Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for recreating vehicle accidents using accident data recorders are prone to inaccuracies due to manual operation, which can lead to unreliable results in determining the causes of accidents.
Innovation Solution
A system and method that utilize an accident data recorder to collect and analyze vehicle operation data, including acceleration, steering, and braking inputs, and automatically control a test vehicle similar in make and model to the crashed vehicle, to recreate the accident conditions accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual operation is used to recreate accidents based on ADR data, then the process is simple to implement, but the accuracy and reliability of accident recreation deteriorates
Solution Approach 1:
The patent replaces the manual mechanical operation system with an automated electronic control system. The automated accident recreation system uses electronic controllers to receive ADR data and automatically control the test vehicle's acceleration, steering, and braking inputs, eliminating human error and subjectivity while maintaining ease of implementation through systematic automation.
Solution Approach 2:
The system enables self-service by allowing the accident recreation process to execute automatically without continuous human intervention. The electronic controllers autonomously process ADR data and control the test vehicle based on recorded parameters, making the system self-sufficient in performing the recreation task while improving accuracy.
2Measurement precision
If automated electronic control is used to recreate accidents, then the accuracy and reliability of accident recreation improves, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing electronic controllers that perform multiple functions: they process ADR data, generate control signals, and coordinate various vehicle systems (acceleration, steering, braking) through a single integrated automated system. This multi-functionality reduces the need for separate specialized devices, thereby managing complexity while maintaining high accuracy.
Solution Approach 2:
The system introduces an intermediary processing layer between the ADR data and the test vehicle control. The electronic controllers act as mediators that translate recorded accident data into appropriate control signals, simplifying the overall system architecture by centralizing the control logic and reducing direct complexity at each control point.
Data Source
AI summary
A system and a method for recreating an operation of a crashed vehicle during and/or before the accident. An accident data recorder collects vehicle operation data related to the operation of the crashed vehicle prior to and/or during the accident. A processor may analyze the prior vehicle operation data that may include prior acceleration input data, prior braking input data, and/or prior steering input data and may output vehicle control data to at least one electronic controller based on the prior vehicle operation data. The at least one electronic controller automatically operates the test vehicle on a test surface to recreate an operation of the crashed vehicle during and/or before the accident. At least one electronic controller unit automatically and accurately recreates a response of the crashed vehicle to the prior acceleration input, the prior steering input, and the prior braking input.
