Verified Vehicle Maneuver Download With Score-Based Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle maneuver sharing systems lack security measures to ensure that only verified and safe maneuvers are downloaded and executed, potentially leading to hazardous situations.
Innovation Solution
A method and server system that record, test, and verify vehicle maneuvers based on specific conditions, assigning an assessment score only when it meets a threshold value, allowing verified maneuvers to be downloaded to other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle maneuvers are shared without verification, then ease of operation is improved, but reliability deteriorates due to potential hazardous maneuvers
Solution Approach 1:
The system performs preliminary verification of maneuvers before they are shared with other vehicles. The verification module tests maneuvers under simulated conditions and assigns confidence scores beforehand, ensuring that only pre-verified safe maneuvers are made available for download, thus maintaining both ease of operation and reliability
Solution Approach 2:
The verification module acts as an intermediary between maneuver generation and maneuver sharing. It introduces a confidence score assessment mechanism that mediates which maneuvers are suitable for sharing, preventing hazardous maneuvers from being distributed while allowing safe ones to be shared easily
2Reliability
If verification testing is performed on multiple vehicles, then reliability is improved, but loss of time increases due to extensive testing requirements
Solution Approach 1:
The system creates virtual copies of maneuver testing environments through simulation. Instead of physically testing on multiple real vehicles, the verification module uses simulated vehicle models to replicate testing conditions, significantly reducing time loss while maintaining verification accuracy through multiple virtual test iterations
Solution Approach 2:
The system changes the testing parameters by transitioning from physical vehicle testing to simulated environment testing. This parameter change allows parallel testing across multiple virtual vehicles simultaneously, improving reliability through extensive testing while minimizing time loss
3Reliability
If confidence scores are assigned to maneuvers, then reliability is improved, but device complexity increases due to additional assessment mechanisms
Solution Approach 1:
The verification module performs self-assessment of maneuvers by automatically generating confidence scores based on simulated testing results. The system serves itself by autonomously evaluating maneuver safety without requiring complex external assessment infrastructure, thus improving reliability while limiting the increase in device complexity

AI summary
There is provided mechanisms for enabling download of verified vehicle manoeuvres. A method comprises recording, in a database, a manoeuvre as having been performed by a first vehicle at a location and according to a set of conditions of the first vehicle and a set of conditions of the location. The method comprises assigning an assessment score to the manoeuvre upon the manoeuvre having been tested for at least one second vehicle. The manoeuvre is tested under test conditions given by the location, the set of conditions of the first vehicle and the set of conditions of the location. The method comprises determining the manoeuvre to be verified only when the assessment score is above a threshold value. The method comprises enabling download of the manoeuvre from the database to at least one third vehicle only in case the manoeuvre is verified.
