Vehicle Infrastructure Access Control With Unified Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems for motor vehicle infrastructures, such as parking garages, are often incompatible with one another, leading to the accumulation of multiple cards, units, or computer programs on vehicles that can only control one infrastructure at a time, making it impractical to use multiple infrastructures and complicating administration tasks.
Innovation Solution
A control system that enables a motor vehicle with a first control apparatus to establish a wireless connection with an infrastructure's second control apparatus, allowing for bilateral authentication and enabling the vehicle to request and control predefined functions of the infrastructure, such as access or charging, using a unified authorization system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate access control systems are used for different infrastructures, then each infrastructure can be controlled independently, but the device complexity and number of authentication tokens accumulate
Solution Approach 1:
The patent implements a universal access control system where a single authentication token (mobile device) can authenticate with multiple different infrastructure types (parking garages, charging stations, washing stations). The system uses a centralized server that manages authorization for various infrastructure providers, allowing one token to serve multiple functions across different infrastructures rather than requiring separate tokens for each.
Solution Approach 2:
The patent combines multiple separate access control systems into a unified system. Instead of having independent authentication systems for each infrastructure, the invention merges them into a single ecosystem where a central server coordinates authentication between the mobile device and multiple infrastructure providers, reducing the number of separate control units needed in the vehicle.
2Adaptability or versatility
If multiple infrastructure-specific authentication tokens are carried, then access to each infrastructure is possible, but the ease of operation deteriorates due to selection complexity
Solution Approach 1:
The system enables automatic infrastructure selection and authentication. When the vehicle approaches an infrastructure, the system automatically detects the infrastructure type, selects the appropriate authentication method, and completes the authentication process without requiring the user to manually choose from multiple tokens or cards. The mobile device and control system work together to handle the authentication automatically.
Solution Approach 2:
The system performs preliminary authentication setup by storing authorization data for multiple infrastructures in advance within the mobile device and control system. This allows the system to quickly retrieve and use the appropriate credentials when approaching different infrastructures, eliminating the need for real-time selection of authentication tokens.
3Adaptability or versatility
If separate control systems are used for each infrastructure, then infrastructure-specific control is possible, but the administration complexity increases
Solution Approach 1:
The patent introduces a central server as an intermediary between the mobile device and multiple infrastructure providers. This server manages authorization data, handles authentication requests, and coordinates control actions across different infrastructures. By placing the administrative complexity in the central server rather than in each individual infrastructure system or in the vehicle, the invention simplifies the overall administration while maintaining infrastructure-specific control capabilities.

AI summary
A control system includes a motor vehicle with a first control apparatus and an infrastructure with a second control apparatus. The control apparatuses are configured to establish a wireless connection to one another and to carry out a bilateral authentication via the connection. The motor vehicle is configured to request a predefined function of the infrastructure via the connection; and the second control apparatus is configured to perform the requested function of the infrastructure if the function is enabled for control by way of the motor vehicle.
