Autonomous Vehicle Parking Navigation via External Mobile Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles in parking lots face challenges in detecting mobile objects, such as children, which can lead to late or incomplete detection by environment sensors, increasing the risk of collisions.
Innovation Solution
A method and device that send position data of mobile objects within the parking lot to vehicles via a communication network, allowing for efficient and safe autonomous navigation by accounting for difficult-to-detect dynamic objects, and using a digital map with separate static and dynamic layers to optimize data transmission and reduce collision risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles navigate using only on-board environment sensors, then the vehicle can independently detect obstacles, but mobile objects such as children running between parked vehicles can only be detected with difficulty and/or late
Solution Approach 1:
The patent introduces a parking lot management system as an intermediary that uses external sensors (cameras, radar) to detect mobile objects and transmits this information to autonomous vehicles via communication networks. This mediator overcomes the limitation of on-board sensors by providing additional detection capabilities from a centralized system with broader coverage.
Solution Approach 2:
The patent combines on-board vehicle sensors with external parking lot management system sensors to create a comprehensive detection network. By merging these two detection systems, the patent achieves both independent vehicle detection and centralized monitoring, eliminating the detection gaps that exist when using only one system.
2Reliability
If the vehicle uses a comprehensive sensor system to detect all mobile objects, then detection coverage is improved, but the complexity of the vehicle's sensor system and processing requirements increases
Solution Approach 1:
The parking lot management system performs the complex detection and processing tasks centrally, serving the autonomous vehicles with processed information rather than requiring each vehicle to independently perform all detection functions. This self-service approach reduces individual vehicle complexity while maintaining comprehensive detection coverage.
Solution Approach 2:
The patent divides the detection system into two segments: on-board vehicle sensors for immediate local detection and external parking lot management sensors for comprehensive area monitoring. This segmentation allows each component to have specialized, simpler functionality while the system as a whole achieves comprehensive detection coverage.
3Reliability
If position data of mobile objects is transmitted to all vehicles in real-time, then collision risk is reduced, but data transmission volume and network bandwidth requirements increase
Solution Approach 1:
The patent transmits mobile object position data selectively to vehicles based on their specific location, trajectory, and risk level rather than broadcasting to all vehicles uniformly. This local quality approach ensures that each vehicle receives only the relevant data needed for its current situation, reducing overall network bandwidth consumption while maintaining collision risk reduction.
Solution Approach 2:
The system transmits position data with appropriate detail level based on the situation - providing full precision data only when collision risk is high, and reduced precision or aggregated data when risk is low. This partial action approach maintains safety where needed while minimizing unnecessary data transmission and bandwidth consumption.
