Vehicle Display Icons for Driver-Assistance Deceleration Reasons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems do not provide occupants with the reason for deceleration performed by driver assistance, limiting their understanding of the deceleration state.
Innovation Solution
A vehicle display device and method that acquires and displays a deceleration state and reason for deceleration using a processor to show a deceleration image and a reason image, such as an icon, on a vehicle display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance performs deceleration automatically, then vehicle safety and control are improved, but the occupant's understanding of the deceleration reason deteriorates
Solution Approach 1:
The system provides feedback to the occupant by displaying the reason for deceleration through reason images (icons) on the display unit. This feedback mechanism ensures that while the driver assistance system autonomously controls deceleration, the occupant simultaneously receives information about why the deceleration is being performed, maintaining both safety and understanding.
Solution Approach 2:
The notification device acts as an intermediary between the driver assistance system and the occupant. It translates the internal decision-making process of the automated system into visual representations (deceleration images and reason images) that the occupant can understand, bridging the gap between automated control and human comprehension.
2Loss of information
If the system displays detailed deceleration information, then occupant understanding is improved, but the display complexity increases
Solution Approach 1:
The system uses visual differentiation through distinct image types (deceleration images showing vehicle icons and reason images showing symbolic icons) to convey different types of information. This visual coding allows the display to communicate complex deceleration reasons without requiring text or detailed explanations, maintaining simplicity while improving understanding.
Solution Approach 2:
The system uses symbolic icon representations (reason images) that copy or represent the essence of deceleration reasons in a simplified visual form. Rather than displaying detailed textual explanations, the system uses iconic representations that convey the meaning of deceleration causes (such as pedestrian detection, intersection ahead, etc.) in a visually intuitive and space-efficient manner.
Data Source
AI summary
A vehicle display device includes a processor, the processor being configured to acquire a deceleration state of a vehicle achieved by driver assistance and a reason for decelerating the vehicle, and cause a display to display a deceleration image indicating that the vehicle is decelerating and a reason image indicating the reason, based on the acquired deceleration state and the acquired reason.
