Automated Driving Resume Control After Congestion Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems face challenges in ensuring convenience when a vehicle stops due to congestion, as drivers may not know how to proceed without monitoring the periphery, potentially impairing the convenience of eyes-off automated driving.
Innovation Solution
An automated drive control device and program that determines whether an elapsed time after stopping exceeds a predetermined time, allowing automatic resumption of travel without driver input if within the time limit, and requiring driver input for resumption if the time exceeds the limit, ensuring the driver can grasp the situation only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the vehicle stops due to congestion during automated driving, then the automated driving function can operate without driver monitoring, but the driver may not know how to proceed after stopping
Solution Approach 1:
The notification device provides feedback to the driver by notifying them when the vehicle stops due to congestion and when automated resumption will occur. This feedback loop ensures the driver is informed about the system's actions and the current state of automated driving, resolving the contradiction between high automation and driver awareness.
2Ease of operation
If the vehicle automatically resumes travel without driver input after stopping, then convenience is improved, but safety may be compromised if the driver should have been aware of the situation
Solution Approach 1:
The notification device performs preliminary action by informing the driver before the automated resumption occurs. This advance notification allows the driver to mentally prepare and assess the situation, ensuring safety is maintained while still providing the convenience of automated operation.
3Reliability
If the driver is required to monitor periphery during automated driving, then safety is improved, but the convenience of eyes-off automated driving is impaired
Solution Approach 1:
The automated driving system performs self-service by automatically resuming travel after congestion-related stops without requiring driver intervention. This self-service capability maintains safety through automated decision-making while providing the convenience of eyes-off driving, as the system handles the resumption process autonomously.

AI summary
An automated drive control device that enables traveling of a subject vehicle by an automated driving function is provided. The automated drive control device is configured to determine whether an elapsed time after the stop exceeds a predetermined time when the subject vehicle that has been traveling by autonomous traveling control in which a driver of the subject vehicle is not obliged to monitor periphery stops due to congestion, cause an input by the driver to not be required for resuming the traveling of the subject vehicle when the elapsed time does not exceed the predetermined time, and resume the traveling of the subject vehicle on a basis of an input by the driver when the elapsed time exceeds the predetermined time.
