Vehicle Digital Instrument Panel Personalization via External Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle instrument panels lack the ability to display user-specific information and allow customization, limiting personalization and convenience for drivers.
Innovation Solution
A vehicle system that includes a display unit and a controller to show user identification information, such as signatures, and allows for registration, deletion, and modification of this information through an input unit, with communication with an external terminal for image processing and design changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a digital-type instrument panel is used to display various information, then the versatility of information display is improved, but the ability to show user-specific personalized information deteriorates
Solution Approach 1:
The system performs preliminary actions by storing user identification information (signatures, pictures) in advance in the storage unit. When a user approaches or enters the vehicle, the controller retrieves and displays the pre-stored personalization data on the digital instrument panel, enabling seamless personalization without requiring real-time input from the user.
Solution Approach 2:
The system creates visual copies of user identification information (signatures and pictures) and displays them on the digital instrument panel. The terminal device transmits digital copies of these personalization elements to the vehicle system, which then renders them on the display, allowing users to see their personal information displayed without physically present in the vehicle.
2Device complexity
If an analog-type instrument panel is used, then the simplicity of the display system is improved, but the ability to display diverse and personalized information deteriorates
Solution Approach 1:
The digital instrument panel serves multiple functions: it displays traditional meter information (speed, RPM) and simultaneously displays personalized user information (signatures, pictures). The controller manages different display modes, allowing the same hardware to fulfill both conventional and personalized display needs, making the system universally applicable to various information types.
Solution Approach 2:
The display system dynamically changes its content based on user presence and input. The controller adjusts what is displayed on the digital instrument panel in real-time - showing meter information when no user is detected, and switching to personalized information when a user approaches or inputs their identification, making the system adaptable rather than static.
3Ease of operation
If user identification information is stored and displayed in the vehicle system, then the personalization capability is improved, but the security risk of unauthorized access deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the terminal device receives confirmation from the vehicle system about successful transmission of user identification information. The controller verifies received data before storing, and the system provides feedback loops for authentication, ensuring that only authorized users can access and modify their personalization data.
Solution Approach 2:
The terminal device acts as an intermediary between the user and the vehicle system. It handles the transmission and initial verification of user identification information before it reaches the vehicle's storage unit, providing an additional layer of security and preventing direct unauthorized access to the vehicle's personalization database.

AI summary
A vehicle includes a display unit, and a controller configured to control the display unit to display user identification information such as an emblem and a signature, as an intro image. A user thereby can feel a sense of pride and ownership in his/her own vehicle, and develop a sense of attachment and brand loyalty for his/her own vehicle.
