Autonomous Driving Remote Assistance Withholding by Influence Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote monitoring technologies for autonomous driving vehicles often result in unnecessary requests for operator intervention and inappropriate remote instructions due to inconsistent criteria for determining similarity of point information, leading to inefficiencies and operator workload.
Innovation Solution
An autonomous driving system that registers point information including location and extent of influence, temporarily withholding remote assistance requests within defined influence areas, allowing vehicles to continue autonomous driving until reaching the original assistance point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote assistance requests are generated based on inconsistent similarity criteria for point information, then operator intervention is triggered more frequently, but unnecessary operator requests and inappropriate remote instructions increase
Solution Approach 1:
The system pre-registers point information including location data and extent of influence before remote assistance is needed. When the autonomous vehicle approaches a registered point, the system compares current sensor data with pre-registered information to determine if remote assistance is truly necessary, preventing unnecessary operator requests
Solution Approach 2:
The system implements feedback by continuously monitoring the autonomous vehicle's location and comparing it with registered point information. The remote assistance device receives sensor data from the vehicle, determines similarity with pre-registered points, and only triggers operator intervention when genuine novel situations are detected, creating a closed-loop decision system
2Reliability
If remote assistance is provided frequently based on inconsistent criteria, then safety is maintained, but system efficiency decreases due to inappropriate remote instructions
Solution Approach 1:
The system applies different evaluation criteria based on location-specific characteristics. Each registered point contains location-specific information and extent of influence, allowing the system to make context-appropriate decisions about whether remote assistance is needed, rather than applying uniform thresholds everywhere
Solution Approach 2:
By pre-registering point information with location data and extent of influence parameters, the system establishes a knowledge base that enables efficient real-time decisions. The vehicle and remote assistance device can quickly determine if assistance is needed by comparing current state with pre-established criteria, maintaining safety without excessive intervention
3Productivity
If the system withholds remote assistance within defined influence areas, then unnecessary operator requests are reduced, but the system complexity increases
Solution Approach 1:
The system resolves complexity by performing the computationally intensive registration and analysis work in advance. Point information including location data and extent of influence is pre-calculated and stored, enabling simple real-time comparisons that withhold unnecessary remote assistance without requiring complex real-time processing
Solution Approach 2:
The registered point information acts as an intermediary layer between the autonomous vehicle and the remote assistance operator. This intermediate data structure (containing location and extent of influence) mediates the decision-making process, filtering out situations that don't require operator intervention while maintaining system safety

AI summary
An autonomous driving method for causing a computer to perform a process of registering, for each point where remote assistance has been performed in the past for any one of autonomous driving vehicles, point information indicating a location of the point, and at least an extent of influence defined by a distance from the location of the point, and a process of, upon occurrence of a request for remote assistance from any one of the autonomous driving vehicles within the extent of influence included in the registered point information, temporarily withholding execution of remote assistance and causing the autonomous driving vehicle to perform autonomous driving.
