Lane Keeping Notification System for Low Recognition Zones

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional lane keeping systems in vehicles struggle to notify drivers when lane recognition is difficult due to deteriorated lanes or adverse weather, leading to sudden shutdowns and inadequate communication about the functionality of the lane keeping feature.

Innovation Solution

An information processing system that acquires and analyzes real-time use information from vehicles equipped with lane keeping functions, identifies regions with low use rates, and transmits notification information to vehicles approaching those areas, allowing for proactive warnings and potential temporary shutdowns of the lane keeping function based on calculated temporary stop rates and environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the lane keeping function is stopped suddenly when lanes are difficult to recognize, then the system avoids incorrect operation, but the driver is not notified and driving continuity is disrupted

Engineering Contradiction:

Improvelane keeping function reliabilityVSAvoiddriver notification information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary actions by collecting lane keeping function status data from multiple vehicles before a problem occurs. The server analyzes this data to identify regions where lane recognition is difficult, and sends notification information to vehicles before they enter these regions, allowing drivers to prepare in advance rather than reacting to sudden shutdowns.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where lane keeping function usage data from multiple vehicles is continuously collected and analyzed by the server. This feedback mechanism enables the system to identify patterns and regions with recognition difficulties, then communicate this information back to drivers to improve their awareness and preparedness.

Inventive Principle:

Principle #23Feedback

2Loss of time

If map data is used to determine lane keeping availability, then the system can notify drivers in advance, but it cannot detect actual lane conditions that deteriorate after map data creation

Engineering Contradiction:

Improvenotification timingVSAvoidlane condition detection accuracy

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The system uses self-service by leveraging the lane keeping function data already being collected from multiple vehicles for its primary purpose. This existing data is repurposed to identify regions with recognition difficulties, eliminating the need for separate detection infrastructure while providing real-time condition feedback that complements static map data.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system achieves multi-functionality by using lane keeping function usage data for dual purposes: maintaining lane keeping operation and simultaneously identifying regions with recognition difficulties. This same data stream serves both the operational control function and the notification function, making the system more versatile without adding separate detection systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the lane keeping function is stopped due to worn or dirty lanes, then the system maintains safety, but the driver cannot be notified in advance as the condition is temporary and localized

Engineering Contradiction:

Improvesafe operationVSAvoiddriver awareness information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary analysis by collecting lane keeping function data from multiple vehicles to identify regions with recognition difficulties before individual vehicles encounter problems. This allows the server to send notification information in advance to drivers approaching these regions, even when the actual cause (worn or dirty lanes) is temporary and localized.

Inventive Principle:

Principle #10Preliminary action

4Measurement precision

If real-time use information from multiple vehicles is collected and analyzed, then the system can identify regions with recognition difficulties, but the system complexity increases

Engineering Contradiction:

Improveregion identification accuracyVSAvoiddata collection and processing system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system introduces a server as an intermediary that centralizes the complex tasks of data collection, analysis, and notification management. Individual vehicles only need to transmit their lane keeping function status data and receive notifications, while the server handles the sophisticated analysis of multiple data streams to identify regions with recognition difficulties. This distributes complexity from individual vehicles to a centralized system.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information processing device includes circuitry configured to acquire, from vehicles each of which has a lane keeping function of allowing each of the vehicles to travel along a lane, a use information of the lane keeping function during a travel, extract a region in which a use rate of the lane keeping function is low, on the basis of the use information, and transmit a notification information based on the use rate to a given vehicle having the lane keeping function.
