Vehicle Deceleration Safety Trigger Using Driver Responsiveness Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles often react too slowly to sudden driver illnesses causing unintentional acceleration or prematurely initiate safety procedures, leading to safety inefficiencies and disruptions.
Innovation Solution
A method for initiating a safety procedure based on driving parameters and driver awareness, including a driver responsiveness check to ensure accurate triggering of deceleration only when necessary, using sensors and interfaces to monitor and respond to driver state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety procedures are initiated based on abnormal driving behavior detection, then driver safety is improved, but false positive triggers occur that prematurely force the vehicle to stop
Solution Approach 1:
The system implements a feedback mechanism through driver responsiveness checks. When abnormal driving behavior is detected, the system issues a challenge to the driver and waits for a response. This feedback loop allows the system to verify whether the abnormal behavior is intentional (driver responds) or due to sudden illness (driver does not respond), thereby reducing false positive triggers while maintaining safety.
Solution Approach 2:
The system performs a preliminary driver responsiveness check before initiating the safety procedure. This preliminary action involves detecting abnormal driving behavior first, then challenging the driver to respond, and only if the driver fails to respond does the system proceed to force the vehicle to stop. This staged approach prevents premature stopping while ensuring safety when truly needed.
2Speed
If vehicles react quickly to sudden driver illness, then safety is improved, but the system may prematurely initiate safety procedures for healthy drivers
Solution Approach 1:
The system uses feedback through driver responsiveness checks to distinguish between sudden illness and intentional abnormal driving. When abnormal behavior is detected, the system challenges the driver and waits for a response. A lack of response indicates sudden illness requiring immediate safety intervention, while a response indicates intentional behavior allowing continued driving. This resolves the contradiction by enabling quick reaction only when truly necessary.
Solution Approach 2:
The system dynamically adjusts its response based on driver feedback. If the driver responds to the challenge, the system maintains normal operation. If the driver does not respond, the system quickly initiates safety procedures. This dynamic adaptation allows the system to react quickly to actual emergencies while avoiding premature triggers for healthy drivers.
3Ease of operation
If the gas pedal threshold for overriding safety interventions is set low, then driver control is improved, but unintentional acceleration during sudden illness cannot be prevented
Solution Approach 1:
The system performs a preliminary check of driver awareness and responsiveness before allowing gas pedal input to override safety interventions. By detecting abnormal driving behavior first and challenging the driver to respond, the system ensures that only responsive drivers can override safety measures. This preliminary action prevents unintentional acceleration during sudden illness while maintaining driver control authority when healthy.
Solution Approach 2:
The system requires feedback from the driver in the form of a responsiveness check before allowing override of safety interventions. This feedback mechanism ensures that the driver is conscious and in control before permitting gas pedal input to override automatic emergency braking or other safety procedures, thereby preventing unintentional acceleration during sudden illness while preserving driver authority when healthy.
Data Source
AI summary
The disclosure relates to initiating a safety procedure for decelerating a vehicle. A corresponding method can comprise obtaining, by a device comprising a processor, first data indicative of at least one driving parameter of the vehicle, obtaining, by the device, second data indicative of a driver awareness of a driver of the vehicle, initiating, by the device, a driver responsiveness check based on the first data and the second data, and initiating, by the device, the safety procedure if the driver responsiveness check is indicative of a fail of the driver responsiveness check.
