[0021] The exemplary embodiments will be described in detail below with reference to the accompanying drawings.

[0022] The application provides a vehicle, which includes a vehicle range display control system and a display device electrically connected to the display control system. The display control system includes one or more processors for executing the display control method of the vehicle, and the display device is controlled by the display control system and used for displaying the range. The display device is, for example, an instrument installed in the vehicle.

[0023] In combination with Figure 1 The application provides a vehicle range display control method, which includes steps S10 to S50.

[0024] In step S10, the initial energy consumption value and the current actual energy consumption value of the vehicle are obtained.

[0025] In step S20, the energy consumption value between the initial energy consumption value and the actual energy consumption value is generated as a transition energy consumption value.

[0026] Step S30, a first difference value between the transition energy consumption value and the actual energy consumption value is calculated.

[0027] The first difference value here is the absolute value of the difference between the transition energy consumption value and the actual energy consumption value.

[0028] Step S40, if the first difference value is greater than an energy consumption threshold value, a transition range is determined based on the transition energy consumption value, and a display device of the vehicle is controlled to display the transition range.

[0029] Here, the energy consumption threshold value can be a fixed value set, for example, set to 2kW·h / 100km. In some embodiments, the energy consumption threshold value can be determined in real time according to the current running condition, for example, a set percentage of the actual energy consumption value currently obtained is taken as the energy consumption threshold value. More specifically, for example, 5% of the actual energy consumption value is taken as the energy consumption threshold value. The numerical value here is only an example, and the specific value of the energy consumption threshold value can be set according to actual needs in the implementation process. It can be understood that reducing the energy consumption threshold value is beneficial to improving the smoothness of the display change.

[0030] Step S50, if the first difference value is less than or equal to the energy consumption threshold value, an actual range is determined based on the actual energy consumption value, and the display device is controlled to display the actual range.

[0031] In at least some embodiments, the display control method is applied to the display control system described above, and the display device is used to display the transition range or the actual range.

[0032] By adopting the technical solutions provided in the embodiments of the present application, the transition energy consumption value between the initial energy consumption value and the actual energy consumption value is generated, and the transition range or the actual range is dynamically controlled based on the difference between the transition energy consumption value and the actual energy consumption value, so that the display value of the range can be smoothly transitioned from the initial state to the actual state, effectively avoiding the problem of range display jump caused by the large difference between the initial energy consumption value and the actual energy consumption value, and improving the smoothness of the range display of the vehicle, so that the user can more intuitively understand the change trend of the current range, thereby optimizing the driving experience of the user.

[0033] In combination with Figure 2 the embodiments of the present application provide another display control method for the range of a vehicle, including steps S111 to S50.

[0034] Step S111, after the vehicle is started and powered on, an average energy consumption value in a previous power-on period of the vehicle is obtained as an initial energy consumption value.

[0035] Step S120, an actual energy consumption value of the vehicle is obtained.

[0036] Step S20, generating an energy consumption value between the initial energy consumption value and the actual energy consumption value as a transition energy consumption value.

[0037] Step S30, calculating a first difference value between the transition energy consumption value and the actual energy consumption value.

[0038] Step S40, if the first difference value is greater than the energy consumption threshold value, determining a transition range based on the transition energy consumption value, and controlling the display device of the vehicle to display the transition range.

[0039] Step S50, if the first difference value is less than or equal to the energy consumption threshold value, determining an actual range based on the actual energy consumption value, and controlling the display device to display the actual range.

[0040] That is, the initial energy consumption value of the vehicle is obtained as follows: after the vehicle is powered on, an average energy consumption value in a previous power-on period of the vehicle is obtained as the initial energy consumption value. The previous power-on period here refers to the process from the last time the vehicle is powered on to the last time the vehicle is powered off. In this way, the initial energy consumption value is determined according to the historical running condition of the vehicle, which provides a more actual use scenario for the generation of the subsequent transition energy consumption value, and helps to avoid the deviation caused by the fixed initial value when the vehicle starts due to the lack of real-time energy consumption benchmark. For example, if the vehicle is in a full load state and has a high energy consumption in the previous period, the initial energy consumption value can inherit this feature, reduce the large gap between the initial value and the current actual energy consumption value when starting, lay a foundation for the subsequent smooth display of the range through the transition energy consumption value, avoid the range display mutation problem caused by the unreasonable initial value, and further ensure the continuity and smoothness of the range display process from starting to stable display, thereby helping to optimize the user experience.

[0041] In other embodiments, the initial energy consumption value can also be a fixed value.

[0042] In combination Figure 3 As shown in the figure, the embodiment of the present application provides another display control method of vehicle range, which includes steps S111 to S50.

[0043] Step S110, obtaining an initial energy consumption value of the vehicle.

[0044] Step S121, obtaining the current load condition, driving distance and energy consumption data of the vehicle.

[0045] Step S122, determining an average energy consumption value of the vehicle according to the load condition.

[0046] Step S123, determining a dynamic energy consumption value of the vehicle within a set time period according to the driving distance and the energy consumption data.

[0047] Step S124, determining an actual energy consumption value according to the average energy consumption value of the vehicle and the dynamic energy consumption value of the vehicle.

[0048] Step S20, generating an energy consumption value between the initial energy consumption value and the actual energy consumption value as a transition energy consumption value.

[0049] Step S30, calculating a first difference value between the transition energy consumption value and the actual energy consumption value.

[0050] Step S40, if the first difference value is greater than the energy consumption threshold value, determining a transition range based on the transition energy consumption value, and controlling the display device of the vehicle to display the transition range.

[0051] Step S50, if the first difference value is less than or equal to the energy consumption threshold value, determining an actual range based on the actual energy consumption value, and controlling the display device to display the actual range.

[0052] Here, the process of determining the actual energy consumption value is further described. Determining the average energy consumption value of the vehicle based on the current load condition can reflect the energy consumption characteristics of the vehicle under the current load condition. Determining the dynamic energy consumption value of the vehicle based on the driving range and energy consumption data within the set time can reflect the dynamic energy consumption changes of the vehicle in the recent driving process. Determining the actual energy consumption value based on the average energy consumption value and the dynamic energy consumption value of the vehicle can not only accurately match the current load state of the vehicle, but also quickly respond to changes in real-time driving conditions, which is beneficial to avoid the calculation lag caused by relying on cumulative average energy consumption, and is beneficial to avoid the calculation volatility caused by relying on instantaneous energy consumption, and is beneficial to improve the accuracy of the actual energy consumption value calculated, and is further beneficial to improve the accuracy of the actual range.

[0053] In some embodiments, determining the actual energy consumption value based on the average energy consumption value and the dynamic energy consumption value of the vehicle includes: determining the actual energy consumption value E b = k1*E a + k2*E d . k1 is a first coefficient, k2 is a second coefficient, E a is the average energy consumption value of the vehicle, E d is the dynamic energy consumption value of the vehicle; wherein the first coefficient k1 and the second coefficient k2 are both greater than 0, and the sum of the first coefficient k1 and the second coefficient k2 is 1. Here, the implementation process of determining the actual energy consumption value based on the average energy consumption value and the dynamic energy consumption value of the vehicle is described in detail. The actual energy consumption value calculated by this calculation method can not only accurately match the current load state of the vehicle, but also quickly respond to changes in real-time driving conditions, which is beneficial to improve the accuracy of the actual energy consumption value calculated, and is further beneficial to improve the accuracy of the actual range.

[0054] In particular, in some embodiments, the first coefficient k1 is greater than the second coefficient k2. That is, the first coefficient k1 is greater than 0.5. In the calculation of the actual energy consumption value, a higher weight is set for the average energy consumption value of the whole vehicle, which can effectively reduce the risk of the actual energy consumption value fluctuating sharply due to the whole vehicle dynamic energy consumption value fluctuating sharply due to factors such as road condition changes and driving behavior mutations, thereby playing a certain noise reduction effect, making the calculated actual energy consumption value more stable, and avoiding frequent jumping. In this way, while retaining the responsiveness of dynamic energy consumption to real-time state, the more stable load is used as the main determination basis for the actual energy consumption value, which can more smoothly reflect the dynamic changes of the actual energy consumption value, and provide a more reliable basis for the generation of subsequent transitional energy consumption values and the smooth display of the range. Further, in some embodiments, the first coefficient k1 is greater than or equal to 0.8. For example, it can be set to 0.9. That is, the actual energy consumption value E b = 0.9 * E a + 0.1 * E d .

[0055] In some embodiments, the load condition includes the vehicle mass. Determining the average energy consumption value of the whole vehicle according to the load condition includes: determining, according to a corresponding relationship between the mass and the energy consumption value of the whole vehicle, the energy consumption value of the whole vehicle corresponding to the current mass of the whole vehicle as the average energy consumption value of the whole vehicle. The corresponding relationship between the mass and the energy consumption value of the whole vehicle is stored in advance, and after the current mass of the whole vehicle is determined in the implementation process, the energy consumption value of the whole vehicle corresponding to the current mass of the whole vehicle is determined according to the corresponding relationship as the average energy consumption value of the whole vehicle, which is used in the subsequent calculation process of the actual energy consumption value. The corresponding relationship between the mass and the energy consumption value of the whole vehicle can be stored in the form of a mapping relationship table or a formula.

[0056] In some embodiments, the vehicle mass is input by the user through an input device. In some embodiments, the vehicle mass is obtained by real-time detection. Specifically, the range display control method of the vehicle further includes: obtaining the current acceleration of the whole vehicle, and calculating the mass of the whole vehicle according to the acceleration of the whole vehicle. In this way, the real-time and accuracy of the mass of the whole vehicle can be ensured, which is conducive to ensuring the accuracy of the average energy consumption value of the whole vehicle and further the real-time energy consumption value.

[0057] In some embodiments, the load condition includes a current load state, and the current load state is one of an empty load state, a half load state, a full load state, and an overload state. Determining the average energy consumption value of the whole vehicle according to the load condition includes: determining, according to a corresponding relationship between the load state and the energy consumption value of the whole vehicle, the energy consumption value of the whole vehicle corresponding to the current load state as the average energy consumption value of the whole vehicle.

[0058] In some embodiments, the current load state is input by the user through the input device. In some embodiments, the current load state can be determined from the total vehicle mass among a plurality of load states. In some embodiments, the user can directly input the current total vehicle mass through the input device, or the current total vehicle mass can be detected in real time. Specifically, each of the plurality of load states corresponds to a total vehicle mass interval, and if the current total vehicle mass is within the total vehicle mass interval corresponding to a load state, the current load state is determined to be the load state. Specifically, the plurality of load states includes at least one of an empty load state, a half load state, a full load state, and an overload state. Each of the plurality of load states corresponds to a total vehicle mass interval, and if the current total vehicle mass is within the total vehicle mass interval corresponding to a load state, the current load state is determined to be the load state.

[0059] In some embodiments, the energy consumption value between the initial energy consumption value and the actual energy consumption value is generated as a transition energy consumption value, including: from the initial energy consumption value to the actual energy consumption value, generating a transition energy consumption value every target value. Calculate the first difference value between the transition energy consumption value and the actual energy consumption value, including: sequentially calculate the first difference value between the plurality of transition energy consumption values and the actual energy consumption value. In the process of generating a transition energy consumption value every target value from the initial energy consumption value to the actual energy consumption value, the generated transition energy consumption value gradually approaches the actual energy consumption value from the initial energy consumption value. In this way, when the first difference value between the transition energy consumption value and the actual energy consumption value is greater than the energy consumption threshold, the transition range displayed by the display device also gradually approaches the actual range, which can reflect the actual trend of the current actual range through the display of the display device, and is beneficial to the user to understand the change of the range in real time. That is, the transition energy consumption value E c =E0+ΔE. E0 is the initial energy consumption value, and ΔE is the target value. If the transition energy consumption value E c calculated at this time is greater than the first difference value between the actual energy consumption value, the transition range is determined according to the transition energy consumption value, and the display device of the vehicle is controlled to display the transition range. It is still necessary to continue to calculate the next transition energy consumption value. At this time, the transition energy consumption value E c =E0+ΔE+ΔE. In this way, it is not necessary to repeat here.

[0060] In some embodiments, the target value is a pre-set fixed value. In some embodiments, the target value is determined according to the initial energy consumption value and the actual energy consumption value. Specifically, in some embodiments, the display control method further comprises: calculating a second difference value between the initial energy consumption value and the actual energy consumption value, and determining the target value according to the second difference value. Wherein the target value is positively correlated with the second difference value. In this way, the target value is determined according to the second interpolation between the initial energy consumption value and the actual energy consumption value in the implementation process, so that the target value is more in line with the current actual demand. Specifically, when the initial energy consumption value and the actual energy consumption value have a large difference, i.e. the second difference value is large, the target value is correspondingly increased, which can relatively reduce the generation quantity of the transition energy consumption value, while ensuring smooth transition, it is beneficial to speed up the approach to the actual energy consumption value, and avoid the process of approaching the actual energy consumption value being too long. When the difference between the two is small, i.e. the second difference value is small, the target value is correspondingly reduced, and a more fine gradient transition is achieved by increasing the generation quantity of the transition energy consumption value. In this way, the transition process can adapt to the fast convergence requirement under large energy consumption difference, and can maintain the smoothness of the display under small difference scenario, avoiding the problem of slow transition or jump caused by fixed target value, further optimizing the smoothness and response speed of the range display, and thus optimizing the user experience.

[0061] In some embodiments, the transition energy consumption value is generated every target value, which comprises comparing the initial energy consumption value and the actual energy consumption value of the vehicle by difference, and the initial energy consumption value constantly approaches the actual energy consumption value according to a set slope, and the transition energy consumption value is generated every set time length in the approaching process. The greater the set slope, the faster the approaching process from the initial energy consumption value to the actual energy consumption value, which corresponds to the larger energy consumption of the target value, and can avoid the approaching process to the actual energy consumption value being too long and the transition energy consumption value being too much.

[0062] i.e. the transition energy consumption value E0 is the initial energy consumption value, t is the time, corresponding to the target value. If the transition energy consumption value E c is greater than the energy threshold value, the transition range is determined according to the transition energy consumption value, and the display device of the vehicle is controlled to display the transition range. It is still necessary to continue to calculate the next transition energy consumption value. At this time, the transition energy consumption value By analogy, it is not repeated here.

[0063] In some embodiments, the display control method further comprises: obtaining the residual energy value of the vehicle. Determining the transition range based on the transition energy consumption value comprises: calculating the quotient value obtained by dividing the residual energy value by the transition energy consumption value as the transition range; and / or, determining the actual range based on the actual energy consumption value, comprising: calculating the quotient value obtained by dividing the residual energy value by the actual energy consumption value as the actual range.

[0064] In combination Figure 4 As shown in FIG. 1, the embodiment of the present application provides another display control method of vehicle range, comprising steps S10 to S500,

[0065] In step S10, an initial energy consumption value and a current actual energy consumption value of the vehicle are obtained.

[0066] In step S20, an energy consumption value between the initial energy consumption value and the actual energy consumption value is generated as a transition energy consumption value.

[0067] In step S30, a first difference value between the transition energy consumption value and the actual energy consumption value is calculated.

[0068] In step S60, a remaining energy value of the vehicle is obtained.

[0069] In step S400, if the first difference value is greater than an energy consumption threshold value, a quotient value obtained by dividing the remaining energy value by the transition energy consumption value is calculated as a transition range, and a display device of the vehicle is controlled to display the transition range.

[0070] In step S500, if the first difference value is less than or equal to the energy consumption threshold value, a quotient value obtained by dividing the remaining energy value by the actual energy consumption value is calculated as an actual range, and the display device is controlled to display the actual range.

[0071] In this way, the transition range corresponding to the transition energy consumption value can be calculated according to the remaining energy value and the transition energy consumption value, and the actual range corresponding to the actual energy consumption value can be calculated according to the remaining energy value and the actual energy consumption, so as to guarantee the accuracy of the calculation of the transition range and the actual range.

[0072] Specifically, in some embodiments, the vehicle is a fuel vehicle, and at this time, the remaining energy value includes an energy value corresponding to a remaining oil volume V. For example, in some embodiments, the quotient value obtained by dividing the remaining energy by the transition energy consumption value is calculated as the transition range, including: determining the transition range L1=(V*N) / E c In some embodiments, the quotient value obtained by dividing the remaining energy value by the actual energy consumption value is calculated as the actual range, including: determining the actual range L2=(V*N) / E b . Wherein N is an oil-electric conversion rate, (V*N) is an energy value corresponding to the remaining oil volume V, and E c is the transition energy consumption value.

[0073] In some embodiments, the vehicle is a pure electric vehicle, and at this time, the remaining energy value includes a remaining electricity volume B. In some embodiments, the quotient value obtained by dividing the remaining energy by the transition energy consumption value is calculated as the transition range, including: determining the transition range L1=B / E cIn some embodiments, the actual range is calculated as a quotient of the remaining energy value divided by the actual energy consumption value, including: determining the actual range L2 = B / E b .

[0074] In some embodiments, the vehicle is a hybrid vehicle, and the remaining energy value includes energy values corresponding to the remaining electric quantity B and the remaining oil quantity V. In some embodiments, the transition range is calculated as a quotient of the remaining energy divided by the transition energy consumption value, including: determining the transition range L1 = (B + V*N) / E c In some embodiments, the actual range is calculated as a quotient of the remaining energy value divided by the actual energy consumption value, including: determining the actual range L2 = (B + V*N) / E b . Wherein N is an oil-electric conversion rate, (V*N) is an energy value corresponding to the remaining oil quantity V, and E c is the transition energy consumption value.

[0077] In step S102, the current acceleration of the vehicle is obtained, and the vehicle mass is determined according to the current acceleration of the vehicle.

[0080] In step S104, the current driving range and energy consumption data of the vehicle are obtained, and the vehicle dynamic energy consumption value in a set time period is determined according to the driving range and the energy consumption data.

[0081] In step S105, the actual energy consumption value is determined according to the vehicle average energy consumption value and the vehicle dynamic energy consumption value.

[0082] In step S106, the average energy consumption value in the previous power-on period of the vehicle is obtained as an initial energy consumption value.

[0083] In step S107, the energy consumption value between the initial energy consumption value and the actual energy consumption value is generated as a transition energy consumption value.

[0084] In step S108, it is determined whether a first difference between the transition energy consumption value and the actual energy consumption value is greater than an energy consumption threshold.

[0085] If the first difference is greater than the energy consumption threshold, step S109 is performed; if the first difference is less than or equal to the energy consumption threshold, step S110 is performed.

[0086] In step S109, a transition range is determined based on the transition energy consumption value, and a display device of the vehicle is controlled to display the transition range. After step S109 is performed, steps S107 and S108 are continuously performed.
