It is noted that " comprises, " or "comprising," as used herein, means the presence or absence of one or more other components, steps, operations, and / Do not exclude the addition.

The present invention controls an electric room mirror inside a vehicle based on map information provided by navigation of a vehicle, steering angle information transmitted from a steering wheel, and speed information of a vehicle sensed by a speed sensor.

Hereinafter, a mirror control apparatus according to an embodiment of the present invention will be described with reference to FIG. 2 is a block diagram for explaining a mirror control apparatus according to an embodiment of the present invention.

2, the mirror control apparatus 100 of the present invention includes a BCM (wired integrated gateway) 110, an electric ECM 120, a power steering 130, a navigation 140, a controller 150, , VDC (Vehicle Dynamic Control) 160, and a speed sensor 170.

The body control unit 110 serves as a wired integrated gateway and transmits the vehicle speed information transmitted through the VDC 160 to the controller 150. The control unit 150 transmits the control signal output from the controller 150 to the electric ECM 120.

The electronic ECM (Electronic Chromic Mirror) 120 performs a function of automatically sensing the light of the rear vehicle entering the room mirror through the optical sensor to reduce the reflectance of the mirror to thereby eliminate the glare of the driver. When the ECM mode is set to ON, it operates in accordance with the control signal transmitted from the BCM 110. When the ECM mode is set to OFF, it operates according to the operation of the driver.

The power steering 130 determines the vehicle traveling direction and transmits the steering angle information to the control unit 150.

Navigation (NAVIGATION) 140 displays the map information on the screen according to the driver's setting and transmits the map information to the controller 150.

The control unit 150 learns the driver's driving habits and driving information based on the map information received from the navigation unit 140 and transmits the received map information, the steering angle information transmitted from the power steering unit 130 and the BCM 110 And outputs a control signal for controlling the electric ECM 120 based on the vehicle speed information.

The VDC (Vehicle Dynamic Control) 160 performs a control operation for improving the vehicle posture and the turning stability, and transmits the vehicle speed information transmitted from the speed sensor 17 to the BCM 110.

The speed sensor 170 is mounted on four wheels to sense the wheel speed and senses the vehicle speed and transmits it to the VDC 160.

Hereinafter, the mirror control apparatus of the present invention will be described in more detail.

The controller 150 determines whether or not the motorized ECM mode is set to ON by the user, and when the motorized ECM mode set by the user is ON, the controller 150 compares the speed information and the running load calculation information (vehicle position change information) And determines whether the result of the comparison is within a predetermined error range.

For example, the control unit 150 receives the vehicle speed sensing value from the speed sensor 170, calculates the driving load based on the GPS information transmitted from the navigation unit 140, calculates the vehicle position change value, Value and the calculated vehicle position change value, and determines whether the resultant value is within a predetermined error range (within approximately 10%).

If it is determined that the comparison result value is within the predetermined error range, the controller 150 determines whether the steering angle information and the road / gradient type operation comparison value are within a predetermined error range.

For example, the control unit 150 receives the steering angle information from the power steering 130, calculates the road / gradient type based on the GPS information and the 3D map information transmitted from the navigation unit 140, / Gradient type operation value and judges whether the result value is within a predetermined error range (approximately 10%).

If the comparison result is within the predetermined error range, the control unit 150 operates the electric ECM 120 according to the driving angle of the predetermined electric motor 120.

That is, the controller 150 checks whether the following three conditions are satisfied, and controls the operation of the electric ECM 120 only when the three conditions are satisfied.

1. When the motorized ECM mode is set to ON by the driver

2. If the result of the comparison between the speed information and the running load calculation value is within the predetermined error range

3. When the result of the comparison between the steering angle information and the road gradient type operation value is within the predetermined error range

If any one of the above three conditions is not satisfied, the controller 150 does not control the operation of the motorized ECM 120. This is to help drivers to drive safely while driving.

When the electric motor ECM mode is set to OFF by the driver, the control unit 150 stops the control operation of the electric ECM 120, so that the electric motor 120 is operated in accordance with the manual operation of the driver.

2, a description has been given of a mirror control apparatus according to an embodiment of the present invention. Hereinafter, an operation method of a mirror control apparatus according to an embodiment of the present invention will be described with reference to FIG. 3 is a flowchart illustrating an operation method of a mirror control apparatus according to an embodiment of the present invention.

As shown in FIG. 3, it is determined whether the motorized ECM mode is set to ON by the user (S300). If the motorized ECM mode set by the user is ON, the speed information and the running load calculation information Position change information) and determines whether the result of the comparison is within a predetermined error range (S301).

For example, the vehicle speed sensing value is received from the speed sensor 170, the vehicle position change value is calculated by calculating the traveling load based on the GPS information transmitted from the navigation 140, and the transmitted vehicle speed sensing value and the calculated vehicle speed And compares the position change value and determines whether the result value is within a predetermined error range (within approximately 10%).

If it is determined that the comparison result value is within the predetermined error range, it is determined whether the comparison value of the steering angle information and the road / gradient type operation is within a predetermined error range (S302).

For example, it receives the steering angle information from the power steering 130, calculates the road / gradient type based on the GPS information and the 3D map information transmitted from the navigation 140, and calculates the road / And determines whether the resultant value is within a predetermined error range (approximately 10%).

As a result of the determination, if the comparison result value is within the predetermined error range, the motorized ECM 120 is operated according to the driving angle of the predetermined motorized ECM 120 as shown in Table 1 (S303).

On the other hand, the driving angle of the electric ECM 120 can be pre-set as shown in Table 1 according to the vehicle speed, that is, the high speed and the low speed.

Vehicle speed \ ECM drive angle        Left / Right Max Angle       Left / right minimum angle Less than 80km (low speed)            10 degrees             0 degrees More than 80km (high speed)             5 degrees             0 degrees

On the other hand, since the vehicle movement varies depending on the steering angle depending on the low speed or the high speed, the left and right maximum angles of the ECM driving angles are set differently according to the vehicle speed in order to reflect the steering angle characteristics.

Hereinafter, the operation method of the mirror control device 100 described above will be supplemented and described.

In the steps S301 and S302 of the present invention, the calculation is performed using the GPS information and the map information. When the calculated value is compared with the specific value and the result is within the predetermined error range (approximately 10%), The reason for configuring the ECM 120 to operate is as follows.

That is, the reason why the GPS and the map information utilization step are configured as the intermediate processing step is to increase the accuracy of the operation of the electric ECM 120. The driver's habits and operation information acquired by the controller 150 may be transmitted to safety and / It is intended to be used as background data when developing next generation controller for convenience.

The reason for not directly controlling the electric ECM 120 based on the map information only is that the GPS signal is not received as in a tunnel or a building because the map information is not updated and may be inconsistent with actual road conditions I can not.

The control unit 150 compares the speed information, the running load calculation information comparison / steering angle information, and the road gradient type calculation information, and sets the electric ECM 120 to operate only when the result is in the error range. This is because, when the electric ECM 120 is operated, it may cause discomfort to the driver.

That is, configuring the electric ECM 120 to operate within an error range can prevent the driver from misunderstanding that the electric ECM 120 is malfunctioning, and can help the driver to drive safely.

On the other hand, in the present invention, when the electric ECM mode is set to ON, based on the map information transmitted from the navigation mounted on the vehicle, the steering angle information transmitted from the power steering of the vehicle, and the vehicle speed information transmitted from the vehicle speed sensor, The present invention is not limited to this, and a motorized side mirror mode may be additionally provided as a separate operation mode. When the motorized side mirror mode is set to ON, map information of navigation, steering angle information of power steering, It is possible to configure the side mirrors to be controlled based on the speed information of the side mirrors.
