Vehicle Deceleration Safety Trigger With Driver Responsiveness Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle safety systems either react too slowly to sudden driver illness or prematurely initiate safety procedures, leading to false positives and interruptions in normal driving.
Innovation Solution
A method that initiates a safety procedure for decelerating a vehicle based on driving parameters and driver awareness, including a driver responsiveness check, to ensure accurate triggering only when necessary, using sensors and interfaces to assess driver condition and vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety procedures are initiated quickly based on driving parameters, then driver safety is improved, but false positive triggers increase and normal driving is interrupted
Solution Approach 1:
The patent introduces a driver responsiveness check as an intermediary step between detecting abnormal driving behavior and initiating safety procedures. This mediator verifies whether the driver is actually unresponsive before triggering the safety procedure, thereby reducing false positives while maintaining safety. The check uses user interfaces (visual, acoustic, or haptic) to test driver responsiveness without immediately initiating deceleration.
2Reliability
If driver responsiveness checks are added to verify driver condition, then false positive triggers are reduced, but system complexity increases
Solution Approach 1:
The patent employs existing user interfaces (visual displays, acoustic speakers, haptic feedback systems) for multiple purposes - both for normal vehicle operation and for conducting driver responsiveness checks. This multi-functionality approach allows the system to verify driver condition without adding dedicated hardware, thereby reducing the increase in system complexity while maintaining high accuracy in safety procedure triggering.

AI summary
The disclosure relates to A method (100) for initiating a safety procedure (108) for decelerating a vehicle (10), wherein the method comprises: - obtaining first data indicative of at least one driving parameter of the vehicle (10), - obtaining second data indicative of a driver awareness of a driver of the vehicle (10), - initiating a driver responsiveness check (106) based on the first data and the second data, and - initiating the safety procedure (108) if the driver responsiveness check (106) is indicative of a fail of the driver responsiveness check (106).
