Autonomous Vehicle Action Schedule Notification for Consecutive Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems only inform surrounding vehicles of immediate actions, leading to unexpected vehicle movements and increased accident risk due to lack of awareness of subsequent actions.
Innovation Solution
An action schedule notification device and method for vehicles capable of autonomous driving, which determines and notifies two or more consecutive action schedules to surrounding vehicles through display or voice, including lane changes, merges, and route transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only immediate action content is notified to surrounding vehicles, then notification simplicity is maintained, but surrounding vehicles cannot anticipate future actions leading to unexpected movements and increased accident risk
Solution Approach 1:
The notification device performs preliminary action by notifying surrounding vehicles of future action schedules before the vehicle actually executes them. The processor notifies not only the current action but also subsequent actions (e.g., lane changes, turns, merges) that the vehicle plans to perform, allowing other drivers to anticipate and prepare for these movements in advance, thereby preventing accidents caused by unexpected vehicle behavior.
2Reliability
If multiple consecutive action schedules are notified, then surrounding vehicles can anticipate future actions improving safety, but notification complexity increases
Solution Approach 1:
The notification system applies segmentation by dividing the action schedule information into discrete, manageable units. The processor identifies and notifies specific consecutive actions (such as individual lane changes, turns, or merges) rather than overwhelming surrounding vehicles with all possible future actions at once. This segmented approach maintains clarity while providing sufficient advance notice for safety.
Solution Approach 2:
The system extracts only the essential consecutive action schedules that are most relevant for surrounding vehicles to know. Rather than notifying all possible future actions, the processor selectively extracts and notifies the key upcoming actions that directly impact other road users, simplifying the notification while maintaining safety benefits.
3Reliability
If action schedules are notified in mixed traffic areas with manual vehicles, then awareness and safety improve, but the system must adapt to diverse driver behaviors and attention levels
Solution Approach 1:
In mixed traffic areas, the notification device performs preliminary action by providing advance notice of autonomous vehicle actions to manual drivers who may not have the same level of situational awareness. This early notification compensates for the limited attention and processing capacity of human drivers, giving them extra time to react appropriately to the autonomous vehicle's planned maneuvers.

AI summary
The processor 162 of ECU 160 is configured to determine an action schedule of the vehicle capable of autonomous driving and notify two or more consecutive action schedules to surrounding other vehicles, and is configured to perform at least one of notifying the two or more consecutive action schedules from the vehicle to the outside by display or voice or having the two or more consecutive action schedules notified by display or voice in the surrounding other vehicles.
