Solution Overview

Problem

Current vehicle surround view systems lack a realistic perspective view of vehicle models, leading to potential driver distraction and reduced understanding of displayed information.

Innovation Solution

A method for controlling an optical output device to display a vehicle surround view by determining display control information for vehicle components, such as wheels, lights, and interior/exterior features, based on their operational states and user configuration, to create a more intuitive and realistic graphical representation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a vehicle surround view system displays a vehicle model with basic geometric representation, then the system complexity is low and implementation is simple, but the driver understanding and perception of the displayed information is reduced

Engineering Contradiction:
Improvedriver understandingVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies the Dynamics principle by making the vehicle model in the surround view display dynamically adapt to real-time vehicle component states. The system continuously updates the graphical representation of vehicle components (wheels, lights, doors, windows) based on their current operational states, transforming a static geometric model into a dynamic, state-responsive visualization that enhances driver understanding without requiring fundamental system redesign

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes the Color changes principle to improve information perception by varying the visual appearance of vehicle components in the surround view display. Different colors and visual styles are applied to represent different operational states of vehicle components (e.g., illuminated lights, open/closed doors, rotating wheels), making the display more intuitive and easier for drivers to understand at a glance

Inventive Principle:
Principle #32Color changes

Solution Approach 3:

The patent applies the Segmentation principle by breaking down the vehicle model into individual controllable components (wheels, lights, doors, windows, body). Each component can be independently controlled and updated based on its specific operational state, allowing the system to manage complexity through modular organization while providing comprehensive real-time feedback to the driver

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the vehicle model in the surround view is static and does not reflect real-time component states, then the system operation is simple, but the driver perception and understanding of vehicle actions is reduced

Engineering Contradiction:
Improvesystem operationVSAvoiddriver perception
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements the Feedback principle by establishing a closed-loop system where the operational states of vehicle components are continuously monitored and fed back to update the surround view display in real-time. This feedback mechanism ensures the graphical representation accurately reflects the actual vehicle state, improving driver perception while maintaining simple operation through automated state detection and display updates

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent applies the Preliminary action principle by pre-defining the graphical representations and display configurations for various vehicle component states. The system is prepared in advance with multiple visual states for different component conditions (e.g., pre-programmed wheel rotation animations, light illumination patterns), allowing rapid switching between states without complex real-time rendering calculations, thus maintaining ease of operation while improving driver perception

Inventive Principle:
Principle #10Preliminary action
