Description

TITLE OF INVENTION:A CONTROL SYSTEM FOR A HEADLAMP UNIT AND A METHOD THEREOFTECHNICAL FIELD

[0001] The present disclosure relates to a control unit for a headlamp unit of a vehicle. More particularly, the present subject matter relates to a control unit and a method for controlling a headlamp unit of a vehicle.BACKGROUND

[0002] In current vehicles, lighting systems play a critical role in ensuring rider safety, and convenience but current solutions often fall short in addressing the diverse challenges faced in various driving conditions. Existing headlamp systems currently face a significant safety challenge due to their inability to adapt to changing driving conditions. Fixed headlamps do not adjust their brightness according to the rider’s speed, distance, or surrounding conditions, reducing visibility when needed most. Poor visibility due to static beam patterns not only makes it harder for vehicle operators to see the road but also reduces their visibility to other vehicles, increasing the risk of collisions.

[0003] Improved visibility in dark tunnels, shaded areas, and low-light environments is essential for providing better illumination, reducing accident risks, and enhancing user experience. However, traditional systems lack the capability to make automatic adjustments, requiring riders to manually manage settings, which can distract them from focusing on the road. This limitation becomes particularly evident in low-visibility situations, such as night-time or adverse weather, where a rider's ability to see the road or to be seen by other drivers is crucial for safety.

[0004] The fixed beam patterns of traditional headlamps are not equipped to respond to dynamic factors like road curvature or elevation changes, which can create dangerous blind spots. These blind spots increase the risk of accidents, both for the rider and for others on the road due to compromised visibility.Existing headlamp units fail to adapt to dynamic road conditions, such as sudden turns, hills, or dips, which further compromises the safety of the user of the vehicle.

[0005] Furthermore, the headlamps of such vehicles are particularly problematic in bad weather, as they fail to pierce through fog, rain, or snow effectively, leaving riders with insufficient light to navigate safely. The glare from the headlight on the operators of the oncoming vehicles poses a significant safety challenge, as it can impair their ability to see clearly and react to road conditions.

[0006] Additionally, the inability to adjust headlamp settings based on factors like time of day or vehicle speed reduces the visibility of the rider to others and limits their field of vision, increasing the likelihood of collisions. Hence, the lack of a system to control and adjust illumination from the headlamp poses a significant threat to the rider as it impairs their ability to see clearly and respond to road conditions during headlamp glares from oncoming vehicles.

[0007] Due to the lack of customizable settings, the riders are inhibited from tailoring headlamp performance as per their preferences which leads to increased strain on the battery and a detrimental effect on fuel efficiency of the vehicle. Thus, there is a need to incorporate energy-efficient solutions to minimize battery drain, especially for long journeys.

[0008] The problem associated with the lack of an adaptive lighting system leads to safety concerns for riders and other proximate riders, imbalanced visibility in low light, limited brightness control, reduced battery life, and potential electrical system failures. Therefore, there is a crucial requirement for a solution that not only addresses these challenges but also provides a system that can control and adjust illumination from the headlamp of the vehicle as per the respective varying weather and vehicle conditions without constant rider intervention.SUMMARY OF THE INVENTION

[0035] The embodiments of the present disclosure will now be described in detail with reference to an embodiment of a control system (200) and a method (300) for controlling a headlamp unit (101) of a vehicle (100) along with the accompanying drawings. However, the present disclosure is not limited to the present embodiments. The embodiments shown in Figure 1 are taken for discussion. Figure 1 illustrates a block diagram of a control system (200).

[0036] In one embodiment, the control system (200) for a headlamp unit (101) of a vehicle (100) has been disclosed. The headlamp unit (101) of the vehicle (100) provides optimal visibility in different driving conditions, with specificmodes such as a low beam of light, a high beam of light, and daytime running lights (DRL) serving distinct purposes. The low beam of light setting is used for standard nighttime driving or low-visibility conditions such as fog and rain. It provides a focused yet downward-angled beam to illuminate the road ahead without blinding oncoming drivers. In contrast, the high beam of light setting produces a more intense and far-reaching light, typically used in dark, unlit areas like highways or rural roads. High beams of light are directed straight ahead to maximize visibility but should be switched off when approaching other vehicles to prevent glare. Further, daytime running lights (DRLs) are automatically activated when the vehicle (100) is in motion during daylight hours. The daytime running lights (DRLs) enhance the visibility of the vehicle (100) to other drivers rather than to illuminate the road. Unlike low and high beams of light, the daytime running lights (DRLs) usually operate at a lower intensity and may not require manual activation, as they are controlled by the control system (200) of the vehicle (100).

[0037] In an embodiment of the present disclosure, the low beam of the headlamp unit (101) of the vehicle (100) consists of a light source, a reflector or projector lens, and a cutoff shield. The cutoff shield is essential in directing the beam downward and preventing excessive glare for oncoming traffic. The vehicle (100) may use halogen, high-intensity discharge (HID), or light emitting diode (LED) bulbs for low beams of light, with light emitting diode (LED) bulbs and high-intensity discharge (HID) offering better energy efficiency and brightness. The high beam of the headlamp unit (101) of the vehicle (100), in contrast, lacks a cutoff shield and provides maximum illumination by projecting a powerful, long-range beam of light straight ahead. The high beam of the headlamp unit (lOl)typically uses the same bulb as low beams in dual-beam headlamps, where an actuator moves the shield or changes the filament of the bulb to switch between modes. In a single-beam headlamp unit (101), separate bulbs are dedicated to low and high beams. The daytime running light (DRL) uses a different setup, often integrated into the headlamp unit (101) or as a separate lighting element. The daytime running lights (DRLs) typically rely onLED technology due to their low power consumption and durability, ensuring that the vehicle (100) remains visible without significantly draining battery power. Some vehicles use the same low-beam or high-beam bulbs at a reduced intensity for the daytime running lights (DRLs), controlled by a relay or resistor to lower brightness.

[0038] The control system (200) comprises a sensor module (102) and a control unit (201) to control an adaptive lighting system (ALS) of the vehicle (100). The adaptive lighting system in vehicle (100) is integrated to enhance visibility and safety while driving, especially at night or in challenging conditions. Further, an adaptive lighting system responds to key factors such as speed and ambient light levels of the vehicle (100) to control the function of the headlamp unit (101). The control unit (201) can include but is not limited to a computer processor such as a microprocessor working in conventional configurations. The control unit (201) can also be a computing device comprising a microprocessor along with memory and other electronic peripherals that help in executing the control system (200) and methods thereof. The sensor module (102) detects one or more ambient parameters (Pl, P2). The control unit (201) receives input from the sensor module (102) which corresponds to the one or more ambient parameters (Pl, P2). Thereafter, the control unit (201) determines one or more operating modes (Ml, M2, M3, M4) of the vehicle (100). Subsequently, the control unit (201) determines a current vehicle parameter of the vehicle (100). In this manner, the control unit (201) controls a plurality of configurations (Cl, C2, C3) of the headlamp unit (101) based on the one or more ambient parameters (Pl, P2), the one or more operating modes (Ml, M2, M3, M4) and the vehicle parameter of the vehicle (100). In this manner, the headlamp unit (101) offers broader illumination at lower speeds for better awareness of the surroundings and a more focused beam at higher speeds to light up the road far ahead. Additionally, the control system (200) enables a comfortable riding experience by eliminating the need for manual adjustments and ensuring that the headlamp unit (101) harmoniously adapts to weather, terrain, and other visibility conditions. This not only improves safety for the rider but also contributes to a more harmoniousinteraction with other road users, making it an essential upgrade for the control systems for the present vehicles.

[0039] According to an exemplary embodiment of the present disclosure, while the first sensing unit (102A) and the second sensing unit (102B) provide ambient data of light near the vehicle (100). By integrating additional sensors such as humidity or temperature sensors allows the control system (200) to detect specific weather conditions such as fog, rain, or snow. The control system (200) is then equipped to deploy weather-specific beam patterns, such as wider and diffused beams from the headlamp unit (101) in foggy conditions and the focused beams for a clear visibility in heavy rain.

[0040] As per one of the embodiments, the sensor module (102) detects a level of illuminance in a front region of the vehicle (100). The front region can include the general area around the headlamp unit and above a wheel of the vehicle. The level of illuminance is determined on the basis of the first ambient parameter (Pl) and the second ambient parameter (P2) which are detected by a single sensing unit. This particular embodiment is useful for entry-level vehicles. The sensor module (102) may comprise a variety of sensors such as but not limited to photodiodes, phototransistors, silicon photomultipliers (SiPM), metal-oxide-semiconductor (CMOS) light sensors, light dependent resistor (LDR), photometric sensors, multi-spectral light sensors, RGB light sensors, time-of-flight (ToF) sensors, infrared sensors with visible light filters, daytime running light (DRL) sensor, proximity sensor, levelling sensor, temperature sensor, and camera sensor. The solution of using a single sensing unit enables the control system (200) to manage the headlamp unit (101) adaptively. This further ensures that the headlamp unit (101) operates effectively in diverse conditions, improving safety and convenience for the rider while reducing the need for manual adjustments. The control system (200) relies on a single sensing unit strategically to detect both ambient light and the level of illuminance in order to differentiate between daytime, nighttime, and poor visibility conditions. In this way, the need for multiple sensing units is reduced while functionality is maintained.

[0041] The sensor module (102) comprises a first sensing unit (102A) and a second sensing unit (102B). The first sensing unit (102A) detects a first ambient parameter (Pl) of the one or more ambient parameters (Pl, P2). The first ambient parameter (Pl) is at least one of a day time and a night time. The first ambient parameter (Pl) takes the amount of natural light in the ambience into consideration. The first ambient parameter (Pl) can be further accurately detected by using data from either the vehicle control unit or the speedometer control unit (201). The control unit (201) controls a brightness of a speedometer (103) based upon the first ambient parameter (Pl). The second sensing unit (102B) detects a second ambient parameter (P2) of the one or more ambient parameters (Pl, P2). The second ambient parameter (P2) is at least one of a high illuminance and a less illuminance of an ambient light. The second ambient parameter (P2) takes into consideration the level of illuminance from the street lights and the glare received from oncoming vehicles.

[0042] The first sensing unit (102A) and the second sensing unit (102B) work in tandem to facilitate a dynamic and responsive control system (200) for the headlamp unit (101). The readings from the first sensing unit (102 A) and the second sensing unit (102B) are continuously compared against preset threshold values in the control unit (201). In case, when these threshold values are exceeded such as in the presence of intense glare from oncoming vehicles or rapidly changing ambient light conditions. Then the control system (200) adjusts the beam pattern of the headlamp unit (101). The control system (200) tailors the adjustments based on specific driving conditions by selecting one of the plurality of configurations (Cl, C2, C3).

[0043] The headlamp unit (101) comprises at least one lightning member (101 A as shown in Figure 2). The at least one lightning member (101 A) illuminates when an ignition key of the vehicle (100) is switched ‘ON’ like a daytime running lamp (DRL). The at least one lightning member (101A) also illuminates to indicate a presence of the vehicle (100) like a front position lamp (FPL). The at least one lightning member (101 A) illuminates to emit a low beam of light like a low beam LED (LB). The at least one lightning member (101 A) illuminates toemit a high beam of light like a high beam LED (HB). In a preferred embodiment, the functions of the daytime running lamp (DRL), the front position lamp (FPL), the high beam LED (HB), and the low beam LED (LB) are integrally performed by the at least one lightning member (101A). In an alternate embodiment, the functions of the daytime running lamp (DRL), the front position lamp (FPL), the high beam LED (HB), and the low beam LED (LB) are separately performed by the at least one lightning member (101 A).

[0044] According to an exemplary embodiment, the control system (200) may integrate energy-harvesting mechanisms, such as photovoltaic cells in order to reduce battery dependency. Therefore, during the day, the photovoltaic cells may use solar energy to charge the battery which is used to power the at least one lighting member (101A) for night-time and high-intensity beam operation. This advancement can make the control system (200) highly energy-efficient, particularly for electric vehicles.

[0045] Further, the plurality of configurations (Cl, C2, C3) comprises a first configuration (Cl), a second configuration (C2), and a third configuration (C3). A selection of the first configuration (Cl) illuminates the at least one lighting member (101A) when the ignition key of the vehicle (100) is switched ‘ON’. A selection of the second configuration (C2) indicates the presence of the vehicle (100) and emits the low beam of light through the at least one lightning member (101 A). Further, a selection of the third configuration (C3) indicates the presence of the vehicle (100), emits the low beam of light through the at least one lighting member (101 A) and emits the high beam of light through the at least one lighting member (101 A). Each of the plurality of configurations (Cl, C2, C3) is suited for a particular scenario which is determined on the basis of the one or more ambient parameters (Pl, P2), the one or more operating modes (Ml, M2, M3, M4) and the vehicle parameter of the vehicle (100). This ensures that an optimum amount of light is emitted from the at least one lightning member (101A) as required in that particular scenario. Thus, eliminating the need for manual adjustments and ensuring that the at least one lightning member (101A) harmoniously adapts to weather, terrain, and other visibility conditions. This notonly improves safety for the rider but also contributes to a more harmonious interaction with other road users. Since the control unit (201) enables the emission of the high beam of light by the at least one lighting member (101 A) only when it is required, the load on the battery is reduced and the fuel efficiency of the vehicle (100) is enhanced. Also, by preventing the unnecessary illumination of the high beam of light, the glare from the at least one lighting member (101A) is reduced thereby enhancing the visibility for the other road users. According to an embodiment of the present disclosure, in urban environments or during heavy traffic, the control system (200) may utilize proximity sensors to detect the distance of surrounding vehicles and pedestrians. Based on this data, the level of illumination of the high beam of light is adjusted to reduce glare for oncoming traffic or to illuminate specific zones like crosswalks, enhancing safety for vulnerable road users.

[0046] As per an embodiment, the one or more operating modes (Ml, M2, M3, M4) are selected by a rider by providing a user input through a user interface (104). The selection may be manual or automatic using at least one controller of the vehicle (100). The one or more operating modes (Ml, M2, M3, M4) comprise a first mode (Ml), a second mode (M2), a third mode (M3), and a fourth mode (M4). According to an exemplary embodiment, the control system (200) offers three customizable driving modes that are second mode (M2), the third mode (M3), and the fourth mode (M4). The second mode (M2) is a rain mode, the third mode (M3) is an urban mode and the fourth mode (M4) is a sports mode. These modes are adaptable to different road and weather conditions. These modes allow riders to select lighting settings of the headlamp unit (101) that align with their preferences and the demands of their environment, such as enhanced visibility during rain or optimized beam focus for higher-speed sport mode. If the user selects the first mode (Ml) as the selected operating mode, the control unit (201) controls an illumination of the headlamp unit (101) based upon a feedback received from the user. The control unit (201) receives the user feedback through the user interface (104). In case the control unit (201) fails to receive the user input for determining the selected operating mode, the control unit (201) controlsthe illumination of the headlamp unit (101) in the first mode (Ml). The present control system (200) is advantageous as it provides a user interface (104) for riders who are not well-versed in manually adjusting the settings of the headlamp unit (101). According to an exemplary embodiment, in order to enhance user convenience, the control system (200) may comprise gesture or voice control interfaces. The riders may adjust one or more operating modes (Ml, M2, M3, M4) or override the control system (200) simply by gesturing or speaking specific commands. For instance, a rider can say “Switch to second mode (M2)” to immediately activate weather-specific settings.

[0047] In the event of failure of the sensor module (102), the control unit (201) controls the illumination of the headlamp unit (101) in the first mode (Ml). In this manner, the control system (200) provides a fail-safe mechanism by addressing the potential electrical system failures which can compromise the safety. If any failures occur in the adaptive lighting system (ALS) of the vehicle (100), then the control system (200) redirects to the first mode (Ml) which is the manual mode.

[0048] The vehicle parameter such as a speed of the vehicle (100). The first predetermined value (VI), the second predetermined value (V2) and the third predetermined value (V3) are the speed of the vehicle (100). The second predetermined value (V2) is greater than the first predetermined value (VI). The third predetermined value (V3) is greater than the first predetermined value (VI) and the second predetermined value (V2). The speed threshold values of the vehicle parameter in the control system (200) are configured to be adaptable and can vary based on feasibility requirements. These threshold values are not fixed and depend on factors such as the type of vehicle, its intended use, and the geographical location where the vehicle (100) operates. For example, speed limits, road infrastructure, and common lighting conditions may differ significantly between countries, necessitating specific calibrations. In some vehicles such as but not limited to sports motorcycles, off-road vehicles, and electric vehicles, the first predetermined value (VI) and / or the second predetermined value (V2) may change depending on the type of vehicle (100).However as per one exemplary embodiment such as for a 150cc motorcycle, the first predetermined value (VI) is 40 kilometres per hour, the second predetermined value (V2) is 50 kilometres per hour, and the third predetermined value (V3) is 70 kilometres per hour.

[0049] Further, as per one of the embodiments, the second mode (M2) is the rain mode. When the second mode (M2) is the selected operating mode as per the user input, the control unit (201) selects the second configuration (C2) if the first ambient parameter (Pl) is day time. In one embodiment, the control unit (201) also actuates the pass-by function in addition to the illumination of the headlamp unit (101) in the second configuration (C2).

[0050] Further, the control unit (201) selects the second configuration (C2) during the second mode (M2) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the less illuminance of the ambient light and the vehicle parameter is less than a first predetermined value (VI). This setup provides enough lighting for safe navigation while reducing unnecessary energy consumption in low-speed scenarios.

[0051] The control unit (201) selects the second configuration (C2) during the second mode (M2) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminance of the ambient light and the vehicle parameter is more than a second predetermined value (V2). This prevents over-illumination at higher speeds while still offering sufficient visibility and conserving energy.

[0052] When the second mode (M2) is the selected operating mode, the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the less illuminance of the ambient light and the vehicle parameter is more than a first predetermined value (VI). This ensures maximum brightness and road coverage for improved safety in poorly lit areas, where higher speeds demand better visibility.

[0053] When the second mode (M2) is the selected operating mode, the control unit (201) again selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminanceof the ambient light and the vehicle parameter is less than a second predetermined value (V2). This combination provides enhanced brightness and visibility for slow-moving traffic in highly lit environments, such as urban areas or roads with significant glare from other sources.

[0054] This second mode (M2) dynamically adjusts the functionality of the headlamp unit (101) based on real-time conditions, ensuring optimal visibility and energy efficiency. During the day time, the control system (200) simplifies lighting of the at least one lighting member (101A) by emitting a low beam of light to essential levels for primary road illumination. This setup ensures adequate lighting for rainy conditions while maintaining energy efficiency. While at night time, it tailors brightness and beam configurations of the at least one lighting member (101A) to adjust as per the environmental light levels and the vehicle parameter. By doing so, the second mode (M2) provides riders with the safety and visibility they need for navigating challenging weather conditions without manual intervention.

[0055] In case the selected operating mode is the third mode (M3), the third mode (M3) systematically adapts the settings of the headlamp unit (101) to meet the demands of city driving, where lighting conditions can vary widely. During the third mode (M3), the control unit (201) selects the first configuration (Cl) if the first ambient parameter (Pl) is the day time. In one embodiment, the control unit (201) also actuates the pass-by function in addition to the illumination of the headlamp unit (101) in the first configuration (Cl). This provides sufficient visibility for the vehicle (100) in bright environments without unnecessary power consumption. The first configuration (Cl) ensures that the vehicle (100) remains visible to other road users while maintaining simplicity and energy efficiency.

[0056] When the third mode (M3) is the selected operating mode as per the user input, the control unit (201) selects the second configuration (C2) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the less illuminance of the ambient light, and the vehicle parameter is than a first predetermined value (VI). By emitting the low beam of light from the at leastone lighting member (101A) provides adequate lighting for safe navigation at slower speeds in poorly lit urban areas.

[0057] Further, when the third mode (M3) is the selected operating mode as per the user input, the control unit (201) selects the second configuration (C2) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminance of the ambient light and the vehicle parameter is less than the first predetermined value (VI). This setup ensures appropriate illumination from the at least one lighting member (101A) for slower speeds in well-lit areas such as city streets during night-time.

[0058] When the third mode (M3) is the selected operating mode as per the user input, the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the less illuminance of the ambient light and the vehicle parameter is more than the first predetermined value (VI). This configuration ensures maximum road illumination and visibility at higher speeds, helping the rider respond effectively to any obstacles or road conditions.

[0059] Further, during the third mode (M3), the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminance of the ambient light and the vehicle parameter is more than the first predetermined value (VI). In one embodiment, a pass-by function is activated in addition to the illumination of the headlamp unit (101) in the third configuration (C3), enhancing visibility to other drivers and pedestrians in darker patches or intersections.

[0060] As per one of the embodiments, the fourth mode (M4) is the sports mode. Upon selection of the fourth mode (M4), the control system (200) prioritizes enhanced visibility and performance for high-speed and dynamic riding scenarios. The control system (200) adjusts its lighting configuration based on the time of day, environmental light conditions, and the vehicle parameter to ensure safety and optimal illumination for the rider. The fourth mode (M4) is tailored for performance-oriented riding, offering adaptive lighting that supports high speeds and quick responsiveness to changing conditions.

[0061] When the fourth mode (M4) is the selected operating mode as per the user input, the control unit (201) selects the first configuration (Cl) if the first ambient parameter (Pl) is the day time. In one embodiment, the control unit (201) also actuates the pass-by function in addition to the illumination of the headlamp unit (101) in the first configuration (Cl). This ensures that the vehicle (100) remains visible to other road users while conserving energy. The at least one lighting member (101A) is sufficient for clear day time conditions, providing a streamlined and efficient lighting solution for performance-focused riding.

[0062] When the fourth mode (M4) is the selected operating mode, the control unit (201) selects the second configuration (C2) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the less illuminance of the ambient light, and the vehicle parameter is less than a first predetermined value (VI) and a third predetermined value (V3). This setup provides adequate road illumination for controlled speeds, helping the rider navigate safely in darker conditions.

[0063] When the fourth mode (M4) is the selected operating mode, the control unit (201) selects the second configuration (C2) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminance of the ambient light, and the vehicle parameter is less than the third predetermined value (V3) but more than a second predetermined value (V2). This setup provides sufficient lighting for well-lit environments or areas with ambient lighting from streetlights or oncoming vehicles.

[0064] During the fourth mode (M4), the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the nighttime, the second ambient parameter (P2) is the less illuminance of the ambient light, and the vehicle parameter is more than the third predetermined value (V3). This setup ensures maximum visibility over longer distances. This setup is more suitable for high-speed riding, offering better anticipation of road conditions.

[0065] Further, during the fourth mode (M4), the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the less illuminance of the ambient light, andthe vehicle parameter is more than the first predetermined value (VI) but less than the third predetermined value (V3).

[0066] Further, during the fourth mode (M4), the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminance of the ambient light and the vehicle parameter is less than the third predetermined value (V3) and the second predetermined value (V2).

[0067] During the fourth mode (M4), the control unit (201) selects the third configuration (C3) if the first ambient parameter (Pl) is the night time, the second ambient parameter (P2) is the high illuminance of the ambient light and the vehicle parameter is more than the third predetermined value (V3). In one embodiment, the control unit (201) also actuates the pass-by function in addition to the illumination of the headlamp unit (101) in the third configuration (C3). The integration of the pass-by function enhances communication with other riders, making the fourth mode (M4) a robust and rider-focused lighting solution for fast-paced environments.

[0068] The embodiments shown in Figure 2 are taken together for discussion.Figure 2 illustrates a side perspective view of the vehicle (100) which is a twowheeled motor cycle. However, the present invention is not limited to twowheeled vehicles. The present invention can be worked with three-wheeled vehicles and multi -axled vehicles. The vehicle can be a conventional combustion engine vehicle, an electric vehicle, or a hybrid electric vehicle. The control unit (201) assesses a real time weather information, an obstacle perception data, a road inclination data, a vehicle load data, and a navigational data to optimize the selection of the one of the plurality of configurations (Cl, C2, C3) of the headlamp unit (101). Accordingly, a logic may be incorporated within the control unit (201) to predict road conditions and adjust the at least one lighting member (101A) of the headlamp unit (101) pre-emptively. By analyzing historical data, traffic patterns, and rider behaviour, the control system (200) adaptively configures beam patterns and brightness of at least one lighting member (101A) for upcoming conditions, such as curves, inclines, or high-traffic intersections.This ensures optimal performance without manual intervention. Further, the control system (200) checks the ignition status of the vehicle (100) and if the ignition is off, then the control system (200) does not need to proceed whereas if the ignition is on, then the control system (200) moves to the next step. Thereafter, the control system (200) checks the side stand switch status of the vehicle (100) and if the side stand is engaged, then it does not turn on the headlamp unit (101). Then if the side stand is disengaged, then it turns on only the daytime running lamp (DRL) of the at least one lightning member (101 A).

[0069] As per an embodiment of the present disclosure, when the selected operating mode is the second mode (M2), that is rain mode, and the detected first ambient parameter (Pl) is day time then the control unit (201) only activates the low beam LEDs (LB) and the daytime running lamp (DRL) switches to the front position lamp (FPL). In the scenario where the detected first ambient parameter (Pl) is the night time, the second sensing unit (102B) detects high illuminance of ambient light, and the vehicle parameter is less than the second predetermined value (V2), the second predetermined value (V2) is 50 kilometres per hour (as per one exemplary embodiment such as for a 150cc motorcycle), then the control unit (201) activates the low beam LEDs (LB), the high beam LEDs (HB) and the front position lamp (FPL). In the scenario where the vehicle parameter is greater than the second predetermined value (V2), then the control unit (201) activates the low beam LEDs (LB), and the front position lamp (FPL) from the at least one lightning member (101 A). Thereafter, when the detected first ambient parameter (Pl) is the night time, the detected second ambient parameter (P2) is the less illuminance of the ambient light and the vehicle parameter is greater than the first predetermined value (VI), the first predetermined value (VI) is 40 kilometres per hour (as per one exemplary embodiment such as for a 150cc motorcycle), then the control unit (201) activates the low beam LEDs (LB), the high beam LEDs (HB), and the front position lamp (FPL) from the at least one lightning member (101 A). Otherwise, the low beam LEDs (LB), and the front position lamp (FPL) are activated from the at least one lightning member (101 A) by the control unit (201).

[0070] As per another embodiment of the present disclosure, when the selected operating mode is the third mode (M3), that is urban mode, the detected first ambient parameter (Pl) is day time then the control unit (201) activates only the daytime running lamp (DRL) of the at least one lightning member (101A). Thereafter, when the detected first ambient parameter (Pl) is the night time and the second sensing unit (102B) detects high illuminance of ambient light and the vehicle parameter is less than the first predetermined value (VI), in this case, the control unit (201) activates the low beam LEDs (LB) and the front position lamp (FPL) from of the at least one lightning member (101A). If that is not the condition then, it activates the high beam LEDs (HB), the low beam LEDs (LB), and the front position lamp (FPL) from the at least one lightning member (101 A), in addition to an actuation of the pass-by function. Thereafter, when the detected second ambient parameter (P2) is the less illuminance of the ambient light and the vehicle parameter is less than the first predetermined value (VI), then the control unit (201) activates the low beam LEDs (LB) and the front position lamp (FPL) from the at least one lightning member (101A). Otherwise, when the vehicle parameter is greater than the first predetermined value (VI), then the control unit (201) activates the low beam LEDs (LB), the high beam LEDs (HB) and the front position lamp (FPL) from the at least one lightning member (101 A).

[0071] As per further embodiment of the present disclosure, when the selected operating mode is the fourth mode (M4), that is the sports mode. When the detected first ambient parameter (Pl) is day time then the control unit (201) only activates the daytime running lamp (DRL) from the at least one lightning member (101 A). If the detected first ambient parameter (Pl) is the night time, the detected second ambient parameter (P2) is the less illuminance of the ambient light and the vehicle parameter is less than the third predetermined value (V3), and the third predetermined value (V3) is 70 kilometres per hour (as per one exemplary embodiment such as fora 150cc motorcycle), then the control unit (201) activates the low beam LEDs (LB) and the front position lamp (FPL) from the at least one lightning member (101 A). Thereafter, when the vehicle parameter is greater than the third predetermined value (V3), then the control unit (201) activates the lowbeam LEDs (LB), the high beam LEDs (HB) and the front position lamp (FPL) from the at least one lightning member (101A). Otherwise, when the detected second ambient parameter (P2) is the less illuminance of the ambient light, the vehicle parameter is less than the third predetermined value (V3), then the control unit (201) activates the low beam LEDs (LB), and the front position lamp (FPL) from the at least one lightning member (101 A) in addition to an actuation of the pass-by function. In the scenario where the vehicle parameter is greater than the third predetermined value (V3), then the control unit (201) activates the low beam LEDs (LB), the high beam LEDs (HB) and the front position lamp (FPL) from the at least one lightning member (101A).

[0072] According to another embodiment of the present disclosure, the control system (200) can be integrated with ADAS (Advanced Driver Assistance Systems) features such as collision detection, lane departure warnings, and adaptive cruise control. Accordingly, the headlamp unit (101) can adjust its beam direction dynamically based on inputs from cameras and sensors used for lane tracking. When the control system (200) detects an impending collision or a lane change, it can momentarily increase beam intensity or project directional light to better illuminate the hazard or path.

[0073] According to an embodiment of the present disclosure, in addition to speed and light conditions, the control system (200) can incorporate data from load sensors and inclinometer readings. When the vehicle (100) is on an incline or carrying extra weight, the beam pattern of the at least one lighting member (101A) can be adjusted to prevent the dazzling of oncoming drivers while maintaining optimal road illumination.

[0074] The control unit (201) actuates a pass-by function upon a selection of the one of the plurality of configurations (Cl, C2, C3) of the headlamp unit (101). The pass-by action enhances the safety and communication with other riders and enables the one or more operating modes (Ml, M2, M3, M4) to be a versatile and an effective lighting solution for navigating in fast-paced different environments.

[0075] The control unit (201) actuates a sound-alert system upon a selection of the one of the plurality of configurations (Cl, C2, C3) of the headlamp unit (101).In one of the embodiments, the control system (200) may integrate with the navigation system of the vehicle (100) to further enhance its functionality by syncing with navigation data. Hence, the headlamp unit (101) adjusts its illumination dynamically based on the road ahead. In case, when approaching sharper turns on the road, the headlamp unit (101) projects deeper beams to illuminate the curve and trigger the horn to alert other road users. These adjustments by the control system (200) are tailored to the time of day, location, and traffic conditions, providing a comprehensive safety solution. In conditions where the vehicle (100) is connected to a mobile device, then the control system (200) utilizes the weather data to further enhance its adaptive capabilities. When the speed surpasses the specified threshold, then the control system (200) activates specific beam patterns based on pre-built logic. For instance, in adverse weather conditions like rain or snow, the beam pattern may adjust to increase visibility while minimizing glare for oncoming traffic. This integration of realtime weather information ensures that the control system (200) is always optimized for current driving conditions.

[0076] The embodiments shown in Figure 3 are taken for discussion. Figure 3 illustrates a flow chart of the method (300) for controlling a headlamp unit (101) of a vehicle (100). The method (300) comprises a plurality of steps. A first step (301) of the plurality of steps is detection of a first ambient parameter (Pl) and a second ambient parameter (P2) by a sensor module (102) of the vehicle (100). A second step (302) of the plurality of steps is receiving an input data from the sensor module (102) by a control unit (201) upon the detection of the first ambient parameter (Pl) and the second ambient parameter (P2). A third step (303) of the plurality of steps is determining a selected operating mode of the vehicle (100), by the control unit (201), among a plurality of operating modes (Ml, M2, M3, M4). A fourth step (304) of the plurality of steps is further determining a speed of the vehicle (100) by the control unit (201). A fifth step (305) of the plurality of steps is selecting one of a plurality of configurations (Cl, C2, C3) of the headlamp unit (101) after assessing the first ambient parameter (Pl), the second ambient parameter (P2), the selected operating mode and thespeed of the vehicle (100). A sixth step (306) of the plurality of steps is transmitting an output signal to illuminate the headlamp unit (101) in the one of the plurality of configurations (Cl, C2, C3) being selected. When the rider selects one of the operating modes, the control unit (201) simultaneously adjusts the brightness and beam pattern of the headlamp unit (101). In an exemplary embodiment, at higher speeds, the beam from the headlamp unit (101) adapts to be elongated and focuses to illuminate more of the road ahead. While at lower speeds, it widens in order to improve the visibility of the surrounding area. Similarly, in low illuminance of the ambient light, the headlamp unit (101) brightens and adjusts its angle for optimal road illumination. While in high illuminance of the ambient light, the headlamp unit (101) dims to conserve energy and reduce glare.

[0077] The control system (200) initiates by verifying whether the ignition of the vehicle (100) is on or off. If the ignition is off, then the control system (200) remains inactive as there is no need to operate the headlamp unit (101). Similarly, if the ignition is on, the control system (200) proceeds to the next step, preparing to evaluate other factors that influence the activation of the headlamp unit (101). The control unit (201) checks the status of the side stand switch of the vehicle (100) to ensure rider safety. If the side stand is engaged, then the at least one lighting member (101A) is not illuminated. This prevents unnecessary power usage and ensures the vehicle (100) is stationary. If the side stand is disengaged, then the control system (200) activates the at least one lighting member (101A). According to an embodiment, the control system (200) determines the selected operating mode. If no specific mode is selected by the rider then the control system (200) defaults to the first mode (Ml) which is the manual mode, it allows the rider to adjust headlamp settings manually. The control system (200) collects data from the first sensing unit (102A), the second sensing unit (102B), input of user ride mode, and vehicle speed of the vehicle (100). Based on this data and preset values, it adjusts the settings of the headlamp unit (101) accordingly.

[0078] The disclosure and its embodiments have several advantages. If the selected mode is set to “Auto” in the user interface (104), either via the clustersettings or mobile connectivity then, the control system (200) transitions to automated operation, where it independently controls the pattern of the at least one lighting member (101 A) of the headlamp unit (101) based on the one or more ambient parameters (Pl, P2) and the vehicle parameter. The control system (200) has a built-in fail-safe mechanism which is particularly advantageous because if a malfunction is detected by the control unit (201), then the system automatically redirects to the first mode (Ml). This ensures that the rider retains full control over the settings of the headlamp unit (101) while maintaining safety and functionality even when the automated control system (200) is compromised.

[0079] The control unit (201) enables the emission of the high beam of light by the at least one lighting member (101A) only when it is required, the energy consumption is reduced and the fuel efficiency of the vehicle (100) is enhanced.

[0080] Another advantage of the control system (200) is its ability to dynamically change the beam pattern of the at least one lightning member (101 A) based on driving conditions, thereby enhancing overall safety for the rider. For instance, by reducing the intensity and angle of the beam when facing oncoming traffic, the control system (200) minimizes glare for other drivers, reducing the risk of accidents caused by impaired vision. At the same time, the control system (200) provides consistent and well -distributed illumination of the road, making it easier for riders to spot obstacles, curves, or elevation changes in various environments.

[0081] The control system (200) dynamically adjusts the output from the headlamp unit (101) of the vehicle (100) by considering environmental factors like one or more ambient parameters (Pl, P2), one or more operating modes (Ml, M2, M3, M4), the vehicle parameter and user inputs. This adaptability ensures enhanced visibility and safety under diverse driving conditions, whether it is day time, night time, or challenging weather. The inclusion of customizability and fail-safe mechanisms enables the control system (200) to be versatile, reliable, and suitable for global deployment. In case, when the vehicle parameter exceeds a certain threshold, then the control system (200) functions simultaneously to alert nearby vehicles if poor visibility is detected. If the first ambient parameter(Pl) detects low light levels or the second ambient parameter (P2) identifies poor visibility conditions, then the control system (200) triggers the horn of the vehicle (100). This alert mechanism enhances safety by notifying nearby drivers or pedestrians of the presence of the vehicle (100), especially in low-visibility environments such as fog, heavy rain, or dimly lit roads.

[0082] The present disclosure offers several key advantages such as enhancing both vehicle safety and user experience. By integrating an adaptive control system (200) that adjusts synchronously based on the one or more ambient parameters (Pl, P2), the plurality of configurations (Cl, C2, C3), the one or more operating modes (Ml, M2, M3, M4) and the vehicle parameter ensures optimal visibility and reduces glare for oncoming drivers. This dynamic adjustment eliminates the need for manual intervention for an optimization of the headlamp unit (101). Thereby allowing the riders to focus on the road, and improving safety in varying environments such as poor weather or nighttime driving. The flexibility of the control system (200) in adjusting the settings of the headlamp unit (101) enhances comfort while maintaining energy efficiency. Moreover, the use of the first sensing unit (102A) and the second sensing unit (102B) optimizes the performance of the control system (200), offering accurate detection of ambient light levels. The ability to integrate with mobile devices and navigation systems adds an extra layer of convenience and adaptability. These advantages collectively contribute to automatic adjustments based on time and speed, reduced accident risks, improved rider safety, reduced glare, improved visibility as per varying weather and driving conditions, and reduced battery consumption for a user-friendly control system (200).
