Vehicle ECU Update Control System for Power and Downtime Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in efficiently updating Electronic Control Units (ECUs) without causing unintended downtime or battery power consumption, particularly when users need immediate vehicle access or when important updates are overlooked.
Innovation Solution
A control system that automatically updates ECUs when the vehicle is stationary and the ignition is off, allowing users to postpone updates and ensuring updates are performed only when the vehicle is in a predetermined state, thereby minimizing downtime and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ECU is updated automatically without user notification, then the update reliability is improved, but the user convenience deteriorates due to unintended downtime
Solution Approach 1:
The system implements feedback by notifying the user of the scheduled update and accepting cancellation input. The notification control unit displays update information to the user, and the instruction acquisition control unit receives user input to cancel or confirm the update, creating a feedback loop that resolves the contradiction between automatic updates and user convenience
Solution Approach 2:
The system performs preliminary action by scheduling the update for a predetermined time after power-off and providing advance notification to the user. This allows the update to be prepared and scheduled before execution, giving the user opportunity to review and cancel if needed, thus maintaining both reliability and user convenience
2Productivity
If the ECU update is performed immediately after power-off, then the productivity is improved, but the loss of time increases due to unexpected downtime
Solution Approach 1:
The system performs preliminary action by scheduling the update for execution after a predetermined time elapses following power-off. This timing allows the user to return to the vehicle and potentially cancel the update, preventing unexpected downtime while maintaining update efficiency through automated scheduling
3Productivity
If the ECU update is performed automatically, then the productivity is improved, but the use of energy increases due to battery power consumption during user absence
Solution Approach 1:
The system performs preliminary action by scheduling the update for execution after a predetermined time following power-off. This timing strategy allows the update to be ready to execute efficiently while minimizing battery consumption by only operating during periods when the vehicle is confirmed to be unattended
Solution Approach 2:
The system implements self-service by automatically managing the update execution based on predetermined conditions and user input stored in memory. Once the update is scheduled and conditions are met, the system autonomously executes the update without requiring continuous user presence or intervention, reducing energy consumption

AI summary
Provided is a control system, including: a mobile object control unit configured to control a mobile object; an update control unit configured to receive an update program of the mobile object control unit from an external apparatus, and update the mobile object control unit with the update program; an instruction acquisition control unit configured to perform control to acquire a user instruction indicating that the update of the mobile object control unit with the update program is not executed; and a determination unit configured to determine whether an updatable condition is satisfied, which is a determination condition for determining the mobile object is in an updatable state or not, based on at least either of a driveline state of the mobile object or an opening or closing state of a door installed in the mobile object.
