Solution Overview
Problem
Agricultural work machines with a classic machine architecture face challenges in reliably detecting objects in their environment during autonomous operation, due to movements and vibrations that cause relative movements between the chassis and cabin, complicating sensor data evaluation.
Innovation Solution
The agricultural work machine is equipped with a sensor system where all sensors are either arranged on the chassis or the cabin, ensuring minimal relative movements and identical movements during operation. This setup includes multiple sensors arranged at the same height, with identical angles of inclination and fields of vision, and utilizes radar, lidar, and camera technologies to provide comprehensive object detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are distributed on both chassis and cabin, then comprehensive object detection coverage is achieved, but relative movements between chassis and cabin complicate sensor data evaluation
Solution Approach 1:
The sensor system is segmented into two independent subsystems: one mounted on the chassis and another on the cabin. Each subsystem operates independently with its own coordinate system, avoiding the complexity of evaluating combined sensor data from moving platforms. This segmentation resolves the contradiction by maintaining comprehensive detection coverage while simplifying data processing through independent evaluation of each subsystem's data.
2Reliability
If sensors are mounted on moving parts, then comprehensive environmental monitoring is achieved, but vibrations and movements create challenges for reliable object detection
Solution Approach 1:
The patent applies beforehand cushioning by using damping elements to mount the sensor systems on both the chassis and cabin. These damping elements compensate for vibrations and movements before they affect the sensors, ensuring stable sensor operation despite the dynamic environment. This resolves the contradiction by protecting the sensors from harmful vibrations while maintaining their positions on moving parts for comprehensive monitoring.
