Solution Overview

Problem

Traditional vehicular warning systems have a fixed warning zone that fails to cover blind areas created during vehicle turns, making it difficult to detect obstacles in these regions.

Innovation Solution

A vehicular warning apparatus and auxiliary-line adjusting apparatus that dynamically adjust the first and second auxiliary lines based on the vehicle's turning signal, expanding the warning zone to cover blind areas by altering the auxiliary lines in response to steering wheel rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed warning zone is used, then the system structure is simple, but the warning zone cannot cover blind areas during vehicle turns

Engineering Contradiction:
Improvewarning zone coverageVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the warning zone boundaries dynamic rather than fixed. The auxiliary lines that define the warning zone are dynamically adjusted based on vehicle turning signals and steering wheel position. When the vehicle turns, the warning zone automatically expands or shifts to cover the newly created blind areas, resolving the contradiction between maintaining simple system structure and achieving adaptable warning zone coverage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the geometric parameters of the warning zone (position, orientation, and extent of auxiliary lines) in response to vehicle state parameters (turning signal status, steering angle). This allows the warning zone to adapt its coverage area based on actual driving conditions, enabling blind area coverage during turns without requiring a completely complex reconfiguration system.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the warning zone is expanded to cover blind areas, then obstacle detection capability is improved, but the system complexity increases

Engineering Contradiction:
Improveobstacle detection reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs feedback by continuously monitoring vehicle state parameters (turning signals, steering wheel position) and using this information to adjust the warning zone configuration. This closed-loop feedback mechanism ensures that the warning zone reliably covers blind areas during turns while maintaining system simplicity through automated parameter adjustment based on real-time vehicle state feedback.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies self-service by automatically adjusting its own warning zone parameters based on vehicle operating conditions without requiring external intervention. The processor autonomously modifies the auxiliary line positions and orientations in response to turning signals and steering input, enabling the system to self-adapt and maintain reliable obstacle detection across varying driving scenarios.

Inventive Principle:
Principle #25Self-service

AI summary

A vehicular warning apparatus and a vehicular auxiliary-line adjusting apparatus are provided. The vehicular warning apparatus includes an image capturing device, a vehicular control-signal capturing device and a processor. The image capturing device captures an image outside of a vehicle. The vehicular control-signal capturing device captures a turning signal of the vehicle. The processor defines a first auxiliary line and a second auxiliary line, and determines whether a target object of the image touches a warning zone formed between the first auxiliary line and the second auxiliary line, and accordingly generates a warning signal. The processor also dynamically adjusts the first auxiliary line and/or the second auxiliary line according to the turning signal so as to adjust the warning zone.
