Vehicle Accessory Module Remote Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rental vehicle sharing operations face inefficiencies due to the need for users to physically visit rental sites for key collection and lack of remote vehicle tracking, disabling, and diagnostic monitoring capabilities.
Innovation Solution
A system utilizing a mobile computing device and an accessory module with a CNG module, including a network access device, GPS module, cybersecurity gateway module, and cryptographic module, enables remote authorization and control of vehicle access and operations through short-range wireless communication protocols, allowing users to access and manage rental vehicles without physical keys or key fobs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users physically visit rental sites to collect keys and obtain vehicle access, then vehicle access authorization can be confirmed, but user time and operational efficiency are reduced
Solution Approach 1:
The patent replaces the mechanical key collection process with an electronic authentication system. The authentication module communicates with the rental company's server via wireless network to verify user credentials and grant vehicle access electronically, eliminating the need for physical key collection and reducing site visit requirements
Solution Approach 2:
The patent introduces an authentication module as an intermediary between the user and the vehicle. This module handles the authentication process by communicating with both the user's mobile device and the rental company's server, enabling remote authorization and eliminating the need for direct physical interaction at the rental site
2Reliability
If vehicles are secured at centralized facilities until key collection, then vehicle security is maintained, but remote tracking and monitoring capabilities are lost
Solution Approach 1:
The authentication module serves multiple functions: it authenticates users for vehicle access, tracks vehicle location via GPS, monitors vehicle diagnostics, and enables remote disabling. This multi-functional approach maintains security while providing comprehensive remote monitoring capabilities that prevent information loss about vehicle status and location
3Ease of operation
If physical keys or key fobs are used for vehicle access, then simple access control is achieved, but remote authorization and control capabilities are limited
Solution Approach 1:
The patent replaces physical keys and key fobs with an electronic authentication system that uses wireless communication. The authentication module communicates with the rental company's server to verify credentials and grant access, enabling remote authorization without requiring physical key distribution
Solution Approach 2:
The authentication module acts as an intermediary that enables remote authorization by communicating between the user's mobile device and the vehicle's control systems. This allows the rental company to authorize access remotely and provides adaptability for various authorization scenarios without being limited to physical key distribution
