Autonomous Driving Control Using Driver Seat Position Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous vehicle systems, the risk of accidents increases when the driver's seat position is unsuitable for immediate control takeover during autonomous driving, leading to delayed handover of control authority.
Innovation Solution
An autonomous controller that determines the driver's seat position and angle, restricting seat adjustments and requesting control takeover when the position departs from a safe range, ensuring safe autonomous driving by enabling or disabling the autonomous driving mode based on predetermined thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the autonomous driving function is enabled without monitoring driver's seat position, then the autonomous driving capability is improved, but the safety of autonomous driving deteriorates
Solution Approach 1:
The system performs preliminary monitoring of the driver's seat position before enabling autonomous driving and continues monitoring during operation. The controller checks whether the seat position is within a predetermined safe range before allowing autonomous mode, and can request manual takeover or adjust the seat if the position becomes unsafe during operation.
2Device complexity
If the driver's seat position is not monitored, then the device complexity is reduced, but the risk of accident increases
Solution Approach 1:
The autonomous controller continuously receives feedback from sensors monitoring the driver's seat position and backrest angle. Based on this feedback, the controller determines whether the position is within the safe range and accordingly enables or disables autonomous driving mode, or requests manual takeover when the position becomes unsafe.
3Productivity
If the autonomous driving mode is always enabled, then the productivity is improved, but the reliability deteriorates when driver's seat position is unsafe
Solution Approach 1:
The system dynamically adjusts the autonomous driving mode based on real-time driver's seat position. The controller enables autonomous mode when the seat position is within the safe range and disables or requests manual takeover when the position moves outside the safe range, making the system adaptive to changing conditions.
Data Source
AI summary
The autonomous controller includes: a processor configured to control autonomous driving and determines whether to enable an autonomous driving mode or to convert the autonomous driving mode into a manual driving mode based on a current position of the driver's seat; and a storage configured to store data and an algorithm run by the processor. The processor controls at least one of whether to enable an autonomous driving mode, whether to restrict position adjustment of the driver's seat, or whether to hand over control authority based on a movement position in a forward or backward direction of the driver's seat or an angle of the backrest of the driver's seat.
