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.

Abstract: The precise placement device includes: a direction controller to which a placement unit having an insert and a drill is mounted, the direction controller controlling a direction of the placement unit; a precise transfer unit to which the direction controller is mounted, the precise transfer unit transferring the placement unit in the planar two-axis direction; a support table for fixing a target for insertion in which the insert is to be placed; and transfer units for transferring the precise transfer unit and the operating table.
