DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1, a controller (not shown) for controlling the operation of the mood lamp 30 based on the engine speed (RPM) signal, the audio output signal, the ambient temperature signal and the navigation signal 20 are shown.

Referring to FIG. 2, the controller 20 is for controlling the operation of a mood lamp installed in a vehicle. The controller 20 is a 2-channel CAN based on a 32-bit MCU. ), And also has an external EEPROM for storing the color and mode functions of the mood lamp 30 in use.

Referring to FIG. 3, the mood lamp 30 includes a three-color LED having RGB (RED, GREEN, BLUE) as a light source 34 And has two or more light sources 34 for expressing the change in the position of the light in the right and left direction and realizes light of various colors through the synthesis of RGB light.

Referring to FIG. 4, the mood lamp 30 is composed of an indirect reflection optical system for realizing indirect light using the light guide 32.

The light guide 32 functions to transmit light emitted from the light source 34 and adjust the brightness of the light. The light guide 32 is used to realize the indirect light of the mood lamp 30 in the form of a line or a surface, The light source 34 can be mounted on the end or corner of the light guide 32 to realize light in the form of a line or a plane by light transmission (light emitted from the light source moves along the light guide).

At this time, in the mud lamp optical system, the light guide 32 is supported by the upper garnish 36 and the back cover 37, and a lower garnish 38 having a slope for light reflection and light emission is provided under the light guide 32 Respectively.

3 and 4, the light source 34 of the mood lamp 30 includes a first light source 34a mounted on the right end of the first light guide 32a and a first light source 34b mounted on both right and left sides of the second light guide 32b And a second light source 34b and a third light source 34c mounted on the end.

The light source 34 can adjust brightness intensity of the light when the input current increases, and the light guide 32 is designed to have uniformity of light through an optic considering the size, depth, and the like.

That is, the mood lamp 30 has a multicolor light source capable of emitting light of various colors, and uses a light guide 32 for transmitting light of the light source 34 to emit light in a line or plane form And an indirect reflection optical system.

The information representation using the light source of the mood lamp 30 is largely classified into a static expression method and a variation expression method.

In the case of the static representation method, the light color and brightness representation of the light source 34 is fixed without changing in the initially selected light color and stepping (until another / new external signal is generated) , The brightness and color values set once are displayed unchanged and constantly.

In the case of the variation expression method, the light source 34 expresses information through changes in brightness and color of light and variation in operation order of light sources. In the case of color change, for example, the information can be expressed by changing the color to red -> blue -> red. In the case of brightness change, for example, the light intensity is changed from low to high, ≫ to " low ".

When the information is expressed through the change in the operating sequence of the light source 34 among the variation expression systems, the light source 34 disposed on the right and left sides with respect to the longitudinal direction of the mood lamp 30 and the light guide 32 The first light source 34a is first turned on and the second light source 34b and the third light source 34c are operated with a time lag therebetween to change the brightness intensity of the light in the longitudinal direction, (See Fig. 5 (a)). In this case, as shown in Fig.

The third light source 34c is first turned on first and then the second light source 34b and the first light source 34b are turned on first, 34a are operated with a time difference to change the intensity of light in the longitudinal direction, it is possible to realize a change in position of the light as if the light linearly moves from one side to the other side (refer to FIG. 5 (b)) .

That is, by varying the brightness intensity of the light in the longitudinal direction through the change in the operation sequence of the light source 34 arranged in the longitudinal direction of the mood lamp 30 and the light guide 32, And the corresponding information can be expressed.

The mood lamp operation interface 10 is for controlling the color and brightness of the light source light of the mood lamp 30. The mood lamp operation interface 10 transmits a signal generated by a passenger operation to a controller, 30).

As the mood lamp operation interface 10, a setting window such as a touch-screen type monitor capable of displaying is used, and a separate manual switch can be used together. In this case, the monitor can be used together with a cluster or a navigation of a vehicle.

The passenger can select the light color and brightness of the mood lamp 30 using the mood lamp operation interface 10 and the controller 20 stores information of the initial brightness and color used / The light brightness and color of the mood lamp 30 are determined according to the brightness and color information stored in the controller 20 when the mood lamp 30 is turned on.

After the vehicle is started, the passenger is able to select and adjust the light color and brightness through the mood lamp manipulation interface 10 so that the selected color and brightness are represented through the mood lamp optical system.

Referring to FIG. 6, the mood lamp operation interface 10 (hereinafter also referred to as an " interface ") is divided into different colors at different angles in the circumferential direction to adjust the color of light, It is divided into different brightness and the brightness of the light can be adjusted.

The 'initial light color and brightness' of the mood lamp 30 is the color and brightness before the new user selection using the interface 10 and the 'selected light color and brightness' Brightness.

The light source 34 of the mood lamp 30 is not directly changed from the initial light color and brightness to the selected light color and brightness but is changed to the color and brightness of the selected light by the controller 20, The brightness of the selected light is expressed by varying stepwise from the initial light color and brightness according to the 'brightness path'.

For example, as shown in FIG. 7, when the initial light color and brightness are red 1 (R1) and the selected light color and brightness is blue 1 (B1), red 1 (R1) -> red 2 (R3) -> Blink (OFF) -> Blue 3 (B3) -> Blue 2 (B2) -> Blue 1 (B1) The light color of the mood lamp 2 (P2) and the selection light color and brightness is green 1 (G1), purple 2 (P2) → purple 3 (P3) → blink (OFF) → green 3 (G3) → green 2 (G2) > Green 1 (G1) changes the light color and brightness of the mood lamp 30.

For this purpose, a path map for determining the color and brightness path is pre-built and stored in the controller 20 based on the initial light color and brightness, the selected light color and brightness selected by the passenger, The brightness and the brightness of the mood lamp 30 are changed according to the determined color and brightness path using the path map.

By gradually changing the light color and brightness of the mood lamp 30 according to the color and brightness path, it is possible to change the color and brightness of the passenger's light color and brightness from the initial light color and brightness without applying the color and brightness path. It is possible to prevent the heterogeneity of expression.

When the light color and brightness of the mood lamp 30 are changed according to the color and brightness path, the time required to express the color and brightness of the selected light is as short as one second.

The light color and brightness of the mood lamp 30 expressed in this manner are maintained without fluctuation without a separate external signal input.

Thus, the mood lamp 30 maintains the selected light color and brightness set using the interface 10 by the passenger.

When an external signal (an external signal of the mood lamp) generated in the vehicle is input in the state that the color and brightness of the mood lamp 30 are set, the controller 20 generates a mood lamp (30).

An engine speed signal, an audio output signal, an outside temperature signal, a navigation signal, and an interface signal are set as an external signal for interlocking the mood lamp 30 (see FIG. 1).

First, when the engine speed signal is inputted, the light brightness of the mood lamp 30 is controlled to be varied in conjunction with the engine speed signal.

Different reference engine speeds (RPM) and speed ranges are applied to the stop / travel state, and Table 1 below shows an example of controlling the light brightness of the mood lamp 30 in conjunction with the engine speed signal during driving .

As shown in Table 1, when the engine speed range is 1000 RPM to 4000 RPM and the set reference engine speed is 2500 RPM when the vehicle is running at a speed of 5 km / h or more, the controller 20 outputs the set brightness value The light brightness of the mood lamp 30 fluctuates to 10% of the set brightness value when the received engine speed signal is 500 RPM or more and 1000 RPM or less, If the speed signal exceeds 1000RPM and below 2500RPM, the light brightness of the mood lamp (30) will fluctuate to 10 to 80% of the set brightness value. If the received engine speed signal is more than 2500RPM and less than 4000RPM, The light brightness of the lamp 30 is varied and when the received engine speed signal exceeds 4000RPM, the light brightness of the mood lamp 30 is controlled to be 100% of the set brightness value.

When the vehicle is traveling at a constant speed, the light brightness of the mood lamp 30 is controlled by the reference light intensity.

The engine speed signal can be received from an in-vehicle engine controller (ECU) or an engine management system (EMS).

Next, when an outside temperature signal is inputted, the controller 20 changes and controls the light color of the mood lamp 30 in conjunction with the outside temperature signal.

For example, the light color of the mood lamp 30 is changed according to the ambient temperature condition using the detection value of the ambient temperature measurement sensor for the automotive air conditioning system.

The light color according to the outside temperature varies according to a predetermined temperature condition. For example, when the outside temperature is below 10 ° C, the light color of the mood lamp 30 is changed by the red color, and when the temperature is 10 to 25 ° C, 30) is changed, and when the temperature is 25 占 폚 or higher, the light color of the mood lamp 30 is changed and controlled in blue color.

The outside air temperature signal can be received from a full automatic temperature control (FATC) which obtains the detection value of the in-vehicle outside air temperature measuring sensor.

In addition, when an audio output signal is input, the controller 20 changes and controls the light color and brightness of the mood lamp 30 in conjunction with the audio output signal.

That is, the controller 20 uses the output generated from the audio (sound device) mounted on the vehicle as a base signal for controlling the color and brightness of the mood lamp 30. As audio output signal, sound pressure or frequency output from audio can be used.

For example, if the audio sound pressure is high, the controller will accept it as a stronger signal, resulting in stronger light brightness or light color variation.

The controller 20 operates the mood lamp 30 in conjunction with the audio output signal when the music reproduction signal is input from the AVN (audio, video, navigation) high signal is input to the controller 20. [

For example, the operation specifications of the mood lamp 30 based on the audio output signal can be changed by interchanging the light intensity of the mood lamp 30 with the sound source size of the audio, When the outdoor temperature signal is set as the interlocking condition, the light intensity of the mood lamp 30 is changed according to the size of the sound source when the ambient temperature signal is generated, and the light color of the mood lamp 30 is interlocked according to the outdoor temperature signal Change it.

When the navigation signal is input, the controller 20 divides the type of the navigation signal into the safety signal and the direction signal, and interlocks the mood lamp 30 with the navigation signal.

The navigation signal may be a 'safety signal' related to driving safety such as a forward speed signal or an obstacle signal depending on the driving environment, or a 'direction signal' related to the driving direction, Respectively.

That is, since the navigation signal represents the safety signal and the direction signal according to the driving situation, it is possible to interlock the mood lamp 30 by dividing the navigation signal.

Accordingly, when the navigation signal is input, the controller 20 distinguishes between the safety signal and the direction signal. If the navigation signal is a safety signal, the first light source 34a and the second light source 34b The first light source 34a and the second light source 34b on the left side of the mood lamp 30 in the case of a direction signal can be controlled by controlling the third light source 34c and the right light source 34c in the same manner, And the third light source 34c on the right side can be differentiated to represent the signal information (see FIGS. 4 and 5).

4 and 5A, when the first light source 34a provided on the left side of the mood lamp 30 is first turned on and the second light source 34b is turned on, The brightness of the light in the longitudinal direction of the mood lamp 30 is adjusted by turning off the light source 34a and then turning off the second light source 34b while turning on the third light source 34c provided on the right side of the mood lamp 30, A change in the position of the light as if the light moves from the left side where the first light source 34a is located to the right side where the third light source 34c is located is realized.

5 (b), the third light source 34c is first turned on, the second light source 34b is turned on, the third light source 34c is turned off, and then the first light source 34a is turned on The second light source 34b is turned off while the third light source 34c is being operated to change the position of the light from the right side where the third light source 34c is located to the left side where the first light source 34a is located.

The second light source 34b and the third light source 34b are arranged such that the operating time difference between the first light source 34a and the second light source 34b is longer than the operating time difference between the first light source 34a and the second light source 34b, It is preferable to set the operating time difference of the second switch 34c to be long.

On the other hand, when a plurality of external signals are received, the controller 20 distinguishes the presentation method to represent a plurality of the corresponding information.

For example, in the case where the mood lamp 30 displays the setting information of the interface 10 in a static expression mode in which the light color and the brightness are not changed, It is possible to express information about an external signal displayed in a variation expression manner by changing the brightness of the light while maintaining the light color of the external signal displayed in the method.

An external signal for which information is expressed by a variation expression system that expresses information based on light color and brightness variations of the mood lamp 30 includes a navigation signal, an engine speed signal, an audio output signal, and an outside temperature signal.

When a plurality of external signals are generated and input to the controller 20, an output signal of the mood lamp 30 (that is, an output signal of the mood lamp 30 expressing information of the external signal) In this case, the display priority of the external signal is determined and the output signal of the mood lamp 30, which is operated in conjunction with the external signal, can be distinguished according to the determination result.

Expression priorities of external signals are information directly related to driving safety, and include notification information (or safety information) about situations in which the driver or passenger must recognize the information and take measures against it, and information that is not directly related to driving safety And can determine the action of the driver or the passenger as the expression information which does not require separately.

Accordingly, the notification information corresponds to a navigation signal that provides overspeed notification information, traffic information, and driving direction information as a priority order of the presentation information, and the presentation information includes a set signal of an interface, an outside temperature signal, Engine speed signal, and audio output signal.

Also, in order to express information about a plurality of external signals, the controller 20 distinguishes whether the external signal is a long-term representation signal or a short-term representation signal.

The long-term display signal is a signal indicating the lightness and the brightness of the mood lamp 30 before the generation of another external signal requiring the light color and brightness variation of the mood lamp 30, ), That is, a signal continuously displayed until another external signal that varies at least one of light brightness and hue of the mood lamp 30 is generated, An engine speed signal, and an audio output signal.

The short-term representation signal is used to generate an external signal that requires information representation through light color and brightness variations of the mood lamp 30 after the representation of an external signal through light color and brightness control of the mood lamp 30 Thereafter, the navigation signal is a signal for stopping the information representation of the external signal after a predetermined period of time even if there is no other external signal requiring the light color and brightness variation of the mood lamp 30 again.

That is, in the case of a navigation signal, information is temporarily displayed only through the mood lamp 30 even if no other external signal for interlocking the mood lamp 30 is generated.

Therefore, when information is expressed by a long-term representation, that is, in the case of a long-term representation signal, information representation continues for a relatively long time before generation of another external signal, and information representation is performed in a short- Information is expressed only for a certain period of time (or for a relatively short period of time).

Hereinafter, a mud lamp control method of the controller 20 that has acquired an external signal will be described with reference to FIGS. 8 to 11. FIG.

8, when at least one of an engine speed signal, an audio output signal, an outside temperature signal, a navigation signal, and an interface signal set as an external signal for interlocking the mood lamp 30 is detected and received, The number of external signals is calculated and judged, and the case where there are one external signal and two or more external signals are distinguished.

When the external signal is 1, as described above, the operation of the mood lamp 30 is controlled by the expression corresponding to each external signal to perform information representation using the light of the mood lamp 30.

If there are two or more external signals, the information presentation method using the light of the mood lamp 30 is determined based on the information presentation method of the primary external signal and the information presentation method of the secondary external signal.

Here, the primary external signal is an external signal that the mood lamp 30 represents first, and the secondary external signal is an external signal that the mood lamp 30 expresses after the primary external signal.

An external signal in which a primary external signal is an external signal in which information is represented in a static representation manner (that is, a static representation signal) and a secondary external signal is information represented in a dynamic representation manner (i.e., ), The information of the primary external signal is expressed through the light color of the mood lamp 30 and the information of the secondary external signal is expressed through the light brightness variation of the mood lamp 30.

If the primary external signal is an external signal expressed by a variation expression method and the secondary external signal is an external signal expressed by a static expression system, information of the primary external signal is expressed through the light brightness variation of the mood lamp 30 And expresses the information of the secondary external signal through the light color of the mood lamp 30. [

If the primary external signal is an external signal represented by a static expression system and the secondary external signal is also an external signal expressed by a static expression system, only the information of the secondary external signal through the color and brightness of the mood lamp 30 Express.

If the primary external signal is an external signal expressed by a variation expression method and the secondary external signal is an external signal expressed by a variation expression method, the presentation priority of the primary external signal and the secondary external signal is determined, And the like.

In the case where the presentation priority is changed from the second order to the first order according to the generation order of the external signal, the information of the external signal is expressed according to the representation method of Case 1 by dividing the case 1 into one (see FIG. 9) In the case where the signal is changed in the second order and the second order is changed in the second order, the information of the external signal is divided according to the case 2 in the case 2 (refer to FIG. 10) The case 3 is divided into the case 3 and the information of the external signal is expressed according to the expression system of the case 3 (see FIG. 11).

First, when the presentation priority of the primary external signal and the secondary signal varies from the second rank to the first rank, the information of the external signal is represented according to the expression of the case 1. In this case, the primary external signal and the secondary external signal The information of the previous external signal (primary external signal) and the information of the subsequent external signal (secondary external signal) are changed only by changing the color and brightness of the light of the mood lamp 30 It is difficult to distinguish differences.

For example, in a case where the light color and brightness of the mood lamp 30 are controlled in conjunction with the navigation signal while controlling the light color and brightness of the mood lamp 30 in conjunction with the audio output signal, It is difficult to distinguish the difference between the primary external signal and the secondary external signal only by the variation.

Accordingly, in order to express information by distinguishing the difference between the primary external signal and the secondary external signal, a dimming (dimming) function that minimizes the light brightness of the mood lamp 30 momentarily or for a predetermined time before the information representation of the secondary external signal ) Function.

That is, as shown in FIG. 9, a dimming signal is output between the mood lamp control signal for information representation of the primary external signal and the mood lamp control signal for information representation of the secondary external signal, And the second external signal, in which information representation is performed.

At this time, since the first order signal is a short-term representation signal (navigation signal) temporarily represented, the dimming signal is output after the completion of the representation of the first order signal, and then the second order signal, which is a long-

Next, even when the presentation priorities of the primary external signal and the secondary external signal are changed from the second order to the first order or from the first order to the second order, as shown in FIG. 10, By outputting a dimming signal between the control signal and the mood lamp control signal for the information representation of the secondary external signal, it is possible to distinguish between the primary external signal and the secondary external signal, in which information is represented by the same expression system do.

In this case, since the secondary external signal is a long-term representation signal such as an audio output signal or an engine speed signal, a secondary external signal among the primary external signal and the secondary external signal is determined as the final signal after the output of the dimming signal, The information representation of the secondary external signal continues until another external signal is generated.

For example, when the secondary external signal is an engine speed signal, the information of the engine speed signal is expressed through the light brightness variation of the mood lamp according to the engine speed signal after the dimming signal is output.

In other words, when the display priorities of the primary external signal and the secondary external signal are different from each other, or when the display priorities of the primary external signal and the secondary external signal are both 2, A dimming signal is generated between the mood lamp control signal and the mood lamp control signal determined in conjunction with the secondary external signal so that the information representation can be distinguished between the primary external signal and the secondary external signal.

The navigation signal, which is a first order signal, may include a direction signal having information related to the traveling direction and a safety signal having information related to the traveling safety, and may be expressed as redundant. In this case, The presentation priority of the signal is maintained in the order of 1 to 1.

11, the information presentation method is determined based on the type of the primary external signal and the secondary external signal (i.e., the type of the navigation signal). In this case, If the primary external signal is a direction signal and the secondary external signal is a safety signal, or if the primary external signal is a safety signal and the secondary external signal is a direction signal, that is, the primary external signal and the secondary external signal When either one is the safety signal of the navigation and the other is the direction signal, the direction signal is expressed through the light brightness fluctuation of the mood lamp 30 and the safety signal is expressed through the light color fluctuation of the mood lamp 30 .

When both the primary external signal and the secondary external signal are safety signals, or when both the primary external signal and the secondary external signal are direction signals, only the secondary external signal is used as the final signal for interlocking the mood lamp 30 Specifically, only the information of the secondary external signal is expressed through light brightness and color variation of the mood lamp 30, or by changing the light position of the mood lamp 30 Only the information of the secondary external signal is expressed.

According to the mood lamp control method of the present invention, it is possible to display a plurality of information on an external signal by controlling the light color and brightness of the mood lamp in various ways in conjunction with an external signal.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. Modifications are also included in the scope of the present invention.
