Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for controlling communication between vehicles in a terminal apparatus,

The present invention relates to a method for controlling inter-vehicle communication of a terminal apparatus and an apparatus therefor, and more particularly, to a method and apparatus for inter-vehicle communication control of a terminal apparatus capable of solving the inconvenience of switching between connection modes of a vehicle and a terminal.

As the spread of automobiles increases, automobiles are becoming a necessity for modern people, and the demand for convenient car service related to vehicle management and maintenance is increasing.

On the other hand, as the technology of automobiles develops, the control of the important parts of the present automobiles is mostly performed by electronic control. Therefore, devices capable of acquiring information of various vehicles as well as electronic control from such devices and providing various services to the driver have been developed and commercialized and used.

In particular, a vehicle multimedia device supporting the hands-free call mode among the vehicle electric fields may include a vehicle multimedia device such as an AVN (Audio, Video, Navigation) head unit, and may support a hands-free call mode in the vehicle.

For example, by connecting a mobile phone having a Bluetooth function owned by a driver with a vehicle multimedia device, a hands-free call mode is supported. To this end, the vehicle multimedia device includes a local communication unit such as a Bluetooth module and a control unit for controlling the communication unit. This device configuration allows the operator to make hands-free calls in hands-free mode.

The Bluetooth RF specification applied to the audio / AVN system and the Bluetooth RF specification applied to the mobile phone are RF Class 2 and RF communication with each other. The Power Class 2 RF specification requires a transmitter of -6 to +4 dBm and a receiver of -70 dBm or less. It is assumed that communication is possible within about 10m as an approximate communication distance.

Generally, Bluetooth used in current vehicles can not control the communication distance and TX output with the partner, and the handset maker is setting up the maximum Bluetooth communication distance in the manufacturing process.

However, when the driver carries out a paired mobile phone to the outside of the vehicle while the vehicle is turned on, it is impossible to make a call to the main body of the mobile phone due to the hands-free connection of the vehicle even at a distance of 5 to 30 meters A situation arises.

As described above, since the connection and disconnection points of the hands-free calls differ from the time of getting on and off the vehicle, inconveniences arise in use.

Accordingly, there is a need for a technique that automatically switches to a hands-free mode. However, a switching delay is required only when the switching is determined depending on the strength of a radio wave or a pairing. As a result, .

In this way, the hands-free function using the vehicle's own speaker is not able to communicate due to a certain period of time being maintained even when the driver gets off the car. In addition, even when the user is riding in a busy state, the hands- Problems are also occurring.

As described above, in addition to the spread of smart phones, most of the vehicles support Bluetooth handsfree, and only the hands-free kit is sold separately. However, since such a problem is not considered, the inconvenience is increasing, Is expected to be.

Currently, various services using communication between smartphone and vehicle have been developed and installed in vehicles, but improvement is required due to a lack of accuracy in terms of user convenience, awareness, and operation.

In order to solve the above-described problems, the present invention provides a terminal device capable of improving user convenience by determining whether to switch between a hands-free and a general call mode through wireless connection control according to a result of status check of the terminal device, The purpose is to provide.

It is another object of the present invention to provide a terminal device and an operation method thereof that can bring about differentiation through accuracy and delay reduction in comparison with existing communication mode switching technology.

According to an aspect of the present invention, there is provided a terminal device for supporting inter-vehicle wireless communication, the terminal device comprising: a wireless communication unit for performing wireless connection with the vehicle system; A sensor unit for checking a state of the terminal device previously set while the wireless connection is maintained; And a controller for controlling the maintenance or release of the wireless connection according to the state of the terminal device.

According to another aspect of the present invention, there is provided a method of operating a terminal device supporting wireless communication between vehicles, the method comprising: performing a wireless connection with the vehicle system; Checking a state of the terminal device set in advance while the wireless connection is maintained; And controlling the maintenance or release of the wireless connection according to the state of the terminal apparatus.

According to the embodiment of the present invention, it is possible to determine whether or not the driver is on the driver's seat based on the result of status check of the terminal device, and thereby determine whether to switch between the hands-

In addition, since the combined determination using the communication signal strength not only reduces battery consumption but also reduces accuracy and delay, it can differentiate it from existing switching technology.

Further, the present invention can be applied to a technology for integrating communication control with a smartphone through cooperation with a vehicle manufacturer.

The sensing unit 140 senses the current state of the terminal device 100 such as the open / closed state of the terminal device 100, the position of the terminal device 100, the presence or absence of user contact, the orientation of the terminal device, And generates a sensing signal for controlling the operation of the terminal device 100. For example, when the terminal device 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. It is also possible to sense whether the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141.

The output unit 150 is for generating output related to the visual, auditory or tactile sense and includes a display unit 151, an audio output module 152, an alarm unit 153, and a haptic module 154 .

The display unit 151 displays (outputs) information to be processed by the terminal device 100.

When the terminal device 100 is in the video communication mode or the photographing mode, it displays the photographed and / or received video or UI and GUI.

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, and a 3D display.

The intensity and pattern of the vibration generated by the hit module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The interface unit 170 serves as a path for communication with all the external devices connected to the terminal device 100. The interface unit 170 receives data from an external device or receives power from the external device and transfers the data to the respective components in the terminal device 100 or allows data in the terminal device 100 to be transmitted to external devices.

In addition, for example, the controller 180 may determine whether or not the driver is getting off based on the state of the sensed terminal device 100, and may control the maintenance or release of the wireless connection according to whether or not the driver gets off.

For example, the control unit 180 may determine the strength of a communication signal of the wireless connection, and may control the sensor unit 140 to check the state of the terminal apparatus only when the communication signal strength is less than a predetermined value.

3 is a flowchart illustrating an operation method of a vehicle communication control apparatus according to an embodiment of the present invention.

Referring to FIG. 3, the terminal device 100 senses the vehicle system 200 (S100).

The terminal device 100 can detect the wirelessly connectable vehicle system 200 located nearby via the wireless communication unit 120. [

Then, the terminal device 100 determines a wireless connection mode for wireless connection with the sensed vehicle system 200 (S110).

The wireless connection method may be any one of the short-range or wireless Internet connection methods as described above. The control unit 180 of the terminal device 100 can determine an appropriate communication method through the pre-connection communication with the detected vehicle system 200.

Then, the terminal device 100 performs a wireless connection with the sensed vehicle system 200 (S120).

For example, in the case of a Bluetooth connection, the terminal device 100 can be interconnected with the vehicle system 200 using preset or automatically set pairing data. When connected via Bluetooth, the call signal and the voice signal can be transmitted and received using RF communication.

After wireless connection, the terminal device 100 determines whether a call signal is received through the mobile communication network to the wireless communication unit 110 (S130).

The control unit 180 of the terminal device 100 controls the output unit 150 to display the telephone reception or transmit a voice signal to the vehicle system 200 at step S140. Then, it is possible to control the voice call to be performed through the speaker and the microphone of the vehicle system according to the user selection input.

Meanwhile, the sensor unit 140 of the terminal device 100 senses the state of the terminal device 100 (S150).

The sensor unit 140 may sense the state of the terminal device 100 during the wireless connection. The sensed data may be output as status information, and the control unit 180 may determine whether or not the driver is getting off based on the status information.

The state information of the terminal apparatus 100 sensed and output from the sensor unit 140 may include motion information of the terminal apparatus 100, for example.

The sensor unit 130 may sense the state of the terminal device 100 only while the wireless connection is maintained and the call connection is maintained under the control of the controller 180. [

Generally, since the problem that the present invention tries to solve during a call in which a user maintains a call connection is generated, it is possible to increase the battery efficiency by blocking the sensing power at a time when the importance of the wireless connection maintenance judgment is low.

The controller 180 determines whether or not the driver is off according to the state of the terminal device 100 sensed by the sensor unit 130 (S160).

According to the embodiment of the present invention, the control unit 180 can determine whether or not the driver in the call is getting off according to the state of the terminal device 100. [

For example, if the vertical motion of the terminal device 100 is determined to be equal to or higher than the threshold value according to at least one of the acceleration sensor, the geomagnetic sensor, and the gyro sensor among the terminal status information, the controller 180 may terminate the Bluetooth connection.

The acceleration sensor is a sensor capable of measuring the direction of acceleration and acceleration when a motion occurs. Specifically, the acceleration sensor outputs a sensing value corresponding to a gravitational acceleration that varies depending on the inclination of the apparatus to which the sensor is attached. Accordingly, when the acceleration sensors are disposed on both side edge regions of the terminal device 100, the output value sensed by each acceleration sensor can be changed when the terminal device 100 is moved. The controller 180 calculates a pitch angle and a role angle using an output value sensed by each acceleration sensor. Accordingly, it is possible to determine the direction of movement of the terminal device 100 based on the degree of change of the pitch angle and the roll angle sensed by the respective acceleration sensors.

As described above, the sensor unit 140 may detect movement of the terminal device 100 using a gyro sensor or a geomagnetic sensor in addition to the acceleration sensor. The gyro sensor is a sensor that detects angular velocity by measuring the force of Coriolis acting in the speed direction when rotational motion occurs. According to the measurement value of the gyro sensor, it is possible to detect in which direction the rotation is performed, so that the rotation direction can be detected.

The geomagnetic sensor is a sensor that detects the azimuth using a two-axis or three-axis fluxgate. When the geomagnetic sensor is implemented as a geomagnetic sensor, the geomagnetic sensor disposed at each edge of the terminal device 100 moves its position when its edge portion moves, and outputs an electric signal corresponding to the geomagnetism change due to the movement.

The control unit 180 may calculate the yaw angle using the value output from the geomagnetic sensor. Accordingly, it is possible to determine various motion characteristics such as a moving direction and a moving speed according to the calculated change in yaw angle.

The configuration and sensing method of the above-described sensors may be applied to the terminal device 100 individually or in combination with each other.

Typically, since the user of the terminal device 100 positions the portable terminal stationary at a specific position in the vehicle during operation, the vertical movement may be less likely to occur beyond the threshold value except for the movement of the vehicle in the horizontal direction. Accordingly, when it is determined that the vertical motion of the terminal is equal to or higher than the threshold value, the controller 180 can change the hands-free mode of the portable terminal to the normal call mode by terminating the Bluetooth connection.

In addition, the control unit 180 may determine whether or not the driver is off by wireless communication with the vehicle system 200. For example, when the driver's departure from the vehicle system 200 is detected by the vehicle system 200 or the intensity of the wireless communication decreases, the controller 180 may detect the motion information or the driver departure information detected by the vehicle system 200 It is possible to determine that the driver is getting off.

On the other hand, when the driver does not get off or the call signal is not received, the control unit 180 can maintain the wireless connection (S165).

If the driver gets off the control unit 180, the control unit 180 terminates the wireless connection (S170).

As described above, when the controller 180 of the terminal device 100 determines that the driver is getting off according to the vehicle status information, the controller 180 may terminate the Bluetooth connection.

4 is a flowchart illustrating an operation method of a vehicle communication control apparatus according to another embodiment of the present invention.

Meanwhile, the control unit 180 may determine the distance between the terminal device 100 and the vehicle system 200 according to the communication signal strength with the vehicle system 200.

In this case, there is a problem that it is difficult to accurately determine whether the vehicle is inside or outside because the distance between the vehicle system and the vehicle system is determined only by the intensity of the communication signal. For example, when the communication signal strength is equal to or greater than a predetermined value, the controller 180 may determine that the terminal device 100 is located inside the terminal device 100, but may determine whether the user holds the terminal device 100 and is getting off the vehicle I can not.

Therefore, according to the embodiment of the present invention, the accuracy of the hands-free switching operation according to the wireless connection mode control can be improved by simultaneously considering the status information and the communication signal strength of the terminal device 100 described above.

For this, the controller 180 can determine whether or not the driver is getting on and off based on the state information of the terminal device 100, and can also determine the distance between the terminal device and the vehicle based on the communication signal strength described above. Here, in order to reduce the power consumption and simplify the operation, the communication signal strength can be determined first.

According to the strength of the communication signal, the controller 180 can increase the distance between the terminal device and the vehicle system and end the hands-free mode when it is determined that the driver is getting off. Accordingly, not only the reliability of the hands-free switching operation can be improved, but also user convenience can be improved. The flowchart of FIG. 4 illustrates the operation of the control unit 180 as described above.

The control unit 180 first determines the strength of the communication signal (S200), and determines whether the signal strength is decreased (S210).

If the signal intensity is decreasing, the controller 180 controls the sensor unit 140 to sense the acceleration of the terminal device 100 (S220).

The control unit 180 controls the sensor unit 140 to sense the geomagnetism or the gyro sensor at a predetermined acceleration or higher (S230).

Thereafter, the control unit 180 determines whether or not the driver is getting on or off according to the sensing result (S240).

If the control unit 180 determines that it is getting off the boarding determination result, the control unit 180 terminates the wireless connection (S250).

Meanwhile, if the control unit 180 determines that the vehicle has been boarded or not yet ascended or the radio signal intensity has not decreased, the control unit 180 maintains and controls the wireless connection (S255).

Also, the controller 180 can retry the wireless connection even after the wireless connection is terminated, if the driver is determined to ride again or the strength of the wireless connection signal is increased. Accordingly, when the user rides again during a call, the hands-free connection that was disconnected is automatically reconnected, thereby further enhancing user convenience.

5 is a diagram for explaining a screen output by the terminal device 100 according to an embodiment of the present invention.

5, the terminal device 100 may include a display unit, and may output the control result of the control unit 180 of the terminal device 100 to the message 101 through display. Further, the message 101 may be output as a voice.

Accordingly, the user can know from the message 101 the result of the control unit 180 determining whether to get off the driver and the result of maintenance / control of the wireless connection.

The method according to the present invention may be implemented as a program for execution on a computer and stored in a computer-readable recording medium. Examples of the computer-readable recording medium include a ROM, a RAM, a CD- , A floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional programs, codes and code segments for implementing the above method can be easily inferred by programmers of the technical field to which the present invention belongs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
