CONTROL DEVICE

A control device for controlling a vehicle that includes a headlight switchable between a first state and a second state in which the headlight is able to illuminate farther than in the first state, the control device including: a processing circuitry configured to execute automatic illumination switching control for setting the headlight to the first state or the second state and to execute an out-of-vehicle notification for switching the headlight between the first state and the second state at a predetermined cycle when another vehicle having a possibility to collide with the host vehicle is detected in front of the host vehicle. The processing circuitry executes the automatic illumination switching control in response to a request from a user of the host vehicle, and executes the out-of-vehicle notification in both cases where the automatic illumination switching control is set to be executed and not to be executed.
