Driver Assistance Device Integrating External Sleep Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems fail to account for a driver's condition outside or inside the vehicle, such as drowsiness, when determining the level of risky driving, which can lead to increased insurance premiums without recognizing the driver's impaired state in a timely manner.
Innovation Solution
A driver assistance device that acquires both external life condition information, like sleep efficiency, and internal driving situation information, such as arousal level, to generate warnings about potential insurance premium increases and transmit relevant data to an external server based on driver acceptance or rejection of the warning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the level of risky driving is determined based only on driving behavior, then the determination process is simple, but the accuracy of risk assessment deteriorates because driver conditions outside or inside the vehicle are not considered
Solution Approach 1:
The patent combines multiple information sources including first information from outside the vehicle (sleep efficiency, daily routine) and second information from inside the vehicle (arousal level, driving behavior) to comprehensively determine driver condition and risk level, thereby improving assessment accuracy while managing system complexity through integrated processing
2Reliability
If warning information about insurance premium increase is provided to the driver, then driver awareness of risk is improved, but driver acceptance may deteriorate due to financial concern
Solution Approach 1:
The system provides feedback to the driver in the form of warning information about potential insurance premium increases based on detected driver condition, allowing the driver to understand the risk and take corrective action, while the reception unit captures driver response to adjust subsequent communications
3Loss of time
If the driver's condition is monitored continuously both outside and inside the vehicle, then early recognition of impaired state is improved, but energy consumption increases
Solution Approach 1:
The system performs preliminary monitoring of driver condition outside the vehicle (sleep efficiency, daily routine) before driving begins, and continues monitoring inside the vehicle during driving, enabling early recognition of impaired states while managing energy consumption through strategic placement of sensors and selective monitoring
Data Source
AI summary
An acquisition unit acquires at least one of first information and second information. A notification unit provides warning information to the driver, the warning information being generated based on at least one of the first information and the second information acquired and indicating a possibility of an increase in an insurance premium of an insurance applied to the driver. An reception unit receives acceptance of the provided warning information from the driver. A processor determines to transmit the acceptance by the driver of the possibility of an increase in the insurance premium to an insurance company server when the acceptance is received and determines to transmit at least one of the first information and the second information to the insurance company server when acceptance is not received.
