Driving Support Apparatus Intersection Turn Intent

Solution Overview

Problem

Existing driving support apparatuses provide unnecessary information when a vehicle turns on its blinker for lane changes or passing, failing to notify the driver of necessary information, such as oncoming vehicles or pedestrians, especially when the blinker turns off prematurely during turns.

Innovation Solution

A driving support apparatus that includes a controller, current position detector, and driving direction determination unit, which sets an enforcement notification state to provide necessary information even when the blinker turns off, determining the vehicle's intention to turn based on its position and direction, and ends the notification state when no turn is intended, thus restricting unnecessary information service.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the apparatus provides information only when the blinker is turning on, then unnecessary information service is restricted, but necessary information may not be provided when the blinker turns off prematurely during turns

Engineering Contradiction:

Improveinformation provision reliabilityVSAvoidnecessary information loss

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The apparatus determines the vehicle's turning intention in advance by analyzing the trajectory before the blinker turns off, and maintains information provision based on this predetermined intention rather than solely relying on real-time blinker status

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The apparatus continuously monitors the vehicle's trajectory and compares it with expected turning paths, using this feedback to determine whether to maintain information provision even when the blinker turns off

Inventive Principle:

Principle #23Feedback

2Loss of information

If the apparatus provides information based on blinker status and distance to intersection, then information about oncoming vehicles is provided, but unnecessary information is provided when the vehicle merely changes lane or passes other vehicles

Engineering Contradiction:

Improveinformation completenessVSAvoidunnecessary information service

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The apparatus dynamically adjusts the information provision strategy based on real-time trajectory analysis, transitioning from static blinker-based control to dynamic trajectory-based control that adapts to actual driving intentions

Inventive Principle:

Principle #15Dynamics

AI summary

A driving support apparatus includes: a driving support controller for starting to execute a driving support control when a support start condition is met; a current position detector; and a driving direction determination unit for successively determining whether there is a possibility of a vehicle turning at an intersection in a direction, to which a blinker turns. The driving support controller sets an enforcement notification state when the driving direction determination unit determines the possibility after the driving support controller starts to execute the driving support control. The driving support control provides to notify information in the enforcement notification state even when the blinker turns off, and ends the enforcement notification state when the driving direction determination unit determines no possibility.
