Off-Board Vehicle Access Control for Remote Lock Authority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle security systems are inadequate in preventing unauthorized access and operation, as they can be bypassed by individuals attempting to board or control vehicles, posing risks to safety and security.
Innovation Solution
A remote access control system that allows an off-board control system to change the vehicle's access state between locked and unlocked states, prohibiting operators onboard from changing the state from locked to unlocked without assistance, thereby enhancing security measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing vehicle security systems are used, then basic access control is provided, but they can be bypassed by individuals attempting to board or control vehicles
Solution Approach 1:
The patent introduces an off-board control system as an intermediary that communicates with the vehicle's onboard system. This external controller receives signals from authorized sources and sends commands to change the vehicle's access state, creating an additional layer of security that cannot be bypassed by simply interacting with the vehicle's own systems.
Solution Approach 2:
The patent moves the control authority from a single-dimension onboard system to a multi-dimensional architecture that includes both onboard and off-board control elements. By adding the spatial dimension of remote control, the system prevents bypass attempts that would otherwise work against traditional onboard-only security systems.
2Reliability
If remote control is implemented to prevent unauthorized access, then security is improved, but the operator onboard is prohibited from changing access state without assistance
Solution Approach 1:
The patent implements dynamic control where the operator's ability to change access state depends on the current state and system conditions. The operator can independently lock the vehicle but requires off-board assistance to unlock, creating a dynamic permission structure that adapts to security needs while maintaining operational flexibility.
Solution Approach 2:
The system changes the control parameters based on the access state. In the locked state, the operator's control authority is restricted for unlocking operations. In the unlocked state, the operator regains full control. This parameter-based control approach balances security requirements with operational ease.
Data Source
AI summary
A control system and a related method includes determining an access state of a vehicle and communicating a locking command message from an off-board control system to remotely change the access state of the vehicle between a locked state and an unlocked state. In the locked state, an operator is unable to one or more of access a location of the vehicle, access an area internal to the vehicle, change a power setting of a component of the vehicle, or engage a propulsion system of the vehicle. The operator onboard the vehicle may be prohibited from changing the access state from the locked state to the unlocked state without assistance from the off-board control system, but the operator may be allowed to change the access state from the unlocked state to the locked state without assistance from the off-board control system.
