Power Converter Program Activation Without Unintended Device Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in preventing unintended power supply to electric devices driven by power converters during the installation or activation of power converter programs.
Innovation Solution
A mobile object control device and method that execute the installation or activation of a power converter program in a state where input voltage is not applied to the electric device driven by the power converter, ensuring that the power converter is controlled without inadvertently powering the electric device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power converter program installation or activation is performed while input voltage is applied to the electric device, then the program can be installed/activated, but unintended power supply to the electric device may occur causing safety issues
Solution Approach 1:
The control device determines whether the electric device is in a state allowing program installation before actually installing or activating the power converter program. This preliminary check ensures that the device is in a safe state (no unintended power supply risk) before the program operation commences, thereby resolving the contradiction between safety and operational convenience
2Reliability
If the controller checks the state of the electric device before program installation, then safety is improved, but the control process becomes more complex
Solution Approach 1:
The control device integrates multiple functions into a single determination process: it simultaneously checks whether input voltage is applied to the electric device and whether the device is in a state allowing program installation. This multi-functional determination unit consolidates what could be separate complex checks into one unified process, maintaining safety while minimizing added complexity

AI summary
A mobile object control device includes a controller. The controller is configured to receive an instruction to execute an installation or activation of a power converter program for controlling a power converter that is installed in a mobile object, execute the installation or activation of the power converter program based on the instruction when input voltage is not applied to an electric device that is driven by the power converter, and stop power supply to the electric device and then execute the installation or activation of the power converter program based on the instruction when the input voltage is applied to the electric device.
