BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic parking apparatus for a vehicle, and more particularly, to an automatic parking apparatus for a vehicle.

In general, novice drivers and female drivers often have difficulty parking. In particular, since it is a matter of fact that the parking space is narrow in spite of the high penetration rate of the automobile, parking the vehicle at a desired position backwards is a pitiful problem for the driver who does not operate the vehicle.

Recently, in consideration of such circumstances, for the sake of convenience of the driver, there is a study on an automatic parking system in which a parking space is identified through a sensor mounted on a vehicle, and a control unit automatically controls the vehicle to automatically park the vehicle in the parking space. .

As an example, the SPAS (Smart Parking Assist System) is a function that automatically controls the steering wheel for parking while the driver is on board. However, even in the case of using the technology, other vehicles must be parked in front of and behind the vehicle (at the time of parallel parking) or at the left and right (at the time of the vertical parking). That is, there is a problem that it is difficult to perform automatic parking if there is no other vehicle or obstacle for recognizing the parking space through the sensor. Further, when the surrounding environment is recognized using ultrasonic waves, the corner of the obstacle can not be correctly recognized due to the physical limitation of ultrasonic measurement.

In order to solve the problems of the prior art of the present invention, there is provided a self parking apparatus capable of performing a parking operation by utilizing various sensors mounted on a vehicle.

The automatic parking apparatus for a vehicle according to an embodiment of the present invention includes an operation recognition unit for recognizing a user gesture, a voice recognition unit for recognizing a user voice, a touch recognition unit for recognizing a user's touch, A recognition information collecting unit that receives information from at least one of the recognition unit and the touch recognition unit and generates recognition information, and a recognition unit that analyzes the generated recognition information and controls the operation of the vehicle based on the interpreted recognition information And a control unit.

INDUSTRIAL APPLICABILITY The automatic parking apparatus for a vehicle according to the present invention can use various sensors provided in a vehicle at the time of performing a parking operation of the vehicle, so that it is possible to perform convenient parking.

In addition to the effect of improving the user's convenience, there is also an effect of reducing the damage to other vehicles and reducing the time required for parking the vehicle, thereby saving fuel and reducing environmental pollution.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
