Solution Overview

Problem

Drivers face challenges in maintaining forward visibility due to pitch rotations of the vehicle caused by changing road inclinations, leading to difficulties in perceiving the road surface condition and increased accident risks, especially when driving over speed bumps, sidewalks, or entering underground parking lots.

Innovation Solution

A system and method for drive control of a front surround view monitoring (SVM) system that analyzes road surface conditions using image data and LiDAR sensing to automatically activate the front SVM system when significant inclinations are detected, ensuring continuous driver assistance and improved visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the driver relies on direct forward visibility while driving on roads with changing inclinations, then the driver can naturally perceive the road surface condition, but pitch rotation of the vehicle causes the driver to lose forward visibility and makes it difficult to check the ground situation

Engineering Contradiction:
Improveforward visibilityVSAvoiddriver's view
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a front SVM system as an intermediary to provide visual information about the road surface condition when direct visibility is compromised by pitch rotation. The system uses cameras and image processing to generate a virtual view of the front ground, allowing the driver to check road conditions without relying on direct line-of-sight visibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the front SVM function is activated to maintain forward visibility during pitch rotation, then the driver can check the ground situation, but the driver is required to perform separate manipulation to activate the function

Engineering Contradiction:
Improveforward visibilityVSAvoidseparate manipulation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically detects pitch rotation using vehicle sensor data (accelerometer, gyroscope) and activates the front SVM function without requiring driver intervention. The system serves itself by monitoring its own operational state and making autonomous decisions about when visual assistance is needed, eliminating the need for separate manual activation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors vehicle pitch angle through sensor feedback and automatically activates or deactivates the front SVM function based on whether pitch rotation exceeds a predetermined threshold. This closed-loop control ensures the function is activated only when necessary, maintaining visibility without requiring manual operation.

Inventive Principle:
Principle #23Feedback

3Reliability

If the front SVM image is displayed to help the driver check the ground situation, then the driver can perceive forward conditions, but the function is automatically released when vehicle speed reaches 15 km/h or more, reducing driving concentration

Engineering Contradiction:
Improveforward visibilityVSAvoidfunction availability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the activation criteria of the front SVM function by considering both vehicle speed and pitch angle. Instead of using a fixed speed threshold, the system activates the function when pitch rotation exceeds a predetermined angle threshold, regardless of speed. This allows the function to remain available in low-speed scenarios with significant pitch rotation (such as over speed bumps or sidewalk transitions) while avoiding unnecessary activation during normal driving at higher speeds.

Inventive Principle:
Principle #15Dynamics
