Vehicle Movement Control Switching Under Server Communication Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face safety issues when communication failures occur between a server and a moving object, leading to abrupt interruptions in automatic movement control.
Innovation Solution
A movement control system that allows a moving object to perform first automatic movement control based on its own determination and second automatic movement control based on server instructions, switching to manual control if both are unavailable, and restricting or resuming server-led control based on communication reliability and normative ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the system relies on server-mediated second automatic movement control, then automation level and control precision are improved, but communication reliability becomes a critical vulnerability causing abrupt interruptions
Solution Approach 1:
The automatic movement control is segmented into two independent types: first automatic movement control (local autonomous control) and second automatic movement control (server-mediated control). This segmentation allows the system to operate with different automation levels depending on communication availability, preventing abrupt interruptions by switching between segments when communication fails.
Solution Approach 2:
The system dynamically changes the control mode parameter based on communication status. When communication with the server is available, the system operates in second automatic movement control mode with high automation. When communication fails, it switches to first automatic movement control mode, maintaining operational continuity and reliability.
2Reliability
If the system switches to first automatic movement control when server communication fails, then communication reliability is improved, but automation level and control precision deteriorate
Solution Approach 1:
The system prepares both first and second automatic movement control capabilities in advance as backup options. When server communication fails, the pre-prepared first automatic movement control acts as a cushion to prevent abrupt interruptions, maintaining control continuity even though the automation level is reduced.
3Reliability
If the system requires both first and second automatic movement control to be performable, then safety is improved, but system complexity increases
Solution Approach 1:
The control system dynamically adjusts its operational mode based on real-time conditions. The system monitors whether both first and second automatic movement control are performable and automatically switches between modes accordingly. This dynamic adaptation maintains safety requirements while managing system complexity through conditional logic rather than permanent dual-system operation.

AI summary
A movement control system includes: a server; and a moving object configured to perform first automatic movement control in which control contents are determined based on outside information and second automatic movement control in which the control contents are given by the server receiving the outside information. The moving object performs the second automatic movement control in a case where both the first automatic movement control and the second automatic movement control are performable. The moving object does not perform the second automatic movement control in a case where the second automatic movement control is performable but the first automatic movement control is unperformable.
