Notification Server for Automated Driving Mode Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for automated driving vehicles lack effective methods to seamlessly transition between automated and manual driving modes, failing to provide timely and relevant notifications to occupants, which can lead to decreased driver attention and increased safety risks.
Innovation Solution
A system comprising a movable object, a notification server, and a content server connected via a network, where the notification server generates and manages notification plans based on automated driving levels, switching points, and occupant information, presenting timely and appropriate notifications to the driver through a human-machine interface, including audio and image information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated driving mode is implemented, then driving automation level is improved, but driver attention and safety monitoring deteriorate
Solution Approach 1:
The notification server generates notification plans in advance based on automated driving level information, switching point information, and occupant information. Notifications are prepared beforehand to alert drivers before automated driving mode transitions occur, ensuring driver attention is maintained without compromising automation functionality.
Solution Approach 2:
The system continuously monitors automated driving level information and occupant information, using this feedback to dynamically adjust notification plans. The notification server receives updates about driving mode changes and automatically modifies notification timing and content to maintain appropriate driver engagement while preserving automation benefits.
2Loss of information
If notification plans are generated based on multiple parameters, then notification relevance is improved, but system complexity increases
Solution Approach 1:
The notification server acts as an intermediary component that receives automated driving level information from the automated driving system and occupant information from separate sources. It processes these inputs and generates appropriate notification plans, simplifying the overall system architecture by centralizing notification logic in a dedicated server rather than distributing complexity across multiple systems.

AI summary
A control apparatus for controlling notification data presented to an occupant of a movable object having an automated driving function. The control apparatus includes a travel road specification unit configured to specify a road scheduled to be travelled by the movable object corresponding to a destination set for the movable object. The control apparatus includes a setting unit configured to set, according to the road scheduled to be travelled, a switching recommendation point for switching from automated drive to driver-led manual drive on the road scheduled to be travelled, and estimate a scheduled passing time instant at which the movable object passes the switching recommendation point. The control apparatus includes a notification plan generation unit configured to generate a notification plan for presenting predetermined notification data to the occupant of the movable object according to the switching recommendation point and the scheduled passing time instant.
