Wireless Vehicle Network Authorization via Physical Action Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless vehicle networks lack secure authorization mechanisms, leading to unintentional connections and potential safety hazards when operators attempt to control vehicle functions remotely using mobile devices, as existing methods are cumbersome and inflexible, especially in truck-trailer combinations.
Innovation Solution
A method for secure authorization in wireless vehicle networks involves a mobile communications unit requesting authorization from a vehicle-based communications unit, with the control unit detecting actions performed by the operator and extending access rights only after confirmation, using a combination of wireless and physical-mechanical connections, and potentially encrypted communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless connection is established between mobile device and vehicle communications unit, then remote access to vehicle functions is enabled, but unauthorized or unintentional connections may occur causing safety hazards
Solution Approach 1:
The patent implements preliminary authorization actions before enabling remote control functions. The mobile device must first establish a wireless connection and receive authorization data (such as passwords or security codes) before any vehicle functions can be controlled. This preliminary authentication step prevents unauthorized access while allowing legitimate remote operation.
Solution Approach 2:
The vehicle communications unit acts as an intermediary between the mobile device and the vehicle control systems. It receives authorization requests, validates them against stored authorization data, and only permits controlled functions if validation succeeds. This intermediary layer isolates the mobile device from direct access to critical vehicle systems, enhancing safety.
2Ease of operation
If authorization data is transmitted to mobile device via USB cable, NFC or QR code, then connection setup is simplified, but the process becomes cumbersome and inflexible
Solution Approach 1:
The patent employs multiple transmission media (USB cable, NFC, QR code) as universal interfaces for delivering authorization data. Each method serves the same function of secure data transfer but offers different convenience levels for various scenarios. The system can adaptively select or combine these methods based on the specific situation, making the overall process more flexible and efficient.
3Adaptability or versatility
If multiple operators can access vehicle functions simultaneously, then collaboration is improved, but unintentional or conflicting function activation may occur
Solution Approach 1:
The system implements feedback mechanisms where the communications unit monitors which mobile devices are authorized and what functions they are attempting to control. When multiple operators are connected, the system tracks their authorization levels and can prevent conflicting operations by checking current system state before allowing function activation, thereby avoiding harmful interactions.

AI summary
A method for authorization in a wireless vehicle network is disclosed. In particular, the method is for authorizing communication between a mobile communications unit and a vehicle-based communications unit assigned to a control unit in a vehicle, wherein there is an unauthorized connection between the mobile communications unit and the vehicle-based communications unit. In the method, the mobile unit sends to the vehicle-based unit a request to authorize communication. Thereupon, the vehicle-based unit sends to the mobile unit from which the request came, an instruction to perform an action on the vehicle. An operator who has access to the mobile unit and to the vehicle performs the action. The control unit detects the performed action. The vehicle-based unit authorizes communication with the mobile unit.
