Description:N AUTOMATIC LIGHTING SYSTEM FOR A VEHICLE AND METHOD THEREOF
TECHNICAL FIELD
[0001]
The present subject matter generally relates to a system and method 5 of an automatic lighting system for a vehicle. More particularly, but not exclusively to for automatically keeping a lighting unit activated for a predetermined period of time in a vehicle and a method thereof.
BACKGROUND 10
[0002]
A conventional vehicle, including saddle type vehicle comes equipped with a headlamp located at the front of the vehicle. The headlamp serves as an illumination source during low-light conditions or at night. The main function of a headlamp is to provide visibility for the user of the saddle type vehicle, ensuring safe navigation on the road and making the vehicle visible 15 to other road users. Generally, the headlamp comprises of a light bulb, which is usually an incandescent, halogen, or more modern LED bulb, which emits the light necessary for illumination. A reflector is positioned behind the bulb, to reflect and direct the light emitted by the bulb forward, focusing it into a beam pattern that lights up the road ahead. The lens covers the front of the 20 headlamp and is usually made of clear, durable material, such as a polycarbonate, to protect the bulb and the reflector while allowing light to pass through without distortion.
[0003]
The primary purpose of the headlamp is to improve the user’s visibility in low-light conditions, such as at dusk, during nighttime, or in 25 adverse weather like fog or rain. It allows the user to see potential hazards on the road, such as obstacles, pedestrians, or other vehicles. Besides helping the user see, the headlamp also serves as a safety feature by making the vehicle more visible to other drivers and pedestrians. This is especially crucial during low-visibility conditions when other road users may have difficulty spotting 30 the smaller profile of a vehicle.

[0004]
However, in conventional vehicles, when a user has parked their vehicle in a dark area or at night, having the headlamps turn off immediately after the vehicle is turned off can result in reduced visibility when exiting the vehicle and navigating the surroundings. In some situations, such as in poorly lit areas or in inclement weather, it may be dangerous to have the headlamps 5 switched off immediately after turning off the vehicle thereby provide no visibility to other road users or pedestrians. Since there is sudden darkness due to the headlamps is turned OFF after the vehicle is turned OFF, the surrounding is not illuminated thereby offering an unsafe environment.
[0005]
Conventional vehicular lighting systems predominantly rely on 10 headlamp assemblies for visibility during parking. However, during reverse parking scenarios, the efficacy of headlamps is diminished as the primary focus is on the vehicle's rearward trajectory. Therefore, there is a need to strategically employ various lighting units in the vehicle to enhance visibility in proximity to the vehicle during parking, thereby providing an improved 15 and more contextually relevant lighting solution.
[0006]
In addition to this, it is also necessary to ensure that the headlamps are not turned ON for a long period of time since an extended use of the headlamps can lead to draining the battery. Moreover, users may occasionally forget to turn off their headlamps manually after parking, leading to drained 20 batteries and inconveniencing the user at a later stage. The headlamps are turned ON even when the vehicle is not in use, or when nobody is near the vehicle and needs their surroundings to be illuminated.
[0007]
Therefore, it is necessary to for a user to be able to configure the settings of the headlamps as per their requirements. It is also necessary that a 25 balance is sought between ensuring safety and convenience for drivers while minimizing potential battery drain and disturbance to others.
[0008]
Additionally, a safety feature should come at the convenience of the user, and should be affordable with fewer additional parts. Conventional lighting systems, including headlamp systems, with additional features 30 involve supplementary parts which have maintenance requirements, and the malfunctioning of such supplementary parts may increase the cost of repairs

and servicing
. Moreover, finding replacements might be even more challenging, which may come at a premium cost compared to standard parts. Furthermore, complexity to the functionality can lead to potential reliability issues, which may require more frequent maintenance or repairs.
[0009]
Thus, there is a need in the art for a method and a system for an 5 automatic lighting system for a vehicle, and a method thereof which addresses at least the aforementioned problems and other problems of known art.
[00010]
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, 10 as set forth in the remainder of the present application and with reference to the drawings.

[00051]
Figure 3 exemplarily illustrates a flowchart depicting the method of operation of the automatic lighting system for a vehicle in accordance with an embodiment of the present disclosure.
[00052] The method initiates the process at step 301. The control unit (208) 20 receives a plurality of vehicle parameters. The control unit (208) based on the vehicle parameters, determines when a plurality of predefined conditions are satisfied at step 303. The plurality of predefined conditions comprise of if the level of ambient light surrounding the vehicle (200) is below a threshold level, AND if the vehicle speed zero, AND if the stand status enabled. The control 25 unit (208) sends the determination of the plurality of predefined conditions is satisfied to a lighting unit controller (210a). Therefore, the control unit (208) checks the conditions for which the automatic lighting system (100) should switch to an ON state. Upon checking this condition, the control unit (208) then sends the lighting unit controller (210a) for further execution of the 30 automatic lighting system (100) at step 304. The plurality of predefined

15
conditions ensure that the vehicle is coming to a stop, and the user is about to
deboard the vehicle.
[00053]
At step 305, the lighting unit controller (210a) receives the predetermined time period from the control unit (208). At step 306, the lighting unit controller (210a) receives the status of the first function from the 5 control unit (208). At step 307, the lighting unit controller (210a) receives the status of the first function from the control unit (208).
[00054]
At step 308, the lighting unit controller (210a) checks if the status of the first function enabled. If yes, then the method moves to step 309. If the status of the first function is not enabled, i.e., the user has not turned ON the 10 automatic lighting system functionality, the method moves to step 302, where the vehicle parameters are gauged again, to determine whether the plurality of predefined conditions are fulfilled.
[00055]
At step 309, the lighting unit controller (210a) checks if the ignition key input transitions from ON to OFF. This indicates that the user is ready to 15 park the vehicle, therefore, the automatic lighting system (100) should start working. If the ignition key input does not transition from ON to OFF, i.e., the user is not about to leave the vehicle, therefore the automatic lighting system functionality is not needed, the method moves to step 302, where the vehicle parameters are gauged again, to determine whether the plurality of 20 predefined conditions are fulfilled.
[00056]
At step 310, the control unit (308) and the lighting unit controller (210) have determined that the vehicle is coming to a stop and is going to be parked. Therefore, the lighting unit controller (210a) switches the illumination state of the lighting unit (210) to ON for a predetermined time 25 period as entered by the user. The method terminates at step 311.
[00057]
Let's consider a working example of the described automatic lighting system with specific values for illustration. The control unit (208) is integrated into the vehicle’s (the vehicle according to an embodiment being a motorcycle), speedometer. The lighting unit (210) has a lighting unit 30
