Hologram Steering Wheel Interface for Autonomous Driving Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous driving and automatic parking modes, users face difficulty in manipulating the steering wheel's buttons due to automatic control, which hampers convenience and visibility.
Innovation Solution
A hologram display control apparatus that projects a hologram image of the steering wheel's manipulating device onto a predefined area, recognizes button operations, and transmits control signals to the vehicle's driving devices, allowing users to interact with the system through a hologram interface.

Engineering Contradiction Analysis
1Extent of automation
If the steering wheel is automatically manipulated under autonomous driving control, then the autonomous driving function is improved, but the ease of manipulating the steering wheel buttons deteriorates
Solution Approach 1:
The patent creates a virtual copy of the steering wheel manipulating unit as a hologram image that can be independently controlled. This virtual manipulating unit allows users to interact with buttons and controls without physically rotating the actual steering wheel, thereby maintaining ease of operation during autonomous driving mode while preserving full automation capability.
Solution Approach 2:
The hologram image serves as an intermediary interface between the user and the vehicle's control systems. Instead of directly manipulating the physical steering wheel during autonomous mode, users interact with the virtual holographic representation, which then translates these interactions into appropriate control signals, resolving the conflict between automation and manual control accessibility.
2Extent of automation
If the steering wheel is automatically manipulated, then the autonomous driving function is improved, but the visibility of button manipulation deteriorates
Solution Approach 1:
The patent creates a virtual copy of the steering wheel manipulating unit as a hologram image that can be independently controlled. This virtual manipulating unit allows users to interact with buttons and controls without physically rotating the actual steering wheel, thereby maintaining ease of operation during autonomous driving mode while preserving full automation capability.
Solution Approach 2:
The hologram technology provides visual feedback through light and color changes that indicate which buttons are being manipulated or are active. This visual information compensation ensures that users can see and understand the manipulation state even when the physical steering wheel is not being manually rotated, addressing the visibility information loss during autonomous mode.
3Ease of operation
If a hologram image of the manipulating device is projected, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the hologram projection capability into the existing vehicle's manipulating unit, allowing the same hardware to serve multiple functions: normal physical manipulation during manual driving mode and virtual holographic manipulation during autonomous driving mode. This multi-functionality approach reduces the need for completely separate systems, thereby mitigating the increase in device complexity.
