Abstract

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.

Claims (19)

1. An in-vehicle control device comprising a processor configured to:

control (i) a device of a first type, which is configured to switch an operation mode between a normal mode and a limit mode in which power consumption is limited compared to the normal mode and (ii) a device of a second type, which is not configured to switch the operation mode between the normal mode and the limit mode;

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 limit mode when the limited device is the device of the first type configured to switch the operation mode; and

stop power supply to the limited device when the limited device is the device of the second type not configured to switch the operation mode.

2. The in-vehicle control device according to claim 1 , wherein the information acquired from the outside is generated based on information including usage of a service while a vehicle is parked.

3. The in-vehicle control device according to claim 2 , wherein

the processor is configured to:

specify, when power consumption is being limited to at least one of the device of the first type and the device of the second type, a non-limited device that is a device of which limitation of power consumption is to be removed based on the information acquired from outside;

transmit to the non-limited device via the communication line an instruction to shift the operation mode to the normal mode, when the non-limited device is the device of the first type configured to switch the operation mode; and

supply power to the non-limited device, when the non-limited device is the device of the second type not configured to switch the operation mode.

4. The in-vehicle control device according to claim 1 , wherein

the processor is configured to:

specify, when power consumption is being limited to at least one of the device of the first type and the device of the second type, a non-limited device that is a device of which limitation of power consumption is to be removed based on the information acquired from the outside;

transmit to the non-limited device via the communication line an instruction to shift the operation mode to the normal mode, when the non-limited device is the device of the first type configured to switch the operation mode; and

supply power to the non-limited device, when the non-limited device is the device of the second type not configured to switch the operation mode.

5. The in-vehicle control device according to claim 1 , wherein

the device of the first type is connected to a power source without a relay controlled by the in-vehicle control device, and

the device of the second type is connected to the power source by a relay controlled by the in-vehicle control device.
