Abstract

PURPOSE: A method for remotely starting an automobile by using a mobile communication terminal is provided to conveniently start an automobile by directly inputting a remote start command even in a sleep mode, thereby reducing working time for remotely starting the automobile. CONSTITUTION: In a sleep mode, a control unit judges whether a user inputs a remote start key(S20). If so, the control unit executes wake-up(S22). The control unit controls a remote start unit for transmitting a wireless signal for remote start(S24). The control judges whether predetermined reference time passes(S26). If so, the control unit converts into the sleep mode again(S28).

Description

Vehicle remote start-up method using mobile communication terminal {vehicle remote start-up method by mobile tele-communication terminal}

The present invention relates to a method for remotely starting a vehicle using a mobile communication terminal, and more particularly, to a method for remotely starting a vehicle using a mobile communication terminal that enables remote starting even when a controller is in a sleep mode.

In recent years, as the society becomes more and more informational, mobile communication terminals are becoming an indispensable necessity for the information society, and the number of subscribers is exploding accordingly. In addition, the mobile communication terminal is now being developed as a complex information device with a variety of additional functions as well as simple telephone calls.

In view of the fact that a large part of the user of the mobile communication terminal owns a car, a technology for adding a remote start function to remotely start a car as an additional function is described in 1999. It is disclosed in the call.

1 is a block diagram of a remote starting device for a vehicle using a conventional mobile communication terminal. As shown in FIG. 1, a conventional mobile communication terminal includes a control unit 90, a wireless telephone unit 10 performing a unique function of the mobile communication terminal, and a remote starting unit 100 performing a remote start function. Is done.

In the above-described configuration, the controller 90 controls the overall operation of the mobile communication terminal. The memory 40 stores a predetermined program for controlling overall operations of the mobile communication terminal, and stores data input and output and various data processed according to the operation performed by the controller 90.

The duplexer 60 in the mobile communication function unit 10 communicates with the base station through the antenna AT and separates a signal transmitted and received. The receiver 70 receives the radio signal separated by the duplexer 60, amplifies, filters, and outputs the weak signal. The transmitter 50 filters, amplifies, and outputs a radio signal output from the audio unit 80 under a predetermined control to the duplexer 60. The audio unit 80 modulates the voice signal input through the microphone 84 into a wireless signal under the control of the controller 90, and demodulates the wireless signal received through the receiver 70 to voice the speaker 82. It sends out as a signal. In addition, the audio unit 80 detects the ring signal through the receiver 70 when the ring signal is generated from the base station and transmits the ring signal through the ringer. The display unit 30 includes a liquid crystal panel displaying various types of information, and is controlled by the controller 90 and receives and displays key data generated by the key input unit 20 and various information signals of the controller 90. The key input unit 20 includes a numeric key group and a function key group, and the remote start key is typically included in the function key group. In addition, the function key group of the key input unit 20 includes an end key for waking up the control unit 90 in the sleep mode.

Next, in the remote start function unit 100, the code generator 110 is connected to the main device (receiver) installed on the vehicle side of the remote start system when the remote start key is input from the key input unit 20 by the user. A command code for controlling the operation of each unit and an identification code (ID) for distinguishing a legitimate user are generated and applied to the encoder 120. The encoder 120 codes the command code applied from the code generator 110, that is, the command code and ID code for starting the engine, and transmits the code to the wireless transmitter 130, and the wireless transmitter 130 encodes from the encoder 120. The code data is converted into a wireless signal and transmitted to the main device.

2 is a flowchart illustrating a remote start method of a vehicle using a conventional mobile communication terminal. As shown in Fig. 2, in the conventional remote start method, in step S10, when the mobile communication terminal is in the sleep mode state, it is determined whether the end key is input from the user. As a result of the determination in step S10, if there is an input of the end key, the control unit 90 receives the input and performs a wake-up by itself in step S12. In step S14, the wireless telephone unit 10 is driven to an initial state. Only when the control unit 90 is a wake-up, the wireless telephone unit 10 can function.

When the user presses the remote start key in the state where the control unit 90 wakes up as described above, after checking this in step S16, the control unit 90 proceeds to step S18 to output a control signal to the remote start unit 100 so as to generate a remote start radio signal. Will be sent.

As described above, in the conventional remote starting method of a vehicle using a mobile communication terminal, there is an inconvenience and a time delay in which a remote starting command can be generated only when the remote starting key is pressed again while the control unit wakes up. Since the ignition key is disposed in a portion of the terminal body covered with the folder, it is inconvenient to operate the remote ignition key only by expanding the folder.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide a remote start method of a vehicle using a mobile communication terminal which allows a remote start command to be immediately input even in a sleep mode.

The present invention for achieving the above object is a wireless telephone unit for providing a wireless telephone communication function, a remote start unit for transmitting a remote start radio signal of the vehicle and operating in a sleep mode and a wake-up mode and the wake-up mode state A remote starting method of a vehicle using a mobile communication terminal configured to control operations of the wireless telephone unit and a remote starting unit only, the method comprising: determining whether an input of a remote starting key signal is present in a sleep mode; Performing a wake-up when there is an input of the remote start key signal, and then transmitting a remote start radio signal, and switching to the sleep mode after a predetermined time has elapsed. It is done.

In the above-described configuration, the remote start key is preferably provided on the side of the main body of the mobile communication terminal.

Hereinafter, with reference to the accompanying drawings will be described in detail a remote start method of a vehicle using a mobile communication terminal according to an embodiment of the present invention.

3 is a flowchart for explaining a method for remotely starting a vehicle using a mobile communication terminal of the present invention, and the controller 90 performs the main task. As shown in FIG. 3, in the remote start method of the present invention, the control unit 90 performs a step S20 to determine whether there is a remote start key input from the user. As a result of the determination in step S20, if there is a remote start key input, the process proceeds to step S22 to perform a wake-up by itself, and in step S24, the remote start unit 100 is controlled to transmit a remote start radio signal. . In this way, after the remote start radio signal is transmitted, step S26 is performed again to determine whether the predetermined reference time has elapsed. If the predetermined time has elapsed as a result of the determination in step S26, the control proceeds to step S28. 90 puts itself back to sleep mode. Steps S24 to S28 are given to reduce battery consumption.

On the other hand, in order to operate the radiotelephone unit 10, it is possible to press the end key as in the prior art, and even in this state, it is possible to press the remote start key to transmit a remote start radio signal.
