Vehicle Display Controller for Automated Driving Assistance Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems fail to effectively notify occupants when automated driving assistance is available before its initiation, leading to a lack of awareness about the vehicle's capability to provide driving assistance.
Innovation Solution
A vehicle control system that includes a display and a display controller to show images related to the vehicle's state and switch display details when a predetermined event occurs, such as an occupant's operation, recognizing external environment elements like other vehicles or obstacles, and displaying information about driving assistance levels before automated driving begins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display switches to automated driving information only when automated driving starts, then the display remains simple and avoids unnecessary information, but the occupant is not notified in advance that driving assistance is available
Solution Approach 1:
The display controller switches to automated driving information display before the automated driving control actually starts, when a predetermined event occurs. This preliminary display action notifies the occupant in advance that driving assistance is available, resolving the information loss problem while maintaining simple display control logic.
2Loss of information
If the display shows detailed automated driving information before driving assistance starts, then the occupant is well-informed about driving assistance capability, but the display may show unnecessary information that could cause distraction
Solution Approach 1:
The display controller selectively switches to show only relevant automated driving information (such as recognition results and assistance availability) rather than all possible information. This localized information display provides necessary capability information while avoiding unnecessary details that could distract the occupant.
3Loss of time
If the display switches to automated driving information earlier than the start of driving assistance, then the occupant receives advance notification, but the timing becomes unclear and may cause confusion
Solution Approach 1:
The display controller uses a predetermined event as a clear trigger condition for switching display information. This event-based feedback mechanism provides unambiguous timing for when driving assistance is available, eliminating confusion about notification timing while ensuring the occupant receives advance notice.

AI summary
A vehicle control system includes a display and a display controller configured to cause the display to display an image related to a state of a vehicle and perform control for switching display details to be displayed on the display when a predetermined event has occurred in the vehicle before driving assistance of the vehicle is started.
