The user information may include at least one of the vehicle identification number, the OBD unique number, the driver's telephone number, and the login ID.

In step S12, an alert notification received from the emergency recovery service server can be popped up on the monitor of the call center.

In step S13, after confirming the accident at the call center, the driver can be confirmed by telephone. Alternatively, if the driver calls the call center directly in the event of an accident, the database server confirms the user information matched with the driver's phone number, and pops up the pop-up of the accident among the information related to the driver on the call center monitor . At this time, the emergency recovery service interworking server is interlocked with the database server, and the vehicle identification number, the OBD number, the login ID, and the driver's telephone number may be mapped to the database server.

In step S14, an accident can be accepted to the fire department 119 and the insurer.

For example, when the vehicle's unique number is '1234', the OBD unique number is 'ABCD', the login ID is 'Hongdil Dong', and the driver's phone number is '010-1234-5678' Information may be transmitted from the vehicle terminal app of the in-vehicle computing device to the emergency recovery service interworking server.

In the event of an accident, the driver can inform the call center of the occurrence of the accident through the call center. At this time, the call center can automatically obtain the driver's telephone number of the driver. In the call center, the database server may receive information on a vehicle accident corresponding to the vehicle unique number mapped to the driver's telephone number (ex: 010-1234-5678) and display the information on a monitor. This is possible because the user information, the GPS information of the vehicle, and the accident image or the accident image taken by the mobile phone application are already received from the call center. After confirming the accident at the call center, the fire department or insurance company can receive the accident.

Or, in case of an accident, the call center can receive the accident occurrence user information from the emergency recovery service interworking server. At this time, the accident information including the user information is popped up on the call center monitor. After the accident information is confirmed in the call center, the database server searches the driver's telephone number matching with the user information and tries to communicate with the driver. Thereafter, an accident can be accepted from the call center to the fire station or the insurance company.

Figure 4 illustrates a remote start smart key provided in accordance with an embodiment of the present invention.

The remote start smart key may be provided via the remote start control mobile app of user computing device 15. [ The remote start control mobile app may be provided with a door lock / release button 41, 42 and a start START / STOP button 43 as shown in FIG. The door of the vehicle can be locked / unlocked remotely through the door lock / unlock button, and the engine of the vehicle can be turned on / off remotely via the start / stop button.

The remote start control mobile application may be the same as the user mobile application 16 in FIG. 1, or may be a separate application.

The control information generated by operating the remote start-up control mobile app may be transmitted to the on-vehicle computing device 13 by the user computing device 15. The vehicle computing device 13 may provide the received control information to the vehicle diagnostic module (OBD) 11 via the conversion device 12. [ The vehicle diagnostic module 11 may be capable of controlling the state of the vehicle based on the provided control information. For example, when the control information is a signal for starting, the start-up of the vehicle can be performed through operation of the remote start control mobile app.

5 illustrates a remote monitoring alarm viewer provided in accordance with an embodiment of the present invention.

The remote surveillance alarm viewer may be provided via a remote surveillance / image verification mobile app (user mobile app) of the user computing device 15. The vehicle mobile app 14 of the in-vehicle computing device 13 may store image information photographed outside the vehicle. The photographing may be performed by using a camera module built in the vehicular computing device 13. When the vehicle computing device 13 recognizes an accident, the vehicle computing device 13 may transmit the image information to the user mobile application 16 of the user computing device 15. [

Such an accident may mean an accident that occurred when the vehicle was stopped, that is, when the vehicle was parked. Whether or not the accident has occurred can be determined by detecting an impact applied to the vehicle. Information on the impact applied to the vehicle can be obtained from an acceleration sensor built in the vehicular computing device 13. [ Or the information about the impact applied to the vehicle may be acquired by the vehicle diagnostic module 11 and provided to the vehicle computing device 13 via the conversion device 12, It is possible. Alternatively, when the pixel change of the current frame and the previous frame is calculated at regular intervals and the pixel change continuously occurs more than a predetermined number of times, it may be recognized that the vehicle is impacted.

When the shock is detected, the vehicular computer device 13 may switch to the motion detection mode, store the image data, and send an alarm to the user mobile application 16.

For example, the user alarm sending sequence can perform the following steps.

In step S100, the parking mode can be started.

In step S101, the input image data may be stored in the image capture frame buffer.

In step S102, it is possible to determine whether an impact is detected and the impact-sensing image data is being stored in the frame buffer. At this time, if an impact is detected, an alarm can be sent to the user's mobile app in step S105. If no shock is detected, step S103 may be executed.

In step S103, it is possible to determine whether the number of pixel changes of the current frame and the previous frame is larger than the predetermined value. At this time, if the number of pixel changes is smaller than the predetermined first value, the process may return to step S101. If the pixel variation number is larger than the predetermined first value, step S104 may be executed.

If it is determined in step S104 that the number of pixel changes is greater than the predetermined first value continuously, it may be determined whether the number of consecutively generated pixels is greater than a predetermined second value. If it is determined that the number of consecutive occurrences is greater than a predetermined second value, step S105 may be performed. At this time, in step S105, the storage of the sensed image data may start. If it is determined that the number of consecutive occurrences is less than the predetermined second value, the process may return to step S101 and each step may be repeatedly performed.

When the step S105 is executed, the motion detection mode may be stopped and the parking mode may be switched after a predetermined time.

6 is a diagram illustrating a process of extracting abnormal information using a vehicle diagnostic module according to an embodiment of the present invention.

 The vehicle diagnostic module 11 can provide information such as steering angle (steering wheel turning angle) information, vehicle speed / acceleration information, brake signal information, and RPM information. The information may be transmitted to the onboard computing device 14 via the Bluetooth module 17 included in the conversion device 12 connected to the vehicle diagnostic module 11. [

The in-vehicle computing device 14 may include a Bluetooth module 18 adapted to be paired with a Bluetooth module 17. The vehicle mobile app 14 may be configured to display a current operational pattern state by applying a driver state analysis algorithm based on information received from the conversion device 12. [ Types of the operation pattern state may include 'normal operation', 'drowsy driving', 'drunk driving', 'overspeed driving', and 'vehicle abnormality'. Each operation pattern state can be displayed in different colors or different shapes.

FIG. 7 is a table showing an abnormal operation analysis standard according to an embodiment of the present invention.

When the driver starts driving, the average value based on the reference point as shown in FIG. 7 can be obtained for a predetermined time (for example, 5 minutes) at the start of the operation. At this time, if the average value changes by 25% or more, the driver may be notified.

The operation type can be classified into general speed, acceleration / deceleration, and rotation factor.

At this time, the acceleration and deceleration can be further subdivided according to the operation mode. For example, it can be divided into rapid start, rapid acceleration, sudden stop, and rapid deceleration. Which type of operation is applicable can be determined based on the acquired value after obtaining the speed and acceleration value.

In the case of rotation, it can be further subdivided according to the operation mode. For example, it can be classified as a class change, a change to a continuous class, and a sudden left or right turn. Which type of operation corresponds to which CPU, speed & acceleration value, and steering angle value can be obtained and then determined based on the acquired value.

In the case of a pattern having a normal speed, it may mean a normal driving situation. In the case of a pattern having acceleration or deceleration, a similar pattern may be displayed according to the habit of the driver. Therefore, if the average value of the speedometer changes for the above-mentioned 5 minutes, it can be determined that the situation is abnormal. Even in the case of the lateral acceleration pattern at the time of rotation, a similar pattern can be displayed according to the habit of the driver as in the acceleration or deceleration pattern. That is, if the average value of the lateral acceleration changes for the above-mentioned five minutes, it can be determined that the abnormal condition is present.

FIG. 8 illustrates a method of detecting abnormal status intervals according to an embodiment of the present invention.

The abnormality can be determined using the speed, acceleration, steering angle, brake signal, accelerator position sensor information, etc. of the vehicle diagnostic module (OBD) The abnormal situation may mean, for example, drunk driving and drowsy driving.

A dangerous driving reference point can be set using the information. As described above, it is possible to use the fact that unnecessary acceleration / deceleration and an abnormal steering angle are generated in the case of operation in an abnormal situation.

The graphs 80 to 82 show information on the road running acceleration information, the acceleration / gyro sensor information, and the right-handing during left curve driving, respectively. Based on such information, the running data graph 83 for rapid acceleration, rapid deceleration, left turn, and right turn can be obtained. Then, a final graph 84 for detecting an abnormal situation section can be obtained by using each running data graph 83. FIG.

In case of drowsy driving,

First, it can be analyzed through the amount of change of the accelerator pedal and the change of the vehicle speed. At this time, if an unnecessary acceleration / deceleration is confirmed, it may be a drowsy operation.

Second, it can be analyzed through acceleration increase versus speed increase. At this time, if the acceleration increase amount is larger than the speed increase amount, it can be recognized as a drowsy driving operation. That is, in the drowsy operation, the acceleration period may be shorter than the speed variation.

In the case of drunk driving,

First, it can be analyzed through the amount of change of the accelerator pedal and the change of the vehicle speed in the same manner as the drowsiness operation. At this time, if abnormal acceleration / deceleration is confirmed, it may be drunk driving.

Second, if the amplitude of the drowsiness operation is repeatedly long, it can be recognized as the drunk driving. That is, if the speed change is synchronized with the acceleration change and the acceleration / deceleration is repeated, it can be recognized as the drunk driving. This phenomenon may be caused by unnecessarily stepping on the brakes.

According to an embodiment of the present invention, an accurate maintenance service model based on a failure code can be implemented using a vehicle diagnostic module (OBD). That is, when a fault code of the vehicle is generated through the vehicle diagnostic module (OBD), it is displayed and the fault code can be transmitted to the maintenance specialist center separately from the user display. Then, a professional mechanic can provide a service for distinguishing the breakdown history, making a separate telephone call to the user, and inducing the vehicle wearing and maintenance to prevent an accident caused by a breakdown. Alternatively, it may be determined whether the recall information corresponds to the user's vehicle, and a service for uploading the vehicle information may be provided.

The smartphone according to an embodiment of the present invention may be a used smartphone, and the image black box function and the operation information analysis alarm function may be implemented using the used smart phone. In other words, the smartphone can function as a video black box without a separate black box, and it is possible to transmit the police information server information and abnormal operation (drowsiness, drinking, etc.) A warning alarm support model can be implemented.

Also, according to an embodiment of the present invention, self-diagnosis and maintenance of the vehicle condition can be performed during operation. That is, the vehicle function can be controlled through the OBD data receiver attached to the vehicle and the fuel economy driving can be induced.

Also, an E-call emergency rescue service model can be implemented through an embodiment of the present invention. For example, it is possible to model and provide an emergency response service capable of automatically notifying a rescuer and an insurance company of an occurrence of an accident such as an air bag deployment during driving.

In addition, as described above, it is possible to implement a remote start smart key using an inexpensive used smart phone and an OBD. For example, a smart car function service such as opening / closing of a vehicle door and restart control through an immobilizer is modeled .

In addition, according to the present invention, it is possible to implement a remote vehicle alarm function. In other words, it is possible to model and provide an expensive car alarm function implementation with only a low-priced smartphone and OBD.

Generally, in order to utilize the function of the smart car, it is necessary to purchase a vehicle equipped with the function, or to install expensive equipment. According to an embodiment of the present invention, Function can be utilized.

According to an embodiment of the present invention, a used smart phone can be used through data sharing.
