[Example 1]
(1) Overall Configuration As shown in FIG. 1, the vehicle control system 1 of the present embodiment is a system that includes a plurality of in-vehicle devices 11 mounted on a plurality of vehicles 3 and portable devices 13. It has a remote keyless entry function that transmits a signal to the vehicle-mounted device 11 by wireless communication in accordance with an input operation to lock or unlock the door. And the vehicle control system 1 of a present Example will transmit a signal with respect to the several vehicle 3, and will perform the lock or unlock of a door, if predetermined | prescribed input operation is performed to the portable device 13. As shown in FIG. 1, a plurality of in-vehicle devices 11 are mounted on a plurality of vehicles 3 on a one-to-one basis.

Note that the vehicle control system 1 also has a wireless authentication function (so-called smart entry and start system function) that allows the engine to be started and the door locked or unlocked without using a mechanical key.

As shown in FIG. 2, the in-vehicle device 11 has a verification Electronic Control Unit (ECU) 21. The verification ECU 21 is configured around a known microcomputer including a CPU 22a, a ROM 22b, a RAM 22c that control the function of the verification ECU 21, an input / output interface (not shown), a bus line that connects these configurations, and the like.

The CPU 22a executes operation control as a wireless authentication system in accordance with an application program read from the ROM 22b. The ROM 22b stores a unique authentication code assigned to the in-vehicle device 11.

The verification ECU 21 detects a transmitter 23 that transmits a transmission request signal to a predetermined detection area inside and outside the vehicle 3, a receiver 24 that receives a signal wirelessly transmitted from the portable device 13, and an open / closed state of the door. A door opening / closing detection switch 25, a door lock sensor 26 for detecting a locked / unlocked state of the door, and a door lock control device 28 for driving and controlling a door lock motor 27 for locking and unlocking the door of the vehicle. Is connected. The door lock control device 28 is an example of a predetermined device and a locking device in the present disclosure.

The transmitter 23 transmits predetermined data by frequency-modulating (FM) or amplitude-modulating (AM) a radio wave having a low-frequency (LF) band radio wave (for example, a radio wave in the vicinity of 134 kHz) as a carrier wave. The receiver 24 is configured to be able to receive UHF band radio waves in a preset range.

On the other hand, the portable device 13 receives a CPU 31 that controls the function of the portable device 13 and a signal transmitted from the transmitter 23 through an antenna (not shown) and inputs data included in the signal to the CPU 31. 32 and a transmission unit 33 that transmits a transmission signal including data output from the CPU 31 from a transmission antenna (not shown).

The portable device 13 includes an operation button group 34 that receives an input operation for locking and unlocking the door of the vehicle, and a storage unit 35 that stores various data.

Here, the transmission unit 33 transmits predetermined data by performing FM modulation or AM modulation on a radio wave having a predetermined response frequency as a carrier wave. As a response frequency of the transmission unit 33, for example, a radio wave within a range of 300 to 400 MHz which is a Radio Frequency (RF) band in an Ultra High Frequency (UHF) band is set.

The operation button group 34 includes a plurality of buttons, and can accept various input operations by the user. As an example, a lock button for locking the door, an unlock button for unlocking the door, a changeover switch for switching the vehicle 3 to be operated, and the like are provided.

The operation button group 34 includes an all-vehicle lock button 34a and an all-vehicle unlock button 34b (hereinafter, collectively referred to as all-vehicle operation buttons). By operating these buttons, all the plurality of vehicles 3 can be operated. The door can be locked and unlocked. The all-car lock button 34a and the all-car unlock button 34b are examples of the input unit in the present disclosure.

The operation button group 34 may be configured as a touch panel including a display such as a liquid crystal. In that case, it is possible to display a virtual button on the display and allow the user to perform an operation.

The storage unit 35 stores authentication codes of the plurality of in-vehicle devices 11 mounted on the plurality of vehicles 3. As an example, the storage unit 35 may be a flash memory that is electrically rewritable. The storage unit 35 is an example of an authentication code storage unit in the present disclosure.

The vehicle control system 1 configured as described above performs remote keyless entry control according to the operation of the operation button group 34 of the portable device 13 by the user. In addition, wireless authentication is performed by performing communication for determining whether or not the portable device 13 is a registered electronic key every time the in-vehicle device 11 is set for a certain period or a predetermined event such as door opening / closing occurs. Realize the function.

Since this vehicle control system 1 is characterized by remote keyless entry control when all the vehicle operation buttons are operated, the control will be described below.

(2) Remote keyless entry control in the vehicle control system 1 The vehicle control system 1 is configured such that when a user operates all the vehicle operation buttons provided in the operation button group 34 of the mobile device 13, the vehicle registered in the mobile device 13 is registered. 3 Lock or unlock all doors. The vehicle 3 registered in the portable device 13 is a vehicle 3 equipped with the in-vehicle device 11 corresponding to the authentication code stored in the storage unit 35.

(2-1) Processing by Portable Device 13 A processing procedure of signal transmission processing executed by the CPU 31 of the portable device 13 will be described based on the flowchart shown in FIG.

First, in S1 of this process, it is determined whether or not an input operation to all vehicle operation buttons has been accepted. If there is no input operation (S1: NO), S1 is executed again. That is, it waits until there is an input operation on all the vehicle operation buttons. If there is an input operation (S1: YES), the process proceeds to S2.

In subsequent S2, a transmission vehicle to which a signal is to be transmitted is determined. Here, one of the plurality of authentication codes stored in the storage unit 35 is selected. A flag that can determine whether or not the authentication code has been selected can be attached to the authentication code. In S2, one of the authentication codes that have not been selected is selected. A selected flag is attached to the selected authentication code.

In the next S3, the authentication code and the control command are transmitted to the in-vehicle device 11. The control command is a command for causing the vehicle-mounted device 11 to lock or unlock the door, and the content of the command is determined by which of the all-car lock button 34a and the all-car unlock button 34b is input.

In the next S4, it is determined whether there is an untransmitted vehicle. Here, it is checked whether or not there is an authentication code without a selected flag. If there is an authentication code without a selected flag, it is determined that there is an untransmitted vehicle (S4: YES), and the process returns to S2. On the other hand, if there is no authentication code without a selected flag (S4: NO), it is determined that there is no untransmitted vehicle, and this process ends.

Thus, in this process, the CPU 31 repeats the process of S3 until there is no untransmitted vehicle. The CPU 31 that performs the process of S3 and the transmission unit 33 that transmits a signal are examples of the signal transmission unit in the present disclosure.

(2-2) Processing by the in-vehicle device 11 A processing procedure of door lock processing executed by the CPU 22a of the in-vehicle device 11 will be described based on the flowchart shown in FIG. This process is started when a transmission signal is received from the portable device 13.

First, in S11 of this process, it is determined whether or not the authentication is OK by comparing the authentication code transmitted from the portable device 13 in S3 of FIG. 3 with the authentication code assigned to the in-vehicle device 11. If the authentication is not OK (S11: NO), that is, if the authentication codes do not match, this process ends. Note that the matching of the authentication codes is not limited to a case where both authentication codes completely match, and includes, for example, a case where both authentication codes satisfy a pre-registered correspondence.

On the other hand, if the authentication is OK (S11: YES), that is, if the authentication codes match, the door is locked or unlocked according to the control command included in the transmission signal (S12). The CPU 22a that performs the process of S12 is an example of a control unit in the present disclosure. After this S12, this process ends.

(3) Effect In the vehicle control system 1 configured as described above, the user performs an input operation on all the vehicle operation buttons of the operation button group 34, so that all the vehicles 3 registered in the portable device 13 are operated. Door lock or unlock can be executed. This eliminates the need for the user to select the target vehicle 3 to be operated by operating the portable device 13, thereby improving the convenience of vehicle control.

For example, when there is a vehicle 3 that wants to lock the door, it is not necessary to set or switch the operation target to that vehicle, so the operation procedure can be reduced. In addition, it is possible to suppress the occurrence of problems such as no longer knowing which vehicle 3 should be switched to, or accidentally switching the operation target to another vehicle 3.

In the present embodiment, a configuration in which door locking or unlocking is executed for all vehicles 3 registered in the portable device 13 is illustrated, but the present disclosure is configured for all vehicles 3. It is not limited. For example, it may be configured to target a plurality of vehicles 3 selected in advance by the user, or may be configured to target all vehicles 3 existing within a predetermined period or within a predetermined distance. That is, it is good also as a structure which performs a door lock or unlocking with respect to the control object vehicle group containing the two or more vehicles 3 set as a control object by the user among all the vehicles 3. FIG.

[Example 2]
(1) Overall Configuration Since the vehicle control system 41 of the second embodiment is partially different from the vehicle control system 1 of the first embodiment, the differences will be mainly described and vehicle control will be described. A description of the same points as in the system 1 will be omitted.

In the vehicle control system 41 of the present embodiment, the doors of the plurality of vehicles 3 are locked or unlocked based on a predetermined input operation by the user. Therefore, as shown in FIG. 5, when the vehicle control system 41 transmits a signal to one vehicle 3, the vehicle 3 receiving the signal transmits a signal to the other vehicle 3, and further receives the signal. Control is performed such that the vehicle 3 that has been transmitted transmits a signal to another vehicle 3.

The vehicle control system 41 includes an in-vehicle device 43 and a portable device 45 as shown in FIG. The in-vehicle device 43 is different from the in-vehicle device 11 of the first embodiment in that a bidirectional communication device 47 is provided.

The bi-directional communication device 47 is a device that performs bi-directional wireless communication with other in-vehicle devices 43 and is connected to the verification ECU 49. As the bidirectional communication device 47, for example, a Bluetooth (Bluetooth®) device, a wireless LAN (Local Area Network) device, or the like can be used. The bidirectional communication device 47 is an example of an inter-vehicle communication unit in the present disclosure.

The basic structure of the portable device 45 is the same as that of the portable device 13 of the first embodiment, but the processing contents by the CPU 53 are different.

(2) Remote keyless entry control in the vehicle control system 41 As in the vehicle control system 1 of the first embodiment, the vehicle control system 41 is operated by all the vehicle operation buttons arranged on the operation button group 34 of the portable device 45 by the user. Then, the doors of all the vehicles 3 registered in the portable device 45 are locked or unlocked.

(2-1) Processing by Mobile Device 45 A processing procedure of signal transmission processing executed by the CPU 53 of the mobile device 45 will be described based on the flowchart shown in FIG.

First, in S31 of this process, it is determined whether or not an input operation to all the vehicle operation buttons has been accepted. If there is no input operation (S31: NO), S31 is executed again. That is, it waits until there is an input operation on all the vehicle operation buttons. If there is an input operation (S31: YES), the process proceeds to S32.

In subsequent S32, a transmission vehicle to which a signal is to be transmitted is determined. Here, one of the plurality of authentication codes stored in the storage unit 35 is selected. This authentication code is set as a first authentication code. The transmission vehicle selection method, that is, the first authentication code selection method is not particularly limited. For example, the vehicle 3 that has finally performed an operation such as a door lock from the portable device 45 or the vehicle 3 that is closest to the portable device 45 can be determined as the transmission vehicle.

In the next S33, all authentication codes and control commands held by the portable device 45 are transmitted to the in-vehicle device 43. In the present embodiment, the in-vehicle device 43 that receives these signals transmitted from the portable device 45 is referred to as a first in-vehicle device 43 for convenience.

All the above-mentioned authentication codes are a plurality of authentication codes stored in the storage unit 35. Among these, the first authentication code is transmitted as a signal for collating with the authentication code of the first in-vehicle device 43. The other authentication codes except the first authentication code are simply transmitted as authentication code data that is data indicating the information of the authentication code. Information of one or more authentication codes is shown in the authentication code data.

Further, the above-described control commands include a first control command and a second control command. The first control command is a command for locking or unlocking the door, and the second control command is a command for causing the first in-vehicle device 43 to transmit a predetermined signal to another in-vehicle device 43. It is. Details of the signal transmitted here will be described later. Note that the CPU 53 that performs the processing of S33 and the transmission unit 33 that transmits a signal are examples of the signal transmission unit in the present disclosure. After S33, this process ends.

(2-2) Processing by the in-vehicle device 43 (2-2-1) First door lock processing The processing procedure of the first door lock processing executed by the CPU 49a of the verification ECU 49 of the in-vehicle device 43 is shown in the flowchart of FIG. This will be explained based on. This process is started when a signal is received from the portable device 13 and is executed in the first in-vehicle device 43.

First, in S41 of this process, it is determined whether or not the authentication is OK by comparing the first authentication code transmitted from the portable device 45 with the authentication code assigned to the in-vehicle device 43. If the authentication is not OK (S41: NO), this process ends.

On the other hand, if the authentication is OK (S41: YES), the door is locked or unlocked according to the first control command included in the transmission signal (S42). After S42, the process proceeds to S43. S43 to S45 are processes according to the second control command.

In subsequent S43, it is determined whether there is information on other vehicles. The other vehicle information is authentication data corresponding to the in-vehicle devices 43 other than the first in-vehicle device 43. If authentication code data is included in the transmission signal transmitted in S33, it is determined that there is information on another vehicle. If there is no information on other vehicles (S43: NO), this process is terminated. On the other hand, if there is information on another vehicle (S43: YES), the process proceeds to S44.

In the next S44, a transmission vehicle to which a signal is to be transmitted is determined. Here, one of the authentication codes indicated in the authentication code data transmitted in S33 is selected. This authentication code is set as a second authentication code. The transmission vehicle selection method, that is, the second authentication code selection method is not particularly limited. The in-vehicle device 43 to which the second authentication code is assigned is referred to as a second in-vehicle device 43 for convenience.

In subsequent S45, the received authentication code excluding the host vehicle and the control command are transmitted to the second vehicle-mounted device 43. Here, the received authentication code excluding the host vehicle is an authentication code excluding the first authentication code among the authentication codes stored in the storage unit 35.

Among the authentication codes transmitted to the second vehicle-mounted device 43, the second authentication code is transmitted as a signal for checking with the authentication code of the second vehicle-mounted device 43. Further, other authentication codes other than the first authentication code and the second authentication code are transmitted as authentication code data. If there is no other authentication code, the authentication code data is not transmitted.

Further, the control command transmitted to the second vehicle-mounted device 43 includes the first control command and the second control command described above. However, when the authentication code data is not transmitted, the second control command is not transmitted. After S45, this process ends. The CPU 49a that performs the processes of S42 and S45 is an example of a first control unit in the present disclosure.

(2-2-2) Second Door Lock Process The procedure of the second door lock process executed by the CPU 49a included in the verification ECU 49 of the in-vehicle device 43 will be described based on the flowchart shown in FIG.

This process is a process executed by the second vehicle-mounted device 43, and is started when a signal is received from the first vehicle-mounted device 43.

First, in S51 of this process, it is determined whether or not the authentication is OK by comparing the second authentication code transmitted from the first vehicle-mounted device 43 with the authentication code assigned to the second vehicle-mounted device 43. If the authentication is not OK (S51: NO), this process ends.

On the other hand, if the authentication is OK (S51: YES), the door is locked or unlocked according to the first control command (S52). After S52, the process proceeds to S53. The CPU 49a that performs the process of S52 is an example of a second control unit in the present disclosure.

In subsequent S53, it is determined whether there is information on other vehicles. The other vehicle information is authentication data corresponding to the vehicle-mounted device 43 other than the first and second vehicle-mounted devices 43. If the authentication code data is included in the signal transmitted in S45, it is determined that there is information on another vehicle. If there is no information on other vehicles (S53: NO), this process is terminated. On the other hand, if there is information on another vehicle (S53: YES), the process proceeds to S54.

In the next S54, a transmission vehicle to which a signal is to be transmitted is determined. Here, one of the authentication codes indicated in the authentication code data transmitted in S45 is selected. The authentication code selected here is assumed to be a third authentication code. The method for selecting the transmission vehicle, that is, the method for selecting the third authentication code is not particularly limited. The in-vehicle device 43 to which the third authentication code is assigned is referred to as a third in-vehicle device 43 for convenience.

If the authentication code data is not included in the signal transmitted in S45, the processes in S54 and S55 are not performed and the process ends.

In subsequent S55, the received authentication code excluding the host vehicle and the control command are transmitted to the third vehicle-mounted device 43. Here, the received authentication code excluding the host vehicle is an authentication code excluding the first authentication code and the second authentication code among the authentication codes stored in the storage unit 35.

Among the authentication codes transmitted to the third vehicle-mounted device 43, the third authentication code is transmitted as a signal for collating with the authentication code of the third vehicle-mounted device 43. Further, other authentication codes other than the first to third authentication codes are transmitted as authentication code data. If there is no other authentication code, the authentication code data is not transmitted.

The control command transmitted to the third vehicle-mounted device 43 includes the first control command and the second control command described above. However, when the authentication code data is not transmitted, the second control command is not transmitted. After S55, this process ends.

By the way, the first to third vehicle-mounted devices 43 are only capable of performing similar control and processing, with the notation changed for ease of understanding.

In addition, the first to third authentication codes are the same kind of codes because only the numbers are changed for convenience of explanation because the in-vehicle device 43 that is the processing subject is different. Accordingly, the third in-vehicle device 43 that has transmitted the signal in S55 executes the second door lock process in the same manner as the second in-vehicle device 43, and further performs the process of S55 for another in-vehicle device 43. Can be executed.

(3) Effects The vehicle control system 41 configured as described above is configured to control a plurality of vehicles 3 when the user performs an input operation on all the vehicle operation buttons, similarly to the vehicle control system 1 of the first embodiment. The door can be locked or unlocked, and the convenience for the user is improved.

In the present embodiment, as in the first embodiment, the object such as the door lock is not limited to the configuration in which all the vehicles 3 registered in the portable device 45 are used, and the vehicle 3 may be processed in a limited manner. .

Alternatively, the first in-vehicle device 43 may not transmit the second control command to the second in-vehicle device 43, but may transmit only the first control command together with the authentication code. In addition, each signal may be transmitted from the first vehicle-mounted device 43 to the plurality of second vehicle-mounted devices 43.

Further, the portable device 45 may be configured to transmit the authentication code and the control command to the plurality of in-vehicle devices 43 in S33 of FIG. In that case, the in-vehicle device 43 may transmit these signals a plurality of times from the portable device 45 and other in-vehicle devices 43, or from a plurality of different in-vehicle devices 43. The received signal can be discarded, and the signal transmission to the other in-vehicle device 43 can be prevented from being executed.

[Example 3]
(1) Overall Configuration Since the vehicle control system 61 of the third embodiment is partially different from the vehicle control system 1 of the first embodiment, the differences will be mainly described and vehicle control will be described. A description of the same points as in the system 1 will be omitted.

FIG. 10 shows the configuration of the vehicle control system 61 of this embodiment. The in-vehicle device 11 has the same configuration as that of the first embodiment.

The portable device 63 stores the control history of the vehicle 3 by the portable device 63 in addition to the information of the authentication code in the storage unit 65. When the CPU 67 controls the door 3 to be locked or unlocked with respect to any of the vehicles 3 by the portable device 63, the storage unit 65 associates the control content and the vehicle 3 to be operated with the operation time. Remember me. The storage unit 65 is an example of an authentication code storage unit and a history storage unit in the present disclosure.

In addition to the lock button, the unlock button, and the changeover switch, the portable device 63 includes a designated vehicle lock button 69a that locks the door of the vehicle 3 operated immediately before, and the vehicle 3 operated just before. A designated vehicle unlock button 69b (hereinafter collectively referred to as a designated vehicle operation button) is provided. The designated vehicle lock button 69a and the designated vehicle unlock button 69b are examples of the input unit in the present disclosure.

(2) Remote keyless entry control in the vehicle control system 61 The vehicle control system 61 is configured such that when a designated vehicle operation button arranged on the operation button group 69 of the portable device 63 is operated by the user, the vehicle registered in the portable device 63 3, lock or unlock control of the door of the vehicle 3 selected based on the history information is executed. In other words, the vehicle 3 registered in the portable device 63 is a vehicle on which the in-vehicle device 11 corresponding to the authentication code stored in the storage unit 65 of the portable device 63 is mounted.

(2-1) Processing by the portable device 63 A processing procedure of signal transmission processing executed by the CPU 67 of the portable device 63 will be described based on a flowchart shown in FIG.

First, in S61 of this process, it is determined whether or not an input operation to the designated vehicle operation button has been accepted. If there is no input operation (S61: NO), S61 is executed again. That is, it waits until there is an input operation on the designated vehicle operation button. If there is an input operation (S61: YES), the process proceeds to S62.

In subsequent S62, it is determined whether or not history information is stored in the storage unit 65. If history information is not stored (S62: NO), this process ends. On the other hand, if the history information is stored (S62: YES), the process proceeds to S63.

In subsequent S63, referring to the history information, the last operated vehicle 3 is determined as the transmission vehicle. That is, the in-vehicle device 11 mounted on the transmission vehicle is determined as the in-vehicle device 11 to which the portable device 63 should transmit a signal.

In subsequent S64, the authentication code and the control command corresponding to the in-vehicle device 11 of the transmission vehicle determined in S63 are transmitted to the in-vehicle device 11. The control command is a command for causing the vehicle-mounted device 11 to lock or unlock the door, and the content of the command is determined by which of the designated vehicle lock button 69a and the designated vehicle unlock button 69b is input. The CPU 67 that performs the process of S65 and the transmission unit 33 that transmits a signal are examples of the signal transmission unit in the present disclosure. After S65, this process is terminated.

(2-2) Processing by the in-vehicle device 11 The processing executed by the in-vehicle device 11 is the same as the processing shown in FIG.

(3) Effect The vehicle control system 61 configured as described above performs the operation using the portable device 63 at the end of the plurality of vehicles 3 when the user performs an input operation on the designated vehicle operation button. Further, door lock or unlock can be executed on the vehicle 3, which improves user convenience.

In the present embodiment, the configuration in which the last operated vehicle 3 is determined as the operation target vehicle 3 is exemplified, but the operation target vehicle 3 may be determined under other conditions based on the control history. For example, with reference to the operation content operated with the portable device 63, the configuration may be such that the vehicle 3 that has performed a predetermined operation last is determined as the vehicle 3 to be operated.

[Example 4]
(1) Overall Configuration Since the vehicle control system 81 of the fourth embodiment is partially different from the vehicle control system 41 of the second embodiment, the differences will be mainly described and vehicle control will be described. A description of the same points as in the system 41 will be omitted.

The vehicle control system 81 of the present embodiment includes a plurality of in-vehicle devices 83 and portable devices 85 as shown in FIG. In the vehicle control system 81, when the user performs a predetermined input operation on the portable device 85, the door 3 of the operation target vehicle 3 is locked or unlocked. At this time, not only can the signal be directly transmitted from the portable device 85 to the vehicle-mounted device 83 mounted on the operation target vehicle, but the signal can be transmitted via one or more other vehicle-mounted devices. .

The in-vehicle device 83 includes a bidirectional communication device 47 similar to the in-vehicle device 43 of the second embodiment. The CPU 87 a included in the verification ECU 87 governs the function of the in-vehicle device 83.

The portable device 85 stores, in the storage unit 89, the authentication code information of each of the plurality of in-vehicle devices 83 mounted on the plurality of vehicles 3. The storage unit 89 is an example of an authentication code storage unit in the present disclosure. The CPU 91 controls the function of the portable device 85.

The portable device 85 includes a lock button 93a, an unlock button 93b, and a changeover switch 93c for switching the operation target vehicle 3 as the operation button group 93. The lock button 93a and the unlock button 93b are examples of the input unit in the present disclosure, and the changeover switch 93c is an example of the in-vehicle device selection unit in the present disclosure.

(2) Remote keyless entry control in the vehicle control system 81 When the operation button group 93 of the portable device 85 is operated by the user, the vehicle control system 81 uses the changeover switch 93c from among the vehicles 3 registered in the portable device 85. Lock or unlock control of the door of the vehicle 3 set as the operation target vehicle is executed. In other words, the vehicle 3 registered in the portable device 85 is a vehicle on which the in-vehicle device 83 corresponding to a plurality of authentication codes stored in the storage unit 89 of the portable device 85 is mounted.

(2-1) Processing by Portable Device 85 A processing procedure of signal transmission processing executed by the CPU 91 of the portable device 85 will be described based on the flowchart shown in FIG.

First, in S81 of this process, it is determined whether or not an input operation to either the lock button 93a or the unlock button 93b of the operation button group 93 is accepted. If there is no input operation (S81: NO), S81 is executed again. That is, it waits until there is an input operation on the lock button 93a or the unlock button 93b.

If there is an input operation (S81: YES), the process proceeds to S82. Note that the in-vehicle device 83 mounted on the operation target vehicle set by the change-over switch 93c is the in-vehicle device 83 that should perform door locking or unlocking.

In subsequent S82, a transmission vehicle to which a signal is to be transmitted is determined. In this process, since signals are transmitted to the plurality of vehicles 3 in S82 to S84, the transmission vehicle here is not necessarily the same as the operation target vehicle.

In S82, one of the plurality of authentication codes stored in the storage unit 89 is selected. A flag capable of determining whether or not the authentication code has been selected can be attached to the authentication code. In S82, any one of the authentication codes without the selected flag is selected. A selected flag is attached to the selected authentication code.

In the next S83, all authentication codes and control commands held by the portable device 85 are transmitted to the in-vehicle device 83. In the present embodiment, the in-vehicle device 83 that receives these signals transmitted from the portable device 85 is referred to as a first in-vehicle device 83 for convenience.

All the above-mentioned authentication codes are a plurality of authentication codes stored in the storage unit 89. Among these, the authentication code selected in S82 (hereinafter referred to as authentication code A) is transmitted as a signal for collating with the authentication code of the first in-vehicle device 83. Also, authentication code data, which is data indicating all authentication code information, is transmitted together with the authentication code A. In the authentication code data, information of two or more authentication codes is shown.

Further, the above-described control command is a command for causing the vehicle-mounted device 83 mounted on the operation target vehicle to perform door locking or unlocking. The CPU 91 that performs the process of S83 and the transmission unit 33 that transmits a signal are examples of the signal transmission unit in the present disclosure.

In the next S84, it is determined whether there is registered vehicle information other than the transmitted vehicle. Here, it is checked whether or not there is an authentication code without a selected flag. If there is an authentication code without a selected flag, it is determined that there is registered vehicle information other than the transmitted vehicle (that is, there is an untransmitted vehicle) (S84: YES), and the process returns to S82. On the other hand, if there is no registered vehicle information other than the transmitted vehicle (S84: NO), it is determined that there is no untransmitted vehicle, and this process is terminated.

(2-2) Processing by the in-vehicle device 83 (2-2-1) Hopping communication processing The processing procedure of the hopping communication processing executed by the CPU 87a of the in-vehicle device 83 will be described based on the flowchart shown in FIG.

This process is a process executed by the vehicle-mounted device 83 mounted on the vehicle 3 other than the operation target vehicle. The signal transmitted by the portable device 85 in S83 of FIG. 13 or the other vehicle-mounted device 83 is described later. The trigger is triggered by the reception of the signal transmitted in S95.

In S91 of this process, it is determined whether or not the in-vehicle device 83 has received the signal. Here, the same signal is a signal serving as a trigger for starting the above-described processing, and is a signal transmitted based on a series of input operations to the operation button group 93 of the portable device 85 by the user. That is, when the user performs an input operation again, even if the content of the operation itself is the same, it is not treated as the same signal. If the same signal has been received (S91: YES), this process ends. On the other hand, if the same signal has not been received (S91: NO), the process proceeds to S92.

In the next S92, the authentication code A included in the transmission signal transmitted from the portable device 85 in S83 of FIG. 13 and the authentication included in the transmission signal transmitted from the other in-vehicle device 83 that executes S95 of this process. It is determined whether or not the authentication is OK by comparing one of the codes B with the authentication code assigned to the in-vehicle device 83. The authentication code A and the authentication code B are basically the same type of signal except that the signal source is different.

If the authentication is not OK (S92: NO), that is, if the authentication codes do not match, this process is terminated. Note that the matching of the authentication codes is not limited to a case where both authentication codes completely match, and includes, for example, a case where both authentication codes satisfy a pre-registered correspondence.

On the other hand, if the authentication is OK (S92: YES), that is, if the authentication codes match, the process proceeds to S93.

In the next S93, it is determined whether there is registered vehicle information other than the own vehicle and the receiving vehicle. The receiving vehicle referred to here is a vehicle 3 equipped with the in-vehicle device 83 that transmits a signal serving as a trigger for this processing to the in-vehicle device 83. That is, in S93, it is determined whether or not an authentication code other than the in-vehicle device 83 mounted on the host vehicle and the receiving vehicle is indicated in the authentication code data transmitted in S83.

If there is no registered vehicle information other than the own vehicle and the receiving vehicle (S93: NO), this process is terminated. On the other hand, if there is registered vehicle information other than the own vehicle and the receiving vehicle (S93: YES), the process proceeds to S94.

The subsequent S94 to S96 are repeatedly executed according to the number of registered vehicle information other than the above-described own vehicle and receiving vehicle.

In S94, a transmission vehicle to which a signal is to be transmitted is determined. Here, from among the authentication codes indicated in the authentication code data transmitted in S83, the authentication code of the in-vehicle device 83 of the own vehicle, the authentication code of the in-vehicle device 83 of the receiving vehicle, and already selected in S94 Any one authentication code excluding the authentication code is selected.

The method for selecting the authentication code in S94 is not particularly limited. The in-vehicle device 83 to which the selected authentication code is assigned is referred to as a second in-vehicle device 83 for convenience.

In subsequent S95, the received authentication code excluding the own vehicle and the receiving vehicle and the control command are transmitted to the second vehicle-mounted device 83. Here, the received authentication code excluding the own vehicle and the receiving vehicle corresponds to the in-vehicle device 83 excluding the in-vehicle device 83 mounted on the own vehicle and the receiving vehicle in the authentication code data transmitted in S83. It is an authentication code.

Of the authentication codes transmitted to the second vehicle-mounted device 83, the authentication code selected in S94 (hereinafter referred to as the authentication code B) is a signal for collating with the authentication code of the second vehicle-mounted device 83. As sent. In addition, other authentication codes excluding the authentication code of the in-vehicle device 83 of the own vehicle and the receiving vehicle are transmitted as authentication code data.

The control command transmitted to the second vehicle-mounted device 83 is a command for controlling the door lock described above. In addition, CPU87a which performs the process of S95 is an example of the 1st vehicle equipment control part and the 2nd vehicle equipment control part which perform the 2nd process in this indication.

In subsequent S96, it is determined whether there is registered vehicle information other than the transmitted vehicle. Here, in the authentication code data transmitted in S83, the authentication code of the in-vehicle device 83 of the own vehicle, the authentication code of the in-vehicle device 83 of the receiving vehicle, and the in-vehicle that has already been selected in S94 and transmitted a signal in S95. It is determined whether an authentication code other than the authentication code of the machine 83 is indicated. If there is such an authentication code, it is determined that there is registered vehicle information other than the transmitted vehicle (that is, there is an untransmitted vehicle) (S96: YES), and the process returns to S94. On the other hand, if the above authentication code is not present (S96: NO), it is determined that there is no untransmitted vehicle, and this process is terminated.

(2-2-2) Door Lock Processing The door lock processing procedure executed by the CPU 87a of the in-vehicle device 83 will be described based on the flowchart shown in FIG. This process is a process executed by the operation target vehicle, and is triggered by the signal transmitted by the portable device 85 in S83 of FIG. 13 or the signal transmitted by the other vehicle-mounted device 83 in S95 of FIG. .

First, in S101 of this process, either the authentication code A transmitted from the portable device 85 in S83 of FIG. 13 or the authentication code B transmitted from the in-vehicle device 83 in S95 of FIG. It is determined whether or not the authentication is OK by checking with the assigned authentication code. If the authentication is not OK (S101: NO), that is, if the authentication codes do not match, this process ends.

On the other hand, if the authentication is OK (S101: YES), that is, if the authentication codes match, the door is locked or unlocked according to the control command included in the transmission signal (S102). After this S102, this process ends. In addition, CPU87a which performs this door lock process is an example of the 1st vehicle equipment control part and 2nd vehicle equipment control part which perform the 1st process in this indication.

(3) Effect The vehicle control system 81 configured as described above not only directly transmits a signal from the portable device 85 to the operation target vehicle set by the user using the changeover switch 93c among the plurality of vehicles 3. A signal is also transmitted to the vehicle-mounted device 83 mounted on the vehicle 3 other than the operation target vehicle, and the vehicle-mounted device 83 further transmits a signal to another vehicle-mounted device 83.

Therefore, even if the operation target vehicle does not exist in the vicinity of the user, a signal can be transmitted from the portable device 85 to the in-vehicle device 83 of the operation target vehicle via the network constructed by the plurality of vehicles 3. Thereby, a door lock or unlocking can be performed with respect to the vehicle 3 which exists in the position which has a distance from the portable device 85, and a user's convenience improves.

In the present embodiment, the configuration in which the operation target vehicle is determined by the user operating the changeover switch 93c is illustrated, but the operation target vehicle may be determined based on an operation other than the input operation to the changeover switch 93c. . For example, as described in the third embodiment, it can be considered that the operation target vehicle is determined based on the user operation history.

Further, in the present embodiment, a configuration in which transmission processing is performed from the portable device 85 and the first vehicle-mounted device 83 to the vehicle-mounted devices 83 mounted on all the vehicles 3 capable of transmitting signals, respectively. However, the configuration may be such that transmission processing is performed only for some of the vehicle-mounted devices 83.
