Autonomous Vehicle Ledger for Smart Contract Liability Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a trusted mechanism to automatically enforce liability arrangements associated with autonomous vehicles, as they shift between manual and autonomous control, leading to unclear liability shifts and a lack of transparent and objective regulation.
Innovation Solution
A distributed ledger system is used to record and enforce smart contracts related to autonomous vehicle operations, monitoring sensors to generate transactions that update the ledger, allowing for automatic enforcement of liability based on predefined conditions and states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a distributed ledger system is implemented to automatically enforce smart contracts, then transparency and objectivity of liability enforcement is improved, but system complexity and implementation difficulty increases
Solution Approach 1:
The patent introduces a distributed ledger system as an intermediary layer between autonomous vehicle operations and liability enforcement. The ledger acts as a neutral mediator that automatically executes smart contracts based on sensor data, removing the need for manual liability determination and ensuring transparent, objective enforcement without requiring complex centralized authority structures.
Solution Approach 2:
The system enables self-service through automated smart contract execution. When predefined conditions are met (detected via sensor monitoring), the smart contracts automatically enforce liability arrangements without human intervention. This self-executing mechanism reduces implementation complexity by eliminating the need for manual processing while maintaining high reliability and transparency.
2Measurement precision
If sensor monitoring and transaction generation are implemented for every autonomous vehicle, then accuracy of liability determination is improved, but data processing load and network bandwidth consumption increases
Solution Approach 1:
The system implements partial monitoring by focusing sensor attention only on conditions relevant to smart contract enforcement rather than continuously monitoring all vehicle parameters. Transactions are generated selectively based on predefined triggers and conditions, reducing unnecessary data transmission while maintaining accurate detection of liability-relevant events.
Solution Approach 2:
The patent extracts only the essential data elements needed for smart contract execution from the vast amount of sensor data generated by autonomous vehicles. By filtering and selecting only relevant transactions for ledger inclusion, the system maintains high measurement precision for liability determination while minimizing network bandwidth consumption by excluding redundant data.
3Productivity
If automatic smart contract enforcement is implemented, then speed of liability resolution is improved, but risk of automated errors and lack of human oversight increases
Solution Approach 1:
The distributed ledger system incorporates feedback mechanisms where sensor data continuously monitors vehicle conditions and automatically triggers smart contract execution when predefined conditions are met. The system provides real-time feedback loops that verify condition satisfaction and execute appropriate liability enforcement, ensuring both speed and reliability through automated validation rather than human review.

AI summary
Methods and systems for maintaining a distributed ledger and/or blockchain of transactions and/or events pertaining to autonomous vehicles and/or smart contracts are provided. One or more processors may monitor one or more sensors associated with an autonomous vehicle. Based upon the outputs of the sensors, a change in condition of the autonomous vehicle may be detected. The condition may relate to operation, or an operational state of the vehicle and/or a condition associated with a smart contract. The processors may generate a transaction describing the detected change in the condition of the vehicle. The transaction may be transmitted to an enforcement server. As a result, an up-to-date ledger of autonomous vehicle and/or smart contract transactions and/or events may be maintained.
