[0028] To make the objectives, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the embodiments and the accompanying drawings.

[0029] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood as the common meanings understood by those with ordinary skills in the art to which the present application belongs. The terms "first", "second" and similar terms used in the embodiments of the present application do not represent any order, number or importance, but are only used to distinguish different components. The terms "include", "contain" and similar terms mean that the elements or objects before the terms encompass the elements or objects listed after the terms and their equivalents, and do not exclude other elements or objects. The terms "connect" or "connected" and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right" and the like only represent relative positional relationships, and when the absolute positions of the described objects change, the relative positional relationships can also change accordingly.

[0030] In the related art, the vehicle often involves switching between high and low energy consumption during operation. The switching between high and low energy consumption can be caused by driving mode switching, such as switching from energy-saving mode to sports mode, which is switching from low-power mode to high-power mode. It can also be caused by changes in auxiliary energy consumption or driving behavior in the same driving mode, for example, turning on the air conditioner, frequent braking, or intense driving behavior, which can cause energy consumption to increase. When the vehicle switches between high and low energy consumption conditions, the vehicle's range will also be affected. The range is generally calculated by dividing the available energy by the historical average energy consumption in the current driving mode. For a fuel vehicle, the available energy is the remaining fuel quantity. For a pure electric vehicle, the available energy is the remaining electric quantity. For a hybrid vehicle, the available energy is the sum of the remaining fuel quantity and the remaining electric quantity. The historical average energy consumption in the current driving mode can be the average energy consumption in the current driving mode in the vehicle's historical data. When the available energy is constant, the historical average energy consumption in the current driving mode increases, and the range decreases. Conversely, the historical average energy consumption in the current driving mode decreases, and the range increases. Specifically, when switching from high energy consumption to low energy consumption, the range increases, and when switching from low energy consumption to high energy consumption, the range decreases. The vehicle's range is displayed on the instrument panel, which is also referred to as the displayed range. The displayed range will change due to changes in the historical average energy consumption in the current driving mode. However, the historical average energy consumption in the current driving mode does not reflect the current energy consumption level of the vehicle, for example, intense driving behavior in the current driving mode. Therefore, there is a significant discrepancy between the actual driving range and the displayed range. For example, in energy-saving mode, the displayed range is 300 km, but due to intense driving behavior, the actual driving range is only 150 km. Users will be confused and doubt the authenticity of the range and even experience range anxiety, affecting the user's driving experience.

[0031] In addition, according to the above calculation method of the range, if only driving mode switching is involved, the displayed range can instantaneously change significantly due to the difference in historical average energy consumption between the previous and subsequent driving modes. For example, after switching the driving mode from energy-saving mode to sports mode, the displayed range drops from 300 km to 250 km instantaneously. When the displayed range instantaneously changes, users will also experience range anxiety, affecting the user's driving experience.

[0032] Based on the above situation, there are mainly two reasons for the user to cause range anxiety: (1) the apparent range change (mainly based on the change of attenuation) does not match the actual range; (2) the apparent range changes greatly. This also reflects at least two problems: (1) the user does not have a clear understanding of the energy consumption change and the range change caused by his one-time or short-term operation behavior; (2) the calculation method of the apparent range needs to be further improved. If the above two problems can be solved, the user's range anxiety can be greatly reduced.

[0033] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0034] As shown in FIG. 1, a range display method is executed by a car machine controller, comprising:

[0035] S101, in response to monitoring the energy consumption switching signal, obtaining the energy consumption difference before and after the energy consumption switching;

[0036] The energy consumption switching signal is triggered based on the following switching actions, including but not limited to at least one of the following: switching of driving mode, switching of driving behavior, switching of auxiliary component opening state, etc. The switching of driving mode includes switching between energy saving mode and sports mode, or switching between ordinary mode and sports mode, etc. The switching of driving behavior includes switching between ordinary driving behavior and intense driving behavior, wherein the intense driving behavior is the driving behavior of sudden acceleration or sudden deceleration, and the ordinary driving behavior and the intense driving behavior of sudden acceleration or sudden deceleration can be judged by the opening degree of the brake pedal or the accelerator pedal and the time length in the opening degree, for example, the opening degree of the accelerator pedal exists in the state of the sudden acceleration opening degree threshold, and the state lasts for a duration of the preset duration, then it is considered that there is a sudden acceleration of the intense driving behavior; for example, the opening degree of the brake pedal exists in the state of the sudden deceleration opening degree threshold, and the state lasts for a duration of the preset duration, then it is considered that there is a sudden deceleration of the intense driving behavior. The switching of auxiliary component opening state includes switching of air conditioning state between opening and non-opening, etc.

[0037] It should be noted that the existence of energy consumption switching does not necessarily cause a large change in range, for example, the switching between ordinary mode and energy saving mode does not cause a large change in apparent range, because the energy consumption does not change much before and after the switching. Therefore, it is further necessary to judge the energy consumption difference before and after the energy consumption switching in this step, in order to prepare for whether to switch the display interface of the range of the instrument panel.

[0038] In addition, the determination manner of the energy consumption difference before and after the energy consumption switching in the step can be calculated by obtaining the vehicle energy consumptions before and after the energy consumption switching. For example, the energy consumption switching is the switching from the energy saving mode to the sports mode, the vehicle energy consumption at the last moment of the energy saving mode and the vehicle energy consumption at the first moment of the sports mode are obtained, the two energy consumptions are subtracted, and the difference is the energy consumption difference.

[0039] S102, in response to determining that the energy consumption difference is greater than the preset value, switching the current range display interface to the target display interface to display the change trend of the range by the target display interface.

[0040] In the step, when the energy consumption difference before and after the energy consumption switching is large (for example, the difference is greater than 10%), the current range display interface needs to be switched to the target display interface, and the target display interface is controlled to display the change trend of the range. The change trend can be static display or animation display. The user can intuitively see the influence of the current driving mode or driving behavior on the dynamic range of the vehicle through the target display interface, enhance the user's confidence in the range accuracy of the vehicle, and make the user have a clearer understanding of the dynamic range capability of the vehicle.

[0041] That is, when there is an energy consumption switching behavior, and the energy consumption difference before and after the energy consumption switching is large, the change trend of the range is displayed on the instrument panel. For example, the change trend display form can be as shown in FIG. 6, that is, the range before the energy consumption switching is 300 km, and the range after the energy consumption switching is 250 km. Before the energy consumption switching, the range display interface of the instrument panel displays 300 km, and after the energy consumption switching, the range display interface of the instrument panel displays 300 km→250 km. For another example, the change trend display form can be as shown in FIG. 7. Before the energy consumption switching, the range display interface of the instrument panel displays 300 km, and after the energy consumption switching, the range display interface of the instrument panel displays 300 km↓. That is, by displaying the change trend of the range by the target display interface, the user has a clearer understanding of the dynamic range capability of the vehicle, and avoids the range anxiety caused by the fact that the apparent range attenuation does not match the actual driving range or the apparent range changes instantaneously in the prior art.

[0042] It should be noted that the vehicle instrument panel generally displays a speedometer, a speedometer, an oil gauge, a water temperature gauge, and a range, etc. The range display interface and the target display interface mentioned in the application can be the display interface of the entire instrument panel, or can be only the area interface for displaying the range.

[0043] In the embodiment, when the energy consumption switching signal is monitored, it indicates that there is a risk of sharp change in the vehicle's range. By obtaining the size of the energy consumption difference before and after the energy consumption switching, the risk of sharp change in the range is determined. When the energy consumption difference before and after the energy consumption switching is large, it indicates that the risk of sharp change in the vehicle's range is high, and the current range display interface is switched to the target display interface to display the change trend of the range through the target display interface. The form of displaying the change trend of the range through the target display interface enables the user to have a more intuitive understanding of the influence of the current energy consumption switching on the range, and a clearer cognition of the dynamic range of the vehicle, avoiding the situation that the apparent range attenuation does not match the actual driving range or the apparent range changes instantaneously in the prior art, which causes the user's range anxiety.

[0044] Although the above embodiment can solve the problem of range anxiety caused by sharp change in the range during high-low energy consumption switching in the prior art, how to ensure the stability and accuracy of the obtained energy consumption difference, and how the apparent range changes and how the target display interface displays are still to be solved.

[0045] Based on the above problems, in some embodiments, as shown in FIG. 2, the energy consumption difference before and after the energy consumption switching in S101 includes:

[0046] S201, obtaining a first energy consumption and a second energy consumption at the current time;

[0047] The first energy consumption is the energy consumption level at a first time length from the current time, and the second energy consumption is used to reflect the energy consumption level at a second time length from the current time, and the second time length is greater than the first time length. The first time length and the second time length are only a relative concept. In other words, the first energy consumption is used to reflect the recent energy consumption (such as 3s from the current time), and the second energy consumption is used to reflect the relatively long-term energy consumption (such as 10s from the current time). In this application, the first energy consumption can also be referred to as short-term historical energy consumption, and the second energy consumption can also be referred to as long-term historical energy consumption. That is, the first energy consumption at the current time can reflect the energy consumption level after the energy consumption switching, and the second energy consumption at the current time can reflect the energy consumption level before the energy consumption switching.

[0048] S202, calculating the energy consumption difference before and after the energy consumption switching based on the first energy consumption and the second energy consumption at the current time.

[0049] The calculation process of the first energy consumption at the current time is as follows:

[0050] Obtaining the first energy consumption at the previous time and the vehicle energy consumption at the current time;

[0051] The first energy consumption at the previous time and the vehicle energy consumption at the current time are weighted according to the preset first weighting rule to obtain the first energy consumption at the current time;

[0052] The weight ratio given to the vehicle energy consumption at the current moment in the first weighting rule is greater than the weight ratio given to the first energy consumption at the last moment.

[0053] The second energy consumption at the current moment is calculated as follows:

[0054] The second energy consumption at the last moment and the vehicle energy consumption at the current moment are obtained.

[0055] The second energy consumption at the current moment is obtained by weighting the second energy consumption at the last moment and the vehicle energy consumption at the current moment according to a preset second weighting rule.

[0056] The weight ratio given to the vehicle energy consumption at the current moment in the second weighting rule is smaller than the weight ratio given to the second energy consumption at the last moment.

[0057] The vehicle energy consumption at the current moment mainly includes instantaneous driving energy consumption and instantaneous auxiliary energy consumption, wherein the instantaneous driving energy consumption can be calculated from the instantaneous driving power, and the instantaneous auxiliary energy consumption can be calculated from the instantaneous auxiliary power (including DCDC power and A / C power).

[0058] In the first energy consumption calculation process at the current moment, the weight ratio given to the vehicle energy consumption at the current moment is higher, for example, the weight ratio given to the first energy consumption at the last moment is 20%, and the weight ratio given to the vehicle energy consumption at the current moment is 80%, so that the updating speed of the self-learning process of the first energy consumption is faster, and it can better reflect the short-term historical energy consumption level of the vehicle.

[0059] In addition, in the second energy consumption calculation process at the current moment, the weight ratio given to the vehicle energy consumption at the current moment is smaller, for example, the weight ratio given to the second energy consumption at the last moment is 70%, and the weight ratio given to the vehicle energy consumption at the current moment is 30%, so that the updating speed of the self-learning process of the second energy consumption is slower than that of the first energy consumption, and it can better reflect the long-term historical energy consumption level of the vehicle.

[0060] The first energy consumption and the second energy consumption calculation process is the self-learning process of the calculation module of the vehicle machine controller or the calculation module of the cloud server, which starts to calculate when the vehicle is powered on and reaches a preset speed (such as 1 km / h), and ends when the vehicle is powered off. It can be directly obtained when needed.

[0061] It should be noted that in the self-learning process, when the first moment of calculating the first energy consumption in the current driving scenario, the first energy consumption at the last moment in the current driving scenario in the vehicle historical data is taken as the first energy consumption at the last moment; wherein the current driving scenario is the scenario between the current energy consumption switching and the next energy consumption switching or the last moment.

[0062] Since the first energy consumption is in response to the short-term historical energy consumption level of the vehicle, the accuracy requirement is higher. If the first energy consumption at the last moment of the driving scene before the energy consumption switching is directly selected as the first energy consumption at the last moment, it will inevitably lead to deviation in the calculation of the first energy consumption at the first moment of the current driving scene, which will directly affect the difference calculation of the first energy consumption and the second energy consumption, thereby affecting the switching between the range display interface and the target display interface, and affecting the user's driving experience. Therefore, in the embodiment, the first energy consumption at the last moment of the current driving scene in the vehicle historical data is selected as the first energy consumption at the last moment. Since the difference between the first energy consumption of two same driving scenes is smaller than the difference between the first energy consumption of the driving scenes before and after the energy consumption switching, the calculation error of the first energy consumption can be effectively reduced. It is explained that the switching of the driving scene in the application is based on the energy consumption switching, and the driving scene before the energy consumption switching is referred to as a driving scene, and the driving scene after the energy consumption switching is referred to as another driving scene. It should be noted that when the vehicle historical data is called, whether the driving scene is fused with multiple energy consumption switches needs to be considered. For example, the driving scene only involves the sports mode, and the first energy consumption at the last moment of the vehicle historical data only involving the sports mode needs to be called. For example, the current driving scene is in the sports mode and superimposed with the intensive driving behavior, and the first energy consumption at the last moment of the driving scene in the vehicle historical data after superimposing the sports mode and the intensive driving behavior needs to be called. Thus, the accuracy of the first energy consumption calculation is ensured.

[0063] Unlike the self-learning process of the first energy consumption, the calculation process of the second energy consumption does not consider the transformation of the driving scene, in other words, it does not consider the switching of high and low energy consumption. In the self-learning process, the first energy consumption at the last moment of the vehicle historical data is used as the second energy consumption at the last moment when the first moment of the second energy consumption is calculated. For example, the vehicle is powered on and the running speed reaches the preset speed, and the self-learning of the second energy consumption starts. When the first moment of the second energy consumption is calculated, the first energy consumption at the last moment of the vehicle historical data closest to the current driving can be used as the second energy consumption at the last moment. Compared with using the second energy consumption at the last moment of the vehicle historical data closest to the current driving as the second energy consumption at the last moment, the accuracy of the data calculation can be improved on the premise of ensuring the stability of the second energy consumption calculation.

[0064] It should be noted that after a vehicle trip ends, such as when the vehicle is powered off, the first energy consumption at the last moment of each driving scene in the trip will be stored in an EEPROM (Electrically Erasable Programmable read only memory) for subsequent reading and calling of the first energy consumption self-learning process, and the first energy consumption at the last moment of the trip will be reset to the second energy consumption and also stored in the EEPROM for subsequent reading and calling of the second energy consumption self-learning process. That is, the second energy consumption self-learning process reads the nominal second energy consumption in the vehicle historical data, which is actually the first energy consumption after reset.

[0065] In this embodiment, the first energy consumption and the second energy consumption are both used to reflect the energy consumption level within a certain period of time. The first energy consumption self-learning process has a faster update speed, which can better reflect the short-term historical energy consumption level of the vehicle. The second energy consumption self-learning process has a slower update speed than the first energy consumption self-learning process, which can better reflect the long-term historical energy consumption level of the vehicle. Thus, the data stability is better than directly obtaining the vehicle energy consumption at a certain moment, and the data accuracy is better than directly obtaining the average energy consumption within a certain period of time because it is based on different weight rules and is constantly iteratively updated.

[0066] As an alternative to the first energy consumption and the second energy consumption obtaining process, in some embodiments, the first energy consumption and the second energy consumption at the current moment are obtained, including:

[0067] The average energy consumption within a first period of time (e.g., 5s) from the current moment is obtained as the first energy consumption, and the average energy consumption within a second period of time (e.g., 10s) from the current moment is obtained as the second energy consumption.

[0068] The calculation process of the first energy consumption and the second energy consumption does not involve the self-learning process, although the accuracy is not as good as the first energy consumption and the second energy consumption obtained by the self-learning process described above, but the calculation process is simpler and more convenient, which is beneficial to quickly determine the energy consumption difference and perform subsequent steps.

[0069] The above embodiments solve the problem of how to ensure the stability and accuracy of the obtained energy consumption difference, but how the indicated range changes and how the target display interface is reasonably displayed still need to be solved.

[0070] To solve the above problem, in some embodiments, as shown in FIG. 3, the current range display interface is switched to the target display interface in S102 to display the change trend of the range through the target display interface, including:

[0071] S301, calculate the actual range based on the first energy consumption at the current moment, and calculate the indicated range based on the second energy consumption at the current moment;

[0072] The first energy consumption is the short-term historical energy consumption, which can represent the current energy consumption level, and the second energy consumption is the long-term historical energy consumption, which can represent the historical energy consumption level. The actual range can be calculated based on the first energy consumption at the current time and the available energy, so as to ensure the accuracy of the actual range; the indicated range can be calculated based on the second energy consumption at the current time and the available energy, so as to ensure the stability of the indicated range. The calculated actual range and indicated range are both for the reasonable display of the target display interface in the subsequent steps. The target display interface will inevitably involve the display of the range, that is, the indicated range on the conventional display interface before switching to the target display interface.

[0073] As before, the existing current range is obtained by dividing the available energy at the current time by the historical average energy consumption in the current driving mode in the vehicle historical data. In this step, the second energy consumption is used instead of the historical average energy consumption in the current driving mode in the vehicle historical data, which can effectively avoid the instantaneous large change of the indicated range caused by the driving mode switching. Moreover, the historical average energy consumption in the current driving mode in the vehicle historical data cannot represent the energy consumption level of the current driving mode. For example, the historical average energy consumption does not superimpose the factor of intense driving behavior, but the current driving mode may superimpose the factor of intense driving behavior. Therefore, compared with the historical average energy consumption, the second energy consumption can better reflect the energy consumption level of the current driving mode, thereby avoiding the situation that the indicated range is seriously inconsistent with the actual driving range. That is, the indicated range is calculated based on the second energy consumption, which ensures the relative stability of the indicated range display and also ensures the relative accuracy thereof.

[0074] S302, obtaining the change trend of the indicated range based on the actual range and the indicated range;

[0075] When the actual range is less than the indicated range, it indicates that the change trend of the indicated range is decreasing, and when the actual range is greater than the indicated range, it indicates that the change trend of the indicated range is increasing. The calculation of the change trend is also for the reasonable display of the subsequent target display interface.

[0076] S303, switching the current range display interface to the target display interface to display the change trend of the indicated range through the target display interface.

[0077] The target display interface can be displayed on the instrument panel or the HUD (Head-Up-Display, head-up display).

[0078] That is, the HUD or instrument panel displays the change trend of the indicated range S202. The change trend can be static display or animation display, and the user can intuitively see the influence of the current energy consumption switching behavior (driving mode switching or driving behavior switching, etc.) on the vehicle dynamic range through the target display interface, enhance the user's confidence in the vehicle range accuracy, and make the user have a clearer understanding of the vehicle dynamic range capability.

[0079] In this embodiment, the actual range is calculated by the first energy consumption, which is a short-term historical energy consumption, to ensure the accuracy of the actual range; and the indicated range is calculated by the second energy consumption, which is a long-term historical energy consumption, to ensure the relative stability and relative accuracy of the indicated range, which can avoid the instantaneous large change of the indicated range caused by driving mode switching and the situation that the indicated range is seriously inconsistent with the actual driving range. The change trend of the indicated range is obtained from the actual range and the indicated range, and the display mode of the change trend of the range is displayed through the target display interface, which can make the user intuitively see the influence of the current energy consumption switching behavior on the vehicle dynamic range through the target display interface, enhance the user's confidence in the vehicle range accuracy, and make the user have a clearer understanding of the vehicle dynamic range capability, effectively avoiding the range anxiety.

[0080] To further reflect the richness of the target display interface, in some embodiments, as shown in FIG. 4, the current range display interface in S102 is switched to the target display interface to display the change trend of the range through the target display interface, which includes:

[0081] S401, obtaining the minimum theoretical range and the maximum theoretical range at the current time;

[0082] As shown in FIG. 5, an exemplary obtaining process of this step is as follows:

[0083] S501, obtaining the vehicle speed information, driving mode and available energy at the current time;

[0084] The calculation process of the vehicle speed information at the current time includes:

[0085] The vehicle speed information at the previous time and the vehicle speed at the current time are obtained, and the vehicle speed information at the previous time and the vehicle speed at the current time are weighted according to a preset third weighting rule to obtain the vehicle speed information at the current time. In the third weighting rule, the weight ratio given to the vehicle speed at the current time is greater than the weight ratio given to the vehicle speed information at the previous time.

[0086] That is, the vehicle speed information at the current time is calculated by the self-learning manner in the foregoing embodiments. The third weighting rule involved in the calculation of the vehicle speed information gives a greater weight ratio to the vehicle speed at the current time. For example, the weight ratio of the vehicle speed information at the last time is 20%, and the weight ratio of the vehicle speed at the current time is 80%. That is, the vehicle speed information at the current time can accurately reflect the current vehicle speed level. When the first time for calculating the vehicle speed information, the vehicle speed information at the last time in the current driving scene during the last vehicle driving process stored in the EEPROM can be read as the vehicle speed information at the last time.

[0087] S502, determining the corresponding maximum theoretical energy consumption and minimum theoretical energy consumption based on the vehicle speed information at the current time and the driving mode;

[0088] The process can be to find the related data in the preset energy consumption database. The energy consumption database is used to reflect the relationship between the vehicle speed information and the corresponding maximum theoretical energy consumption and minimum theoretical energy consumption of the driving mode. For example, the maximum theoretical energy consumption corresponding to the vehicle speed information and the driving mode is the sum of the maximum driving energy consumption and the maximum auxiliary energy consumption corresponding to the vehicle speed information and the driving mode. The maximum auxiliary energy consumption is the sum of the auxiliary energy consumptions of all auxiliary devices under the maximum theoretical power. Similarly, the corresponding minimum theoretical energy consumption is the sum of the minimum driving energy consumption and the minimum auxiliary energy consumption corresponding to the vehicle speed information and the driving mode.

[0089] S503, calculating the minimum theoretical endurance mileage at the current time based on the available energy at the current time and the maximum theoretical energy consumption; and calculating the maximum theoretical endurance mileage at the current time based on the available energy at the current time and the minimum theoretical energy consumption.

[0090] In this step, the minimum theoretical endurance mileage at the current time is obtained by dividing the available energy at the current time by the maximum theoretical energy consumption; and the maximum theoretical endurance mileage at the current time is obtained by dividing the available energy at the current time by the minimum theoretical energy consumption.

[0091] S402, controlling the target display interface to display the change trend of the indicated endurance mileage to the maximum theoretical endurance mileage or the minimum theoretical endurance mileage.

[0092] Specific examples are as follows:

[0093] In response to determining that the change trend of the indicated endurance mileage is decreasing, the target display interface is controlled to display the change trend of the indicated endurance mileage to the minimum theoretical endurance mileage;

[0094] In response to determining that the change trend of the indicated endurance mileage is increasing, the target display interface is controlled to display the change trend of the indicated endurance mileage to the maximum theoretical endurance mileage.

[0095] In the process of displaying the target display interface, the actual range can not be embodied, i.e., only the change trend of the indicated range to the maximum or minimum theoretical range is embodied. Specifically, the indicated range and the minimum or maximum theoretical range are a progress bar, and a flashing arrow on the progress bar indicates the change trend. More specifically, as shown in FIG. 8, 300 km in the target display interface is the indicated range, 230 km is the minimum theoretical range, and the arrow on the progress bar represents the change trend of the indicated range.

[0096] In the process of displaying the target display interface, the actual range can also be displayed in the form of at least one of a numerical value, a color block, and an arrow. Specifically, the indicated range and the minimum or maximum theoretical range are a progress bar, and the numerical value, color block, or arrow representing the actual range can flash on the progress bar and can be displaced on the progress bar according to its own change. For example, when the change trend of the actual range is upward and the actual range is getting closer to the maximum theoretical range, the color block representing the actual range is also displaced on the progress bar to get closer to the maximum theoretical range. For another example, when the change trend of the actual range is downward and the actual range is getting closer to the minimum theoretical range, the color block representing the actual range is also displaced on the progress bar to get closer to the minimum theoretical range. More specifically, as shown in FIG. 9, 300 km in the target display interface is the indicated range, 230 km is the minimum theoretical range, and 230 km on the progress bar is the actual range. As shown in FIGS. 10 and 11, 300 km in the target display interface is the indicated range, MIN: 230 km is the minimum theoretical range, MAX: 400 km is the maximum theoretical range, the arrow on the progress bar represents the change trend, and 350 km or 250 km beside the progress bar is the actual range.

[0097] Compared with the foregoing embodiments, the target display interface of the present embodiment further includes the minimum theoretical range and the maximum theoretical range. That is, the target display interface can not only display the change trend of the indicated range to the actual range, but also display the change trend of the indicated range to the minimum or maximum theoretical range. In the process of displaying the change trend, the actual range can or can not be embodied. When the actual range is embodied, the actual range can be embodied in the form of a numerical value, a color block, or an arrow, so that the user has a clearer understanding of the dynamic range of the vehicle, i.e., more display forms of the indicated range are provided, and the richness of the target display interface is improved.

[0098] In addition, the target display interface can be switched back to the regular range display interface when the energy consumption difference becomes smaller or reaches the preset display duration. In other words, the target display interface can be switched back to the range display interface in response to determining that the energy consumption difference is less than or equal to the preset value or the target display interface display duration reaches the preset duration.

[0099] In addition, the target display interface cannot affect the display of other data on the instrument panel. For example, when an alarm data is displayed on the instrument panel, and the target display interface overlaps with the display interface of the alarm data, the alarm data display interface is used as the surface display interface, and the target display interface is used as the inner display interface.

[0100] It should be noted that the method of the embodiments of the present application can be executed by a single device, such as a computer or a server. The method of the embodiments of the present application can also be applied to a distributed scenario, and can be completed by multiple devices cooperating with each other. In this distributed scenario, one of the multiple devices can only execute one or more steps in the method of the embodiments of the present application, and the multiple devices can interact with each other to complete the range display method.
