Description

A headlight system for achieving dynamic light control and method thereof

The field of invention generally relates to headlights. More specifically, it relates to a headlight and a method for controlling brightness, pitch and focus of the light dynamically over a wide range with multiple light beam control.

Automotive headlights usually have a housing with a light exit opening, which is covered by a transparent cover glass or plastic. The headlight is arranged with at least one light reflector for generating one or more desired light distributions. The light reflector has at least one light source in the form of an incandescent lamp, gas discharge lamp or at least one semiconductor light source. The light emanating from the light source is reflected by the light reflecting module onto the road path in front of the vehicle to produce a desired light distribution.

The existing automotive headlights usually have only two different beam settings, namely a high beam, and a low beam. The two types of beams do not provide any form of control over the wide spread of the light to sideways, brightness as well as pitch of the light over a dynamic range.

Further, the existing automotive headlights are designed with light control systems, where multiple light sources are controlled to increase brightness and pitch of the light based on different parameters like obstacles, weather etc. However, such systems consume more power and are not efficient in providing accurate light focus based on the different parameters.

Thus, in light of the above discussion, it is implied that there is a need for an automotive headlight system that provides dynamic light control and does not suffer from the problems discussed above.

Object of Invention

The principal object of this invention is to provide a headlight system for achieving dynamic light control over a wide range with automatic control over pitch, focus angles, and brightness of the emitted light using swivel light focusing components.

Another object of the invention is to provide a headlight matrix system that provides multiple beam control from minimum to maximum light emission.

A further object of the invention is to provide a headlight matrix with intelligent light control that controls the emission of light and ensures the safety and better-focused visibility.

Another object of the invention is to achieve enhanced light control of a matrix of lights with less power consumption.

This invention is illustrated in the accompanying drawings, throughout which, like reference letters indicate corresponding parts in the various figures.

depicts a headlight 100 comprising a matrix of light sources and light focusing components. The headlight 100 comprises multiple light sources 104 which are arranged in a matrix configuration, in a housing 102. Each light source 104 is attached to a swivel light focusing component 106.

In an embodiment, each light focusing component 106 is controlled to achieve swivel movement in multiple axes so that different beams of light with variable focus and pitch can be achieved. The swivel light focusing component 106 may comprise at least one of, but not limited to swivel reflectors, collimator lenses, mirror components, projector lens, and other forms of light focusing components.

In an embodiment, the light source 104 may comprise at least one of, but not limited to light emitting diodes, halogen lamps, laser projectors and xenon HID lamps.

The matrix configuration of light sources 104 comprising individual swivel movement of multiple light focusing components 106 provides superior control over pitch, focus angles, and brightness of the light emitted by the headlight 100. Through the proposed headlight 100 design, dynamic lighting control can be achieved by controlling the light focusing components 106 individually based on external parameters and application parameters. In case the headlight 100 is used in an automotive, vehicle parameters such as speed, turns, tilts, and other external parameters such as slopes, weather, and obstacles.

In an embodiment, an intelligence algorithm may be implemented to select any desired light focusing component 106, and control/implement a required moving axis and brightness to achieve the required light control. This leads to low power consumption since only selected light focusing components 106 are controlled at a given point of time and the rest are turned OFF.

In an embodiment, the intelligence algorithm may receive one or more input parameters from one or more of: a user, various on-board-controllers, or user devices connected to the automotive or vehicle. The received input parameters are then analyzed to control the selected light focusing components 106 to control the overall brightness, focus angles and pitch of the headlight 100.

In an embodiment, the intelligence algorithm may be implemented within a headlight controller through which the light focusing components 106 can be automatically controlled. Further, the intelligence algorithm may comprise an Artificial Intelligence algorithm.

depicts a single light source arrangement 200 comprised within the matrix configuration depicted in . The single light source arrangement 200 comprises the light source 104 with its light focusing component 106 and multiple actuators 108/1, 108/2. The actuators 108/1, 108/2 are connected to the light focusing component 106. Although the light focusing component 106 is depicted with two actuators 108/1, 108/2, multiple actuators 108 may be employed to control the movement of the light focusing component 106 in various axes.

The actuators 108/1, 108/2 are selectively controlled by the headlight controller based on one or more input parameters received such as vehicle parameters and other external parameters. The light focusing components 106 may be connected to multiple actuators 108 instead of two actuators 108/1, 108/2 for controlling the movement of light focusing components 106 in multiple axes, to achieve multiple beam control and variable focus and pitch of the emitted light.

In an embodiment, the headlight 100 may be provided with customized settings according to user requirements, by providing user input with manual controls such as knobs, joystick, among others. Additionally, the user inputs for the headlight 100 may also be obtained from a user device that may be connected to the automotive or vehicle. The user device may comprise at least one of a smartphone, a smart watch, a laptop, a tablet, and any other portable electronic device. Further, each user may enter pre-set parameters for the headlight 100 such as light parameters, user parameters, weather parameters etc.

In an embodiment, the light parameters comprise at least one of focus angle, pitch and brightness of the headlight 100.

In an embodiment, the user parameters comprise at least one of rider’s height settings, rider’s seat height and handle tilt preferences.

In an embodiment, the weather parameters comprise weather related data.

depicts a flow diagram 300 for controlling light focusing components.

In an embodiment, the headlight is connected to the headlight controller. As depicted at step 302, the input parameters such as focus angles, brightness, vehicles speed, weather, road path, among others which are required to control the brightness, focus angles and pitch of the headlight are obtained from the user or from various onboard controllers according to the current lighting scenarios. The input parameters are obtained by the headlight controller.

Subsequently, the received input parameters are processed as per the lighting conditions by the headlight controller, as depicted at step 304. Thereafter, the headlight controller sends control signals to the required actuators based on the processed input parameters as depicted at step 306. Thereafter, the multiple actuators receive the control signals from the headlight controller and control movement of the required light focusing components 106, as depicted at step 308.

depicts a schematic view 400 of a dynamic light control of vehicle headlight 100 based on rider height.

In an embodiment, the proposed headlight 100 is employed in two wheeled vehicles to achieve rider height based dynamic lighting. As per the figure, two cases with different rider heights are depicted. In Case 1, a shorter rider 402 with a viewable downward angle 404 and an angle 406 at which light is pitched downward using the proposed headlight 100, is depicted. In Case 2, a taller rider 408 with a viewable downward angle 410 and an angle 412 at which light is pitched downward using the proposed headlight 100 is depicted.

From the figure, the taller rider 408 has a greater downward viewable angle 410 compared to the shorter rider 402. Using this data, the angle at which light is focused downward is controlled by the headlight controller. Thus, the near pitch of the headlights are controlled using this design, by obtaining the rider height details and calculating the required focus angles using an algorithm.

In an embodiment, the rider height may be obtained from one or more of embedded on-board cameras, user devices, cloud server, or from any other form of input of rider height. In an embodiment, the rider height data may be obtained through an embedded camera facing the rider, or by using user-defined data obtained through the user device which is connected via Bluetooth. Further, the rider height may be predicted by considering seat height data.

The rider's height is predicted by correlating the seat height settings that the rider is using. In an embodiment, the rider's height is directly proportional to seat height adjustment level. Therefore, the rider height is obtained by multiplying ‘k’ with seat height level, where 'k' is a proportionality constant. Further, this proportionality constant is unique to different vehicles and the same shall be derived by obtaining a dataset of rider and seat height settings for the specific vehicle and then calibrating the parameter 'k' value. The accuracy of the same shall be enhanced by using larger datasets.

depicts a method 500 for calculating angle of light based on rider height. The method 500 begins with step 502, where the headlight controller starts the rider height processing when the vehicle is turned ON using an algorithm. Thereafter, the rider height is obtained from cloud server or directly from the user device, as depicted at step 504, where the user preferences are set.

As depicted at step 506, verification is done to determine whether the rider height data is obtained and available. Later, the focus angle at which illumination suits the best for the rider height is calculated, as depicted at step 508, in case the rider height data is available. The headlight controller obtains the rider height data from the on board camera or from seat height settings, as depicted at step 510, in case the rider height data is not available. Thereafter, the process continues to step 508 of calculating a focus angle at which illumination suits the best to the obtained rider height data from the step 510.

The calculated focus angles are sent to the headlight controller over CAN bus, as depicted at step 512. Subsequently, current height data of the rider is obtained repeatedly for a set period of time in real time, as depicted at step 514. As depicted at step 516, verification is done for identifying changes in the rider height. The process of obtaining the current height data of the rider is continued at step 514, in case no change is observed in rider height. In case if there is a change in the rider height data, then process of calculating the focus angle of the headlight is carried out at step 508.

depicts a method 600 for dynamically controlling the brightness, pitch and spread of the headlight based on weather data by the headlight controller.

As depicted at step 602, the method starts when the vehicle ignition is started. The weather data is obtained either from available GPS data or from the user device, as depicted at step 604. Subsequently, the environmental condition data is obtained from onboard environment sensors, as depicted at step 606. At step 608, verification is done to determine whether weather data and environmental condition data are obtained from both sources.

Later, both the weather data and environmental condition data are compared, as depicted at step 610, in case data is available from both the sources. Otherwise, the decision regarding fog lights and the required brightness of the headlight or LEDs is determined based on the single source obtained, as depicted at step 612. If no data is obtained from both the sources, a default lighting state or manual light setting is continued, as depicted at step 614.

After the comparison at step 610, verification is done to determine whether the compared data is conflicting, as depicted at step 616. If the data is not conflicting, a decision regarding fog lights and required brightness of the headlight or LEDs is automatically determined, as depicted at step 618. If the data is conflicting, the onboard sensor data is prioritized, as depicted at step 620, and then the decision making for the headlight is carried out as depicted at step 618.

The data from

steps

612, 614, and 616 are sent to the headlight controller over CAN bus for the calculation and is also shared when there is a change in weather and environmental condition data, as depicted at step 622. The process further repeats from step 604. Thus, the combination of data obtained from GPS based real-time weather and on-board sensors that sense the environment is used to control the brightness of headlights and also use the fog lamps when necessary.

The CAN (Controller Area Network) is a network of nodes that facilitates communication between two or more nodes or controllers. It is a protocol for data transfer that is error resistant and real-time capable, hence is used in automobile for critical applications.

In an embodiment, since the headlight control data is very time-sensitive, the same shall be sent through the CAN bus to achieve a faster and efficient data transfer.

In an embodiment, the pitch, height and focus angles of the light focusing components 106 may be dynamically changed when the automotive or vehicle undergoes turns, tilts or executes any inclinations or declinations. The change in slopes may be obtained through gyroscopes, turn sensors or any other forms of inputs that inform regarding the turns, tilts or executes any inclinations or declinations.

As an example, when a vehicle is executing a turn, a large area on the opposite side of the turn is left un-illuminated which can lead to unprecedented accidents or issues. Therefore, when the vehicle tilts, the tilt angle by which the handle turns is obtained from the gyroscope and the lighting is compensated for the dark spots, by illuminating a one or more additional angle of area which is equal to the turning to ensure better visibility.

The tilt input of the vehicle is communicated to the headlight controller from the gyroscope. The headlight controller processes the received information comprising vehicle tilt input by using Artificial Intelligence algorithms. Thereafter, control signals from the headlight controller are transmitted to desired actuators 108 to in turn control the required light focusing components 106 and their axes.

depicts scenarios 700 with a vehicle 702 without tilt and a tilted vehicle 706. The vehicle 702 without tilt is depicted with headlight 100 which emits light covering a normal range area 704 (depicted in white dashed lines). The vehicle 706 is tilted to right in this scenario. The tilted vehicle 706 is depicted with headlight 100 which emits light covering additional area 708 (depicted in black dashed lines) along with the normal range area 704.

Thus, the proposed headlight 100 covers additional area for illumination of the tilted vehicle 706 by controlling the light focusing components 106, when compared to the vehicle 702 with no tilt.

depicts scenarios 800 with a vehicle moving straight 802 and a vehicle turning right 806.

The vehicle moving straight 802 is depicted with headlight 100 which emits light covering a normal range area 804 (depicted in white dashed lines). The vehicle 806 is turned to right in this scenario. The turned vehicle 806 is depicted with headlight 100 which emits light covering additional area 808 (depicted in black dashed lines) along with the normal range area 804.

From the figure, it is observed that a large area to the left gets dark when the vehicle is turned to right. Thus, the proposed headlight 100 illuminates additional degrees of light to the left by controlling the light focusing components 106, and the darkness due to turns is thus compensated.

depicts scenario 900 with adjustment of focus angle of the headlight 100 for different road conditions.

When the vehicle is on a slope which has an inclination or declination, the focus of the light is shifted, which reduces the visibility of a corresponding farther or nearer area. Therefore, the proposed headlight controller receives the angle of inclination and compensates for the darkness of the nearer area, by illuminating additional degrees of light downward.

Similarly, on declinations and potholes, etc., the proposed headlight controller receives the angle of declination and other parameters and compensates for the far field illumination, by illuminating additional degrees of light upward.

depicts a method 1000 for dynamically controlling the brightness, pitch and spread of the headlight based on slope data by the headlight controller.

As depicted at step 1002, the method starts when the vehicle ignition is started. Thereafter, data regarding turns and slopes are obtained from GPS, as depicted at step 1004. Subsequently, inclination data from gyroscopes are obtained, as depicted at step 1006. Later, verification is done for identifying any change inclination of the vehicle, as depicted at step 1008.

The calculation of the angle of sideward inclination is carried out at step 1010 to decide the focus and height of left or right swivel light focusing components, in case there is a sideward inclination. If there is no change in the inclination, the method repeats from step 1004.

If there is an upward or downward slope experienced by the vehicle, the upward or downward focusing of the headlight are calculated to control depending on the angles of the upward or downward slopes, as depicted at step 1012. The calculated data is sent to the headlight controller via CAN bus when there is a change from previous data, as depicted at step 1014, and the method repeats from step 1004.

depicts scenarios 1100 with variations in light emission at various vehicle speeds. In an embodiment, the controller of the headlight 100 controls pitch of the headlight 100 based on the speed data received from the vehicle. At lower speeds (speed < “p” kmph), the pitch of the light is generally lower unless there are obstacles ahead. At higher speeds (speed > “q” kmph), the pitch is also higher since farther objects have to be made visible. At moderate speed (“p” kmph < speed < “q” kmph), the pitch is controlled at a moderate level.

As depicted in the figure, the spread of the emitted light is also controlled based on the speed of the vehicle. The spread of the emitted light decreases with the speed of the vehicle.

depicts a method 1200 for dynamically controlling the brightness, pitch and spread of the headlight based on vehicle speed to ensure safety and better focused visibility. The method 1200 begins when the vehicle ignition is started at step 1202. Subsequently, the current speed from speed sensor at vehicle wheel is obtained, as depicted at step 1204. Thereafter, verification is done to check the speed criterion which is previously set, as depicted at step 1206.

The headlight is controlled for higher spread of light emission at sideways and pitch at shorter distance (“X” m), as depicted at step 1208, in case the speed < p kmph. In an embodiment, the speed data may be obtained from a wheel speed sensor, on-board radar, GPS or other sensors that sense the speed of the vehicle. The headlight is controlled for lower spread of light emission at sideways and pitch at long distance (“X+Z” m), as depicted at step 1210, in case the speed > q kmph.

The headlight is controlled for medium spread of light emission at sideways and pitch at medium distance (“X+Y” m), as depicted at step 1212, in case p kmph < speed < q kmph. The light spread data and pitch data at different speeds are sent to the headlight controller via CAN bus as depicted at step 1214. The method 1200 is repeated from step 1204.

depicts a scenario 1300 with obstacle highlighting.

In an embodiment, the headlight controller utilizes a unique combinational system structure comprising cloud-based database and on-board cameras with Artificial Intelligence. The headlight controller warns the rider regarding obstacles and also highlights such obstacles by controlling the pitch and focus of headlight 100 without dazzling the opposite vehicle riders, as depicted in the figure.

The obstacles may comprise humps, potholes, blocks/barricades etc. The data regarding irregularities on the road may be updated regularly by one or more cameras on all vehicles. In an embodiment, there may be obstacles like animals and pedestrians that can cross the road and cause accidents/be hazardous to the rider. The headlight controller may utilize one or more AI based cameras to detect such obstacles and highlight the obstacles with one or more additional beams.

In an embodiment, a cloud-based system may be utilized to maintain a database of potholes, humps and other obstacles that may cause potential issues while driving. The automotive or vehicle may update the database whenever such obstacles are detected through camera based image processing. The database may be updated if the previously known obstacles are now missing or if the potholes have been closed etc. In addition to camera based sensing, pressure sensors at suspension also detect obstacles like bumps, so that the data may be validated.

During the night, if an already known obstacle is on the rider’s path, the emitted light will be made to focus on the detected obstacle to warn the rider a few handy seconds before the rider can notice the detected obstacle.

depicts a method 1400 for highlighting the obstacles using the headlight. The method 1400 begins with obtaining obstacles on riding path from one or more on-board cameras and cloud-based database, as depicted at step 1402. Subsequently, the obstacles are processed by using Artificial Intelligence algorithms, as depicted at step 1404. Thereafter, the rider is warned with a warning light which is displayed when any obstacle is determined to be on the rider’s path, as depicted at step 1406.

Later, brightness, pitch and spread of the headlights are controlled to highlight the obstacles based on vehicle speed, as depicted at step 1408. The obstacles are highlighted only if they are within a certain distance from the vehicle, to avoid higher beams being used for farther distances. Next, data regarding irregularities on the road are updated regularly by cameras on all the vehicles, as depicted at step 1410.

depicts a method 1500 for controlling the movement of the headlight. The method 1500 begins with providing one or more light sources within a housing, as depicted at step 1502. Subsequently, the method discloses connecting a swivel light focusing component to each of the one or more light sources, wherein the swivel light focusing component is configured to allow each light source to move in multiple axes to achieve different beams of light with variable focus, and pitch, as depicted at step 1504. Thereafter, the method discloses providing a headlight controller operatively connected to the headlight , wherein the headlight controller is configured to receive input from an input provider and process the received input to control movement of at least one light source based on processed input, as depicted at step 1506.

The advantages of the current invention comprise an automotive headlight matrix system and method to achieve dynamic light control over wide range. The headlight provides automatic control over pitch, focus angles and brightness. The headlight provides multiple beam control from minimum to maximum light emission.

The headlight matrix further facilitates an intelligent light control system that controls emission of light, and ensures safety and better focused visibility. The headlight illumination may be controlled to achieve enhanced light control of a matrix of lights with less power consumption. Thus, the proposed design is useful and easily upgradable with available applications.

Applications of the current invention comprise automotive headlights, and other lighting applications where the light focus, brightness and pitch can be controlled based on different parameters such as weather, obstacles, environmental conditions etc.
