Vehicle Display Control With Event-Based Home Button Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack a flexible and user-centric interface that allows occupants to easily control multiple displays within a vehicle, with limited adaptability to different users and scenarios, and do not effectively restrict access to applications by passengers.
Innovation Solution
A vehicle control device with a communication unit and processor that dynamically controls display home buttons based on events, user identification, and occupancy, allowing for customizable icon lists and region management on multiple displays, enabling personalized interfaces and restricting access to certain applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed number of home buttons are provided in fixed positions, then the device structure is simple, but the adaptability to different users and scenarios is poor
Solution Approach 1:
The patent implements dynamic home buttons that change their number, position, and associated icon lists based on detected events (such as user entry, seat occupancy, or system states). This allows the interface to adapt to different users and scenarios without requiring multiple physical buttons for each possible configuration.
Solution Approach 2:
The home buttons serve multiple functions: they can be displayed on different displays, different numbers of home buttons can be shown based on the situation, and each home button can be associated with different icon lists depending on the event. This multi-functionality resolves the contradiction by making a simple button structure highly adaptable.
2Adaptability or versatility
If multiple displays are provided in the vehicle, then the information display capability is enhanced, but the complexity of controlling and managing display regions increases
Solution Approach 1:
The patent divides the vehicle's display system into multiple independent displays, each capable of showing its own home button and icon list. This segmentation allows each display to be managed independently, reducing the overall control complexity while maintaining enhanced information display capability across multiple screens.
Solution Approach 2:
Each display can have different home buttons and icon lists tailored to its location and function (e.g., driver display vs. passenger display). This local quality approach allows customized control for each display region without requiring complex centralized management of the entire multi-display system.
3Ease of operation
If all applications are accessible to all occupants, then the ease of operation is improved, but the safety is compromised due to unauthorized access to critical functions
Solution Approach 1:
The patent associates different icon lists with different home buttons based on user identity and position. For example, the driver's home button may have access to all applications including critical functions, while passenger home buttons have restricted access to only safe applications. This local quality differentiation maintains ease of operation for authorized users while ensuring safety through restricted access.
Solution Approach 2:
The home button acts as an intermediary that mediates access to applications. Instead of direct access to all applications, users must go through their assigned home button, which filters and controls what applications are accessible based on user role and safety requirements.

AI summary
Provided are a vehicle control device for controlling one or more displays provided in a vehicle, and a vehicle including the same. The vehicle control device includes a communication unit performing communication with the one or more displays, and a processor controlling, when an event occurs, the one or more displays to display a home button corresponding to the event using the communication unit, wherein the home button is configured to display a preset icon list in response to a touch applied to the home button, and the preset icon list is varied according to the event.
