Autonomous Lane Change Control for Driver Steering Intervention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lane change assisting devices for autonomous driving fail to effectively manage driver steering interventions during autonomous lane changes, leading to frequent cancellation of autonomous driving mode, which can annoy drivers, or continued operation that does not align with the driver's intentions, causing discomfort.
Innovation Solution
A control device for vehicle traveling that prioritizes driver steering interventions over autonomous lane change control, allowing the driver to take control immediately and announces termination of autonomous driving when the driver's intentions diverge from the autonomous system's intentions, ensuring the driver's intentions are respected without causing annoyance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the autonomous driving mode is canceled whenever there is a steering intervention by the driver, then the driver's intention is respected, but frequent cancellation causes annoyance to the driver
Solution Approach 1:
The system continuously monitors steering interventions and provides feedback by announcing termination of autonomous driving only when the stop condition is established, allowing the driver to understand system status while avoiding unnecessary cancellations
Solution Approach 2:
The system dynamically adjusts its response to steering interventions based on the establishment of stop conditions, transitioning between maintaining autonomous driving mode and announcing termination based on real-time conditions
2Ease of operation
If the autonomous driving mode is never canceled at all times, then driver annoyance is reduced, but the driver may feel discomfort when autonomous driving does not align with driver intention
Solution Approach 1:
The system provides feedback to the driver by announcing termination when the stop condition is established, ensuring the driver is informed when autonomous driving should end while maintaining operation in other cases
Solution Approach 2:
The stop condition establishment acts as an intermediary criterion that mediates between continuous autonomous operation and cancellation, providing an objective basis for termination decisions
3Ease of operation
If the system prioritizes driver steering intervention, then the driver can take control immediately, but the autonomous driving mode may be canceled inappropriately
Solution Approach 1:
The system preliminarily establishes stop conditions before canceling autonomous driving mode, ensuring that cancellation only occurs when predetermined safety or operational criteria are met
Solution Approach 2:
The system uses feedback from stop condition monitoring to determine whether to maintain or terminate autonomous driving mode, ensuring reliable and appropriate mode management

AI summary
The autonomous LC control is started in response to receiving a start instruction of autonomous lane change. When the driver performs a steering intervention in a same direction as a direction of steering requested by the autonomous LC control, and establishment of a stop condition of lane change is not recognized, during execution of the autonomous LC control, the autonomous driving control is continued. When the steering intervention in the same direction is performed, and establishment of the stop condition is recognized, during execution of the autonomous LC control, termination of the autonomous driving control is announced.
