Vehicle Control Lockout for Unintentional Re-Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems, such as lane keeping assist and adaptive cruise control, can unintentionally re-engage after being disengaged, leading to miscommunication with the vehicle operator and potential safety hazards.
Innovation Solution
A system that activates a lockout period upon disengagement, preventing the vehicle control system from re-engaging during this period, using sensors and software to determine the length of the lockout period based on system characteristics, risk level, user preference, and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a vehicle control system allows immediate re-engagement after disengagement, then the system responds quickly to operator inputs, but the system risks unintentional re-engagement causing miscommunication between operator and vehicle
Solution Approach 1:
The system implements a lockout period that is activated in advance when the vehicle control system is disengaged. This preliminary action prevents any re-engagement attempts during the lockout period, ensuring that the operator has intentional control over re-engagement and eliminating unintentional re-engagement risks.
2Reliability
If a lockout period is implemented to prevent unintentional re-engagement, then control reliability improves, but the system response time to operator inputs increases
Solution Approach 1:
The lockout period duration is made dynamic rather than fixed. The system adjusts the lockout period length based on operational context, allowing shorter lockout periods when quick response is needed and longer lockout periods when prevention of unintentional re-engagement is prioritized. This dynamic adjustment optimizes both reliability and response time.
