Vehicle Platoon Remote Takeover for Emergency Travel Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in controlling the statuses of vehicles in a vehicle platoon, particularly when a target vehicle encounters an emergency or requires traveling intervention, and there is a need for flexible remote scheduling and management of the platoon.
Innovation Solution
A method and apparatus that enable remote control of vehicle platoon statuses through a network, allowing a target vehicle to initiate control of other vehicles in the platoon and transmit takeover requests to a remote control terminal, which can then control the target vehicle to enter a driving state and manage the platoon accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles of a vehicle platoon communicate with each other through a near-field direct communication interface and complete driving as a platoon and management independently, then the platoon can operate autonomously without external intervention, but the system lacks the capability to perform remote control and flexible scheduling when a target vehicle encounters an emergency or requires traveling intervention
Solution Approach 1:
The patent introduces a remote control terminal as an intermediary device that enables remote control of vehicle platoon operations. The terminal communicates with the target vehicle through a network interface, acting as a mediator between the remote operator and the vehicle's control systems. This allows emergency intervention and flexible scheduling without requiring direct modification of the vehicle's core control architecture.
Solution Approach 2:
The remote control terminal is designed to perform multiple functions including emergency control, traveling intervention, and general platoon management. By creating a multi-functional control interface, the system achieves adaptability for various scenarios without requiring separate specialized systems for each function.
2Reliability
If the vehicle platoon operates with independent near-field communication between vehicles, then the communication reliability within the platoon is maintained, but the system cannot respond to external emergencies or perform remote scheduling interventions
Solution Approach 1:
The communication system is segmented into two independent channels: near-field direct communication for routine platoon operations and remote control, and network-based communication for remote terminal access. This segmentation allows the system to maintain reliable autonomous operation while simultaneously enabling external intervention capabilities without compromising either function.
Solution Approach 2:
The remote control terminal serves as an intermediary that bridges the gap between independent platoon operations and external emergency response requirements. It provides a controlled interface for external communication without disrupting the established reliable near-field communication protocols within the platoon.
3Ease of operation
If a target vehicle initiates control of other vehicles in the platoon and transmits takeover requests to a remote control terminal, then flexible remote scheduling is enabled, but the control system complexity and communication overhead increase
Solution Approach 1:
The target vehicle is pre-configured with the capability to initiate control actions and transmit takeover requests to the remote terminal. By establishing these preliminary control interfaces and authorization mechanisms in advance, the system enables flexible remote scheduling operations without requiring complex real-time decision-making architectures.

AI summary
A method for controlling travelling of a vehicle platoon includes: establishing, by a target vehicle of the vehicle platoon, a network connection with a remote control terminal; determining, by the target vehicle, that the target vehicle is to be remotely taken over; initiating, by the target vehicle, control of statuses of vehicles of the vehicle platoon other than the target vehicle; transmitting, by the target vehicle, a takeover request to the remote control terminal, controlling, by the remote control terminal, the target vehicle to enter a driving state; and receiving, by the target vehicle, a takeover confirmation message transmitted by the remote control terminal, wherein the vehicles include a leading vehicle (LV) and a following vehicle (FV) of the LV.
