Vehicle Access Control Using Proximity and NFC Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle function limiting systems cannot dynamically enable or disable specific vehicle functions as needed, leading to inconveniences such as a locked trunk during valet parking.
Innovation Solution
A vehicle control system utilizing a portable device and in-vehicle controller that determines the proximity of the device to the vehicle and establishes near-field communication with an authorized user's terminal to permit specific operations, allowing functions to be enabled or disabled based on user authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle functions are limited when using a portable device, then security is improved, but flexibility and convenience deteriorate as functions cannot be made available as needed
Solution Approach 1:
The system dynamically changes the availability of vehicle functions based on the proximity of the portable device to the vehicle. When the device is within a predetermined range, near field communication is established and functions become available; when outside the range, functions are limited. This dynamic adaptation resolves the contradiction between security and flexibility.
Solution Approach 2:
The portable device acts as an intermediary that mediates between the user and the vehicle system. Through near field communication between the portable device and the in-vehicle controller, the system determines whether to grant access to specific functions, providing both security verification and convenient access when needed.
2Reliability
If near field communication verification is implemented, then unauthorized access is prevented, but system complexity increases
Solution Approach 1:
The system uses self-service authentication through near field communication between the portable device and the in-vehicle controller. The portable device automatically performs verification when brought near the vehicle, eliminating the need for manual authentication processes while maintaining security. This reduces operational complexity despite adding verification functionality.

AI summary
A vehicle control system includes a portable device configured to store information on an electronic lock of a vehicle and an in-vehicle controller configured to communicate with the portable device, the in-vehicle controller being installed in the vehicle. The in-vehicle controller is configured to generate a permission command to permit the specific operation to be performed when the in-vehicle controller determines that the operation requested to be performed on the vehicle is a specific operation that needs permission from the authorized user, in-vehicle controller when the in-vehicle controller determines that the portable device is within a predetermined range around the vehicle, and when the in-vehicle controller determines that near field communication between the portable device and the communication terminal based on a first telecommunications standard is established.
