Autonomous Driving Plan Adherence Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems fail to provide drivers with a sense of security by not notifying them whether the vehicle is performing autonomous driving according to a created traveling plan.
Innovation Solution
An autonomous driving system that includes a traveling plan creation section, a traveling state acquisition section, a determination section, and a notification control section to verify and notify the driver if the autonomous driving operation is performed according to the planned route, using a navigation device, a locator device, and a traveling track management device to monitor and report the actual traveling state against the planned state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous driving system notifies only information not used in driving operation determination, then information overload to the driver is reduced, but the driver's sense of security is insufficient
Solution Approach 1:
The notification system segments information into two categories: information used for driving operation determination and information not used for driving operation determination. This segmentation allows the system to selectively notify the driver about plan adherence status separately from other navigation information, providing security assurance without causing information overload.
Solution Approach 2:
The system implements a feedback mechanism where the actual traveling state is continuously verified against the traveling plan, and the determination result is notified to the driver. This feedback loop provides the driver with real-time information about whether the autonomous driving is following the planned route, enhancing their sense of security without requiring constant manual monitoring.
2Loss of information
If the autonomous driving system notifies all generated information to the driver, then complete information transparency is achieved, but the driver experiences information overload
Solution Approach 1:
The system extracts and notifies only the critical information regarding plan adherence status from the complete set of generated information. By taking out specifically the determination result that indicates whether actual traveling matches the traveling plan, the system provides essential transparency without overwhelming the driver with all raw data.
Solution Approach 2:
Instead of notifying all generated information (excessive action), the system applies partial action by selectively notifying only the determination result about plan adherence. This partial notification approach provides sufficient information for the driver to assess system performance without the excessive burden of processing all available data.

AI summary
An autonomous driving system includes: a traveling plan creation section that creates a traveling plan of an autonomous driving operation; a traveling state acquisition section that acquires an actual traveling state in the autonomous driving operation; a determination section that verifies the actual traveling state in the autonomous driving operation with the traveling plan of the autonomous driving operation, and determines whether the autonomous driving operation is performed according to the traveling plan; and a notification control section that notifies a determination result of the determination section. The autonomous driving system gives the driver a sense of security.
