In-Vehicle Intelligent Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control systems for vehicles at access points, such as security gates, remain semi-automated as they require manual intervention from drivers to insert identification cards, limiting full automation despite advancements in autonomous driving systems.
Innovation Solution
An in-vehicle intelligent access control system that stores data identifying the vehicle, its occupants, and itinerary before approaching an access point, using sensors to automatically match and control access, allowing full automation of the access process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection of identification cards is performed by security guards, then access control reliability is improved through subjective matching verification, but productivity deteriorates due to manual intervention requirements
Solution Approach 1:
The patent replaces the mechanical manual inspection process with an automated optical recognition system. Sensors capture images of identification cards and vehicle license plates, and a processor automatically extracts and verifies data, eliminating the need for manual card inspection while maintaining verification reliability
Solution Approach 2:
The system enables self-service access control where the automated recognition system independently performs identification and verification without requiring security guard intervention. The system automatically compares captured data with database records and controls gate operation, making the process self-sufficient
2Productivity
If card readers and RFID devices are used for automated access, then productivity is improved through automated card reading, but ease of operation deteriorates as drivers must manually insert or swipe cards
Solution Approach 1:
The patent replaces manual card insertion or swiping with contactless optical recognition. Sensors automatically capture images of identification cards and vehicle license plates without requiring physical contact, eliminating the manual manipulation step while maintaining automated verification
Solution Approach 2:
The system creates optical copies (images) of identification cards and license plates using sensors, then processes these copies to extract data. This eliminates the need for physical card handling while maintaining the ability to verify identity information
3Reliability
If multiple data points are collected and verified (non-human objects, vehicle ID, human occupants, itinerary), then access control reliability is improved through comprehensive verification, but device complexity increases due to multiple sensors and data processing requirements
Solution Approach 1:
The patent employs a multi-functional sensor system where a single sensor array performs multiple functions: capturing identification card images, vehicle license plate images, and analyzing vehicle characteristics. The processor integrates multiple verification tasks (data extraction, comparison, validation) into a unified process, reducing overall system complexity
Data Source
AI summary
An in-vehicle intelligent access control system and method are configured to automate access of a vehicle to an access point. Prior to approach of the vehicle to the access point, an enrollment system stores, in a database, first data identifying a non-human object in a vehicle, second data identifying the vehicle, third data identifying a human occupant of the vehicle, and fourth data identifying an itinerary of the vehicle. An access control management system receives at least the first data from the database. When the vehicle approaches the access point, the system detects the vehicle within a predetermined range of an access point, receives fifth data transmitted by the vehicle, determines a match of the fifth data with at least the first data within a prescribed tolerance, and controls the access point to allow access of the vehicle to a facility if the fifth data matches at least the first data.
