Description

Vehicle and control method thereof RELATED APPLICATIONS The present application claims the benefit of korean patent application No. 10-2024-0160037, filed on 11/12 of 2024, the entire contents of which are incorporated herein by reference. Technical Field The present disclosure relates generally to automotive engineering and, more particularly, to systems and methods for generating and controlling vehicle sound output based on various sensor inputs. The present disclosure utilizes an external speaker, a sensor unit, and a signal processing unit to generate a customized audio signal according to driving conditions of a vehicle and a detected object. Background As the development of electric vehicles continues to progress rapidly, there is an increasing demand for driving sounds other than those of conventional internal combustion engine vehicles. Diesel vehicles naturally produce engine noise while running, but since electric vehicles do not have engine noise, electric vehicles lacking such engine noise are significantly quieter while moving. This reduced noise makes it difficult for pedestrians or other drivers to identify approaching electric vehicles, creating the need for human output of certain sounds to enhance safety. In order to solve this problem, a technology of installing front speakers and rear speakers on the outside of an electric vehicle to generate and output a manual driving sound when the vehicle moves has been developed. The speaker may emit a constant engine or driving sound to inform pedestrians and other vehicles of the movement of the vehicle while the vehicle is traveling. The technology is mainly based on a method of realizing a uniform driving sound by outputting the same sound from a front speaker and a rear speaker of a vehicle. This approach simply focuses on informing that the vehicle is moving by playing the same sounds from front and back simultaneously. However, existing solutions typically focus on simply informing others of the presence of a vehicle through sound output and provide limited ability to adjust or dynamically adapt the sound based on various driving conditions or situations. In addition, sounds output at the same frequency and volume may be used to inform that the vehicle is moving, but the sounds are insufficient in delivering detailed information such as the speed or direction of the vehicle. Thus, there is a need for a more advanced approach that is capable of clearly communicating the driving state of a vehicle through different and high performance sound effects. Disclosure of Invention The present disclosure is directed to providing a vehicle capable of maximizing a high performance sound effect suitable for various driving situations by independently adjusting sound outputs from front and rear speakers of the vehicle, and a method of controlling the vehicle. According to some exemplary embodiments of the present disclosure, there is provided a vehicle including a sound output unit including a first speaker mounted at a front portion of an exterior of the vehicle and a second speaker mounted at a rear portion of the exterior of the vehicle, a sensor unit configured to collect vehicle driving information and object identification information, a first processing unit configured to generate a reference sound using the vehicle driving information and the object identification information, a second processing unit configured to generate each of a first sound to be played from the first speaker and a second sound to be played from the second speaker using the reference sound, and a third processing unit configured to control the first speaker to output the first sound and control the second speaker to output the second sound. The second processing unit may generate the first sound and the second sound according to the vehicle driving information and the object identification information. The second processing unit may generate the first sound and the second sound by modulating the frequency of the reference sound. The second processing unit may modulate the frequency of the reference sound such that the frequencies of the first sound and the second sound are different from each other. The second processing unit may generate the first sound by increasing the frequency of the reference sound and generate the second sound by decreasing the frequency of the reference sound when the vehicle is traveling in a city or a road during the daytime. The second processing unit may generate the first sound and the second sound by reducing the volume of the reference sound when the vehicle is traveling in the residential area at night. When a pedestrian is identified in the traveling direction of the vehicle, the second processing unit may generate a first sound by increasing the frequency and the volume of the reference sound and a second sound by decreasing the frequency and the volume of the reference sound. The second processing unit may generate the first sound and the s
