Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the priority under 35 U.S.C. §119 of India application no. 1227/DEL/2015, filed May 2, 2015, the contents of which are incorporated by reference herein. 
         [0002]    The present specification relates to adaptive lighting. 
         [0003]    Automotive vehicles can include a variety of different lamps to provide illumination under different operating conditions. Headlamps can be controlled to alternately generate low-beams and high-beams. Low-beams provide less illumination and are used at night to illuminate the forward path when other vehicles are present. High-beams provide significantly more light and are used to illuminate the vehicle&#39;s forward path when other vehicles are not present. 
         [0004]    Driving at night is usually more dangerous than driving during the day. Pedestrians and cyclists on the roads are especially at high risk due to the limited visibility of motorists at night. This raises the importance of maximizing a driver&#39;s forward vision for night-time driving safety purpose. Drivers need to look as far ahead as possible for traffic signs, road geometry, other vehicles, pedestrians and potential hazards. 
         [0005]    Also, car accident data shows that the rate of night time accidents is higher than that of day-time. This fact may be due to a number of factors, such as poor lighting condition at night that reduces the visual capability of the driver against hard to detect such as pedestrians, animals, and cyclists. At night it is very difficult to determine the nature of foreign objects by human eye from long distance under poorly lit conditions. Always run in high-beam position mode may be thought as a temporary solution to the problem described above. However this will be result in higher power consumptions as well as heating of the light assembly. 
         [0006]    High-beams provide significantly more light and are used to illuminate the vehicle&#39;s forward path when other vehicles are not present. Since high-beams provide significantly more illumination of the forward path, it is always desirable to drive with high-beam on for a better road visibility to the driver. However this high intensity light beam can create a high-beam glare to an oncoming vehicle and may result in an accident. Similarly high-beam glare from a preceding vehicle is also a major contributor to the accidents. In both case the vehicle high-beam can momentarily ‘dazzle’ other road users and contribute to accidents. 
         [0007]    Another critical problem with the traditional high-beam vehicle light is that, drivers usually do not turn the high-beams on or off when needed and instead, keep the headlights on in high-beam position in order to avoid frequent switching and often forget to dim the headlight in the face of oncoming or preceding traffic. This also can dazzle other road users and contribute to accidents. Alternatively remaining in low-beam illumination reduces the driver&#39;s visibility range and the ability to identify and respond to hazards ahead. 
         [0008]    An adaptive head-light control could help address some of these concerns. Such adaptive systems can be based on a illumination based sensor for detecting the vehicle in front. Camera based solutions are also possible, where in a camera is used for detecting and classifying the type of vehicles in front and controlling the low/high-beam nature of the head-light. Alternatively, a simple CMOS light sensor can also be used to detect the existence of the vehicle in front.

       [0040]    While the disclosure is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that other embodiments, beyond the particular embodiments described, are possible as well. All modifications, equivalents, and alternative embodiments falling within the spirit and scope of the appended claims are covered as well. 
       DETAILED DESCRIPTION 
       [0041]    The adaptive head-light control systems discussed above may not: operate optimally under bad weather conditions; enable precise control of the head-light beam; enable tracking of oncoming vehicles. Some such systems can only detect an incoming vehicle if its head-lights are on. Other such systems cannot detect other types of foreign objects reliably (for example pedestrians, animals, cyclists, etc.). 
         [0042]    An improved adaptive head-light solution would take care of the following situations:
       Selective blinding/dimming of the head-light towards an incoming vehicle to enhance the visibility of the incoming vehicle driver.   Selective enhancement of head-light beam illumination on hard to detect foreign objects, especially in poor visibility conditions.   Tracking capability to steer the light beam to selected (multiple targets) targets stated in (1) and (2) above.       
 
         [0046]    In example embodiments discussed below, an adaptive lighting apparatus is discussed. In one set of example embodiments, the adaptive lighting apparatus is used with a vehicle having a radar sensor, LED lighting arrays a laser based head-light. The example apparatus could include an automotive high-beam control (HBC) module using car radar sensors along with a camera sensor to detect and classify foreign objects in terms of their type, range, relative velocity as well as their angle in front of a vehicle during night driving condition and then automatically adjust the head-light beam pattern using arrays of LED and laser diode based head-light assembly. Equipped vehicles can adjust the light beam angle and elevation plus the beam intensity to selectively illuminate the foreign object. 
         [0047]    The apparatus in various embodiments could automatically track and adjust the beam pattern on a continuous manner when it detects multiple foreign objects in front. If the detected foreign object is an oncoming vehicle, then the light intensity will be reduced. In case of other hard to detect foreign objects light intensity can be increased. The apparatus can also switches the headlights to low-beam when the vehicle is driving in brightly lit urban areas or at lower speed by providing additional light sensor input and a speed sensor input. 
         [0048]    In another embodiment, the adaptive lighting apparatus is used with a vehicle having conventional halogen/incandescent head-lights. Such conventional lighting based embodiments may limited to either switching between high and low-beam light or include a mechanical assembly for steering the conventional light. 
         [0049]    Such embodiments, introduced above, can include always keeping the head-light at a high-beam/intensity level for maximum driver visibility, except when dimming is needed to avoid dazzling (e.g. presenting glare to) another driver. 
         [0050]      FIG. 1  is an example adaptive lighting apparatus  100 . The example lighting apparatus  100  includes: a radar sensor  102 , a camera sensor  104 , additional sensors or information  106 , a control unit  108  having an attribution module  128  and a lighting module  130 , a first lighting source  110  (e.g. Low-beam) having a driver  112  and lighting array  114 , a second lighting source  116  (e.g. High-beam) having a driver  118  and a lighting array  120 , and a third lighting source  122  (e.g. Laser Light) having a driver  124  and a lighting array  126 . 
         [0051]    The radar sensor  102  in one example embodiment can be mounted to the front of an automotive vehicle so as to better detect other vehicles, people, road conditions, animals and so on in the path of the vehicle. More generally the radar sensor  102  is attached to a parent object (e.g. an automotive vehicle) an optimal location so as to better detect foreign objects (e.g. other vehicles, people, road conditions, animals and so on). The parent object is herein defined as any structure which includes the apparatus, systems, devices and functionality herein discussed. Foreign object are herein defined as any object or condition with which the parent object is designed to detect. In other example embodiments, more than one radar sensor  102  can be attached to the parent object. 
         [0052]    The radar sensor  102  can provide the following information with respect to foreign objects in proximity to the parent object: angle of the foreign object with respect to the parent object; range between the parent object and the foreign object; relative velocity between the parent object and foreign objects; and a radar signature (i.e. radar cross-section (RCS)). 
         [0053]    As will be discussed further below, the radar signature from the radar sensor  102  is used by modules in the control unit  108  to classify the foreign object (e.g. use a best-match routine to label the foreign object as either: a car, a truck, an animal, a wet road, a dry road, a pothole, a tree, a road edge, a road sign, a road marking, rain, snow, fog, ice, and so on). 
         [0054]    In various embodiments, the radar sensor  102  operates in the 76-81 GHz range and is capable of capturing a 20 MHz bandwidth radar signature. 
         [0055]    The camera sensor  104  in one example embodiment is used by modules in the control unit  108  to aid in classification of the foreign object. For example the camera sensor  104  can determine whether the foreign object is self-illuminated (e.g. has headlights on and is thus likely a vehicle) or not self-illuminated (e.g. could be a person, a natural object or an animal). the camera sensor  104  can also be used to measure an intensity of the entire foreign object and based on the information modify how the control unit  108  commands the lighting sources  110 ,  116 ,  122  to dynamically illuminate the foreign object. 
         [0056]    The additional sensors or information  106  can include: an ambient light sensor; a humidity sensor; a temperature sensor; and a set of parent object attributes. In the case where the parent object is an automotive vehicle, the set of parent object attributes can be obtained from the vehicle&#39;s ADAS (Advanced Driver Assistance Systems). The ADAS information includes a variety of sensory information, including the vehicle&#39;s speed. Knowledge of the parent object&#39;s ambient lighting environment can be used by the control unit  108  to determine if it&#39;s daytime or nighttime, or perhaps if the parent object is itself illuminated by a street light. 
         [0057]    The lighting sources  110 ,  116 ,  122  can be any combination of an LED array, a laser diode array, an incandescent bulb, and so on. An LED array light source includes individual LED elements which can be positioned in various directions and varied in beam intensity (i.e. lumen output) to produce and steer a light source beam pattern in both azimuth and elevation. Such an array in one example can be selectively dimmed towards an incoming car and alternately brightened toward an unlit person next to the road. 
         [0058]    Laser diode arrays have similar directional and intensity characteristics and can be used to steer multiple beams in both azimuth and elevation to illuminate hard to detect foreign objects. Even incandescent bulbs can be selectively dimmed and brightened in response to commands from the control unit  108 . 
         [0059]    The control unit  108  includes the attribution module  128  and the lighting module  130 . The attribution module  128  inputs data signals from the radar sensor  102 , the camera sensor  104 , and any additional sensors or information  106 . The attribution module  128  either minimally processes (e.g. angle and range information from the radar sensor  102 ) or significantly processes (e.g. foreign object classification from the radar signatures) these inputs. 
         [0060]    For the minimally processed information, such as angle and range information, the attribution module  128  can pass such information to the lighting module  130  for eventual steering and beam intensity modulation of the lighting sources  110 ,  116 ,  122 . 
         [0061]    However for the significantly processed information, the attribution module  128  compares one or more radar signatures received from the radar sensor  102  to a library of stored radar signatures in order to classify the one or more foreign objects before a final set of steering and beam intensity modulation commands are sent to the lighting sources  110 ,  116 ,  122 . 
         [0062]    The library of stored radar signatures in various embodiments includes pre-classified objects having radar signatures for such as: a set of vehicles (e.g. car, truck, bicycle, etc.), a set of road conditions (e.g. wet, dry, icy, oily, paved road, dirt road, etc.), a set of environmental conditions (e.g. dry, raining, snowing, foggy, etc.) and a set of other foreign objects (e.g. people, animals, plants, trees, rocks, potholes, a road edge, a road sign, etc.). 
         [0063]    The attribution module  128  then uses a best match algorithm to classify the radar signature from the radar sensor  102  as corresponding to a pre-classified foreign object whose radar signature best matches the radar signature from the radar sensor  102 . The supplement, or verify, the radar signature classification, the attribution module  128  processes the camera sensor  104  input data, using image processing techniques, to classify the foreign object. The attribution module  128  can also use the camera sensor  104  input data to determine if the foreign object is self-illuminated or not. Self-illuminated foreign object tend to be oncoming vehicles, whereas objects that are not self-illuminated (e.g. are hard-to-detect) tend to be people, animals or obstructions of some sort. 
         [0064]    The attribution module  128  processes the input signals from the radar sensor  102 , the camera sensor  104 , and any additional sensors or information  106  in a dynamic way that enables foreign objects to be tracked as they move with respect to the parent object (e.g. parent vehicle). 
         [0065]    As will be discussed below, the lighting module  130  uses the foreign object&#39;s classification to steer and vary the beam intensity of the lighting sources  110 ,  116 ,  122  so as to provide, in one example, the driver of a vehicle (i.e. the parent object) as clear a view of the road ahead, without blinding passing vehicle drivers. 
         [0066]    The control unit  108  also includes the lighting module  130 . The lighting module  130  inputs data signals (e.g. angle, range and classification information) from the attribution module  128 . The lighting module  130  then outputs signals to the lighting sources  110 ,  116 ,  122  based on these inputs. These output signals control the beam/element intensity for each lighting source element, thereby enabling the lighting source  110 ,  116 ,  122  lumen output to be steered in angle and elevation as well as varied in brightness. 
         [0067]    Some example lighting module  130  output signal scenarios are now presented. For example, if the foreign object is another vehicle with its head-lights on, the beam intensity of lighting elements directed at the vehicle is decreased. If the foreign object is a hard to detect object such as a person walking nearby the road without any self-illumination, then the beam intensity of lighting elements directed at the person is increased. 
         [0068]    Since each of the lighting elements are independently controlled, one lighting element on one side of the parent vehicle (i.e. parent object) can be increased for hard to detect objects, while another lighting element on another side of the parent vehicle can be decreased for passing cars. The lighting elements can also be steered in elevation such that a lower portion of a passing truck is illuminated while light toward the truck&#39;s driver&#39;s cab is reduced to avoid blinding the passing truck driver. 
         [0069]    As the foreign objects are tracked by the radar sensor  102 , the lighting module  130  will correspondingly vary the beam intensity of the various lighting source  110 ,  116 ,  122  elements at least in accordance with the examples provided above so as to ensure a maximum level of parent vehicle situational awareness while minimizing blinding passing drivers. 
         [0070]    In additional example embodiments, the illumination beam intensity is a function of the range of foreign object and type/classification of the foreign object. The beam direction/pattern (azimuth and elevation) is also a function of the foreign object&#39;s angle with respect to the parent object. Higher beam illumination intensities (using laser headlight with phased array approach) can be directed upon hard to detect foreign object to improve the parent driver&#39;s visibility. 
         [0071]    Such variable beam intensity also allows the adaptive lighting apparatus  100  to be deployed in a power efficient manner, primarily due to the fact that the power consuming high-beams, in one example embodiment, are steered only towards detection of hard to detect foreign objects than a blind high-beam. 
         [0072]    Another alternate embodiment of the adaptive lighting apparatus includes a day-time algorithm, a low-speed algorithm and a high-speed algorithm. 
         [0073]    In one example of the day-time processing algorithm, during day-time when the parent vehicle&#39;s lights are normally off, the parent vehicle&#39;s head-light can be switched back on based on if the radar sensor  102  detects an incoming vehicle approaching face to face with the parent vehicle and if the relative velocity between the vehicle is at a dangerously high level. The head-light can be flashed to give visual warning to the incoming vehicle. The flashing rate can be based on the relative velocity value (higher the relative velocity means higher the flash rate). 
         [0074]    In one example of the low-speed processing algorithm, during night time under low-speed condition, it is may not be necessary to use the high-beam light. In this case only the low-beam LED array need to be working, thus saving power. 
         [0075]    In one example of the high-speed processing algorithm, the high-beam LED array will be permanently on with selective dimming capabilities if an incoming vehicle is detected. 
         [0076]    In another example embodiment, if an incoming vehicle is coming face to face with the parent vehicle (which is especially important on two way roads) at a dangerously high-speed. In this case the head-light can be flashed to provide a visual warning to the incoming vehicle driver. 
         [0077]      FIG. 2  is an example LED lighting source  200 . The LED lighting source  200  includes an LED driver  202  under command of the lighting module  130  output signals. The LED driver  202  sends activation and power to a first LED array  204 , a second LED array  206 , a third LED array  208 , a fourth LED array  210  and a fifth LED array  212 . Each of these LED arrays contain individual LEDs. Thus the lighting module  130  output signals can individually turn each LED element on/off and vary each LED element&#39;s output power (i.e. beam intensity). This enables the LED lighting source  200  to be steered in angle and elevation and varied in output power. A similar structure could be used for a Laser diode array. 
         [0078]      FIG. 3  is an example LED lighting source beam pattern  300  from the LED lighting source  200 . The LED lighting source beam pattern  300  includes: a first LED array beam pattern  302  generated by the first LED array  204 , a second LED array beam pattern  304  generated by the second LED array  206 , a third LED array beam pattern  306  generated by the third LED array  208 , a fourth LED array beam pattern  308  generated by the fourth LED array  210 , and a fifth LED array beam pattern  310  generated by the fifth LED array  212 . 
         [0079]      FIG. 4  is an example pictorial diagram of a first operational scenario  400  involving self-illuminated foreign objects. In the first operational scenario  400  a parent object  402  (e.g. parent vehicle) is traveling behind a first foreign object  404  (e.g. a car) at an angle (a 2 ) and at a range (r 2 ). The adaptive lighting apparatus  100  keeps track of the first foreign object  404 , as discussed above, and perhaps keeps a higher beam intensity of a lower part (e.g. rear bumper and trunk) of the first foreign object  404  and a lower beam intensity on an upper part of the first foreign object  404  (e.g. corresponding to the driver&#39;s rear-view mirror). 
         [0080]    In the first operational scenario  400  the parent object  402  (e.g. parent vehicle) is also traveling past a second foreign object  406  (e.g. a car) at an angle (a 1 ) and at a range (r 1 ). The adaptive lighting apparatus  100  also keeps track of the second foreign object  406  and perhaps keeps a higher beam intensity of a lower part (e.g. front bumper and trunk) of the second foreign object  406  and a lower beam intensity on an upper part of the second foreign object  406  (e.g. corresponding to the driver&#39;s face). 
         [0081]      FIG. 5  is an example pictorial diagram of a second operational scenario  500  involving hard to detect foreign objects. In the second operational scenario  500  a parent object  502  (e.g. parent vehicle) is intersecting with a first foreign object  504  (e.g. a bicycle) at an angle (a 2 ) and at a range (r 2 ). The adaptive lighting apparatus  100  keeps track of the first foreign object  504  and perhaps keeps a higher beam intensity on all of the first foreign object  504  for maximum visibility to both the driver of the parent vehicle  502  and the bicyclist  504 . 
         [0082]    In the second operational scenario  500  the parent object  502  (e.g. parent vehicle) is also closing in on a second foreign object  506  (e.g. an animal) at an angle (a 1 ) and at a range (r 1 ). The adaptive lighting apparatus  100  keeps track of the animal  506  and perhaps not only keeps the animal  506  fully illuminated, but also directs additional light toward the animal  506  due to the animal&#39;s  506  less predictable nature. 
         [0083]      FIG. 6  is an example pictorial diagram of a third operational scenario  600  involving a mix of hard to detect and self-illuminated foreign objects. In the third operational scenario  600  a parent object  602  (e.g. parent vehicle) is passing a first foreign object  604  (e.g. an animal) at the left and a second foreign object  608  (e.g. another vehicle) on the right. Due to the unpredictability of the animal  604 , the adaptive lighting apparatus  100  directs a laser diode array beam having a first beam pattern  606  at the animal  604 . 
         [0084]    However, due to the more predictable nature of the other vehicle  608 , the adaptive lighting apparatus  100  directs a second beam pattern  610  at the vehicle  608 , where the second beam pattern  610  includes a first intensity region  612  and a second intensity region  614 . The first intensity region  612  is at a higher beam intensity for maximum visibility of the road ahead. The second intensity region  614  is at a lower beam intensity for reasonable visibility of the oncoming vehicle  608  while not blinding the oncoming vehicle&#39;s  608  driver. 
         [0085]      FIG. 7A  is an example list of instructions for enabling an adaptive lighting apparatus. The order in which the instructions are discussed does not limit the order in which other example embodiments implement the instructions. Additionally, in some embodiments the instructions are implemented concurrently. 
         [0086]    A first example instruction set begins in  702 , by receiving a set of radar data. In  704 , generating a visible illumination signal based on the set of radar data. Then in  706 , transmitting the illumination signal. 
         [0087]    The instructions above can be augmented with one or more of the following additional instructions, presented in no particular order. 
         [0088]    The additional instructions include:  708 , wherein the radar data includes a radar signature corresponding to a foreign object, classifying the foreign object based on the radar signature.  710 , setting a light source beam pattern in the illumination signal, having a beam intensity that varies in azimuth and elevation, based on the classification.  712 , directing the light source beam pattern at the foreign object.  714 , classify the foreign object by comparing the radar signature to a set of known foreign object radar signatures.  716 , classify the foreign object by comparing the radar signature to a set of known foreign object radar signatures.  718 , classify the foreign object as either self-illuminated or not self-illuminated based on the image signature.  720 , modify the visible illumination signal based on the at least one of: a set of ambient light data, a set of humidity data or a set of temperature data. 
         [0089]    While these instructions have been presented in example orders of execution, other orderings, such as discussed with respect to  FIG. 7B , are also possible. 
         [0090]      FIG. 7B  is a second example list of instructions for enabling an adaptive lighting apparatus. The order in which the instructions are discussed does not limit the order in which other example embodiments implement the instructions. 
         [0091]    In  722 , is ambient light detected (if yes go to  724 ). In  724 , activate a day-time processing algorithm if ambient light is detected. In  726 , is vehicle traveling at low-speed (if yes go to  728 . In  728 , activate a low-speed algorithm if vehicle traveling at low-speed. In  730 , activate a high-speed algorithm if vehicle not traveling at low-speed. 
         [0092]      FIG. 8  is an example system  800  for hosting instructions for enabling an adaptive lighting apparatus. The system  800  shows an input/output data  802  interface with an electronic apparatus  804 . The electronic apparatus  804  includes a processor  806 , a storage device  808 , and a non-transient machine-readable storage medium  810 . The machine-readable storage medium  810  includes instructions  812  which control how the processor  806  receives input data  802  and transforms the input data into output data  802 , using data within the storage device  808 . Example instructions  812  stored in the machine-readable storage medium  810  are discussed elsewhere in this specification. The machine-readable storage medium in an alternate example embodiment is a non-transient computer-readable storage medium. 
         [0093]    The processor (such as a central processing unit, CPU, microprocessor, application-specific integrated circuit (ASIC), etc.) controls the overall operation of the storage device (such as random access memory (RAM) for temporary data storage, read only memory (ROM) for permanent data storage, firmware, flash memory, external and internal hard-disk drives, and the like). The processor device communicates with the storage device and non-transient machine-readable storage medium using a bus and performs operations and tasks that implement one or more instructions stored in the machine-readable storage medium. The machine-readable storage medium in an alternate example embodiment is a computer-readable storage medium. 
         [0094]    The instructions and/or flowchart steps in the above Figures can be executed in any order, unless a specific order is explicitly stated. Also, those skilled in the art will recognize that while one example set of instructions/method has been discussed, the material in this specification can be combined in a variety of ways to yield other examples as well, and are to be understood within a context provided by this detailed description. 
         [0095]    In this specification, example embodiments have been presented in terms of a selected set of details. However, a person of ordinary skill in the art would understand that many other example embodiments may be practiced which include a different selected set of these details. It is intended that the following claims cover all possible example embodiments.
