Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A vehicle driving range calculation method, apparatus, electronic device, and storage medium according to an embodiment of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a method for calculating a driving range of a vehicle according to an embodiment of the present disclosure.
As shown in fig. 1, the method comprises the steps of:
and 101, monitoring the corresponding driving energy consumption in each unit driving mileage during the driving process of the vehicle.
The execution subject of the present embodiment is a driving range calculation device that may be provided in a processor of a vehicle.
Wherein the size of each unit of the traveled mileage is determined based on the reference rolling mileage. As one possible implementation, the reference rolling mileage may be divided into the same plurality of unit mileage. For example, the reference rolling distance is 5 km, and the unit driving distance is 1 km.
Each unit mileage in the present embodiment may be the current unit mileage or each historical unit mileage before the current unit mileage.
In one embodiment of the application, the vehicle is monitored by taking the unit driving mileage as a monitoring unit in the driving process, and when the current driving mileage of the vehicle is monitored to be in accordance with the unit driving mileage, the current driving mileage is taken as the historical unit driving mileage, the driving mileage in the next unit driving mileage is continuously monitored, and the current unit driving mileage and the previous multiple historical unit driving miles can be obtained by continuously rolling forwards. As shown in fig. 2, fig. 2 is a schematic diagram illustrating the scrolling principle based on the present embodiment, and as shown in fig. 2, the reference scrolling mileage is S1The unit mileage is Δ S, and the current mileage within the unit mileage is dynamically increased, i.e., Δ Si，ΔSiIs 0- Δ S. As shown in FIG. 2, in the rolling mileage indicated by A, the unit mileage numbered 1-6 is the mileage that has been completed, i.e. the historical unit mileage, and the unit mileage numbered 7 is the current unit mileageThe monitored mileage in the previous unit mileage is Δ Si. With the operation of the vehicle, when the monitored mileage of the current unit mileage with the number of 7 is Δ S, the unit mileage indicated by the reference rolling mileage is rolled forward, that is, the rolling mileage indicated by a in fig. 2 is changed into the rolling mileage indicated by B, and similarly, the rolling mileage indicated by B is changed into the rolling mileage indicated by C, so that the rolling is forward, and the latest reference rolling mileage S is always obtained1And the influence of the recent driving condition and temperature factors on driving is fully considered, so that the driving range is accurately calculated.
Specifically, in the present embodiment, the driving energy consumption amount corresponding to each unit mileage is monitored by monitoring each unit mileage. The driving energy consumption is the energy consumed by the vehicle for driving the vehicle to run during the running process.
In this embodiment, as a possible implementation manner, for the driving energy consumption amount corresponding to the monitored unit driving mileage, the driving energy consumption amount corresponding to each unit driving mileage monitored in the driving process of the vehicle is stored by using a corresponding energy array, and the driving energy consumption amount can be stored in the memory before the vehicle is powered off and stored in the nonvolatile storage unit when the vehicle is powered off, for example, in EFFORM, so as to avoid data loss, and the driving energy consumption amount of the latest preset number can be stored in the energy array, that is, the data stored in the energy array is updated in a rolling manner along with the operation of the vehicle, so that the latest data of the preset number is always stored in the energy array, and the storage capacity is reduced at the same time. And when the vehicle is powered on again and the driving range needs to be calculated, in order to ensure the continuity of the calculation of the driving range, the residual driving range can be continuously calculated on the basis of the driving energy consumption stored before the last power-off.
The monitoring of the corresponding driving energy consumption within each unit of travel distance can be realized by the following two implementation modes.
As one possible implementation, the correspondence between the mileage and the driving energy consumption amount may be determined, and the driving energy consumption amount corresponding to each unit mileage of the vehicle may be determined based on the correspondence.
As another possible implementation manner, since a part of the energy consumed by the vehicle is used for air conditioning, the energy consumed by the air conditioning can be removed according to the total energy consumed by the vehicle within the driving range to obtain the energy consumed by the vehicle for driving, i.e. the driving energy consumption.
And 102, acquiring the driving energy consumption monitored in a plurality of historical driving mileage units which have been driven recently, and acquiring the driving energy consumption monitored in the current driving mileage unit.
In this embodiment, since the traveled mileage within the current unit traveled mileage is continuously increased along with the operation of the vehicle, the driving energy consumption monitored within the obtained current unit traveled mileage also changes in a rolling manner.
For example, the unit driving mileage is 1000 meters, and the driving energy consumption monitored in the current unit driving mileage may be the driving energy consumption corresponding to the driving of the vehicle by 100 meters in the unit driving mileage, or may be the driving energy consumption corresponding to the driving of the vehicle by continuing to 120 meters, 150 meters, 200 meters, and so on, which is not listed in the embodiment.
In this embodiment, by acquiring the driving energy consumption amounts monitored in a plurality of historical mileage traveled recently and the driving energy consumption amount monitored in the current mileage, and by acquiring the driving energy consumption amounts monitored in a certain mileage traveled before the current time, since the current time is changed forward on the time axis, the driving energy consumption amount in the mileage traveled recently is obtained by scrolling.
And 103, determining a first energy consumption rate of the vehicle according to the monitored driving energy consumption in the plurality of historical driving mileage units and the monitored driving energy consumption in the current driving mileage unit, wherein the first energy consumption rate is used for indicating a rolling average energy consumption rate for driving the vehicle to run during the running process of the vehicle.
In a possible implementation manner of the embodiment, a first energy consumption rate of the vehicle for driving is determined according to the monitored driving energy consumption in the plurality of historical driving miles and the monitored driving energy consumption in the current driving mileage, and it is achieved that the calculated first energy consumption rate is rolling-changed along with the operation of the vehicle, and indicates a first energy consumption rate of the vehicle in a preset rolling mileage before the current time of the vehicle, and the first energy consumption rate is rolling-changed along with the change of the operation condition of the vehicle.
And 104, determining the current driving range according to the first energy consumption rate of the vehicle.
In this embodiment, because the first energy consumption rate of the vehicle indicates a plurality of historical unit driving miles before the current time and the energy consumption rate for driving the vehicle to run within the current unit driving mileage, the influence of various working conditions is fully considered, the method can be used for determining the mileage over which the remaining energy of the vehicle can continue to run, namely the driving mileage, and the accuracy is improved.
In a possible implementation manner of the embodiment of the application, if the vehicle is an electric vehicle, the current remaining available energy of the battery of the vehicle can be acquired, and the Driving range is determined according to the ratio of the remaining available energy of the battery to the first energy consumption rate of the vehicle.
For example, the power battery of the vehicle currently corresponds to a battery with a remaining available energy EiTotal energy consumption rate of the vehicle is ECaveThe driving range is Ei/ECave。
In the vehicle driving range calculating method, during the driving process of the vehicle, the total energy consumption rate within the preset rolling range before the current time can indicate the average energy consumption rate under the future working condition, so that the driving energy consumption amounts within a plurality of recently-driven unit driving ranges are monitored on the basis of a rolling mode to determine the first energy consumption rate of the vehicle, wherein the first energy consumption amount is used for indicating the rolling average energy consumption rate for driving the vehicle to drive during the driving process of the vehicle to predict the current driving range.
In practical application, the vehicle air conditioner may be turned on during the running of the vehicle, and the vehicle air conditioner may consume energy when the vehicle air conditioner is turned on, so that when the vehicle air conditioner is in an on state, the energy consumption rate of the air conditioner needs to be calculated in the calculation of the total energy consumption rate of the vehicle, so as to improve the accuracy of the determination of the driving history. To this end, in one embodiment of the present application, as shown in fig. 3, the method comprises the steps of:
and 301, monitoring the corresponding driving energy consumption within each unit driving mileage during the driving process of the vehicle.
In this embodiment, because the air conditioner also consumes energy for cooling or heating the air conditioner when the air conditioner is turned on, and the use of the air conditioner is not obviously regular, and the energy consumed by the air conditioner may change greatly within a certain mileage range, in the running process of the vehicle, when the driving energy consumption of the vehicle within each unit running mileage is calculated, in order to avoid the irregular influence of the use of the air conditioner, the energy consumed by the air conditioner may be subtracted from the total energy consumed by the vehicle, so as to obtain the driving energy consumption consumed by the vehicle during the running process, thereby improving the accuracy.
The method for determining the driving energy consumption of the vehicle will be described in detail in the following embodiments.
The explanation in step 101 in the previous embodiment is also applicable to step 301 in this embodiment, and is not described herein again.
And step 303, determining a first energy consumption rate of the vehicle according to the monitored driving energy consumption in the plurality of historical driving mileage units and the monitored driving energy consumption in the current driving mileage unit, wherein the first energy consumption rate is used for indicating a rolling average energy consumption rate for driving the vehicle to run during the running process of the vehicle.
Specifically, step 302 and step 303 may refer to the descriptions in step 102 and step 103 in the previous embodiment, and the principle is the same, which is not described herein again.
And step 304, determining a second energy consumption rate in the state that the air conditioner is turned on, wherein the second energy consumption rate is used for indicating the rolling average energy consumption rate for driving the air conditioner to operate in the running process of the vehicle.
In this embodiment, when the air conditioner is turned on, the second energy consumption rate of the air conditioner is considered, and the second energy consumption rate is calculated according to the ambient temperature outside the vehicle, the target temperature inside the vehicle, and the vehicle speed indication information for indicating the vehicle running speed. That is to say, in the present application, the energy for driving and the energy for air conditioning are separated and calculated to obtain the first energy consumption rate and the second energy consumption rate, and then the sum of the first energy consumption rate and the second energy consumption rate is used as the total energy consumption rate of the vehicle, thereby improving the accuracy of determining the total energy consumption rate of the vehicle.
And step 306, determining the current driving range according to the total energy consumption rate.
In a possible implementation manner of the embodiment of the application, if the vehicle is an electric vehicle, the remaining available energy of the battery of the current vehicle is acquired, the ratio of the remaining available energy of the battery of the current vehicle to the total energy consumption rate of the vehicle is used for determining the driving range, and the influence of the driving condition and the ambient temperature is fully considered in the calculation process of the driving history, so that the accuracy of determining the remaining driving range is improved.
In the driving range calculating method of the present embodiment, a rolling average energy consumption rate for indicating driving of the vehicle during driving of the vehicle is calculated based on a rolling concept in a state where the air conditioner is turned on, i.e., the first energy consumption rate, and a rolling average energy consumption rate for driving the air conditioner to operate during the running of the vehicle, namely the second energy consumption rate, and simultaneously, in order to avoid the irregular influence of the energy consumption in the starting process of the air conditioner, the energy for driving the vehicle to run and the energy for driving the air conditioner to run are firstly separated to respectively calculate the first energy consumption rate and the second energy consumption rate, and the sum of the first energy consumption rate and the second energy consumption rate is used as the total energy consumption rate of the vehicle, the influence of the running working condition and the ambient temperature of the vehicle is fully considered, and the accuracy of determining the total energy consumption rate of the vehicle is improved.
In the above embodiment, how to determine the driving range based on the rolling concept is described, and in practical applications, when the vehicle is not in the D-range, and when the vehicle speed is smaller than the set vehicle speed, for example, when the vehicle is currently stopped, or when the vehicle speed is smaller than the set vehicle speed due to traffic jam in a city, the driving range error calculated by using the driving range determining method in the above embodiment is larger, because when the vehicle speed is smaller, the calculated rolling average vehicle speed is too low, and the second energy consumption rate is determined based on the rolling average vehicle speed, which may result in that the determined second energy consumption rate of the vehicle for air conditioning is too large and actually does not meet, so in an embodiment of the present application, before the step 304, the following steps are further included:
and determining that the gear operated by the vehicle is the D gear, and the speed of the vehicle operated by the vehicle is not less than the set speed.
According to the embodiment of the application, the accuracy of determining the total energy consumption rate of the vehicle is improved by determining that the gear of the vehicle is in a forward gear and the running speed of the vehicle is not less than the set speed.
Alternatively, when the vehicle is operated in a gear other than the D gear, for example, the park P gear, the reverse R gear, and the neutral N gear, the driving range is calculated based on the rolling average vehicle speed and the total energy consumption rate of the vehicle stored when the vehicle was recently in the D gear.
In the present application, in order to avoid the influence of the air-conditioning operation on the driving energy consumption of the vehicle and improve the accuracy of the driving energy consumption of the vehicle, the energy for driving the vehicle to run and the energy for driving the air-conditioning operation are separated to determine the driving energy consumption of the vehicle, and the method for determining the driving energy consumption of the vehicle is described below by using two embodiments.
In an embodiment of the present application, based on the above embodiment, fig. 4 is a third flowchart of a method for calculating a driving range of a vehicle according to the embodiment of the present application.
As shown in fig. 3, the above steps 101 and 301 include the following steps:
The power of the air conditioner, VCU can be obtained from the bus in real time. The remaining available energy of the battery can be obtained from the BMS.
It should be noted that the remaining available energy of the first battery and the remaining available energy of the second battery refer to the remaining available energy of the corresponding batteries within different unit driving mileage.
And step 402, removing the remaining available energy of the second battery from the remaining available energy of the first battery, removing the energy consumed by the air conditioner, and determining the corresponding driving energy consumption in the corresponding unit driving mileage.
For example, when the unit driving mileage i is full, the corresponding first battery remaining available energy is EiWhen the previous unit driving mileage i-1 of the unit driving mileage i is full, the corresponding remaining available energy of the second battery is Ei-1The power of the air conditioner is PAC(t), wherein the power of the air conditioner corresponds to the time t, that is, the power of the air conditioner may be different at different times within the unit driving range i.
Thus, the corresponding driving energy consumption amount Delta E within the corresponding unit mileageiCan be calculated by the following formula:
in the driving range calculation method of the embodiment, since the energy consumed by the power battery of the vehicle is mainly used for providing driving energy for the driving of the vehicle and the energy provided by the operation of the air conditioner, and since the energy consumed by the air conditioner in the driving process of the vehicle is large in change and has no fixed rule, when the driving energy consumption consumed by the actual driving of the vehicle in each unit driving range is monitored, the power in the operation of the air conditioner is obtained in real time, and the energy consumed by the air conditioner is removed from the energy consumed by the battery, so that the driving energy consumption used for driving of the vehicle is accurately determined, and the accuracy of determining the driving energy consumption is improved.
In another embodiment of the present application, based on the above embodiments, fig. 5 is a fourth flowchart of a vehicle driving range calculating method provided in the embodiment of the present application.
As shown in fig. 5, the above steps 101 and 301 include the following steps:
and step 501, acquiring air conditioner power, power battery direct-current bus voltage and direct-current bus current corresponding to each unit mileage.
Wherein the DC bus voltage and the DC bus current can be slave Battery Management systems (Battery Management Sys)tem, BMS), determining a corresponding driving energy consumption Δ E per unit driving mileage based on the air conditioning power, the dc bus voltage and the dc bus currentiSpecifically, the following formula can be used to implement:
In the driving range calculation method of the embodiment, since the energy consumed by the power battery of the vehicle is mainly used for providing driving energy for the driving of the vehicle and the energy provided by the operation of the air conditioner, and since the energy consumed by the air conditioner in the driving process of the vehicle is large in change and has no fixed rule, when the driving energy consumption consumed by the actual driving of the vehicle in each unit driving range is monitored, the power in the operation of the air conditioner is obtained in real time, and the energy consumed by the air conditioner is removed from the energy consumed by the battery, so that the driving energy consumption used for driving of the vehicle is accurately determined, and the accuracy of determining the driving energy consumption is improved.
In the above-described embodiments, it is described that the rolling average vehicle speed is determined according to the vehicle speed indication information corresponding to the plurality of unit traveled miles within the reference rolling mileage that has recently traveled, and the vehicle speed indication information may be the average vehicle speed corresponding to the unit traveled mileage or may be the accumulated travel time corresponding to the unit traveled mileage, and therefore, the following two embodiments are employed to describe the method of determining the rolling average vehicle speed based on different vehicle speed indication information.
Based on the foregoing embodiments, fig. 6 is a fifth flowchart of a method for calculating a driving range of a vehicle according to an embodiment of the present application, and illustrates how to determine a first energy consumption rate of the vehicle.
As shown in fig. 6, the step 103 includes the following steps:
Specifically, the mileage of the vehicle in the current unit of mileage is accumulated with the vehicle speed signal, and the mileage of the vehicle in the current unit of mileage is a dynamically changing process that gradually increases from 0 to the unit of mileage, for example, the unit of mileage is 1000 meters, and the vehicle mileage is from 0 meter to 1000 meters.
As a possible implementation manner, the actual rolling mileage may be determined according to the traveled mileage within the current unit traveled mileage, and the historical unit traveled mileage before the current unit traveled mileage is added to a preset number of historical unit traveled mileage, for example, the unit traveled mileage is Δ S kilometers, the historical traveled mileage refers to the completed unit traveled mileage, the size of the unit traveled mileage is the unit traveled mileage, the preset number is n, and the traveled mileage within the current unit traveled mileage is dynamically increased, i.e., the Δ S mileage is dynamically increasediThen the actual rolling distance S is equal to n × Δ S + Δ Si。
As another possible implementation, a reference rolling distance is determined, and a unit driving distance is determined according to the reference rolling distance, for example, the reference rolling distance is S1Dividing the reference rolling mileage into m parts, i.e., the unit driving mileage Δ S is S1The driving mileage within the current unit driving mileage is dynamically increased, namely delta SiWherein, Δ SiIs obtained by integrating the vehicle speed information acquired from an ELECTRONIC STABILITY CONTROL (ECS) system of the vehicle,
wherein t is the time of the vehicle in the unit driving mileage, the actual rolling mileage S is S ═ S1-ΔS+ΔSi。
Specifically, the driving energy consumption monitored in the unit driving mileage can be determined by referring to the explanation in the embodiment of fig. 4 and the embodiment of fig. 5, which is not described again in this embodiment.
In this example,. DELTA.EjFor driving energy consumption, Δ E, monitored in the jth historical mileageiThe driving energy consumption monitored in the current unit driving mileage.
First energy consumption Rate EC in the present embodimentdrvThe following formula can be adopted for implementation:
In the driving range calculation method according to the embodiment, the driving energy consumption of the historical unit driving range and the current unit driving range which are monitored are obtained according to the preset reference rolling range, and since the driving energy consumption of the recently-driven historical unit driving range and the driving energy consumption of the current unit driving range are always obtained based on the reference rolling range in the running process of the vehicle, the rolling-based idea is realized, and the first energy consumption rate corresponding to the recently-driven range is calculated.
Based on the foregoing embodiment, fig. 7 is a sixth schematic flowchart of a vehicle driving range calculating method provided in the embodiment of the present application, illustrating how to determine the determined second energy consumption rate consumed for driving the air conditioner to operate.
As shown in fig. 7, the step 304 includes the following steps:
For the idea of monitoring each unit driving mileage and the corresponding scrolling, reference may be made to step 101 in the embodiment of fig. 1, the principle is the same, and details are not described here.
The vehicle speed indication information may be an average vehicle speed corresponding to each unit mileage, or the vehicle speed indication information may be an accumulated travel time corresponding to each unit mileage.
In this embodiment, as a possible implementation manner, the vehicle speed indication information corresponding to the monitored unit mileage is stored by using a corresponding vehicle speed array, and the vehicle speed indication information corresponding to each unit mileage monitored in the vehicle driving process may be stored in the memory before the vehicle is powered off, and stored in the nonvolatile storage unit when the vehicle is powered off, for example, in EFFORM, so as to avoid data loss, and the vehicle speed indication information of the latest preset number may be stored in the vehicle speed array, that is, the data stored in the vehicle speed array is updated in a rolling manner along with the operation of the vehicle, so that the latest data of the preset number is always stored in the vehicle speed array, and the storage capacity is reduced at the same time. And when the vehicle is powered on again and the driving range needs to be calculated, in order to ensure the continuity of the calculation of the driving range, the remaining driving range can be continuously calculated according to the vehicle speed indication information stored before the last power off and the stored driving energy consumption.
In this embodiment, since the traveled mileage within the current unit traveled mileage is continuously increased along with the operation of the vehicle, the acquired vehicle speed indication information monitored within the current unit traveled mileage is also changed in a rolling manner.
For example, the unit driving distance is 1000 meters, and the monitored current unit driving distance may be vehicle speed indication information corresponding to the vehicle driving 100 meters in the unit driving distance, or vehicle speed indication information corresponding to the vehicle continuously driving 120 meters, 150 meters, 200 meters, and the like, which is not listed in the embodiment.
And 703, determining the rolling average vehicle speed according to the vehicle speed indication information monitored in the plurality of historical unit driving miles and the vehicle speed indication information monitored in the current unit driving mileage.
In the embodiment, the rolling average vehicle speed is determined according to the vehicle speed indication information monitored in the historical unit driving mileage and the vehicle speed indication information monitored in the current unit driving mileage, so that the rolling average vehicle speed obtained through calculation changes along with the running of the vehicle, the rolling average vehicle speed indicates the average vehicle speed of the vehicle in the preset rolling mileage before the current moment of the vehicle, and the rolling average vehicle speed changes along with the change of the running condition of the vehicle.
The specific calculation method of the rolling average vehicle speed will be described in the following embodiments.
In a possible implementation manner of this embodiment, the average power of the air conditioner of the vehicle in the on state is obtained, a plurality of ambient temperatures and target temperatures in the vehicle, which are collected based on a preset period, may be obtained, and the corresponding average power of the air conditioner of the vehicle is determined by looking up a table according to a correspondence between the average value of each ambient temperature and the target temperature in the vehicle and the average power of the air conditioner. Further, a second energy consumption rate is determined based on a ratio of the average power of the air conditioner to the rolling average vehicle speed. And furthermore, the total energy consumption rate of the vehicle is determined according to the sum of the second energy consumption rate and the first energy consumption rate, and the accuracy of determining the total energy consumption rate of the vehicle is improved due to the fact that the influence of the driving condition and the ambient temperature of the vehicle in the running process is fully considered.
Based on the foregoing embodiment, fig. 8 is a seventh schematic flowchart of a driving range calculating method provided in the embodiment of the present application, in which how to determine a rolling average vehicle speed of a vehicle is described in the present embodiment, where the vehicle speed indicating information is used to indicate a monitored average vehicle speed in a unit driving range.
In an embodiment of the present application, as shown in fig. 8, the step 703 includes the following steps:
Specifically, the mileage of the vehicle in the current unit of mileage is accumulated with the vehicle speed signal, and the mileage of the vehicle in the current unit of mileage is a dynamically changing process that gradually increases from 0 to the unit of mileage, for example, the unit of mileage is 1000 meters, and the vehicle mileage is from 0 meter to 1000 meters.
