Vehicle Control Handover Between Local Drivers and Teleoperators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transfer of control between local operators and remote operators of road vehicles must be executed precisely to ensure safe operation, as existing technologies lack effective methods for seamless transitions and real-time monitoring of vehicle states and operator performance.
Innovation Solution
A system that allows drivers to request control transfer to teleoperators, with a pool of teleoperators selected based on experience and suitability, using wireless communication networks for bi-directional data transmission, including imaging and drive state information, and real-time monitoring to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control is transferred from local operator to remote teleoperator, then vehicle safety is improved by reducing operator fatigue and errors, but system complexity increases due to need for communication networks and coordination protocols
Solution Approach 1:
A server acts as an intermediary between the vehicle and teleoperator stations, managing control transfers and coordinating communication. The server receives requests from either local operators or teleoperators, processes the transfer protocol, and ensures safe handover of vehicle control, thereby reducing direct system complexity while maintaining safety
Solution Approach 2:
The control system is segmented into distinct functional components: local operator controls, remote teleoperator stations, and a central server. This segmentation allows each component to operate independently with well-defined interfaces, improving reliability through modular design while managing overall system complexity
2Measurement precision
If real-time monitoring and data transmission are implemented, then operator performance and vehicle state are better monitored for safety, but information loss and communication delays may occur
Solution Approach 1:
The system implements bidirectional feedback loops where the vehicle continuously transmits state data (position, speed, sensor information) to the server, and the server provides feedback commands to both local operators and teleoperators. This ensures real-time monitoring while maintaining data accuracy through continuous verification and correction
Solution Approach 2:
The system performs preliminary actions by pre-establishing communication channels and data transmission protocols before control transfer occurs. Vehicle state data is continuously buffered and validated in advance, ensuring that no critical information is lost during the transition period
3Ease of operation
If control transfer protocol is simplified, then ease of operation is improved, but reliability may be compromised due to insufficient safety checks
Solution Approach 1:
The system performs preliminary safety checks and validations before executing control transfer. The server verifies vehicle state, operator credentials, and environmental conditions in advance, then presents a simplified interface to operators for final confirmation, balancing simplicity with thorough safety verification
Solution Approach 2:
The control transfer system automatically manages many safety checks and coordination tasks without requiring manual intervention from operators. The server autonomously verifies conditions, coordinates with relevant parties, and executes the transfer protocol, simplifying the operator's role while maintaining high reliability through automated safety mechanisms

AI summary
A vehicle is configured for local operation by an on-board human operator or remote operation by a remote human operator (or teleoperator) via a computer system in communication with the vehicle. A local human operator may request that a remote human operator take operational control of the vehicle, and a bi-directional communication channel between the computer system and the vehicle is established. The remote human operator is selected based on a drive state of the vehicle, any attributes of the local human operator or the remote human operator. When the vehicle violates one or more standards under operational control of the local human operator, transfer of the operational control is recommended to the local human operator. When the vehicle violates one or more standards under the operational control of a remote human operator, the operational control of the vehicle is transferred to another remote human operator.
