On the other hand, even if the driving assist device is used, the situation may not be improved by the warning provided by the driving assist device when the driver is in a drowsy state or overspeed. In such a case, it is necessary to transmit this state to the outside, and it is necessary to use a terminal such as a mobile phone that the driver personally carries.

An object of the present invention is to provide various services to a driver of a vehicle with low power using a low-power broadband communication network as a terminal connected to a driving assist device and a GPS module installed in a vehicle to provide sleeping prevention and speed limitation services And a service terminal.

In order to achieve the above object, a service terminal according to the present invention is installed in a vehicle, and is connected to a GPS receiver and a driving assistance device (ADAS). A method of providing a drowsiness operation and an overspeed prevention service by a service terminal comprises the steps of: receiving vehicle state information from the driving assistance device; and determining, based on the vehicle state information received repeatedly, Determining whether the vehicle is in a drowsy driving state when it is determined that the drowsy driving state occurs more than a predetermined number of times within a predetermined time range; To the external control server through the Internet.

According to the embodiment, the service providing method of the present invention includes the steps of periodically receiving the position and speed of the vehicle from the GPS module; Determining that there is an emergency brake operation when brake operation information is included in the vehicle state information received from the driving assistance device and the speed of the vehicle checked by the GPS module changes rapidly before or after the time the brake is operated; ; Further comprising the step of determining that the operation state is the drowsy operation state when the quick break operation occurs more than a preset number of times within a predetermined time range, thereby generating the first operation monitoring information according to another condition.

According to another embodiment, the service providing method of the present invention includes the steps of periodically receiving the position and speed of the vehicle from the GPS module; Determining that the vehicle is overspeed when the speed of the vehicle is equal to or higher than a predetermined speed, and generating second operation monitoring information indicating that the vehicle is in an overspeed operation state and providing the second operation monitoring information to the control server.

The present invention is also applicable to a service terminal installed in a vehicle. The service terminal includes an LPWAN interface unit connected to a control server for managing information on a driver of the vehicle via a broadband low-power network, and a driving monitoring unit for generating the first operation monitoring information and the second operation monitoring information.

Service terminal

The service terminal 130 is a terminal connected to the LPWAN 150 through a wireless channel and installed inside the vehicle 10. [ The service terminal 130 of FIG. 2 shows an example in which the LPWAN 150 is a LoRa network.

The service terminal 130 needs to be implemented with a low power operation by using the LPWAN 150, minimizes data use so that the data communication fee is low, and consequently needs to minimize system resources. 2, the service terminal 130 includes a power supply unit 231, an LPWAN interface unit 233, and a MCU (Main Controller Unit) 250. Meanwhile, the service terminal 130 is connected to the GPS module 20 and the driving assistance device 110 according to the UART protocol.

The service terminal 130 transmits and receives data to and from the control server 170 and provides the sleepiness prevention and speed limiting service of the present invention to the driver. The service terminal 130 is connected to the LPWAN gateway 151 using the LPWAN interface unit 233 and the data transmitted to the LPWAN gateway 151 is transmitted to the control server 130 via the LPWAN 150 and the Internet 30. [ (170). The data provided by the control server 170 is also finally transferred to the service terminal 130 via the Internet 30 and the LPWAN 150. Therefore, in the following description, the expression that the service terminal 130 transmits data to the control server 170 or the expression that the control server 170 transmits data to the service terminal 130 is not limited to LPWAN 150 &quot;) and the Internet (30).

The power supply unit 231 provides DC operation power for operation of the service terminal 130. The power supply unit 231 may use the built-in battery, but may supply the DC power source V + of the vehicle 10 through the fuse box (not shown) of the vehicle 10 and supply the DC power source.

The LPWAN interface unit 233 has an antenna (not shown) and can communicate with the LPWAN gateway 151 through a wireless channel according to the LPWAN protocol. The LPWAN interface unit 233 provides the information provided by the MCU 250 to the control server 170 and receives the information provided by the control server 170 and provides the information to the MCU 250. [

The MCU 250 controls the overall operation of the service terminal 130 of the present invention and includes a operation monitoring unit 251 for the sleepiness prevention and overspeed limiting service of the present invention. The operation monitoring unit 251 may be software installed on a hardware chip called the MCU 250.

While the vehicle 10 is in operation, the operation monitoring unit 251 generates the operation monitoring information for the sleepiness prevention and speed limiting service of the present invention. The operation monitoring unit 251 provides the generated operation monitoring information to the control server 170 via the LPWAN 150 using the LPWAN interface unit 233. [

The operation monitoring information includes (1) first operation monitoring information for determining the driver sleeping state and / or (2) second operation monitoring information for determining whether the vehicle is overspeed. Hereinafter, the drowsiness operation and overspeed prevention service providing method of the present invention performed by the operation monitoring unit 251 will be described in detail with reference to FIG.

<Receipt of Vehicle Status Information and Operation Data: S301, S303>

The operation monitoring unit 251 periodically or non-periodically receives the vehicle status information from the driving assistant 110 (S301), and periodically receives the running data from the GPS module 20 (S303).

&Lt; Generation of First Operation Monitoring Information: S305 to S309 >

The operation monitoring unit 251 determines the first operation monitoring information generating condition. The first operation monitoring information is generated based on the vehicle status information provided by the driving assistance device 110 and the operation data provided from the GPS module 20. [ The lane departure event and / or the forward collision avoidance event are first detected in the first time range (for example, the first lane departure time, the second lane departure time, and the second lane departure time), as a result of checking based on the vehicle status information provided by the driving assistant 110, (For example, three times) within a predetermined period of time (e.g., five minutes), it is determined that the driver is driving the drowsy, and the first operation monitoring information is generated (S305).

According to another embodiment, the operation monitoring unit 251 may be set to the drowsy driving state even when the rapid brake operation event occurs at a second predetermined number (for example, twice) within a predetermined second time range (e.g., five minutes) It is possible to generate the report first operation monitoring information. The operation monitoring section 251 can confirm the operation of the rapid brake operation. The operation monitoring unit 251 determines whether or not the vehicle state information received from the driving assistant 110 includes brake operation information and that the speed of the vehicle checked by the GPS module 20 changes abruptly before or after the time the brake is operated It is determined that there is a rapid brake operation (S307).

The operation monitoring unit 251 provides the first operation monitoring information to the control server 170 (S309).

Since the first operation monitoring information informs the control server 170 that the driver is determined to be in the drowsy driving state, information indicating that the drowsy driving state is included may suffice. For example, the method of indicating the drowsy driving state may correspond to setting the drowsiness driving flag (Flag) to '1' in the LPWAN data provided by the operation monitoring unit 251 to the control server 170.

According to the embodiment, the first operation monitoring information may include the number of occurrences / occurrences of the lane departure event as a basis for judging the drowsy operation, the occurrence / occurrence frequency of the forward collision avoidance event, and the occurrence / have. Such information can also be transmitted in such a way that the corresponding flag is set or the number of times information is included.

In addition, the first operation monitoring information may include the running data (position, speed, direction information, etc.) of the vehicle 10. [ The vehicle location information can be used, for example, by the control server 170 to suggest a rest to the vehicle driver by informing the driver of the rest area in front of the vehicle.

&Lt; Generation of second operation monitoring information: S311 and S313 >

After steps S301 and S303 are performed, the operation monitoring unit 251 determines a second operation monitoring information generating condition. This determination may be performed before or after steps S305 to S309 are performed, but may be performed in parallel or simultaneously with steps S305 to S309.

The second operation monitoring information relates to whether or not the vehicle is overspeed, and the operation monitoring unit 251 determines whether or not the vehicle is overspeed based on the vehicle speed. At this time, the speed reference speed can be set to 'absolute speed reference speed' irrespective of the state of the road. For example, the 'absolute-speed reference speed' can be set to a speed determined to be overspeed on a highway that is allowed to travel at a high speed (S311).

If it is determined that the overspeed operation state is established, the operation monitoring unit 251 provides the second operation monitoring information to the control server 170 (S313).

The second operation monitoring information informs the control server 170 that the vehicle is judged to be under overspeed operation, so that it is sufficient if information indicating the overspeed operation state is included. For example, the method of indicating the overspeed operation state may correspond to setting the overspeed operation flag to '1' in the data provided to the control server 170. According to the embodiment, the second operation monitoring information may include the speed of the vehicle and the ACC status information as a basis for judging the overspeed operation.

In addition, the second operation monitoring information may include the running data (position, speed, direction information, etc.) of the vehicle 10. The vehicle location information can be used, for example, by the control server 170 to suggest a rest to the vehicle driver by informing the driver of the rest area in front of the vehicle.

On the other hand, since the second operation monitoring information can be generated when it is determined that the overspeed operation state is present, it is provided to the control server 170 irregularly.

In this way, the drowsiness operation and the overspeed prevention service by the operation monitoring unit 251 of the present invention are performed.

Example: Providing periodic second operation monitoring information

According to the embodiment, the operation monitoring unit 251 may periodically generate the second operation monitoring information and provide the second operation monitoring information to the control server 170. The second operation monitoring information generated periodically includes vehicle driving data (position, speed, direction information, and the like) and ACC status information, and includes information indicating an overspeed state if the vehicle is in an overspeed state. For example, the control server 170 can determine whether the vehicle driver is continuously driving for a certain period of time based on the second operation monitoring information periodically provided, and is continuously operating for a predetermined reference time (for example, four hours) An event can be performed that sends a message suggesting a break to the driver.

Embodiment:

The control server 170 manages various LPWAN services by the service terminal 130 of the present invention as a whole and registers and manages a driver for its operation. Through the driver registration, the control server 170 stores and manages the terminal identification number and the driver information by matching each other. Here, the driver information includes basic information such as a driver identification number, a login ID and a password, and a car number, as well as a telephone number, a MAC address, and the like of the driver portable terminal 190.

Here, the LPWAN service may be any type and type of service that can be performed by the interaction between the service terminal 130 and the control server 170 by exchanging LPWAN service data. The service proposed in the present invention monitors a speeding state of a vehicle and a drowsy driving state of a vehicle driver and sends a warning message to the driver's portable terminal 190 or a telephone to prevent overspeed driving or drowsy driving. For this purpose, the control server 170 includes a control processing unit 171. [

The control processing unit 171 receives the second operation monitoring information and the first operation monitoring information provided by the service terminal 130 and performs operations related to the drowsiness prevention and speed limitation service included in the LPWAN service. The control processing unit 171 can confirm whether or not the vehicle 10 has started its operation and terminated its operation through the second operation monitoring information provided by the service terminal 130. The drowsiness driving and overspeed prevention service And is provided when the vehicle 10 is in operation.

During the operation of the vehicle, the control processing unit 171 confirms whether the 'first and second operation monitoring information' is transmitted from the service terminal 130. The control processing unit 171 determines that the vehicle 10 is in an overspeed state when receiving the second operation monitoring information from the service terminal 130 and receives the first operation monitoring information, ) Is judged to be in the drowsy driving state.

In the overspeed operation and drowsy driving state, the control processing unit 171 can automatically transmit a predetermined warning message to the mobile phone of the vehicle driver. However, it may be difficult to confirm the message in the drowsy driving state, and the message check may cause other accidents during the overspeed operation.

In addition, the control processing unit 171 may transmit a predetermined type of message to an outside organization such as a police station or other road traffic safety bureau to deal with it.

Alternatively, another control agent may call the driver directly to wake up sleeping on the basis of the information provided by the control server 170, and propose to take a break at a rest area in front of him.

Example: connection of a GPS receiver on behalf of a GPS module

The GPS module 20 of FIG. 2 is an example of receiving the GPS signals from the GPS satellites and directly calculating the running data (position, speed, traveling direction, etc.) of the vehicles and providing them to the service terminal 130. However, instead of the GPS module 20, a GPS receiver that receives only the GPS signal may be provided. At this time, the service terminal 130 may directly calculate the vehicle operation data by receiving the GPS signal from the GPS receiver. However, in order to minimize the power consumption of the service terminal 130 and to prevent the price from becoming high, A black box in which the auxiliary device 110 or the driving assistance device 110 is built may be performed.

At this time, the service terminal 130 must transmit a signal of the GPS receiver to the driving assistant 110, and may further include a connection controller (not shown). In this case, the connection control unit (not shown) may be a software module installed in the MCU 250, like the operation monitoring unit 251.

The connection control unit (not shown) receives the GPS data from the GPS receiver on behalf of the driving assistance device 110 and intermediates the driving assistance device 110. As shown in FIG. 4, the connection control unit (not shown) may be implemented integrally with the service terminal 130 in a black box 400 or the like together with the driving assistance device, It is unnecessary when the GPS receiver 130 directly calculates the speed and / or the position of the vehicle 10 using GPS data. When the black box 400 having the driving assistant 110 or the driving assistant 110 has only one UART port for connecting only the GPS receiver, the corresponding port is connected to the service terminal 130, (20) is connected to the service terminal (130), a connection control unit (not shown) is required.
