Step (S20) of determining whether the operation, the step of analyzing the sensor signal when the diagnostic switch is turned on (S30), determining whether a failure has occurred in the vehicle (S40), and a failure occurs If it is not the step (S50) to indicate that it is normal, if a failure occurs, the step of displaying the failure site and cause and repair method (S60), and determining whether the satellite communication switch is on (S70) and When the satellite communication switch is turned on, receiving a supercom rotor failure member and repair method through satellite communication (S80), displaying a nearby service center location and telephone number (S90), and call Determining whether the device is turned on (S100), requesting a tow truck when the call switch is turned on (S110), displaying the estimated time of arrival of the tow truck (S120), and terminating the operation (S130). Is made of.

The operation of the vehicle fault handling apparatus and method using the satellite communication according to the embodiment of the present invention by the above configuration is as follows.

When the power is applied, the operation procedure shown in FIG. 3, which is programmed and stored in the internal memory of the microcontroller 30, is executed by the microcontroller 30, so that the vehicle using the satellite communication according to the embodiment of the present invention. Operation of the fault handling apparatus is started (S10).

When the operation starts, the microcontroller 30 initializes all memory variables and then reads a signal input from the diagnostic switch DSW to determine whether the diagnostic switch DSW is turned on (S20). When the diagnostic switch DSW is turned on, the microcontroller 30 diagnoses the vehicle state by reading a signal input from the sensor unit 20 and analyzing the signal (S30). The sensor unit 20 is composed of sensors for detecting the operating state of each part of the vehicle.

As described above, after diagnosing the state of each part of the vehicle, the microcontroller 30 determines whether a failure has occurred in the vehicle (S40), and if the failure does not occur, outputs a signal to the display unit 40 so that the vehicle may stop. Shows the driver to the normal state (S50). However, when a slight failure occurs in any part of the vehicle, the microcontroller 30 uses the data stored in the internal memory to display the failure part, cause and repair method on the display unit 40 (S60). ). However, when a slightly complicated failure occurs, the microcontroller 30 displays this on the display unit 40 and asks the driver whether to perform satellite communication, and then the signal input from the satellite communication switch (SSW). It is determined whether the satellite communication switch (SSW) is on by reading (S70).

FIG. 1 is a diagram showing a situation in which the failure processing apparatus of the automobile 3 and the supercomputer of the traffic station 1 perform satellite communication via the GPS satellites 2. The above-described GPS satellite 2 is a satellite that is currently in a practical stage by developing the US Department of Defense for over 20 years for military purposes, and can use this to construct a positioning system. The GPS satellite 2 orbiting the earth transmits a radio wave of 1575.42 MHz in which the data necessary for position measurement is modulated by a frequency spread method. On the receiver side 3, a plurality of GPS satellites (in the case of two-dimensional positioning) Receiving radio waves from three satellites, four satellites in the case of three-dimensional positioning, the present position can be measured by calculating the time it takes for the radio waves to arrive by computer. Currently, the number of GPS satellites 2 is 16, and two-dimensional position measurement is possible for about 22 hours a day. However, upon completion of the GPS positioning system, a total of 24 satellites will be launched, including three more reserves, allowing three-dimensional positioning for 24 hours a day, anywhere in the world.

On the other hand, the micro-controller 30 receives the location and telephone number of the nearest service center from the supercomputer via satellite communication and displays it on the display unit 40 so that the driver can not contact the service center if he or she cannot possibly repair it. To do so (S90).

Next, the microcontroller 30 reads a signal input from the call switch CSW and determines whether the call switch CSW is turned on (S100). When the call switch (CSW) is turned on, the microcontroller 30 requests the tow truck by the traffic station 1 through satellite communication so that the tow truck can be driven by contacting the service centers nearby. S110). In addition, after receiving the estimated time of arrival of the tow vehicle from the traffic station 1 through satellite communication and displaying it on the display unit 40 (S120), the operation ends (S130).

As described above, in the embodiment of the present invention, after diagnosing a vehicle condition, a simple failure suggests a failure site and a repair method by itself, and a slightly complicated failure presents a failure site and a repair method through satellite communication with a traffic station. For example, a major deficiency may provide an apparatus and method for troubleshooting a vehicle using satellite communication, which has an effect of helping a driver request a tow vehicle through a satellite communication. This effect of the present invention can be modified and used by those skilled in the art in the field of vehicle diagnostic apparatus without departing from the gist of the present invention.
