Dynamic Vehicle Access via Portable Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle access systems are inflexible and lack effective means to dynamically grant access to multiple users based on dynamic permissions while maintaining security and convenience, particularly in keyless entry and smart key systems.
Innovation Solution
A system that uses portable devices and key fobs to communicate with vehicles via wireless signals, enabling dynamic authentication and authorization through a network, allowing multiple users to access and control vehicle functions without physical contact, using Bluetooth low energy signals and secure communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional key fob systems are used for vehicle access, then security is maintained through encryption and physical possession requirements, but flexibility and dynamic access management for multiple users are limited
Solution Approach 1:
The patent introduces a server as an intermediary component that manages authentication and authorization for multiple devices. The server receives authentication requests from portable devices, verifies credentials, and coordinates with the vehicle system to grant access. This intermediary architecture enables dynamic access management for multiple users without requiring each device to have full key fob functionality, thus improving versatility while distributing system complexity across the network infrastructure.
Solution Approach 2:
The patent enables portable devices (smartphones, tablets, wearables) to function as virtual key fobs through a universal authentication system. Multiple types of devices can authenticate users and grant vehicle access using the same underlying mechanism (cryptographic verification through the server). This multi-functionality allows diverse devices to serve the same access control purpose, dramatically improving adaptability without proportionally increasing device complexity.
2Ease of operation
If keyless entry systems with multiple authorized devices are implemented, then flexibility and convenience are improved, but security risks and authentication challenges increase
Solution Approach 1:
The patent implements preliminary authentication actions where users must verify their identity through multiple factors (biometric data, device credentials, server verification) before the vehicle access is granted. The system performs preliminary checks including device registration, credential verification, and user authentication through the server before allowing the portable device to function as a key fob. This preliminary action ensures security is established before convenience is provided, maintaining reliability while enabling ease of operation.
Solution Approach 2:
The patent incorporates feedback mechanisms where the server continuously monitors authentication attempts, device status, and access patterns. The system provides feedback to both the vehicle and portable devices about authentication success, authorization status, and security events. This feedback loop allows the system to dynamically adjust security responses, maintain reliable access control, and provide real-time information about the authentication state to improve user convenience.

AI summary
A system for providing dynamic access to a vehicle via a plurality of devices. A device (310, 312) and/or a server (318) of an authentication network (314) stores fob data relating to one or more key fobs (306, 308) linked to the vehicle (302, 304), and device data that includes data relating to one or more devices that are authorized to access the vehicle. The vehicle receives (1402) an access request indicating that a new device is requesting access to the vehicle, whereupon a challenge may be transmitted (1404) to one or more of the authorized devices. The one or more devices may respond, granting access to vehicle functions. The vehicle and/or authentication network (314) generates (1412) a secure fob key and access limitations (1706, 1708) based on the response and transmits the secure fob key to the new device. The new device may be authenticated (1414) to access vehicle functions subject to the limitation based at least in part on the fob key.
