Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Referring to fig. 1, fig. 1 is a flowchart of a method for determining a duration display value according to an embodiment of the present application.
As shown in fig. 1, the method for determining the duration display value includes the following steps:
step 101: calculating an average energy consumption value at the current moment according to a first energy consumption value, a second energy consumption value and a travel distance of the current stroke, wherein the first energy consumption value is a historical average energy consumption value, and the second energy consumption value is a preset distance average energy consumption value obtained at the current moment;
step 102: correcting the cruising correction basic value according to the vehicle state to obtain a cruising correction value, wherein the cruising correction basic value is a preset cruising adjustment amplitude corresponding to unit time;
step 103: determining a second cruising display value according to a first cruising display value, a cruising difference value and the cruising correction value, wherein the cruising difference value is a value obtained by subtracting a first cruising value from the first cruising display value, and the first cruising value is a cruising value calculated according to the available battery power and the average power consumption value at the current moment;
step 104: and updating the first continuous display value to the second continuous display value.
The method for determining the duration display value can be applied to an electric vehicle, and an execution subject of the method can be a device for determining the duration display value.
Prior to step 101, the endurance display value determining means may obtain a historical average energy consumption value, which may also be referred to as a historical total average energy consumption value, which may be equal to a ratio of the historical total energy consumption to the historical total mileage. The historical average energy consumption value typically varies little during the travel of a trip. Therefore, in order to simplify the calculation, in the embodiment of the present application, the historical average energy consumption value may be obtained at the start time of one trip, and the historical average energy consumption value may be used as the historical average energy consumption value during the driving of the one trip. That is, during the travel of one trip, the historical average energy consumption value does not need to be updated in real time.
Different from the historical average energy consumption value, the preset distance average energy consumption value and the distance travelled by the current journey are dynamic change values, and the preset distance average energy consumption value can be updated every time the vehicle travels for a fixed mileage (such as 0.1 km) or a fixed time (such as 1 s). In the driving process of one trip, the continuous voyage display value determining device can acquire a preset distance average energy consumption value and the driving distance of the current trip in real time. The preset distance average energy consumption value may be, for example, an average energy consumption value of 100km (i.e., 100 km).
In step 101, the cruising display value determining apparatus may calculate the average energy consumption value at the current time according to the first energy consumption value (i.e. the historical average energy consumption value), the second energy consumption value (i.e. the preset distance average energy consumption value obtained at the current time) and the distance travelled by the current trip. Because the preset distance average energy consumption value and the travel distance of the current travel are dynamic change values, the calculated average energy consumption value at the current moment can be adaptively and dynamically adjusted along with the change of driving working conditions, and compared with the historical average energy consumption value, the average energy consumption value at the current moment can reflect the real average energy consumption value.
After the average energy consumption value at the current moment is calculated, the continuous voyage display value determining device can calculate a first continuous voyage value according to the available battery quantity and the average energy consumption value at the current moment. The available battery power may be calculated based on a State of Charge (SOC) of the battery and a State of Health (SOH) of the battery. As an example, the battery usable power may be equal to the product of the full power, SOC and SOH, where SOC ranges from 0% to 100%, SOH ranges from 0% to 100%, and full power is the power of the battery at SOC of 100% and SOH of 100%. As an example, the first endurance value may be equal to a ratio of the available battery power to the average power consumption value at the current time.
As described above, compared with the historical average energy consumption value, the average energy consumption value at the current time can reflect the real average energy consumption value, so that the first cruising value calculated according to the available battery power and the average energy consumption value at the current time can reflect the real cruising value, and the accuracy is higher, and can be regarded as the real cruising value at the current time. The first endurance value calculated by the endurance display value determining device may fluctuate up and down due to higher accuracy, under the condition that the driving condition changes greatly. If the calculated duration value is directly output as the duration display value, the output duration display value may have a problem of up-down jump, resulting in poor user experience.
Based on this, the cruising display value determining apparatus does not directly use the calculated first cruising value as the cruising display value, but determines the cruising display value through steps 102 and 103.
In step 102, the device for determining a cruising display value may correct the cruising correction basic value according to the vehicle state to obtain a cruising correction value. Here, the duration correction basic value is a preset duration adjustment amplitude corresponding to a unit time, and may be understood as a maximum allowable duration adjustment amplitude in the unit time. Because the cruising correction basic value is corrected, the cruising adjustment amplitude in unit time is not too large, and the change of the cruising adjustment amplitude at different moments is relatively uniform, so that the cruising correction value obtained by correction can reduce the fluctuation degree of fluctuation of the actual correction value caused by the change of driving working conditions.
According to the vehicle state, the cruising correction basic value is corrected, which can be understood as: under different vehicle states, the cruising correction basic values are different, that is, the preset cruising adjustment ranges corresponding to unit time are different; or, in different vehicle states, the adopted correction modes (such as correction coefficients or correction factors or correction formulas) are different; or, the cruising correction basic value and the adopted correction mode are different in different vehicle states.
In step 103, the duration display value determining device may determine the second duration display value according to the first duration display value, the duration difference value, and the duration correction value. Here, the first duration display value is a currently displayed duration display value to be updated, and the second duration display value may be understood as an updated duration display value. The first duration display value may be understood as a duration display value determined and output at the previous time, and the second duration display value may be understood as a duration display value redetermined at the current time. Here, the time interval between the previous time and the current time may be understood as a preset unit time, for example, 1s, 3s, etc. Taking a preset unit time of 1s as an example, the continuous display value determining device needs to redetermine the continuous display value every 1s, and outputs the redetermined continuous display value to replace the continuous display value determined and output at the previous moment.
Before step 103, the duration display value determining device may calculate a duration difference value according to the first duration value and the first duration display value, specifically, subtract the first duration value from the first duration display value, where the obtained value is the duration difference value. As described above, the first endurance value has higher accuracy, which can be used as an actual endurance value, so that the endurance difference value calculated according to the first endurance value and the first endurance display value has higher accuracy, and can be used as an actual endurance difference value. However, if the calculated first duration value is directly output as the duration display value, the output duration display value may have a problem of up-down jump, in other words, the duration difference value at different moments may jump up-down. In step 103, the determined cruising display value is not simply based on the cruising difference value, but is determined by combining the cruising difference value and the cruising correction value, and the accuracy of the cruising difference value is higher, and the fluctuation degree of the actual correction value caused by the change of the driving working condition can be reduced by the cruising correction value, so that the determined cruising display value is higher in accuracy and smoother.
After determining the second duration display value, the duration display value determining device may update the first duration display value to the second duration display value.
As can be seen from the above process, the embodiments of the present application at least relate to the calculation of the following parameters:
calculating an average energy consumption value at the current moment;
calculating a first endurance value;
calculating a cruising correction value;
calculating a endurance difference value;
and calculating a second endurance display value.
The first cruising value is calculated according to the average energy consumption value at the current moment and the available electric quantity of the battery, the cruising difference value is calculated according to the first cruising display value and the first cruising value, and the second cruising display value is calculated according to the cruising correction value, the cruising difference value and the first cruising display value. Thus, the moment when the first endurance value and the endurance difference value are calculated may be any moment after the average energy consumption value at the current moment is calculated and before the second endurance display value is calculated, i.e. after step 101 and before step 103. As an example, the first endurance value may be calculated after the average energy consumption value at the current time is calculated.
In the embodiment of the application, the average energy consumption value at the current moment is calculated according to the historical average energy consumption value, the preset distance average energy consumption value obtained at the current moment and the travel distance of the current stroke. And correcting the cruising correction basic value according to the vehicle state to obtain a cruising correction value, and determining a second cruising display value according to the first cruising display value, the cruising difference value and the cruising correction value, wherein the cruising difference value is obtained by subtracting the first cruising value from the first cruising display value, and the first cruising value is a cruising value calculated according to the available electric quantity of the battery and the average energy consumption value at the current moment. In this embodiment of the present application, on the one hand, the parameter according to which the first endurance value is calculated is not just the historical average energy consumption, but the historical average energy consumption, the preset distance average energy consumption obtained at the current moment, and the current travel distance are combined, and since the preset distance average energy consumption and the current travel distance are dynamic change values, the preset distance average energy consumption can be adaptively and dynamically adjusted along with the change of the driving working condition, and therefore, even if there is a large change of the driving working condition, the accuracy of the calculated first endurance value is high, and the calculated first endurance value can be regarded as the actual endurance value at the current moment. On the other hand, as the cruising correction basic value is corrected according to the vehicle state, the cruising correction value obtained by correction fully considers the vehicle state, and the determined cruising display value is higher in accuracy and smoother. Through the embodiment of the application, the high-accuracy smooth endurance value can be output to the user, and even if the driving working condition has large change, the output endurance value can be prevented from frequent jump.
In some optional embodiments, the calculating the average energy consumption value at the current moment according to the first energy consumption value, the second energy consumption value and the distance travelled by the current trip includes:
calculating the average energy consumption value at the current moment according to the following formula:
wherein Q is t Represents the average energy consumption value at the current moment, Q Total (S) Represents a first energy consumption value, N represents a preset distance of N, Q N The second energy consumption value is represented, and a represents the distance travelled by the current trip.
In some optional embodiments, before the calculating the average energy consumption value at the current time according to the first energy consumption value, the second energy consumption value and the distance travelled by the current trip, the method further includes:
and acquiring the first energy consumption value corresponding to the user according to the login information of the current user.
In practical situations, driving habits of different users are different, when the different users drive the vehicle, certain differences exist in the historical average energy consumption values, and the preset distance average energy consumption values are different.
In this embodiment, considering that driving habits of different users are different, in order to eliminate an influence of the driving habits of the users on the accuracy of the range, the first energy consumption value in this embodiment of the present application may be a historical average energy consumption value corresponding to the current user. Specifically, the duration display value determining device may invoke, from the memory, the historical average energy consumption value of the user as the standard energy consumption to characterize the driving habit of the user according to the login information of the user (i.e., the current user). Therefore, the average energy consumption value at the current moment calculated based on the historical average energy consumption value corresponding to the user is more accurate, and the calculated first endurance value is more accurate.
In some optional embodiments, the determining the second duration display value according to the first duration display value, the duration difference value, and the duration correction value includes:
and determining a second continuous display value according to the first continuous display value and a continuous adjustment value, wherein the continuous adjustment value is the smaller value of the absolute value of the continuous difference value and the continuous correction value.
In this embodiment, the smaller value of the absolute value of the cruising difference value and the cruising correction value is used as the cruising adjustment value, so that the variation amplitude of the determined cruising display value and the first cruising display value is smaller, and therefore the cruising display values output at different moments are smoother, and the situation of up-down jump cannot occur.
When the driving condition of the vehicle changes greatly, and the vehicle has energy recovery capability, the endurance value calculated at different moments may fluctuate, and the endurance difference value may be a positive value or a negative value. When the duration value calculated at the current moment is smaller than the duration display value at the last moment, the duration difference value is a positive value (namely, the duration difference value is more than 0); when the duration value calculated at the current moment is larger than the duration display value at the previous moment, the duration difference value is a negative value (namely, the duration difference value is less than 0).
The following shows four ways of determining the second endurance display value:
case one: the duration difference value is larger than 0, the absolute value of the duration difference value is larger than the duration correction value, and the second duration display value=the first duration display value-the duration correction value;
and a second case: the duration difference value is more than 0, the absolute value of the duration difference value is less than or equal to the duration correction value, and the second duration display value=the first duration display value-the absolute value of the duration difference value;
and a third case: the duration difference value is less than 0, the absolute value of the duration difference value is greater than the duration correction value, and the second duration display value=the first duration display value+the duration correction value;
case four: and if the duration difference value is less than 0 and the absolute value of the duration difference value is less than or equal to the duration correction value, the second duration display value=the first duration display value+the absolute value of the duration difference value.
In some optional embodiments, the correcting the cruising correction basic value according to the vehicle state to obtain the cruising correction value includes:
and under the condition that the vehicle is in a running state, correcting the first cruising correction basic value according to at least one of a first influence coefficient, a second influence coefficient and a third influence coefficient to obtain a cruising correction value, wherein the first influence coefficient is an influence coefficient related to a cruising difference value, the second influence coefficient is an influence coefficient related to a vehicle speed, the third influence coefficient is an influence coefficient related to a battery parameter, and the first cruising correction basic value is a first preset cruising adjustment amplitude corresponding to the unit time.
In this embodiment, the first cruising correction base value may be understood as a maximum allowable cruising adjustment range per unit time in a running state of the vehicle.
This embodiment provides a correction method of the cruising correction value employed in the running state of the vehicle. In the running state of the vehicle, the driving conditions such as the running mileage, the vehicle speed, the battery state and the like are closely related, so that the running correction basic value can be corrected by combining the driving conditions such as the vehicle speed, the battery parameter and the like, wherein the second influence coefficient is the influence coefficient related to the vehicle speed, and the third influence coefficient is the influence coefficient related to the battery parameter. In addition, because there may be jump in the endurance difference, the endurance correction basic value may be corrected by combining the endurance difference, where the first influence coefficient is an influence coefficient related to the endurance difference.
The correction mode provided by the embodiment fully considers the influence factors of the jump of the continuous voyage value in the running state of the vehicle, so that the continuous voyage correction value obtained by correction can reduce the jump influence caused by the change of the driving working condition in the running state of the vehicle.
In some optional embodiments, the correcting the first cruising correction base value according to at least one of the first influence coefficient, the second influence coefficient and the third influence coefficient to obtain a cruising correction value includes:
Calculating a endurance correction value according to the following formula:
D＝D 1 ×(k 1 +k 2 +k 3 )
wherein D represents a cruising correction value, D 1 Represents a first endurance correction basic value, k 1 Representing a first influence coefficient, k 2 Representing a second influence coefficient, k 3 Representing a third influence coefficient, k 1 、k 2 And k 3 Are all greater than 0.
In this embodiment, when the vehicle is in a driving state, the first cruising correction basic value is corrected by combining the influence coefficients corresponding to the vehicle speed, the battery parameter and the cruising difference value, so as to obtain the cruising correction value, and three main influence factors which cause the cruising value to jump in the driving state of the vehicle are fully considered, so that the jump influence caused by the change of the driving working condition in the driving state of the vehicle can be reduced to a greater extent by the corrected cruising correction value.
Of course, the first cruising correction basic value may be corrected only according to the first influence coefficient, or the first cruising correction basic value may be corrected according to the first influence coefficient and the second influence coefficient, or the first cruising correction basic value may be corrected according to the first influence coefficient and the third influence coefficient, or the like, which is not limited in this embodiment of the present application.
Note that k 1 、k 2 And k 3 The values of (a) can be empirical values.
In some optional embodiments, the first influence coefficient is related to positive and negative of the endurance difference, where the first influence coefficient corresponding to the endurance difference is greater when the endurance difference is positive than the first influence coefficient corresponding to the endurance difference is negative;
the second influence coefficient is positively correlated with the vehicle speed;
the third influence coefficient is positively correlated with the SOC of the battery.
Wherein, the positive and negative of the endurance difference value is relative to the first influence coefficient,
from the perspective of a user, the rule that the continuous mileage is gradually reduced in the running state of the vehicle is more in line with the cognitive habit of the user. When the endurance difference is a positive value, the endurance mileage is gradually reduced, so that the cognitive habit of the user is better met, and when the endurance difference is a negative value, the endurance mileage is increased, so that the cognitive habit of the user is less met. Based on this, when the endurance difference is a positive value, the adjustment amplitude of the endurance display value may be moderately larger, and the endurance correction value may be moderately larger. When the duration difference is a negative value, the adjustment amplitude of the duration display value can be moderately smaller, and the duration correction value can be moderately smaller.
In a running state of the vehicle, the larger the vehicle speed is, the larger the range of the range is, and the smaller the vehicle speed is, the smaller the range of the range is. Therefore, the larger the vehicle speed is, the larger the second influence coefficient is, so that the larger the duration correction value is, and the larger the variation range of the duration display value is, so that the variation rule of the duration mileage is more met. The smaller the vehicle speed is, the smaller the second influence coefficient is, so that the smaller the duration correction value is, the smaller the variation range of the duration display value is, and the variation rule of the duration mileage is more met.
In a running state of the vehicle, for the same SOC variation range, the larger the SOC of the battery is, the larger the variation range of the range is, and the smaller the SOC of the battery is, the smaller the variation range of the range is. As an example, the SOC of the battery is changed from 90% to 80%, and the larger the range of change of the corresponding range of the battery is, the smaller the range of change of the corresponding range of the battery is, compared to the SOC of the battery is changed from 50% to 40%. Therefore, the larger the SOC of the battery is, the larger the third influence coefficient is, so that the larger the duration correction value is, and the larger the variation range of the duration display value is, so that the variation rule of the duration mileage is more met. The smaller the SOC of the battery is, the smaller the third influence coefficient is, so that the smaller the duration correction value is, the smaller the variation range of the duration display value is, and the change rule of the duration mileage is more met.
In this embodiment, by setting the influence coefficients as described above, the obtained cruising correction value more accords with the change rule of the cruising mileage, so that the determined cruising display value is more reasonable.
In some optional embodiments, the correcting the cruising correction basic value according to the vehicle state to obtain a cruising correction value further includes at least one of the following:
under the condition that the vehicle is in a charging state, correcting a second cruising correction basic value to obtain a cruising correction value, wherein the second cruising correction basic value is a second preset cruising adjustment amplitude corresponding to the unit time;
under the condition that the vehicle is in a stationary state, correcting a third cruising correction basic value to obtain a cruising correction value, wherein the third cruising correction basic value is a third preset cruising adjustment amplitude corresponding to the unit time;
the second continuous voyage correction basic value is larger than the first continuous voyage correction basic value, and the third continuous voyage correction basic value is smaller than the first continuous voyage correction basic value.
The embodiment further provides a correction mode of the continuous voyage correction value adopted by the vehicle in a charging state and a correction mode of the continuous voyage correction value adopted by the vehicle in a static state. A stationary state is understood to be a state of rest of the vehicle when in a non-charged state, as opposed to a charged state.
The vehicle is in a charging state, the electric quantity of the battery is gradually increased, and the vehicle basically does not need to consume electric energy at the moment, the continuous voyage mileage is gradually increased along with the increase of the electric quantity of the battery, and the change range of the continuous voyage mileage in unit time is larger, so that the second continuous voyage correction basic value can be larger than the first continuous voyage correction basic value. In addition, the vehicle has no change of driving conditions in the charging state, and the change amplitude of the endurance difference value at different moments is monotonically related to the change amplitude of the battery electric quantity, so that the change amplitude of the endurance difference value in the charging state is relatively stable.
As an example, when the vehicle is in a charged state, the second cruising correction basic value may be corrected by directly using the second cruising correction basic value as the cruising correction value, that is, the correction coefficient for correcting the second cruising correction basic value may be 1, i.e., d=d 2 Wherein D is 2 And the second endurance correction base value is represented.
In the stationary state of the vehicle, since the vehicle power consumption is small at this time, the range of change of the range per unit time is small, and therefore, the third range correction base value may be smaller than the first range correction base value. In addition, the vehicle has no change of driving conditions in a static state, so that the change range of the cruising difference value at different moments is stable.
As an example, when the vehicle is in a stationary state, the third cruising correction base value may be corrected by directly using the third cruising correction base value as the cruising correction value, that is, the correction coefficient for correcting the third cruising correction base value may be 1, that is, d=d 3 Wherein D is 3 And the third cruising correction basic value is represented.
It should be noted that the first cruising correction basic value, the second cruising correction basic value and the third cruising correction basic value may be empirical values.
In the embodiment of the application, under different vehicle states, different correction basic values and different correction modes are adopted for correction, so that the obtained cruising correction value is more reasonable, and the cruising display value determined under different vehicle states is more accurate and smoother.
The following illustrates the determination of the endurance display value in connection with a specific example.
After the user A unlocks the automobile, the calibrated energy consumption of the user is 15kWh/100km. In the running process, the average energy consumption value of the first 50km and the distance that the user has run the current journey can be obtained every unit time.
Assuming that the first 50km average energy consumption value is 20kWh/100km at a certain moment, and the user has traveled 25km on this trip, the current moment average energy consumption value=20×0.5+15×0.5=17.5 kWh/100km may be calculated.
Assuming that the SOC of the current battery is 50%, SOH is 90%, temperature is 10 ℃, and the estimated available power of the battery is 50kWh, a first cruising value=50++17.5= 285.72km may be calculated.
Assuming that the first cruising display value is 290km, a cruising difference value of 4.28km can be obtained.
Assuming that the corrected duration correction value is 0.5km, the duration difference value is greater than the duration correction value, so the duration correction value is taken as a duration adjustment value, and the determined second duration display value=290-0.5=289.5 km. At this time, 289.5km may be output to the user as the current range, e.g., 289.5km is displayed by a range meter of the vehicle.

In summary, in the embodiment of the application, by calculating the cruising value with higher accuracy, on the basis, processes such as cruising correction are adopted, so that the determined cruising display value is higher in accuracy and smoother. Through the embodiment of the application, the high-accuracy smooth endurance value can be output to the user, and even if the driving working condition has large change, the output endurance value can be prevented from frequent jump.
