[0035] Figure 1 is a block diagram of a system according to an embodiment disclosed herein.

[0036] Reference Figure 1 , a system 10 according to an embodiment of the present disclosure may include a vehicle 100 , a data collection device 200 , and a cloud server 300 .

[0037] Vehicle 100 may be an electric vehicle (EV) driven by a battery that stores electricity, but the scope of the present disclosure may not be limited thereto, and the technical spirit of the present disclosure may be applied to electric vehicles other than vehicle 100 (e.g., electric scooters, etc.).

[0038] The vehicle 100 may include a battery pack 110 , a vehicle controller 120 , and a vehicle network 130 .

[0039] The battery pack 110 may include a battery storing power required to drive the vehicle 100 and a battery management system (BMS) for controlling the operation of the battery. The BMS may control the charging / discharging of the battery and transmit battery status data to the vehicle network 130, the vehicle status data including at least one of data obtained by sensing the status of the battery (e.g., voltage, current, resistance, temperature, etc. of the battery) and data generated by processing the obtained data (e.g., state of charge (SoC), state of health (SoH), etc.). The vehicle controller 120 may communicate with another device inside or outside the vehicle 100 through the vehicle network 130.

[0040] The vehicle controller 120 may control the overall operation of the vehicle 100 by controlling the battery pack 110, at least one sensor (e.g., radar sensor, temperature sensor) and at least one control device (e.g., drive device, brake, steering device, automatic driving system (ADS), telematics multimedia system (TMS)) provided on the vehicle 100. According to another embodiment, the vehicle controller 120 may mean an electronic control unit (ECU) for controlling some components of the vehicle 100.

[0041] The vehicle network 130 may provide a communication environment in which the internal components of the vehicle 100 can send and receive data to and from each other. The vehicle network 130 may be a controller area network (CAN) in which the internal components of the vehicle 100 connected in parallel without a host can communicate with each other, but the scope of the present disclosure is not limited thereto. The vehicle network 130 may provide an environment that allows an external device (e.g., the data collection device 200) to access and communicate with another device (e.g., the battery pack 110) through the vehicle network 130.

[0042] The data collection device 200 may be installed on the vehicle 100 to access the vehicle network 130, and may be, for example, an on-board diagnostic (OBD) device connected to an on-board diagnostic OBD port provided in the vehicle 100. The data collection device 200 may access the vehicle network 130 and transmit and receive unified diagnostic service (UDS) data to obtain vehicle status information about the status of the vehicle 100 from internal components of the vehicle 100. Here, the vehicle status information may include speed data, driving distance data, driving time data, driving location data, and battery status data of the vehicle 100. The data collection device 200 may transmit the vehicle status information to the cloud server 300.

[0043] The data collection device 200 can control the components (e.g., software or hardware components) of the data collection device 200 by executing at least one software installed in the data collection device 200, and perform various data processing or operations. The at least one software may include firmware. However, this is only an example, and various embodiments are not limited thereto. For example, the software for controlling the components of the data collection device 200 may include an application.

[0044] The data collection device 200 may store and / or install firmware provided from the cloud server 300. According to an embodiment, the data collection device 200 may determine the type of the vehicle 100 currently connected thereto, transmit vehicle information about the determined type to the cloud server 300, and receive firmware corresponding to the vehicle type information from the cloud server 300 to perform an update operation on the previously installed version firmware. The point in time when the new firmware is applied to the data collection device 200 through the firmware update operation may be the point in time when the data collection device 200 enters the wake-up mode from the sleep mode after entering the sleep mode. Here, the sleep mode may be a mode in which the data collection device 200 performs its minimum function (e.g., a function of receiving a wake-up request to enter a normal mode in which the data collection device 200 performs its main function) without performing its main function (such as, shutting down of the vehicle 100).

[0045] At least one function of the data collection device 200 may be changed by firmware update. The data collection device 200 according to an embodiment of the present disclosure may perform a function change by a simple information change based on communication with the cloud server 300 instead of a firmware update. In this case, the function change may be performed immediately without a process of waking up from a sleep mode.

[0046] The cloud server 300 may receive vehicle status information from the data collection device 200 by transmitting and receiving data to and from the data collection device 200, and provide management services for the vehicle 100 or the battery pack 110 by storing and analyzing the vehicle status information. In addition, the cloud server 300 may provide firmware installed in the data collection device 200 at the request of the data collection device 200.

[0047] Figure 2 It is shown in detail Figure 1 A block diagram of the data collection device is shown.

[0048] Reference Figure 2 , the data collection device 200 may include a main controller 210, a vehicle communication unit 220, a wireless communication unit 230, a function storage unit 240, and a function change unit 250. Each component of the data collection device 200 may be implemented with software, hardware, or a combination thereof.

[0049] The main controller 210 can control the data collection device 200 to perform the reference Figure 1 The main controller 210 may perform a plurality of preset functions of the data collection device 200, and when performing the plurality of functions, refer to the function storage unit 240 to perform the corresponding function according to the application value corresponding to the function stored in the function storage unit 240. For example, the function storage unit 240 may store an application value (e.g., 1 second) corresponding to a monitoring period for obtaining vehicle status information about the status of the vehicle 100 from the internal components of the vehicle 100, and the main controller 210 may perform a monitoring operation to obtain vehicle status information for a period of 1 second according to the application value (e.g., 1 second) corresponding to the monitoring period stored in the function storage unit 240.

[0050] The vehicle communication unit 220 accesses the vehicle network 130 to transmit and receive data to and from internal components (e.g., 110, 120, etc.) of the vehicle 100. The vehicle communication unit 220 may access the vehicle network 130 according to a communication scheme (or standard) determined based on firmware installed in the data collection device 200.

[0051] The wireless communication unit 230 may send and receive data to and from the cloud server 300. The wireless communication unit 230 may establish a wired communication channel between the data collection device 200 and the cloud server 300, and send and receive data to and from the cloud server 300 through the established communication channel. For example, the wireless communication unit 230 may send and receive data to and from another device based on at least one radio access technology (RAT).

[0052] The function storage unit 240 may store an application value corresponding to each of a plurality of preset functions of the data collection device 200. According to an embodiment, the function storage unit 240 may store the application value in the form of a table in which each function and an application corresponding thereto are matched with each other, but the scope of the present disclosure is not limited thereto. In the present disclosure, a table in which functions and application values ​​are matched with each other is defined as a function application table.

[0053] The function storage unit 240 may be referenced by the main controller 210 to provide an application value so that a corresponding function may be executed according to the application value stored in the function storage unit 240. At least one application value of the function storage unit 240 may be stored and / or changed when the data collection device 200 firmware is updated, or may be changed by the operation of the function change unit 250.

[0054] The function change unit 250 may change at least one application value stored in the function storage unit 240. According to an embodiment, the function change unit 250 may change at least one application value stored in the function storage unit 240 by communicating with the cloud server 300. In this case, the function change unit 250 may change the function of the data collection device 200 by changing the corresponding application value of the function application table regardless of the firmware update. Figure 3 and Figure 4 Describes the detailed operations associated with it.

[0055] Figure 3 is a flowchart for describing a function changing method of a data collection device according to an embodiment of the present disclosure. Figure 4 is a diagram showing an example of a function application table stored in a data collection device and a device function table stored in a cloud server.

[0056] Reference Figure 3 and Figure 4 , the data collection device 200 can immediately change the function of the data collection device 200 by operating with the cloud server 300 without the need for firmware updates.

[0057] Reference Figure 4 , the data collection device 200 may store a function application table in which a function item indicating a function executed by the data collection device 200 and an application value item corresponding to the function match each other. The matching function item and application value item may be defined as function application data. That is, the function application table may be a collection of function application data. For example, an application value item of function application data of a mode of a sleep mode (e.g., a sleep mode entry time, a sleep mode period, etc.) may be D2, and the data collection device 200 may operate in the sleep mode in a mode corresponding to D2.

[0058] In addition, the cloud server 300 may store a device function table in which a target item indicating identification information of a data collection device, a function item, a type item indicating a data type, and a setting value / status value item corresponding to the function are matched. Here, the setting value may represent the value of the function of the data collection device 200 set by the cloud server 300, and the status value may represent the value currently set by the function of the data collection device 200. The type item may include a first type SET corresponding to the setting value or a second type STA corresponding to the status value. A value (e.g., D1) matching the first type SET may correspond to the setting value, and a value (e.g., D2) matching the second type STA may correspond to the status value. In addition, there may be multiple data collection devices managed by the cloud server 300, and a target item may be included in the device function table to identify the data collection device corresponding to the setting value or the status value. For example, the identification information of the data collection device 200 may be OBD1, and each of the function setting data and the function status data of the data collection device 200 may have OBD1 in the target item.

[0059] The matched target item, function item, type item and setting value item may be defined as function setting data. The matched target item, function item, type item and status value item may be defined as function status data. That is, the device function table may be a collection of function setting data and function status data.

[0060] The cloud server 300 can operate the function setting data of each data collection device, and set the function setting data corresponding to various conditions (such as specifications) of the data collection device, the characteristics of the driver of the vehicle on which the data collection device is installed (for example, driving habits, battery charging habits, etc.), etc.

[0061] exist Figure 3 In operation S10, the data collection device 200 may send a request for a setting value of a specific function item to the cloud server 300. For example, the data collection device 200 may send a request for a setting value of a monitoring period to the cloud server 300.

[0062] In operation S20, in response to a request for a setting value of a specific function item received from the data collection device 200, the cloud server 300 may send a response including the setting value of the specific function item to the data collection device 200. For example, after receiving a request for a setting value of a monitoring period from the data collection device 200, the cloud server 300 may search for "OBD1" corresponding to the data collection device 200 from the target item, search for "Monitoring Period" corresponding to the monitoring period from the function item, and search for "SET" corresponding to the setting value from the type item by referring to the device function table. The cloud server 300 may determine the setting value D3 of the function setting data 410 (including "OBD1", "MonitoringPeriod", and "SET") as the setting value of the monitoring period corresponding to the data collection device 200, and send a response including D3 to the data collection device 200.

[0063] The data collection device 200 may compare the setting value of the specific function item included in the response of the cloud server 300 with the application value of the specific function item stored in the data collection device 200. For example, the data collection device 200 may compare the setting value of the monitoring period with the application value of the monitoring period stored in the data collection device 200.

[0064] When the setting value of the specific function item is different from the application value of the specific function item (No in operation S30), the data collection device 200 may update the application value of the specific function item to the setting value of the specific function item. For example, when the setting value of the monitoring period is D3 and the application value of the monitoring period is D5 so that they are different from each other (such as Figure 4 As shown), the data collection device 200 may update the application value of the monitoring period of the function application data 420 from D5 to D3.

[0065] When the setting value of the specific function item and the application value of the specific function item are the same (Yes in operation S30), the data collection device 200 may not update the application value of the specific function item. This is because the value set by the cloud server 300 for the specific function item of the data collection device 200 has been applied to the data collection device 200.

[0066] Operations S30 and S40 may represent an operation of reflecting the setting value of a specific function item included in the response of the cloud server 300 to the function application table stored in the data collection device 200. Through these operations, the function change of the data collection device 200 may be performed in real time without firmware update.

[0067] After completing the operation corresponding to the response including the setting value of the specific function item, in operation S50, the data collection device 200 may send a request for the state value of the specific function item to the cloud server 300. The request for the state value of the specific function item may include the application value of the specific function item currently stored in the data collection device 200.

[0068] The cloud server 300 may compare the application value of the specific function item included in the request of the data collection device 200 with the state value of the specific function item stored in the cloud server 300 .

[0069] For example, the cloud server 300 may compare the status value of the monitoring period stored in the cloud server 300 with the application value of the monitoring period. After receiving the application value of the monitoring period from the data collection device 200, the cloud server 300 may search for "OBD1" corresponding to the data collection device 200 from the target item, search for "Monitoring Period" corresponding to the monitoring period from the function item, and search for "STA" corresponding to the status value from the type item by referring to the device function table. The cloud server 300 may compare the status value of the function status data 430 including "OBD1", "Monitoring Period" and "STA" with the application value of the monitoring period received from the data collection device 200.

[0070] When the application value of the specific function item is different from the state value of the specific function item (No in operation S60), in operation S70, the cloud server 300 may update the state value of the specific function item to the application value of the specific function item. For example, when the application value of the monitoring period is D3 and the state value of the monitoring period is D5 so that they are different from each other (such as Figure 4 As shown), the cloud server 300 can update the status value of the monitoring period of the functional status data 430 from D5 to D3.

[0071] When the application value of the specific function item and the status value of the specific function item are the same (Yes in operation S60), the cloud server 300 may not update the status value of the specific function item because the status value of the specific function item already reflects the application value of the specific function item of the data collection device 200.

[0072] Operations S60 and S70 may represent an operation of reflecting the application value of a specific function item included in the request of the data collection device 200 to the function status data of the device function table stored in the cloud server 300. Through these operations, monitoring of the function change result of the data collection device 200 and the currently applied function may be performed.

[0073] In operation S80 , the cloud server 300 may send a response including a status value of a specific function item to the data collection device 200 .

[0074] In the above method, the operation of the data collection device 200 may be mainly performed by the wireless communication unit 230 and the function change unit 250 of the data collection device 200 .

[0075] Reference Figure 3 The described operation may be described as an example of a specific functional item, and various functions of the data collection device 200 may be described in the same manner as in the reference Figure 3 The function change operations are performed sequentially in substantially the same manner as described above. The order of the function change operations for each function (i.e., the function that the function change operation is to be performed first) and / or the time period (how frequently the function change operation is to be performed on the corresponding function) can be predetermined and stored in the data collection device 200.

[0076] Using the function changing method of a data collection device according to an embodiment of the present disclosure, in order to change the specific function of the data collection device 200, the cloud server 300 can change the specific function of the data collection device 200 by changing the setting value corresponding to the specific function of the data collection device 200 in the device function table without a firmware update.

[0077] When the function of the data collection device 200 is changed by firmware update, the same firmware is applied to the same model, so that for each data collection device, function change is impossible according to various conditions such as the characteristics of the driver. However, using the function change method of the data collection device according to the embodiment of the present disclosure, the cloud server 300 can independently change the specific function of the data collection device for each data collection device according to various conditions such as the characteristics of the driver.

[0078] The cloud server 300 can analyze the vehicle status information received from the data collection device 200 to determine whether a function change of the data collection device 200 is required, and when a specific function needs to be changed, change the setting value corresponding to the specific function of the data collection device 200 in the device function table, and when executing Figure 3 When operating as shown, the functionality of the data collection device 200 is changed in real time.
