Description

  The present invention relates to a door lock control device capable of preventing a key confinement state in which a door is locked while leaving a key in a vehicle interior.

  2. Description of the Related Art Conventionally, there has been known a system in which a door lock mechanism can be remotely operated from the outside when a key confinement trouble occurs. In this system, a wireless signal receiving means is provided in the automobile, and a security confirmation device is provided in the management company. When the management company receives an inquiry from the user through the telephone line, it sends the driving signal for the unlocking operation to the vehicle radio signal receiving means on condition that the user is identified by confirming the registered confirmation items, and the door lock The mechanism is operated remotely. With this configuration, even if an engine key or remote control is locked in the passenger compartment of a car, the user can unlock it by using a public communication network such as a telephone network. (For example, refer to Patent Document 1).

  In addition, if the door key cannot be used for some reason, as in the case of the key confinement problem described above, the door can be operated by pushing and pulling the door knob (input order and number of inputs). An automobile door lock releasing device that can release the lock is also known (see, for example, Patent Document 2).

JP 2000-324252 A Japanese Unexamined Patent Publication No. 01-310074

  The technique disclosed in Patent Document 1 has the following problems. For example, if the key is locked in the back of a mountain where there is no public phone nearby (and a mobile phone cannot be used), that is, the public communication network cannot be used, the door can be opened by remote control as described above. Unable to unlock. Therefore, in such a case, the door cannot be opened quickly unless the spare key is always carried around.

  Further, in the technique of performing door knob operation outside the vehicle according to a preset operation procedure as in Patent Document 2, when a vehicle user parks the vehicle and is away, a third party (that is, a user other than the vehicle user) By repeatedly performing the door knob operation for a long time, there is a possibility that the method of releasing the door lock will be known. Further, when the user of the vehicle is performing an unlocking operation of the door, there is a possibility that the operation procedure will be seen by a third party and the unlocking method of the door will be known. As a result, there is a security concern that the door can be unlocked without permission by the vehicle user.

  In view of the above problems, an object of the present invention is to provide a door lock control device that can quickly unlock a door when a key confinement state occurs while improving crime prevention.

  In order to solve the above-described object, the door lock control device according to claim 1 determines that a key capable of locking or unlocking the door is present in the vehicle interior of the vehicle when the vehicle door is in a locked state, and When it is authenticated that the user is a vehicle user by operating a vehicle member provided outside the vehicle compartment, the door is controlled to be unlocked, and it is determined that there is no key in the vehicle compartment. In this case, the door is controlled to be kept locked regardless of the operation of the vehicle member.

  According to this configuration, when the door is in the locked state and the key is in the passenger compartment, the user can be quickly unlocked by performing user authentication based on the operation of the vehicle member. It is possible to prevent others from unlocking the door without permission from the user.

  If the door is locked and the key is not in the passenger compartment, the door is locked. In other words, by prohibiting user authentication by operating the vehicle members except in an emergency such as key confinement, the possibility of others unlocking the door can be prevented more reliably, and crime prevention can be further improved. Can be increased. That is, in the case of general parking in which the user takes the key out of the passenger compartment and locks the door, the key is not detected in the passenger compartment, so even if the user authentication is known to a third party, the door is locked. The crime prevention property can be improved in order to continue.

  Therefore, when the key confinement state occurs, the door can be unlocked quickly while improving the security.

  The door lock control device according to claim 2 receives door opening / closing data for inputting door opening / closing data, and determines whether or not all the doors are closed by inputting the opening / closing data. If it is determined that the door is in the closed state, the door is controlled to lock after a certain period of time has elapsed since the doors are all closed, regardless of whether or not the key is present in the passenger compartment. Yes.

  According to this configuration, regardless of whether or not the key is in the passenger compartment, when a certain period of time has elapsed since the door is closed, the door is locked so that another person can inadvertently enter the passenger compartment. Intrusion can be suppressed and crime prevention can be further improved.

  Further, the vehicle member used for detecting whether or not a predetermined operation of the door lock control device according to claim 3 is performed is a door knob of the door, a switch provided on the door, or a door mirror having an opening / closing movable function. It is characterized by being.

  According to this configuration, even if the key is confined in the vehicle compartment, such as a door knob or switch provided on the door outside the vehicle compartment, or a door mirror provided near the door outside the vehicle compartment, By using the functions provided in the vehicle for user authentication, the door can be unlocked quickly without taking the trouble of preparing a spare key separately.

  Hereinafter, the connection relationship of each component will be described focusing on a verification ECU (ECU: Electronic Control Unit) 10.

  The verification ECU 10 (corresponding to the door lock control device of the present invention) includes a body ECU (FR, FL, RR, RL, trunk) 11 prepared for each vehicle door and an in-vehicle LAN (LAN: Local Area Network) 40. Are connected so as to be able to communicate with each other based on a predetermined communication standard (for example, CAN (Controller Area Network) communication). Further, the verification ECU 10 includes a touch sensor (not shown) provided for each door knob 21 of the door (FR, FL, RR, RL, trunk) 20 outside the passenger compartment of the vehicle, and each door knob 21. The trigger switch 22 and the vehicle-mounted LAN 40 are communicably connected to each other (the door knob 21 and the trigger switch 22 correspond to the vehicle member of the present invention).

  The verification ECU 10 is communicably connected to a plurality of tuners 31 provided in the passenger compartment or trunk (not shown) via a communication line. Further, a plurality of verification ECUs 10 are installed in the vicinity of the center of the vehicle interior, in the vehicle interior transmitter 32, and in the vicinity of the door knob 21 of each door, the central part of the rear bumper (not shown), and the like. The vehicle interior transmitter 33 is communicably connected via a communication line.

  Each of the body ECUs (FR, FL, RR, RL, trunk) 11 is a drive device configured to lock / unlock the door, which is configured inside the door (FR, FL, RR, RL, trunk) 20. Are connected to each other via a communication line.

  The door lock control system 1 includes a tuner 31, an ID key 30 that can be carried in the vehicle interior or the exterior of the vehicle and can perform ID (Identification: a code for identifying a specific individual) communication. The wireless transmitter 32 and the outdoor transmitter 33 are configured to be capable of wireless communication.

  For the abbreviations FR, FL, RR, and RL used in the above description, in this embodiment, FR = Front Right (front right side of the vehicle), FL = Front Left (front left side of the vehicle), RR = Rear Right (vehicle) RR = Rear Left (the rear left side of the vehicle).

  Next, the function of each component will be described. Hereinafter, unless otherwise specified, the body ECUs (FR, FL, RR, RL, trunk) 11 having the same functions are referred to as body ECUs 11, and the doors (FR, FL, RR, (RL, trunk) 20 is omitted and referred to as door 20.

  The verification ECU 10 transmits a request signal for performing ID code verification and position confirmation of the ID key to the ID key 30 via the vehicle interior transmitter 32 or the vehicle interior transmitter 33. Further, the ID code of the ID key 30 received from the tuner 31 is discriminated and collated, and a command signal corresponding to the result is transmitted to each ECU such as the body ECU 11. Details of the verification ECU 10 will be described later with reference to FIG.

  The body ECU 11 detects the open / closed state of the door 20 by a door sensor that detects opening / closing of the door, detects the locked / unlocked / unlocked state of the door, and transmits the detection result to the verification ECU 10. . The body ECU 11 is configured to drive the door lock motor to execute the lock / unlock of the door 20 when receiving a command signal for instructing the lock / unlock of the door 20 from the verification ECU 10. .

  Although not shown, the ID key 30 has a wireless communication function. When a request signal is received from the vehicle interior transmitter 32 or the vehicle exterior transmitter 33, the ID key 30 includes a response code using the wireless communication function. 31. The ID key 30 is provided with a switch (not shown) that can instruct locking / unlocking of the door 20 (including the trunk) by a wireless communication function. It is configured to allow remote unlocking.

  The tuner 31 receives the ID code from the ID key 30 using the wireless communication function, and transmits it to the verification ECU 10.

  The vehicle interior transmitter 32 transmits a request signal received from the verification ECU 10 using a wireless communication function, and enters a predetermined range (for example, a radius of about 0.5 m from the transmitter 32) into the vehicle interior (including within the trunk). The detection area is formed. In the present embodiment, the vehicle interior transmitter 32 is installed in a plurality of vehicle interiors to detect whether an ID key is present in the vehicle interior space.

  The transmitter 33 for outside the vehicle transmits a request signal received from the verification ECU 10 by using a wireless communication function, and has a predetermined range outside the cabin (including outside the trunk) (for example, a range having a radius of about 1.0 m from the transmitter 33). The detection area is formed.

  Note that the detection area of the vehicle interior transmitter 32 and the detection area of the vehicle exterior transmitter 33 are transmitted by controlling the detection direction so that they do not cross each other (such as having directivity).

  The door knob 21 is configured to be able to unlock the door just by touching it. Specifically, a touch sensor (not shown) is provided on the back surface of the door knob 21. When the touch sensor detects that it has been touched, it transmits a detection signal indicating the detection to the verification ECU 10. Although details will be described later, the verification ECU 10 controls to unlock the door based on the detection signal.

  The trigger switch 22 is configured to lock the door when the switch is pressed. Specifically, when it is detected that the switch has been pressed, a detection signal indicating the detection is transmitted to the verification ECU 10. Although details will be described later, the verification ECU 10 controls to unlock the door based on the detection signal.

  As will be described later, the door knob 21 and the trigger switch 22 are also used for inputting a password for unlocking the door by being operated according to a predetermined procedure. Operation data indicating the procedure) is transmitted to the verification ECU 10.

  Next, the verification ECU 10 will be described in more detail using the block diagram of the verification ECU 10 of FIG.

  The input / output interface unit 10a includes a communication I / F (communication interface) having a communication driver and a communication controller for communicating with the body ECU 11 via the in-vehicle LAN 40, a tuner 31, a vehicle interior transmitter 32, or a vehicle exterior transmission. The main component is an I / O (input / output unit) for communicating with the machine 33.

  The control unit 10b is configured as a well-known microcomputer. Although not shown, the control unit 10b includes a ROM that is a memory that records a program describing processing contents, a CPU that executes the program recorded in the ROM, and processing data temporarily. A RAM or the like for storing is configured.

  The recording unit 10c is communicably connected to the control unit 10b, and an authentication table is prepared in the recording unit 10c. In this authentication table, an operation procedure using at least one of the door knob 21 and the trigger switch 22 known only by the vehicle user is registered in advance.

  In addition, the user said here means the person who can use a vehicle regularly, such as a vehicle owner, a family of an owner, and the person who permitted the owner.

  The authentication table will be specifically described below. As shown in FIG. 3, two tables (10c (1), 10c (2)) data are recorded in the recording unit 10c. The tables 10c (1) and 10c (2) are used when the control unit 10c detects that the door 20 is locked and the ID key 30 is in the passenger compartment.

  Both the tables 10c (1) and 10c (2) have door positions (FR, RL, trunk, etc.) in order of operation procedure numbers (1 → 2 → 3 →...) For unlocking the doors. ), The selected operation procedure of the vehicle member (door knob, trigger switch) is recorded. More specifically, the operation procedure of the table 10c (1) will be described below in the unlocking operation order (1 to 5).

  In number 1, the door knob provided in the door (FR) is operated once.

  In number 2, the door knob provided in the door (RL) is operated once.

  In number 3, the door knob provided on the door (trunk) is operated once.

  In number 4, the trigger switch provided in the door (FR) is operated once.

  In number 5, the trigger switch provided on the door (FL) is operated once.

  If the user operates the same operation procedure as the unlocking operation sequence stored in advance under a predetermined condition, the door is unlocked.

  The basic configuration of the other table 10c (2) is the same as that of the table 10c (1), and detailed description thereof is omitted. However, the door position is fixed (FR) at the same place, and the number of operations is determined. Is less than the table 10c (1). This is used when user authentication is desired with a simple operation procedure.

  That is, although user authentication is possible using either the table 10c (1) or the table 10c (2), the table 10c (1) with higher security is used in this embodiment.

  The operation data registered in the authentication table can be input corresponding to each position information of the authentication table or operation of each vehicle member using an input device (not shown) such as a touch panel. It can be registered from a device connected via a line.

  The recording unit 10c can also record operation data obtained by operating the vehicle member (the door knob 21 or the trigger switch 22) after the control process of FIG. 5 described later starts (however, the temporary recording process). So it may be recorded in RAM).

  For reference, basic control means for unlock control of the door 20 using the door knob 21 and lock control of the door 20 using the trigger switch 22 in the verification ECU 10 will be described.

  First, the unlock control of the door 20 unlocks the door 20 when the door knob 21 is operated when the ID key 30 is outside the passenger compartment.

  First, the verification ECU 10 receives a signal indicating the closed state of the door 20 from each body ECU 11. Next, the verification ECU 10 activates a plurality of outdoor transmitters 33 installed near the door knob 21 and the rear bumper central portion (not shown). Each of the vehicle exterior transmitters 33 intermittently emits a radio wave having a specific frequency (a hundred and several tens kHz). When the ID key 30 enters the detection area outside the passenger compartment and receives radio waves, the ID key 30 returns an ID code to the vehicle with radio waves of a specific frequency (several hundreds of MHz). The verification ECU 10 determines and collates the ID code of the ID key 30 received by the tuner 31. When the collation is matched, the collation ECU 10 activates a touch sensor (not shown) and puts the door 20 into the standby state. When the touch sensor detects that the door knob 21 has been touched and receives the detection signal, the verification ECU 20 transmits an unlock signal for unlocking the door 20 to each body ECU 11. And each body ECU11 will drive a door lock motor, respectively, and will unlock a door, if the unlock signal is received.

  On the other hand, the lock control of the door 20 locks the door 20 when the trigger switch 22 is operated and the ID key 30 exists outside the passenger compartment (not in the passenger compartment).

  First, when an engine (not shown) is off and the door 20 is all closed, the operation starts when any trigger switch 22 of the door 20 is pressed. When receiving the instruction signal from the trigger switch 22, the verification ECU 10 transmits a request signal to each vehicle interior transmitter 32 and each vehicle interior transmitter 33. Based on the request signal from the verification ECU 10, each vehicle interior transmitter 32 and each vehicle exterior transmitter 33 form a detection region for detecting the ID key 30. The verification ECU 10 determines and collates the ID code of the ID key 30 received by the tuner 31. By this collation, the collation ECU 10 confirms that the ID key 30 is outside the vehicle compartment by detecting that the vehicle compartment collation matches and the vehicle interior collation does not match. Then, the verification ECU 10 transmits a lock signal for locking the door 20 to each body ECU 11. When the body ECU 11 receives the lock signal, the body ECU 11 drives the door lock motors to lock the doors.

  By the way, as described above, in order to prevent key confinement, if the lock signal is not continuously transmitted (set to the unlocked state) while the key is in the passenger compartment, the user of the vehicle leaves the vehicle. There is a risk that a third person such as a third person may enter the vehicle interior. Therefore, in this embodiment, an automatic lock process as shown in FIG. 4 is performed.

  FIG. 4 is a flowchart for automatically locking the door in the verification ECU 10. First, when a signal of opening / closing data indicating that the door has changed from the closed state to the open state is input from each body ECU 11, the process starts.

  In step S1, it is determined whether or not all the doors are closed by the input of opening / closing data. If all the doors are not closed, step S1 is repeated. If all the doors are closed, the process proceeds to step S2. Here, “all doors are closed” means “all doors that can enter the passenger compartment are closed”.

  In step S2, counting of the time until the door is locked is started.

  In step S3, information on whether or not the door 20 is unlocked is received from each body ECU 11, and if it is determined that at least one of the doors 20 is unlocked (YES), the process proceeds to step S4. . On the other hand, if it is determined (NO) that all the doors are in the locked state (that is, the door 20 is not in the unlocked state), the process ends (end).

  In step S4, it is determined whether or not a fixed time has elapsed (for example, 30 seconds) since the door was closed. If the predetermined time has not elapsed, the processes of step S3 and step S4 are repeatedly executed. If the predetermined time has elapsed, the process proceeds to step S5.

  In step S5, in order to lock the door, a lock signal is transmitted to each body ECU 11, and the process ends (END). Each body ECU 11 drives each door lock motor based on the received lock signal, whereby all doors of the door 20 are locked.

  As described above, regardless of whether the ID key 30 is inside or outside the vehicle interior, the door 20 is automatically locked when a certain period of time has passed, so that a third person such as a third person can enter the vehicle interior. Can be suppressed.

  Next, a control process (corresponding to the door lock control device of the present invention) of the verification ECU 10 of the present embodiment will be described using the flowchart of FIG. Here, the process is started when the verification ECU 10 receives a detection signal from the touch sensor of the door knob 21 of one of the doors 20 (in this case, the door (FR)). However, the start of this process is not limited to this, and may be when, for example, a detection signal of the trigger switch 22 of the door (FR) is received.

  In step S10, based on the input of the signal indicating the locked / unlocked state received from each body ECU 11, it is determined whether or not all the doors 20 are locked. If it is determined that all are locked (YES), the process proceeds to step S11, and if it is detected that all are not locked (NO), at least a part of the doors are unlocked or the doors are opened. The process is terminated (end) because it is in a state that can be opened. Note that “all the doors 20 are locked” means that, among the doors provided in the vehicle, all the doors that can enter the passenger compartment are locked.

  In step S11, based on the input of the signal from the tuner 31, it is determined whether or not the ID key 30 is in the passenger compartment. If it is detected that the ID key 30 is in the vehicle interior, the process proceeds to step S12. If the ID key 30 is not present in the vehicle interior (that is, the ID key 30 cannot be detected), the process proceeds to step S13.

  In step S12, “input operation procedure recorded in advance” in the authentication table of FIG. 3 and detection signals (operation data) by the operation of the door knob 20 and the trigger switch 22 after the start of the process are input. “Operation procedure of vehicle member” is verified (that is, authentication is performed with a password). As a result of the collation, when it is detected that the operation procedure is the same, it is authenticated (authenticated as a vehicle user) as a specific individual (determined as YES), and the process proceeds to step S14. On the other hand, if it is detected that the operation procedure is not the same, it is authenticated (NO) that it is not a specific individual (not a vehicle user), and the process proceeds to step S13.

  In step S12, the operation procedure of the vehicle member that is input after the start is provided with a time limit (for example, 5 minutes), and the process may be forcibly terminated when the time has elapsed. Further, when it is forcibly terminated or when it is detected that the operation procedure is not the same (NO), the verification ECU 10 controls to sound a warning sound to a horn (not shown) connected to the verification ECU 10 via a communication line. Also good.

  In step S13, each body ECU 11 is not instructed to unlock the doors 20 (actual processing does nothing in order to continue the locked state), and the process ends (END).

  In step S14, each body ECU 11 is instructed to unlock the door 20 (that is, the verification ECU 10 transmits an unlock signal and is received by the body ECU 11), and the process ends (END). The body ECU 11 that has received the unlock signal unlocks each door 20 to change the door state from the locked state to the unlocked state.

  Hereinafter, effects according to the present embodiment will be described. For example, consider a door lock control device capable of unlocking a door only by an authentication method for performing authentication by operating a vehicle member. However, in such a control device, a third person who does not know the predetermined operation repeatedly performs the operation for a long time, so that it may eventually reach the predetermined operation and unlock the door. There is.

  Therefore, in this embodiment, only when the ID key 30 is in the vehicle compartment, the door can be unlocked after confirming the authentication by operating the vehicle member. In other words, if the ID key 30 is not in the vehicle cabin, it is possible to prevent other people who do not have the ID key 30 from unlocking the door without permission from the user. However, crime prevention can be further improved.

  Further, by using the vehicle member provided in advance in the vehicle as an authentication means for unlocking the door 20, even if the ID key 30 remains in the passenger compartment and is locked as it is, the spare key can be used at home. The door can be opened quickly without taking time and effort to return to the factory.

  Regardless of whether or not the ID key 30 is inside or outside the vehicle compartment, when a predetermined condition (in this embodiment, a fixed time has elapsed) is satisfied, all doors of the door 20 are locked. Since the door 20 can be unlocked by authentication using a vehicle member provided in the vehicle, both crime prevention and convenience can be realized.

  As another authentication method in which only a specific individual can reliably unlock the door 20 even when the ID key 30 is confined, for example, as disclosed in Patent Document 1, a mobile phone, a public telephone, a vehicle service center, It is also possible to unlock the door by remotely operating the vehicle when communication for authenticating the password is performed and it is determined that the password is identified as a specific individual. However, in a situation where a mobile phone and a key are confined in a mountainous area where there is no public telephone, for example, the door cannot be unlocked by remote control, so the door cannot be opened quickly. In the present embodiment, by using a vehicle member provided in advance in the vehicle as the authentication means, the key confinement state can be avoided at an early stage even in the above-described situation and in the situation where no spare key is carried around.

  As described above, according to the present embodiment, in the door lock control device capable of bringing the door into an unlocked state when it is detected that there is a key in the passenger compartment, when a key confinement state occurs while improving security. The door can be unlocked quickly.

  The present invention is not limited to the above-described embodiments, and can be applied without departing from the gist of the invention according to each claim.

  For example, part or all of the functions of the verification ECU 10 may be realized by the body ECU 11 or another ECU.

  In addition, the vehicle members (door knob 21 and trigger switch 22) are not limited to those described above, and may be a door mirror (not shown) provided in advance near the door of the vehicle, for example. When the door mirror is used as a vehicle member, the folding state or the open state of the door mirror is detected by a sensor, and the detected signal is transmitted to the verification ECU 10.

  Further, although the operation of the door knob 21 indicated by the “operation” item in FIG. 3 defines the operation of pulling the knob once, it is not limited to this and may be defined as the operation of pulling the knob twice or three times. Similarly, the trigger switch 22 means an operation of pressing the switch once, but may be defined as an operation of pressing the switch a few times.

  Furthermore, in addition to the original function (the door lock / unlock function described in this embodiment, the door mirror opening / closing movable function described in another example, etc.), is the vehicle member of this embodiment a specific individual? It is also used as an authentication member for authenticating whether or not. As described above, if vehicle members such as the door knob 21, the trigger switch 22, and the door mirror that are originally provided in the vehicle are also used for authentication, the cost of newly providing a dedicated member for authentication can be reduced. Can do. However, the vehicle member of the present invention does not have to be limited to such dual use, and a dedicated authentication switch or the like may be newly provided outside the vehicle cabin as a dedicated vehicle member for authentication. .

  Further, the operation data obtained by performing the password-like operation is not limited to this, and it is only necessary to authenticate whether or not the user is a user. For example, a function capable of detecting fingerprint data or voice data instead of operation data is provided as a vehicle member, and based on the input result of the fingerprint data or voice data, it is determined that an operation for authenticating the user of the vehicle has been performed. Also good.
