Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicles face challenges in detecting and responding to drowsy or inattentive drivers, leading to increased risks of accidents due to delayed reaction times and decreased alertness.
Innovation Solution
A system and method that utilize multiple vehicle systems to detect driver drowsiness through various sensors and modify the operation of systems like power steering, climate control, and alert systems to enhance driver alertness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single vehicle system is used to detect hazards and respond to driver behavior, then the system operation is simple, but the response effectiveness and reliability are insufficient
Solution Approach 1:
The patent combines multiple vehicle systems (first vehicle system and second vehicle system) to work together in detecting hazards and monitoring driver drowsiness. By merging the functions of multiple systems, the patent achieves improved reliability and response effectiveness while distributing the computational and detection workload across different system components.
Solution Approach 2:
The patent divides the hazard detection and driver monitoring function into separate vehicle systems. The first vehicle system handles primary hazard detection, while the second vehicle system handles driver behavior monitoring and drowsiness detection. This segmentation allows each system to specialize in specific tasks, improving overall reliability without requiring one system to handle all functions.
2Reliability
If driver drowsiness is monitored and vehicle systems are modified to compensate, then driver safety is improved, but the control complexity of vehicle systems increases
Solution Approach 1:
The patent implements a feedback mechanism where the vehicle systems continuously monitor driver drowsiness levels and automatically adjust their operation in response. The system detects driver behavior indicators (eye closure, head position, steering patterns) and feeds this information back to modify system control parameters, creating a closed-loop control system that adapts to driver state without requiring complex manual intervention.
Solution Approach 2:
The patent makes the vehicle system control dynamic by allowing it to adapt its operation based on real-time driver drowsiness detection. Instead of fixed control parameters, the system dynamically adjusts its behavior (such as modifying steering assistance, alerting mechanisms, or hazard response thresholds) based on the detected driver state, enabling flexible adaptation without permanent system modifications.
3Reliability
If multiple vehicle systems are used to detect driver drowsiness and modify operations, then the reliability and response effectiveness are improved, but the device complexity increases
Solution Approach 1:
The patent designs the vehicle systems to perform multiple functions: the first vehicle system detects hazards and monitors basic driver behavior, while the second vehicle system detects driver drowsiness and coordinates with the first system. By making these systems multi-functional, the patent reduces the need for entirely separate dedicated systems, thereby improving reliability through functional redundancy while limiting the increase in overall system complexity.

AI summary
Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a slow reaction time, attention lapse and/or alertness of a driver. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The response system can modify the control of two or more systems simultaneously in response to driver behavior.
