VR Remote Control Interface for Autonomous Vehicle Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in navigating unknown or hazardous environments without direct human control, particularly at higher autonomy levels where no driver is present, as conventional remote control methods using 2D visualizations and generic computer controls lack immersion and natural control capabilities.
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 other objects through a VR headset, using sensor data and vehicle state information to generate a realistic and interactive control interface that mimics the physical environment and vehicle controls.
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 effectiveness deteriorate
Solution Approach 1:
The patent transitions from 2D display visualizations to 360-degree immersive virtual reality environments. The remote operator wears a VR headset that provides three-dimensional spatial awareness and panoramic views of the autonomous vehicle's surroundings, enabling more intuitive control decisions while maintaining relatively simple system architecture through standardized VR hardware integration.
2Adaptability or versatility
If generic computer components (keyboard, mouse, joystick) are used for control, then adaptability to different vehicles is improved, but control naturalness and smooth operation deteriorate
Solution Approach 1:
The patent implements virtual representations of actual vehicle controls (steering wheel, accelerator, brake pedals) within the VR environment. These virtual controls are calibrated to match the physical vehicle's control characteristics, providing familiar and intuitive control mappings. The system copies the essential control mechanics from the autonomous vehicle to the remote operator's interface, enabling natural control operations while maintaining adaptability through software calibration.
3Loss of information
If 2D visualizations are used, then information presentation simplicity is improved, but information completeness and digestibility deteriorate
Solution Approach 1:
The patent employs 360-degree panoramic views and three-dimensional spatial representations within the VR environment to display vehicle state information. Multiple camera feeds, sensor data, and vehicle status indicators are integrated into the immersive environment, providing comprehensive information about the vehicle's surroundings, position, and operational state without overwhelming the operator through cluttered 2D displays.
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.
