Automatic Parking Route Planning for Sensor Blind Spots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic parking systems, vehicles can create blind spots undetected by infrastructure sensors, making it difficult to generate appropriate travel routes that avoid contact with other vehicles and fixed structures.
Innovation Solution
An automatic parking system that includes infrastructure sensors, an identification unit to detect blind spots, an acquisition unit using on-board sensors to gather data, and a travel route generation unit to create routes based on both infrastructure and on-board sensor data, ensuring safe navigation within the parking lot.

Engineering Contradiction Analysis
1Area of stationary object
If infrastructure sensors are used to detect the state of the parking lot, then the overall detection coverage is improved, but blind spots are created around vehicles that cannot be detected
Solution Approach 1:
The system merges infrastructure sensor data with on-board sensor data from multiple vehicles to create a comprehensive view of the parking lot. The travel route generation unit integrates detection results from infrastructure sensors (which provide broad coverage) and on-board sensors (which fill in blind spots around vehicles), combining the strengths of both sensing systems to eliminate information loss.
Solution Approach 2:
On-board sensors act as intermediaries between infrastructure sensors and the travel route generation system. They detect states in blind spot areas that infrastructure sensors cannot detect, and transmit this information to the travel route generation unit, which uses it to calculate safe travel routes that avoid undetected obstacles.
2Device complexity
If blind spot areas are not considered, then the travel route calculation is simpler, but the safety of vehicle navigation is compromised
Solution Approach 1:
The system performs preliminary detection of blind spot areas using on-board sensors before generating the travel route. The travel route generation unit receives detection results from both infrastructure sensors and on-board sensors in advance, identifies blind spot regions, and incorporates this information into the route calculation process, ensuring safety is built into the route planning from the outset.
Solution Approach 2:
The system uses feedback from on-board sensors to continuously monitor and update the travel route. Detection results from on-board sensors provide feedback about actual conditions in blind spot areas, allowing the travel route generation unit to adjust routes in real-time to maintain safety while navigating through the parking lot.

AI summary
An automatic parking system includes an infrastructure sensor that is able to detect a state of a parking lot. A blind spot area that does not allow the state of the parking lot to be detected by the infrastructure sensor is identified in the parking lot, and the state of the parking including the blind spot area, the state of the parking lot being detected by an on-board sensor of a vehicle in the parking lot, is acquired. Based on the state of the parking lot detected by the infrastructure sensor and the state of the parking lot that includes the blind spot area and that is detected by the on-board sensor of the vehicle in the parking lot, a travel route for the vehicle traveling in the parking lot is generated.
