Abstract

PROBLEM TO BE SOLVED: To provide a vehicle control system capable of further improving security.SOLUTION: When receiving a permission signal from a portable terminal 4, an ECU 35 allows a determination part 35b to determine whether or not the permission signal is correct. If the permission signal is determined to be correct, the ECU 35 permits output of a signal to a transmission control part 73. Thereby, on the basis of a parking lock release request signal through operation of a P position switch 72, the transmission control part 73 drives a parking lock actuator 74 to switch a parking lock state. The transmission control part 73 then outputs a parking lock state signal to the ECU 35. On the basis of the parking lock state signal, the ECU 35 recognizes that the parking lock is released. On the basis of a shift position signal, the ECU 35 then controls a shift according to each shift position.

Transmits a permission signal for permitting the vehicle-mounted device to output a transmission control signal through the operation, and the vehicle-mounted device is permitted to output the transmission control signal when receiving the permission signal. It is said.

  According to this configuration, the permission signal is transmitted by operating the mobile terminal. When the in-vehicle device receives the permission signal, the transmission of the transmission control signal is permitted. As a result, even when the electronic key is authenticated, a signal to the transmission control means is not output unless there is a permission signal from the portable terminal, so that the vehicle cannot travel. Therefore, unauthorized use or theft of the car can be suppressed.

The invention according to claim 2 is the vehicle control system according to claim 1,
The gist of the transmission control signal is a shift position signal.

  According to this configuration, the in-vehicle device is permitted to output the shift position signal only when receiving the permission signal from the mobile terminal. Therefore, even if the authentication of the electronic key is established, the shift position signal is not output unless there is a permission signal from the portable terminal, so that the vehicle cannot travel. Therefore, unauthorized use or theft of the car can be suppressed.

The invention according to claim 3 is the vehicle control system according to claim 1 or 2,
The gist of the portable terminal is that it has a timer function that enables the automatic transmission timing of the permission signal to be set.

    According to this configuration, the permission signal can be automatically transmitted using the timer function. According to the convenience of the user (frequency of use of the car), permission or prohibition of automatic transmission of permission signals can be set in a lump for each time zone, for example.

  Invention of Claim 4 is a vehicle control system as described in any one of Claims 1-3. WHEREIN: The said vehicle equipment has a position measurement means to measure an own position, Through the said position measurement means The acquired vehicle position information is transmitted to the mobile terminal, and the mobile terminal stores a position measuring unit that measures its own position, and a storage unit that stores a specified value that serves as a reference when determining a distance from the vehicle. The mobile terminal calculates the distance between the mobile terminal and the vehicle from the terminal position information acquired by its own position measuring means and the vehicle position information from the in-vehicle device, and the distance is the specified value. When it is determined that the following is true, the gist is to transmit or permit transmission of the permission signal.

  According to this configuration, when it is determined that the distance between the mobile terminal and the vehicle is equal to or less than the specified value, automatic transmission or transmission of the permission signal is permitted. When the automatic transmission configuration is adopted, the permission signal is automatically transmitted depending on the positional relationship between the vehicle and the mobile terminal, regardless of the operation of the mobile terminal, which is convenient. When a configuration that permits transmission is adopted, crime prevention is improved.

  According to a fifth aspect of the present invention, in the vehicle control system according to any one of the first to fourth aspects, the portable terminal sends an information control center with a prohibition signal for prohibiting the output of a transmission control signal through its operation. The gist is that transmission to the vehicle via the transmission is possible.

    According to this configuration, the prohibition signal can be transmitted to the vehicle via the information control center. Thereby, the output of the transmission control signal of the vehicle can be prohibited even from a long distance. Thus, unauthorized use of the vehicle can be suppressed through control of the transmission of the vehicle even after a distance from the vehicle or after the vehicle is stolen and moved.

  According to the present invention, the security of the vehicle is further improved.

Hereinafter, an embodiment embodied in the vehicle control system of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the vehicle control system 1 includes an electronic key system 6, a mobile terminal 4, and an information control center 5. The electronic key system 6 includes an electronic key 2 and an in-vehicle device 3 mounted on the vehicle. In the electronic key system 6, control such as door locking / unlocking and engine start permission is performed by wireless communication performed between the electronic key 2 and the vehicle-mounted device 3. The electronic key system 6 includes a key operation free system and a wireless key system. The key operation free system uses the mutual wireless communication between the electronic key 2 and the vehicle-mounted device 3 to perform door locking / unlocking and engine start permission. The wireless key system uses a one-way communication from the electronic key 2 to the in-vehicle device 3 to lock and unlock the door.

<Electronic key>
First, the structure concerning the key operation free system in the electronic key 2 is demonstrated.
As shown in FIG. 1, the electronic key 2 includes a microcomputer 23, an LF reception circuit 24 that receives a radio signal in the LF (low frequency) band, and a UHF transmission circuit that transmits a radio signal in the UHF (Ultra High Frequency) band. 25.

  The LF reception circuit 24 receives a request signal transmitted from the in-vehicle device 3 via the LF reception antenna 27. The request signal is an LF band radio signal. The LF receiving circuit 24 demodulates the received signal into a pulse signal and outputs it to the microcomputer 23.

  The microcomputer 23 includes a nonvolatile memory 23a, and an ID code unique to the electronic key 2 is stored in the memory 23a. When the microcomputer 23 recognizes the request signal from the LF reception circuit 24, the microcomputer 23 outputs a response signal including the ID code stored in the memory 23a to the UHF transmission circuit 25. The UHF transmission circuit 25 modulates the response signal and transmits the response signal as a UHF band radio signal via the UHF transmission antenna 26.

  Next, a configuration related to the wireless key system in the electronic key 2 will be described. In the wireless key system, the microcomputer 23 and the UHF transmission circuit 25 are shared with the key operation free system. The electronic key 2 includes an unlock switch 21 and a lock switch 22. The unlock switch 21 and the lock switch 22 are arranged on the surface of the electronic key 2 so as to be operable. When operated, the unlock switch 21 and the lock switch 22 output an operation signal indicating that to the microcomputer 23.

  When the microcomputer 23 receives an operation signal indicating that the unlock switch 21 has been operated, the microcomputer 23 generates an unlock request signal including an instruction to request unlocking of the vehicle door and an ID code, and outputs the unlock request signal to the UHF transmission circuit 25. Is transmitted as a UHF band radio signal. Even when the microcomputer 23 receives an operation signal indicating that the lock switch 22 has been operated, the UHF transmission circuit 25 sends a locking request signal including an instruction to request locking of the door and an ID code in the same manner as described above. Via wireless transmission.

<In-vehicle device>
Next, the structure which concerns on the key operation free system in the vehicle equipment 3 is demonstrated.
As shown in FIG. 1, the in-vehicle device 3 includes an ECU 35 having an ID code verification function of the electronic key 2, an LF transmission circuit 32 that transmits an LF band radio signal outside the vehicle, a UHF reception antenna 33, and the electronic key 2. A UHF receiving circuit 34 for receiving a UHF band radio signal transmitted from the, and an ignition switch (hereinafter abbreviated as IGSW) 36. The LF transmission circuit 32, the UHF reception circuit 34, and the IGSW 36 are each connected to the ECU 35. The LF transmission circuit 32 has an LF transmission antenna 31, and the UHF reception circuit 34 has a UHF reception antenna 33.

  The ECU 35 includes a non-working memory 35a and a determination unit 35b. The determination unit 35b determines whether a later-described permission signal that allows the ECU 35 to output a signal from the ECU 35 to the transmission control unit 73 is correct. Further, although not shown, the memory 35a stores the same ID code and specified value as those of the electronic key 2. The specified value is a reference for determining the position of the electronic key 2 to be described later with respect to the vehicle-mounted device 3 (vehicle), more precisely, the distance between the electronic key 2 and the vehicle-mounted device 3.

When a request signal is input from the ECU 35, the LF transmission circuit 32 modulates the request signal and transmits the modulated signal as an LF band radio signal via the LF transmission antenna 31.
When the UHF receiving circuit 34 receives the response signal transmitted from the electronic key 2 via the UHF receiving antenna 33, the UHF receiving circuit 34 demodulates the response signal and outputs it to the ECU 35. The ECU 35 collates the ID code included in the response signal received through the UHF receiving circuit 34 with the ID code stored in the memory 35a (key operation free collation). When it is determined that the key operation free verification is established, the ECU 35 executes control such as locking or unlocking of the door through the door lock device (vehicle device) or permission of starting the engine.

  Next, a configuration related to the wireless key system in the in-vehicle device 3 will be described. In the wireless key system, the UHF receiving circuit 34 is shared with the key operation free system.

  The UHF receiving circuit 34 demodulates the unlock request signal or the lock request signal received through its own UHF receiving antenna 33 and outputs it to the ECU 35. When the ECU 35 recognizes the unlock request signal from the UHF receiving circuit 34, the ECU 35 compares the ID code included in the unlock request signal with the ID code stored in the memory 35a (wireless verification). The ECU 35 unlocks the vehicle door when determining that the wireless verification is established. The ECU 35 locks the vehicle door when determining that the wireless verification for the ID code included in the locking request signal has been established. On the other hand, the ECU 35 does not switch the locking / unlocking state of the vehicle door when it is determined that the wireless verification is not established.

As shown in FIG. 1, the in-vehicle device 3 includes a communication unit 52 and a communication antenna 51. The communication unit 52 enables wireless communication between the mobile terminal 4 and the in-vehicle device 3. As the communication method, for example, “BT” and “3G” are adopted. Here, “BT” is an abbreviation of “Bluetooth (registered trademark)” and is a wireless communication standard using a 2.4 GHz band for portable information devices. The "3G", is an abbreviation of the generic name of the mobile phone system of the third generation (3 ^rd Generation). The communication unit 52 corresponds to the receiving unit described in the claims.

  The communication antenna 51 is connected to the ECU 35 via the communication unit 52. The communication unit 52 receives the permission signal transmitted wirelessly from the portable terminal 4 via the communication antenna 51 and outputs the received permission signal to the ECU 35.

When the ECU 35 recognizes the permission signal, the determination unit 35b determines whether the permission signal is correct. The ECU 35 permits the output of a signal from the ECU 35 to the transmission control unit 73 when the determination unit 35b determines that the permission signal is correct. On the other hand, when the determination unit 35b determines that the permission signal is not correct, the ECU 35 prohibits output of a signal from the ECU 35 to the transmission control unit 73.
<Shiftmatic system configuration>
The vehicle control system 1 has a shiftmatic system. In the shiftmatic system, the ECU 35 is shared with the electronic key system 6.

  As shown in FIG. 1, the shiftmatic system includes a shift lever position sensor 71, a P position switch 72, a transmission control unit 73, and a parking lock actuator 74.

  Shift lever position sensor 71 and P position switch 72 are each connected to ECU 35. The parking lock actuator 74 is connected to the ECU 35 via the transmission control unit 73. The shift lever position sensor 71 detects the operation position (R, N, D, B) of the shift lever, and generates a position signal corresponding to each operation position. The P position switch 72 is operated when locking the parking lock state from unlocking.

The ECU 35 outputs a parking lock unlock signal to the transmission controller 73 when the following two conditions (A) and (B) are satisfied.
(A) After the ID verification of the electronic key 2 is established, a signal indicating that the IGSW 36 is turned on by a user operation is received.

(B) The permission signal from the mobile terminal 4 has been received.
The transmission control unit 73 drives the parking lock actuator 74 based on the parking lock unlock signal, and switches the parking lock mechanism (not shown) from the unlocked state to the locked state. At this time, the transmission control unit 73 transmits to the ECU 35 a parking lock state signal that indicates the state of the parking lock mechanism, that is, whether the parking lock mechanism is locked or unlocked. The ECU 35 recognizes the state of the parking lock mechanism based on the parking lock state signal from the transmission control unit 73. When it is recognized that the parking lock mechanism is unlocked, the ECU 35 performs shift control according to each shift position based on the shift position signal from the shift lever position sensor 71. This makes it possible to drive the vehicle.

<Configuration of mobile terminal>
Next, the configuration of the mobile terminal 4 will be described. The mobile terminal 4 is obtained by installing a dedicated application on a mobile terminal (mobile phone) that is generally commercially available. As shown in FIG. 1, the mobile terminal 4 includes a GPS antenna 48, a GPS communication circuit 41, a 3G communication circuit 45, a 3G antenna 44, a non-working memory 43, a control unit 42, and a BT antenna 46. The BT communication circuit 47 is provided. “GPS” is an abbreviation for “Global Positioning System”.

  The 3G antenna 44 is connected to the control unit 42 via the 3G communication circuit 45. The GPS antenna 48 is connected to the control unit 42 via the GPS communication circuit 41. The BT antenna 46 is connected to the control unit 42 via the BT communication circuit 47. The memory 43 stores an application 43a and a permission signal (not shown). The memory 43 is connected to the control unit 42.

In the application, the output control function of the permission signal, the timer function, and the position measurement function can be freely set by operating the portable terminal 4.
The permission signal output control function is a function for controlling whether or not to output a permission signal through the presence or absence of a user's operation. The output control function of the permission signal will be described representatively. For example, when “transmission of permission signal (output)” is selected on the operation screen of the application displayed on the display (not shown) of the portable terminal 4, the permission signal stored in the memory 43 is transmitted to the in-vehicle device 3. .

The timer function is a function that collectively sets whether to output a permission signal for each time zone.
The position measurement function is a function that allows the mobile terminal 4 and the vehicle to set whether to output a permission signal based on the acquired position information. These timer function and position measurement function can also be set through an operation on the operation screen of the application, as in the case where the permission signal is manually transmitted.

<Information Control Center>
The information control center 5 mediates exchange of information between the electronic key 2 and the in-vehicle device 3. The permission signal transmitted from the portable terminal 4 is transmitted to the vehicle via the information control center 5.

<Operation of vehicle control system>
Next, the operation of the vehicle control system (application operation), particularly the permission signal processing of the in-vehicle device 3 will be mainly described. This process is executed by the ECU 35 after the ID code verification of the electronic key system 6 is established. In addition, the parking lock mechanism is in a locked state when the ID code verification is established.

As shown in the flowchart of FIG. 2, first, in step S110, the ECU 35 receives a signal indicating that the IGSW 36 is turned on by a user operation.
Next, the ECU 35 proceeds to the operation in step S120 and determines whether or not the permission signal from the portable terminal 4 is received by the determination unit 35b. If ECU35 determines with not receiving the permission signal from the portable terminal 4 (S120: NO), the said process will be complete | finished. That is, since the ECU 35 does not output a signal to the transmission control unit 73, specifically, a parking unlock signal, the parking lock state is maintained. On the other hand, if it determines with having received the permission signal from the portable terminal 4 (S120: YES), ECU35 will transfer a process to step S130 and will permit the output of the signal to the transmission control part 73 from self. At this time, if the ID code verification is established, the ECU 35 outputs a parking unlock signal to the transmission control unit 73.

  Next, the ECU 35 proceeds to step S140 to recognize the parking lock state signal from the transmission control unit 73 and the shift position signal from the shift lever position sensor 71.

  Finally, the ECU 35 moves the process to step S150. In step S150, the ECU 35 recognizes that the parking lock has been released based on the parking lock state signal. The ECU 35 controls the transmission based on the shift position signal. Thereafter, the process ends.

  Each time the vehicle is used, output control of the permission signal is performed by operating the mobile terminal 4. In the vehicle control system of this example, the following permission signal output control is also possible. That is, output control of the permission signal by the timer function and the position measurement function described above.

<Timer function>
First, the timer function of the application will be described.
When the timer function of the application is turned on, priority is given to processing in the time zone set by the timer function. For example, if it is set to prohibit the output of the permission signal in the night time zone and to permit the output of the permission signal in the day time zone, the automatic operation is automatically performed even if there is no operation of the portable terminal 4 in the time zone in which the permission is set. A permission signal is transmitted to Note that the permission signal may be transmitted periodically or continuously in the time zone for which permission is set.

<Position measurement function>
Next, the position measurement function of the application will be described.
When the position measurement function of the application is turned on, position measurement is performed using the GPS of the car navigation system installed in the car and the GPS function of the portable terminal 4, and the transmission of the permission signal is automatically performed based on the position information. Do. Specifically, the ECU 35 transmits position information measured by the GPS of the mounted car navigation to the mobile terminal 4 via the communication unit 52. The portable terminal 4 calculates the distance between the portable terminal 4 and the car from the position information received from the in-vehicle device 3 and the position information measured by its own GPS, and stores the distance in the memory 43 when the distance is equal to or less than the specified value. The permission signal is automatically transmitted. On the other hand, when the calculated distance exceeds the specified value, the portable terminal 4 does not permit transmission of the permission signal. In addition, GPS of the vehicle equipment 3 and the portable terminal 4 is equivalent to a position measurement means, and the memory 43 is equivalent to a memory | storage means.

As described above, according to the embodiment described above, the following effects can be obtained.
(1) As long as there is no permission signal from the portable terminal 4, the output of the signal from the ECU 35 to the transmission control unit 73 is prohibited. Thereby, since the parking lock is not released only by the ID verification, the vehicle cannot be driven. Therefore, since unauthorized use of the vehicle is suppressed, a high antitheft property can be obtained.

  (2) Whether or not the permission signal is automatically transmitted from the portable terminal 4 can be set at a time for each time zone depending on the application. Thereby, it is possible to set whether or not to automatically transmit a permission signal in a time zone that is permitted and set in accordance with the convenience of the user, so that the convenience of operation can be improved. Incidentally, instead of automatically transmitting the permission signal, the transmission of the permission signal may be performed through the operation of the portable terminal 4 while only permitting the transmission of the permission signal.

  (3) The application can set whether or not the portable terminal 4 and the vehicle automatically transmit the permission signal based on the acquired position information. The portable terminal 4 calculates the distance between the portable terminal 4 and the vehicle from its own position information and the vehicle position information, and automatically transmits a permission signal when the distance is equal to or less than a specified value. Convenience can be improved. Incidentally, instead of automatically transmitting the permission signal, the transmission of the permission signal may be performed through the operation of the portable terminal 4 while only permitting the transmission of the permission signal.

<Other embodiments>
In addition, the said embodiment can be implemented with the following forms which changed this suitably.
In the present embodiment, the electronic key system 6 shown in FIG. 1 includes a key operation free system and a wireless key system, but may include only a wireless key system. In the wireless key system, a door locking / unlocking operation is executed by unidirectional communication between the electronic key 2 and the vehicle-mounted device 3. For this reason, the LF receiving antenna 27 and the LF receiving circuit 24 of the electronic key 2 are omitted. Further, the LF transmission antenna 31, the LF transmission circuit 32, and the IGSW 36 of the in-vehicle device 3 are also omitted.

  Unlike the electronic key system 6, the wireless key system performs a door locking / unlocking operation by operating the unlock switch 21 and the lock switch 22 of the electronic key 2. The processing of the permission signal in the in-vehicle device 3 is the same as that of the electronic key system 6. However, in the case of the wireless key system, since there is no IGSW 36, the IGSW 36 is turned on by inserting the key plate of the electronic key 2 into the key cylinder and turning it clockwise. Then, the IGSW 36 transmits a signal indicating that it is turned on to the ECU 35. As a result, even in the wireless key system, the effects (1) to (4) of the present embodiment can be obtained.

  The present embodiment may include only a key operation free system. In this case, the unlock switch 21 and the lock switch 22 of the electronic key 2 are omitted. Similar to the electronic key system 6 shown in FIG. 1, control such as door locking / unlocking or engine start permission is executed by mutual communication between the electronic key 2 and the vehicle-mounted device 3. The processing of the permission signal in the in-vehicle device 3 is the same as that of the electronic key system 6. Accordingly, the effects (1) to (3) of the present embodiment can be obtained even in the key operation free system.

  The mobile terminal 4 may transmit a password or the like instead of the permission signal. Specifically, a dedicated password is set in the application, and this password is wirelessly transmitted to the car. When the ECU 35 determines that the password transmitted from the mobile terminal 4 matches the password registered in the memory 35a in advance, the ECU 35 permits the output of a signal from the ECU 35 to the transmission control unit 73 as in the present embodiment. . As a result, a car can be used even if a different portable terminal 4 inputs a proper password.

  The permission signal may control not only the output of a signal (parking unlock signal) from the ECU 35 to the transmission control unit 73 but also the output of other signals such as a shift position signal from the ECU 35 to the transmission. When controlling the output of the shift position signal, output control of all position signals or individual position signals can be selected by the application. Even if it does in this way, the effect similar to (1)-(3) of this embodiment is acquired.

  The application time zone may be set so that shift position change (output of a shift position signal from the ECU 35 to the transmission) is prohibited in the night time zone, and shift position change is allowed in the day time zone. Since the permission or prohibition of the shift position change can be set in a lump according to the time zone, the convenience of operation of the mobile terminal 4 can be improved.

  In this example, the parking lock is released when the ID collation is established, but the following may be performed. That is, the permission signal to the transmission control unit 73 may include a parking unlock signal. Accordingly, a signal is output to the transmission control unit 73 and the parking lock mechanism is automatically released, so that the convenience of operation can be improved.

  -Although the short distance communication of the portable terminal 4 uses BT communication, you may use another radio | wireless communication means. For example, a communication method such as infrared communication or 3G communication of the mobile terminal 4 may be used. Even in this case, the permission signal can be transmitted directly to the in-vehicle device 3. Therefore, the same effects as (1) to (3) of this embodiment can be obtained.

Next, the technical idea that can be grasped from the embodiment will be described together with the effects.
(A) The vehicle control system according to any one of claims 1 to 5, wherein the transmission control signal includes a parking lock release signal.

  According to this configuration, when the in-vehicle device receives the permission signal, the output of the parking lock release signal is permitted. For this reason, the parking lock can be released simply by operating the shift lever to the position (R, N, D, B) without the P position switch operation.

  (B) In the vehicle control system according to any one of claims 1 to 5, the portable terminal allows a user to permit and disallow a shift position signal and a parking lock release signal as the transmission control signal. Selectable vehicle control system.

  According to this configuration, the vehicle control system can be applied regardless of the vehicle type because the signal to the permitted transmission can be freely selected.
