Hereinafter, an automatic door locking apparatus according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. 2 is a view for explaining a door automatic locking prevention apparatus according to an embodiment of the present invention, Figure 3 is a view for explaining the door automatic locking prevention operation.

As shown in FIG. 2, the automatic door locking system of the present invention includes a smart key 110, an AVN device 120, and a Bluetooth mobile phone 130.

The smart key 110 transmits an RF signal for unlocking the vehicle door according to a user's manipulation.

The RF receiver 200 receives an RF signal from the smart key 110 and transmits the RF signal to the vehicle controller 300.

When the RF signal for unlocking the vehicle door is transmitted from the RF receiver 200, the vehicle controller 300 unlocks the vehicle door and transmits a start signal to the AVN device 120 to start booting.

If the AVN device 120 includes the head unit 121 as a controller, and the start signal is transmitted from the vehicle control unit 300, the AVN device 120 pre-boots before starting the vehicle. The head unit 121 is paired with the Bluetooth mobile phone 130 carried by the user, and after the pairing is completed, the user can keep the pairing from the vehicle within a radius within which the pairing state is maintained. Location).

If the AVN device 120 remains paired with the user's Bluetooth mobile phone 130 after a predetermined time after the vehicle door is unlocked and before the predetermined time when the user needs to board the vehicle, the AVN device 120 controls the vehicle door by the vehicle control unit 300. The door unlock maintenance signal is transmitted to the vehicle controller 300 to prevent the door from being locked again.

For example, the vehicle controller 300 operates the timer after unlocking the door, and when the count value of the timer reaches a predetermined time, the vehicle controller 300 determines that the user's vehicle ride time has timed out and locks the vehicle door again.

Therefore, the AVN device 120 checks the count value of the timer and prevents the vehicle door from being locked again when the pairing state with the user's Bluetooth mobile phone 130 is maintained before the user's ride time is timed out. The door unlock maintenance signal is transmitted to the vehicle controller 300.

When the door unlocking maintenance signal is transmitted from the AVN device 120, the vehicle controller 300 maintains the unlocked state without re-locking the vehicle door even when the user's vehicle ride time has elapsed.

The timer is initialized when the user boards the vehicle or the door is locked.

Hereinafter, the door automatic locking prevention operation will be described in more detail with reference to FIG. 3.

The AVN device 120 performs an operation to prevent the vehicle door from automatically locking by pre-booting the vehicle according to the unlock signal received from the smart key 110.

In order to carry out the foregoing, the AVN device 120 pairs with the Bluetooth mobile phone 130 carried by the user via the head unit 121, and while the pairing state is maintained after the pairing is completed, the user is disconnected from the vehicle. It is determined that it is located within a pairing maintenance radius (where the vehicle can ride).

For example, when the door unlock signal transmitted from the smart key 110 is transmitted, the vehicle controller 300 transmits a start signal for starting the booting of the AVN 120 device to the AVN device 120.

When the start signal is transmitted, the AVN device 120 pre-boots and transmits the Bluetooth start signal to the head unit 121.

When the Bluetooth start signal is transmitted, the head unit 121 initializes the Bluetooth function, and attempts to pair with the Bluetooth mobile phone 130 carried by the user after the Bluetooth function initialization is completed.

The AVN device 120 checks the count value of the timer operated after the vehicle control unit 300 unlocks the door, and determines that the vehicle door is unlocked when the timer is counting, before the count value reaches a predetermined time. If the pairing state is maintained after the pairing with the Bluetooth mobile phone 130 is completed by the head unit 121, the vehicle control unit determines that the user is located within a radius within which the pairing can be maintained from the vehicle (possible to ride in the vehicle). The door unlock maintenance signal is transmitted to 300.

When the door unlock maintenance signal is transmitted, the vehicle controller 300 maintains the unlocked state without locking the vehicle door even when the timer is timed out.

When the ACC is turned on after the user boards the vehicle, the vehicle controller 300 notifies the AVN device 120 of the ACC ON state, and the ANV device 120 transmits an ACC ON signal to the head unit 121.

When the ACC ON signal is transmitted, the head unit 121 establishes a connection for Bluetooth communication with the Bluetooth mobile phone 130.

As described above, according to the present invention, it is possible to enhance the timeout function of the door locking, to reduce the trouble of unlocking the car door to the user several times, thereby improving the convenience of use, and a separate sensor such as a sensor. The cost can be reduced because it can be implemented by SW alone without the need for additional parts.

In the above, the door automatic locking prevention apparatus according to the exemplary embodiment of the present invention has been described with reference to FIGS. 2 and 3, and the door automatic locking preventing method will be described with reference to FIG. 4 is a flowchart illustrating a door automatic locking prevention method according to an embodiment of the present invention.

As shown in FIG. 4, when an unlock signal for unlocking the vehicle door is received from the smart key (remote control) (S400), the AVN device 120 is pre-booted and carried by the user through the head unit 121. Attempts to pair with the Bluetooth mobile phone 130, and determines whether the pairing is maintained (S401).

As a result of the determination, if the pairing is maintained, a signal is outputted to maintain the unlocked state of the vehicle door (S402), and if the pairing is not maintained, the determination result is a predetermined time of the timer operated after the vehicle door unlocking (approx. 2 Minute) to determine whether it has timed out (S403).

As a result, when the timer has not timed out, a signal is outputted to maintain the unlocked state of the vehicle door (S402). If the timer is timed out, the signal is not outputted so that the unlocked state of the vehicle door is maintained. The door is unlocked (S404).

Although the configuration of the present invention has been described in detail with reference to the preferred embodiments and the accompanying drawings, this is only an example, and various modifications are possible within the scope without departing from the spirit of the present invention.
