Abstract
A system for operating a gate of a vehicle may include a laser diode unit that shows step positions for operating the gate by radiating a plurality of laser points onto the ground, an ultrasonic wave sensor unit that measures the distance between the bottom of the rear bumper and the step positions and senses step input from a change in the distance due to the user stepping on the step positions, a gate driving unit that opens/closes the gate, using a driving part, and a control unit that controls the opening/closing operation of the gate driving unit on the basis of information on a step-on status kept for a predetermined time by the user which may be found by the ultrasonic wave sensor unit.
Claims17
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.
A method of operating a gate by using a system for operating the gate of a vehicle, comprising:
- a) detecting a position of a user who is in a predetermined area from the vehicle;
- b) showing a plurality of step positions by radiating a plurality of laser points onto the ground beneath the vehicle when the position of the user is detected;
- c) measuring a distance between a bottom of a rear bumper and the ground where the plurality of step positions are shown, and sensing a user's step based on a change in the distance due to the user stepping on the plurality of step positions;
- and
- d) controlling opening or closing operations of a gate driving unit, when the user succeeds in maintaining a step-on status for a predetermined time, wherein the step-on status corresponds to the user stepping on the plurality of step positions in a predetermined order during the predetermined time;
- wherein the user is informed that the step-on status is maintained by removing each of the plurality of laser points on a step by step basis during the predetermined time, between the step c) and step d).
A method of operating a gate by using a system for operating the gate of a vehicle, comprising:
- a) sensing a user's step when the user steps onto one of a plurality of step positions where one of a plurality of laser points are likely to be radiated onto the ground beneath the vehicle;
- b) showing the plurality of step positions by radiating the plurality of laser points onto the ground beneath the vehicle, upon sensing the user's step;
- c) measuring a distance between a bottom of a rear bumper and the ground beneath the vehicle where the plurality of the step positions are shown, and sensing the user's subsequent steps based on a change in the distance due to the user stepping on the plurality of step positions;
- and
- d) controlling opening or closing operations of a gate driving unit, when the user succeeds in maintaining a step-on status during a predetermined time, wherein the step-on status corresponds to the user stepping on the plurality of step positions in a predetermined order during the predetermined time;
- wherein the user is informed that the step-on status is maintained by removing each of the plurality of laser points based on a step by step basis during the predetermined time, between the step c) and step d).
