Integrated Vehicle Analysis System for Sudden Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for analyzing and preventing sudden vehicle acceleration lack an integrated approach, making it difficult to determine the cause of accidents and leading to disputes and increased social costs, as they do not provide a separate module for attachment/detachment via the OBD port, and information from Event Data Recorders is often inaccessible to drivers.
Innovation Solution
An integrated analysis system that combines image data from cameras and sensor measurements, including accelerator and brake pedal positions, and decibel values to determine the cause of sudden acceleration, allowing drivers to visualize and understand the vehicle control state through an intuitive interface on a mobile terminal or internet, using a data collector, integrator, determiner, and display module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing analysis systems for sudden acceleration are integrated into vehicle modules, then the system complexity increases and attachment/detachment via OBD port becomes difficult, but if they remain separate, then the system cannot provide comprehensive integrated analysis of image and sensor data
Solution Approach 1:
The system is divided into independent functional modules: image acquisition module, sensor data acquisition module, data integration module, and determination module. Each module operates independently but contributes to the overall analysis, allowing the system to maintain measurement precision while managing complexity through modular design.
Solution Approach 2:
The system integrates multiple functions into a unified platform that can analyze both image data and sensor data simultaneously. The data integration module serves as a universal interface that processes various types of input data (images from cameras, measurements from sensors) and produces comprehensive analysis results, eliminating the need for separate dedicated systems.
2Loss of information
If Event Data Recorder information is made accessible to drivers, then driver support and transparency improve, but then system security and data protection requirements increase
Solution Approach 1:
The system provides feedback to drivers by making EDR information accessible through the mobile terminal application. Drivers can view the determined cause of sudden acceleration, image data, and sensor measurements, enabling them to understand what occurred and challenge inaccurate determinations, thus improving transparency and driver support.

AI summary
An integrated analysis system includes a data collector configured to acquire an image of an accelerator pedal and an image of a brake pedal for vehicle control and collect on-board diagnostic (OBD) data, distance measurement values obtained by measuring an extent to which the accelerator pedal and the brake pedal are applied, and a decibel value of an inside of a vehicle resulting from a sudden acceleration; a data integrator configured to perform an integration process by overlaying the measured data on the image collected by the data collector; a sudden acceleration determiner configured to determine the sudden acceleration of the vehicle by using image data integrated information integrated by the data integrator; and an image display configured to provide a driver with sudden acceleration determination information obtained from the sudden acceleration determiner, the image data integrated information, vehicle driving information using the OBD data, and emergency relief information.
