Solution Overview

Problem

Existing vehicle inspection systems fail to confirm whether a repaired driving assistance device, which controls vehicle speed and assists driving in an automated manner, can exhibit its original performance post-repair.

Innovation Solution

A vehicle inspection method and system that utilizes a vehicle support device to maintain wheel rotation, an image generation device to create a synchronized virtual image of the forward environment, and an image display device to show this image, allowing for the inspection of driving assistance functions such as automatic braking, constant speed travel, and lane departure prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a driving assistance device is repaired and conventional inspection methods are used, then basic functionality can be confirmed, but the device's original performance cannot be verified

Engineering Contradiction:
Improveperformance verification accuracyVSAvoidinspection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a virtual image that copies the real-world environment seen by the camera. This virtual copy allows inspection of the driving assistance device's automated control functions without needing actual road conditions, thereby verifying original performance while avoiding complex real-world testing setups

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a virtual image as an intermediary between the camera and the inspection process. This virtual image serves as a mediator that allows the driving assistance device to process and respond to simulated environmental conditions, enabling performance verification without direct real-world testing

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If real-world road testing is conducted to verify driving assistance device performance, then accurate performance confirmation is possible, but safety risks and time consumption increase

Engineering Contradiction:
Improveperformance confirmation accuracyVSAvoidinspection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent generates a virtual image in advance that represents various road environments and conditions. This preliminary creation of test scenarios allows the driving assistance device to be inspected without actual road testing, significantly reducing inspection time while maintaining verification accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By creating a virtual copy of real-world driving environments, the system enables performance verification without physical road testing, thereby eliminating time loss associated with actual road tests while maintaining accurate performance confirmation

Inventive Principle:
Principle #26Copying

3Reliability

If actual road testing is performed to inspect driving assistance functions, then comprehensive performance verification is achieved, but safety hazards and operational disruptions occur

Engineering Contradiction:
Improveperformance verification completenessVSAvoidsafety risks during inspection
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates a virtual representation of the road environment that the camera can capture. This virtual copy allows comprehensive inspection of driving assistance functions including automatic braking, constant speed travel, and lane departure prevention without exposing the vehicle to actual road safety risks

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The virtual image acts as an intermediary that mediates between the camera and the inspection process. It provides a safe intermediate environment where all driving assistance functions can be tested comprehensively without the safety hazards associated with actual road testing

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A vehicle inspection method for a vehicle including a controller configured to control vehicle speed in an automated manner, based on a forward looking image, the vehicle inspection method including: supporting a wheel of the vehicle by a vehicle support device; acquiring a vehicle speed signal of the vehicle supported by the vehicle support device; generating a virtual image of an environment seen in a forward direction from the vehicle in such a way that the virtual image synchronizes with the vehicle speed signal; and displaying the virtual image in such a way that a camera, the camera being mounted on the vehicle and configured to generate the forward looking image, captures the virtual image.
