Description

  The present invention relates to a closing operation warning display device for an opening / closing body such as a vehicle door.

  For example, vehicles such as passenger cars are provided with opening / closing bodies such as doors, windows, and sunroofs. These opening and closing bodies are opened and closed by a driving means such as an electric motor for easy operation, and when closing, the opening and closing body is closed (maintaining the opening and closing body in a completely closed state), so that safety during traveling is achieved. To maintain comfort in the car. And when closing the open / close body, there is a risk of clogging of human bodies such as fingers and foreign objects such as clothing hems, so be careful of passengers with alarm sounds such as buzzers, chimes and synthetic voices. It is common to prompt (see Patent Document 1).

JP-A-11-198648

  According to Patent Document 1, an alarm sound can be generated so that a human body or a foreign object is not sandwiched between the window glass and the window frame when the power window device is closed. However, since the number of open / close bodies and alarm sounds is increasing in recent vehicles, a pinch accident occurs because it is impossible to distinguish whether the alarm sound is for preventing pinching or for which open / close body. There is a case.

  The object of the present invention is to visually indicate which open / close body is closed by optical warning display using light irradiation or light projection, and to prevent the human body and foreign objects from being caught. An object of the present invention is to provide a closing operation warning display device for an opening / closing body that can be realized.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-described problem, a closing operation warning display device for an opening and closing body of the present invention is provided.
An opening / closing body that is driven back and forth between an open position and a closed position by a driving means;
Detection means capable of detecting a state in which the opening / closing body is moving along a predetermined movement route from the open position toward the closed position;
When the opening / closing body is placed in the middle of the movement route and the opening / closing body is in the middle of moving from the open position to the closed position, a warning is displayed to indicate the closing of the opening / closing body by light irradiation or light projection on the movement route. Display means,
An operation control unit for operating the display means based on detection of movement of the opening / closing body from the open position to the closed position by the detection means,
When the opening / closing body is moved from the open position to the closed position by the driving means, the display means executes an optical warning display in the middle of the movement route according to an operation command of the operation control unit. .

  According to such a closing operation warning display device for the opening / closing body, when the opening / closing body (for example, a vehicle door) is moved from the open position to the closed position by the driving means (for example, a stepping motor), the display means is in the middle of the movement route. (For example, a laser light-emitting device) performs optical warning display by light irradiation or light projection. Accordingly, it is possible to specifically tell the danger visually which opening and closing body is closing, and it is possible to prevent the human body and foreign objects from being caught.

  Therefore, it can be suitably applied to a vehicle (particularly a luxury passenger car) that includes a large number of opening / closing bodies such as doors, windows, sunroofs, etc. and emits a large number of warning sounds, but can also be used for an opening / closing body such as an elevator door. The vehicle door can be applied to any of a slide door, a swing door, a hatchback door, a luggage door, and the like. The display means uses a light emitting device such as a laser, LED, lamp, or hologram, and displays a warning indicating that the opening / closing body is closed by light irradiation or light projection onto the moving route.

  Sensors such as limit switches and photoelectric sensors that directly detect the movement of the opening / closing body are used as detection means that can detect the state in which the opening / closing body is moving along the predetermined movement route from the open position to the closed position. Although it may be used, the cost may be reduced by using an electric operation switch (manual switch) for driving the driving means so that the opening / closing body moves from the open position to the closed position.

Specifically, the detection means is arranged on the movement route in order to detect the state in which the opening / closing body moves from the open position to the closed position directly or indirectly via the drive means,
The operation control unit can operate the display unit according to the detection of the movement of the opening / closing body by the detection unit.

  Thus, since the detection means is arranged on the movement route and can detect the movement of the opening / closing body directly or indirectly, the detection means suitable for the operation timing of the display means according to the drive speed of the drive means. The installation position can be set (selected) on the movement route.

  For example, when the opening / closing body is a vehicle slide door, the detection means may be either a sensor that directly detects the movement of the slide door or a sensor that indirectly detects a stepping motor (drive means). Specifically, a sensor that indirectly detects the movement of the sliding door detects the movement of a cable connected to the sliding door and driven by a stepping motor (driving means), or the number of pulses of the stepping motor, the rotation angle, The number of rotations can be detected. These direct detection sensors and indirect detection sensors may be contact type (limit switch or the like) or non-contact type (photoelectric sensor, rotary encoder or the like).

Alternatively, the detection means detects the drive time of the drive means when the opening / closing body moves from the open position to the closed position,
The operation control unit can operate the display unit according to detection of the drive time of the drive unit by the detection unit.

  In this way, the detection means detects the drive time (for example, the number of pulses) of the drive means (for example, the stepping motor) and determines the moving distance of the opening / closing body (for example, the vehicle sliding door), so that the display means (for example, the laser light emitting device) The operation timing can be easily adjusted according to the drive time of the drive means.

In addition, the opening / closing body is arranged at the boundary between the room and the outdoors,
The room and the outdoor are equipped with monitoring means for monitoring the presence or absence of a person,
When none of the monitoring means captures the presence of a person, the operation control unit can stop the operation of the display means.

  In this way, if the monitoring means confirms that no person is present inside or outside the opening / closing body, the warning message for the closing operation by the display means is not made, so energy saving can be achieved. For example, in an ECU (Electronic Control Unit) of a vehicle, when an occupant sensor is arranged for adjusting the interior environment of the vehicle and a monitoring camera is arranged for safety confirmation of the surroundings (outside the vehicle), they are used as monitoring means. be able to.

Furthermore, the operation control unit enables electrical connection with a two-way portable device,
The warning display mode of the display means may be changeable from the bidirectional portable device via the operation control unit.

  As described above, the warning display mode of the display means (for example, a laser light emitting device) can be changed using a two-way portable device (for example, a portable personal computer), thereby setting (customizing) the content of the warning display by the user. be able to.

  Note that the bidirectional portable device is a portable information processing device capable of transmitting and receiving data, and includes a portable personal computer, a portable information terminal, a cellular phone, and the like. In addition, as a warning display mode, a light emission form (characters, symbols, images, etc.), a light emission pattern (lighting, blinking, extinguishing, etc.), a light emission color (red, yellow, etc.), etc. can be changed.

Example 1
Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. FIG. 1 is a schematic explanatory view showing an example of a wagon car provided with a closing operation warning display device according to the present invention. A wagon car 1 (vehicle) shown in FIG. 1 includes a slide door 10 (opening / closing body) that is reciprocally driven by a door drive motor 11 (drive means), and a door sensor 20 (detection means) that detects a closing operation of the slide door 10. A laser light emitting device 30 (display means) for displaying a warning that the slide door 10 is closed and a body ECU 100 (operation control unit) for controlling the operation of the laser light emitting device 30 are provided.

  Specifically, when the door drive motor 11 which is a stepping motor winds up the cable 13 connected to the slide door 10, the slide door 10 linearly moves between the open position and the closed position along the straight rail 12. Reciprocally driven. The door sensor 20 includes a limit switch, and detects that the sliding door 10 moves through a linear movement route from the open position to the closed position by direct contact.

  Further, the laser light emitting device 30 is arranged on a linear movement route, and when the door sensor 20 detects the slide door 10, the laser light is irradiated (or projected) on the movement route, thereby a predetermined display mode (for example, red background). A warning message is displayed in yellow with a flashing “KIKEN” character. Then, when the slide door 10 is moved from the open position to the closed position by the door drive motor 11, the body ECU 100 issues a light emission command to the laser light emitting device 30 according to the detection of the slide door 10 by the door sensor 20 and executes a warning display. Let

  Further, the wagon car 1 is provided with monitoring devices 41 and 42 (monitoring means) for monitoring the presence / absence of persons inside and outside the vehicle with the slide door 10 interposed therebetween. Specifically, an occupant sensor 41 (in-vehicle monitoring device; monitoring means) such as a seat sensor is arranged to detect the presence / absence of an occupant and controls the air conditioner (not shown) and the like to make the in-vehicle environment comfortable. To. On the other hand, a monitoring camera 42 (outside vehicle monitoring device; monitoring means) is arranged for safety confirmation of the surroundings (outside the vehicle), and a warning sound is emitted from the buzzer 2b of the instrument panel 2 to notify the occupant (driver) of the danger. . When these monitoring devices 41 and 42 detect that no person is present inside or outside the slide door 10, the laser light emitting device 30 does not display a warning for closing operation.

  The instrument panel 2 is provided with a door opening / closing switch 2a (electric operation switch) for driving the door drive motor 11 to close or open the slide door 10.

  FIG. 2 is a block diagram schematically showing an electrical configuration of the closing operation warning display device of FIG. The body ECU 100 includes a CPU 101 that is an arithmetic device, a ROM 102 that is a read-only storage device for storing programs, a RAM 103 that is a readable / writable storage device to which work areas and various counters are assigned, and an I / O 104 that is an input / output interface. These are connected to each other via a bus (not shown).

  The body ECU 100 includes a door opening / closing switch 2a disposed on the instrument panel 2, a door sensor 20 disposed on a moving route from the open position of the slide door 10 to the closed position, an occupant sensor 41 disposed inside the vehicle, and an exterior of the vehicle ECU 100. Signals from the arranged monitoring cameras 42 are respectively input.

  The body ECU 100 is connected to a portable PC (personal computer) 200 (bidirectional portable machine) so that signals can be input and output with each other. The portable PC 200 includes a CPU 201 that is an arithmetic device, a ROM 202 that is a read-only storage device for storing programs, a RAM 203 that is a readable / writable storage device to which work areas and various counters are assigned, and an I / O 204 that is an input / output interface. Are connected to each other via a bus (not shown).

  The body ECU 100 opens and closes the slide door 10 by driving the door drive motor 11 in response to an operation input of the door opening / closing switch 2a. Further, the body ECU 100 operates (emits light) the laser light emitting device 30 according to the detection of the slide door 10 by the door sensor 20, and also activates (sounds) the buzzer 2b. Note that when both the occupant sensor 41 and the monitoring camera 42 detect the absence of a person, the laser light emitting device 30 and the buzzer 2b do not operate.

  Next, the control of the body ECU 100 will be described according to the flowchart of the closing operation warning process shown in FIG.

  First, the body ECU 100 determines whether or not the door opening / closing switch 2a is closed (S1). When the door opening / closing switch 2a is closed (S1: YES), the occupant sensor 41 and the monitoring camera 42 are operated. In either case, it is determined whether or not the presence of a person is detected (S2). If at least one of them detects the presence of a person (S2: NO), the door drive motor 11 (slide door 10) is closed (S3). Next, the body ECU 100 determines whether or not the door sensor 20 contacts the slide door 10 and is turned on (S4). If the door sensor 20 is on (S4: YES), the body light emitting device 30 is activated. The warning is displayed and the buzzer 2b is operated to emit a warning sound (S5). The operation of the laser light emitting device 30 and the buzzer 2b continues as long as the door drive motor 11 continues to close (S6: NO), and when the door drive motor 11 stops (that is, the slide door 10 completes closing) (S6: YES). ) The operations of the laser light emitting device 30 and the buzzer 2b are stopped (S7), and the closing operation warning process is ended.

  If the door sensor 20 is OFF (S4: NO), the closing operation warning process is terminated as it is, so that the laser light emitting device 30 and the buzzer 2b do not operate. When the door opening / closing switch 2a is not closed (S1: NO), and when both the occupant sensor 41 and the surveillance camera 42 detect the absence of a person (S2: YES), the closing operation warning process is immediately performed. Therefore, the laser light emitting device 30 and the buzzer 2b do not operate.

  Thus, when the sliding door 10 is moved from the open position to the closed position by the door drive motor 11, the laser light emitting device 30 performs an optical warning display by light irradiation or light projection in the middle of the moving route. Thus, it is possible to specifically tell the danger visually that the slide door 10 is closed, and it is possible to prevent the human body and foreign objects from being caught.

  Further, since the door sensor 20 can directly detect the movement of the slide door 10, the installation position of the door sensor 20 suitable for the operation timing of the laser light emitting device 30 is set on the movement route according to the drive speed of the door drive motor 11. Can be set (selected). Furthermore, when the occupant sensor 41 and the monitoring camera 42 both detect the absence of a person, the warning message for the closing operation by the laser light emitting device 30 is not displayed, so that energy saving can be achieved.

  In addition, since the warning display mode (for example, the light emission form, the light emission pattern, and the light emission color) of the laser light emitting device 30 can be changed using the portable PC 200, the content of the warning display can be set (customized) by the user.

(Modification)
As shown in FIG. 1, instead of the door sensor 20 that directly detects the movement of the slide door 10, a cable sensor 21 (limit switch; detecting means) that detects the movement of the cable 13 is provided, and the movement of the slide door 10 is driven by the door. It can be detected indirectly via the motor 11. Similarly, as shown in FIG. 1, instead of the door sensor 20 that directly detects the movement of the slide door 10, a rotary encoder 22 (detection means) that detects the number of pulses (or rotation angle and number of rotations) of the door drive motor 11 is provided. The movement of the slide door 10 can be indirectly detected via the door drive motor 11.

(Example 2)
FIG. 4 is a flowchart showing another example of the closing operation warning process. In this embodiment, the door sensor 20 is omitted in FIG. 1 (Embodiment 1). Further, in the flowchart of FIG. 4, instead of determining whether or not the door sensor 20 is in contact with the slide door 10 (S4 in FIG. 3), the door drive motor 11 is closed (that is, the door drive motor opening / closing switch 2a). (S4 ′) is determined whether or not a predetermined time (for example, 1 second) has elapsed since the closing operation.

  In this embodiment, the drive time (for example, the number of pulses) of the door drive motor 11 is detected to determine the moving distance of the slide door 10, so that the operation timing of the laser light emitting device 30 can be easily set according to the drive time of the door drive motor 11. Can be adjusted.

  In the above embodiment, only the case where the closing operation warning display device is mounted on a wagon car has been described, but it may be mounted on an elevator door or the like.
