Solution Overview

Problem

Existing methods for autonomous vehicle merging from a slip road into traffic lanes do not adequately account for human behavior and traffic conditions, leading to potential obstructions and discomfort in the merging process.

Innovation Solution

The method determines a primary merging position based on observed traffic data, using cameras or drones for aerial observation, and adjusts it to typical human merging patterns, with the option to switch to a secondary position if the primary position causes obstruction, ensuring a comfortable and safe merge by minimizing delays to other road users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the lane change is carried out at the primary merging position, then the merging process is efficient and follows typical human behavior, but it may cause obstruction to road users in the lane of traffic

Engineering Contradiction:
Improvemerging efficiencyVSAvoidobstruction to road users
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The merging position is made dynamic rather than fixed. The system determines a primary merging position based on typical human behavior, but dynamically adjusts to a secondary position when obstruction is detected, allowing the system to adapt to real-time traffic conditions while maintaining efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors the lane of traffic for road users and detects potential obstructions. This feedback mechanism allows the system to switch from the primary merging position to a secondary position when necessary, resolving the contradiction between efficiency and safety

Inventive Principle:
Principle #23Feedback

2Object-affected harmful factors

If the lane change is delayed to avoid obstruction, then road users are not obstructed, but the merging process takes longer and deviates from typical human behavior

Engineering Contradiction:
Improveobstruction to road usersVSAvoidmerging delay
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system performs preliminary detection of road users in the lane of traffic before executing the lane change. By identifying potential obstructions in advance, the system can make informed decisions about merging position selection, minimizing delays while preventing obstruction to other road users

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If a fixed merging position is used, then the merging process is simple to implement, but it cannot adapt to varying traffic conditions and human behavior patterns

Engineering Contradiction:
Improvemerging control complexityVSAvoidadaptation to traffic conditions
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The merging control is segmented into distinct components: determination of primary merging position based on typical behavior, detection of road users, and selection of secondary positions when needed. This segmentation maintains relative simplicity while enabling adaptation to varying traffic conditions

Inventive Principle:
Principle #1Segmentation

AI summary

A method for the automatic merging of a vehicle from a slip road into a lane of traffic involves determining a primary merging position in advance at which the vehicle is to undertake a lane change from the slip road to the lane of traffic. If the lane change at the primary merging position or as close as possible to it does not lead to road users in the lane of traffic being obstructed, the vehicle is controlled in such a way that the lane change is carried out at the primary merging position. Otherwise, the lane change is carried out at a secondary merging position which is determined depending on detected clearances between road users in the lane of traffic.
