Autonomous Driving Switch Notification for Predicted Interruptions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving systems face interruptions due to unreliable vehicle position information, particularly in areas like tunnels, which can impair the convenience of autonomous driving without periphery monitoring obligations.
Innovation Solution
A presentation control device that determines whether to switch from driving assist control to autonomous traveling control based on the presence of interruption predicted sections and notifies the driver accordingly, canceling notifications when such sections are detected in the travel direction, thereby suppressing the switch to autonomous traveling control and ensuring continued convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system switches to autonomous traveling control, then the driver does not need to monitor periphery, but interruptions occur in areas like tunnels where vehicle position information becomes unreliable
Solution Approach 1:
The system performs preliminary detection of interruption predicted sections (such as tunnels) before the vehicle enters them. When such sections are detected, the notification control unit suppresses notifications about switching to autonomous traveling control, preventing the switch from occurring in the first place. This preliminary action avoids interruptions before they happen.
Solution Approach 2:
The system applies preliminary anti-action by detecting the presence of interruption predicted sections and actively suppressing the switch to autonomous traveling control. This counter-measure prevents the harmful effect of interruption by opposing the automatic switching mechanism when adverse conditions are foreseen.
2Reliability
If the system provides previous notice of cancellation due to tunnel detection, then reliability is maintained, but convenience of autonomous driving is impaired
Solution Approach 1:
Instead of providing previous notice of cancellation, the system performs preliminary detection of interruption predicted sections and suppresses the switch to autonomous traveling control before the vehicle enters the tunnel. This prevents the interruption scenario entirely, maintaining both reliability and convenience.
3Ease of operation
If the system allows switching to autonomous traveling control without restrictions, then ease of operation improves, but interruptions occur when vehicle position information reliability decreases
Solution Approach 1:
The system uses feedback from the detection unit that identifies interruption predicted sections. This feedback loop allows the notification control unit to make informed decisions about whether to permit switching to autonomous traveling control, balancing ease of operation with reliability considerations.
Solution Approach 2:
The system performs preliminary detection of adverse conditions (tunnels, areas with unreliable position information) before allowing switching. By detecting these sections in advance, the system can prevent switches that would lead to interruptions, maintaining both ease of operation and reliability.

AI summary
A presentation control device, which controls information presentation relating to autonomous driving function of a vehicle, is configured to: grasp whether a switch from a driving assist control, which requires a periphery monitoring by a driver as an obligation, to an autonomous traveling control, which does not require the periphery monitoring by the driver as the obligation, becomes possible; notify switch possible information when an interruption predicted section does not exist in a predetermined range defined in a traveling direction of the vehicle from a position where the switch to the autonomous traveling control becomes possible, the interruption predicted section being a section in which an interruption of the autonomous traveling control is predicted; and cancel a notification of the switch possible information when the interruption predicted section exists in the predetermined range.
