Key Fob Base Station for Nomadic Device Vehicle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic key systems lack efficient methods for secure and convenient vehicle access management, particularly in scenarios where traditional key fobs are not readily available, and there is a need for enhanced user control and authorization mechanisms.
Innovation Solution
A vehicle key base station system that communicates with a key fob and nomadic devices via transceivers, allowing secure transmission of vehicle security codes and enabling key fob functions, with features like remedial actions and user authorization, using a computer-implemented product with instructions for processor execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional key fob systems are used for vehicle access, then vehicle security is maintained through established protocols, but user convenience is reduced when key fobs are not readily available
Solution Approach 1:
The base station acts as an intermediary device between the key fob and nomadic devices. It receives security codes from the key fob via short-range wireless communication and redistributes them to authorized nomadic devices via network communication, enabling access without direct key fob-nomadic device pairing
Solution Approach 2:
The system creates a digital copy of the key fob's security code and redistributes it to multiple authorized nomadic devices. The base station captures the security code from the key fob and generates accessible copies for registered devices, eliminating the need for physical key fob possession
2Adaptability or versatility
If security codes are transmitted to multiple devices, then user accessibility is improved, but security risks increase from potential unauthorized access
Solution Approach 1:
The base station performs preliminary authorization checks before transmitting security codes to nomadic devices. Devices must be pre-registered and authenticated with the base station, establishing trust relationships in advance before any security code distribution occurs
Solution Approach 2:
The system implements feedback mechanisms where the base station continuously monitors communication between nomadic devices and the vehicle. Unauthorized access attempts are detected and reported back to the system, enabling real-time security responses and device authorization revocation if needed

AI summary
A vehicle key base station is configured to comprise at least one controller in communication with a key fob and a nomadic device using one or more transceivers. The at least one controller may be configured to receive a security code request from the nomadic device. The at least one controller may be further configured to verify the nomadic device is approved to communicate with vehicle key fob based on a pre-registration configuration. If the nomadic device is approved, the at least one controller may be further configured to transmit the request to the key fob and receive the vehicle security code from the key fob. The at least one controller may be further configured to transmit the vehicle security code to the nomadic device.
