## Abstract

A vehicle control system has a battery installed in a vehicle and capable of being charged with electricity supplied from an external power source outside the vehicle, an auxiliary device that operates by consuming the electricity supplied from the external power source or the battery, a communication unit that transmits information about the vehicle outward from the vehicle, and a control unit that directs the communication unit to transmit information about predetermined notice to a user of the vehicle when a predetermined condition for activating the auxiliary device is fulfilled and when the external power source is not available. The predetermined condition is that a request for activating the auxiliary device is made but the auxiliary device cannot start or continue operating.

## Claims

### Claim 1

A vehicle control system comprising:
a battery installed in a vehicle and configured to be charged with electricity supplied from an external power source outside the vehicle;
an auxiliary device configured to operate by consuming the electricity supplied from the external power source or the battery;
a communication device configured to transmit information about the vehicle outward from the vehicle; and
a control circuitry configured to direct the communication device to transmit information about a predetermined notice to a user of the vehicle when a predetermined condition for activating the auxiliary device is fulfilled and when the external power source is not available,
wherein the predetermined condition is that a request for activating the auxiliary device is made, remaining battery level of the battery is a predetermined value or higher, and the auxiliary device starts operating via the electricity from the battery, and
wherein, when the predetermined condition is fulfilled, the control circuitry directs the communication device to transmit information about a decrease in remaining battery level to notify that the remaining battery level decreases.

### Claim 2 (depends on 1)

The vehicle control system according to claim 1, wherein the control circuitry determines the predetermined condition after a lapse of a predetermined time from a point where a power of the vehicle is turned off.

### Claim 3 (depends on 1)

The vehicle control system according to claim 1, wherein the control circuitry does not provide the notice when the vehicle drives.
