Innovation Solution
A hybrid drive system comprising a combustion engine, an electrical machine, and an accessory drive system, where the electrical machine is coupled to the combustion engine via a clutch, allowing for selective power supply from either source to the drive train and accessories, with the ability to start the combustion engine using the electrical machine and control power distribution based on operating conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrical machine is coupled to the combustion engine via a clutch for selective power supply, then the adaptability and flexibility of power transmission are improved, but the device complexity increases due to additional coupling mechanisms and control systems
Solution Approach 1:
The electrical machine is designed to perform multiple functions: it can operate as a motor to drive the generator when the combustion engine is running, and as a generator to recharge the battery when the combustion engine is off. This multi-functionality reduces the need for separate dedicated components for each function, thereby improving adaptability while managing device complexity
2Ease of operation
If the electrical machine can start the combustion engine and control power distribution, then the ease of operation and control are improved, but the device complexity increases due to advanced control systems
Solution Approach 1:
The control system automatically manages power distribution between the combustion engine and electrical machine based on real-time operating conditions without requiring manual intervention. The system self-regulates by monitoring battery charge levels, engine status, and power demands, thereby improving ease of operation while keeping the control system architecture relatively simple through automated decision-making algorithms
