Vehicle Audio System Speed Alert via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle event detection systems, including anti-theft and speed alert systems, often provide ineffective alerts due to generic and easily ignorable notifications, which fail to deter theft or reduce speeding effectively, especially in crowded environments.
Innovation Solution
A system that utilizes a vehicle's data communications bus to integrate a wireless transceiver and controller with the audio entertainment system, allowing for hands-free voice alerts via a mobile device, enabling more effective vehicle speed and status alerts through the vehicle's audio system, including cellular transceivers and a multi-vehicle compatible controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a generic audible alarm indication is used, then the device complexity is reduced, but the effectiveness of the alarm is weakened because it is easily ignored by bystanders
Solution Approach 1:
The patent introduces a mobile communication device as an intermediary between the vehicle alarm system and the user. The system sends alerts to the mobile device, which then relays information to the user, allowing complex alerting strategies without increasing vehicle system complexity
Solution Approach 2:
The system uses the vehicle's existing audio entertainment system for speed alerts, making the audio system serve multiple functions (entertainment and safety alerts). This leverages existing components to provide enhanced alerting without adding dedicated new hardware
2Reliability
If a text display or stand-alone audio output is used for speed alerts, then the device complexity is reduced, but the effectiveness of the alert is weakened because it may not sufficiently cause a reduction in speed
Solution Approach 1:
The patent configures the vehicle audio entertainment system to provide speed alert notifications, making the audio system serve dual purposes of entertainment and safety alerting. This approach leverages existing high-quality audio components to deliver effective speed warnings without adding dedicated alert hardware
3Reliability
If the vehicle audio entertainment system is directly interfaced with a security system, then the alert effectiveness is improved, but the ease of manufacture is reduced due to complicated interfacing and potential warranty issues
Solution Approach 1:
The patent introduces a controller as an intermediary layer between the security system and the audio entertainment system. This controller receives security signals and configures the audio system accordingly, simplifying the integration process and avoiding direct complex interfacing between the security and audio systems
Solution Approach 2:
The system allows the audio entertainment system to be configured through software settings rather than requiring complex physical interfacing. The controller automatically manages the integration, reducing installation complexity and avoiding warranty issues by using manufacturer-approved interfaces

AI summary
A system for a vehicle having a data communications bus extending throughout the vehicle, and an audio entertainment system coupled to the data communications bus may include a vehicle wireless transceiver and a vehicle controller to be coupled to the data communications bus. The vehicle controller may be configured to determine and send a vehicle speed alert via the vehicle wireless transceiver, and selectively set the audio entertainment system to link with the vehicle wireless transceiver in a hands-free mode. The system may also include a mobile device to be carried by a user remote from the vehicle that may include a remote wireless transceiver configured to link wirelessly with the vehicle wireless transceiver. The mobile device may also include a remote controller cooperating to command, based upon receiving the vehicle speed alert, the vehicle controller to set the audio entertainment system into the hands-free mode.
