Description

Technical Field

[0001] The present application relates to the technical field of automobiles, and particularly to a method, device, automobile, and storage medium for determining the average energy consumption of a range-extended vehicle. Background Art

[0002] Currently, the driving information of a vehicle, including driving time, driving distance, average vehicle speed, average power consumption, average fuel consumption, etc., is displayed on the vehicle's display screen, aiming to enable users to obtain their vehicle usage information and adjust their driving behavior.

[0003] For a range-extended vehicle, when the vehicle starts, it involves states such as pushing the vehicle from a standstill to a certain speed, cold starting of high-voltage vehicle components, and idling warm-up of the vehicle range extender. These states will all result in a relatively high short-term average energy consumption of the vehicle, deviating from the vehicle's true average energy consumption per 100 kilometers. To make the energy consumption at the start of the vehicle closer to the true average energy consumption state of the vehicle, the average energy consumption during the vehicle usage cycle can be used as one of the parameters for calculating the average energy consumption per 100 kilometers after each vehicle charge. However, this method does not consider the correlation between power consumption and fuel consumption. Since in addition to the cases of driving the vehicle solely with the battery pack or solely with the range extender generating electricity to drive the vehicle, there is also the case where the battery pack and the range extender jointly drive the vehicle. Especially during the start-up stage of the range extender, there is both power consumption and fuel consumption, and the superposition of the two will cause the short-term average energy consumption of the vehicle to exceed the true average energy consumption per 100 kilometers. The average energy consumption during this period will lose its reference value for users.

[0004] For example: During the start-up process of the range extender, the vehicle is still driven by the battery pack, and the power continues to be output, resulting in power consumption. Moreover, at this time, the catalytic converter is in a heating state, consuming fuel but not generating electricity, and fuel consumption also occurs, resulting in both relatively high average power consumption and average fuel consumption. The superposition of the two far exceeds the actual average energy consumption per 100 kilometers of the vehicle. Summary of the Invention

[0005] The present application provides a method, device, automobile, and storage medium for determining the average energy consumption of a range-extended vehicle to solve the problem that during the start-up stage of the range extender, there is both power consumption and fuel consumption, and the superposition of the two will cause the short-term energy consumption of the vehicle to exceed the true average energy consumption per 100 kilometers.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0027] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] The embodiments of the present application provide a method for determining the average energy consumption of a range-extended vehicle. As Figure 1 shown, it is a flowchart of the method for determining the average energy consumption of a range-extended vehicle according to an embodiment of the present application.

[0029] Step S110, after the range-extended vehicle is awakened, the vehicle mode and the battery pack power of the range-extended vehicle are read in real time, and the target SOC (State of Charge) value corresponding to the vehicle mode is obtained.

[0030] The range-extended vehicle being awakened means that the range-extended vehicle starts.

[0031] The battery pack refers to the power module that supplies power to the range-extended vehicle.

[0032] Vehicle modes, including but not limited to: fuel priority and pure electric priority. Each vehicle mode corresponds to a target SOC value. The target SOC value is the TBC value (To Be Confirmed, value to be set). For example: the target SOC value corresponding to fuel priority is the first SOC value; wherein the first SOC value is an empirical value or a value obtained through experiments, and when set, 50% < first SOC value < 100%. The target SOC value corresponding to pure electric priority is the second SOC value; wherein the second SOC value is also an empirical value or a value obtained through experiments, and when set, 20% < second SOC value < 30%. Furthermore, in different vehicle modes, whether to start the range extender is determined based on the target SOC values ​​corresponding to different vehicle modes, and after the range extender is started, the battery pack charge is maintained at the target SOC value.

[0033] Step S120, when the power of the battery pack is greater than the target SOC value corresponding to the vehicle mode, the battery pack is started to drive the extended-range vehicle to travel, and the initial average power consumption Min(Q, R) corresponding to the extended-range vehicle is determined according to the calibrated average power consumption per unit mileage of the extended-range vehicle, the vehicle power parameters and the vehicle driving parameters.

[0034] Determine whether the currently read battery pack power is greater than the target SOC value corresponding to the current vehicle mode; if yes, execute step S120; if no, execute step S130.

[0035] When the power of the battery pack is greater than the target SOC value corresponding to the vehicle mode, the range-extended vehicle can be driven by pure electric power. At this time, the battery pack can be started to drive the range-extended vehicle.

[0036] The specific method for determining the initial average power consumption Min(Q, R) in the embodiment of the present application will be introduced later, so it will not be repeated here.

[0037] Step S130, when the power of the battery pack is less than or equal to the target SOC value corresponding to the vehicle mode, starting the range extender to drive the extended-range vehicle and keep the battery pack running.

[0038] The range extender includes: a startup phase (during the startup process) and an operation phase. After the range extender is started, it enters the operation phase.

[0039] During the start-up phase of the range extender, the battery pack drives the range-extended vehicle. During the operation phase of the range extender, the range extender generates electricity to drive the range-extended vehicle. At this time, the battery pack only needs to maintain the output target SOC value. What will then happen is that the average power consumption of the range-extended vehicle will gradually decrease, and the average fuel consumption will gradually increase.

[0040] Step S140, before the range extender starts up completely, use the initial average power consumption Min(Q,R) as the average power consumption.

[0041] Before the range extender starts up and during the start-up phase of the range extender, directly output and display the initial average power consumption as the average power consumption. That is to say, before the range extender starts up and during the start-up phase of the range extender, the average fuel consumption is not calculated.

[0042] Furthermore, in the start-up phase of the range extender in the embodiment of the present application, the initial average fuel consumption V corresponding to the range-extended vehicle is not calculated, and only the initial average power consumption Min(Q,R) corresponding to the range-extended vehicle is calculated. This is because in the start-up phase of the range extender, there is both power consumption and fuel consumption. If both are calculated, there will be a problem of superposition of power consumption and fuel consumption, making the average energy consumption of the vehicle much higher than the true average energy consumption per 100 kilometers of the vehicle. Therefore, in the embodiment of the present application, after the range extender starts up completely, the initial average fuel consumption V corresponding to the range-extended vehicle is determined according to the real-time fuel injection amount of the range-extended vehicle and the vehicle driving parameters.

[0043] Step S150, after the range extender starts up completely, determine the initial average fuel consumption V corresponding to the range-extended vehicle according to the real-time fuel injection amount of the range-extended vehicle and the vehicle driving parameters.

[0044] The specific method for determining the initial average fuel consumption V in the embodiment of the present application will be introduced later, so it will not be elaborated here.

[0045] Step S160, determine the energy consumption reference value S according to the calibrated average power consumption per unit mileage M and the reference average power consumption corresponding to the range-extended vehicle when the range extender starts up.

[0046] The calibrated average power consumption per unit mileage M is calculated according to the rated power of the battery pack and the pure electric cruising range I of the range-extended vehicle. Among them, the calibrated average power consumption per unit mileage M = the rated power of the battery pack / the pure electric cruising range I.

[0047] The reference average power consumption can be the average power consumption displayed by the range-extended vehicle when the range extender starts up or the initial average power consumption Min(Q,R) calculated when the range extender starts up.

[0048] Specifically, compare the calibrated average power consumption per unit mileage M of the range-extended vehicle with the reference average power consumption corresponding to the range-extended vehicle when the range extender starts up; use the maximum value of the calibrated average power consumption per unit mileage M and the reference average power consumption of the range-extended vehicle as the energy consumption reference value.

[0049] For example: if Min(Q,R) is greater than M, then Min(Q,R) is used as the energy consumption benchmark value; if Min(Q,R) is less than or equal to M, then M is used as the energy consumption benchmark value.

[0050] Since M is a constant value, during the driving process of the range extender vehicle, the power consumption should be greater than or equal to M. If the average power consumption is less than M, it is not referenceable. Therefore, in the embodiment of the present application, when determining the energy consumption benchmark value, the maximum value between Min(Q,R) and M is selected as the energy consumption benchmark value.

[0051] Step S170, calibrate the initial average power consumption Min(Q,R) and the initial average fuel consumption V respectively according to the energy consumption benchmark value S to obtain the average power consumption and the average fuel consumption.

[0052] After the range extender starts, the calibrated average power consumption and average fuel consumption can be output and displayed on the display screen of the range extender vehicle for the user to refer to. Among them, the sum of the average power consumption and the average fuel consumption is the energy consumption of the range extender vehicle.

[0053] In the embodiment of the present application, when calibrating the initial average power consumption and the initial average fuel consumption, the initial average power consumption, the initial average fuel consumption and the energy consumption benchmark value can be compared. According to different comparison results, different calibration methods are adopted to calibrate the initial average power consumption and the initial average fuel consumption. Moreover, the longer the driving distance of the range extender vehicle, the more accurate the calibration result and the closer it is to the actual average energy consumption per 100 kilometers of the vehicle.

[0054] Comparison result one: when the initial average power consumption Min(Q,R) is greater than the energy consumption benchmark value S, the difference between twice the energy consumption benchmark value S and the initial average power consumption Min(Q,R) is used as the average power consumption; and, calculate the absolute value of the difference between the initial average power consumption Min(Q,R) and the energy consumption benchmark value S, convert the absolute value of the difference into a fuel consumption value and use the converted fuel consumption value as the average fuel consumption.

[0055] That is to say, if Min(Q,R) > S, then the average power consumption = 2*S - Min(Q,R), and the average fuel consumption = (Min(Q,R) - S) / N; where N is the oil-electric conversion coefficient. Among them, the absolute value symbol is not used in the formula because it can be determined that the difference is a positive number. Through calibration, the sum of the average power consumption and the average fuel consumption can maintain the average energy consumption of the whole vehicle at S.

[0056] Comparison result two: When the initial average power consumption Min(Q,R) is less than or equal to the energy consumption reference value S, and the sum of the initial average power consumption Min(Q,R) and the initial average fuel consumption V converted into power consumption is greater than the energy consumption reference value S, the initial average power consumption Min(Q,R) is taken as the average power consumption; and, calculate the absolute value of the difference between the initial average power consumption Min(Q,R) and the energy consumption reference value S, convert the absolute value of the difference into a fuel consumption value and take the converted fuel consumption value as the average fuel consumption.

[0057] That is to say, if Min(Q,R) < S and (Min(Q,R) + V * fuel-electricity conversion coefficient N) > S, then the average power consumption = Min(Q,R), and the average fuel consumption = (S - Min(Q,R)) / N. Among them, the absolute value symbol is not used in the formula because it can be determined that the difference is a positive number. Through calibration, the sum of the average power consumption and the average fuel consumption can maintain the average vehicle energy consumption at S.

[0058] Comparison result three: When the sum of the initial average power consumption Min(Q,R) and the initial average fuel consumption converted into power consumption is less than or equal to the energy consumption reference value S, the initial average power consumption Min(Q,R) is taken as the average power consumption and the initial average fuel consumption V is taken as the average fuel consumption.

[0059] That is to say, if Min(Q,R) < S and (Min(Q,R) + V * fuel-electricity conversion coefficient N) < S, then the average power consumption = Min(Q,R), and the average fuel consumption = V.

[0060] In the embodiments of the present application, after the range extender vehicle starts to drive, the average power consumption and the average energy consumption are updated every preset energy consumption update interval mileage and displayed on the display screen. The energy consumption update interval mileage is an empirical value or a value obtained through experiments. For example: the preset energy consumption update interval mileage is 100 meters, that is to say, every 100 meters of driving, the average power consumption and the average fuel consumption are updated. Among them, the range extender vehicle has a driving mileage calculation function.

[0061] In the embodiments of the present application, since the process of switching from pure electric drive of the battery pack to range extender drive is relatively short, the initial average power consumption and the initial average fuel consumption can be calibrated only during this short time. Specifically, according to the real-time vehicle speed of the range extender vehicle included in the vehicle driving parameters and the preset initial driving distance of the vehicle, determine the driving distance interval to be calibrated for energy consumption; within the driving distance interval, calibrate the initial average power consumption and the initial average fuel consumption respectively.

[0062] Specifically, to determine the driving distance interval to be calibrated for energy consumption, the real driving mileage P of the range extender vehicle can be calculated by integration according to the real-time vehicle speed of the range extender vehicle (i.e., at the moment when the range extender starts, the real driving mileage P of the range extender vehicle); when starting the range extender, the driving distance interval is determined according to the real driving mileage P of the range extender vehicle and the initial driving distance of the vehicle; wherein, the driving distance interval is: starting from starting the range extender and ending at (preset value / W) times the initial driving distance of the vehicle; W is a positive integer greater than zero; W is the value obtained after rounding the ratio of the real driving mileage P and the initial driving distance of the vehicle when the range extender starts. In this embodiment, within the first energy consumption update interval mileage after the range extender starts, the average power consumption and the average energy consumption are calibrated.

[0063] Further, the preset value is an empirical value or a value obtained through experiments. For example: the preset value can be set to 10. Wherein, the value of preset value / W multiplied by the initial driving distance can represent the calibration mileage before the range extender vehicle outputs the average power consumption and the average fuel consumption after the range extender starts, that is: the driving distance interval. In this way, after the range extender starts, when the range extender vehicle travels within the driving distance interval, the initial average power consumption and the initial average fuel consumption can be calibrated. Further, when the range extender starts, if the current actual driving distance of the range extender vehicle is relatively long, the value of the average fuel consumption plus the average power consumption will not be too large; if the current actual driving distance of the range extender vehicle is relatively short, the value of the average fuel consumption plus the average power consumption will be relatively large. Therefore, the calibration algorithm is executed within a relatively short distance after the range extender starts in the embodiments of the present application. Further, the driving distance interval for executing the calibration algorithm in the embodiments of the present application is affected by the initial driving distance of the vehicle, and the calibration value of the initial driving distance of the vehicle is affected by the energy consumption fluctuation range of the vehicle. Different vehicles have different power performances and different energy consumptions. For range extender vehicles with large energy consumption fluctuations affected by road conditions, driving styles, and weather, that is, the initial driving distance of the range extender vehicle with large energy consumption fluctuations is greater than that of the range extender vehicle with small energy consumption fluctuations.

[0064] Further, the time interval for integral calculation is a software operation cycle. The software operation cycle refers to the time period formed from when the range extender vehicle is awakened to the starting point of the current sampling cycle. The length of the sampling cycle can be determined according to requirements.

[0065] Further, outside the driving distance interval, the calibration of the initial average power consumption and the initial average fuel consumption is stopped, and the initial average power consumption and the initial average fuel consumption are directly displayed.

[0066] In an embodiment of the present application, a calibration exit mechanism may also be set. Specifically, when the initial average power consumption is less than or equal to the energy consumption benchmark value for a continuous preset number of times, the calibration of the initial average power consumption and the initial average fuel consumption is stopped. The preset number of times is an empirical value or a value obtained through experiments. For example, the preset number of times is two times.

[0067] Further, after stopping the calibration of the initial average power consumption and the initial average fuel consumption, the initial average power consumption and the initial average fuel consumption are directly displayed.

[0068] In an embodiment of the present application, after the range extender vehicle is awakened, the vehicle mode and the battery pack power of the range extender vehicle are read in real time, and the target SOC value corresponding to the vehicle mode is obtained; when the battery pack power is greater than the target SOC value corresponding to the vehicle mode, the battery pack is started to drive the range extender vehicle, and according to the calibrated average power consumption per unit mileage, vehicle power parameters, and vehicle driving parameters of the range extender vehicle, the initial average power consumption corresponding to the range extender vehicle is determined; when the battery pack power is less than or equal to the target SOC value corresponding to the vehicle mode, the range extender is started to drive the range extender vehicle and keep the battery pack running; before the range extender is started, the initial average power consumption is used as the average power consumption; after the range extender is started, according to the real-time fuel injection volume of the range extender vehicle and the vehicle driving parameters, the initial average fuel consumption corresponding to the range extender vehicle is determined; according to the calibrated average power consumption per unit mileage and the benchmark average power consumption corresponding to the range extender vehicle when the range extender is started, the energy consumption benchmark value is determined; according to the energy consumption benchmark value, the initial average power consumption and the initial average fuel consumption are calibrated respectively to obtain the average power consumption and the average fuel consumption. The embodiment of the present application does not adopt the theoretical calculation methods of average power consumption and average fuel consumption, that is: average power consumption = power consumption of the driving distance / driving distance, unit: kwh / 100km; average fuel consumption = fuel consumption of the driving distance / driving distance, unit: L / 100km; nor does it adopt the improved calculation methods of average power consumption and average fuel consumption, that is: taking the average power consumption and average fuel consumption in the later period of using the vehicle after the previous charging as the calculation parameters of the current average power consumption and average fuel consumption, to reduce the excessively high average power consumption and average fuel consumption when the battery pack and the range extender jointly drive the vehicle. The embodiment of the present application calculates the initial average power consumption and the initial average fuel consumption with reference to the power state of the vehicle, the vehicle mode, and the driving distance of the current trip, and calculates the initial average fuel consumption after the range extender is started, avoiding the period of superposition of average power consumption and average fuel consumption, and also using the energy consumption benchmark value to calibrate the initial average power consumption and the initial average fuel consumption, making the sum of the calibrated average power consumption and average fuel consumption closer to the actual average energy consumption per 100 kilometers of the range extender vehicle.

[0069] Furthermore, since the range-extended vehicle first runs purely on electricity after the start of the current trip and then switches to the range extender to generate electricity to drive the vehicle, this switching process will cause the problem of superposition of the average power consumption and average fuel consumption of the whole vehicle. In view of this problem, when calculating the average power consumption and average fuel consumption in the embodiments of the present application, the power state of the vehicle at the start of the current trip, the vehicle mode, and the driving distance of the current trip are considered, and combined with the start-stop control strategy (start and stop strategy of the range extender) of the range extender under different vehicle modes, the average power consumption and average fuel consumption are calculated to ensure that the sum of the calculated average power consumption and average fuel consumption fits the real fuel consumption per 100 kilometers of the range-extended vehicle, giving a reasonable reference value to the user and avoiding misleading the user.

[0070] To make the embodiments of the present application clearer and easier to understand, the embodiments of the present application will be further described below.

[0071] First, the parameters involved in the embodiments of the present application will be introduced as follows:

[0072] The vehicle power parameters include: the real-time voltage and real-time current of the battery pack. Among them, the real-time voltage and real-time current can be the voltage and current collected in each sampling period within the software operation cycle. The software operation cycle refers to the time period formed from the wake-up of the range-extended vehicle to the start point of the current sampling period. The length of the sampling period can be determined according to requirements.

[0073] The vehicle driving parameters include: the real-time vehicle speed of the range-extended vehicle and the preset initial driving distance of the vehicle. Among them, the real-time vehicle speed can be the vehicle speed collected in each sampling period within the software operation cycle. The initial driving distance of the vehicle is a preset parameter. The initial driving distance of the vehicle can be an empirical value or a value obtained through experiments. This value will not be very large, as too large a value will cause the vehicle's actual energy consumption to deviate from the actual value for a long time when it is very high, and too small a value will not play the role of averaging the calculation. The initial driving distance of the vehicle can be set to a value between 5 km and 10 km.

[0074] The real-time fuel injection quantity refers to the fuel injection quantity collected in each sampling period within the software operation cycle.

[0075] Next, the process of determining the initial average power consumption corresponding to the range-extended vehicle according to the calibrated average power consumption per unit mileage, vehicle power parameters, and vehicle driving parameters of the range-extended vehicle will be described. As Figure 2 shown, it is a flowchart of the steps for determining the initial average power consumption according to an embodiment of the present application.

[0076] Step S210, according to the real-time voltage and real-time current of the battery pack, integrally calculate the real power consumption O of the range-extended vehicle; and according to the real-time vehicle speed of the range-extended vehicle, integrally calculate the real driving mileage P of the range-extended vehicle. Among them, the time interval for integral calculation is one software operation cycle.

[0077] Step S220: Using the pull-average calculation method, calculate the first candidate average power consumption Q corresponding to the range extender vehicle according to the calibrated average power consumption M per unit mileage of the range extender vehicle, the initial driving distance of the vehicle, the actual power consumption O, and the actual driving mileage P.

[0078] For example: Calculate the first candidate average power consumption Q (unit: kwh / 100km) using the following formula:

[0079]

[0080] Step S230: Calculate the second candidate average power consumption R corresponding to the range extender vehicle according to the actual power consumption O and the actual driving mileage P of the range extender vehicle.

[0081] For example: Calculate the second candidate average power consumption R (unit: kwh / 100km) using the following formula:

[0082]

[0083] Step S240: Take the minimum value of the first candidate average power consumption Q and the second candidate average power consumption R as the initial average power consumption Min(Q, R) corresponding to the range extender vehicle.

[0084] The first candidate average power consumption Q is the value calculated using the pull-average algorithm and can reflect the power consumption over a period of time. The second candidate average power consumption R is the average power consumption at a certain point in time, and its change at different times is not stable enough, sometimes large and sometimes small. Therefore, in the embodiments of the present application, the minimum value of Q and R is selected as the initial average power consumption, so that the initial average power consumption can remain relatively stable at different times.

[0085] The following describes the process of determining the initial average fuel consumption corresponding to the range extender vehicle according to the real-time fuel injection amount and the vehicle driving parameters of the range extender vehicle. As Figure 3 shown, it is a flowchart of the steps for determining the initial average fuel consumption according to an embodiment of the present application.

[0086] Step S310: Determine whether the range extender has completed starting according to the preset range extender starting determination condition; if so, execute Step S320; if not, continue to execute Step S310.

[0087] The determination conditions for starting the range extender include: the range extender of the range-extended vehicle is in the starting state; and / or, the output current of the generator of the range-extended vehicle is greater than or equal to zero; and / or, the catalytic converter of the range-extended vehicle is in the heating state. Among them, when any of the range extender start determination conditions is met, it is determined that the range extender has not been started yet. Accordingly, if none of the above range extender start determination conditions are met, it is determined that the range extender has been started.

[0088] The output current of the generator being greater than or equal to 0 A indicates that there is a starting requirement for the range extender. Further, the generator is connected to the engine of the range extender. When starting the range extender, the generator supplies power to the engine, and the output current is greater than or equal to 0 A. After the range extender is started, the output power of the generator becomes negative.

[0089] The catalytic converter being in the heating state indicates that the range extender is starting. Because the range extender needs to be heated when starting, and it can operate normally only when heated to a certain extent.

[0090] Step S320, after determining that the range extender has been started, calculate the fuel consumption U of the range-extended vehicle by integral according to the real-time fuel injection amount of the range-extended vehicle. Among them, the time interval for integral calculation is the software operation cycle.

[0091] Step S330, calculate the actual driving mileage P of the range-extended vehicle by integral according to the real-time vehicle speed of the range-extended vehicle. Among them, the time interval for integral calculation is the software operation cycle.

[0092] Step S340, calculate the initial average fuel consumption V corresponding to the range-extended vehicle according to the fuel consumption U of the range-extended vehicle and the actual driving mileage P of the range-extended vehicle.

[0093] For example: calculate the initial average fuel consumption V (unit: L / 100km) using the following formula:

[0094]
