2. Description of the Related Art When a dry state of low humidity continues, static electricity tends to be charged on a member to be charged such as an occupant, a vehicle, and the like, and various troubles due to the static electricity occur. For example, when the back is rubbed against the seat during driving of the vehicle, static electricity is charged to the body, clothes, shoes, and the like due to the friction. In addition, when the vehicle travels in fine weather, static electricity is charged to the vehicle due to friction between tires and the ground, friction between the vehicle body and air, and the like. If an occupant or the like touches a door knob or the like of the vehicle in this state, the charged static electricity may be discharged and an unpleasant electric shock may be received.

As a countermeasure for alleviating an occupant's electrostatic shock, there is, for example, a static eliminator disclosed in Japanese Patent Application Laid-Open No. 9-245987. This static eliminator is a so-called vehicle key 30 as shown in FIG. 8, which includes a metal key portion 31 and a static electricity neutralizing portion 32 which is a holding portion fixedly provided to the key portion 31.

[0023]

Embodiments of the present invention will be described below with reference to examples. FIG. 1 is a block diagram showing a first embodiment of the present invention. In this embodiment, an ion generator 8 controlled by an operation controller 7 is provided. Operation control unit 7
A door lock sensor 1 for detecting the locking and unlocking of the driver's door, an external door knob sensor 2 for detecting the operating state of the external door knob 12 of each door 10, and an internal door knob for detecting the operating state of the internal door knob on each door room side. A sensor 3, an ignition sensor 4 for detecting an operation state of the engine, a vehicle speed sensor 5 for detecting a running speed of the vehicle, and a timer 6 are connected. The external door knob sensor 2 and the internal door knob sensor 3 are provided in a plurality corresponding to the driver's door and the other doors, respectively, but only one is shown for simplicity.

The ion generator 8 includes an external door knob portion and a window frame portion of each door to which an occupant may come in contact when getting on and off.
The ionization needle sets 8a, 8b, and 8c are provided in the ignition section, respectively, and a high voltage is applied to these ionization needle sets to generate negative ions and positive ions.

That is, as shown in FIG. 2A, an ionizing needle set 8a is installed inside the door outer panel 10a, and ions released from the ionizing needle are formed on the outer door knob section 11 of the door outer panel. It flows from the communication hole 13 around the external door knob 12. This allows
Ions are supplied around the occupant operating the external door knob 12. Similarly, the window frame 15 is provided so as to supply ions along the rear edge 16a and the lower edge 16b of the window frame 16 near the door knob of the door 10, as shown in FIG. 2B. As for the ignition section 18, as shown in FIG.
An ionization needle set (not shown) is installed so that ions are supplied around 9. In the figure, the circled (-) indicates a negative ion, and the (+) indicates a positive charge charged to the occupant.

The operation control unit 7 controls the ion generator 8 based on the information from the sensors and the time measured by the timer to discharge ions from a predetermined ionization needle set.

Next, control by the operation control unit 7 will be described. FIG. 3 is a flowchart showing the flow of control when the occupant gets on the vehicle. This control starts when the door lock of the driver's seat door is unlocked by, for example, a radio signal. That is, when an unlocked state of the door lock (hereinafter, referred to as an open state) is detected by a signal from the door lock sensor 1 in step 101, it is expected that the door will be opened and the vehicle will be boarded. A command is sent to the generator 8, and the external door knob 1 of each door is
Ion emission from the ionization needle sets 8a and 8b of the window frame portion 1 and 1 is started. At the same time, the timer T0 of the timer 6 is reset.

In step 103, it is checked whether or not the external door knob of the driver's seat door has been operated based on a signal from the external door knob sensor 2. If the external door knob has been operated, the process proceeds to step 104; otherwise, the process proceeds to step 108. When the external door knob of the driver's seat door is operated, the driver enters the driver's seat and the ignition key is inserted.
Then, a command is sent to the ion generator 8 to further start ion emission from the ionization needle set 8c of the ignition unit 18. Here, the timer T0 of the timer 6 is reset.

In the next step 105, it is checked whether or not an engine (not shown) has been started based on a signal from the ignition sensor 4. If the engine has been started, the process proceeds to step 106;
Go to 0. In step 106, the vehicle speed is checked based on the signal from the vehicle speed sensor 5. If the engine is started and the vehicle is running, there is no possibility that a new occupant will get on the vehicle. Therefore, the process proceeds to step 113, in which all ion emission is stopped, and the flow ends. On the other hand, if the vehicle is still stopped, it is determined that there is a possibility that a new occupant will get on the vehicle, and step 106 is repeated until the traveling of the vehicle is detected.

If none of the external door knobs has been operated in the check in step 103, step 10
In step 8, a comparison is made between the time T0 of the timer 6 and a predetermined time T1 set in advance. The predetermined time T1 is set, for example, to 10 minutes as a time from when the door lock is opened until when the occupant gets on the vehicle. While T0 <T1, the process returns to step 103 to repeatedly check the operation of the external door knob of each door. Then, when T0 = T1, it is determined that there is no possibility of the occupant getting on the vehicle, and in step 109, ion emission from the external door knob unit 11 and the window frame unit 15 is stopped, and the flow ends.

If the engine has not been started in the check in the previous step 105, in step 110,
The time T0 of the timer 6 and a predetermined time T2 set in advance
Compare with. The predetermined time T2 is set, for example, to 5 minutes as a time from the first operation of the external door knob to the start of the engine. Step 105 during T0 <T2
Return to and repeat the engine start check. And
When T0 = T2 is reached without being started, it is determined that there is no ride thereafter, and all the ion emission is stopped in step 111, and the flow is terminated.

As described above, when the operation control unit 7 detects that the door lock has been unlocked, the external door knob unit 11 and the window frame to which the occupant may first come in contact are set. Ion emission from the ion generator 8 is started in the unit 15, and the static electricity charged on the vehicle body or the occupant is neutralized. For example, a positive charge charged to the occupant neutralizes negative ions from the ionization needle, and static electricity is removed. Note that the polarity of electrification differs depending on the occupant's clothes and the like, and thus the polarity of ions required for neutralization is also different. However, since the ion generator 8 generates ions of both polarities, the polarity of the polarity required for neutralization is generated. The ions are automatically attracted, and the static electricity charged to the occupants and the vehicle is eliminated.

Subsequently, when the external door knob of the driver's seat door is operated, the ignition unit 1 comes into contact with the driver.
8 also emits ions. As a result, ions are supplied to a portion where the occupant may come into contact with the vehicle from the outside of the vehicle until the door is opened and the user enters the vehicle to start the engine and start traveling.

FIG. 4 is a flowchart showing a control flow when the occupant gets off the vehicle after the vehicle has finished traveling. This control is started by operating an internal door knob of any door. First, when it is detected in step 201 that the internal doorknob has been operated based on a signal from the internal doorknob sensor 3, in step 202, the vehicle speed is checked based on a signal from the vehicle speed sensor 5.

If the vehicle is running, it is impossible to get off the vehicle.
The control ends. If the vehicle is stopped, it is determined that the occupant intends to get off, and in step 203,
A command is sent to the ion generator 8 and the ignition unit 1
8, and ion emission is started from the ionization needle sets 8a, 8b, 8c of the external door knob 11 and the window frame 15 of each door.

In the next step 204, the operation state of the engine is checked based on the signal from the ignition sensor 4, and after the engine is stopped, the routine proceeds to step 205.
In step 205, it is checked whether or not the door lock has been closed by a signal from the door lock sensor 1. This check is repeated while the door lock is open, and when the door lock is closed, the process proceeds to step 206. If the door lock is closed following an engine stop,
Since all the passengers get off the vehicle and are locked to leave the vehicle, in step 206, all the ion emission is stopped, and the flow ends.

As described above, at the time of dismounting, when the operation control unit 7 detects that the internal door knob has been operated,
Ion emission is started from the ion generator 8 in the ignition part 18, the external door knob part 11, and the window frame part 15, and static electricity charged to the vehicle body or the occupant is eliminated. Then, after the engine is stopped and the door lock is locked, the ion emission is stopped, so that the ion supply is continued to the portion where the occupant may come into contact until all the members get off.

In this embodiment, the above-mentioned step 10
1, 103, 105, 106, 108, 110, 20
1, 202, 204, and 205 constitute the detection means at the time of getting on and off the vehicle, and particularly, steps 101, 103, 105,
106, 108, and 110 constitute the on-board detection means, and steps 201, 202, 204, and 205 constitute the on-board detection means. Steps 102, 104,
107, 109, 111, 203 and 206 constitute operation control means.

The present embodiment is constructed as described above, and discharges ions to the external door knob 11, window frame 15, and ignition 18 to which the occupant may come in contact when getting on and off by the ion generator 8 provided in the vehicle. Therefore, even when a plurality of occupants get on and off the vehicle, static electricity charged to the occupant or the vehicle is neutralized with ions even if each occupant does not have a special device. Therefore, the ion generator 8
By appropriately setting the amount of ions released by the device, the static electricity is reduced to 3 kV, which is the generation limit of the electrostatic shock, and the effect of completely preventing the user from being exposed to the electrostatic shock by touching the external door knob or the like at the time of getting on and off can be obtained.

In addition, particularly when riding, when the door lock is unlocked, ions are first emitted toward the external door knob 11 and the window frame 15, and then the ignition is performed after the external door knob is operated. The ion is also emitted to the part 18, and after that, the running is started or the ion emission is stopped after a lapse of a predetermined time, so that the occupant does not need any special operation, and the parts corresponding to the transition of the ride are automatically and precisely timed. Ions are supplied. Also, at the time of getting off, ion emission starts when the internal door knob is operated to get off, and ion emission stops when the occupant gets off and the door lock is locked. Without special operations, the ions are automatically supplied and discharged only as long as necessary.

FIG. 5 is a block diagram showing a second embodiment. In this embodiment, a seating pressure sensor is added to the previous embodiment, and ions are also emitted to the seat portion. That is, each seat in the passenger compartment is provided with a seating pressure sensor 9 for detecting the seat pressure due to the seating of the occupant, and is connected to the operation control unit 7 'together with the sensors 1 to 5 and the timer 6 in the previous embodiment. Have been.

The ion generator 8 'controlled by the operation control unit 7' includes an external door knob unit, a window frame unit, and an ignition unit (see the external door knob unit 11, the window frame unit 15, and the ignition unit 18 in FIG. 2) of each door. ) And ionization needle sets 8a, 8b, 8 installed on each sheet part, respectively.
c and 8d to generate negative ions and positive ions. As shown in FIG. 6, the ionization needle set 8 d in the seat portion 20 is installed so as to emit ions mainly along the seat back 21, and an occupant is charged with static electricity by friction caused by rubbing the back of the seat back 21. To supply the ions to neutralize them.
Other configurations are the same as those of the first embodiment.

The control at the time of boarding in the operation control section 7 'is the same as in the first embodiment, and the description is omitted. FIG. 7 is a flowchart showing a flow of control performed by the operation control unit 7 'when the occupant gets off the vehicle. Steps 301 and 302
Are steps 201 and 2 in the flowchart of FIG.
Same as 02, steps 307 to 309 are 204 to 206
Is the same as If it is determined in step 302 that the vehicle is running, it is impossible to get off the vehicle, so that the operation of the internal door knob is erroneously performed, and the control ends. If the vehicle is stopped, it is determined that the occupant intends to get off, and the process proceeds to step 303.

In step 303, a command is first sent to the ion generator 8 'to start ion emission in the ignition section. Thus, even if the driver touches the ignition key to stop the engine, the driver is not shocked by static electricity. Then, in the next step 304,
A seating state of the occupant in each seat is detected based on a signal from the seating pressure sensor 9. If there is a change in which the pressure decreases by the predetermined value P0 or more in any of the seats, it is determined that the occupant seated on the seat has raised his waist to get off, and the process proceeds to step 305 to the ion generator 8 ′. A command is sent to start ion emission from the sheet unit 20.

Subsequently, in step 306, ion emission to the external door knob and window frame is started. This step 306 is executed when the predetermined pressure change has occurred in any of the sheets in the check in step 304. Thereafter, in step 307, the operation state of the engine is checked, and in step 308, it is checked whether the door lock is closed. When the door lock is closed, all the passengers get off the vehicle and are locked to leave the vehicle. The steps after step 307 are the same as in the previous embodiment.

Here, for the sheet whose pressure change is smaller than the predetermined value P0 in the check in the previous step 304, this step 304 is repeated until the closed state of the door lock is detected in step 308, though not particularly shown. When there is a pressure change equal to or more than the predetermined value P0, the ion emission in the sheet portion 20 is started. As a result, even if the occupants who have boarded are displaced from each other at different times, ions are supplied to their seat portions 20 in a timely manner, and the static electricity charged during riding is neutralized.

In this embodiment, steps 301 and 3
02, 304, 307 and 308 constitute the detection means at the time of getting off according to the present invention, and steps 303, 305, 306 and 309 correspond to steps 102, 10 and 10 in the flow of FIG.

The present embodiment is constructed as described above. At the time of getting off the vehicle, when the internal doorknob is operated, first, ion emission is started to the ignition portion, and further, the seating pressure sensor 9 provided on each seat is used to sense the occupant's feeling. When the getting-off operation is detected, ions are also emitted to the external door knob portion and the window frame portion. Therefore, in addition to the effect of the first embodiment, the ion is automatically automatically transmitted to portions corresponding to the transition of getting off with good timing. Is supplied. In particular, even when the timing of the getting-off operation of each occupant is deviated, the ions are released to the seat portion 20 in accordance with the time when the occupant raises his / her waist and descends, so that it is highly accurate and efficient. An ion supply is performed.

In each embodiment, the external door knob sensor 2 and the internal door knob sensor 3 are provided for each of a plurality of doors, and the timing of getting on and off is detected based on the operation of the external door knob sensor or the internal door knob sensor of one of the doors. However, in general, the driver's getting on and off operation often precedes the other passenger's getting on and off operation. By discharging ions to the door knob portion, the window frame portion, and the like, the electrostatic shock is effectively prevented in most cases.
