The vehicle includes a light-emitting part installed in the rear windshield wiper, a front camera that captures an image of the front of the own vehicle, a control unit that causes the light-emitting part to blink in conjunction with the operation of the rear windshield wiper to display the pattern, and a processing unit that acquires the pattern displayed by the blink of the light-emitting part of the preceding vehicle based on the image shot by the front camera.
