Vehicle Access Authorization via Rolling Code and Pre-stored Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing vehicle parking times do not allow delivery services to access vehicles without owner participation, making it difficult to perform services like maintenance, cleaning, or deliveries efficiently.
Innovation Solution
A system that uses a navigation device integrated into a driver assistance system to establish communication links via wireless networks, allowing service providers to access vehicles securely using a rolling code method, enabling remote authorization and service execution without direct owner involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle owner directly participates in every service operation, then service security and authorization are ensured, but service efficiency and productivity decrease due to required owner involvement
Solution Approach 1:
The system pre-generates time-limited authorization codes that are stored in the vehicle's memory before the service operation occurs. This preliminary action allows service providers to access vehicles without real-time owner involvement, improving efficiency while maintaining security through pre-established authorization mechanisms.
Solution Approach 2:
The patent introduces an intermediary authorization code system that mediates between the vehicle owner and service provider. The code acts as a temporary credential that grants access without requiring the owner's physical presence, resolving the contradiction between security (owner authorization) and efficiency (no owner involvement).
2Measurement precision
If multiple service providers manually coordinate deliveries and services, then service accuracy is maintained, but time consumption and logistical complexity increase
Solution Approach 1:
The system enables service providers to autonomously access vehicle information and perform services using pre-stored authorization codes and onboard sensors. The vehicle's own systems (sensors, memory, communication modules) provide service data and execute service routines without manual coordination, reducing time loss while maintaining accuracy through automated processes.
Solution Approach 2:
The patent replaces manual coordination mechanisms with automated electronic systems. Communication modules transmit service data automatically, sensors detect vehicle states without human intervention, and control units execute service routines programmatically, substituting mechanical coordination with automated electronic processes that reduce time consumption.
Data Source
AI summary
A system for selective opening of a vehicle includes: a first communications module establishing, via a communications network, a communication link to a service provider of authorization data; a first identification routine for unambiguous identification of the service provider; a second communications module establishing a wireless communication network link to a control device for access arrangement of a vehicle; a second identification routine unambiguously identifying the system by the access arrangement; and a third communications module receiving update request information from the driver and an authorization data update routine. By the second communications module, the control device receives a profiled control signal that causes a selective opening of the vehicle via the control device if valid authorization data is available.
