Description
技术领域Technical Field
本申请涉及汽车技术领域,尤其涉及一种增程汽车的平均能耗确定方法、装置、汽车和存储介质。The present application relates to the field of automobile technology, and in particular to a method, device, automobile and storage medium for determining average energy consumption of a range-extended vehicle.
背景技术Background technique
目前,在汽车的显示屏中会显示汽车的行程信息,包括:行驶时间、行驶距离、平均车速、平均电耗、平均油耗等信息,目的在于使用户获取自己的用车信息,调整自己的驾驶行为。At present, the car's travel information is displayed on the car's display screen, including: driving time, driving distance, average speed, average power consumption, average fuel consumption and other information. The purpose is to enable users to obtain their own car information and adjust their driving behavior.
对于增程汽车而言,在汽车刚启动时,涉及车辆从静止推动到一定车速、车辆高压零部件冷启动、车辆增程器怠速暖机等状态,这些状态都会导致车辆的短时平均能耗较高,脱离车辆真实的百公里平均能耗状态。为了使汽车刚启动时的能耗更贴近车辆的真实平均能耗状态,可以在车辆每次充电后,将用车周期内的平均能耗作为计算百公里平均能耗的参数之一,但是这种方式未考虑电耗和油耗之间的关联性,因为车辆除了单独使用电池包纯电驱车行驶或者单独使用增程器发电驱车行驶的情况,还存在电池包和增程器共同驱动车辆行驶的情况,由其是在增程器的启动阶段,既有电量消耗,又有燃油消耗,两者叠加将导致车辆的短时平均能耗超出真实的百公里平均能耗状态,这一时段的平均能耗对用户而言将会失去参考价值。For extended-range vehicles, when the vehicle is just started, it involves pushing the vehicle from a standstill to a certain speed, cold starting of the vehicle's high-voltage components, and idling warm-up of the vehicle's range extender. These states will cause the vehicle's short-term average energy consumption to be high, deviating from the vehicle's actual average energy consumption per 100 kilometers. In order to make the energy consumption of the vehicle when it is just started closer to the vehicle's actual average energy consumption, the average energy consumption during the vehicle's use cycle can be used as one of the parameters for calculating the average energy consumption per 100 kilometers after each charge of the vehicle. However, this method does not take into account the correlation between power consumption and fuel consumption, because in addition to using the battery pack alone to drive the vehicle purely electrically or using the range extender alone to generate electricity and drive the vehicle, there is also a situation where the battery pack and the range extender are used together to drive the vehicle. In particular, during the start-up phase of the range extender, there is both power consumption and fuel consumption. The superposition of the two will cause the vehicle's short-term average energy consumption to exceed the actual average energy consumption per 100 kilometers, and the average energy consumption during this period will lose its reference value for users.
例如:在增程器的启动过程中,依旧由电池包驱动车辆,电量持续输出,产生电耗,而且此时催化器在加热状态下,耗油却不发电,油耗也在发生,导致平均电耗和平均油耗均较高,两者叠加远超车辆的实际百公里能耗状态。For example: during the startup process of the range extender, the vehicle is still driven by the battery pack, and the power is continuously output, generating electricity consumption. At this time, the catalyst is in a heated state, consuming fuel but not generating electricity, and fuel consumption is still occurring, resulting in high average electricity consumption and average fuel consumption. The combination of the two far exceeds the vehicle's actual energy consumption per 100 kilometers.
发明内容Summary of the invention

电池包是指为增程汽车供电的电源模组。The battery pack refers to the power module that provides power for extended-range vehicles.
车辆模式,包括但不限于:燃油优先和纯电优先。每种车辆模式对应一个目标SOC值。目标SOC值为TBC值(To Be Confirmed,待设置的值)。例如:燃油优先对应目标SOC值为第一SOC值;其中,第一SOC值为经验值或者通过实验获得的值,在设置时,50%<第一SOC值<100%。纯电优先对应的目标SOC值为第二SOC值;其中,第二SOC值同样为经验值或者通过实验获得的值,在设置时,20%<第二SOC值<30%。进一步地,在不同车辆模式下,基于不同车辆模式对应的目标SOC值确定是否启动增程器,增程器启动后保证电池包电量维持在目标SOC值。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.
步骤S120,在所述电池包电量大于所述车辆模式对应的目标SOC值时,启动电池包用以驱动所述增程汽车行驶,并且,根据所述增程汽车的标定单位里程平均电耗、车辆电量参数和车辆行驶参数,确定所述增程汽车对应的初始平均电耗Min(Q,R)。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.
判定当前读取的电池包电量是否大于当前车辆模式对应的目标SOC值;如果是,则执行步骤S120;如果否,则执行步骤S130。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.
在所述电池包电量大于所述车辆模式对应的目标SOC值时,可以采用纯电驱动增程汽车行驶,此时,可以启动电池包,使电池包驱动增程汽车行驶。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.
本申请实施例具体定初始平均电耗Min(Q,R)的方式将在后面进行介绍,故在此不做赘述。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.
步骤S130,在所述电池包电量小于或者等于所述车辆模式对应的目标SOC值时,启动增程器用以驱动所述增程汽车行驶并且保持所述电池包运行。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.
增程器包括:启动阶段(启动过程中)和运行阶段。其中,增程器在启动完成之后,开始进入运行阶段。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.
在增程器启动阶段,由电池包驱动增程汽车行驶,在增程器运行阶段,由增程器发电来驱动增程汽车行驶,而且此时的电池包保持输出目标SOC值即可,随即出现的是,增程汽车的平均电耗会逐步降低,平均油耗会逐步升高。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.
步骤S140,在所述增程器启动完成之前,将所述初始平均电耗Min(Q,R)作为平均电耗。Step S140, before the range extender is started, the initial average power consumption Min(Q, R) is used as the average power consumption.
在增程器启动之前以及在增程器启动阶段,都直接将初始平均电耗作为平均电耗输出并且显示。也即是说,在增程器启动之前以及在增程器启动阶段,不计算平均油耗。Before the range extender is started and during the start-up phase of the range extender, the initial average power consumption is directly output and displayed as the average power consumption. That is, before the range extender is started and during the start-up phase of the range extender, the average fuel consumption is not calculated.
进一步地,本申请实施例在增程器启动阶段,不计算增程汽车对应的初始平均油耗V,只计算增程汽车对应的初始平均电耗Min(Q,R),这是因为在增程器启动阶段,既存在电耗,又存在油耗,如果都进行计算,则会出现电耗和油耗叠加的问题,使车辆的平均能耗远高于车辆真实的百公里平均能耗。因此,本申请实施例在增程器启动完成之后,才开始根据所述增程汽车的增程汽车的实时喷油量和所述车辆行驶参数,确定所述增程汽车对应的初始平均油耗V。Furthermore, in the range extender startup phase, the embodiment of the present application does not calculate the initial average fuel consumption V corresponding to the range extender vehicle, but only calculates the initial average power consumption Min(Q,R) corresponding to the range extender vehicle. This is because in the range extender startup phase, there is both power consumption and fuel consumption. If both are calculated, the problem of power consumption and fuel consumption being superimposed will occur, making the average energy consumption of the vehicle much higher than the actual average energy consumption per 100 kilometers of the vehicle. Therefore, in the embodiment of the present application, after the range extender is started, the initial average fuel consumption V corresponding to the range extender vehicle is determined based on the real-time fuel injection amount of the range extender vehicle and the vehicle driving parameters.
步骤S150,在所述增程器启动完成之后,根据所述增程汽车的实时喷油量和所述车辆行驶参数,确定所述增程汽车对应的初始平均油耗V。Step S150, after the range extender is started, the initial average fuel consumption V corresponding to the range extender vehicle is determined according to the real-time fuel injection amount of the range extender vehicle and the vehicle driving parameters.
本申请实施例具体定初始平均油耗V的方式将在后面进行介绍,故在此不做赘述。The specific method of determining the initial average fuel consumption V in the embodiment of the present application will be introduced later, so it will not be described here in detail.
步骤S160,根据标定单位里程平均电耗M和所述增程器启动时所述增程汽车对应的基准平均电耗,确定能耗基准值S。Step S160, determining an 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 extended-range vehicle when the range extender is started.
所述标定单位里程平均电耗M是根据所述电池包的额定电量和所述增程汽车的纯电续航行驶里程I计算得到的。其中,标定单位里程平均电耗M=电池包的额定电量/纯电续航行驶里程I。The calibrated average power consumption per unit mileage M is calculated based on the rated power of the battery pack and the pure electric cruising range I of the extended-range vehicle. Among them, the calibrated average power consumption per unit mileage M=rated power of the battery pack/pure electric cruising range I.
基准平均电耗可以是增程器启动时增程汽车显示的平均电耗或者为增程器启动时计算出的初始平均电耗Min(Q,R)。The reference average power consumption may be the average power consumption displayed by the range-extended vehicle when the range extender is started or the initial average power consumption Min(Q, R) calculated when the range extender is started.
具体而言,比较所述增程汽车的标定单位里程平均电耗M和所述增程器启动时所述增程汽车对应的基准平均电耗;将所述增程汽车的标定单位里程平均电耗M和所述基准平均电耗中的最大值,作为所述能耗基准值。Specifically, the calibrated average power consumption per unit mileage M of the extended-range vehicle is compared with the benchmark average power consumption corresponding to the extended-range vehicle when the range extender is started; and the maximum value of the calibrated average power consumption per unit mileage M of the extended-range vehicle and the benchmark average power consumption is used as the energy consumption benchmark value.
例如:如果Min(Q,R)大于M,则将Min(Q,R)作为能耗基准值;如果Min(Q,R)小于或者等于M,则将M作为能耗基准值。For example: if Min(Q,R) is greater than M, Min(Q,R) is used as the energy consumption benchmark value; if Min(Q,R) is less than or equal to M, M is used as the energy consumption benchmark value.
由于M为不变值,增程汽车在驾驶过程中,电耗应大于或者等于M,如果平均电耗小于M,则不具有参考性。所以,本申请实施例在确定能耗基准值时,选择Min(Q,R)和M中的最大值作为能耗基准值。Since M is a constant value, the power consumption of the extended-range vehicle during driving should be greater than or equal to M. If the average power consumption is less than M, it is not of reference value. Therefore, when determining the energy consumption reference value, the embodiment of the present application selects the maximum value of Min(Q, R) and M as the energy consumption reference value.
步骤S170,根据所述能耗基准值S,分别校准所述初始平均电耗Min(Q,R)和所述初始平均油耗V,得到平均电耗以及平均油耗。Step S170, according to the energy consumption reference value S, calibrate the initial average power consumption Min(Q, R) and the initial average fuel consumption V respectively to obtain the average power consumption and the average fuel consumption.
在增程器启动之后,可以将校准后得到的平均电耗和平均油耗都输出并显示在增程汽车的显示屏中,供用户参考使用。其中,平均电耗和平均油耗的和,即是增程汽车的能耗。After the range extender is started, the average power consumption and average fuel consumption obtained after calibration can be output and displayed on the display screen of the range extender for user reference. The sum of the average power consumption and the average fuel consumption is the energy consumption of the range extender.
在本申请实施例中,在校准所述初始平均电耗和所述初始平均油耗时,可以比较初始平均电耗、初始平均油耗和能耗基准值,根据不同的比较结果,采用不同的校准方式,校准所述初始平均电耗和所述初始平均油耗,而且增程汽车的行驶距离越长,校准结果越准确,越贴合车辆真实的百公里平均能耗。In an 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 baseline value can be compared. According to different comparison results, different calibration methods are used to calibrate the initial average power consumption and the initial average fuel consumption. Moreover, the longer the driving distance of the extended-range vehicle, the more accurate the calibration result is, and the closer it fits the vehicle's actual average energy consumption per 100 kilometers.
比较结果一:在所述初始平均电耗Min(Q,R)大于所述能耗基准值S时,将二倍的所述能耗基准值S与所述初始平均电耗Min(Q,R)的差值作为所述平均电耗;并且,计算所述初始平均电耗Min(Q,R)和所述能耗基准值S的差值绝对值,将所述差值绝对值转换为油耗值并且将转换出的油耗值作为所述平均油耗。Comparison result 1: When the initial average power consumption Min(Q, R) is greater than the energy consumption reference value S, the difference between twice the energy consumption reference value S and the initial average power consumption Min(Q, R) is taken as the average power consumption; and the absolute value of the difference between the initial average power consumption Min(Q, R) and the energy consumption reference value S is calculated, the absolute value of the difference is converted into a fuel consumption value and the converted fuel consumption value is taken as the average fuel consumption.
也即是说,如果Min(Q,R)>S,则平均电耗=2*S-Min(Q,R),平均油耗=(Min(Q,R)-S)/N;其中,N为油电转换系数。其中,算式中未使用绝对值符号,是因为可以确定差值为正数。通过校准,平均电耗和平均油耗的和,可以将整车平均能耗维持在S。That is to say, if Min(Q,R)>S, then average power consumption=2*S-Min(Q,R), average fuel consumption=(Min(Q,R)-S)/N; where N is the fuel-to-electric conversion coefficient. The absolute value symbol is not used in the formula because the difference can be determined to be 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.
比较结果二:在所述初始平均电耗Min(Q,R)小于或者等于所述能耗基准值S,并且,所述初始平均电耗Min(Q,R)与转换为电耗的所述初始平均油耗V的和值大于所述能耗基准值S时,将所述初始平均电耗Min(Q,R)作为所述平均电耗;并且,计算所述初始平均电耗Min(Q,R)和所述能耗基准值S的差值绝对值,将所述差值绝对值转换为油耗值并且将转换出的油耗值作为所述平均油耗。Comparison result two: when the initial average electricity consumption Min(Q, R) is less than or equal to the energy consumption reference value S, and the sum of the initial average electricity consumption Min(Q, R) and the initial average fuel consumption V converted into electricity consumption is greater than the energy consumption reference value S, the initial average electricity consumption Min(Q, R) is used as the average electricity consumption; and the absolute value of the difference between the initial average electricity consumption Min(Q, R) and the energy consumption reference value S is calculated, the absolute value of the difference is converted into a fuel consumption value and the converted fuel consumption value is used as the average fuel consumption.
也即是说,如果Min(Q,R)<S且(Min(Q,R)+V*油电转换系数N)>S,则平均电耗=Min(Q,R),平均油耗=(S-Min(Q,R))/N。其中,算式中未使用绝对值符号,是因为可以确定差值为正数。通过校准,平均电耗和平均油耗的和,可以将整车平均能耗维持在S。That is to say, if Min(Q,R)<S and (Min(Q,R)+V*oil-to-electricity conversion coefficient N)>S, then average power consumption=Min(Q,R), average fuel consumption=(S-Min(Q,R))/N. 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.
比较结果三:在所述初始平均电耗Min(Q,R)和转换为电耗的所述初始平均油耗的和值小于或者等于所述能耗基准值S时,将所述初始平均电耗Min(Q,R)作为所述平均电耗并且将所述初始平均油耗V作为所述平均油耗。Comparison result three: when the sum of the initial average electricity consumption Min(Q, R) and the initial average fuel consumption converted into electricity consumption is less than or equal to the energy consumption reference value S, the initial average electricity consumption Min(Q, R) is used as the average electricity consumption and the initial average fuel consumption V is used as the average fuel consumption.
也即是说,如果Min(Q,R)<S且(Min(Q,R)+V*油电转换系数N)<S,则平均电耗=Min(Q,R),平均油耗=V。That is to say, if Min(Q,R)<S and (Min(Q,R)+V*oil-to-electricity conversion coefficient N)<S, then the average electricity consumption=Min(Q,R) and the average fuel consumption=V.
在本申请实施例中,在增程汽车开始行驶之后,每间隔预设的能耗更新间隔里程,更新一次平均电耗和平均能耗并且显示在显示屏中。能耗更新间隔里程为经验值或者通过实验获得的值。例如:预设能耗更新间隔里程为100米,也即是说,每行驶100米,更新一次平均电耗和平均油耗。其中,增程汽车具有行驶里程计算功能。In the embodiment of the present application, after the extended-range vehicle starts to travel, the average power consumption and average energy consumption are updated once at 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, the average power consumption and average fuel consumption are updated once every 100 meters traveled. Among them, the extended-range vehicle has a mileage calculation function.
在本申请实施例中,由于从电池包的纯电驱动切换到增程器驱动的过程较为短暂,所以可以只在这一短暂时间内校准初始平均电耗和初始平均油耗。具体而言,根据所述车辆行驶参数中包括的所述增程汽车的实时车速以及预设的车辆初始已行驶距离,确定待能耗校准的行驶距离区间;在所述行驶距离区间内,分别校准所述初始平均电耗和所述初始平均油耗。In the embodiment 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 initial average fuel consumption can be calibrated only in this short period of time. Specifically, the driving distance interval to be calibrated for energy consumption is determined based on the real-time speed of the range extender vehicle included in the vehicle driving parameters and the preset initial vehicle travel distance; within the driving distance interval, the initial average power consumption and the initial average fuel consumption are calibrated respectively.
具体而言,确定待能耗校准的行驶距离区间,可以根据所述增程汽车的实时车速,积分计算所述增程汽车的真实行驶里程P(即:增程器启动时刻,增程汽车的真实行驶里程P);在启动所述增程器时,根据所述增程汽车的真实行驶里程P和所述车辆初始已行驶距离,确定所述行驶距离区间;其中,所述行驶距离区间为:从启动所述增程器开始,行驶到(预设值/W)倍的所述车辆初始已行驶距离结束;W为大于零的正整数;W为所述增程器启动时所述真实行驶里程P和所述车辆初始已行驶距离的比值在四舍五入之后得到的值。本实施例在增程器启动后的第一个能耗更新间隔里程内,校准得到平均电耗和平均能耗。Specifically, to determine the driving distance interval for energy consumption calibration, the real driving mileage P of the extended-range vehicle (i.e., the real driving mileage P of the extended-range vehicle at the start-up time of the range extender) can be integrally calculated based on the real-time speed of the extended-range vehicle; when the range extender is started, the driving distance interval is determined based on the real driving mileage P of the extended-range vehicle and the initial distance traveled by the vehicle; wherein, the driving distance interval is: starting from the start of the range extender, and ending when the vehicle travels to (preset value/W) times the initial distance traveled; W is a positive integer greater than zero; W is the value obtained by rounding the ratio of the real driving mileage P to the initial distance traveled by the vehicle when the range extender is started. In this embodiment, the average power consumption and average energy consumption are calibrated within the first energy consumption update interval mileage after the range extender is started.
进一步地,该预设值为经验值或者通过实验获得的值。例如:预设值可以设置为10。其中,预设值/W的值乘以初始已行驶距离可以代表增程器启动后增程汽车进行平均电耗和平均油耗输出前的校准里程,即:行驶距离区间,这样在增程器启动后,增程汽车行驶在行驶距离区间内,可以对初始平均电耗和初始平均油耗执行校准。进一步地,在增程器启动时,如果增程汽车当前实际已行驶距离较长,则平均油耗叠加平均电耗的值不会过大,如果增程汽车当前实际已行驶距离较短,则平均油耗叠加平均电耗的值较大,因此本申请实施例在增程器启动后的较短距离内执行校准算法。进一步地,本申请实施例执行校准算法的行驶距离区间受车辆初始已行驶距离的影响,车辆初始已行驶距离的标定值受车辆能耗波动范围的影响,不同车辆的动力性不同,能耗也不同,针对车辆能耗受路况、驾驶风格、天气影响较大,即车辆能耗波动范围大的增程汽车的车辆初始已行驶距离大于车辆能耗波动范围小的增程汽车的车辆初始已行驶距离。Furthermore, the preset value is an empirical value or a value obtained through experiments. For example, the preset value can be set to 10. Among them, the value of the preset value/W multiplied by the initial traveled distance can represent the calibration mileage before the extended-range vehicle outputs the average power consumption and the average fuel consumption after the range extender is started, that is, the driving distance interval. In this way, after the range extender is started, the extended-range vehicle travels within the driving distance interval, and the initial average power consumption and the initial average fuel consumption can be calibrated. Furthermore, when the range extender is started, if the actual distance traveled by the extended-range vehicle is relatively long, the value of the average fuel consumption superimposed on the average power consumption will not be too large. If the actual distance traveled by the extended-range vehicle is relatively short, the value of the average fuel consumption superimposed on the average power consumption is relatively large. Therefore, the embodiment of the present application executes the calibration algorithm within a shorter distance after the range extender is started. Furthermore, the driving distance interval for executing the calibration algorithm in the embodiment 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 fluctuation range of the vehicle's energy consumption. Different vehicles have different dynamic properties and energy consumption. The vehicle energy consumption is greatly affected by road conditions, driving style, and weather, that is, the initial driving distance of an extended-range vehicle with a large fluctuation range of vehicle energy consumption is greater than the initial driving distance of an extended-range vehicle with a small fluctuation range of vehicle energy consumption.
进一步地,积分计算的时间区间为一个软件运行周期。软件运行周期是指从增程汽车被唤醒到当前采样周期的起点形成的时间段。采样周期的长度可以根据需求而定。Furthermore, the time interval for integral calculation is a software operation cycle. The software operation cycle refers to the time period from when the extended-range vehicle is awakened to the starting point of the current sampling cycle. The length of the sampling cycle can be determined according to demand.
进一步地,在行驶距离区间外,停止校准所述初始平均电耗和所述初始平均油耗,直接显示所述初始平均电耗和所述初始平均油耗。Furthermore, 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.
在本申请实施例中,还可以设置校准退出机制。具体而言,在连续预设次数出现所述初始平均电耗小于或者等于所述能耗基准值时,停止校准所述初始平均电耗和所述初始平均油耗。在预设次数为经验值或者通过实验获得的值。例如:预设次数为两次。In the 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 reference value for a preset number of consecutive 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.
进一步地,在停止校准所述初始平均电耗和所述初始平均油耗之后,直接显示所述初始平均电耗和所述初始平均油耗。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.
在本申请实施例中,在增程汽车被唤醒之后,实时读取所述增程汽车的车辆模式和电池包电量并且获取所述车辆模式对应的目标SOC值;在所述电池包电量大于所述车辆模式对应的目标SOC值时,启动电池包用以驱动所述增程汽车行驶,并且,根据所述增程汽车的标定单位里程平均电耗、车辆电量参数和车辆行驶参数,确定所述增程汽车对应的初始平均电耗;在所述电池包电量小于或者等于所述车辆模式对应的目标SOC值时,启动增程器用以驱动所述增程汽车行驶并且保持所述电池包运行;在所述增程器启动完成之前,将所述初始平均电耗作为平均电耗;在所述增程器启动完成之后,根据所述增程汽车的实时喷油量和所述车辆行驶参数,确定所述增程汽车对应的初始平均油耗;根据所述标定单位里程平均电耗和所述增程器启动时所述增程汽车对应的基准平均电耗,确定能耗基准值;根据所述能耗基准值,分别校准所述初始平均电耗和所述初始平均油耗,得到平均电耗以及平均油耗。本申请实施例并未采用理论上的平均电耗和平均油耗的计算方法,即:平均电耗=行程行驶距离的电耗/行驶距离,单位为kwh/100km;平均油耗=行程行驶距离的油耗/行驶距离,单位为L/100km;也未采用改进的平均电耗和平均油耗的计算方法,即:将前一次充电之后,用车后期内的平均电耗和平均油耗,作为本次平均电耗和平均油耗的计算参数,拉低电池包和增程器共同驱动车辆行驶时的过高平均电耗和平均油耗。本申请实施例参考车辆的电量状态、车辆模式、当前行程的行驶距离来计算初始平均电耗和初始平均油耗,并且是在增程器启动完成之后,计算初始平均油耗,规避了平均电耗和平均油耗叠加的时段,而且还使用能耗基准值校准初始平均电耗和初始平均油耗,使得校准后的平均电耗和平均油耗之和更贴近增程汽车实际的百公里平均能耗。In the embodiment of the present application, after the range-extended vehicle is awakened, the vehicle mode and battery pack power of the range-extended 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-extended vehicle to travel, and the initial average power consumption corresponding to the range-extended vehicle is determined according to the calibrated average power consumption per unit mileage of the range-extended vehicle, the vehicle power parameters and the vehicle driving parameters; 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-extended vehicle to travel. to drive the extended-range 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, the initial average fuel consumption corresponding to the extended-range vehicle is determined according to the real-time fuel injection amount of the extended-range vehicle and the vehicle driving parameters; an energy consumption reference value is determined according to the calibrated average power consumption per unit mileage and the reference average power consumption corresponding to the extended-range vehicle when the range extender is started; and according to the energy consumption reference 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 method of average power consumption and average fuel consumption, that is, average power consumption = power consumption of the travel distance / travel distance, in kwh/100km; average fuel consumption = fuel consumption of the travel distance / travel distance, in L/100km; nor does it adopt the improved calculation method of average power consumption and average fuel consumption, that is, the average power consumption and average fuel consumption in the later period of the vehicle after the previous charge are used as the calculation parameters of the average power consumption and average fuel consumption this time, so as to reduce the excessive 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 initial average fuel consumption with reference to the vehicle's power status, vehicle mode, and the travel distance of the current trip, and calculates the initial average fuel consumption after the range extender is started, avoiding the period of superposition of the average power consumption and the average fuel consumption, and also uses the energy consumption reference value to calibrate the initial average power consumption and the initial average fuel consumption, so that the sum of the calibrated average power consumption and the average fuel consumption is closer to the actual average energy consumption per 100 kilometers of the extended-range vehicle.
进一步地,由于增程汽车在当前行程开始后,先纯电行驶,之后切换为增程器发电驱动车辆行驶,切换过程将导致整车平均电耗和平均油耗存在叠加的问题。本申请实施例针对这种问题在计算平均电耗和平均油耗时,考虑当前行程开始时车辆的电量状态、车辆模式、当前行程的行驶距离,结合不同车辆模式下增程器启停控制策略(增程器启动和关闭策略),进行平均电耗和平均油耗计算,保证计算的平均电耗和平均油耗之和贴合增量汽车真实百公里能耗状态,给与用户合理的参考值,避免引起用户误解。Furthermore, since the extended-range vehicle first runs on pure electricity after the current trip begins, and then switches to the range extender to generate electricity to drive the vehicle, the switching process will cause the average power consumption and average fuel consumption of the whole vehicle to overlap. In view of this problem, the embodiment of the present application considers the battery status of the vehicle at the beginning of the current trip, the vehicle mode, and the driving distance of the current trip when calculating the average power consumption and average fuel consumption, and combines the start-stop control strategy of the range extender under different vehicle modes (range extender start and shutdown strategy) to calculate the average power consumption and average fuel consumption, ensuring that the sum of the calculated average power consumption and average fuel consumption fits the actual energy consumption status of the incremental vehicle per 100 kilometers, giving users a reasonable reference value to avoid misunderstandings by users.
为了使本申请实施例更加清楚且便于理解,下面对本申请实施例进行进一步地描述。In order to make the embodiments of the present application clearer and easier to understand, the embodiments of the present application are further described below.
下面先对本申请实施例涉及的参数进行介绍:The following first introduces the parameters involved in the embodiments of the present application:
车辆电量参数包括:所述电池包的实时电压和实时电流。其中,实时电压和实时电流可以是在软件运行周期内每个采样周期采集的电压和电流。软件运行周期是指从增程汽车被唤醒到当前采样周期的起点形成的时间段。采样周期的长度可以根据需求而定。The vehicle power parameters include: the real-time voltage and real-time current of the battery pack. The real-time voltage and real-time current may be the voltage and current collected in each sampling cycle within the software operation cycle. The software operation cycle refers to the time period from when the extended-range vehicle is awakened to the starting point of the current sampling cycle. The length of the sampling cycle can be determined according to demand.
车辆行驶参数包括:所述增程汽车的实时车速以及预设的车辆初始已行驶距离。其中,实时车速可以是在软件运行周期内每个采样周期采集的车速。车辆初始已行驶距离为一个预设参数。车辆初始已行驶距离可以为经验值或者通过实验获得的值。该值不会很大,太大会造成车辆实际能耗很高时长期偏离实际值,太小将发挥不了拉平均计算的作用。车辆初始已行驶距离可以设置为5km-10km之间的值。The vehicle driving parameters include: the real-time speed of the extended-range vehicle and the preset initial distance traveled by the vehicle. Among them, the real-time speed can be the speed collected in each sampling period during the software operation cycle. The initial distance traveled by the vehicle is a preset parameter. The initial distance traveled by the vehicle can be an empirical value or a value obtained through experiments. This value will not be very large.

As shown in FIG2 , it is a flow chart of the steps of determining the initial average power consumption according to an embodiment of the present application.
步骤S210,根据所述电池包的实时电压和实时电流,积分计算所述增程汽车的真实消耗电量O;并且,根据所述增程汽车的实时车速,积分计算所述增程汽车的真实行驶里程P。其中,积分计算的时间区间为一个软件运行周期。Step S210, based on the real-time voltage and real-time current of the battery pack, the real power consumption O of the extended-range vehicle is calculated by integration; and based on the real-time speed of the extended-range vehicle, the real mileage P of the extended-range vehicle is calculated by integration. The time interval of the integration calculation is one software operation cycle.
步骤S220,采用拉平均计算方式,根据所述增程汽车的标定单位里程平均电耗M、所述车辆初始已行驶距离、所述真实消耗电量O和所述真实行驶里程P,计算所述增程汽车对应的第一候选平均电耗Q。Step S220, using an average calculation method, according to the calibrated average power consumption per unit mileage M of the extended-range vehicle, the initial traveled distance of the vehicle, the actual power consumption O and the actual travel mileage P, calculate the first candidate average power consumption Q corresponding to the extended-range vehicle.

第一候选平均电耗Q为采用拉平均算法计算出的值,能够反映一段时间内的电耗。第二候选平均电耗R为一个时间点的平均电耗,在不同时刻的变化不够平稳,时大时小,所以,本申请实施例选择Q和R中的最小值作为初始平均电耗,使得初始平均电耗在不同时刻能够保持相对平稳。The first candidate average power consumption Q is a value calculated using an average algorithm, which can reflect the power consumption over a period of time. The second candidate average power consumption R is the average power consumption at a time point, which changes not smoothly at different times, sometimes large and sometimes small.
