A vehicle control system having an immobilizer function that makes it possible to start an engine of a vehicle only by a specific portable device has become widespread. In such a vehicle control system, for example, an authentication process based on the authentication information stored in the portable device and the authentication information stored in the vehicle is performed, and the engine can be started for the vehicle only when the authentication is successful. Has been.
Some of the vehicle control systems described above are capable of additionally registering information for authentication of a new portable device in a vehicle in order to cope with a case where a plurality of people use one vehicle (for example, patents). Reference 1). In this case, the engine can be started also by the portable device corresponding to the authentication information additionally registered in the vehicle.

In general, as a method for additionally registering authentication information on a new portable device in a vehicle, a method using a dedicated device called a registration device is known. In this case, the registration machine is connected to the vehicle via an OBD (On-Board Diagnostics) cable, and an instruction for additionally registering the authentication information of the new portable device to the vehicle is issued from the registration machine to the vehicle. The mobile device authentication information can be additionally registered in the vehicle.
However, it is now possible to obtain non-genuine registered machines, and theft of vehicles that misuse these registered machines has occurred.

  Therefore, in view of the above situation, an object of the present invention is to prevent authentication information from being registered by a third party other than the owner of the vehicle and to improve security against vehicle theft.

Is.

  Thus, authentication information cannot be registered unless an operation pattern that cannot be known by the owner of the vehicle is input to the vehicle.

  Second, in the vehicle control system according to the present invention described above, does the control unit perform authentication using the operation pattern in the registration process before receiving an input of the operation pattern in the operation pattern setting process? It is desirable to execute a selection process for selecting whether or not based on an operation.

  Thus, whether to use authentication using the operation pattern is selected based on the intention of the owner of the vehicle.

  Thirdly, in the vehicle control system according to the present invention described above, the control unit can execute an operation pattern change process for changing the storage operation pattern. In the operation pattern change process, the control unit is It is preferable that the storage operation pattern is changed on condition that the operation pattern input using and the storage operation pattern coincide with each other.

  EMBODIMENT OF THE INVENTION Below, the form (henceforth "embodiment") for implementing this invention vehicle control system is demonstrated with reference to an accompanying drawing.

<1. Configuration of vehicle control system>
FIG. 1 is a block diagram showing a configuration of a vehicle control system 0 as an embodiment. FIG. 1 shows only the configuration of the main part according to the present invention extracted from the configuration of the vehicle control system 0.
The vehicle control system 0 includes a vehicle 1 and a portable device (master key 100, sub key 101) that can wirelessly communicate with each other.
The vehicle 1 includes a control unit 2 for performing various controls, a communication unit 3 having a transmission / reception function for performing wireless communication with the master key 100 and the sub key 101, a storage unit 4, a sensor / operator 5 and the like. It has at least an OBD (On-Board Diagnostics) connection portion 6, an engine-related actuator 7, and a door lock actuator 8.

Here, the master key 100 and the sub key 101 as a portable device will be described.
The master key 100 and the sub key 101 are devices that are carried by the driver or the like as keys for starting the engine of the vehicle 1 and locking / unlocking the door.
The master key 100 includes a communication unit 100A that performs wireless communication with the communication unit 3 of the vehicle 1, and an IC (Integrated Circuit) chip 100B that is connected to the communication unit 100A. Although not shown, the master key 100 is provided with a button for performing remote operation of locking and unlocking the door of the vehicle and an indicator (not shown) that emits light in response to the operation of the button.
In the IC chip 100B, master key authentication information 100C, which is identification information unique to the master key 100, is stored. The IC chip 100B performs control for transmitting an operation signal corresponding to the above-described button operation to the vehicle control system 0 side via the communication unit 100A. The IC chip 100B also performs control to transmit the master key authentication information 100C to the vehicle 1 side via the communication unit 100A.

  The sub key 101 includes a communication unit 101A and an IC chip 101B. Since the configuration of the sub key 101 is the same as that of the master key 100 except that the sub key authentication information 101C as identification information unique to the sub key 101 is stored in the IC chip 101B, the duplicate description is avoided.

  In addition, when transmitting the master key authentication information 100C stored in the master key 100 and the subkey authentication information 101C stored in the subkey 101 to the vehicle 1 side, an encryption process may be performed from the viewpoint of security. That is, the IC chip 100B in the master key 100 and the IC chip 101B in the sub key 101 encrypt the master key authentication information 100C and the sub key authentication information 101C, respectively, and transmit them to the vehicle 1 side.

  FIG. 1 also shows a registration device 200 as a device used when registering authentication information on the vehicle 1 side. The registration device 200 includes a computer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In addition, a display 200a as a display unit and an operator 200b for an operator to input an operation are provided. The registration device 200 can communicate with the control unit 2 by being connected to the OBD connection unit 6 of the vehicle 1 via the OBD cable 201.

  In the vehicle 1, the communication unit 3 performs wireless communication with the communication unit 100 </ b> A of the master key 100 and the communication unit 101 </ b> A of the sub key 101.

The storage unit 4 is configured by a nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory), for example, and stores various data necessary for controlling the vehicle 1. In particular, the storage unit 4 stores vehicle-side authentication information used for realizing the immobilizer function. In the state at the time of delivery shown in FIG. 1, the storage unit 4 stores vehicle-side master key authentication information 4A as vehicle-side authentication information. In this example, the vehicle-side master key authentication information 4 </ b> A is the same information as the master key authentication information 100 </ b> C stored in the master key 100.
The storage unit 4 stores sub-key authentication information 101C as vehicle-side sub-key authentication information along with a registration process (FIG. 3), which will be described later, and an operation pattern setting process (FIG. 2), which will be described later. Information on operation patterns (stored operation patterns) is also stored, which will be described later.

  The sensors / operators 5 comprehensively represent various sensors used for vehicle control, various drivers for a driver to input operations to the vehicle 1. Examples of the sensor include an accelerator opening sensor 5A that detects the accelerator opening from the depression amount of the accelerator pedal, and a brake switch 5B that is turned on / off in response to operation / non-operation of the brake pedal. Examples of the operation element include a start button 5C for instructing start and stop of the engine, a wiper switch 5D for instructing wiper operation, and the like.

  The OBD connection unit 6 is connected to an OBD cable 201 for connecting an external device such as the registration device 200, and can input / output various types of information to / from the external device connected via the OBD cable 201. It is said that.

  The engine-related actuator 7 comprehensively represents various actuators related to the engine. Examples of the engine-related actuator 7 include a throttle actuator that drives a throttle valve, an injector that performs fuel injection, and a cell motor that is used to start the engine.

  The door lock actuator 8 represents an actuator for locking and unlocking the door, and is an actuator such as a motor for driving a door lock / unlock mechanism.

The control unit 2 is configured by a computer having a CPU, a ROM, a RAM, and the like, and executes various processes for vehicle control. As shown in the figure, the control unit 2 is connected to a communication unit 3, a storage unit 4, sensors / operators 5, an OBD connection unit 6, an engine-related actuator 7, and a door lock actuator 8.
Based on detection signals from predetermined sensors such as an accelerator opening sensor 5A provided as sensors / operators 5 and operation input information by the operators, the control unit 2 is provided with predetermined actuators 7 provided as engine-related actuators 7. The engine is controlled by controlling the actuator.
Further, the control unit 2 is based on operation input information by a predetermined operator provided as a door / lock operation or unlocking operation of the master key 100 or the sub key 101 via the communication unit 3 or the sensor / operator 5. The door lock actuator 8 is controlled to lock / unlock the door.
Furthermore, the control part 2 performs the process for implement | achieving an immobilizer function. That is, an authentication process using the authentication information received from the portable device side as the master key 100 or the sub key 101 and the authentication information stored in the storage unit 4 is performed, and the engine related information is based on the result of the authentication process. Processing for starting the engine by the actuator 7 (engine start control processing) is executed. Specifically, in the engine start control process of this example, as the above-described authentication process, the authentication information received from the portable device side and the authentication information stored in the storage unit 4 are collated and they match. Determine whether or not. If the authentication information matches and the authentication is successful, the engine-related actuator 7 executes the engine start. If the authentication information does not match and the authentication fails, the engine-related actuator 7 does not execute the engine start. Process.
When the authentication information is encrypted and transmitted from the portable device side, the control unit 2 decrypts the encrypted authentication information and uses it for the above authentication process. In any case, as the above-described authentication process executed during the engine start control process, an authentication process based on the authentication information stored on the portable device side and the authentication information stored on the vehicle 1 side is performed. That's fine.

  In addition, the control unit 2 performs registration processing for authentication information. In the case of this example, the registration process is executed as a process of adding new portable device authentication information to the storage unit 4, and the details will be described later.

<2. Operation pattern setting process>
In the vehicle control system 0 of the present embodiment, additional registration of authentication information to the vehicle 1 using the registration device 200 is possible by the above registration process. As a result, the engine can be started by the sub key 101 other than the master key 100 or the like.
However, as described above, recently, it is possible to obtain a non-genuine registered machine 200, and vehicles that misuse them have been stolen. Therefore, further improvement in security is desired.

Therefore, in the vehicle control system 0 according to the present embodiment, in order to prevent new authentication information from being registered by a third party other than the owner of the vehicle 1, permission / inhibition of registration of authentication information is permitted. In determining the permission, not only the authentication based on the master key authentication information 100C and the vehicle-side master key authentication information 4A is performed as before, but also the authentication based on the operation pattern is performed.
The operation pattern referred to here is input to the vehicle 1 using a predetermined operation element such as a start button 5C or a wiper switch 5D provided as the operation elements 5. Specifically, in this example, it is assumed that the operation pattern uses the start button 5C.

Hereinafter, first, an operation pattern setting process, which is a process of setting an operation pattern for the vehicle 1, will be described with reference to the flowchart of FIG.
The registration process (FIG. 3) and the operation pattern change process (FIG. 4), which will be described later, starting with the operation pattern setting process of FIG. 2, are executed by the control unit 2 according to a program stored in the ROM or the like described above, for example. Is.
The registration of the operation pattern is performed using the registration device 200. Therefore, when the operation pattern setting process shown in FIG. 2 is executed, it is assumed that the registration device 200 is already connected to the OBD connection unit 6 via the OBD cable 201. In response to the operator performing an operation input for starting the operation pattern setting process on the registration machine 200 connected to the vehicle 1 in this way, a notification to that effect is given to the vehicle 1 side. In response to the notification, the control unit 2 starts an operation pattern setting process.

  First, the control unit 2 executes a process for accepting a selection as to whether or not to use operation pattern authentication in step S101. Specifically, a screen display for selecting whether to use authentication using an operation pattern is executed on the display 200a of the registration device 200, and a selection operation by an operator or the like is accepted.

In subsequent step S102, the control unit 2 determines whether or not to use the operation pattern authentication. That is, based on the result of the selection operation performed on the registration device 200, it is determined whether or not the operation pattern authentication is used in a registration process described later.
If a negative result indicating that the operation pattern authentication is not used is obtained in step S102, the control unit 2 proceeds to step S107, executes the operation pattern authentication non-use process, and ends the process shown in FIG. Specifically, the operation pattern authentication use flag for managing whether or not to use the operation pattern authentication is set to “0”, and the process shown in FIG. 2 ends. The initial value of the operation pattern non-use flag is “1” indicating “use”.

On the other hand, if an affirmative result is obtained in step S102 that the operation pattern authentication is used, the control unit 2 proceeds to step S103, transitions to the operation pattern input acceptance state, and performs a display prompting input of the operation pattern in step S104. An instruction is issued to the registration device 200.
In response to this, the registration device 200 displays on the display screen 200a a prompt to input an operation pattern.

In the next step S105, the control unit 2 stands by until an operation pattern is input. When an operation pattern is input, the control unit 2 performs processing for setting the operation pattern input in step S106 as a storage operation pattern. That is, the input operation pattern is stored in the storage unit 4 as a storage operation pattern. In step S106, a process for instructing the registration device 200 to display that the setting of the operation pattern has been completed may be performed.
The control unit 2 finishes the operation pattern setting process shown in FIG. 2 in response to the execution of the setting process in step S106.

  In the above example, the operation pattern setting is completed by inputting the operation pattern once. However, in order to prevent an input error, the operator is prompted to input the second operation pattern, and the first and second times are input. These input operation patterns may coincide with each other as a setting condition for the storage operation pattern.

<3. Registration process>
Next, the authentication information registration process will be described with reference to the flowchart of FIG. Hereinafter, as an example of registration of authentication information, an example in which the subkey authentication information 101C stored in the subkey 101 is additionally registered in the storage unit 4 will be described.

  Registration of authentication information is also performed using the registration device 200. When the registration process shown in FIG. 3 is executed, the registration device 200 is already connected to the OBD connection unit 6 via the OBD cable 201. Suppose that In response to an operation input for the registration machine 200 to start registration processing, a notification to that effect is given to the vehicle 1, and the control unit 2 starts registration processing in response to the notification. To do.

  The control unit 2 first determines whether or not the master key 100 is detected in step S201. That is, it is determined whether or not communication with the master key 100 is possible. If the master key 100 is not detected, the authentication process in the following step S202 cannot be performed, and therefore the control unit 2 proceeds to step S212 to execute the registration NG process, and then ends the process shown in FIG. As the registration NG process in step S212, for example, a process for causing the registration device 200 to display that the registration process is NG is performed.

On the other hand, if the master key 100 is detected, the control unit 2 performs the authentication process based on the master key authentication information 100C and the vehicle-side master key authentication information 4A in step S202, and whether the authentication is successful in step S203. Determine whether or not. That is, the master key authentication information 100C received by the communication unit 3 and the vehicle-side master key authentication information 4A stored in the storage unit 4 are collated to determine whether or not they match.
When the master key authentication information 100C and the vehicle-side master key authentication information 4A do not match and the authentication is not successful, the control unit 2 executes the registration NG process of step S208 described above and ends the process shown in FIG.

On the other hand, when the master key authentication information 100C matches the vehicle-side master key authentication information 4A and the authentication is successful, the control unit 2 proceeds to step S204 and determines whether or not to use the operation pattern authentication. That is, it is determined whether or not the operation pattern authentication use flag described above is “1”.
If an affirmative result is obtained in step S204 that the operation pattern authentication is used, the control unit 2 proceeds to step S205, transitions to the operation pattern input acceptance state, and performs a display prompting input of the operation pattern in step S206. After instructing the registration device 200, the process waits until an operation pattern is input in step S207.

When an operation pattern is input, the control unit 2 performs an operation pattern authentication process in step S208, and determines in step S209 whether the authentication is successful. That is, the input operation pattern is compared with the operation pattern registered in the storage unit 4 to determine whether or not they match.
If a negative result is obtained that the operation pattern authentication is not successful, the control unit 2 executes the registration NG process in step S212 and ends the process shown in FIG.

On the other hand, when an affirmative result indicating that the operation pattern authentication is successful is obtained, the control unit 2 performs a process of notifying the registration device 200 that the authentication has been successful as the authentication success notification process in step S210.
In response to this notification, the registration device 200 displays on the display 200a a screen indicating that the authentication has been successful, such as a message “authentication has been successful.”

In subsequent step S211, the control unit 2 performs an additional registration process of subkeys. That is, the subkey authentication information 101C transmitted from the communicable subkey 101 and received by the communication unit 3 is stored in the storage unit 4 as vehicle side subkey authentication information. Thus, the engine can be started using not only the master key 100 but also the sub key 101 thereafter.
The control unit 2 finishes the process shown in FIG. 3 in response to the execution of the additional registration process in step S211.

  If a negative result indicating that the operation pattern authentication is not used is obtained in the previous step S204, the control unit 2 passes the processing of the above steps S205 to S210 and proceeds to step S211 to additionally register the sub key 101. Execute the process. In other words, when the operation pattern setting process shown in FIG. 2 is instructed not to use the operation pattern, only the authentication process based on the master key authentication information 100C is performed in the same manner as before when registering the authentication information. Done.

  In the above, an example in which new authentication information is additionally registered in the storage unit 4 is given as the authentication information registration process. However, the authentication process using the operation pattern has already been stored (registered) in the storage unit 4. It can also be applied to the case where registration is performed by rewriting the authentication information. At this time, whether to newly register new authentication information in the storage unit 4 or rewrite the registered authentication information may be selectable by an operation.

<4. Operation pattern change processing>
FIG. 4 is a flowchart showing the flow of the operation pattern change process.
The operation pattern change process is a process for changing the storage operation pattern. Since the storage operation pattern can be changed, for example, when an unintended operation pattern is set due to an operation error or the like in the operation pattern setting process of FIG.

  The change of the storage operation pattern is also performed using the registration device 200. When the change processing shown in FIG. 4 is executed, the registration device 200 is already connected to the OBD connection unit 6 via the OBD cable 201. Yes. In response to the operator performing an operation input for starting the operation pattern changing process on the registration machine 200 connected to the vehicle 1 in this manner, a notification to that effect is given to the vehicle 1 side. In response to the notification, the control unit 2 starts an operation pattern change process.

  In FIG. 4, the control unit 2 first determines whether or not the storage operation pattern has been set in step S301. If the storage operation pattern has not been set, the control unit 2 executes the storage operation pattern change NG process in step S310 and ends the process shown in FIG. In the storage operation pattern change NG process, for example, a process for causing the registration device 200 to execute a display indicating that the storage operation pattern cannot be changed is performed.

  On the other hand, if the storage operation pattern has been set, the control unit 2 transitions to an operation pattern input acceptance state in step S302, and instructs the registration device 200 to display a prompt for input of the storage operation pattern in step S303. I do.

In subsequent step S304, the control unit 2 stands by until an operation pattern is input. When an operation pattern is input, the control unit 2 determines whether or not the operation patterns match in step S305.
In step S305, when a negative result is obtained that the operation pattern input in step S304 and the storage operation pattern in the storage unit 4 do not match, the control unit 2 performs the storage operation pattern change NG process in step S310. The process shown in FIG.

  On the other hand, when an affirmative result is obtained that the operation pattern input in step S305 matches the storage operation pattern, the control unit 2 proceeds to step S306 and enters the input acceptance state of the operation pattern to be newly registered. In step S307, the registration device 200 is instructed to prompt the operation pattern input.

In subsequent step S308, the control unit 2 stands by until an operation pattern is input, and when an operation pattern is input, a storage operation pattern change process is performed in step S309. That is, a process of changing the operation pattern stored in the storage unit 4 to a newly input operation pattern is performed.
The control unit 2 ends the process illustrated in FIG. 4 in response to the execution of the change process in step S309.

<5. Summary>
As described above, the vehicle control system 0 according to the present embodiment is configured to include the vehicle 1 and the portable device (master key 100, sub key 101) that can wirelessly communicate with each other, and the vehicle 1 is a portable device. Stored portable device side authentication information (master key authentication information 100C, subkey authentication information 101C) and vehicle side authentication information stored in vehicle 1 (vehicle side master key authentication information 4A, vehicle side subkey authentication information) The engine start control process for starting the engine based on the result of the authentication process based on the above and the authentication information so that the authentication information related to the authentication process is stored in both the vehicle 1 and the portable device And a control unit 2 that executes registration processing for registration.
And the control part 2 receives the input of the operation pattern using the operator of the vehicle 1, performs the operation pattern setting process which memorize | stores the input operation pattern as a memory | storage operation pattern in the memory | storage part 4, In a registration process, The authentication process based on the operation pattern input using the operation element and the storage operation pattern and the other authentication process are executed, and when both the authentication processes are successful, the authentication information is registered. .

Accordingly, the authentication information cannot be registered unless an operation pattern that cannot be known by the owner of the vehicle 1 is input to the vehicle 1.
Therefore, it is possible to prevent the authentication information from being registered by a third party other than the owner of the vehicle 1 and improve the security against the vehicle theft.

The authentication information registration process may be performed in the following form in addition to the form in which the authentication information stored on the portable device side is stored on the vehicle 1 side as exemplified above. is there.
That is, the authentication information generated on the vehicle 1 side is stored in a portable device (sub key 101 in this example) that is a registration target, or the authentication information is generated on both the vehicle 1 and the portable device that is the registration target. The authentication information generated by the mobile device is stored in the portable device, and the authentication information generated by the mobile device is stored in the vehicle 1.
In any case, the registration process in the present invention is a process for registering authentication information so that authentication information related to the authentication process at the time of engine start is stored in both the vehicle 1 and the portable device. That's fine.

Furthermore, in the above description, an example in which the authentication process based on the operation pattern and the authentication process based on the master key authentication information 100C are performed when determining whether or not the authentication information can be registered is performed. The authentication process is not limited to the authentication process based on the master key authentication information 100C. For example, authentication processing using a PIN code may be performed between the registration device 200 and the vehicle 1. Specifically, an authentication process using the PIN code input via the registration device 200 and the PIN code stored in the storage unit 4 is performed.
At this time, the authentication process performed between the registration device 200 and the vehicle 1 is not limited to the authentication process based on the input PIN code as described above, but may be an authentication process using a predetermined algorithm. Specifically, a predetermined authentication code calculation algorithm is implemented in the authorized registration device 200, and only the authorized registration device 200 can calculate an authentication code corresponding to the authentication information transmitted on the vehicle 1 side. The vehicle 1 side authenticates whether the authentication code calculated by the registration device 200 is a regular authentication code, and reflects the result on whether the authentication information can be registered.
At this time, the registration code 200 does not necessarily have to be calculated by the registration device 200 itself, but may be performed by an external device connected to the registration device 200 so as to be communicable. The connection between the registration device 200 and the external device may be wired or wireless, or may be a connection via a network such as the Internet or a LAN (Local Area Network).

Further, in the vehicle control system 0 of the present embodiment, based on the operation, the control unit 2 determines whether or not to perform authentication using the operation pattern in the registration process before receiving the input of the operation pattern in the operation pattern setting process. The selection process to select is executed.
Thereby, selection of whether to use the authentication using the operation pattern based on the intention of the owner of the vehicle 1 is performed.
Therefore, it becomes the vehicle control system 0 according to the usage mode of the owner of the vehicle 1, and it can be set as a user-friendly system.

Furthermore, in the vehicle control system 0 of the present embodiment, the control unit 2 can execute an operation pattern change process for changing the storage operation pattern. In the operation pattern change process, an input is performed using an operator. The storage operation pattern is changed on condition that the operation pattern matches the storage operation pattern.
Accordingly, the storage operation pattern cannot be changed unless an operation pattern that cannot be known by the owner of the vehicle 1 is input to the vehicle 1.
Therefore, the possibility that the storage operation pattern is changed by a malicious third party is reduced, and the security against theft of the vehicle 1 can be further improved.

<6. Modification>
While the embodiments according to the present invention have been described above, the present invention should not be limited to the specific examples illustrated above.
For example, in the above, when it is selected that the operation pattern authentication is not used in the operation pattern setting process, only the authentication process other than the authentication process based on the operation pattern is performed in the registration process. If it is selected not to use the operation pattern authentication in step S1, the authentication information may not be registered. Thereby, security can be improved.

  In the above description, the operation pattern setting process (FIG. 2), the registration process (FIG. 3), and the change process (FIG. 4) are all performed using the registration device 200. The present invention can be suitably applied to the case where any one is performed without using the registration device 200. What is necessary is just to start about the process which does not use the registration machine 200 according to the predetermined operation input with respect to the vehicle 1, for example.

  Further, in the above description, an example is given in which the authentication information registration is not allowed if the operation pattern authentication process fails even once. However, the number of failed operation pattern authentication processes reaches a predetermined number of times of 2 or more. In this case, registration of authentication information can be disabled.

  Moreover, although the case where the operation pattern is an operation pattern using only one type of operation element has been described above, the operation pattern may be an operation pattern using a plurality of operation elements. Further, the operating elements to be used are not limited to the start button 5C and the wiper switch 5D described above, and various operations such as an operation pattern using a brake pedal (an on / off pattern of the brake switch 5B) and an operation pattern of a door hook are available. Conceivable.
