Mobile Object Control System Update via Dynamic Communication Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face delays in applying important updates due to reliance on wireless LAN communication, which can be unavailable in certain situations, leading to prolonged periods where critical updates are not applied.
Innovation Solution
The system allows the server to transmit communication manner change information to the vehicle, enabling updates specified for wireless LAN to be received via mobile communication, ensuring timely application of important updates by allowing alternative communication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system relies on wireless LAN communication for updates, then power consumption is reduced and data transmission efficiency is improved, but update timeliness deteriorates when wireless LAN is unavailable
Solution Approach 1:
The system dynamically switches communication methods based on availability. When wireless LAN is unavailable, the system automatically transitions to mobile communication to receive updates, ensuring update timeliness is maintained without being stuck in a static communication mode
Solution Approach 2:
The system changes the communication parameter from wireless LAN to mobile communication when necessary. This parameter switching allows the system to adapt to different network environments and ensures updates can be received timely regardless of which communication method is available
2Adaptability or versatility
If the system uses only wireless LAN for updates, then communication infrastructure requirements are simplified, but system adaptability to different environments deteriorates
Solution Approach 1:
The communication system is designed with multi-functionality, supporting both wireless LAN and mobile communication methods. This universal approach allows the system to adapt to different environments and communication availability scenarios without requiring separate dedicated systems for each method
3Productivity
If the system waits for wireless LAN availability to apply updates, then data transmission efficiency is optimized, but productivity of update application deteriorates
Solution Approach 1:
The system performs preliminary actions by checking for update availability and preparing to receive updates through alternative communication methods. When mobile communication is available, the system proactively initiates update reception without waiting for wireless LAN, reducing the waiting time and improving update application speed

AI summary
A control system comprises a mobile object control unit for controlling a mobile object; an update control unit for controlling reception of an update program of the mobile object control unit from a server and controlling update of the mobile object control unit by the program; an acquisition unit for acquiring reception information indicating a communication manner for receiving from the server for each program; and a communication control unit for controlling receiving the program from the server, based on the reception information, wherein the acquisition unit is for, when both a first update program and a second update program received after update by the first update program is executed have not been received, acquiring information about change of reception information of the first update program, and the communication control unit is for controlling receiving the first update program based on the information about change acquired by the acquisition unit.
