Thus, the parking position can be notified to an external person, and the vehicle forwarding request or vehicle lending can be performed. According to the specific feature of this invention, parking position information is transmitted with a keyless entry code by the transmission part. This makes it possible to notify the person who can enter the vehicle of the parking position. The parking position information in the above is a code for specifying a parking facility, for example. Further, in the environment where the parking position information is transmitted from the parking facility, if the input unit receives the parking position information and receives the parking position information, the parking position information can be automatically obtained. In addition, when the parking position information includes, for example, information for identifying the parking position in the parking facility transmitted from the parking facility, the vehicle actually exists not only in the parking lot but also in a large parking lot. It is possible to specify up to the position to be performed. The parking position information may be GPS information indicating the parking position of the vehicle. According to another aspect of the present invention, a receiving unit that receives parking position information of a vehicle transmitted from an external transmission device, a parking position information holding unit that holds parking position information received by the receiving unit, and the holding A communication device having a display unit that displays parking position information held by the unit is provided. This configuration is on the receiving side of the parking position, and in this way, by receiving information on the parking position, it arrives parked at a place where it does not know, responds to the vehicle's forwarding request, or lends the vehicle You can receive. Further, if a keyless entry code is received at the same time as described above, the vehicle can be reached and driven.

According to another feature of the present invention, an input unit for inputting the forwarding destination information of the vehicle, a forwarding destination information holding unit for holding the inputted forwarding destination information, and the forwarding destination information held by the holding unit are externally transmitted. There is provided a communication device including a transmission unit that transmits to a reception device. Thereby, it is possible to notify the external person of the information on the forwarding destination of the vehicle and make a request for forwarding the vehicle. In addition, if it is configured to simultaneously transmit information on the parking position of the vehicle and the keyless entry code together with the forwarding destination as a specific configuration, for example, when the driver is in a drunk state, the driver will forward the vehicle from the parking lot, You can also pick up and send it to your home. According to another feature of the present invention, a receiving unit that receives forwarding destination information of a vehicle transmitted from an external transmission device, a forwarding destination information holding unit that holds the received forwarding destination information, and a forwarding destination information holding unit There is provided a communication device having a display unit for displaying forwarding destination information to be held.

A communication device having a display unit for displaying position information is provided. Thus, for example, when searching for a vehicle parked in a large parking lot, by receiving a processing system provided locally in the parking lot, the parking position information that can be used locally only in the parking lot is held. Even in such a case, the parking position of the vehicle in the parking lot can be specified. This is useful not only when searching for a vehicle in a parking lot when accepting a surrogate operation or lending a vehicle, but also when forgetting the position of a vehicle parked by itself.

  FIG. 1 is a block diagram showing a first example of a keyless entry system according to an embodiment of the present invention. The first embodiment constitutes a system including a plurality of mobile phones, and FIG. 1 shows a first mobile phone 1 and a second mobile phone 2. In FIG. 1, the internal configuration of the second mobile phone 2 is illustrated in a simplified manner, but the content is basically the same as that of the first mobile phone 1. In FIG. 1, only two mobile phones are shown for simplicity, but a third and more unspecified number of mobile phones having the same configuration may be included. The keyless entry system according to the embodiment of the present invention further includes a vehicle 3 and a parking lot 4.

The first mobile phone 1 has a first mobile control unit 6 composed of a computer that controls the entire mobile phone, and controls the first telephone function unit 10 and the like according to the operation of the telephone operation unit 8. The function of the first portable control unit 6 is executed by software stored in the storage unit 12. The storage unit 12 also temporarily stores various data necessary for controlling the entire first mobile phone 1. The first portable control unit 6 further controls the display unit 14 to perform GUI display in cooperation with the operation of the telephone operation unit 8 and display the control result.

The GPS unit 16 obtains information on the latitude, longitude, and altitude, which are absolute position information of the first mobile phone 1, from the satellite or the nearest broadcasting station based on the GPS system and sends the information to the first mobile control unit 6. This absolute position information is displayed on the display unit 14 together with the map under the control of the first portable control unit 6 and provided as navigation information.

The first mobile phone 1 can perform wireless communication via a telephone line including a normal call by the first telephone function unit 10 and the first telephone communication unit 18. The first mobile phone 1 is further provided with a first mobile short-range communication unit 20 using a wireless LAN or the like, and wireless communication with other mobile phones or the like existing in the short-range communication range is possible. Yes. The first portable short-range communication unit 20 is based on a standard that is not problematic in terms of laws and regulations, and has a limited communication area but does not incur charges like a telephone line.

The first portable short-range communication unit 20 transmits the absolute position information acquired by the GPS unit 16 to the GPS unit of the other device in addition to the communication of the entry code described later, and the other device is the GPS unit. The acquired absolute position information can be received. As a result, not only the own position but also the positions of other devices can be displayed on the same map on the display unit 14, and the relative relationship between them can be confirmed on the map. Details thereof are described in Japanese Patent Application No. 2007-28393 by the same applicant. As will be described later, according to this function, for example, the relationship between the current position of the vehicle 3 stopped in the vast parking lot 4 and the first mobile phone 1 can be known, and it is easy to reach the vehicle 3. . The first mobile phone 1 also has a camera unit 22 and can store the captured image in the storage unit 12 and can transmit the image to another mobile phone by the first telephone communication unit 18. Can do.

The first mobile phone 1 is powered by a rechargeable main power supply 24, and the storage unit 12 is further backed up by an auxiliary power supply 26 made of a lithium battery or the like. This prevents volatilization of information stored in the storage unit 12 when the main power supply 24 is discharged or replaced. The first mobile phone 1 further includes a keyless entry communication unit 28 and a keyless entry code storage unit 30 that cooperates therewith. These are supplied with power from the auxiliary power source 26 and basically function regardless of the state of charge of the main power source 24 and its on / off state. Since the power consumption of the keyless entry communication unit 28 is weaker than that of the first short-range communication unit 20, the auxiliary power supply 26 of the storage unit 12 is shared in this way.

Because of this function, the first mobile control unit 6 is in a state where it is determined that charging of the main power supply 24 is insufficient for normal mobile phone functions even when the main power supply 24 is turned off. However, it is activated in the low-speed power saving mode so as to perform the minimum function for detecting the entry operation in the vehicle 3 received by the operation of the telephone operation unit 8 for the keyless entry operation or the keyless entry communication unit 28. ing. The keyless entry code storage unit 30 is also connected to the first portable control unit 6, and the locking and unlocking of the vehicle 3 based on the entry code stored in the keyless entry code storage unit 30 is performed by the keyless entry communication unit. This is possible not only by 28 but also by the first portable short-range communication unit 20. However, as will be described later, basically, the keyless entry communication unit 28 locks and unlocks the vehicle 3.

In the first embodiment of FIG. 1, the keyless entry communication unit 28 is controlled by the first portable control unit 6 as described above. However, as a modified embodiment, the keyless entry communication unit is completely configured. A configuration independent of the first portable control unit 6 is also possible. In this case, it is necessary to provide a dedicated operation unit for detecting a keyless entry operation. Note that a part of the operation keys of the telephone operation unit 8 may also be used as such a keyless entry operation unit, and the keyless entry communication unit 28 may directly detect the operation of this operation key.

The second mobile phone 2 has the same configuration as the first mobile phone 1 as already described, and the description thereof is omitted unless necessary to avoid duplication. As already described, in FIG. 1, the configuration of the second mobile phone 2 is omitted except for the second mobile control unit 32, the second telephone communication unit 34, and the second mobile short-range communication unit 36. ing. Further, in FIG. 1, the first mobile phone 1 and the second mobile phone 2 are illustrated as performing direct communication, but as is well known, the mobile phone is based on infrastructure communication of a communication line. The first telephone communication unit 18 and the second telephone communication unit 34 communicate with each other via a base station. On the other hand, in FIG. 1, the first mobile phone 1 and the second mobile phone 2 can perform direct ad hoc communication by the first mobile short-range communication unit 20 and the second mobile short-range communication unit 36.

The vehicle 3 includes a vehicle control unit 38 including a computer that controls the entire vehicle, and controls the vehicle function unit 42 and the like according to the operation of the vehicle operation unit 40. The function of the vehicle control unit 38 is executed by software stored in the storage unit 44. The storage unit 44 also temporarily stores various data necessary for controlling the vehicle 3.

The GPS unit 46 is the same as the GPS unit 16 in the first mobile phone 1, and based on the GPS system, information on latitude, longitude, and altitude, which is absolute position information of the vehicle 3, from a satellite or the nearest broadcasting station. Obtained and sent to the vehicle control unit 38. This absolute position information is displayed on a car navigation screen (not shown) together with a map under the control of the vehicle control unit 38. The vehicle 3 is also provided with a vehicle short-range communication unit 48 using a wireless LAN or the like, and wireless communication with the first portable short-range communication unit 20 or the like existing in the short-range communication range is possible. Of course, the vehicle short-range communication unit 48 is based on the same standard as the first portable short-range communication unit 20 and has a limited communication area, but does not incur charges like a telephone line.

The vehicle 3 further has a keyless entry communication unit 50, and communicates an entry code with the keyless entry communication unit 28 of the first mobile phone 1. Then, the entry code transmitted from the keyless entry code storage unit 30 through the keyless entry communication unit 28 is received by the keyless entry communication unit 50, and when it is authenticated by the keyless entry code management unit 52, the result is obtained. Is notified to the vehicle control unit 38. As a result, the vehicle control unit 38 instructs the door lock unit 54 to lock and unlock. Furthermore, even when the holder of the first mobile phone 1 performs an engine start operation with the vehicle operation unit 40, the engine lock is released by communication between the keyless entry communication units, and the engine can be started. That is, in this case, since the holder of the first mobile phone 1 is in the driver's seat of the vehicle 3, communication between the keyless entry communication unit 28 and the keyless entry communication unit 50 is possible. Then, communication between the two is performed according to the engine start operation, and when the keyless entry code management unit 52 authenticates that the entry code in the keyless entry code storage unit 30 is correct, the result is the vehicle control unit. 38 is notified. In response to this, the vehicle control unit 38 releases the lock of the engine lock unit 56 and enables the engine to start.

As described above, the entry code in the keyless entry code storage unit 30 of the first mobile phone 1 is transmitted from the first mobile short-range communication unit 20 to the vehicle short-range communication of the vehicle 3 via the first mobile control unit 6. Can be transmitted to the unit 48. This is effective when the auxiliary power supply 26 is exhausted. In this case, the vehicle control unit 38 sends the entry code received by the vehicle short-range communication unit 48 to the keyless entry code management unit 52, and authenticates whether this is correct. Based on the result, the vehicle control unit 38 instructs the door lock unit 54 to lock and unlock. In the above case, even when the engine start operation is performed, the entry code in the keyless entry code storage unit 30 is transmitted from the first portable short-range communication unit 20 to the vehicle short-range communication unit of the vehicle 3 via the first portable control unit 6. 48. When the keyless entry code management unit 52 authenticates that the entry code is correct, the vehicle control unit 38 is notified of the result. In response to this, the vehicle control unit 38 releases the lock of the engine lock unit 56 and enables the engine to start.

The above is a case where the owner of the first mobile phone 1 is also the owner of the vehicle 3. Next, the owner of the second mobile phone 2 owns the vehicle 3 and the first mobile phone The case where the telephone 1 is the property of the driving agent will be described. As already described, although not shown in FIG. 1, the second mobile phone 2 is the same as the first mobile phone 1, and includes a keyless entry code storage unit, a keyless entry communication unit, and the like. It has all configurations. The situation as described above occurs, for example, when the owner of the vehicle 3 is in a drinking state and requests a driving agent to forward the vehicle 3 and perform a driving operation to the home. At this time, the owner of the second mobile phone 2 who is the owner of the vehicle 3 passes the temporary entry code of the vehicle 3 from the second telephone communication unit 34 to the first telephone communication unit 18 of the driving agent through the telephone line. Send. As a result, the temporary entry code received is stored in the keyless entry code storage unit 30 of the first mobile phone. Hereinafter, the door lock unlocking of the vehicle 3 by the first mobile phone 1 and the first mobile phone 1 are performed in the same manner as described above. Engine lock can be released. Therefore, the driving agent can forward the vehicle 3 to a banquet hall where the vehicle owner is located, and can pick up the vehicle owner and drive the vehicle 3 to his home. The temporary entry code is limited to the requested proxy operation and is invalid after that. Details of the temporary entry code transmission and the like will be described later.

The parking lot 4 has a parking lot control unit 58 formed of a computer that controls the entire parking lot, and executes control by software stored in the storage unit 60. The storage unit 60 also temporarily stores various data necessary for controlling the parking lot 4. The parking lot 4 further includes a parking lot first short-range communication unit 62 and a parking lot second short-range communication unit 64 which are installed at different places in the parking lot. In addition, in the parking lot 4, in order to ensure the communication area in a parking lot, the 3rd and more short distance communication part is provided as needed. In FIG. 1, two short-range communication units are illustrated for simplicity.

The plurality of short-range communication units in these parking lots share and secure the communication area, and the first portable short-range communication unit 20 detects the short-range communication unit with which the first portable short-range communication unit 20 can communicate. The parking lot control unit 58 determines where the telephone 1 is in the parking lot 4. Furthermore, when the first portable short-range communication unit 62 and the second portable short-range communication unit 64 simultaneously receive the radio waves of the first portable short-range communication unit, for example, the parking lot control unit 58 is based on the triangle point communication. The position of the mobile phone can be determined more accurately. This makes it possible to detect the position of the first mobile phone 1 even if the first mobile phone 1 is outside the satellite radio wave area such as the parking lot 4 and the GPS 16 does not function. Note that the position of the first mobile phone 1 determined by the parking lot control unit 58 is transmitted from the nearest parking lot short-range communication unit to the first portable short-range communication unit 20. Similarly, for the parking position of the vehicle 3, when the GPS unit 46 of the vehicle 3 does not function, the parking lot control unit detects the communication between the vehicle short-range communication unit 48 and the second near-field communication unit 64. And transmitted to the first portable short-range communication unit 20.

As described above, the first mobile phone 1 knows its own position by its own GPS unit 16, and the position information of the vehicle 3 detected by the GPS unit 46 of the vehicle 3 is transmitted by the first mobile short-range communication unit 20. Therefore, even if the substitute driver does not know the position of the vehicle 3, the vehicle 3 can be reached by displaying the positional relationship between the two on the display unit 14. Furthermore, even when the GPS unit does not function, the first portable short-range communication unit 20 can receive information on its own position and the position of the vehicle 3 from the parking lot control unit 58, so that the positional relationship between the two is similarly displayed. It is displayed on the part 14 and can reach the vehicle 3 easily. The position information of the vehicle 3 is transmitted as long as the first portable short-range communication is performed unless the keyless entry code storage unit of the first mobile phone stores its own entry code or the temporary entry code received from the owner of the vehicle. Cannot be received by unit 20. Therefore, the position of the vehicle 3 is not transmitted to an unnecessary third party.

FIG. 2 is a basic flowchart of the function of the first portable control unit 6 in the first embodiment of FIG. 1, in which the main power supply 24 is attached to the first mobile phone 1, charging starts to the main power supply 24, or auxiliary The operation starts when the power supply 26 is attached. When the flow starts, it is first checked in step S2 whether the auxiliary power supply 26 is OK. The level at which it is determined that “auxiliary power is not OK” is a limit that the backup of the storage unit 12 and the keyless entry code storage unit cannot be guaranteed if the auxiliary power source 26 is consumed and power is supplied to the keyless entry communication unit. Set to the previous level. In other words, as long as power is not supplied to the keyless entry communication unit, even at this level, the backup itself is at a level that is possible for the time being. If the auxiliary power supply is not OK in step S2, the process proceeds to step S4 to check whether the main power supply 24 is charged. The level that should be judged that “the main power supply is not charged” is the minimum operation of the first mobile control unit itself, but the mobile phone function is forcibly stopped because of insufficient charge for normal mobile phone operation It is a level that should be made. If charging of the main power source is OK in step S4, the process proceeds to step S6, and a warning display for prompting replacement of the auxiliary power source 26 is performed. Then, the process proceeds to step S8 while continuing this display.

In step S8, in order to prevent further consumption of the auxiliary power supply 26, the function of the keyless entry communication unit 28 is stopped proactively to disable communication. Corresponding to this, keyless entry communication by the first portable short-range communication unit 20 is enabled in step S10. The keyless entry communication by the first portable short-range communication unit 20 is not normally performed, but this is performed only when the process proceeds from step S2 to step S8 as described above. This is because the first portable short-range communication unit 20 is powered by the main power supply 24. The main power supply 24 needs to be charged frequently to supply power to the normal mobile phone function. If the main power supply 24 is neglected, the entire mobile phone 1 will not function. Does not work. Therefore, if the first portable short-range communication unit 20 is regularly used for the keyless entry function, the operation of the vehicle 3 including the keyless entry becomes impossible due to the battery running out of the cellular phone 1 which may occur frequently. This is inconvenient and in some cases dangerous. Therefore, normally, the keyless entry is performed by the keyless entry communication unit 28 that is powered by the auxiliary power supply 26 and functions regardless of the charging state of the main power supply 24 and on / off thereof, and the keyless entry code storage unit 30 that cooperates with the keyless entry communication unit 28. Do. However, since the auxiliary power supply 26 may be consumed due to long-term use, a flow from step S2 to step S10 is prepared as an emergency means at that time. This is based on the premise that when the auxiliary power supply 26 is consumed, the main power supply 24 is unlikely to be under charged.

When the keyless entry communication by the first portable short-range communication unit 20 is enabled in step S10, the process proceeds to step S12, and the keyless entry interrupt as the first portable control unit 6 is enabled. This interruption is applied when a keyless entry operation is performed by the telephone operation unit 8. In addition, the vehicle control unit 38 detects that an unlock button outside the vehicle, which is a part of the vehicle operation unit 40 of the vehicle 3, is operated, and the vehicle short-range communication unit 48 changes the first portable short-range communication unit 20. This interrupt is also applied when this is notified. Step S12 enables these interruptions, but normally, interruption to the first portable control unit 6 based on these operations is prohibited, and the keyless entry function based on these operations is keyless. It is executed by the entry communication unit 28.

Next, in step S14, the mobile phone function is initialized, and the flow ends. When it is determined in step S2 that the auxiliary power supply 26 is OK, the first mobile phone control unit 6 does not need to respond to the keyless entry operation, so the process proceeds to step S16 and the normal operation by the keyless entry communication unit 28 is performed. The keyless entry state is confirmed and the process proceeds to step S14. In step S16, the keyless entry communication unit 28 functions normally every time there is an opportunity such as the attachment of the main power supply 24 to the first mobile phone 1, the start of charging of the main power supply 24, or the attachment of the auxiliary power supply 26. This is provided to check whether or not to perform the keyless entry interrupt to the first portable control unit when it is possible.

If the main power supply 24 is not OK in step S4, the process proceeds to step S18 to check whether charging is in progress. Since the mobile phone 1 is capable of functioning during charging, the process proceeds to step S6, and the operations in step S6 and subsequent steps are performed by the power supplied from the charger. Such an operation is possible, for example, when the mobile phone 1 is charged in the vehicle. On the other hand, if it is not charging in step S18, the function of the mobile phone 1 is impossible, and the flow is immediately terminated. For example, in this case, the main power supply 24 is not charged when the worn auxiliary power supply 26 is erroneously attached, or the uncharged main power supply 24 is attached when the auxiliary power supply 26 is consumed. It corresponds to. Naturally, if no power is supplied to the first portable control unit 6, the flow of FIG. 2 itself does not start.

FIG. 3 is a flowchart showing functions when a keyless entry operation is performed in the first portable control unit 6 of the first embodiment of FIG. In the flow, the vehicle control unit 38 detects that a keyless entry operation is performed by the telephone operation unit 8 or that a lock release button outside the vehicle which is a part of the vehicle operation unit 40 of the vehicle 3 is operated. When this is notified from the keyless entry communication unit 50 of the vehicle 3 to the keyless entry communication unit 28 of the first mobile phone 1, or an unlock button outside the vehicle that is part of the vehicle operation unit 40 of the vehicle 3 is operated. The vehicle control unit 38 detects that this has been done, and the vehicle short-distance communication unit 48 is notified of this by the first portable short-distance communication unit 20. Even when the engine starting operation by the vehicle operation unit 40 is detected by the vehicle control unit 38, the flow of FIG. 3 starts in the same manner as the operation detection of the unlock button.

When the flow starts, it is checked in step S22 whether the auxiliary power source 26 is OK. If not OK, the process proceeds to step S24 to check whether the main power supply 24 is charged. If charging of the main power source is OK in step S24, the process proceeds to step S26, and a warning display for prompting replacement of the auxiliary power source 26 is performed. Then, the process proceeds to step S28 while continuing this display. In step S28, the function of the keyless entry communication unit 28 is stopped, communication is disabled, and the process proceeds to step S30. In step S30, if the main power supply 24 is not on, it is turned on in step S32 and the process proceeds to step S32. This is because if the main power supply 24 is turned off, the first portable short-range communication unit 20 is not energized and keyless entry cannot be performed. On the other hand, if the main power supply is already on in step S30, the process directly proceeds to step S34.

In step S34, keyless entry such as locking / unlocking of the door lock unit 54 and release of the engine lock is executed based on communication by the first portable short-range communication unit 20. Next, in step S36, it is checked whether or not there is a history in which the main power supply is automatically turned on in step S32. If there is a history, the process proceeds to step S38, where the main power supply is automatically turned off and the flow ends. This is to restore the main power supply of the mobile phone that is automatically turned on for execution of keyless entry. On the other hand, if there is no history of main power supply automatic ON in step S36, it means that the main power supply of the mobile phone was originally turned on before the detection of the keyless entry operation. .

When it is determined in step S22 that the auxiliary power supply 26 is OK, the first mobile phone control unit 6 does not need to respond to the keyless entry operation, so the process proceeds to step S40, and the normal operation by the keyless entry communication unit 28 is performed. Confirm the keyless entry status and end the flow. This step S40 checks whether or not the keyless entry communication unit 28 functions normally every time there is an opportunity for a keyless entry operation, and enables a keyless entry interrupt to the first portable control unit. It is provided to make this impossible in some cases. If the main power supply is not charged in step S24, neither the auxiliary power supply nor the main power supply can execute the keyless entry, and the flow is immediately terminated.

FIG. 4 is a flowchart showing functions of the first mobile control unit 6 when the main power supply of the mobile phone is turned on in the first embodiment of FIG. When the flow starts, it is checked in step S52 whether or not charging of the main power source is OK. If the charging is OK, the process proceeds to step S54 to check whether the auxiliary power supply 26 is OK. If the auxiliary power supply is not OK, the process proceeds to step S56, and a warning display for urging replacement of the auxiliary power supply 26 is performed. Then, the process proceeds to step S58 while continuing this display.

In step S58, in order to prevent further consumption of the auxiliary power supply 26, the function of the keyless entry communication unit 28 is stopped proactively to disable communication. Correspondingly, keyless entry communication by the first portable short-range communication unit 20 is enabled in step S60, and the process proceeds to normal cellular phone function processing in step S62. When the normal telephone function process is stopped, the flow is terminated. When it is determined in step S54 that the auxiliary power supply 26 is OK, the first mobile phone control unit 6 does not need to respond to the keyless entry operation, and the process directly proceeds to step S62. If it is not detected in step S52 that the main power supply is charged, the flow is immediately terminated. As described above, by checking whether or not the auxiliary power source is OK every time the main power source of the mobile phone is turned on, a situation in which keyless entry by the auxiliary power source cannot be performed is detected. If the auxiliary power supply is not OK, the keyless entry function is automatically switched from the keyless entry communication unit to the short-range communication unit, and the auxiliary power supply is further consumed, making it impossible to back up the storage unit 12. To prevent.

FIG. 5 is a flowchart showing the function of the first portable control unit 6 when a telephone call operation to a previously registered substitute driver is performed by the telephone operation unit 8 in the first embodiment of FIG. It is. When the flow starts, a call is made to the telephone number of the substitute driver registered in step S72, and it is checked whether or not the line is connected in step S74. When the connection is confirmed, the process proceeds to step S76, and it is checked whether or not an operation for transmitting the entry code is performed by the telephone operation unit 8. If it is confirmed that this operation has been performed, the process proceeds to step S78, a signal requesting authentication is superimposed on the voice signal of the telephone, and the process proceeds to step S80. In step S80, it is checked whether or not a predetermined time has passed after the transmission of the authentication request signal. If not, the process proceeds to step S82, and an authentication signal that is superposed on the audio signal according to the request has been extracted. Check it out.

When the authentication reply signal is extracted from the voice signal in step S82, the process proceeds to step S84, where it is checked against the reference data, and it is checked whether the authentication result is OK. If the authentication result is OK, the process proceeds to step S86. On the other hand, if an authentication reply signal is not extracted in step S82, or if authentication is not OK in step S84, the process returns to step S80, and thereafter, steps S80 to S84 are repeated until a predetermined time elapses, and authentication is OK. Wait for. When the authentication is successful, in step S86, the temporary entry code is read from the keyless entry code storage unit 30, and in step S88, this is superimposed on the audio signal and transmitted to the substitute driver's phone. In step S90, it is checked whether or not a predetermined time has elapsed after transmission. If not, whether or not a confirmation signal indicating that the temporary entry code has been received can be extracted from the voice signal from the substitute driver's telephone in step S92. To check. If this extraction is possible, the process proceeds to step S94. If extraction is not possible, the process returns to step S88, and the temporary entry code is transmitted again. Thereafter, steps S88 to S92 are repeated until a predetermined time elapses, and extraction of a reception confirmation signal is awaited.

When the reception confirmation signal is extracted in step S92, the temporary entry code is surely transmitted to the substitute driver. Therefore, the process proceeds to step S94, and it is checked whether the line disconnection operation has been performed. If the line is disconnected, the process proceeds to step S96. On the other hand, if a line disconnection operation is not detected in step S94, the process returns to step S76, and thereafter steps S76 to S94 are repeated. When a predetermined time has elapsed in step S80 or step S90, the process proceeds to step S94, where it is checked whether an operation for disconnecting the line and ending the flow has been performed. If the line disconnection is not detected in step S94, the process returns to step S76, so that the entry code transmission operation can be performed again.

In step S96, it is checked whether or not the temporary entry code transmitted from step S76 to step S94 is successful. If it is successful, the process proceeds to step S98, to that effect is reported to the vehicle 3, and the flow is terminated. The vehicle 3 in FIG. 1 includes a telephone communication unit (not shown), and can communicate with the first telephone communication unit 18 or the second telephone communication unit via a telephone line. The telephone communication unit of the vehicle 3 is connected to the vehicle control unit 38 in the same manner as the first telephone communication unit 18 is connected to the first portable control unit 6, and requires information exchange performed by the telephone communication unit. Accordingly, transmission to each part of the vehicle 3 is possible. The report to the vehicle that the temporary entry code has been successfully transmitted in step S98 is usually performed by digital signal communication through such a telephone line. If short-distance communication is possible, the first portable short-range communication unit 20 or This is performed by transmitting a digital signal from the second portable short-range communication unit 36 to the vehicle short-range communication unit 48. If communication to the vehicle cannot be established even after a predetermined time has elapsed and reporting to the vehicle that the substitute operation has been requested cannot be made, the report is temporarily abandoned in step S98, and the flow ends. Such a case occurs when the vehicle is placed in a parking lot outside the wireless communication range.

If the success of the temporary entry code transmission cannot be confirmed in step S96, the flow is terminated as it is. This corresponds to the case where the line is disconnected from step S76, step S80, or step S90 to step S94. If the line cannot be connected in step S74, the flow is immediately terminated.

In the first embodiment described above, the entry code is superimposed on the audio signal and handled as audio data when the entry code is transmitted / received. This is because the request for the substitute operation is a voice exchange with the substitute operator. In order to prevent entry code leakage or forgery of the vehicle due to counterfeiting, it is possible to transmit / receive the entry code unless a voice line for this purpose is connected. In addition, with this configuration, it is possible to transmit and receive entry codes in parallel with voice communication with the agent. However, the implementation of the present invention is not limited to this, and the entry code may be communicated by a data communication system such as the Internet other than the voice line. In this case, in order to prevent the entry code from being leaked or forged, security measures are taken as appropriate when sending and receiving it.

FIG. 6 is a flowchart showing functions of the first portable control unit 6 from the substitute driver registration to the entry code transmission of FIG. 5 performed as a premise of the entry code transmission to the substitute driver in FIG. The operation starts when the substitute operation operation or the substitute driver registration operation is performed in step 8. In addition, this substitute driving | operation operation is comprised so that not only the substitute driving | operation request | requirement to a substitute driver | operator but the rental of a private vehicle etc. to a friend etc. may be responded. When the flow starts, it is checked in step S102 whether there is a registered substitute driver. If there is no registered substitute driver, the process proceeds to step S104. This is because, even if the flow starts for the substitute operation, if there is no registered substitute driver, the substitute driver must be registered first.

In step S104, it is checked whether or not there has been an input operation that specifically designates a substitute driver to be registered. If this operation is not detected within a predetermined time, the process proceeds to step S106, and a list of unregistered substitute drivers is displayed. . This list is provided by the agency driving business, and is provided to the mobile phone in advance through the Internet or the like together with the profile of the agency driver such as address, age, and gender. The flow proceeds to step S108 while continuing this list display, and it is checked whether or not an operation for selecting a substitute operator to be registered from the list display is performed within a predetermined time from the start of the list display. If this operation is not detected within a predetermined time, the process proceeds to step S110, where a substitute driver automatic designation process for selecting a substitute driver to be registered from a list display according to a predetermined rule is performed, and the process goes to step S112.

As described above, when there is no registered substitute driver, if no operation is performed for a predetermined time after the flow starts, the substitute driver to be automatically registered is designated and the process proceeds to step S112. be able to. Therefore, if the user does not care about who is registered as the substitute driver, even a user who does not know the troublesome procedure can automatically proceed with the registration of the substitute driver necessary for the substitute operation request. On the other hand, when there is an input operation that specifically designates the substitute driver to be registered in step S104, the process proceeds to step S114, the substitute driver designation as executed is executed, and the process goes to step S112. In addition, when a selection operation from the list display is detected in step S108, the process proceeds to step S114, the substitute driver to be registered as specified is executed, and the process proceeds to step S112.

In step S112, it is checked whether or not there is a problem with the car insurance for the substitute driver to be registered in step S110 or step S114 to drive the vehicle. If a problem that the driver who is going to register falls under the waiver of automobile insurance and cannot respond to an accident or the like is detected in step S112, the process proceeds to step S116 to automatically join the temporary insurance and then to step S118. Transition. This temporary insurance covers, for example, car insurance for a surrogate driver registered for a short period such as 3 days. On the other hand, when it is confirmed in step S112 that the insurance is OK, the process directly proceeds to step S118. In step S118, it is checked whether or not a new substitute driver to be registered in step S114 or step S110 is specified. If there is a match, the process proceeds to step S120. In step S120, registration processing of the substitute driver that should be registered is performed, and the process proceeds to step S122. On the other hand, when the new designation of the substitute driver is not detected in step S118, the process directly proceeds to step S122. The reason why such a case occurs will be described later.

In step S122, it is checked whether or not an operation for expanding the range of conditions covered by car insurance has been performed. If applicable, the process proceeds to step S124 to perform an insurance contract change process, and the process proceeds to step S126. On the other hand, when the insurance condition expansion operation is not detected in step S122, the process directly proceeds to step S126. Here, it supplements about said insurance condition expansion operation. If it is detected in step S112 that the insurance is not OK, the temporary insurance is added as an emergency measure for the time being in step S116. This is an expansion operation of insurance conditions such as cancellation. While the participation in temporary insurance is performed automatically, the normal expansion of insurance conditions is performed manually.

When it is detected in step S102 that there is a registered substitute driver, the process proceeds to step S128 to check whether the flow is started by the substitute driver registration operation. And if applicable, it transfers to step S104 and the process for newly registering a substitute driver is performed according to the flow demonstrated above.

On the other hand, when the detection that the flow of FIG. 6 is not started by the substitute driver registration operation is performed in step S128, this corresponds to the case where the flow starts by the substitute operation and there is a registered substitute driver. . In this case, the process basically proceeds to step S126, but step S130 is provided before that, and it is checked whether or not the car insurance is OK. If OK, the process directly proceeds to step S126. If there is a problem, the process proceeds to step S116. The reason that step S130 is provided is that the insurance condition expansion operation assuming the driver has not been performed in the past and the temporary participation that has been automatically joined in the past even in the case of the substitute driving operation assuming the registered proxy driver This is because insurance may have expired. Therefore, in this case, as already described, first, after automatically joining the temporary insurance again in step S116, the process proceeds to a check of the insurance condition expansion operation in step S122. In this case, step S120 is skipped because it is not a new designation of the substitute driver.

In step S126, it is checked whether or not the flow in FIG. 6 has been started by a substitute operation. Then, if applicable, the process proceeds to step S132, and it is checked whether or not a substitute driver designation operation has been performed. The content of step S132 is a process for checking whether or not an operation for selecting a substitute driver is performed within a predetermined time after the display after a list is displayed when there are a plurality of registered substitute drivers. It becomes. If no nomination operation is performed within a predetermined time from the start of list display, the process proceeds to step S134, where an automatic driver is automatically designated based on a predetermined priority order, and the process proceeds to step S136. On the other hand, if it is detected in step S132 that a nomination operation has been performed, the process proceeds to step S138, the nomination is performed as operated, and the process proceeds to step S136. If there is only one registered substitute driver, the process immediately proceeds from step S132 to step S134, where automatic nomination processing is performed and the process proceeds to step S136.

In step S136, the temporary keyless entry code is transmitted to the designated substitute driver, and the flow ends. Details of step S136 are as described in FIG. As described above, the flow of FIG. 6 is the automatic designation of the substitute driver in step S110, even if the substitute driver simply performs the substitute operation in the unregistered state and does not operate anything thereafter, Temporary entry code transmission processing to the designated substitute driver in step S136 through automatic participation in the temporary car insurance in S116, automatic registration of the substitute driver in step S120, and further, automatic substitution of the substitute driver in step S134 Is executed. Therefore, even a user who does not know the detailed operation procedure for the substitute driver or the substitute operation request can easily request the substitute operation. This is suitable for situations where it is necessary to request a surrogate surrogate operation after drinking. In addition to the above, the function according to the flow of FIG. 6 can also cope with a manual operation based on various requests of the user.

FIG. 7 is a basic flowchart showing the operation of the vehicle control unit 38 in the vehicle 3 of FIG. 1, and starts with energization from the vehicle battery. When the flow starts, it is checked in step S142 whether or not there is a problem in each part of the vehicle. If there is an abnormality, the corresponding process in step S144 is entered, and if the corresponding process is completed, the process proceeds to step S146. If it is confirmed in step S142 that each part of the vehicle is OK, the process proceeds directly to step S146.

In step S146, the vehicle control unit 38 checks whether a keyless entry code transmission for opening and closing the door has been detected. If there is a detection, the process proceeds to step S148 to authenticate it, and the keyless entry code management unit 52 checks whether the detection code matches the reference code or the temporary reference code held in the keyless entry code management unit 52. Let If the detection result matches either one, the process proceeds to step S150 as authentication OK, and the door lock is unlocked or locked. Then, control goes to a step S152. On the other hand, if there is no detection in step S146 or if the detection result in step S148 cannot be authenticated, the process directly proceeds to step S152. Here, the “reference code” corresponds to an entry code transmitted from the vehicle owner himself / herself, and is a reference entry code held on the vehicle side in order to authenticate this. On the other hand, the “temporary reference code” corresponds to the temporary entry code transmitted from the substitute driver or the vehicle lender, and the temporary entry code for reference held on the vehicle side to authenticate it. It is. The reference code and the temporary reference code are frequently updated according to different management procedures and managed together with the update date, details of which will be described later.

In step S152, it is checked whether or not a keyless entry code transmission for releasing the engine lock has been detected. If there is a detection, the process proceeds to step S154 to authenticate it, and the keyless entry code management unit 52 checks whether the detection code matches the reference code or the temporary reference code held in the keyless entry code management unit 52. Let If the detection result matches either one, the authentication is OK and the process proceeds to step S156 to release the engine lock. Then, control goes to a step S158. On the other hand, if there is no detection in step S152 or if the detection result in step S154 cannot be authenticated, the process directly proceeds to step S158.

In step S158, code management processing is performed. This is processing for changing the entry code in cooperation with the mobile phone in order to prevent theft of the vehicle due to leakage of the entry code, which will be described in detail later. Next, in step S160, the presence / absence of a driving operation is detected. If an operation is detected, the process proceeds to step S162, where the driving process is performed as in the operation, and the process returns to step S142. On the other hand, when the driving operation is not detected in step S160, the process directly returns to step S142. In the following flow, steps S142 to S162 are repeated to deal with various situations relating to the vehicle.

FIG. 8 is a block diagram showing a second example of the keyless entry system according to the embodiment of the present invention. The second embodiment basically has the same configuration as that of the first embodiment shown in FIG. 1, but the first mobile phone 102 is placed on the cradle 106 of the vehicle 104 so that the first mobile phone 102 is connected to the first through the mobile connector 108. A configuration for charging the mobile phone 102 and exchanging signals between the two is added. In the following, the second embodiment will be described with a focus on this added configuration, and common parts to those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted. Further, in the second embodiment of FIG. 8, the second mobile phone 2 and the parking lot 4 as shown in FIG. 1 are not shown, but this is omitted for the sake of simplicity. The system includes a second mobile phone 2 and a parking lot 4 similar to those in the first embodiment, and these points are not different from those in the first embodiment. In FIG. 8, the symbol indicating wireless communication is also omitted, but wireless communication between the first portable short-range communication unit 20 and the vehicle short-range communication unit 48 and the keyless entry communication unit of the first mobile phone 102. The wireless communication between the vehicle 28 and the keyless entry communication unit of the vehicle 104 is not different from the first embodiment.

In FIG. 8, the power source 110 of the vehicle 104 supplies power to each part of the vehicle. Although not described, the power source 110 also exists in the vehicle 3 of the first embodiment. The cradle 106 is configured to place the bottom of the first mobile phone 102 and has a power contact 112 and a signal contact 114. The power contact 112 supplies the charging power from the power source 110 to the outside. The signal contact 114 is connected to the vehicle control unit 38 and serves as an interface for signal exchange with the outside. The mobile-side connector 108 is provided at the bottom of the first mobile phone 102, and contacts the power contact 116 that contacts the power contact 112 of the cradle 106 and the signal contact 114 of the cradle 106 when the first mobile phone is placed on the cradle 106. The signal contact 118 is provided. The power contact 116 is connected to the main power supply 24 and receives the power supplied from the vehicle 104 to charge the main power supply 24. The signal contact 118 is connected to the first portable control unit 6 and serves as an interface for signal exchange with the outside.

Various information can be exchanged between the mobile phone 102 and the vehicle 104 between the signal contact of the cradle 106 and the signal contact 118 of the portable connector 108. For example, the image information captured by the camera unit 22 and stored in the storage unit 12 can be moved or copied to the storage unit 44 of the vehicle 104 having a larger storage capacity. The image information input to the storage unit 44 in this way can be viewed on a car navigation screen (not shown) mounted on the vehicle 104. Further, the image information in the storage unit 12 can be directly viewed on the car navigation screen. Further, it is possible to set the destination of the car navigation by sending the sightseeing information obtained by the first mobile phone 102 via the Internet to the vehicle 104. Further, every time the first mobile phone 102 is placed on the cradle 106 of the vehicle 104 for charging, communication for updating the keyless entry code is performed between the signal contact 114 and the signal contact 118, and leakage of the keyless entry code It can be a countermeasure against counterfeiting. Details thereof will be described later. In addition, although the cradle 106 and the portable connector 108 in the second embodiment are configured by a contact system, this may be configured by a contactless system that employs power transmission by electromagnetic induction and signal transmission by weak radio waves. . Even in such a contactless system, the first mobile phone 102 is configured to be placed on the cradle 106.

Further, the second embodiment of FIG. 8 has a telephone line communication unit 120. This has the same configuration as the first telephone function unit and the first telephone communication unit 18 of the first mobile phone 102, and can perform wireless communication with the first mobile phone via a telephone line. it can. The telephone line communication unit 120 can perform voice conversation communication as a vehicle phone, but the main purpose of the configuration is data communication when transmitting a keyless entry code to the first mobile phone and accessing the Internet. Such a telephone line communication unit 120 is also provided in the first embodiment of FIG. 1, but is not shown in FIG. The basic flowchart of the vehicle in FIG. 7 can be commonly applied to the vehicle control unit 38 in the vehicle 104 in the second embodiment as described above.

FIG. 9 is a flowchart showing details of the code management processing in step S158 of FIG. 7, and is applicable to both the first embodiment of FIG. 1 and the second embodiment of FIG. Although some of the functions related to cradle placement are specific to the second embodiment, processing that does not fall under this is simply skipped. There is no problem. In addition, if necessary, the redundant steps may be omitted and applied to the first embodiment.

When the flow starts, it is checked whether or not the time at which the code management process is started falls within a time range of 0 to 5 seconds per minute based on a clock function built in the vehicle control unit 38. If so, an entry code random number is generated in step S174, and the update entry code register is overwritten in step S176 based on the result, and the process proceeds to step S178. On the other hand, if not applicable in step S172, the process directly proceeds to step S178. Note that the flow in FIG. 9 is a part of the flow in FIG. 7, and the flow in FIG. 7 is repeated, so that the above-described step S172 is passed each time. The probability that the time at this time falls within the time range from 0 seconds to 5 seconds per minute is 1/12, but if the frequency of passing through step S172 is 12 times per minute on average, it is 1 on average per minute. From step S172 to step S174, therefore, the update entry code register is rewritten based on the random number at an average of once per minute in step S176. In the flow of FIG. 7, if there is a process in step S144, step S162, or the like, the frequency of passing the code management in step S158 decreases, but the entry code is updated during such a process to prepare for theft. There is no need to do so. Conversely, when the vehicle is parked and there is no processing, the processing in step S158 is repeated with high frequency, so that the rewriting of the trust entry code register in step S176 in FIG. 9 is also performed with high frequency.

In step S178, it is checked whether or not the reference code update date is the current date. If it is not that day, the process proceeds to step S180. This is the case when the reference code is old and updated before the previous day. In step S180, the latest update entry code is read from the update entry code register, and the reference entry code held in the keyless entry code management unit 52 is updated. Next, in step S182, the same data as the updated reference entry code is wirelessly transmitted to the vehicle owner's mobile phone as an updated entry code. This transmission is first attempted by the vehicle short-range wireless communication unit 48, and if this is not possible, it is performed by the telephone line communication unit. Then, in step S184, it is checked whether or not a predetermined time has elapsed after transmission. If it has not passed, it is checked in step S186 whether or not a report indicating that the entry code update has been completed is received from the mobile phone of the vehicle owner. The mobile phone automatically performs everything from update to completion report transmission based on the receipt of the entry code. Therefore, even if the owner does nothing, the entry code on the mobile phone side is automatically updated.

If reception of the update completion report cannot be confirmed in step S186, the update entry code is retransmitted in step S178. Thereafter, steps S182 to S186 are repeated until a predetermined time elapses, and the reception of the update completion report is awaited. When reception of the update completion report is confirmed in step S186, the process proceeds to step S188. On the other hand, if it is confirmed in step S184 that the predetermined time has passed without receipt of the update completion report, the transmission is temporarily stopped and the process proceeds to step S188. If the reference entry code update date is the current day in step S178, the process proceeds to step S190 to check whether the same data as the reference entry code has been transmitted to the vehicle owner. If it has been transmitted, the process proceeds to step S188. In this way, each time the date changes, the reference entry code is updated in step S180, and this is transmitted to the mobile phone. If the data has not been transmitted in step S190, the process proceeds to step S182 to execute transmission. This corresponds to a case where data transmission to the vehicle owner immediately after the update of the reference entry code cannot be executed.

In step S188, it is checked whether or not the vehicle owner's mobile phone is placed on the cradle 106 of the vehicle 104. If applicable, the process proceeds to step S192 to perform update control processing to the latest communication entry code. When the vehicle owner's mobile phone is placed on the cradle 106, the mobile phone functions as a drive under the control of the vehicle control unit through the signal contacts 114 and 118, so in step S192 the update entry code for the mobile phone is Communication and confirmation can be performed directly in real time. When the process is completed, the process proceeds to step S194, and the reference entry code held in the keyless entry code management unit 52 on the vehicle side is updated corresponding to the above, and the process proceeds to step S196. On the other hand, if it is not detected in step S188 that the vehicle owner's mobile phone is placed on the cradle 106, the process directly proceeds to step S196. Thus, every time the vehicle owner's mobile phone is placed on the cradle 106 of the vehicle 104, the mobile phone side entry code and the corresponding vehicle side reference entry code are updated in steps S192 and S194. Is called.

In step S196, a temporary entry code management process is performed. Steps S178 to S194 relate to the management of entry codes related to keyless entry by the vehicle owner's mobile phone, while step S196 relates to management of temporary entry codes related to keyless entry by the mobile phone of the substitute driver or vehicle lender. Is. Details thereof will be described later.

FIG. 10 is a flowchart showing details of the temporary entry code management process in step S196 of FIG. When the flow starts, it is checked whether or not the temporary reference entry code is held in the vehicle keyless entry code management unit 52 in step S202. If there is no hold, the data is read from the update entry code register and is newly input to the keyless entry code management unit 52 and held. Next, in step S206, the same temporary entry code as that newly input is transmitted to the mobile phone of the vehicle owner. This is to make the temporary entry codes coincide on the vehicle side and the mobile phone side of the vehicle owner. The contents of step S206 are in accordance with steps S182 to S186 of FIG. 9, and if the transmission is completed or if the transmission has not been completed and the predetermined time has elapsed, the process proceeds to step S208.

On the other hand, if it can be confirmed in step S202 that the temporary reference entry code is already held in the keyless entry code management unit 52, the process proceeds to step S210, and it is checked whether or not the code has already been transmitted to the vehicle owner. If it has not been transmitted, the process proceeds to step S206 to enter a process for transmitting it. The case where it has not been transmitted corresponds to the case where the transmission process in step S206 is not successful after the temporary reference entry code is newly input in step S204.

In step S208, a report to the effect that the substitute operation request has been made is transmitted from the mobile phone of the vehicle owner, and it is checked whether this is received by the vehicle. If it has been received, the process proceeds to step S212, and it is checked whether 24 hours have elapsed since the substitute operation request report was received. If it has elapsed, the process proceeds to step S214, and it is checked whether or not the temporary entry code updated after 24 hours has been transmitted.

Further, if the updated temporary entry code has not been transmitted, the process proceeds to step S216, where data is read from the update entry code register and the temporary reference entry code held in the keyless entry code management unit 52 is updated. And the process which transmits the updated temporary entry code to a vehicle owner's mobile telephone is performed by step S218. The contents of step S218 are also in accordance with steps S182 to S186 of FIG. 9, and the flow ends when the transmission is completed or when a predetermined time has elapsed since transmission has not been completed. If the flow is terminated without completing transmission, the code management process of step S158 is entered again in the repetition of the basic flow in FIG. 7, and the temporary entry code management process of step S196 is reached. By executing step S218 from S212, an attempt is made to transmit the updated temporary entry code to the vehicle owner.

On the other hand, if 24 hours have not elapsed since the reconsideration operation request report was received in step S212, the flow is immediately terminated. Also, if the updated temporary entry code has already been transmitted in step S214, the flow is immediately terminated. As described above, when the substitute driving request report is received, the temporary entry code is updated after the elapse of 24 hours, so the temporary entry code transmitted from the vehicle owner's mobile phone to the driving agent is invalid. Become. As a result, even if an unexpected situation occurs in which the temporary entry code transmitted to the outside leaks, entry into the vehicle using the temporary entry code becomes impossible after 24 hours. On the other hand, when a substitute operation request is made, it is guaranteed that the temporary entry code sent to the substitute driver at that time will not be updated for 24 hours, so that the temporary entry code is changed without permission and the substitute driver cannot enter. This does not occur. On the other hand, in the case of the entry code for the vehicle owner himself / herself, when the date is changed as in steps S178 and S180 of FIG. 9, or the mobile phone is cradle of the vehicle as in steps S188 to S194 of FIG. It will be changed as appropriate when it is placed on.

On the other hand, when the substitute operation request report has not been received in step S208, the process proceeds to the safety process in step S220. This safety process assumes that the report has not arrived at the vehicle due to the communication environment even though the substitute operation is requested, and is automatically and temporarily performed at a predetermined time as in steps S212 to S216. Instead of updating the reference code, the entry code is updated in accordance with a predetermined procedure in consideration of driving safety to prevent the entry code from being leaked or forged by the forgery.

FIG. 11 is a flowchart showing details of the safety process in step S220 in FIG. When the flow starts, it is checked whether or not a case has occurred in which data for which the keyless entry is performed and the authentication is OK corresponds to the temporary authentication entry code. That is, it is checked whether a keyless entry with a valid temporary entry code has been performed. If keyless entry has not been made at this time, or if keyless entry has been made by the mobile phone of the vehicle owner, this does not correspond to step S232. In such a case, it is not necessary to perform safety processing, so the flow is immediately performed. finish.

On the other hand, if keyless entry with a valid temporary entry code has been made, the process proceeds from step S232 to step S234, and it is checked whether or not the owner's mobile phone is within a communicable range. If it is within the communication range, a substitute operation request confirmation process is performed in step S236. This has the same significance as the substitute driving request report process to the vehicle in step S98, but the report was made from the mobile phone side to the vehicle in step S98, whereas in step S236, the vehicle side changed to the mobile phone side. It becomes a form to inquire. Thus, for example, even if the vehicle is placed in a parking lot outside the communication range and it is not possible to report to the vehicle that a substitute operation request is being made in step S98, the substitute driver moves the vehicle. Thus, if the vehicle enters the communication range, steps S234 to S236 function to automatically perform processing for the vehicle to obtain information on the substitute operation request. Then, in the next step S238, it is checked whether or not it is confirmed that the substitute operation request has been made, and in the case of OK, it is not necessary to perform the safety process, so the process proceeds to step S258, and the substitute operation request report has been received. End the flow as the same treatment as.

On the other hand, when the substitute operation request cannot be confirmed in step S236, the process proceeds from step S238 to step S240, and a notification is made. This announcement announces in advance to the vehicle driver that entry into the vehicle or engine cannot be started if a predetermined condition described later is satisfied. This is to prevent unforeseen circumstances due to the inability to do so. Further, when a predetermined condition described later is satisfied and the vehicle cannot be entered or the engine cannot be started, the reason is notified to the driver. In step S242, it is checked whether or not the engine has been started with the temporary keyless entry code. If the engine has not yet been started, the safety process is not entered and the flow is immediately terminated.

On the other hand, when it is detected in step S242 that the engine has been started, the safety process is subsequently performed, and it is determined whether the engine has been started and the number of times elapsed since the first engine start has already been started. Check in step S244. If not started, the process proceeds to step S246 to start counting the number of times the engine has been started and the time elapsed since the first engine start, and to step S248. On the other hand, when it is detected in step S244 that the start count has already been started, the process proceeds directly to step S248. In step S248, it is checked whether or not the number of times the engine has been started has reached a predetermined number (for example, 3 times). If not yet reached, a predetermined time (for example, 3 hours) has elapsed since the first engine start in step S250. Just check. If none of them apply, the flow ends.

On the other hand, when it is detected that the number of times the engine is started in step S248 reaches a predetermined number, or in step S250 that a predetermined time has elapsed since the first engine start, the process proceeds to step S252, and after the first engine start It is checked whether or not the updated temporary entry code has been transmitted to the vehicle owner. If it has not been transmitted, the process proceeds to step S254 to update the temporary reference entry code. This makes it impossible to enter the vehicle or start the engine with the original temporary entry code thereafter. As a result, illegal actions such as leakage of entry codes or theft of vehicles due to counterfeiting are prevented while preventing dangers when a genuine substitute driver is driving the vehicle without being able to report a substitute operation request to the vehicle. .

When the temporary reference entry code is updated in step S254, the process proceeds to step S256, where the updated temporary entry code is transmitted to the mobile phone of the vehicle owner. The contents of step S256 are also in accordance with steps S182 to S186 of FIG. 9, and if the transmission is completed or if the transmission has not been completed and the predetermined time has elapsed, the flow is terminated. Note that in the process of handling the substitute operation request report in step S258, even if the temporary reference entry code has been updated once via step S254, the temporary reference entry code at the time when the engine is started in step S242. Then, the temporary entry code is managed by the processing from step S212 to step S218 in FIG. Therefore, even if entry is once disabled by step S254, when step S258 is reached from step S236 through step S238, keyless entry with the original temporary entry code is performed unless 24 hours have passed since the substitute operation request. The state that can be restored.

FIG. 12 relates to a third example of the keyless entry system according to the embodiment of the present invention. The third embodiment is basically the same as the first embodiment, and details of the configuration can be understood with reference to FIG. The third embodiment can be similarly implemented in the second embodiment of FIG. The third embodiment differs from the first and second embodiments in that the first portable control unit 6 in FIG. 1 or FIG. 8 is information on the parking position of the vehicle and the position information of the vehicle owner in the substitute driving request. This is a feature that adds a function to handle images. FIG. 12 is a flowchart showing the function of the first portable control unit 6 when a telephone call operation to a substitute driver registered in advance is performed by the telephone operation unit 8 as in FIG. . When the flow starts, a code temporarily stored as the current position of the vehicle owner who owns the first mobile phone 1 is displayed in step S262. This vehicle owner temporary position code is stored as the latest current position of the vehicle owner, details of which will be described later.

Next, in step S264, it is checked whether an operation for the vehicle owner to approve the displayed vehicle owner position code has been performed within a predetermined time from the display. When the vehicle owner carrying the first mobile phone 1 requests the substitute driving, if the vehicle owner waits for the vehicle forwarded by the substitute driver at the position indicated by the stored vehicle owner temporary position code. Therefore, step S262 and step S264 are provided, and it is confirmed whether the vehicle owner is willing to wait for the substitute driver at the displayed position. When the approval operation is detected, the process proceeds to step S266, where the process of approving the temporary code displayed in step S262 as the vehicle owner position code is performed, and the process proceeds to step S268. On the other hand, when the approval operation is not detected within the predetermined time in step S264, the process directly proceeds to step S268. In this case, step S268 is reached with no approved vehicle owner position code.

In step S268, a call is made to the registered driver's telephone number in the same manner as in step S72 of FIG. 5, and it is checked in step S270 if the line is connected within a predetermined time. When the connection is confirmed, the process proceeds to step S272, and it is checked whether or not an operation for transmitting the entry code is performed by the telephone operation unit 8. When it is confirmed that this operation has been performed, the process proceeds to an authentication process in step S274. This authentication process is the same as step S78 to step S84 in FIG. 5, and is a process of authenticating the substitute driver to which the line is connected by transmitting an authentication request signal and detecting an authentication reply signal. Note that, in the authentication process in step S274, if the authentication signal is not detected even after a predetermined time has elapsed after the transmission of the authentication request signal in the same manner as in FIG. Although it can proceed directly, the illustration is omitted in FIG.

Further, in the authentication processing in step S274, the transmission of the authentication request signal and the exchange of the authentication reply signal are performed in the same manner as in FIG. 5, but the implementation of the present invention is not limited to this. This may be done by communication. If the substitute driver can be authenticated in step S274, the process proceeds to step S276 similar to step S86 in FIG. 5 and the temporary entry code is read from the keyless entry code storage unit 30.

In the next step S278, it is checked whether or not the parking code indicating the parking position of the vehicle requesting the substitute operation is stored in the storage unit 12. If there is a storage code, it is read in step S280 and the process proceeds to step S282. On the other hand, if no parking code is detected in step S278, the process directly proceeds to step S282. In step S282, it is checked whether or not the vehicle owner position code approved in step S266 is stored in the storage unit 12, and if it is stored, it is read in step S284 and the process proceeds to step S286. On the other hand, if the approved vehicle owner position code is not detected in step S282, the process directly proceeds to step S286.

In step S286, transmission processing for transmitting the code read in steps S276, S280, and S284 as described above is performed. If all of these are transmitted, the surrogate driver can drive the vehicle with the temporary entry code, and can also obtain information on where to pick up the vehicle and where to send it. Of course, if there is no read code according to one or both of step S280 and step S284, those codes will not be transmitted. In this case, the substitute driver appropriately contacts the vehicle owner to obtain information necessary for vehicle delivery. Information on the parking position and the current position of the vehicle owner can be obtained verbally by telephone at the time of proxy request, but can be supplemented as appropriate by subsequent mutual communication.

The read code transmission process in step S286 is the same as that in steps S88 to S92 in FIG. 5, and is for reliably transmitting the read code by transmitting the read code and detecting the reception confirmation signal. In the read code transmission process in step S286 as well as in FIG. 5, if a reception confirmation signal is not detected even after a predetermined time has elapsed after the read signal is transmitted, a process for inquiring line disconnection in later-described step S288. However, in FIG. 12, the illustration is omitted. Also, in the transmission processing in step S286, the transmission of the read code and the exchange of the reception confirmation signal are performed in the same manner as in FIG. 5, but the implementation of the present invention is not limited to this, and normal data This may be done by communication.

When the read code transmission process in step S286 is completed, the process proceeds to step S2288 similar to step S94 in FIG. 5 to check whether or not a line disconnection operation has been performed. If the line is disconnected, the process proceeds to post processing in step S290. On the other hand, if a line disconnection operation is not detected in step S288, the process returns to step S272, and thereafter steps S272 to S288 are repeated.

The post-processing in step S290 is the same as that in steps S96 and S98 in FIG. 5, and checks whether or not the transmission of the read code is successful, and if successful, reports that fact to the vehicle 3. . Note that the flow proceeds to the next step S292 in the same manner as the flow proceeds to the end in FIG. 5 regardless of the success of the transmission of the vehicle readout code. Note that if the line cannot be connected in step S270, the flow also proceeds to step S292. Step S292 is a process of canceling the vehicle owner position code when the vehicle owner position code is approved in step S266. The approval in step S266 is only when requesting a substitute operation, and it is rare that the owner of the mobile phone 1 stays in the same position indefinitely. That is, the approval made in step S266 is no longer used after notifying the substitute driver in the substitute operation request, and is unnecessary even when the substitute operation request cannot be made. Therefore, in order to avoid subsequent confusion, step S292 is provided. If the vehicle owner position code has been approved in any case, the flow is terminated after canceling this.

FIG. 13 relates to the third embodiment and is a flowchart showing the function of the first portable control unit 6 for obtaining the parking code handled in step S280 of FIG. The flow in FIG. 13 starts by turning off the engine of the vehicle. First, in step S302, it is checked whether the parking code is stored in the storage unit 12 in FIG. If there is a memory, the process proceeds to step S304 to communicate with the vehicle. After storing the parking code, it is checked whether the engine has been turned off after traveling for a predetermined distance (for example, 50 m).

If it is detected in step S304 that the vehicle has traveled more than a predetermined distance, the process proceeds to step S306, the parking code stored in the storage unit 12 is deleted, and the process proceeds to step S308. On the other hand, when it is determined in step S302 that the parking code is not stored, the process directly proceeds to step S308. If it is detected in step S304 that the engine key has not been turned off after traveling for a predetermined distance or more, the process proceeds directly to step S306. In this case, the stored parking code is maintained. The above processing is intended to delete a parking code that is no longer meaningful as information in order to avoid confusion.

In step S308, the first portable short-range communication unit 20 receives a code of a garage that is regularly used, such as a garage at home or a garage at a commuting destination (or may be a parking lot, but both are hereinafter collectively referred to as a garage). Check if it was done. In the case where the short distance communication unit 62 is provided in the garage like the parking lot 4 or the like, this is detected when the vehicle 3 enters the near field communication area and parks, and the garage is specified. This is possible when it is configured to transmit a code. If not, the process proceeds to step S310, and it is checked whether or not a code for identifying a temporary garage has been received by the first short-range communication unit 20. This is possible even when the temporary garage is provided with a short-range communication unit similar to the stationary garage. It is desirable that such garage codes are managed in a unified manner by a common system.

If it does not correspond to step S310, it will progress to step S312 and will check whether the vehicle GPS position code was received by the GPS part 16 of the 1st mobile telephone 1 at the time of turning off an engine. In the above description, the position data acquired by the GPS unit 16 of the first mobile phone 1 is the vehicle GPS position code. This is because the holder of the first mobile phone 1 is driving the vehicle 3. This is because the position of the first mobile phone 1 may be regarded as the position of the vehicle 3. Instead of this, data received by the GPS unit 46 of the vehicle 3 may be used as a vehicle GPS position code and relayed from the vehicle short-range communication unit 48 to the first portable short-range communication unit 20. In any of the above cases, if the vehicle GPS position code is received by the first mobile phone 1, the process proceeds to step S314, and the received code is overwritten and stored on the old code in the storage unit 12 as the parking position code. End the flow.

On the other hand, when it is detected in step S308 that the steady garage code has been received, the process proceeds to step S316, and arrival transmission processing is performed. This transmission is automatically performed to the home or the company by the first telephone communication unit 18 (if possible, the first portable short-range communication unit 20). It can be used as. By performing transmission from the mobile phone 1 side in this way, it is possible to provide a simple function of automatically transmitting a steady garage code only by providing a short-range communication unit on the steady garage side. When the arrival transmission process is completed, the process proceeds to step S318, the garage code in the storage unit 12 is overwritten and updated with the received code, and the process proceeds to step S320. Further, when it is detected in step S310 that the temporary garage code is received, the process proceeds to step S318, the garage code in the storage unit 12 is overwritten and updated with the received code, and the process proceeds to step S320.

The garage code stored in step S318 functions as a parking code complementary to the parking position code stored in step S314. That is, the garage code specifies a registered parking lot name and the like, and is standardized and managed. Therefore, the garage code is suitable for setting as a car navigation destination or the like as will be described later. On the other hand, although the parking position code is not suitable for standardization, it is suitable for specifying a position where the vehicle is actually parked in a large parking lot where only the parking lot name can be specified only by the garage code.

In step S320, in addition to the garage code stored in step S318, it is checked whether a code specifying a parking position in the garage has been received. Such a garage position code is transmitted from near-field communication on the garage side under management by a system for each garage, and can identify, for example, a parking position number.
If such a garage position code is received, the process proceeds to step S314, the received code is overwritten and stored in the storage unit 12, and the flow ends. On the other hand, if it is not detected in step S320 that the garage position code has been received, the process proceeds to step S322 to check whether a code indicating the relative position of the vehicle in the garage has been received. Such a relative position code is obtained by a plurality of short-range communication units such as a parking lot first short-range communication unit 62 and a parking lot second short-range communication unit 64 each sharing a communication area, as in the parking lot 4 of FIG. It can be obtained at the garage where it is arranged. That is, radio wave analysis of which short-range communication unit in the parking lot 4 can communicate with the first mobile phone 1 or a triangle between the plurality of short-range communication units in the parking lot 4 and the first mobile phone 1 Based on the radio wave analysis of the communication, the parking lot control unit 58 determines the relative position of the first mobile phone 1 in the parking lot 4 and transmits it to the first portable short-range communication unit 20 as a relative position code. If such a relative position code has been received, the process proceeds to step S314, the received code is overwritten and stored in the storage unit 12, and the flow ends.

If it is not detected in step S322 that the relative position code has been received, the process proceeds to step S324 to check whether the vehicle GPS position code has been received. When the vehicle GPS position code is received, the process proceeds to step S314, where the received code is overwritten and stored in the storage unit 12, and the flow ends. On the other hand, if it is not detected in step S324 that the vehicle GPS position code has been received, the flow ends at that point. In this case, only the garage code stored in step S318 becomes the parking code, and the parking position code is not stored.

If the vehicle GPS position code is not received by the GPS unit 16 of the first mobile phone 1 when the engine is turned off in step 312, it means that the vehicle is out of the GPS communication range when the engine is turned off. . In this case, the process proceeds to step S326, and it is checked whether or not the latest GPS information immediately before going out of the communication range out of the GPS information accumulated in the vehicle in the course of navigation is received as a reference GPS position code from the short-range communication unit of the vehicle. . If it is received, the process proceeds to step S328, where it is stored as a reference GPS position code, and the flow ends. Strictly speaking, such a reference GPS position code does not indicate the parking position of the vehicle, but is GPS information immediately before going out of the GPS communication range before reaching the parking position. Since it is information, it can be used as reference information for vehicle search.

FIG. 14 relates to the third embodiment and is a flowchart showing the function of the first portable control unit 6 for obtaining the vehicle owner temporary position code displayed in step S262 of FIG. The flow in FIG. 14 is performed when the first portable short-range communication unit receives a spot code started from a predetermined set time (for example, 30 minutes) or from a predetermined spot (for example, a facility, a restaurant, etc.), or When the GPS unit 16 of the first mobile phone 1 receives new GPS information, it automatically starts an interrupt. Also, an interrupt is generated when an operation for manually inputting a position code is performed by the telephone operation unit 8, and the flow of FIG. 14 is started.

When the flow starts, in step S332, it is checked whether or not the vehicle owner temporary position code is stored in the storage unit 12. If it is stored, the process proceeds to step S334, and it is checked whether or not a predetermined time (for example, 12 hours) has elapsed after the code is stored. If it is detected in step S334 that the predetermined time has elapsed, the process proceeds to step S336, the vehicle owner temporary position code stored in the storage unit 12 is deleted, and the process proceeds to step S338. On the other hand, when it is determined in step S332 that the vehicle owner temporary position code is not stored, the process directly proceeds to step S338. If it is confirmed in step S334 that the predetermined time has not elapsed, the process directly proceeds to step S336. In this case, the stored vehicle owner temporary position code is maintained. The purpose of the above processing is to delete the temporary vehicle owner code that is no longer meaningful when the vehicle owner has moved over time to avoid confusion. It is.

In step S338, it is checked whether the flow of FIG. 14 has started as a result of receiving the spot code. If not, the process proceeds to step S340, where it is checked whether the flow of FIG. 14 has started as a result of receiving the vehicle owner GPS position code. If this is not the case, the process proceeds to step S342, and it is checked whether or not the flow of FIG. 14 has started as a result of manual input of both owner positions. Further, if this is not the case, the process proceeds to step S344, and the vehicle owner position obtained by an information source other than step S338, step S340 and step S342 when the flow of FIG. It is checked whether the code is received and stored and it is newer than the information obtained by any of steps S338, S340 and S342.

If there is information corresponding to the condition of step S344, the process proceeds to step S346, the information is overwritten and stored as a vehicle owner temporary position information code in the storage unit 12, and the flow ends. On the other hand, if there is no new memory corresponding to step S344, the flow is immediately terminated. Further, also when it is detected that the information on the vehicle owner position is obtained in any of steps S338, S340, and S342, the process proceeds to step S346, and the information is the vehicle owner temporary position information in the storage unit 12. It is overwritten and stored as a code, and the flow ends.

FIG. 15 relates to the third embodiment and is a flowchart showing the function of the first portable control unit 6 for searching for a vehicle by utilizing the parking code stored in FIG. Note that the flow of FIG. 15 functions in the same manner when the first mobile phone 1 is held by the vehicle owner and when it is held by the substitute driver. In the latter case, the parking code is not stored by itself, but is transmitted from the mobile phone of the vehicle owner to the mobile phone of the substitute driver by the functions of steps S280 and S286 in FIG. In the following description, the function of the first mobile control unit 6 will be described by taking as an example the case where the substitute driver is the holder of the first mobile phone 1. This is because the substitute driver does not know the parking place of the vehicle because he / she did not park the vehicle by himself / herself, so that he / she can enjoy more functions of FIG. 15 and this function is an important element for the substitute driving business. Because. However, even when the vehicle owner himself parks, for example, he may forget where he parked in a large parking lot, and the function of FIG. 15 is useful for the vehicle owner himself.

The flow in FIG. 15 starts when an operation is manually operated to search for a vehicle, and an interrupt is applied. However, even when the vehicle approaches a parking lot and enters the near field communication range, the interrupt is automatically generated. And start. When the flow starts, it is checked in step S352 whether a parking code is stored. In the case of the substitute driver, the parking code is received together with the temporary entry code, and it is checked whether or not it is stored in the storage unit 12. If there is storage, the process proceeds to step S354, a display with storage is performed, and the process proceeds to step S356. In step S356, it is checked whether the parking code includes the garage code. If it is not detected that the garage code is included, the process proceeds to step S358, and it is checked whether the vehicle GPS position code is included in the parking code.

If it is detected in step S358 that the vehicle GPS position code is included, the process proceeds to step S360. On the other hand, when it is detected in step S356 that the garage code is included in the parking code, the process proceeds to step S362, where the garage code is converted into a GPS position code that can be displayed on the GPS map, and the process proceeds to step S360. move on. In step S360, it is checked whether or not the GPS information of the owner of the first mobile phone 1 searching for the vehicle (the substitute driver in this description) is acquired by the GPS unit 16 of the first mobile phone 1. If acquired, the process proceeds to step S364, and both the target vehicle position or garage position and the substitute driver who is the starting point are displayed on the GPS map. This makes it possible to determine the positional relationship and route between the starting point and the parking lot. In this case, not only the starting point and the parking lot position that is the target point may be displayed, but the route between the two may be calculated and displayed.

When the map display is performed in step S364, the process proceeds to step S366 while continuing this display. On the other hand, when the GPS position code of the substitute driver cannot be acquired because the user is not in the communication range in step S360, the process proceeds to step S368, where only the vehicle position is displayed on the GPS map and the parking position is displayed on the map. It is possible to confirm with. Also in this case, the process proceeds to step S366 while the map display is continued.

In step S366, it is checked whether or not the first mobile phone 1 has entered the communication range of the short-range communication unit of the garage and the information has been received by the first mobile short-range communication unit. And if it is in the zone, it will progress to Step S370 and will receive the data of the map system in the garage from the garage. And it progresses to step S372 and it is checked whether the relative position code in a garage is contained in the parking code. When the relative position code is not detected in step S372, the process proceeds to step S374, and it is checked whether the parking code includes the garage position code. If it is included, the process proceeds to step S376, where the vehicle position is displayed on the garage map based on the system data and the garage position code received in step S370, and an instruction to continue the display is issued to end the flow. This display can be terminated by operating the telephone operation unit after use.

On the other hand, when the relative position code is detected in step S372, the process proceeds to step S380, and the relative position code is converted into a garage position code that can be handled on the map based on the system data received in step S370. In step S376, the vehicle position is displayed. If the storage of the parking code cannot be detected in step S352, the process proceeds to step S382, a display without storage is performed, and the flow ends.

FIG. 16 relates to the third embodiment and is a flowchart showing functions of the first portable control unit 6 relating to utilization of the vehicle owner position code. This vehicle owner position code is stored in FIG. 14, and is approved in step S266 of FIG. 12 and then transmitted to the driving agent in step S286. Therefore, the function of the flow of FIG. 16 is used in principle when the first mobile phone 1 is held by the substitute driver. The flow in FIG. 16 is started when the substitute driver manually operates the telephone operation unit 8 to confirm the position of the vehicle owner. In addition, when the substitute driver approaches the vehicle 3 and enters the communication range of the vehicle short-range communication unit 48, an automatic interruption is automatically started.

When the flow of FIG. 16 starts, it is checked in step S392 whether a vehicle owner position code has arrived. If there is an incoming call, the process proceeds to step S394, where an incoming call is displayed, and the process proceeds to step S396. In step S396, the incoming vehicle owner position code is transmitted to the vehicle car navigation system as the destination. This transmission is performed from the first telephone communication unit 18 or the first portable short-range communication unit 20 if possible. Next, in step S398, it is checked whether or not a vehicle position code indicating the middle tea position has arrived. If it has been received, in step S400, the vehicle position code is transmitted to the car navigation system as a starting point.

Next, in step S402, a route search start signal is transmitted to the vehicle car navigation system. Thus, according to the present invention, a route search for car navigation can be performed based on starting point information and destination information that the vehicle itself did not obtain by GPS. When the route search instruction ends, the flow proceeds to step S404, and it is checked whether an operation for transmitting a signal for releasing the engine lock is performed based on the temporary entry code. When it is detected that the engine unlocking new party transmission operation has been performed, the process proceeds to step S406, a car navigation start signal is transmitted to the vehicle, and the flow is terminated. On the other hand, if it is not detected in step S404 that the engine unlock signal transmission operation has been performed, the flow is immediately terminated. In this case, the engine unlock signal is transmitted based on another operation.

If the vehicle position code has not arrived in step S398, the process proceeds to step S408 to check whether the vehicle is parked within the GPS range. If it is within the GPS range, the vehicle position code as the starting point is directly obtained, so the process proceeds to step S402, and a route search start signal is transmitted to the vehicle car navigation system. On the other hand, if it is not detected in step S408 that the vehicle is parked in the GPS range, the process proceeds to step S404, and a check is made as to whether an engine unlock signal transmission operation has been performed. In this case, since there is no car navigation starting point information, the route cannot be searched immediately. However, since the destination information is input to the car navigation system in step S396, if the vehicle leaves the garage, Since a position code is obtained, a route search is possible. If the vehicle owner position code has not arrived in step S392, the flow proceeds to step S410 to display no incoming call, and the flow is immediately terminated. In this case, the vehicle owner is contacted by another means, and information on the route to be picked up is obtained by proxy operation.

In FIG. 1, the vehicle control unit 38, the vehicle operation unit 40, the storage unit 44, the GPS unit 46, and a display unit (not shown) can function as a car navigation device in cooperation. When such a car navigation apparatus receives information transmitted in steps S396 and S400 in FIG. 16, the received information is set as destination information of the vehicle and current position information of the vehicle, respectively. Then, the car navigation device instructed to start the route search in step S402 calculates the travel route of the vehicle from the vehicle current location information and the vehicle destination information set by reception.
