Patent ID: 8896417

Claim:
A system configured to operate a gate of a vehicle, comprising: a laser diode unit configured to show a plurality of step positions to operate the gate by radiating a plurality of laser points onto the ground beneath the vehicle; an ultrasonic wave sensor unit configured to measure a distance between a bottom of a rear bumper and the ground where the plurality of the step positions are shown, and sense a user's step based on a change in the distance due to the user stepping on the plurality of step positions; a gate driving unit configured to open or close the gate using a driving part; and a control unit configured to control the gate driving unit and open or close the gate according to the user succeeding in maintaining a step-on status during a predetermined time as sensed by the ultrasonic wave sensor unit; wherein the step-on status corresponds to the user stepping on the plurality of step positions in a predetermined order during the predetermined time, and wherein the laser diode unit removes each of the plurality of laser points on a step by step basis during the predetermined time in which the user is supposed to step on the plurality of step positions and maintain the step-on status.
