Vehicle Key Memory for Portable State Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicles become increasingly complex, users face challenges in managing advanced control systems across different vehicles, requiring them to adjust settings each time they use or switch vehicles, and often need to revert to base settings upon key-off and key-on, leading to inconvenience and complexity.
Innovation Solution
A system that uses a processor to detect a vehicle key, display key identification, and store predefined vehicle system and state settings in a key memory, allowing users to load and save settings directly to the key, enabling portable and persistent control over vehicle systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle settings are stored in the vehicle's base control system, then settings can be maintained during operation, but users must revert to base settings upon key-off and key-on, and cannot easily transfer settings between vehicles
Solution Approach 1:
The patent extracts vehicle settings from the vehicle's base control system and stores them in an external key memory device. This allows settings to be portable between vehicles while maintaining ease of operation through automatic loading upon key insertion, resolving the contradiction between portability and convenience.
Solution Approach 2:
The key memory device serves as an intermediary between the user and the vehicle's base control system. It stores settings externally and automatically transfers them to the vehicle when needed, enabling both portability across vehicles and seamless operation without user intervention.
2Adaptability or versatility
If users manually adjust settings each time they switch vehicles, then settings can be customized for each vehicle, but this process is time-consuming and complex
Solution Approach 1:
The system performs preliminary action by automatically loading stored settings from the key memory device into the vehicle's base control system upon key insertion. This eliminates the need for users to manually adjust settings each time they switch vehicles, saving time while maintaining full customization capabilities.
Solution Approach 2:
The key memory device enables self-service by automatically managing the transfer of settings between vehicles without requiring user intervention. The system autonomously loads the correct settings when the key is inserted, reducing both time and complexity while preserving customization.
3Ease of operation
If advanced vehicle controls are made highly customizable, then user interaction and control are improved, but more disclaimers and user acquiescence are required before settings can change
Solution Approach 1:
The patent creates a copy of the base control system settings and stores it in an external key memory device. This allows advanced customization to be preserved and transferred without requiring users to navigate complex disclaimer interfaces each time, as the customized settings are automatically restored from the key.
Solution Approach 2:
The system performs preliminary customization actions by storing all desired setting changes in the key memory device before vehicle operation. When the key is inserted, these pre-configured settings are automatically applied, eliminating the need for users to repeatedly encounter disclaimer interfaces while maintaining full control capability.

AI summary
A system includes a processor configured to detect a vehicle key and display a key identification on a vehicle display. The processor is also configured to receive a request to export vehicle system and state settings to a key memory. The processor is further configured to access a plurality of predefined settings, designated as key-storable settings, from a vehicle CAN bus, responsive to the request, and transmit the predefined settings to the key, including instructions to store the settings to the key memory.
