Automated Driving Takeover Refusal and Vehicle Evacuation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving systems face challenges in safely switching from automatic to manual driving modes, particularly when drivers are not fully awake or alert, leading to potential accidents and increased risk of rear-end collisions or traffic congestion.
Innovation Solution
An information processing apparatus and method that includes a takeover abandonment input unit allowing drivers to refuse switching to manual driving, with a data processing unit that acquires driver and environmental information to check a switching point and execute an evacuation process, such as deceleration or stopping, if the driver refuses to switch modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system automatically performs emergency stopping or decelerating when the driver cannot return to manual driving, then driving safety is improved, but rear-end collision risk and traffic congestion increase
Solution Approach 1:
The system performs preliminary actions by notifying the driver in advance before the switching point and providing a grace period for manual driving return. This allows the driver time to wake up and return to driving mode before emergency stopping is necessary, thereby improving safety while avoiding unnecessary emergency maneuvers that could cause rear-end collisions
Solution Approach 2:
The system dynamically adjusts the evacuation process based on real-time driver state monitoring. If the driver returns to manual driving mode within the grace period, the system transitions from emergency stopping to normal operation, thus maintaining safety while preventing harmful emergency maneuvers
2Reliability
If the system frequently executes emergency stop or deceleration to ensure safety, then driving safety is improved, but traffic congestion and rear-end collision risk increase
Solution Approach 1:
The system implements preliminary notification and grace period mechanisms that prevent the need for frequent emergency stops. By giving drivers advance warning and sufficient time to return to manual driving, the system maintains safety without disrupting traffic flow
Solution Approach 2:
The system continuously monitors driver state and provides feedback through notifications. This feedback loop allows the system to adjust its response based on whether the driver returns to manual driving mode, thereby maintaining safety while minimizing unnecessary emergency maneuvers that would disrupt traffic
3Ease of operation
If the driver is allowed to refuse switching to manual driving mode, then driver autonomy is improved, but the ability to ensure safe manual driving operation decreases
Solution Approach 1:
The system performs preliminary monitoring of driver state and provides advance notification before the switching point. This allows the driver to maintain autonomy by deciding whether to return to manual driving, while the system prepares appropriate responses including grace period extension or evacuation processes to ensure safety
Solution Approach 2:
The system provides a grace period as a cushion between the notification and the mandatory switching point. This cushion allows the driver to refuse initial notifications and still have time to return to manual driving safely, balancing autonomy with safety through layered warnings and extended response time

AI summary
Evacuation control such as deceleration or stop of a vehicle is executed in response to an application from a driver of the vehicle for refusal of switching to manual driving. It is a moving apparatus that is switchable between automatic driving and manual driving and includes a driver information acquisition unit that acquires driver information of a driver of the moving apparatus, an environmental information acquisition unit that acquires surrounding information of the moving apparatus, a takeover abandonment input unit that inputs, to a system, takeover refusal information for a driver to refuse driving takeover to change automatic driving of the moving apparatus to manual driving, and a data processing unit that checks a switching point from automatic driving to manual driving on the basis of information acquired by the environmental information acquisition unit and executes a manual driving return request notification to the driver before reaching the switching point, in which the data processing unit further executes an evacuation process of a vehicle in response to a takeover abandonment input.
