Description

  The present invention relates to a door window forgetting prevention device, and more particularly to a technique for warning a vehicle driver that a door window provided on a door of a vehicle can be opened and closed.

  In recent years, a switch that can open and close a door window is provided on a door of a vehicle, and a power window that can be easily opened and closed by pressing the switch has been adopted. This power window has a switch for the door window other than the driver's seat so that the driver can open the door window other than the driver's seat while the driver is in the driver's seat even when the driver is the only driver. Generally, it is also provided at a door near the driver's seat.

However, because the driver can open and close while driving the door windows of all doors, the driver forgets to open the door windows (especially the door window of the rear seat) and forgets to close the door windows due to lack of confirmation. There is a problem.
As described above, forgetting to close the door window may cause the interior of the vehicle to get wet with rain or malfunction of electrical components mounted on the vehicle if it rains with the door window open. . Also, depending on the degree of opening of the door window, a locked door can be unlocked by a third party from the opened portion, which may cause vandalism and theft of the vehicle, which is not preferable. .

In this case, for example, it is conceivable that the door window is automatically closed simultaneously with stopping the engine. Thereby, even when the driver forgets to close the door window, the door window can be reliably closed.
On the other hand, when the engine is stopped while the door window is open, a power window forgetting to close device has been developed to generate a warning sound when the driver's door is opened. (Patent Document 1)
JP-A-10-259591

However, as described above, it is not preferable to automatically close the door window at the same time as stopping the engine because the door window intentionally opened by the driver for ventilation is also closed.
Moreover, in the technique disclosed in Patent Document 1, it is impossible to determine whether the door window is opened intentionally by the driver or forgetting to close the door window. If the driver has a high frequency of opening the door window, the warning sound is routine, and the driver closes the door window without worrying about the warning sound even if the door window is forgotten to close. There is a problem of forgetting.

  The present invention has been made in view of such problems, and the object of the present invention is to determine whether the door window in the open state is due to the driver forgetting to close or whether the door window is intentionally opened. An object of the present invention is to provide a door window forgetting prevention device that can reliably warn the driver that the door window has been forgotten to be closed.

  In order to achieve the above object, the door window forgetting prevention device of the present invention includes a drive device stop detection means for detecting a stop of a drive device for running a vehicle, and a door window provided on the door of the vehicle so as to be opened and closed. The door window opening degree detecting means for detecting the opening and the degree of opening thereof and the driving apparatus stop detecting means detect the stop of the driving device, and if the door window opening degree detecting means detects the opening of the door window, a warning is issued. Warning means, wherein the warning means changes the content of the warning according to the door window opening degree detected by the door window opening degree detection means, and issues a warning of the changed content. .

  As a result, even if the driver forgets to visually check the open state of the door window, or there are many loads loaded on the vehicle and the view is blocked by the load, it is difficult to see the open state of the door window. Because the driver can sensuously recognize the degree of opening of the door window according to the content of the warning, the driver can recognize the degree of opening of the door window without looking at the door window. Is done.

As another aspect, it is preferable that the warning means sets and stores the opening degree of one or a plurality of door windows in advance as a specified value, changes the content of the warning based on the specified value, and issues a warning.
As a result, the contents of the warning can be changed for each preset value including the preset value arbitrarily set by the driver, so the driver is warned accurately about the degree of door window opening. Is possible.

As another aspect, it is preferable that one of the specified values is a door window opening degree preset for ventilation.
As a result, the content of the warning is changed depending on whether the height of the upper end of the door window is higher or lower than the preset height for ventilation, so that the degree of opening is recognized by the driver. The driver may ignore the warning, and if the driver accidentally opens the door window, the driver will notice that the door window has been forgotten to be closed. It is possible to deal with closing the door window.

As another aspect, it is preferable that the vehicle has rain detection means for detecting rain, and the warning means further changes the content of the warning and issues a warning when the rain detection means detects the rain.
As a result, the door window is not normally left open in the rain, so it can be determined that the door window in the open state is less likely to be ventilated and the door window is more likely to be forgotten to be closed. It is possible to reliably warn the driver by changing the content of the warning about forgetting to close.

In another aspect, the vehicle has an outside air temperature detecting means for detecting the temperature of the outside air of the vehicle. It is preferable to make further changes and issue warnings.
This makes it possible to determine whether the opened door window is intentional for lowering the temperature inside the vehicle or forgetting to close the door window. It is possible to warn the driver.

As another aspect, it has a lock detecting means for detecting the locked state of the door, and the warning means changes the content of the warning when the lock detecting means detects that the door is locked. It is preferable to issue a warning.
Thus, even when the driver is highly likely to leave the vehicle for a long time, it is possible to warn the driver so that the door window does not open for a long time.

  As another aspect, there is an occupant detection means for detecting the presence of an occupant inside the vehicle, and the warning means emits a warning toward the inside of the vehicle and a warning toward the outside of the vehicle. If the occupant detection means detects the presence of an occupant inside the vehicle, the warning device issues a warning, and the occupant detection means does not detect that the occupant is inside the vehicle. It is preferable to issue a warning by an outside alarm device.

As a result, a warning can be issued to those who have a driver or occupant, and a warning can be issued to the inside of the vehicle even if the occupant is outside the vehicle, or the vehicle can be used regardless of whether the occupant is inside the vehicle. It is possible to avoid issuing unnecessary warnings such as issuing warnings outside the screen.
As another aspect, the vehicle has position information detection means for detecting the position information of the vehicle, the warning means stores the position information designated in advance, and the position information of the vehicle detected by the position information detection means is stored in advance. When the position information matches the specified position information, it is preferable not to issue a warning or to change the content of the warning and issue a warning.

As a result, it is possible to identify places where there is no problem with opening the door window, such as places with roofs, or where it is necessary to pay attention to forgetting to close the door window, and it is possible to provide necessary and sufficient warnings. Is done.
As another aspect, it is preferable that the warning means emits a warning sound as a warning and changes the content of the warning by changing the content of the warning sound.

  As a result, even when the driver or the occupant turns his back to the vehicle, the warning can be recognized by sound.

  According to the door window closing and forgetting prevention device of the present invention, when the driver forgets to visually confirm the open state of the door window, or when there is a lot of luggage loaded on the vehicle, the view is blocked by the luggage and the door window Even if it is difficult to visually recognize the condition, the driver can sensuously recognize the degree of opening of the door window by the content of the warning. The degree of opening can be recognized.

  Therefore, for example, since the warning contents differ depending on whether the height of the upper end of the door window is higher or lower than the preset height for ventilation, the driver recognizes the degree of opening. The driver may ignore the warning, and if the driver accidentally opens the door window, the driver notices that the door window has been forgotten to close. The door window can be surely closed.

  In this way, it is determined whether the door window in the open state is due to the driver forgetting to close the door or intentionally opened, and the driver is surely warned that the door window has been forgotten to close. Can do.

1 is a schematic configuration diagram of a vehicle. It is a block diagram around the driver's seat in the vehicle. It is a schematic block diagram of the power window apparatus of a door. It is a block diagram of the door window closing forgetting prevention device according to the present invention. It is a flowchart which shows the control procedure of the door window closing forgetting prevention apparatus which concerns on this invention which ECU performs.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram of a vehicle 1.
The vehicle 1 is a passenger car equipped with an engine (drive device) 2. A plurality of doors 4 provided with door windows 3 are arranged on the side of the vehicle 1.
Referring to FIG. 2, a configuration diagram around the driver's seat in the vehicle interior 10 is shown. Various operation switches and various instruments are arranged on the instrument panel 11 in the vehicle interior 10, and are located near the steering wheel 12. Thus, an ignition switch (driving device stop detecting means) 14 for starting and stopping the engine 2 is provided. A seat 16 is provided behind the steering wheel 12 in the vehicle interior 10, and a door window switch for opening and closing the door window 3 is located near the center of the door 4 in the vertical direction on the door 4 next to the seat 16. (Switch) 20 is provided.

  A room mirror 24 is installed on the vehicle interior 10 side in the upper center portion of the windshield 22, and the surface of the windshield 22 on the vehicle interior 10 side is located so as to be hidden by the room mirror 24 when viewed from the driver. A GPS (position information detecting means) 26 is installed. A display panel 27 is provided at a position corresponding to the center in the left-right direction of the inside 10 of the instrument panel 11. The position information from the GPS 26 is displayed on the display panel 27 as, for example, a position on a map.

Further, a wiper (rain detection unit) 28 is provided outside the windshield 22 so as to remove raindrops attached to the windshield 22 when it rains. The wiper 28 is configured to be operated by an electric motor (not shown) when the driver operates an operation switch, for example, in rainy weather.
The ignition switch 14 is, for example, a push button type switch. When the driver presses the ignition switch 14 when the engine 2 is stopped, the engine 2 starts. When the engine 2 is operated, when the ignition switch 14 is pressed, the engine 2 is turned off. Can be stopped. The ignition switch 14 may be configured to start and stop the engine 2 by inserting a key, as long as it can start and stop the engine 2 in accordance with the driver's intention even if it is not a push button type. May be.

The seat 16 is configured to be able to detect whether or not the driver is sitting. Specifically, for example, a mass measuring device (occupant detection means) is provided inside the seat 16, and when the driver sits down, the mass is measured by the mass measuring device. 16 can be determined to be sitting.
Referring to FIG. 3, the internal structure of the door 4 is shown. The door 4 is equipped with a power window device 30 for raising and lowering the door window 3. The power window device 30 includes a rotating motor 32 and a regulator 34 that converts the rotational motion of the motor 32 into the vertical motion of the door window 3. By operating the door window switch 20 and operating the motor 32, It is possible to raise and lower the door window 3 and thus open and close the door window 3.

In addition, for example, an encoder (door window opening degree detecting means) 36 that records the number of rotations of the motor 32 is attached to the motor 32 so that the height (opening degree) of the upper end of the door window 3 can be detected. . The encoder 36 is electrically connected to an ECU 40 described later.
As shown in FIG. 1, the vehicle 1 is provided with a door lock system (door lock device) 38 that locks the door 4. In addition, a temperature sensor (vehicle outside temperature detecting means) 39 is disposed, for example, at the front portion of the vehicle 1 so that the outside air temperature can be measured. The position of the temperature sensor is not necessarily the front portion of the vehicle 1 as long as the temperature outside the vehicle 1 can be measured.

  The door lock system 38 is configured to be remotely operable, for example. That is, the door lock system 38 includes a portable transmitter that emits radio waves and a receiver that receives the radio waves emitted by the transmitter. Accordingly, when the driver sends a signal for locking / unlocking the door 4 using the transmitter, the receiver can receive the radio wave emitted from the transmitter, and the door 4 can be locked / unlocked electrically. Locking / unlocking of the door 4 is not limited to this, and the door 4 may be locked / unlocked by providing a key hole in the door 4 and inserting a key into the door 4 and turning it.

The ECU 40 is a control device for performing overall control of the vehicle 1 including operation control of the engine 2, and includes an input / output device, a storage device (ROM, RAM, nonvolatile RAM, etc.), and a central processing unit (CPU). Etc. are configured.
Referring to FIG. 4, a connection configuration of the ECU 40 relating to the control of the door window forgetting to prevent closing device according to the present invention is shown in a block diagram.

  As shown in the figure, the ignition switch 14, the door lock system 38, the seat 16 mass measuring instrument, the encoder 36, the wiper 28, the temperature sensor 39, and the GPS 26 are electrically connected to the input side of the ECU 40. Thus, the ECU 40 detects whether the engine 2 is operating based on a signal from the ignition switch 14 and detects whether the door 4 is locked based on a signal from the door lock system 38. Whether the driver is sitting on the seat is detected based on the signal from the mass measuring instrument of the seat 16, and the height of the upper end of the door window 3 is detected based on the signal from the encoder 36. The use of the wiper 28 is detected based on the operation signal, the temperature outside the vehicle 1 is detected based on the signal from the temperature sensor 39, and the position information of the vehicle 1 is detected based on the signal from the GPS 26.

  Further, on the output side of the ECU 40, an in-vehicle speaker (in-vehicle warning device) 50 provided so as to emit a warning sound toward the inside of the vehicle 10 and a vehicle exterior provided so as to emit a warning sound toward the outside of the vehicle 1 are provided. A speaker (outside vehicle warning device) 52 is electrically connected. Thereby, in the ECU 40, a warning sound is emitted from either the in-vehicle speaker 50 or the out-of-vehicle speaker 52 in accordance with each detection result (warning means). Specifically, the ECU 40 is variably set with the contents of the warning sound corresponding to each of the detection results, the contents of the warning sound are determined according to the respective detection results, and the warning sound of the determined contents is transmitted to the in-vehicle speaker. 50 or the speaker 52 outside the vehicle. As the contents of the warning sound, for example, tone color, tone quality, tone range, scale, volume, sound pattern, etc. are raised, and the contents of the warning sound are appropriately selected according to each detection result.

Next, the effect | action of this embodiment is demonstrated using FIG.
Referring to FIG. 5, a routine showing the control procedure of the door window closing forgetting prevention device according to the present invention, which is executed by the ECU 40, is shown in a flowchart, and will be described below with reference to the flowchart.
When the engine 2 is started by turning on the ignition switch 14, this routine is started.

  In step S10, for example, a period in which the wiper 28 is used in the period until the ignition switch 14 is turned off is stored, and it is determined whether or not it is raining based on the stored information. In the case where the vehicle 1 includes a so-called raindrop sensor that detects the amount of rain passing through the windshield 22 and detects the amount of raindrops attached to the windshield 22 to determine whether or not the rainfall is zero. Instead of using the wiper 28, the raindrop sensor may be used to determine whether or not it is raining.

In step S12, it is determined whether or not the ignition switch 14 is turned off. If it is determined that the ignition switch 14 is turned off and the engine 2 is stopped, the process proceeds to step S14.
In step S14, the open / closed state of the door window 3 is determined based on the information from the encoder 36. When it is determined that the door window 3 is closed, the routine ends. On the other hand, if it is determined that the door window 3 is in an open state based on the information from the encoder 36, the process proceeds to step S16, where there is a place where the current location measured by the GPS 26 is set in advance, for example, a roof designated by the driver. If it is a parking lot, the routine ends.

If it is determined in step S16 that the current location is not the set location, the process proceeds to step S18, and a warning sound is emitted from the in-vehicle speaker 50 toward the in-vehicle 10 for a predetermined time. Note that the warning sound may be a sound, and it is desirable that the warning sound be distinguishable from other announcements such as an announcement forgetting to remove the ETC card.
In step S20, it is determined whether or not the door 4 is locked by the door lock system 38. If it is determined that the door 4 is locked, the process proceeds to step S22.

In step S22, the open / closed state of the door window 3 is determined again based on the information from the encoder 36. If it is determined that the door window 3 is closed, the routine ends. On the other hand, if it is determined in step S22 that the door window 3 is in the open state, the process proceeds to step S24.
In step S <b> 24, it is determined whether or not the driver is sitting on the seat 16 based on information from the mass measuring device of the seat 16. If it is determined that the driver is sitting on the seat 16, the process returns to step S <b> 18 to continue sounding the in-vehicle warning sound. On the other hand, if it is determined that the driver is not sitting on the seat 16, the process proceeds to step S <b> 26. That is, in step S24, it is determined whether the driver is in the vehicle 10 or outside the vehicle 1. If the driver is in the vehicle 10, a warning sound is emitted toward the vehicle 10 in step S18. If the vehicle is outside the vehicle 1, the process proceeds to step S26 and subsequent steps.

  In step S26, it is determined whether or not the rainfall amount is 0 based on the rainy weather information stored in step S10. If it is determined in step S26 that the amount of rainfall is> 0, that is, it is raining, the process proceeds to step S41, and the first outside warning sound is generated by the outside speaker 52. On the other hand, if it is determined in step S26 that the rainfall amount = 0, that is, it is determined that it is not raining, the process proceeds to step S28. Note that the determination may not be made based on whether or not the rainfall amount is 0, but may be determined based on a rainfall amount that does not wet the interior 10 even if the door window is forgotten to close, such as drizzle.

  In step S28, it is determined from the information from the temperature sensor 39 whether the outside air temperature is so high that the door window 3 needs to be opened and ventilated. If it is determined in step S28 that the temperature outside the vehicle 1 is equal to or lower than a predetermined value, that is, the outside air temperature that does not need to be ventilated, the driver opens the door window 3 that is opened to ventilate the interior 10 of the vehicle. It can be determined that the situation is not intentionally open. In this case, the process proceeds to step S42, and the second outside warning sound is generated by the outside speaker 52.

On the other hand, if it is determined in step S28 that the temperature outside the vehicle 1 is higher than a predetermined value, that is, the outside air temperature that needs to be ventilated, the driver deliberately drives the door window 3 to ventilate the interior 10 of the vehicle. Is determined to be open, and the process proceeds to step S31.
In step S31 and step S32, it is determined whether or not the height of the upper end of the door window 3 detected by the encoder 36 is lower than the predetermined value based on a predetermined value of the height of the upper end of the door window 3. If it is determined that the height of the upper end of the door window 3 is equal to or greater than each specified value, a vehicle outside warning sound set in advance corresponding to the specified value is generated. Specifically, as the specified value of the height of the upper end of the door window 3, a first specified value and a second specified value are set here, and the second specified value <the first specified value.
In step S31, it is determined whether or not the upper end of the door window 3 is lower than the first specified value. The first specified value is, for example, a height corresponding to the degree of opening for ventilation. If it is determined that the upper end of the door window 3 is greater than or equal to the first specified value, a third outside warning is issued from the outside speaker 52 for a predetermined time in step S43, and the upper end of the door window 3 is lower than the first specified value. If it is determined, the process proceeds to step S32.

  In step S32, it is determined whether or not the upper end of the door window 3 is lower than a second specified value. The second specified value is a height corresponding to a height at which it is difficult for a vehicle to be tampered with, for example, a degree of opening that does not allow a person's arm to pass through. If it is determined that the upper end of the door window 3 is greater than or equal to the second prescribed value, a fourth outside warning is issued from the outside speaker 52 for a predetermined time in step S44, and the upper end of the door window 3 is lower than the second prescribed value. If it is determined, the process proceeds to step S45, and the fifth outside-vehicle warning is issued from the outside-vehicle speaker 52 for a predetermined time. For example, when a visor is provided at the upper end portion of the door 4 so as to prevent rain from entering, the first specified value and the second specified value may be set as appropriate based on the height of the lower end of the visor. Good.

  Also, here, two types of specified values are set and different outside warning sounds are generated. However, the present invention is not limited to this, and three or more types of specified values may be set. It may be possible to variably set with the operation switch of the ment panel 11 so that the driver can arbitrarily set or adjust the specified value. Alternatively, the outside warning sound may be changed steplessly according to the height of the upper end of the door window 3, and in this case, for example, the lower the upper end of the door window 3, the louder the outside warning sound becomes. Or change the tone.

When a vehicle outside warning sound is emitted from the vehicle outside speaker 52 for a predetermined time in steps S41 to S45, this routine ends.
As described above, in the door window closing forgetting prevention device according to the present invention, when the driver operates the ignition switch 14 and stops the engine 2, the door window 3 is in the open state. It is possible to change the content of the warning sound according to the degree of opening of 3.

  Therefore, when the driver forgets to visually confirm the open state of the door window 3 or when there is a lot of luggage loaded on the vehicle 1 and the field of view is blocked by the luggage, it is difficult to visually recognize the state of the door window 3. However, the driver can recognize the degree of opening of the door window 3 sensuously, particularly audibly by the warning sound, and the driver can recognize the degree of opening of the door window 3 without viewing.

  Thus, for example, if the driver opens the door window 3 for ventilation or the like and the opening degree is the opening degree recognized by the driver, the driver may ignore the warning. If the door window 3 is mistakenly opened by mistake, it is possible to notice that the door window 3 has been forgotten to be closed by a warning sound, and to deal with it so that the door window 3 can be reliably closed.

That is, by distinguishing the warning sound between the warning sound when the driver opens the door window 3 for daily ventilation and the warning sound when the driver opens the door window 3 by mistake, Since the warning sound that is accidentally opened cannot be heard by the driver, the driver can be made to recognize a truly necessary warning.
Further, in addition to the predetermined value set in advance based on the height of the upper end of the door window 3, the driver can arbitrarily set the specified value and change the warning sound for each specified value. It is also possible to accurately tell the driver the degree of opening.

Further, it is determined whether or not the amount of rainfall is 0 based on information from the rainy weather detection means, and if it is determined to be rainy, the warning sound is changed to emit a warning sound.
Therefore, in general, since the door window 3 is not left open in the rain, it can be determined that the door window 3 in the open state is less likely to be ventilated and the door window 3 is more likely to be forgotten to be closed. It is possible to reliably warn the driver that the door window 3 has been forgotten to be closed by changing the warning sound.

Further, the warning sound is changed according to the temperature outside the vehicle 1 detected by the temperature sensor 39, and the warning sound is emitted.
Therefore, by setting the predetermined value to a temperature at which the interior 10 is likely to be hot enough to require ventilation, the door window 3 that has been opened is intentionally designed to lower the interior 10 temperature, or the door. Since it is possible to determine whether the window 3 has been forgotten to be closed, it is possible to more precisely determine whether the door window 3 has been forgotten to be closed and warn the driver using a more accurate warning sound.

In particular, when the door lock system 38 determines that the door 4 is locked, the warning sound is changed and the warning sound is emitted.
Therefore, even when the driver is highly likely to leave the vehicle 1 for a long time, it is possible to warn the driver that the door window 3 will not be opened for a long time.
Further, when there is an occupant in the vehicle interior 10, a warning sound is emitted toward the vehicle interior 10, and when there is no occupant in the vehicle interior 10, a warning sound is emitted toward the outside of the vehicle 1.

Therefore, a warning sound can be reliably emitted toward a driver or a passenger, and a warning sound can be emitted in the vehicle interior 10 even when the passenger is outside the vehicle 1, or the passenger is in the vehicle interior 10. Nevertheless, it is possible to prevent an unnecessary warning sound from being emitted outside the vehicle 1.
Further, the position information of the vehicle 1 is detected by the GPS 26, and when the vehicle 1 is in a predesignated location, no warning sound is generated or the warning sound is changed and the warning sound is generated.

Therefore, a place where there is no problem even if the door window 3 is opened, such as a place with a roof, can be specified, and a necessary and sufficient warning can be given.
Although the description of the door window closing forgetting prevention device according to the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be changed without departing from the gist of the invention.
For example, the vehicle 1 may not be a car equipped with the engine 2 but may be an electric car equipped with a motor as a driving device, or may be a truck used for transporting cargo without being limited to a passenger car.

In the present embodiment, the series of warnings is performed by the ECU 40 that is the control device of the vehicle 1, but may be performed by a dedicated control device provided to perform the present invention instead of the ECU 40.
In addition to determining whether or not there is an occupant in the vehicle interior 10 using the mass measuring instrument of the seat 16, for example, a thermo camera is installed in the vehicle interior 10 to detect whether or not there is an occupant in the vehicle interior 10 by detecting the body temperature of the occupant. You may make it judge.

  Further, in the present embodiment, in step S16 in FIG. 5, the warning sound is not generated when the vehicle 1 is in a predesignated location, but the warning sound is reduced in addition to not generating the warning sound. You may make it do. On the other hand, if you want to prevent forgetting to close the door window 3 in particular, such as an outdoor parking lot where the vehicle 1 is frequently parked for a long time due to commuting, set the location. However, the warning may be stronger than in other places.

  Further, in this embodiment, the warning is performed by generating an in-vehicle warning sound or an out-of-vehicle warning sound using the in-vehicle speaker 50 or the out-of-vehicle speaker 52, but in addition to generating the warning sound, for example, a room light or door courtesy is used. The vehicle interior warning may be issued, and the vehicle exterior warning may be issued using a turn signal or a headlight.
