In addition, the automatic folding outside control method according to the present invention in order to achieve the above object, the step of outputting the on / off signal of the DRL according to whether the engine is started; Determining whether the vehicle is in a driving mode or a parking mode according to the output signal, and outputting a control signal corresponding to the determination; Selectively switching and outputting the output control signal; The external mirror may be driven by the output switching signal.

Here, it is preferable to output a drive control signal in which the outside mirror is unfolded in the driving mode, and output a drive control signal in which the outside mirror is folded in the parking mode.

The automatic foldable outside mirror apparatus and control method thereof of the present invention can facilitate vehicle driving by driving the outside mirror of the vehicle to be automatically folded and unfolded using a DRL signal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. no.

1 is a view schematically showing the configuration of an automatic folding outside mirror device according to the present invention. As shown therein, the automatic folding outside mirror device includes: a DRL unit 100 for outputting a lamp on / off signal according to engine start of a vehicle; A controller (110) for determining whether to drive or park according to the output signal of the DRL (100), and output a control signal corresponding to the determination; A relay unit 120 for switching in response to the control signal output from the controller 110; It is configured to include a drive unit 130 for driving the outside mirror by the switching of the relay unit 120.

The Daytime Running Light (DRL) unit 100 allows the headlamp device to always be turned on when the key switch is in the "on" state at startup. Therefore, the start / on signal of the vehicle is input to control the on / off of the headlamp. Here, DRL (Day Time Running Lighting) has adopted a system in some countries in North America and Europe to automatically turn on the headlamp device when the key switch is "on" at start-up.

The controller 110 receives a signal from the DRL unit 100 and outputs a driving control signal for folding and unfolding the outside mirror.

More specifically, the body control module 110 inputs not only the on / off state of the DRL unit 100 but also the start / on state of the vehicle, the on / off state of the head lamp, and the open state signal of the vehicle door. Receive.

The controller 110 determines the parking mode or the driving mode according to the on / off state of the DRL unit 100, the on / off state of the vehicle, the on / off state of the head lamp, and the open state of the vehicle door. Outputs a control signal by folding and unfolding.

At this time, the parking mode determines the driving mode when the DRL is off, the head lamp is off, the start is off, and the door is open, and a control signal for folding the outside mirror is output, and the driving mode is the DRL on and the head lamp. In the ON state and the ON state of the start-up, it is determined as the driving mode and outputs a control signal for extending the outside mirror.

Here, the control unit 110 determines the day mode or the night mode in the parking mode, the DRL is turned off in the daytime mode at the start-off, and determines that the head lamp including the DRL is turned off in the night mode, and outputs a control signal. do.

The relay unit 120 includes a first relay unit 121 that switches to fold the outside mirror and a second relay unit 122 that switches to open the outside mirror. In addition, the battery is connected to a constant power source B + applied from a battery and connected to a contact point and a ground for connecting to the controller.

The first relay unit 121 receives a folding control signal that is determined to be a parking mode from the control unit 110, switches to a contact point for connecting to the control unit, and receives a folding power signal (B +) applied from a battery. To transmit a signal to the driver.

In addition, the second relay unit 122 receives a straightening control signal that is determined by the controller 110 as a driving mode, is switched to a contact point for connecting with the controller, and is always supplied with a constant power source B + applied from the battery. The control signal is transmitted to the driver.

When the signal output from the first relay unit 121 is input, the driver 130 drives the outside mirrors installed on the left and right sides of the vehicle to be folded, and when the signal output from the second relay unit 122 is input. Drive the outside mirrors out.

2 is a flow chart for the automatic folding outside control method according to the present invention. As shown in the figure, the automatic folding outside control method according to the present invention, first outputs the on / off signal of the DRL according to whether the engine is started (S201). That is, the DRL outputs the on / off of the start, the on / off of the head lamp and the open state of the vehicle door corresponding to the on / off state of the engine start of the vehicle.

Then, it is determined whether the driving mode or the parking mode according to the output signal, and outputs a control signal corresponding to the determination (S202).

More specifically, the parking mode determines the driving mode when the DRL is off, the head lamp is off, the start is off, and the door is open, and outputs a control signal for folding the outside mirror, and the driving mode is on the DRL. When the head lamp is turned on and the starting state is turned on, it is determined as a driving mode and a control signal for extending the outside mirror is output.

Here, in the parking mode, the day mode or the night mode is determined. In the start-off mode, the DRL is turned off, and in the night mode, it is determined that the head lamp including the DRL is turned off and the control signal is output.

Then, the output control signal is selectively switched to output (S203). That is, the first relay unit 121 receives the folding control signal that is determined by the controller 110 as the parking mode, is switched to a contact point for connecting with the control unit, and the constant power source B + applied from the battery is input and folded. The control signal is transmitted to the driver.

In addition, the second relay unit 122 receives a straightening control signal that is determined by the control unit 110 as a driving mode, is switched to a contact point for connecting to the control unit, and a constant power source B + is applied from the battery. The spreading control signal is transmitted to the driver.

Subsequently, the outside mirror is driven by the output switching signal (S204). That is, when the signal output from the first relay unit 121 is input, the driver 130 drives the outside mirrors installed on the left and right sides of the vehicle to be folded, and the signal output from the second relay unit 122 is input. Drive the outside mirrors to extend.

As described above, an embodiment of the present invention has been disclosed through the detailed description and the drawings. The terms are used only for the purpose of describing the present invention and are not used to limit the scope of the present invention as defined in the meaning or claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
