DESC:TECHNICAL FIELD
[0001] The present disclosure relates to the field of wireless voice communication, and in particular, relates to an in-vehicle voice communication system and a method thereof.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art.
[0003] Drive-through for food, beverages, and other necessities is a popular take-out service that is employed by many businesses to allow customers to purchase and collect products without having to exit their vehicles. In such set-ups, orders are placed using a microphone or a receptionist at one window and picked from another window in person. In the existing systems of drive-through ordering and pickup, the person ordering the product needs to either step out from the vehicle to pick up the order and/or roll down the window to speak to the receptionist and/or to collect the order. Also, in many cases, the audio quality of voice-based communications between people in the vehicle and the receptionist/operator is weak due to varying conditions. This is a tedious and time-consuming process and also impacts the number of customers serviced in a day, and hence, the revenue generation.
[0004] The arrangements and logistics associated with drive-throughs are optimized to minimize the time of service, as the same is inversely correlated with revenue. In most cases, customers/users generally spend about 256 seconds entering, placing orders, and collecting the products via the drive-throughs. Of the 256 seconds, a considerable portion of time is spent in establishing means of communication with a drive-through operator who takes the order from the customer. Usually, drivers open the window or the door of the vehicle to communicate with the operators. However, opening doors or windows often contribute to a significant proportion of the time. Furthermore, the driver may be unwilling to expose themselves to the external environment, such as when the temperature is >35 Celsius or < 0 Celsius, during rain or snow, etc. Additionally, noise and distance between the driver and the operator may also adversely affect the quality of communication. Other solutions include establishing wireless communication with the operators through the communication systems embedded in the vehicle. However, establishing communication channels using existing in-vehicle communication systems may not necessarily be reliable and may suffer from latency issues.
[0005] The ground infrastructure surrounding roads provides abundant visual information for both drivers and passengers while the vehicle is in motion. However, due to the vehicle's movement, occupants may struggle to capture or record pertinent information from roadside sources, leading to potential data loss. Conversely, publishers of roadside information lack effective channels to deliver content to interested vehicle occupants.
[0006] Therefore, there is a need to overcome the above-mentioned technical problems, limitations, and shortcomings associated with existing solutions, by providing an improved, efficient, and cost-effective in-vehicle voice communication system and a method thereof.

SUMMARY
[0018] The present disclosure relates to the field of wireless voice communication, and in particular, relates to an in-vehicle voice communication system and a method thereof.
[0019] The present disclosure relates to wireless voice communication, and in particular, relates to an in-vehicle voice communication system and method thereof to facilitate seamless interaction between vehicle occupants and external service locations. The system includes first communicator units positioned at predefined locations, each equipped with a broadcasting beacon module to transmit credential signals within a predefined range. Additionally, the system includes a second communicator unit installed within a vehicle with a beacon listener module. This beacon listener module detects the broadcasted credential signals from the first communicator units when the vehicle enters its range, triggering the establishment of a secure communication channel.
[0020] Additionally, the first communicator units and second communicator unit are equipped with input and output devices for audio data capture, transmission, reception, and playback. These first communicator units and the second communicator unit function as hands-free Bluetooth communication devices, with the input device being a microphone and the output device being a speaker.
[0021] The system includes a button installed on a steering wheel or in the interior of the vehicle, directly linked to the second communicator unit. Activation of this button initiates communication between the second communicator unit and the one or more first communicator units, enhancing user convenience and accessibility during interactions with external service locations.
[0022] In an aspect, the predefined locations, associated with fast-food services, facilitate the establishment of a secured communication channel. This channel enables voice communication between the fast-food service operator and vehicle occupants, empowering occupants to select, customize, and order products. The operator can confirm availability and preferences, update order status, and receive payments from the occupants. Further, the first communicator units and second communicator unit are interconnected with a payment server, various point-of-sale (POS) transaction devices, and a POS ordering device, facilitating seamless communication and transaction processes within the system.
[0023] In another aspect, the one or more predefined locations are one or more billboards installed on a road, establishing secured communication channels while the vehicle is in motion. This enables the first communicator units to broadcast billboard-related voice information to the second communicator unit of the vehicle. The second communicator unit is configured to store, categorize, and allow occupants to filter and play this information, both in real-time and across predefined distances traveled by the vehicle.
[0024] In another aspect, a method for in-vehicle communication is disclosed where a broadcasting beacon module of one or more first communicator units positioned at predefined locations generates and broadcasts one or more credential signals within a predefined range around the corresponding first communicator unit. Further, the beacon listener module of a second communicator unit attached to the vehicle detects the broadcasted credential signals when the vehicle is within the predefined range. Upon detection, the second communicator unit establishes a secured communication channel with the respective first communicator unit. If the predefined locations are associated with a fast-food service, the method enables various interactions, including voice communication between the fast-food operator and vehicle occupants, order placement and customization, order status updates, and payment processing.
[0025] Alternatively, if the predefined locations are billboards installed on a road, the method allows the first communicator units to broadcast voice information associated with the billboards to the second communicator unit, which then stores, categorizes, and allows vehicle occupants to access and interact with this information in real-time.
[0026] Accordingly, the proposed system and method streamlines drive-through service, enabling quick, contactless orders without window or door opening. It integrates seamlessly into vehicle systems for hands-free operation, enhancing safety and convenience. By improving order accuracy and processing efficiency, it boosts business revenue while providing personalized information exchange with roadside billboards.

DETAILED DESCRIPTION
[0035] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
[0036] The present disclosure relates to wireless voice communication, and in particular, relates to an in-vehicle voice communication system and method thereof to facilitate seamless interaction between vehicle occupants and external service locations.
[0037] FIG. 1A illustrates an exemplary block diagram representation of proposed in-vehicle system 100 (interchangeably referred to as system 100, hereinafter), in accordance with the embodiments of the present disclosure. As shown, the system 100 includes one or more first communicator units 110 (collectively referred to as first communicator units 110, and individually referred to as first communicator unit 110, hereinafter) positioned at one or more predefined locations, and a second communicator unit 120 installed in a vehicle 104. The first communicator units 110 are strategically placed at predefined locations including but not limited to, service locations such as drive-throughs for food and beverages, or other facilities along roadsides.
[0038] Each communicator unit 110 is equipped with a broadcasting beacon module 112 configured to transmit one or more credential signals within a predefined range around the corresponding first communicator units 110. These credential signals include Bluetooth Low Energy (BLE) signals but are not limited to the like. In an embodiment, the credential signals include credentials associated with the broadcasting beacon module 112. These signals serve as identifiers or markers and facilitate communication initiation with the second communicator unit 120.
[0039] Additionally, in an embodiment, the first communicator units 110, and the second communicator unit 120 are hands-free Bluetooth communication devices. This facilitates seamless and wireless communication between the first communicator units 110 and the second communicator unit 120, facilitating the exchange of audio data without the hassle of physical connections. For instance, operator 106 at the service location and driver 102 or occupant of the vehicle 104 can interact hands-free, minimizing distractions and enhancing safety, especially in a vehicle environment where manual operation of devices may pose risks.
[0040] In an embodiment, the second communicator unit is an in-vehicle infotainment (IVI) system, but not limited to the like and configured to enable seamless communication between occupants 102 of the vehicle 104 and the first communicator units 110.
[0041] In an embodiment, each first communicator units 110 include an input device 114 and an output device 116 (also, referred to as first input device 114, and first output device 116, herein), and the second communicator unit includes an input device 124 and an output device 126 (also, referred to as a second input device 124, and a second output device 126, herein). The first input device 114 and the second input device 124 are microphones that are configured to capture and transmit audio data to the respective communicator unit. Additionally, the first output device 116 and the second output device 126 are speakers that are configured to receive and play audio data received from the respective communicator unit. Further, the first output device 116 and the second output device 126 may also be a display device that is configured to convert the audio data received from the respective communicator unit into a visual format for displaying over the display device.
[0042] In an exemplary embodiment, the first and second input devices 114, 124, and the first and second output devices 116, 126 are a hands-free profile (HFP) or Advanced Audio Distribution Profile (A2DP) but are not limited to the like. In an exemplary embodiment, the second input device 124 and the second output device 126 include an audio sub-system configured with the vehicle 104.
[0043] Additionally, the second communicator unit 120 is equipped with a beacon listener module 122 that detects the credential signals transmitted by the broadcasting beacon module 112 of the first communicator units 110 when the vehicle 104 is within the predefined range of these first communicator units 110. Upon detection of these credential signals, the second communicator unit 120 establishes a secured communication channel with the respective first communicator unit 110. The beacon listener module 122 detects and listens to the credential signals and correspondingly obtains credentials associated with the first communicator unit 110 broadcasted within the signals. In an example, the beacon listener module 122 is configured to detect and listen to the one or more signals broadcasted when the vehicle 104 configured therewith enters the predefined detection range of the broadcasting beacon module 112.
[0044] In an embodiment, the operator 106 comprises but is not limited to, the person taking orders at a fast-food drive-through, a patrol vehicle police officer, and a service facility officer on a road. In an embodiment, when the one or more signals are detected by the beacon listener 122, an audio connection is established to initiate a voice communication between the operator 106 of the first communicator unit 110 and the driver 102 and/or passengers within the vehicle 104. In an example, the voice communication between the operator 106 and the driver 102 may facilitate the placement of an order for the purchase of one or more products from the operator 106 at a drive-through or at other locations. In an exemplary embodiment, the purchase of products includes, but is not limited to fast food, food items, beverages, daily supplies, groceries, and other necessities.
[0045] In an embodiment, the system 100 includes an audio routing unit 130 configured to manage and direct audio data between different devices or components within the system 100. In an embodiment, the audio routing unit 130 is configured to route the audio data to the appropriate destinations, such as between the first input device 114 to the second output device 126, and the second input device 124 to the first output device 116. The audio routing unit 130 is configured to transmit the audio data between the first communicator unit 110 and the second communicator unit 120.
[0046] In an embodiment, the system includes a button (not shown) installed on the steering wheel of the vehicle and operably connected to the second communicator unit 120. However, the button or an additional button may also be installed in the interior of the vehicle and further operably connected to the second communicator unit 120. When the button is pressed, this triggers the second communicator unit 120 to initiate communication with the first communicator units 110. For instance, the button serves as a convenient means for the driver to activate communication between their vehicle and first communicator units 110 without the need for manual intervention elsewhere in the vehicle.
[0047] Further, in an embodiment, the system includes a human-machine interface (HMI) device installed in the interior of the vehicle and further operably connected to the second communicator unit 120. When a button on the HMI device is pressed, this triggers the second communicator unit 120 to initiate communication with the first communicator units 110. In an exemplary embodiment, the HMI device may be a mobile phone of the occupant. Further, the HMI device may also be a touchscreen infotainment system of the vehicle. For instance, the HMI device serves as a convenient means for the driver to activate communication between their vehicle and first communicator units 110 without the need for manual intervention elsewhere in the vehicle
[0048] In an example, when the vehicle is equipped with a digital cockpit, an automated connection between the vehicle and the first communicator unit 110 is facilitated either by pressing the button on the Steering Wheel Controls (SWC) or via a touch screen interface or HMI device of the vehicle. For instance, as the vehicle approaches a fast food facility, a driver 102 or occupant (passenger) initiates the connection process by pressing a dedicated button on the steering wheel or by using the touch screen interface inside the vehicle. Once initiated, if the fast food facility is equipped with the first communication unit, operator 106 at the service location automatically connects to the driver 102 by audio. Consequently, the driver 102 communicates with the operator 106 without needing to open the window, utilizing the microphone and speaker of the second communicator unit 120 installed within the vehicle. This enables hands-free communication, enhancing convenience and safety for the driver 102 and occupants of the vehicle while interacting with the first communicator unit at the fast food facility.
[0049] In another example, if driver of the vehicle notices information displayed on road signs or billboards while driving on a road and decides to capture the billboard information by pressing the Steering Wheel Controls (SWC) button, the digital cockpit system reacts based on the information transmitted by the corresponding Bluetooth Low Energy (BLE) beacon (i.e. broadcasting beacon module 112). For instance, if the signal indicates "Tune Tuner to FM 101 channel to listen to Tourist Info," the digital cockpit system retrieves the channel number in this case, FM 101, and automatically tunes the Tuner to that specific channel. This enhances user experience by effortlessly providing relevant information without requiring manual intervention.
[0050] In another example, the second communicator unit 120 is configured in a police patrol vehicle with the officer intending to stop and interrogate a driver or an occupant of another vehicle. During a traffic stop or interrogation situation, the police officer utilizes the first communicator unit 110 to establish communication with the driver or occupants of the other vehicle. This allows the officer to communicate with the individuals without the need to physically approach the vehicle or open the window, thereby maintaining a safer distance and potentially reducing confrontation or escalation of the situation. By using the first communicator unit 110, the police officer effectively communicates with the driver or occupants of the other vehicle, requests documentation, provides instructions, or conducts necessary inquiries, all while remaining within the confines of their own patrol vehicle.
[0051] Referring to FIG. 1B, system 100 depicts interaction between a Point of Sale (POS) system and In-Vehicle Infotainment (IVI) system. The POS system represents the first communicator unit 110 and the IVI system represents the second communicator unit 120. These POS and IVI systems are equipped with IoT feature solutions running on either Android or Linux operating systems, enabling seamless integration and functionality. The POS system, positioned at predefined locations such as fast-food services includes components for broadcasting and receiving audio signals. This also includes a connectivity app, connectivity service, and a BLE (Bluetooth Low Energy) stack, facilitated by a BLE CSR 4.0 dongle, which allows for secure communication with the IVI system in the vehicle.
[0052] The IVI system incorporates similar components to ensure compatibility and efficient communication. This includes a connectivity app and connectivity service, a BLE stack, and a BLE CSR 4.0 dongle, enabling the connectivity to establish a secure communication channel with the POS system upon detecting broadcasted credential signals. The system uses microphones and speakers in both the POS and IVI systems to capture and transmit audio data, facilitating voice communication between the vehicle occupants and the service operators at the predefined locations. This supports a variety of applications, enhancing convenience and efficiency of in-vehicle services. The seamless communication enabled by the BLE technology ensures a hands-free, contactless interaction, improving the overall user experience and operational efficiency.
[0053] FIG. 2 illustrates an exemplary network architecture 200 of an implementation of the proposed system 100, in accordance with the embodiments of the present disclosure. As shown, the system 100 is connected to external systems 150 including, but not limited to, a POS ordering device 152, one or more point-of-sale (POS) transaction devices 154 (interchangeably referred to as POS transaction devices 154, hereinafter), and a payment server 156, via a communication network 140. In an embodiment, the first communicator unit 110 and the second communicator unit 120 are connected to external systems 150 via the communication network 140.
[0054] In an embodiment, the driver 102 also employs or is provided with an electronic device 108 to communicate with the external systems 150. The external systems 150 of the present disclosure may be optional in case the POS ordering system 156 has a connection to any other existing external payment systems. In an embodiment, the communication network 140 may be a wired communication network or a wireless communication network.
[0055] In an embodiment, the external systems enable the second communicator unit 120 or the first communicator unit 110 to place orders by transmitting one or more data packets thereto. In an embodiment, the driver 102 uses the electronic device 108 to load and place orders via an interface by transmitting a first set of data packets to the POS ordering device 152 and receiving a second set of data packets in response. The first set of data packets includes details such as the items requested, quantities, and any specific preferences or customizations. For example, if the driver of the vehicle is picking up food orders from a restaurant, the first set of data packets sent to the POS ordering device 152 might include the list of items to be picked up, along with any specific instructions or dietary restrictions. Additionally, the second set of data packets includes confirmation of the order, estimated preparation time, and any other relevant information. For example, if a driver places an order for food pickup, the second set of data packets received from the POS ordering device might confirm the order and provide an estimated time for pickup.
[0056] In an embodiment, the operator 106, using the first communicator unit 110 or mobile device, transmits a third set of data packets to the POS transaction devices 154 to place a record of the transaction taking place between the operator 106 and the driver 102. The third set of data packets includes details such as the item or service purchased, quantity, price, and any applicable taxes or discounts.
[0057] In an embodiment, the payment server 156 is provided with a fourth set of data packets with requisite information to execute a transaction between the operator 106 and the driver 102. The fourth set of data packets includes details such as the transaction amount, payment method, and any additional information necessary for processing the payment. For instance, payment server 156 may be a centralized server maintained by a payment processing company or a specific server managed by the organization that owns the system. An example of a payment server is a backend server used by PayPal to process online payments. When a driver or occupant makes a purchase using any payment platform, the payment server handles the transaction, verifies payment details, and communicates with banks or other financial institutions to authorize the payment.
[0058] In an example, the external systems 150 is configured to execute transactions on receiving one or more Application Programming (API) requests along with the data structure in the required format containing all necessary information for the transaction. This ensures that transactions are processed accurately and efficiently.
[0059] In an embodiment, FIG. 2 also depicting GATT (Generic Attribute Profile) interaction 160 between GATT client 162 and GATT server 164 that illustrates process of service discovery, request handling, and data transfer within Bluetooth Low Energy (BLE) framework. The system 100 utilizes the GATT Client 162 and GATT Server 164 to streamline order and payment process.
[0060] At block 166, when the vehicle 104, equipped with GATT Client 162, approaches a predefined location like a fast food service, the GATT client 162 initiates a service discovery process to identify the services offered by the GATT Server 164 at the location. This service discovery process includes GATT client 162 sending a request to the GATT server 164 to discover available services, further the GATT server 164 lists as service characteristics, including values and descriptors. These characteristics define kind of data or functionality is provided by the GATT server 164, such as menu options, customization features, and order status updates.
[0061] At block 168, once the service discovery process is complete, the GATT client 162 populates a table with the available services of peer server. This table includes detailed information about each service's characteristics, enabling the GATT client 162 to understand actions to be performed. For example, in a fast food service scenario, this table might include services for browsing menu, customizing orders, checking order status, and processing payments.
[0062] Continuing further, at block 170, the GATT client 162 transmits client requests to the GATT server 164 corresponding to interactions of the vehicle occupants. These client requests might involve selecting menu items, customizing an order, or requesting an update on the order status.
[0063] Continuing further, at block 172, the GATT server 164 responds to these requests by providing the requested information or performing the requested actions. This response might include sending detailed menu information, confirming order details, or providing real-time updates on the order's preparation status. Additionally, at block 174, the GATT server 164 switch on indications or notifications to keep the GATT client 162 updated about any changes or updates in real-time. For instance, if there is a delay in the order preparation, the GATT server 164 notifies the GATT client 162, ensuring that the vehicle occupants are informed without needing to send a separate request.
[0064] Furthermore, at block 176, the GATT server 164 initiates data transfers to the GATT client 162, pushing important updates or information automatically, this may include sending a notification when the order is ready for pickup, ensuring a smooth and efficient transaction process.
[0065] FIG. 3 illustrates an exemplary sequence diagram 300 of the interface between the first communicator unit 110 and the second communicator unit 120, in accordance with the embodiments of the present disclosure. At step 302, the first communicator unit 110 is configured to broadcast one or more credentials signals over a predefined detection range. In an example, the predefined detection range is indicative of and covers the premises of the drive-through. At step 304, the second communicator unit 120 is configured to detect and listen the one or more credentials signals and correspondingly obtain credentials associated with the first communicator unit 110 broadcasted within the credentials signals. In an example, the beacon listener module 122 is configured to detect and listen to the credentials signals broadcasted when the vehicle configured therewith enters the predefined detection range of the broadcasting beacon module 112. In an embodiment, the driver 102 uses the credentials to identify the operator 106 associated with the first communicator unit 110. Identification of initiator of communications with Driver (IID) is used to inform the driver who is communicating to acknowledge the connection either by the “button” or Steering Wheel Controls (SWC) or via a touch screen interface or automatically (can be a feature setting in the vehicle). Thereafter, the driver 102 grants permission to establish a connection between the first communicator unit 110, and the second communicator unit 120.
[0066] At step 306, the first communicator unit 110 and the second communicator unit 120 are configured to establish a connection to enable voice communication therebetween. In an embodiment, the connection is established by connecting the second communicator unit 120 to a wireless access point (WAP) associated with the first communicator unit 110. In such embodiments, the first communicator unit 110 is provided with a captive portal associated with WAP.
[0067] At step 308, the driver 102 and the operator 106 exchange one or more voice messages via the first communicator unit 110 and the second communicator unit 120 respectively to place an order. In an embodiment, the driver 102 records and transmits their voice messages via the second input device 124, which are conveyed to the operator 106 via the first output device 116. Likewise, the operator 106 speaks into the first input device 114 and conveys voice messages to the driver 102 via the second output device 126. In an embodiment, the driver 102 also interfaces with one or more of the external systems 150 via the electronic device 108 to make payments and complete transactions. In an embodiment, once the driver’s order is placed and executed, the driver 102 picks up the purchased product from the drive-through.
[0068] FIG. 4 illustrates exemplary steps involved in proposed method 400 for in-vehicle communication, in accordance with the embodiments of the present disclosure. At step 402, the method 400 includes the generation and transmission of one or more credential signals by a broadcasting beacon module 112 of one or more first communicator units 110 positioned at one or more predefined locations. These credential signals are broadcasted within a predefined range around the corresponding first communicator unit 110. This predefined range is determined by the capabilities and specifications of the broadcasting beacon module 112, defining distance over which the signals can effectively propagate. For instance, the predefined range can be 100 meters. The one or more predefined locations are associated with service facilities such as fast-food service or the like, and are selected strategically to accommodate the needs of drivers and occupants of vehicles passing through.
[0069] Continuing further, at step 404, the method 400 detects one or more broadcasted credential signals, by a beacon listener module 122 of a second communicator unit 120 attached in a vehicle 102. When the vehicle enters the predefined range of the corresponding first communicator unit 110, the beacon listener module 122 actively listens for the broadcasted credential signals emitted by the broadcasting beacon module 112 associated with the first communicator unit 110. This detection process occurs automatically when the vehicle is within range, indicating its proximity to the service facility or location equipped with the first communicator unit 110.
[0070] Continuing further, at step 406, the method 400 establishes a secured communication channel between the second communicator unit 120 and the respective first communicator unit 110 at the service facility. This establishment occurs upon the detection of the broadcasted credential signals by the second communicator unit 120, facilitated by the beacon listener module 122. Once the credential signals are detected, indicating that the vehicle is within the predefined range of the first communicator unit 110, the method proceeds to establish a secure communication link between the service facility and the vehicle.
[0071] Furthermore, upon the successful establishment of the secured communication channel, the method enables voice communication between the operator 106 of the fast-food service and occupants 102 of the vehicle.
[0072] Continuing further, the method 400 enables the occupant 102 to select, customize, and place an order for one or more products at fast-food service providers enhancing the convenience of the ordering process. Additionally, enabling the operator 106 to confirm availability and customization preferences for the order selected by the occupant 102. Further, enabling the occupants 102 to request an update on the status of their placed order, and enables the operator 106 to update the status of the placed order to occupants 102. Furthermore, enabling the occupants 102 to make a payment for the placed order completing the transaction seamlessly. These functionalities collectively contribute to an enhanced customer experience, optimizing the ordering process and facilitating effective communication and transaction management between occupants and the fast-food service provider.
[0073] In another embodiment, the predefined locations are one or more billboards installed along a road, and the method 400 includes the steps of enabling first communicator units 110 positioned at these billboards to broadcast voice information associated with the corresponding billboards to the second communicator unit 120 of the vehicle. This broadcasting occurs once the secured communication channel is established during the movement of the vehicle on the road. Further, the method 400 includes the step of storing and categorizing, by the broadcasted voice information received from the billboards by the second communicator unit 120. This information is stored across a predefined distance traveled by the vehicle on the road, allowing for organized retrieval and playback. The predefined distance can be 100 meters or the like.
[0074] Furthermore, occupants 102 of the vehicle are allowed by the second communicator unit 120 to filter and play the stored broadcasted voice information and/or play the broadcasted voice information in real-time as the vehicle progresses along its route. This enhances the driving experience by providing occupants with relevant and timely information from roadside billboards in an easily accessible manner, thereby enriching their journey.
[0075] FIG. 5 illustrates an exemplary representation of the proposed system and method implemented for a fast-food drive-through application, in accordance with the embodiments of the present disclosure. Fast food drive-throughs are very popular in many countries, and on an average workday people take at least two stops for quick food or coffee break. Average time of fast-food servicing based on market search may be about 256 seconds. If the service time is reduced by about 10 seconds, a significant revenue increase is estimated. The service time reduction and quality audio improvement by implementing the system 100 and method 400 of the present disclosure allows the fast-food networks to service a greater number of customers in a day, leading to increased revenue generation.
[0076] As illustrated in FIG. 5, a fast-food implementation 500 of the proposed system 100 may include the vehicle 104 operated by the driver 102. The driver 102 may pass through the service location indicative of a fast-food drive-through 502 and interact with the operator 106 of said fast-food drive-through 502 to place an order for purchasing products, like, but not limited to food items, beverages, etc. The system 100 enables audio communication or interaction between the driver 102 and the operator 106.
[0077] For instance, as the driver 102 approaches the fast-food drive-through 502 on vehicle 104, the beacon listener module 122 associated with the in-vehicle communicator unit 120 in the vehicle 104 listens to the one or more signals broadcasted by the broadcasting beacon module 112. The beacon listener module 122 receives the credentials associated with the broadcasting beacon module 112. The second communicator unit 120 establishes an audio communication with the first communicator unit 110, based on the credentials in the one or more signals. The driver 102 and the operator 106 engage in voice communication using the second input device 124 the second output device 126, and the first input device 114 and the first output device 116 respectively. Thereafter, the driver 102 talks to the operator 106 to place the order that may be collected from the pickup location in the fast-food drive-through 502. With the system of the present disclosure, the driver 102 talks to the operator 106 without opening the car window and by use of internal car microphone and speakers. In some examples, the driver 102 may make payments for the order using the electronic device 108 by communicating with external system(s) 150. Since the voice communication takes place through electronic devices where connection there between is established as the vehicle 104 approaches the operator 106 in the service location, the average ordering time at the fast-food drive-through 502 may be reduced.
[0078] FIG. 6 illustrates an exemplary representation of the proposed system and method been implemented in billboards on a road, in accordance with the embodiments of the present disclosure.
[0079] Referring to FIG. 6, in another embodiment, the predefined locations are one or more billboards (602, 604, 606) installed along a road. In such embodiments, the first communicator units 110 may be installed on the billboards (602, 604, 606). During the movement of the vehicle on the road, the establishment of the secured communication channel enables the first communicator units 110 positioned at these billboards to broadcast voice information associated with the corresponding billboards onto the second communicator unit 120 installed in the vehicle. Additionally, the second communicator unit 120 is configured to store and categorize the broadcasted voice information received from the billboards across a predefined distance traveled by the vehicle on the road. This allows for organized storage and retrieval of the information. Furthermore, occupants of the vehicle are provided with the capability to filter and play stored broadcasted voice information, or alternatively, play the broadcasted voice information in real-time as the vehicle progresses along its route. This aspect of the system enhances the driving experience by providing occupants with relevant and timely information from roadside billboards, contributing to a more informative and engaging journey.
[0080] In an exemplary embodiment, the Software as a Service (SaaS) feature operates on a subscription-based model, fundamentally transforming automotive landscape. Original Equipment Manufacturers (OEMs) forge strategic alliances with publishers of information, establishing a dynamic ecosystem where revenue is jointly generated based on information usage. For example, drivers subscribing to a service could access real-time traffic updates, roadside assistance, or exclusive offers from service facilities during travel, all through their vehicle's infotainment system. This symbiotic relationship ensures a continuous revenue stream for both OEMs and content providers, while simultaneously enhancing driving experience for drivers/occupants. This symbiotic relationship ensures a continuous revenue stream for both OEMs and content providers, while simultaneously utilizing data and services customized to needs of customers (i.e. occupants, here) to enhance driving experience and drive customer loyalty and revenue growth within the automotive industry.
[0081] Thus, the proposed system and method streamlines drive-through service, enabling quick, contactless orders without window or door opening. It integrates seamlessly into vehicle systems for hands-free operation, enhancing safety and convenience. By improving order accuracy and processing efficiency, it boosts business revenue while providing personalized information exchange with roadside billboards.
