(First embodiment)

  FIG. 1 is a block diagram illustrating a configuration of a seat belt warning device according to the first embodiment, and FIG. 2 is a diagram illustrating a schematic mounting position of a vehicle of the seat belt warning device according to the first embodiment.

  As shown in FIG. 1, the seat belt warning device 10 according to the present embodiment includes a control unit 12 that performs warning control when an occupant gets on and the seat belt is not attached. In this embodiment, a case where a warning is given when the seat belt of the rear seat is not attached will be described as an example, but it is not limited to the rear seat, and a front seat such as a driver seat or a passenger seat is targeted for warning. Alternatively, all seats may be targeted for warning.

  The control unit 12 includes a CPU 12A, a ROM 12B, a RAM 12C, a nonvolatile memory 13 as a storage unit, and a microcomputer in which an I / O (input / output interface) 12D is connected to a bus 12E.

  The ROM 12B stores various programs such as a program for performing warning control when the seat belt is not attached. Various programs such as warning control are performed by developing a program stored in the ROM 12B in the RAM 12C and executing it by the CPU 12A.

  Connected to the I / O 12D are a camera 14 as an imaging unit, a touch panel 20 as a release instruction unit, a buckle switch 22 as a detection unit, a seating detection unit 24 as a detection unit, and a vehicle speed sensor 26. In addition, a seat belt indicator 28 as a warning unit and an indicator display unit and a warning sound generation unit 30 as a warning unit are connected to the I / O 12D.

  For example, as shown in FIG. 2, the camera 14 is provided at a rear-viewing room mirror mounting portion or the like, captures a rear seat in the passenger compartment, and outputs a captured image to the control unit 12. In this embodiment, an example in which the camera 14 captures the rear seat will be described. However, all seats may be captured. Further, the camera 14 may be provided on a ceiling such as a room lamp mounting portion instead of the rear mirror mounting portion.

  As shown in FIG. 2, the touch panel 20 is provided at the center of the instrument panel and the like, and includes a display unit 18 that displays an image and an operation unit 16 that serves as an instruction unit that performs an operation input through a touch operation. .

  The buckle switch 22 is provided in a buckle that engages with a seat belt tongue in each seat, detects the presence or absence of the seat belt by detecting the insertion of the tongue into the buckle, and outputs the detection result to the control unit 12 To do.

  The seating detection unit 24 is provided in each of the plurality of seats of the vehicle, detects seating of the occupant, and outputs the detection result to the control unit 12. The seating detection unit 24 detects the seating of an occupant using, for example, a pressure sensitive switch or a capacitance sensor. Specifically, the seating detection unit 24 detects objects including passengers and luggage on the seat.

  The vehicle speed sensor 26 detects the vehicle speed when the vehicle travels, and outputs the detection result to the control unit 12.

  As shown in FIG. 1, the seat belt indicator 28 is provided at the center portion of the instrument panel, and displays an image indicating that the seat belt is not attached according to an instruction from the control unit 12. Specifically, the image is displayed by turning on the backlight provided on the back side of the image indicating that the seat belt is not worn for each seat. In addition, it is good also as a structure which lights a lamp instead of an image. Moreover, although the seat belt indicator 28 shows the example provided below the touch panel 20 in this embodiment, you may provide it in another position.

  The warning sound generating unit 30 generates a warning sound indicating that the seat belt is not attached according to an instruction from the control unit 12. For example, the warning sound generation unit 30 may generate a warning sound such as a buzzer or a warning message.

  Here, warning control performed by the control unit 12 when the seat belt is not attached will be described.

  The control unit 12 detects whether or not the seat belt is attached to each seat of the rear seat from the detection result of the buckle switch 22. Further, the control unit 12 detects the presence / absence of an object including the occupant's seating on each seat from the detection result of the seating detection unit 24. Then, the control unit 12 controls the seat belt indicator 28 and the warning sound generation unit 30 to start display and sound when the vehicle starts running in a state where an object is detected by the seating detection unit 24 in a seat with no seat belt. To warn that the seat belt is not worn.

  By the way, since there are many opportunities for the rear seats to carry luggage, the seating detection unit 24 cannot distinguish between an occupant and a luggage, so that even when the luggage is loaded, the user is warned that the seat belt is not attached. However, since the warning is started after traveling, the driver cannot cope with the warning.

  Therefore, in the present embodiment, there is provided a configuration that can issue an instruction to cancel the warning when the occupant recognizes that the object on the seat is a luggage. Specifically, a captured image of the rear seat captured by the camera 14 is displayed on the display unit 18 of the touch panel 20. An instruction area for instructing the cancellation of the warning is provided in a portion corresponding to each seat displayed on the display unit 18, and a touch operation on the instruction area is detected by the operation unit 16. That is, the occupant can cancel the warning by touching the designated area of the seat corresponding to the luggage while confirming the captured image displayed on the display unit 18. As a result, the occupant confirming the object on the rear seat can cancel the warning that the seat belt is not worn.

  For example, when the luggage is placed on the rear seat and the traveling is started, as shown in FIG. 3, a photographed image of the rear seat is displayed on the display section 18, and the seat on which the luggage of the seat belt indicator 28 is placed. An image A such as a mark indicating that the seat belt is not attached is displayed in a portion corresponding to. Then, when traveling is started, the control unit 12 controls to generate a warning sound. Here, as shown in the lower part of FIG. 3, when the occupant touch-operates the pointing area (the portion indicated by the dotted circle in FIG. 3) corresponding to the seat on which the load on the touch panel 20 is placed, as shown in the lower part of FIG. The display of the indicator 28 is turned off, and the control unit 12 controls to stop the warning sound and cancels the warning. This makes it possible to release the warning when the occupant recognizes that the object on the seat is a luggage.

  Next, specific processing performed by the control unit 12 of the seatbelt warning device 10 according to the present embodiment configured as described above will be described. FIG. 4 is a flowchart illustrating an example of a flow of processing performed by the control unit 12 of the seat belt warning device 10 according to the first embodiment. Note that the processing in FIG. 4 starts when, for example, an ignition switch (not shown) is turned on.

  In step 100, the control unit 12 detects the wearing of the occupant's seat belt and proceeds to step 102. That is, the control unit 12 detects the state of the buckle switch 22 of each seat of the rear seat.

  In step 102, the control unit 12 determines whether there is a seat in which the occupant's seat belt is not worn. In this determination, the control unit 12 determines whether or not there is a seat with the buckle switch 22 turned off. If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process proceeds to step 122. .

  In step 104, the control unit 12 detects the seating of the occupant in each seat and proceeds to step 106. That is, the control unit 12 acquires the detection result of the seating detection unit 24 and detects an object including an occupant and luggage on each seat of the rear seat.

  In step 106, the control unit 12 determines whether or not seating on a seat with no seat belt is detected. In this determination, the control unit 12 determines whether or not there is a seat in which the occupant is seated but the seat belt is not worn. If the determination is affirmative, the process proceeds to step 108 and is denied. If YES, go to step 122.

  In step 108, the control unit 12 controls the seat belt indicator 28 to display the image A indicating that the seat belt is not worn, and the process proceeds to step 110.

  In step 110, the control part 12 determines whether it is drive | working. This determination determines whether the vehicle speed detected by the vehicle speed sensor 26 is equal to or higher than a predetermined vehicle speed. If the determination is affirmative, the process proceeds to step 112. If the determination is negative, the process returns to step 100 and the above-described processing is repeated. In addition, the vehicle speed which represents driving | running | working is applied suitably as a predetermined vehicle speed, for example, vehicle speeds, such as 5-10 km / h, can be applied.

  In step 112, the control unit 12 controls to acquire a captured image captured by the camera 14 and display it on the display unit 18, and the process proceeds to step 114. As a result, the photographed image of the rear seat is displayed on the display unit 18 so that the occupant can confirm an object such as a luggage or an occupant on the rear seat.

  In step 114, the control unit 12 controls the warning sound generating unit 30 to generate a warning sound, and proceeds to step 116.

  In step 116, the control unit 12 determines whether or not a warning cancellation instruction has been issued. In this determination, the control unit 12 determines whether the instruction area displayed on the display unit 18 of the touch panel 20 is operated by the operation unit 16. If the determination is affirmative, the process proceeds to step 118. If the determination is negative, the process returns to step 100 and the above-described processing is repeated.

  In step 118, the control unit 12 stores information indicating that the warning is released by the occupant as a release history in a memory such as the nonvolatile memory 13, and proceeds to step 120. This makes it possible to confirm whether or not the warning has been canceled according to the will of the passenger.

  In step 120, the control unit 12 controls the seat belt indicator 28 and the warning sound generating unit 30 to turn off the seat belt indicator 28 and stop the warning sound, and the series of processing ends. Only the warning sound may be stopped.

  On the other hand, in step 122, it is determined whether or not the control unit 12 is in a warning state. In this determination, the control unit 12 determines whether or not a warning that the seat belt is not worn is performed in the above steps. If the determination is affirmative, the process proceeds to step 120 to stop the warning (turn off the seat belt indicator 28 and stop the warning sound) and end the series of processes. If the determination is negative, the series of processes is continued. Exit.

  As described above, in the present embodiment, when there is a seat that has been seated and is detected without being seated, a warning is given that the seat belt is not seated. Here, when the occupant recognizes that the seating is detected by the baggage, the warning is given by operating the instruction area of the corresponding seat displayed on the display unit 18 while checking the display unit 18. It can be canceled. That is, when the seated occupant is not wearing the seat belt, the warning can be reliably detected and the warning can be canceled when the occupant recognizes the baggage.

  In the above-described embodiment, an example in which the warning is canceled by operating the touch panel 20 has been described. However, the present invention is not limited to this. For example, a warning cancellation switch or the like may be provided to cancel the warning.

  In addition, the process performed by the control unit 12 in the above embodiment may be a process of performing detection of seat belt attachment and seating detection again during high speed traveling. For example, steps 124 and 126 may be added as shown in FIG.

  That is, when the seat belt indicator is turned off and the warning sound is stopped at step 120, and when step 122 is denied, the routine proceeds to step 124.

  In step 124, it is determined whether the control unit 12 is traveling at high speed. The determination is made by the vehicle speed sensor 26 as to whether or not the vehicle speed is higher than a predetermined vehicle speed (for example, 80 km / h, etc.). If so, go to Step 126.

  In step 126, the control unit 12 determines whether or not an ignition switch (IG) (not shown) is turned off. If the determination is negative, the process proceeds to step 124. If the determination is affirmative, the series of processing ends. To do.

  In step 100, the control unit 12 detects the wearing of the occupant's seat belt and proceeds to step 102. That is, the control unit 12 detects the state of the buckle switch 22 of each seat.

  In step 102, the control unit 12 determines whether there is a seat in which the occupant's seat belt is not worn. In this determination, the control unit 12 determines whether or not there is a seat with the buckle switch 22 turned off. If the determination is affirmative, the process proceeds to step 104. If the determination is negative, the process proceeds to step 122. .

  In step 104, the control unit 12 detects the seating of the occupant in each seat and proceeds to step 106. That is, the control unit 12 acquires the detection result of the seating detection unit 24 and detects an object including an occupant and luggage on each seat of the rear seat.

  In step 106, the control unit 12 determines whether or not seating on a seat with no seat belt is detected. In this determination, the control unit 12 determines whether or not there is a seat in which the occupant is seated but the seat belt is not worn. If the determination is affirmative, the process proceeds to step 108 and is denied. If YES, go to step 122.

  In step 108, the control unit 12 controls the seat belt indicator 28 to display the image A indicating that the seat belt is not worn, and the process proceeds to step 110.

  In step 110, the control part 12 determines whether it is drive | working. This determination determines whether the vehicle speed detected by the vehicle speed sensor 26 is equal to or higher than a predetermined vehicle speed. If the determination is affirmative, the process proceeds to step 114. If the determination is negative, the process returns to step 100 and the above-described processing is repeated. The predetermined vehicle speed is a vehicle speed indicating that the vehicle is traveling, and for example, a vehicle speed of 5 to 10 km / h can be applied.

  In step 114, the control unit 12 controls the warning sound generating unit 30 to generate a warning sound, and proceeds to step 115.

  In step 115, the control unit 12 acquires a photographed image photographed by the camera 14 and proceeds to step 117.
