Solution Overview

Problem

Existing vehicle information display systems fail to provide an adaptive and intuitive representation of the driving situation, lacking feedback to the driver through dynamic changes in graphical objects based on vehicle acceleration.

Innovation Solution

The method involves dynamically changing the representation of graphical objects on a vehicle's display device in response to detected acceleration, using three-dimensional perspective or autostereoscopic pivoting movements that align with the vehicle's acceleration axes, allowing for intuitive visualization of the driving situation without requiring special viewing aids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If static graphical objects are displayed on the vehicle display, then the display system is simple and easy to operate, but the driver receives no feedback on the driving situation

Engineering Contradiction:
Improvefeedback on driving situationVSAvoiddisplay system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transforming static graphical objects into dynamic representations that pivot and change orientation based on detected vehicle acceleration. The graphical objects respond to acceleration inputs by rotating and repositioning themselves, providing real-time feedback on the driving situation without requiring complex additional hardware.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by using acceleration sensors to detect vehicle motion and automatically adjusting the graphical object representation accordingly. The system closes the feedback loop by taking sensor data about vehicle acceleration and using it to modify the display output, giving the driver intuitive visual feedback about the vehicle's dynamic state.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If traditional 2D display representations are used, then the display device is simple, but the driver lacks intuitive understanding of the driving situation

Engineering Contradiction:
Improveintuitive visualizationVSAvoidgraphical representation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies dimensionality change by transitioning from flat 2D graphical representations to pseudo-3D representations that utilize depth perception through perspective projection. The graphical objects are rendered with three-dimensional properties and pivot in 3D space, creating a more intuitive visual experience that helps drivers understand the driving situation better.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements parameter changes by dynamically modifying multiple parameters of the graphical objects including their orientation, position, scale, and perspective based on acceleration sensor data. These parameter changes occur in real-time as the vehicle accelerates, providing intuitive visual feedback about the driving situation.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If acceleration-based dynamic display changes are implemented, then intuitive feedback on driving situation is provided, but the processing requirements and system complexity increase

Engineering Contradiction:
Improvedriving situation feedbackVSAvoidprocessing and display system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent uses an intermediary approach by introducing a control device that acts as a mediator between the acceleration sensor and the display device. This control device processes the acceleration data and generates appropriate graphical object transformations, simplifying the overall system architecture while still providing sophisticated dynamic feedback.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This approach provides the driver with real-time, intuitive feedback on the vehicle's acceleration and direction, enhancing situational awareness through adaptive and engaging graphical representations that align with the vehicle's movements, improving the overall driving experience.

Implementation Method 1

the acceleration of the vehicle is detected by means of an acceleration sensor

Methodology Applied
Scientific EffectAcceleration measurement: Accelerometer

Implementation Method 2

the graphic object is displayed in three-dimensional perspective pivoted about an axis when the display is changed

Methodology Applied
Scientific EffectThree-dimensional perspective: Parallax

Implementation Method 3

the graphic object is displayed autostereoscopically pivoted about an axis when the display is changed. In this case, in contrast to the perspective representation, one eye of the viewer sees a slightly different image than the other eye, so that a real three-dimensional representation is achieved

Methodology Applied
Scientific EffectAutostereoscopy: Parallax

Implementation Method 4

The mask is a wavelength-selective filter mask, for example. This filter specifies the light propagation directions of the individual sub-pixels of the display by covering or filtering

Methodology Applied
Scientific EffectWavelength-selective filtering: Filter (optical)
