Shared Object Data Navigation Beyond Vehicle Sensor Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face limitations in object detection range, particularly in adverse conditions such as sharp curves or inclement weather, which can compromise navigation safety.
Innovation Solution
The system collects and shares object data between vehicles, allowing a current vehicle to utilize sensor data from other vehicles, even if they are out of sight, to enhance its detection range and navigation accuracy through real-time data exchange and cloud-based mapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles rely solely on their own sensors for object detection, then the system complexity remains manageable, but the object detection range is limited especially in adverse conditions
Solution Approach 1:
The patent merges sensor data from multiple vehicles into a unified detection system. The computing system combines object data from the current vehicle's sensors with object data received from other vehicles, creating a composite view that extends detection range beyond what any single vehicle could achieve alone.
Solution Approach 2:
The patent introduces a communication system as an intermediary that facilitates data exchange between vehicles. This mediator transmits object data between vehicles and the computing system, enabling extended detection capabilities without requiring direct physical connection or complex peer-to-peer coordination between all vehicles.
2Reliability
If vehicles exchange object data in real-time, then navigation safety improves, but the communication infrastructure and data processing requirements increase
Solution Approach 1:
The patent extracts only the essential object data (position, type, characteristics) from sensor inputs for transmission between vehicles, rather than exchanging complete raw sensor datasets. This selective extraction reduces communication bandwidth requirements and data processing loads while maintaining the safety benefits of shared awareness.
3Reliability
If the vehicle uses its own sensors alone, then the system operates independently, but the detection range is constrained by sensor capabilities and adverse conditions
Solution Approach 1:
The patent implements preliminary detection by other vehicles ahead of the current vehicle's position. Vehicles detect objects in advance and transmit this information to following vehicles, allowing downstream vehicles to anticipate hazards before they enter their own sensor ranges, particularly useful around sharp curves or in inclement weather conditions.

AI summary
A method includes: receiving, by a computing device, object data regarding a first object detected by a first vehicle, the object data including an object type and a location; storing the object data; generating, based on the object data, navigation data; and sending the navigation data to a second vehicle, the navigation data for use by the second vehicle to control navigation.
