Automatic Driving System Parking Lot Lane Direction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic driving systems for vehicles face reduced reliability in parking lots due to the absence of traffic rules and the presence of pedestrians and stationary objects, making accurate monitoring and navigation more complex compared to highways.
Innovation Solution
An automatic driving system that includes a travel direction acquirer to determine if parking lot lanes are unidirectional, allowing automatic driving only when lanes are unidirectional, thereby reducing the likelihood of collisions and the need for complex control maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic driving is allowed in parking lots without lane direction restrictions, then the versatility of the automatic driving system is improved, but the reliability of automatic driving is reduced due to increased collision risk from bidirectional traffic
Solution Approach 1:
The system applies different automatic driving policies to different spatial locations (lanes) based on their travel direction characteristics. Unidirectional lanes are identified and marked with travel direction information, allowing automatic driving to be permitted in these specific locations while maintaining higher safety standards. This local differentiation resolves the contradiction by enabling versatility in suitable areas while preserving reliability through restricted access in potentially hazardous bidirectional areas.
2Reliability
If the automatic driving system monitors all vehicles and objects in the parking lot environment, then the safety of automatic driving is improved, but the device complexity increases due to the need for complex monitoring and control mechanisms
Solution Approach 1:
The system performs preliminary identification and marking of unidirectional lanes before automatic driving commences. Travel direction information is acquired and stored in advance, allowing the automatic driving unit to make quick decisions based on pre-established lane characteristics rather than analyzing the entire environment in real-time. This preliminary action reduces the complexity of ongoing monitoring while maintaining safety through pre-validated lane selections.
3Adaptability or versatility
If the automatic driving unit performs complex control maneuvers to avoid other vehicles in bidirectional lanes, then the ability to navigate complex environments is improved, but the loss of time increases due to frequent maneuvering and monitoring
Solution Approach 1:
The system extracts and isolates unidirectional lanes from the complex parking lot environment, creating simplified navigation paths where traffic flows in a single direction. By selecting these extracted lanes, the automatic driving unit avoids the need for complex control maneuvers required in bidirectional areas. This extraction principle resolves the contradiction by removing the vehicle from complex interaction scenarios, thereby reducing time loss while maintaining navigational capability.

AI summary
An automatic driving system for an automatically driven vehicle. In the system, a travel direction acquirer is configured to acquire travel direction information that is information indicative of whether or not each of lanes in a parking lot is unidirectional. In addition, in the system, an allowance determination unit is configured to, if determining, based on the travel direction information acquired by the travel direction acquirer, that each of the lanes in the parking lot is unidirectional, allow automatic driving of the automatically driven vehicle.
