An in-vehicle control device includes a processor configured to: control a device of a first type, which has a function of switching an operation mode between a normal mode and a mode in which power consumption is limited compared to the normal mode in accordance with an instruction via communication and a device of a second type, which does not have the function; specify a limited device that is a device of which power consumption is to be limited, based on information acquired from outside; transmit to the limited device via a communication line an instruction to shift the operation mode to the mode in which power consumption is limited compared to the normal mode, when the limited device is the device of the first type; and stop power supply to the limited device when the limited device is the device of the second type.

In-vehicle control device

A network system includes a higher-level device, a first intermediate device connected to the higher-level device, and a second intermediate device connected to the higher-level device. The first intermediate device is configured to control supply of an electric power to a first lower-level device via a first device being able to be controlled to interrupt. The second intermediate device is configured to control supply of an electric power to a second lower-level device via a second device being able to be controlled to interrupt, the second lower-level device being a redundant component for the first lower-level device.

Network system providing redundant power supply configuration

A network system includes: an electric power system including a first power supply system and a second power supply system; a higher-level device connected to a first power supply of the first power supply system and a second power supply of the second power supply system; a first intermediate device connected to the first power supply of the first power supply system and configured to control supply of an electric power to a first lower-level device; and a second intermediate device connected to the second power supply of the second power supply system and configured to control supply of an electric power to a second lower-level device that is a redundant component for the first lower-level device.

Network system with two independent and redundant power supply systems

An on-board control apparatus has a power generation means that has a communication part; a storage battery that is chargeable by receiving electric power from the power generation means; a control means that is configured to be communicatable with the communication part and controls charging of the storage battery; and a state-of-charge measurement means that measures a state of charge of the storage battery. The control means transmits a signal that is to prohibit charging the storage battery to the communication part when an ignition of a vehicle is turned off, and the state-of-charge measurement means measures the state of charge of the storage battery, during a period of time in which charging the storage battery is prohibited, after the ignition of the vehicle is turned off.
