These files contain vehicle parameters and user-selectable options, ensuring that the display content is readily accessible and easily adjustable. Moreover, the system (100) incorporates a human-machine interface (HMI) (106) designed for translating one or more design sketches into digital designs. These digital designs are then exported to an HMI cross-platform tool (107) for seamless integration with the micro controller (103). This integration ensures that the digital dashboard (101) functions cohesively, providing a robust and flexible user interface for two-wheeler users. Additionally, the Human-Machine Interface (HMI) (105) includes testing and validating the digital designs on the micro controller (102).
[0034] In an embodiment of the present invention, the application layer (104) is integrated with a user experience algorithm for processing data from the memory (104) and dynamically changing the display language of the entire main and setting screens based on the user's language selection.
[0035] FIG 2 illustrates a block diagram depicting the process steps involved in implementing the multi-lingual feature for displaying cluster parameters in a two-wheeler digital dashboard, according to an embodiment of present invention. The process (200) of implementing the multi-lingual feature for displaying cluster parameters in the two-wheeler digital dashboard begins with designing the HMI screens using the Photo-shop, creating both the main screen with instrument cluster features and the setting screen with options to select and control certain information within the cluster in step (201). Once the design is completed, all the images are exported to an HMI cross-platform tool that supports the controller, facilitating integration into the system in step (202). Subsequently, the image files created for the main and setting screens are stored in the dedicated memory for efficient access in step (203). The output file (.h / C++ files) is then added to the application layer, enabling the implementation of the user experience algorithm in step (204). The algorithm is responsible for extracting data from memory and processing vehicle information according to the application-defined logic, ensuring smooth functionality. Additionally, the multilingual algorithm is integrated into the application layer to dynamically change screens based on the selected language option. Furthermore, the micro controller is programmed to provide options for selecting different languages such as Kannada, Hindi, Tamil, and German, expanding accessibility. Ultimately, the entire main and setting screen adapts and displays the vehicle information in the user-selected language through digital dashboard equipped with TFT display, making it easier for users to understand the various options available in the two-wheeler dashboard.
[0036] FIG 3 illustrates the flowchart depicting the language selection mechanism, according to an embodiment of the present invention. The language selection mechanism (300) involves a series of coordinated steps designed to facilitate user interaction and ensure dynamic adaptation of display language. The process (300) begins with allowing the user to navigate through various language options using a set of user interface (UI) elements in step (301). These UI elements include buttons, touchscreens, or other input devices that make the selection process intuitive and user-friendly. Further, upon the user selecting their desired language in step (302), an embedded algorithm within the system activates. This algorithm is programmed to retrieve and process the necessary image files and data from the external flash memory. The external flash memory contains a comprehensive repository of image files that represent the main and setting screens, each with the capability to display vehicle parameters and user-selectable options in multiple languages. Once the relevant files and data are retrieved, the system dynamically adapts the display screens in step (303). This involves changing the display language for vehicle parameters such as speed, odometer readings, range estimation, trip meters, battery status, temperature, and indicator signals. The adaptation process ensures that the entire interface, including all main and setting screens, reflects the user-selected language, thereby enhancing user understanding and accessibility of the vehicle’s information and functions. This seamless integration of the multilingual feature ensures that users can interact with their vehicle’s dashboard in their preferred language, improving the overall user experience.
[0037] FIG 4 illustrates a flowchart depicting the micro controller and associated data processing functionalities, according to an embodiment of the present invention. The micro controller and associated data processing functionalities comprises the steps of receiving vehicle data from an Electronic Control Unit (ECU) via a Controller Area Network (CAN), enabling real-time monitoring of vehicle parameters such as speed, odometer reading, battery status, and temperature in step (401). Further, processing the received vehicle data using the application layer algorithm implemented in the system's application layer in step (402). The algorithm ensures compatibility with the digital dashboard, incorporating the Thin-Film Transistor (TFT) display capable of supporting Low Voltage Differential Signaling (LVDS) and Red-Green-Blue (RGB) formats. The processed data is then displayed on the TFT display in the language selected by the user. Furthermore, storing screen data, including image files representing main and setting screens, in external flash memory in step (403). The stored data is retrieved based on user interactions, allowing dynamic adaptation of the display to show vehicle parameters and other relevant information according to user preferences.
[0038] In an embodiment of the present invention, the advanced multi-lingual cluster display system (100) for two-wheeler dashboards, transitions from traditional analog and digital displays to a Thin-Film Transistor (TFT)-based instrumental cluster. This system (100) introduces flexibility and customizability in display designs, addressing user needs by incorporating a multi-lingual interface. The primary objective of the present invention is to connect users more effectively with vehicle diagnostics and enhance their overall driving experience by enabling the selection of a preferred display language. This customization ensures that all screens within the two-wheeler instrumental cluster accurately reflect the selected language, improving accessibility and user comprehension.
[0039] In an embodiment of the present invention, the system (100) comprises both controller-based hardware and software, engineered to perform dedicated functionalities.

The UI/UX design of the two-wheeler instrumental cluster includes multiple screens that display cluster features and user options. The multi-screen setup is dependent on available memory (105) and the options provided. The designed images are exported to the HMI cross-platform tool (107) to create wire frames, defining the structure and key elements corresponding to the listed features and user options. These designed screens are stored in the memory (105), and the HMI cross-platform tool (107) generates output files that are exported to the application layer (104) of the micro controller (103). The micro controller (103) architecture is designed to receive vehicle data from the Electronic Control Unit (ECU) via a Controller Area Network (CAN) and subsequently update the cluster display. Moreover, a software algorithm processes and displays the received data in the user-selected language using an application layer algorithm. The multi-lingual algorithm is integrated within the application layer (104) of the micro controller (103), allowing the system to dynamically change screens based on the user's language selection. Upon selection of a particular language, the micro controller (103) retrieves data from the stored memory (105), updates the relevant parameters, and displays the required information across all designed screens within the two-wheeler instrumental cluster.
