The present invention relates to a device for automatically folding and unfolding a side mirror of a vehicle, and more particularly, to an apparatus and method for automatically folding and unfolding a side mirror using a smart key ID of a smart key in a vehicle to which a smart key and a button start method are applied. It is about.

In general, the vehicle is provided with two side mirrors so that the driver can see the vehicle driving in the rear and rear left and right while driving. The side mirror usually projects in front of the top of the front door.

 Currently, parking space is insufficient due to oversupply of vehicles. As a result, drivers often leave their cars on the streets. In addition, there is a trend to minimize the space of one vehicle even if there is a parking space. Accordingly, pedestrians or vehicles often pass by hitting the side of the vehicle parked on the street. In addition, even when parked in a parking space, the parking space is narrow and often passes by touching the side of the vehicle even when the driver passes between vehicles after boarding and getting off the vehicle. In this case, the most hitting part is the side mirror. This caused frequent side mirror failures.

To solve this problem, side mirror folding / unfolding devices that can fold an external side mirror manually or automatically have been developed and applied to a vehicle. In general, the side mirror folding / unfolding device is a button type for folding and unfolding the side mirror by pressing the side mirror folding / unfolding button installed on the driver's side, and automatically unfolding the side mirror when the vehicle is started. And automatic folding of the side mirrors when the ignition is off.

However, in the case of the button type, the driver often gets off the vehicle without pressing the button, and in the case of the automatic type, the side mirror needs to be unfolded even when the ignition is turned off. There was an uncomfortable problem.

Accordingly, an object of the present invention is to determine the smart key ID of the smart key in the vehicle to which the smart key and the button start method is applied and the side mirror automatic folding / unfolding device for folding and unfolding the side mirror by In providing a method.

The driver's seat door module.

Side mirror unfolding method of the present invention for achieving the above object; An authentication process for performing smart key authentication, a side mirror folding state checking process for checking whether the side mirror is in a folding state when the authentication is successful, and a driver boarding determination process for determining whether the driver is on the board if the side mirror is in the folding state. And a side mirror unfolding process of unfolding the side mirror if the driver is on board.

Side mirror folding method of the present invention for achieving the above object; An authentication process for performing smart key authentication, a side mirror unfolding state inspection process for checking an unfolding state of the side mirror when authentication is successful, a driver boarding determination process for determining whether the driver rides when the side mirror is unfolding, and In addition, a smart key authentication out determination process for checking whether smart key authentication out occurs when the driver gets off and a side mirror folding process for folding a side mirror when smart key authentication out occurs.

According to the present invention, since the side mirror is folded or unfolded according to various information such as whether the vehicle is started, as well as whether the smart key authentication information is received and whether the driver is in the vehicle, the folding and unfolding time of the side mirror is more clearly determined. This has the advantage of being able to fold and unfold side mirrors.

The smart key (FOB) holder 7 detects whether the smart key is inserted and informs the power distribution module 30 whether the smart key is inserted.

Driver Door Module (DDM) 10 is also called Door Control Module (DCM), and actuator control of door (not shown), side mirror folding / unfolding control, side mirror position information storage Perform power window control, etc. In addition, the DDM 10 controls the first mirror driver 11 and the second mirror driver 12 according to the input of the side mirror driving signal from the side mirror driving button 13 to fold and unfold the side mirror. In the folding and unfolding of the side mirror, the DDM 10 controls the first mirror driver 11 and the second mirror driver 12 whenever the side mirror driving signal is input from the side mirror driving button 13. By toggling. In other words, if the side mirror is in the folded state, it is unfolded. In addition, the DDM 10 informs the power distribution module 30 of the state of the side mirror, that is, whether the side mirror is in the folded state or the unfolded state, and in response to the side mirror folding / unfolding command input from the power distribution module 30. Accordingly, the side mirror is folded or unfolded by controlling the first mirror driver 11 and the second mirror driver 12.

The power division module (PDM) 30 serves as a power distribution by electronically controlling the main power relay unit 50 in a button start type vehicle, and powers the vehicle through the LED of the start button 6. Identifies the state. In addition, the power distribution module 30 according to the present invention, smart key authentication receiver 40, start detection unit 1, lever position detection unit 2, door state detection unit 3, foot brake state detection unit 4, occupant The state information is input from the detector 5 and the DDM 10, and the side mirror folding / unfolding command is output to the DDM 10 according to the vehicle state information. Specifically, the PDM 30 receives the authentication information from the smart key authentication receiving unit 40 and performs authentication by comparing with the previously stored authentication information, and the authentication result, start-up, gear lever position, foot brake state According to the condition, such as the driver boarding and the side mirror state outputs the side mirror folding / unfolding command to the DDM (10).

The In Panel Module (IPM) 20 performs a vehicle body control function in the same meaning as a Body Control Module (BCM). Since the operation related to the present invention is not performed, detailed description thereof will be omitted.

The smart key authentication receiver 40 includes a radio frequency (RF) receiver 41 and a low frequency (LF) transmitter 42 for smart key 60 authentication, and the LF transmitter 42 And performing wireless data communication with the smart key 60 through the RF receiver 41 to provide the authentication information to the PDM 30 or the DDM 10. The low frequency is 125KHz and the radio frequency is 447MHz.

The DDM 10, the IPM 20, the smart key authentication receiver 40, and the PDM 30 are connected to a control area network (CAN), which is a vehicle control network, to perform data communication according to a CAN protocol.

The power relay unit 50 is connected to a vehicle battery and an alternator and is controlled by the PDM 30 to provide power according to the number of presses of the start button, that is, start, ACC, IGN1, or IGN2 power to the vehicle. .

The smart key 60 is called a fob and stores unique authentication information therein. The smart key 60 is provided with an LF receiver (not shown) and an RF transmitter (not shown) for wireless data communication with the smart key authentication receiver 40, and the LF signal from the smart key authentication receiver 40. When received, the unique authentication information stored in advance is put on the RF signal and transmitted to the smart key authentication receiver 40.

In the above configuration, the configuration in which the PDM 30 receives all status information and controls the automatic folding / unfolding of the side mirror is described. However, the DDM 10 may be configured to receive all state information from the PDM 30 to perform control.

2 is a flowchart illustrating a side mirror unfolding method according to the present invention. Hereinafter, the side mirror unfolding method according to the present invention will be described with reference to FIGS. 1 and 2.

First, when the authentication information of the smart key 60 is received through the smart key authentication receiver 40 in step 211, the PDM 30 compares the authentication information with pre-registered smart key authentication information and determines whether authentication is successful. . In other words, the PDM 30 determines whether authentication information that has been successfully authenticated is received.

If the authentication fails in step 211, the SMK authentication is repeatedly performed within a predetermined time through step 225, and if the smart key 60 authentication fails until the predetermined time is exceeded, proceed to step 227 to apply the side mirror Keep it in state and exit.

On the other hand, if the authentication is successful, the PDM 30 proceeds to step 213 to determine whether the side mirror is in a folded state. In order to know the folding / unfolding state of the side mirror, the PDM 30 has an area for storing the folding / unfolding state of the side mirror, and requests status information from the DDM 10 whenever the side mirror is operated. Stores state information received in response to a request. Alternatively, the DDM 10 may transmit the side mirror status information to the PDM 30 whenever the DDM 10 drives the mirror drivers 11 and 12 without requesting the status information. The side mirror folding state inspection of step 213 is for checking a case in which the driver manually folds the side mirror by the side mirror driving button 13.

As a result of the state inspection of the side mirror, the PDM 30 proceeds to step 215 if the side mirror is in a folded state, and proceeds to step 223 if it is in an unfolded state.

The PDM 30 proceeding to step 223 maintains the side mirror in an unfolded state.

On the other hand, the PDM 30 proceeds to step 215 through the occupant detection unit 5 to check the occupant information, that is, whether the driver boarded.

As a result of the inspection, when the driver is not in the driver's seat, the PDM 30 proceeds to the above-described step 225, and when the driver is in the driver's seat, proceeds to step 217.

In step 217, the PDM 30 checks whether the ALT L signal generated from the start detection unit 1 is high. In other words, the PDM 30 checks whether it is started.

If starting in step 217 does not start, the PDM 30 proceeds to step 225 described above, and if starting starts, proceeds to step 219 to detect the position of the automatic transmission from the lever position detection unit 2, and then the position of the automatic transmission is other than P. Check whether the position is in the position of the automatic transmission, P (parking) release position (R, D, N, etc.).

If the automatic transmission P release does not occur in step 219, the PDM 30 performs step 225 described above. If the automatic transmission P release occurs, the process proceeds to step 221 to unfold the side mirror.

In the side mirror unfolding method, the process of unfolding the side mirror according to three conditions such as whether the driver is riding, whether the vehicle is started and the position of the automatic transmission has been described. However, it is also possible to unfold the side mirror by combining any one or two of the three conditions of the boarding, starting and position of the automatic transmission.

3 is a flowchart illustrating a side mirror folding method according to the present invention. Hereinafter, a side mirror folding method according to the present invention will be described with reference to FIGS. 1 and 3.

First, when the authentication information of the smart key 60 is received through the smart key authentication receiver 40 in step 311, the PDM 30 compares the authentication information with pre-registered smart key authentication information to determine whether authentication is successful. . In other words, the PDM 30 determines whether authentication information that has been successfully authenticated is received.

If the authentication fails in step 311, the SMK authentication is repeatedly performed within a predetermined time through step 327. If the smart key 60 authentication fails until the predetermined time is exceeded, the process proceeds to step 329, where the side mirror is in the current state. Keep and exit.

If the authenticated authentication information is received in step 311, the PDM 30 proceeds to step 313 to check whether the side mirror is in an unfolding state. This is to check the case in which the driver manually operates the side mirror by operating the side mirror driving button 13.

If it is determined in step 313 that the side mirror is in the folded state, the PDM 30 proceeds to step 325 to maintain the side mirror in the folded state and ends the process. On the other hand, if it is determined in step 313 that the side mirror is in an unfolded state, the PDM 30 proceeds to step 315 to check whether the ALT L signal input from the start detection unit 1 is OFF. That is, the PDM 30 checks in step 315 whether the startup is off.

If it is determined in step 315 that the start-up is turned on, the PDM 30 performs step 327 described above. However, if it is determined in step 315 that the startup is turned off, the PDM 30 proceeds to step 317 and checks whether the IGN OFF continues for a predetermined time or more. For example, check whether the IGN OFF duration lasts longer than 5 seconds after starting off.

If the IGN OFF continues for a predetermined time or more, the PDM 30 proceeds to step 319 to check whether the driver has got off via the occupant detector 5.

As a result of the inspection, if the driver is not boarding, the PDM 30 proceeds to step 321 to check whether smart key authentication out (that is, authenticated smart key authentication information) is not received.

When the authenticated smart key authentication information is received in step 321, the PDM 30 returns to the above-described step 327 and performs the above-described steps again, and if the authenticated smart key authentication information is not received (usually "smart key authentication out"). In step 323, the side mirror is folded.

In the side mirror folding method, the process of folding the side mirror according to three conditions such as whether the driver is riding, whether the vehicle is started and the position of the automatic transmission has been described. However, the side mirror may be folded by combining any one or two of the four conditions of the boarding, the IGN OFF duration, whether the vehicle is started and the position of the automatic transmission.

2 and 3 illustrate a method in which the PDM 30 performs side mirror folding / unfolding control according to the present invention. However, the PDM 30 is simply configured to output information input from the start detection unit 1, the lever position detection unit 2, the occupant detection unit 4, etc. to the DDM 10, and the DDM 10 controls all the controls. It can also be configured to.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
