BACKGROUND OF THE INVENTION Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a floor lighting control system for a vehicle interior, and more particularly to a floor lighting control system for a vehicle interior that controls light to automatically turn on by detecting a light touch or a movement of a person or an object within a close range.

Generally, a room lamp applied to an automobile is an illuminating lamp that illuminates an interior of a dark vehicle to identify an object or various operation buttons. BACKGROUND ART Automobile room lamps are usually arranged in a top sealing portion, which is a ceiling portion of an automobile interior, and are configured to be automatically turned on in conjunction with lighting through direct manual operation such as switch on / off or opening and closing of a vehicle door.

The door interlocking room lamp lighting system according to the related art includes a door sensor for detecting whether the door is opened or closed and a control unit for automatically lighting the room lamp according to a signal sensed by the door sensor. The door sensor transmits an open signal when the door is opened and a closed signal when the door is closed, and the control unit controls the power source according to the signal received from the door sensor to turn on / off the room lamp.

That is, when the door is opened, the door sensor senses the opening state of the door and sends an open signal. According to a signal of the door sensor, the control unit allows power to be supplied to the room lamp so that the room lamp is turned on, When the door is closed, the door sensor senses the closed state of the door and sends a closing signal, and the control unit turns off the power supply according to the signal of the door sensor to turn off the room lamp.

However, since the room lamp generally adopted in the conventional automobile is disposed in the ceiling of the room as described above, it is difficult to expect a sufficient lighting effect to reach the floor of the room. The seat or the passenger positioned in the middle of the light path creates a shadow on the floor, The floor of the room is dark, and therefore, there is a considerable inconvenience when searching for objects that fall on the floor when driving at night.

Furthermore, since the door lamp must be opened after the on / off switch is directly operated or the door interlocking mode switch is switched to the door interlocking mode in order to light the room lamp, it is not easy to operate the room lamp. It is frequently found that the object that has fallen on the floor is turned on and is recognized as a serious threat to safe driving.

Korean Unexamined Patent Publication No. 2005-0061842 (hereinafter referred to as the "prior art") discloses an illumination system in which a lamp is arranged below a car seat in an automobile interior lighting system to illuminate the floor of a vehicle . This is characterized in that the lamp illuminating the floor of the vehicle is configured to be interlocked with the door sensor so that the door is automatically turned on or off according to opening and closing of the door sensor.

In particular, in the door closed state, the manual switch is operated to directly turn on the lamp. As a result, there is an inconvenience that the switch must be physically operated directly when the door is closed, and since the lamp is turned on when the switch is operated during operation, there is a problem that the risk of safety accidents due to dispersion of concentration, .

Korean Unexamined Patent Publication No. 2005-0061842 (published Jun. 23, 2005)

The illumination control sensing unit 20 detects the degree of operation of the illumination unit 10 by the user. Specifically, the illumination control sensing unit 20 senses an operation intention for lighting the illumination unit 10 through a touch or movement of the user (preferably, a specific gesture) And outputs an electrical signal to the control unit 30 when an operation intention is detected.

The lighting control sensing unit 20 may be mounted such that a part of the control signal is externally exposed to the power seat control module 40 to which an operation force for controlling the operation of the power seat is input so that the user can intuitively operate the power seat.

The capacitance change type touch sensor or the non-contact type proximity sensor (for example, an IR sensor or an RF sensor) may be applied as the illumination control sensing unit 20 and may be activated only when a predetermined condition is satisfied, Lt; / RTI >

The control unit 30 outputs a control signal for controlling the illumination unit 10. Specifically, when a touch or an operation intention is detected, the sensing signal is received from the illumination control sensing unit 20 and is output as a control signal for controlling the lighting unit 10 in the vehicle. In addition, when the predetermined condition is satisfied, the lighting control sensing unit 20 is activated to sense the lighting operation intention of the lighting unit 10. [

In other words, when the predetermined activation condition is satisfied, the illumination control sensing unit 20 is activated by the signal transmitted from the control unit 30 and senses the intention of the user. If the sensing unit is activated only when the predetermined condition is satisfied and the degree of operation for lighting the illumination unit 10 can be detected, unintentional illumination of the illumination unit 10 in a situation where lighting is unnecessary, Can be prevented.

The predetermined condition in which the illumination control sensing unit 20 is activated by the control unit 30 may be a condition that makes lighting of the illumination unit 10 impossible at all during operation. Preferably, the gear position information sent from the gear position sensing unit 50 to the control unit 30 is a parking position P, and information from the seat belt sensing unit 60, which senses whether or not the seat belt is worn, May be the seat belt release.

That is, only when the gear is positioned at the position P and the seat belt is not worn or parked, the control unit 30 controls the operation of the illumination control sensing unit 20 based on a signal sent from the sensing unit The lighting control sensing unit 20 is activated by outputting the control signal to the lighting control sensing unit 20. When the lighting intention of the user is sensed in this state, the lamp 12 is illuminated to illuminate the floor of the vehicle interior .

The system may be configured to further include an electric actuator 70 for driving the electric seat driven by the control of the controller 30. [ In this case, when the touch or movement of the user is detected in a state where the lighting control sensing unit 20 is activated, the control unit controls the lamps 12 ) Are simultaneously performed.

On the other hand, the lighting unit 10 can be extinguished automatically by a control of the control unit 30 after a lapse of an arbitrary time. Of course, the gesture corresponding to the gesture previously input or previously input may be realized by touching the illumination lighting sensing unit by the user again. In addition, the lamp may be turned off in conjunction with lighting of a room lamp that is automatically turned on / off according to the opening of the vehicle door.

The lighting unit lighting for the indoor floor lighting realized through the vehicle floor lighting control system according to the embodiment of the present invention will be briefly described with reference to the control logic.

FIG. 3 is a control logic for floor lighting control performed by the vehicle floor lighting control system according to the present invention, in which the actuator for driving the electric seat operates in association with the result of sensing the user's operation through the lighting control sensing unit, And the lighting unit illuminating the floor of the room is automatically turned off after a predetermined time has elapsed.

Referring to FIGS. 1 and 2 together with FIG. 3, the illumination for the indoor floor lighting of the vehicle by the system of the present invention is performed when the predetermined condition is satisfied and the illumination control sensing unit 20 is activated Is implemented by controlling the lighting unit by the control unit 30, which is executed when the lighting control sensing unit 20 is touched or a specific gesture is taken at a close distance and a lighting operation signal is inputted.

The control unit 30 first determines whether the predetermined condition for activation of the illumination control sensing unit 20 is satisfied based on the information transmitted from each sensing unit. Specifically, when the information transmitted from each of the gear position sensing unit 50 and the seat belt sensing unit 60 is analyzed and it is determined that the gear is positioned at 'P' and it is determined that the seat belt is not in use, It is judged to be satisfied.

If it is determined that the predetermined condition is satisfied, the controller 30 activates the illumination control sensing unit 20 according to a signal transmitted from the controller 30. The control unit 30 transmits the enable signal to the control unit 30 in a true state at the same time that the illumination control sensing unit 20 is activated and accordingly the control unit 30 controls the lighting unit to be turned on and off according to the detection result transmitted from the illumination control sensing unit 20. [ In the state of being able to control.

When the illumination control sensing unit 20 is touched (when a touch sensor is applied) or a specific gesture is taken at a close distance for lighting the mood lamp in a state in which the illumination control sensing unit 20 is activated (when a noncontact proximity sensor is applied , The lighting control sensing unit 20 senses the signal and transmits the signal to the control unit 30. The control unit 30 controls the seat to move back and the lighting unit, specifically, the lamp is turned on.

After the lamp is turned on, the timer is activated to count the lighting time, and when the lighting time of the mood lamp reaches the predetermined recording time, the lamp is turned off and the seat is returned to its original position. Of course, in the case where the automatic light-off method is not employed, the light control sensing unit 20 may be touched again or another specific gesture may be taken to realize the lamp light-off and restoration of the seat.

According to the indoor floor lighting control system of the present invention, since the on / off of the illumination unit is controlled through the proximity sensor (infrared sensor, capacitance sensor) It is possible to secure the ease of lighting operation of the lighting unit as compared with a mechanical switch system, and the convenience can be greatly increased.

Further, since the sensing portion is activated only when the predetermined condition (state in which the gear is in the parking (P) position and the seat belt is released) is satisfied and lighting of the illumination portion is implemented through gesture or light touch, It is possible to prevent the lighting unit from being turned on unintentionally, and it is possible to prevent the dispersion of the concentration of power due to unintentional illumination of the lighting unit and the lowering of the reliability of the system.

Further, since the sensing unit is activated and the lighting unit is turned on only in a safe situation in which the vehicle is stopped or the parking seat is released and the seat belt is released, the lighting unit can not be turned on even if the lighting unit lighting operation is performed during operation Therefore, it is possible to reliably prevent a lighting operation during operation and a safety accident therefrom.

Further, when the lighting control sensing unit for detecting the user's intention to turn on the lighting unit is applied to the in-vehicle power seat control module, there is an advantage in that the lighting unit can be operated more intuitively. The lighting unit is mounted at the lower end of the seat, It is possible to produce a faint indoor atmosphere through the lighting unit, which is effective in terms of the interior, and is effective in finding an object that has fallen on the floor.
