Crowdsourced Driver Feedback via Vehicle Identifier Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a convenient and reliable mechanism for humans to provide feedback to human drivers, especially during the transition period from human-driven to fully autonomous vehicles, where vehicle-supported wireless communications technologies are being integrated.
Innovation Solution
A method and system for crowdsourced driver feedback that allows users to provide feedback messages to drivers through a wireless communication link, identifying vehicles using various criteria and transmitting feedback messages based on user inputs, with recipient devices filtering and acting on relevant messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless feedback messages are broadcast to all vehicles in vicinity, then driver behavior improvement is enabled, but communication bandwidth consumption increases
Solution Approach 1:
The patent applies local quality by filtering feedback messages based on vehicle identifiers. Instead of uniformly processing all broadcast messages, each vehicle selectively processes only those messages relevant to its identifier, reducing unnecessary communication processing and bandwidth consumption while maintaining feedback reliability for targeted vehicles.
Solution Approach 2:
The system implements partial action by having recipient devices filter and process only a subset of received feedback messages—specifically those matching their vehicle identifiers. This partial processing approach reduces overall system bandwidth consumption while ensuring that each vehicle receives complete feedback information relevant to it.
2Productivity
If feedback filtering is implemented at recipient devices, then relevant feedback processing is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by embedding vehicle identifiers in feedback messages before transmission. This pre-preparation of identification information allows recipient devices to perform simple matching operations rather than complex analysis, improving feedback processing efficiency while minimizing the complexity burden on recipient devices.
3Ease of operation
If simple feedback messages are used, then ease of operation is improved, but information completeness deteriorates
Solution Approach 1:
The patent applies universality by designing a feedback message structure that serves multiple functions: it can convey simple evaluative feedback (thumbs up/down) while also carrying detailed behavior descriptions and vehicle identifiers. This multi-functional message format enables both ease of operation for simple feedback and information completeness for detailed analysis, depending on what the sender chooses to include.

AI summary
Methods, systems, and devices for wireless communications are described. A human user, such as a pedestrian, cyclist, or driver, may provide a feedback message to a vehicle whose behavior they observe. The feedback message and the recipient may be manually identified by the human user or may be suggested by the system or device. The feedback message may be broadcast and filtered by vehicles within the broadcast radius based on a vehicle identifier. A vehicle that receives the feedback message may discard the feedback message if it applies to another vehicle or may take responsive action if the feedback message applies to the vehicle. For example, the recipient vehicle may display the feedback message, store the feedback message to support related analysis, or relay the feedback message to other vehicles or network devices.
