Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-based mobility systems face challenges in stable controller updates due to battery discharge risks during updates when the vehicle is not started, leading to interrupted or difficult updates.
Innovation Solution
A mobility system and update management method that determine the order of controller updates and battery power supply based on battery state, importance, and vehicle driving conditions, using multiple auxiliary batteries to ensure stable updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If controller updates are performed when the vehicle starting is turned off to avoid interference with driving, then update stability is improved, but battery discharge risk increases causing update interruption
Solution Approach 1:
The update management apparatus checks the battery charge level before initiating a controller update. When the charge level is below a predetermined threshold, the system performs preliminary charging of the battery before allowing the update to proceed, thereby preventing update interruption due to battery discharge.
Solution Approach 2:
The system dynamically adjusts update execution based on real-time battery state monitoring. The update management apparatus continuously monitors battery charge levels and makes dynamic decisions about whether to proceed with, delay, or charge the battery before updating, adapting the update process to current energy availability.
2Productivity
If multiple controllers are updated simultaneously to improve efficiency, then productivity increases, but battery power consumption increases causing update failure
Solution Approach 1:
The update management apparatus divides multiple controller updates into separate sequential operations rather than simultaneous execution. Each controller update is managed as an independent task that consumes battery power, allowing the system to monitor and control power consumption for each individual update operation.
Solution Approach 2:
The system changes operational parameters by adjusting the number of concurrent update operations based on available battery charge levels. When battery charge is sufficient, more controllers can be updated; when charge is low, fewer controllers are updated or charging is performed first, dynamically adapting update throughput to energy availability.
3Loss of time
If controller updates are prioritized over battery charging to meet update deadlines, then update timeliness is improved, but battery charge level decreases causing future update failures
Solution Approach 1:
The update management apparatus performs preliminary battery charging before initiating controller updates when the battery charge level is below a predetermined threshold. This ensures sufficient power is available for the update operation while still meeting update deadlines by planning and executing charging in advance.
Solution Approach 2:
The system builds up a cushion of battery charge before updates by performing charging operations in advance when power is available. This beforehand cushioning of energy reserves prevents future update failures due to insufficient power while maintaining update schedule adherence.
