Apparatus and method for supporting securing of rear view using side mirror}

The present invention relates to an apparatus and method for assisting rear view security at night or in reverse. More particularly, the present invention relates to an apparatus and a method for assisting rear view security using a side mirror.

Side mirrors, which are installed in most vehicles, help the driver to have sufficient visibility while driving. These side mirrors can be adjusted either electronically or manually to help ensure visibility even with various driver body changes.

There are also products with built-in hot wires to prevent moisture from forming on the mirror surface in winter. Such side mirrors allow the driver to easily grasp the access of the left and right vehicles while looking at the front while driving, and can easily identify left and right obstacles and lanes when parking to help the convenience of parking.

However, side mirrors have blind spots or dead angle areas due to the limitation of the viewing angle. In addition, the side mirrors do not perform well when the field of view is dark due to the limitations of the optics.

To solve this problem, many drivers are equipped with a convex mirror or a blind spot detection device using ultrasonic waves or RF.

These products can certainly reduce blind spots while driving. However, the Blind Spot Detection device can detect the approach of moving objects such as driving vehicles, but cannot distinguish between stationary objects such as lanes, and the convex mirror has the effect of securing the viewing angle, but the side mirror has The disadvantage is that the watch does not provide good visibility in the dark state.

Preferably, the comparing unit calculates the illuminance using the sensed light amount and compares the calculated illuminance with the reference illuminance, and the lamp driving unit drives the lamp when the calculated illuminance is equal to or less than the reference illuminance.

Preferably, the visibility securing apparatus is driven when the light output from the lighting device of the other vehicle is sensed or the gear of the vehicle is the reverse gear.

The present invention also provides a light quantity sensing step of sensing the amount of light flowing into the vehicle through the side mirror; A comparison step of comparing the detected light quantity with the reference light quantity, or calculating illuminance using the detected light quantity and comparing the calculated illuminance with the reference illuminance; And a lamp driving step of driving a lamp mounted to the rear of the vehicle in the side mirror when the sensed light amount is below the reference light amount or the calculated illuminance is below the reference illuminance. We propose a visual aiding method using.

Blind Spot Detection products or convex mirrors, which are conventionally used to compensate for the shortcomings of the viewing angles of side mirrors, have their own limitations, which potentially includes the following problems.

In the case of sunting, which is recognized as a basic option when the vehicle is shipped, products with a transmittance far lower than the legal transmittance are frequently applied. In the case of such a vehicle, when parking a vehicle in an underground parking lot with low light at night, the visibility is not properly secured, and it is often inconvenient for parking. Although the vehicle equipped with a rear camera can eliminate some inconvenience. For other vehicles, it is a hassle to open the driver's window and check the outside features from time to time.

In this case, the blind spot detection system or the convex mirror does not solve the disadvantage of inadvertently indicating the lanes in the parking lot. Therefore, it is necessary to propose another system to increase the convenience of parking in the rain or low light at night.

When it is determined that the amount of light sensed by the comparing unit 120 is less than or equal to the reference light amount, the lamp driver 130 drives the lamp mounted to face the rear of the vehicle in the side mirror.

In addition, the lamp driver 130 performs a function of driving the lamp when it is determined that the illuminance calculated by the comparator 120 is less than or equal to the reference altitude.

Lamps mounted on the side mirrors are preferably waterproofed in consideration of being exposed to the outside of the vehicle and mounted on the outside of the mirrors of the side mirrors.

Convex mirrors used to overcome the limitations of side mirror viewing angles, or in the BSD case, require a separate solution for parking in a heavily lit underground parking lot or in dark nights. In the present invention, by applying the basic principle of the ECM room mirror and makeup mirror that is conventionally applied in the vehicle interior to the side mirror, whether in a dark or a car that is not suntight, it improves the convenience when parking in the dark Suggest a device that can give. Hereinafter, an embodiment thereof will be described.

2 is a block diagram schematically illustrating a side mirror view assisting system according to an embodiment of the present invention. FIG. 3 is a reference diagram for describing a driving process of the apparatus 1 shown in FIG. 2. 4 is an exemplary view illustrating an example of mounting a lamp mounted on a side mirror.

The configuration of the system 200 proposed in the present invention is as follows.

First, the device 1 (210) for detecting the light transmitted through the room through the glass window that the exterior environment of the vehicle reflected on the side mirror, the device 2 (220) that can illuminate the side mirror, and the control unit device 3 230.

To do this, first look at the principle used in the ECM room mirror, ECM (photosensitive room mirror) is to detect the light entering the room mirror by the headlights of the rear vehicle with a sensor to automatically reduce the reflectance of the mirror to remove the glare of the driver Device.

That is, the device 1 210 is configured by using a principle of controlling the reflectance of the glass through the sensor 211 which senses the amount of light transmitted from the rear window to enter the side mirror. The photosensitive sensor 211 is mounted at the positions 310 and 320 shown in FIG. 3A to sense how bright the light coming from the side mirror enters the driver.

However, since the sensor cannot be mounted on the driver's eyes, the photosensitive sensor 211 is mounted on the roof side of the vehicle, and the error range is tilted by reflecting the driver's side mirror up / down / left / right angle adjustment degree. Actively coordinate with device 212.

In addition, adjusting the offset of the amount of photosensing is shown in FIG. In the present invention, the photosensitive sensor offset is adjusted according to the angle adjustment amount using the button 330 shown in FIG. This makes it possible to determine the amount of light transmitted from the side mirror 340 in the 350 position even in the case of the selected vehicle.

3 (a) and (b) through the configuration shown in Figure 3 (c) when detecting the light reflected from the side mirror during parking, the amount of light detected is less in the case of a vehicle with a high turning degree of the vehicle For example, when the vehicle is not deeply selected, the amount of light transmitted and detected is increased. Based on this, the device 2 220 capable of securing the driver's field of view in the side mirror is driven.

The principle of operation of device 2 220 is as follows.

Looking at the small mirrors on the front passenger sun visors of the car, it helps the driver look a little brighter by giving the lamp the right amount of light on the mirror. Lighting mirrors, such as those used in dressing rooms, use a similar principle to provide a brighter screen.

In this embodiment, the lamp is mounted on the housing part of the side mirror by using this, so that the driver can see the image actually seen brightly. That is, when the angle of the side mirror is adjusted according to the input of the gear signal 240 and the angle of the side mirror is detected by the device 2 220 (222), the controller 231 of the device 3 230 is the device 2 Lateral rear lighting is performed using the LED lighting control device 221 of 220.

In the present invention, as shown in FIG.

In addition, as shown in FIG. 4 (b), the mounting position of the LED lamp is recessed and mounted inside the side mirror cover housing 450 (460, 470) so that the lamp may be damaged or abnormal operation due to rain, fog or snow. Waterproof not to be.

As described above, even when the vehicle is darkly set up using the system, the outside of the vehicle can be easily identified, and thus the rear view can be easily secured when parking in a dark night or a low-light parking lot.

The reason why the photosensitive sensor is not installed in the mirror like the ECM and is installed inside the vehicle is to accurately determine the amount of light emitted from the outside since the deviation of the amount of light reaching the actual driver may vary depending on the degree of turning of the vehicle. .

In addition, since the indoor light may be attempted to park, the apparatus 1 211 monitors the lighting state of the indoor light of the vehicle and reflects it in the light quantity calculation.

The operation sequence of the present invention is as follows. FIG. 5 is a flowchart sequentially illustrating a sequence of operations of the side mirror view securing assistance system according to an embodiment of the present invention.

First, when the position of the gear is detected to be R (reverse), the operation of the apparatus 1 starts (S505).

When the driver adjusts the position of the side mirror by attaching a sensor for detecting the angle of the side mirror of the driver's seat and the passenger's seat, the moving angle is sensed (S510, S515) to adjust the angle of the photosensitive sensor (S520), and external light This is reflected by the side mirror and the photosensitive sensor recognizes it (S525), the input value is changed according to the ambient light and the turning state of the vehicle.

When the recognized illuminance falls below the threshold (S530), the device 2 starts to operate.

Since the watch is dark enough that the driver cannot park using the side mirror, the LED light attached to the side mirror is irradiated toward the rear of the vehicle (S535, S540). Side and rear view can be observed.

In addition, the LED lighting is designed to adjust the brightness, it is possible to prevent the case that the field of vision can not be properly confirmed by increasing the illuminance of the rear and rear unnecessarily.

The irradiation of the LED light on the rear of the vehicle is terminated when the parking signal is detected (S545) (S550).

Next, a brief description will be given of a driving method of the visual field securing assistance device 100 of FIG. 1.

First, the angle adjusting unit 140 adjusts the angle of the side mirror (angle adjusting step).

Then, the offset adjusting unit 150 adjusts the offset of the sensor for detecting the amount of light flowing into the vehicle based on the angle adjusted by the angle adjusting unit 140 (offset adjusting step).

Thereafter, the light amount detecting unit 110 detects the amount of light flowing into the vehicle through the side mirror (light amount detecting step).

Thereafter, the comparator 120 compares the amount of light detected by the light amount detecting unit 110 with the reference light amount, or calculates the illuminance using the detected light amount and compares the calculated illuminance with the reference illuminance (comparison step).

Thereafter, the lamp driver 130 drives the lamp mounted to face the rear of the vehicle in the side mirror when the detected light amount is equal to or less than the reference light amount or the calculated illuminance is equal to or less than the reference illuminance (lamp driving step).

The light quantity sensing step, the comparing step and the lamp driving step are performed when the light output from the lighting device of the other vehicle is detected or the gear of the own vehicle is the reverse gear.
