[7] In order to resolve such problems, there are methods in the prior art for providing the function of a remote control device in a mobile terminal. These methods make it possible for the remote control device to control the vehicle control device through mobile communication in cases where the remote control device cannot control the vehicle control device through one-to-one communication. Moreover, like the above- mentioned method of using the remote control device the methods for providing the function of a remote control device in a mobile terminal make it possible to control the vehicle control device through one-to-one communication, too.

[43] Fig. 2 is a detailed diagram showing the vehicle remote control system for the automatic switching communication mode according to an embodiment of the present invention.
[44] As shown in Fig. 1, the vehicle remote control system for the automatic switching communication mode according to an embodiment of the present invention comprises a vehicle control device 10, a remote control device 20 and a mobile terminal 30.
[45] Herein, the vehicle control device 10 is deployed in the vehicle, checks the status of the vehicle, and controls the operation of the vehicle. The vehicle control device 10 has a function to operate every operation device in the vehicle after receiving the control signals from the remote control device 20 or the mobile terminal 30.
[46] Meanwhile, the remote control device 20 can transmit control signals to the vehicle control device 10 through one-to-one communication, and can transmit control signals to the mobile terminal through communication with the mobile terminal(in the following, this shall be referred as 'short-range wireless communication') after automatic communication mode switching to short-range wireless communication such as Bluetooth, Zigbee or WiFi.
[47] Meanwhile, the mobile terminal 30 has a function for short-range wireless communication with the remote control device 20. The mobile terminal 30 receives control signals from the remote control device 20 through short-range wireless communication, and then transmits the control signals to the vehicle control device 10 through mobile communication including GSM or CDMA, run by a nation or a mobile communication provider(in the following, this shall be referred as 'mobile communication').
[48] In above mentioned vehicle remote control system, the vehicle control device 10 can transmit response signals to the remote control device 20 or the mobile terminal 30 in response to the received control signals. The response signals can be status signals which informs the operation status of the vehicle. [49] Referring to Fig. 2 to describe the vehicle control device 10 and the remote control device 20 of Fig. 1 in detail, the vehicle control device 10 comprises one-to-one communication transceiver 13, mobile communication transceiver 15 and vehicle control unit 11 ; the remote control device 20 comprises one-to-one communication transceiver 21, short-range wireless communication transceiver 23, input unit 27, display unit 29, and remote control unit 25.

[51] Next, in the remote control device 20, one-to-one communication transceiver 21 communicates with the vehicle control device 10 through one-to-one communication; short-range wireless communication transceiver 23 communicates with the mobile terminal 30 through short-range wireless communication; input unit 27 is inputted commands by the user to transmit control signals to the vehicle control device 10 or to control the remote control device 20; display unit 29 displays the status of the response signals received from the vehicle control device 10 or a menu for controlling the remote control device 20 or the other menu.
[52] The remote control unit 25 is inputted commands from the input unit 27, transmits display-contents to the display unit 29, transmits or receives control signals through one-to-one communication transceiver 21 or short-range wireless communication transceiver 23.
[53] Moreover, the remote control unit 25 can switch communication mode automatically from one-to-one communication mode for communicating with the vehicle control device 10 through the one-to-one communication transceiver 21 to short-range wireless communication mode for communicating with the mobile terminal 30 through the short-range wireless communication transceiver 23 when one-to-one communication is unavailable.
[54]
Mode for the Invention
[55] Fig. 3 is a flowchart showing the vehicle remote control method for the automatic switching communication mode according to an embodiment of the present invention. Following steps are executed by the remote control device 20 if any specific executing device or unit is not referred. [56] As shown in Fig. 3, the vehicle remote control method for the automatic switching communication mode according to an embodiment of the present invention comprises steps from SlO to S28.
[57] In step S 10, if a command has been inputted to the input unit 27 by a user, the input unit 27 transmits control signals to the vehicle control device 10 through one-to-one communication after receiving control signals from input unit 27.
[58] In step S 12, the remote control device 20 waits for status signals in response to the control signals transmitted in step SlO.
[59] In step S 14, if the status signals are not received by the remote control device 20 in a certain period of time (the time period can be controlled), the remote control device 20 executes step S 16; if the status signals are received in time, the remote control device 20 executes the step S28.
[60] In step S 16 which proceeds when the status signals are not received by the remote control device 20 in step S 12, the communication mode of the remote control device 20 is switched automatically from one-to-one communication mode to short-range wireless communication mode such as Bluetooth, Zigbee or WiFi.
[61] In step S 18, the remote control device 20 searches the connectable mobile terminal
30. In the case where the connectable mobile terminal 30 is not searched, move to step S20.
[62] In step S20, the remote control device 20 commands the display unit 29 to display a waiting sign for the connectable mobile terminal 30 and then moves back to step S 18 to research connectable mobile terminal 30.
[63] In the case where the connectable mobile terminal 30 is searched in step S 18, it should be moved to step S22.
[64] In step S22, the remote control device 20 transmits control signals to the mobile terminal 30 through short-range wireless communication and the mobile terminal 30 transmits control signals to the vehicle control device 10 through mobile communication network, run by a country(or countries) or a mobile communication provider(or providers), such as GSM or CDMA.
[65] In step S24, the remote control device 20 waits for status signals in reply to the control signals transmitted in step S22.
[66] In step S26, in the case where the status signals are not received by the remote control device 20 in the previously settled waiting time, it should be moved back to step S22. In the case where the status signals are received by the remote control device 20 in the previously settled waiting time, it should be moved to step S28.
[67] In step S28, the remote control device 20 commands the display unit 29 to display the status after receiving status signals from the vehicle control device 10. After completion of step S28, the vehicle remote control method for the automatic switching communication mode of the present invention is completed.
[68] The vehicle remote control system and method for the automatic switching communication mode of the present invention is not limited to the above mentioned embodiments, and any variations and modifications may be made without departing from the scope of the present invention by the skilled in the art.
[69] In step SlO to S 14 of Fig. 3, for example, the method for checking the availability of one-to-one communication which is implemented in the way for transmitting control signals to the vehicle control device and receiving the status signals in response to the control signal through one-to-one communication can be implemented to check the availability of one-to-one communication periodically with an arbitrary time interval.
[70] Moreover, in step S 16 of Fig. 3, the step of automatic switching of the communication mode may be implemented to switch the communication mode in the case a user inputs instructions to switch the communication mode.
[71]
