Driver Heartbeat Monitoring for Vehicle Assist Intervention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack effective solutions to monitor and address a driver's health status, such as fatigue or inattention, while driving, which can lead to safety risks for the driver, occupants, and others on the road.
Innovation Solution
A vehicle-based driver health monitoring system that uses a heartbeat sensor to capture biological data, processes it with an electronic control unit, and takes appropriate actions based on comparisons with stored nominal health data, including alerts, vehicle control interventions, and emergency notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heartbeat sensor is used to monitor driver health status, then driver safety is improved, but device complexity increases
Solution Approach 1:
The ECU is designed to perform multiple functions: it processes heartbeat sensor data for health monitoring, retrieves driver profiles from memory, compares measured aspects with nominal values, and controls vehicle functions. This multi-functionality consolidates what could be separate systems into a single control unit, improving reliability while managing complexity.
Solution Approach 2:
The system introduces an intermediary processing layer between the heartbeat sensor and vehicle control functions. The ECU acts as a mediator that receives sensor data, processes it through profile comparison, and then triggers appropriate vehicle responses. This intermediary structure improves safety through systematic processing while organizing system complexity into manageable stages.
2Reliability
If driver health monitoring is implemented, then accident prevention is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs self-service by automatically monitoring driver health status without requiring driver intervention. The heartbeat sensor continuously captures data, the ECU automatically processes and compares it with stored profiles, and the system autonomously determines when health aspects are abnormal. This eliminates the need for driver action while improving accident prevention.
Solution Approach 2:
The system implements feedback by continuously monitoring driver health status and using this information to automatically adjust or control vehicle functions. The closed-loop feedback mechanism ensures driver safety through continuous monitoring and automatic response, without burdening the driver with manual health assessments or controls.
3Measurement precision
If continuous heartbeat monitoring is performed, then driver health detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic action by retrieving driver profiles from memory at scheduled intervals rather than continuously. The ECU periodically accesses stored nominal health data to compare with current heartbeat measurements, maintaining measurement precision while reducing the energy consumption associated with continuous memory access and data processing operations.

AI summary
A vehicular occupant health monitoring system includes a heartbeat sensor disposed at a vehicle and operable to capture sensor data measuring an aspect associated with the heart of an occupant of the vehicle. A control includes a processor operable to process sensor data captured by the heartbeat sensor and provided to the control. The vehicular occupant health monitoring system, responsive to processing by the processor of sensor data captured by the heartbeat sensor, determines whether the measured aspect associated with the heart of the occupant is abnormal. The vehicular occupant health monitoring system, responsive to determining the measured aspect associated with the heart of the occupant is abnormal, controls a function of the vehicle.
