Onboard V2X Alert Broadcasting for Vehicle Fault and Driver Misbehavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle communication systems fail to provide timely alerts for vehicle malfunctions and driver misbehaviors, leading to increased collision risks due to delayed message broadcasts occurring only at predefined intervals, which can result in missed alerts and accidents.
Innovation Solution
Implementing an onboard unit in vehicles to detect vehicle malfunctions and driver distractions using sensors and AI/ML algorithms, determining a score level, and broadcasting immediate alert messages via V2X communication interfaces at maximum power to ensure timely warnings to nearby vehicles, pedestrians, and infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alert messages are broadcast only at predefined intervals, then system complexity is reduced and energy consumption is lowered, but alert timeliness deteriorates and collision risks increase
Solution Approach 1:
The patent implements dynamic message broadcasting where the transmission interval is not fixed but adapts based on detected event severity. The system transitions from static periodic broadcasting to dynamic event-driven broadcasting, adjusting message frequency in real-time based on situational urgency, thereby improving alert timeliness without requiring continuously complex system architecture
Solution Approach 2:
The system changes the parameter of message broadcast timing from fixed intervals to variable intervals determined by event score levels. When malfunctions or driver behaviors are detected and scored above thresholds, the system immediately broadcasts alerts regardless of the predefined schedule, effectively changing the temporal parameter of communication based on operational conditions
2Reliability
If immediate alert broadcasting is implemented upon detecting malfunctions or driver misbehavior, then collision risks are reduced, but energy consumption and communication resource usage increase
Solution Approach 1:
The system implements parameter-based filtering where event severity is quantified through scoring mechanisms. Only events exceeding predetermined score thresholds trigger immediate alert broadcasting. This selective approach changes the parameter of alert activation from continuous to conditional, ensuring energy is consumed only when safety-critical situations are detected, not for every sensor event
Solution Approach 2:
The system employs feedback loops where sensor data is continuously analyzed, scored, and compared against thresholds. This feedback mechanism ensures that immediate broadcasting occurs only when the analyzed event feedback indicates genuine safety risks, preventing unnecessary energy consumption from spurious or minor events while maintaining high reliability for actual hazards

AI summary
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes receiving, by an onboard unit (OBU) of a vehicle, sensor data from a plurality of sensors of the vehicle. The process may include determining, by the OBU based on the sensor data, a score level for an event associated with the vehicle. The process may further include determining the score level is greater than a threshold score level and, based on the score level being greater than the threshold score level, broadcasting an alert message related to the event to one or more devices.
