Vehicle Computer Rapid Approach Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack mechanisms to effectively identify and address rapid vehicle approaches that compromise safety and determine operator accountability, which can lead to collisions and impact insurance rates.
Innovation Solution
A system that uses vehicle computer technology to collect and analyze data on speed, distance, and other metrics to calculate closing speed and accountability factors, identifying potential incidents and reporting them through a network to a server, while providing driver scores and notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no rapid approach detection system is implemented, then vehicle operators can drive without additional monitoring equipment, but collisions may occur and operator accountability cannot be determined
Solution Approach 1:
The system uses existing vehicle computer and sensor infrastructure to perform multiple functions: collecting usage data, calculating closing speed, determining accountability factors, and generating reports. This multi-functional approach improves safety without requiring entirely new dedicated hardware systems.
Solution Approach 2:
The vehicle computer automatically collects data, performs calculations, and generates accountability reports without requiring external intervention or complex additional monitoring equipment. The system serves itself by utilizing already-present vehicle computing resources.
2Measurement precision
If closing speed calculation is implemented, then rapid approach incidents can be identified, but additional data collection and processing requirements arise
Solution Approach 1:
The system leverages existing vehicle sensors and computing resources to perform closing speed calculations, rather than requiring dedicated measurement equipment. This approach achieves precise measurement without proportionally increasing system complexity.
Solution Approach 2:
The vehicle computer acts as an intermediary that processes raw sensor data and transforms it into meaningful closing speed measurements and accountability factors, simplifying the overall system architecture while maintaining measurement precision.
3Loss of information
If accountability factors are determined and reported, then operator accountability can be established, but network communication and reporting infrastructure is required
Solution Approach 1:
The system generates accountability reports that provide feedback about rapid approach incidents to relevant parties. This feedback mechanism ensures incident information is preserved and communicated without requiring complex continuous monitoring or intervention systems.
Solution Approach 2:
The system extracts and reports only the essential accountability information from the collected data, rather than transmitting all raw sensor data. This selective extraction reduces communication requirements while maintaining information availability.
Data Source
AI summary
A computer in a vehicle is configured to receive one or more data collector inputs, detect an object proximate to the vehicle based on the one or more inputs, determine a closure speed between the object and the vehicle, determine a change in speed of the object, compute an accountability factor; and determine whether to identify a potential incident based at least in part on the accountability factor and an incident value. The incident value is a function of at least one of the closure speed and a distance between the vehicle and the object. The accountability factor is based at least in part on the closure speed and the change in speed of the object.
