Solution Overview

Problem

Delays in wireless communication between onboard and terminal apparatuses can result in the presentation of captured images at past times, making it difficult to provide real-time information about the vehicle's surroundings.

Innovation Solution

Generating and presenting a predicted image based on the captured image and vehicle state information, accounting for the delay time in wireless communication, to ensure real-time representation of the vehicle's environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If captured images are transmitted via wireless communication between onboard and terminal apparatuses, then image information can be presented on the terminal apparatus, but communication delay causes the presented image to be from past time rather than real-time

Engineering Contradiction:
Improvereal-time accuracy of presented imageVSAvoidwireless communication delay time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by calculating the delay time in advance and using this information to select and present appropriate images. The terminal apparatus predicts what the current image should look like based on the delay characteristics of the communication channel, rather than simply displaying the most recently received image.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by using the known delay time to adjust image presentation. The terminal apparatus receives information about communication delay and uses this feedback to compensate for the delay effect, selecting images that represent the current real-time state rather than past states.

Inventive Principle:
Principle #23Feedback

2Productivity

If the terminal apparatus presents the most recently received captured image, then the image transmission is simple, but the presented image does not represent the current real-time state due to communication delay

Engineering Contradiction:
Improveimage presentation speedVSAvoidtiming accuracy of presented image
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system calculates the delay time in advance and uses this pre-computed information to guide image selection. By knowing the delay characteristics beforehand, the terminal apparatus can directly select the appropriate image without complex real-time adjustments, maintaining high presentation speed while improving timing accuracy.

Inventive Principle:
Principle #10Preliminary action
