1. A method for recognizing a gesture made outside a vehicle comprising:
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, such that an attenuation of the ultrasound by the vehicle shell is less than or equal to a predetermined threshold;
emitting a plurality of ultrasounds having the frequency from an inner side of the vehicle shell, and 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;
determining a location of the hand and recognizing the gesture of the hand in response to determining that the obstacle is the hand; and
performing a command based on the location of the hand and the gesture of the hand to control the vehicle.
