In-Vehicle Lane Marking Display Timing for Lane-Keeping Readiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display systems display lane markings for lane-keeping control without immediate operation, causing a feeling of incompatibility for occupants as the control is not yet active.
Innovation Solution
An in-vehicle display device that recognizes lane markings and only displays them after a predetermined standby time has elapsed once operational conditions for lane-keeping control are met, adjusting this time based on road type, lane marking length, and vehicle speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the lane marking is displayed immediately after recognition starts, then the display responsiveness is improved, but the occupant experiences a feeling of incompatibility because lane-keeping control is not yet operational
Solution Approach 1:
The system performs preliminary recognition of lane markings and evaluates operation conditions in advance, but delays the actual display until the standby time elapses and control is confirmed ready. This preliminary preparation allows the system to be ready to display immediately when conditions are met, maintaining responsiveness while ensuring control operational status matches display content.
Solution Approach 2:
The display timing is made dynamic rather than fixed - it adapts based on whether operation conditions are satisfied. The system continuously monitors conditions and adjusts display timing accordingly, creating a flexible response that balances speed and reliability based on real-time system state.
2Reliability
If the display standby time is increased to ensure control operational status matches display content, then occupant trust is improved, but the display responsiveness deteriorates
Solution Approach 1:
The standby time parameter is optimized to a specific duration that balances trust and responsiveness. Rather than using a fixed long delay, the system uses a calibrated standby time that is sufficient to ensure control readiness while minimizing unnecessary delay, achieving optimal trade-off between the two competing requirements.
3Duration of action of stationary object
If the lane marking is displayed before lane-keeping control operation is confirmed, then display continuity is improved, but recognition stability deteriorates
Solution Approach 1:
The system performs preliminary evaluation of operation conditions including recognition stability before enabling display. By checking conditions in advance and only displaying when stability is confirmed, the system ensures that displayed lane markings are based on stable recognition, preventing display interruptions caused by unstable recognition later.

AI summary
The in-vehicle display includes: a recognition unit configured to recognize a lane marking of a traveling lane based on a captured image of a camera; a determination unit configured to determine whether or not an operation condition of lane-keeping control is satisfied; and a display controller configured to display the recognized lane marking on a display. The display controller is configured to display the lane marking after a display standby time elapses when the determination unit determines that the operation condition is satisfied when the recognition unit starts the recognition of the lane marking.
