Connected Car Modem Standby Scheduling for Battery Drain Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected cars face battery drain issues due to modems operating in standby mode, limiting user control over remote service management, leading to potential dead batteries when not actively used.
Innovation Solution
A method and system that manage remote service standby time by setting and ending modem standby modes based on user settings, customer terminal information, and CCS center checks, allowing for efficient battery resource management through scheduled shut-downs and wake-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the modem operates in standby mode to enable remote service, then remote service availability is improved, but battery consumption increases
Solution Approach 1:
The modem operates in periodic standby mode rather than continuous operation. The system checks for remote service requests at intervals and activates the modem only when needed, then shuts it down after a predetermined standby time expires. This periodic operation pattern reduces overall battery consumption while maintaining remote service availability when required.
2Duration of action of moving object
If the modem standby time is extended to ensure service availability, then remote service accessibility is improved, but battery drain increases
Solution Approach 1:
The system dynamically adjusts the modem standby time parameter based on operational conditions. A predetermined standby time is set, and the modem is shut down when this time expires. This parameter control allows the system to optimize between service availability and energy conservation by adjusting how long the modem remains active in standby mode.
3Device complexity
If the customer cannot directly manage the modem, then system simplicity is maintained, but control over battery management is lost
Solution Approach 1:
The system provides self-service battery management through automated modem control. The CCS terminal automatically checks for remote service requests, activates the modem when needed, and shuts it down after the predetermined standby time expires without requiring customer intervention. This self-managing approach maintains system simplicity while providing effective battery management.

AI summary
A method for managing a remote service standby time of a connected car includes: notifying, by a connected car service (CCS) center which provides a remote service on a connected car, a customer terminal that a remote service standby mode needs to be ended; setting the remote service standby mode through a CCS application installed in the customer terminal; checking, by a CCS terminal installed in the connected car, whether a time to start the end of the remote service standby mode in accordance of the setting of the remote service standby mode has come; and, when the time to start the end of the remote service standby mode has come, requesting, by the CCS terminal, a shut-down of a modem installed in the connected car, and can efficiently manage the remote service standby time of the connected car.
