## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation-in-part (CIP) of and claims priority to U.S. Non-Provisional patent application Ser. No. 14/831,954 (Attorney Docket No. HRA-39672) entitled “SYSTEM AND METHOD FOR VEHICLE AMBIENT LIGHTING”, filed on Aug. 21, 2015; the entirety of the above-noted application is incorporated by reference herein.


BACKGROUND
Vehicles typically have interior lighting for illuminating an interior of the vehicle. Vehicle interior lighting can include a variety of different illumination schemes, such as providing an overhead light in a flood light configuration to light the entire interior or providing reading lights concentrating the light into tightly focused spot light configurations useful for reading, for example.
Ambient lighting typically consists of one or more light sources which provide a soft, diffused lighting throughout much of the vehicle interior. Light emitting diodes (LEDs) are used for generating vehicle ambient illumination. White LEDs have been commonly used which provide white ambient lighting. More recently, colored ambient lighting is available. Colored light can be generated using colored lenses over white lights to produce ambient light of a predetermined color as defined by the color of the lens used. Alternatively, LEDs having a color other than white can be used. Combinations of colored Red, Green, and Blue (RGB) LEDs are also used to produce colored ambient lighting.
Many ambient lighting systems do not enable the occupant to choose the color of the ambient light illuminating the vehicle interior. Some systems provide the occupant with a limited choice of preselected ambient lighting colors to choose from. It is desirable to enable the occupant to select her own, personalized color of ambient light for illuminating the vehicle interior.

DETAILED DESCRIPTION
It should be understood that the description and drawings herein are merely illustrative and that various modifications and changes can be envisioned without departing from the present disclosure. It will also be appreciated that the various identified components of the exemplary vehicle ambient lighting system disclosed herein are merely terms of art that may vary from one manufacturer to another and should not be deemed to limit the present disclosure.
The embodiments will now be described with reference to the accompanying drawings, wherein like reference numerals designate corresponding or identical elements throughout the various drawings. Referring now to FIG. 1, a schematic illustration of a vehicle is shown generally at 100. The vehicle can be an automobile, car, truck, minivan, sport utility vehicle (SUV), or another type of vehicle having an interior vehicle ambient lighting system 102. The vehicle ambient lighting system 102 includes a plurality of light emitting diodes (LEDs) which include Red (R1, R2, . . . Ri), Green (G1, G2, . . . Gi) and Blue (B1, B2, . . . Bi) diodes, also known as RGB LEDs 104, which are activated to produce ambient lighting to illuminate the interior of the vehicle 100. The RGB LEDs 104 can also include a plurality of clear LEDs, according to one or more aspects.
An LED driver 106 is electrically connected to the RGB LEDs 104 to selectively activate the individual red, green, and blue LEDs to any desired illumination intensity, thereby creating light of variable intensity having any desired color. One or more power supplies 108 provide the RGB LEDs 104 with sufficient voltage and current to provide the wide range of illumination intensity sufficient for generating any desired color.
A controller 110 is operatively coupled to the LED driver 106 for controlling the operation of the vehicle ambient lighting system 102. The controller 110 is a computing device which includes one or more processors 112 programmed to perform computer-executable instructions embodied on computer-readable storage media or a memory 114. When executed by at the least one processor 112, the computer-executable instructions cause the processor to perform the operations described herein, including controlling the vehicle ambient lighting system 102 to create a personalized, user-defined color of illumination, such as according to the method 200 of FIG. 2.
The controller 110 provides the LED driver 106 with an LED activation scheme for activating select RGB LEDs 104 to sufficient respective illumination intensities so that the combined effect produces ambient light of variable intensity having any desired color, as described in greater detail herein. The controller 110 can also control the vehicle ambient lighting system 102 in a variety of conventional manners such as turning the vehicle ambient lighting system 102 on and off, controlling general illumination intensity, lighting different locations within the vehicle, etc.
A human machine interface (HMI) 116 is operatively coupled to the controller 110 for enabling a user to operate the vehicle ambient lighting system 102. The HMI 116 can include a display 117, such as a touch screen, having a graphical user interface (GUI), for example. The user can control the vehicle ambient lighting system 102 using the HMI 116 to produce ambient lighting of any desired color in a manner described in greater detail herein.
The vehicle 100 includes a camera 118 for use in the vehicle ambient lighting system 102. The camera 118 can be a dashboard camera, a backup camera, or any other suitable camera having an image sensor 120 capable of capturing a color image, also referred to as a digital picture. The image sensor 120 can be a semiconductor charge-coupled device (CCD), or active pixel sensor in complementary metal-oxide-semiconductor (CMOS), or other type of image sensor used in cameras.
The camera 118 includes an image processor 122 which receives color image data for an object captured by the image sensor 120 when the camera is triggered to take a picture. In the examples described herein, the object is a colored surface 124 associated with a color which may be used for desired ambient lighting. The colored surface 124 can be a color swatch, a paint chip, a photograph, or any colored surface from which the user intends to create matching colored ambient lighting in the vehicle 100. The image processor 122 receives the color image data from the image sensor 120 and creates RGB color values which represent the color of the colored surface 124. In one or more embodiments, the image processor 122 is separate from the camera 118. The RGB color values are derived in accordance with an RGB color model appropriate for the specific RGB LEDs 104 used in the ambient lighting system. This RGB color model can be predetermined using LED data supplied at the time of manufacture of the vehicle ambient lighting system 102. For example, the RGB color model can be a sRGB color model. As another example, the RGB color model can be Adobe RGB, which includes a larger range (e.g., gamut) of colors than sRGB, especially in the blues and cyans, to produce a larger variety of ambient lighting colors. The RGB color model can be updated or re-defined at periodic intervals, or as desired.
The controller 110 receives the RGB color values from the image processor 122. For example, the RGB color values can be stored in a color look-up table in the memory 114 of the controller 110. The controller 110 creates an RGB LED activation scheme using the RGB color values for selectively activating the RGB LEDs 104 with sufficient intensity such that the combined effect produces ambient illumination having a color which matches the color of the colored surface 124. The controller 110 communicates with the LED driver 106 using the LED activation scheme for activating the RGB LEDs 104 to produce the colored ambient light. Some or all of the RGB LEDs 104 can be illuminated to produce the appropriate color.
Referring now to FIG. 2, a method of generating vehicle ambient lighting having a personalized, user-defined color is shown generally at 200. A user operates the vehicle ambient lighting system 102 using the HMI 116 described above. The user begins operating the ambient lighting color selection routine using the HMI GUI. The user is instructed to present a colored surface to the camera at 202 and trigger the activation of the camera. Upon receiving the trigger signal at 204, the camera 118 takes an image of the color surface capturing image color information at 206 and sends the image data to the image processor 122. The image processor 122 generates RGB color values representing the color of the colored surface at 208.
The image processor 122 sends the RGB color values to the controller 110 which generates an RGB LED activation scheme at 210 for activating select RGB LEDs 104 at suitable intensities to generate ambient lighting having a color which matches the color of the colored surface, as described above. The controller 110 communicates with the LED driver 106 using the RGB LED activation scheme to activate the RGB LEDs 104 at 212 and produce an interior ambient light having a color which matches the color of the colored surface corresponding to the user defined ambient lighting color selection.
The HMI 116 then queries the user at 214, generating a request or a prompt to save the LED activation scheme. Upon receiving an indication from the user (e.g., the response to the prompt of 214) to save the LED activation scheme in response to the request, the LED activation scheme is saved in memory at 216. The HMI can produce a request that the user enter a storage identifier for the LED activation scheme, according to one or more aspects. Thus, the ambient lighting color selection can be saved using any suitable naming convention and made available for future retrieval.
In one or more embodiments, the LED activation scheme can be saved in association with the user, such as for example, by using a user ID or account number, or in any other suitable manner. The LED activation scheme can be saved in association with the owner of the fob that previously started the vehicle, or activated the ignition. The LED activation scheme is discarded, if not saved.
The HMI then queries the user at 218, generating a request to create another user defined ambient lighting color selection. Upon receiving an indication from the user to proceed, the process is repeated beginning again at 202. Alternatively, if the user chooses not to repeat or continue, the process or method 200 ends at 220.
The systems and methods of generating user defined ambient lighting colors disclosed herein enables a vehicle owner to chose a color to match his or her exact mood and desire, thereby creating a more personalized driving experience.
FIG. 3 is a schematic illustration of a system 102 for generating personalized color of vehicle ambient lighting, according to one or more embodiments. In FIG. 3, a vehicle 100 includes the system 102 for generating personalized color of vehicle ambient lighting. The system 102 includes one or more of the components of the system of FIG. 1. The system 102 includes a controller 110, a human machine interface (HMI) 116, a camera 118, an electronic control unit (ECU) 130 which may be a body control module (BCM), a vehicle entry sensor 140, a telematics unit 150, and one or more lighting systems 160, 170, 180. The camera 118 includes an image sensor 120 and an image processor 122. The controller 110 includes a processor 112 and a memory 114. The HMI 116 includes a display 117. Each one of the first, second, and third lighting systems 160, 170, 180 includes a first, second, and third LED driver (106a, 106b, 106c), a first, second, and third power supply (108a, 108b, 108c), and a first, second, and third plurality of RGB LEDs (104a, 104b, 104c). In one or more embodiments, a single LED driver may drive different groups or pluralities of RGB LEDs 104a, 104b, 104c. Similarly, the RGB LEDs 104a, 104b, 104c may be tied to a common power supply in other embodiments. Regardless, the controller 110 may control different pluralities or groups of RGB LEDs 104a, 104b, 104c. Further, in one or more embodiments, processing performed by the image processor 122 may be alternatively or in combination, performed by the processor 112 of the controller 110 or be separate from both the camera 118 and the controller 110.
In any event, the lighting systems 160, 170, and 180 of the vehicle 100, may be non-driving related lighting systems, such as a puddle light system, an internal ambient lighting system, an external ambient lighting system, etc. One or more of these lighting systems 160, 170, or 180 may be red, green, and blue or RGB capable in a manner consistent with the RGB LEDs 104 of FIG. 1, thereby enabling the lighting systems 160, 170, and 180 to produce most any color by activating different RGB LEDs of the plurality of RGB LEDs. Similarly, the power supplies 108a, 108b, and 108c and the LED drivers 106a, 106b, and 106c may perform similarly to the power supply 108 of FIG. 1 and the LED driver 106 of FIG. 1.
The system 102 for generating personalized color of vehicle ambient lighting of FIG. 3 utilizes the camera 118 to capture a color associated with a user approaching the vehicle, detected by the vehicle entry sensor 140, such as a driver with a key fob, and customize the ambient lighting of one or more of the lighting systems 160, 170, or 180 (e.g., a puddle light system, internal ambient lighting system, or external ambient lighting system, etc.) accordingly. In other words, the ambient lighting may be tuned individually based on the user walking or approaching the vehicle 100.
The vehicle entry sensor 140 may detect presence information associated with a user approaching the vehicle. The vehicle entry sensor 140 may detect this presence information in a variety of ways according to several embodiments. For example, the vehicle entry sensor 140 may be a touch sensor (e.g., capacitive touch sensor, pressure sensor, etc.) on a door or door handle of the vehicle 100. In this example, the vehicle entry sensor 140 detects presence information based on contact between the user and the door or the door handle of the vehicle where the touch sensor is located or mounted. However, it will be appreciated that other types of sensors or proximity sensors may be used to detect presence information of an approaching user. Examples of sensors include capacitive, inductive, magnetic, proximity, passive sensors, optical sensors, thermal sensors, photocells, radar, sonar, wireless, ultrasonic, fiber optic, Hall-effect sensors, etc.
As another example, a key fob may have a magnet mounted thereon and when a user holding the key fob approaches the vehicle, the magnet may trigger the vehicle entry sensor 140 and alert the system 102 for generating personalized color of vehicle ambient lighting that the user is within a proximity or a threshold distance of the vehicle 100. As such, the vehicle entry sensor 140 may detect presence information of a user based on a proximity of the key fob from the vehicle entry sensor 140. In any event, when the vehicle entry sensor 140 detects a user, the ECU 130 or the controller 110 may issue a command to the camera 118 to capture an image of the user 126. For example, the camera 118 may be mounted on the door handle or at a location on the vehicle 100 which enables a clear shot or image of the user 126 to be taken.
The controller 110 may order the camera 118 or the image sensor 120 of the camera 118 to capture an image of the user 126. In one or more embodiments, the controller 110 may identify the user 126, one or more articles of clothing or attire of the user 126, and cause the image sensor 120 to capture one or more images of the user 126. The controller 110 may control the camera 118 or image sensor 120 thereof to take or capture the image such that the user 126 is in view of the camera 118. In this way, the controller 110 controls the camera 118 to capture the image such that the user 126 is within the image. In one or more embodiments, the controller 110 may control panning of the camera 118, if available, motion tracking, or focus lock on the user 126 while the user 126 is walking, moving, or approaching the vehicle 100.
The camera 118 may be a Multiview camera and may include an image sensor 120 and the image processor 122. As previously discussed, the image sensor 120 may capture image color information from an image taken or captured by the camera 118. Because the controller 110 commands the camera 118 to capture images of the user 126, the image color information of such an image includes image color information associated with the user 126. According to one aspect, the camera 118 may take a color cue from the driver's attire or the passenger's attire.
The image processor 122 may extract image color information associated with the user from the image. In one or more embodiments, the processor 112 or the image processor 122 may identify one or more articles of clothing of the user and extract respective image color information associated therewith. In other words, the image processor 122 may extract image color information associated with an article of clothing of the user 126 based on the image captured by the image sensor 120. When the user 126 is wearing multiple articles of clothing or accessories or other attire, the image processor 122 may determine and extract one or more sets of image color information (e.g., primary image color information, secondary image color information, tertiary image color information, predominant image color information, etc.). Whether a color is primary, secondary, tertiary, etc. may be based on an amount of two-dimensional area that color occupies in the image. A predominant color may be defined as occupying a predetermined percentage or greater or associated with a predetermined area ratio (e.g., 2:1 of the 2-D area), etc. In this way, the image processor 122 may determine a color associated with the user 126.
The image processor 122 may create red, green, blue (RGB) color values associated with one or more sets of the image color information. In other words, the image processor 122 may create one or more RGB color values indicative of a color associated with the article of clothing of the user 126 or a color associated with the user 126. As a result, the image processor 122 may create RGB color values for a predominant color, a primary color, a secondary color, a tertiary color, etc.
The processor 112 or the controller 110 may generate a light emitting diode (LED) activation scheme based on one or more of the RGB color values associated with the user (or the user's attire, clothing, or accessories). According to one aspect, different lighting systems of 160, 170, and 180 may be provided with different LED activation schemes. In other words, depending on the number of articles of clothing the user is wearing or the number of lighting systems 160, 170, 180 installed in the vehicle 100, a mode of the system 102, etc., any number of LED activation schemes may be generated. For example, if the vehicle 100 includes two lighting systems 160 and 170, the processor 112 may merely generate two (e.g., a first and a second) LED activation schemes based on the color of the user's shirt and pants, respectively. Alternatively, if the system 102 is in an ambient mode, the processor 112 may generate a single LED activation scheme based on the predominant color detected in the image. In other modes, the processor 112 may generate additional schemes (which may be implemented at different points in time), for example. The LED activation schemes may correspond to one or more of the colors described above (e.g., predominant color, primary color, secondary color, tertiary color, etc.) or may interweave one or more of these colors at different points in time, phasing in and out among different LED activation schemes, similarly to a screen-saver.
As a result, the first LED driver 106a may activate portions of the first plurality of RGB LEDs 104a based on the first LED activation scheme, thereby causing the first plurality of RGB LEDs 104a to exhibit or produce a color according to the corresponding LED activation scheme (e.g., which may be the user's shirt color) or otherwise produce personalized vehicle ambient lighting having a color matching the color associated with the user 126 (or associated article of clothing). According to the example where the processor 112 generates two LED activation schemes (based on the color of the user's shirt and pants), the second LED driver 106b may activate portions of the second plurality of RGB LEDs 104b, which causes these LEDs to produce the secondary color (e.g., which may be the user's pants color).
According to one aspect, the camera 118 may take a color cue based on a time of day, weather report, climate determination, outside temperature, etc. when image color information associated with the user is unavailable. This may occur for a variety of different reasons. For example, if the camera 118 or the image sensor 120 malfunctions, the image is out of focus, the image is captured without the user 126 in the image, an obstacle is in the way (e.g., a bird flies in between the camera 118 and the user 126 during image capture), then image color information associated with the user would be unavailable. The image processor 122 or the processor 112 may use object recognition algorithms or software to detect whether the user 126 is captured within the image. If it is determined that the image color information associated with the user is unavailable, the processor 112 may generate the LED activation scheme based on one or more alternatives.
According to one aspect, the camera 118 may take a color cue based on a predetermined profile, a predetermined theme, or a predetermined color palette when color information is unavailable. This information may be obtained from the memory 114 of the controller 110 or from the telematics unit 150 and passed to the controller 110. According to another aspect, the processor 112 may generate the LED activation scheme based on a profile associated with the key fob, a time of day, a weather report, a predetermined color palette, or randomly when image color information associated with the user is unavailable. This information may be obtained from the telematics unit 150 via a telematics channel. The profile information or the predetermined color palette may be stored on the memory 114, while the time of day or weather report may be received via the telematics unit 150. As such, when it is cloudy, for example, the LED activation scheme may cause one of the sets of RGB LEDs 104a, 104b, or 104c to produce a grey color (e.g., thereby matching the color of the clouds). Further, the LED activation scheme may be tuned based on the intensity of the weather (e.g., if it is windy or more rainy, change colors, intensity, pulse of the RGB LEDs 104a, 104b, or 104c based on the intensity thereof).
In other embodiments, the LED activation scheme may be updated on a continual basis or be based on a speed at which the user 126 is walking or a distance between the user 126 and the vehicle 100. For example, the LED activation scheme may include an adjustment to a brightness, an intensity, or a duration of activation based on a proximity of the user 126 to the vehicle 100. In this example, the RGB LEDs 104a, 104b, or 104c may be illuminated brighter or more intensely as the user 126 approaches the vehicle 100 more closely. As another example, the LED activation scheme may include an adjustment to a brightness, an intensity, or a duration of activation based on the speed of the user or a walking pattern for the user. In this example, the RGB LEDs 104a, 104b, or 104c may be illuminated brighter or more intensely as the user 126 takes each step so that the LEDs pulse as the user 126 walks.
FIG. 4 illustrates a method 400 of personalized vehicle ambient lighting on a vehicle. At 402, the method 400 includes detecting a user approaching a vehicle. As previously discussed, a variety of implementations or embodiments having different sensor types may be used. At 404, an image of the user is captured. A controller may enable target tracking, focus lock, or panning of a camera so that the user is the primary focus or target in the image captured. At 406, a color associated with the user is determined and at 408, corresponding RGB color values are generated or created. These RGB color values are used to generate an LED activation scheme for one or more lighting systems of a vehicle at 410. At 412, the RGB LEDs are activated according to the LED activation scheme.
