Autonomous Driving Controller for Safe Driver Seat Handover
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 area, ensuring safe transition to manual driving mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous driving function is enabled without monitoring driver's seat position, then the autonomous driving can be performed continuously, but the safety of autonomous driving is compromised and control takeover may be delayed
Solution Approach 1:
The system performs preliminary monitoring of the driver's seat position before enabling autonomous driving and continuously monitors during operation. The safety area is pre-defined, and the system proactively detects when the seat position departs from this area, allowing preventive action to be taken before a safety issue arises, thus maintaining both continuous operation and safety.
Solution Approach 2:
The system implements a feedback mechanism where the autonomous controller continuously monitors the driver's seat position and compares it against the predefined safety area. When the seat position departs from the safety area, the system provides feedback by generating a warning signal and ultimately restricting autonomous driving operation, ensuring safety while allowing continuous operation within safe parameters.
2Reliability
If the driver's seat position is strictly monitored and restricted, then the safety of autonomous driving is improved, but the ease of operation is reduced due to position adjustment restrictions
Solution Approach 1:
The system applies different control strategies based on the local condition of seat position. Within the safety area, the system allows full seat adjustment flexibility for driver comfort. When the seat position departs from the safety area, the system locally applies restrictions only to the extent necessary to bring the position back into the safe range, rather than imposing blanket restrictions on all seat adjustments.
3Reliability
If the autonomous controller hands over control authority to the driver immediately when seat position is unsafe, then the safety is improved, but the productivity is reduced due to interruption of autonomous driving
Solution Approach 1:
The system implements a staged response with periodic escalation. Instead of immediately handing over control, the system first issues a warning signal when the seat position departs from the safety area, allowing the driver a brief period to correct the position. Only if the position remains unsafe after the warning does the system proceed to restrict autonomous driving operation, thus balancing safety with operational efficiency.
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.
