DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for automatically controlling a door of a vehicle using a paw key according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a door control system of a vehicle to which a door automatic control method of a vehicle using a paw key according to a preferred embodiment of the present invention is applied.

The door control system of a vehicle to which the present invention is applied includes a power supply unit 10 for supplying power, a door operation unit 20 for manually opening and closing the door, an FOB sensing unit 30 for sensing a FOB key, A time setting unit 50 for setting a pod key search time, and a door driving unit 60 for opening or closing the door 70 .

The fob means the decoration carried with the original key, which also means a car remote control with such a function. It does not mean smart keys that are popular these days. All car remote controls with multiple functions are Key Fob. Key fobs that only have the ability to open and close car doors or trunks, Keyless Entry / Keyless Enging Start, now called Smart Keys, are all Key Fobs. BMW is called Comfort Access, Audi is called Advanced Key and so on. The names are different, but they all have the same function.

FIG. 2 is a flowchart illustrating a method of automatically controlling a door of a vehicle using the Pawkey according to the present invention, wherein S represents a step.

As shown in FIG. 2, the method of automatically controlling a door of a vehicle using the Paw key according to the present invention includes the steps of: (a) searching for a FOB key (S101 to S102) upon occurrence of a door closing operation; (b) searching the FOB key at a set search time (S103 to S103, S110 to S113, S114 to S117) when the search result Pod key is not present in the vehicle but exists outside the vehicle; (c) a step (S108 ~ S109) of automatically locking all the doors by operating the door actuator when the pod key is detected as a result of the search in the step (b).

Wherein, if the set search time is set to 5 seconds or less, the step (b) searches the Pod key by setting the Pod key search at a cycle of 200m / s, and if the Pod key is not detected, , And if the Pov key is not detected even if the Pov key is retried a predetermined number of times, it is finally determined that the Pov key is not detected.

If the set search time is set to more than 5 seconds and less than 10 seconds, the search of the pod key is performed by setting the search time of the pod to 500 m / s, and if the search is not detected, If the Pobu key is not detected even if the Pebb key is retried by the set number of times, it is determined that the Pebb key is not detected yet.

If the set search time is set to 10 seconds or more and 30 seconds or less, the search for the pod keys is performed by setting the search time of the pod keys to 1,000 m / s, and if the pod keys are not detected, The search is retried by the set number of times, and if the Pov key is not detected even if the Pov key is retried by the set number of times, it is finally determined that the Pov key is not detected.

A method of automatically controlling a door of a vehicle using the paw key according to a preferred embodiment of the present invention will now be described in detail.

First, the vehicle control apparatus 40 operates with the power supplied from the power supply unit 10, searches for the door operating unit 20, the starting state, and the like, and if the condition is such that the door should be closed automatically, The door is automatically controlled through the process.

Here, the search time of the fork key must be considered for the door control, which can be freely set by the user through the time setting unit 50 in advance. For example, you can set the seek time in such a way as 10 seconds, 20 seconds, 30 seconds, 1 minute, and so on.

For example, the routine enters a routine for automatically closing the door as in step S101, and detects the FOB key in step S102. The detection of the forbey key is performed through the LF antenna. The detection of the presence of the authenticated FOB key outside the vehicle is performed through the LF antenna installed inside the vehicle as well as outside the vehicle. Here, the reason why the FOB key is searched for using the authentication information is to search for the FOB key based on the Last relevant FOB key when there are a plurality of registered FOB keys. That is, the FOB key is searched based on the FOB key recognized first in the authentication. Thus, even when a plurality of FOB keys are registered, it is possible to accurately and accurately control the door closing.

If the FOB key is searched in the search result vehicle or the FOB key search fails, the door is not automatically closed. Otherwise, if an FOB key that is authenticated outside the vehicle is searched in step S103, the process proceeds to step S104 to check whether the set search time t1 is set to 5 seconds or less. That is, it is confirmed whether the search time is 5 seconds (5s) or less. If it is determined that the search time is less than 5 seconds, the process proceeds to step S105, and the pod key search period is set to 200 m / s to search for the pod key. If the Pobe key is not detected as in the search result step S106 of the Pobe key, the process goes to step S107 to retry the search of the Pobe key by a set number (for example, three times) If the Paw key is not detected even after the number of times of retry, the Paw key is determined to be finally detected.

It is checked whether the search time t2 set as in step S110 is set to more than 5 seconds and less than 10 seconds. That is, it is confirmed whether the search time is more than 5 seconds and less than 10 seconds. If the search time is more than 5 seconds and less than 1 second as a result of the check, the process proceeds to step S111, where the Pobey key search cycle is set to 500m / s to search for the Pobkey key. Thereafter, if it is determined in step S112 that the Pod key is not detected, the process proceeds to step S113 to retry the search of the Pod key by a preset number of times (for example, three times) Even if the Paw key is not detected, it is determined that the Paw key is not detected.

Also, it is confirmed whether the search time t3 set as in step S114 is set to 10 seconds or more and 30 seconds or less. That is, it is confirmed whether the search time exceeds 10 seconds and is 30 seconds or less. If it is determined that the search time is more than 10 seconds and less than 30 seconds, the procedure goes to step S115, and the pod key search period is set to 1,000 m / s to search for the pod key. Thereafter, if it is determined in step S116 that the Pod key is not detected, the process proceeds to step S117 to retry the search of the Pod key by a preset number of times (for example, three times) Even if the Paw key is not detected, it is determined that the Paw key is not detected.

Also, if the full search time (T (30s) = t1 (5s) + t2 (5s) + t3 (20s)) has elapsed but the fork key is not searched, it is finally processed as if the forb key is not detected.

If the Pawkey is not detected at all, the process proceeds to step S108 where the door driver (actuator) 60 is automatically operated to lock the door 70. That is, if the Pawkey is not detected, all doors are automatically locked.
