Autonomous Driving Deactivation via Driver Readiness Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems deactivate immediately upon detecting a driver's intention to switch from autonomous to manual driving, potentially leading to unsafe situations where neither the driver nor the system is in control, causing psychological pressure and unease for the driver.
Innovation Solution
An autonomous driving system that detects a 'deactivating action' from the driver and only switches to manual control after confirming a 'ready state', ensuring the driver is prepared to take over, using sensors to monitor steering, acceleration, braking, and attentiveness to ensure safe transition.

Engineering Contradiction Analysis
1Speed
If the autonomous driving system deactivates immediately upon detecting a driver's operation exceeding a threshold, then the system responds quickly to driver input, but the driver experiences psychological pressure and the vehicle may travel without control if the driver is not ready
Solution Approach 1:
The system performs preliminary detection of the driver's ready state (through steering wheel contact detection, operation detection, or explicit input) before actually deactivating autonomous driving. This preliminary action ensures the driver is prepared to take control before the system relinquishes control, preventing the vehicle from traveling without control.
Solution Approach 2:
The system continuously monitors driver state and provides feedback by detecting whether the driver is ready for manual driving. This feedback mechanism allows the system to understand the driver's preparedness level and adjust the deactivation timing accordingly, reducing psychological pressure while ensuring safety.
2Reliability
If the autonomous driving system waits for driver readiness before deactivation, then the transition is safer and less stressful, but the response time to driver input is delayed
Solution Approach 1:
The system performs preliminary detection of the driver's ready state (through steering wheel contact detection, operation detection, or explicit input) before actually deactivating autonomous driving. This preliminary action ensures the driver is prepared to take control before the system relinquishes control, preventing the vehicle from traveling without control.
Solution Approach 2:
The system dynamically adjusts the deactivation process based on the driver's state. When the driver is detected to be ready (through various detection methods), the system accelerates the deactivation process. This dynamic approach balances safety requirements with responsive timing, minimizing unnecessary delays while ensuring the driver is prepared.

AI summary
An autonomous driving system includes: a driver information acquisition device that acquires driver information indicating an action and a state of a driver of a vehicle; and a control device that performs autonomous driving control that controls autonomous driving of the vehicle. The autonomous driving control includes: deactivating action detection processing that detects, based on the driver information, a deactivating action of the driver to deactivate the autonomous driving; ready state detection processing that detects, based on the driver information, a ready state indicating that the driver is ready for manual driving; and deactivation processing that deactivates the autonomous driving when the ready state is detected after the deactivating action is detected.
