Active Vehicle Seat Security via Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seats lack effective security measures to prevent unauthorized operation and theft, particularly in scenarios where electrical, mechanical, pneumatic, or hydraulic connections are compromised.
Innovation Solution
An active vehicle seat system that includes an electromagnetic actuator for suspension and a controller to detect security threats, disabling operation by setting the seat to an inoperable position unless authenticated by an authorized user through password, biometric data, or security card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bolt fastening is used to install vehicle seats, then installation simplicity is maintained, but security against theft and unauthorized operation is insufficient
Solution Approach 1:
The patent combines the vehicle seat with multiple security functions including electromagnetic actuators for active suspension, authentication devices (biometric sensors, card readers, keypads), and controllers that monitor for security threats. This merging transforms a simple seating component into an integrated security system that prevents theft and unauthorized operation while maintaining seat functionality.
Solution Approach 2:
The vehicle seat is designed to perform multiple functions beyond basic seating: it provides active suspension through electromagnetic actuators, authentication through various devices (fingerprint, card, keypad), security monitoring for severed connections, and the ability to render the vehicle inoperable. This multi-functionality addresses the security improvement need while consolidating multiple security features into a single seat unit.
2Reliability
If the seat is disabled in response to security threats, then security is improved, but operational availability decreases
Solution Approach 1:
The controller continuously monitors the vehicle seat system for security threats such as severed electrical, mechanical, pneumatic, or hydraulic connections. When a threat is detected, the system provides feedback by disabling the seat operation and rendering the vehicle inoperable. The system maintains this disabled state until authentication is provided, at which point normal operation is restored. This feedback mechanism ensures security while allowing operational availability when authorized.
Solution Approach 2:
The system takes preliminary action by disabling the seat and rendering the vehicle inoperable before any unauthorized operation can occur. The authentication requirement is established in advance, preventing unauthorized use while allowing legitimate users to operate the vehicle normally after authentication. This preliminary security measure balances protection with operational availability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively renders the vehicle inoperable when unattended or under threat, requiring authentication to restore functionality, thereby enhancing security and preventing theft.

AI summary
A method for operating an active vehicle seat in a vehicle includes detecting a triggering event related to a security threat to the active vehicle seat. An operation of the active vehicle seat is disabled in response to the detected triggering event. The operation of the active vehicle seat is enabled by providing authentication of an authorized user.
