Vehicle Control Device Dynamic Update Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle ECU program updates often require the vehicle to be stopped, but the optimal update time varies by user, leading to inefficiencies as pre-set update dates may not align with vehicle usage patterns.
Innovation Solution
A control device that acquires a vehicle's schedule to estimate when the vehicle is not in use, generating a customized update date and time based on the usage situation, allowing for more flexible and user-specific program updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pre-set update date and time is used for ECU program updates, then the update process is simple and systematic, but the update may occur when the vehicle is in use, causing inconvenience and potential safety issues
Solution Approach 1:
The patent applies dynamics by transitioning from a static, fixed update schedule to a dynamic update schedule that adapts based on vehicle usage patterns. The system continuously monitors whether the vehicle is in use and adjusts the update timing accordingly, allowing updates to be performed during periods when the vehicle is not being used, thus resolving the contradiction between systematic update processes and user convenience
Solution Approach 2:
The system implements feedback by monitoring vehicle usage status and using this information to determine appropriate update timing. The control device receives information about whether the vehicle is currently in use and adjusts the update schedule based on this feedback, ensuring updates occur only when the vehicle is available, thereby maintaining both update efficiency and user convenience
2Reliability
If the vehicle is stopped for program updates, then the update can be performed safely, but the user loses vehicle availability during the update period
Solution Approach 1:
The system applies preliminary action by proactively monitoring vehicle usage patterns and identifying future time periods when the vehicle is not in use. It schedules updates in advance during these identified windows, ensuring that updates are performed safely when the vehicle is available while minimizing the impact on user convenience. This allows the system to prepare and execute updates during optimal times without requiring the user to manually stop the vehicle
3Productivity
If updates are performed during vehicle operation, then vehicle availability is maintained, but the update process may be interrupted or cause safety issues
Solution Approach 1:
The system uses feedback mechanisms to continuously monitor vehicle operation status and prevent updates from being initiated when the vehicle is in use. By receiving real-time information about vehicle usage, the control device ensures that updates are only scheduled during periods when the vehicle is stationary and available, thereby maintaining both vehicle availability during normal operation and update reliability during maintenance periods

AI summary
Disclosed is a control device that changes control content of control means mounted in a vehicle, including: schedule acquisition means for acquiring a schedule relating to the vehicle; and change date and time generation means for estimating a time when the vehicle is not in use on the basis of the schedule acquired by the schedule acquisition means, and for generating and outputting change date and time when the control content is changed, according to the time.
