As shown in Fig. This control flow may be performed by driving the program and preferably generates a program (e.g., so-called firmware) and guide information provided in the vehicle information terminal 300, which is driven by the processor included in the electronic control unit 400 (For example, an application) for outputting the program.

First, the vehicle information terminal 300 receives the GPS signal (refer to (1) in Fig. 4) through the GPS unit 303 or the like, and determines the current position of the vehicle from this (see Fig. This process can be repeatedly performed, and it is possible to determine the current position including the latitude and longitude of the vehicle in accordance with the reception of the GPS signal, and further determine the current time. The control unit 317 of the vehicle information terminal 300 can determine the current speed of the vehicle from the repeatedly determined current position and the current time.

On the other hand, the electronic control unit 400 generates a plurality of state data (see? In Fig. 4) to be output from the sensor data received from one or more sensors in the vehicle through the OBD interface. The state data thus generated is data that allows the user to know the current driving state of the vehicle and the like.

Thereafter, the electronic control unit 400 outputs the plurality of status data (see 4 in Fig. 4) through the OBD interface and the vehicle information terminal 300 receives the plurality of status data through the vehicle interface unit 301 do. The plurality of state data enables the state of the current vehicle to be known.

The control unit 317 of the vehicle information terminal 300 that has received the plurality of status data sets the information about the vehicle based on the status data of the vehicle for warning or guidance to the driver of the vehicle based on the received plurality of status data (See 5 in Fig. 4).

Such guide information is output (refer to ⑥ in FIG. 4) to the output interface of the vehicle information terminal 300 through the output interface unit 313.

Such guidance information may be a guidance message composed of characters and displayed in the form of an image on the display of the vehicle information terminal 300 or further stored in the storage unit 315 of the vehicle information terminal 300 A program that performs a TTS (Text-to-Speech) function can be used to convert a voice or a voice generated based on stored voice data to a speaker.

As one example, the generation of the guide information and the outputting of the guide information may be performed by the mission control unit 400, which outputs the mission position (D, R, 1, 2, 3, The control unit 317 generates a guidance message such as "confirm the wide-angle rearview mirror ", etc., and displays it on the display Or through the speaker using the TTS function.

Alternatively, the control unit 317, which receives the mission state data and receives the accelerator position state data indicating the vehicle's accelerator position, can determine whether or not the vehicle has started to start from the combination of the two state data .

For example, when the numerical value of the acceleration position state data starts from 0% and increases with time and the mission state data is in the drive D state, the control unit 317 can determine to start the vehicle. Accordingly, when the vehicle has departed, the control unit 317 can generate a guidance message and output it as guidance information. Such a guidance message may be, for example, a message such as "confirm that all the seats are seated ".

In this starting process, the control unit 317 can generate another guidance message based on the other status data and output it as guide information. For example, the control unit 317 can determine whether the door lock is locked The door lock state data and / or the door open / close state data indicating whether the door of the vehicle door is opened or closed, and determines whether the current door lock is in the locked state and / or the door is closed Unit 317 can determine.

Accordingly, when the door lock is in the unlocked state or the door is open, the control unit 317 outputs a guidance message indicating such a state through the output interface unit 313 to allow the driver to issue a warning for safe driving compliance Can be output.

As another example, the control unit 317 may determine whether or not the vehicle is stopped or stopped based on the combination of at least one of the mission state data included in the received plurality of state data, the accelerator position state data, And generates a guidance message as guide information according to whether the vehicle is stopped or not, and outputs the guidance message to the output interface unit 313. [

For example, the control unit 317 determines that the vehicle is stopped when the mission state data is located on the parking P or the accelerator position state data is located at 0% where the accelerator is not pressed and further the speed state data is 0 km / h , And a guidance message such as "turn on the emergency light during the stop" can be output as guide information according to this determination.

In this way, the control unit 317 outputs guidance messages or warning messages for performing safe driving during driving or stopping by using one or more state data so that safe driving can be performed by outputting guidance information.

On the other hand, when identifying the case where the position of the vehicle determined from the GPS signal is within a designated area such as a school zone, the control unit 317 sets the speed state data, which is one of the plurality of state data, The guidance information can be generated.

For example, the control unit 317 maps the position of the vehicle, which is stored in the storage unit 315 or the like, or determined using the map data received from the vehicle information collection server 100, to the map data, It is possible to determine whether the position is a school zone area and to compare the speeds from the speed state data previously specified in the school zone area to generate guidance information for observing the safety speed.

Through such a configuration, it is possible to perform safe operation even in an area where GPS signals do not reach (for example, Jihwa tunnel).

In addition, the control unit 317 generates state control data in accordance with the determination as to whether or not the vehicle is to be stopped or whether to start the vehicle (see Fig. 4), and transmits the state control data to the electronic control unit 400 See ⑧).

For example, when the control unit 317 determines that the vehicle is stationary, the control unit 317 generates state control data capable of controlling the emergency light of the vehicle and transmits the state control data via the OBD interface of the electronic control unit 400, It is possible to generate the state control data for automatically locking the door lock and transmit it through the OBD interface.

Of course, in this process, the control unit 317 may also generate and transmit the state control data considering the value of the emergency light state data indicating the current lighting state of the door lock state data or the emergency light.

Thereafter, the electronic control unit 400 generates control data (refer to 9 in Fig. 4) for controlling the door lock or the emergency light in the electronic control unit 400 according to the received state control data, 4) ⑩).

Through the control flow as described above, the driver can safely drive the vehicle.

Fig. 5 is a diagram showing an exemplary control flow between apparatuses that enables the state of the vehicle to be shared in accordance with receipt of the state data of the vehicle. Fig.

 This control flow may be performed by driving the program and preferably includes a program (e.g., so-called firmware) running on the processor provided in the electronic control unit 400 and vehicle status information provided in the vehicle information terminal 300 (For example, an application) for generating and outputting the vehicle information, a program (for example, an application) of the user terminal 600, or a program of the vehicle information collection server 100.

Here, a description will be given in a range not overlapping with Fig.

First, the vehicle information terminal 300 (the control unit 317) determines the current position of the vehicle through the data from the vehicle information collecting apparatus 500 or the GPS signal through the GPS unit 303 (see (1 in Fig. 5) And receives sensor data from the sensor interface unit 307 or the vehicle information collecting apparatus 500 (see (2) in FIG. 5). This process is repeated periodically so that the current position and current vehicle status can be known.

On the other hand, the electronic control unit 400 generates a plurality of state data (see? In Fig. 5) and transmits it to the vehicle information terminal 300 (see Fig.

Accordingly, the control unit 317 of the vehicle information terminal 300 can receive one or more status data that allows the status of the vehicle to be known through the OBD interface and identify the status of the vehicle based on the one or more status data (See Fig. 5 ⑤) and transmits it to the vehicle information collection server 100 (see Fig. 5 ⑥).

As one example, the control unit 317 of the vehicle information terminal 300 may acquire the RPM status data indicating the current RPM (Rotation Per Minute) of the vehicle included in the plurality of status data, the speed status data indicating the current speed and / Or the accelerator position state data, and generates driving state information indicating the current driving state of the vehicle driver such as rapid acceleration, rapid deceleration, high RPM, overspeed, idling or the like by a combination of the state data, And transmitted.

For example, it is possible to determine whether the change (rate) of the speed state data is equal to or greater than a specified threshold value continuously in time, whether rapid acceleration or deceleration or the like, and determine the overspeed or the like as to whether the current speed state data is within the designated speed .

Such driving state information makes it possible to know driving habits of the driver of the vehicle. An operator or the like who recognizes such driving state information can warn the driver.

The vehicle state information including the driving state information may further include at least one state data received via the electronic control unit 400 and position information of the current position determined by the control unit 317. [ The status data may be, for example, speed status data that allows the current speed of the vehicle to be known.

As another example, the control unit 317 of the vehicle information terminal 300 may receive one or more sensor data measured from the sensor interface unit 307 or the vehicle information collecting apparatus 500, Environment state information included in the vehicle state information, and transmits the generated environmental state information to the vehicle information collection server 100. [

The sensor 309 may be a temperature sensor, an acceleration sensor, a malodor sensor, or the like. Depending on the environmental condition information, it may be determined how much the current temperature of the vehicle is, how much the vehicle is moving (for example, To allow operators or other users to know if smoke or smoke is bad.

Thereafter, the vehicle information collection server 100 receives the vehicle state information (refer to? In Fig. 5).

The vehicle information collection server 100 that has received the vehicle state information can also determine whether the speed of the vehicle is currently in compliance with the speed state data included in the vehicle state information and the position information .

For example, the vehicle information collection server 100 can determine the speed (restriction speed, etc.) to be observed at the current position and compare with the current speed state data to determine whether it is within the limit speed. If the vehicle is moving at a speed higher than the limit speed, the vehicle information collection server 100 may generate and transmit request information for reducing the speed to the vehicle information terminal 300 to a speed limit. Accordingly, the vehicle information terminal 300 may output the warning message through the output interface unit 313 according to the received request information as guide information or the like.

Thereafter, the vehicle information collection server 100 generates guide information to be used in the user terminal 600 (refer to 8 in Fig. 5) based on the received vehicle state information.

The guide information may be guide information configured to be used in the user terminal 600, including, for example, the current position of the vehicle, the vehicle speed at the current position, the environmental condition in the vehicle, and the driving habit of the vehicle driver .

Then, the vehicle information collection server 100 transmits the guidance information generated by the one or more user terminals 600 designated for the vehicle information terminal 300 of the received vehicle status information (see 9 of FIG. 5) 600 can display the guide information by using an app of the user terminal 600 or the like.

Through such a control flow, it is possible to share various status information related to the safety and environment of the vehicle with the operator or the user so that it can be conveniently grasped and guided by the management of the movement of the vehicle, the compliance of safe driving, and the driving propensity of the driver do.

4 and 5, an individual control flow for outputting the guidance information and sharing the vehicle state has been described. 4 and 5 are separately described for the sake of explanation, but the present invention is not limited to this, and FIGS. 4 and 5 are constituted by a single control flow, so that output of guidance information and sharing of the vehicle state are progressed .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings.
