V2V Driver Messenger for Cooperative Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected and autonomous vehicles lack effective communication technologies to share driving intentions and scenarios, leading to aggressive driving behaviors and increased road accidents, as existing sensor data alone is insufficient for situational awareness and safe decision-making.
Innovation Solution
The Driver Messenger System, which uses Basic Safety Messages to update local object maps and identify potential target vehicles, sending personalized Driver Intent Messages to prevent misunderstandings and conflicts, thereby enhancing on-road safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data alone is used for situational awareness, then the system complexity is reduced, but the reliability of safe decision-making deteriorates due to insufficient information
Solution Approach 1:
The patent introduces V2V communication messages as an intermediary to transfer driving intention information between vehicles. These messages serve as a mediator that complements sensor data by providing explicit intent information (lane change, turning, stopping) that sensors cannot directly detect, thereby improving situational awareness and decision-making reliability without significantly increasing system complexity
Solution Approach 2:
The patent segments information acquisition into two independent channels: sensor-based environmental perception and communication-based intention sharing. This segmentation allows the system to process different types of information through dedicated modules (sensor processing module and message processing module), improving overall information completeness while maintaining manageable system complexity
2Reliability
If communication technology is implemented to share driving intentions, then road safety is improved, but the device complexity increases due to additional communication systems
Solution Approach 1:
The patent designs the message processing module to handle multiple types of V2V messages (lane change intent, turning intent, stopping intent, emergency braking) through a unified processing framework. This multi-functional approach allows a single communication system to address various safety scenarios, improving road safety while avoiding the need for separate specialized systems for each message type, thus controlling device complexity
3Productivity
If sensor data only is used, then the ease of operation is maintained, but the productivity of conflict prevention deteriorates due to lack of intention sharing
Solution Approach 1:
The system implements automated conflict prevention by having the message processing module automatically analyze received V2V messages, identify potential conflicts, and trigger appropriate safety responses without requiring manual driver intervention. This self-service approach improves conflict prevention productivity while maintaining ease of operation, as the system handles complex analysis and decision-making autonomously

AI summary
A computer device is provided. The computer device includes at least one processor and at least one memory device. The computer device is associated with a host vehicle. The at least one processor is programmed to: receive sensor information from one or more sensors associated with the host vehicle; build a local object map of the surroundings of the host vehicle based upon the received sensor information; identify a driving scenario based on the local object map; identify a target vehicle that will be affected by the identified driving scenario; and transmit one or more messages to the target vehicle about the detected driving scenario.
