Description

This application claims the benefit of Korean Patent Application No. 10-2024-0057915, filed on Apr. 30, 2024, which is hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE DISCLOSURE Field of the Disclosure Embodiments of the present disclosure are applicable to vehicles of all fields, and more particularly to a lamp control system for controlling light distribution formed in a front area including a driving lane, a lamp control method for the same, and a vehicle including the same. Discussion of the Related Art As the use of light emitting diode (LED) light sources in vehicle lamps continues to increase, various high beam and low beam vehicle lamp modules are on the rise. In particular, the trend of integrating high-low beam vehicle modules is becoming prominent. Such modules are well-received in the market due to the low cost, compact size, simple structure, and comprehensive functionality. As the interest in safety during vehicle driving increases, a significant number of driving accidents occur each year due to the improper use of high beams. Vehicle lamp modules with adaptive driving beam (ADB) functionality may somewhat resolve contradictions in the use of high-low beams. Specifically, the vehicle lamp modules with ADB functionality may provide excellent visibility to vehicles and thus preventing glare for other drivers. The ADB function includes a smart control capability. That is, the ADB function may independently control each LED, thereby allowing for real-time control of the lighting area and brightness and effectively preventing glare for other vehicles and pedestrians. Conventional vehicles with ADB functionality have been used in a way where the driver directly specifies a speed at which the ADB function is activated and the ADB function automatically activates when the vehicle is driving above the corresponding speed. However, the conventional method controls the lighting without considering the environment of a road where the vehicle is driving. This results in issues where the lighting becomes dimmer on relatively dark roads or brighter in relatively bright areas, hindering the visibility of pedestrians and other drivers. In addition, the ADB function may activate earlier than the driver desires, leading to numerous malfunctions due to camera recognition errors, or the ADB function may activate later than the driver desires, causing frustration for the driver. In order to secure the visual field of a driver who rides in a vehicle, there exists technology related to a dynamic lane carpet, etc. that irradiates a carpet-shaped beam in front of the vehicle in a driving situation, but there is a problem that this technology is far from efficient in cost and function. SUMMARY OF THE DISCLOSURE Accordingly, the present disclosure is directed to a lamp control system, a lamp control method, and a vehicle that substantially obviate one or more problems due to limitations and disadvantages of the related art. An object of the present disclosure is to provide a method for efficiently controlling light distribution according to the driver's driving tendency. Another object of the present disclosure is to provide a method for transmitting the driver's intention of a subject vehicle to a following vehicle (i.e., a rear vehicle) by controlling distribution of light irradiated to a destination lane when changing lanes. Technical subjects to be solved by the present disclosure are not limited to the above-mentioned technical solutions, and it should be noted that other technical subjects not described above can be understood by those skilled in the art from the description of the present disclosure below. In accordance with an embodiment of the present disclosure, a lamp control system may include: a lamp configured to form a light distribution (LV) in a front area including a driving lane; a sensing module configured to detect a change in the driving lane of a vehicle; and a processor configured to control the lamp so that a brightness distribution, a formation position, or a shape of the front area where the light distribution (LV) is formed is variable based on information about a driving lane change and information about a driver's driving tendency. The processor may be configured to, upon receiving the driving lane change information, control the front area to include a target lane corresponding to a destination lane from among adjacent lanes of the driving lane. The processor may control brightness of an area where the LV is formed in the target lane from among the front area to be greater than brightness of an area where the LV is formed in the driving lane from among the front area. The processor may control brightness distribution of an area where the LV is formed in the target lane from among the front area based on driver's lane change tendency information among the driver's driving tendency information. The driver's lane change tendency information may be set based on
