Inter-Vehicle Sensor Sharing for Autonomous Navigation Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of autonomous vehicles on the road leads to inefficient use of computing resources due to redundant data collections and computations, as each vehicle operates independently with its own sensor systems, leading to exponential computational complexity.
Innovation Solution
Autonomous vehicles share data collected by their sensor systems with other vehicles through direct or indirect communication, reducing the need for redundant computations by adjusting sampling rates and operational parameters based on shared information.

Engineering Contradiction Analysis
1Reliability
If each autonomous vehicle operates independently with its own sensor systems, then each vehicle can autonomously detect and respond to its environment, but the computational complexity increases exponentially due to redundant data collections and computations across multiple vehicles
Solution Approach 1:
The patent merges sensor systems and computing resources across multiple autonomous vehicles into a shared network. Vehicles exchange sensor data and computational tasks through communication interfaces, allowing the fleet to function as a distributed sensing and computing system rather than isolated units, thereby reducing redundant computations while maintaining autonomous navigation capabilities
Solution Approach 2:
The patent implements universal data formats and communication protocols that enable sensor data from different vehicle types and sensor systems to be processed interchangeably. This multi-functionality allows any vehicle's sensor data to contribute to the navigation decisions of any other vehicle, reducing the need for each vehicle to independently process all environmental data
2Ease of operation
If each autonomous vehicle uses its own sensor systems for environment detection, then each vehicle has complete control over its sensing operations, but computing resources are wasted due to redundant data collection across the fleet
Solution Approach 1:
The patent enables vehicles to selectively share their sensor data with other vehicles that would benefit from it, creating a self-service system where each vehicle contributes resources it has in excess and consumes resources it needs. This maintains operational independence while reducing overall fleet computational waste through peer-to-peer resource sharing
Solution Approach 2:
The patent implements dynamic adjustment of data sharing and sampling rates based on real-time conditions. Vehicles adjust their sensor collection frequency and sharing behavior according to environmental factors, traffic conditions, and the informational needs of neighboring vehicles, optimizing the balance between independent operation and resource efficiency
