Description

  The present invention relates to a vehicle control device mounted on a vehicle capable of starting a drive source such as an engine by authentication with a portable device such as an electronic key.

  Conventionally, when a portable device such as an electronic key is inserted into a slot by a driver at the time of starting a vehicle engine or the like, electronic authentication that the inserted electronic key or the like is a dedicated key for the vehicle A technique (electronic key function) is known that permits starting when authentication is established. In addition, when the vehicle engine is started, the driver who carries the portable device presses the start switch, so that the driver can authenticate with the electronic key etc. through mutual communication without inserting the electronic key into the slot. A technology (smart function) for performing start and permitting start is known. A vehicle equipped with both a smart function and an electronic key function is also known.

  In a vehicle equipped with both the smart function and the electronic key function, when the smart function is used and the authentication is not established due to a decrease in the battery mounted on the electronic key or a poor communication state, the engine is Can be started. That is, in the smart function, for example, authentication is performed by receiving a request signal transmitted from the vehicle to the vehicle interior via a transmission / reception means included in the portable device, and transmitting an authentication code in response to the request signal. At this time, the transmission / reception means of the portable device is driven by a power source such as a battery mounted on the portable device, but becomes inoperable due to a decrease in the battery. On the other hand, in the electronic key function, for example, when a portable device is inserted into a slot and a driving radio wave is received by the portable device, an electromotive force is generated in the portable device, and a predetermined authentication code is transmitted for authentication. Even if there is no drive power supply on the portable device side, it can operate. Therefore, by using the smart function and the electronic key function together, a more reliable system can be provided.

For this reason, a technique for switching between the smart function and the electronic key function has been proposed. For example, there is a technique for switching to an electronic key function when it is determined that authentication by the smart function is not established (see, for example, Patent Document 1). In the technique of this Patent Document 1, the driver switches to the electronic key function by operating the start switch in a state where it is determined that the authentication by the smart function is not established. Further, as another technique different from the technique of Patent Document 1, for example, a sensor that detects that an electronic key has been inserted into a slot is provided, and when it is detected that an electronic key has been inserted into a slot, Technology that can be switched from a function to an electronic key function.
JP 2004-359057 A

  However, in the apparatus of Patent Document 1, the electronic key function is a control used in an emergency. On the other hand, some drivers may use the electronic key function more frequently. However, in the device of Patent Document 1, it is necessary for the driver to switch to the electronic key function by operating the start switch for switching in a special state where it is determined that authentication by the smart function is not established. For this reason, when the driver wants to use the electronic key function, there is a problem in that switching to the electronic key function is not easily performed and convenience is not good.

  On the other hand, in the technology that switches from the smart function to the electronic key function according to the detection result of the key insertion detection sensor or the like, the driver switches to the electronic key function only by inserting the electronic key into the slot. , Convenience is improved. However, this technique has a problem that it is difficult to start the engine when the sensor fails because it depends on the detection result of the key insertion detection sensor. In other words, if the key insertion detection sensor erroneously detects that the key has been inserted even though it has not been inserted, it will be switched to the electronic key function. If an operation such as insertion into the slot is not performed, the engine cannot be started. In addition, when the key insertion detection sensor erroneously detects that the key is inserted but not inserted, it does not switch to the electronic key function.For example, when the battery is low and the smart function does not operate, The engine cannot be started.

  In view of the above circumstances, the present invention switches between the smart function and the electronic key function without requiring a switching operation by the driver, and properly authenticates with the portable device even when the insertion of the portable device is erroneously detected. An object of the present invention is to provide a vehicle control device that can be executed to start a drive source such as an engine.

A vehicle control device according to the present invention is provided in a vehicle and is operated when a drive source of the vehicle can be started, and a vehicle is connected to the vehicle by first communication. A slot into which a portable device having a function of performing communication and a function of performing mutual communication with the vehicle by second communication is inserted; and the portable device is inserted into the slot on condition that the start switch is operated. A portable device insertion detecting means for detecting whether the portable device is inserted and the first communication with the portable device electronically authenticates that the portable device is a portable device registered in advance in the vehicle. That the portable device is a portable device registered in advance in the vehicle by the second communication between the first authentication means for executing the first authentication process and the portable device inserted into the slot. Second to authenticate electronically A second control unit that executes an authentication process; a start control unit that can start the drive source of the vehicle when authentication is established by at least one of the first and second authentication units; and at least wherein when the portable device is detected as not being inserted into the slot by the portable device insertion detecting means includes an authentication control unit configured to perform a first authentication process to the first authentication means, wherein the portable device is In the first communication, a request signal transmitted from the vehicle to a predetermined first area is received and power supplied from a power source mounted on the portable device is used, whereas in the second communication, The present invention relates to a vehicle control device that receives a driving radio wave transmitted to a second area inside the slot and uses electric power generated by the driving radio wave .

In this vehicle control device, when the portable device insertion detection unit detects that the portable device is inserted in the slot, the authentication control unit performs a second authentication process on the second authentication unit. And the first authentication unit when the second authentication process does not establish authentication even though the portable device insertion detection unit detects that the portable device is inserted into the slot. Thus, the first authentication process is executed.

  In this vehicle control device, when the portable device insertion detection means detects that the portable device is not inserted into the slot, the first authentication process (corresponding to the smart function) using the first communication is executed, For example, it is authenticated whether or not a portable device such as an electronic key is a portable device (a dedicated portable device for a vehicle) registered in advance in the vehicle. Thus, when the driver wants to authenticate without inserting the portable device into the slot, the authentication process is efficiently performed according to the driver's request. When the authentication by the first authentication unit is established, the drive source can be started by the start control unit without performing the second authentication process.

  On the other hand, the driver can arbitrarily select the authentication process, and may wish to authenticate by inserting the portable device into the slot. Therefore, the authentication control unit causes the second authentication unit to execute the second authentication process (corresponding to the electronic key function) when the portable device insertion detection unit detects that the portable device is inserted into the slot. . As a result, when the driver wants to authenticate by inserting the portable device into the slot, the authentication process is efficiently performed according to the driver's request. When the authentication is established by the second authentication means, the drive source can be started by the start control means without performing the first authentication process by the first authentication means.

  At this time, if it is detected by the portable device insertion detection means that the portable device is inserted into the slot, but the authentication is not established by the second authentication means, the portable device is inserted into the slot due to a failure of the portable device insertion detection means or the like. In spite of not being inserted, it is assumed that it is erroneously detected as being inserted. That is, in this situation, since the portable device is not actually inserted into the slot, authentication is not established by the second authentication process. In such a situation such as failure of the portable device insertion detection means, authentication can be performed by using the smart function. Therefore, when the second authentication unit does not authenticate when the portable device insertion detection unit detects that the portable device is inserted into the slot, the authentication control unit sets the first authentication unit to the first authentication unit. Execute authentication process. Thereby, even when it is erroneously detected that the portable device is inserted due to a failure of the portable device insertion detecting means, the drive source can be started.

Therefore, according to the present invention, the smart function and the electronic key function can be switched without requiring a switching operation by the driver, and even if it is erroneously detected that the portable device is inserted, It is possible to appropriately execute the above-described authentication and to start a drive source such as an engine.
In addition, the first predetermined area is, for example, the vehicle interior of the vehicle, and the first authentication process can be performed by establishing communication with the first communication only by the driver carrying the portable device entering the vehicle interior. It becomes. However, since the first communication is performed using electric power supplied from a power source such as a battery mounted on the portable device, the first communication becomes impossible due to a decrease in the battery. On the other hand, the second predetermined area is, for example, in a slot. When the driver inserts the portable device into the slot and receives the driving radio wave with the portable device, mutual communication is established by the second communication, and the second predetermined region is established. Authentication processing is possible. Since the second communication is performed using power generated by the driving radio wave, the second communication can be performed without a driving power source on the portable device side, and more stable communication can be performed because the area is relatively narrow. Therefore, for example, when the battery of the portable device is low or the communication of the first communication is poor, the driver can start the drive source by selecting the second authentication process using the second communication. Become. Therefore, according to the present invention, it is possible to easily switch between the two types of authentication processing using the two types of communication, respectively, and the authentication processing is appropriately executed even when the portable device insertion detection means is erroneously detected. Since it becomes possible, the convenience of the driver can be greatly improved.

  In the vehicle control device of the present invention, the authentication control means performs authentication by the first authentication process when the portable machine insertion detecting means detects that the portable machine is not inserted into the slot. If not established, it is preferable to cause the second authentication means to execute a second authentication process.

  In other words, if the portable device insertion detection means detects that the portable device is not inserted into the slot, but the first authentication means fails to authenticate, the portable device insertion detection means may be Although the machine is inserted, it is assumed that a mobile device is not inserted and is erroneously detected. In this situation, for example, when the driver tries to authenticate by inserting the portable device into the slot due to malfunction of the first communication, the authentication is not established by the first authentication process. In such a situation such as failure of the portable device insertion detection means, authentication can be performed by using the electronic key function. Therefore, the authentication control means sets the second authentication means to the second authentication means when authentication is not established by the first authentication process when it is detected by the portable machine insertion detection means that the portable machine is not inserted into the slot. The authentication process is executed. Thereby, even if it is erroneously detected that the portable device is not inserted due to a failure of the portable device insertion detecting means, etc., it is possible to appropriately execute authentication with the portable device and to start a drive source such as an engine. it can.

As shown in FIG. 1, the vehicle control system includes an electronic key 10 that is an example of a portable device of the present invention and a vehicle control device 20 mounted on the vehicle 1. The vehicle control system authenticates whether or not the electronic key 10 is a key registered in advance in the vehicle 1 by performing mutual communication with the electronic key 10 and starts the engine or the like when the authentication of the electronic key 10 is established. System.

  The vehicle control device 20 controls a slot 21, a start switch 23, and a slot 21 into which the electronic key 10 is inserted, and a slot ECU (electronic control unit) that authenticates the electronic key 10 inserted into the slot 21. 22, smart ECU 30 for authenticating the electronic key 10 not inserted in the slot 21, LF antennas 31 and 32 for performing wireless communication in the LF (low frequency) band with the electronic key 10, and the electronic key 10 RF unit 33 that performs wireless communication in the RF (radio frequency) band, power supply control unit 25 that controls power supply, fuse box 26 connected to power supply control unit 25, and locking / unlocking of the steering wheel Electric steering lock ECU for switching, and An engine ECU 27 that controls the engine is provided. The vehicle control device 20 is connected to a starter motor 28 for igniting the engine and a steering lock mechanism 34 for locking the steering handle. These components are connected via a communication line 40.

  As shown in FIG. 2A, the electronic key 10 is a card type and is possessed by a user (driver) of the vehicle 1 and can be inserted into and removed from the slot 21. Further, as shown in FIG. 1, the electronic key 10 includes a communication unit 12 and a control unit 13 for mutual communication with the vehicle control device 20 through first communication described later, and a power to the communication unit 12 and the control unit 13. A power supply 14 for supplying power is incorporated. The communication unit 12 receives signals transmitted from the LF antenna 32 and the RF unit 33 and outputs received data to the control unit 13. The control unit 13 generates response data according to the input reception data and outputs the response data to the communication unit 12. Then, the communication unit 12 transmits the response data as a signal to the RF unit 33. In addition, the electronic key 10 incorporates a transponder 11 for communicating with the vehicle control device 20 through second communication described later. The transponder 11 receives a predetermined driving radio wave transmitted from the LF antenna 31 to generate an electromotive force, and transmits a response signal including a predetermined identification code to the LF antenna 31 using the electromotive force.

  As shown in FIG. 2A, the slot 21 has a rectangular parallelepiped shape, and a key insertion space opened in the side surface 21a of the slot 21 for inserting the electronic key 10 is formed inside. The slot 21 is disposed on an instrument panel provided in front of the passenger compartment so that it can be operated by the driver in the vicinity of the steering wheel. Specifically, the slot 21 is arranged so that the side surface 21a is exposed on the instrument panel, and the electronic key 10 can be inserted and removed. FIG. 2B shows a state where the electronic key 10 is inserted into the slot 21. At this time, a part of the electronic key 10 is exposed to the outside of the slot 21.

  Further, as shown in FIG. 1, the slot 21 has a key insertion detection switch 41 for detecting whether or not the electronic key 10 is inserted in the slot 21, and the inserted electronic key 10 does not fall out of the slot 21. And a key fixing device 42 for fixing as described above.

  The key insertion detection switch (portable device insertion detection means of the present invention) 41 is a mechanical contact type switch, and is arranged in the slot 21 so that the movable part of the switch is exposed. When the electronic key 10 is inserted into the slot 21, the movable part of the key insertion detection switch 41 is pressed, and a key insertion detection signal is output from the key insertion detection switch 41 to the power supply control unit 25, the slot ECU 22, and the smart ECU 30.

  The key fixing device 42 is constituted by a plunger provided so as to advance and retract into the slot 21. An engagement recess is formed on one side surface of the electronic key 10, and the plunger is provided at a position facing the engagement recess when the electronic key 10 is inserted into the slot 21. When the plunger is advanced, the electronic key 10 is engaged with the engaging recess of the electronic key 10, whereby the electronic key 10 cannot be detached from the slot 21 and is fixed to the slot 21.

  The start switch 23 is a switch operated by the driver when the engine can be started, when the engine is started, or when the engine is stopped. The start switch 23 is a push button switch, and is provided in the vicinity of the steering handle so that the pressing portion is exposed from the instrument panel. When the start switch 23 is pressed, a pressing operation signal is output to the power supply control unit 25, the slot ECU 22, and the smart ECU 30.

  The slot ECU 22 controls the key fixing device 42 based on the detection result of the key insertion detection switch 41 and the lock / unlock state of the electric steering ECU 29. More specifically, the slot ECU 22 outputs a key insertion detection signal from the key insertion detection switch 41, and when the electric steering ECU 29 is in the unlocked state, the key fixing device 42 is turned on (the electronic key 10 is fixed). ).

  Further, the slot ECU 22 performs mutual communication with the electronic key 10 by the second communication. In the second communication, the slot ECU 22 outputs a driving radio wave having a predetermined frequency (for example, 125 kHz) to the inside of the slot 21 (second region) via the LF antenna 31. The electronic key 10 receives the driving radio wave and transmits a response signal including a predetermined identification code. The transmitted response signal is received by the LF antenna 31 and output to the slot ECU 22.

  In addition, the slot ECU 22 functions as an electronic key authentication process (second recognition process) for electronically authenticating that the electronic key 10 is a portable device registered in advance in the vehicle 1 using the second communication. The second authentication means 51 for performing the above is provided. The second authentication means 51 executes an electronic key authentication process when an authentication execution signal described later is input from the power supply control unit 25. In the electronic key authentication process, the second authentication means 51 performs second communication with the electronic key 10 inserted in the slot 21 and acquires an identification code. Then, the second authentication means 51 performs authentication by comparing the acquired identification code with a previously registered identification code. The second authentication unit 51 sends an authentication establishment signal to the power supply control unit 25 when the authentication is established (specifically, when the identification code is acquired and coincides with the registered identification code within a predetermined time). Output.

  The smart ECU 30 performs mutual communication with the electronic key 10 by the first communication. In the first communication, the smart ECU 30 outputs a request signal having a predetermined frequency (for example, 125 kHz) to the passenger compartment (first region) of the vehicle 1 via the LF antenna 32. The electronic key 10 receives the request signal and transmits a response signal having a predetermined frequency (for example, 311.9 MHz) including the ID information of the electronic key 10. The transmitted response signal is received by the RF unit 33 and output to the smart ECU 30. Furthermore, the smart ECU 30 transmits a signal including ID information and an encryption code corresponding to the ID information via the RF unit 33. The electronic key 10 receives a signal including ID information and an encryption code, and transmits a response signal including a predetermined identification code. The transmitted response signal is received by the LF antenna 32 and output to the slot ECU 22.

  In addition, the smart ECU 30 performs, as its function, a smart authentication process (first recognition process) for electronically authenticating that the electronic key 10 is a portable device registered in advance in the vehicle 1 using the first communication. First authentication means 50 is provided. The first authentication means 50 executes smart authentication processing when an authentication execution signal described later is input from the power supply control unit 25. In the smart authentication process, the first authentication means 50 performs the first communication described above with the electronic key 10 and acquires an identification code. Then, the first authentication means 50 performs authentication by comparing the acquired identification code with a previously registered identification code. The first authentication means 50 sends an authentication establishment signal to the power supply control unit 25 when the authentication is established (specifically, when the identification code is acquired and coincides with the registered identification code within a predetermined time). Output.

  The power supply control unit 25 controls power supplied to each part of the vehicle control system or outputs a control signal to each part, and is connected with a fuse box 26 for preventing excessive power from being supplied. Has been.

  The power control unit 25 has, as its function, an authentication control means 53 that causes the first and second authentication means 50 and 51 to execute authentication processing under a predetermined condition, and an engine that can be started when authentication is established. And start control means 54.

  The authentication control means 53 outputs an authentication execution signal to the slot ECU 22 and the smart ECU 30 based on the operation state of the start switch 23, the detection result of the key insertion detection switch 41, and the authentication state by the slot ECU 22 and the smart ECU 30. The first and second authentication means 50 and 51 are caused to execute authentication processing.

  The start control means 54 performs a start control process that allows the engine of the vehicle 1 to be started when authentication is established by at least one of the first and second authentication means 50 and 51. Specifically, when an authentication establishment signal is input from the slot ECU 22 or the smart ECU 30, the start control unit 54 outputs a lock release signal to the electric steering lock ECU 29 to make it possible to start the engine.

  Further, in a state where the engine can be started, the power supply control unit 25 outputs an engine start signal to the engine ECU 27 when a pressing operation signal is input from the start switch 23 with the brake of the vehicle 1 being depressed, for example. The power supply control unit 25 outputs an engine stop signal to the engine ECU 27 when a pressing operation signal is input from the start switch 23 while the engine is being driven, that is, when a complete explosion signal described later is input from the engine ECU 27. At the same time, the supply of power to the engine ECU 27 is stopped and a lock signal is output to the electric steering lock ECU 29.

  The electric steering lock ECU 29 controls the steering lock mechanism 34 of the vehicle 1 according to the output from the power supply control unit 25 to switch between the locked state and the unlocked state of the steering handle. Specifically, when the electric steering lock ECU 29 receives a lock signal from the power supply control unit 25, the electric steering lock ECU 29 controls the steering lock mechanism 34 so that the steering handle of the vehicle 1 cannot be operated (locked state), and the power supply control unit 25. When a lock release signal is input from, the steering lock mechanism 34 is controlled so that the steering wheel can be operated (unlocked). Further, the electric steering lock ECU 29 outputs to the slot ECU 22 and the smart ECU 30 whether the locked state or the unlocked state is present.

  When an engine start signal is input from the power supply control unit 25, the engine ECU 27 performs control of fuel injection and processing for controlling ignition by controlling the starter motor 28 (engine start processing). Further, after starting the engine, the engine ECU 27 detects the driving state of the engine based on an ignition pulse, an alternator output, and the like, and outputs a complete explosion signal to the power supply control unit 25 when determining that the engine is driven. . The engine ECU 27 continues to output a complete explosion signal to the power supply control unit 25 while the engine is being driven. Further, the engine ECU 27 stops the engine when an engine stop signal is input from the power supply control unit 25.

  The slot ECU 22, the power control unit 25, the engine ECU 27, the electric steering lock ECU 29, and the smart ECU 30 are not shown in detail. An electronic processing unit composed of an arithmetic processing circuit composed of a circuit or the like, or a microcomputer in which these functions are integrated).

  The functions of these electronic units are realized by causing the computer to execute a program previously installed in the memory of the computer. The program may be stored in the memory via a storage medium such as a CD-ROM. The program may be distributed or broadcast from an external server via a network or an artificial satellite, and may be received by a communication device mounted on the vehicle 1 and stored in a memory.

  Next, the operation (authentication / startup control processing) of the vehicle control system realized by the vehicle control device 20 of the present embodiment will be described using the flowchart shown in FIG. In the authentication / startup control process, authentication with the electronic key 10 is executed, and a process for starting the engine is executed when the authentication is established. This authentication / startup control process is periodically repeated at a predetermined control cycle when the electronic key 10 is not authenticated.

  Referring to FIG. 3, first, vehicle control device 20 determines whether or not start switch 23 is in an on state (STEP 1). If the determination result in STEP 1 is NO (the start switch 23 is not pressed), the authentication / startup control process ends.

  If the determination result in STEP 1 is YES (the start switch 23 has been pressed), the vehicle control device 20 determines whether the key insertion detection switch 41 is in an on state (a state in which a key insertion detection signal is output). It is determined whether or not (STEP 2).

  If the determination result in STEP 2 is NO, it is assumed that the electronic key 10 is not inserted into the slot 21. In this case, proceeding to STEP 3, the vehicle control device 20 executes the smart authentication process described above. Thus, when the driver wants to authenticate without inserting the electronic key 10 into the slot 21, the authentication process is efficiently performed according to the driver's request.

  Next, proceeding to STEP 4, the vehicle control device 20 determines whether or not authentication is established as a result of the smart authentication process. If the determination result in STEP 4 is YES (authentication is established), the process proceeds to STEP 11 and a start control process described later is executed. As a result, when the authentication by the smart authentication process is established, the engine can be started in STEP 11 described later without performing the electronic key authentication process.

  On the other hand, when the determination result of STEP 4 is NO (authentication is not established), the process proceeds to STEP 5 and the vehicle control device 20 executes the above-described electronic key authentication process. As a result, even when the electronic key is inserted due to a failure of the key insertion detection switch 41 or the like, the authentication process is executed even if the electronic key cannot be detected.

  Next, proceeding to STEP 6, the vehicle control device 20 determines whether or not authentication is established as a result of the electronic key authentication process. If the determination result in STEP 6 is YES (electronic key authentication is established), the process proceeds to STEP 11 and a start control process described later is executed. As a result, even if the electronic key is inserted due to a failure of the key insertion detection switch 41 or the like but cannot be detected as being inserted, the engine can be started in STEP 11 described later.

  If the determination result in STEP 6 is NO (electronic key authentication is not established), the authentication / startup control process ends.

  On the other hand, if the determination result in STEP 2 is YES, it is assumed that the electronic key 10 is inserted in the slot 21. In this case, proceeding to STEP 7, the vehicle control device 20 first executes an electronic key authentication process. The details of the electronic key authentication process in STEP 7 are the same as those in STEP 5. Thus, when the driver wants to insert the electronic key 10 into the slot 21 for authentication, the authentication process is efficiently performed according to the driver's request.

  Next, proceeding to STEP 8, the vehicle control device 20 determines whether or not authentication is established as a result of the electronic key authentication process. If the determination result in STEP 8 is YES (electronic key authentication is established), the process proceeds to STEP 11 and a start control process described later is executed. As a result, when the authentication by the electronic key authentication process is established, the engine can be started in STEP 11 described later without performing the smart authentication process.

  On the other hand, when the determination result in STEP 8 is NO (authentication is not established), the process proceeds to STEP 9 and the vehicle control device 20 executes smart authentication processing. The details of the smart authentication process are the same as those in STEP 3. Thus, even if the electronic key is not inserted due to a failure of the key insertion detection switch 41 or the like, the authentication process is executed even if it is erroneously detected as being inserted.

  Next, it progresses to STEP10 and the vehicle control apparatus 20 judges whether authentication was materialized as a result of the electronic key authentication process. If the determination result in STEP 6 is YES (electronic key authentication is established), the process proceeds to STEP 11 and a start control process described later is executed. As a result, even if the electronic key is inserted due to a failure of the key insertion detection switch 41 or the like but cannot be detected as being inserted, the engine can be started in STEP 11 described later.

  If the determination result in STEP 10 is NO (smart authentication is not established), the authentication / startup control process ends.

  As described above, when the authentication is established by the authentication processes of STEPs 4, 6, 8, and 10, the process proceeds to STEP 11, and the vehicle control device 20 executes the start control process and ends the authentication / control process.

  Through the above processing, the smart function and the electronic key function are switched without requiring a switching operation by the driver, and even when the key insertion detection switch 41 is erroneously detected, the authentication with the electronic key 10 is appropriately executed, and the engine Can be made startable.

  In this embodiment, the engine can be started by one start switch 23 and the engine is further started. However, in another embodiment, a switch for starting the engine and the engine are started. A separate switch may be provided.

  In this embodiment, the start switch is a push button switch, and the button is pressed to enable the engine to start or the engine is started. However, as another embodiment, for example, a start switch is As a knob (momentary push button switch), the engine can be started by pressing the knob, and the engine can be started by rotating the knob.

  In the present embodiment, the start switch is pressed by the driver to perform the authentication process and the engine can be started. However, as another embodiment, for example, the electronic key 10 is not provided with the start switch. When the insertion into the slot 21 is detected by the key insertion detection switch 41, an authentication process may be performed so that the engine can be started.
