Distributed ADS Feature Verification Across ODD-Specific Vehicle Fleets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The verification process for Autonomous Driving Systems (ADS) is complex and costly, relying heavily on customer fleets and centralized verification systems, which can lead to increased investment and maintenance costs over time.
Innovation Solution
A distributed verification system using a peer-to-peer blockchain network to identify and execute verification instructions on ADS-equipped vehicles, collect verification data, generate and log verification result transactions on a distributed ledger, thereby decentralizing the verification process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized verification system is used to verify ADS features, then verification results can be centrally collected and managed, but the complexity and maintenance costs of the system increase significantly over time
Solution Approach 1:
The patent divides the centralized verification system into distributed verification nodes deployed across multiple vehicles. Each vehicle independently executes verification instructions and stores results locally on the blockchain, eliminating the need for a single complex centralized system while maintaining verification reliability through distributed consensus mechanisms.
Solution Approach 2:
Vehicles autonomously perform verification tasks by executing instructions locally and automatically storing results on the blockchain without requiring centralized coordination. The system serves itself through peer-to-peer verification where vehicles contribute to the verification process and are rewarded with tokens, reducing maintenance overhead.
2Reliability
If a centralized verification system is used to collect and manage verification data, then data management is simplified, but investment and maintenance costs increase significantly
Solution Approach 1:
The verification system operates autonomously with vehicles self-managing data collection, validation, and storage on the blockchain. Smart contracts automatically handle verification logic execution and result recording, eliminating the need for expensive centralized infrastructure and reducing ongoing maintenance costs while ensuring traceability through immutable blockchain records.
Solution Approach 2:
The blockchain network serves multiple functions simultaneously: data storage, verification execution, result validation, and incentive distribution. This multi-functional approach replaces what would otherwise require separate centralized systems for each function, reducing overall investment and maintenance requirements.
3Measurement precision
If verification instructions are executed on customer fleets, then real-world verification data is obtained, but the process becomes complex and costly over time
Solution Approach 1:
Vehicles in the customer fleet autonomously execute verification instructions and contribute results to the blockchain without requiring complex centralized coordination. The peer-to-peer network automatically manages data aggregation and validation, maintaining high verification accuracy through real-world operational data while reducing process complexity through decentralized automation.

AI summary
A distributed verification system for supporting verification of ADS features within specific ODDs. The distributed verification system identifies at one or more ADS-equipped vehicles, a respective at least first verification instruction pertinent an at least first specified ODD of a specified ADS feature; collects at at least a first vehicle, verification data from execution by the at least first vehicle of the at least first ADS verification instruction while the specified ADS feature is active; generates at the at least first vehicle, a verification result transaction to be added to a distributed ledger of a block chain network, which verification result transaction includes verification information derived from the verification data along with information of circumstances and/or configuration of the at least first vehicle; and when consensus of the verification result transaction is reached on the network, adds the verification result transaction to the distributed ledger.
