Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

1 is a conceptual diagram schematically showing a vehicle control system according to an embodiment of the present invention.

In recent years, various functions have been added to the CCP (Communication Control Processor), and the key sensing function has been recently installed in the CCP. The key sensing function can know the position of a finger on a certain key by simply placing a finger on the key without inputting a specific key.

In recent years, the key operation method such as CCP is mounted on the vehicle rather than the touch input method. In the case of the touch input method, if the inside of the vehicle is wide, in order to perform the touch input, it is necessary to move the body forward to inconvenience the touch. However, in the case of the operation by the key, since the CCP and the like are mounted near the normal gear, there is a convenience that it can be operated without moving the body.

The present invention proposes a technique for preventing an undesired operation by showing a user how to perform an operation when a corresponding key is input by using the sensing function of the key through the CCP.

Hereinafter, a method of previewing the operation screen of the corresponding key using the sensing function of the key and a method of restoring the previous screen will be described.

The CCP 110 is a configuration in which a user senses a motion for sensing a key. This CCP 110 includes at least one key, e.g., an intensive key 111.

The head unit 120 performs a function of previewing the operation screen of the key based on the sensing determination result of the key obtained by the CCP 110. In addition, the head unit 120 may also perform a restore function to a previous screen.

An audio video navigation (AVN) system 130, a control system 140, and an ADAS (Advanced Driver Assistance Service) system 150 perform various vehicle functions under the control of the head unit 120. The control system 140 is a concept for controlling the in-vehicle apparatus and includes a MTS 141 and a TMU (Tele-Matics Unit) 142.

If the user presses a key and then performs an undesired operation, several keys must be used to return to the previous state. In order to reduce such inconvenience, in the present invention, the head unit 120 uses a sensing function of each key to show a screen in advance when the user inputs the key, and when the user inputs the key, So that the user can determine in advance whether or not to input the key.

Each key is divided into three states as follows.

- Push: Enter key

- Long: Enter key and hold for more than 0.8 seconds

- Release: Enter and release the key

In the present invention, two states are added in addition to these three states.

- Sensing On: A finger placed on the key

- Sensing Off: The finger disappears on the key

The process according to the state of the key is as follows.

The CCP 110 transmits the status information of the key to the head unit 120 according to each status. In the head unit 120, when the push / long / release state is transmitted, the head unit 120 performs an operation and changes to a screen suitable for the operation. However, when the Sensing On state is transmitted, the user must show the screen to be executed when the corresponding key is pressed. At this time, a screen to be executed is created and added to the screen stack (Stack). Then, if the user pushes the key, the push state is transmitted or the screen is not desired by the user, so that the finger is removed from the key to delete the screen previously added to the stack when the sensing off state is transmitted. Thereafter, when the push state is transmitted, the key function is performed.

Next, the method suggested in this document is explained. FIG. 2 is a reference diagram illustrating a process of transmitting messages between applications when a Sensing On state is transmitted according to an embodiment of the present invention. Referring to FIG.

When the sensing unit 120 receives the sensing key, the mode management unit 121 obtains the key, confirms which application the key processing unit 121 will process, and transmits the key to the corresponding application. At this time, each application receives the corresponding key, processes it in the application according to the state of the corresponding key, and displays the screen corresponding to the changed state after changing the state of the corresponding application.

However, the Push / Long / Release state is processed in the same manner as above, but when the Sensing On / Sensing Off state is transmitted, the Push / Long / Release state is not processed in the same manner. If the processing is performed in the above-described manner, the screen changes after the state of the application is changed. Therefore, the processing becomes very complicated to return to the previous state.

Accordingly, when the first application 122 receives the sensing-on state from the mode management unit 121, the first application 122 generates an application 1 '123 that performs the same function.

However, the application 1 '123 needs to know the state of the application 1 122 so that the state according to the key can be changed and a screen can be displayed. Thus, when the application 1 122 generates the application 1 '123, the application 1 122 stores its state in the shared memory 124. Then, the application 1 '123 can identify the state of the application 1 122 by checking the corresponding shared memory 124, process the corresponding key, and display the screen after changing the state.

When the application 1 '123 generates a screen, the corresponding screen is added to the screen stack 200, and the user can see the corresponding screen. FIG. 3 is a reference view showing a process of changing a screen stack according to an application creation according to an embodiment of the present invention.

On the other hand, when the existing application creates a new application that performs the same function as that of the existing application, that is, when the application 1 122 generates the application 1 '123 according to the above description with reference to FIGS. 2 and 3, In order to display the screen, it is only necessary to terminate the application 1 '123. FIG. 4 is a reference view showing an application termination process when a Sensing Off state is transmitted according to an embodiment of the present invention.

When the application 1 '123 ends, the previously created screen is also terminated. Therefore, the screen of the application 1' 123 disappears automatically on the screen stack 200, the screen of the application 1 122 is displayed, .

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention has been described with reference to Figs. Best Mode for Carrying Out the Invention Hereinafter, preferred forms of the present invention that can be inferred from the above embodiment will be described.

At least two operation keys may be provided in the vehicle. Such an operation key may be formed in the form of an intensive key within a predetermined distance from the driver's seat of the vehicle, or may be formed in the form of an intensive key on one side of the AVN system. In the above, the predetermined distance from the driver's seat means the distance that the driver can reach the arm while the driver is seated in the driver's seat.

The function execution control unit 520 performs a function of controlling the operation related to the operation key to be performed when the operation key state determination unit 510 determines that the operation key is pressed.

The preview execution control unit 530 performs a function of previewing a function related to the operation key when the operation key state determination unit 510 determines that the hand is located on the operation key .

The preview execution control unit 530 can control the preview to be executed while the hand is positioned on the operation keys.

The preview execution control unit 530 may generate a preview in the form of a screen and add it to the stack.

The preview execution control unit 530 generates a second application that performs the same function as the first application that performs a function related to the operation key, and can generate a preview using the second application.

The operation key condition determining unit 510 can further determine whether or not the hand is positioned on the operation key over the first reference time.

If it is determined that the hand is not located on the operation key for the first reference time or longer, the preview execution control unit 530 controls to preview the function related to the operation key. On the other hand, if it is determined that the hand is positioned over the first reference time on the operation key, the function execution control unit 520 controls the function related to the operation key to be performed.

In this embodiment, if it is determined that the hand is positioned over the first reference time on the operation key, the preview execution control unit 530 performs the control function, and the hand is not positioned over the first reference time on the operation key If so, the function execution control unit 520 may perform the control function.

On the other hand, the operation key condition determiner 510 can further determine whether the operation key is pressed for a second reference time or longer.

In this case, the function execution control unit 520 may control the other function associated with the operation key to be performed when it is determined that the operation key is pressed over the second reference time.

In this embodiment, various functions can be performed through one operation key. In this case, it is possible to distinguish the case where the operation key is pressed longer than the second reference time (Long) and the case where the operation key is pressed below the second reference time (Push) so that different functions can be performed .

However, in the present embodiment, it is also possible to set such that only a specific function can be performed regardless of whether the operation key is pressed / over the second reference time.

Meanwhile, the second reference time overpressure refers to a case in which the first pressurized state maintains the state for a second reference time or longer, and a case where pressurization continues over a second reference time.

On the other hand, the operation key condition determiner 510 may detect the number of contact points on the operation keys by the finger and the operation pattern of the finger.

In this case, the function execution control unit 520 may compare the operation patterns and the patterns stored in advance and control the functions related to the matched patterns to be performed. The preview execution control unit 530 may perform a preview operation Can be controlled to be executed.

Hereinafter, this will be described in more detail.

The operation key condition determiner 510 includes a touch pad that touches the user's finger and a touch sensor that detects a touch operation that is touched by the touch pad.

Preferably, the touch pad is disposed beside the gear transmission so that the right fingers can be touched naturally so that the visibility of the driver is not degraded.

The touch sensor may be configured to convert a change in pressure or capacitance applied to a specific portion of the touch pad into an electrical input signal. It is preferable that not only the position and area to be touched but also the pressure at the time of touch can be detected Do.

The preview execution control unit 530 receives control signals corresponding to the respective finger movement patterns sensed by the touch sensor from the operation key state determination unit 510 and then generates a pattern for various motions of the user's hands registered in advance in the memory And instructs the vehicle-mounted device to give an operation instruction corresponding to the control signals when they are compared with each other.

The display unit outputs the result on the screen in accordance with the command of the vehicle-mounted device.

Here, the finger operation pattern refers to a gesture of the finger indicating the number of fingers touching the touch pad, the movement direction, the movement width, the shape, and the like.

The vehicle-mounted device represents an AVN (Audio Video Navigation) system installed in the vehicle so that the driver or the passenger can enjoy various music and movies on the vehicle or utilize the navigation function while driving.

Next, an embodiment of an operation method using the above-described configurations will be described. Hereinafter, the operation of the on-vehicle device according to the finger operation pattern will be described.

When a user writes a specific character, such as J in English, on the touchpad with one finger (contact point 1), the vehicle-mounted device is activated. In this case, the area where the finger contacts the touch pad may be any area of the touch pad, but the center area of the touch pad is preferable considering the sensitivity of the touch sensor.

When the user double-clicks the touchpad with two fingers (touch point 2), the menu of the vehicle-mounted device is executed. In this case, whether or not the double-click is performed is judged whether or not the touch has been continuously touched twice within 0.5 seconds, for example. In this case, the area where the finger contacts the touch pad may be any area of the touch pad, but the center area of the touch pad is preferable considering the sensitivity of the touch sensor.

When the user rotates clockwise or counterclockwise while holding the touch pad with three fingers (contact point 3), the volume of the on-board device becomes large or small. In this case, the area where the finger contacts the touch pad may be any area of the touch pad, but the center area of the touch pad is preferable considering the sensitivity of the touch sensor.

When the user presses the left and right areas of the touch pad with two fingers (touch point 2), movement between the on-board devices is realized.

If the user rotates counterclockwise while pressing the touch pad with two fingers (touch point 2), it is executed as the previous step of the menu. In this case, the area where the finger contacts the touch pad may be any area of the touch pad, but the center area of the touch pad is preferable considering the sensitivity of the touch sensor.

When the user presses the touch pad with five fingers (touch point 5) in a blank state and then performs the operation, the operation to move to the basic menu after the current application type is implemented. In this case, the area where the finger contacts the touch pad may be any area of the touch pad, but the center area of the touch pad is preferable considering the sensitivity of the touch sensor.

Although the finger operation pattern is easy to memorize by the user, it is not limited to this, and it is natural that the finger operation pattern can be variously applied in consideration of the taste of the user.

Next, the operation method using the CCP will be described.

And a first step of detecting whether or not a finger is touched to the operation-key-condition determining unit 510 first. In this case, when a predetermined pressure or a predetermined capacitance is detected using the touch sensor, it is determined that the touch is detected.

And a second step of analyzing the number of spots of the activated finger when a touch is detected. In this case, the number of spots of the finger can be one to five, and is analyzed using a conventional multi-touch sensing method.

And a third step of executing a menu of the vehicle-mounted device according to the number of the spots and the gesture of the finger. In this case, each operation described above, that is, an operation according to the finger operation pattern is performed according to the execution form of the menu.

And a fourth step of outputting each result according to the menu execution on the display.

Next, an operation method of the vehicle function control device 500 will be described. 6 is a flowchart schematically showing a vehicle function control method according to a preferred embodiment of the present invention.
