Vehicle Transport Remote Operation to Reduce Occupant Anxiety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Occupants of vehicles experience anxiety during transportation by vehicle transportation devices when they cannot operate or instruct the device due to autonomous travel limitations.
Innovation Solution
A vehicle transportation system and method that allows remote operation of the vehicle transportation device via an in-vehicle system, enabling confirmation of remote operation requests and permitting such operations when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle transportation device operates autonomously without remote operation capability, then the transportation efficiency is improved and the device complexity is reduced, but the occupant experiences anxiety and cannot perform operations when needed
Solution Approach 1:
The system dynamically switches between autonomous operation mode and remote operation mode based on occupant needs. The remote operation acceptance signal enables the vehicle transportation device to transition from fully autonomous mode to a mode where remote operations from the vehicle are accepted, providing flexible adaptability without compromising overall transportation efficiency
Solution Approach 2:
A communication system acts as an intermediary between the vehicle and the vehicle transportation device. The communication device in the vehicle transmits operation signals to the vehicle transportation device, while the vehicle transportation device transmits remote operation acceptance signals back, enabling bidirectional communication that resolves the control capability issue without adding complex manual operation interfaces
2Ease of operation
If the vehicle transportation device accepts remote operations from the vehicle, then the occupant's control capability is improved, but the device complexity and communication requirements increase
Solution Approach 1:
The remote operation acceptance functionality is extracted as a separate communication feature. The vehicle transportation device includes a dedicated communication device that handles remote operation acceptance signals independently, separating this function from the core autonomous navigation system and reducing overall system complexity
Solution Approach 2:
The in-vehicle system serves itself by using its existing communication device to transmit remote operation signals. The vehicle's communication infrastructure is utilized for dual purposes: both standard vehicle operations and controlling the transportation device, eliminating the need for separate dedicated control interfaces
3Reliability
If the vehicle transportation device transmits remote operation acceptance signals continuously, then the information reliability is improved, but the energy consumption increases
Solution Approach 1:
The vehicle transportation device transmits remote operation acceptance signals periodically or at key operational moments rather than continuously. This periodic transmission maintains reliable communication for remote operation capability while significantly reducing energy consumption compared to continuous signal transmission

AI summary
The vehicle transportation system includes an in-vehicle system mounted on the vehicle, and a vehicle transportation device capable of communicating with the in-vehicle system and capable of transporting the vehicle by autonomous travel. The vehicle transportation device is configured to transmit a confirmation signal for confirming the presence or absence of a remote operation request to the in-vehicle system at the time of transportation of the vehicle, and permit remote operation from the inside of the vehicle when a request signal for remote operation is received from the in-vehicle system.
