Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the autonomous driving control apparatus provides basic function information to the user, then the user receives operational status updates, but the user cannot directly know performance changes when events occur
Solution Approach 1:
The patent implements a feedback mechanism where the autonomous driving control apparatus continuously monitors its own performance metrics (sensor performance, driving performance, control performance) and provides this information back to the user through the notification device. This resolves the information loss by ensuring performance data is communicated to the user without requiring complex manual analysis systems.
Solution Approach 2:
The notification device serves as an intermediary between the autonomous driving control apparatus and the user. It translates complex performance data into user-friendly notifications, reducing the information processing complexity while maintaining complete performance information transmission.
2Reliability
If the autonomous driving control apparatus monitors sensor operation states and driving information to identify performance deterioration, then the system reliability improves, but the device complexity increases
Solution Approach 1:
The controller performs multiple functions: it controls autonomous driving operations, monitors sensor operation states, analyzes driving information, identifies performance deterioration, and triggers parameter adjustments. By consolidating these functions in a single control unit, the system achieves high reliability without proportionally increasing overall device complexity.
Solution Approach 2:
The autonomous driving control apparatus monitors itself for performance deterioration and automatically adjusts its own parameters without external intervention. This self-service capability enhances reliability by enabling real-time self-correction while minimizing the need for additional external monitoring systems.
3Adaptability or versatility
If the autonomous driving control apparatus changes control parameters in real-time to maintain performance, then the system adaptability improves, but the control complexity increases
Solution Approach 1:
The system dynamically adjusts control parameters based on real-time sensor operation states and driving conditions. The controller modifies sensor parameters, deceleration/acceleration parameters, and other control variables adaptively, enabling the system to respond to changing conditions without requiring complex manual reconfiguration.
Solution Approach 2:
The patent implements parameter changes as the core mechanism for maintaining performance. When deterioration is detected, the controller changes specific parameters (sensor parameters, deceleration/acceleration parameters) to restore optimal functioning. This approach provides adaptability through systematic parameter adjustment rather than complex structural modifications.
4Loss of information
If the autonomous driving control apparatus provides detailed performance information to the user, then the user confidence increases, but the information transmission complexity increases
Solution Approach 1:
The notification device acts as an intermediary that receives comprehensive performance data from the controller and presents it to the user in an accessible format. This intermediary layer ensures complete information transmission while simplifying the user interface and reducing notification system complexity.
Solution Approach 2:
The system implements structured feedback loops where performance information flows from the controller to the notification device and then to the user. This organized feedback mechanism ensures complete information delivery without requiring complex ad-hoc communication systems.

AI summary
An autonomous driving control apparatus includes a sensor device, a notification device, a memory, and a controller. In particular, the autonomous driving control apparatus identifies whether an autonomous driving control function for a host vehicle deteriorates, based on at least one of an operation state of the sensor device, driving information of the host vehicle, or any combination thereof. The autonomous driving control apparatus changes an autonomous driving control parameter including at least one of a sensor parameter, a deceleration and acceleration parameter, or any combination, when it is identified that the autonomous driving control function deteriorates. The autonomous driving control apparatus outputs at least one of the operation state of the sensor device, the driving information of the host vehicle, whether the autonomous driving control function deteriorates, whether autonomous driving control parameter changes, or any combination thereof, using the notification device.
