Dual Authentication Vehicle Remote Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote control systems lack sufficient security measures, particularly for automatically driven vehicles, as they can be compromised if the electronic key is stolen, allowing unauthorized access and operation.
Innovation Solution
A vehicle remote control system that requires successful authentication of both the electronic key and a mobile communication device carried by the user, using near field communication and public communication networks to ensure only authorized users can operate the vehicle-mounted activation unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only electronic key authentication is used, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The authentication system is segmented into two independent components: electronic key authentication and mobile communication device authentication. Both segments must succeed for the activation unit to be operated, dividing the security function into separate verifiable parts that together provide stronger protection than either alone.
Solution Approach 2:
The mobile communication device acts as an intermediary authentication layer between the user and the vehicle's activation unit. It mediates the authorization process by verifying the user's identity through its own authentication mechanism, adding an intermediate security checkpoint that prevents direct access even with a stolen electronic key.
2Reliability
If dual authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The vehicle-mounted authentication unit is designed with multi-functionality to handle both electronic key authentication and mobile communication device authentication through a single integrated system. This universal authentication unit processes different authentication types without requiring separate dedicated hardware systems, reducing overall device complexity despite the enhanced security requirements.

AI summary
A vehicle remote control system including an electronic key pre-registered as a device via which a vehicle can be remote-operated, and a mobile communication device pre-registered as a device that belongs to a user of the vehicle. In the system, a vehicle-mounted authentication unit is configured to determine whether or not authentication of the electronic key and the mobile communication device has succeeded, and a vehicle-mounted allowance determination unit is configured to, if it is determined by the vehicle-mounted authentication unit that the authentication of the electronic key and the mobile communication device has succeeded, allow operation of a predetermined vehicle-mounted activation unit.
