Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the door is opened immediately when the vehicle stops, then passenger boarding efficiency is improved, but the risk of collision with approaching entities increases
Solution Approach 1:
The system performs preliminary detection of entities around the vehicle and predicts their trajectories before the door opening operation. The processor analyzes sensing information from multiple sensors to identify pedestrians, vehicles, and other obstacles in the vicinity, and predicts whether they will collide with the opening door or passengers, allowing the door control decision to be made safely and efficiently
Solution Approach 2:
The system continuously monitors the environment around the vehicle using multiple sensors (cameras, LIDAR, ultrasonic sensors) and provides real-time feedback to the door control system. The processor receives sensing information, updates entity positions and trajectories, and adjusts door opening decisions based on current environmental conditions, ensuring both safety and efficiency
2Object-affected harmful factors
If the door operation is delayed to ensure safety, then collision risk is reduced, but boarding and alighting time increases
Solution Approach 1:
The system performs preliminary detection and prediction of entity trajectories before the door opening operation. By analyzing sensing information in advance and predicting whether entities will collide with the opening door, the system can make rapid door control decisions without unnecessary delays, balancing safety with efficient boarding and alighting operations
Solution Approach 2:
The door control system dynamically adjusts its operation based on real-time environmental conditions. The processor continuously evaluates sensing information and entity trajectories, and adapts the door opening timing and speed accordingly. When the environment is safe, the door opens quickly; when entities are detected as potential threats, the door operation is delayed or modified, optimizing both safety and efficiency
3Measurement precision
If multiple sensors and cameras are used to detect entities, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The sensing system is divided into multiple independent sensor modules (cameras, LIDAR, ultrasonic sensors, radar) that can be independently configured and calibrated. Each sensor type detects specific aspects of the environment (visual information, distance, velocity), and the processor integrates these segmented data streams to achieve comprehensive and accurate entity detection with reduced individual sensor complexity
Solution Approach 2:
The system merges data from multiple different sensor types and cameras into a unified environmental model. The processor integrates sensing information from various sources to create a comprehensive understanding of entities around the vehicle, achieving high detection accuracy through data fusion while managing system complexity through centralized processing

AI summary
Disclosed is an autonomous vehicle control apparatus including a sensor that obtains sensing information associated with an entity around a vehicle, a camera that obtains an image of the entity, and one or more processor that determine whether the entity is estimated to reach the vehicle at least a predetermined time after a door of the vehicle opens, and control a position of the door.
