Solution Overview
Problem
Existing refuse collection vehicles lack efficient systems for autonomously identifying and engaging with refuse containers, leading to manual operation and reduced efficiency.
Innovation Solution
A system comprising sensors (such as visible light cameras, LiDAR sensors, and radar sensors) and processors that detect objects and positional data to identify refuse containers and adjust operating parameters of the vehicle, such as steering and braking, to autonomously approach and engage with the containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for refuse container engagement, then operational flexibility is maintained, but productivity and efficiency are reduced
Solution Approach 1:
The system enables the refuse collection vehicle to autonomously identify, locate, and engage with refuse containers using onboard sensors (cameras, LiDAR, radar) and processors. The vehicle self-adjusts operating parameters and executes engagement maneuvers without manual intervention, allowing the system to serve itself in the collection process
Solution Approach 2:
The patent replaces manual mechanical operation with an automated control system that uses sensor data processing and electronic control signals. The processors analyze sensor inputs and automatically generate control commands for vehicle movement and engagement mechanisms, substituting human-operated mechanical control with electronic automation
2Productivity
If autonomous identification system is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The system employs multiple sensor types (cameras, LiDAR, radar) that can detect various objects and environmental conditions, making them versatile for different detection scenarios. These multi-functional sensors contribute to both refuse container identification and general navigation, reducing the need for specialized single-purpose components
Solution Approach 2:
The patent combines multiple sensor systems and processing functions into an integrated autonomous control system. The processors consolidate data from various sensors and coordinate multiple vehicle functions (steering, braking, engagement), merging complex components into a unified control architecture that manages complexity through integration

Data Source
AI summary
A system for controlling the operation of a refuse collection vehicle includes at least one first sensor coupled to the vehicle to detect objects during an approach, at least one second sensor to detect the vehicle's position during the approach, and one or more processors. The processors receive object data from the first sensor and positional data from the second sensor, and use this information to identify a refuse container. Upon identifying the refuse container, the processors transmit a first instruction to the vehicle's control system to adjust operating parameters during the approach.
