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 (21)

1. An in-vehicle control device comprising:

an electronic control unit (ECU) configured to:

acquire information from a plurality of vehicle controllers including a first type of device and a second type of device;

specify a limited device of which power consumption is to be limited, based on the acquired information;

determine a type of the limited device based on whether the limited device is configured to switch an operation mode between a normal mode and a limit mode, the limit mode being a mode in which the power consumption is limited compared to the normal mode without stopping power supply to the limited device;

in response to determining that the limited device is the first type of device having a function of switching the operation mode from the normal mode to the limit mode, transmit to the limited device via a communication line an instruction to switch the operation mode to the limit mode; and

in response to determining that the limited device is the second type of device that does not have the function, stop power supply to the limited device.

2. The in-vehicle control device according to claim 1 , wherein the acquired information is 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 ECU is configured to:

specify a non-limited device that is a device of which limitation of power consumption is to be removed based on the acquired information;

determine whether the non-limited device is the first type of device or the second type of device based on whether the non-limited device is configured to switch the operation mode;

in response to determining that the non-limited device is the first type of device, transmit to the non-limited device via the communication line an instruction to switch the operation mode to the normal mode; and

in response to determining that the non-limited device is the second type of device, supply power to the non-limited device.

4. The in-vehicle control device according to claim 1 , wherein the ECU is configured to:

specify a non-limited device that is a device of which limitation of power consumption is to be removed based on the acquired information;

determine whether the non-limited device is the first type of device or the second type of device based on whether the non-limited device is configured to switch the operation mode;

in response to determining that the non-limited device is the first type of device, transmit to the non-limited device via the communication line an instruction to switch the operation mode to the normal mode; and

in response to determining that the non-limited device is the second type of device, supply power to the non-limited device.

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

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

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