Targeted Vehicle Message Broadcasting via Filter Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information broadcasting systems cannot target specific vehicles or vehicle owners with messages, such as maintenance reminders and recall notices, and lack the ability to selectively replay or correct broadcasted messages.
Innovation Solution
A system and method for broadcasting targeted messages to specific vehicles using a filter code section and unique identifiers, allowing for selective message storage and deletion, enabling targeted communication and remote editing of messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If broadcast messages are sent to all members of the public using radio signals, then the coverage area is maximized, but the messages cannot be targeted to specific vehicle owners or specific makes/models of vehicles
Solution Approach 1:
The broadcast message is segmented into multiple components: a common header containing filter codes that apply to all receivers, and individual message portions tailored to specific vehicle characteristics. Each message portion is associated with specific filter codes (e.g., vehicle make, model, year) that enable selective reception by targeted vehicles while maintaining broad broadcast coverage.
2Speed
If audio and visual broadcast information is presented continuously to the vehicle operator, then the information is delivered in real-time, but the operator cannot capture the information for later presentation
Solution Approach 1:
The system performs preliminary action by storing the broadcast message portions in a mailbox memory before they are presented to the operator. This allows the information to be delivered in real-time while also being captured and stored for later playback when the vehicle is not in motion and it is convenient to review the message.
3Device complexity
If broadcast messages are sent to all vehicles, then the system simplicity is maintained, but irrelevant information causes irritation to vehicle operators
Solution Approach 1:
The system applies local quality by incorporating filter codes within the broadcast message structure that enable each vehicle receiver to selectively process only the message portions relevant to its specific characteristics (make, model, year). This filtering mechanism eliminates irrelevant information from being presented to the operator, reducing irritation while maintaining system simplicity.
4Reliability
If corrected messages are rebroadcast to vehicle operators, then the error correction is achieved, but the proliferation of messages represents an irritation to the operator
Solution Approach 1:
The system implements feedback by providing operators with the ability to selectively delete individual messages from the mailbox memory. When a message contains erroneous or stale information, the operator can identify and delete that specific message using its unique identifier, preventing the accumulation of multiple redundant messages and eliminating the irritation caused by message proliferation.
Data Source
AI summary
The invention provides systems and methods for targeting broadcast messages to particular vehicles or classes of vehicles. In one embodiment, the system comprises an information center for creating and sending a broadcast data message, and a relay section that receives the broadcast data message and relays the message to a plurality of vehicles. The information center typically comprises a one-to-many communication system for sending the message from one source to a plurality of receivers, such as a satellite radio network or the like. The message can be deleted or modified in response to commands received by the receiver.
