Vehicle Auto-Driving Notification Control for Non-Permission Reasons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic driving systems in vehicles do not effectively notify users of the reasons why automatic driving is not permitted, leading to user confusion and uncertainty about necessary actions.
Innovation Solution
A control device and method that differentiate notifications based on states where automatic driving is permitted, where equipment abnormalities occur, or where it is temporarily not permitted due to reasons other than equipment issues, using visual and auditory cues to inform users of the reason for non-permission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single notification mode is used to indicate whether automatic driving is permitted, then the notification system is simple, but the user cannot recognize the reason why automatic driving cannot be performed
Solution Approach 1:
The notification system is segmented into multiple distinct modes: a first notification mode for equipment abnormalities and a second notification mode for temporary reasons. This segmentation allows the system to convey different types of information (equipment status vs. temporary conditions) through distinct notification patterns, enabling users to recognize the specific reason why automatic driving is not permitted without adding significant complexity to the overall system architecture.
Solution Approach 2:
Different notification modes are applied locally to different situations or conditions. The system uses specific notification characteristics (such as different display patterns, colors, or messages) tailored to the specific condition being communicated - whether it's an equipment abnormality or a temporary restriction. This local differentiation of notification quality enables precise information transmission about the reason for non-permission.
2Loss of information
If multiple notification modes are used to indicate different states of automatic driving permission, then the user can recognize the reason for non-permission, but the notification system becomes more complex
Solution Approach 1:
The notification system dynamically adapts its mode based on the current state of the automatic driving permission conditions. The controller automatically switches between the first notification mode (for equipment abnormalities) and the second notification mode (for temporary reasons) depending on which condition is met. This dynamic behavior allows the system to provide precise information about the reason for non-permission while maintaining a relatively simple underlying system structure that automatically selects the appropriate notification mode.

AI summary
A control device includes a controller configured to perform a notification whether automatic driving of a vehicle is able to be started, in a different mode according to at least either of a first state where the automatic driving is able to be permitted, a second state where the automatic driving is unable to be permitted due to an equipment abnormality, or a third state where the automatic driving is unable to be permitted for a temporary reason without an equipment abnormality.
