Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated vehicle passage area is prepared for the autonomous driving vehicle, then traveling safety is improved, but facility conditions requirements increase and operational flexibility deteriorates
Solution Approach 1:
The patent implements dynamic passage space determination by continuously tracking moving objects and adjusting the restricted passage space in real-time based on current positions and motion trajectories. Instead of a fixed dedicated passage area, the system dynamically defines safe zones around moving objects, allowing flexible adaptation to changing environmental conditions while maintaining safety.
Solution Approach 2:
The control center serves as an intermediary that coordinates between autonomous driving vehicles and non-autonomous moving objects. It receives state information from all moving objects, determines appropriate passage spaces, and issues control instructions to vehicles, enabling safe operation without requiring dedicated physical passage areas.
2Difficulty of detecting and measuring
If a laser radar is installed to detect obstacles and provide information to the autonomous driving vehicle, then obstacle detection capability is improved, but system cost increases significantly
Solution Approach 1:
The control center acts as an intermediary that centralizes the obstacle detection and state information processing functions. Instead of equipping each autonomous vehicle with expensive laser radars, the control center receives state information from moving objects and processes obstacle detection centrally, then provides control instructions to vehicles, significantly reducing per-vehicle system cost.
Solution Approach 2:
The system uses state information (position, motion direction, motion speed) as a digital copy of the physical environment to determine passage spaces and control vehicle behavior. This information-based approach replaces the need for expensive physical sensing equipment like laser radars on each vehicle.
3Reliability
If separate operation of autonomous driving vehicles, non-autonomous vehicles, and pedestrians is implemented, then traveling safety is improved, but facility conditions requirements and operational complexity increase
Solution Approach 1:
The patent merges the operation management of autonomous vehicles, non-autonomous vehicles, and pedestrians under a single control center that handles all moving objects uniformly. The control center receives state information from all types of moving objects, determines passage spaces considering all entities, and coordinates their operations together, reducing operational complexity while maintaining safety through centralized coordination.

AI summary
The present invention provides a method, an apparatus, an electronic device, and a computer-readable storage medium for controlling an autonomous driving vehicle in a restricted area for a control center to adjust traveling of the autonomous driving vehicle. The method includes acquiring state information of a moving object in the restricted area, the moving object including a non-autonomous moving object and an autonomous driving vehicle, the non-autonomous moving object including a pedestrian and/or a non-autonomous driving vehicle, the state information including motion information and position information, the motion information including a motion direction and a motion speed; determining, based on state information of each of the moving objects, a temporary restricted passage space corresponding to the each moving object; and adjusting, based on state information of a current autonomous driving vehicle and a temporary restricted passage space corresponding to each of all other moving objects, traveling of the current autonomous driving vehicle. The method does not require installation of a dedicated vehicle passage area, can ensure safe operation of an autonomous driving vehicle in the entire restricted area, and is inexpensive.
