DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a vehicle which switches the vehicle to a running state by using an electric means instead of a mechanical key.

[0002]

2. Description of the Related Art As means for switching an automobile to a state in which it can run, it is common to provide an ignition switch operated by a mechanical key. However, such means using a mechanical key include: There is a situation in which the security against unauthorized operation of the ignition switch (that is, theft of a car) is relatively low.

Therefore, conventionally, an IC card card key storing a vehicle ID registered in advance for each vehicle is prepared, and the card key is inserted into a slot provided on the automobile side. The vehicle ID is read from the card key, and when the read vehicle ID matches the vehicle ID registered in advance in the vehicle, the operation of the ignition switch is validated.

[0004]

In the above configuration, the determination as to whether or not to activate the operation of the ignition switch is made by relying only on the card key. It is hard to say that it has been fully realized, and there is room for improvement in this respect.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle control device having an effect of greatly improving security against vehicle theft.

[0006]

According to the present invention, in order to achieve the above object, a predetermined vehicle ID is stored and a unique ID is stored.
A portable card holder capable of mounting a card-shaped record carrier on which a D code is recorded, and a card holder provided on the card holder side;
Registration means for registering the ID code recorded on the record carrier as a personal ID in advance; transmission means provided for transmitting the vehicle ID to the card holder side; and detachable attachment of the card holder to the vehicle side And a slot provided on the vehicle side so as to correspond to the slot, and a state in which a transmission signal from the transmitting means can be received in a state where the card holder is inserted in the slot. And a transmitting device, wherein the transmitting means has an ID code corresponding to a personal ID registered in the registering means for the card holder when the card holder is inserted into the slot. The transmission of the vehicle ID is performed on condition that the record carrier is mounted, and the control device is included in the card holder. When receiving the vehicle ID from the signal means, the vehicle ID to which the vehicle ID is previously stored in the vehicle
Only when the vehicle speed is equal to the vehicle operating mode, the operation mode is switched to the operation mode in which the turning-on of the vehicle electric system is permitted (claim 1).

[0007] According to this configuration, when the electric system for the vehicle is turned on by using the card holder, the data is recorded on the record carrier owned by itself by the registration means provided on the card holder side. The registered ID code is registered in advance as a personal ID, and in a state where such a registered record carrier is mounted on the card holder, the same vehicle ID as the vehicle ID stored in the card holder is stored in the card holder. Into the slot provided on the vehicle side.

[0008] In this case, since the recording medium having the ID code matching the personal ID registered in the registration means is mounted on the card holder, the transmission means provided on the card holder side is provided. Then, the transmission operation of the vehicle ID stored in the card holder is performed. Also, the control device on the vehicle side is in a state where it can receive the transmission signal from the transmission means at the time when the card holder is inserted into the slot, and the vehicle I transmitted as described above is transmitted.
When the vehicle ID is received, the vehicle ID coincides with the vehicle ID stored in advance on the vehicle side, so that the operation mode is switched to an operation mode in which the input of the vehicle electric system is permitted, and thus the vehicle electric system is switched. The system can be turned on.

In short, in order to switch the control device to the above-described operation mode, that is, a state in which the vehicle can travel, an ID matching the personal ID registered in advance in the registration means is required.
It is premised that a card holder having a record carrier on which a code is recorded is inserted into a slot. In other words,
In order to run the vehicle, both the record carrier and the card holder are required, so that the security against theft of the vehicle is greatly improved.

[0010] Further, the registration means may include a plurality of types of personal I
D can be registered (claim 2). According to such a configuration, a plurality of persons, such as a family of a vehicle owner, can use the function of turning on the vehicle electrical system by the card holder. become able to.

Further, in the state where the control device is once switched to the operation mode, the control device maintains the operation mode even after the record carrier is removed from the card holder attached to the slot. It is desirable (claim 3).

According to this configuration, the record carrier is also used as a carrier having other functions such as a credit card and a driver's license, so that the added value thereof and the convenience of the user can be improved. This is useful when a configuration is adopted. In other words, for example, when the record carrier is constituted by a credit card, when the credit card is used for settlement of a toll on an expressway, the credit card must be removed from the card holder. However, even in such a case, the operating state of the vehicle electrical system is maintained as it is, so that there is no danger of inconvenience in practical use.

After the card holder is provided with a mode changeover switch, the transmitting means is operated in a state where a record carrier having an ID code matching the personal ID registered in the registering means is mounted on the card holder. When the mode changeover switch is operated, the vehicle ID may be transmitted when the card holder is inserted into the slot, irrespective of the mounting state of the record carrier in the card holder. ).

According to this configuration, the control device can be switched to the operation mode in which the connection of the vehicle electric system is permitted, using only the card holder. Therefore, for example, when a vehicle is used by a third party, it is only necessary to hand over the card holder and there is no need to hand over the record carrier, so that the security of the record carrier is not likely to be hindered.

The card holder has a function of transmitting an aerial propagation signal for a keyless entry system for a vehicle, and the transmission function is changed to an ID matching the personal ID registered in the registration means. The configuration may be such that the card holder is enabled only when the record carrier having the code is mounted (claim 5). According to this configuration, the card holder can be made multifunctional and the added value thereof can be improved. You will be able to plan.

An internal IC chip (not shown) stores card data including a personal ID code unique to the owner. The master ID card 7 is attached to the card holder 4 one by one, and an internal IC chip (not shown) includes a card data including a master ID code unique to the corresponding card holder 4. Is stored.

In this case, although not specifically shown, the above I
The D card 6 and the master ID card 7 are provided with signal transmission / reception means for transmitting / receiving signals to / from external devices and supplying power, and each signal transmission / reception means is provided with an ID interrogation signal as described later. Is received, the personal ID code or the master ID code is read out and answerback is performed.

The card holder 4 has a slit 4a for inserting an ID card 6 or a master ID card 7 at an end face.
It is formed in a flat rectangular container shape provided with On the upper surface of the card holder 4, a lock switch 8a and an unlock switch 8b for a keyless entry system for an automobile door lock mechanism are provided, and a mode changeover switch 9 having a function described later is provided. ing. The lock switch 8a and the unlock switch 8b are constituted by momentary switches.
The mode changeover switch 9 is constituted by an alternate type switch.

In the card holder 4, in addition to a battery for power supply (not shown), a control unit (shown by reference numeral 10 in FIG. 4) for making the card holder 4 function as an engine key for an automobile. Is provided.

The control unit 10 can be mainly composed of, for example, a one-chip CPU. FIG. 4 shows a part of the configuration of the control unit 10 in which parts related to the keyless entry system are omitted. , An example represented by a block diagram is shown. Therefore, in the following, the control unit 1 shown in FIG.
0 will be described.

That is, in FIG.
1 is configured to turn on when a card is inserted through the slit 4a. When the card is turned on, the power of the communication device 12 is turned on through a power supply terminal + VDD connected to the power supply battery (not shown). It has become so.

When the inserted card is the ID card 6 or the master ID card 7, the communication device 12 transmits and receives signals to and from the ID card 6 or the master ID card 7. is there. In particular,
When the communication device 12 is activated in response to power-on,
An ID inquiry signal is transmitted to the ID card 6 or the master ID card 7 in the inserted state, and the personal ID code or the master ID which is answered back as a serial signal from the ID card 6 or the master ID card 7 in response thereto. It is configured to receive a code.

The master ID collating device 13 is a communication device 12
Stores the master ID code received by the master ID storage device 1
4 is compared with the master ID code stored in No. 4, and if the comparison result matches, the OK signal (high level signal)
And outputs an NG signal (high-level signal) when they do not match.

In this case, the same master ID code as that of the master ID card 7 attached to the card holder 4 is stored in the master ID storage device 14 in advance. Therefore, in the master ID collation device 13, the slit 4a
When the master ID card 7 attached to the card holder 4 is inserted, an OK signal is output, but when another card (including the ID card 6) is inserted, an NG signal is output. .

The personal ID collating device 15 stores the personal ID code received by the communication device 12 in the personal ID storage device 16 (corresponding to the registration means in the present invention).
, And outputs an OK signal (high-level signal) when the results match, and outputs an NG signal (high-level signal) when the results do not match.

In this case, for example, three types of personal IDs corresponding to three different ID cards 6 can be registered (stored) in the personal ID storage device 16 as described later. Therefore, in the personal ID verification device 15, when the ID card 6 registered in advance is inserted into the slit 4a, an OK signal is output, but other cards (including the master ID card 7) are inserted. When this is done, an NG signal is output.

The master ID collating device 13 and the personal ID
The NG signal from the matching device 15 is provided to a pair of input terminals of the AND circuit 17. The output terminal of the AND circuit 17 is connected to a buzzer 18 via an amplifier (not shown). As a result, when a card other than the master ID card 7 attached to the card holder 4 or the ID card 6 registered in the personal ID storage device 16 is inserted into the slit 4a,
The buzzer 18 is driven to output an alarm sound.

The RS flip-flop 19 is connected to the master I
It is set by an OK signal from the D collation device 13 and reset by an OK signal from the personal ID collation device 15. The AND circuit 20 is configured to receive a signal from the output terminal Q of the RS flip-flop 19 at one input terminal and a personal ID code received by the communication device 12 at the other input terminal. The output is provided to the personal ID storage device 16.

Therefore, when the master ID card 7 attached to the card holder 4 is inserted into the slit 4a, the R-signal is received by the OK signal from the master ID collating device 13.
Since the S flip-flop 19 is set, the AND circuit 20 is in a state where the personal ID code received by the communication device 12 can be given to the personal ID storage device 16. For this reason,
Thereafter, when the ID card 6 is inserted into the slit 4a instead of the master ID card 7, the personal ID code stored in the ID card 6 is given to the personal ID storage device 16, and The personal ID storage device 16 uses the personal ID code thus input as a personal ID in three types (in FIG. 4, three types of personal ID (A),
(Represented by (B) and (C)).

After the personal ID code is updated and registered as described above, an OK signal is output from the personal ID collating device 15 and the RS flip-flop 19 is reset. Therefore, when registering a personal ID code,
Each time, it is necessary to perform the operation of inserting the master ID card 7.

The master ID collating device 13 and the personal ID
Each OK signal from the matching device 15 is supplied to input terminals of AND circuits 22, 23, and 24 through an OR circuit 21 (the AND circuit 24 is a three-input type). The above AND
The other input terminal of the circuit 22 is configured to receive a high-level signal when the mode changeover switch 9 connected to the power supply terminal + VDD is turned on. The output of the AND circuit 22 is provided to the set input terminal S of the RS flip-flop 25.

Therefore, the master ID card 7 attached to the card holder 4 or the personal ID
When the mode switch 9 is turned on with any of the registered ID cards 6 inserted in the storage device 16, the RS flip-flop 25 is switched to the set state.

A high-level signal is applied to the other input terminal of the AND circuit 23 through the inverter circuit 26 with the mode changeover switch 9 turned off. The output of the AND circuit 23 is RS
The reset input terminal R of the flip-flop 25 is provided.

Accordingly, the master ID card 7 attached to the card holder 4 or the personal ID
When the mode switch 9 is turned off with any of the registered ID cards 6 inserted in the storage device 16, the RS flip-flop 25 is switched to the reset state.

A signal from a reset output terminal Q ^* of the RS flip-flop 25 and an output signal from the vehicle ID storage device 27 are provided to other input terminals of the three-input type AND circuit 25. Has become. The output signal from the vehicle ID storage device 27 is output to the AND circuit 2
8, and a signal from a set output terminal Q of the RS flip-flop 25 is supplied to the other input terminal of the AND circuit 28.

Therefore, the output signal from the vehicle ID storage device 27 is an OK signal from either the master ID verification device 13 or the individual ID verification device 15 when the RS flip-flop 25 is reset. When the RS flip-flop 25 is set, the signal passes through the AND circuit 28 irrespective of the OK signal.

Here, the vehicle ID storage device 27 stores the same vehicle ID as the unique vehicle ID stored in the corresponding automobile, and is switched to the active state by the vehicle ID receiving device 29. , Stored vehicle ID
Is output as a serial signal. still,
The vehicle ID receiving device 29 is provided so as to be able to receive a vehicle ID interrogation signal output from the automobile as described later, and switches the vehicle ID storage device 27 to an active state in the receiving state.

Output signals from the AND circuits 24 and 28 are supplied to a vehicle ID transmitting device 31 (corresponding to transmitting means in the present invention) via an OR circuit 30. The vehicle ID transmission device 31 uses the vehicle ID stored in the vehicle ID storage device 27 as the AND circuits 24 and 2.
8 is started when the signal is given through any one of the above, and the vehicle ID signal is transmitted to the automobile.

In short, in the card holder 4, an appropriate master ID card 7 is inserted into the slit 4a.
After inserting (attached to the card holder 4),
By inserting the ID card 6 instead of the master ID card 7, the personal ID code of the ID card 6 can be stored (registered) in the personal ID storage device 16,
Up to three such ID cards 6 can be registered.

When the mode changeover switch 9 is turned off (the RS flip-flop 25 is reset), an OK signal is output from either the master ID matching device 13 or the personal ID matching device 15. In the case (appropriate master ID card 7 or registered I
Only when the D card 6 is inserted), the vehicle ID signal is transmitted from the vehicle ID transmitting device 31 in response to the vehicle ID inquiry signal from the automobile.

On the other hand, when the mode changeover switch 9 is turned on (when the RS flip-flop 25 is set), the vehicle ID interrogation signal from the automobile is received independently of the above-mentioned OK signal. The mode is switched to the lending mode in which the vehicle ID signal is transmitted in response. That is, in the ON state of the mode change switch 9, the mode is switched to the lending mode, and the transmission prohibition function of the vehicle ID signal using the master ID and the personal ID is invalidated.

FIG. 5 is a flowchart outlining the main control contents of the control unit 10 configured as described above. However, in FIG.
The “card registration permission” step (a) corresponds to control for setting the RS flip-flop 19. Thus R
When the -S flip-flop 19 is set, "YES" is determined in the step (b), and the step (c) is performed.
In, control for registering the personal ID code of the inserted ID card 6 in the personal ID storage device 15 is performed.

Step (d) performed with the mode changeover switch 9 turned on is the RS flip-flop 2.
Setting to 5 corresponds to control for switching to the lending mode in which the transmission prohibition function by the master ID and the personal ID is invalidated. In step (e) of determining whether or not the ID is invalid, control is performed to determine “YES” while the RS flip-flop 25 is set.

Although not shown in FIG. 5, the above R-
The resetting of the S flip-flop 25 (cancellation of the lending mode) is performed, for example, when an appropriate master ID card 7 or a registered ID card 6 is inserted into the slit 4a with the mode changeover switch 9 turned off (master I).
This is performed when an OK signal is output from one of the D collation device 13 and the personal ID collation device 15).

Although not specifically shown, the control unit 10 included in the card holder 4 transmits an airborne signal for a keyless entry system for a door lock mechanism of an automobile to a lock switch 8a and an unlock switch. The ID card 6 having an ID code matching the personal ID registered in the personal ID storage device 16 is attached to the slit 4a. It is activated only when the card is inserted or when the master ID card 7 attached to the card holder 4 is attached.

On the other hand, FIG. 1 shows a portion related to the gist of the present invention in the electrical configuration provided on the automobile side, which will be described below. In FIG. 1, a control device 32 provided so as to correspond to the slot 3

Specifically, the communication device 37 transmits a vehicle ID interrogation signal to the card holder 4 in the inserted state when the communication device 37 is activated in response to power-on, and responds to the answer from the card holder 4 side. The vehicle ID signal to be backed is received.

The ID collating device 38 collates the vehicle ID signal received by the communication device 37 with the vehicle ID stored in the ID storage device 39 in advance, and when the collation results match, an OK signal (high level). Signal), and outputs an NG signal (high-level signal) if they do not match.

In this case, the same vehicle ID as that stored in the vehicle ID storage device 27 (see FIG. 4) of the card holder 4 is stored in the ID storage device 39 in advance. Therefore, in the ID collation device 38, the slot 3
In response to this, a proper card holder 4 (in which the vehicle ID is the same as the vehicle ID stored in the ID storage device 39) and the proper master ID card 7 or the registered Card holder 4 with completed ID card 6 mounted, or vehicle ID
When the card holder 4) is inserted while the card holder 4) is still in the state of being switched to the lending mode, the OK signal is output. Otherwise, the NG signal is output.

According to the configuration of the present embodiment, the following effects can be obtained. In order to switch the control device 32 provided on the vehicle side to an operation mode in which the rotation operation of the ignition switch 5 is permitted, that is, to a state in which the vehicle can travel, the card holder 4 which functions as a so-called electronic key is inserted into a slot. In this case, it is assumed that the card holder 4 in which the ID card 6 registered in advance is attached to the personal ID storage device 16 in the card holder 4 is used. Become. In other words, since the ID card 6 and the card holder 4 are both required to run the automobile, the security against theft of the automobile is greatly improved.

In this embodiment, the master IC card 7 attached to the card holder 4 can be used to switch the control device 32 to the operation mode. Since is not always carried, it does not hinder the improvement of security.

Further, for the personal ID storage device 16,
Since up to three different ID cards 6 can be registered, the electronic key function by the card holder 4 can be used by a plurality of persons such as a family of a car owner, and the convenience is improved.

Further, in the state where the control device 32 is once switched to the operation mode, even after the ID card 6 is removed from the card holder 4 mounted in the slot 3,
Since the operation mode is maintained, the ID card 6 is also used as a credit card as in the present embodiment to improve the added value and the convenience of the user. It is useful when

That is, when the ID card 6 is composed of a credit card and the ID card 6 is used for settlement of a toll on an expressway, etc.
Although it is necessary to remove the card 6 from the card holder 4, even in such a case, the operation mode is maintained as it is, so that there is no danger of practical inconvenience. It should be noted that a configuration in which the ID card 6 is also used as a driver's license or the like is possible, and a similar effect can be obtained with such a configuration.

In addition, according to this embodiment, on the card holder 4 side, an appropriate master I
When the mode changeover switch 9 is turned on with either the D card 7 or the registered ID card 6 inserted, the card holder 4 in which the ID card 6 or the master ID card 7 is not mounted is inserted into the slot. 3, the control device 32 can be switched to the operation mode as described above. Therefore, for example, when a car is used by a third party at the time of car washing at a gas station or the like, only the card holder 4 needs to be handed over and the ID card 6 does not need to be handed over. Is not likely to be hindered.

Since the card holder 4 is provided with a function of transmitting an airborne signal for a keyless entry system for an automobile, the card holder 4 can be made multifunctional and further added value. Can be improved.

The present invention is not limited to the above-described embodiment, but can be expanded or modified as described below. The present invention can be applied to electric vehicles and the like. Although the example in which the ID card is constituted by an IC card has been described, the ID card may be constituted by a magnetic card. Although the rotary type ignition switch 5 is provided, the ignition switch may be configured by combining push button switches.
