In-Vehicle Health Data Extraction for Remote Driver Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information provision systems for vehicle drivers primarily focus on providing driving guidance based on estimated emotion, driving skill, and physical condition, but they do not effectively utilize or transmit information necessary for grasping the driver's health condition externally, limiting the ability to improve driver health.
Innovation Solution
An information provision system that includes a driver information detection device, a communication device, and an information generation unit to extract and transmit health-related information from biological data to a user terminal outside the vehicle, enabling bidirectional communication and remote health monitoring or diagnosis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all driver biological information is transmitted to external terminals, then complete health monitoring is achieved, but data transmission volume and processing complexity increase significantly
Solution Approach 1:
The patent extracts only the necessary health-related information from the complete driver biological information dataset. The information generation unit selectively extracts vital signs and health indicators that are essential for health monitoring, excluding redundant data such as detailed driving behavior information. This extraction approach maintains health monitoring completeness while significantly reducing the volume of data that needs to be transmitted to external terminals.
Solution Approach 2:
The patent segments the driver information into different categories: health-related information (vital signs, physiological states) and non-health information (driving operations, vehicle status). By segmenting the data, the system transmits only the health-related segments to external terminals for health monitoring purposes, while retaining other segments for driving assistance functions. This segmentation resolves the contradiction by separating necessary health data from unnecessary data for health monitoring.
2Adaptability or versatility
If health-related information is extracted and transmitted externally, then remote health monitoring capability is improved, but system complexity increases
Solution Approach 1:
The information generation unit is designed with multi-functionality, serving dual purposes: it processes driver information for both driving assistance applications and health monitoring applications. The same processing unit that analyzes driving behavior also extracts health indicators, eliminating the need for separate dedicated health monitoring hardware. This multi-functionality approach enables remote health monitoring capability while avoiding significant increases in system complexity.
Solution Approach 2:
The patent introduces an information generation unit as an intermediary component between the driver information detection device and external terminals. This intermediary performs the function of selecting, processing, and formatting health-related information before transmission. By placing this intermediary layer, the system achieves remote health monitoring capability without requiring complex direct connections between all detection devices and external terminals, thus managing system complexity effectively.
3Measurement precision
If comprehensive driver information is collected, then health assessment accuracy is improved, but information processing time increases
Solution Approach 1:
The information generation unit performs preliminary processing of driver information during the driving phase itself. Vital signs and health indicators are identified, extracted, and prepared for transmission in real-time or near real-time during driving operations. This preliminary action ensures that health assessment data is ready when needed, maintaining health assessment accuracy while minimizing additional processing time required after driving concludes.
Data Source
AI summary
An information provision system is configured to detect driver information, which is information including biological information of a driver, transmit information acquired inside the vehicle to a user terminal provided outside the vehicle, acquire the driver information, extract information necessary for grasping health condition of the driver from the driver information to generate health-related information, and transmit the health-related information to the user terminal.
