PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD OF THE INVENTION
Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to an acoustic vehicle alert system and related method thereof.
BACKGROUND OF THE INVENTION
With the rising demand for alternative modes of transportation that are environmentally friendly and to improve performance, increase fuel economy and reduce emissions from conventional internal combustion engines, electric drive vehicles, such as hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and all-electric vehicles (EVs), hybrid electric vehicles have been developed.
Typically, the electric drive vehicles produces much less noise than conventional internal combustion engines vehicles and hence are often too quiet to be heard, especially at low speeds. As a result, pedestrians particularly, older adults, children, blind people walking on a roadway are unable to detect an approaching vehicle and are at high risk of vehicle-pedestrian collisions and accident.
In an effort to substantially reduce the number of accidents caused by non-detection of approaching vehicles by the pedestrian, various government regulations have been brought into force which mandates that all non-IC engine vehicles should include acoustic vehicle alert system that should generate certain decibel of sound signal in the form of the audio alert while vehicle is moving in forward direction or reverse direction and with a vehicle speed up to 20KM/H. Thus, various types of pedestrian alert systems are developed by vehicle manufacturers to alert the vehicles of the surrounding vehicles and pedestrian of potential accidents, collision.
An exisiting vehicle pedestrian alert system installed on the vehicle is configured to automatically generate audio alert signals in a predefined interval of times,

without determining the presence of pedestrian, a pedestrian-like objects in a vehicle pathway. This may sometime result in undesirable noise creation. Furthermore, the audio alert signals transmitted by speakers installed on the vehicle are particularly at a predetermined constant decibel value and hence may remain unheard by pedestrian, particularly older adults, blind people or animal in the vehicle pathway. Thus, the current acoustic vehicle alert system is an ineffective in providing an accurate alert signals to substantially reduce the potential vehicle-pedestrians collisions.
Present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the known arts.

The generation of the audio messages may be equal and greater than a predetermined decibel value or below the predetermined decibel value and based on a plurality of determining factors by the AVAS control module (112). That is, in an example, during determination of the vehicle surrounding condition as daytime condition and detection of at least one pedestrian, the generated audio message decibel may be generated with a decibel equal to or greater than the predetermined decibel value. In another example, during

determination of the vehicle surrounding condition as nighttime condition, the generated audio message decibel may be below the predetermined decibel value.
Moreover, in an embodiment of the present disclosure, the disclosed acoustic vehicle alert system (AVAS) (100) is configured to determine an accurate location of pedestrians, pedestrian like object, objects in real-time, and orients the at least one of the front and rear speakers (119), (121) to the predetermined angle before the acoustic alert signal is transmitted such that the audio alert message of the approaching vehicle can be recognized and heard precisely, thereby significantly reducing accidents, vehicle collision, Advantageously, the orientation of the at least one of the front and rear speakers (119), (121), upon actuation, is configured to alert pedestrians which may include adults, blind-persons, children, dogs, cats, livestock, or other animals. Thereby, facilitating an accurate alert signal transmission and an enhanced acoustic awareness from the vehicle to a surrounding of the vehicle and pedestrian located at the predetermined distance in the real-time. Additionally, an illustrated embodiment discloses an improved acoustic vehicle alert system (AVAS) (100) configured to modulate the decibel values of the generated acoustic sound signal based on the determined ambient condition. Also, the improved acoustic vehicle alert system (AVAS) (100) is configured to determine a predetermined direction for orienting the at least one of front and rear speakers (119), (121) to directing the transmission of the audio alert corresponding. This facilitates in reducing the sound pollution in case there are no pedestrians that need alert and at the same time directing the sound speaker towards the pedestrian, thereby providing an effective alert system of approaching vehicles in pedestrian pathway.
Figure. 2 shows a flow-chart illustrating a method of operating the acoustic vehicle alert system (AVAS) (100) for the vehicle, in accordance with an embodiment of the present disclosure. In an illustrated embodiment, the acoustic vehicle alert system (AVAS) (100) includes the front radar (101) and the front camera module (102), configured to generate the first predetermined data, the rear radars (103), (104) and the rear camera module (105), configured to generate the second

predetermined data, the user interfaces such as the user select module (107), the microphone (106), and the ambient sensor (108), configured to generate the third predetermined data. The ADAS front controller (109) performs processing of the first predetermined data to generate a front vehicle data map with a predefined information of the front region of the vehicle. The ADAS rear controller (110) performs processing of the second predetermined data to generate a rear vehicle data map with a predefined information of the rear region of the vehicle.
And, the infotainment control unit (111) performs processing of the third
predetermined data to generate a cumulative data corresponding to the ambient
sensor and the user interfaces. The AVAS control module (102) being
communicatively coupled to the ADAS front controller (109), the ADAS rear controller (110) and the infotainment control unit (111) is configured to determine and generates the predetermined acoustic alert sound signal to be transmitted to the pedestrian via that at least one of the front and rear speakers (119), (121). Particularly, the AI module (114) coupled to the AVAS unit and integrally built deep learning algorithm and predictive logic creates an actuation signal for the at least one of the front and rear speakers (119), (121). On generation of the actuation signal, the at least one of the front and rear speaker is oriented at the predetermined angle corresponding to the location of the pedestrian from the predetermined distance of the vehicle. Upon orienting, the at least one of the front and rear speakers (119), (121) generates the real-time acoustic alert signal to alert the pedestrian of the approaching vehicle.
With reference to an illustration, the method starts at step 201 when ignition of the vehicle is in the ON condition. In an illustrated embodiment, at step 202, the first, second and third predetermined data is determined by the ADAS front and rear controllers (109), (110) and the infotainment control unit on the vehicle. At step 203, a vehicle control unit determines if the acoustic vehicle alert system is disabled. In an illustrated embodiment, the acoustic vehicle alert system is configured to be automatically activated upon vehicle Ignition ON. In situation, wherein the acoustic vehicle alert system (AVAS) (100) is disabled based on user

preferences through the actuation of an override switch, the vehicle control unit is configured to determine the actuation/deactivation condition of the acoustic vehicle alert system (AVAS) (100) as illustrated at step 203. If the acoustic alert system is in activated condition, then the AVAS control module determines the vehicle speed based on the vehicle speed signal received from the vehicle speed sensor, at step 204. At step 205, if the AVAS control module (102) determines that the vehicle speed is lesser than a predetermined vehicle speed, then the method moves to step 206, else the method moves to step 204. At step 206, the AVAS control module (102) determines and processes the data from at least a portion of the third predetermined data. That is, the AVAS control module (102) determines the ambient condition of the vehicle. At step 208, if it is determined that an ambient condition signal is indicative of the daytime condition, then further at step 209 the AVAS control module (102) determines the presence of at least one pedestrian located at the predetermined distance from the vehicle and transmits a predetermined orientation signal to the at least one of front and rear speakers (119), (121) of the vehicle. At step 210, the at least one of front and rear speakers (119), (121) is oriented at a predetermined angle such that it faces the location of the pedestrian. Further, upon orientation, the at least one of front and rear speakers (119), (121) is actuated by the electric motors (113), (120) to generate in real-time the audio alert messages in the form of the acoustic sound signal to alert the pedestrian in the vicinity of the approaching vehicle, at step 211. The acoustic sound signal generated, as illustrated in step 211 is equal to or greater than a predetermined decibel value. However, if at step 206 if it is determined that an ambient condition signal is indicative of the nighttime condition, then an audio alert messages in the form of the acoustic sound signal is generated in a decibel value below the predetermined value to alert the pedestrian in the vicinity of the approaching vehicle, at step 207.
