Description:TECHNICAL FIELD
[001] The present disclosure relates to the field of saddle type vehicles, for example, two-wheeled vehicles. Particularly, the present disclosure relates to a front light unit and the associated light unit sensor of the two-wheeled vehicle.

BACKGROUND
[002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.
[003] Generally, in saddle-ride type vehicles, for example, motorcycles, three-wheeled motor vehicles, ATVs (all terrain vehicles), etc., when the vehicle corners or turns at an intersection, a rider operates a handlebar and additionally shifts his/ her own weight in order to counteract centrifugal force acting on a vehicle body. As a result, the vehicle turns with a banking angle leaning to an inner side of a curve. Typically, the vehicle is provided with a plurality of front lights, for example, a headlight and sub-lights (commonly, called as additional lights) to ensure illumination of the field ahead of the vehicle. When the vehicle is running on a straight road, an illumination range of the headlight spreads evenly to the left and right in an area ahead of the vehicle. When the vehicle takes a turn, for example a left turn, the vehicle runs with the vehicle body inclined to the left. Accordingly, the illumination range of the headlight spreads downward to the left and an illumination range in an area inside the curve and ahead in the advancing direction is reduced. To balance said reduction in the illumination range, the sub-lights are provided along with the headlight that adjust illumination (ahead of the vehicle) based on the banking angle of the vehicle during the turn. Also, the sub-lights are automatically turned ON/OFF depending upon the banking of the vehicle. For instance, upon taking the left turn, the left sub-light automatically turns ON. Similarly, upon taking the right turn, the right sub-light automatically turns ON.
[004] In known vehicles, banking angle measurement sensors are employed to measure the banking angle of the vehicle. Said sensors are positioned adjacent to the sub-lights, and thus are provided in the front region (i.e., the steering assembly) of the vehicle. Said positioning of the measurement sensor makes the light unit bulky and complex. Also, the measurement sensor is required to be mounted horizontally and requires cooling, and thus, when positioned within the light unit, poses the challenge for packaging of the measurement sensor and the light unit.
[005] Additionally, due to operational parameters and other accuracy/ calibration needs, it is required to mount the measurement sensor at or near to the mid plane or centre of vehicle. Further, in conventional vehicles, the measurement sensor is mounted behind other components, and it is required to disassemble said other components for removing the measurement sensor either for servicing or calibration purposes.
[006] Accordingly, there remains a need in the domain to provide a vehicle that addresses at least the problems identified above.

SUMMARY
[007] The one or more shortcomings of the prior art are overcome by the system/assembly as claimed, and additional advantages are provided through the provision of the system/assembly/method as claimed in the present disclosure. Additional features and advantages are realized through the techniques of the present disclosure. Other embodiments and aspects of the disclosure are described in detail herein and are considered a part of the claimed disclosure.
[008] Pursuant to an aspect of the present disclosure, in an embodiment, a vehicle is disclosed. The vehicle comprises a body frame that comprises a head tube, and a main tube extending downwardly and rearwardly from the head tube. The main tube has a front tube portion, and a step-through tube portion extending horizontally from the front tube portion. The vehicle further comprises a steering assembly pivotably coupled to the head tube, and a light unit mounted on a front portion of the vehicle.

[019] In another non-limiting embodiment of the present disclosure, the light unit sensor mounted within a floorboard of the vehicle.
[020] Within the scope of the present disclosure, mounting the light unit sensor on the step-through tube portion of the vehicle allows the light unit sensor to accurately determine the angle of inclination of the vehicle and thus control or adjust (raise or lower) the level of the light unit precisely. Also, for the reason that the light unit sensor is mounted horizontally on the vehicle, and thus calibration of the light unit sensor is easy and it is easy to remove the light unit sensor for service purposes.
[021] Further, the floorboard of the vehicle facilitates a larger mounting space compared to the steering assembly, and thus it is easy to horizontally mount the light unit sensor and provide cooling equipment for the light unit sensor making the packaging of the light unit sensor on the vehicle convenient.
[022] Additionally, mounting brackets and cushion of the light unit sensor prevent transferring vibrations of the vehicle to the light unit sensor.

Further, in the embodiment where the light unit (130) comprises the sub-lights (130B), the electronic control unit (170) may be adapted to adjust a level of the sub-lights (130B) based on the angle of inclination determined by the light unit sensor (140). The electronic control unit (170) may be adapted to raise or lower the level of the sub-lights (130B) based on the angle of inclination determined by the light unit sensor (140).
[065] In a working implementation, based on the angle of inclination determined by the light unit sensor (140), the light unit sensor (140) sends signals to the electronic control unit (170) corresponding to the determined angle of inclination. The electronic control unit (170) fetches and executes the computer-readable instructions stored in the memory and processes the signals received from the light unit sensor (140) and determines an adjustment level required in the level of the light unit (130), and corresponding to the said determined adjustment level, the electronic control unit (170) sends signals to an actuating unit of the light unit (130) for adjusting, for example, raising or lowering, the level of the light unit (130) to illumination the region ahead of the vehicle (100).
[066] Within the scope of the present disclosure, mounting the light unit sensor (140) on the step-through tube portion (114B) of the vehicle (100) allows the light unit sensor (140) to accurately determine the angle of inclination of the vehicle (100) and thus adjust (raise or lower) the level of the light unit (130) precisely. Also, for the reason that the light unit sensor (140) is mounted horizontally on the vehicle (100), and thus calibration of the light unit sensor (140) is easy.
[067] Further, the floorboard (104) of the vehicle (100) facilitates a larger mounting space compared to the steering assembly, and thus it is easy to horizontally mount the light unit sensor (140) and provide cooling equipment for the light unit sensor (140) making the packaging of the light unit sensor (140) on the vehicle (100) convenient.
[068] Additionally, mounting brackets (150) and cushion (160) of the light unit sensor (140) prevent transferring vibrations of the vehicle (100) to the light unit sensor (140).
