Transit Vehicle Transmission Control via Operator Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unauthorized use of transit vehicles poses a significant challenge for the transportation industry, as existing security systems are inadequate in restricting vehicle operation to trained and trusted operators.
Innovation Solution
A method and system for controlling transit vehicle transmission through operator authentication, utilizing a Vehicle Logic Unit (VLU) that authenticates operators and transmits signals enabling control only upon successful authentication, incorporating secure PIN systems or biometric verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security systems (passwords, mechanical locks) are used to restrict vehicle access, then basic identification is provided, but they are insufficient to prevent unauthorized use and theft
Solution Approach 1:
The patent combines multiple authentication methods (biometric recognition, PIN code verification, and transmission control) into a unified security system. The biometric sensor captures operator characteristics, the processor verifies authentication credentials, and the transmission controller restricts vehicle operation - merging these functions into an integrated system that resolves the contradiction between security effectiveness and system complexity.
Solution Approach 2:
The transmission controller serves as an intermediary component between the authentication system and the vehicle's propulsion system. It acts as a mediator that receives authentication status from the processor and controls transmission engagement accordingly, providing an additional layer of security without requiring direct modification of the engine or ignition system.
2Reliability
If transmission control is implemented through authentication, then unauthorized operation is prevented, but the system requires additional components and processing steps
Solution Approach 1:
The processor in the system performs multiple functions: it processes biometric data from the sensor, verifies PIN codes, controls the transmission controller, and manages ignition sequences. By making the processor multi-functional, the system achieves reliable authentication without adding separate dedicated hardware for each function, thus reducing overall system complexity.
Solution Approach 2:
The system uses the operator's own biometric characteristics (fingerprint, facial recognition, or iris pattern) as the authentication key, eliminating the need for physical keys, cards, or tokens. This self-service approach enhances reliability while simplifying the system by removing the need for managing and distributing physical authentication media.
3Reliability
If biometric authentication is required for vehicle operation, then security against theft is enhanced, but the authentication process takes additional time
Solution Approach 1:
The system performs preliminary authentication checks by capturing and verifying biometric data before allowing transmission engagement. The processor pre-validators authentication credentials and only then permits the transmission controller to disengage restrictions, ensuring security is established before vehicle operation begins, which minimizes authentication time during actual vehicle use.
Data Source
AI summary
Methods and apparatus are provided for controlling a transmission of a transit vehicle. A Vehicle Logic Unit (VLU) authenticates an operator of the transit vehicle, upon start-up of the transit vehicle and the VLU. The VLU transmits a signal enabling operator control of the transmission of the transit vehicle, when the operator of the vehicle is authenticated.
