Vehicle Control Device Prioritizing Lane Change Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle automatic control systems, frequent lane change notifications can confuse drivers by making it difficult for them to determine the original traffic lane and scheduled route to the destination.
Innovation Solution
A vehicle control device assesses the necessity of lane changes based on scheduled routes and environmental information, prioritizing notifications for changes that are closer to the destination, involve shorter distances, and require immediate action, while suppressing notifications for less critical changes, using a processor to determine and manage notification priorities and methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver is notified of every planned lane change, then the driver is informed of all lane changes, but the driver becomes confused and unable to ascertain the original traffic lane and scheduled route
Solution Approach 1:
The notification system applies different notification characteristics to different lane changes based on their local context and importance. Critical lane changes (those necessary for following the scheduled route) receive prominent notifications, while less important lane changes receive suppressed or reduced notifications. This selective notification approach maintains driver awareness of essential lane changes without overwhelming the driver with unnecessary information.
Solution Approach 2:
The system extracts and identifies the essential lane changes from the complete set of all planned lane changes. By determining which lane changes are necessary for following the scheduled route and which are not, the system separates critical notifications from non-critical ones, notifying the driver only of the extracted essential lane changes rather than all lane changes.
2Adaptability or versatility
If the vehicle executes frequent lane changes to follow the scheduled route, then the vehicle can navigate complex road situations, but the driver becomes unable to keep track of the scheduled route
Solution Approach 1:
The system performs preliminary determination of notification priority before executing lane changes. By assessing whether each planned lane change is necessary for following the scheduled route and determining its notification priority in advance, the system prepares appropriate notifications that will help the driver understand the purpose and necessity of upcoming lane changes, preventing information loss about the scheduled route.
Solution Approach 2:
The notification system provides feedback to the driver about the rationale and necessity of lane changes. By notifying the driver of lane changes that are necessary for following the scheduled route and suppressing notifications for non-necessary lane changes, the system gives the driver feedback about the vehicle's navigation decisions, helping the driver maintain understanding of the scheduled route despite frequent lane changes.

AI summary
A vehicle control device has a processor configured to assess whether or not a lane change is necessary based on a scheduled route and surrounding environment information for a vehicle and select a traffic lane of the road, to produce a driving lane plan showing the scheduled driving lane, determine the notification priority representing the priority for notifying the driver of the planned lane change, based on at least one item from among the scheduled route, and the result of assessing whether or not the planned lane change is included in a plurality of continuous planned lane changes to be executed for a common purpose, when it has been planned to execute a lane change and suppress notification to the driver of planned lane changes with low notification priority compared to notification to the driver of planned lane changes with high notification priority, using a notification unit.
