Vehicle Road Projection Notification System for Target-Specific Message Adaptation

Solution Overview

Problem

Conventional techniques for notifying a driver's intention to pedestrians or animals around a vehicle are not accurate, particularly for those who cannot read specific languages or have difficulty understanding small letters or Chinese characters.

Innovation Solution

A notification control apparatus that includes an attribute detecting unit, an input recognizing unit, a message converting unit, and a road projection controller, which detects the attribute of objects around the vehicle, recognizes the driver's input message, converts it into a suitable notification message, and projects it onto the road, ensuring the message is understandable to the intended recipient.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a predetermined message is displayed to all notification targets regardless of their attributes, then the notification system is simple to operate, but the accuracy of displaying the driver's intention to the notification target deteriorates

Engineering Contradiction:

Improveaccuracy of displaying driver's intentionVSAvoidcomplexity of notification system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The notification message is customized according to the specific attributes of each notification target (pedestrian, cyclist, animal). The system detects attributes such as human/non-human, and adjusts the message content locally for each target type rather than using a uniform message for all targets, thereby improving communication effectiveness.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The notification system changes the parameters of the message based on the detected attributes of the notification target. By detecting whether the target is a human or animal and other attributes, the system modifies message parameters (content, language, symbols) to optimize understanding for each specific target type.

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If small letters or Chinese characters are used in the notification message, then the message conveys precise information, but the ease of understanding by elderly persons or children deteriorates

Engineering Contradiction:

Improveinformation transmission accuracyVSAvoidease of understanding for notification target

Core Design Contradiction:

Loss of informationVSEase of operation

AI summary

An object of the present invention to provide a notification control apparatus and a method for controlling notification that achieve display to a notification target with improved accuracy. A notification control apparatus in the present invention includes the following: an attribute detecting unit that detects an attribute of an object located around a subject vehicle; an input recognizing unit that recognizes an input message entered by the driver of the subject vehicle; a message converting unit that converts, in accordance with the attribute detected by the attribute detecting unit, the input message recognized by the input recognizing unit into a notification message indicating the same meaning as the input message; and a road projection controller that controls projection of the notification message converted by the message converting unit onto at least part of a road located around the object.
