Vehicle Control Device with Speech Communication for Remote Route Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack the ability for vehicle occupants to receive explanations from operators at a command center and convey their opinions regarding the selected travel route during autonomous or remote operation, especially in scenarios where a detour to sightseeing areas is desired.
Innovation Solution
A vehicle control device and system that includes a remote operation signal reception section, a control section for vehicle operation, and a speech communication device, enabling communication between the vehicle occupant and the operator at the command center, allowing for route suggestions and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote operation mode is used to enable flexible route selection by operator, then route flexibility is improved, but occupant's understanding of route selection and ability to provide feedback deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the speech communication device enables bidirectional communication between the operator and occupant. The occupant can provide feedback about their preferences (e.g., desire to visit sightseeing areas), and the operator can explain route selection reasons, creating a closed-loop information exchange that resolves the information loss problem while maintaining remote operation flexibility
Solution Approach 2:
The speech communication device acts as an intermediary between the operator and occupant, facilitating direct communication that bridges the information gap. This intermediary enables the occupant to understand the operator's route selection rationale and convey their preferences, thereby maintaining adaptability while preventing information loss
2Ease of operation
If autonomous driving mode is used for vehicle control, then ease of operation is improved, but ability to freely set complex routes deteriorates
Solution Approach 1:
The system combines multiple control modes (autonomous driving, remote operation, manual driving) into a universal vehicle control system. The speech communication device enables seamless transition between these modes and facilitates collaboration between autonomous systems and human operators, allowing the system to handle both simple autonomous operations and complex remote-controlled routes with occupant feedback

AI summary
A vehicle control device including: a remote operation signal reception section configured to be input with a remote operation signal based on an operation by an operator at a command center external to a vehicle; a control section configured to control the vehicle in a remote operation mode, based on the remote operation signal output from the command center, in a state in which remote operation of the vehicle from the command center side has been enabled; and a speech communication device configured to enable conversation between an occupant of the vehicle and an operator at the command center.
