Solution Overview

Problem

Current blind spot detection systems in vehicles, including both mechanical and virtual mirrors, fail to provide full 360-degree visibility, leading to increased risks of collisions due to blind spots, especially in adverse weather conditions and when environmental factors interfere with sensor accuracy.

Innovation Solution

A method that automatically adjusts the field of view of a camera-based virtual mirror by zooming in or out based on the detection of nearby vehicles, switching to a wider field of view when a vehicle is detected in the blind spot and reverting to a narrower view when safe, to enhance driver visibility and reaction time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a fixed field of view is used in virtual mirrors, then the device complexity is reduced, but the blind spot coverage is insufficient

Engineering Contradiction:
Improveblind spot coverageVSAvoiddevice complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent implements dynamic field of view adjustment by switching between wide-angle and narrow-angle camera views based on detected vehicle presence. The system transitions from a static mirror view to a dynamic virtual mirror that adapts its field of view, eliminating blind spots when vehicles are detected while maintaining simplicity when the area is clear.

Inventive Principle:
Principle #15Dynamics

2Difficulty of detecting and measuring

If sensor-based blind spot detection is used, then the detection capability is improved, but the reliability deteriorates in poor weather conditions

Engineering Contradiction:
Improvedetection capabilityVSAvoidreliability
Core Design Contradiction:
Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The patent uses the camera system as an intermediary visual verification tool that complements sensor-based detection. When sensors detect a vehicle, the system switches to a wide-angle camera view to visually confirm the vehicle's presence and provide the driver with direct visual information, bypassing the reliability issues of sensor-based detection in adverse weather.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of stationary object

If a wide field of view is always used, then the blind spot visibility is improved, but the manufacturing precision of the mirror image is reduced

Engineering Contradiction:
Improvevisibility areaVSAvoidmirror image quality
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The system dynamically switches between wide-angle and narrow-angle camera views based on the presence of vehicles in blind spots. When no vehicles are detected, the system uses the narrow-angle view to provide high-quality, distortion-free mirror images. When vehicles are detected, it switches to the wide-angle view to capture the full visibility area, thus optimizing both image quality and coverage at different times.

Inventive Principle:
Principle #15Dynamics

AI summary

In one approach, a method includes: displaying, to a user of a first vehicle, image data obtained using a first field of view of a camera of the first vehicle, where the camera collects the image data for objects located outside of the first vehicle; detecting, by at least one processing device of the first vehicle, a second vehicle; determining, by the one processing device, whether the second vehicle is within a predetermined region relative to the first vehicle; and in response to determining that the second vehicle is within the predetermined region, displaying image data obtained using a second field of view of the camera.
