DETAILED DESCRIPTION OF THE INVENTION

[0030] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that when referring to components in each drawing, the same components are referred to by the same reference numerals whenever possible, even when they appear in other drawings. Furthermore, when describing the embodiments of the present invention, if a detailed description of related known structures or functions is deemed to hinder understanding of the embodiments of the present invention, the detailed description will be omitted.

[0031] When describing components of an embodiment of the present invention, terms such as "first," "second," "A," "B," "(a)," and "(b)" may be used. These terms are merely used to distinguish the component from other components and do not limit the essence, order, or procedure of the components. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention pertains. Terms defined in commonly used dictionaries should be interpreted as having a meaning consistent with the context of the relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly defined in this document.

[0032] In the following description, the term "vehicle" may refer to both a vehicle operated by a driver and an autonomous vehicle capable of operating independently without a driver. Although the following description will be given using an automobile as an example of a vehicle, the present invention is not limited thereto. For example, the following various embodiments may also be applied to various means of transportation, such as a ship, an airplane, a train, a motorcycle, or a bicycle.

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

[0034] Referring to FIG. 1 a, an electric power consumption analysis system 100 according to various embodiments may include a vehicle diagnostic device 110 and an electric power consumption analysis device 120 . According to various embodiments, the vehicle diagnostic device 110 is provided inside the vehicle 10 and can acquire information related to the state of the vehicle 10 or the driving of the vehicle 10. The information related to the state of the vehicle 10 can include diagnostic information related to components of the vehicle 10 (e.g., a battery, sensors, a motor, an acceleration system, a deceleration system, etc.). Furthermore, the information related to the driving of the vehicle 10 can include speed information, mileage information, driving time information, driving position information, fuel consumption information, etc. of the vehicle 10. According to one embodiment, the vehicle diagnostic device 110 can include an On-Board Diagnostic (OBD) device. Such an OBD device can include not only OBD-I, OBD 1.5, and OBD-II, but also various devices that output information related to the state or driving of the vehicle 10 to an external device (e.g., an electric power consumption analysis device 120).

[0035] According to various embodiments, the electricity consumption analysis device 120 may analyze factors affecting the electricity consumption of the vehicle 10 based on various information acquired via the vehicle diagnosis device 110. The electricity consumption analysis device 120 may calculate a standard electricity consumption contribution rate indicating the degree to which the vehicle 10's travel section (or the section where the vehicle 10's electrical energy is consumed) has affected the profit or loss (e.g., increase or decrease) of the vehicle 10's current electricity consumption relative to the vehicle's standard electricity consumption (e.g., certified electricity efficiency), and output the calculation result. The standard electricity consumption rate is an electricity consumption rate measured under specified measurement conditions and may be measured by the vehicle diagnosis device 110 or the electricity consumption analysis device 120, or may be measured by a designated certification body. For example, the electricity consumption analysis device 120 may include a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a wearable device, or a server (e.g., a cloud server), and various embodiments are not limited thereto. The calculation of the standard electricity cost contribution rate by 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. Fig. 2a and Fig. 2b are diagrams for explaining the calculation operation of the standard electricity cost contribution according to various embodiments. Fig. 3a and Fig. 3b are diagrams for explaining the calculated value of the standard electricity cost contribution according to various embodiments. Fig. 4a to Fig. 4c are diagrams for explaining the output operation of the standard electricity cost contribution according to various embodiments.

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

[0038] According to various embodiments, the communication circuitry 122 can establish a wired or wireless communication channel between the electric consumption analysis device 120 and the vehicle diagnostic device 110 and support communication over the established communication channel. The communication circuitry 122 can also communicate with other external devices (e.g., servers) in addition to the vehicle diagnostic device 110.

[0039] For example, communication circuitry 122 may include wireless communication circuitry (eg, cellular communication circuitry or short-range wireless communication circuitry), or wired communication circuitry (eg, local area network (LAN) communication circuitry or power line communication circuitry).

[0040] According to various embodiments, memory 124 may include programs, algorithms, routines, and / or instructions related to the operation (or control) of electricity consumption analyzer 120 .

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

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

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

[0044] According to various embodiments, the processor 128 may control at least one other component of the power consumption analysis device 120 (e.g., the communications circuitry 122, the memory 124, and the output device 126) and may perform various data processing or calculations.

[0045] According to one embodiment, the processor 128 can provide an electric fuel economy (or electric driving economy) for the vehicle 10 based on various information obtained via the vehicle diagnostic device 110. The electric fuel economy can be calculated as the distance that can be driven per kWh of electric energy.

[0046] For example, the processor 128 may obtain information regarding the distance traveled over a certain distance and the amount of electric energy consumed via the vehicle diagnostic device 110. In this regard, the processor 128 may calculate the electric efficiency using the ratio of the amount of electric energy consumed to the distance traveled.

[0047] Providing such electricity cost information helps drivers plan charging while or before driving. However, electricity cost can vary depending on road conditions, the driver's driving habits, and the vehicle's condition, even for the same type of vehicle, and electricity cost information does not allow drivers to recognize factors that influenced the formation of electricity cost.

[0048] In this regard, as will be described later, the processor 128 can analyze factors that have affected the electric fuel economy of the vehicle 10 based on various information acquired via the vehicle diagnostic device 110. For example, the processor 128 can calculate a standard electric fuel economy contribution rate that indicates the degree to which the factors have affected the profit or loss (e.g., increase or decrease) of the current electric fuel economy of the vehicle 10 relative to the standard electric fuel economy (e.g., certified electric fuel economy) of the vehicle 10.

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

[0050] According to one embodiment, the processor 128 may divide a monitoring section, in which the consumption of electric energy is monitored as the vehicle 10 travels, into a plurality of sections and calculate the standard electric energy cost contribution for each of the divided sections. In this case, the processor 128 may divide the monitoring section into a plurality of speed sections.

[0051] For example, as shown in FIG. 2a, the processor 128 can divide the monitoring section 200 into a first section (e.g., a high-speed section) 210 corresponding to a first speed range (e.g., 81 km / h or higher), a second section (e.g., a 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., a 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, processor 128 may calculate a first standard electricity cost contribution, a second standard electricity cost contribution, and a third standard electricity cost contribution for first section 210, second section 220, and third section 230, respectively. According to one embodiment, the processor 128 may use the following Equation 1 to calculate the standard electricity cost contribution.

[0059] According to one embodiment, an example of the standard electricity cost contribution calculated based on the above Equation 1 can be summarized as shown in Table 1 below.

[0060] [Table 1]

[0061] Referring to Table 1 above, the sum of the standard electricity consumption rate and the standard electricity consumption rate contribution rate of each section (e.g., 3 - (0.3) + (0.3) - (0.4) = 2.6) is the same as the electricity consumption rate for all sections (e.g., Sections 1 to 3) (e.g., 26 km / 10 kWh = 2.6). It can also be seen that the electricity consumption rate of Section 1 (e.g., 2 km / kWh) and the electricity consumption rate of Section 3 (e.g., 2 km / kWh) are the same, but the standard electricity consumption rate of Section 1 (e.g., -0.3) and the standard electricity consumption rate of Section 3 (e.g., -0.4) are different. This means that the standard electricity consumption rate contribution rate for the same electricity consumption rate section may differ depending on the driver's driving behavior. In this regard, processor 128 can accurately analyze the factors that affected the electricity consumption rate based on the standard electricity consumption rate contribution rate and provide the result to the driver. As described above, the electricity consumption analysis device 120 may calculate the electricity consumption rate and the electricity consumption profit / loss value based on various information acquired via the vehicle diagnosis device 110. However, this is merely an example, and various embodiments are not limited thereto. For example, at least a portion of the electricity consumption rate and the electricity consumption profit / loss value may be calculated by the vehicle diagnosis device 110 or another external device and provided to the electricity consumption analysis device 120. According to one embodiment, when calculating the standard electricity consumption contribution, the processor 128 may divide the monitoring section into a plurality of speed sections and then divide each speed section into a plurality of sections. In this case, the processor 128 may divide each speed section into a plurality of speed change sections. The speed change section may include at least one of an acceleration section (e.g., a section including acceleration of less than 10 km / h per second), a rapid acceleration section (e.g., a section including acceleration of 10 km / h or more per second), a deceleration section (e.g., a section including deceleration of less than 10 km / h per second), a rapid deceleration section (e.g., a section including deceleration of 10 km / h or more per second), or a constant speed section (e.g., a section where the section average acceleration is less than 0.2).

[0062] 2b, the processor 128 may divide the first section 210 of the monitoring section 200 into speed change sections, such as a constant speed section 212, a sudden acceleration section 214, and a sudden deceleration section 216, and may 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. Alternatively, the processor 128 may divide only some of the sections of the first section 210 of the monitoring section 200, among the constant speed section 212, the sudden acceleration section 214, and the sudden deceleration section 216, that satisfy a specified condition, as speed change sections. Of course, the processor 128 may also divide only some of the speed sections of the monitoring section 200 that satisfy a specified condition as speed change sections. The processor 128 can then calculate the standard electricity cost contribution for each speed interval.

[0063] As described above, the standard electricity cost contribution may be calculated based on a section (e.g., a monitoring section) in which electric energy is consumed by traveling the vehicle 10. However, this is merely an example, and various embodiments are not limited thereto. For example, additionally or alternatively, the processor 128 may further calculate the standard electricity cost contribution based on a section in which energy is consumed in a state in which substantially no traveling is occurring (e.g., a stopped state).

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

[0065] According to one embodiment, as shown in Fig. 4a, processor 128 can output (400) electricity cost contribution information including first electricity cost contribution information 410 relating to recent electricity cost (or recent driving) and second electricity cost contribution information 420 relating to electricity cost history (or past driving history). In this case, processor 128 can receive user input and selectively output first electricity cost contribution information 410 or second electricity cost contribution information 420. Of course, processor 128 can output both first electricity cost contribution information 410 and second electricity cost contribution information 420, regardless of whether it receives user input or not.

[0066] According to one embodiment, the first electricity consumption contribution information 410 may include an average electricity consumption from a recent trip (e.g., a recent average electricity consumption: 7.4 km / kWh) 411, and a standard electricity consumption contribution 412 for each speed section monitored in the recent trip. Additionally, the first electricity consumption contribution information 410 may include a graph 414 of the standard electricity consumption contribution for each monitored speed section. This allows the driver to recognize speed sections that improve or reduce electricity consumption, and as a result, the driver's driving habits may be regulated to improve electricity consumption.

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

[0068] For example, when one speed section (e.g., a low-speed section) is selected using the standard electricity consumption contribution 412 for each speed section or the standard contribution electricity consumption graph 414, the processor 128 can provide a standard electricity consumption contribution 416 for each speed change section (e.g., a rapid acceleration section, an acceleration section, a slow acceleration section, a rapid deceleration section, a deceleration section, a slow deceleration section, or a constant speed section) for the selected speed section, as shown in Fig. 4b. This allows the driver to recognize actions that relatively reduce electricity consumption in the low-speed section (e.g., acceleration actions) and actions that relatively improve electricity consumption (e.g., deceleration actions).

[0069] According to one embodiment, when processor 128 outputs the electricity cost contribution information, it may also provide information on the bottom line cost incurred due to the standard electricity cost contribution. In this regard, processor 128 may calculate the bottom line cost by multiplying the standard electricity cost contribution by the unit energy cost (e.g., cost per kWh). Furthermore, when processor 128 outputs the electricity cost contribution information, it may provide information on the proportion of sections with at least a high standard electricity cost contribution or sections with a low standard electricity cost among all driving sections.

[0070] According to one embodiment, processor 128 may provide a comparison result between the standard electricity consumption contribution of past driving and the standard electricity consumption contribution of the current driving based on second electricity consumption contribution information 420 related to the electricity consumption history. In this case, processor 128 may select a predetermined one of the standard electricity consumption contributions of multiple stored past drivings and compare it with the standard electricity consumption contribution of the current driving. For example, at least one of a past driving with optimal electricity consumption, a driving performed immediately before the current driving, a past driving performed on a route similar to the current driving, or multiple past driving performed within a certain period of time may be determined as the comparison target to be compared with the current driving.

[0071] For example, as shown in FIG. 4c, processor 128 may output second electricity cost contribution information 420 including a graph 422 comparing the decrease or increase in electricity cost for the current trip compared to past trips, and text information 424 regarding the comparison results.

[0072] Additionally or alternatively, second electricity consumption contribution information 420 may include an object (e.g., a detailed information confirmation icon) 426 that outputs detailed information about a decrease or increase in electricity consumption during the current trip compared to past trips. Thus, when a user input to the object is detected, processor 128 may provide detailed information 428 about a section where electricity consumption during the current trip decreased or increased compared to past trips, or about a speed change section (or action) that decreased or increased electricity consumption compared to that section, as shown in Fig. 4d. In Fig. 4d, a radar chart is used to provide detailed information 428 that compares electricity consumption during the past trip with electricity consumption during the current trip, but various embodiments are not limited to this.

[0073] Hereinafter, with reference to FIGS. 5 and 6, the operation methods of the electricity consumption analysis device 120 according to various embodiments will be specifically described. FIG. 5 is a flowchart illustrating the operation of an electricity consumption analysis device according to various embodiments. The operations in the following embodiments may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, or at least two operations may be performed in parallel. Furthermore, at least one of the following operations may be omitted depending on the embodiment.

[0074] Referring to FIG. 5, the electricity consumption analysis device 120 (e.g., processor 128) may monitor the energy consumption of the vehicle at operation 510. According to one embodiment, the electricity consumption analysis device 120 may monitor the energy consumption of the vehicle based on information acquired via the vehicle diagnostic device 110. For example, the electricity consumption analysis device 120 may perform monitoring during a section where electric energy is consumed due to driving (e.g., a driving section). As another example, the electricity consumption analysis device 120 may also perform monitoring when substantially no driving is occurring (e.g., a stopped section).

[0075] According to various embodiments, the electricity consumption analysis device 120 (e.g., processor 128) can divide (or segment) the monitoring section into multiple sections in operation 520. According to one embodiment, the electricity consumption analysis device 120 can divide the monitoring section into multiple speed sections.

[0080] According to another embodiment, the electricity cost analysis device 120 may also provide information on the profit and loss costs generated by the standard electricity cost contribution. In this regard, the electricity cost analysis device 120 may calculate the profit and loss costs by multiplying the standard electricity cost contribution by the unit energy cost (e.g., cost per kWh).

[0081] In another embodiment, the electricity consumption analysis device 120 may provide information on the proportion of sections with a high standard electricity consumption contribution or sections with a low standard electricity consumption, among all sections of the trip.
