Intersection Driver Prompting in Automated Vehicle Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems lack effective mechanisms to prompt drivers for assistance at intersections, where disturbances are common, potentially leading to safety issues due to the absence of driver monitoring during automated driving operations.
Innovation Solution
A vehicle notification control device and method that identifies predetermined operations at intersections and provides notifications to drivers to assist with passing through the intersection, using a system comprising a human machine interface control unit, communication module, locator, map database, vehicle state sensor, surrounding monitoring sensor, vehicle control ECU, and notification device to prompt drivers for monitoring and potential manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving is performed at intersections without driver monitoring, then automation level is improved, but safety is worsened due to lack of driver assistance
Solution Approach 1:
The system implements feedback by detecting predetermined operations (right/left turns) at intersections and providing notifications to the driver. The notification device alerts the driver when automated driving is performed at an intersection, prompting the driver to monitor the situation and provide assistance if needed. This feedback loop maintains high automation levels while ensuring driver awareness and safety.
2Reliability
If driver assistance is prompted during automated driving at intersections, then safety is improved, but device complexity increases due to additional notification systems
Solution Approach 1:
The notification device serves multiple functions: it detects predetermined operations, determines when notifications are necessary, and provides alerts to drivers. By integrating these functions into a single multi-functional system rather than separate components, the patent reduces overall system complexity while maintaining safety improvements.
3Ease of operation
If notifications are provided to prompt driver assistance, then driver engagement is improved, but information processing complexity increases
Solution Approach 1:
The system applies local quality by providing notifications specifically for predetermined operations (right/left turns) at intersections rather than continuously notifying the driver for all automated driving actions. This targeted approach enhances driver engagement for critical situations while minimizing unnecessary information processing and maintaining ease of operation.

AI summary
Disclosed is a technique of notification control for a vehicle configured to execute automated driving. In the technique, a predetermined operation of the vehicle to be executed in an intersection is identified. A notification related to the predetermined operation is made during automated driving of the vehicle based on the identifying the predetermined operation. The notification prompts a driver of the vehicle to assist in passing the intersection.
