Lane Change Display Marking for Driver Unease Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of vehicles capable of automatic lane changes often feel uneasy due to uncertainty about when and where the lane change will occur, especially when surrounding vehicles are involved.
Innovation Solution
A vehicle system equipped with an object recognition device to calculate the relative position of surrounding vehicles and a display device that shows a lane change mark on an information display screen, adjusting its position based on the relative position of surrounding vehicles, allowing drivers to easily understand when and where the lane change will take place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic lane change function is implemented, then driving automation is improved, but driver anxiety increases due to uncertainty about lane change timing and position
Solution Approach 1:
The system provides continuous visual feedback to the driver by displaying the lane change mark that moves in real-time according to the calculated lane change position. This feedback loop eliminates uncertainty by showing the driver exactly when and where the lane change will occur, thereby reducing driver anxiety while maintaining automation.
Solution Approach 2:
The lane change mark serves as an intermediary visual element between the automated lane change system and the driver. It translates the system's internal decision about lane change timing and position into a comprehensible visual representation that the driver can easily understand, bridging the information gap that causes anxiety.
2Loss of information
If lane change mark position is adjusted according to surrounding vehicle relative position, then information clarity is improved, but display complexity increases
Solution Approach 1:
The lane change mark is implemented as a dynamic display element whose position changes automatically based on the calculated lane change position and surrounding vehicle relative positions. This dynamic adjustment provides clear, context-aware information without requiring complex manual configuration or multiple static display elements.

AI summary
A vehicle reducing unease of a driver during driver assistance, provided with a display device configured to display a surrounding vehicle together with a host vehicle at a relative position calculated by an object recognition device, display a mark showing that a lane change is planned to be performed at a predetermined space for performing a lane change in a destination driving lane which is a destination for a lane change when an automatic lane change is planned to be performed, and make a position of the mark change in accordance with the relative position of the surrounding vehicle when there is a surrounding vehicle present having an effect on a lane change in the destination driving lane.
