Vehicle Terminal Software Update Battery Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle software updates often fail due to battery discharge issues, as the battery capacity decreases over time, leading to insufficient power for updates after a certain period, which affects customer convenience and the ability to perform updates.
Innovation Solution
A vehicle terminal system that includes a communication device for wireless communication with CCS and CDN servers, a storage for previously installed software, and a processing device that updates software based on differential software sizes and battery consumption, allowing updates only when the battery state of charge is sufficient and optimizing update times according to parking patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software updates are performed using battery power when the vehicle is turned off, then customer convenience is improved, but battery discharge occurs leading to insufficient power for updates as the vehicle ages
Solution Approach 1:
The system performs preliminary actions by checking the battery's state of charge before initiating a software update. It calculates the required power based on differential software size and compares it with the current battery capacity. This preliminary assessment ensures that updates only proceed when sufficient power is available, preventing battery discharge issues while maintaining update convenience.
Solution Approach 2:
The system dynamically adjusts update execution based on real-time battery state. It continuously monitors the state of charge and makes adaptive decisions about whether to proceed with updates. This dynamic approach allows the system to optimize between customer convenience and battery preservation by responding to changing battery conditions.
2Reliability
If the system checks battery state before updates, then update success rate is improved, but system complexity increases
Solution Approach 1:
The system performs self-service by autonomously checking battery state, calculating power requirements, and making update decisions without requiring external intervention. The processing device automatically retrieves battery information, computes the state of charge, compares it with required power levels, and determines update feasibility. This self-service mechanism improves reliability while minimizing the need for additional complex control systems.
