Object Detection Misuse Alerts for Work Machine Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines may misuse object detection systems by relying on automated collision avoidance features rather than actively controlling the machine to avoid obstacles, increasing the likelihood of collisions.
Innovation Solution
A system that includes a controller and output device to detect and classify collision mitigation events as misuse, determine a misuse value, and provide notifications when the misuse value exceeds a threshold, encouraging operators to actively avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If object detection systems implement automated collision avoidance features, then collision mitigation is improved, but operator active control is reduced
Solution Approach 1:
The system provides feedback to the operator through notifications that inform them when their inaction has been detected. The controller monitors operator inputs and provides feedback messages when the operator fails to respond to detected obstacles, encouraging active engagement while maintaining automated safety as a backup.
Solution Approach 2:
The system takes preliminary anti-action by providing warnings and notifications before allowing automated collision avoidance to activate. The controller detects when the operator is passively relying on the system and provides corrective notifications to prevent misuse before the automated system needs to intervene.
2Reliability
If object detection systems provide automated collision avoidance, then safety is improved, but operator engagement decreases
Solution Approach 1:
The system uses feedback to maintain operator engagement by notifying them when passive behavior is detected. The controller monitors operator responses and provides feedback messages that encourage active observation and control, preventing the loss of operator engagement while maintaining safety through automated detection.
3Reliability
If object detection systems rely on automated features, then collision prevention is improved, but operator skill degradation occurs
Solution Approach 1:
The system applies preliminary anti-action by providing warnings before automated systems take over completely. The controller detects operator passivity and provides notifications that encourage active engagement, preventing skill degradation before it occurs while maintaining collision prevention capabilities.
Solution Approach 2:
The system uses feedback to maintain operator skills by providing corrective notifications when passive behavior is detected. This feedback loop encourages operators to remain actively engaged and maintain their collision avoidance skills while the automated system provides a safety net.

AI summary
A system for preventing misuse of an object detection system of a work machine may include an output device and a controller communicatively coupled to the output device. The output device is configured to display a notification indicative of misuse of the object detection system. The controller includes a processing circuit comprising memory communicably coupled to one or more processors. The memory includes instructions thereon that, when executed by the one or more processors, cause the processing circuit to: detect a collision mitigation event of the work machine; classify the collision mitigation event as a misuse event; determine a misuse value associated with a work machine operation based on the misuse event; compare the misuse value with a misuse threshold; and, when the misuse value exceeds the misuse threshold, provide the notification indicative of misuse of the object detection system to the output device.
