Description
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for adjusting the driving range of an automobile.
Background
In the current automobile, the driving range can be displayed through a combination meter or a central control panel, the driving range is used for indicating how many driving ranges can be driven before the energy of the current automobile is exhausted, and the unit is generally Km or 0.1Km, so that the owner of the automobile is guided to supplement the energy before the energy is exhausted, or the owner of the automobile is indirectly informed whether the automobile can reach the required destination or not.
In the related art, the driving range is usually calculated according to the current energy remaining amount of the vehicle and the hundred kilometers of energy consumption of the vehicle. However, the driving range is calculated in the related art based on the fact that the energy is consumed smoothly or in a linear descending trend, otherwise, the driving range calculated by the remaining amount of the energy and the hundred kilometers of the vehicle has an error with the actual driving range of the vehicle. For example, in the case of a fuel-powered vehicle and a vehicle in which fuel and a power battery are mixed, since fuel is a fluid liquid, a fuel tank may shake during the driving of the vehicle, which may cause the collected fuel amount value to fluctuate, and the driving range calculated based on the collected fuel amount value may fluctuate, which may cause the driving range to fluctuate. For example, in the case of an electric vehicle, while the electric vehicle is traveling on an uphill or downhill road, the electric vehicle may have its SOC value of the power battery vertically shifted due to the uphill or downhill, and thus the electric range displayed on the corresponding electric vehicle meter may also vertically shift. Therefore, it can be seen that if the driving range in the meter is directly updated according to the calculated driving range, the driving range in the meter can shake up and down, which may cause the driver to feel data inaccurate enough and affect the user experience, and therefore, after the calculated driving range is obtained, how to reasonably adjust the driving range in the meter is very important for improving the user experience.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, 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 illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a method and an apparatus for adjusting the driving range of an automobile according to an embodiment of the present invention with reference to the drawings.
Fig. 1 is a flowchart of a method for adjusting a driving range of an automobile according to an embodiment of the present invention.
As shown in fig. 1, the method for adjusting the driving range of the automobile includes:
and S11, acquiring the initial driving range in the center control panel when the automobile is started.
Since the energy state of the vehicle before the vehicle is started may change, for example, the vehicle owner may fill the vehicle with oil, the fuel tank of the vehicle may leak, the vehicle owner may charge the vehicle, or the battery chemistry may cause a reduction in the amount of electricity, when the vehicle is started, the driving range of the vehicle may be recalculated according to the current state of the vehicle, and the initial driving range displayed in the center control panel when the vehicle is started may be updated according to the calculated driving range.
For the energy classification of the current automobile, the automobile can be classified into a fuel automobile, an electric automobile and a hybrid automobile (an automobile with a mixed fuel and a power battery), and the process of determining the initial driving range when the automobile is started by the fuel automobile, the electric automobile and the hybrid automobile is described below.
(1) For a fuel oil automobile, after the automobile is started, the current oil mass of the automobile can be obtained through a sensor of an oil tank, then the actual oil consumption of the automobile in hundred kilometers in the current automobile is obtained, and then the theoretical initial driving range of the automobile is calculated according to the obtained current oil mass and the actual oil consumption of the automobile in hundred kilometers in the current automobile, wherein the calculation formula is as follows:
and after the theoretical initial driving range is calculated, taking the theoretical initial driving range as the initial driving range in the central control panel when the automobile is started.
When the automobile is started for the first time, the initial driving range of the automobile can be calculated according to the hundred-kilometer ideal oil consumption of the automobile preset in the automobile and the current oil quantity of the automobile.
The hundred-kilometer ideal oil consumption of the vehicle is preset according to the type of the automobile, for example, the hundred-kilometer ideal oil consumption of the vehicle can be set to be 10L/100Km for a certain type of automobile.
(2) For an electric automobile, after the automobile is started, the current electric quantity of a power battery is obtained, the actual power consumption of the automobile in hundred kilometers at the current time is obtained, and the theoretical initial driving range of the automobile is calculated according to the current electric quantity and the actual power consumption of the automobile in hundred kilometers at the current time, wherein the calculation formula is as follows:
after the theoretical initial driving range is calculated, the theoretical initial driving range can be used as the initial driving range in the central control panel when the automobile is started.
(3) For a hybrid electric vehicle, the entire vehicle running mode of the hybrid electric vehicle is in a pure electric mode, and the process of determining the initial driving range is the same as that of the electric vehicle, and is not described herein again.
When the whole vehicle running mode of the hybrid electric vehicle is in a mixed mode, the theoretical initial oil driving range of the vehicle can be calculated according to the current oil quantity of the vehicle and the actual power consumption of the current vehicle for hundred kilometers, the theoretical initial electric driving range of the vehicle can be calculated according to the current electric quantity of the vehicle and the actual power consumption of the current vehicle for hundred kilometers, then the theoretical initial oil driving range and the theoretical initial electric driving range are summed to calculate the theoretical initial driving range of the vehicle, and the theoretical initial driving range is used as the initial driving range in the central control panel when the vehicle is started.
Since fuel is a liquid fluid substance, various vehicle conditions may occur during the use of the vehicle, and if the fuel in the fuel tank is in a shaking state, and at the time, the vehicle is repeatedly started and stalled, the fuel driving range calculated according to the fuel amount may vary from time to time, which may result in that the vehicle does not actually run, but the driving range varies from time to time when the vehicle is repeatedly started, so in an embodiment of the present invention, for a fuel-powered vehicle, before obtaining the initial driving range in the center control panel when the vehicle is started, the embodiment may further obtain the driving range before the vehicle is last closed, determine whether the absolute value of the difference between the theoretical initial driving range calculated when the vehicle is started and the driving range before the vehicle is last closed is greater than or equal to a third preset threshold, and if the absolute value is greater than or equal to the third preset threshold, and if not, taking the driving range before the last closing as the initial driving range of the automobile, and continuously displaying the driving range before the last closing in the central control panel, namely, if the absolute value of the difference value between the theoretical initial driving range calculated when judging that the automobile is started and the driving range before the last closing is smaller than a third preset threshold value, not updating the driving range in the central control panel according to the theoretical initial driving range, namely, continuously displaying the driving range before the last closing in the central control panel of the automobile.
Wherein the third preset threshold is calibrated in advance according to the actual emission of the automobile.
In one embodiment of the invention, when the vehicle is a hybrid vehicle and the entire vehicle running mode is a hybrid mode, before determining the initial driving range of the vehicle according to the current energy state of the vehicle, the theoretical oil driving range and the theoretical electric driving range at the time of starting the hybrid vehicle can be obtained, the oil driving range before the hybrid vehicle is closed last time can be obtained, and whether the absolute value of the difference between the theoretical oil driving range at the time of starting the hybrid vehicle and the oil driving range before the hybrid vehicle is closed last time is greater than or equal to a third preset threshold value or not can be judged.
If so, updating the oil driving range in the central control panel when the hybrid electric vehicle is started according to the theoretical oil driving range, and updating the initial driving range in the central control panel when the hybrid electric vehicle is started according to the theoretical oil driving range and the theoretical electric driving range.
And if not, controlling the central control panel of the hybrid electric vehicle to continuously display the oil driving range, and updating the initial driving range in the central control panel when the hybrid electric vehicle is started according to the theoretical electric driving range and the oil driving range.
And S12, acquiring the current energy surplus of the automobile and the actual energy consumption of the automobile for hundreds of kilometers currently in the driving process of the automobile.
It should be understood that, in the driving process of the automobile, the actual energy consumption of the automobile over hundred kilometers may change according to the driving condition and the road condition.
And S13, calculating the theoretical driving range of the automobile according to the current energy surplus and the current hundred kilometers of actual energy consumption of the automobile.
And S14, determining the mileage adjustment amount according to the theoretical driving range and the initial driving range.
Specifically, after the theoretical driving range and the initial driving range of the automobile are obtained, the range adjustment amount needs to be determined according to the theoretical driving range and the initial driving range, and the range adjustment amount can be determined in various ways, for example, as follows:
in the first mode, the difference value of the initial driving range minus the theoretical driving range can be calculated, and the range adjustment amount can be determined according to the difference value.
Specifically, after the difference value obtained by subtracting the theoretical driving range from the initial driving range is calculated, the range adjustment amount corresponding to the current difference value may be determined according to the correspondence relationship between the difference value and the range adjustment amount, which are stored in advance.
It should be noted that, in the corresponding relationship, the mileage adjustment amounts corresponding to the difference values larger than zero are all larger than 1km, and the mileage adjustment amounts corresponding to the difference values smaller than zero are all smaller than 1 km.
For example, if the difference between the theoretical driving range and the initial driving range is calculated to be 20, and the range adjustment amount corresponding to 20 stored in the preset relationship is assumed to be 0.6 km, the range adjustment amount corresponding to the difference 20 may be determined to be 0.6 km according to the corresponding relationship.
And secondly, comparing the theoretical driving range with the initial driving range, if the initial driving range is determined to be larger than the theoretical driving range according to the comparison result, acquiring a first range difference value obtained by subtracting the theoretical driving range from the initial driving range, and further judging whether the first range difference value is equal to or larger than a first preset threshold value.
And if the first mileage difference value is judged to be equal to or larger than a first preset threshold value, acquiring a first preset value, and taking the first preset value as the mileage adjustment amount.
The first preset value is a preset value in the automobile, and the first preset value is smaller than 1 kilometer.
And if the first mileage difference value is smaller than the first preset threshold value, acquiring a first formula for calculating the mileage adjustment amount, and calculating the mileage adjustment amount according to the theoretical driving mileage, the initial driving mileage and the first formula.
As an exemplary embodiment, the first formula is
Wherein x represents a mileage adjustment amount, TFRTD represents an initial driving range, NFRTD represents a theoretical driving range, and a represents a first preset threshold.
For example, assuming that the first preset threshold is 20, the first formula for calculating the mileage adjustment amount is
In addition, if it is determined that the theoretical driving range is greater than the initial driving range according to the comparison result, a second range difference value obtained by subtracting the initial driving range from the theoretical driving range is obtained, and it is further determined whether the second range difference value is equal to or greater than a second preset threshold value.
And the second preset threshold is greater than or equal to the first preset threshold.
And if the second mileage difference value is judged to be equal to or larger than a second preset threshold value, acquiring a second preset value, and taking the second preset value as the mileage adjustment amount.
The second preset value is a preset value in the automobile, and the second preset value is greater than 1 kilometer, for example, when the first preset threshold is 20, the second preset value is 1.4.
And if the second mileage difference value is smaller than the second preset threshold value, acquiring a second formula for calculating the mileage adjustment amount, and calculating the mileage adjustment amount according to the theoretical driving mileage, the initial driving mileage and the second formula.
As an exemplary embodiment, the first formula is:
wherein x represents a mileage adjustment amount, TFRTD represents an initial driving range, NFRTD represents a theoretical driving range, and a represents a second preset threshold.
For example, assuming that the second predetermined threshold is 20, the corresponding first formula is
And S15, reducing the initial driving range by a preset range when the total range of the automobile is increased by the range adjustment amount so as to obtain an updated driving range, and controlling the central control panel to display the updated driving range.
The preset mileage is a preset value in the automobile, and is greater than or equal to 1 kilometer.
For example, assuming that the mileage adjustment amount is 0.6 km and the preset mileage is 1km, when the total mileage of the automobile is increased by 0.6 km, the initial driving mileage is reduced by 1km, so that the driving mileage in the automobile central control panel is modified in this way, and thus, the driving mileage in the central control panel gradually approaches the real automobile condition in a continuous adjustment way, thereby avoiding the occurrence of a jitter condition caused by directly adjusting the driving mileage in the central control panel according to the calculated theoretical driving mileage, and improving the automobile experience of the user.
For another example, assuming that the mileage adjustment amount is 0.6 km and the preset mileage is 2 km, the initial driving range is reduced by 2 km every time the total mileage of the automobile is increased by 0.6 km, so as to modify the driving range in the center control panel of the automobile.
The method for adjusting the driving range of the automobile comprises the steps of determining the initial driving range of the automobile according to the current energy state of the automobile when the automobile is started, acquiring the current energy surplus of the automobile and the actual energy consumption of the current automobile for hundreds of kilometers in the driving process of the automobile, calculating the theoretical driving range of the automobile according to the current energy surplus and the actual energy consumption of the current automobile for hundreds of kilometers, determining the range adjustment amount according to the theoretical driving range and the initial driving range, reducing the initial driving range by the preset range when the total range of the automobile is increased by the range adjustment amount, acquiring the updated driving range, and controlling the central control panel to display the updated driving range. Therefore, the driving range in the central control panel is gradually close to the real vehicle condition in a continuous adjustment mode, the shaking condition caused by directly adjusting the driving range in the central control panel according to the calculated theoretical driving range is avoided, and the vehicle experience of a user is improved.
