Intersection Street Sensor Data Sharing for Autonomous Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensing systems for autonomous vehicles are limited in detecting objects at traffic intersections due to environmental configurations and lack integration with street sensors, resulting in incomplete data sharing for traffic and safety information.
Innovation Solution
An environmental safety system comprising sensors at traffic intersections that collect and process data on object parameters, generating information objects for communication networks to enhance vehicle navigation and safety information sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vehicle sensors are used for autonomous navigation, then the vehicle can identify objects in its surroundings, but the sensing capability is limited by the vehicle sensor's field of view and cannot detect certain objects at traffic intersections
Solution Approach 1:
The patent introduces street sensors as intermediary devices positioned at traffic intersections to detect objects that are outside the vehicle's field of view. These street sensors act as mediators between the vehicle's sensing system and the environment, providing additional detection coverage for pedestrians, cyclists, and other objects at intersection areas where vehicle sensors have limited capability.
Solution Approach 2:
The patent merges the sensing capabilities of vehicle-mounted sensors with street-mounted sensors to create a comprehensive detection system. By combining data from both sensor sources, the system achieves enhanced object detection coverage that overcomes the limitations of individual sensor systems, particularly at traffic intersections.
2Loss of information
If street sensors are deployed at traffic intersections, then comprehensive traffic and safety information can be collected, but the data sharing capability is limited without integration with vehicle sensor data
Solution Approach 1:
The patent creates a universal data sharing platform that serves multiple functions: collecting data from street sensors, receiving data from vehicle sensors, integrating information from both sources, and distributing comprehensive traffic information to authorized receivers. This multi-functional system eliminates information loss by ensuring complete data exchange between street and vehicle sensors.
Solution Approach 2:
The patent implements a feedback mechanism where street sensors and vehicle sensors continuously exchange data through a communication network. The system receives sensor data, processes and integrates it, then feeds back comprehensive traffic information to both street and vehicle systems, creating a closed-loop information sharing ecosystem that reduces data loss.
3Measurement precision
If vehicle sensors operate independently, then the vehicle can make navigation decisions, but the navigation accuracy is limited without integrated street sensor data
Solution Approach 1:
The patent implements preliminary action by having street sensors detect and report objects at traffic intersections before vehicles arrive. This advance detection allows the vehicle's navigation system to receive pre-processed safety information about pedestrians, cyclists, and other hazards, enabling more accurate navigation decisions and reducing information loss about potential dangers.

AI summary
An environmental safety system may comprise a plurality of first sensors each located at a predetermined physical location of a traffic intersection and with a predetermined orientation. The system may have a memory storing executable instructions. The system may have one or more processors in communication with the plurality of first sensors and the memory. The one or more processors may be programmed by the executable instructions. The system may receive first sensor data captured at a time point and by the plurality of first sensors. The system may determine values of one or more parameters of an object of interest within a threshold distance of the traffic intersection using the first sensor data. The system may generate an information object comprising the values of the one or more parameters of the object of interest, the time point, and a signature of the information object. The system may transmit, via a communication network, the information object.
