Vehicle Telematics Unit Mobile Control via Short-Range Wireless
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of older vehicle telematics systems lack the ability to change network name and password settings without interacting with a call center advisor, and there is a need for a method to control vehicle telematics units using mobile devices to manage these settings efficiently.
Innovation Solution
A method and system that allows a mobile device to control a vehicle telematics unit by generating commands to broadcast vehicle data via short-range wireless communication, enabling users to change the network name and password settings without call center intervention, by pairing the mobile device with the telematics unit and transmitting commands to update the credential data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users of older vehicle telematics systems want to change network name and password settings, then they must interact with a call center advisor, but this increases the complexity of operation and reduces user convenience
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the vehicle telematics unit. The mobile device communicates with the telematics unit via SRWC to transmit commands for changing network settings, eliminating the need for call center interaction while maintaining secure controlled access to the system
2Extent of automation
If users want to control vehicle telematics units using mobile devices, then user autonomy increases, but the system must support additional communication protocols and control mechanisms
Solution Approach 1:
The patent enables the system to serve itself by allowing the telematics unit to receive and execute control commands directly from the mobile device without requiring external call center assistance. The unit autonomously processes commands to change network settings, broadcasting credentials and applying configuration changes based on mobile device input
3Reliability
If the telematics unit broadcasts credential data via SRWC, then users can securely connect to the Wi-Fi network, but the network security requirements increase
Solution Approach 1:
The mobile device serves as a secure intermediary that mediates between the user and the telematics unit. It receives credential data from the telematics unit via SRWC, allows secure configuration changes, and maintains controlled access to the network settings, reducing security risks while enabling reliable Wi-Fi connectivity

AI summary
A method and a system for providing control of a vehicle telematics unit using a mobile device. The method carried out by the system includes the steps of: determining a mobile device is configured to control a vehicle telematics unit; receiving at a call center a vehicle telematics unit (VTU) command from the mobile device instructing the telematics unit to provide vehicle data using short range wireless communication (SRWC); sending the VTU command from the call center to the telematics unit; and transmitting via SRWC the vehicle data.
