Right-Turn Intention Detection for Reliable Collision Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle right turn assistance systems are unreliable due to driver errors in operating turn signals or system malfunctions, leading to potential collisions.
Innovation Solution
A vehicle notification system that detects a vehicle's direction change intention using high-accuracy positioning and digital maps, independent of turn signal operations, and issues notifications to avoid collisions with oncoming vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If turn signal operation detection is used to trigger right turn assistance, then the system can be simple and easy to operate, but the reliability decreases due to driver errors and system malfunctions
Solution Approach 1:
The patent introduces an intermediary detection mechanism that monitors multiple parameters (positioning data, digital map information, vehicle state) between the driver's intention and the assistance system activation. This intermediary layer filters out false triggers from simple turn signal operations while ensuring reliable detection of genuine right turn intentions, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The detection unit is designed to perform multiple functions: it not only detects turn signal operations but also analyzes positioning data, compares it with digital map information, and determines vehicle state. This multi-functional approach consolidates several detection tasks into a single comprehensive system, improving reliability without proportionally increasing complexity.
2Loss of information
If driver operation of turn signal is required, then the system is easy to operate, but driver errors cause loss of information about right turn intention
Solution Approach 1:
The system implements feedback by continuously monitoring positioning data and comparing it with digital map information to verify whether the vehicle is actually executing a right turn. This feedback mechanism ensures that right turn intention information is not lost due to driver errors in operating the turn signal, as the system independently verifies the intention through multiple data sources.
Solution Approach 2:
The detection unit performs preliminary analysis of positioning data and vehicle state before triggering the right turn assistance. By proactively verifying the driver's intention through multiple parameters before activation, the system prevents information loss that would occur if it relied solely on turn signal operation, which may be delayed or incorrect.

AI summary
A vehicle notification system 1 includes: a right turn intention detection unit B114a that detects a right turn intention of a right turning vehicle VA the basis of a current position Pa of the vehicle VA on a road map specified on the basis of high accuracy positioning information and a high accuracy digital map; and notification issuing units B118a and B119a that perform notification issuance to avoid collision between the right turning vehicle VA and a straight traveling vehicle VB traveling straight in a straight lane L22 opposite to a traveling lane L11 where the right turning vehicle VA is present after the right turn intention detection unit B114a detects the right turn intention.
