The driving analysis device 100 is communicatively connected with the ECU of the vehicle to receive various information about driving, and transmits the received information about driving of the vehicle to the central server 200 of the driving evaluation system of the present invention. corresponds to In addition, the operation analysis apparatus 100 communicates with the user terminal 10 in short-range communication, confirms the location of the user terminal 10, and receives operation information of the user terminal, for example, log information, It is configured to match the driving information and transmit it to the central server 200 .

The driving analysis apparatus 100 is an OBD, and may be communicatively connected to the vehicle in a wired or wireless communication environment. Since the vehicle is equipped with an OBD port for interfacing with an external device, it is recommended to form a connection terminal corresponding to this port in the operation analysis device 100 of the present invention and configure the connection terminal to be physically connected to the OBD port. desirable.

Considering the communication distance, transmission data size, vehicle mobility, etc., the vehicle operation information transmitted from the operation analysis device 100 to the central server 200 is 3G, Long Term Evolution (LTE), Long Range (LoRa) It may be transmitted using long-distance wireless communication such as In addition.

(160).

The external power unit 110 is a generic name of a component that receives vehicle power from the vehicle, for example, receives power from a power line adjacent to the OBD port of the vehicle, or is electrically connected to the vehicle's cigarette jack to supply power through this. can be supplied stably. For example, the external power supply 110 may include a circuit for applying power by being connected to a cigar jack of a vehicle by a cable. Meanwhile, the external power unit 110 may convert the vehicle power into one or more operating powers having a specified voltage and a specified amount of current. Meanwhile, the present invention is not limited thereto. Alternatively, the external power supply 110 may receive external power as a separate USB-based battery in addition to vehicle power.

The external power unit 110 may include a battery or a capacitor for charging power having a specified voltage and current amount based on the supplied vehicle power. For example, the external power unit 110 may charge power having a specified voltage and current amount for communication in BLE (Bluetooth Low Energy) mode with the user terminal 10 of the driving analysis device 100 . Also, according to the implementation method, it is possible to amplify the signal strength of the one-way wireless signal transmitted to the outside in the BLE mode at a certain rate compared to the BLE mode and charge the power having the set voltage and current amount for transmission. That is, the external power supply 110 is configured to manage power for stable operation of the operation analysis device 100 .

The ECU information receiving unit 120 is configured to receive ECU information about driving of the vehicle from the vehicle OBD port.

The ECU information receiver 120 records ECU data in a unit sequence of one driving from starting the vehicle to turning it off, and the ECU data includes vehicle information, vehicle driving speed (rpm), and accelerator/brake operation. , wheel rotation speed, engine and fuel system information, exhaust gas and boil-off gas status of the vehicle, whether the airbag shock device operates in an accident, coolant temperature measured in connection with various sensors, engine oil temperature, automatic transmission oil temperature, intake air It includes temperature, transmission oil temperature, intake air volume, TPS (throttle position sensor), ISA (idle speed actuator), steering wheel angle, ignition angle and fuel injection amount.

On the other hand, vehicle information includes serial information of the vehicle, and based on the serial information of the vehicle, it is possible to determine whether the vehicle's engine type, for example, gasoline, diesel, electric, or hybrid, and analyze driving information accordingly. have. On the other hand, in order to prevent the driving information from being distorted through the operation of the driving analysis device 100, it may be regarded as cheating that the serial information of the vehicle is changed based on the vehicle model information registered at the time of initial service subscription. may be

The ECU data includes the vehicle's driving speed (rpm), steering wheel operation, accelerator/brake operation, TPS (throttle position sensor), engine and fuel system information, vehicle exhaust status, and vehicle exhaust status from starting to turning off the engine. , it is possible to check the degree of safe driving by analyzing the data of the impact device of the airbag, and detect sudden start/sudden/sudden stops, and collision accidents.

For example, if the throttle is opened when the brake is pressed and the vehicle suddenly starts moving forward, makes a sharp turn, or stops suddenly, it can be managed with abnormal operation information, Voltage abnormality, lamp abnormality, and the like of electrical components may be managed as failure information, and airbag burst information of an airbag impact device may be managed as accident information.

The sensor information collecting unit 130 is configured to collect driving-related information of the vehicle 10 from the sensor in addition to the ECU information when the OBD port is connected through a self-sensor of the driving analysis device 100 . For example, the sensor information collection unit 130 includes a GPS reception function (GPS sensor), a 3-axis acceleration sensing function (gyro sensor), and the like, and obtains latitude/longitude/altitude as driving information for the vehicle 10 . It can measure and collect location information, including changes in acceleration. Specifically, the sensor information collecting unit 130 may receive vehicle position information and vehicle posture information while the vehicle is being driven. Corresponding information is reflected in the driving information, stored and managed, and the sensor information collecting unit 130 collects driving information periodically (eg, 1 second) while receiving power from the external power supply 110 . can

The information collected by the sensor information collecting unit 130 is stored as driving information together with the ECU data received from the ECU information receiving unit, which is matched with log information of user manipulation using a user terminal in a user terminal matching unit to be described later, It is used to determine whether the driver's driving habit and the owner of the user terminal match the actual driver. Meanwhile, matching with log information is matched according to the same time.

For example, by using an IoT communication function (eg, LTE Cat. M1) by an external communication unit, operation information may be matched with log information of a user operation using a user terminal and transmitted to the server, that is, the central server 200 . The sensor information collecting unit 130 ends the driving of the vehicle 10 from the time when the driving analysis device 100 starts receiving power from the vehicle 10 or when user authentication is performed through the user terminal. Until the time when the supply is stopped, the operation of transmitting the driving information collected by the sensor information collecting unit 130 to the central server 200 may be performed periodically.

For example, if continuous manipulations such as slides and clicks are performed through the user terminal at a specific time, and the steering wheel of the vehicle is operated on the driving information at the same time, the driving habit can be evaluated based on the information. , when the information manipulated by the other side is included at the same time even though either side requires both hands on the log record or driving information, it can be determined as a cheating act that the owner of the user terminal did not actually drive .

The driver identification unit 140 interlocks with the user terminal at the time when the driving analysis device 100 starts receiving power from the vehicle 10 , that is, at the start of driving, and receives a user authentication signal from the user terminal and registers it. It is configured to check whether the user is the specified user, and also to check whether the user terminal is located in the vehicle while the vehicle is running.

The driver identification unit 140 includes a user authentication unit 141 that receives user authentication verification information through biometric information through the user terminal 10 and a terminal location verification unit that determines whether the user terminal is located in the vehicle ( 143).

The user authentication unit 141 performs user authentication for pairing with the registered user terminal 10 when the driving analysis device 100 starts receiving power from the vehicle 10 after the user gets into the vehicle. When a request is made to the terminal 10 and user authentication is confirmed through the user terminal 10 , the corresponding confirmation information is received and pairing with the user terminal is performed.

The user authentication of the user authentication unit 141 may follow the authentication procedure registered by the user in the application on the user terminal managed by the driving evaluation system of the present invention. An authentication procedure may be performed for pairing with the driving analysis device 100 through execution of an application for a service, a vehicle sharing service, and the like. That is, there may be a form in which the user requests pairing to use the service on the application, or otherwise, when the registered user terminal 10 is detected after the operation analysis device 100 is powered on, the user for pairing It may be in the form of outputting a push for authentication to the user terminal 10 .

The user authentication may be performed through biometric information input from biometric sensors of the user terminal, for example, a fingerprint recognition sensor, an iris recognition sensor, a face recognition sensor, a voice recognition sensor, and a blood vessel recognition sensor. When the user authentication according to the biometric information is confirmed, the user authentication unit 141 receives the confirmation information and pairing with the user terminal 10 is performed.

Pairing by the user authentication unit 141 is a short-distance communication of an external communication unit, for example, any one module NFC (Near Field Communication) module, Bluetooth (Bluetooth) module, Wi-Fi (WiFi) module, RFID module and beacon (Beacon) You can use the selected module from among the modules.

The terminal location check unit 143 checks whether the user terminal 10 is located in the vehicle. In the case of the user authentication unit 141, while involved in pairing with the initially registered user terminal and the driving analysis device 100, the terminal location check unit 143 is the user terminal when the driver operates the vehicle. It is determined whether it is located in the vehicle. That is, the terminal location check unit 143 is intended to prevent cheating in which a driver attempts to pair by using a user terminal of a third party.

For example, the terminal positioning unit 143 determines whether pairing is maintained by short-distance communication, or detects a change in signal strength due to short-distance communication, so that the paired user terminal 10 is a vehicle Check whether my location is there or not. If the pairing is disconnected or the signal strength is weak, it is determined that the user terminal 10 is not located in the vehicle. and transmit cheating information.

The terminal information matching unit 150 is configured to receive log information about a user's manipulation of the user terminal 10 through the external communication unit 160, and to match it with driving-related data. For example, the terminal information matching unit 150 receives log information of the user terminal by the user while the user terminal 10 is paired with the operation analysis apparatus 100 .

That is, the user terminal 10 transmits log information on user actions to the operation analysis apparatus 100 . At this time, the user terminal 10 detects log information directly manipulated by the user, that is, log information allowed to be transmitted to the operation analysis apparatus 100 from among the log information of the user's actions, and transfers the detected log information to the operation analysis apparatus ( 100) can be transmitted. This is to protect personal information about information irrelevant to user manipulation. For example, the transmitted log information includes all information that may be generated by a user operation such as clicking a button on the user terminal, executing a specific application, unlocking a lock screen, user operation through a touch panel, and inputting a message.

The terminal information matching unit 150 is configured to communicate with the user terminal 10 in a short range, receive log information from the user terminal 10, match the operation information with the operation information, and transmit it to the central server 200 do. The matching matches the corresponding driving information and log information according to time.

The central server 200 may extract a driver's habit of operating the user terminal while driving, based on the corresponding information, and at the same time, the driving information and log information regarding the operation of the user who is the driver can coexist at the same time. If it is determined that it is impossible, it is configured to determine the cheating behavior of the driver.

For example, if continuous manipulations such as slides and clicks are performed through the user terminal at a specific time and the steering wheel of the vehicle is manipulated based on the driving information at the same time, log information based on the degree of manipulation or the time of manipulation Alternatively, when the operation information of the other side is included at the same time even though one side requires both hands manipulation on the driving information, it may be determined as a cheating act in which the owner of the actual user terminal does not drive. That is, it can be determined as cheating operated by another person through authentication of the passenger.

The external communication unit 160 transmits and receives information so that the operation analysis device 100 communicates with the user terminal 10 through short-range communication (Wi-Fi or Bluetooth) or a mobile communication network (3G/LTE), and the mobile communication network (3G) /LTE) is configured to communicate with the central server 200.

On the other hand, although the operation evaluation system according to the present embodiment has been described as an example of collecting operation information from the sensor of the operation analysis apparatus 100 , the present invention is not limited thereto. GPS information from the GPS sensor of the user terminal 10 and 3-axis acceleration sensing information from the gyro sensor may be extracted and transmitted to the driving analysis apparatus 100 . In addition, although it has been described as an example that log information matched with the driving information is transmitted to the central server 200 through the external communication unit 160 , the present invention is not limited thereto. For example, information may be transmitted from the operation analysis apparatus 100 to the user terminal 10 , and related information may be transmitted to the central server 200 by the user terminal 10 .

That is, according to the embodiments of the present invention, after user authentication through the user terminal, it is connected to the ODB device, and while collecting data from the ODB device, it is checked whether or not paired with the user terminal through short-distance communication, and collection It is possible to prevent cheating such as changing the driver by matching the data and the operation record of the user terminal to determine whether the user authenticated by the user terminal is the actual driver.

Hereinafter, the configuration of the central server will be described with reference to FIG. 4 .

FIG. 4 is a block diagram illustrating the central server of FIG. 1 .

1 to 4, the central server 200 is configured to analyze the user's driving habits based on the driving information received from the driving analysis device 100, and when cheating occurs at the same time, the cheating information is displayed. In addition, when it is determined that the coexistence of both information is impossible at a certain time from the log information matched with the driving information, it is configured to determine cheating and manage cheating histories for each user. Accordingly, the central server 200 includes a communication unit 210 , a customer management unit 220 , a driving habit analysis unit 230 , a cheat determination unit 240 , and a cheat processing unit 250 .

The communication unit 210 is configured to receive the driving information from the driving analysis device 100 through the network 5 . The driving information may be transmitted in real time, or the driving information may be collectively transmitted when the driving analysis device 100 is connected to power and then the engine is turned off and the power connection is terminated. In the latter case, the operation information may be transmitted using the reserve power or via the user terminal 10 . Also, when the driver cheats, such as attempting pairing, using a third-party user terminal, the communication unit 210 receives the corresponding cheating information. Corresponding information is configured to be accumulated, recorded, and managed by matching with customer information. In addition, it receives the identification number of the vehicle or the serial number of the operation analysis device.

In addition, the communication unit 210 communicates with the external server 300, analyzes big data of driving information, and transmits the analysis result of the driver's habit through the driver's driving pattern to the external server 300, and the external server It is designed to provide the necessary information. For example, in the case of an insurance service, vehicle operation information, breakdown information, abnormal operation information, and accident operation information are provided to an external server. can make it

On the other hand, the network 5 connecting the operation analysis device 100 and the central server 200 is a local area network (LAN), a wide area network (WAN), a value added network (Value Added) Network (VAN), Personal Area Network (PAN), mobile radio communication network, Wibro (Wireless Broadband Internet), Mobile WiMAX, High Speed Downlink Packet Access (HSDPA) or satellite network, etc. It can be implemented as a type of wired/wireless network.

The customer management unit 220 registers and manages at least one or more users who want to use the evaluation service for driving habits in the driving evaluation system as customers. For example, the customer management unit 220 is configured to communicate with the user terminal 10 and receive customer information including basic information through membership registration.

The customer management unit 220 stores and manages user information including basic information such as the user's name, contact information, and e-mail address input from the user terminal 10, and when the user registers as a member, the user is identified for each user. A code is assigned, matched with the input user information, and stored and managed in the customer DB.

In addition to the basic information, the user information may include driving habit information and cheating history information in the driving habit analyzer 230 to be described later, and information on using an external service subscribed to. In addition, when it is necessary to install the driving analysis device 10 in a vehicle that the user wants to use, for example, an insurance service, the customer management unit 220 provides the driving analysis device 100 purchased or issued by the user. It is configured to register and manage the serial code of Accordingly, the central server 200 may receive the serial code along with the driving information from the driving analysis device 100 to determine whether the user is a registered user.

The driving habit analysis unit 230 determines the movement path of the vehicle according to the GPS location of the vehicle by time based on the driving information, and determines the driving speed (rpm) of the vehicle, the mileage, the operation of the accelerator/brake, and the rotation of the wheel. Based on speed, engine and fuel system information, vehicle exhaust status, and vehicle position and posture, it stores safe driving information, abnormal driving information such as sudden start/abrupt turn, failure information, airbag collision detection, and accident records, It is configured to record the driving record and driving pattern of the vehicle by analyzing the speed/direction/posture of the vehicle for the big data of the driving record of the car according to the location of the vehicle.

That is, the driving habit analyzer 230 receives the driving information from the driving analysis device 100 , and analyzes the driving record of the vehicle by measuring the speed/direction/posture of the vehicle based on the driving information. One run is recorded as a unit sequence, and it can be uploaded to the central server 200 in the cloud in non-real time. Or, alternatively, it may be uploaded in real time. Accordingly, when accident/abnormal driving information is detected, or when cheating is suspected or confirmed, feedback information is transmitted in real time. The feedback information may be transmitted to the user terminal 10 or may be transmitted to an external server serving as a service used. For example, when an accident or the like is detected, an immediate rescue report and a report to an insurance company may be made.

That is, the driving habit analysis unit 230 records raw data (driving information) on the driving sequence of the vehicle for each GPS location of the vehicle for each customer time zone, and consists of a big data platform that collects and analyzes driving information, It provides an API that can be linked with an external server, and provides the vehicle driving record analysis result as a dashboard (Dash Board). Accordingly, the central server 200, the driving type of a group rather than an individual, driving characteristics by engine driving method (gasoline, diesel, electric, hybrid, etc.), driving characteristics by vehicle model, LBS (Location Based Service) based crossover analysis is possible.

Meanwhile, the driving habit analyzer 230 may analyze the user's driving habit in a pattern based on the received driving information based on artificial intelligence. For example, LSTM can be used because the process of driving a vehicle is time series data. An LSTM network may include a plurality of LSTM cell structures. That is, vehicle driving information may be input to an analysis model learned in advance as time series data, and driving situation information or driving habit information may be output. Meanwhile, the analysis model may include at least one analysis model optimized for an engine type or a vehicle type. That is, based on the vehicle identification code information, an optimized analysis model may be applied, and a driver's habit may be analyzed accordingly. Meanwhile, the analysis model may generate a DNN model that re-learns the analyzed result.

For example, the driving habit analyzer 230 may evaluate the driving habit of the driver by detecting a driving scenario as a pre-learned event occurring during the driving. For example, when at least one specific enumerated event vector learned in advance is obtained, the RNN detects at least one specific predicted driving scenario by applying one or more RNN operations to the specific enumerated event vector, It is possible to output the driving habit of the driver.

In addition, the driving habit analysis unit 230 first classifies based on the identification information of the vehicle transmitted along with the driving information, and further classifies and stores the driving information classified based on the identification information in more detail by time period or date. can When such classification and storage processing is completed, a driving evaluation index, which is an evaluation index for the driver's driving habits, is generated using the driving information.

The driving evaluation index is a sporty index indicating the amount of speed change of the vehicle using the vehicle speed information included in the driving information, brake operation information, and throttle operation information that controls the ratio of air and fuel flowing into the cylinder. and an Eco index indicating driving fuel efficiency. In addition, an environmental index indicating the driving environment may be included using the driving section information, driving distance information, and driving location information included in the driving information. As described above, since the driving information is classified and stored for each time zone or date, the above-described processing for generating a driving evaluation index using the driving information is also performed separately for each time zone or date. The driving evaluation index is digitized, accumulated and stored for each customer, and may be transmitted to the user terminal 10 of the customer at the time of the customer's request or update.

In addition, the driving habit analyzer 230 is configured to analyze the driver's driving habit outside of driving based on log information about the operation of the user terminal 10 provided together with the driving information. In this case, the driving evaluation index includes a safety index for insensitivity to safe driving when driving a vehicle. For example, based on the driving information, a user such as clicking a button on a user terminal, executing a specific application, unlocking a lock screen, user manipulation through a touch panel, inputting a message, etc. If manipulation occurs, the safety index may be underestimated. That is, a deduction may be given to a numerical value that is a safety index as much as the number of times a user manipulation occurs. In addition, based on the driving state, when the vehicle is stopped, moving, specifically, when moving at a low speed or high speed based on the vehicle speed, the safety index may be evaluated based on a difference.

The driving habit analyzer 230 analyzes the user's driving habits based on driving information for each driving, accumulates them, and stores and manages them for each customer.

The cheat determination unit 240 determines whether the collected information (operation information, etc.) provided from the operation analysis apparatus 100 is valid information in consideration of a cheating situation based on the operation information and log information. .

For example, the cheat determination unit 240 may be configured to, when log information matching the driving information of the vehicle 10 from the driving analysis device 100 cannot coexist, driving information provided from the corresponding driving analysis device 100 can be judged as cheating suspicion. That is, the cheat determination unit 240 determines that the vehicle is cheating when the driver and the owner of the user terminal do not match when driving is performed through identity authentication to the driving analysis device 100 using the passenger's terminal. , if a suspicious situation occurs with him, it can be judged as cheating.

For example, the cheat determination unit 240 includes information in a time zone in which the complexity of user manipulation is higher than a predetermined value in any one of the vehicle driving information and the log information, When user manipulation is included, it may be determined that coexistence is not possible. When manipulations such as slides and clicks are performed through the user terminal in a specific time period and the steering wheel of the vehicle is operated based on the driving information at the same time, the complexity of the user operation is high based on additional information such as the posture and speed of the vehicle Even in the case of manipulation information included in the log information, it may be determined that cheating is suspected. The opposite is also true. Contrary to this, although the user's manipulation is performed on the driving information, when the complexity of the user's manipulation is low, such as during a stop or a low-speed straight-line driving, even if the user's manipulation information is included in the log information, cheating is not suspected.

In addition, the cheat determination unit 240 determines that cheating is suspected when a continuous operation, not a one-time operation such as slide or click, is performed before or after a point in time when a user steering wheel operation is required on the driving information, or continuously for a certain period of time. can do.

The cheat determination unit 240 may count the number of times determined to be cheating with respect to the operation information provided from the operation analysis apparatus 100 . If the number of times determined to be cheating is greater than a predetermined number of times, it may be determined as cheating. Although the cheat determination unit 240 according to the present embodiment determines that the cheating is suspected as cheating if the number of times of cheating is greater than or equal to a certain number of times, it is described as an example, but the present invention is not limited thereto. For example, each behavior suspected of cheating may be determined and treated as cheating.

When it is determined that the cheating processing unit 250 is cheating, it transmits a warning message to the user terminal 10 of the customer matching the corresponding operation analysis device 100 or applies a penalty to the subscribed service. is responsible for For example, cheat information is provided to the external server 300 that manages the service system. On the other hand, if it is determined as cheating, the corresponding driving information is invalidated and is not used as data for analyzing the user's driving habits.

For example, when the driving information is determined to be cheating once, a cheating warning message may be transmitted to the user terminal 10 of the customer matching the corresponding driving analysis apparatus 100 . That is, when the driving analysis device does not match the identification code of the registered vehicle, when the driver attempts to pair the driving analysis device 100 with a third-party user terminal, the pairing with the user terminal is not maintained from the driving time. If not, based on the log information from the matching user terminal, when pairing with the passenger's terminal is suspected, it may be determined as cheating and a warning message may be transmitted to the user terminal 10 . Alternatively, since a warning sound output unit is provided on the operation analysis apparatus 100 , when it is determined as cheating, the operation analysis apparatus 100 may sound a warning sound.

The cheating processing unit 250 may apply a predefined penalty when it is determined that the driving information provided from the driving analysis apparatus 100 is cheating.

For example, when the external server is associated with an insurance service, it may be applied in the form of adding a penalty premium to a preset premium. Or, if it is related to car rental or sharing services, it may restrict the use of the service or require payment of a penalty fee.

Of course, the penalty applied by the cheating processing unit 250 may be applied in different forms depending on the type of service that utilizes driving habit evaluation as well as the penalty of the present invention. Also, from a cheating point of view, it is not directly related to driving, but may affect personal creditworthiness.

As described above, the central server 200 of the present invention, in consideration of the cheating situation, a feature function for determining whether the collected information (operation information, etc.) provided from the operation analysis device 100 is valid information. can be realized

According to various embodiments as described above, in the present invention, in consideration of a malicious cheating situation, the reliability of the evaluation of the user's driving habit calculated through the collection of information based on the implantable device (device) provided in the vehicle is secured to derive the effect For this reason, according to the present invention, reliable services can be provided in various services related to driver's driving habit evaluation, thereby improving service quality and further expanding the scope of service development can be expected.

It is a management server that manages a service system interworking with the operation evaluation system of the external server 300 . For example, the external server 300 may be a management server such as an insurance service or a vehicle sharing or rental service. In addition, it may be a credit evaluation server that manages personal credit for cheating history. In addition, it may be a taxi call service server that provides information on the driver's driving habits, and a proxy driving application service server. In this case, when the service user calls a taxi and calls the surrogate driving, the service user may make a call by referring to the driving habit information of the connected taxi driver or the surrogate driver or setting conditions.

That is, the external server 300 is configured to receive at least one of information about a customer's driving habit and cheating information from the central server 200 . Corresponding information may be transmitted to an external server according to a request from the external server or whenever it is updated. Accordingly, the central server 200 is configured to manage an external server for the service being used by each customer. That is, a plurality of external servers 300 may be configured according to services.

Hereinafter, a vehicle driving evaluation method according to an embodiment of the present invention will be described with reference to FIG. 5 . 5 is a flowchart illustrating a vehicle driving evaluation method according to an embodiment of the present invention.

1 to 5 , the vehicle operation evaluation method according to an embodiment of the present invention includes the steps of receiving vehicle operation information and log information (S100), and analyzing a driver's habit from the vehicle operation information (S200) , determining whether or not cheating from vehicle driving information and log information (S300), managing driver habits and cheating history for each customer (S400), and transmitting the requested information when requesting information from the outside (S500). .

In the step (S100) of receiving the vehicle operation information and log information, the central server 200 is configured to receive the operation information from the operation analysis device 100 through the network 5 . The driving information may be transmitted in real time, or the driving information may be collectively transmitted when the driving analysis device 100 is connected to power and then the engine is turned off and the power connection is terminated. In the latter case, the operation information may be transmitted using the reserve power or via the user terminal 10 . In addition, when the driver cheats, such as attempting pairing, using a third-party user terminal, the central server receives the cheating information. Corresponding information is configured to be accumulated, recorded, and managed by matching with customer information. In addition, it is possible to receive the identification number of the vehicle or the serial number of the operation analysis device.

In addition, the log information may be transmitted by matching the operation information from the operation analysis apparatus 100 or may be transmitted directly from the user terminal 10 . If the log information is directly transmitted from the user terminal 10 , the central server 200 matches the driving information with the log information for each time. Here, it is assumed that the user terminal 10 is a user terminal paired with the operation analysis device 100 .

In the step (S200) of analyzing the driver's habit from the vehicle operation information, the central server 200 determines the movement path of the vehicle according to the GPS location of the vehicle for each time period based on the operation information, and the driving speed (rpm) of the vehicle , mileage, accelerator/brake operation, wheel rotational speed, engine and fuel system information, vehicle exhaust condition, safe operation information based on vehicle position and posture, abnormal operation information such as sudden start/rapid rotation, failure information , Airbag collision detection, accident occurrence records are stored, and the vehicle's speed/direction/posture is analyzed for the big data of the vehicle's driving record according to the location of the vehicle to record the driving record and driving pattern of the car. do.

That is, the central server 200 receives the driving information from the driving analysis device 100, and analyzes the driving record of the vehicle by measuring the speed/direction/posture, etc. of the vehicle based on this. One run is recorded as a unit sequence, and it can be uploaded to the central server 200 in the cloud in non-real time. Or, alternatively, it may be uploaded in real time. Accordingly, when accident/abnormal driving information is detected, or when cheating is suspected or confirmed, feedback information is transmitted in real time. The feedback information may be transmitted to the user terminal 10 or may be transmitted to an external server serving as a service used. For example, when an accident or the like is detected, an immediate rescue report and a report to an insurance company may be made.

The central server 200 may first classify the vehicle identification information transmitted together with the operation information as a reference, and classify and store the operation information classified based on the identification information in more detail by time period or date. When such classification and storage processing is completed, a driving evaluation index, which is an evaluation index for the driver's driving habits, is generated using the driving information.

The driving evaluation index is a sporty index indicating the amount of speed change of the vehicle using the vehicle speed information included in the driving information, brake operation information, and throttle operation information that controls the ratio of air and fuel flowing into the cylinder. and an Eco index indicating driving fuel efficiency. In addition, an environmental index indicating the driving environment may be included using the driving section information, driving distance information, and driving location information included in the driving information. As described above, since the driving information is classified and stored for each time zone or date, the above-described processing for generating a driving evaluation index using the driving information is also performed separately for each time zone or date. The driving evaluation index is accumulated and stored for each customer, and may be transmitted to the user terminal 10 of the customer at the time of the customer's request or update.

In addition, the central server 200 is configured to analyze the driver's driving habits outside of driving based on log information about the operation of the user terminal 10 provided together with the driving information. In this case, the driving evaluation index includes a safety index for whether or not to focus on driving while driving the vehicle. For example, when a user operation such as clicking a button on the user terminal, executing a specific application, unlocking a lock screen, user operation through a touch panel, or inputting a message occurs, the safety index is low based on the driving information based on the driving information can be evaluated. In addition, based on the driving state, when the vehicle is stopped, moving, specifically, when moving at a low speed or high speed based on the vehicle speed, the safety index may be evaluated based on a difference.

In the step (S300) of determining whether to cheat from the vehicle driving information and the log information, the central server 200 receives the cheating from the driving analysis device 100 based on the driving information and the log information in consideration of the cheating situation. It is determined whether the collected information (operation information, etc.) provided is valid information.

For example, when log information matching the driving information of the vehicle 10 from the driving analysis device 100 cannot coexist, the central server 200 may can be judged as cheating suspicion. That is, the central server 200 uses the passenger's terminal to determine cheating when driving is performed through identity authentication to the driving analysis device 100, that is, when the driver and the owner of the user terminal do not match, If a suspicious situation arises with him, it can be judged as cheating.

For example, the central server 200 adds a vehicle's posture, speed, etc. when an operation such as a slide or click is performed through the user terminal at a specific time, and the steering wheel of the vehicle is operated on the driving information at the same time. Based on the information, even though the complexity of the user operation is high, when the operation information is included in the log information, both information cannot coexist and it may be determined as a cheating suspicion. In contrast, when user manipulation is performed on the driving information, but when the user's manipulation information is included in the log information at a point in time when the complexity of the user manipulation is low, such as while stopping or driving in a low-speed straight line, it is premised that both information can coexist. I don't suspect it's cheating.

In addition, the central server 200 may determine that cheating is suspected when a continuous operation, such as a slide, click, etc., is continued for a certain period of time before and after the time when a user operation is required in the operation information.

The central server 200 may count the number of times determined to be cheating with respect to the operation information provided from the operation analysis device 100 . If the number of times determined to be cheating is greater than a predetermined number of times, it may be determined as cheating. The central server 200 according to the present embodiment has been described as an example of determining cheating when the suspicion of cheating is more than a certain number of times, but is not limited thereto. For example, each behavior suspected of cheating may be determined and treated as cheating.

In the step of managing driver habits and cheating history for each customer ( S400 ), the central server is configured to store and manage driving habit information and cheating history information for each customer, and external service use information subscribed to as user information.

For example, when cheating is performed, a warning message is transmitted to the user terminal 10 of the customer matching the corresponding operation analysis apparatus 100 or a penalty is applied to a subscribed service. For example, cheat information is provided to the external server 300 that manages the service system.

For example, when it is determined that the driving information is cheating, a cheating warning message may be transmitted to the user terminal 10 of the customer matching the corresponding driving analysis apparatus 100 . That is, when the driving analysis device does not match the identification code of the registered vehicle, when the driver attempts to pair the driving analysis device 100 with a third-party user terminal, the pairing with the user terminal is not maintained from the driving time. If not, based on the log information from the matching user terminal, when pairing with the passenger's terminal is suspected, it may be determined as cheating and a warning message may be transmitted to the user terminal 10 .

In the step (S500) of transmitting the requested information when the information is requested from the outside, the external server 300 is configured to receive at least one of information about a customer's driving habit and cheating information from the central server 200 . Corresponding information may be transmitted to an external server according to a request from the external server or whenever it is updated. Accordingly, the central server 200 is configured to manage an external server for the service being used by each customer. That is, a plurality of external servers 300 may be configured according to services.

It is a management server that manages a service system interworking with the operation evaluation system of the external server 300 . For example, the external server 300 may be a management server such as an insurance service or a vehicle sharing or rental service. In addition, it may be a credit evaluation server that manages personal credit for cheating history. In addition, it may be a taxi call service server that provides information on the driver's driving habits, and a proxy driving application service server. In this case, when the service user calls a taxi and calls the surrogate driving, the service user may make a call by referring to the driving habit information of the connected taxi driver or the surrogate driver or setting conditions.

The driving evaluation method according to an embodiment of the present invention may be implemented in the form of a program command that can be executed through various computer means and recorded in a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, etc. alone or in combination. The program instructions recorded on the medium may be specially designed and configured for the present invention, or may be known and available to those skilled in the art of computer software. Examples of the computer-readable recording medium include magnetic media such as hard disks, floppy disks and magnetic tapes, optical media such as CD-ROMs and DVDs, and magnetic such as floppy disks. - includes magneto-optical media, and hardware devices specially configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like.
