FIG. 1A is a block diagram of a self diagnosis information transmission system of a vehicle mounted on a vehicle and transmitting information indicating whether the vehicle has a failure / accident. FIG. 1B is a diagram illustrating a service of receiving an information transmitted from a failure / accident vehicle to provide an accident handling service. Is a block diagram of an incident handling service providing system.

In FIG. 1A, the ECU denoted by reference numeral 110 is a vehicle's driving information, RPM (engine rotational speed), vehicle speed, and information for determining whether the vehicle has a failure, for example, coolant temperature value and angle of the throttle valve. Information such as a value and an oxygen sensor value is detected and provided to the scanner 115. The method of detecting the above-mentioned information in the ECU is easily understood by those skilled in the art, and thus, detailed descriptions thereof are omitted herein.

The scanner 115 connected to the ECU 110 codes each of the values detected and provided by the ECU 110, provides the encoded values to the first data converter 140, and displays them for the driver's view.

In addition, the plurality of sensors 120 are installed at the outside of the vehicle, for example, installed at the side of the vehicle, the front of the vehicle, and the rear of the vehicle, and each of the sensors is a shock sensor when a collision occurs in the vehicle. The generated vehicle shock and the amount of shock are sensed and provided to the first data converter 140.

Meanwhile, in order to implement the present invention, a location information providing unit (GPS: Global Positioning System) 125 should be built in the vehicle, and the GPS providing unit 125 may provide location information provided from a satellite, that is, an example of current location information of the vehicle. For example, the latitude and longitude values are always received and provided to the first data converter 140. In addition, in the vehicle of the present invention, a predetermined ID (Indentifier) should be given to the vehicle, and in the present specification, the vehicle ID providing unit 130 provides ID information of the vehicle. 1 can be easily stored by those skilled in the art of the present invention.

The first data converter 140 encodes the self-diagnosis information, that is, the values detected by the ECU, the sensor values according to the impact of the vehicle, the current position information of the vehicle, and the vehicle ID, as described above. To provide.

The second data converter 145 receives the code values provided from the first data converter 140 and transmits the codes to the wireless communication network, for example, a code division multiple access (CDMA) network or a time division multiple access (TDMA) network. The second data converter 145 converts the code from the first data converter 140 according to a protocol used in the wireless communication network. The second data converter 145 converts the code from the first data converter 140 according to a protocol used in the wireless communication network. In order to prevent an error that may occur, a predetermined error correction code may be added to a code of the first data converter 140 and an encryption code may be added to prevent eavesdropping by another person.

The first information transmitter / receiver 150 stores the code values for the self-diagnosis information of the vehicle, the current location information of the vehicle, and the vehicle ID information provided by the second data converter 145 through the wireless communication network. It transmits to the processing service providing system, receives the information transmitted from the incident processing service providing system, that is, text information and voice information to inform the user, and transmits the user selection information to the incident processing service providing system.

That is, as described below, the accident processing service providing system of FIG. 1B receives information from a vehicle equipped with the self-diagnostic information transmitting system of FIG. 1A, detects whether the vehicle is in an accident / failure, and detects the accident / failure of the vehicle. In the event of occurrence, a predetermined message (text and voice message) is provided to the wireless communication network inquiring whether the driver of the vehicle wants to receive an accident handling service. The first information transceiving unit 150 configured in the self-diagnostic information transmitting system of FIG. 1A is a text information display unit 160 of text information of an accident processing service providing system provided through a wireless communication network, and voice information of a voice generator. 165), the driver of the vehicle is notified, by text and voice, of a message asking whether to receive service through the accident handling service system.

The driver of the vehicle may select whether or not to receive the message of the text information display unit 160 and the voice generator 165, that is, the service of the accident handling service system, or not to receive the service, and the selection may be performed by the user selector 155. This can be done using. That is, the user selector 155 is configured with keys indicating whether the service is received or not received, and the first information transceiver 150 transmits a signal (hereinafter, referred to as a user selection signal) indicating a key operated by the user. The first information transceiving unit 150 transmits a user selection signal of the user selection unit 155 to the accident processing service system. The incident handling service system determines whether to provide an incident handling service according to a user selection signal from the first information transmitting and receiving unit 150.

On the other hand, a large vehicle accident may occur and both the driver and the occupant may lose consciousness. In this case, the driver cannot select whether or not to receive the accident handling service of the accident handling service system and inform the accident handling service providing system. As will be described later, if a user selection signal indicating whether to receive a service from an accident vehicle within a predetermined time is not provided, an accident handling service for the accident vehicle must be performed.

In the self-diagnostic information transmission system of the present invention, a radio frequency (RF) signal generation unit 170 is provided, and the first information transmission / reception unit 150 is a text information display unit 160 according to information from an accident processing service providing system. And if the key of the user selector 155 is not input within a preset time after driving the voice generator 165, the RF signal generator 170 is operated. That is, if a large vehicle accident occurs and both the driver and the passenger lose their consciousness and cannot select whether or not to receive the service of the accident handling service system, the accident handling service system must perform the accident handling service as described above. For example, the exact location of the accident cannot be determined, which can take considerable time. Of course, since the present invention uses GPS, it is possible to grasp the approximate location of the area where an accident has occurred by using the GPS location information, but it is currently impossible to accurately detect the location. Therefore, in order to solve this problem, the present invention uses the RF signal generated by the RF signal generator 170. Since the RF signal generator 170 continuously generates an RF signal of a predetermined frequency band when the driving is started, the vehicle dispatched for the accident handling service is first driven to a position corresponding to the position information by GPS, and then By tracking the RF signal generated by the RF signal generator 170, it is possible to easily reach the location of the accident vehicle.

In the above description, if the key of the user selection unit 155 is not input within a predetermined time after the text information display unit 160 and the voice generator 165 are driven, the RF signal generator 170 is operated. According to the present invention, the RF signal generator 170 may be configured to operate from the moment when the first information transmitter / receiver 150 wirelessly transmits the accident / breakdown of the vehicle to the accident processing service providing system. Those of ordinary skill in the art will readily know.

Specific operations of the transmitted accident processing service providing system shown in FIG. 1B are as follows.

When the self-diagnosis information of the vehicle, the current location information of the vehicle, and the vehicle ID information are transmitted through the wireless communication network, the second information transceiver 210 receives the transmitted information to receive a public switched telephone network (PSTN) or an Internet-only network. Through the restoration unit 220 through.

The restoration unit 220 decodes and outputs information received through a PSTN network or an Internet-only network into code data, and the user restoration information 220 includes a user selection information input unit 225 and a vehicle ID identification unit 230. The location information provider 235 and the accident grade determiner 240 are connected. Although the components 225, 230, 235, and 240 are illustrated and described as respective components for description, the components 225, 230, 235, and 240 may be configured as one processor together with the accident processing service control unit 250. Those who have knowledge will easily know.

The accident processing service control unit 250 is for receiving a signal indicating whether the driver of the accident vehicle receives the accident processing service as shown, the vehicle ID identification unit 230 is for receiving and identifying the vehicle ID data The location information providing unit 235 detects the current location using the current location data of the vehicle, that is, the longitude and latitude data, and the accident class determining unit 240 detects values detected by the ECUs and sensors of the vehicle. To determine the vehicle accident and failure class. The method of determining an accident grade in the accident grade determiner 240 will be described later in detail. In addition, the accident grade determiner 240 combines the information on the failure of the vehicle detected by the ECU 110 of the vehicle to determine the failure grade of the vehicle and provide it to the accident processing service controller 250.

As described above, when the accident grade information and the vehicle breakdown grade information are provided from the accident grade determiner 240, the accident processing service controller 250 receives the vehicle accident and the vehicle breakdown information and receives the accident handling service. The PSTN network 215 and the second information transmitter / receiver 210 provide a message to the vehicle self-diagnostic information transmission system. As described above, since the message is provided to the driver through the text information display unit 160 and the voice generator 165 of the vehicle, the driver may select whether to receive the service through the user selector 155.

The service selection information of the user selected by the user selector 155, that is, the user selection signal may be transmitted through the wireless communication network and the second information transmitter / receiver 210 and the PSTN network and restorer 220 as described above. Provided at 225, the accident handling service control unit 250 considers the driver to be unconscious if the user is provided with the information to receive the service or the information indicating whether the service is received from the driver within a predetermined time is not provided. The incident handling service must be performed.

That is, the accident processing service control unit 250 corresponds to the result by combining the current location information of the vehicle provided through the location information providing unit 235 and the accident rating and failure rating information provided from the accident rating determining unit 240. To determine the incident handling services, and provide the results to the incident handling agencies, such as insurance company 265, emergency center 270, maintenance company 275. It will be readily understood that such an agency and the incident processing service control unit 250 may be connected via a PSTN network or an Internet network as shown.

Specifically, the accident handling service control unit 250 is an accident handling service providing server, and has an insurance company, an emergency center, a maintenance company, and a database storing location information thereof for performing accident handling therein. Search for insurance companies, emergency centers, and maintenance companies that are closest to the location of the accident vehicle provided from the location information provider 235, and provide information to inform the searched companies of the occurrence of the accident and the handling of the accident. Provided through PSTN network or Internet network.

On the other hand, in the case of a failure of the vehicle, the accident handling service control unit 250 may notify the insurance company 265 and the maintenance company 275 of the occurrence of the failure, and may be regarded as an emergency at first. However, in case of an accident in the vehicle, the emergency center 270 should be notified in addition to this, and the emergency center 270 needs to respond appropriately according to the degree of the accident, so it is necessary to inform the extent of the accident in the vehicle. There is. To this end, a plurality of sensors 120 are attached to the vehicle of the present invention as shown in FIG. 1A, and the accident rating determining unit 250 determines the accident rating according to the information of the sensors and the information in the ECU 110. .

The present embodiment discloses a method of determining an accident grade using three pieces of information of a vehicle, that is, a collision part of a vehicle, a vehicle speed, and whether a seat belt is worn.

First, the degree of injury of the occupant is different depending on the collision direction of the vehicle. That is, the case where the front (A) of the vehicle shown in FIG. 2 collides with the highest degree of injury, the next is the case where the driver's seat and the driver's seat or the driver's back seat portion (B) collides, and the rear of the vehicle and the magnet behind the driver's seat (C). Injuries) are known to have a relatively low degree of injury. Therefore, in the present invention, in order to detect the collision direction during the collision of the vehicle, two sensors S1-S8 are respectively mounted on the front, rear, and both sides of the vehicle, so that the collision portion of the vehicle can be detected.

In addition, whether or not the seat belt is worn is a big factor in determining the degree of injury.

The company monitors each passenger's seatbelt, and the ECU also detects and provides vehicle speed information during a crash. In this embodiment, the risk of injuries that may occur when the vehicle collides according to the speed of the vehicle is classified into a, b, and c grades. When a grade is 0 to 40 km / h, the b grade is 41 to 80 km / h, Class c is set when the vehicle travels more than 81 km / h.

Injury information of drivers and passengers in the event of a vehicle crash can generally be predicted using the three factors mentioned above, namely, the collision area of the vehicle, the vehicle speed, and whether the seat belt is worn. As shown in Table 1, the degree of injury can be predicted.

Seat belt wearing speed Collision location Accident rating Not worn a A 2 Not worn a B 2 Not worn a C 3 Not worn b A One Not worn b B One Not worn b C One Not worn c A One Not worn c B One Not worn c C One Wearing a A 3 Wearing a B 3 Wearing a C 3 Wearing b A 2 Wearing b B 2 Wearing b C 2 Wearing c A One Wearing c B One Wearing c C One

In Table 1, accident grade 1 can be seen as a major accident ranging from serious to fatal, grade 2 can be seen as a personnel accident with a minor to severe injury and grade 3 as a personnel accident with a minor injury.

In the above-described example, only the collision information is used among the values detected by the sensors S1-S8, but when the sensors S1-S8 are configured to detect the collision force, the accident grade can be classified and classified according to the collision force. Could be. In addition, the above-mentioned example does not consider different safety facilities depending on whether the airbag is installed and the vehicle, but these elements may be considered as necessary. However, three factors in the present embodiment, namely, the collision part of the vehicle, the vehicle speed, and whether the seat belt is worn should be basically considered.

As described above, the vehicle self-diagnostic information transmission system according to the present invention provides information on the failure and vehicle accident of the vehicle to the accident handling service providing system, and the accident handling service providing system responds to the accident and failure of the vehicle. Providing appropriate accident handling services can not only prevent accidents, but also speed up post-processing for large accidents, thus protecting the driver's life and property.
