Infrastructure Road User Detection for Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack comprehensive real-time data about road users and infrastructure within their vicinity, particularly in construction zones, which can lead to navigation challenges and safety concerns due to limited sensing capabilities and processing power.
Innovation Solution
An infrastructure device mounted near roads establishes secure communication with autonomous vehicles, providing data sets including coordinate, classification, and behavioral models of road users, and temporary lane boundaries, enhancing the vehicle's perception and navigation through sensor data and wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If autonomous vehicles rely solely on their own sensors and processing power, then device complexity is reduced, but sensing range and situational awareness deteriorate
Solution Approach 1:
The infrastructure device acts as an intermediary between remote service providers and autonomous vehicles. It receives sensor data from multiple sources, processes it centrally, and transmits processed road user information to vehicles within its communication range. This mediator approach extends the effective sensing range of individual vehicles without requiring each vehicle to independently manage complex multi-source sensor integration.
2Reliability
If autonomous vehicles process all sensor data locally, then reliability is improved, but processing power requirements and energy consumption worsen
Solution Approach 1:
The system segments the data processing function across multiple entities: infrastructure devices perform initial data collection and processing, filtering raw sensor data into structured road user information. Autonomous vehicles then receive only the processed, relevant data for their specific context. This segmentation reduces the computational burden and energy consumption on vehicles while maintaining data accuracy through distributed processing.
3Loss of information
If infrastructure devices transmit detailed road user data to all vehicles, then situational awareness is improved, but communication bandwidth requirements and data transmission energy worsen
Solution Approach 1:
The infrastructure device provides different levels of data detail to different vehicles based on their specific needs, locations, and contexts. Each vehicle receives road user information tailored to its operational context rather than a uniform comprehensive data set. This local quality approach ensures information completeness for each vehicle's situation while reducing overall communication bandwidth requirements and transmission energy consumption.
Data Source
AI summary
A method and device are disclosed that establish secure electronic communication between an infrastructure device and a remote provider of services to an autonomous vehicle. In response to the autonomous vehicle driving within a predetermined distance of the infrastructure device, the remote provider sends authorizing credentials to the infrastructure device and the autonomous vehicle. Using the authorizing credentials, the infrastructure device and the autonomous vehicle establishing a trusted communication. Through the trusted communication, the infrastructure device sends to the autonomous vehicle a data set including coordinate data of at least one road user.
