FIG. 1 is a block diagram showing the overall configuration of the vehicle-side device according to the embodiment. The first transmitting antenna 10 is built in a door outer handle (a door opening handle on the outside of the door) provided outside the door of the driver's seat (D seat), for example. The first transmitting antenna 10 transmits radio waves having relatively high directivity, for example, 2.45.
An ID request signal is transmitted to the outside of the vehicle by a radio wave of GHz. The first transmitting unit 12 performs a process for transmitting the ID request signal from the first transmitting antenna 10. The second transmitting antenna 14 is provided near the instrument panel inside the vehicle, and transmits an ID request signal toward the inside of the vehicle by, for example, a radio wave of 2.45 GHz. The second transmission unit 16 performs a process for transmitting the ID request signal from the second transmission antenna 14. Note that the first transmission unit 12 and the second transmission unit 1
6 can be shared by one circuit. Also,
Separate transmission antennas are installed on the passenger side and the driver side,
Control such as only unlocking the corresponding door in response to the response to each ID request signal is also possible.

The receiving antenna 18 is provided in the vehicle interior,
Receives a signal transmitted from the portable device. The signal from the portable device is, for example, a 300 MHz signal, and is a response including an ID to the ID request signal. The receiving unit 20 processes a signal received by the receiving antenna 18.

The first transmitter 12, the second transmitter 16 and the receiver 20 are connected to an ECU 22. This ECU2
2 is a first transmitting unit 12, a second transmitting unit 16, and a receiving unit 20
And various other processes are performed.

An input unit 24 is connected to the ECU 22. The input unit 24 is operated to input various signals. The input unit 24 is, for example, a button switch.

A courtesy switch 26 is connected to the ECU 22. This courtesy switch 26
This switch is turned on and off by opening and closing the door. In this case, it indicates opening and closing of the D seat door. The ECU 22 can recognize the opening and closing of the D seat door by turning on and off the courtesy switch 26.

A memory 28 is connected to the ECU 22. The memory 28 stores data on the ID of the portable device. Therefore, the ECU 22
ID stored in the memory 28 (storage ID)
And the ID (reception I) received from the portable device.
ID matching is performed by comparing D). The memory 28 is preferably a non-volatile memory.
EPROM is used. With an EEPROM, the contents of the memory 28 can be rewritten when necessary.
It is also preferable that the ID for unlocking the door and the ID for unlocking the immobilizer and the steering lock are separately stored in the memory 28.

A door lock 30, an immobilizer 32, and a steering lock 34 are also connected to the ECU 22. The door lock 30 controls locking and unlocking of the door, and drives and locks the locking mechanism by driving a motor or the like to lock and unlock the door. It is preferable that lock / unlock of all seat doors and individual doors can be controlled in addition to lock / unlock of only the D seat door. The door lock 30 is controlled according to a response of the portable device to an ID request from the first transmitting antenna 10.

The immobilizer 32 controls permission / non-permission of starting the engine. If it is confirmed that a legitimate portable device is possessed by exchanging the ID with the portable device, the engine is permitted to start. Steering lock 3
Reference numeral 4 denotes a steering lock, which is released when a valid portable device is recognized, similarly to the immobilizer 32. The immobilizer 32 and the steering lock 34 are controlled according to a response of the portable device to an ID request from the second transmitting antenna 14.

[Structure of Portable Device] FIG. 2 shows the structure of the portable device. The receiving antenna 40 is a first antenna of the vehicle-side device.
And a 2.45 GHz radio wave (ID request signal) transmitted from the second transmitting antennas 10 and 14. The receiving unit 42 is connected to the receiving antenna 40 and performs a receiving process of a signal received by the receiving antenna 40. An ECU 44 is connected to the receiving unit 42.
Performs various processes including the signal supplied from. ECU44
Is connected to a memory 46, which stores data on ID. For example, two types of IDs for unlocking the door and unlocking the immobilizer and the steering lock are stored. The memory 46 is formed of, for example, a ROM.
It can also be made rewritable. EC
A transmission antenna 50 is connected to U44 via a transmission unit 48, and modulates a predetermined carrier with ID data and transmits the modulated data. The carrier frequency is, for example, 300 MHz
And received by the receiving antenna 18 of the vehicle-side device. Further, an operation unit 52 is connected to the ECU 44, and by operating the operation unit 52, an ID can be transmitted even when an ID request signal is not received. For example, similarly to a conventional keyless entry, a signal such as a door unlock can be transmitted, and a portable device signal, which will be described later, is transmitted in response to an operation of the operation unit 52.

"ID request and response" In such a system including the vehicle-side device and the portable device, when the door is locked with the engine turned off and the user leaves the vehicle, the vehicle-side device is An ID request signal is transmitted from the first transmitting antenna 10 at predetermined time intervals. For example,
As shown in FIG. 3, the ID request signal is repeatedly transmitted at 200 msec intervals.

Here, the ID request signal is coded as shown in FIG. That is, an ID request bit, which is a code signal of the ID request signal, is added to the ID request signal, and a response trigger request for maintaining the state of “1” is provided following the ID request bit. The ID request bit is composed of a plurality of bits, and the ID request signal can be identified by decoding the ID request bit. Each portable device is assigned an ID request bit for itself, decodes the ID request bit, recognizes the ID request bit addressed to itself, and returns a response only to the ID request signal addressed to itself.

The response trigger request is a signal indicating that a response from the portable device is being received. Therefore, if no response is received within a predetermined time,
Returned to "0". When a response is received, the state of “1” is maintained while ID comparison is being performed. In the figure,
The broken line shows an example in which the ID matching has failed, and the solid line shows an example in which the ID matching has succeeded. A predetermined start bit can be added before or after the ID request bit.

Here, in the illustrated example, the ID is used for simplification.
Although the request has 4 bits, it is preferable that the request has, for example, about 8 bits. This gives 2 ⁸ = 25
Six types of codes can be set. Further, the portable device stores data on the ID request bit addressed to itself in the memory 46.

FIG. 5 shows a timing chart when the portable device approaches and enters the reception range. First, when the portable device receives the ID request signal and recognizes that the ID request bit is addressed to itself, the ECU 4
4 reads out its own ID from the memory 46 and transmits this as a response from the transmitting antenna 50.

This response consists of a start bit and an ID bit as shown in FIG. The start bit is simply for notifying that the ID bit is transmitted, and the ID bit is the ID stored in the portable device.
Is data based on information about

The response from the portable device is received by the receiving antenna 18 of the vehicle-side device. In the example of FIG. 5, the portable device returns a response to the second ID request signal. As a result, the vehicle-side device continues to transmit the response trigger request.

Then, for the received ID, the ECU 2
2 matches the ID read from the memory 28. The response trigger request continues to be in the state of “1” while the matching of the response ID is being performed. Then, when the collation is successful (the IDs match), the response trigger is returned to “0” at that time. If the ID verification fails (the IDs do not match), the response trigger returns to “0” at that point. If the ID verification is successful (the IDs match), the ECU 22 controls the door lock 30 and releases the door lock 30.

[Registration Operation] The operation of registering a new portable device in the present embodiment in the vehicle-side device will be described with reference to FIG.

First, an input to enter the registration mode is made by operating the input section 24 of the vehicle-side device (S11), and the ECU enters the registration mode.
22 recognizes this, enters the registration mode, and returns a response with a buzzer or lighting of an appropriate display (S12). The operation for entering the registration mode may be any operation, but an operation that is not normally performed, such as simultaneously pressing a plurality of switches, is preferable.

Next, when entering the registration mode,
The transmission of the ID request signal is stopped (S13). This is because if an ID request signal is transmitted during the registration operation, the existing portable device or the like returns a response to the ID request signal, and the registration operation is not performed successfully. Note that the transmission stop of the ID request signal is automatically ended in response to the end or stop of the registration process.

The ID of the registered portable device that has already been registered is fetched (S14). The capture of the ID is performed by capturing a response signal including the ID transmitted in response to the manual push of the switch of the portable device.

That is, the vehicle-side device includes the receiving antenna 1
While waiting for the reception of the portable device signal in step 8, the operation of the registered portable device is waited. This is to confirm that the legitimate user has at least one correct portable device and is a legitimate user. When a portable device signal is acquired by operating a registered portable device, it is determined whether the IDs match (S15). If the determination is NO, the processing in the registration mode ends. Note that not only ID but also I
The D request bit (code) may also be transmitted from the portable device and confirmed.

If the determination in S15 is YES, a response indicating that registration standby for the new portable device has been completed is returned (S16). This response is made by, for example, a buzzer or a blinking of a predetermined display. Then, the vehicle-side device enters a state of waiting for a response. Therefore, the user operates the new portable device to transmit a portable device signal including an ID and an ID request bit (code) to be decoded. As a result, the vehicle-side device captures the ID and the ID request bit (code) to be decoded (S17). Then, an ID request bit previously allocated to the portable device is registered in the vehicle-side device.

Here, the portable device has an ID as shown in FIG.
A portable device signal including a request bit is transmitted in response to a manual operation. In this example, the portable device signal includes an 8-bit start bit, a 64-bit ID bit, and an 8-bit I bit.
The D request bit is followed by data such as parity. Then, by receiving the portable device signal, the vehicle-side device recognizes and registers the ID request bit in association with the ID bit. This registration is performed by storing in the memory 28.

Next, it is determined whether the format of the transmitted portable device signal is correct (S18). NO in this determination
If so, you cannot register for this mobile device,
The process ends. On the other hand, if the format is correct, I
It is determined whether the D request bit is different from that of the registered portable device (S19). And if the judgment is different,
The registration is OK and registered in the memory 28 (S20). If they match, the registration is not permitted and an error response is returned (S21).

As described above, according to the present embodiment, a portable device whose ID request bit matches a registered portable device is not registered. Therefore, it is possible to prevent a portable device having the same ID request bit from being registered for the same vehicle, and to avoid a collision of responses from the portable device. Further, the registration work only needs to press the button of the new portable device. Therefore, the registration operation can be performed without any problem even if the vehicle-side device does not have an input unit such as a numeric keypad.

In S20, if the registration is completed, the registered ID request bit is added to the I
It is also preferable to transmit the D request signal from the vehicle-side device and transmit the response to the portable device to check the registered contents. In this case, an ID request signal may be transmitted from the second transmitting antenna 14.

Further, in the above description of the operation, a single ID
Was registered, but I for door unlock
D and the ID for releasing the immobilizer are often different. In this case, the registration operation may be performed twice, or two IDs may be transmitted when a portable device signal is transmitted by pressing a button in the registration operation.

[Portable Device Signal] As described above, the portable device signal which is a response signal for registration must include an ID request bit. On the other hand, such information is not necessary for a response signal transmitted in response to an ID request signal in a normal state. Therefore, the ID request bit can be included only when a response signal (portable device signal) is transmitted by pressing the button of the portable device.

On the other hand, the ID request bit may always be included in the response signal. In this way, the portable device signal and the normal response signal become the same, and the processing in the portable device becomes easy. Then, in this case, the vehicle-side device may check up to the ID bit. At this time, it is also preferable that the position of the ID request bit in FIG. 7 and the position of the other (parity or the like) are inverted so that the vehicle side device can use even the parity up to the collation.
As a result, the response signal becomes longer, but the determination of the ID match / mismatch can be performed as usual.

[ID Request for Multiple Portable Devices] In the present embodiment, different ID request bits are assigned to a plurality of portable devices. Therefore, the ID request signal is different for each portable device and cannot be transmitted simultaneously. Therefore, the ID request signal for each portable device is transmitted with its timing shifted. For example, each 200
The transmission is performed every msec, but it is preferable that the timing is shifted by 100 msec for each. Further, a plurality of ID request signals may be sequentially transmitted every 200 msec.

Further, it is also possible to reduce the frequency of sending ID requests to portable devices that are not used very often or not send them at all. It is also preferable that the operation of the operation unit 52 of the portable device restores the transmission of the ID request signal when a response signal from the portable device is received.

"An antenna with a built-in door outer handle" Here, the first transmitting antenna 10 is attached to a door handle (a door outer handle). When the user gets into the vehicle, the user operates the door outer handle to open the door. Therefore, the door outer handle is provided with the first
It is considered effective to attach the transmitting antenna 10.

However, most of the door outer handles are
It swings when you open the door. The first transmitting antenna 10 transmits a request signal to the outside, and is desired to be attached to the outside. Therefore, there is a high possibility that the antenna body is attached to a swinging portion. With such a configuration, there is a movable portion in the routing of the power supply line to the antenna, and the power supply line is required to have durability and waterproofness, resulting in an increase in cost.

Therefore, in this embodiment, as shown in FIG. 8, the main body 70 of the door outer handle is of a fixed type. The door is opened by swinging a lever 72 attached to the main body 70. FIG. 8A shows a state where the door opening operation is not performed, and one end of the lever 72 is separated from the main body 70. On the other hand, FIG.
(B) shows a state in which the door opening operation is being performed, and the lever 72 has moved toward the main body 70 as a whole.

FIG. 8 is a view of the door outer handle as viewed from above, and the upper side in the figure is a vehicle body. An opening 70a is provided in the center of the main body 70, and the lever 72 projects therefrom.
The user can open the door by inserting his hand into the opening 70a and operating the lever 72 toward the front (downward in the figure).

The antenna main body 10a constituting the first transmitting antenna 10 is mounted on a surface facing the outside of the main body 70. Therefore, the lever 72 swings, but the main body 70 does not move. For this reason, a movable portion in the power supply line to the antenna becomes unnecessary.

FIG. 9 shows the oscillator 7 of the first transmitting antenna 10.
4 shows an example in which the antenna body 10a is installed in the door outside the door outer handle, and the antenna body 10a is arranged in the body 70 of the door outer handle. In this case, the oscillator 74 and the antenna main body 10a are connected via the coaxial cable 76 and the balun 78. Therefore, the coaxial cable 76 is inserted from the outside into the main body 70 of the door outer handle, and is connected to the antenna main body 10a via the balun 78. Therefore,
There is no movable part in the coaxial cable 76 regardless of whether it passes through the route A or the route B shown in FIG. 8, and there is no problem such as durability.

As shown in FIG. 10, the oscillator 74 can be installed together with the balun 78 in the main body 70 of the door outer handle. In this case, the oscillator 74 and the balun 78 are arranged on the substrate, and both are arranged on the pattern 8 on the substrate.
Connected by 0. Then, the substrate and the antenna main body 10a are built in the main body 70. In this case, the wire harness for signal supply extends to the substrate and the oscillator 7
4, the movable part can be eliminated in this wire harness, and high durability can be obtained.

An antenna built in the above-mentioned steering wheel
Although a 45 GHz λ / 2 dipole has been described, it can be used as it is for a slot antenna. Further, the same configuration can be adopted even when an antenna having a low frequency of, for example, 125 kHz is used. For example, as shown in FIG.
The ferrite bar antenna 82 may be built in the main body 70. In this case also, connection to the vehicle (wire harness, etc.) is required regardless of whether the antenna amplifier is integrated or separate, but since there is no movable part in the connection route, high reliability can be secured. .

Here, when applied to a smart entry, it is conceivable to mount an antenna not only on the door outer handle but also on the front pillar or the door mirror. However, the final destination when the user opens the door is the door outer handle, and it is considered that installing the first antenna 10 here can easily obtain the most reliable operation.

Further, when a high frequency such as 2.45 GHz is used, the vehicle body functions as a reflector. In particular, when the distance of the main body to the body is λ / 2, the antenna beam shows strong directivity forward. Therefore, power is radiated efficiently in the direction of actual use.

Registration of a new portable device can be easily performed.
