Vehicle Display Control Device for Adaptive Permission Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, occupants may not voluntarily switch the permission or forbiddance of target controls, such as traction control, based on the vehicle's situation, leading to inappropriate control execution.
Innovation Solution
A display control device with a processor that recognizes vehicle conditions using internal sensors and determines whether to prompt the occupant to switch the permission or forbiddance of target controls by displaying specific information on a display unit, allowing the occupant to easily recognize and adjust control settings based on the vehicle's situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system automatically manages control permissions, then the complexity of manual operation is reduced, but the adaptability to varying vehicle situations deteriorates
Solution Approach 1:
The system continuously monitors vehicle conditions through sensors and provides feedback to the control unit. When the control unit detects that current control permissions do not match the actual vehicle situation, it automatically issues notifications to the occupant and adjusts permissions accordingly, creating a closed-loop feedback system that combines automatic monitoring with adaptive response
Solution Approach 2:
The system enables occupants to easily switch control permissions through simple notification responses rather than complex manual operations. The automatic notification and confirmation mechanism allows occupants to maintain control over permissions with minimal effort, making the system self-serve the occupant's intent while adapting to vehicle conditions
2Adaptability or versatility
If the system continuously monitors vehicle conditions and automatically notifies occupants, then the adaptability to vehicle situation is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it monitors vehicle conditions through sensor inputs, compares current permissions with actual conditions, determines when notifications are necessary, issues notifications to occupants, and executes permission changes. This multi-functional design consolidates complex operations into a single control unit, managing adaptability without proportionally increasing overall system complexity
Solution Approach 2:
The system pre-establishes the framework for automatic monitoring and notification before vehicle operation begins. Sensors are configured to continuously monitor conditions, and the control unit is pre-programmed with the logic to compare permissions against actual conditions and issue appropriate notifications, eliminating the need for complex real-time decision-making during operation
3Reliability
If the system prompts occupants to switch permissions based on vehicle conditions, then the appropriateness of control execution is improved, but the loss of time for occupant response occurs
Solution Approach 1:
The control unit periodically checks whether current control permissions match actual vehicle conditions and issues notifications at appropriate intervals. This periodic monitoring ensures that permission adjustments are made timely without requiring continuous occupant attention, balancing reliability with minimal time loss
Solution Approach 2:
The system proactively identifies mismatches between permissions and vehicle conditions and issues notifications before inappropriate control execution occurs. By detecting and alerting occupants in advance, the system prevents problematic situations rather than reacting to them, reducing the time occupants need to respond to critical issues
Data Source
AI summary
A display control device for a vehicle includes a processor. The processor is configured to switch permission or forbiddance of execution of target control for a predetermined function by an operation of an occupant, acquire a permission status indicating permission or forbiddance of the execution of the target control, recognize a condition of the vehicle, determine whether to propose a first operation or a second operation to the occupant based on the permission status and the condition of the vehicle, and display first information related to the first operation on a display unit provided in the vehicle when the processor determines to propose the first operation to the occupant, or display second information related to the second operation on the display unit when the processor determines to propose the second operation to the occupant.
