Automated Driving Handover Control for Driver Visual Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional travel support apparatuses do not adequately consider the driver's ability to recognize road conditions when switching from automatic to manual travel mode, potentially leading to risks due to unforeseen obstacles.
Innovation Solution
A moving object travel support apparatus that includes a travel mode determination unit, a scheduled switching point decision unit, and a travel control details decision unit, which estimates the driver's visual recognition condition to determine appropriate travel control details for a smooth transition from automatic to manual travel mode, ensuring the driver can predict and respond to road hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mode is switched from automatic travel to manual travel without considering driver's visual recognition ability, then the switching response is fast and efficient, but the driver may not be able to recognize road conditions and obstacles, leading to safety risks
Solution Approach 1:
The system performs preliminary actions by calculating the manual travel zone and scheduled switching point in advance, and controlling the moving object to travel at a speed that enables the driver to visually recognize the surrounding environment before mode switching occurs. This ensures the driver is prepared for manual travel without abrupt transitions.
Solution Approach 2:
The travel control details decision unit decides travel control details in advance up to the scheduled switching point, ensuring that the moving object reaches the switching point at a speed and position that allows the driver to have adequate visual recognition of road conditions and obstacles before taking over manual control.
2Device complexity
If the driver's visual recognition condition is not considered in mode switching, then the control system is simple and fast, but the driver may take over driving without predicting risks in the manual travel zone
Solution Approach 1:
The system introduces feedback by continuously monitoring the driver's visual recognition condition and using this information to adjust travel control details. The travel control details decision unit decides control parameters based on the calculated manual travel zone and scheduled switching point, ensuring the driver can visually recognize road conditions before mode switching.
Solution Approach 2:
The system performs preliminary calculations of the manual travel zone and scheduled switching point, and controls the moving object's speed and position in advance to ensure the driver can visually recognize the surrounding environment before mode switching occurs.
3Productivity
If the moving object travels at high speed to reach the switching point quickly, then the switching efficiency is improved, but the driver has less time to visually recognize the environment, reducing switching safety
Solution Approach 1:
The system performs preliminary actions by calculating the manual travel zone and scheduled switching point, and controlling the moving object to travel at a speed that enables the driver to visually recognize the surrounding environment before mode switching occurs.
Solution Approach 2:
The system dynamically adjusts the travel control details based on real-time conditions. The travel control details decision unit decides control parameters including speed and position to reach the scheduled switching point, balancing the need for efficient switching with the driver's visual recognition requirements.

AI summary
The present invention supports appropriate switching from an automatic travel mode to a manual travel mode. A moving object travel support apparatus 1 according to the present invention is a moving object travel support apparatus capable of switching between a manual travel mode and an automatic travel mode, and includes: a travel mode determination unit 121 that determines which travel mode is to be selected out of a manual travel mode and an automatic travel mode; a scheduled switching point decision unit 122 that decides a scheduled switching point at which the automatic travel mode is switched to the manual travel mode in a case where the travel mode determination unit selects the manual travel mode; and a travel control details decision unit 124 that decides travel control details at the time of travel in the automatic travel mode up to the scheduled switching point on the basis of a condition of a predetermined manual travel zone including the scheduled switching point out of the manual travel zones on which travel in the selected manual travel mode is scheduled.
