Automated Driving Control Device Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving vehicles face inefficiencies when communication with the operations management controller is lost, limiting their ability to adapt and utilize their functions effectively, especially when traveling along non-controlled routes without a predetermined schedule.
Innovation Solution
A control device for automated driving vehicles that switches between two modes: a first automated driving mode, where the vehicle travels along a controlled route with a scheduled operation, and a second automated driving mode, where it travels along a non-controlled route without a scheduled operation, allowing for flexible route selection and reduced communication requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving vehicles travel along controlled routes with predetermined schedules, then operational management and safety are improved, but operational flexibility and adaptability deteriorate
Solution Approach 1:
The system dynamically switches between two automated driving modes: a first mode for controlled routes with predetermined schedules and a second mode for non-controlled routes without schedules. This dynamic adaptability allows the vehicle to adjust its operation type based on route characteristics, thereby maintaining reliability on controlled routes while gaining flexibility when needed.
2Reliability
If automated driving vehicles communicate continuously with operations management controllers, then control and safety are improved, but communication dependency and operational independence deteriorate
Solution Approach 1:
The automated driving operation is segmented into two distinct modes: connected automated driving (first mode) requiring continuous communication with the operations management controller, and independent automated driving (second mode) operating without continuous communication. This segmentation allows the system to balance safety through connection when available with independence when communication is restricted or unavailable.
3Productivity
If automated driving vehicles are restricted to predetermined routes, then route management efficiency is improved, but route flexibility and functional utilization deteriorate
Solution Approach 1:
The system dynamically adjusts route selection based on operational needs, switching between controlled routes (first mode) that offer management efficiency and non-controlled routes (second mode) that provide flexibility. This allows the vehicle to utilize functions more efficiently by selecting appropriate route types for different operational scenarios.

AI summary
A control device for an automated driving vehicle has a first automated driving mode in which the automated driving vehicle, receiving a permission notice from an operations management controller, travels, according to automatic operation, along a controlled route managed by the operations management controller, in accordance with a traveling schedule provided from the operations management controller; and a second automated driving mode in which the automated driving vehicle travels, without a permission notice from the operations management controller, along a non-controlled route that is not managed by the operations management controller, according to automatic operation. The first automated driving mode and the second automated driving mode are switchable.
