Solution Overview

Problem

Autonomous vehicles face inefficiencies in decision-making during blockade situations, often requiring unnecessary teleoperator intervention or prolonged waiting times due to the inability to assess and manage blockade durations effectively without human input.

Innovation Solution

The method enables autonomous vehicles to predict blockade time durations using situational analysis from sensor systems and learning processes, deciding whether to request teleoperator support based on predetermined time thresholds, thereby reducing unnecessary waiting and energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the vehicle autonomously waits for blockade resolution without teleoperator support, then teleoperator burden is reduced, but waiting time may become unnecessarily long

Engineering Contradiction:
Improveteleoperator burdenVSAvoidblockade waiting time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The vehicle autonomously assesses blockade situations using its sensor systems and learning model, deciding whether to wait or request teleoperator support without constant human intervention. The vehicle serves itself by making initial decisions based on predicted blockade time durations, reducing teleoperator burden while maintaining efficient resolution

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from sensor systems continuously monitoring the blockade situation to update the learning model and adjust decision-making. The vehicle receives feedback about blockade resolution status and uses this to refine its predictions and decisions, balancing autonomous operation with teleoperator support

Inventive Principle:
Principle #23Feedback

2Reliability

If the vehicle requests teleoperator support for all blockade situations, then blockade resolution is ensured, but operational costs and teleoperator workload increase

Engineering Contradiction:
Improveblockade resolution assuranceVSAvoidoperational efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The vehicle independently evaluates blockade situations using its learning model and sensor data, autonomously deciding when teleoperator support is actually needed. This self-assessment capability allows the system to handle routine blockades independently, reserving teleoperator resources for complex or uncertain situations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes the parameter of teleoperator involvement from constant to conditional, based on the predicted blockade time duration and situational assessment. The vehicle dynamically adjusts its operational mode between autonomous waiting and teleoperator consultation based on real-time parameters

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If the vehicle uses complex situational analysis and learning models to predict blockade duration, then decision accuracy improves, but device complexity increases

Engineering Contradiction:
Improveblockade time prediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The learning model is pre-trained with extensive data about various blockade situations, objects, and time durations before deployment. This preliminary training allows the vehicle to make accurate predictions using established patterns without requiring complex real-time calculations, reducing operational complexity while maintaining prediction accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The learning model acts as an intermediary between raw sensor data and decision-making, translating complex sensor inputs into predicted blockade time durations. This intermediary layer simplifies the decision process by providing a single predicted duration value that the vehicle can compare against thresholds

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

When a vehicle performing driverless operation of encounters a blockade situation, a probable blockade time duration of the blockade situation is predicted based on a situational analysis. Support by a teleoperator is requested when the predicted blockade time duration of the blockade situation is greater than a predetermined time duration or when the vehicle has waited longer than the predicted blockade time duration for a resolution of the blockade situation.
