Below, functions performed by the processor 110 of the vehicle door lock release system 100 according to an embodiment of the present invention will be described in detail.

Figure 3 is a block diagram for explaining the functions performed by the processor of the vehicle door lock release system according to an embodiment of the present invention, and Figures 4 and 5 are a vehicle door lock release system according to an embodiment of the present invention. This is a diagram to explain the process of unlocking the door using .

For reference, some or all of the blocks shown in FIG. 3 may be implemented as hardware and/or software components that execute specific functions. The functions performed by the blocks shown in FIG. 3 may be implemented by one or more microprocessors or by circuit configurations for the corresponding functions. Some or all of the blocks shown in FIG. 3 may be software modules composed of various programming languages or script languages that run on the processor 110.

First, referring to FIG. 3, the processor 110 of the vehicle door lock release system 100 includes a pattern input unit 111, a smart key confirmation unit 112, a standby mode execution unit 113, and a control unit 114. It can be configured as follows.

The pattern input unit 111 receives and stores the unlock pattern.

The pattern input unit 111 can receive information about the unlock pattern through an AVN mounted on the vehicle or a portable terminal.

Here, the above-described unlock pattern consists of the order and number of times of hitting the tires of the vehicle. For example, it can be input and stored in the form of FL 3, RR 2, FR 1, and RL 1, where FL is the left front Tires, RR refers to the right rear tire, FR refers to the right front tire, and RL refers to the left rear tire.

In addition, the unlock pattern entered in the form of FL 3, RR 2, FR 1, RL 1 first hits the left front tire three times, second hits the right rear tire twice, and thirdly hits the right tire. This means hitting the front tire once, and finally hitting the left rear tire once.

Of course, the order and number of times of hitting the tires can be changed arbitrarily by the driver, and is not limited to the above-described pattern.

Additionally, the pattern input unit 111 may provide a UI (User Interface) for inputting an unlock pattern for an AVN or portable terminal.

For example, the above-described UI first shows selection items representing FL, RL, FR, and RR, and when any one of FL, RL, FR, and RR is selected, it shows an input window where you can enter a number for the selected item. When a number is selected, the unlock pattern can be input by showing the above-mentioned selection item again.

As another example, an image showing the positions of the tires on the vehicle is displayed, an input window is displayed where the driver can enter a number for the selected tire, and when a number is selected, the unlock pattern is displayed again by displaying the image described above. It may also be provided to receive input.

Meanwhile, when the door is unlocked in the second standby mode, which will be described later, the pattern input unit 111 may reset the already stored unlock pattern and re-enter and store a new unlock pattern.

When the vehicle's engine is turned off and the doors are locked, the smart key confirmation unit 112 confirms the location of the smart key based on the smart key detection information input from the SMK ECU 10.

For reference, the SMK ECU 10 described above detects the location of the smart key using a LF (Low Frequency) wireless communication frequency and outputs the corresponding detection information to the smart key confirmation unit 112, which uses this to detect the location of the smart key. The key confirmation unit 112 can check whether the smart key is inside or outside the vehicle.

The standby mode executing unit 113 executes the standby mode according to the result of checking the location of the smart key.

This standby mode executing unit 113 may be provided to execute the first standby mode when the smart key is not inside the vehicle, and to execute the second standby mode when the smart key is inside the vehicle.

Here, the above-described first standby mode is a mode in which the driver of the vehicle gets out of the vehicle while normally holding the smart key and waits for both a signal from the smart key and an input from the tire air pressure sensor 20, and the second standby mode is a mode in which the driver alights while holding the smart key. By leaving the smart key in the vehicle and getting out of the vehicle, unlocking the door using the smart key is not possible and the vehicle may be in a mode waiting only for an input from the tire pressure sensor 20.

That is, the standby mode executing unit 113 enters the first standby mode and waits for the signal from the smart key and the input from the tire air pressure sensor 20, or enters the second standby mode to wait for the input from the tire air pressure sensor 20. will be waiting for.

When an impact is applied to a tire in the first standby mode, the control unit 114 unlocks the door closest to the tire, and when an impact is applied to the tire in the second standby mode, the control unit 114 compares the lock with a pre-stored unlock pattern and then matches it. It performs the function of unlocking the door depending on the presence or absence of the door.

In the first standby mode, the control unit 114 determines the location of the tire on which an impact was applied by the driver based on the pressure detected by the tire air pressure sensor 20, and unlocks the door closest to the tire. The control device 30 can be controlled.

That is, as shown in FIG. 4, when the driver of the vehicle kicks the right rear tire in the first standby mode and impacts it, the pressure detected by the tire air pressure sensor 20 is input to the control unit 114, and the control unit 114 In (114), the right rear door closest to the impacted tire is unlocked, so the driver of the vehicle can easily unlock the desired door without using the smart key or both hands.

At this time, the unlocked right rear door may be provided to open automatically.

However, since someone other than the driver of the vehicle may apply an impact to the tire, it is preferable that the control unit 114 is equipped to unlock the door by confirming that an impact has been applied to the tire by the driver in the first standby mode.

At this time, when the control unit 114 checks the driver, it means checking the vehicle owner. For example, it may be checking whether the driver has the vehicle's smart key or a pre-registered portable terminal.

That is, the location of the smart key is confirmed through the smart key confirmation unit 112 of the control unit 114 to confirm that it is around the tire to which the impact was applied, or the portable terminal matching the pre-registered portable terminal information is confirmed to be in the vicinity of the impacted tire. The door is unlocked by checking what is around the tire.

In addition, in the second standby mode, the control unit 114 can detect an input pattern according to the order and number of times each tire is hit based on the pressure detected by the tire pressure sensor 20, and performs a lock release operation according to the detected input pattern. Compare the patterns and if they match, you can unlock the door.

That is, as shown in FIG. 5, the unlock pattern is stored as FL 3, RR 2, FR 1, and RL 1, and in the second standby mode, three impacts are applied to the left front tire, and the After that, when an input pattern is detected in which 2 impacts are applied to the right rear tire, then 1 impact is applied to the right front tire, and then 1 impact is applied to the left rear tire, the control unit 114 generates the input pattern and Since the unlock pattern matches, the door is unlocked.

As a result, the driver of the vehicle can unlock the door even if he or she does not have the smart key, it is easy to take out the smart key left in the vehicle or take out other luggage, and the driver can leave the child in the vehicle with the smart key and open the door. This can be especially useful in emergency situations where you are locked out.

Meanwhile, the control unit 114 can turn on the emergency lights to notify whether or not the impact applied to the tire is confirmed or whether it matches the unlock pattern. At this time, the control unit 114 communicates with the emergency light control device 40, which turns on and off the emergency lights, to turn on the emergency lights. You can make it light up.

For example, when an impact to a tire is detected, the control unit 114 requests to turn on the emergency lights once, and when the input pattern and the unlock pattern match in the second standby mode, it requests to turn on the emergency lights twice. , If the input pattern and the unlock pattern do not match, the emergency light turns on three times, allowing the driver to be notified whether the input pattern through the tire has been entered correctly.

As such, the present invention can be implemented by the processor 110 executing at least one executable instruction or at least one executable program stored in the memory 130, and the vehicle according to an embodiment of the present invention described later. Likewise, in the case of the door lock unlocking method, it can be implemented by the processor 110 executing at least one executable instruction or at least one executable program stored in the memory 130.

Hereinafter, a method of unlocking a vehicle door lock performed by the vehicle door lock unlocking system 100 according to an embodiment of the present invention will be described.

Figure 6 is a diagram for explaining a method of unlocking a vehicle door lock according to an embodiment of the present invention.

Referring to FIG. 6, the processor 110 of the vehicle door unlock system 100 according to an embodiment of the present invention first receives and stores an unlock pattern consisting of the order and number of hits on the tires of the vehicle. (S110).

In step S110, the processor 110 may receive information about the unlock pattern through the AVN or portable terminal mounted on the vehicle.

Here, the unlock pattern consists of the order and number of times of hitting the vehicle's tires. For example, it can be input and stored in the form of FL 3, RR 2, FR 1, and RL 1, where FL is the left front. Tires, RR refers to the right rear tire, FR refers to the right front tire, and RL refers to the left rear tire.

That is, the unlock pattern entered in the form of FL 3, RR 2, FR 1, RL 1 first hits the left front tire three times (FL 3), and then hits the right rear tire twice (RR 2) After that, it can be released by hitting the right front tire once (FR 1), and then hitting the left rear tire once (RL 1).

As such, the unlock pattern can be changed arbitrarily by the driver, but is not limited to this.

Next, when the vehicle is turned off and the doors are locked (S210), the processor 110 checks whether the smart key is inside or outside the vehicle (S220).

In step S220, the processor 110 may check the location of the smart key based on the smart key detection information input from the SMK ECU 10.

Here, the SMK ECU 10 described above detects the location of the smart key using a LF (Low Frequency) wireless communication frequency and outputs the corresponding detection information to the smart key confirmation unit 112, which uses this to detect the smart key. The confirmation unit 112 can check whether the smart key is inside or outside the vehicle.

Next, if the smart key is not inside the vehicle, the processor 110 enters the first standby mode and waits (S310), and if the smart key is inside the vehicle, the processor 110 enters the second standby mode and waits (S320).

For reference, the first waiting mode in step S310 may be a mode in which the driver of the vehicle normally gets off while holding the smart key and waits for both a signal from the smart key and an input from the tire air pressure sensor 20.

Additionally, the second standby mode of the S320 may be a mode in which the driver leaves the smart key in the vehicle and gets out of the vehicle, making it impossible to unlock the door with the smart key and waiting only for an input from the tire pressure sensor 20.

Next, when entering the first standby mode, the processor 110 detects that an impact has been applied to the tire based on the input of the tire air pressure sensor 20 (S410), turns on the emergency light once to determine whether an impact has been detected. is notified to the driver (S420), and the door closest to the impacted tire is unlocked (S430).

In step S420, the processor 110 may communicate with the emergency light control device 40, which turns on and off the emergency lights, to turn on the emergency lights.

Then, in step S430, the processor 110 determines the location of the tire on which the impact was applied based on the input of the tire air pressure sensor 20, and operates the door control device 30 to unlock the door closest to the tire. takes control.

At this time, the processor 110 unlocks the door by confirming that an impact has been applied to the tire by the driver. Confirming the driver means confirming the vehicle owner, for example, holding the vehicle's smart key. This may be to check whether or not you have a pre-registered portable terminal.

That is, the processor 110 checks the location of the smart key and confirms that it is in the vicinity of the impacted tire, or verifies that a portable terminal matching pre-registered portable terminal information is located in the vicinity of the impacted tire. The door can be unlocked.

In addition, unlocked doors can be opened automatically.

Next, when entering the second standby mode, when a predetermined input pattern is detected based on the input of the tire pressure sensor 20 (S510), the processor 110 turns on the emergency lamp once to determine whether the input pattern is detected. is notified to the driver (S520), and the previously stored unlock pattern is compared with the input pattern (S530).

The input pattern of step S510 refers to a pattern according to the order and number of times each tire is hit. For example, 3 impacts are applied to the left front tire, and then 2 impacts are applied to the right rear tire. This means that one impact was applied to the right front tire, and then one impact was applied to the left rear tire.

Next, if the input pattern and the unlock pattern match, the processor 110 turns on the emergency light twice to notify the driver whether it matches the unlock pattern (S540) and locks the door through the door control device 30. is unlocked (S550), and if the input pattern and the unlock pattern do not match, the door is not unlocked and the emergency lights are turned on three times to indicate that the door does not match the unlock pattern (S560).

In other words, even if the driver does not have a smart key, the door can be unlocked using the unlock pattern, so it is easy to take out the smart key left in the vehicle or take out other luggage, and leave the child in the vehicle with the smart key. This can be especially useful in emergency situations where doors are locked.

Next, when the door is unlocked in the second standby mode, the processor 110 resets the pre-stored unlock pattern and receives and stores a new unlock pattern again (S610).
