Solution Overview

Problem

The field of view of side view mirrors in motor vehicles is typically set by drivers and remains unchanged, leading to potential turn collisions due to inadequate adjustment for varying driving conditions, especially when a lift axle is raised or lowered, altering the vehicle's turning radius.

Innovation Solution

A method and computer program product that adjust the display field of view of a side view camera system based on the lift axle position, using digital resizing, panning, and rotation, or mechanical adjustments to maintain the vehicle's end corner within the camera's view during turns, thereby adapting to changing turning radii and reducing blind spots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the field of view of side view mirror is set manually by driver and left unchanged, then the device complexity is reduced, but the reliability of avoiding turn collisions deteriorates due to inadequate adjustment for varying driving conditions

Engineering Contradiction:
Improveside view mirror adjustment systemVSAvoidcollision avoidance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The side view mirror field of view is changed from a static manual setting to a dynamic automatically adjusted view. The system continuously monitors lift axle position and vehicle turning status, automatically modifying the camera field of view and display image to maintain optimal viewing angles during turning operations, thereby adapting to varying driving conditions without increasing operational complexity for the driver

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback by continuously monitoring lift axle position sensors and vehicle status, then using this information to automatically adjust the side view camera field of view and display presentation. This closed-loop control ensures the mirror view remains optimized for collision avoidance during turning operations based on real-time vehicle configuration changes

Inventive Principle:
Principle #23Feedback

2Device complexity

If the side view camera field of view is adjusted digitally without mechanical movement, then the device complexity is reduced, but the area of visible field of view is limited compared to mechanical adjustment

Engineering Contradiction:
Improvecamera adjustment mechanismVSAvoidcamera field of view
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The camera field of view is dynamically adjusted through digital image processing rather than mechanical movement. The system processes camera capture data to generate adjusted display images that maintain proper vehicle corner visibility during turning, achieving adaptive field of view optimization without complex mechanical adjustment mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces mechanical camera adjustment mechanisms with digital image processing. Instead of physically moving the camera to change its field of view, the system uses digital resizing, panning, and rotation of captured images to achieve the same visual adjustment effect, thereby reducing mechanical complexity while maintaining field of view adaptability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A method of operating a computer system of a motor vehicle includes receiving, via a processor device of the computer system, camera image data captured by a side view camera of the motor vehicle, the camera image data comprising a camera field of view, displaying display image data on a display screen, the display image data comprising a display field of view of at least a portion of the camera field of view of the camera image data, and adjusting the display field of view during a turning operation of the motor vehicle based on a lift axle position of at least one lift axle of the motor vehicle.
