Mobile Device Vehicle Control via Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle ignition and entry systems, reliant on fobs, are inconvenient due to the need to carry and potentially lose additional devices, and alternatives like phone-as-a-key solutions face implementation difficulties.
Innovation Solution
A system that uses a processor to wirelessly communicate with a mobile device application, allowing vehicle control through a fob-device that can be programmed to interact with multiple vehicles, using a phone or mobile device to select and control vehicle functions, and send instructions to the fob-device for vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fob device is used for vehicle control, then vehicle access and control functions are provided, but the user must carry and potentially lose an additional device
Solution Approach 1:
The patent combines the fob device functionality with a mobile device that the user already carries. The system integrates vehicle control capabilities into the mobile device through wireless communication, eliminating the need to carry a separate fob while maintaining all vehicle access and control functions.
Solution Approach 2:
The mobile device serves multiple functions: it acts as both a communication device for the user and a vehicle control interface. The system allows the mobile device to perform various vehicle functions including locking, unlocking, starting, and stopping the vehicle, making it a universal control device.
2Ease of operation
If phone-as-a-key functionality is implemented, then fob carrying is eliminated, but implementation difficulties arise due to technical challenges
Solution Approach 1:
The patent introduces a server as an intermediary between the mobile device and the vehicle. The server facilitates secure communication and authentication, handling the complex cryptographic operations and vehicle control logic remotely, thereby reducing the implementation burden on the mobile device while enabling phone-as-a-key functionality.
3Adaptability or versatility
If multiple vehicle control credentials are stored on fob-device, then control of multiple vehicles is enabled, but security risks increase if compromised
Solution Approach 1:
The patent segments the credential storage and processing across multiple components: the mobile device stores credential information, the server manages authentication and security protocols, and the vehicle receives controlled access commands. This distribution of functions enhances security by preventing a single point of compromise while maintaining multi-vehicle control capability.

AI summary
A system includes a processor configured to wirelessly communicate with a mobile device application. The processor is further configured to receive a vehicle-command from the mobile device application and send a wireless instruction to a vehicle instructing an action corresponding to and responsive to the received vehicle command.
