It may include.

The operation of the window opening warning device during door locking according to the present invention configured as described above will be described in detail as follows.

First, when a vehicle door locking signal is generated through the smart key controller 10, the vehicle body controller 20 controls to lock the door in conjunction with the door controller 30, and simultaneously requests a window opening/closing state. Here, when the door is locked through a remote control such as the smart key 1, the smart key controller 10 transmits a door locking signal to the vehicle body controller 20.

Upon receiving the door locking signal, the door controller 30 locks all the doors, detects the opening/closing state of the power window, and transmits it to the vehicle body controller 20.

The vehicle body controller 20 interlocks with the door controller 30 to detect the opening/closing state of the power window, and as a result of checking the opening/closing state of the window, if there is an open window, a window closing control command is sent to the door controller 30. Send and request window status information.

The door controller 30 performs a window closing operation according to a control command of the vehicle body controller 20, and then detects a window opening/closing state and transmits it to the vehicle body controller 20.

The vehicle body controller 20 checks the received window opening/closing state information after a window close control command, and if it is a window open signal, determines that the window is closed, generates a window open warning control signal, and generates a buzzer 40 and an emergency light. (60).

The buzzer 40 generates a warning sound according to the window open warning control signal transmitted from the vehicle body controller 20, and generates a warning sound for the window opening to the driver.

In addition, the emergency light 60 is lit or flashing according to the window open warning control signal transmitted from the vehicle body controller 20 to warn the driver about the window opening.

In this way, when a warning sound, an emergency light is on and blinking about the window opening, the driver recognizes this and closes the open window to prevent damage caused by the open window later.

2 is a flow chart showing a window opening warning method when locking a door according to the present invention. (a) When a door closing operation occurs in the vehicle body controller 20, the remote control through the smart key controller 10 to control the fob (FOB) key. Searching steps (S101-S103), (b) Searching for the FOB key at the set search time when the search result of step (a) does not exist in the vehicle but outside the vehicle (S104-S106, S112) -S114, S115-S117), (c) When the search result of step (b) is detected in the vehicle body controller 20, if the forb key is not detected, the door actuator 30 is operated to automatically operate the door actuator. Locking all the doors with (S107-S108), (d) detecting the window opening and closing state by interlocking with the door controller 30 after door locking in the vehicle body controller 20 (S109-S110), ( e) If the window opening state is detected as the result of the step (d), the step S111 of warning the driver of the window opening state is included.

The fob means a vehicle remote control including various functions. Key fobs that only have the function of opening and closing a car door or trunk are key fobs that include a keyless entry function called a smart key these days.

In the step (b), if the set search time is set to 5 seconds or less, the search for the fob key is performed by setting the search for the fob key at a period of 200 m/s, and if the fob key is not detected, the number of times for searching the fob key is set. Retries are attempted as many times as possible, and even if the search for the fob key is retried a set number of times, if the fob key is not detected, it is finally determined that the fob key is not detected (S104-S106). If set, the search for the fob key is set to 500 m/s period, and the search for the fob key is retried as many times as the set number of times. If a fob key is not detected even if an attempt is made, it is finally determined that the fob key is not detected (S112-S114), and when the set search time is set to 10 seconds or more and 30 seconds or less, the fob key search is set to a period of 1,000 m/s. If the forbes key is not detected, and if the forbes key is not detected, the search for the forbes key is retried a set number of times, and even if the search for the forbes key is retried a predetermined number of times, if the forbes key is not detected, the forbes key is finally detected It is determined as undetected (S115-S117).

In step (e), if a door opening warning control signal is generated from the vehicle body controller, a warning sound is generated to the driver according to the window opening, or an emergency light is turned on or flashing to warn the window opening.

When the door opening warning method according to the present invention configured as described above is specifically described as follows.

First, when the locking signals of all the doors are generated as in step S101, the vehicle body controller 20 moves to step S102 to search for a fob key for door control in cooperation with the smart key controller 10. Here, the search time needs to be considered in order to search for the fob key, which is assumed to be set in advance. The search time can be set in the same manner as 5 seconds, 10 seconds, or 30 seconds.

The detection method of the fob key is performed through the LF antenna, and the LF antenna installed outside the vehicle as well as inside the vehicle is also searched for a certified FOB key outside the vehicle. Here, the reason for searching the FOB key using the authentication information is that if there are multiple registered FOB keys, the FOB key is searched based on the last relevant FOB key. That is, the FOB key is searched based on the FOB key recognized first in the authentication. This makes it possible to accurately and automatically control door closing even when multiple FOB keys are registered.

As a result of the search, if the FOB key is found in the vehicle or the FOB key search fails, the door is not automatically closed.

Unlike this, if an authorized FOB key is searched outside the vehicle as in step S103, the process moves to step S104 to check whether the set search time t1 is set to 5 seconds or less. That is, it is checked whether the search time is 5 seconds (5s) or less. If the search time is 5 seconds or less as a result of this check, the flow goes to step S105 to set the fob key search period to 200 m/s period to search for the fob key. As a result of the search for the fob key, if the fob key is not detected as in step S106, the search for the fob key is retried a set number of times (for example, 3 times), and the search for the fob key is retried a set number of times. If the fore key is not detected, it is finally determined that the fore key is not detected.

In addition, it is checked whether the search time t2 set in step S112 is set to 5 seconds or more and 10 seconds or less. That is, it is checked whether the search time exceeds 5 seconds and is 10 seconds or less. As a result of this check, if the search time exceeds 5 seconds and is less than 1 second, the process goes to step S113 to set the fob key search period to 500 m/s period to search for the fob key. Subsequently, if the fore key is not detected in step S114, the search of the fore key is retried a set number of times (for example, 3 times), and the fob key is retried even when the search of the fore key is retried a set number of times. If it is not detected, it is finally determined that the fob key is not detected.

Also, it is checked whether the search time t3 set in step S115 is set to 10 seconds or more and 30 seconds or less. That is, it is checked whether the search time exceeds 10 seconds and is less than 30 seconds. As a result of this check, if the search time is more than 10 seconds and less than 30 seconds, the process moves to step S116 to set the fob key search period to 1,000 m/s period to search for the fob key. Subsequently, if the forb key is not detected in step S117, the search of the forb key is retried a set number of times (for example, 3 times), and the fob key is retried even if the search of the forb key is retried a set number of times. If it is not detected, it is finally determined that the fob key is not detected.

If the forb key is not detected, the vehicle body controller 20 moves to steps S107 and S108 to operate the door actuator in conjunction with the door controller 30 to automatically lock all doors.

Subsequently, the process moves to step S109 to check the door locking state in the vehicle body controller 20, and if the door is locked, the process moves to step S110 to detect a window open state in conjunction with the door controller 30.

As a result of detecting the window state, if the window is open, the process moves to step S111, and the vehicle body controller 20 determines that the window is closed and generates a window open warning control signal to generate a buzzer 40 and an emergency light 60. To be transferred to.

The buzzer 40 generates a warning sound according to the window open warning control signal transmitted from the vehicle body controller 20, and generates a warning sound for the window opening to the driver.

In addition, the emergency light 60 is lit or flashing according to the window open warning control signal transmitted from the vehicle body controller 20 to warn the driver about the window opening.

In this way, when a warning sound, an emergency light is on and blinking about the window opening, the driver recognizes this and closes the open window to prevent damage caused by the open window later.

The invention made by the present inventors has been described in detail according to the above embodiment, but the present invention is not limited to the above embodiment and can be changed in various ways without departing from the gist thereof. It is obvious to those who have it.
