Hereinafter, the , the exemplary embodiments of the present invention is described with reference to the accompanying drawings.
The side mirror 120 provides the driver with a view of the rear of the vehicle.

The side mirrors may include actuators for folding and unfolding operations. Wherein the actuator may include a motor.
The side mirror 120 includes a housing 121 forming an external appearance and a mirror member 122 provided inside the housing 121 so that the reflection surface is exposed to the outside.
The side mirror 120 maintains the unfolded state during traveling. At the instant time, the housing 121 may have curved form to minimize the resistance of the wind acting on the side mirror 120. That is, the housing 121 may have a shape gradually narrower toward the rear of the mirror member 122 with respect to the position of the mirror member 122.
The mirror member 122 of the side mirror 120 may be provided inside the housing 121 so that the reflecting surface reflecting the shape of the object behind the vehicle is exposed to the outside.
This mirror member 122 may rotate on the first axis and the second axis. The first axis may be the X-axis on the two-dimensional coordinate, and the second axis may be the Y-axis on the two-dimensional coordinate. The first axis may be perpendicular to the second axis.
The mirror member 122 may move in the X-axis and move in the Y-axis.
The movement distance when the mirror member 122 moves along the X-axis is referred to as a tilt angle of the first axis and the movement distance when the mirror member 122 is moved along the Y-axis is referred to as a pan angle of the second axis.

At the instant time, the mirror member 122 automatically moves from the current position to the target position. Wherein movement of the mirror member may be rotation of the mirror member to the first axis and second axis.
With respect to the movement of the mirror member, the movement distance (i.e., corresponding to the tilt angle) when rotating by the first axis may be represented by the X-axis coordinate, and the movement distance when rotating by the second axis (i.e., corresponding to the pan angle) may be represented by Y-axis coordinates.
At the present time, the position of the coordinate point corresponding to the current tilt angle and pan angle may be the current position, and the position of the coordinate point corresponding to the tilt angle and pan angle set by the driver may be the target position.

The driving apparatus of the side mirror identifies the first movement distance and the second movement distance, and selects the path having the shortest movement distance among the identified movement distances as the movement path of the mirror member.
In other words, the driving apparatus of the side mirror selects a path near the center position from the two paths as the movement path of the mirror member. This is because the greater the movement from the center to the external side of the mirror member, the more mechanical interference between the housing and the mirror member occurs.

For example, when the coordinate values of the first switching position are 3, 3 and the coordinate values of the second switching position are 5, 5, the driving apparatus of the side mirror acquires the first straight distance D1 to 32+32=18, the second straight distance D2 to 52+52=50.
The driving apparatus of the side mirror identifies the first straight distance and the second straight distance and selects the path having the shortest straight line distance among the identified straight distances as the movement path of the mirror member.
In other words, the driving apparatus of the side mirror may select the path having the shortest distance between the switching position and the center position among the plurality of paths.
The driving apparatus of the side mirror controls the movement of the mirror member based on the information related to the selected path.
In other words, the driving apparatus of the side mirror moves the mirror member along the X-axis through operation of the first driving unit so that the mirror member moves from the current position to the first switching position, and when the moved position is the first switching position, moves the mirror member from the first switching position to the target position by moving the mirror member in the Y-axis through operation of the second driving unit after the operation of the first driving unit is stopped
Moving the mirror member along the X-axis may include tilt rotation of the mirror member about the first axis.
Moving the mirror member in the Y-axis may also include pan rotation of the mirror member about the second axis.
When the current position of the mirror member is determined to be the target position 206 during the movement of the mirror member, the driving apparatus of the side mirror stops the movement of the mirror member. Furthermore, the driving apparatus of the side mirror may display through the display or output sound through the sound output unit that the angle adjustment of the mirror member is completed.
That is,
The driving apparatus of the side mirrors moves the mirror member to the target position 211, determines whether stop is occurred 212, if it is determined that the stop is not occurred, maintains the movement of the mirror member, if it is determined that the stop is occurred, counts the stop time from the stop time 213.
Determining whether the stop is occurred includes determining that the position on the two-dimensional coordinate during the operation of the first driving unit or the second driving unit is the same.
The driving apparatus of the side mirror compares the counted stop time with the reference time, maintains the movement of the mirror member when it is determined that the counted stop time is less than the reference time, and performs an avoidance movement 215 when it is determined that the counted stop time is longer than the reference time 214.
Performing the avoidance movement includes identifying the movement direction and moving by a reference distance in a direction opposite to the identified direction thereof, i.e., in a perpendicular direction thereof.
Moving by a reference distance may include moving during a reference movement time.
Furthermore, when moving by a reference distance in the perpendicular direction thereof, the driving apparatus of the side mirror moves the mirror member in the direction close to the center position.
In other words, performing the avoidance movement may include identifying the driving unit which is being driven and the non-driving unit, operating the identified non-driving unit during the reference movement time, and deactivating the identified driving unit at the same time.
In other words, performing the avoidance movement may include identifying the rotating axis and the non-rotating axis, stopping the identified rotating axis, and rotating the non-rotating axis for the reference movement time.

When the mirror member of the side mirror moves to the right from the third point TP3 to the fourth point TP4, if it is determined that the mirror member is stopped in the third quadrant 143 due to mechanical interference, the mirror member is moved upward toward the center position CP by the reference distance, also, if it is determined that the mirror member is stopped in the fourth quadrant 144 due to mechanical interference, the mirror member is moved upward toward the center position CP by the reference distance.
When the mirror member of the side mirror moves upwards from the fourth point TP4 to the first point TP1, if it is determined that the mirror member is stopped in the fourth quadrant 144 due to mechanical interference, the mirror member is moved to the left toward the center position CP by the reference distance, also, If it is determined that the mirror member is stopped in the first quadrant 141 due to mechanical interference, the mirror member is moved to the left toward the center position CP by the reference distance.
