Object-Aware Cab Sound Control for Work Vehicle Operator Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles face challenges in maintaining awareness of their surroundings while performing tasks, as they need to balance controlling the vehicle with being aware of other vehicles, equipment, and personnel in the work area.
Innovation Solution
An object intelligence detection system that uses sensors to detect objects outside the work vehicle and generates alerts by adjusting the sound level within the operator cab, utilizing a processor and memory device to execute instructions for object detection and sound level adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator concentrates on controlling the work vehicle to perform tasks, then the productivity and task completion efficiency are improved, but the awareness of surrounding objects and personnel deteriorates
Solution Approach 1:
The patent introduces sensors (cameras, LIDAR, radar) as intermediary devices that detect objects and personnel in the work area. These sensors act as mediators between the operator and the surrounding environment, providing information about objects without requiring the operator to visually monitor the area. The system processes sensor data and presents it to the operator through displays or alerts, enabling the operator to maintain concentration on vehicle control while still being aware of the environment.
Solution Approach 2:
The patent replaces the mechanical/visual monitoring system with an automated sensor-based detection system. Instead of relying on the operator's natural senses and attention to detect objects, the system uses electronic sensors, processors, and communication devices to automatically detect, track, and communicate information about surrounding objects. This substitution allows the operator to focus on vehicle control while the automated system handles environmental awareness.
2Reliability
If the operator maintains awareness of the work area to detect objects and personnel, then the safety is improved, but the concentration on vehicle control and task performance deteriorates
Solution Approach 1:
The system uses sensors and processing devices as intermediaries to detect and monitor the work area environment. These intermediaries continuously scan for objects and personnel, filtering and processing the data to identify relevant safety information. The processed information is then presented to the operator in a concise manner (through displays, icons, or alerts), providing safety awareness without requiring the operator to divide attention significantly from vehicle control.
Solution Approach 2:
The patent implements a feedback loop where sensors continuously monitor the environment, the processor analyzes the data, and the system provides feedback to the operator through the communication device. This automated feedback mechanism maintains safety awareness by constantly updating the operator on detected objects and personnel, allowing the operator to respond to safety situations without needing to actively scan the environment, thus preserving concentration on vehicle control.
3Loss of information
If sound emission devices operate at high sound levels to alert operators, then the notification effectiveness is improved, but the distraction from vehicle operations increases
Solution Approach 1:
The patent applies different sound levels and notification intensities based on the specific situation and location. Rather than using a uniform high sound level for all notifications, the system adjusts the sound emission locally according to the detected object's proximity, type, and urgency. This allows effective notification for critical situations while using lower, less distracting sound levels for routine information, thereby maintaining ease of operation.
Solution Approach 2:
The system dynamically adjusts sound emission levels based on real-time conditions. The processor evaluates the detected objects and determines appropriate notification strategies, varying the sound level, frequency, and duration based on factors such as object distance, movement speed, and potential hazard level. This dynamic adjustment ensures that sound notifications are effective when needed while minimizing distraction during normal operations.

AI summary
An object intelligence detection system can selectively adjust the operation of one or more sound emission devices of a work vehicle to reduce a sound level within an associated operator cab. The reduction of the sound level within the operator cab can be triggered in response to different types of information, including information captured by one or more sensor systems regarding detected objects positioned outside of the work vehicle. Such captured information can also provide details used to determine whether detected object has a protected status, is performing a particular action or movement, or is located at a particular position relative to the work vehicle that qualifies for the reduction in the sound level within the operator cab. The reduction in sound level can also be triggered by the type of task being performed by the work vehicle, or the location of the work vehicle relative to a work zone.
