Next, each vehicle receives the portable device IDH1 transmitted by the portable device ID transmitting means 18 by the portable device ID receiving means 3 of the vehicle side transmitting / receiving means 4, and the received portable device IDH1 is stored in the vehicle memory 1. The portable device ID authenticating means 5 provided in the vehicle-side microcomputer 8 authenticates whether or not it matches the ID registered in (step 6).
In the case of this example, since only the vehicle memory 1 of the vehicle A owns the portable device IDH1, only the vehicle A can authenticate the portable device IDH1.
The vehicle-side microcomputer 8 of each vehicle is provided with vehicle control means 7 for operating the door lock driving means 6 of the vehicle based on the authentication result by the portable device ID authentication means 5.
Therefore, in the case of the first embodiment, only the vehicle A can be successfully authenticated by the portable device ID authenticating means 5, and as a result, the vehicle provided in the vehicle-side microcomputer 8 of the vehicle A The control means 7 operates the door key driving means 6 to unlock the door lock of the vehicle A (step 7).

As described above, if the user sets a desired vehicle in advance using the selection unit 11, the user can open the door only for the desired vehicle without having to operate the portable device each time.
Therefore, according to this invention, it is a keyless system which performs what is called a passive type operation | movement, Comprising: Compared with a prior art example, it is safer and can provide the keyless system excellent in convenience.
In the first embodiment, the selected ID is temporarily stored in the authentication memory 14, but it is not always necessary. For example, the selected portable device memory 10-1 to 3 is flagged and the flag is raised. Authentication may be performed with the memory.

Next, Embodiment 2 of the present invention will be described.
According to the second embodiment, as shown in FIG. 3, in addition to the selection means 11, the portable device further includes an active operation switch means 20 that instructs the desired vehicle to select an active action.
Accordingly, it is possible to provide a keyless system that can perform the same operation as the active type in addition to the passive type operation described above.

  The active operation switch means 20 is a door unlocking (locking) switch for active operation. By operating the active operation switch means 20, the portable device can be used regardless of the authentication by the vehicle ID authentication means 13, The portable device ID and the active operation command code stored in the authentication memory 14 are transmitted to the vehicle-side transmitting / receiving means 4.

  In the second embodiment, when the user selects the vehicle 1 as a desired vehicle among a plurality of vehicles (vehicle A, vehicle B, vehicle C) that can be controlled by the portable device and operates the active operation switch means 20. Will be described with reference to the flowchart shown in FIG.

First, the user selects the portable device memory 10-1 of the vehicle A by the selection unit 11 of the portable device (step 1).
By this operation, the portable device side microcomputer 12 reads the vehicle IDV1 and the portable device IDH1 from the portable device memory 10-1 corresponding to the vehicle A, and the vehicle IDV1 and the portable device IDH1 are stored in the authentication memory 14 respectively. Write as ID15 and authentication portable device ID16 (step 2).
By the operation of the selection means 11, the vehicle A is registered in advance as a vehicle that is normally used.

In this state, a user who desires an active operation operates a door unlocking (locking) switch of the active operation switch means 20 provided in the portable device (step 3).
By this operation, the portable device calls the active operation instruction code from the portable device side microcomputer 12, and carries the active operation instruction code together with the authentication portable device ID15 (IDH1) stored in the authentication memory 14 of the portable device. The machine side transmission / reception means 19 transmits to the vehicle side transmission / reception means 4 (step 4).
On the other hand, each vehicle receives the portable device IDH1 transmitted from the portable device by the portable device ID receiving means 3 of the vehicle-side transmitting / receiving means 4, and the received portable device IDH1 is registered in each vehicle memory 1. It is authenticated by the portable device ID authenticating means 5 included in the vehicle-side microcomputer 8 whether or not it matches the portable device ID (step 5).
In this example, since only the vehicle memory 1 of the vehicle A has the portable device IDH1, only the vehicle A can authenticate the portable device IDH1, and as a result, the vehicle-side microcomputer 8 of the vehicle A The vehicle control means 7 operates the door key drive means 6 to unlock the door lock of the vehicle A (step 6).
Thus, by using the active operation switch means 20, it is possible to reliably specify only the vehicle selected by the selection means 11 of the portable device and control the vehicle control means 7 of the vehicle.

In Embodiment 2 described above, the portable device ID 16 of the authentication memory 14 and the command code of the active operation are transmitted in Step 4 by the switch operation of the active operation switch means 20. The vehicle ID stored in the memory 14 can also be transmitted at the same time, and correspondingly, in step 5, each vehicle can be configured to authenticate the vehicle ID 15 together with the portable device ID 16. If comprised in this way, even if it is a case where portable machine ID is registered into a some vehicle, for example, since only the selected vehicle operate | moves, a vehicle can be specified more reliably. In the first and second embodiments, the signal transmitted from the portable device is a different signal. However, the transmission signal of the first embodiment may be the same as that of the second embodiment.
Also in the second embodiment, the selected ID is once stored and transmitted in the authentication memory 14, but this is not always necessary. For example, the selected portable device memory 10-1 to 3 is flagged and the flag is set. It is also possible to transmit the memory in which is standing.

  As described above, the portable device further includes the active operation switch means 20 for selecting the active operation, so that it is possible to provide a keyless system that can perform the same operation as the active type according to the user's wish, and is more secure. It is possible to select a keyless system that excels in performance.

Next, an ID registration method at the time of registration according to the present invention will be described.
According to the keyless system of the present invention, as shown in FIG. 3, each vehicle further includes registration operation mode setting means 21 for registering the vehicle in the portable device in advance as a desired vehicle. When the vehicle set in the registration operation mode by the registration operation mode setting means 21 receives the command code of the active operation sent from the portable device side microcomputer 12 by the operation of the active operation switch means 20 of the portable device, the portable device The portable device ID transmitted from the mobile phone is written in the vehicle memory 1 of the vehicle.
In addition, the vehicle set in the registration operation mode by the registration operation mode setting means 21 transmits the vehicle ID stored in the vehicle memory 1 of the vehicle to the portable device and transmits the vehicle ID to the portable device. An instruction code for requesting registration in the portable device memories 10-1 to 3 is transmitted to the portable device.
Therefore, the user selects the vehicle B as a desired vehicle among a plurality of vehicles (vehicle A, vehicle B, vehicle C) managed by the portable device, and operates the registered operation mode setting means 21 to operate the vehicle. The operation when B is registered in the portable device will be described with reference to the flowchart shown in FIG.

  In order to register the vehicle IDV2 stored in the vehicle memory 2 of the vehicle B in the portable device by an operation from the vehicle B, first, the user registers in the communication control means 9 of the desired vehicle B. The operation mode setting means is operated 21 to set the communication control means 9 of the vehicle B to the registered operation mode (step 1).

At the time when the registration operation mode is set, the portable device stores IDH1 of the portable device memory 10-1 in the authentication memory 14 as the portable authentication device ID 16 for authentication. That is, the portable device 10-1 is selected by the operation of the selection means 11 (step 2), and the vehicle IDV1 and the portable device IDH1 are read from the selected portable device memory 10-1, and this is the authentication. (Step 3), (Step 4).
In such a state, the user next operates the active operation switch means 20 provided in the portable device (step 5).
As a result of this operation, the instruction code for the active operation is transmitted by the portable device side transmission / reception means 19 together with the portable device IDH1 stored in the authentication memory 14 in the same manner as the operation of step 4 in the flowchart shown in FIG. It transmits to the vehicle side transmission / reception means 4 (step 6).

On the other hand, the vehicle B to be registered receives the command code for the active operation together with the portable device IDH1 transmitted in step 6 by the vehicle-side transmitting / receiving means 4 (step 7).
Here, since the vehicle B is set to the registration operation mode, when the vehicle B receives the command code of the active operation, the received portable device IDH1 is written in its own vehicle memory 2 (step 8). . Therefore, vehicle IDV2 and portable machine IDH1 are memorize | stored in the vehicle memory 2 of the vehicle B to register.
Note that the vehicle set in the registration operation mode is configured not to perform the unlocking (locking) operation of the door even when the command code of the active operation is received by being set in the registration operation mode. .
Here, as described above, the vehicle set in the registration operation mode requests registration of the vehicle ID in the portable device memories 10-1 to 10-3 together with the vehicle ID stored in the vehicle memory of the vehicle. The instruction code to be transmitted is transmitted to the portable device. Accordingly, the vehicle B transmits the vehicle IDV2 stored in the vehicle memory 1 and a command code requesting the portable device to register the vehicle IDV2 to the portable device (step 9).

The portable device receives the vehicle IDV2 and the command code for requesting registration transmitted by the vehicle in step 9 by the portable device transmitting / receiving means 19 (step 10).
The portable device is configured to write the portable device ID transmitted from the vehicle into the portable device memory 10-1 selected by the selection means 11 by receiving the instruction code. Therefore, the portable device writes the vehicle IDV2 received in Step 10 in the portable device memory 10-1 selected in Step 2 (Step 11).
As described above, the vehicle IDV2 and the portable device IDH1 are stored in the portable device memory 10-1 selected by the selection unit 11.
Therefore, the same ID is registered in both the portable device memory 10-1 and the vehicle ID and portable device ID stored in the vehicle memory 1 of the vehicle to be registered.

  Thus, the registration operation from the vehicle side can forcibly register the ID of the vehicle to be registered in the memory selected by the portable device, so the communication control means 9 of the desired vehicle is set to the registration operation mode. By simply operating the active operation switch means 20 of the portable device, a desired vehicle can be set in the portable device. In addition, since the setting operation can be performed from the desired vehicle side without the operation of the selection unit 11 of the portable device, the desired vehicle can be selected more safely and reliably.

Next, a third embodiment of the present invention will be described.
As described above, in order to set a desired vehicle in advance by the selection unit 11 of the portable device, it can be performed by a switch operation of the selection unit 11, but the ID of the vehicle used by the user last time is the authentication of the portable device. If it is stored in the memory 14 as it is, and there is no selection of a specific vehicle by the operation of the selection means 11, it can be performed by selecting it as an authentication ID as it is.
Alternatively, the ID of the vehicle used by the user last time is stored in the portable device side microcomputer 12, and if a specific vehicle is not selected by the operation of the selection unit 11, it is output to the authentication memory 14 at the time of authentication. It can also be done.
In this way, the selection unit 11 is configured to select the vehicle ID and the portable device ID corresponding to the vehicle selected most recently, so that the selection unit 11 is operated every time the user uses the portable device. This saves you time and effort.

Next, a fourth embodiment of the present invention will be described.
The above selection means 11 may be configured to calculate the selection frequency of the vehicle selected in the past by the portable device side microcomputer 12 and select a vehicle having a high selection frequency based on the calculation result. This saves the user from having to operate the selection means 11 every time he / she uses the portable device.

  In order to determine a vehicle having a high selection frequency, for example, a selection frequency number register corresponding to the number of vehicles managed by the portable device is prepared in the portable device-side microcomputer 12, and each vehicle is selected. The ID having the largest value in the register is determined as having a high selection frequency at that time.

More specifically, for example, if the portable device can select three vehicles, three registers (R1, R2, R3) are prepared, R1 is a selection frequency number register of IDV1, and R2 is IDV2. The selection frequency number register, R3, is the IDV3 selection frequency number register. The initial value of each register is set to 0, and the stored value of the register is updated based on the following calculation formula only when collation with the vehicle is established.
Calculation formula R1 after update = (R1 before update) * α + (when the ID for which collation is established is ID1 = 1, other than IDV1 = 0) * β
R2 after update = (R2 before update) * α + (when the ID that is verified is ID2 = 1, other than IDV2 = 0) * β
R3 after update = (R3 before update) * α + (when the ID for which verification is established is ID3 = 1, other than IDV3 = 0) * β
Here, α = weighting coefficient of past number of matching (coefficient multiplied by past value), β = weighting coefficient of one matching (coefficient multiplied by current value).
However, 0 <β <α <1 (example α = 0.9 β = 0.1)
In this way, the influence α set in the past is reduced by, for example, 0.9, and the latest influence β is multiplied by, for example, 0.1, so that the past selection frequency can be reduced. It is possible to set the number of selection frequencies in consideration of the current selection in a well-balanced manner. As described above, α = 0.9 and β = 0.1 are optimal for setting such a balance. However, as long as 0 <β <α <1, a suitable value is obtained. Can take a value.
In this way, the number of selection frequencies is accumulated in the registers corresponding to the respective vehicles, and the ID having the largest register value at that time is selected as the one having the highest selection frequency.
With this configuration, it is possible to detect the selection frequency simply by preparing registers corresponding to the number of vehicles, and there is no need to prepare a large number of registers. In addition, since the past selection frequency and the current selection can be considered in a balanced manner, a more realistic selection frequency can be set.

Next, a fifth embodiment of the present invention will be described.
The selection means 11 described above can be configured to select the vehicle ID that is initially set in the authentication memory 14 of the portable device. Thus, since the specific vehicle initially set by the user is always selected, the selection means 11 only needs to be operated only when a new vehicle needs to be newly set. It is possible to save time and effort to operate the selection means 11 each time.
