Mobile Accelerometer Crash Detection for Timely Vehicle Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems delay the reporting of vehicle crashes, often resulting in incomplete or vague insurance claims due to delayed and inaccurate driver reports.
Innovation Solution
A mobile computing device equipped with an accelerometer, communication circuitry, and processor analyzes acceleration measurements to detect crashes, corroborates with sensor data, and transmits relevant information to a server for timely insurance processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If driver reports crashes manually after the incident, then the reporting process is simple and requires minimal technology, but the reporting is delayed and information becomes incomplete or vague
Solution Approach 1:
The system performs preliminary actions by continuously monitoring acceleration data and automatically detecting crashes before any reporting is needed. The accelerometer constantly measures acceleration, and the processor automatically identifies crash events by comparing measurements against threshold values, eliminating the need for delayed manual reporting.
Solution Approach 2:
The system serves itself by automatically detecting crashes through sensor data and generating reports without human intervention. The mobile device autonomously monitors its own crash status through the accelerometer and communication circuitry, and automatically transmits crash data to the server, removing the dependency on driver action.
2Reliability
If manual crash reporting is used, then the system complexity is low, but the information completeness and reliability of claims are poor
Solution Approach 1:
The patent replaces the mechanical/manual reporting system with an automated electronic detection and communication system. The accelerometer electronically senses crash forces, the processor automatically analyzes the data, and communication circuitry electronically transmits the crash information to the server, eliminating the need for manual driver reporting.
Solution Approach 2:
The mobile device performs multiple functions: it serves as an accelerometer for crash detection, a processor for data analysis, a communication device for transmitting crash data, and a location tracker for determining crash position. This multi-functionality within a single device reduces overall system complexity while improving reliability.

Data Source
AI summary
Systems and methods are disclosed for determining whether or not a crash involving a vehicle has occurred. A computing device may receive acceleration measurement(s) measured by one or more accelerometers during a time window. The computing device may determine, for one or more acceleration measurements, a corresponding acceleration magnitude. Based on the corresponding acceleration magnitude(s), the computing device may identify, from the acceleration measurement(s), an acceleration measurement and/or may determine whether the acceleration magnitude exceeds a threshold acceleration magnitude. The computing device may corroborate whether a vehicle associated with the mobile computing device was involved in a crash. Data associated with the acceleration magnitude and/or an event, such as a crash event, may be transmitted to a server.
