Power supply management system for vehicle mounted apparatus

摘要

A power supply management system and method for an on-board device that, when required by a user of the on-board device and/or when a power supply is capable of supplying electric power, allows remote operation of the on-board device by supplying electric power to a communication device so as to place it in a communication-capable state. Further, when not required by the user of the on-board device and/or when the power supply is not capable of supplying electric power, it is possible to inhibit discharge of a power supply by interrupting supply of electric power to the communication device.
