[0030] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. When assigning reference numerals to the components of each drawing, it should be noted that the same components are assigned the same numerals as much as possible when they are shown on other drawings. Further, when explaining the embodiments of the present invention, if it is determined that a specific explanation of a related known configuration or function hinders the understanding of the embodiments of the present invention, the detailed explanation thereof will be omitted.

[0031] When explaining the components of the embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are merely for distinguishing the components from other components, and the essence, order, or procedure of the components are not limited by such terms. Also, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. Terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the related art, and should not be interpreted in an ideal or overly formal sense unless clearly defined in this document.

[0032] The vehicle mentioned in the following description may also mean a vehicle that is operated by the driver's boarding and operation, and an autonomous vehicle that has a function of operating by itself without the driver's operation. Also, in the following description, an automobile is described as an example of a vehicle, but the present invention is not limited thereto. For example, the following various embodiments can also be applied to various means of transportation such as ships, airplanes, trains, motorcycles, or bicycles.

[0033] Hereinafter, embodiments of the present invention will be specifically described with reference to FIGS. 1a to 6. FIG. 1a is a diagram schematically showing the configuration of an electricity cost analysis system according to various embodiments.

[0034] Referring to FIG. 1a, the electricity cost analysis system 100 according to various embodiments can be composed of a vehicle diagnostic device 110 and an electricity cost analysis device 120. According to various embodiments, the vehicle diagnostic device 110 is provided inside the vehicle 10 and can acquire information regarding the state of the vehicle 10 or the driving of the vehicle 10. The information regarding the state of the vehicle 10 can include diagnostic information regarding components of the vehicle 10 (for example, a battery, a sensor, a motor, an acceleration device, a deceleration device, etc.). Also, the information regarding the driving of the vehicle 10 can include speed information of the vehicle 10, travel distance information, travel time information, travel position information, fuel consumption information, etc. According to one embodiment, the vehicle diagnostic device 110 can include an OBD (On-Board Diagnostic) device. Such an OBD device may include not only OBD-I, OBD 1.5, and OBD-II, but also various devices that output information regarding the state or driving of the vehicle 10 to the outside (for example, the electricity cost analysis device 120).

[0035] According to various embodiments, the electricity cost analysis device 120 can analyze factors that have affected the electricity cost of the vehicle 10 based on various information acquired via the vehicle diagnostic device 110. The electricity cost analysis device 120 can calculate a standard electricity cost contribution degree indicating the extent to which the driving section of the vehicle 10 (or the section where the electrical energy of the vehicle 10 is consumed) has affected the profit and loss (for example, increase or decrease) of the current electricity cost of the vehicle 10 with respect to the standard electricity cost of the vehicle 10 (for example, certified electricity efficiency), and output the calculation result. The above-mentioned standard electricity cost is the electricity cost measured under a situation satisfying specified measurement conditions, and may be measured by the vehicle diagnostic device 110 or the electricity cost analysis device 120, or measured by a specified certification institution. For example, the electricity cost analysis device 120 can include a portable communication device (for example, a smartphone), a computer device, a portable multimedia device, a wearable device, or a server (for example, a cloud server), and various embodiments are not limited thereto. The calculation of the standard electricity cost contribution of the electricity cost analysis device 120 according to various embodiments will be described in detail with reference to the following drawings.

[0036] FIG. 1b is a diagram showing the configuration of an electricity cost analysis device according to various embodiments. FIGS. 2a and 2b are diagrams for explaining the calculation operation of the standard electricity cost contribution according to various embodiments, FIGS. 3a and 3b are diagrams for explaining the calculated values of the standard electricity cost contribution according to various embodiments, and FIGS. 4a to 4c are diagrams for explaining the output operation of the standard electricity cost contribution according to various embodiments.

[0037] Referring to FIG. 1b, the electricity cost analysis device 120 can include a communication circuit 122, a memory 124, an output device 126, and a processor 128. However, this is exemplary, and various embodiments are not limited thereto. For example, at least one of the components of the electricity cost analysis device 120 described above may be omitted, or one or more other components (for example, an input device, at least one sensor, a power management device, etc.) may be added as the configuration of the electricity cost analysis device 120. Also, at least one of the components described above may be integrated with other components.

[0038] According to various embodiments, the communication circuit 122 can establish a wired or wireless communication channel between the electricity cost analysis device 120 and the vehicle diagnostic device 110 and support the execution of communication via the established communication channel. Also, the communication circuit 122 may form a communication with other external devices (for example, a server) in addition to the vehicle diagnostic device 110.

[0039] For example, the communication circuit 122 can include a wireless communication circuit (for example, a cellular communication circuit or a short-range wireless communication circuit), or a wired communication circuit (for example, a LAN (local area network) communication circuit or a power line communication circuit).

[0040] According to various embodiments, the memory 124 can include programs, algorithms, routines, and / or instruction words related to the operation (or control) of the electricity cost analysis device 120.

[0041] For example, the memory 124 can include a memory such as a flash memory type, a hard disk type, a micro type, and a card type (e.g., Secure Digital Card (SD card) or eXtream Digital Card (XD card)), and at least one type of storage medium of memories of the RAM (Random Access Memory), SRAM (Static RAM), ROM (Read-Only Memory), PROM (Programmable ROM), EEPROM (Electrically Erasable PROM), magnetic memory (MRAM, Magnetic RAM), magnetic disk, and optical disk types. Various embodiments are not limited thereto.

[0042] According to various embodiments, the output device 126 can provide information related to the operation of the electricity cost analysis device 120. According to one embodiment, the output device 126 can include a display configured to output visual information. For example, the display can include any one or more of a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a 3D display, and a transparent display. Further, the display may include a touch sensor set to detect touch.

[0043] However, this is exemplary and various embodiments are not limited thereto. For example, information regarding the operation of the electricity cost analysis device 120 may be provided as auditory information. In this case, the output device 126 can further include an acoustic output device (e.g., a speaker) configured to output an acoustic signal outside the electricity cost analysis device 120.

[0044] According to various embodiments, the processor 128 can control at least one other component of the electricity cost analysis device 120 (e.g., the communication circuit 122, the memory 124, and the output device 126), and can perform various data processing or operations.

[0045] According to one embodiment, the processor 128 can provide the electricity cost (or the running electricity cost) for the vehicle 10 based on various information acquired via the vehicle diagnostic device 110. The electricity cost can be calculated as the travelable distance per 1 kwh of electrical energy.

[0046] For example, the processor 128 can acquire information regarding the travel distance and the electrical energy consumption amount in a certain section via the vehicle diagnostic device 110. In relation to this, the processor 128 can calculate the electricity cost using the ratio of the electrical energy consumption amount to the travel distance.

[0047] The provision of such electricity cost is helpful for the driver to make a charging plan during or before driving. However, the electricity cost can vary depending on factors such as road conditions, the driver's driving habits, and the vehicle's state even for the same type of vehicle, and the driver cannot recognize the factors that affected the formation of the electricity cost from the electricity cost.

[0048] In connection with this, as will be described later, the processor 128 can analyze the factors that have affected the electricity cost of the vehicle 10 based on various information obtained via the vehicle diagnostic device 110. For example, the processor 128 can calculate a standard electricity cost contribution degree indicating the extent to which the current electricity cost of the vehicle 10 (e.g., increase or decrease) has affected the profit and loss of the standard electricity cost (e.g., recognized electricity cost) of the vehicle 10.

[0049] According to one embodiment, the processor 128 can divide (or split) the section in which the electrical energy of the vehicle 10 is consumed into a plurality of sections, and calculate the standard electricity cost contribution degree for each of the divided sections.

[0050] According to one embodiment, the processor 128 can divide the monitoring section in which the consumption of electrical energy is monitored due to the running of the vehicle 10 into a plurality of sections, and calculate the standard electricity cost contribution degree for each of the divided sections. At this time, the processor 128 can divide the monitoring section into a plurality of speed sections.

[0051] For example, as shown in FIG. 2a, the processor 128 divides the monitoring section 200 into a first section (e.g., high-speed section) 210 corresponding to a first speed range (e.g., 81 km / h or more), a second section (e.g., medium-speed section) 220 corresponding to a second speed range (e.g., 31 km / h to 80 km / h), and a third section (e.g., low-speed section) 230 corresponding to a third speed range (e.g., 1 km / h to 30 km / h) based on the speed of the vehicle 10.

[0052] Thereafter, the processor 128 can calculate a first standard electricity cost contribution degree, a second standard electricity cost contribution degree, and a third standard electricity cost contribution degree for the first section 210, the second section 220, and the third section 230, respectively. According to one embodiment, the processor 128 can use the following <Equation 1> when calculating the standard electricity cost contribution degree.

[0059] According to one embodiment, examples of the standard electricity cost contribution degree calculated based on the above <Equation 1> can be summarized as shown in the following .

[0060]

Table 1

[0061] Referring to the above , the sum of the standard electricity charge and the standard electricity charge contribution degree of each section (for example, 3 - (0.3) + (0.3) - (0.4) = 2.6) is the same as the electricity charge for all sections (for example, the first section to the third section) (for example, 26 km / 10 kwh = 2.6). Also, the electricity charge for the first section (for example, 2 km / kwh) and the electricity charge for the third section (for example, 2 km / kwh) are the same as each other, but it can be seen that the standard electricity charge contribution degree for the first section (for example, -0.3) and the standard electricity charge contribution degree for the third section (for example, -0.4) are different from each other. This means that depending on the driver's driving behavior, the standard electricity charge contribution degree in the same electricity charge section can be different. In connection with this, the processor 128 can accurately analyze the factors that affected the electricity charge based on the standard electricity charge contribution degree and provide it to the driver. As described above, the electricity charge analysis device 120 can calculate the power consumption rate and the electricity charge profit and loss value based on various information obtained through the vehicle diagnostic device 110. However, this is exemplary, and various embodiments are not limited to this. For example, at least a part of the power consumption rate and the electricity charge profit and loss value may be calculated by the vehicle diagnostic device 110 or other external devices and provided to the electricity charge analysis device 120. According to one embodiment, when calculating the standard electricity charge contribution degree, the processor 128 can divide the monitoring section into a plurality of speed sections, and each speed section can be divided into a plurality of sections again. At this time, the processor 128 can divide each speed section into a plurality of speed change sections. The speed change section can include at least one of an acceleration section (for example, a section including an acceleration of less than 10 km / h per second), a rapid acceleration section (for example, a section including an acceleration of 10 km / h or more per second), a deceleration section (for example, a section including a deceleration of less than 10 km / h per second), a rapid deceleration section (for example, a section including a deceleration of 10 km / h or more per second), or a constant speed section (for example, a section where the average acceleration of the section is less than 0.2).

[0062] For example, as shown in FIG. 2b, the processor 128 divides the first section 210 of the monitoring section 200 into speed change sections such as a constant speed section 212, a rapid acceleration section 214, and a rapid deceleration section 216, and can also divide the second section 220 of the monitoring section 200 into speed change sections such as an acceleration section 222 and a deceleration section 224. Further, the processor 128 may divide only some of the sections that satisfy the specified conditions among the constant speed section 212, the rapid acceleration section 214, and the rapid deceleration section 216 for the first section 210 of the monitoring section 200 into speed change sections. Of course, the processor 128 may divide only some of the sections that satisfy the specified conditions among the plurality of speed sections of the monitoring section 200 into speed change sections. Thereafter, the processor 128 can calculate the standard electricity cost contribution degree for each speed section.

[0063] As described above, the standard electricity cost contribution degree can be calculated based on the section (for example, the monitoring section) in which electrical energy is consumed due to the running of the vehicle 10. However, this is exemplary, and various embodiments are not limited thereto. For example, additionally or alternatively, the processor 128 may further calculate the standard electricity cost contribution degree based on the section in which energy is consumed in a state where substantially no running is performed (for example, a stopped state).

[0064] According to one embodiment, the processor 128 can calculate the power consumption rate based on the power consumed in the stopped state. For example, the processor 128 may calculate the standard electricity cost contribution degree for the stopped state based on the power consumption rate calculated based on the power consumed by an air conditioner (for example, a cooling device, a heating device, etc.) and the electricity cost profit and loss value calculated in the stopped state (for example, the driving distance is 0 km). According to various embodiments, the processor 128 can output information regarding the calculated standard electricity cost contribution degree (or electricity cost contribution degree information).

[0065] According to one embodiment, as shown in FIG. 4a, the processor 128 can output (400) electricity cost contribution information including first electricity cost contribution information 410 regarding the recent electricity cost (or recent driving) and second electricity cost contribution information 420 regarding the electricity cost history (or past driving history). At this time, the processor 128 can receive user input and selectively output the first electricity cost contribution information 410 or the second electricity cost contribution information 420. Of course, the processor 128 may receive user input or output both the first electricity cost contribution information 410 and the second electricity cost contribution information 420 regardless of the user input.

[0066] According to one embodiment, the first electricity cost contribution information 410 can include the average electricity cost due to recent driving (for example, recent average electricity cost: 7.4 km / kwh) 411 and the standard electricity cost contribution 412 for each speed range monitored during recent driving. Additionally, the first electricity cost contribution information 410 may include a graph 414 of the standard contribution electricity cost for each monitored speed range. Thereby, the driver can recognize the speed ranges for improving or reducing the electricity cost, and as a result, can also induce the driver's driving habits for improving the electricity cost.

[0067] Additionally or alternatively, while the first electricity cost contribution information 410 is being output, the processor 128 may provide details of the standard electricity cost contribution for at least one of the speed ranges based on user input.

[0068] For example, when any one of the speed ranges (for example, a low-speed range) is selected by the standard electricity cost contribution 412 or the graph 414 of the standard contribution electricity cost for each speed range, as shown in FIG. 4b, the processor 128 can provide the standard electricity cost contribution 416 for the selected speed range according to the speed change range (for example, a rapid acceleration range, an acceleration range, a gentle acceleration range, a rapid deceleration range, a deceleration range, a gentle deceleration range, or a constant speed range). Thereby, the driver can recognize the actions (for example, an acceleration action) for relatively reducing the electricity cost and the actions (for example, a deceleration action) for relatively improving the electricity cost in the low-speed range.

[0069] According to one embodiment, when outputting the electricity cost contribution degree information, the processor 128 may also provide information regarding the profit and loss cost generated by the standard electricity cost contribution degree. In this connection, the processor 128 can calculate the profit and loss cost by multiplying the standard electricity cost contribution degree by the unit energy cost (for example, the cost per kwh). Further, when outputting the electricity cost contribution degree information, the processor 128 may provide information regarding the ratio occupied by at least the section with a high standard electricity cost contribution degree or the section with a low standard electricity cost section in the entire driving section.

[0070] According to one embodiment, the processor 128 may provide a comparison result between the standard electricity cost contribution degree due to past driving and the standard electricity cost contribution degree due to current driving based on the second electricity cost contribution degree information 420 regarding the electricity cost history. At this time, the processor 128 can select any one of the stored standard electricity cost contribution degrees due to a plurality of past drives and compare it with the standard electricity cost contribution degree due to current driving. For example, it is possible to determine a comparison target for comparing at least one of the past drives in which optimal electricity cost driving was performed, the drive performed immediately before the current drive, the past drives performed on a route similar to the current drive, and the plurality of past drives performed during a certain period with the current drive.

[0071] For example, as shown in FIG. 4c, the processor 128 can output the second electricity cost contribution degree information 420 including a graph 422 comparing the electricity cost decreased or increased in the current drive with respect to the past drive and text information 424 regarding the comparison result.

[0072] Additionally or alternatively, the second electricity cost contribution degree information 420 can include an object (e.g., a detailed information confirmation icon) 426 that outputs detailed information on whether the current driving has decreased or increased the electricity cost compared to past driving. Thus, when a user input to the object is detected, the processor 128 may provide, as shown in FIG. 4d, detailed information on the section where the electricity cost has decreased or increased in the current driving compared to past driving, or detailed information 428 on the speed change section (or behavior) that has decreased or increased the electricity cost for that section. In FIG. 4d, the comparison result between the electricity cost of past driving and the electricity cost of current driving is provided as detailed information 428 by a radar chart, but various embodiments are not limited to this.

[0073] Hereinafter, with reference to FIGS. 5 and 6, a method of operating the electricity cost analysis device 120 according to various embodiments will be specifically described. FIG. 5 is a flowchart for explaining the operation of the electricity cost analysis device according to various embodiments. Each operation in the following embodiments may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, or at least two operations may be performed in parallel. Also, at least one of the following operations may be omitted depending on the embodiment.

[0074] Referring to FIG. 5, the electricity cost analysis device 120 (e.g., the processor 128) can monitor the vehicle's energy consumption in operation 510. According to one embodiment, the electricity cost analysis device 120 can monitor the vehicle's energy consumption based on information obtained via the vehicle diagnostic device 110. For example, the electricity cost analysis device 120 can perform monitoring during a section where electrical energy is consumed by driving (e.g., a driving section). As another example, the electricity cost analysis device 120 may perform monitoring even in a state where substantially no driving is being performed (e.g., a parking section).

[0075] According to various embodiments, the electricity cost analysis device 120 (e.g., the processor 128) can divide (or split) the monitoring period into a plurality of periods in operation 520. According to one embodiment, the electricity cost analysis device 120 can divide the monitoring period into a plurality of speed periods. The plurality of speed periods can include a first period (e.g., a high-speed period) corresponding to a first speed range (e.g., 81 km / h or more), a second period (e.g., a medium-speed period) corresponding to a second speed range (e.g., 31 km / h to 80 km / h), and a third period (e.g., a low-speed period) corresponding to a third speed range (e.g., 1 km / h to 30 km / h).

[0076] According to various embodiments, the electricity cost analysis device 120 (e.g., the processor 128) can calculate the power consumption rate and the electricity cost profit and loss value for each period in operation 530.

[0080] According to other embodiments, the electricity cost analyzer 120 may also provide information regarding the profit and loss costs generated by the standard electricity cost contribution. In this regard, the electricity cost analyzer 120 can calculate the profit and loss costs by multiplying the standard electricity cost contribution by the unit energy cost (e.g., the cost per kwh).

[0081] According to still other embodiments, the electricity cost analyzer 120 may provide information regarding the proportion occupied by at least a section with a high standard electricity cost contribution or a section with a low standard electricity cost section in the entire driving section.
