## Abstract

A control device for controlling a host vehicle including: a processing circuitry configured to, when another vehicle traveling in a opposite direction to the host vehicle and having a possibility to collide with the host vehicle is detected in front of the host vehicle, execute an out-of-vehicle notification using a headlight based on a distance between the host vehicle and the another vehicle. When the distance is equal to or smaller than a first threshold and equal to or larger than a second threshold that is smaller than the first threshold, the processing circuitry executes the out-of-vehicle notification, and when the distance is smaller than the second threshold, the processing circuitry does not execute the out-of-vehicle notification or executes the out-of-vehicle notification with a notification intensity lower than that when the distance is equal to or smaller than the first threshold and equal to or larger than the second threshold.

## Claims

### Claim 1

A control device for controlling a vehicle that includes an external sensor configured to acquire surrounding information on a host vehicle and a headlight configured to illuminate ahead of the host vehicle, the control device comprising:
a processing circuitry configured to, when another vehicle traveling in an opposite direction to the host vehicle and having a possibility to collide with the host vehicle is detected in front of the host vehicle based on the surrounding information acquired by the external sensor, execute an out-of-vehicle notification using the headlight based on a distance between the host vehicle and the another vehicle, wherein
when the another vehicle is detected in front of the host vehicle and a travel speed of the host vehicle is equal to or larger than a predetermined value, the processing circuitry executes the out-of-vehicle notification based on the distance between the host vehicle and the another vehicle,
when the distance is equal to or smaller than a first threshold and equal to or larger than a second threshold that is smaller than the first threshold, the processing circuitry executes the out-of-vehicle notification, and
when the distance is smaller than the second threshold, the processing circuitry does not execute the out-of-vehicle notification or executes the out-of-vehicle notification with a notification intensity lower than that when the distance is equal to or smaller than the first threshold and equal to or larger than the second threshold.

### Claim 2 (depends on 1)

The control device according to claim 1, wherein
the headlight is switchable between a first state and a second state in which the headlight is able to illuminate farther than in the first state, and
the out-of-vehicle notification is headlight flashing in which the headlight is switched between the first state and the second state at a predetermined cycle.

### Claim 3 (depends on 1)

The control device according to claim 1, wherein
the another vehicle is a vehicle that travels in the opposite direction to the host vehicle and at least a part of which is on a travel lane of the host vehicle.

### Claim 4 (depends on 1)

The control device according to claim 1, wherein
when the another vehicle is detected in front of the host vehicle and a curvature of a road on which the host vehicle travels is equal to or larger than a predetermined value, the processing circuitry executes the out-of-vehicle notification based on the distance between the host vehicle and the another vehicle.

### Claim 5 (depends on 1)

The control device according to claim 1, wherein
when the another vehicle is detected in front of the host vehicle and a travel speed of the another vehicle is equal to or larger than a predetermined value, the processing circuitry executes the out-of-vehicle notification based on the distance between the host vehicle and the another vehicle.

### Claim 6 (depends on 1)

The control device according to claim 1, wherein
when a predetermined period has elapsed since the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification.

### Claim 7 (depends on 3)

The control device according to claim 3, wherein
when the another vehicle leaves the travel lane of the host vehicle after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification.

### Claim 8 (depends on 5)

The control device according to claim 5, wherein
when the travel speed of the another vehicle gets smaller than the predetermined value after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification.

### Claim 9 (depends on 1)

The control device according to claim 1, wherein
when a steering amount or a steering torque of the host vehicle gets equal to or larger than a predetermined value after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification.

### Claim 10 (depends on 1)

The control device according to claim 1, wherein
when a change amount of a yaw angle of the host vehicle from a start of the out-of-vehicle notification gets equal to or larger than a predetermined value after the out-of-vehicle notification is started, the processing circuitry ends the out-of-vehicle notification.
