FIG. 1 is an explanatory view showing the arrangement of an in-vehicle state confirmation device according to an embodiment of the present invention.

  As shown in FIG. 1, the vehicle 1 is provided with map lamps 21 and 23 corresponding to the driver's seat 3 and the passenger's seat 5 disposed in the front passenger compartment 2 at the front center of a roof liner (not shown) in the vehicle. It is done. Further, in the rear compartment 6 of the vehicle 1 located behind the driver's seat 3 and the passenger seat 5, reading lights 25 to 31 (corresponding to the rear compartment illumination in the claims) and ceiling lights 33 and 35 (invoices) (Corresponding to the rear passenger compartment illumination in the section) is provided on both the left and right sides of the roof flyer (not shown). The reading lamps 25 to 31 and the ceiling lights 33 and 35 and their lighting control system constitute an in-vehicle state confirmation device according to an embodiment of the present invention.

  Each of the reading lights 25 to 31 illuminates the second row and third row seats 7, 9, and 11 (however, the third row seat 11 illuminates seats at both ends of a three-seater seat). In the present embodiment, each of the reading lamps 25 to 31 is configured by an LED that is lit with a predetermined lighting color, and is configured so that the light emission brightness can be changed.

  The ceiling lights 33 and 35 are rod-shaped light guides 33a and 35a that are linearly arranged along the left and right sides of the roof flyer (not shown), and light is incident on the inside from the front and rear ends of the light guides 33a and 35a. Light sources 33b and 35b. Each of the light sources 33b and 35b is composed of three LED chips of RGB, and is configured to be able to change the lighting color and light emission brightness.

  FIG. 2 is an explanatory diagram schematically showing a schematic configuration of the lighting control system of the reading lamps 25 to 31 and the ceiling lights 33 and 35. As shown in FIG. 2, each of the reading lights 25 to 31 is connected to a controller via a signal wiring S such as an in-vehicle LAN arranged around the ceiling of the vehicle 1 together with switches 25 a to 31 a arranged in the vicinity thereof. 37. The light sources 33b and 35b of the ceiling lights 33 and 35 are also connected to the controller 37 via the signal wiring S. The controller 37 is also connected with a switch 39 a and a color designation switch 39 b of the ceiling lights 33 and 35 through a signal wiring S.

  The controller 37 causes the reading lights 25 to 31 to emit light with brightness according to the operation of the corresponding switches 25a to 31a. In addition, the controller 37 causes both ceiling lights 33 and 35 to emit light with the brightness according to the operation of the switch 39a and the lighting color according to the operation of the color designation switch 39b. Further, the controller 37 is provided when the confirmation switch 20 (corresponding to an operation unit in the claims) provided on, for example, a dashboard (not shown) of the front compartment 2 is operated while the vehicle 1 is stopped. The reading lights 25 to 31 and the ceiling lights 33 and 35 are turned on for a predetermined period in the confirmation mode.

  In addition, lighting of each reading lamp 25-31 and each ceiling lighting 33, 35 in confirmation mode is a pattern which lights each reading lamp 25-31 and ceiling lighting 33, 35 with the brightness of half of the maximum brightness, for example. It can be.

  A shift range signal indicating the shift range of the vehicle 1 and an IGN signal indicating the position of an ignition switch (not shown) are input to the controller 37 described above via a vehicle LAN (not shown) at regular intervals. Instead of these signals or together with these signals, a parking brake signal indicating on / off of the parking brake may be inputted. Based on these signals, the switches 25 a to 31 a of the reading lights 25 to 31, the switches 39 a of the ceiling lights 33 and 35, the color designation switch 39 b, and the operation state of the confirmation switch 20, the controller 37 The lighting of 25-31 and ceiling lighting 33 and 35 is controlled.

  For this purpose, the controller 37 has a CPU, a RAM, a ROM, etc. (all not shown). And according to the program stored in ROM, CPU controls lighting of the light sources 33b and 35b of each reading lamps 25-31 and the ceiling lights 33 and 35 using RAM as a work area.

  Next, referring to the flowchart of FIG. 3, the procedure of lighting control of the reading lamps 25 to 31 and the light sources 33 b and 35 b of the ceiling lights 33 and 35 executed by the CPU of the controller 37 according to the program stored in the ROM. I will explain. The CPU repeatedly executes the control of the procedure shown in the flowchart of FIG. 3 at predetermined intervals.

  First, the CPU confirms whether or not the switches 25a to 31a corresponding to any of the reading lamps 25 to 31 are on (step S1), and if all of the switches 25a to 31a are not on (in step S1). NO), the process proceeds to step S5 described later.

  When at least one of the switches 25a to 31a is on (YES in step S1), the CPU switches the reading lamps 25 to 31 corresponding to the switches 25a to 31a that are on to the operation state of the switches 25a to 31a. The lighting is performed with the corresponding brightness (step S3), and the process proceeds to step S5.

  In step S5, the CPU checks whether or not the switch 39a of the ceiling lights 33 and 35 is on. If not (NO in step S5), the CPU proceeds to step S9 described later.

  When the switch 39a is on (YES in step S5), the CPU turns on the light sources 33b and 35b with the brightness corresponding to the operation state of the switch 39a and the lighting color corresponding to the operation state of the color designation switch 39b. After lighting both the ceiling lights 33 and 35 (step S7), the process proceeds to step S9.

  In step S9, the CPU confirms whether or not the confirmation switch 20 is operated. If not (NO in step S9), the CPU ends the series of processes.

  If the confirmation switch 20 is operated (YES in step S9), the CPU confirms whether the vehicle 1 is traveling or stopped from the contents of the shift range signal, the IGN signal, and the like ( Step S11).

  When the vehicle 1 is traveling (YES in step S11), the series of processes is terminated, and when the vehicle 1 is stopped (NO in step S11), the CPU reads the reading lights 25 to 31 and the ceiling lights 33 and 35. Is turned on in the confirmation mode (step S13), and it is confirmed from the contents of the shift range signal, the IGN signal, and the like whether or not the vehicle 1 has started running (step S15).

  If the vehicle 1 has started running (YES in step S15), the process proceeds to step S19 described later. If the vehicle 1 has not started running (NO in step S15), a certain period of time has elapsed from the operation of the confirmation switch 20. It is confirmed whether or not elapses (step S17).

  If the predetermined time has not elapsed since the operation of the confirmation switch 20 (NO in step S17), the process returns to step S15. If the predetermined time has elapsed since the operation of the confirmation switch 20 (YES in step S17), Control goes to step S19.

  In step S19, the reading lamps 25 to 31 and the ceiling lights 33 and 35 that are turned on in the confirmation mode are turned off, and then a series of processing ends.

  As is clear from the above description, in the present embodiment, the procedure of steps S13 to S19 in the flowchart of FIG. 3 performed by the CPU of the controller 37 is a procedure corresponding to the illumination control unit in the claims. .

  As described above, in this embodiment, when the confirmation switch 20 is operated while the vehicle 1 is stopped, the reading lamps 25 to 31 and the ceiling lights 33 and 35 are turned on at half the maximum brightness. The reading lights 25 to 31 and the ceiling lights 33 and 35 are turned off when the vehicle 1 starts running or when a certain time elapses from the operation of the confirmation switch 20 while the vehicle 1 is stopped.

  For this reason, when the passengers in the driver's seat 3 and the passenger seat 5 in the front compartment 2 of the vehicle 1 want to confirm the state of the passengers in the seats 7, 9, 11 in the rear compartment 6, the passengers in the seats 7, 9, 11 The lights of the reading lights 25 to 31 and the ceiling lights 33 and 35 are turned on darkly so that the passengers in the rear passenger compartment 6 can be seen by looking back and looking into the room mirror (not shown). Can be confirmed.

  Therefore, the rear passenger compartment 6 has a simple configuration in which the existing reading lights 25 to 31 and the ceiling lights 33 and 35 are lit darkly without using a large-scale configuration such as image processing of a captured image of the rear passenger compartment 6. It is possible to make the passengers in the front passenger compartment 2 confirm the state of the passengers.

  Further, when the vehicle 1 starts traveling or when a certain time has elapsed from the operation of the confirmation switch 20 while the vehicle 1 is stopped, the reading lights 25 to 31 and the ceiling lights 33 and 35 are turned off. After confirming the state of the occupant, the operation of turning off the reading lamps 25 to 31 and the ceiling lights 33 and 35 is omitted, and the reading lamps 25 to 31 and the ceiling lighting 33 are appropriately timed. , 35 can be turned off.

  It should be noted that the conditions for turning off the reading lights 25 to 31 and the ceiling lights 33 and 35 that are turned on by the operation of the confirmation switch 20 are only one of the start of traveling of the vehicle 1 and the passage of a certain time from the operation of the confirmation switch 20. It is good also as conditions other than these.

  The present invention is extremely useful when a passenger in a driver's seat or a passenger seat of a vehicle confirms the state of a rear passenger compartment by configuration.
