Vehicle Driving Support Training via AR/VR Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot sufficiently understand the support functions of a vehicle due to the lack of a simulated experience using an actual vehicle.
Innovation Solution
A driving support device with an operation unit, driving control unit, storage unit, and notification unit that switches between a travel mode and an explanation mode, providing explanations of driving support functions through augmented, mixed, or virtual reality, allowing drivers to learn and understand these functions without affecting vehicle travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user performs simulated experience using a client terminal and server, then the user can experience support functions virtually, but the user cannot sufficiently understand the support function
Solution Approach 1:
The patent creates a virtual copy of the actual vehicle operation environment through VR/AR technology. The system replicates the operation units, display units, and support function behaviors of the actual vehicle in a virtual space, allowing users to interact with and learn about support functions through this immersive copy rather than a conventional 2D interface.
Solution Approach 2:
The VR/AR device serves as an intermediary between the user and the actual vehicle system. It mediates the interaction by capturing operation signals from the user, transmitting them to the vehicle control unit, and simultaneously providing visual feedback through virtual images that explain support function operations, thereby bridging the gap between virtual simulation and actual vehicle behavior.
2Loss of information
If the notification unit provides explanation while the vehicle travels, then the driver cannot focus on both driving and learning, but if explanation is provided separately, then the driver cannot learn while operating the actual vehicle
Solution Approach 1:
The patent transitions the explanation delivery from a conventional 2D display to a 3D immersive virtual reality environment. By presenting explanatory content in a virtual space that overlays or replaces the actual vehicle view, the system provides comprehensive explanations without competing for the driver's peripheral attention, as the information is delivered in the driver's central field of view within the VR/AR interface.
Solution Approach 2:
The system dynamically switches between different operational modes: in the first operation mode, the vehicle travels normally with support functions active; in the second operation mode, the vehicle remains stationary or moves minimally while the VR/AR device provides detailed explanations and allows operation practice. This dynamic mode switching enables the driver to learn thoroughly without compromising driving safety.
3Ease of operation
If the driver operates the operation unit of the actual vehicle during explanation, then the operation is reflected in vehicle travel, but the driver cannot learn without affecting actual travel
Solution Approach 1:
The control unit dynamically switches between two operational modes. In the first mode, normal driving operations are permitted and reflected in vehicle travel. In the second mode, which is activated during explanation sessions, the vehicle's travel response to operation unit inputs is restricted or decoupled, allowing the driver to practice operations and receive explanations without the operations directly affecting actual vehicle movement, thereby ensuring safety while enabling hands-on learning.
Solution Approach 2:
The system creates a virtual replica of the operation units and their effects in the VR/AR environment. When the driver operates the physical operation unit, the system captures the input and reflects it in the virtual environment where explanations are provided, while optionally decoupling the direct connection to actual vehicle travel during explanation mode. This allows the driver to practice operations in a safe virtual copy without compromising real-world safety.

AI summary
A driving support device includes an operation unit configured to receive an operation of a driver related to driving support of a vehicle; a driving control unit configured to execute the driving support based on the operation of the driver; a storage unit configured to store an explanation of the driving support corresponding to the operation unit; a notification unit configured to provide the explanation of the driving support to the driver through any one of augmented reality, mixed reality and virtual reality; and a control unit connected to the driving control unit, the notification unit, and the storage unit, configured to switch between a travel mode and an explanation mode and to operate in a mode switched.
