VR Remote Vehicle Control for Immersive Autonomous Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles, especially at Level 5, face challenges in navigating unknown environments or situations without a human driver, as conventional remote control systems rely on 2D visualizations and generic computer controls, which lack immersion and natural control capabilities, leading to safety and operational inefficiencies.
Innovation Solution
The implementation of virtual reality (VR) technology to create an immersive virtual environment for remote operators, allowing them to control autonomous vehicles or objects through a VR headset, using sensor data and vehicle state information to calibrate controls and provide a more intuitive and natural control experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If 2D visualizations are used on 2D displays for remote control, then device complexity is reduced, but immersion and control precision deteriorate
Solution Approach 1:
The patent transitions from 2D display visualizations to a 3D virtual reality environment. The remote operator wears a VR headset that renders three-dimensional representations of the autonomous vehicle and its surroundings, allowing natural head movements and spatial awareness. This dimensional upgrade provides immersive depth perception and intuitive spatial relationships that 2D displays cannot achieve, directly improving remote control safety while maintaining manageable system complexity through software-based VR rendering.
Solution Approach 2:
The system creates a virtual copy of the autonomous vehicle's environment and controls within the VR headset. Sensor data from the real vehicle is used to generate an accurate virtual representation, including virtual cameras positioned on the vehicle and virtual control components that mirror the actual vehicle controls. This virtual copying allows the remote operator to interact with a faithful replica of the driving environment, enhancing immersion and control precision without requiring physical presence in the vehicle.
2Device complexity
If generic computer controls (keyboard, mouse, joystick) are used, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent implements virtual control components within the VR environment that are direct copies of actual vehicle controls. The remote operator interacts with a virtual steering wheel, accelerator, and brake pedals that are rendered in the VR scene. These virtual controls are positioned and designed to match the physical vehicle's control layout, creating a familiar and intuitive interface. The operator's hand movements and forces applied to the virtual controls are directly mapped to the real vehicle's control systems, providing natural and precise operation without the learning curve associated with generic computer controls.
3Loss of information
If 2D visualizations are used, then information presentation is simplified, but measurement precision and situational awareness deteriorate
Solution Approach 1:
The system replaces 2D flat visualizations with 3D spatial representations rendered in the VR headset. Virtual cameras positioned on the autonomous vehicle capture and display the environment from multiple perspectives simultaneously, including front, rear, and side views. The virtual environment preserves accurate spatial relationships, distances, and depths of objects around the vehicle. This three-dimensional presentation maintains complete information about the driving environment while providing precise depth perception and spatial awareness that 2D displays cannot achieve, enabling the remote operator to accurately judge object locations and distances.
Data Source
AI summary
In various examples, at least partial control of a vehicle may be transferred to a control system remote from the vehicle. Sensor data may be received from a sensor(s) of the vehicle and the sensor data may be encoded to generate encoded sensor data. The encoded sensor data may be transmitted to the control system for display on a virtual reality headset of the control system. Control data may be received by the vehicle and from the control system that may be representative of a control input(s) from the control system, and actuation by an actuation component(s) of the vehicle may be caused based on the control input.
