Work Vehicle Periphery Monitoring Alarm Range Adaptation

Solution Overview

Problem

Existing work vehicle periphery monitoring systems often output unnecessary alarms when detecting objects necessary for the vehicle's operation, as they cannot differentiate between obstacles and essential objects, leading to driver inconvenience.

Innovation Solution

A work vehicle periphery monitoring system that includes an alarm range storage unit, a work mode determination unit, and an alarm range changing unit to adjust the alarm range based on the vehicle's specific work mode, ensuring only necessary alarms are output.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the object detection device detects all objects in the periphery of the work vehicle, then the driver can recognize obstacles present in the periphery, but unnecessary alarms are output when objects necessary for work are detected

Engineering Contradiction:

Improvealarm accuracyVSAvoiddriver convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The alarm range is dynamically changed based on the work mode of the work vehicle. The alarm range changing unit adjusts the alarm range according to the determined work mode, making the alarm system adaptive to different working conditions and preventing unnecessary alarms while maintaining safety.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The alarm range parameter is changed according to the work mode. By changing the alarm range parameter based on different work modes (such as attachment work mode), the system distinguishes between necessary objects and obstacles, thereby improving alarm accuracy and reducing unnecessary alarms.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If the alarm range is fixed in the detection range, then the system structure is simple, but the alarm range cannot be changed according to the working state, leading to insufficient suppression of unnecessary alarms

AI summary

A work vehicle periphery monitoring system includes: an alarm range storage unit that stores an alarm range, in which an alarm output is required when an object is present, in a detection range of an object detection device that detects an object present in a periphery of a work vehicle; a work mode determination unit that determines a work mode of the work vehicle; an alarm range changing unit that changes the alarm range in the detection range when it is determined that the work mode is a specific work mode; and an alarm control unit that causes an alarm device to output an alarm when an object is present in the alarm range.
