Automated Driving Transition Alerts for Distance Change Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems with no periphery monitoring obligation can cause discomfort due to unexpected changes in vehicle-to-vehicle distance, leading to reduced convenience for drivers.
Innovation Solution
An automated driving control device that switches between driving assistance control with periphery monitoring and autonomous traveling control without monitoring, changes vehicle-to-vehicle distance, and provides notifications to drivers during state shifts, facilitating comfortable transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous traveling control without periphery monitoring is implemented, then automation level is improved, but driver comfort deteriorates due to unexpected vehicle-to-vehicle distance changes
Solution Approach 1:
The system performs preliminary actions by notifying the driver in advance before changing vehicle-to-vehicle distance during autonomous traveling control. The notification is issued before the actual distance change occurs, allowing the driver to mentally prepare for the upcoming change, thus maintaining comfort while enabling automation.
Solution Approach 2:
The system implements feedback by continuously monitoring the traveling control state and issuing notifications when distance changes are about to occur. This feedback loop keeps the driver informed about system actions, reducing surprise and discomfort while maintaining high automation levels.
2Productivity
If vehicle-to-vehicle distance is changed during autonomous traveling control, then automation performance is improved, but driver awareness deteriorates due to lack of notification
Solution Approach 1:
The notification control unit provides feedback to the driver by issuing notifications when vehicle-to-vehicle distance is about to change. This ensures the driver remains informed about automation actions, preventing information loss while maintaining high automation performance.
Solution Approach 2:
The notification control unit acts as an intermediary between the automated driving system and the driver. It translates system actions into driver-friendly notifications, ensuring information is effectively communicated without reducing automation performance.
3Adaptability or versatility
If switching between driving assistance control and autonomous traveling control is enabled, then system versatility is improved, but control stability deteriorates due to frequent state changes
Solution Approach 1:
The system performs preliminary notification before switching between driving assistance control and autonomous traveling control. This advance notice allows the driver to prepare for the transition, maintaining control stability while enabling versatile switching between different control modes.
Solution Approach 2:
The notification control unit applies preliminary anti-action by alerting the driver before control state changes occur. This prevents sudden unexpected transitions that could destabilize the control system, while still allowing versatile switching when needed.
