Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional lane change controlling systems fail to effectively interrupt or cancel a lane change procedure after it has started, leading to potential safety issues and user discomfort when conditions such as dangerous situations or user intervention occur.

Innovation Solution

A vehicle control system that includes a processor to determine whether to interrupt or cancel a lane change procedure based on conditions like dangerous situations, user input, or system limitations, and to return the vehicle to its original lane, with notifications and adjusted returning areas calculated based on vehicle leaning and error values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the lane change controlling system automatically controls the vehicle to perform lane change when driver manipulates turn signal, then lane change operation is completed, but the system cannot interrupt the lane change procedure after it has started

Engineering Contradiction:

Improvelane change operationVSAvoidlane change interruption capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the lane change control based on real-time conditions. The processor continuously monitors whether interruption conditions occur during the lane change procedure and dynamically switches between completing the lane change and interrupting it, allowing the system to adapt to changing situations while maintaining ease of operation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback by continuously monitoring conditions during lane change execution. The processor determines whether interruption conditions occur based on feedback from sensors and system state, and adjusts control accordingly, enabling both automatic lane change completion and interruption capability

Inventive Principle:

Principle #23Feedback

2Reliability

If the system determines whether to interrupt lane change procedure or return to original lane, then user safety is improved, but the control logic complexity increases

Engineering Contradiction:

Improveuser safetyVSAvoidcontrol logic

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The control logic is segmented into distinct decision points: determining whether interruption conditions occur, and if so, determining whether to interrupt the procedure or return to the original lane. This segmentation of control functions makes the complex logic more manageable and implementable while maintaining high reliability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary determination of interruption conditions before executing the final control action. By first determining whether interruption conditions occur and then determining the appropriate response (interrupt or return), the system prepares control decisions in advance, reducing actual response time while maintaining safety

Inventive Principle:

Principle #10Preliminary action

AI summary

An apparatus for controlling a lane change of a vehicle may include: a processor determining whether a condition of interrupting a lane change procedure occurs, during controlling the lane change. In particular, when the condition of interrupting the lane change procedure is satisfied, the processor determines whether to interrupt the lane change procedure or whether to return the vehicle to an original lane to control the vehicle depending on a result of the determinations. The apparatus further includes a storage to store the result determined by the processor.
