Engineering Contradiction Analysis
1Reliability
If conventional parking assistance apparatus is used, then the system structure is simple, but the sensing capability of access situation with surrounding objects is limited
Solution Approach 1:
The parking assistance apparatus segments the sensing function into multiple independent sensing units that can detect access distances in different directions (forward and backward). Each sensing unit operates independently to measure distance to surrounding objects, allowing the system to comprehensively monitor the vehicle environment without requiring a single complex sensing mechanism.
Solution Approach 2:
The controller integrates multiple functions including sensing data processing, electronic parking brake control, steering control, and display management. This multi-functional integration allows the system to achieve comprehensive parking assistance capabilities while managing complexity through centralized control logic that handles various parking scenarios universally.
2Reliability
If conventional parking assistance apparatus is used, then the system is easy to operate, but the ability to prevent collision with surrounding objects is insufficient
Solution Approach 1:
The system implements continuous feedback by constantly monitoring access distances through sensing units and providing real-time information to the driver via display units. The controller receives ongoing distance data, compares it against safe thresholds, and provides continuous guidance or automatic intervention, ensuring the driver remains informed of the vehicle's proximity to surrounding objects throughout the parking maneuver.
Solution Approach 2:
The electronic parking brake and electronic steering act as intermediary control mechanisms between the driver's intent and the vehicle's physical movement. These automated systems mediate the parking process by automatically adjusting brake application and steering angle based on sensed distance conditions, reducing the driver's direct operational burden while maintaining collision prevention.
3Reliability
If automated steering and brake operations are implemented, then parking safety is improved, but the control system complexity increases
Solution Approach 1:
The electronic parking brake control and electronic steering control are merged into a single integrated control system managed by one controller. This consolidation combines multiple control functions into a unified architecture, reducing the number of separate control units and interconnections needed, thereby managing system complexity while maintaining comprehensive automated control for safety.
