Description

  The present invention relates to an electronic component control apparatus for a vehicle.

  As a control device for controlling electronic components such as an actuator for operating a sliding door of a vehicle, those described in Patent Documents 1 and 2 are known. The conventional example described in Patent Document 1 is configured to control the operation of the electric sliding door, and includes an acceleration sensor incorporated in the electronic key and a transmission circuit that outputs a control signal to the control unit of the vehicle. . When the electronic key is shaken, the acceleration line sensor detects the direction of the electronic key, generates a door opening or closing operation signal according to the detected movement direction of the electronic key, and outputs the signal from the transmission circuit to the vehicle control unit.

  However, the above-described conventional example has a problem that the structure of the electronic key is complicated because the direction in which the electronic key is swung is detected by a sensor housed in the electronic key. Since it is possible from a position away from the vehicle, there is a problem that safety may occur when the operation of the electronic components of the vehicle is controlled by this, and there is a problem that the application range is limited.

  That is, when the driving of the electric sliding door described in Patent Document 1 can be executed by the control signal output from the electronic key, the electric door at the position where it becomes a blind spot from the electronic key operating position is accidentally opened / closed, which is inadvertent. Because there is a danger of inducing an accident, it is necessary to carefully check the surroundings.

  In the conventional example described in Patent Document 2, a plurality of capacitance sensors are arranged on a door handle of a vehicle, and the electric door is driven by a swipe direction with respect to the capacitance sensor row. In order to operate the electric door, the safety problem associated with the remote operation is low as in the conventional example described in the conventional example 1, but the operation authority for the operation of the electric door cannot be authenticated. There is a problem that the operation of the door cannot be prevented.

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a vehicle electronic component control device with high operational safety.

According to the present invention, the object is
A vehicle electronic component control device for controlling an electronic device mounted on a vehicle,
RFID passive tag 1,
An antenna arrangement unit 4 arranged in a vehicle by arranging a plurality of antennas 3 connected to an RFID reader 2 capable of authenticating the RFID passive tag 1;
The movement path of the RFID passive tag 1 within the communicable range with the antenna arrangement unit 4 is detected by the authentication order of the RFID passive tag 1 at each antenna 3 and is assigned in advance to the detected movement pattern of the RFID passive tag 1. A control unit 5 for controlling the operation of the electronic device by outputting the actuated signal to a predetermined electronic device;
This is achieved by providing an electronic component control device for a vehicle having the following.

  In the present invention, the antenna array unit 4 is arranged in a vehicle. When the antenna array unit 4 is traced in a predetermined locus in a non-contact state by the RFID passive tag 1, each antenna 3 of the antenna array unit 4 is RFID passive. Communication with the RFID passive tag 1 is started in the order in which the tag 1 enters the communication range, and the RFID passive tag 1 is authenticated.

  When the RFID reader 2 connected to each antenna 3 of the antenna array unit 4 can authenticate the RFID passive tag 1, in other words, when the RFID passive tag 1 has a predetermined ID, The RFID reader 2 can determine the authentication order in the corresponding antenna 3 and, as a result, can specify the moving path and direction of the RFID passive tag 1.

  The control unit 5 that detects the movement path and direction of the RFID passive tag 1 searches a preset “movement pattern” vs. “operation object” and “operation content” table, and responds to an operation command that matches the movement pattern. Output to the electronic device. The operation target can be determined as appropriate, such as the electric door 6, the indoor light, and the locking / unlocking of the glove box, and the operation content includes selection of opening / closing of the electric door 6, selection of turning on / off the indoor light, glove box If the operation target is one type, “movement pattern” vs. “operation content” is set.

  Further, the antenna arrangement unit 4 can be arranged in a matrix form other than arranging the antennas 3 in a straight line. When the antennas 3 are arranged in a straight line, for example, RFID from left to right is used. Open the electric door 6 to the movement pattern of the passive tag 1, close it to the movement pattern in the reverse direction, move the movement from left to right, and then move the movement pattern to the left again. In the case where they are arranged in a plane, the operation target and the operation content can be identified by the movement pattern including the oblique direction and the vertical direction.

  Further, since the RFID passive tag 1 is used, a special power source is not required, and a small chip shape is also provided. Therefore, it is very easy to downsize the apparatus.

  As described above, in the present invention in which the movement of the RFID passive tag 1 is detected by the antenna arrangement unit 4 disposed in the vehicle and the required operation is determined, the communication distance with the RFID passive tag 1 is relatively short. In addition, each electronic device is controlled within a range where the surroundings of the vehicle can be sufficiently looked at, so that the operation at the blind spot position can be surely prevented, and safety can be improved.

  Further, in order to capture the movement path of the RFID passive tag 1 as a control signal, it is necessary to authenticate the RFID reader 2 to which the RFID passive tag 1 is set. Operation is reliably prevented.

  Furthermore, since the RFID passive tag 1 can exchange IDs in a non-contact state with respect to the antenna arrangement unit 4, the hands are not soiled during operation.

The electric door control device for a vehicle adopting the above control device is
An electric door control device for a vehicle that controls opening and closing of an electric door 6 of a vehicle driven between opening and closing positions,
RFID passive tag 1,
An antenna arrangement unit 4 in which a plurality of antennas 3 connected to an RFID reader 2 that can authenticate the RFID passive tag 1 are arranged, and a movement path of the RFID passive tag 1 within a communication range with the antenna arrangement unit 4 The RFID passive tag 1 is detected by the authentication order of each antenna 3 and the operation signal pre-assigned to the detected movement pattern of the RFID passive tag 1 is output to the electric door 6 to control the opening / closing operation of the electric door 6. A control unit 5 to perform,
Can be configured.

  The RFID passive tag 1 can use an RFID tag used in an authentication system that has already been introduced into a vehicle. For example, when the vehicle employs an immobilizer system, the RFID reader 2 of the present invention, and By configuring the antenna arrangement unit 4 so that the transponder in the immobilizer key can be authenticated, the electric door 6 can be opened and closed by operating the antenna arrangement unit 4 with the immobilizer key.

  When the electronic key 7 for unlocking the electric door 6 uses an RFID tag as an authentication means, the RFID reader 2 and the antenna array unit 4 of the present invention are connected to the electronic unlock key. By configuring the RFID so that it can be authenticated, the RFID can function as the RFID passive tag 1 of the present invention, and the unlocking operation of the electric door 6 can be performed by operating the antenna array unit 4 with the electronic key 7 for locking operation. It becomes possible to do.

  As mentioned above, the case where the RFID tag used in the authentication system already introduced in the vehicle is used as the RFID passive tag 1 has been described, but in addition to this, the immobilizer key used in the authentication system or the electronic device for lock operation A configuration in which the RFID passive tag 1 of the present invention is added to the key 7 is also possible. In this case, by adding the ID of the added RFID passive tag 1 as an authenticable object in the authentication device, the RFID passive tag 1 All operations including unlocking operations can be performed.

  By adding an unlocking operation function to the RFID passive tag 1 attached to the lock operation electronic key 7 capable of unlocking the electric door 6, for example, the same RFID tag used for an electronic key for residential use is used. When the RFID tag that outputs the ID of the RFID tag is added to the electronic key 7 for lock operation as the RFID passive tag 1 of the present invention, in addition to the unlocking operation of the electric lock device for residence using the electronic key 7 for lock operation, Unlocking the vehicle and other operations can also be made possible.

When the RFID passive tag 1 is attached to the electronic key 7 for lock operation,
The RFID passive tag 1 constitutes an electric door control device for a vehicle that outputs an ID different from the lock operation electronic key 7 for unlocking the electric door 6 and is attached to the lock operation electronic key 7. With this configuration, only the holder of the electronic key for lock operation 7 to which the RFID passive tag 1 is attached can be operated to the handle device 9 provided as standard in the vehicle, or the lock operation can be performed. In addition to this, it is possible to provide an optional opening / closing operation method of the electric door 6 to the opening / closing operation method of the electric door 6 by the electronic key 7, and in addition to this, it is possible to grant the authority to lock and unlock the glove box.

in this case,
If the RFID passive tag 1 is formed in a chip shape that can be attached to the electronic key 7 for operation of the lock, the RFID passive tag 1 can be used by attaching it to the case surface of the electronic key 7 for operation of the lock provided as a standard by the user. Therefore, the electronic key for the electric door control device can be made without any change to the electronic key 7 for operation of the lock. Further, when the RFID passive tag 1 is detachable, for example, when a vehicle is rented to an acquaintance or the like, operations that can be performed only by the RFID passive tag 1 such as locking and unlocking of a glove box can be limited. improves.

  When the RFID passive tag 1 that outputs an ID that can be authenticated by the authentication unit that authenticates the operation authority for the house lock device is used, the lock operation of the house lock device is performed using the lock operation electronic key 7. Can also be done.

  Further, the antenna arrangement part 4 can be configured by fixing the vehicle door panel itself or a member holding the antenna arrangement part 4 to the door panel. However, if the antenna arrangement part 4 is provided on the operation handle 8 for operating the electric door 6, it feels uncomfortable in design. Decrease.

  According to the present invention, since an operation at a position close to the vehicle is requested, it is possible to improve operational safety and to control electronic components without directly touching the vehicle. The operation can be performed without soiling.

It is explanatory drawing which shows this invention. It is a flowchart which shows operation | movement of a control part. It is a block diagram which shows the modification of FIG. It is explanatory drawing which shows the other modification of FIG.

  FIG. 1 shows an embodiment of the present invention configured as an electric door control device that controls opening and closing of an electric slide door (electric door 6) of a vehicle. A handle device 9 for opening and closing the slide door 6 and a door lock device 10 for locking the slide door 6 are mounted on the slide door 6. The handle device 9 is formed by connecting the operation handle 8 to a handle base 10 a fixed to the panel of the slide door 6.

  In order to electronically perform the locking / unlocking operation of the door lock device 10, a keyless entry control unit 11 that can be operated by a lock operation electronic key 7 possessed by a user is disposed in the vehicle. The lock operation electronic key 7 has an ID transmission unit 7a accommodated in the case. When the lock / unlock operation button 7b disposed in the case is pressed, unique ID information is output from the ID transmission unit 7a. The

  When the ID information output from the lock operation electronic key 7 is received by the antenna 11a stored in the operation handle 8, the keyless entry control unit 11 compares the ID information with the pre-registered ID information. A locking or unlocking command signal is output to 12, and the door lock device 10 is operated to lock and unlock.

  Further, the keyless entry control unit 11 can control the opening / closing operation of the sliding door 6 in addition to the control for the door lock device 10, and when the operation button 10b disposed on the handle base 10a is pressed, the ID request is made from the antenna 11a. A signal is output to the lock operation electronic key 7. Upon receiving the ID request signal, the lock operation electronic key 7 outputs ID information from the ID transmission unit 7a, and when the keyless entry control unit 11 authenticates the ID information, the door lock device 10 is in the locked state, and the sliding door When the door 6 is in the closed state, first, an unlock command is output to the lock control unit 12 to cause the door lock device 10 to transition to the unlocked state, and then a door open command is output to the door drive control unit 13 to open the door. The actuator of the drive device 14 is driven to open the slide door 6.

  When the operation button 10b is pressed while the slide door 6 is in the open state, the keyless entry control unit 11 outputs a door closing command to the door drive control unit 13 to drive the actuator of the door drive device 14, and the slide door. After closing 6, a lock command is output to the lock control unit 12 to drive the door lock device 10 to the locked state.

  On the other hand, the electric door control device according to the present example is provided to add a function to the keyless entry control unit 11, and each of the antenna arrangement unit 4 provided on the operation handle 8 of the handle device 9 and the antenna arrangement unit 4 is provided. The RFID reader 2 connected to the antenna 3, an operation control unit (control unit 5), a pattern storage unit 15, and the RFID passive tag 1 are included.

  Since the RFID passive tag 1 itself does not require a driving power supply, it is formed in a chip shape and is attached to the electronic key 7 for lock operation. The RFID passive tag 1 outputs ID information in response to a request signal output from the RFID reader 2. In this example, the RFID passive tag 1 can output ID information required when performing locking / unlocking operation of a residential electric lock, and can lock / unlock a residential electric lock.

  The antenna array unit 4 is composed of a plurality of antennas 3, and in this example, two antennas 3 are arranged at both longitudinal end positions of the operation handle 8 that is long in the vehicle length direction. Each antenna 3 is accommodated in the operation handle 8 in the same manner as the antenna 11a controlled by the keyless entry control unit 11 described above.

  The RFID reader 2 outputs a request signal from the antenna 3 in the antenna array unit 4 and then waits for a response from the RFID passive tag 1 for a predetermined time. When the RFID reader 2 receives the response signal from the RFID passive tag 1, the ID information included in the response signal is checked against previously registered ID information, and if they match, an authentication establishment signal is output.

  Further, the RFID reader 2 can identify which of the antenna information received by the antenna arrangement unit 4 has been authenticated, and the operation control unit 5 has been authenticated within a predetermined time. The order of the antennas 3 is acquired as the movement pattern of the lock operation electronic key 7.

  The pattern storage unit 15 is a table in which the movement pattern acquired by the operation control unit 5 is associated with the control contents. When the operation control unit 5 acquires the movement pattern, the movement pattern acquired by the pattern storage unit 15 is displayed. If a matching pattern is searched, the corresponding control is executed.

  In this example, the pattern storage unit 15 has an opening operation of the slide door 6, that is, a movement pattern from the vehicle head side toward the rear side. The sliding movement of the sliding door 6 is assigned to the forward movement pattern, but in addition to this, a locking action is added in the case of the closing movement, or the movement from the vehicle head side to the tail side is performed. Subsequently, the unlocking operation to the glove box can be assigned to the reciprocating movement pattern that returns to the vehicle head side again, and the locking operation of the glove box can be assigned to the reciprocating movement pattern in the reverse direction.

  FIG. 2A shows an operation flow of the operation control unit 5 configured as described above. First, the operation control unit 5 monitors the output of an open / close detection unit (not shown) that detects the open / close state of the slide door 6 (step S1), and when the open / close detection unit outputs the door open state, In preparation for the detection of the closing operation, a request signal is output from the antenna arrangement unit 4 (step S2), and the start of communication with the RFID passive tag 1 attached to the lock operation electronic key 7 is awaited (step S3).

  On the other hand, when the closed state is detected in step S1, the keyless entry control unit 11 waits for an unlocking operation (step S11), and outputs a request signal.

  When communication with the RFID passive tag 1 is confirmed in step S3, a timer is started (step S4), and the authentication state of the RFID passive tag 1 in the antenna array unit 4 is recorded in time series, and after a predetermined time has elapsed. (Step S5), a movement pattern is specified from the recording during this time (Step S6).

  The movement pattern specified in step S6 is searched in the pattern storage unit 15 (step S7). If there is a matching pattern (step S8), is the control signal from the keyless entry control unit 11 output? Whether or not is detected (step S9). If no matching pattern is detected in step S8, an appropriate error signal is output (step S81), and a retry is prompted. For the error signal, a buzzer or the like that is called when the lock operation electronic key 7 is left in the vehicle can be used.

  When the control signal from the keyless entry control unit 11 is not output in step S9, there is no possibility that the control via the operation control unit 5 by the electric door control device and the control via the keyless entry control unit 11 are batting. For this purpose, a control signal is immediately generated and the control content corresponding to the movement pattern is executed (step S10). On the other hand, when a control signal is output from the keyless entry control unit 11 and this control content and the control content via the operation control unit 5 by the electric door control device are batting (step S91), both Without performing the control, an error signal is output (step S81) to prompt a retry.

  In the above, the case where the control in the electric door control device is limited to the opening / closing operation of the slide door 6 has been described, but the locking / unlocking operation in the door lock device 10 may be added to the control target. In this case, as shown in FIG. 3, the control signal from the operation control unit 5 can control the lock control unit 12 and the door drive control unit 13 in the same manner as the control signal from the keyless entry control unit 11. Yes, a movement pattern for locking and unlocking is registered in the pattern storage unit 15.

  In this case, as shown in FIG. 2B, the operation control unit 5 sets the start of communication between the lock operation key and the keyless entry control unit 11 as a request signal transmission start condition (step T1). S2 and subsequent steps can be executed.

  In the above description, an example in which the antenna array unit 4 incorporates a plurality of antennas 3 in the operation handle 8 of the slide door 6 to be operated is shown. Other than the handle, for example, it can be arranged on a front operation handle, a side door mirror, or a door side panel. As shown in FIG. 4, one antenna 3 ′ of the antenna array section 4 composed of a plurality of antennas 3 is provided on the operation handle 8 ′ of the handle device 9 ′ arranged on the front door 6 ′. It is possible. Thus, by arranging the plurality of antennas 3 at more isolated positions, the authentication order of the antennas 3 can be obtained more accurately.
