Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.
The following describes a vehicle range calculation method, a device, an electronic apparatus, and a storage medium according to an embodiment of the present application with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a vehicle driving range calculation method according to an embodiment of the present application.
As shown in fig. 1, the method comprises the steps of:
step 101, during the running process of the vehicle, the corresponding driving energy consumption in each unit of running mileage is monitored.
The execution subject of the present embodiment is a range calculation device that may be provided in a processor of a vehicle.
Wherein the size of each unit driving mileage is determined according to 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 mileage is 5 km, and the unit driving mileage is 1 km.
Each unit driving distance in this embodiment may be a current unit driving distance, or may be each historical unit driving distance before the current unit driving distance.
In one embodiment of the application, the unit driving mileage is used as a monitoring unit for monitoring in the driving process of the vehicle, and each time the current driving mileage of the vehicle is monitored to be in accordance with the unit driving mileage, the current driving mileage is used as a historical unit driving mileage, the driving mileage in the next unit driving mileage is continuously monitored, and the current driving mileage and the previous multiple historical unit driving mileage can be obtained by continuously scrolling forward. As shown in fig. 2, fig. 2 is a schematic diagram showing the scrolling principle based on the present embodiment, as shown in fig. 2, wherein the reference scroll mileage is S 1 The unit driving mileage is delta S, and the driving mileage in the current unit driving mileage is dynamically increased, namely delta S i ，ΔS i The value of (2) is 0-delta S. As shown in FIG. 2, in the rolling mileage indicated by A, the unit mileage numbered 1-6 is the mileage already completed, namely the historical unit mileage, the unit mileage numbered 7 is the current unit mileage, and the monitored mileage in the current unit mileage is DeltaS i . When the monitored driving distance of the current unit driving distance with the number of 7 is delta S along with the running of the vehicle, the unit driving distance indicated by the reference rolling distance is rolled forwards, namely the rolling distance indicated by A in fig. 2 is changed into the rolling distance indicated by B, and similarly, the rolling distance indicated by B is changed into the rolling distance indicated by C, so that the rolling forwards is realized, and the latest reference rolling distance S is always acquired 1 The influence of the latest driving working condition and temperature factors on driving is fully considered, so that the driving range is accurately calculated.
Specifically, in this embodiment, the driving energy consumption corresponding to each unit driving distance is monitored by monitoring each unit driving distance. The driving energy consumption is the energy consumed by the vehicle to drive the vehicle during running.
In this embodiment, as a possible implementation manner, the driving energy consumption corresponding to the monitored unit driving mileage is stored by using a corresponding energy array, and the driving energy consumption corresponding to each unit driving mileage monitored during the driving process of the vehicle may be stored in a memory before the power-down of the vehicle, and stored in a nonvolatile storage unit, for example, in an EFFORM, when the power-down of the vehicle occurs, so that data loss is avoided, the driving energy consumption of the latest preset number may be stored in the energy array, that is, the data stored in the energy array is updated in a rolling manner along with the running of the vehicle, so that the latest data of the preset number is always stored in the energy array, and meanwhile, the storage capacity is reduced. And when the vehicle is electrified again and the driving range needs to be calculated, in order to ensure the continuity of the driving range calculation, the remaining 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 in each unit of driving mileage can be realized by the following two implementation modes.
As a possible implementation, a correspondence between the driving distance and the driving energy consumption may be determined, and based on the correspondence, a driving energy consumption corresponding to the vehicle in each unit driving distance may be determined.
As another possible implementation, since a part of the energy consumed by the vehicle is used for the air conditioner, the energy consumed by the air conditioner may be removed according to the total energy consumed by the vehicle during the driving range, to obtain the energy consumed by the vehicle for driving, i.e., the driving energy consumption.
Step 102, obtaining the monitored driving energy consumption in a plurality of historical unit driving mileage which have been recently driven, and obtaining the monitored driving energy consumption in the current unit driving mileage.
In this embodiment, since the mileage that has been travelled in the current unit mileage is increased with the running of the vehicle, the driving energy consumption that has been monitored in the current unit mileage is also changed in a rolling manner.
For example, the unit driving distance is 1000 meters, and the driving energy consumption corresponding to the vehicle driving 100 meters in the unit driving distance may be detected in the current unit driving distance, or the driving energy consumption corresponding to the vehicle driving 120 meters, 150 meters, 200 meters, or the like may be detected, which is not specifically shown in the embodiment.
In this embodiment, by acquiring the driving energy consumption monitored in a plurality of historical unit driving ranges that have been recently driven and the driving energy consumption monitored in the current unit driving range, by acquiring the driving energy consumption monitored in a certain driving range before the current time, since the current time is changed forward on the time axis, the driving energy consumption in the recently driven range is realized by rolling.
And step 103, determining a first energy consumption rate of the vehicle according to the monitored driving energy consumption in the plurality of historical unit driving mileage and the monitored driving energy consumption in the current unit driving mileage, wherein the first energy consumption rate is used for indicating a rolling average energy consumption rate for driving the vehicle to run in the running process of the vehicle.
In one possible implementation manner of the embodiment, according to the monitored driving energy consumption in the plurality of historical unit driving mileage and the monitored driving energy consumption in the current unit driving mileage, a first energy consumption rate of the vehicle for driving is determined, the calculated first energy consumption rate is changed along with the running of the vehicle, the first energy consumption rate of the vehicle in a preset rolling mileage before the current moment of the vehicle is indicated, and the first energy consumption rate is changed along with the running condition of the vehicle.
Step 104, determining the current driving range according to the first energy consumption rate of the vehicle.
In this embodiment, the first energy consumption rate of the vehicle indicates a plurality of historical unit driving mileage before the current moment and the energy consumption rate for driving the vehicle to travel in the current unit driving mileage, so that the influence of various working conditions is fully considered, the method can be used for determining the mileage that the remaining energy of the vehicle can continue to travel, namely the continuous driving mileage, and the accuracy is improved.
In one 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 obtained, 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 remaining available energy E i The total energy consumption rate of the vehicle is EC ave Range=e i /EC ave 。
In the vehicle driving distance calculation method of the embodiment of the application, in the vehicle driving process, the total energy consumption rate in the preset rolling distance before the current moment can indicate the average energy consumption rate under the future working condition, so that the driving energy consumption in a plurality of unit driving distances which are recently driven is monitored based on a rolling mode to determine the first energy consumption rate of the vehicle, wherein the first energy consumption rate is used for indicating the rolling average energy consumption rate which is used for driving the vehicle to drive in the vehicle driving process to predict the current driving distance.
In practical application, the vehicle air conditioner may be turned on during 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 when the total energy consumption rate of the vehicle is calculated, so as to improve the accuracy of determining the continuous running course. To this end, in one embodiment of the application, as shown in fig. 3, the method comprises the steps of:
Step 301, during the running of the vehicle, the corresponding driving energy consumption in each unit of running mileage is monitored.
In this embodiment, since the air conditioner also consumes energy for cooling or heating of the air conditioner in the on state, but the use of the air conditioner is not obviously regular, the energy consumed by the air conditioner may vary greatly within a certain mileage range, so in the process of driving the vehicle, 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 to obtain the driving energy consumed by the vehicle in the process of driving, 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 the present embodiment, and will not be repeated here.
Step 302, obtaining the monitored driving energy consumption in a plurality of historical unit driving mileage which have been recently driven, and obtaining the monitored driving energy consumption in the current unit driving mileage.
Step 303, determining a first energy consumption rate of the vehicle according to the monitored driving energy consumption amount in the plurality of historical unit driving mileage and the monitored driving energy consumption amount in the current unit driving mileage, wherein the first energy consumption amount is used for indicating a rolling average energy consumption rate for driving the vehicle to run in the running process of the vehicle.
Specifically, the steps 302 and 303 may refer to the descriptions in the steps 102 and 103 in the previous embodiment, and the principles are the same, which is not repeated here.
Step 304, determining a second energy consumption rate in a state that the air conditioner is on, wherein the second energy consumption rate is used for indicating a rolling average energy consumption rate for driving the air conditioner to operate in a vehicle driving process.
Step 305, determining a total energy consumption rate of the vehicle based on a sum of the first energy consumption rate and the second energy consumption rate of the vehicle.
In this embodiment, under the condition that the air conditioner is turned on, the second energy consumption rate of the air conditioner is considered, the second energy consumption rate is calculated according to the external environment temperature of the vehicle and the internal target temperature of the vehicle, and the vehicle speed indication information for indicating the running speed of the vehicle, and the second energy consumption rate for driving the air conditioner to run is determined in this way, so that the influence of the driving condition and the environment temperature of the vehicle in the running process is fully considered, and the accuracy is high. In other words, in the application, the energy for driving and the energy for the air conditioner are stripped and respectively 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, so that the accuracy of the determined total energy consumption rate of the vehicle is improved.
Step 306, determining the current driving range according to the total energy consumption rate.
In one 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 obtained, the ratio of the remaining available energy of the battery of the current vehicle to the total energy consumption rate of the vehicle is determined to determine the driving range, and the influence of the driving condition and the environmental 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 in the embodiment, in the state that the air conditioner is turned on, based on the idea of rolling, the rolling average energy consumption rate for indicating the running of the vehicle in the running process of the vehicle, namely the first energy consumption rate, and the rolling average energy consumption rate for indicating the running of the air conditioner in the running process of the vehicle, namely the second energy consumption rate, are calculated, meanwhile, in order to avoid irregular influence of energy consumption in the air conditioner turning on process, the energy for driving the vehicle and the energy for driving the running of the air conditioner are stripped, so that the first energy consumption rate and the second energy consumption rate are calculated respectively, 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, the influence of the running working condition and the environmental temperature of the vehicle is fully considered, and the accuracy of the determined total energy consumption rate of the vehicle is improved.
In the above embodiment, it is described how the range is determined based on the idea of rolling, and in practical application, when the vehicle is not in the forward gear D range and when the vehicle speed is smaller than the set vehicle speed, for example, the vehicle is currently in a stopped state or the vehicle speed due to traffic jam in a city is smaller, the range error calculated by the range determining method in the above embodiment is larger, because 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 results in that the determined second energy consumption rate of the vehicle for air conditioning is too large and is not consistent, therefore, in one embodiment of the present application, the above step 304 further includes the following steps:
and determining that the gear of the vehicle is the D gear, and the running speed of 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 the forward gear and simultaneously the running speed of the vehicle is not less than the set speed.
Alternatively, when the gear in which the vehicle is running is not the D gear, for example, the P gear in park, the R gear in reverse, and the N gear in neutral, the range is calculated based on the rolling average vehicle speed and the total energy consumption rate of the vehicle stored when the latest vehicle is in the D gear.
In order to avoid the influence of air-conditioning operation on the driving energy consumption of the vehicle and improve the accuracy of the driving energy consumption of the vehicle, the driving energy consumption of the vehicle is determined by stripping the energy for driving the vehicle to run and the energy for driving the air-conditioning operation, and the method for determining the driving energy consumption of the vehicle is described below through two embodiments.
In an embodiment of the present application, fig. 4 is a third flow chart of a vehicle range calculation method according to the embodiment of the present application based on the above embodiment.
As shown in fig. 3, the steps 101 and 301 include the following steps:
step 401, for each unit driving distance, acquiring the monitored energy remained and available in the first battery and the air conditioner consumed energy in the corresponding unit driving distance, and acquiring the second energy remained and available in the second battery corresponding to the previous unit driving distance in the corresponding unit driving distance.
The power of the air conditioner, VCU, can be obtained from the bus in real time. The remaining available energy of the battery may be obtained from the BMS.
The first battery remaining available energy and the second battery remaining available energy refer to corresponding battery remaining available energy in different unit driving ranges.
Step 402, removing the remaining energy of the first battery from the remaining energy of the second battery, and removing the energy consumed by the air conditioner, and determining the corresponding driving energy consumption in the corresponding unit driving range.
For example, when the unit driving distance i is full, the corresponding first battery residual available energy is E i When the previous unit driving mileage i-1 of the unit driving mileage i is full, the corresponding second battery residual available energy is E i-1 The power of the air conditioner is P AC And (t), wherein the power of the air conditioner corresponds to the time t, that is to say, the power of the air conditioner at different time can be different in the unit driving mileage i.
Thus, the corresponding driving energy consumption Δe in the corresponding unit driving range i The method can be calculated by the following formula:
according to the driving distance calculation method of the embodiment, energy consumed by the power battery of the vehicle is mainly used for providing driving energy for vehicle driving and energy provided by air conditioner operation, and the energy consumed by the air conditioner in the vehicle driving process is changed greatly and has no fixed rule, so that power during air conditioner operation is obtained in real time when the driving energy consumed by the vehicle actually driving is monitored in each unit driving distance, the driving energy consumed by the air conditioner is removed from the energy consumed by the battery, the driving energy consumed by the vehicle for driving is accurately determined, and the accuracy of determining the driving energy consumption is improved.
In another embodiment of the present application, fig. 5 is a flowchart of a vehicle driving range calculating method according to the embodiment of the present application based on the above embodiment.
As shown in fig. 5, the steps 101 and 301 include the following steps:
step 501, for each unit driving distance, acquiring air conditioning power, direct current bus voltage and direct current bus current corresponding to the corresponding unit driving distance.
Step 502, determining corresponding driving energy consumption in corresponding unit driving mileage according to the air-conditioning power, the direct-current bus voltage and the direct-current bus current.
Wherein the DC bus voltage and the DC bus current can be obtained from a battery management system (Battery Management System, BMS), and the corresponding driving energy consumption delta E in the corresponding unit driving mileage is determined according to the air conditioning power, the DC bus voltage and the DC bus current i Specifically, the following formula can be adopted to realize:
wherein U (t) is DC bus voltage, I (t) is DC bus current, and P AC And (t) is the power of the air conditioner at the moment t.
According to the driving distance calculation method of the embodiment, energy consumed by the power battery of the vehicle is mainly used for providing driving energy for vehicle driving and energy provided by air conditioner operation, and the energy consumed by the air conditioner in the vehicle driving process is changed greatly and has no fixed rule, so that power during air conditioner operation is obtained in real time when the driving energy consumed by the vehicle actually driving is monitored in each unit driving distance, the driving energy consumed by the air conditioner is removed from the energy consumed by the battery, the driving energy consumed by the vehicle for driving is accurately determined, and the accuracy of determining the driving energy consumption is improved.
In the above embodiments, it is described that the rolling average vehicle speed is determined based on the vehicle speed indication information corresponding to a plurality of unit vehicle mileage within the reference rolling mileage of the latest travel, and the vehicle speed indication information may be the average vehicle speed for indicating the unit vehicle mileage, or may be the accumulated travel time for indicating the unit vehicle mileage, and therefore, the following two embodiments are adopted to explain the method of determining the rolling average vehicle speed based on the different vehicle speed indication information.
Based on the above embodiments, fig. 6 is a flowchart of a vehicle range calculation method according to an embodiment of the present application, which illustrates how to determine a first energy consumption rate of a vehicle.
As shown in fig. 6, the step 103 includes the steps of:
step 601, determining an actual rolling mileage according to a plurality of historical unit driving mileage and the driving mileage in the current unit driving mileage.
Specifically, the travelled distance of the vehicle in the current unit mileage is obtained by accumulating the vehicle speed signal, and the travelled distance of the vehicle in the current unit mileage is a dynamic change process of gradually increasing from 0 to the unit mileage, for example, the unit mileage is 1000 meters, and the travelled distance of the vehicle is increased from 0 meters to 1000 meters.
As a possible implementation manner, the preset number of historical units before the current driving mileage can be added according to the driving mileage in the current unit driving mileageThe driving mileage is determined to be the actual rolling mileage, for example, the unit driving mileage is Δs kilometers, the history driving mileage refers to the completed unit driving mileage, the size is the unit driving mileage, the preset number is n, and the driving mileage in the current unit driving mileage is dynamically increased, namely Δs i The actual rolling mileage s=n×Δs+Δs i 。
As another possible implementation, a reference rolling mileage is determined, and a unit driving mileage is determined according to the reference rolling mileage, e.g., the reference rolling mileage is S 1 The reference rolling mileage is divided into m parts, i.e., unit mileage Δs=s 1 The mileage within the current unit mileage is dynamically increased, namely delta S i Wherein DeltaS i Is integrated based on vehicle speed information obtained from an electronic stability CONTROL system (ELECTRONIC STABILITY CONTROL, ECS) of the vehicle,where t is the time the vehicle is traveling in a unit travel distance, the actual rolling distance s=s 1 -ΔS+ΔS i 。
Step 602, determining the total energy consumption corresponding to the actual rolling mileage according to the monitored driving energy consumption in the plurality of historical unit driving mileage and the monitored driving energy consumption in the current unit driving mileage.
The driving energy consumption monitored in the unit driving range is determined, and the explanation in the embodiment of fig. 4 and the explanation in the embodiment of fig. 5 may be referred to specifically, which will not be repeated in this embodiment.
In the present embodiment, ΔE j For the drive energy consumption, ΔE, monitored in the j-th history unit of driving distance i The drive energy consumption which has been monitored in the current unit driving range.
Step 603, determining a first energy consumption rate according to the ratio of the total driving energy consumption amount and the actual rolling mileage.
First energy consumption rate EC in the present embodiment drv Can be realized by adopting the following formula：
Wherein j is the number of the corresponding historical unit driving mileage, the value of j is 1 to n-1, n is the total number of the unit driving mileage corresponding to the reference rolling mileage, and S is the actual rolling mileage.
In the driving distance calculation method of the embodiment, the driving energy consumption of the monitored historical unit driving distance and the current unit driving distance is obtained according to the preset reference rolling distance, and the driving energy consumption of the monitored historical unit driving distance and the current unit driving distance is always obtained based on the reference rolling distance in the running process of the vehicle, so that the idea based on rolling is realized, and the first energy consumption rate corresponding to the latest driving distance is calculated.
Based on the above embodiments, fig. 7 is a flowchart of a vehicle range calculation method according to an embodiment of the present application, which illustrates how to determine the second energy consumption rate of the driving air conditioner.
As shown in fig. 7, the step 304 includes the following steps:
in step 701, during the running process of the vehicle, corresponding vehicle speed indication information in each unit of running mileage is monitored.
The concept of each monitored unit driving distance and the corresponding rolling may refer to step 101 in the embodiment of fig. 1, and the principle is the same, which is not described herein.
The vehicle speed indication information may be an average vehicle speed corresponding to each unit of driving mileage, or the vehicle speed indication information may be an accumulated driving time corresponding to each unit of driving mileage.
In this embodiment, as a possible implementation manner, the vehicle speed indication information corresponding to the monitored unit driving mileage is stored by using a corresponding vehicle speed array, and the corresponding vehicle speed indication information can be stored in a memory before the vehicle is powered down and in a nonvolatile storage unit, for example, in an EFFORM, when the vehicle is powered down, so as to avoid data loss, and the vehicle speed array can store the latest preset number of vehicle speed indication information, that is, the data stored in the vehicle speed array is updated by rolling along with the running of the vehicle, so that the latest data of the preset number is always stored in the vehicle speed array, and meanwhile, the storage capacity is reduced. And when the vehicle is electrified 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 on the basis of the stored vehicle speed indication information before the last power-off and the stored driving energy consumption.
Step 702, obtaining vehicle speed indication information monitored in a plurality of historical unit driving mileage which are driven recently, and obtaining vehicle speed indication information which are monitored in the current unit driving mileage.
In this embodiment, since the distance travelled in the current unit distance is increased with the running of the vehicle, the obtained vehicle speed indication information monitored in the current unit distance is also changed in a rolling manner.
