Vehicle Controller Dual-Code Authentication for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems using mobile terminals lack secure authentication mechanisms, allowing unauthorized users to remotely operate vehicles, leading to potential theft and security risks.
Innovation Solution
A vehicle controller system that employs a dual-code authentication mechanism, where a first code is output for starting the engine and a second code is used for door lock control, ensuring that only authorized users can execute these operations by verifying the authenticity of both codes through a judging apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile phone and in-vehicle apparatus are associated for remote operation, then user can operate vehicle functions remotely, but stranger can operate vehicle when in-vehicle apparatus is insidiously installed
Solution Approach 1:
The patent segments the authentication process into two distinct codes: a first code for engine starting authentication and a second code for door lock control authentication. This segmentation ensures that even if one authentication mechanism is compromised, the other remains protected, thereby resolving the security vulnerability while maintaining remote operation capability
Solution Approach 2:
The patent introduces a judging apparatus as an intermediary between the mobile terminal and the vehicle controller. This intermediary verifies the authenticity of codes before executing operations, adding a security layer that prevents unauthorized access while allowing legitimate remote operations to proceed
2Reliability
If authentication mechanism is added to verify code authenticity, then vehicle security is improved, but system complexity increases
Solution Approach 1:
The judging apparatus serves multiple functions: it authenticates the first code for engine starting, authenticates the second code for door lock control, and coordinates communication between the mobile terminal and vehicle controller. By making this single component multi-functional, the patent avoids the need for separate authentication systems for each operation type, thereby limiting the increase in system complexity

AI summary
A vehicle controller is installed in a vehicle and controls one or more operations of the vehicle. The vehicle controller includes a control unit that: (i) outputs a first code for authentication to a judging apparatus which judges whether to permit starting of a driving apparatus of the vehicle when a request for starting the driving apparatus is obtained from an information processor which is located outside the vehicle, (ii) controls locking and unlocking of doors of the vehicle when a request for door lock control is obtained from the information processor, and (iii) obtains from the judging apparatus an authentication result of whether the first code and a second code for authentication which the judging apparatus uses are identical. When obtaining the request for door lock control, the control unit controls the locking and unlocking of the doors based on the authentication result.
