Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate algorithms are used to determine steering angle, acceleration, and braking independently, then comprehensive vehicle control is achieved, but computational complexity and processing time increase
Solution Approach 1:
The patent combines multiple separate algorithms (steering angle determination, acceleration determination, braking determination) into a single integrated algorithm that processes track geometry data and vehicle state simultaneously to generate all control commands. This merging reduces computational overhead and processing time while maintaining comprehensive vehicle control along the predefined track.
2Use of energy by moving object
If real-time adjustment of vehicle parameters is implemented, then energy efficiency is improved, but system complexity and response time requirements increase
Solution Approach 1:
The system pre-calculates optimal vehicle parameters (speed, acceleration, steering angle) based on track geometry data before vehicle arrival at specific track sections. This preliminary determination allows real-time energy-efficient operation without requiring complex real-time adjustments, as the optimal parameters are predetermined and simply executed during vehicle operation.
Solution Approach 2:
The algorithm dynamically adjusts vehicle parameters (speed, acceleration, steering) based on real-time vehicle state and upcoming track geometry, optimizing energy consumption throughout the journey. The system continuously adapts control commands to match actual vehicle conditions while maintaining energy efficiency.
3Manufacturing precision
If detailed track geometry data is processed, then route accuracy and vehicle control precision are improved, but data processing time and computational resources increase
Solution Approach 1:
The system processes and stores detailed track geometry data (curves, gradients, intersections) in advance before vehicle operation. This pre-processing creates a ready-to-use reference database that enables rapid real-time control decisions without requiring intensive processing during actual vehicle operation, thus maintaining high route accuracy while minimizing processing time.
