Description

  The present invention does not use a mechanical key (hereinafter referred to as a “mechanical key”) in a vehicle, and performs wireless communication between a vehicle-side CU (Control Unit) and a portable device. If is established, the present invention relates to a vehicle remote control system that can unlock the locking portion.

  Conventionally, a vehicle remote control system includes a portable device that communicates with a vehicle side and a CU that communicates with a portable device in order to enable unlocking of a locking part without using a mechanical key. In general, a mobile device ID (identification information: Identification, hereinafter referred to as “ID”) is registered, and a transmission / reception device for transmitting the ID to a CU is generally provided (for example, a patent). Reference 1).

  In the conventional vehicle remote control system, when the portable device receives a request signal (hereinafter referred to as “request signal”) transmitted in response to a request for unlocking the locking portion, the portable device returns a portable device ID to the CU. On the other hand, the CU collates the received portable device ID with a regular ID registered in the recording unit of the CU in advance, and permits the request on the vehicle side when the portable device ID matches the regular ID. In an emergency such as when the battery of a portable device runs out, a mechanical key is inserted into the key cylinder, and a locking unit such as a door is unlocked by communication between the transponder, which is a mechanical key built-in communication device, and the CU.

Then, the locking part such as a storage part (for example, a glove box or a trunk) can be unlocked only by a mechanical key (hereinafter referred to as “Ballet mode”), and the vehicle is put in a hotel or an automobile repair shop. When depositing, the mechanical key is placed at hand, and only the portable device is deposited with another person, so that the storage unit storing valuables is not unlocked without permission.
Japanese Patent Laid-Open No. 2005-206048

  However, in the conventional vehicle remote control system, when unlocking the lock portion of the bullet mode, the mechanical key must be taken out of the portable device and inserted into the key hole. The convenience that "the locking part can be released simply by attaching to" is impaired.

  The present invention has been made paying attention to the above problem, and the locking part to be in the bullet mode can be unlocked only by wearing the portable device without impairing the safety protection performance in addition to the unlocking by the mechanical key. It is an object of the present invention to provide a vehicular remote control system that can be conveniently used.

In a remote control system for a vehicle provided with a remote control control means capable of unlocking at least the locking part when communication between the portable device and the control unit on the vehicle side is established,
The mechanical key includes a transponder in which identification information of the mechanical key is registered.
The remote controller control means collates the identification information of the portable device and the authorized portable device identification information when the separation distance between the portable device and the transponder is a predetermined value or less, and identifies the mechanical key identification information and the authorized mechanical key identification. The information is collated, and if the result of the collation is that all match, the communication is established, and if either does not fit, the communication is not established.
Therefore, in the vehicle remote control system of the present invention, the identification information of the mechanical key and the identification information of the portable device are collated with the regular identification information by the remote control means, and any identification information is the regular identification information. The lock part is unlocked when it matches, and when any of the identification information does not match the regular identification information, it is not unlocked. In addition, the collation is performed only when the distance between the portable device and the mechanical key is equal to or less than a predetermined value, such as when the mechanical key is bonded to the portable device.
For example, in a conventional vehicle remote control system, the above-mentioned means is not adopted, and the storage part (locking part) for storing valuables is set to a bullet mode that can be unlocked only by a mechanical key. Either the emphasis is placed on the protection or the convenience of the system is emphasized by allowing the portable key to be unlocked in addition to the mechanical key.
On the other hand, the vehicle remote control system of the present invention can unlock the locking portion if the portable device is worn only when the distance between the regular portable device and the regular mechanical key is a predetermined value or less. For example, if a person has a regular mechanical key and a regular portable device for a specific locking part, the locking part can be unlocked (convenience). However, otherwise, the locking part cannot be unlocked (safety protection).

  As a result, it is possible to provide a remote control system for a vehicle that can be unlocked simply by wearing a portable device without impairing safety protection even if the locking portion should be in bullet mode. it can.

FIG. 2 is a flowchart showing a flow of processing (basic processing) on the vehicle side regarding the glove box unlocking processing. The basic process on the vehicle side is the same in the unlocking process of other locking parts.

  In step 21, the glove box request switch 212 is operated, and the process proceeds to step 22.

  In step 22, following the operation of the request switch 212 in step 21, a quest signal is transmitted from the transmission device 220 of the CU 200 to the transmission / reception device 310 of the portable device 300.

  In step 23, following the transmission of the request signal in step 22, if there is a reply from the portable device 300, the process proceeds to step 24. If there is no reply, the next step does not proceed.

  In step 24, following the signal reception in step 23, the received content is confirmed (described later). If a TP-OK signal (to be described later) is received and both conditions that the portable device ID is valid are satisfied, the process proceeds to step 25. If either condition is not satisfied, the process does not proceed to the next step. .

  In step 25, following the confirmation of the received content in step 24, the glove box is unlocked.

  FIG. 3 is a flowchart showing an operation flow in the portable device 300 regarding the glove box unlocking process. The processing on the portable device side is the same in the unlocking processing of other locking units.

In step 31, the portable device 300 is activated, and the process proceeds to step 32.
In step 32, following the activation of the portable device 300 in step 31, reception of a request signal transmitted from the CU 200 is started. That is, it is in a state of waiting for reception.

  In step 33, following the start of reception in step 32, the process proceeds to step 34 when the request signal transmitted from the CU 200 is received, and does not proceed to the next step when the request signal is not received.

  In step 34, following reception of the request signal in step 33, the portable device 300 refers to a signal for confirming the attachment of the mechanical key 100 to the TP 110 provided in the mechanical key 100 (hereinafter referred to as “mechanical key confirmation request signal”). ). If the TP 110 does not receive the mechanical key confirmation request signal, the process does not proceed to the next step.

  In step 35, following the reception of the mechanical key confirmation request signal in TP 110 in step 34, the mechanical key ID registered in advance in TP 110 is transmitted to the portable device 300.

  In step 36, following the transmission of the mechanical key ID by TP 110 in step 35, the portable device 300 receives this mechanical key ID.

  In step 37, following the reception of the mechanical key ID in step 36, it is verified whether or not the mechanical key ID received from the TP 110 matches the regular ID.

  In step 38, following the collation in step 37, if the result of the collation is a match, a match signal (TP-OK signal) is generated, and this TP-OK signal and portable device ID are transmitted to the CU 200 on the vehicle side.

Next, the operation will be described.
In the vehicular remote control system of the present embodiment, when activated (step 31), the portable device 300 stands by until a request signal is received (step 32). When the request switch 212 as the unlock request means is operated (Step 21), the CU 200 transmits a request signal to the portable device 300 via the in-vehicle antenna 224 or 225 as the control unit communication means (Step 22). . When the portable device 300 receives this request signal, it operates as follows.

  When the portable device 300 receives the request signal via the transmission / reception device 310 as a portable communication means, the portable device 300 communicates with the TP 110 via the device 310 and receives the mechanical key ID from the TP 110 (steps 35 and 36). ). At this time, when the distance between the portable device 300 and the transponder 110 (mechanical key 100) is not less than a predetermined value, such as when the mechanical key 100 is not attached to the portable device 300, communication is not performed.

  When the portable device 300 receives the mechanical key ID, the CPU 340 as the collating means collates with the regular ID of the mechanical key registered in advance in the EEP-ROM 330 as the portable recording means (step 37).

If the mechanical key ID transmitted from the TP 110 matches the regular ID as a result of the collation, the CPU 340 generates a TP-OK signal and is registered in advance in the EEP-ROM 330 as portable recording means together with the TP-OK signal. The portable device ID is transmitted to the CU 200 via the transmission device 320 as portable communication means (step 38).
On the other hand, the CU 200 confirms whether or not the TP-OK signal has been received by the CPU 280 as a reception content confirmation unit, and the portable unit having the portable unit ID registered in the EEP-ROM 270 as a control unit recording unit in advance. (Step 24).

  Then, when the TP-OK signal is received and the portable device ID conforms to the regular ID, the CU 200 outputs a signal permitting the unlocking of the glove box, and the unlocking device 240 as the unlocking unit is output. Actuate to unlock the glove box (step 25).

  In the CU 200, when the glove box request switch 212 is not operated (step 21), when there is no reply from the portable device 300 (step 23), the TP-OK signal is not received or the portable device ID is not valid. In the case (step 24), in the portable device 300, when there is no activation request for the portable device 300 (step 31), when the request signal is not received (step 33), when the mechanical key confirmation request signal is not transmitted (step 34), the mechanical key If the ID is not regular (step 37), the process does not proceed from these steps to the next step.

  That is, when the distance between the portable device 300 and the transponder 110 (mechanical key 100) is equal to or smaller than a predetermined value, the portable device 300 communicates with the transponder 110 and receives at least the mechanical key ID (steps 35 and 36). ID verification is performed (step 37). When the received mechanical key ID matches the regular ID registered in the portable device 300 and the portable device ID matches the regular ID registered in the CU 200 (steps 24 and 37), the glove box is unlocked. If either of them does not fit, the glove box is not unlocked (steps 24 and 25).

  In addition, the portable device 300 receives the mechanical key ID from the transponder 110 on the condition that the request signal transmitted from the CU 200 has been received (steps 35 and 36), and collates the mechanical key ID with the normal ID of the mechanical key (step 37). As a result, if it matches, the TP-OK signal and the portable device ID are transmitted to the CU 200 (step 38). Then, the CU 200 receives the conformance signal and collates the transmitted portable device ID with the regular ID registered in the CU 200 (step 24). The glove box is not unlocked (steps 24 and 25) when the mobile device ID is not received or the transmitted portable device ID does not match the regular ID registered in the CU 200.

In addition, the feature of this operation is that the portable device 300 starts receiving a request signal transmitted from the CU 200 in synchronization with the activation of the portable device 300 (step 32).
In addition, the portable device 300 is characterized in that it includes a transmission / reception device 310 as portable communication means that can always communicate with the transponder 110. This is because, in this embodiment, communication between the portable device 300 and the transponder 110 is performed in steps 42 and 43 shown in FIG. 4, but the portable device 300 includes the transmission / reception device 310 and the mechanical key 100 includes the transponder 110. Therefore, the portable device 300 and the transponder 110 can communicate with each other without being limited to the timing of the steps.

Next, the effect will be described.

A control unit communication means for transmitting a request signal for unlocking to the machine 300, receiving a matching signal and a portable machine ID as a reply signal from the portable machine 300, confirming whether or not the matching signal has been received, and the portable machine The received content confirmation means for collating the ID with the regular identification information, and if the conforming signal is confirmed and the collation result of the portable device ID is conforming, the locking unit Since consisted unlocking means for permitting unlocking, the conjunction improve convenience, it is possible to obtain the respective effects of the without greatly changing the conventional vehicle remote control system design. That is, mainly, the portable device 300 is provided with the collation means, and the CU 200 is provided with a check function for checking whether or not the result (conformity signal) is received by the collation means in the reception content confirmation means. Each of the above effects can be obtained.

First, the configuration will be described.
A schematic diagram of the vehicle remote control system of the second embodiment is the same as FIG. Moreover, the flow of the unlocking operation of the glove box in the vehicle-side CU 200 is the same as that in FIG.
FIG. 4 is a flowchart showing an operation flow in the portable device 300 regarding the unlocking process of the glove box, and each step will be described below. Note that the processing of the portable device 300 is the same in the unlocking processing of other locking units.

  In step 41, the mechanical key 100 is attached to the portable device 300, and the process proceeds to step 41. The process does not proceed to the next step until the mechanical key 100 is mounted.

  In step 42, following attachment of the mechanical key 100 in step 41, the TP 110 transmits a mechanical key ID to the portable device 300.

  In step 43, following the transmission of the mechanical key ID in step 42, the portable device 300 receives this mechanical key ID.

  In step 44, following reception of the request signal in step 43, it is verified whether or not the mechanical key ID received from the TP 110 matches the regular ID.

  In step 45, following the collation in step 44, if the result of the collation is a match, a “TP-OK signal” is generated and stored. And portable device 300 does not shift to the next step until it is activated.

  In step 46, following the generation and storage of the TP-OK signal in step 45, if there is a request for activation of the portable device, the process proceeds to step 47.

  In step 47, following the activation of the portable device in step 46, reception of a request signal transmitted from the CU 200 is started.

  In step 48, if the request signal is received following the start of receiving the request signal in step 47, the process proceeds to step 49. The process does not move to the next step until receiving.

  In step 49, following reception of the request signal in step 48, a TP-OK signal and a portable device ID are transmitted to the CU 200. This TP-OK signal is the one stored in step 45.

Next, the operation will be described.
In the vehicle remote control system of the present embodiment, when activated (step 46), the portable device 300 stands by until a request signal is received (step 47). When the request switch 212 as the unlock request means is operated (Step 21), the CU 200 transmits a request signal to the portable device 300 via the in-vehicle antenna 224 or 225 as the control unit communication means (Step 22). . When receiving the request signal, the portable device 300 transmits the portable device ID and the TP-OK signal to the CU 200 (step 49).

  Upon receiving the portable device ID and the TP-OK signal, the CU 200 confirms whether the TP-OK signal is received or not by the CPU 280 as the reception content confirmation unit, and previously stores the portable unit ID in the EEP as the control unit recording unit. -It collates with the regular ID registered in the ROM 270 (step 24).

Then, when the TP-OK signal is received and the portable device ID conforms to the regular ID, the CU 200 outputs a signal permitting the unlocking of the glove box and operates the unlocking device 240 as the unlocking means. The glove box is unlocked (step 25).
On the other hand, the portable device 300 communicates with the TP 110 on the condition that the mechanical key 100 is attached, and receives the mechanical key ID from the TP 110 (steps 42 and 43). At this time, when the distance between the portable device 300 and the transponder 110 (mechanical key 100) is not less than a predetermined value, such as when the mechanical key 100 is not attached to the portable device 300, communication is not performed.

Upon receiving the mechanical key ID, the portable device 300 collates the received mechanical key ID with the normal ID of the mechanical key registered in the EEP-ROM 330 as the portable recording means by the CPU 340 as the collating means (step 44). .
As a result of the collation, when the mechanical key ID transmitted from the TP 110 matches the regular ID, the CPU 340 generates a matching signal and records it in the EEP-ROM 330 as portable recording means (step 45).

Then, when the portable device 300 is activated (step 46), the operations after step 47 are started.
In the portable device 300, when the mechanical key is not attached (step 41), when the mechanical key ID is not valid (step 44), or when there is no activation request for the portable device 300 (step 46), the process proceeds from these steps to the next step. Do not migrate.

  That is, when the distance between the portable device 300 and the transponder 110 (mechanical key 100) is equal to or smaller than a predetermined value, the portable device 300 communicates with the transponder 110 and receives at least the mechanical key ID (steps 42 and 43). The mechanical key ID is collated (step 44). As a result of this collation, when the received mechanical key ID matches the regular ID registered in the portable device 300 and the portable device ID matches the regular ID registered in the CU 200, the glove box is unlocked. If either of them does not fit, the glove box is not unlocked (step 24).

  In addition, on the condition that the mechanical key 100 is attached, the portable device 300 communicates with the TP 110, receives the mechanical key ID from the TP 110 (steps 42 and 43), and the received mechanical key ID is registered in the portable device 300 in advance. The matching TP-OK signal is stored (step 45), and if the request signal transmitted from the CU 200 is received, the matching signal and the portable device are checked. The ID is transmitted to the CU 200 (step 49). Then, when the CU 200 receives the conformance signal and collates the transmitted portable device ID with the regular ID registered in the CU 200 (step 24), if it matches, the glove box is unlocked (step 25). The glove box is not unlocked when the matching signal is not received or the transmitted portable device ID does not match the regular ID registered in the CU 200.

  In addition, the feature of this operation is that the portable device 300 starts receiving a request signal transmitted from the CU 200 in synchronization with the activation of the portable device 300 (step 47).

In addition, the portable device 300 is characterized in that it includes a transmission / reception device 310 as portable communication means that can always communicate with the transponder 110. This is because, in the present embodiment, the communication between the portable device 300 and the transponder 110 is performed in steps 42 and 43, but the portable device 300 includes the transmission / reception device 310, and the mechanical key 100 includes the transponder 110. The portable device 300 and the transponder 110 can communicate not only with the timing of the step.
Next, the effect will be described.

  According to the vehicle remote control system of the present embodiment, the following effects can be obtained in addition to the effects listed in the first embodiment.

Are matched, the TP-OK signal is stored, and the matching signal and the portable device ID are transmitted to the CU 200 on condition that the request signal transmitted from the CU 200 is received. Then, when the CU 200 receives the conformance signal and collates the transmitted portable device ID with the regular ID registered in the CU 200, if it conforms, the glove box is unlocked and does not receive the conformance signal. Since the glove box is not unlocked when the transmitted portable device ID does not match the regular ID registered in the CU 200, the convenience of the portable device 300 and the response of the CU 200 are improved. . Further, whether or not the mechanical key 100 is authorized can be confirmed not only in a state where the portable device 300 is activated.

Further, the collation of these IDs can be achieved by third means in addition to the portable device 300 and the CU 200.

Further, in communication between the portable device 300 and the TP 100, for example, sensing whether the mechanical key 100 is attached to the portable device 300, such as turning on the lighting device if the mechanical key 100 is not attached to the portable device 300. It is possible to provide means that facilitates the above. In this way, the convenience of the vehicle remote control system is improved, and the safety protection performance such as loss of the mechanical key 100 and theft prevention is further improved.
When the mechanical key ID transmitted from the TP 110 matches the regular ID registered in the portable device 300 as a result of the collation in the portable device 300, only the portable device ID is transmitted to the CU 200. In the CU 200, this portable device ID is transmitted. May match the regular ID registered in CU200, and the glove box may be unlocked. If it does in this way, the structure and processing method of this remote control system for vehicles can be simplified with the said convenience improvement.

  In the above embodiment, the present invention is applied to the unlocking of the glove box. However, the present invention is not limited to this, and can be applied to the unlocking of a trunk or the like. Furthermore, the present invention is not limited to application to a vehicle remote control system, and can be applied to unlocking means for other uses as long as it has a locking principle.
