Dynamic Electronic Key Deactivation for Valet Parking Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous valet parking systems, there is a need to prevent unauthorized access to vehicles using electronic keys, as existing methods do not effectively ensure that deactivated keys cannot be used to access vehicle components while the vehicle is parked.
Innovation Solution
A method and system for controlling access to vehicles, where an electronic key is deactivated after the vehicle is switched off for parking, using a key management server and communication network to prevent access to vehicle components, and can be reactivated when necessary, with additional keys generated or sent via the network for access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic key remains activated during parking, then access to vehicle components is maintained for legitimate operations, but unauthorized access and security risks increase
Solution Approach 1:
The electronic key's access rights are made dynamic rather than static. The key management server dynamically adjusts the key's activation status based on the vehicle's operational state. When the vehicle is parked, the key is automatically deactivated; when the vehicle is in operation, the key is reactivated. This dynamic approach resolves the contradiction by adapting security levels to actual operational needs.
Solution Approach 2:
A feedback mechanism is implemented where the vehicle's operational status continuously communicates with the key management server. The server receives feedback about whether the vehicle is parked or in operation and automatically adjusts the electronic key's activation state accordingly. This closed-loop feedback system maintains security while preserving operational flexibility.
2Reliability
If the electronic key is deactivated after vehicle shutdown, then unauthorized access during parking is prevented, but legitimate access for authorized operations may be blocked
Solution Approach 1:
The system performs preliminary deactivation of the electronic key before authorized personnel need access during parking. The key is deactivated automatically when the vehicle enters parking mode, and reactivated in advance when the vehicle transitions to operation mode or when authorized access is requested. This preliminary action ensures security is maintained while allowing legitimate access when needed.
Solution Approach 2:
The key management server acts as an intermediary between the electronic key and the vehicle's access control system. Rather than directly blocking or allowing access, the server mediates by controlling the key's activation status based on vehicle state and authorization requests. This intermediary approach maintains both security and flexibility.
3Ease of operation
If multiple electronic keys are generated for parking operations, then access availability is improved, but system complexity and key management burden increase
Solution Approach 1:
The key management server provides universal control for all electronic keys in the system. Rather than requiring separate management mechanisms for each key, the server centrally manages activation and deactivation of multiple keys based on a single criterion: the vehicle's operational state. This multi-functional approach simplifies key management while ensuring availability.
Solution Approach 2:
The electronic keys are automatically managed through self-service mechanisms. The key management server automatically activates and deactivates keys based on vehicle status without requiring manual intervention for each key. This automated self-service approach reduces management complexity while maintaining key availability.

AI summary
A method for controlling access to a vehicle. An electronic key for accessing one or multiple vehicle components is deactivated after the vehicle is switched off in order to park the vehicle in a parking position, so that an attempt with the aid of the deactivated electronic key to access the one or multiple vehicle components of the vehicle parked in the parking position may be prevented. Moreover, a system for controlling access to a vehicle, a parking system for vehicles, an access control system for controlling access to a vehicle, a vehicle, a user for a communication network, a method for operating a user for a communication network, and a computer program, are described.
