Autonomous Driving Warning Routing for Portable Terminal Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in providing appropriate warnings during autonomous driving, as notifications to portable terminals can cause drivers to search for the device, leading to delayed responses and annoyance, especially when the driver is engaged in secondary tasks or the device is not in a fixed position.
Innovation Solution
A control device and method that selectively disable notifications to portable terminals under certain conditions, such as when the driver is engaged in secondary tasks, the terminal is not in a predetermined position, or multiple terminals are present, ensuring warnings are provided only to the onboard terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification of warning is provided to portable terminal during autonomous driving, then driver can be alerted of driving changes, but driver may search for portable terminal causing delay in response
Solution Approach 1:
The notification system dynamically adjusts the notification destination based on real-time detection of driver state and portable terminal position. When driver distraction is detected or terminal position is unfavorable, notifications are redirected from portable terminal to onboard terminal, optimizing response time while maintaining warning reliability.
Solution Approach 2:
The onboard terminal serves as an intermediary notification device when portable terminal notification is inappropriate. This mediator ensures warning delivery through an alternative channel that does not cause driver distraction, resolving the contradiction between reliable notification and rapid response.
2Reliability
If notification is constantly provided to portable terminal inside vehicle, then driver receives continuous warnings, but this becomes irksome to driver
Solution Approach 1:
The system continuously monitors driver state and terminal position, providing feedback to adjust notification behavior. This feedback mechanism prevents excessive or inappropriate notifications to portable terminal, reducing driver annoyance while maintaining essential warning delivery through selective notification routing.
3Reliability
If notification is provided to portable terminal when driver is performing secondary task, then driver can be alerted of driving changes, but driver may be distracted from secondary task causing delayed response
Solution Approach 1:
The notification system dynamically responds to driver task state. When secondary task execution is detected, the system adjusts notification routing away from portable terminal to prevent distraction, maintaining warning reliability through alternative channels while preserving driver task efficiency.
4Reliability
If notification is provided to portable terminal when terminal is not in predetermined position, then driver can receive warnings, but driver may need to search for terminal causing response delay
Solution Approach 1:
The system performs preliminary detection of portable terminal position before issuing notifications. When terminal is not in predetermined position, notifications are preemptively redirected to onboard terminal, eliminating the need for driver search and ensuring immediate response capability.
Data Source
AI summary
A control device includes a first processor. The first processor is configured to provide notification of a warning during autonomous driving to a first display unit of an onboard terminal installed in a vehicle; provide notification of the warning to a second display unit at a portable terminal carried by a vehicle occupant, via a second processor at the portable terminal; and in a case in which a predetermined condition has been satisfied, disable notification of the warning to the portable terminal and provide notification of the warning to the onboard terminal.
