Abstract

PURPOSE:To make it easy to find a hiding burgler or the like by lighting a room lamp in a passenger compartment by receiving a signal transmitted wirelessly from a portable transmitting means on a vehicle body side when the transmitting means approaches a certain distance from the vehicle. CONSTITUTION:When a passenger carrying a transmitting means 9 intends to ride a vehicle and approaches the vehicle at night within a certain distance from the vehicle body 1, the fact is detected by the reception of a wireless signal transmitted from the transmitting means 9 by means of a transmitting means detection means 22. And a room lamp 3 is lit by means of a control means 23 receiving an output signal from the detection means 22 to illuminate the inside of a passenger compartment 2. Thus, since the room lamp 3 is lit without opening a door but by only approaching the vehicle body 1 within a certain distance from the vehicle body 1, if a burgler or the like is hiding in the passenger compartment 2, it is easily detected by the illumination of the room lamp 3. As a result, safety at the time of riding a vehicle can be enhanced.

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an electrical component control device that controls the operation of electrical components installed in a vehicle, and in particular, an electrical component control device that controls the lighting of interior lights as an electrical component. It is related to.

(Prior Art) Generally, an interior light for illuminating the interior of the vehicle at night is attached to, for example, the ceiling of the interior of a vehicle. When controlling the lighting of this interior light, it is usually turned on by manual operation by a passenger inside the vehicle, and also when the door is opened to assist the passenger in getting in and out of the vehicle. As an example, for example, Japanese Utility Model Application Publication No. 59-102543 discloses a control device which detects a door opening operation using a door switch and turns on an interior light.

(Problems to be Solved by the Invention) By the way, there is a theft called a stealth robbery in which a vehicle sneaks into a vehicle at night when no occupants are present, hides there, attacks the occupants as they enter the vehicle to drive, and steals money and goods. . However, when the interior light is turned on in response to the door opening operation as in the conventional example above, a person hiding inside the vehicle can only be detected at the same time as the door opening operation, making it difficult to deal with hidden robbers, etc. It was something that could not be done.

The present invention has been made in view of the above, and its purpose is to provide a control system that can automatically turn on the interior lights under predetermined conditions even if the occupant is a certain distance from the vehicle body. To make it possible to illuminate the interior of a vehicle without having to open the door, thereby easily detecting a hidden burglar or the like and allowing safe riding at night.

The C card 9 is a portable IC card having a built-in device (not shown); ) and a predetermined signal to the antenna 10.
It has a transmitter 11 that transmits data wirelessly. Therefore, this IC card 9 constitutes a portable transmitting means for transmitting a predetermined signal.

Further, reference numeral 12 indicates a vehicle body 1 for controlling the operation of the interior light 3, the electric seat 5, the electric mirror 6, and the electric tilt device 7.
This controller 12 is a controller provided on the side, and this controller 12 includes a CPU 13 having an arithmetic processing function, a ROM 14 and a RAM 15 as data storage means, and a timer 16 for measuring time. And the above CPU1
3 is an inverting circuit 17 and a transistor T for the interior light 3.
When a lighting command signal is output from the CPU 13, the transistor Tr is turned on and the interior light 3 is turned on.

The controller 12 also includes a receiving section 18 that receives a signal transmitted from the transmitting section 11 of the IC card 9 through an antenna 18a, and an electric field strength that detects the electric field strength of the wireless signal received by the receiving section 18. A detection unit 19 is provided.

Furthermore, the CPt, 113 has an ignition key switch 2 for operating the vehicle engine (not shown).

After that, in step S5, it is determined that the ignition key switch 20 is in the ON state, and when this determination is No, indicating that the ignition key switch 20 is in the OFF state, the process advances to step S6, and the timer 16 clocks the interior light. It is determined whether a certain period of time has elapsed since the start of the lighting in step 3, and if it is determined that the certain period of time has not yet elapsed, then
Return to step S4 above. Then, when the ignition key switch 20 is turned on and the determination at step S5 becomes YES, or when the determination at step S6 becomes YES after a certain period of time has elapsed, step S
After proceeding to step 7 and turning off the interior light 3, the process ends.

Therefore, in this embodiment, in steps 81 to S3 in the above control procedure, it is determined that the electric field intensity due to the I-line signal transmitted from the IC card 9 as the transmitting means has increased above a certain value. The IC card 9
A transmitting means detecting means 22 is configured to detect when the transmitting means approaches within a predetermined distance range.

Further, in steps 84 to S7, upon receiving the output of the transmitting means detecting means 22, the indoor light 3 is turned on when the IC card 9 approaches within a predetermined distance range, and after that, when a certain period of time has elapsed, or A control means 23 is configured to turn off the interior light 3 when the ignition key switch 20 is turned on.

Next, the operation of the above embodiment will be explained.

When entering cabin 2 to drive a car at night,
A radio wave with a predetermined signal is transmitted from the transmitting section 11 of the IC card 9 in advance, and the passenger holding the IC card 9 approaches the vehicle body 1.
When the passenger approaches the IC card 9, a wireless signal from the IC card 9 is received by the receiver 18 of the controller 12, and when the passenger, that is, the IC card 9, reaches within a predetermined distance range, the electric field strength increases beyond a certain value, and a wireless signal from the controller 12 is received. A lighting command signal is output and the interior light 3 is turned on. Therefore, the interior light 3 is automatically turned on when the occupant approaches the vehicle body 1 within a predetermined distance without opening the door 4, so even if there is a robber etc. hiding inside the vehicle interior 2, The driver can easily see the person from outside the vehicle, avoid any harm, and can therefore ride safely.

Also, after this, the occupant who has opened the door 4 and entered the passenger compartment 2 turns the ignition key switch 20 to O to start the engine.
Even if the user performs the N operation or does not enter the vehicle interior 2, the interior light 3 that has been lit is automatically turned off when a certain period of time has elapsed from the time when the interior light 3 started lighting. Therefore, there is no need for the occupant to take the trouble and care to turn off the interior light 3.

Incidentally, when the passenger entering the vehicle compartment 2 inserts the IC card 9 into the reader/writer, the IC card 9 and the controller 1
2 are directly electrically connected, and due to this connection, the CPU 14 of the controller 12 and the CPU of the IC card 9 exchange signals, and the control data stored in the storage section of the IC card 9 is transferred to the RAM 15 of the controller 12. Based on the read control data, the electric seat 5, electric mirror 6, and electric tilt device 7
are operated and controlled via a drive unit, and the positions of the electric seat 5 and electric mirrors 6, as well as the tilt position of the steering wheel 8, are adjusted to optimal positions for the occupant.

When getting off the vehicle, the IC card 9 and the controller 12 are electrically connected, signals are exchanged between them, and the signals are detected by the position detection section of the controller 12, in the same way as the adjustment after getting on the vehicle. Data regarding the positions of the electric seat 5, electric mirror 6, etc., are written and stored in the storage section of the IC card 9.

In the above embodiment, the IC card 9 having the transmitting section 11 is shown as a portable transmitting means for wirelessly transmitting a signal, but the present invention is not limited to this, and for example, a general small radio device may be used. .
