Solution Overview

Problem

Current vehicle lane detection and surrounding vehicle recognition methods are hindered by environmental factors like weather and brightness, leading to increased collision risks when changing lanes without determining the intentions of surrounding vehicles.

Innovation Solution

A system and method that selects surrounding vehicles, determines their intentions using location and speed information, predicts their driving routes, and creates a host vehicle route to avoid collisions by generating a grid map of predicted routes, employing Delaunay triangulation, deep learning, and machine learning techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If camera or sensor based lane detection is used, then lane detection is possible in clear weather, but detection fails or becomes unreliable in dark or bad weather conditions

Engineering Contradiction:
Improvelane detection reliabilityVSAvoidenvironmental factors (weather, brightness)
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces communication-based vehicle information as an intermediary to supplement sensor-based detection. By receiving location and speed data from surrounding vehicles through communication techniques, the system compensates for sensor failures in adverse weather conditions, creating a redundant information source that maintains detection reliability when primary sensors fail.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If lane changing is performed without determining surrounding vehicle intentions, then lane changing speed is fast, but collision risk increases

Engineering Contradiction:
Improvelane changing speedVSAvoidcollision safety
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent applies preliminary action by determining the intentions of surrounding vehicles before executing lane changing maneuvers. The system analyzes location and speed data to predict whether surrounding vehicles will change lanes, and only proceeds with lane changing when it is safe to do so, thereby preventing collisions while maintaining efficient lane changing speed.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If sensor based surrounding vehicle recognition is used, then vehicle location and speed can be detected, but intentions of surrounding vehicles cannot be determined

Engineering Contradiction:
Improvevehicle location and speed detectionVSAvoidvehicle intention information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent makes the system multi-functional by using communication techniques to gather not only location and speed data but also intention information from surrounding vehicles. The same communication infrastructure that provides basic vehicle data is also used to determine lane changing intentions, allowing the system to perform multiple functions (detection and prediction) through a unified approach.

Inventive Principle:
Principle #6Universality (Multi-functionality)
