Vehicle Driver Risk Assessment System Using Integrated Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle monitoring systems do not provide a reliable method for assessing the accident risk of a vehicle driver, which is crucial for insurance policies, as they lack the capability to objectively evaluate driving behavior.
Innovation Solution
A system that uses an accelerometer to detect vehicle acceleration and deceleration, GPS to track position and speed, and a GSM/GPRS module to send data to an operations center for calculating a risk indicator, integrating these components into a device mounted on the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite navigators, accident detectors, and mobile telephones are used for vehicle monitoring, then vehicle position and accident detection capabilities are improved, but the ability to objectively assess driver accident risk is not achieved
Solution Approach 1:
The system integrates multiple functions into a single device: GPS satellite navigation for position tracking, accelerometer-based crash detection, GSM mobile telephone for communication, and driving behavior analysis for risk assessment. This multi-functional integration allows the device to simultaneously perform navigation, safety monitoring, and insurance-relevant risk evaluation, resolving the contradiction by making the system universally applicable to multiple needs including the previously unmet accident risk assessment function
2Measurement precision
If traditional crash sensors and GPS devices are installed in vehicles, then accident detection and position tracking are improved, but objective evaluation of driving behavior for insurance purposes is not possible
Solution Approach 1:
The patent merges previously separate functions (GPS navigation, crash detection, mobile communication) into a single integrated device. By combining these existing technologies with driving behavior analysis capabilities, the system achieves precise measurement of driving patterns without proportionally increasing complexity, as the components share common hardware resources and communication interfaces
3Loss of information
If multiple sensors and communication modules are integrated into a vehicle device, then data collection capabilities are improved, but the simplicity of the assessment system is reduced
Solution Approach 1:
The integrated device performs multiple functions using shared hardware components: the GPS module provides position data for both navigation and risk assessment, the accelerometer detects both crashes and driving behavior patterns, and the GSM module handles both emergency calls and data transmission. This multi-functionality approach collects comprehensive driving data while avoiding the complexity of separate dedicated systems for each function
