Abstract

PURPOSE: An AVN(Audio, Visual And Navigation) system and a control method thereof are provided to ensure safe driving since an AVN system is controlled through hand motions without direct contact, so eye movement decreases. CONSTITUTION: An AVN system(10) comprises a plurality of sensors(110_1~110_n) and a control unit(120). The sensors sense a user's hand and transmit a corresponding signal. The control unit receives the signal from at least one of the sensors, checks the motion of the sensed hand and performs a corresponding function to the motion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram showing an AVN system according to an embodiment of the present invention.

As shown in FIG. 1, the AVN system 10 according to an exemplary embodiment of the present invention includes a plurality of sensors 110_1 to 110_n and a controller 120.

The plurality of sensors 110_1 to 110_n detect a user's hand near the AVN system 10 and transmit a signal corresponding thereto. Here, the plurality of sensors 110_1 to 110_n may be configured with four sensors disposed at each corner of the AVN system 10.

When the controller 120 receives a signal from at least one of the plurality of sensors 110_1 to 110_n, the controller 120 detects the movement of the user's hand and executes a function corresponding to the movement of the hand.

In detail, when the control unit 120 receives a signal from at least one of the plurality of sensors 110_1 to 110_n, the control unit 120 determines the order in which the signals are transmitted by the sensors transmitting the signals and the plurality of sensors 110_1 to 110_n. Check the movement of the user's hand (ie, direction of movement, gesture, etc.). The function corresponding to the movement of the hand is searched for and executed.

In this case, the control unit 120 may detect the movement of the hand only when the separation distance between the sensor detecting the user's hand and the user's hand, which is identified from the signal, is greater than or equal to a predetermined distance, thereby preventing misunderstanding and malfunction of the AVN system 10. Can be.

The controller 120 may check the order in which the signals are transmitted and the movement of the user's hand from the sensors transmitting the signals and the plurality of sensors 110_1 to 110_n using an application program or a software algorithm.

Meanwhile, the AVN system 10 registers the movement of the hand corresponding to each function in advance and stores the data about the movement in a storage unit (not shown).

Accordingly, the controller 120 may execute a function corresponding to the movement of the hand using the stored data. In addition, the controller 120 may ignore the movement of an unregistered hand or may guide the movement (manipulation) of an unregistered hand.

Meanwhile, the AVN system 10 may additionally register and use a movement of a hand for executing a function according to a user's request.

Hereinafter, a driving method of a controller according to an exemplary embodiment of the present invention will be described with reference to FIGS. 2 and 3. 2 and 3 are exemplary views illustrating a driving method of a control unit according to an exemplary embodiment of the present invention. 2 and 3 illustrate an AVN system 10 having four first to fourth sensors respectively provided at four corners.

Referring to FIG. 2, when a user's hand moves from left to right, first or third sensor 1 or 3 first detects the user's hand and transmits a first signal corresponding thereto. The fourth sensor 2 or 4 detects the user's hand and transmits a second signal corresponding thereto to the controller 120, respectively.

The controller 120 determines that the user's hand moves from the left side to the right side of the AVN system 10 using the first signal and the second signal, and searches for and executes a function corresponding thereto.

At this time, the control unit 120 may determine that the movement from the left to the right to instruct the conversion from the radio mode to the DMB mode.

As shown in FIG. 3, when the user's hand moves from the left side to the upper right corner through the upper left corner, the first sensor 3 first, the second sensor 1 second, and the second second Each sensor 2 detects a user's hand and transmits a first signal, a second signal, and a third signal corresponding thereto to the controller 120, respectively.

The controller 120 checks the order in which the first to fourth sensors 1 to 4 detect the user's hand from the transmitted first, second and third signals, thereby moving the hand in a '┏' shape. Identify and execute the function corresponding to the movement of the type.

In this case, the controller 120 may determine that the movement of the '┏' type indicates an entry into the navigation mode.

Hereinafter, an AVN system control method according to an exemplary embodiment of the present invention will be described with reference to FIG. 4. 4 is a flowchart illustrating a method of controlling an AVN system according to an exemplary embodiment of the present invention.

Referring to FIG. 4, when a plurality of sensors 110_1 to 110_n detect a user's hand in proximity (S410), the plurality of sensors 110_1 to 110_n transmit a signal corresponding thereto (S420).

Subsequently, the controller 120 receives signals transmitted from the plurality of sensors 110_1 to 110_n and uses the same to grasp the movement of the user's hand (S430).

In detail, when the control unit 120 receives the signals transmitted by the plurality of sensors 110_1 to 110_n, the control unit 120 checks the sensors transmitting the corresponding signals, and when receiving the plurality of signals, the sensors 110_1 to 110_n. ) Together with the order in which you detected the user's hand to determine the hand movements.

At this time, the controller 120 checks whether the separation distance between the plurality of sensors 110_1 to 110_n and the user's hand is less than or equal to a predetermined distance, and determines the movement of the user's hand only when the separation distance is less than or equal to the predetermined distance.

Next, the controller 120 searches for and executes a function corresponding to the movement of the hand (S440).

Thus, the present invention can operate the AVN system through the movement of the hand without direct touch, it is possible to reduce the gaze movement for the operation, there is an effect that can lead to safe driving.

In the present specification, the AVN system has been described as a reference, but the configuration of the present invention can be applied to an audio system, a navigation system, and the like.

While the present invention has been described in detail with reference to the accompanying drawings, it is to be understood that the invention is not limited to the above-described embodiments.
