Trailer Detachment Detection Using Camera Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The detachment of a trailer from a vehicle can pose a significant safety hazard, as drivers may not be aware of the detachment, especially when a safety chain or other device still connects the trailer, leading to potential accidents and damage.
Innovation Solution
A trailer monitoring system that includes a detection device, such as a camera, to generate data on the connection between the trailer coupler and hitch, and a processing device to analyze this data for partial detachment conditions, alerting the driver and controlling vehicle operations like braking and steering to mitigate hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety chain is used to connect the trailer, then the trailer remains connected after hitch detachment, but the driver may not be aware of the detachment leading to safety hazards
Solution Approach 1:
The system continuously monitors the hitch connection status using a camera and image processing, providing real-time feedback to the driver through visual alerts when detachment is detected. The processing device analyzes the position of the coupler and ball in captured images to determine connection status, creating a closed-loop monitoring system that eliminates the information asymmetry problem.
Solution Approach 2:
The camera system acts as an intermediary between the physical hitch connection and the driver's awareness. Instead of directly observing the connection, the driver receives processed visual information from the camera that indicates connection status, translating complex mechanical states into simple visual alerts.
2Loss of information
If the driver is notified of detachment, then safety awareness is improved, but response time may be delayed without automated control
Solution Approach 1:
The system performs preliminary actions by pre-programming the vehicle control responses to detachment scenarios. When detachment is detected, the control device automatically executes pre-planned maneuvers such as activating hazard lights, applying brakes, or steering to a safe position without waiting for driver reaction, significantly reducing response time.
Solution Approach 2:
The system provides self-service by autonomously managing the vehicle's safety responses to detachment events. The control device independently determines and executes appropriate corrective actions based on the detected detachment status, reducing reliance on driver reaction and enabling immediate response to the hazard.
3Object-affected harmful factors
If automated vehicle control is implemented to respond to detachment, then accident prevention is improved, but system complexity increases
Solution Approach 1:
The system achieves multi-functionality by using a single camera system for both detection and control functions. The same image processing capabilities that detect detachment also provide visual feedback to the driver, and the control device integrates multiple safety functions (braking, steering, hazard lights) into a unified response system, reducing overall complexity despite the advanced capabilities.
Data Source
AI summary
A system for monitoring a trailer includes a detection device configured to monitor a connection between a coupler attached to the trailer and a trailer hitch attached to a vehicle and generate data related to the connection, and a processing device configured to receive the data from the detection device, and analyze the data to detect whether a partial detachment condition is present. Based on detecting the partial detachment condition, the processing device is configured to generate a notification to a driver to alert the driver of the partial detachment condition and/or control operation of the vehicle.
