Description

  The present invention relates to a vehicular lamp, and more particularly to a vehicular lamp that is capable of displaying information while being alerted during a braking operation or the like.

  2. Description of the Related Art Among vehicle marker lights, a brake lamp or an indicator lamp is known that includes a plurality of LEDs.

  For example, in Patent Document 1 below, a desired pattern is displayed, for example, by increasing or decreasing the light emitting area according to the amount of depression of the brake, or by performing a sequential display that flows in a turning direction during the blinker display. An automotive rear combination lamp capable of performing the above is described. According to such a rear combination lamp for an automobile, characters, symbols, etc. can be displayed and a message can be displayed.

  Patent Document 2 below discloses a lamp system for a vehicle that includes a plurality of LEDs that display a direction change and a brake at the same time when an operation for changing the traveling direction of the vehicle is performed simultaneously with braking the vehicle. Have been described. In this lamp system, it is possible to change the color according to the display pattern.

  By the way, the following Patent Document 3 describes a display device for a vehicle that can display information toward the outside of the vehicle by projecting an image on the surface of a vehicle body.

JP-A-01-197141 JP 2006-213235 A JP2015-148678A

  In the above Patent Documents 1 and 2, an indication in a state in which the vehicle is running in a normal state, an idling state, or the like in which the brake operation or deceleration is not performed, and a display in a state in which the brake operation or deceleration is performed There is no mention of the relationship. In addition, like the vehicle display device described in Patent Document 3, there is a need to display information toward the outside of the vehicle.

  Therefore, the present invention is intended to provide a vehicular lamp that is capable of alerting a user during a braking operation while enabling information display.

  In order to achieve the above object, a vehicle lamp according to one aspect of the present invention has a matrix of pixels including red display dots that emit red light and other color display dots that emit light of a color other than red. And a display that emits light toward the outside of the vehicle, and a control unit that receives at least one of a signal indicating a brake operation and a signal indicating a deceleration, and controls the lighting state of each of the pixels. The control unit controls each of the pixels so that at least a part of the display becomes an image display area for displaying an image in a non-input state of a signal indicating a brake operation and a signal indicating a deceleration, and the brake operation In an input state of at least one of the signal indicating the deceleration and the signal indicating the deceleration, each of the image display areas is set to be a red emphasis area. In the red emphasis region, the relative luminance of red light with respect to the luminance of light of a color other than red in the input state is such that the light of a color other than red before entering the input state. It is characterized by being higher than the relative luminance of red light with respect to luminance.

  According to such a vehicular lamp, in a non-input state where a signal indicating brake operation and a signal indicating deceleration are not input to the control unit, such as during normal driving or idling, the vehicle lamp is at least a part of the display. Information can be displayed in the image display area. In the input state in which at least one of the signal indicating the brake operation and the signal indicating the deceleration is input to the control unit, the brightness of the red light is different in the red enhancement region which is at least a part of the image display region. Higher than the brightness of the color. Accordingly, at least a part of the image display area becomes red as compared to before the braking operation or the deceleration. This image display area is an area where information is displayed as described above, and is an area where attention is easily gathered from outside the vehicle. In this way, a part of the region that is easily noticed from outside the vehicle becomes red due to the brake operation or deceleration, so that attention can be given during the brake operation or the like.

  It is preferable that the red emphasis area coincides with the image display area.

  In this case, while prompting attention, there is no area that newly shines along with the brake operation or the like, so that natural attention can be set.

  Alternatively, it is preferable that the image display area is a partial area of the display, and the red emphasis area is an entire area of the image display area and at least another area of the display.

  In this case, the area where red is emphasized is larger than the area where the image is displayed. Therefore, a stronger alert can be issued.

  In addition, when the red display dot in the red emphasis region is lit before the input state, the control unit starts from the red display dot in the red emphasis region in the input state. It is preferable to control each of the pixels so that the luminance of emitted light is higher than that before the input state.

  In the red emphasis region, the red light is enhanced and the red light is more emphasized, and can be alerted more effectively during a braking operation or the like.

  Each of the pixels in the red enhancement region further includes a second red display dot that emits red light, and the control unit is configured to cause the second enhancement unit in the red enhancement region in the non-input state. It is preferable that the red display dots are not lit and that the respective pixels are controlled so that the second red display dots in the red emphasis region are lit in the input state.

  When the second red display dot that is not lit in the non-input state is lit in the input state, the red light in the red emphasis area is more emphasized, and more effective alerting is performed during braking operation, etc. Can do. In particular, when each pixel is controlled so that the luminance of light emitted from the red display dot is higher than that before the input state as described above, if the second red display dot is lit in the input state, The red light in the input state is further emphasized, and can be alerted more effectively during a braking operation or the like. Note that the pixels in the region other than the red emphasis region may include the second red display dot.

  In the input state, the control unit preferably controls each of the pixels so that the other color display dots in at least a part of the red emphasis region are lit.

  In the input state, the red light in the red emphasis region is emphasized as described above, so that attention can be given during a braking operation or the like. In this state, since the other color display dots are turned on in the red emphasis area, information can be displayed while calling attention in the red emphasis area.

  In this case, the control unit controls each of the pixels in the input state so that the luminance of light emitted from the other color display dots in the red emphasis region is lower than that before the input state. Is preferred.

  In the case of a brake operation or the like, alerting is often more important than information display. Therefore, by reducing the brightness for displaying information, it is possible to perform a display that emphasizes alerting while maintaining the information display.

  Alternatively, the control unit preferably controls each of the pixels so that the other color display dots in the red emphasis region are not lit in the input state.

  In this case, it is possible to perform a display that emphasizes the attention at the time of braking operation or the like.

  As described above, according to the present invention, it is possible to provide a vehicular lamp that can be alerted during a braking operation or the like while enabling information display.

  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the vehicle lamp which concerns on this invention is illustrated with an accompanying drawing. The embodiments exemplified below are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. The present invention can be modified and improved from the following embodiments without departing from the spirit of the present invention.

  FIG. 1 is a diagram illustrating an example of a vehicle on which a vehicular lamp according to the present embodiment is mounted. FIG. 1 is a view of the vehicle VE as viewed from the rear side. As shown in FIG. 1, the vehicle VE of the present embodiment includes a vehicle lamp 1. The vehicular lamp 1 according to the present embodiment is a marker lamp. Therefore, one vehicular lamp 1 is provided in each of the left and right directions on the back surface of the vehicle VE.

  FIG. 2 is a block diagram of the vehicular lamp 1 in the present embodiment. As shown in FIG. 2, the vehicular lamp 1 according to this embodiment includes a display 2 and a control unit 3 as main components. As shown in FIG. 1, the display 2 is exposed to the outside from the vehicle VE and irradiates light toward the outside of the vehicle VE. In order to simplify the description, the display 2 of FIG. 2 has a different external shape from the display 2 of FIG.

  FIG. 3 is a diagram illustrating pixels of the display 2. As shown in FIG. 3, the display 2 has a plurality of pixels 21 arranged in a matrix. Each pixel 21 of the display 2 includes a red display dot 21R that emits red light, a green display dot 21G that emits green light, and a blue display dot 21B that emits blue light. Yes. Therefore, in the present embodiment, the display can perform RBG color display. Further, the green display dot 21G and the blue display dot 21B can be understood as other color display dots that emit light of a color other than red. Therefore, the display 2 is a display in which the pixels 21 including the red display dots 21R that emit red light and the other color display dots that emit light of colors other than red are arranged in a matrix.

  As shown in FIG. 2, a scanning line driving circuit 25 </ b> H is disposed on the side of the display 2, and a data line driving circuit 25 </ b> V is disposed on the lower side of the display 2. The scanning line driving circuit 25H and the data line driving circuit 25V are electrically connected to each display dot of each pixel, and a voltage is applied or a current flows from the scanning line driving circuit 25H and the data line driving circuit 25V. As a result, each display dot is turned on or off. Further, the brightness of each dot is adjusted by controlling the magnitude of the voltage and current from the scanning line driving circuit 25H and the data line driving circuit 25V. Examples of such a display 2 include an organic EL display, a liquid crystal display, and a micro LED display.

  The control unit 3 is electrically connected to the scanning line driving circuit 25H and the data line driving circuit 25V, and controls the lighting state of each pixel 21 of the display 2. The control unit 3 performs this control based on a signal input to the control unit 3 from the outside. In the present embodiment, the control unit 3 is electrically connected to a control device 4 such as an ECU (Engine Control Unit) of the vehicle VE, an acceleration sensor 5, an image display instruction unit 6, and the like. The control device 4 of the vehicle VE monitors at least the brake operation, and outputs a signal indicating the brake operation when the brake operation is performed. Further, the acceleration sensor 5 of the present embodiment outputs a signal indicating deceleration when at least the vehicle VE is decelerated. Further, the image display instruction unit 6 outputs a signal for displaying a predetermined image on the display 2. This signal includes information related to the contents of the image. This predetermined image is not particularly limited. Therefore, the predetermined image may be a still image or a moving image, or may display a predetermined character or the like.

  Next, operation | movement of the vehicle lamp 1 of this embodiment is demonstrated. FIG. 4 is a diagram illustrating a control flowchart of the control unit 3. In step SP1, the control unit 3 detects the image signal from the image display instruction unit 6, and when the image signal for displaying a predetermined image is input from the image display instruction unit 6, the process proceeds to step SP2. .

  In step SP2, the control unit 3 controls each pixel 21 so that a predetermined image is displayed on the display 2. Specifically, the control unit 3 drives the scanning line driving circuit 25H and the data line driving circuit 25V based on information related to the content of the image included in the image signal from the image display instruction unit 6. The scanning line driving circuit 25H and the data line driving circuit 25V adjust the applied voltage and the flowing current, and turn on or off the red display dot 21R, the green display dot 21G, and the blue display dot 21B of each pixel 21. Adjust the brightness when lighting. That is, the control unit 3 controls the lighting and non-lighting of each display dot of each pixel 21 and the luminance of light emitted from each display dot via the scanning line driving circuit 25H and the data line driving circuit 25V. To do. Thus, a predetermined image is displayed on the display 2 by the control unit 3 controlling each pixel 21.

  FIG. 5 is a diagram illustrating a state in which the display 2 displays a predetermined image. As shown in FIG. 5, in the present embodiment, an image is displayed in a partial area 2 </ b> A of the display 2. Therefore, this area 2A can be understood as an image display area. Specifically, the color of light emitted from each pixel 21 in the region 2C in the region 2A is different from the color of light emitted from each pixel 21 in the region 2B around the region 2C. The shape of this region 2C is the shape of the characters “Slow Driving”. The color of this character, that is, the color of light emitted from each pixel 21 in the region 2C is not particularly limited, and is, for example, orange. In this case, in each pixel 21 in the region 2C where the character is displayed, for example, the red display dot 21R and the green display dot 21G are lit, and the blue display dot 21B is not lit. Moreover, the color of the light emitted from each pixel 21 in the region 2B is not particularly limited, and is, for example, blue. In this case, in each pixel 21 in the region 2B around the character, the blue display dot 21B is lit, and the red display dot 21R and the green display dot 21G are not lit. Further, in this embodiment, nothing is displayed in the area 2D around the area 2A including the area 2B and the area 2C, and each display dot of each pixel 21 is not lit. Thus, in this embodiment, an image representing characters is displayed in a partial area 2A of the display 2.

  On the other hand, if the image signal for displaying a predetermined image is not input from the image display instruction unit 6 in step SP1, the control unit 3 proceeds to step SP3.

  In step SP3, the control unit 3 controls each pixel 21 so that an image is not displayed on the display 2. That is, the control unit 3 controls each pixel so that light is not emitted from each pixel of the display 2. Specifically, the control unit 3 drives the scanning line driving circuit 25H and the data line driving circuit 25V, and the driven scanning line driving circuit 25H and the data line driving circuit 25V adjust the applied voltage and the flowing current. Then, the red display dot 21R, the green display dot 21G, and the blue display dot 21B of each pixel 21 are turned off.

  In step SP2, the control unit 3 controls each pixel 21 so that a predetermined image is displayed on the display 2, and then proceeds to step SP4. In step SP3, the control unit 3 controls each pixel 21 so that no image is displayed on the display 2. Then, the process proceeds to step SP4.

  In step SP4, the control unit 3 detects a signal indicating the brake operation from the control device 4 and a signal indicating the deceleration from the acceleration sensor 5, and at least one of the signal indicating the brake operation and the signal indicating the deceleration is the control unit. If the input state is input to 3, the process proceeds to step SP5.

  When the control unit 3 proceeds to step SP5 via step SP2, in step SP5, the control unit 3 displays red for the luminance of light of a color other than red in at least a part of the region 2A that is the image display region of the display 2. Red emphasis that controls each pixel 21 such that the relative luminance of the light of the red light is higher than the relative luminance of the red light with respect to the luminance of the light of a color other than red in the region 2A before entering the input state It becomes a mode. In the red enhancement mode, the control unit 3 controls each pixel 21 so that at least a part of the area 2A, which is an image display area, becomes red than before the input state. This reddish area is a red emphasis area. Here, an example of control when the red enhancement mode is set in step SP5 via step SP2 is shown below.

  First, a first example in which the red enhancement mode is set in step SP5 via step SP2 is shown. FIG. 6 is a diagram illustrating a first example of display on the display 2 when the control unit 3 is in the red enhancement mode. When the process proceeds to step SP5 via step SP2, in step SP5 of this example, the red display dot 21R in the pixel 21 in the area 2A that is the image display area of the display 2 is turned on and the emitted light has a predetermined luminance. Thus, the control unit 3 controls each pixel. Further, in step SP5, the control unit 3 controls each pixel so that the green display dot 21G and the blue display dot 21B which are other color display dots in the pixel 21 in the region 2A are not lit. At this time, the pixels 21 in the region 2D other than the region 2A maintain the lighting state in step SP2. In this case, the region where red is emphasized in the red enhancement mode matches the region 2A where the image is displayed before the red enhancement mode is entered. Therefore, in this example, the image display area and the red emphasis area match. Thus, since the image display area and the red emphasis area coincide with each other, it is possible to make a natural alert because there is no area that newly shines along with a brake operation or the like while prompting an alert.

  Next, a second example in which the red enhancement mode is set in step SP5 via step SP2 is shown. Although not particularly illustrated, in step SP5 of this example, the red display dot 21R is lit so that the light emitted from the red display dot 21R has a predetermined luminance in the pixels 21 of all the areas of the display 2, and the like. The control unit 3 controls each pixel so that the green display dot 21G and the blue display dot 21B which are color display dots are not lit. In this case, all areas 2A of the image display area, which is a partial area of the display 2, are set as red emphasis areas, and further, areas 2D other than the image display area, which are other partial areas of the display 2, are also highlighted in red. It is considered as an area. In this case, the area where red is emphasized is larger than the area 2A where the image is displayed. Therefore, a stronger alert can be issued. Moreover, in this example, since the display 2 generally shines red, higher alerting ability can be exhibited. In step SP2, a part of the area 2D, which is another part of the display 2, may be set as a red emphasis area, and the other part of the area 2D may be turned off. That is, in this example, the image display area is a partial area of the display 2, and the red emphasis area is the entire area of the image display area and the other at least a partial area of the display 2.

  Next, a third example in which the red enhancement mode is set in step SP5 via step SP2 is shown. In this example, similarly to the first example, the area 2A that is the image display area of the display 2 is set as a red emphasis area, and other colors are displayed in a part of the red emphasis area unlike the first example. The Specifically, in each pixel 21 in the region 2A, the red display dot 21R is lit so that the light emitted from the red display dot 21R has a predetermined luminance, and the red display dot 21R is lit. The control unit 3 controls each pixel 21 so that the other color display dot is lit in a part of the pixel. For example, as described above, in step SP2, the red display dot 21R and the green display dot 21G of each pixel 21 in the region 2C shown in FIG. 5 are lit, the region 2C is lit in orange, and the respective regions in the region 2B. The blue display dot 21B of the pixel 21 is lit, and the region 2B is lit blue. Therefore, in this example, in step SP5, for example, the luminance of light emitted from the red display dot 21R and the luminance of light emitted from the green display dot 21G in each pixel 21 of the region 2C remain in the state of step SP2. It is said. Further, the red display dots 21R of the respective pixels 21 in the region 2B around the region 2C are lit with a predetermined luminance, and the other color display dots are not lit. Accordingly, the region 2B is displayed in red. Thus, when each pixel 21 in the region 2A is lit, the region 2B around the region 2C is displayed in red, and the region 2C is displayed in orange. In this case, the information can be displayed while the red light is emphasized to call attention such as a brake operation.

  In the third example, it is preferable that the luminance of the light emitted from the red display dot 21R of each pixel 21 in the region 2C is higher than that in step SP2. That is, when the red display dot 21R in the red enhancement region is lit before entering the input state, the control unit 3 emits from the red display dot 21R in the red enhancement region of the display 2 in the input state. Each pixel 21 is controlled so that the brightness of the light to be emitted is higher than that before the input state. As an example of such control, the red gamma value in the region 2C can be increased at each gradation. By doing so, the color of the region 2C is closer to red than before the input state is reached. However, since the area 2B around the area 2C is displayed in red, the area 2C is displayed in orange rather than the surrounding area 2B. In this case, the information display ability can be weakened and the alerting ability can be made higher than in the third example. In this example, the red gamma value of the entire region 2A may be increased at each gradation. In this case, even when the blue display dot 21B in the region 2B is lit in the input state, the region 2B can be made closer to red than before the input state is entered.

  Next, a fourth example in which the red enhancement mode is set in step SP5 via step SP2 is shown. This example is the same as the third example except that the red display dot 21R of each pixel 21 in the region 2C is not lit. In this case, since the red color is not emphasized in the region 2C, the red emphasized region in this example is the region 2B unlike the third example. That is, a part of the image display area becomes a red emphasis area. In this case, since the area 2B around the area 2C emits red light as described above, it is possible to display information more clearly while calling attention in the area 2B.

  In the third example and the fourth example, the control unit 3 determines that the luminance of the light emitted from the region 2C where the other color display dot is lit is the luminance of the light emitted from the other color display dot in step SP2. It is preferable to control each pixel 21 in the region 2C so as to be lower. That is, in the third example and the fourth example, it is preferable that the luminance of the light emitted from the green display dots 21G of the respective pixels 21 in the region 2C in step SP5 is lower than the state in step SP2. In this case, the light emitted from the region 2C approaches red in step SP5 as compared to the third example and the fourth example. Therefore, the red color is emphasized more and can be alerted.

  Further, in the third example and the fourth example, the control unit 3 may light each pixel 21 in the area 2D of the display 2 in red as in the second example. In the third example, when each pixel 21 in the region 2D is lit red, for example, the control unit 3 controls each pixel 21 so that the red gamma value is increased in each gradation in the entire display 2. Also good.

  In any of the above examples, the luminance of light emitted from the red display dot 21R in step SP5 is higher than the luminance of light emitted from the display dot of each pixel 21 in step SP2. preferable. As described above, the luminance of the red light emitted from the display 2 in the red enhancement mode is made higher than the luminance of the light emitted from the display 2 before entering the red enhancement mode, thereby having a higher alerting ability. it can.

  If the red enhancement mode is set at step SP5 via step SP3, no image is displayed on the display 2 until the process proceeds to step SP5. That is, each pixel of the display 2 is not turned on, or light of substantially the same color is emitted from each pixel with substantially the same luminance. Here, an example of control when the red enhancement mode is set in step SP5 via step SP3 is shown below.

  In step SP5 of this example, in the pixels 21 in a predetermined region of the display 2, the red display dots 21R are lit so that the light emitted from the red display dots 21R has a predetermined luminance. The control unit 3 controls each pixel so that a certain green display dot 21G and blue display dot 21B are not lit. This predetermined area is, for example, the same area as the area 2A in FIG. 5, and the area 2A is a red emphasis area. In this case, each pixel 21 in the region 2A is lit red. Further, in step SP5, in the regions other than the predetermined region, each pixel 21 maintains the non-lighting state in step SP3. As described above, if the predetermined region is the region 2A in FIG. 5, each pixel 21 in the region 2D is maintained in a non-lighted state. In this case, in step SP5, for example, the state is the same as the display on the display 2 shown in FIG. In step SP5 of the present example, the entire display 2 may be a red-enhanced region and shine in red.

  As described above, in both cases of passing through step SP2 and passing through step SP3, light of a color in which red is emphasized is emitted from the display 2 more than before step SP5 in step SP5.

  As described above, in the vehicular lamp 1 according to the present embodiment, the pixels 21 including the red display dots 21R that emit red light and the other color display dots that emit light of colors other than red are in a matrix. And a display 2 that emits light toward the outside of the vehicle VE, and a control unit 3 that controls the lighting state of each pixel 21. And the control part 3 controls each pixel 21 so that at least one part of the display 2 may become an image display area which displays an image in the non-input state of the signal which shows a brake operation | movement, and the signal which shows deceleration. Further, each pixel 21 is controlled so that at least a part of the image display area becomes a red emphasis area in an input state of at least one of a signal indicating a brake operation and a signal indicating a deceleration. In this red emphasis region, the relative luminance of red light with respect to the luminance of light of colors other than red in the input state is relative to the luminance of light of colors other than red before entering the input state. Be higher than the brightness.

  According to the vehicular lamp 1 of the present embodiment as described above, in at least a part of the display 2, a signal indicating brake operation or a signal indicating deceleration is transmitted to the control unit 3 during normal driving or idling. In a non-input state where no input is made, information can be displayed as in step SP2. In an input state in which at least one of the signal indicating the brake operation and the signal indicating the deceleration is input to the control unit, the luminance of the red light is higher than the luminance of the other colors in at least a part of the region. As described above, when the braking operation or the deceleration is performed, the region becomes red, so that attention can be given to the braking operation or the like. Note that the vehicle lamp 1 does not always have to display information in the region of the display 2 as in step SP3 in the non-input state.

(Second Embodiment)
Next, a second embodiment of the present invention will be described in detail with reference to FIG. In addition, about the component which is the same as that of 1st Embodiment, or equivalent, except the case where it demonstrates especially, the same referential mark is attached | subjected and the overlapping description is abbreviate | omitted.

FIG. 7 is a diagram illustrating pixels of the display 2 of the present embodiment. As shown in FIG. 7, each pixel 21 of the display 2 of the present embodiment is different from each pixel 21 of the display 2 of the first embodiment in that it includes a _second red display dot 21R2. In the present embodiment, as a red display dot 21R and second red display dot 21R ₂ is not adjacent, it is the arrangement of RGRB. Incidentally, a red display dot 21R and second red display dot 21R ₂ may be adjacent.

Red display dot 21R ₂ of the second is a non-lighting in the non-input state signal indicating the signal and slow showing braking operation is not input to the control unit 3, at least of the signal indicating the signal and slow showing braking operation One is lit in the input state for input to the control unit 3. Accordingly, the control unit 3 is red display dot 21R ₂ of the second until the red enhancement mode does not light up. Specifically, the control unit 3 becomes red enhancement mode, second red display dot 21R ₂ in the red highlight region is illuminated. For example, the first example, in the third embodiment, the second red display dot 21R ₂ in each pixel 21 in the region 2A is illuminated. Further, for example, in the second example, the second red display dot 21R2 in each pixel 21 of the entire display ₂ is lit. Further, for example, in the fourth example, the second red display dot 21R ₂ is turned in each pixel 21 in the region 2B. Further, when the red enhancement mode is set in step SP5 via step SP3, in step SP5, the second red display dot 21R2 of the pixel 21 in at least a partial region of the display ₂ is lit.

The vehicle lamp of the present embodiment, the second red display dot 21R ₂ which is non-lighting in the non-input state, by lighting in the input state, the red light in the red highlight region is more emphasized, the brake It is possible to call attention more effectively during movements. In particular, when each pixel is controlled so that the luminance of light emitted from the red display dot is higher in the input state than in the input state in at least a part of the red display region as described above. if the lighting in the red display dot 21R ₂ is input state, the red light is more emphasized in the input state can more effectively alert during braking operation and the like. The pixel 21 in a region other than the red highlight region may have a second red display dot 21R _2.

  As mentioned above, although this invention was demonstrated to the example for embodiment, this invention is not limited to these.
