Telematics Master Controller Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles equipped with electronic devices and telematics communication systems experience battery depletion due to continuous power draw when turned off, leading to potential stranding of drivers.
Innovation Solution
A power consumption controller system that includes a telematics communications device, power consumption monitor, and power distribution switch, which transmits a notification message when the vehicle is turned off, allowing operators or service providers to selectively power down devices to extend battery life, with default settings for autonomous shutdown if no response is received.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic devices and telematics communication systems continuously monitor and report vehicle conditions, then the vehicle's safety and connectivity are improved, but the battery is depleted within two to four weeks when the vehicle is parked
Solution Approach 1:
The system dynamically adjusts the operational state of telematics devices based on vehicle status. When the vehicle is off, the telematics master controller selectively powers individual devices on or off based on priority levels and received directives, rather than maintaining a static on/off state for all devices
Solution Approach 2:
The system changes the power consumption parameters of telematics devices by receiving directives that specify power-down orders for individual devices. The master controller modifies the operational parameters (powered on/off state) of slave devices based on battery status and received commands, transforming the energy consumption characteristics of the system
2Ease of operation
If the telematics communication system continuously monitors vehicle conditions, then the ability to report vehicle status and respond to external commands is maintained, but the battery depletes leaving the driver stranded
Solution Approach 1:
The system implements feedback loops where the telematics master controller monitors battery status and device power states, receives directives from external sources or local devices, and adjusts device power states accordingly. This closed-loop control ensures the system responds to changing conditions while maintaining operational capability
Solution Approach 2:
The telematics master controller autonomously manages the power distribution to slave devices based on pre-assigned priorities and received directives, without requiring continuous external intervention. The system self-regulates which devices remain powered during vehicle-off periods based on importance and battery status

AI summary
When a vehicle is “off” many electrically powered devices will continue to draw power from the battery, which will eventually deplete the battery. Instead of leaving such devices on, when the engine is shut off, a message is transmitted from a vehicle's telematics communications device to one or more of: the operator, a telematics service provider or elsewhere, and which notifies the recipient of the power-down condition. The recipient of the message can thereafter respond with a directive that tells the telematics communications device which devices to leave powered on, turn off or schedule to be shut off. Absent such a message, the system powers down devices according to a default power down ordering.
