Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wheel speed sensors and inertial sensors are integrated in the same control unit, then signal processing is simplified, but synchronization errors occur between wheel speed information and sensor data
Solution Approach 1:
The control system is divided into separate control units: one dedicated to wheel speed sensors and another to inertial sensors. This segmentation allows each unit to process its specific sensor data independently, eliminating synchronization errors while maintaining manageable complexity through modular architecture.
2Device complexity
If the brake controller is integrated with the chassis base module, then system integration is improved, but adaptability to different brake control functions is reduced
Solution Approach 1:
The brake controller is separated from the chassis base module into an independent control unit. This segmentation enables the brake controller to be independently configured and adapted for different brake control functions (ESC, adaptive brake control, etc.) without being constrained by the chassis base module's fixed architecture.
Solution Approach 2:
The separated brake controller is designed as a universal control unit capable of performing multiple brake control functions. It can be configured through software to implement different control strategies (ESC, adaptive brake control, etc.), providing versatility without requiring hardware changes or integration with specific chassis modules.
3Adaptability or versatility
If a modular system with separate control units is used, then adaptability to different control functions is improved, but system complexity increases
Solution Approach 1:
The modular control units are designed with universal interfaces and standardized communication protocols. Each control unit can be configured through software to perform different control functions, allowing the system to adapt to various requirements without increasing physical complexity or requiring custom hardware for each function.
