Vehicle Access Control System for Secure Service Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle access systems require driver presence for maintenance and services, which is inconvenient and time-consuming, especially when maintenance involves simple tasks like refueling, cleaning, or tire changes.
Innovation Solution
A system that allows service personnel to access and perform services on a vehicle without the owner's direct participation, using a communication network to authenticate and authorize access through a unique, time-limited code, ensuring secure and efficient maintenance operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyless entry access units are used for vehicle access, then ease of operation is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent implements dynamic access control where the vehicle access control unit transitions between different operational states based on detected signals. The system dynamically adjusts authorization levels - normal keyless entry operation versus service mode access - based on real-time communication with external units, creating a adaptive security system that responds to different operational contexts
Solution Approach 2:
The patent introduces an intermediary service mode that acts as a controlled bridge between external service personnel and the vehicle's access control system. This intermediary layer verifies service authorization through external units before granting limited access, preventing direct bypass of security measures while still enabling necessary maintenance operations
2Reliability
If driver presence is required for maintenance services, then security is improved, but productivity deteriorates
Solution Approach 1:
The patent enables the vehicle access control system to autonomously manage service access by detecting and verifying external service units. The system automatically transitions to service mode, grants appropriate access rights, and manages the service process without requiring continuous driver intervention, while maintaining security through automated authorization verification
Solution Approach 2:
The patent implements preliminary service authorization where service personnel must be pre-registered and authorized through the system before accessing the vehicle. The access control unit stores and verifies service authorizations in advance, allowing rapid authentication during service operations without requiring driver presence for verification
3Reliability
If time-limited access codes are implemented for service personnel, then security is improved, but device complexity increases
Solution Approach 1:
The patent makes the existing vehicle access control unit multi-functional by enabling it to handle both traditional keyless entry operations and service mode access control. The same control unit processes different types of access requests (driver keys, service personnel, remote access) using unified communication protocols, avoiding the need for separate dedicated service access hardware
Data Source
AI summary
System for selectively opening a vehicle, comprising a first communication module for establishing a communication link to a communication terminal of a service provider who obtains authorization data via a communication network, a first identification routine for unambiguously identifying the service provider, a second communication module for establishing, via a wireless communication network, a communication link to a communication device of a control unit of the access arrangement on a vehicle, a second identification routine allowing the access arrangement to unambiguously identify the system, a third communication module for receiving update request data from the driver, and an update routine for updating authorization data in a memory of the system. When valid authorization data has been provided, the control unit, using the second communication module for establishing, via a wireless communication network, a communication link to a communication device of the control units of the access arrangement off a vehicle, receives a profiled control signal via the communication link, said profiled control signal causing the vehicle to be selectively opened via the control unit.
