Vehicle Seat Repositioning for Safe Autonomous-to-Manual Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in transferring travel control rights from an autonomous driving system to a driver when the driver is unable to rapidly receive them, leading to potential accidents, especially when the driver is in a state where manual control is difficult.
Innovation Solution
A device and method that includes a storage unit to store seat and steering wheel locations and a controller to adjust these positions based on predefined or driver-set locations, ensuring the driver can immediately assume control by setting the seat and steering wheel to optimal positions for manual driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system transfers travel control right to the driver during autonomous driving, then the driver can take over manual control, but the driver may not be able to rapidly receive control right due to unsuitable seat position, leading to delayed response and potential accidents
Solution Approach 1:
The system performs preliminary actions by storing the driver's preferred seat location in advance before autonomous driving begins. When control right transfer is needed, the seat is automatically adjusted to the pre-stored location, eliminating the time delay that would occur if the driver had to manually adjust the seat first. This preliminary preparation of the seat position ensures the driver can immediately assume control when needed.
2Ease of operation
If the seat position is adjusted automatically during autonomous driving, then the driver can be in a ready state for manual control, but the driver's personal preference for seat location may not be considered
Solution Approach 1:
The system incorporates feedback by detecting and storing the driver's manually adjusted seat location during operation. This feedback loop allows the system to learn and remember the driver's preferred position. When autonomous driving occurs and control transfer is needed, the seat is adjusted to this stored preferred location, thus accommodating driver preference while maintaining readiness for manual control.
3Adaptability or versatility
If multiple seat locations are stored for different scenarios, then the system can adapt to various driving conditions, but the device complexity increases
Solution Approach 1:
The control system achieves multi-functionality by using a single seat control mechanism that serves multiple purposes: it can adjust to pre-stored preferred locations, automatically position the seat for optimal manual control readiness, and adapt to different driving scenarios (autonomous vs. manual). This universal approach allows the system to handle various driving conditions without requiring separate complex adjustment mechanisms for each scenario.

AI summary
A device for controlling travel of a vehicle includes: a storage that stores at least one of a first seat location before an autonomous driving, a second seat location set by a driver, or a third seat location in a current state; and a controller that controls a seat of the vehicle based on the seat location stored in the storage when a driving state of the vehicle is switched from an autonomous driving state to a manual driving state by transferring a control right of the vehicle to the driver. The device may allow the driver to immediately receive the control right when the control right of the vehicle is transferred to the driver, so that the transfer of the control right may be performed safely.
