Description:HEAD LAMP CONTROL FOR A VEHICLE
TECHNICAL FIELD
[0001] The present subject matter generally relates to a method for a headlamp control. More particularly, but not exclusively to a method of 5 controlling the beam from a headlamp of the vehicles.
BACKGROUND
[0002] The field of automotive engineering has seen significant advancements in recent years, particularly in safety systems and lighting technology. Headlamp control systems play a crucial role in ensuring optimal 10 visibility for drivers while also minimizing glare for other road users. However, several technical challenges have emerged in traditional headlamp control mechanisms, prompting the need for innovative solutions such as the claimed present disclosure.
[0003] Traditional systems rely on manual input from the driver to adjust 15 the beam intensity and switch between low and high beams. They require the driver's judgment, which can be subjective and prone to error. Constant attention and adjustment are needed, which can be distracting and inconvenient for the driver, especially in varying road and traffic conditions. Consequently, manual systems may lead to instances of improper beam 20 adjustment, causing glare for other road users or insufficient visibility for the driver.
[0004] Traditional vehicles typically employ manual switches to control the headlamps. These switches require the driver's active engagement, featuring positions for off, low beam, and high beam. While this method is 25 straightforward, it lacks automation and may lead to instances where the headlamps are inadvertently left on or off. Moreover, users must manually switch between different beam modes, which can be cumbersome and distracting, particularly while driving. This limitation reduces user convenience and may result in suboptimal usage of the vehicle's lighting 30 system.
3
[0005] In contrast, some vehicles utilize automatic headlamp control systems, equipped with sensors that detect ambient light levels and activate the headlamps accordingly. Additionally, these systems may include features where the headlamps remain illuminated for a short duration after turning off the ignition. While automatic systems offer convenience by eliminating the 5 need for manual intervention, they may lack user control and customization options. Users have limited flexibility to activate the headlamps according to their specific preferences or immediate requirements, as these systems typically operate based on predefined settings.
[0006] Another conventional approach involves ignition-controlled 10 headlamps, where the headlamps remain on for a specified duration after turning off the ignition. This functionality is usually controlled by the vehicle's electrical system. However, similar to automatic systems, ignition-controlled headlamps suffer from fixed timing constraints. The duration for which the headlamps remain on is typically predetermined and may not cater 15 to varying user needs or preferences. Consequently, users have limited control over when the headlamps should be turned on or off, leading to potential inconvenience and suboptimal usage scenarios.
[0007] Furthermore, some conventional vehicles implement battery-saving mechanisms to prevent excessive drain on the battery. These mechanisms 20 automatically switch off the headlamps after a certain period, regardless of user input or driving conditions. While this approach conserves battery power, it may compromise safety in certain situations. Automatic shut-off mechanisms could inadvertently leave the vehicle without adequate lighting, particularly in low-light conditions or during brief stops. This limitation 25 highlights the need for a more flexible and user-centric approach to controlling vehicle headlamps, addressing the shortcomings of existing methods.
[0008] Thus, there is a need in the art for a method and a system for a headlamp control for a vehicle which addresses at least the aforementioned 30 problems and other problems of known art.
4
[0009] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings. 5

The embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. However, the present disclosure is not limited to the present embodiments. The present subject matter is further described with reference to accompanying figures. It should 10 be noted that the description and figures merely illustrate principles of the present subject matter. Various arrangements may be devised that, although not explicitly described or shown herein, encompass the principles of the present subject matter. Moreover, all statements herein reciting principles, aspects, and examples of the present subject matter, as well as specific 15 examples thereof, are intended to encompass equivalents thereof.
[00041] Figure 1 exemplarily illustrates an environment diagram in accordance with an embodiment of the present disclosure. The vehicle (100) comprise of a control unit (102) and an illumination unit (104). A signal transmitter (106) is in communication with the control unit (102). The vehicle 20 (100). The control unit (102) acts as a central processing unit within the vehicle (100), responsible for coordinating the operation illumination unit (104)based on signals received from the signal transmitter (106). In anembodiment the signal transmitter (106) may include but not limited to a keyfob, a user digital device, a standalone remote, a voice-activated systems, a 25 gesture interfaces, a biometric device, a wearables device, a home automation system, and an embedded telematics system. The control unit (102) comprises of a microcontroller programmed with predefined algorithms and criteria for controlling the illumination unit (104).
[00042] In an embodiment the signal transmitter (106) comprises of buttons 30 configured to turn the headlamp on or off, switch between beam modes, and
9
adjust an intensity of the illumination unit (104). Each of the button press may be configured to generate a unique signal pulse that is transmitted to the control unit (102) of the vehicle (100) from the signal transmitter (106). [00043] In an embodiment the illumination unit (104) comprises of at least one light source, at least one reflector, at least one lens, and an input output 5 unit. In an embodiment the illumination unit (104) is configured to emit light in both low beam and high beam modes, with adjustable intensity levels.
[00044] The control unit (102) communicates with both the signal transmitter (106)and the illumination unit (104) to initiate actions which may includeturning the headlamp on or off, switching between low beam and high beam 10 modes, and adjusting the intensity of the headlamp.
[00045] Figure 2 exemplarily illustrates a flowchart in accordance with an embodiment of the present disclosure. The method initiates the process at step 200 and proceeds to step 202 where a control unit (102) detects a signal pulse from a signal transmitter (106). In an embodiment the Signal pulses are 15 discrete bursts of electrical or electromagnetic energy conveying information from a signal transmitter (106) to a control unit (102). These pulses may represent a binary data, where each pulse corresponds to a specific bit, or an analog information such as varying voltage levels or frequencies. These pulses may encode control commands or instructions for the control unit 20 (102)to execute specific actions or operations. The detection of these signalpulses by the control unit (102) initiates a process whereby the transmittedinformation is interpreted and acted upon, facilitating communication andcoordination within the system. The step proceeds to 204 where the controlunit determines whether the signal pulses from a signal transmitter (106) 25 corresponds to a first predefined value. In an embodiment the first predefined value corresponds to a single pulse from the signal transmitter. The recognition of the signal pulse by the control unit (102) corresponding to the first pre-defined value progresses the step to 206 where a battery voltage is checked. If the battery voltage is greater than a predefined voltage, then the 30 step proceeds to 208 otherwise the step goes back to step 204. At 208 the
10
control unit (102) calculates and compares a distance between the vehicle (100)and the signal transmitter (106) with a predefined distance. In anembodiment the predefined distance corresponds to 100 meters between thevehicle (100) and the signal transmitter (106). The process then proceeds tostep 208a. 5 [00046]
Figure 3 exemplarily illustrates a flowchart in accordance with an embodiment of the present disclosure. The flowchart as described in figure 3 initiates at step 208a and proceeds to step 210 where the distance of the signal transmitter (106) and the vehicle (100) is compared against a predefined value. At step 210 if the distance of the signal transmitter (106) and the 10 vehicle (100) is greater than the predefined value then the step 210 proceeds to step 212 where the control unit (102) detects whether the number of signal pulses from the signal transmitter (106) corresponds to either a second predefined value or a first pulse duration. The first pulse duration may correspond to a prolonged signal transmission for a time duration. In an 15 embodiment the first pulse duration is at least for 3 seconds. In an embodiment the second predefined value for the number of signal pulses is configured to vary intensity of the illumination unit (104). In an embodiment the second predefined value for the number of signal pulses may corresponds to a consecutive signal pulse within a time frame. In an embodiment the 20 second predefined value for the number of signal pulses may be 3 signal pulses within 1 second. At step 212 if the control unit (102) detects first pulse duration, then the step proceeds to 214 where a signal is transmitted to the illumination unit (104) to enable a full-intensity beam. At step 212 if the control unit (102) detects second predefined value, then the step proceeds to 25 step 216 where a signal is transmitted to the illumination unit (104) to vary intensity of the illumination unit (104). The step then proceeds to 218 were the control unit (102) checks whether a predetermined time has lapsed. If the predetermined time has lapsed, then the step proceeds to 220 where the illumination unit is turned OFF. At step 210 if the distance of the signal 30 transmitter (106) and the vehicle (100) is less than the predefined value then the step 210 proceeds to step 212a where the control unit (102) detects
11
whether the number of signal pulses corresponds to either a third predefined value or a second pulse duration. The second pulse duration may correspond to a prolonged signal transmission for a time duration. In an embodiment the second pulse duration is at least for 3 seconds. At step 212a if the control unit (102) determines the third predefined value for the number of signal pulses 5 then the step proceeds to 214a where the illumination unit (104) is configured to switch between high beam and low beam of the illumination unit (104) intensity. At step 212a if the control unit (102) determines the second pulse duration then the step proceeds to 216a configured to vary the intensity of the illumination unit (104). In an embodiment the third predefined value for the 10 number of signal pulses may corresponds to a consecutive signal pulse within a time frame. In an embodiment the third predefined value for the number of signal pulses may be 3 signal pulses within 1 second. The step then proceeds to 218 were the control unit (102) checks whether the predetermined time has lapsed. If the predetermined time has lapsed, then the step proceeds to 220 15 where the illumination unit is turned OFF. The process ends at step 222. [00047] A detailed working example of the present disclosure can be explained through a scenario. Assume that John a vehicle rider activates the Follow Me Lamp feature using his Signal transmitter, triggering the control unit to start its operations. The control unit promptly detects the signal pulse
20 emitted by the Signal transmitter and proceeds to check the battery voltage to ensure it's sufficient for operation.
[00048] Once the initial checks are complete, the control unit initiates the distance calculation between the vehicle and the signal transmitter. Upon finding the distance to be within close range, specifically less than 100 meters, 25 the control unit proceeds to activate the low beam of the headlamp at full intensity. This ensures adequate illumination.
[00049] In a different scenario John decides to adjust the headlamp settings. If the distance between the vehicle and the signal transmitter exceeds 100 meters, the control unit actively monitors for signal pulses from the Signal 30 transmitter. If a prolonged signal transmission lasting 3 seconds is detected,
12
the control unit enables the full-intensity beam for enhanced visibility. Alternatively, if the control unit detects 3 consecutive pulses within 1 second, it adjusts the intensity of the headlamp, accordingly, ensuring optimal lighting based on the surrounding conditions. [00050] In an alternate scenario, if the distance between the vehicle and the
5 signal transmitter remains less than 100 meters, the control unit continues to monitor for signal pulses. In this scenario, if 3 consecutive pulses within 1 second are detected, the control unit dynamically switches between high beam and low beam of the headlamp intensity. If a prolonged signal transmission of 3 seconds is detected, the control unit adjusts the intensity of 10 the headlamp to maintain optimal lighting conditions. After 3 seconds of inactivity, the control unit automatically turns off the illumination unit, thereby preventing unnecessary power consumption.
[00051] This comprehensive approach allows John to customize the headlamp settings according to his preferences and the surrounding 15 environment, ensuring safety and flexibility for the user.
