Autonomous Overtaking Control for Passenger Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems often cause stressful or frightening overtaking scenarios for passengers when attempting to change lanes, especially if the vehicle is hindered from returning to its original lane during an overtaking maneuver.
Innovation Solution
An automated driving system that includes sensors and an electronic control device to detect vehicle position and environment characteristics, enabling autonomous overtaking only when predetermined conditions are met, such as safe lane return probability and available overtaking distance, thereby disabling overtaking functionality if these conditions are not satisfied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous overtaking functionality is enabled to improve driving efficiency and reduce manual intervention, then productivity increases, but passenger stress and safety perception deteriorate when lane return is hindered
Solution Approach 1:
The system performs preliminary assessment of lane return conditions before executing autonomous overtaking. The electronic control device evaluates whether the vehicle can successfully return to its original lane after overtaking, and only permits overtaking if this condition is satisfied. This prevents stressful situations where the vehicle is hindered from returning to its original lane during an overtaking maneuver.
2Ease of operation
If autonomous overtaking is implemented to reduce driver workload, then ease of operation improves, but system reliability decreases due to unpredictable stressful scenarios
Solution Approach 1:
The system continuously monitors lane conditions and vehicle position to determine whether lane return is possible. The electronic control device uses sensor data to assess the feasibility of returning to the original lane, and adjusts autonomous overtaking execution accordingly. This feedback mechanism ensures predictable and reliable autonomous driving behavior by preventing overtaking maneuvers that would lead to stressful or unsafe situations.
