Description

  The present invention relates to a vehicle security system used for preventing theft of a vehicle.

  2. Description of the Related Art A so-called electronic key system in which a vehicle door is automatically unlocked when a user holding a portable device (electronic key) approaches the vehicle door or touches the door knob is well known. In this electronic key system, for example, a request signal is transmitted to a communication area set around the vehicle door from a transmission device provided on the vehicle door. Further, the user has a portable device that transmits a response signal including an identification code (ID code) based on reception of the request signal. That is, the response signal is transmitted from the portable device when the user who has the portable device enters the communication area. The response signal transmitted from the portable device is received by a receiving device provided in the vehicle and transmitted to a verification control device (verification ECU) that authenticates the portable device. This collation ECU collates the ID code included in the received response signal with the ID code stored in advance in the built-in memory, and if the ID codes match each other, the portable device is authenticated. Judge that When the authentication of the portable device is established, the vehicle door is unlocked.

  On the other hand, it is effective to mount a security system such as that disclosed in Patent Document 1 on a vehicle equipped with such an electronic key system. In the security system described in Patent Document 1, an alarm is issued from a speaker provided in the vehicle when the vehicle door is opened in a situation where authentication of the portable device is not established. Thus, for example, if a third party breaks the window glass of the vehicle and unlocks the vehicle door and then opens it, an alarm is issued from the speaker, so intimidating the third party trying to intrude into the vehicle Will be able to.

JP 2011-105264 A

  In this way, a warning is issued from the speaker when the vehicle door is opened in a situation where the authentication of the portable device has not been established, so that a third party who surely attempts to intrude into the vehicle is intimidated. Will be able to. However, if a third party breaks the window glass of the vehicle door and then enters the vehicle through a broken portion of the window glass without opening the vehicle door, the speaker will not issue an alarm. There is a risk that a person may intrude into the vehicle. In addition, if the vehicle is an open car, a warning sound will not be emitted from the speaker even if the hood to prevent the entry of wind and rain or dust into the vehicle is broken by a third party. There is a risk that a third party may enter the car. In such a case, for example, when a third party tries to move the vehicle, the operation of switching the parking brake from the operating state to the non-operating state, or the operation position of the shift lever is changed from “P (parking) range” to “N (neutral) range”. If an operation for switching to is performed, the vehicle may be moved illegally, which is not preferable in terms of security.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a vehicle security system effective in preventing theft of the vehicle.

  In order to solve the above-mentioned problem, the invention according to claim 1 has a detecting means for detecting a specific operation on the vehicle, and the vehicle is passed through the detecting means during a period when the security function is set to an effective state. In a vehicle security system that issues an alarm through alarm means provided on the vehicle on the condition that a specific operation on the vehicle is detected, the detection means is an operation that cancels the travel restriction of the vehicle as the specific operation. The gist is to detect.

  According to the system, a third party who has illegally entered the vehicle without unlocking the vehicle door attempts to move the vehicle, for example, by switching the parking brake of the vehicle from the activated state to the non-activated state, or by shifting the vehicle. If an operation for canceling the vehicle travel restriction, such as an operation of switching the range from the parking range to the neutral range, is performed, an alarm is issued through alarm means provided in the vehicle. As a result, a third party who has illegally entered the vehicle can be intimidated, so that the vehicle can be prevented from being stolen.

  According to a second aspect of the present invention, in the vehicle security system according to the first aspect, the vehicle is immediately before or immediately after detecting whether or not an operation for canceling the travel restriction of the vehicle has been performed through the detection means. The gist is to authenticate the portable device through wireless communication between the on-vehicle device and the portable device provided, and prohibit the warning by the warning means when the portable device is authenticated.

  According to the system, when an authorized vehicle user performs an operation to cancel the vehicle travel restriction, wireless communication between a portable device possessed by the authorized vehicle user and an in-vehicle device provided in the vehicle is performed. When the portable device is authenticated and the authentication is established, an alarm from the alarm means is prohibited. As a result, it is possible to avoid a situation in which an alarm is erroneously issued from the alarm means when an authorized vehicle user is performing an operation to cancel the vehicle travel restriction, and thus a system that is easy for an authorized vehicle user to handle. Can be realized.

And in this case, as an operation for releasing the travel regulation of the vehicle, as in the invention according to claim 3,
-Switching the parking brake of the vehicle from the activated state to the deactivated state;
Or according to the invention of claim 4,
Switching the operation position of the shift lever of the vehicle from the parking range to another range;

  Hereinafter, an embodiment in which a vehicle security system according to the present invention is applied to an electronic key system of a vehicle will be described with reference to FIGS. First, with reference to FIG. 1, the outline | summary of the electronic key system of the vehicle concerning this embodiment is demonstrated.

  As shown in FIG. 1, this electronic key system is a vehicle door that performs two-way wireless communication (smart communication) between a portable device 1 possessed by a user and an in-vehicle device 2 mounted on the vehicle. Is automatically locked and unlocked. That is, in this electronic key system, when the user who has the portable device 1 touches the door knob 3 to get on the vehicle, a request signal and a response signal are exchanged between the portable device 1 and the vehicle-mounted device 2. Authentication of the portable device 1 is performed. When the smart authentication outside the vehicle of the portable device 1 is established, all the doors of the vehicle are unlocked. On the other hand, when the user gets off the vehicle and pushes the lock switch 4 provided on the door knob 3, smart communication is similarly performed between the portable device 1 and the in-vehicle device 2 to authenticate the portable device 1. Is called. When the smart authentication outside the vehicle of the portable device 1 is established, all the doors of the vehicle are locked.

  In this electronic key system, when the user turns on the lock switch 10 or the unlock switch 11 provided in the portable device 1, a lock request signal or an unlock request signal is transmitted from the portable device 1 to the in-vehicle device 2. . And all the doors of the vehicle are locked or unlocked through such unidirectional wireless communication (wireless communication).

Next, the configuration and operation of the electronic key system of the vehicle will be described in detail with reference to FIG.
The portable device 1 includes a receiving device 12 for receiving a request signal transmitted from the in-vehicle device 2 in the above-described smart communication, and a transmitting device 13 for transmitting various wireless signals to the in-vehicle device 2. Then, the processing of the request signal received via the receiving device 12 and the transmission control of various radio signals from the transmitting device 13 are controlled through a portable device control device (portable device ECU) 14 provided in the portable device 1. To be done. That is, when the portable device ECU 14 receives the request signal via the receiving device 12, the portable device ECU 14 generates a response signal including an identification code (ID code) stored in advance in the built-in nonvolatile memory 14a and transmits the response signal. 13 to transmit. In addition, the output of the locking switch 10 and the unlocking switch 11 is captured in the portable machine ECU 14. When the portable device ECU 14 detects that the switch 10 is turned on based on the output of the lock switch 10, the portable device ECU 14 transmits a lock request signal from the transmission device 13. Further, when it is detected that the switch 11 is turned on based on the output of the unlock switch 11, an unlock request signal is transmitted from the transmission device 13.

  On the other hand, the vehicle-mounted device 2 includes a vehicle exterior transmission device 20 for transmitting a request signal to the vehicle exterior communication area A set around the driver door and the passenger door of the vehicle shown in FIG. An in-vehicle transmission device 21 for transmitting a request signal to the in-vehicle communication area B set in the vehicle shown in FIG. The in-vehicle device 2 also includes a receiving device 22 for receiving various wireless signals transmitted from the portable device 1 and a touch that detects whether the user's hand has touched the door knob 3 through a change in capacitance, for example. A sensor 5 is provided. And the output of this touch sensor 5 and the output of the said lock switch 4 are taken in by the collation control apparatus (collation ECU) 23 provided in the vehicle equipment 2. The verification ECU 23 is a part that controls the transmission of request signals from the in-vehicle transmission device 20 and the in-vehicle transmission device 21 and authenticates the portable device 1 based on various signals received via the reception device 22.

  Specifically, when the verification ECU 23 receives the lock request signal or the unlock request signal transmitted from the portable device 1 via the receiving device 22, the verification code included in the received signal and the built-in nonvolatile memory The identification code stored in 23a is collated. If the mutual identification codes match, it is determined that the wireless authentication of the portable device 1 has been established, and the locking request or the unlocking request is made via the in-vehicle network 6 such as a CAN (Controller Area Network). This is performed for a main body control device (main body ECU) 30 provided in the vehicle. Thereby, the main body ECU 30 drives the door lock mechanism 35 based on the locking request or unlocking request from the verification ECU 23, and locks or unlocks all the doors of the vehicle.

  For example, when all the doors of the vehicle are locked, the verification ECU 23 transmits a request signal to the outside communication area A from the outside transmission device 20 at a predetermined cycle. Thereby, when the user who has the portable device 1 enters the outside communication area A, the request signal transmitted from the outside transmission device 20 is received by the portable device 1, and the response signal is transmitted from the portable device 1. At this time, when the verification ECU 23 receives the response signal transmitted from the portable device 1 via the receiving device 22, the verification ECU 23 compares the identification code included in the response signal with the identification code stored in the memory 23a. When the identification codes match each other, it is determined that smart authentication outside the mobile device 1 has been established, and then whether or not the user's hand has touched the door knob 3 is monitored through the touch sensor 5. Here, when it is detected that the user's hand has touched the door knob 3, a request for unlocking the vehicle door is made to the main body ECU 30 via the in-vehicle network 6. As a result, the main body ECU 30 drives the door lock mechanism 35 based on the unlocking request from the verification ECU 23 to unlock all the doors of the vehicle.

  The verification ECU 23 also transmits a request signal from the vehicle exterior transmission device 20 to the vehicle exterior communication area A even when it is detected that the switch 4 is pushed based on the output of the lock switch 4. Accordingly, the request signal is received by the portable device 1 possessed by the user, and a response signal is transmitted from the portable device 1. Also at this time, when the verification ECU 23 receives the response signal transmitted from the portable device 1 via the receiving device 22, the verification ECU 23 compares the identification code included in the response signal with the identification code stored in the memory 23a. To do. If the identification codes match each other, it is determined that smart authentication outside the portable device 1 has been established, and a lock request for the vehicle door is made to the main body ECU 30 via the in-vehicle network 6. As a result, the main body ECU 30 drives the door lock mechanism 35 based on the locking request from the verification ECU 23 to lock the door of the vehicle.

  On the other hand, the vehicle is provided with a door courtesy switch 31, a parking brake switch 32, and a shift sensor 33 as detection means for detecting a specific operation. The door courtesy switch 31 detects the open / closed state of the door of the vehicle. The parking brake switch 32 detects whether or not the parking brake of the vehicle is in an operating state. In the shift sensor 33, the operation position of the shift lever of the vehicle is any one of “P (parking) range”, “N (neutral) range”, “D (drive) range”, and “R (reverse) range”. Is to detect. The outputs of the switches 31 and 32 and the sensor 33 are taken into the main body ECU 30. When the main body ECU 30 detects an unauthorized entry of a third party into the vehicle based on the outputs of the switches 31 and 32 and the sensor 33, the main body ECU 30 issues a warning from a speaker 34 provided in the vehicle. Security processing that threatens the user. Specifically, the main body ECU 30 locks all the doors of the vehicle based on the locking request from the verification ECU 23, that is, based on the establishment of the smart authentication outside the vehicle of the portable device 1 or the establishment of the wireless authentication. When all doors are locked, the security function is automatically enabled. When it is detected that any of the doors of the vehicle is opened based on the output of the door courtesy switch 31 during the period when the security function is set to the valid state, an alarm is issued from the speaker 34 provided on the vehicle. To emit. The main body ECU 30 also issues an alarm from the speaker 34 when detecting an operation for canceling the vehicle travel restriction during the period when the security function is set to the valid state. Specifically, when an operation of switching the parking brake from the operating state to the non-operating state is detected based on the output of the parking brake switch 32, or the operation position of the shift lever is deviated from the parking range based on the output of the shift sensor 33. When any operation of switching to a range other than is detected, an alarm is issued from the speaker 34. Note that the main body ECU 30 notifies that the ignition switch of the vehicle is turned on from the engine control device (engine ECU) 40 mounted on the vehicle via the in-vehicle network 6 during a period in which the security function is in an effective state. If there is, the alarm from the speaker 34 is stopped and the security function is automatically set to an invalid state.

  Next, with reference to FIG. 3, such a security process executed through the main body ECU 30 will be described in detail. Note that the processing shown in FIG. 3 is executed when the security function is set to the valid state. Also, it is interrupted when the security function is set to an invalid state.

  As shown in FIG. 3, in this process, first, it is determined whether any of the doors of the vehicle has been opened based on the output of the door courtesy switch 31 (step S1). When any door of the vehicle is opened (step S1: YES), an alarm is issued from the speaker 34 (step S2). Note that the process of step S2 is continued until the security function is set to an invalid state. That is, once an alarm is issued from the speaker 34, the state continues until the ignition switch of the vehicle is turned on.

  On the other hand, when all the doors of the vehicle are closed (step S1: NO), whether or not an operation for switching the parking brake from the operating state to the non-operating state is detected based on the output of the parking brake switch 32. Determination is made (step S3). Further, when the parking brake is maintained in the operating state or in the non-operating state (step S3: NO), the operation position of the shift lever is set from the parking range based on the output of the shift sensor 33. It is determined whether or not an operation for switching to another range is detected (step S4). Here, when an operation for switching the parking brake from the operating state to the non-operating state is detected (step S3: YES), or when an operation for switching the operation position of the shift lever from the parking range to another range is detected. (Step S4: YES), in-vehicle smart authentication of the portable device 1 is performed (Step S5).

  In the process of step S5, first, the main body ECU 30 makes an in-vehicle authentication request to the verification ECU 23 via the in-vehicle network 6. When there is an in-vehicle authentication request from the main body ECU 30, the verification ECU 23 transmits a request signal from the in-vehicle transmission device 21 to the in-vehicle communication area B. Thereby, when the portable device 1 is located in the in-vehicle communication area B, a response signal is transmitted from the portable device 1. And the collation ECU23 will collate the identification code contained in the response signal, and the identification code memorize | stored in the memory 23a, if the response signal transmitted from the portable device 1 is received via the receiver 22. If the identification codes match each other, it is determined that the in-vehicle smart authentication of the portable device 1 has been established. In this case, an authentication establishment notification indicating that in-vehicle smart authentication of the portable device 1 has been established is transmitted from the verification ECU 23 to the main body ECU 30 via the in-vehicle network 6. On the other hand, the verification ECU 23, when the identification code included in the response signal does not match the ID code stored in the memory 23a, or when a certain time has passed since the request signal was transmitted to the in-vehicle communication area B. If the response signal cannot be received, it is determined that the in-vehicle smart authentication of the portable device 1 is not established. In this case, an authentication failure notification indicating that the in-vehicle smart authentication of the portable device 1 is not established is transmitted from the verification ECU 23 to the main body ECU 30 via the in-vehicle network 6. Then, the main body ECU 30 determines whether or not the in-vehicle smart authentication of the portable device 1 has been established based on the authentication establishment notification and the authentication failure notification from the verification ECU 23 (step S6).

  Here, when the in-vehicle smart authentication of the portable device 1 is not established (step S6: NO), an alarm is issued from the speaker 34 until the ignition switch of the vehicle is turned on (step S2). On the other hand, when there is no change in the operation position of the shift lever (step S4: NO), or when in-car smart authentication of the portable device 1 is established (step S6: YES), an alarm is not issued from the speaker 34. It is again determined whether any door of the vehicle has been opened (step S1).

Next, the operation of the vehicle electronic key system according to the present embodiment will be described.
For example, when the vehicle is parked, a third party breaks the window glass of the vehicle door, and then enters the vehicle from a broken portion of the window glass without opening the vehicle door. At this time, if a third party performs an operation to switch the parking brake from the operating state to the non-operating state in an attempt to move the vehicle, or an operation to switch the operation position of the shift lever from the parking range to another range, In-car smart authentication of the machine 1 is performed. In this case, since the third party does not have the portable device 1, the in-vehicle smart authentication of the portable device 1 is not established. Therefore, since a warning is issued from the vehicle speaker 34, a third party can be threatened. This can prevent the vehicle from being stolen.

  By the way, in such an electronic key system, the security function is enabled even when a legitimate vehicle user accidentally turns on the lock switch 10 of the portable device 1 while getting on and locks all the doors of the vehicle. It becomes. In such a situation, when an authorized vehicle user performs an operation for switching the parking brake from the operating state to the non-operating state or an operation for switching the operation position of the shift lever from the parking range to another range, an alarm is output from the speaker 34. May cause discomfort to legitimate vehicle users. In this regard, in the electronic key system according to the present embodiment, when an authorized vehicle user operates the parking brake or the shift lever in such a situation, the in-vehicle smart authentication of the portable device 1 located in the in-vehicle communication area B is performed. Thus, if this in-vehicle smart authentication is established, no warning is issued from the speaker 34. As a result, it is possible to avoid a situation in which an alarm is issued to an authorized vehicle user, and thus it is possible to realize a system that is easy to handle for an authorized vehicle user.

As described above, according to the electronic key system for a vehicle according to the present embodiment, the following effects can be obtained.
(1) An alarm is issued from the vehicle speaker 34 when an operation for canceling the vehicle travel restriction is detected during a period in which the security function is in an effective state. As a result, a third party who has illegally entered the vehicle can be intimidated, so that the vehicle can be prevented from being stolen.

  (2) As the operation for canceling the vehicle travel restriction, an operation for switching the parking brake from the operating state to the non-operating state and an operation for switching the operation position of the shift lever from the parking range to another range are adopted. As a result, a third party who has entered the vehicle can accurately capture a situation in which the vehicle tries to move the vehicle illegally, and can issue a warning, so that high security can be ensured.

  (3) When the operation of switching the parking brake from the operating state to the non-operating state and the operation of switching the operation position of the shift lever from the parking range to the other range are detected, the in-car smart of the portable device 1 An alarm from the speaker 34 is prohibited on condition that the authentication is established. As a result, it is possible to avoid a situation in which an alarm is erroneously issued when a legitimate user of the vehicle operates the parking brake or the shift lever, so that it is possible to realize a system that is easy for a legitimate user to handle. become.

  (4) The security function is set to the valid state when all the doors of the vehicle are locked based on the establishment of the smart authentication outside the vehicle of the portable device 1 or the establishment of the wireless authentication. In addition, when the ignition switch of the vehicle is turned on, the security function is set to an invalid state and the alarm from the speaker 34 is stopped. Accordingly, the security function is enabled and disabled and the alarm from the speaker 34 is automatically stopped without direct manual operation by the user, so that convenience is improved.

In addition, the said embodiment can also be implemented with the following forms which changed this suitably.
Some vehicle electronic key systems, for example, perform smart authentication inside the portable device 1 when the brake pedal of the vehicle is depressed, and can start the engine on the condition that the authentication is established . When executing the security processing illustrated in FIG. 3 in the electronic key system of such a vehicle, the portable device 1 is executed based on the depression operation of the brake pedal as the processing of step S5 shown in FIG. It is also possible to use the smart certification in the car.

  In the security processing illustrated in FIG. 3 above, whether or not the processing in steps S3 and S4 for detecting whether or not an operation for canceling the vehicle travel restriction has been performed, and whether or not the in-vehicle smart authentication of the portable device 1 is established. The order of performing steps S5 and S6 may be changed. That is, as shown in FIG. 4, when all the doors of the vehicle are closed (step S1: NO), first, in-vehicle smart authentication of the portable device 1 is performed (step S5). If the in-vehicle smart authentication of the portable device 1 is not established (step S6: NO), whether or not an operation for switching the parking brake from the operating state to the non-operating state has been performed (step S3), and the shift lever It is determined whether or not an operation for switching the operation position from the parking range to another range has been performed (step S4). Here, when an operation for switching the parking brake from the operating state to the non-operating state is performed (step S3: YES), or when an operation for switching the operation position of the shift lever from the parking range to another range is performed. (Step S4: YES), an alarm is issued from the speaker 34 (step S2). Even with such a configuration, it is possible to avoid a situation in which an alarm is erroneously issued when the user of the vehicle operates the parking brake or the shift lever. it can.

  -In the electronic key system of the vehicle, for example, when the door of the vehicle is changed from the open state to the closed state, it is determined that the user has boarded, and the in-vehicle smart authentication of the portable device 1 is performed and the authentication is established. Some engines can be started on the condition. In the case of executing the security process shown in FIG. 4 in the electronic key system of such a vehicle, the in-vehicle smart authentication of the portable device 1 executed based on the opening / closing operation of the door of the vehicle is performed as the process of step S5. It is also possible to divert.

  In the security process illustrated in FIG. 3, either the process of step S3 or the process of step S4 may be omitted. That is, as a condition for issuing an alarm from the speaker 34, an operation of switching the parking brake from the operating state to the non-operating state is performed, and an operation of switching the operation position of the shift lever from the parking range to another range is performed. Only one of these may be used as a condition. Even with such a configuration, it is possible to obtain an effect according to the effects (1) and (2).

  As shown in FIG. 5 corresponding to the previous FIG. 3, when all the doors of the vehicle are closed (step S1: NO), an operation for shifting the parking brake from the operating state to the non-operating state, and shift It may be determined whether or not two operations of switching the lever operation position from the parking range to the other range have been performed (step S7). And when these two operations are performed (step S7: YES), the process after step S5 is performed. If these two operations are not performed (step S7: NO), the process returns to step S1. Even with such a configuration, it is possible to obtain an effect according to the effects (1) and (2).

  In the security process illustrated in FIG. 3 and FIG. 4, the processes in steps S5 and S6 may be omitted. That is, regardless of whether or not the smart authentication in the portable device 1 is established when detecting an operation for deactivating the parking brake or an operation for switching the operation position of the shift lever from the parking range to another range. An alarm may be issued from the speaker 34. In the process illustrated in FIG. 5 as well, the processes in steps S5 and S6 can be omitted in the same manner. With such a configuration, for example, even when a third party who has illegally entered the vehicle possesses the portable device 1, the third party can be threatened by an alarm from the speaker 34. It is effective in preventing theft of the user.

  In the above embodiment, the security function is automatically set to the valid state when all the doors of the vehicle are locked based on the establishment of the smart authentication outside the vehicle of the portable device 1 or the establishment of the wireless authentication, and the ignition of the vehicle The security function is automatically disabled when the switch is turned on. Instead of this, for example, a dedicated switch may be provided in the portable device 1 and the security function may be enabled or disabled based on a manual operation of the dedicated switch.

  In the above embodiment, the alarm from the speaker 34 is automatically stopped when the ignition switch of the vehicle is turned on. Alternatively, for example, a dedicated switch may be provided in the vehicle, and the alarm from the speaker 34 may be stopped based on a manual operation of the dedicated switch.

  In the above embodiment, the operation for releasing the parking brake and the operation for switching the operation position of the shift lever from the parking range to another range are adopted as the operation for releasing the vehicle travel restriction. Instead of these operations or in addition to these operations, for example, an operation for switching the operation position of the shift lever to the neutral range, an operation for illegally releasing the steering lock of the vehicle, or the like may be employed.

  In the above-described embodiment, the speaker 34 provided in the vehicle is used as the alarm unit. However, instead of this, for example, a vehicle horn or a hazard lamp may be used. That is, a third party may be threatened by ringing a horn or blinking a hazard lamp.
