Detailed Description
Embodiments of the present invention 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 invention and should not be construed as limiting the invention.
The following describes a vehicle and a method and apparatus for adjusting the display power thereof according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for adjusting display power according to an embodiment of the application. As shown in fig. 1, the method for adjusting the display power according to the embodiment of the application includes the following steps:
S101: and determining whether to start electric quantity display adjustment according to the difference value between the actual electric quantity value at the current moment of the battery and the display electric quantity value at the last moment.
It should be noted that, under some special working conditions, the displayed electric quantity is easy to be different from the actual electric quantity, if the displayed electric quantity is regulated according to the change rule of the actual electric quantity, the situation that the displayed electric quantity is still electric is necessary, but the vehicle cannot continue to run is necessarily caused, if the actual electric quantity is directly displayed, the electric quantity is greatly changed, and the illusion that the driver generates a vehicle fault is easy to cause mental scars, and the driving experience is influenced.
Therefore, the application determines whether to start display adjustment by judging the difference value between the actual electric quantity value at the current moment of the battery and the display electric quantity value at the last moment.
S102: when the electric quantity display adjustment is started, a correction mode of the display electric quantity value is determined according to the change value of the actual electric quantity value in the first preset display period.
It should be understood that when the display adjustment is needed, if the user controls the vehicle to perform operations such as playing music and lighting only after powering on, in order to adjust the display power as soon as possible to be the same as the actual power, the power-down display is quickened in the display process, and an illusion of vehicle failure is also generated, so that mental scaring is caused, and driving experience is affected. Therefore, the correction mode of the display electric quantity value, such as the fast correction and the slow correction, needs to be determined according to the change value of the actual electric quantity in the display period.
S103: and determining a correction amount by using at least one of the display electric quantity value at the last moment, the actual electric quantity value at the current moment and the target electric quantity according to a correction mode of the display electric quantity value, and correcting the display electric quantity value by using the correction amount until the display electric quantity value is within an allowable display range of the target electric quantity when the actual electric quantity value is the target electric quantity value.
The target electric quantity may be an electric quantity value obtained according to a preset rule of system data, for example, the target electric quantity may be obtained according to a difference between an actual electric quantity and a display electric quantity, that is, the actual electric quantity is subtracted from the difference to obtain the target electric quantity.
Further, the correction amount may be used to correct the display electric quantity value, specifically, the display electric quantity value may be controlled to decrease by a value corresponding to the correction amount, so as to achieve the purpose of correcting the display electric quantity value, where the value corresponding to the correction amount may be different in different correction modes.
Therefore, according to the method for adjusting the display electric quantity, the display electric quantity can be corrected according to the working condition in a correction mode of the display electric quantity value, so that the display electric quantity is in an allowable display range when the actual electric quantity is the target electric quantity, the requirement of displaying the actual electric quantity for a user is met, and meanwhile, the user cannot generate illusion of vehicle abnormality.
As one possible embodiment, determining whether to start the power display adjustment according to a difference between an actual power value at a current time of the battery and a display power value at a previous time includes: and judging whether the difference is larger than a preset difference, if so, determining to start electric quantity display adjustment, if not, not starting electric quantity display adjustment, and directly displaying the actual electric quantity value at the current moment on the terminal.
According to the analysis, the electric quantity display adjustment is started only when the difference between the display electric quantity at the previous moment and the actual electric quantity at the current moment is larger than the preset difference value, and if no difference or the difference meets the normal rule between power failure and display, the electric quantity display can be performed according to the normal display rule without display adjustment.
Alternatively, the preset difference may be a preset display precision, where the preset display precision may be obtained according to an actual situation of the vehicle, for example, a preset display precision of 1%, 5%, 10% or the like is obtained according to a vehicle model, a preset display precision pre-stored in advance, or the like. That is, when the power loss is less than a preset display precision, the actual power value at the current moment is directly displayed without additional display adjustment. For example, when the display electric quantity is 90% and the preset display precision is 5%, if the actual electric quantity is 89%, the difference between the display electric quantity and the actual electric quantity is smaller than the preset display precision and cannot be displayed, and when the actual electric quantity is required to be changed to 85%, the display electric quantity is directly displayed without adjusting the display electric quantity at the previous moment.
As another possible embodiment, determining a correction mode of the display electric quantity value according to a change value of the actual electric quantity value in the first preset display period includes: judging whether the change value reaches the preset display precision or not; if yes, determining that the correction mode of the display electric quantity value is quick correction; if not, the display electric quantity value is determined to be corrected slowly.
That is, the correction mode is set according to the relation between the change value of the actual electric quantity in the first preset period and the preset display precision, that is, if the change value of the actual electric quantity in one first preset period is greater than the preset display precision, quick correction is needed to meet the correction requirement, and if the change value of the actual electric quantity in one first preset period is less than the preset display precision, the power failure is slower, and the correction can be performed by adopting slower correction.
The refresh rate of the electronic product, that is, the refresh rate of the screen displaying the electric quantity is fast, which is far greater than the power-off quantity of the power-consuming element in each refresh period, for example, the refresh rate of the display screen may be several milliseconds, and when the electric automobile runs at the highest speed, a display accuracy of power-off also requires several seconds, so, in order to accurately identify the power-off rate, a plurality of refresh periods may be used as a first preset display period.
As a possible embodiment, when the correction mode is a quick correction, correcting the display electric quantity value by using at least one of the display electric quantity at the previous time, the actual electric quantity at the current time and the target electric quantity, including: and in the second preset display period, taking the preset display precision as a first correction amount, and correcting the display electric quantity value by using the first correction amount.
The second preset period is smaller than or equal to the first preset period, that is, the time length of the second preset period is smaller than or equal to the time length of the first preset period.
That is, in the quick correction process, the display electric power value is controlled to decrease by the preset display accuracy in every second preset display period.
It should be understood that the second preset period may be selected according to the road condition of the vehicle, and when the vehicle is running on a highway in city, the vehicle will have a low-speed power consumption state such as a red light, and at this time, the displayed electric quantity may be corrected slowly when the vehicle speed is low (the power consumption is low), that is, the difference between the displayed electric quantity and the actual electric quantity is recovered, so that the second preset period may be set equal to the first preset period, and the displayed electric quantity may be changed along with the change value.
However, when the vehicle is on a highway for long distance driving, a high power consumption state may be continuously maintained, and at this time, if the second preset period is still set equal to the first preset period, the displayed electric quantity is changed along with the change value, the situation that the electric quantity is not balanced when the electric quantity is exhausted is easy to occur, for example, when the displayed electric quantity is 40% and the actual electric quantity is less than 30%, the vehicle is likely to go from the urban area of Beijing to the river north at a high speed, and the driving requirement cannot be satisfied easily.
Therefore, in some cases, the second preset period is required to be smaller than the first preset period, so that the displayed electric quantity is accelerated to track up the actual electric quantity, and a user can find the charging pile in time according to the displayed electric quantity.
As another possible embodiment, as shown in fig. 2, when the correction mode is a slow correction, the display electric quantity value is corrected by using at least one of the display electric quantity value at the previous time, the actual electric quantity value at the current time and the target electric quantity value, including
S201: the change rate of the actual electric quantity value is obtained in real time.
S202: and acquiring a target adjustment quantity between the display electric quantity value and the target electric quantity at the last moment.
S203: and acquiring a target power failure quantity between the actual power quantity value and the target power quantity at the current moment.
The display electric quantity value at the previous moment and the actual electric quantity value at the current moment are used for determining the electric quantity value when the electric quantity display adjustment is started.
S204: and acquiring a second correction amount according to the change rate, the target adjustment amount and the target power-down amount, and correcting the display electric quantity value by using the second correction amount.
That is, during the slow correction, the correction amount can be corrected according to the real-time change rate of the actual electric quantity, so that the correction process accords with the power consumption trend of the user, and the illusion of abnormal power consumption is avoided.
Optionally, according to the change rate, the target adjustment amount and the target power-off amount may be used to obtain the second correction amount: second correction amount = actual fuel cut [ rate of change × target adjustment amount/target fuel cut ].
In the driving of the electric vehicle, high power consumption and low power consumption can be alternately performed, for example, in a road in an urban area, high power consumption is caused by frequent start and stop, but low power consumption is caused when a long-time red light is used. Therefore, in order to further match the correction of the display power amount with the trend of the power consumption of the user, the quick correction and the slow correction need to be performed alternately.
As yet another possible embodiment, as shown in fig. 3, the method for adjusting the display power further includes:
s301: the identification correction mode is changed from quick correction to slow correction.
S302: and correcting the second correction amount by using the quick correction times to obtain a third correction amount.
S303: and correcting the display electric quantity value at the previous moment according to the third correction quantity.
That is, when the fast correction is changed to the slow correction, the current second correction amount of the slow correction needs to be corrected to increase the correction speed.
Alternatively, the second correction amount may be added, for example, the second correction amount is 0.2%, and the third correction amount is 0.4%. Further, the number of continuous fast corrections may be obtained during the fast correction, and the second correction amount may be superimposed according to the number of fast corrections during the subsequent slow correction, for example, when the number of fast corrections is 2, the second correction amount may be superimposed twice.
Alternatively, since the purpose of the correction of the second correction amount is to recover the correction amount that is not generated during the quick correction, the correction of the second correction amount may be performed only when the quick correction is shifted to the slow correction, and the correction of the second correction amount may not be performed again for the new first correction amount when the change rate of the actual electric quantity value changes during the slow correction.
For example, at a certain moment, the display electric quantity obtained at the previous moment is 80%, and when the current actual electric quantity is 70% and the preset display precision is 1%, the difference between the display electric quantity and the actual electric quantity is 10% and is far greater than 1% of the preset display precision, so that it is determined that the display adjustment needs to be started. And, according to the difference between the displayed electric quantity and the actual electric quantity by 10%, the target electric quantity for display adjustment is determined to be 60%, the target adjustment quantity is determined to be 20%, and the target power loss is determined to be 10%. The refresh frequency of the display of the vehicle is 1 second, and the first preset display period and the second display period are set to be 1s.
At the beginning of display adjustment, the actual electric quantity is powered down from 70%, the power down is 0.05% per second and is far smaller than 1% of the preset display precision, so that slow correction is needed, 20s is needed for determining that the actual power down is 69% according to the power down frequency of 0.05% per second, and an acquisition formula of the first correction amount adopted according to the embodiment of the application is as follows: 1% [ (1/20)/(80% -60%)/(70% -60%) ] =0.1%, and since 0.1% is smaller than the preset display accuracy and cannot be displayed, it is necessary to correct the display electric quantity when the correction amount accumulated reaches 1% after waiting for 10s, that is, 79% after 10s, 69.5% for the actual electric quantity, 78% for 20s, and 69% for the actual electric quantity.
Then the actual power is powered down from 69% at the speed of 0.5% of the power down per second, slow correction is still needed, 2s is needed for determining that the actual power down is 68% according to the power down frequency of 0.5% of the power down per second, and the first correction is calculated to be 1%, so that the power is 77% after 1s, the actual power is 68.5%, the power is 76% after 2s, and the actual power is 68%.
Then, the actual electric quantity drops from 68% to 67% at a speed of 1% per second, and the variation value in the first preset display period is the same as the preset display precision, and quick correction is required, and since the second preset display period is also 1s, the electric quantity is 75% after 1s, and the actual electric quantity is 67%.
The actual electric quantity is still used for 1s from 67% to 66%, the correction mode is the same as the previous one, the electric quantity is 74% after 1s, and the actual electric quantity is 66%.
When the actual electric quantity is 65% from the 66% change value, 40s is used, and the first correction amount is determined to be 0.05% according to the slow correction method, but since it was in the fast correction state before, the first correction amount needs to be corrected according to the fast correction, that is, the first correction amount is superimposed to obtain the second correction amount of 0.1%, and therefore, the electric quantity is sequentially 73%, 72%, 71%, 70% in the following 10s, 20s, 30s, and 40 s.
The actual electric power consumption was changed to 64% at 20s, and 0.1% was corrected every second by the slow correction method, and the display electric power was changed to 69% after 10s, and 68% after 20 s. The actual electric quantity is changed to 63% by 10s, 0.2% is corrected every second by adopting a slow correction mode, the electric quantity is displayed to 67% after 5s, and the electric quantity is displayed to 66% after 10 s.
The actual electric quantity is changed from 63% to 62% and used for 17s, the first correction quantity is calculated by a correction formula to be about 0.1%, and the display electric quantity is 65% according to the first correction quantity at 10s, but at 17s, the difference is less than 1 preset display precision, so that the processing is performed according to one preset display precision and the display precision is changed to 64%.
When the time taken for the actual electric quantity to change to 61% is 12 seconds, the first correction amount is about 0.2% at this time according to the slow correction step, so that the display electric quantity becomes 63% after 5 seconds, the display electric quantity becomes 62% after 10 seconds, and after 12 seconds, the difference is less than 1 preset display accuracy, so that the processing is performed according to one preset display accuracy, and the display electric quantity becomes 61%; at this time, the whole difference correction is completed, and the subsequent terminal directly displays the actual electric quantity value.
In summary, according to the method for adjusting the display electric quantity provided by the application, the display electric quantity can be corrected according to the working condition in a correction mode of the display electric quantity value, so that the display electric quantity is in an allowable display range when the actual electric quantity is the target electric quantity, the requirement of displaying the actual electric quantity for a user is ensured, and meanwhile, the illusion of vehicle abnormality cannot be caused for the user.
In order to realize the embodiment, the invention further provides a device for adjusting the display electric quantity.
