Abstract
A vehicle includes: a Low Frequency (LF) communication unit transmitting an authentication request signal to a smart key through an LF communication network; a Radio Frequency (RF) communication unit receiving an authentication response signal from the smart key through an RF communication network; and a controller measuring an authentication response time period based on a time at which the authentication request signal is transmitted and a time at which the authentication response signal is received and determining whether authentication with the smart key is successful based on the authentication response time period.
