Background Art

[0005] Due to increasing concerns about the environment, adoption of environmentally friendly vehicles such as electric vehicles and fuel cell vehicles has increased. These environmentally friendly vehicles are equipped with batteries and run on the power of the batteries.

[0006] The vehicle provides a function of calculating the electrical efficiency (or driving electrical efficiency) of the vehicle and displaying it through a meter such as a dashboard. The electrical efficiency can be calculated as the distance that can be traveled per 1 kWh (kilowatt) of electrical energy.

[0046] The vehicle referred to in the following description may include a vehicle operated under the control of a riding driver and an autonomous vehicle that can operate on its own without driver manipulation. In addition, the following description describes a car as an example of a vehicle, but the present invention is not limited thereto. For example, the following embodiments may be applied to various vehicles, such as a ship, an aircraft, a train, a motorcycle, or a bicycle.

[0047] In the following, reference is made to Figures 1a to 6 Embodiments of the present invention are described in detail.

[0048] Figure 1a is a schematic diagram illustrating a configuration of an electric efficiency analysis system according to various embodiments.

[0049] Reference Figure 1a , the electric efficiency analysis system 100 according to various embodiments may include a vehicle diagnosis device 110 and an electric efficiency analysis device 120 .

[0050] According to various embodiments, the vehicle diagnostic device 110 can be installed in the vehicle 10 and can obtain information related to the state or operation of the vehicle 10. The information related to the state of the vehicle 10 may include information about the components of the vehicle 10 (e.g., batteries, sensors, motors, accelerators, and retarder). In addition, the information related to the operation of the vehicle may include the speed, travel distance, driving time, location, and power consumption of the vehicle 10. In an embodiment, the vehicle diagnostic device 110 may include an on-board diagnostic (OBD) device. Such an OBD device may cover various devices (e.g., a fuel efficiency analysis device 120) that output information about the vehicle condition or driving to the outside, not limited to OBD-I, OBD 1.5, and OBD-II.

[0051] According to various embodiments, the electric efficiency analysis device 120 can analyze factors affecting the electric efficiency of the vehicle based on various information obtained through the vehicle diagnostic device 110. The electric efficiency analysis device 120 can calculate the standard electric efficiency contribution, which represents the degree of influence of the current electric efficiency of the vehicle 10 on the gain or loss (e.g., increase or decrease) within the driving interval (or the interval in which the electric energy of the vehicle 10 is consumed) compared with the standard electric efficiency (e.g., certified electric efficiency). The standard electric efficiency can be measured under specific conditions by the vehicle diagnostic device 110, the electric efficiency analysis device 120, or a designated certification agency. For example, the electric efficiency analysis device 120 may include a portable communication device such as a smart phone, a computer device, a portable multimedia device, a wearable device, or a server such as a cloud server, and the various embodiments are not limited to the examples.

[0052] Hereinafter, calculation of the standard electric efficiency contribution by the electric efficiency analysis device 120 will be described in detail with reference to the accompanying drawings.

[0053] Figure 1b is a diagram illustrating a configuration of an electric efficiency analysis device according to various embodiments. Figure 2a and Figure 2b is a diagram illustrating a calculation operation of a standard electric efficiency contribution according to various embodiments, Figure 3a and Figure 3b is a diagram illustrating the calculated values ​​of the standard electrical efficiency contribution according to each embodiment, and finally, Figures 4a to 4d 2 is a diagram illustrating an output operation of a standard electric efficiency contribution according to various embodiments.

[0054] Reference Figure 1b, the electric efficiency analysis device 120 may 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 component of the electric efficiency analysis device 120 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 electric efficiency analysis device 120. In addition, at least one of the components may be integrated with other components.

[0055] According to various embodiments, the communication circuit 122 can establish a wired or wireless communication channel between the electric efficiency analysis device 120 and the vehicle diagnostic device 110, and support communication operations through the established communication channel. In addition, the communication circuit 122 can also establish communication with other external devices (e.g., a server) other than the vehicle diagnostic device 110.

[0056] For example, the communication circuit 122 may include a wireless communication circuit (eg, a cellular communication circuit or a short-range wireless communication circuit) or a wired communication circuit (eg, a local area network or a power line communication circuit).

[0057] According to various embodiments, the memory 124 may contain programs, algorithms, routines, and / or instructions related to the operation (or control) of the electrical efficiency analysis device 120 .

[0058] For example, the memory 124 may include memory types such as a flash memory type, a hard disk type, a micro type, and a card type (e.g., a secure digital (SD) card or an eXtream (XD) digital card), and at least one type of storage medium of a random access memory (RAM), a static RAM (SRAM), a read-only memory (ROM), a programmable ROM (PROM), an electrically erasable PROM (EEPROM), a magnetic RAM (MRAM), a magnetic disk, and an optical disk type, however, the various embodiments are not limited to these examples.

[0059] According to various embodiments, the output device 126 may provide information related to the operation of the electrical efficiency analysis device 120. In an embodiment, the output device 126 may include a display configured to output visual information. For example, the display may include a liquid crystal display, a thin film transistor liquid crystal display, an organic light emitting diode, a flexible display, a 3-dimensional (3D) display, and a transparent display. The display 120 may also include a touch sensor configured to detect a touch.

[0060] However, this is exemplary, and various embodiments are not limited thereto. For example, information related to the operation of the electric efficiency analysis device 120 may be provided in the form of auditory information. In this case, the output device 126 may also include a sound output device (e.g., a speaker) configured to output an audio signal from the electric efficiency analysis device 120 to the outside.

[0061] According to various embodiments, the processor 128 may control at least one other component of the electric efficiency analyzing device 120 (eg, the communication circuit 122 , the memory 124 , and the output device 126 ) and perform various data processing or calculations.

[0062] According to an embodiment, the processor 128 may provide the electric efficiency (or driving electric efficiency) of the vehicle 10 based on various information obtained through the vehicle diagnostic device 110. The electric efficiency may be calculated as a distance that can be traveled per 1 kWh of electric energy.

[0063] For example, the processor 128 may obtain information about the driving distance and the electric energy consumption in a certain section through the vehicle diagnostic device 110. In connection with this, the processor 128 may calculate the electric efficiency by using the ratio of the electric energy consumption to the driving distance.

[0064] Providing this electrical efficiency can help drivers plan their charging during or before driving. However, even for the same type of vehicle, the electrical efficiency varies depending on road conditions, the driver's driving habits, and vehicle conditions, and the driver cannot discern which factors affect the electrical efficiency only from the provided electrical efficiency.

[0065] In this regard, the processor 128 may analyze factors affecting the electrical efficiency of the vehicle 10 based on various information obtained through the vehicle diagnostic device 110, as described below. For example, the processor 128 may calculate a standard electrical efficiency contribution indicating the degree of influence of the current electrical efficiency of the vehicle 10 on the gain or loss (e.g., increase or decrease) compared to the standard electrical efficiency (e.g., certified electrical efficiency).

[0066] According to an embodiment, the processor 128 may divide (or segment) the section in which the electric energy of the vehicle 10 is consumed into a plurality of sections, and calculate the standard electric efficiency contribution for each section.

[0067] According to an embodiment, the processor 128 may divide the monitoring interval for monitoring the electric energy consumed by the vehicle 10 during driving into a plurality of intervals, and calculate the standard electric efficiency contribution for each interval. In this case, the processor 128 may divide the monitoring interval into a plurality of speed intervals.

[0068] For example, Figure 2aAs shown, the processor 128 can divide the monitoring interval 200 into a first interval 210 corresponding to a first speed range (e.g., 81 km / h or above), a second interval 220 corresponding to a second speed range (e.g., 31 km / h to 80 km / h), and a third interval 230 corresponding to a third speed range (e.g., 1 km / h to 30 km / h) based on the speed of the vehicle 10.

[0069] Subsequently, the processor 128 may calculate a first standard electrical efficiency contribution, a second standard electrical efficiency contribution, and a third standard electrical efficiency contribution for each of the first interval 210 , the second interval 220 , and the third interval 230 , respectively.

[0070] According to an embodiment, the processor 128 may calculate the standard electrical efficiency contribution using the following Equation 1.

[0071] [Formula 1]

[0072] Standard electrical efficiency contribution = power consumption rate * electrical efficiency gain loss value

[0073]

[0074] In formula 1, the power consumption rate It can represent the power consumed on the corresponding road section (E i ) relative to the total power consumption (E T ) ratio, and the electrical efficiency gain loss value Can represent the standard electrical efficiency based on the vehicle And in the corresponding interval of driving distance (M i ) Power consumed (E i ) and calculated the current electrical efficiency Standard electric efficiency with vehicle Here, M S The total achievable driving distance based on the standard electrical efficiency can be represented. For example, the electrical efficiency gain or loss value can be represented as a positive value or a negative value. In addition, an interval with a positive value represents an interval where the electrical efficiency is higher than the standard electrical efficiency, and an interval with a negative value represents an interval where the electrical efficiency is lower than the standard electrical efficiency.

[0075] Can be Figure 3a and Figure 3b And the following equations 2 and 3 are used to explain equation 1.

[0076] like Figure 3a and Figure 3bAs shown, within the overall monitoring interval 300 covering the first interval 310, the second interval 320 and the third interval 330, the difference (④) between the standard electrical efficiency of vehicle 340 and the current electrical efficiency of vehicle 350 can be expressed as the sum of the first standard electrical efficiency contribution (①) for the first interval 310, the second standard electrical efficiency contribution (②) for the second interval 320 and the third standard electrical efficiency contribution (③) for the third interval 330.

[0077] This difference in electrical efficiency (④) can be derived using Equation 2.

[0078] [Formula 2]

[0079]

[0080] Based on the above equation 2, the standard electrical efficiency contribution can be derived using equation 3.

[0081] [Formula 3]

[0082]

[0083] According to an embodiment, examples of standard electrical efficiency contribution calculated based on Formula 1 may be summarized as shown in Table 1 below.

[0084] [Table 1]

[0085]

[0086] Referring to Table 1, it is observed that the sum of the standard electrical efficiency and the standard electrical efficiency contribution of a single interval (e.g., 3-0.3+0.3-0.4=2.6) is equal to the efficiency of the entire interval (e.g., from interval 1 to interval 3) (e.g., 26km / 10kWh=2.6). In addition, it is observed that the efficiency of the first interval (e.g., 2km / kWh) and the efficiency of the third interval (e.g., 2km / kWh) are the same, but the standard electrical efficiency contribution of the first interval (e.g., -0.3) and the standard electrical efficiency of the third interval (e.g., -0.4) are different from each other. This means that the standard electrical efficiency contribution of the same electrical efficiency interval may vary depending on the driving behavior of the driver. In this regard, the processor 128 can accurately analyze the factors affecting efficiency through the standard electrical efficiency contribution and provide it to the driver. As described above, the electrical efficiency analysis device 120 can calculate the power consumption rate and the electrical efficiency gain loss value based on various information obtained by the vehicle diagnostic device 110. However, this is exemplary, and various embodiments are not limited thereto. For example, at least some of the power consumption rate and the electric efficiency gain loss value may be calculated by the vehicle diagnostic device 110 or other external devices and provided to the electric efficiency analysis device 120. According to an embodiment, the processor 128 may divide the monitoring interval into a plurality of speed intervals, and further subdivide each speed interval into a plurality of intervals to calculate the standard efficiency contribution. In this case, the processor 128 may also divide each speed interval into a plurality of speed change intervals. The speed change interval may include at least one of an acceleration interval (e.g., an interval with an acceleration less than 10 km / h per second), a rapid acceleration interval (e.g., an interval with an acceleration greater than or equal to 10 km / h per second), a deceleration interval (e.g., an interval with a deceleration less than 10 kilometers per second), a rapid deceleration interval (e.g., an interval with a deceleration greater than or equal to 1010 km / h per second), or a constant speed interval (e.g., an interval with an average acceleration less than 0.2).

[0087] For example, Figure 2b As shown, the processor 128 can divide the first interval 210 of the monitoring interval 200 into speed change intervals such as a constant speed interval 212, a rapid acceleration interval 214, and a rapid deceleration interval 216, and similarly, divide the second interval 220 of the monitoring interval 200 into speed change intervals such as an acceleration interval 222 and a deceleration interval 224. In addition, the processor 128 can only distinguish certain intervals that meet the predetermined conditions among the constant speed interval 212, the rapid acceleration interval 214, and the rapid deceleration interval 216 in the first interval 210 of the monitoring interval 200 as speed change intervals. Of course, the processor 128 can also only distinguish certain intervals that meet the predetermined conditions among the multiple speed intervals in the monitoring interval 200 as speed change intervals.

[0088] The processor 128 may then calculate the standard electrical efficiency contribution for each speed interval.

[0089] As described above, the standard electric efficiency contribution can be calculated based on the interval (e.g., monitoring interval) in which the vehicle 10 consumes electric energy while traveling. However, this is exemplary, and various embodiments are not limited thereto. For example, additionally or alternatively, the processor 128 can also calculate the standard electric efficiency contribution based on the interval in which energy is consumed even when actual traveling does not occur (e.g., a stopped state).

[0090] According to an embodiment, the processor 128 may calculate the power consumption rate based on the power consumed in the stop state. For example, the processor 128 may calculate the standard power efficiency contribution for the stop state based on the power consumption rate calculated based on the power consumed by the air conditioning device (e.g., cooling device or heating device) and the power efficiency gain loss value calculated for the stop state (e.g., the driving distance is 0 km).

[0091] According to various embodiments, the processor 128 may output information related to the calculated standard electric efficiency contribution (or electric efficiency contribution information).

[0092] According to the implementation mode, Figure 4a As shown, the processor 128 may output electric efficiency contribution information 400, which includes first electric efficiency contribution information 410 related to recent electric efficiency (or recent driving) and second electric efficiency contribution information 420 related to electric efficiency history (or past driving history). In this case, the processor 128 may selectively output the first electric efficiency contribution information 410 or the second electric efficiency contribution information 420 based on user input. Of course, the processor 128 may also output both the first electric efficiency contribution information 410 and the second electric efficiency contribution information 420 based on user input or independently of the user.

[0093] According to an embodiment, the first electric efficiency contribution information 410 may include an average electric efficiency 411 based on recent driving (e.g., recent average electric efficiency: 7.4 km / kWh) and a standard electric efficiency contribution 412 specific to the recently driven, individually monitored speed interval. In addition, the first electric efficiency contribution information 410 may include a graph 414 showing the standard contribution efficiency for the monitored individual speed intervals. This allows the driver to perceive speed intervals that contribute to improving or reducing electric efficiency, ultimately inducing more efficient driver habits.

[0094] Furthermore, additionally or alternatively, while the first electrical efficiency contribution information 410 is being displayed, the processor 128 may provide detailed standard efficiency contribution information for at least one speed zone based on a user input.

[0095] For example, when a specific speed interval (eg, a low speed interval) is selected through the speed interval specific standard electric efficiency contribution 412 or the standard electric efficiency contribution graph 414, as shown in FIG. Figure 4b As shown, the processor 128 can provide a speed change interval specific standard efficiency contribution 416 for a selected speed interval (e.g., a fast acceleration interval, an acceleration interval, a slow acceleration interval, a fast deceleration interval, a deceleration interval, a slow deceleration interval, or a constant speed interval). This allows the driver to perceive actions that reduce (e.g., acceleration actions) or increase (e.g., deceleration actions) efficiency in the low-speed interval.

[0096] According to an embodiment, the processor 128 may also provide information related to gains and losses generated based on the standard electric efficiency contribution when outputting the electric efficiency contribution information. In this regard, the processor 128 may calculate the gains and losses by multiplying the standard electric efficiency contribution by the unit energy cost (e.g., the cost per kWh). In addition, when the processor 128 outputs the electric efficiency contribution information, it may also provide information about the proportion of the intervals with high or low standard electric efficiency contributions in the entire driving range.

[0097] According to an embodiment, the processor 128 may provide a comparison result between a standard electric efficiency contribution based on past driving and a standard electric efficiency contribution based on current driving through the second electric efficiency contribution information 420 related to the electric efficiency history. In this case, the processor 128 may select one of the stored standard electric efficiency contributions for a plurality of past drivings and compare it with the standard electric efficiency contribution for current driving. For example, at least one of a past driving with the best electric efficiency, a past driving just before the current driving, a past driving on a route similar to the current driving, and a past driving performed multiple times within a period of time may be selected as a comparison object to be compared with the current driving.

[0098] For example, Figure 4c As shown, the processor 128 may output second electrical efficiency contribution information 420 including a graph 422 comparing efficiency reduction or increase in current travel with past travel and text information 424 regarding the comparison result.

[0099] Additionally or alternatively, the second electric efficiency contribution information 420 may include an object (e.g., a detailed information check icon 426) that triggers output of detailed information about intervals in which the efficiency has decreased or increased in the current travel compared to the past travel. When a user input to the object is detected, the processor 128 may provide detailed information 428 about intervals in the current travel in which the electric efficiency has decreased or increased compared to the past travel, or about speed change intervals (or actions) in which the electric efficiency has increased or decreased, such as Figure 4dAlthough the detailed comparison result between the electrical efficiencies of past travel and current travel is provided as the detailed information 428 through a radial graph, various embodiments are not limited to this example.

[0100] In the following, reference will be made to Figure 5 and Figure 6 An operating method of the electric efficiency analyzing device 120 according to various embodiments is described in detail.

[0101] Figure 5 is a flowchart illustrating the operation of the electrical efficiency analysis device according to various embodiments. In the following embodiments, the operations may be performed sequentially, but not necessarily in a strictly sequential order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. In addition, depending on the embodiment, at least one operation may be omitted.

[0102] Reference Figure 5 At operation 510, the electric efficiency analysis device 120 (e.g., the processor 128) may monitor the energy consumption of the vehicle. In an embodiment, the electric efficiency analysis device 120 may monitor the energy consumption of the vehicle based on information acquired through the vehicle diagnostic device 110. For example, the electric efficiency analysis device 120 may monitor during an interval (e.g., a driving interval) in which electric energy is consumed due to driving. In another example, the electric efficiency analysis device 120 may perform monitoring even in a state where driving is not actually performed (e.g., a stop interval).
