In FIG. 2, reference numeral 10 denotes a car and 30 denotes a mobile communication terminal. The mobile communication terminal 30 receives an intermediate frequency signal having a predetermined frequency band from the vehicle, and displays a vehicle status message for the frequency band on the LCD.

3 is a block diagram of a vehicle condition checking system according to an exemplary embodiment of the present invention.

Hereinafter, with reference to FIG. 3, reference numeral 10 in the drawings is an automobile unit, and 30 is a mobile communication terminal. First, the configuration of the vehicle unit 10 will be described. The first sensor 11 is installed in four windows of the vehicle and senses the opening and closing state of the window when the vehicle is turned off and generates a first pulse signal. The second sensor 12 is a vehicle body sensor. When the shock is applied to the vehicle body, the second sensor 12 senses the shock and generates a second pulse signal. The battery 13 supplies power to the first half of the vehicle. The power supply detecting unit 14 detects whether power is supplied from the battery 13 when the vehicle is turned off and generates a third pulse signal. The light unit 15 receives power from the battery 13 to control lighting of headlights, taillights, brakes, and the like of the vehicle. The switch unit 18 is a normal close switch, and under the predetermined control, turns off the power supplied to the light unit 15. The first radio frequency unit 17 (hereinafter referred to as a first RF unit) 17 receives predetermined control and modulates and demodulates a radio signal transmitted and received through the antenna ANT1. The first controller 10 determines whether the starter 19 is on / off. In addition, when the starting unit 19 is turned off, the first control unit 10 monitors the first sensor 11, the second sensor 12, and the power detector 14, and the first sensor 11. And the second sensor 12 and the power detector 14 to check whether a pulse signal is input, and when the pulse signal is input, outputs predetermined data for each pulse signal, and outputs the first RF unit ( In 17), a radio signal is modulated and transmitted through an antenna. In addition, the control unit 18 receives a predetermined control command transmitted from the mobile communication terminal 30 through the antenna ANT1 and the first RF unit 17 and turns off the switch unit 18.

Referring to the configuration of the mobile communication terminal 30 in Figure 3, the second RF unit 32 demodulates the radio signal received through the antenna ANT2 and outputs the original signal. The second controller 37 analyzes the data from the demodulated signal. The alarm unit 36 generates an alarm under the control of the second control unit 37. The key input unit 34 includes a plurality of numeric keys and function keys, and outputs key data for the keys to the second control unit 37. The display unit 33 receives and displays display data on a key input from the key input unit 34 through the second control unit 37, and displays an operation state and a plurality of information of the mobile communication terminal. The memory 35 stores a predetermined operation program, temporarily stores data generated during the operation program, and stores option data for the operation program.

4 is a flowchart illustrating a vehicle state checking method in an automobile unit according to an exemplary embodiment of the present invention.

Hereinafter, referring to FIG. 4, the vehicle state checking method in the vehicle unit will be described in detail. First, the first controller 16 checks the starter 19 in step 501 to determine whether the start is turned off. When the start is turned off, the first controller 16 sets the vehicle unit 10 to the monitoring mode in step 503. When the monitoring mode is set in step 503, the first control unit 16 generates pulse signals from the first sensor 11, the second sensor 12, and the power detector 14 in steps 505, 506, and 507. Sequentially check whether a signal is input). When the first vehicle state signal is detected in step 505, the first controller 16 generates the first vehicle state signal in step 508, modulates the signal in the first RF unit 17, and then performs mobile communication through the antenna ANT1. It transmits a radio signal through a channel promised with the terminal. When the second sensor signal is detected in step 506, the first controller 16 generates a second vehicle state signal in step 509, modulates the signal in the first RF unit 17, and modulates the mobile communication terminal through the antenna ANT1. Transmit by radio signal on the channel promised with 30). When the power is detected in step 507, the first controller 16 generates a third vehicle state signal in step 510, modulates the first vehicle state signal in step 510, and then modulates the first vehicle state signal through the antenna ANT. Transmit by radio signal on the channel promised with 30).

When the sensor detection signal is transmitted in any one of steps 508 and 509, the controller 16 checks whether an emergency lock command is received from the mobile communication terminal 30. At this time, if the emergency lock command is received through the antenna ANT1 and the first RF unit 17, the first control unit 16 locks the door and the window.

In addition, after transmitting the third vehicle status signal in step 510, the controller proceeds to step 514 to determine whether a write unit off command is received from the mobile communication terminal 30 through the antenna ANT1 and the first RF unit 17. do. In this case, when the write unit off command is received, the first controller 16 turns off the switch 18 in step 515 to cut off the power supplied to the write unit 15.

5 is a flowchart illustrating a method of displaying a vehicle state in a mobile communication terminal according to an exemplary embodiment of the present invention.

Hereinafter, referring to FIG. 5, a method of displaying a vehicle state in a mobile communication terminal, the second controller 37 checks whether a wireless signal is received through a channel promised with the vehicle unit 10 in step 601. In this case, when the wireless signal is received through the antenna through the promised channel, the second controller 37 controls the alarm unit 36 to generate an alarm sound in step 603. After generating the alarm sound, the second control unit 37 determines in step 605, 606, and 607 what signal the received radio signal is. That is, it is determined whether it is the first vehicle state signal, the second vehicle state signal, or the third vehicle state signal. When the first vehicle state signal is detected in step 605, the second control unit 37 proceeds to step 608 and reads the first vehicle state message stored in the memory 35 to display on the display unit 34 (eg, Window open or WINDOW OPEN etc.). In contrast, when the second vehicle state signal is detected in step 606, the second controller 37 proceeds to step 609, and reads the second vehicle state message from the memory 35 and displays the second vehicle state message on the display unit 34 (eg, an impact). Detect or indicate IMPACT, etc.).

If the vehicle status message is displayed in one of steps 608 and 609, the second control unit 37 proceeds to step 611 and checks whether an emergency lock key is input from the key input unit 34. When the emergency lock key is input during the inspection, the second control unit 37 transmits the emergency lock command as a radio signal through a channel promised to the vehicle unit 10 through the antenna and the second RF unit 17.

In operation 607, when the third vehicle state signal is detected, the second controller 37 proceeds to step 610 to read the third vehicle state message from the memory 35 and displays the third vehicle state message on the display unit 34 (eg, write). ON or LIGHT ON light). After displaying the third vehicle status message, the second controller 37 proceeds to step 615 to check whether the write off key is input from the key input unit 34. When the write off key is input from the key input unit 34, the control unit 37 proceeds to step 617 to demodulate the write off command signal in the second RF unit 32 and then transmits it as a wireless signal through the antenna ANT2. .

As described above, the present invention has an advantage in that a situation in which a vehicle is more accurately determined by displaying the state of the vehicle by separately separating a case in which an impact is applied to the vehicle and a case in which the vehicle door is forcibly opened may be dealt with more accurately.

Another advantage of the present invention is that it is possible to prevent the discharge of the battery in advance by indicating whether the light is on.
