2. Description of the Related Art Negligible or unforeseen accidents occur when driving a car, and they often jump into a pond or the sea. Because of the unexpected itself, the drivers and occupants are in a hurry and panic when conscious. While struggling in a sinking car, the doors could not be opened by water pressure, and the windows of the doors were inoperable because they were electrically driven (power windows), making it impossible to escape. For this reason, a tool for breaking glass has been provided in the vehicle interior.

[0003] However, if the consciousness is lost, of course, unless the consciousness is taken, it is necessary to take appropriate measures such as keeping the cabin in a narrow cabin and calmly moving the seat backwards. It is impossible to do. In addition, the rescuer has to start by breaking the glass first, making rescue work difficult. I couldn't do it smoothly.

[0004]

Another object of the present invention is to provide a vehicle safety control method and a safety control device that allow a rescue operation by another person to be performed smoothly.

[0005] A vehicle safety control method for this purpose is a vehicle safety control method having an electric opening / closing device for opening and closing a vehicle compartment, wherein the vehicle flood control detects that the vehicle is immersed in a predetermined amount of water. The opening / closing device is driven to open based on the detection of a sensor or an impact sensor that detects that an impact of a predetermined strength has been applied to the vehicle.

[0006] The vehicle may be provided with an airbag which is inflated by driving of the injection means for injecting gas, and the injection means may be driven based on detection of the water immersion sensor or the impact sensor.

The vehicle safety control device is a vehicle safety control device having an electric opening / closing device for opening / closing a vehicle compartment, and detects that the vehicle has been immersed in a predetermined amount of water in the vehicle. A flood sensor or an impact sensor for detecting that a shock of a predetermined strength is applied to the vehicle is mounted, and drive control is performed to open the opening / closing device based on a detection signal from the flood sensor or the impact sensor. A control means is provided.

The vehicle may be equipped with an airbag which is inflated by driving of a gas injecting device, and the injecting device may be driven based on detection of the water immersion sensor or the impact sensor. .

Further, the vehicle is equipped with an airbag which is inflated by the driving of the injecting means for injecting a gas and maintains the inflated state, and the injecting means is used to determine that the vehicle has been immersed in a predetermined amount of water. It is a safety control method of a vehicle driven based on detection of a waterlogging sensor for detecting or an impact sensor for detecting that an impact of a predetermined strength is applied to the vehicle.

In addition, the vehicle is equipped with an airbag which is inflated by the driving of an injection means for injecting gas and maintains the inflated state, and the vehicle is provided with an inundation for detecting that the vehicle has been soaked in a predetermined amount of water. A sensor or a shock sensor for detecting that vibration of a predetermined intensity is applied to the vehicle is mounted, and control means for driving and controlling the injection means is provided based on a detection signal from the immersion sensor or the shock sensor. It is a safety control device for a vehicle.

[0011]

According to the first to fourth aspects of the present invention, when the immersion sensor or the impact sensor detects the danger of the vehicle, the electric opening / closing device for opening / closing the vehicle compartment is controlled by the control means. It is automatically opened while operable by the drive control of.

For this reason, when jumping into a pond or the sea, it is possible to escape easily through an open window. This escape does not require any measures such as breaking glass, so it can be done without delay. In addition, since water enters into the sinking vehicle through the open window, even if the occupant loses consciousness, there is a high possibility that the occupant will return consciousness more quickly, and escape is possible without falling into a panic state.

[0013] The same applies to the rescuer, so that the occupant can be pulled out through a window or the like, and the rescue operation can be performed smoothly. Further, since the windows and the like are open, when the vehicle is pulled up, the vehicle may be locked from the windows or the like, and there is no difficulty.

When an airbag that expands based on the detection of a water immersion sensor or an impact sensor is provided, the speed at which the vehicle sinks can be suppressed. In particular, the effect is high when provided in a heavy engine room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a control circuit of a safety control device of an automobile 1. As shown in FIG. 2, in an automobile 1 having a sunroof 3 and a door glass 2 that opens and closes electrically, the door glass 2 that opens and closes a vehicle compartment Then, the sunroof 3 is opened based on detection of a predetermined situation.

The immersion sensor 4 detects that the vehicle 1 has been immersed in water by a predetermined amount, and may be constituted by an appropriate device for energizing when wet. For example, it may be constituted by simple means such as two electrodes arranged at appropriate intervals, and may be mounted at an appropriate position on the automobile 1 so as to correspond to the level of inundation to be detected. In order to prevent malfunctions due to running in rainy weather or intrusion into water pools, a cover for blocking unnecessary water is attached, or the attachment position is devised.
In this embodiment, it is mounted in two places: an engine room in a front body of a vehicle body and a luggage compartment in a rear body. By attaching to two places before and after,
Appropriate inundation detection can be performed whether jumping in from the front or from behind.

The immersion sensor 4 may be configured as shown in FIG. 3, for example. That is, this immersion sensor 4
In the bottom plate 6 of the cylindrical outer case 5, an intrusion hole 7 for water to enter is formed, and the top plate 8 has two electrodes 9, 10.
, And an air vent hole 11. Inside the outer case 5, a float member 12 having a conductive plate 12a on its upper surface is housed. That is, the water that has entered the outer case 5 through the intrusion hole 7 pushes up the float member 12 and the conductive plate 12a of the float member 12 comes into contact with the electrodes 9 and 10 to conduct electricity, and detection is performed. The height of the lower surface of the float member 12 when the electrodes 9, 10 and the conductive plate 12a are in contact with each other is the immersion detection level, and the height is set to a desired position. In order to prevent the float member 12 from moving up and down due to the vibration caused by the traveling of the automobile 1 and malfunctioning,
An appropriate weight may be attached to the lower surface of the float member 12. In addition, in order to prevent a malfunction such as when the automobile 1 is tilted during running, the outer case 5 is mounted on the vehicle body.
May be suspended via a universal joint or the like, and may be freely tilted, for example, by about 30 degrees.

The vibration sensor 13 may be composed of, for example, a well-known acceleration sensor, and is set at a level which cannot be detected by a sudden braking or the like which is normally possible. This vibration sensor 1
The reference numeral 3 may be attached to each part of the automobile 1, for example, in an instrument panel as shown in the figure, or in a part having the least vibration such as a central part of a chassis.

The impact sensor 13 may be configured as shown in FIG. 4, for example. That is, the impact sensor 13
Has two electrodes 15 at one end in a cylindrical outer case 14.
A piston-like slider 17 that slides toward the electrodes 15, 16 is provided. The tip of the slider 17 is a conductive plate 17a, and a spring 18 for urging the conductive plate 17a in a direction away from the electrode is interposed. When the receiving surface 17b at the rear end of the slider 17 hits the water surface and receives an impact, the slider 17 slides toward the electrodes 15 and 16 against the biasing force of the spring 18, and the conductive plate 17a at the tip of the slider 17 is 15,1
6 and is energized to perform detection. The impact sensor 13 may be mounted at an appropriate position such as near the front and rear bumpers.

The CPU 19 executes a control operation in accordance with a program stored in the ROM 20, and stores necessary control data in the RAM 21.

The power window motor 22 lifts and lowers the door glass 2 to open and close the vehicle compartment. The power window motor 22 is rotated by a switch operation so as to be fully opened in response to an output signal from the CPU 19 in addition to normal forward / reverse rotation.

Similarly, the sunroof motor 23 slides the sunroof 3 to open and close the cabin. The sunroof motor 23 is rotated by a switch operation so as to be fully opened in response to an output signal from the CPU 19 in addition to the normal forward / reverse rotation.

The gas injection solenoid valve 24 is for inflating an airbag 25 as shown in FIG. 5 by injecting a gas such as carbon dioxide, and is attached to a high-pressure cylinder 26. The airbag 20 serves as a float and suppresses sinking of the vehicle 1 in water. In this embodiment, the airbag 25 is housed in a lining (head lining 28) of a suspended ceiling below a roof panel 27. When the airbag 25 is attached to the lower surface of the head lining 28, the airbag 25 may be formed large. However, as shown in FIG. When the airbag 25 is housed inside the head lining 28 as shown in the figure, the head lining 28 forms a cut so that the airbag 25 is torn when the airbag 25 is inflated, or extends when the airbag 25 is inflated. Or made of stretchy fabric.

The airbag 25 is connected to a high-pressure cylinder 26 via a high-pressure hose 30. The gas injection solenoid valve 24 is driven by an output signal from the CPU 19 to open the high-pressure cylinder 26 and inflate the airbag 25. A check valve 31 is interposed between the airbag 25 and the high-pressure hose 30 so that the inflated airbag 25 is not contracted.

The airbag 25 is located at an appropriate position in addition to the ceiling.
For example, it may be installed in the lower part of the vehicle body and in the heavy engine room. When installed in the engine room, the effect of suppressing the sinking of the automobile 1 is high.

The control operation will be described below. When the vehicle 1 jumps into the sea, it hits the water surface and the vibration sensor 13
Outputs a detection signal to the CPU 19, and the CPU 19
21 is read out. Since the detection signal of the immersion sensor 4 is not stored, the detection signal of the vibration sensor 13 is set to R
Store it in AM21. Subsequently, when water enters, the immersion sensor 4 outputs a detection signal to the CPU 19,
19 reads out the storage in the RAM 21. Then, since the detection signal from the vibration sensor 13 is stored, the power window motor 22 and the sunroof motor 23 are driven to rotate in the opening direction, and the gas injection solenoid valve 24 is opened. Then, all the door glasses 2 and the sunroof 3 of the vehicle 1 are opened, and the airbag 25 is inflated, thereby suppressing sinking of the vehicle 1 underwater.

For this reason, when jumping into a pond or the sea, the occupant can easily escape by himself through the open door glass 2 and the sunroof 3. This escape does not require any measures such as breaking glass, so it can be done without delay. In addition, since water enters into the sinking automobile 1 through an open window, even if the occupant loses consciousness, there is a high possibility that the occupant will return consciousness more quickly, and it is possible to escape without falling into a panic state. .

The same applies to the rescuer, so that the occupant can be pulled out through the window and the sunroof, and the rescue operation can be performed smoothly. Further, since the windows and the like are open, when the vehicle is pulled up, the vehicle may be locked from the windows or the like, and there is no difficulty.

In particular, since the control means is configured to open the switchgear by the logical product of the immersion sensor and the impact sensor having different properties, it is possible to accurately detect a specific state of jumping into the water, and to malfunction. Accidents can be dealt with reliably.

Incidentally, a safety measure may be taken only by detecting one of the water immersion sensor 4 and the vibration sensor 13. For example, in order to increase the time required for the car 1 to sink, an airbag 25 is mounted on the lower part of the car 1, for example, as shown in FIG.
It may be made to swell immediately before or immediately after landing, that is, immediately upon impact.

An airbag 25 is incorporated in a door trim 34 attached to the inner surface of the inner panel 33 of the door 32, and a high-pressure cylinder 26 in which the airbag 25 is filled with gas and a gas is supplied from the high-pressure cylinder 26 as described above. A gas injection solenoid valve 19 for injecting, a high-pressure hose 30 for sending gas, and a check valve 31 for preventing return of the gas injected into the airbag 25 are connected. The cover material 35 of the door trim 34 is made of a material that is cut or stretched when the airbag 25 is inflated so as not to prevent the airbag 25 from inflating. Although the airbag 25 may be mounted anywhere, it is advantageous to mount the airbag 25 on the lower side of the automobile 1 as much as possible to suppress sinking.

In the vehicle 1 thus configured, the driving is controlled by the control means including the CPU 19, the ROM 20, and the RAM 21 as shown in FIG. That is, when the automobile 1 jumps into the sea, the vibration sensor 13 outputs a detection signal to the CPU 19 by hitting the impact or the water surface at the time of the jump,
The gas injection solenoid valve 24 is opened based on this output.
Then, the airbag 25 is inflated and the sinking of the vehicle under water can be suppressed.
