Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The general public has difficulty understanding the perspective of autonomous driving experiences through video demonstrations without the look and feel of being in a vehicle, and there is a need for a simulation that conveys the look and feel of autonomous driving without requiring an actual autonomous vehicle.
Innovation Solution
A virtual autonomous vehicle demonstration system that includes a display device showing video data and a steering wheel controlled via a control device to mimic the motion of an autonomous vehicle, using real-world driving data to synchronize video playback and wheel movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video demonstrations of autonomous vehicles are shown without physical vehicle presence, then accessibility and ease of operation are improved, but immersion and understanding of autonomous driving perspective deteriorate
Solution Approach 1:
The system creates a virtual copy of the autonomous vehicle experience by capturing real steering wheel movements and sensor data during actual autonomous driving, then replaying this data through a virtual reality interface. This allows viewers to experience autonomous driving perspective without physical vehicle presence, resolving the contradiction between accessibility and immersion.
Solution Approach 2:
A virtual reality intermediary system is introduced between the video demonstration and the viewer. This intermediary processes real driving data and presents it through immersive virtual visuals and haptic feedback, bridging the gap between simple video viewing and authentic driving experience.
2Reliability
If an actual autonomous vehicle is brought to trade shows for demonstration, then authenticity and trust are improved, but cost and complexity of deployment worsen
Solution Approach 1:
Instead of transporting physical autonomous vehicles to trade shows, the system creates accurate virtual copies using recorded sensor data, steering wheel movements, and environmental information. This virtual replication maintains authenticity while eliminating the logistical complexity of vehicle deployment.
Solution Approach 2:
The system extracts the essential driving experience elements (steering wheel data, sensor readings, visual feeds) from actual autonomous vehicle operations and separates them from the physical vehicle itself. This extraction allows demonstration without the vehicle, reducing deployment complexity while preserving trust-building authenticity.
3Device complexity
If traditional video playback is used without synchronized steering wheel movement, then device complexity is reduced, but engagement and educational value deteriorate
Solution Approach 1:
The system merges video playback with synchronized steering wheel movement control and virtual reality visuals into a unified demonstration system. By combining these elements and coordinating them through real driving data, the system enhances educational value without excessive complexity increase.
Solution Approach 2:
The system incorporates feedback loops where steering wheel position data from real autonomous driving is continuously referenced during playback to synchronize virtual visuals and haptic feedback with the recorded driving actions, creating an coherent and educational immersive experience.
Data Source
AI summary
A virtual autonomous vehicle (VAV) demonstration system including a display device, a steering wheel, and a control device. The display device displays a VAV demonstration application which includes video data and steering wheel data obtained from a real-world driving session of an autonomous vehicle. A steering wheel moves in correspondence with the steering wheel data and a video generated using the video data. A computing device controls the steering wheel and outputs the video for display on the display device. The steering wheel is controlled based on to the steering wheel data and a video control scheme for controlling playback of the video, and the steering wheel data is synchronized with frames of the video such that the steering wheel is caused, by the steering wheel control scheme, to move in correspondence with motion of the autonomous vehicle in the video.
