Hereinafter, the execution procedure of lighting control at the time of getting on and off will be described. FIG. 3 shows a specific execution procedure of the on / off lighting control, and a series of processing shown in the flowchart of FIG. 3 is executed by the electronic control unit 40 as processing at predetermined intervals.

  As shown in FIG. 3, in this process, when any one of the driver seat door 31, the passenger seat door 32, and the slide doors 33, 34 is opened (step S11: YES), the room lights 51F, 51C, 51R are turned on. Illuminated (step S12).

  After that, when all the doors 31 to 34 are closed (step S11: NO), the room lights 51F, 51C, 51R are lit (step S13: YES), so the following (light-off condition A) It is determined whether or not at least one of (light-off condition B) is satisfied (step S14 and step S15).

(Light-off condition A) The lighting duration time of each of the room lights 51F, 51C, 51R is not less than the predetermined time T1.
(Light-off condition B) The seat belt sensor 43 detects the wearing of the seat belt in all the seats where the seating sensor 41 detects the seating of the occupant.

  If both (light-off condition A) and (light-off condition B) are not satisfied (step S14: NO and step S15: NO), there is a possibility that the occupant who has ridden the vehicle does not wear a seat belt. The room lights 51F, 51C, and 51R are continuously turned on (step S12), assuming that not much time has passed since all of 31 to 34 are closed.

  Thereafter, when (the light-off condition A) is satisfied (step S14: YES), the room lights 51F, 51C, 51R are turned off, assuming that the lighting times of the room lights 51F, 51C, 51R are longer ( Step S16). On the other hand, if (light-off condition B) is satisfied before (light-off condition A) is satisfied (step S14: NO, and step S15: YES), all the occupants who have ridden seated on the seat and wore seat belts. As a result, the room lights 51F, 51C, 51R are turned off (step S16).

  After the room lights 51F, 51C, 51R are turned off in this way, as long as any one of the driver seat door 31, the passenger door 32, and the slide doors 33, 34 is not opened (step S11: NO, and Step S13: NO), the process of turning on the room lights 51F, 51C, 51R (Step S12) is not executed.

In the present embodiment, opening / closing lighting control for turning on the luggage light 52 when the back door 35 is opened / closed is executed.
Hereinafter, an execution procedure of the open / close lighting control will be described. FIG. 4 shows a specific execution procedure of the open / close lighting control, and a series of processing shown in the flowchart of FIG. 4 is executed by the electronic control unit 40 as processing at predetermined intervals.

  As shown in FIG. 4, in this process, when the back door 35 is opened (step S21: YES), the luggage light 52 is turned on (step S22). Then, when the back door 35 is subsequently closed (step S21: NO), the luggage light 52 is turned off (step S23).

  Here, if the luggage light 52 is not turned on unless the back door 35 is opened, the interior of the passenger compartment 11 is not detected when the vehicle 10 is operating in a dark state (such as when the vehicle stops at an intersection at night). When the luggage space 12 is used, the luggage space 12 is in a dark state, which makes the passenger feel inconvenient. Even if an operation switch for lighting the luggage light 52 is provided in the vicinity of the luggage light 52, the operation of the operation switch becomes troublesome because the interior of the passenger compartment 11 is dark.

  In view of this point, in the present embodiment, control (lighting control during driving) is performed to turn on the luggage light 52 when there is a possibility that an occupant may use the luggage space 12 during driving of the vehicle 10. .

  When the occupant uses the luggage space 12 while the vehicle 10 is in operation, the occupant's operation includes an operation to stand up with the seat belt removed. For this reason, in the above-described lighting control during driving, the state of one seat is detected both when the seat is seated and when the seat belt is worn, and when the seat belt is not worn and when the seat is separated from the seat. It is determined that there is a possibility that the occupant got off the seat belt and got up from the seat while driving the vehicle 10, and that the occupant may use the luggage space 12 as a result. Is done. In addition, it is judged that the vehicle 10 is drive | operating because all the doors 31-35 are closed.

  Through such driving lighting control, the luggage space 12 can be used automatically in a bright state during driving of the vehicle 10, so that the convenience of using the luggage space 12 can be improved.

  Hereinafter, the execution procedure of the lighting control during operation will be described. FIG. 5 shows a specific execution procedure of the on-operation lighting control, and a series of processing shown in the flowchart of FIG. 5 is executed by the electronic control unit 40 as processing at predetermined intervals.

  As shown in FIG. 5, in this process, it is first determined whether or not all the doors 31 to 35 are closed (step S31). If any of the doors 31 to 35 is opened (step S31: NO), the following processing is performed because the vehicle 10 is not in operation, such as when passengers get on and off or load and unload luggage. Is not executed.

  On the other hand, when all the doors 31 to 35 are closed (step S31: YES), when the luggage light 52 is turned off (step S32: YES), the rear seats (the right seats 22R and 23R and the left side) It is determined whether any of the seats 22L and 23L has shifted from the following (state A) to (state B) (step S33).

(State A) Seating on the seat is detected by the seating sensor 41 and wearing of the seatbelt is detected by the seatbelt sensor 43.
(State B) The seating sensor 41 detects the separation from the seat, and the seatbelt sensor 43 detects that the seatbelt is not worn.

  If none of the rear seats has shifted from (State A) to (State B) (Step S33: NO), the luggage light 52 and the room light 51R are not turned on (Step S34 and Step S35). This process is temporarily ended.

  Thereafter, when any state of the rear seat shifts from (State A) to (State B) (Step S33: YES), on condition that the traveling speed of the vehicle 10 is less than a predetermined speed (for example, 2 km per hour) ( Step S34: YES), the luggage light 52 and the rear room light 51R are turned on (step S35). In the process of step S35, the luminous flux of the luggage light 52 is made smaller than the luminous flux of the luggage light 52 during lighting by the open / close lighting control (step S22 in FIG. 4), and the luminous flux of the room light 51R is lit when getting on and off. It is made smaller than the luminous flux of the room light 51R during lighting by control (step S12 in FIG. 3).

  In this process, when the traveling speed of the vehicle 10 is equal to or higher than the predetermined speed (step S34: NO), the luggage light 52 and the room light 51R are not turned on because the vehicle 10 is in a traveling state (the process of step S35 jumps). )

  According to this process, when the occupant removes the seat belt and stands up from the rear seat while driving the vehicle 10, the occupant may use the luggage space 12, and the luggage light 52 and the rear room The light 51R can be turned on. Thereby, the luggage space 12 can be used in a state where the interior of the passenger compartment 11 is automatically brightened when the vehicle 10 is operated in a dark state (such as when the vehicle stops at an intersection at night). Therefore, the convenience concerning the use of the luggage space 12 can be improved.

  Further, according to this processing, the room light 51R as the rear light that illuminates the rear part in the passenger compartment 11 is turned on in accordance with the lighting of the luggage light 52. Thereby, in addition to illuminating the luggage space 12, it is possible to illuminate the vicinity of the luggage space 12, so that the convenience of using the luggage space 12 such as easy access and movement to the luggage space 12 is suitable. Can be improved. In the case of a vehicle in which the third row seat 23 can be folded, when the third row seat 23 is folded, the portion that has been developed before the third row seat 23 is folded also becomes a luggage space. In such a case, the entire luggage space can be illuminated by the luggage light 52 and the room light 51R.

  In this process, when the luggage light 52 and the room light 51R are turned on while the vehicle 10 is in operation (step S31: YES and step S32: NO), at least one of the following (light-off condition C) and (light-off condition D) is It is determined whether or not the conditions are satisfied (step S36 and step S37).

(Light-off condition C) The lighting continuation time of the luggage light 52 and the room light 51R is equal to or longer than the predetermined time T2.
(Light-off condition D) While the luggage light 52 and the room light 51R are lit, the state of any of the rear seats (the right seats 22R, 23R and the left seats 22L, 23L) is changed from the (state B) to the (state A). What you did.

  And when these (light extinction condition C) and (light extinction condition D) are not satisfy | filled (step S36: NO and step S37: NO), the passenger | crew has left the seat in the vehicle interior 11. Yes, the lights 52 and 51R are continuously turned on, assuming that not much time has passed since the luggage light 52 and the room light 51R are turned on.

  Thereafter, when the (light-off condition C) is satisfied (step S36: YES), the lights 52 and 51R are turned off, assuming that the lighting time of the luggage light 52 and the room light 51R is long (step S38). Thereby, it is suppressed that the luggage light 52 and the room light 51R remain unlit for an unnecessarily long time.

  On the other hand, if (the light extinction condition D) is satisfied before (the light extinction condition C) is satisfied (step S36: NO, and step S37: YES), the occupant who has once removed the seat belt and sat back is seated again. Assuming that the seat belt is attached, the luggage light 52 and the room light 51R are turned off (step S38).

  According to the present processing, the luggage light 52 and the room light 51R that are turned on through the driving lighting control are loaded by the passenger when the passenger who has left the seat belt once has reseated the seat and put on the seat belt. When the use of the space 12 is finished, it can be turned off. In this manner, the luggage light 52 and the room light 51R can be automatically turned off in accordance with the use situation of the luggage space 12 by the occupant.

  Moreover, even when the use of the luggage space 12 is finished and the occupant re-sits in the seat, when the occupant does not wear the seat belt, the luggage light 52 and the room light 51R are lit without being turned off. Therefore, it is possible to prompt the wearing of the seat belt by causing the passenger to feel uncomfortable due to this situation.

As described above, according to the present embodiment, the following effects can be obtained.
(1) When the closed state of all the doors 31 to 35 is detected, the state of one seat is determined from the state in which both seating on the seat and wearing of the seat belt are detected. The luggage light 52 is turned on when the state shifts to a state where both wearing and separation from the seat are detected. Thereby, since the luggage space 12 can be used in a state where it is automatically brightened during the operation of the vehicle 10, the convenience of using the luggage space 12 can be improved.

  (2) The room light 51R is turned on in accordance with the lighting of the luggage light 52 in the lighting control during operation.
