Engineering Contradiction Analysis
1Productivity
If a conventional electric power steering system is used, then basic steering assistance is provided, but efficient generation of motor control signals for driver assistance functions is lacking
Solution Approach 1:
The steering control system is divided into multiple independent modules: a receiver module for obtaining steering correction condition information, a determination module for assessing steering correction needs, a calculation module for computing angle correction values, and a signal generation module for producing motor control signals. This segmentation enables efficient signal generation while maintaining system manageability and reducing overall complexity.
2Reliability
If steering correction functions are added to provide driver assistance, then steering stability and safety are enhanced, but the system complexity increases
Solution Approach 1:
The system implements a closed-loop feedback mechanism where the receiver continuously obtains steering correction condition information (such as steering angle, vehicle speed, and lane position), the determination module assesses whether steering correction is needed based on this feedback, and the calculation module computes appropriate angle correction values. This feedback-driven approach enhances steering stability and safety while keeping the control logic systematic and manageable.
3Measurement precision
If accurate reflection of driving intention and vehicle state is implemented, then driver assistance function precision is improved, but information processing requirements increase
Solution Approach 1:
The system extracts only the essential steering correction condition information needed for accurate driving intention detection, such as steering angle, vehicle speed, and lane position data. By selectively extracting relevant information rather than processing all available vehicle data, the system achieves high measurement precision while minimizing the quantity of information that needs to be processed.
