Description

The present invention relates to a vehicle door control device and a control system for accepting a reservation for automatically locking a vehicle door and executing the locking.

In the past, when locking the doors of a vehicle, an operation was performed to lock the doors after waiting for the vehicle doors to close. Vehicle door controls have emerged that automatically lock the doors.

For example, in the vehicle door control device disclosed in Patent Document 1, when the user operates the door operation switch to automatically close the vehicle door, further operating the door lock switch automatically closes the door. A reservation to lock automatically (hereinafter referred to as "reservation lock") is accepted. If a predetermined lock condition is satisfied, the door is automatically locked, and if the lock condition is not satisfied, an alarm is output without automatically locking the door. The lock conditions include that the door is closed and that the user's electronic key is not inside the vehicle.

Further, in the vehicle door control device disclosed in Patent Document 2, when at least one of a plurality of doors provided in the vehicle is open and at least one door is closed, When the user operates a lock switch provided on the closed door, the position of the portable device owned by the user is detected. At this time, when it is detected that the mobile device is not inside the vehicle but outside the vehicle, the reservation lock is accepted and the automatic lockable mode is entered. Then, when a predetermined lock condition (all doors are closed and no portable device is inside the vehicle) is met, all doors are automatically locked. In addition, the buzzer outside the vehicle sounds different times when reservation lock is accepted, when lock condition failure is detected, and when the doors are automatically locked.

JP 2018-150734 A Japanese Patent No. 5173499

If the door is not automatically locked because the predetermined locking condition is not met after the reserved locking of the vehicle door is accepted, and the user leaves the vehicle without realizing it, a malicious third party can unlock the door. There is a risk of intrusion into the vehicle compartment by opening the door in a state. At that time, if the electronic key of the vehicle is left behind in the vehicle, there is a risk that the engine of the vehicle will be started by a malicious third party and the vehicle will be stolen. As a countermeasure against this, in Patent Document 1, an alarm is output when the lock condition is not satisfied. However, if the user can appropriately respond to the warning, there is no problem, but the user may be confused by the sudden warning and may not be able to take an appropriate response. Moreover, if the output of the alarm continues for a long time, it will become a nuisance to the surroundings. On the other hand, if the alarm can be stopped by a simple operation that anyone can do, such as opening a door or operating a switch one time, the crime prevention performance will be low.

The present invention provides a vehicle door control device and a control system that can easily be handled by a user and can ensure high crime prevention when a vehicle door cannot be automatically locked based on a reservation lock. The challenge is to

According to the vehicle door control device and control system as described above, after receiving a reservation for automatically locking the vehicle doors, if the lock conditions are not met, the doors are unlocked and an alarm is output. However, the input requesting unit requests the user to input through the input unit for canceling the alarm. Then, when a specific input unique to the user is performed by the input section, the control section cancels the alarm. Therefore, the user can cancel the alarm by a simple operation of performing a specific input through the input unit. In addition, it is possible to prevent the output of the alarm from continuing for a long time and causing annoyance to the surroundings. Then, after the warning is released, the user can take appropriate measures, such as solving the reason why the reserved door locking was not realized, or reserving the door locking. Furthermore, even if the electronic key of the vehicle is inside the vehicle, for example, the alarm will not be canceled unless a specific input is made through the input unit, so crime prevention can be enhanced.

In the present invention, the input requesting section may request the input of a password as the specific input, and the control section may cancel the alarm when the specific password is input by the input section.

Further, the present invention further includes a door open/close detection unit for detecting an open/closed state of the door, and when the door open/close detection unit detects that the door is open when the lock condition is not satisfied, The controller may output an alarm. In this case, the controller may output an alarm when a predetermined period of time has elapsed since the door open/close detector detected that the door was open.

Further, in the present invention, the input requesting unit may request a specific input while the alarm is being output, and the control unit may continue outputting the alarm unless a specific input is performed by the input unit.

Alternatively, the input requesting unit may request a specific input before outputting the alarm, and the control unit may output the alarm unless a specific input is performed by the input unit.

Further, in the present invention, the input section may be provided in an in-vehicle device electrically connected to the vehicle door control device. In this case, the input requesting unit displays a display requesting a specific input on the display unit provided in the in-vehicle device, and the control unit acquires the content input by the input unit from the in-vehicle device, and confirms that the content of the input is correct. It may be determined whether or not the contents of a specific input match.

Alternatively, the input unit may be provided in a mobile device carried by the user. In this case, the vehicle door control device further includes a communication unit that wirelessly communicates with the mobile device, and the input requesting unit transmits information requesting a specific input to the mobile device by the communication unit. When the communication unit receives an alarm cancellation request displayed on the display unit and transmitted from the mobile device in response to a specific input by the input unit, the control unit may cancel the alarm. . Further, before outputting the alarm, the control unit may transmit information indicating the alarm standby state to the mobile device through the communication unit and display it on the display unit of the mobile device.

Furthermore, in the present invention, the control unit may cancel the alarm after a predetermined time has passed since the output of the alarm was started.

FIG. 3 is a flow chart showing the operation of the vehicle door control device 10 of the first embodiment. Each step of this flowchart is executed by the control unit 11 .

In FIG. 3, as described above, the reservation lock reception unit 13 is configured to operate the door operation switch 31 and the door lock switch 32 continuously in two steps, and to confirm that the electronic key 20 is in one of the vehicle exterior communication areas Zb during the operation. is detected, and reservation locking of the doors 51 and 52 is accepted (step S1; YES). Then, the control unit 11 determines whether or not a predetermined lock condition is satisfied (step S2).

At this time, the control unit 11 tries to communicate with the electronic key 20 via the antennas 17A and 17B of the LF/UHF communication unit 17, and the key position detection unit 12 detects the position of the electronic key 20 based on the communication result. to detect Further, the control unit 11 detects the open/closed state of each of the doors 51 and 52 using the door open/close detection unit 14 .

For example, when the key position detection unit 12 detects that the electronic key 20 is not in the vehicle interior 55 and the door opening/closing detection unit 14 detects that all the doors 51 and 52 are closed, the control unit 11 determines that the lock condition is satisfied (step S2: YES). In this case, the controller 11 locks all the doors 51 and 52 by the door lock device 35 (step S3). That is, the accepted reservation lock is realized (reservation lock success).

On the other hand, for example, the key position detector 12 detects that the electronic key 20 is inside the vehicle compartment 55, or the door open/close detector 14 detects that at least one of the doors 51 and 52 is open. If so, the control unit 11 determines that the lock condition is not satisfied (step S2: NO). In this case, the controller 11 leaves all the doors 51 and 52 as they are (step S4). As a result, among all the doors 51 and 52, the doors that have already been locked are locked, and the doors that were not locked are unlocked. That is, the accepted reservation lock is not realized, and at least one of the doors 51 and 52 is unlocked (reservation lock failure).

Also, when the reservation lock fails, the control unit 11 outputs an alarm from the alarm device 36 (step S5). This warning is given by, for example, sounding the buzzer or horn of the vehicle 50 included in the warning device 36, or by turning on/blinking the lights of the vehicle 50, or the like.

During the output of the alarm, the input request unit 15 communicates with the navigation device 37 via a CAN (Controller Area Network) or the like to display a password input screen 60 (FIG. 4) for requesting input of a password for canceling the alarm. It is displayed on the touch pad 38 of the device 37 (step S6).

FIG. 4 is a diagram showing a password input screen 60. As shown in FIG. As shown in FIG. 4, the password input screen 60 is provided with a message 61 requesting input of a password for resetting an alarm, a password input field 62, and a plurality of soft keys 63-66. Of the soft keys 63 to 66 , a plurality of soft keys 63 are keys for inputting numbers, alphabets, or symbols into the input field 62 . A soft key 64 is a key for switching information input by each soft key 63 . The soft key 65 is a key for deleting (cancelling) information such as a number once input by the soft key 63 . A soft key 66 is a key for determining the entered password.

In FIG. 4A, since numbers (“0” to “9”) are displayed on each soft key 63, by touching each soft key 63, the number corresponding to the operated soft key 63 is displayed. is entered. By touching the soft key 64 in FIG. 4(a), an alphabetic character or a symbol is displayed on each soft key 63 as shown in FIG. 4(b). In FIG. 4B, by touching each soft key 63 once or multiple times, an alphabetic character or symbol corresponding to the operated soft key 63 is input. For example, by touching the soft key 63 displaying "ABC" once, twice, or three times, lowercase letters "a", "b", or "c" are input, four times, An English capital letter "A", "B" or "C" is input by performing a touch operation five times or six times. Further, in FIG. 4(b), by touching the soft key 64, numbers are displayed on each soft key 63 as shown in FIG. 4(a).

When a number, alphabet, or symbol is entered by touching the soft key 63, "*" is displayed instead of the input information in the entry field 62, as shown in FIG. 4(b). When the soft key 66 is touched, the input information (character string) is determined as a password and transmitted from the navigation device 37 to the control section 11 .

When receiving (acquiring) a password from the navigation device 37, the input determination unit 16 compares the password with a predetermined password stored in advance. When both passwords match, the input determining unit 16 determines that the correct password for resetting the alarm has been input (step S7 in FIG. 3: YES). In this case, the control unit 11 cancels the warning from the warning device 36 (stops the output of the warning) (step S8). The input requesting unit 15 also transmits a display stop command to the navigation device 37 to stop (turn off) the display of the password input screen 60 by the touch pad 38 (step S9).

On the other hand, when the password is not input on the password input screen 60, or when the password is input but does not match the predetermined password, the input determination unit 16 determines the correct password for canceling the alarm. It is determined that no password has been entered (step S7: NO). In this case, the output of the warning by the warning device 36 and the display of the password input screen 60 by the touch pad 38 are continued.

According to the above-described first embodiment, after receiving a reservation lock for automatically locking the doors 51 and 52 of the vehicle 50, at least one of the doors 51 and 52 is unlocked if a predetermined lock condition is not satisfied. A locked state is entered, and an alarm is output from the alarm device 36 . Accordingly, the input requesting unit 15 displays a password input screen 60 on the touch pad 38 of the navigation device 37 installed in the vehicle compartment 55, and requests the user to input a password for canceling the alarm. Then, when the user operates the touch pad 38 and inputs a correct password known only to the user, the warning by the warning device 36 is canceled.

Therefore, the user can stop the alarm output by the alarm device 36 by performing a simple operation of entering the correct password on the password input screen 60 of the touch pad 38 . In addition, it is possible to prevent the output of the alarm by the alarm device 36 from continuing for a long time and causing annoyance to the surroundings. In addition, after the alarm is released, the user can take appropriate measures, such as solving the reason why the reserved doors 51 and 52 were not locked, or reserving the locking of the doors 51 and 52. . Furthermore, for example, even if the electronic key 20 is inside the vehicle compartment 55, if the correct password is not entered on the password entry screen 60 of the touch pad 38, the alarm device 36 continues to output an alarm. Therefore, it is possible to improve crime prevention and prevent a malicious third party who does not know the correct password for releasing the alarm from stealing the vehicle 50 or articles in the vehicle.

Further, in the above-described first embodiment, the input requesting unit 15 causes the touch pad 38 of the navigation device 37 to display the password input screen 60 while the warning device 36 is outputting the warning. Therefore, even if an alarm is output by the alarm device 36 because the lock condition is not satisfied, the user can view the password input screen 60 and enter the correct password for canceling the alarm. It can be stopped quickly. If the correct password is not entered on the password entry screen 60, the alarm device 36 continues to output an alarm. Therefore, even if a malicious third party who does not know the correct password inputs incorrect information on the password input screen 60, the alarm device 36 can continue to output an alarm, thereby further enhancing crime prevention.

FIG. 5 is an electrical block diagram of the vehicle door control system 100 of the second embodiment. In FIG. 5, a smart phone 40 carried by a user of a vehicle 50 is used instead of the navigation device 37 of FIG.

In FIG. 6, steps S11 to S17 are provided instead of steps S6, S7, and S9 in FIG. Further, in FIG. 6, step S10 is added after step S4.

In FIG. 6, in the vehicle door control device 10, after steps S1, S2, and S4, the controller 11 detects the open/closed state of the doors 51 and 52 by the door open/close detector 14 (step S10). Here, when the door opening/closing detection unit 14 detects that at least one of the doors 51 and 52 is open (step S10: YES), the control unit 11 causes the alarm device 36 to output an alarm. (Step S5).

Then, the input requesting unit 15 requests the input of the password for resetting the alarm, so the BLE communication unit 18 transmits the data of the password input screen 60 shown in FIG. 4 to the smartphone 40 (step S11).

In the smartphone 40, when the data of the password input screen 60 is received by the BLE communication unit 42 (step S12: YES), the control unit 41 displays the password input screen 60 on the touch pad 43 (step S13). At this time, the smartphone 40 may output sound or vibrate the smartphone 40 to notify the user that the password input screen 60 is displayed on the touch pad 43 .

When the user operates the touch pad 43 to input a password on the password input screen 60, the input determination unit 44 compares the password with a predetermined password stored in advance. When both passwords match, the input determination unit 44 determines that the correct password for resetting the alarm has been input (step S14: YES). In this case, the control unit 41 transmits a request (signal) to cancel the alarm to the vehicle door control device 10 through the BLE communication unit 42 (step S15), and stops (turns off) the display of the password input screen 60 (step S16).

On the other hand, when the user does not enter a password on the password entry screen 60 or when the password is entered but does not match the predetermined password, the input determination unit 44 outputs an alarm reset command. It is determined that the correct password has not been entered (step S14: NO). In this case, the display of the password input screen 60 by the touch pad 43 and the output of the warning by the warning device 36 are continued.

In the vehicle door control device 10, after step S11, when the BLE communication unit 18 receives the request to cancel the alarm transmitted from the smartphone 40 (step S17: YES), the control unit 11 cancels the alarm by the alarm device 36. (step S8).

According to the above-described second embodiment, even if the lock condition is not satisfied after the reservation lock is accepted and the alarm device 36 outputs an alarm, the input request unit 15 causes the touch pad 43 of the smartphone 40 to display the password input screen. 60 is displayed to request the user to enter a password to clear the alarm. Then, when the user operates the touch pad 43 and inputs a correct password known only to the user, the warning by the warning device 36 is canceled. Therefore, the user can stop the alarm output by the alarm device 36 by performing a simple operation of entering the correct password on the password input screen 60 of the touch pad 43, and the alarm can be stopped. It is possible to prevent the output from being a nuisance to the surroundings. Also, even if the electronic key 20 is inside the vehicle compartment 55, if the correct password is not entered on the password input screen 60 of the touch pad 43, the alarm device 36 outputs an alarm. Therefore, it is possible to improve crime prevention, and to prevent the vehicle 50 and articles in the vehicle from being stolen by a malicious third party who does not know the correct password.

Further, in the above-described second embodiment, when the lock condition is not satisfied, the alarm device 36 detects that one of the doors 52, 52 is open, after the door open/close detector 14 detects that the door is open. An alarm is output. For this reason, there is a risk that a third party may enter the vehicle interior 55 due to the presence of the doors 51 and 52 that are left open, or the door 51 that is closed but left unlocked. When a third person opens the door 52 and enters the vehicle compartment 55 , the alarm device 36 can reliably output an alarm to notify the user and others around the vehicle 50 . Further, when the lock condition is not satisfied, the alarm device 36 does not output an alarm while the doors 51 and 52 are left closed. battery power can be reduced.
