operation of the seat convenience device is disabled in spite of the user's desire, and accordingly, is prevented under non-use conditions, not only achieving prevention of fire and damage to parts caused by misuse of the seat convenience device and an enhancement in durability, but also achieving a reduction in unnecessary electric power consumption.

Hereinafter, the operation method of controlling the rear seat passenger convenience apparatus according to the exemplary embodiment of the present disclosure will be described with reference to
The operation method of controlling the rear seat passenger convenience apparatus according to the exemplary embodiment of the present disclosure includes an opening step of opening the footrest 50 by a footrest open signal generated in accordance with manipulation of the touchscreen 200, a primary determination step of determining whether or not an open angle of the footrest 50 is not smaller than a reference angle, an activation step of activating a manipulation switch of the seat convenience device 100 on the screen of the touchscreen 200, and an operating step of operating the seat convenience device 100 in accordance with manipulation of the activated manipulation switch.
When the rear seat passenger 3 manipulates the touchscreen 200 of the armrest a footrest open signal is generated (step S1), and the generated footrest open signal is transmitted to the seat controller 300 (step S2). The seat controller 300 then sends a control signal to the footrest driving mechanism 400, driving the footrest driving mechanism 400, and, accordingly, the footrest 50 performs an opening operation in accordance with driving of the footrest driving mechanism 400 (step S3: opening step).
When the footrest motor 410 operates under control of the seat controller 300, the Hall sensor provided in the footrest motor 410 detects an open angle of the footrest and the detected open angle of the footrest 50 is transmitted to the seat controller 300. The seat controller 300 then determines whether the open angle of the footrest 50 received from the Hall sensor is not smaller than the reference angle (step S4: primary determination step).
The reference angle is a minimum open angle of the footrest 50 in a state in which the rear seat passenger 3 can lay his or her feet on the opened footrest 50. For example, a state in which the footrest 50 pivots 50° rearwards with reference to a state in which the footrest 50 is closed as the footrest 50 is brought into close contact with the backboard 40 may be set to the reference angle, without being limited thereto.
When the footrest 50 is opened at an open angle not smaller than the reference angle, a passenger 3 of the rear seat 2 may rest in a state of laying his or her feet on the opened footrest 50.
Furthermore, upon determining that the open angle of the footrest 50 is not smaller than the reference angle, in accordance with determination results of the primary determination step (step S4), the seat controller 300 transmits a control signal to the touchscreen 200 and the convenience device controller 500.
When the touchscreen 200 receives the signal from the seat controller 300, manipulation switches including various shapes, which will be manipulated for operation of the seat convenience device 100, are activated on the screen of the touchscreen 200 (step S5: activation step).
When the convenience device controller 500 receives the signal from the seat controller 300, the convenience device controller 500 enters a state of completing preparation for generating a control signal for operation of the convenience device driving mechanism 600.
When one manipulation switch is activated on the screen of the touchscreen 200, the user manipulates the activated manipulation switch, operating a desired unit of the seat convenience device 100 (step S6).
The seat convenience device 100 is provided in the front seat 1, and includes the heater 110, the ventilator 120 and the foot massage machine 130, which may provide convenience to the rear seat passenger 3 in a state in which the rear seat passenger 3 lays his or her feet on the opened footrest 50. The user may operate the heater 110, the ventilator 120 or the foot massage machine 130 of the seat convenience device 100 by manipulating the manipulation switch activated on the touchscreen 200, and accordingly, may get desired convenience (step S7: operating step).
Meanwhile, although the user may operate the seat convenience device 100 by manipulating the manipulation switch activated on the touchscreen 200, the convenience device driving mechanism 600 may also be driven under control of the seat controller 300 and the convenience device controller 500 when the footrest 50 performs an opening operation in accordance with manipulation of the touchscreen 200 by the user so that the footrest 50 is opened at an open angle not smaller than the reference angle, and a signal from a seatback reminder (SBR) sensor of the rear seat 2 is transmitted to the seat controller 300, and, accordingly, the seat convenience device 100 may be driven by the convenience device driving mechanism 600 (steps S6 and S7).
The SBR sensor is used as a reference for determining whether or not a passenger has been accommodated on the rear seat 2.
When the seat convenience device 100 operates in the operating step S7, the user may additionally manipulate a switch, etc. to operate a rear seat heating wire and ventilator 700. In the instant case, a rear seat heating wire, a rear seat ventilator or at least one of the rear seat heating wire or the rear seat ventilator may operate together with the seat convenience device 100, and accordingly, all passengers accommodated on the rear seat 2 may get convenience.
Meanwhile, when the open angle of the footrest 50 is determined to be smaller than the reference angle, in accordance with determination results of the primary determination step S4, the manipulation switch for the seat convenience device 100 is inactivated on the screen of the touchscreen 200 under control of the seat controller 300 (inactivation step). When the screen of the touchscreen 200 is inactivated, the passenger cannot manipulate the manipulation switch, and accordingly, operation of the seat convenience device 100 is disabled (step S8).
After the inactivation step S8, the seat controller 300 determines whether or not failure of a footrest operating system including the footrest driving mechanism 400 has occurred (step S9). Upon determining that failure has occurred in accordance with determination results of step S9, the control logic of the present disclosure is ended. On the other hand, upon determining that there is no failure, the control logic is fed back to the step preceding the primary determination step (step S4), and then continuously proceeds in accordance with a provided sequence.
When the user additionally manipulates a switch, etc., for operation of the rear seat heating wire and ventilator 700 under the condition that operation of the seat convenience device 100 is disabled due to the inactivation step (step S8), the rear seat heating wire or the rear seat ventilator operates alone irrespective of the seat convenience device 100, and accordingly, some of the passengers accommodated on the rear seat 2 may get convenience through operation of the rear seat heating wire and ventilator 700.
Meanwhile, the control logic according to an exemplary embodiment of the present disclosure includes a secondary determination step (step S10) of determining whether or not an operation end signal for the seat convenience device 100 has been generated after the operating step (step S7).
Upon determining that the end signal has been generated in accordance with determination results of the secondary determination step (step S10), the seat controller 300 sends a control signal to the convenience device controller 500, and operation of the convenience device driving mechanism 600 is then ended under control of the convenience device controller 500, and accordingly, driving of the seat convenience device 100 is ended (step S11: driving ending step).
Furthermore, when driving of the seat convenience device 100 is ended through the driving ending step (step S11), the opened footrest 50 pivots forwards simultaneously with the driving ending so that the footrest 50 is brought into close contact with the seatback 20, and, accordingly, the footrest 50 is closed (step S12: closing step).
On the other hand, upon determining that no end signal has been generated in accordance with determination results of the secondary determination step (step S10), a third determination step (step S12) of determining whether or not the open angle of the footrest 50 is smaller than the reference angle is further executed. Upon determining that the open angle of the footrest 50 is not smaller than the reference angle in accordance with determination results of the third determination step (step S12), the control logic is fed back to the operating step (step S7). On the other hand, upon determining that the open angle of the footrest 50 is smaller than the reference angle, the control logic is fed back to the driving ending step (step S11), and then proceeds in accordance with a provided sequence.
As described above, in accordance with the exemplary embodiment of the present disclosure, the seat convenience device 100 (including the heater, the ventilator and the foot massage machine) is provided in the front seat 1. When an open angle of the footrest 50 of the front seat 1 does not satisfy a predetermined reference angle under the condition that the rear seat passenger 3 desires to use the seat convenience device 100, operation of the seat convenience device 100 is disabled in spite of the user's desire, and accordingly, is prevented under non-use conditions. Accordingly, it may be possible to not only achieve prevention of fire and damage to parts caused by misuse of the seat convenience device 100 and an enhancement in durability, but also to achieve a reduction in unnecessary electric power consumption.
Furthermore, in accordance in accordance with the exemplary embodiment of the present disclosure, there is a configuration configured for operating the seat convenience device 100 by use of a signal representing whether or not a rear seat passenger 3 has been accommodated, through the SBR sensor, under the condition that use of the seat convenience device 100 is enabled. Accordingly, the configuration for realizing driving conditions of the seat convenience device 100 may be simplified, and accordingly, there are advantages in that a reduction in cost may be achieved, and an enhancement in use convenience may be achieved.
