A method for recognizing a gesture made outside a vehicle includes setting a frequency of an ultrasound based on a thickness of a vehicle shell of the vehicle and an attenuation coefficient of the vehicle shell, emitting a plurality of ultrasounds having the frequency outwardly from an inner side of the vehicle shell, receiving a plurality of reflected waves returned by an obstacle reflecting the plurality of ultrasounds, determining whether the obstacle is a hand according to time differences between emission times of the plurality of ultrasounds and reception times of the plurality of reflected waves corresponding to the plurality of ultrasounds, and recognizing the gesture of the hand in response to determining that the obstacle is the hand.
