Solution Overview
Problem
Existing vehicle systems struggle to efficiently manage energy consumption and emissions across multiple energy sources, particularly in hybrid vehicles that use both fuel and electrical energy, without exceeding emissions targets.
Innovation Solution
A controller system that receives emissions targets and outputs for various energy sources, determining optimal consumption rates for fuels and electrical energy to minimize emissions while meeting operational demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If multiple energy sources are used in hybrid vehicles, then energy consumption efficiency is improved, but emissions management becomes more complex
Solution Approach 1:
The controller segments the emissions management task by separately tracking and managing emissions from each energy source (fuel and electrical energy) independently, then combining them to evaluate against the emissions target. This allows complex multi-source emissions management to be broken down into manageable components.
Solution Approach 2:
The system implements feedback control by continuously monitoring actual emissions outputs from each energy source, comparing the combined emissions against the target, and dynamically adjusting consumption rates of fuel and electrical energy to maintain compliance. This closed-loop feedback manages complexity through automated real-time adjustments.
2Object-generated harmful factors
If emissions targets are strictly enforced, then environmental compliance is improved, but operational flexibility is reduced
Solution Approach 1:
The system dynamically adjusts the consumption rates of different energy sources based on real-time conditions including emissions targets, actual emissions outputs, and operational demands. This dynamic adaptation allows the vehicle to maintain emissions compliance while flexibly responding to changing operational requirements.
Solution Approach 2:
The controller changes operational parameters (consumption rates of fuel and electrical energy) based on the emissions target and actual emissions performance. By adjusting these parameters in real-time, the system maintains emissions compliance while preserving operational flexibility across different driving conditions.
3Power
If fuel consumption rate is increased, then power output is improved, but emissions output increases
Solution Approach 1:
The controller changes the consumption rate parameter of fuel based on the emissions target and actual emissions performance. When emissions approach the target, the controller reduces fuel consumption rate even if power demand remains high, thereby maintaining power output through electrical energy while reducing emissions.
