Vehicle Telematics Remote Reflash Battery Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular telematics systems lack an efficient method to notify and prepare electric vehicles for remote reflash events, ensuring sufficient battery charge and system readiness, which can lead to incomplete updates and operational issues.
Innovation Solution
The telematics service provider communicates with the vehicle's telematics unit to schedule and prepare for remote reflash events by instructing the vehicle to increase its battery charge level during drive cycles, ensuring a sufficient state of charge for the update process and providing confirmation of completion, with the option to notify users or emergency services if the post-reflash charge is inadequate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle undergoes remote reflash event without sufficient battery charge, then software update can be performed, but the vehicle may experience operational issues or incomplete updates
Solution Approach 1:
The system performs preliminary battery charge assessment before initiating the remote reflash event. The telematics unit checks the battery state of charge and compares it against a threshold value, only allowing the update to proceed if sufficient charge is available. This preliminary action prevents incomplete updates and operational issues by ensuring energy sufficiency before the update begins.
2Reliability
If the vehicle waits for sufficient battery charge before remote reflash event, then update reliability improves, but update timing and productivity are delayed
Solution Approach 1:
The system implements a feedback mechanism where the telematics unit continuously monitors battery state of charge and communicates this information to the remote server. The server uses this feedback to determine whether to proceed with or postpone the scheduled reflash event. This feedback loop ensures updates are performed reliably while minimizing unnecessary delays by only waiting when truly necessary.
3Reliability
If the system monitors and manages battery charge for remote reflash events, then update success rate improves, but system complexity increases
Solution Approach 1:
The telematics unit autonomously performs battery charge level monitoring, threshold comparison, and update eligibility determination without requiring complex external management systems. The unit independently assesses whether the vehicle is ready for the reflash event and communicates this status to the server, simplifying the overall system architecture while maintaining high update success rates.

AI summary
Implementations of the present disclosure contemplate utilizing the communicative connections between a telematics service provider (TSP) and a telematics unit in a vehicle to schedule a remote reflash event, issue instructions to the vehicle to prepare for the remote reflash event, and to administer the remote reflash event. A TSP may determine that the vehicle is presently running software for which an update is desirable. Thereafter, the TSP may transmit instructions to the vehicle to make preparations for the remote reflash event. In some implementations, the instructions may cause the vehicle to obtain a higher level of battery charge during its next drive cycle or charging event in anticipation of the remote reflash event.
