Refuse Vehicle Operational Mode Control for Route-Specific Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refuse vehicles often require multiple operational modes to efficiently perform different tasks, such as recycling and garbage collection, but existing systems lack the ability to automatically adjust performance parameters based on route types and environmental conditions.
Innovation Solution
A refuse vehicle system that includes a processing unit communicating with the motor and hydraulic system, allowing it to access and execute preset operational modes stored in memory. These modes adjust performance parameters based on selected route types and environmental conditions, optimizing vehicle performance for specific tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operational modes are provided for different tasks, then adaptability is improved, but device complexity increases
Solution Approach 1:
The control system is designed to perform multiple functions by implementing a universal architecture that can execute different operational modes (recycling, garbage collection, haul routes) through a single integrated processing unit that adjusts performance parameters based on selected route types
Solution Approach 2:
The system resolves complexity by dynamically changing performance parameters (motor power, hydraulic flow, transmission ratios) based on the selected operational mode, allowing the same hardware to adapt to different tasks without requiring separate specialized systems for each function
2Productivity
If performance parameters are automatically adjusted, then productivity is improved, but device complexity increases
Solution Approach 1:
The control system automatically adjusts performance parameters without requiring manual intervention, with the processing unit independently selecting and implementing appropriate motor power, hydraulic flow, and transmission settings based on the selected operational mode and detected conditions
Solution Approach 2:
The system incorporates sensors that detect environmental conditions (temperature, humidity, route characteristics) and feed this information back to the processing unit, which then automatically adjusts performance parameters to optimize vehicle operation for the specific conditions

AI summary
A refuse vehicle has a chassis supporting a plurality of wheels, as well as a motor. A vehicle body is also supported by the chassis and defines a receptacle for storing refuse. A lifting system is coupled to the vehicle body and is movable between a first position and a second position different from the first position. The refuse vehicle also has a processing unit in communication with the lifting system and the motor. The processing unit is configured to access and execute a plurality of preset operational modes stored within a memory to adjust performance parameters of the refuse vehicle. The operational modes include at least two different operational modes corresponding to a presence or an absence of a first attachment in communication with the processing unit.
