Vehicle Access Control Using Dynamic Security Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle access systems lack flexibility in granting varying levels of access and security, as each key or keyfob has a uniform access level, and there is no method to control or revoke access automatically in case of compromise or loss.
Innovation Solution
Implementing a system that uses various devices and access control methods to grant access based on security profiles, allowing different access levels and enabling authentication through multiple devices, including mobile devices and access cards, with the ability to customize permissions and revoke access if lost or compromised.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional keys or keyfobs are used for vehicle access, then access control is simple and reliable, but access levels are uniform and inflexible
Solution Approach 1:
The patent segments access control into multiple hierarchical levels (e.g., basic access, limited access, full access) that can be assigned to different devices. Each device type (mobile device, access card, keyfob) can be configured with specific access permissions, allowing the system to provide varied access levels without requiring complete system redesign for each scenario.
Solution Approach 2:
The access control system transitions from static, fixed access levels to dynamic, configurable access levels. The system allows real-time modification of access permissions based on user needs, device type, and security requirements. Access levels can be adjusted remotely and changed on-the-fly without physical reconfiguration of the access control hardware.
2Adaptability or versatility
If multiple access devices are permitted for flexibility, then access control versatility improves, but security risk increases when devices are lost or compromised
Solution Approach 1:
The system continuously monitors the status and location of all registered access devices. When a device is reported lost, stolen, or compromised, the system receives immediate feedback and automatically responds by revoking that device's access permissions. The system also provides feedback to users about the security status of their devices and allows remote monitoring of access attempts.
Solution Approach 2:
The system performs preliminary security measures by requiring authentication and authorization checks before granting access. Access devices must be validated against security profiles and permissions before allowing vehicle access. The system proactively manages security by pre-configuring access levels and automatically responding to security events before they can cause harm.
3Ease of operation
If access permissions are fixed in traditional systems, then system simplicity is maintained, but user control and customization capability are limited
Solution Approach 1:
The system enables users to self-manage their own access permissions through intuitive interfaces. Users can register new devices, modify their own access levels, and manage their device profiles without requiring administrative intervention. The system provides self-service capabilities for common tasks while maintaining centralized security management for complex configurations.
Solution Approach 2:
The access control system is designed to work with multiple types of devices (mobile devices, access cards, keyfobs, biometric sensors) through a universal platform. A single system manages diverse device types and authentication methods, providing consistent user control capabilities across different device categories while maintaining a unified management interface.
4Extent of automation
If traditional key systems are used, then device simplicity is maintained, but automatic access revocation capability is absent
Solution Approach 1:
The system implements automatic revocation through continuous feedback loops that monitor device status, user reports, and security events. When loss or compromise is detected through any channel (user report, unauthorized access attempt, device malfunction), the system automatically responds by revoking access permissions without human intervention. This feedback-driven automation maintains security while reducing manual management overhead.
Solution Approach 2:
The system introduces a centralized access control server as an intermediary between access devices and the vehicle. This intermediary manages all authentication, authorization, and revocation operations, allowing automatic response to security events while keeping the vehicle's onboard systems relatively simple. The intermediary handles the complexity of automated revocation logic and device management externally.

AI summary
Embodiments are directed to employing various methods and devices to access a vehicle and controlling a level of access granted based on the device and methods employed. Controlling access to a vehicle can comprise maintaining a plurality of security profiles, each security profile associated with a different access device or type of access device. When the presence of an access device in proximity to the vehicle or a request to access the vehicle is detected, a security profile associated with the detected access device or the request to access the vehicle can be retrieved and used to determine whether to grant access to the vehicle. In response to determining to grant access to the vehicle, access to the vehicle can be provided according to an access level for the detected access device or the request to access the vehicle identified in the retrieved security profile.
