Vehicle Assembly Stop Control for Unmanned Driving Resumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face issues with vehicles restarting during assembly, leading to potential failure in part assembly when unmanned driving is resumed.
Innovation Solution
A server device with a command generation and transmission system that detects when a vehicle is stopped for assembly, halting the running command and enabling resumption only after assembly completion, using sensors and assembly robot information to ensure accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle runs by unmanned driving continuously, then productivity is improved, but the risk of assembly failure increases when the vehicle stops for part assembly
Solution Approach 1:
The system performs preliminary detection of the stopping state before assembly occurs, and proactively stops the running command generation and transmission in advance. This prevents the vehicle from moving during assembly operations, ensuring assembly reliability while maintaining continuous unmanned driving productivity.
2Reliability
If the running command is stopped during assembly, then assembly reliability is improved, but the response time to resume driving increases
Solution Approach 1:
The system establishes a feedback mechanism where the assembly detection unit continuously monitors assembly completion status and immediately notifies the command generation unit. When assembly is detected as complete, the running command generation and transmission are automatically resumed without manual intervention, minimizing time loss while ensuring assembly reliability.
3Measurement precision
If multiple detection methods are used to detect assembly completion, then detection precision is improved, but device complexity increases
Solution Approach 1:
The assembly detection unit is designed with multi-functionality to detect various assembly completion indicators through a single integrated system. It can detect arm unit position, gripping state, and other assembly parameters universally, improving detection precision without proportionally increasing device complexity.

AI summary
A server device includes a command generation unit that generates a running command for controlling running of a vehicle by unmanned driving; a command transmission unit that controls transmission of the running command to the vehicle; a stopping detection unit that detects that the vehicle has been stopped at an assembly position where a part is assembled onto the vehicle; and a stopping unit that performs at least one of a process of stopping the generation of the running command by the command generation unit, a process of stopping the transmission of the running command by the command transmission unit, and a process of transmitting to the vehicle a deactivation command that disables the running command, when it is detected that the vehicle has been stopped at the assembly position.
