Connected Helmet Access Control for User-Specific Vehicle Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing off-road vehicles lack a reliable method to adjust and store user-specific settings, particularly for multiple users, and do not have a way to restrict certain functions, especially for child operators.
Innovation Solution
A helmet system that communicates vehicle function settings to the vehicle's controller, allowing users to store and adjust settings directly from the helmet, and enabling parental controls by restricting certain vehicle functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle settings are adjusted through menu displays at the vehicle, then settings can be changed, but multiple users cannot maintain their own favorite settings simultaneously
Solution Approach 1:
The patent uses RFID tags to create portable copies of user settings that can be stored in helmets or key fobs. When a user approaches the vehicle with their tagged helmet, the settings are automatically copied from the tag to the vehicle's memory, allowing each user to have their own personalized settings without complex manual reconfiguration.
Solution Approach 2:
The RFID tag serves as an intermediary carrier that stores user settings and enables automatic transfer to the vehicle. This mediator simplifies the settings management system by providing a portable storage medium that bridges the gap between users and the vehicle's control system.
2Object-affected harmful factors
If no known way to restrict vehicle functions is available, then all functions remain accessible, but children cannot be restricted from operating certain functions
Solution Approach 1:
The patent applies different access rights to different vehicle functions based on the user's RFID tag. Children's tags are programmed with restricted access permissions that allow only certain basic functions, while adult tags have full access. This local quality approach restricts specific functions for specific users without requiring a complex centralized control system.
Solution Approach 2:
User-specific permission sets are copied from RFID tags to the vehicle's memory, enabling automatic authentication and function restriction. When a child's helmet with a restricted tag approaches the vehicle, the system copies the limited permission set and automatically disables certain functions, providing safety without complex manual intervention.
3Adaptability or versatility
If settings are stored only in the vehicle, then settings are available, but users cannot easily transfer or share settings between different vehicles or locations
Solution Approach 1:
The patent segments the settings storage system into two parts: a portable RFID tag that stores user preferences and permissions, and a vehicle memory that stores settings for the current session. This segmentation allows settings to be easily transferred between vehicles while maintaining reliability through the persistent storage on the RFID tag.
Solution Approach 2:
Settings are copied from the portable RFID tag to the vehicle's memory when a user approaches, and can be copied back to the tag when changes are made. This copying mechanism ensures settings are reliably stored in both locations, providing portability across different vehicles while maintaining data integrity.
Data Source
AI summary
A programming device includes an application for programming vehicle function settings of a vehicle. The programming device has a transmitter that communicates the vehicle function settings through a vehicle receiver to a vehicle controller. The vehicle function settings cause the controller to operate the vehicle when a device identifier is received from a moveable device associated with a vehicle user.
