Description

[0001] Apparatus and method for controlling lamp brightness of a vehicle [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for controlling lamp brightness of a vehicle, and more particularly, to an apparatus and method for controlling lamp brightness of a vehicle capable of controlling lamp brightness of a vehicle according to weather conditions.

Generally, a vehicle has a lamp having a lighting function for easily confirming an object located in the vicinity of the vehicle at nighttime, and a signal function for notifying other vehicle or road users of the running state of the vehicle.

For example, head lamps and fog lamps are intended for illumination purposes, and turn signal lamps, tail lamps, brake lamps, and side markers are signals.

The problem often encountered during vehicle operation is that the condition of the lamp should be adjusted according to the change of the weather, For example, when the head lamp is turned on at dawn, it is necessary to turn off the headlight when it becomes bright in the morning. However, the driver may continue to operate the headlamp without lighting the head lamp. A similar situation is that fog lamps or tail lamps must be turned on in foggy weather, rain, or snowy weather, but they are not aware of this and risk a car accident.

That is, drivers know that certain lamps should be lighted in certain weather conditions, but they can not cope with the changing weather conditions from time to time, and thus can suffer unintentional vehicle accidents.

Recently, there has been proposed a method of automatically turning on the lamp even if the driver does not recognize it in the ever-changing weather conditions. In this case, however, the lamp is turned on just like a bad weather condition because it is merely lighting a specific lamp with a predetermined brightness There is still a risk of a car accident in a weather situation where the surrounding vehicles are difficult to identify.

Accordingly, there is a need for a method of controlling the brightness of a lamp according to weather conditions so as to ensure sufficient visibility of surrounding vehicles, in addition to lighting the lamp according to the weather conditions that change from time to time.

Hereinafter, the present invention will be described with reference to the drawings for explaining an apparatus and method for controlling lamp brightness of a vehicle according to embodiments of the present invention.

1 is a block diagram showing a lamp brightness control apparatus for a vehicle according to an embodiment of the present invention.

As shown in the figure, the lamp brightness control apparatus 1 of the vehicle according to the embodiment of the present invention includes a weather information receiving unit 100 for receiving weather information of an area where a vehicle is located, a weather And a brightness control unit 300 for controlling the brightness of the lamp 400 based on at least one of the received weather information and the sensed weather conditions.

The lamp 400 to be subjected to brightness control in the embodiment of the present invention may include a head lamp, a tail lamp, a fog lamp, a turn signal lamp, a brake lamp, a backup lamp, etc., Type lamps may be included.

The weather information receiving unit 100 can receive weather information through wired or wireless communication. For example, the weather information receiving unit 100 can receive weather information by being installed in a navigation system installed in a vehicle or a DMB (Digital Multimedia Broadcasting) receiving apparatus.

In the embodiment of the present invention, the weather information receiving unit 100 is provided in the navigation system and receives weather information. However, this is for easily determining the area where the vehicle is located, A GPS (Global Positioning System) device may be provided in the DMB receiving apparatus or a separate receiving apparatus as well as the navigation apparatus.

Also, even when a separate GPS device is not provided, the received weather information may be displayed on the screen of the navigation device or the DMB receiving device so that the driver may select the weather information of the area where the vehicle is located.

The weather information receiving unit 100 receives weather information corresponding to an area where the current vehicle is located among the weather information provided from the weather information provider (for example, weather station) by selecting the position of the vehicle or the operation of the driver, The location information may be transmitted to the weather information provider and the weather information according to the transmitted location information may be received.

The weather information receiving unit 100 can receive updated weather information at predetermined time intervals and store the received weather information in a storage medium provided in the vehicle. As a storage medium for storing received weather information, a hard disk, a flash memory, a Compact Flash card, an SD card (Secure Digital Card), an SM card (Smart Media Card), an MMC (Multimedia Card) A memory stick, and the like, may be provided in the weather information receiving unit 100 or may be provided in a separate device. In the case where the storage medium is provided in a separate device, (100) can perform communication with a separate apparatus.

The weather condition detecting unit 200 may detect a weather condition of a vehicle installed in the vehicle and may detect a weather condition of the vehicle. In the present embodiment, the weather condition detecting unit 200 may include a temperature sensor 210, 220, a propriety detection sensor 230, and a wiper operation speed detection sensor 240. The type and number of sensors to be used are variously changed according to weather conditions to be sensed .

The brightness controller 300 may control the brightness of the lamp 400 based on at least one of the weather information received through the weather information receiver 100 and the weather detected by the weather detector 200. [ In the exemplary embodiment of the present invention, the brightness controller 300 controls the brightness of the lamp 400 in consideration of the received weather information and the detected weather conditions. However, the present invention is not limited thereto, The brightness of the lamp 400 may be controlled in consideration of either the weather information or the detected weather condition. Controlling the brightness of the lamp 400 in an embodiment of the present invention may include not only increasing or decreasing the brightness of the lamp 400, but also turning the lamp 400 on or off.

As described above, in the embodiment of the present invention, when the brightness controller 300 controls the brightness of the lamp 400 based on at least one of the received weather information and the sensed weather conditions, It is possible to improve the accuracy of the weather as compared with the case where the brightness of the lamp 400 is controlled based on only one of the weather conditions.

The brightness controller 300 can determine the current weather condition based on the received weather information and the sensed weather conditions. An example of the weather conditions that the brightness controller 300 determines is shown in FIG.

2, when the weather information received through the weather information receiving unit 100 is fine or cloudy, the brightness controller 300 can determine the weather condition to be normal regardless of the detected weather condition, If the weather information is rain or snow and the wiper operating speed detected by the wiper operating speed sensor 240 is N or more, it can be determined that the weather condition is rainy. If the received weather information is foggy and the humidity sensor 220) is M% or more, it can be determined as a fog condition.

In this case, in FIG. 2, the wiper operating speed is N, which means that the wiper operating at various stages according to the operating speed usually corresponds to the speed at which the wiper operates, and the humidity is M% And the wiper operating speed and humidity, which are the standard for judging the weather condition, can be variously changed according to the area, the road, and the like.

In this way, in the embodiment of the present invention, the brightness controller 300 not only receives the weather information received through the weather information receiver 100, but also various sensors 210, 220, 230, and 240 included in the weather condition sensor 200, And the brightness of the lamp 400 can be controlled according to the determined weather condition. Accordingly, it is possible to determine a more accurate weather condition, Brightness control becomes possible.

Referring again to FIG. 2, when the weather condition is determined to be normal, the brightness controller 300 does not control the brightness of the lamp 400 independently of the detected weather condition, and when it is determined that the weather condition is rainy The brightness of the lamp 400 is increased by the target brightness set for the rainfall situation. If it is determined that the weather condition is a fog situation, the fog lamp is turned on if the fog lamp is off, and the target brightness The brightness of the lamp 400 is increased.

2, weather conditions, weather information, and weather conditions may be further subdivided, and the target brightness of the lamp 400 may be variously varied Can be set.

Meanwhile, in the above-described FIG. 2, the case where the received weather information and the sensed weather conditions all correspond to the specific weather conditions are exemplified, but this is merely an example for facilitating understanding of the present invention, The received weather information and the detected weather conditions may indicate different weather conditions.

In the embodiment of the present invention, when the received weather information and the detected weather conditions indicate different weather conditions, the brightness can be controlled based on a weather situation having a high priority according to a predetermined priority.

For example, if the received weather information has a higher priority than the sensed weather condition, the received weather information is clear or cloudy, while if the sensed weather condition is greater than or equal to the humidity M% In this case, the brightness controller 300 determines the brightness of the lamp 400 based on the weather condition according to the received weather information having a high priority. In this case, According to the embodiment of the present invention, the brightness control unit 300 does not separately control the brightness when the weather condition is normal. Therefore, even when the weather condition indicates a fog situation, It is not controlled. Of course, in the embodiment of the present invention, the received weather information has a higher priority than the detected weather condition. However, the present invention is not limited to this, and the priority order can be changed variously.

The brightness controller 300 may previously store the target brightness of the lamp 400 in a specific weather condition and may control the brightness of the lamp 400 to be the target brightness according to the current weather condition have.

The brightness control unit 300 may separately store the target brightness in the specific weather condition for each lamp 400 installed in the vehicle and may control the brightness so that each lamp 400 becomes the target brightness. In other words, in the embodiment of the present invention, the lamp 400 requiring brightness control can be determined according to the weather conditions, and the brightness controller 300 sets the brightness of the lamp 400, which requires brightness control, It is possible to control according to the brightness.

For example, when the weather condition is determined to be rainy, the brightness controller 300 increases the brightness of the lamp 400 from the current brightness to the target brightness according to the rainy conditions. The brightness controller 300 may control the brightness to gradually change from the current brightness to the target brightness until the brightness of the surrounding vehicle is constant.

3, there is a time delay T 1 -T 0 between the time T 0 at which the brightness of the lamp 400 is changed by the brightness controller 300 and the time T 1 at which the target brightness becomes the target brightness To change gradually. In FIG. 3, the brightness of the lamp 400 varies linearly. However, the brightness of the lamp 400 may vary in various forms.

For example, in the case of a rear combination lamp, a tail lamp and a brake lamp function can be performed together with a single lamp. If the tail lamp is turned on and the brightness is temporarily increased according to the weather conditions, The brightness of the vehicle is gradually increased so that it is difficult for the driver of the surrounding vehicle to perceive it because the brake lamp is turned on.

In the embodiment of the present invention, the brightness controller 300 will exemplify a case where an IIR (Infinite Impulse Response) filter is used to set a time delay for changing the brightness of a lamp. (1) < / RTI >

[Equation 1]

y [k] = b 0 · x [k] + a 1 · y [k-1]

At this time, in the Formula 1 y [k] denotes the brightness of the present time, x [k] represents the target brightness, y [k-1] represents the brightness of the earlier time, b 0 And a 1 are constants, which may have values of 0.1 and 0.9, respectively, and the previous time and the present time may have a certain time interval.

As described above, in the embodiment of the present invention, the brightness of the previous time is fed back and the brightness can be controlled so that the brightness of the present time becomes the target brightness. By repeating this process, the brightness gradually increases from the current brightness to the target brightness So that it is difficult for the driver of the surrounding vehicle to perceive the change in the brightness of the lamp 400, thereby preventing the driver of the surrounding vehicle from being confused if the brightness of the lamp 400 changes at a certain time.

The brightness control unit 300 may further include a brightness sensing unit 310 for determining the brightness of the present or the previous time in the embodiment of the present invention. So that the brightness of the lamp 400 can be sensed.

In the embodiment of the present invention, the brightness controller 300 uses the IIR filter to control the brightness of the lamp 400. However, this is merely an example for facilitating understanding of the present invention, The present invention is not limited to this, and various methods may be used to have a constant time delay from the current brightness to the target brightness and gradually change the brightness.

On the other hand, as described above, the brightness control unit 300 gradually changes the brightness using the IIR filter when the vehicle is normally traveling in a state in which the lamp is already on, The process of gradually changing the brightness of the lamp may be omitted when the brightness must be changed at a time such as when the lamp is turned off or the brake lamp is turned on by operating the brake.

4 is a flowchart showing a method of controlling lamp brightness of a vehicle according to an embodiment of the present invention. 4 is an example of controlling the brightness of the lamp according to the weather while the vehicle is normally traveling when at least one of the lamps installed in the vehicle is on.

As shown in the figure, in the method of controlling the lamp brightness of the vehicle according to the embodiment of the present invention, the weather information is received through the weather information receiving unit 100 during the traveling of the vehicle (S110). At this time, as described above, the weather information receiving unit 100 is provided in the navigation or DMB receiving apparatus to receive weather information or separately receive weather information, and the weather information can be received at predetermined time intervals.

The weather condition around the vehicle is sensed through various sensors 210, 220, 230, and 240 included in the weather condition sensing unit 200 installed in the vehicle (S120). At this time, the weather condition sensing unit 200 can detect various conditions that can determine the weather conditions such as temperature, humidity, propulsion, wiper operation speed, and the like through various sensors 210, 220, 230, have.

The brightness controller 300 determines the target brightness based on the weather information received in step S110 and the weather conditions detected in step S120 in step S130. The target brightness according to the received weather information and the detected weather condition can be variously changed according to the area, the road, etc., and the target brightness can be set before the vehicle departure or after the vehicle departure. In the exemplary embodiment of the present invention, the target brightness is determined by considering the received weather information and the detected weather conditions. However, the present invention is not limited thereto. For example, the received weather information and the detected weather conditions It is possible to determine the target brightness by considering only one.

The brightness controller 300 compares the current brightness with the target brightness (S140). If the current brightness is different from the target brightness, the brightness controller 300 gradually increases or decreases the current brightness to control the brightness to become the target brightness (S150). At this time, the brightness controller 300 controls the brightness to be the target brightness by gradually increasing or decreasing the current brightness using the above-mentioned IIR filter or the like. When the current brightness is changed to the target brightness at a time, This can be confusing. For example, when the brightness controller 300 increases the brightness of the tail lamp to the target brightness in a rainy situation, if the brightness of the tail lamp is increased to the target brightness at a certain time, So that it is difficult to recognize the driver of the surrounding vehicle, thereby preventing confusion in advance.

The method of controlling the lamp brightness of the vehicle as shown in FIG. 4 is one example of increasing or decreasing the brightness of the on-ramp among the lamps installed in the vehicle according to the weather conditions, When the lamp needs to be turned on immediately or when the brightness must be increased at a time, such as when a specific lamp is turned on in a lamp capable of performing various functions together such as a rear combination lamp, Can be omitted.

In addition, in the above-described FIG. 4, the weather condition is detected and the weather condition is determined after receiving the weather information. However, the present invention is not limited to this, .

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
