Lane Change Direction Display for Clear Driver Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lane change assist systems do not effectively communicate the direction in which a lane change is possible, leading to user confusion and potential anxiety when lane changes are not performed as expected.
Innovation Solution
A vehicle information output control device that acquires direction information from a lane change assist system and displays a direction image on the vehicle's display units, including a steering image and directional arrows indicating possible lane changes, with highlighted features to indicate the viable directions and synchronized rotation during lane changes, and provides audio feedback when lane changes are not performed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a lane change assist system is activated without displaying direction information, then the system structure remains simple, but the user cannot grasp the direction in which a lane change is possible
Solution Approach 1:
The display information is segmented into distinct directional indicators (left direction image and right direction image) that are separately displayed based on the detected lane change direction. This segmentation allows the system to provide specific directional information without requiring a complex overall display structure, as each direction is represented by a simple, dedicated visual element.
Solution Approach 2:
A display unit acts as an intermediary between the lane change assist system and the user. This intermediary component translates the system's lane change capability into visual direction images that the user can easily understand, thereby providing direction information without requiring direct complexity in the control system itself.
2Loss of information
If the display unit shows detailed direction information, then the user can grasp lane change directions, but the display consistency may be compromised due to frequent updates
Solution Approach 1:
The display unit dynamically updates the direction images based on real-time detection of lane change directions. The system maintains display consistency by using a standardized set of direction images that are selectively activated rather than creating new displays, thus adapting to changing conditions while preserving compositional stability.
Solution Approach 2:
The system applies local quality changes by selectively displaying or highlighting specific direction images (left or right) based on the detected lane change direction, while maintaining the overall display structure and other visual elements consistent. This allows directional information to be updated without compromising overall display consistency.
3Reliability
If the system provides comprehensive visual and audio feedback, then user anxiety is reduced, but the device complexity increases
Solution Approach 1:
The system merges visual feedback (direction images on the display unit) and audio feedback (output from the audio output unit) into a unified notification system. This combination provides comprehensive information to the user through multiple channels, enhancing user confidence and reducing anxiety while managing complexity by coordinating these feedback mechanisms through a single control logic.
Data Source
AI summary
A vehicle information output control device includes a processor. The processor acquires direction information on a direction in which a lane change is possible by activation of a lane change assist system. Based on the direction information, the processor causes a display unit in a vehicle cabin to output a direction image indicating the direction in which the lane change is possible.
