[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] The following describes the vehicle range correction method, device, vehicle, storage medium and program of the embodiments of the present application with reference to the accompanying drawings.

[0025] Specifically, Figure 1 A flowchart of a method for correcting vehicle cruising range provided in an embodiment of the present application.

[0026] like Figure 1 As shown, the method for correcting the vehicle's cruising range includes the following steps:

[0027] In step S101 , the current driving mode of the vehicle is identified.

[0028] It is understandable that the embodiments of the present application can identify the current driving mode of the vehicle to facilitate the correction of the vehicle's cruising range.

[0029] It should be noted that driving modes include but are not limited to economy mode, normal mode and sports mode, which can be determined based on the physical or touch-type driving mode selector inside the vehicle. The state changes of the driving mode selector will be captured by the sensor and sent to the vehicle control unit via the CAN bus or other communication protocols.

[0030] In step S102, the corresponding reference cruising range is determined according to the current driving mode, and the remaining power percentage of the current power battery is obtained.

[0031] It is understandable that the embodiment of the present application can determine the corresponding reference cruising range according to the current driving mode, and obtain the remaining power percentage of the current power battery, so as to facilitate the subsequent calculation of the actual remaining cruising range based on the reference cruising range.

[0032] In an embodiment of the present application, determining a corresponding reference cruising range according to a current driving mode includes: querying a preset database with the current driving mode to obtain a corresponding reference cruising range.

[0033] Among them, the preset database can be set according to actual needs without specific limitation.

[0034] It is understandable that the embodiment of the present application can query the preset database with the current driving mode to obtain the corresponding reference cruising range, so as to facilitate the subsequent calculation of the actual remaining cruising range based on the reference cruising range.

[0035] It should be noted that each driving mode of the present application and the corresponding reference cruising range are mapped one by one and stored in a preset database, so as to facilitate subsequent direct database search and acquisition; the power battery is equipped with a battery management system responsible for monitoring the status of the battery, including remaining power, temperature, voltage and other parameters, and can directly obtain the current remaining power percentage of the power battery.

[0036] In step S103, the initial remaining cruising range is calculated based on the remaining power percentage and the reference cruising range, and the user's driving mode switching intention and / or air conditioning system data are identified.

[0037] It can be understood that the embodiments of the present application can calculate the initial remaining cruising range based on the remaining power percentage and the reference cruising range, and identify the user's driving mode switching intention and / or air-conditioning system data, so as to subsequently correct the initial remaining cruising range according to the driving mode switching intention and / or the air-conditioning system data to obtain the actual remaining cruising range.

[0038] In step S104, the initial remaining cruising range is corrected according to the driving mode switching intention and / or the air conditioning system data to obtain the actual remaining cruising range.

[0039] It can be understood that the embodiment of the present application can correct the initial remaining cruising range according to the driving mode switching intention and / or the air-conditioning system data to obtain the actual remaining cruising range, thereby improving the accuracy of the vehicle's cruising range and improving the user experience.

[0040] For example, assuming that the vehicle's CLTC range in "economic mode" is 600 kilometers, and the current remaining power of the power battery is 80%, the initial remaining range is calculated as follows: R = 600km×0.8=480kmRinitial=600km×0.8=480km.

[0041] If the user switches to "Sport Mode" with a CLTC range of 560 km and the remaining battery power remains unchanged, the remaining range is calculated as follows: R = 560 km × 0.8 = 448 km R initial = 560 km × 0.8 = 448 km.

[0042] If the air conditioner is turned on at this time, the VCU calculates that the air conditioning system consumes 2kWh per 100 kilometers, and the basic power consumption is 15kWh / 100km, so the corrected total power consumption on the vehicle side is 17kWh / 100km. If the full capacity of the battery is 60kWh, then the corrected remaining cruising range is calculated as follows: R = 60kWh × 0.817kWh / 100km ≈ 282.35km.

[0043] In an embodiment of the present application, the initial remaining cruising range is corrected according to the driving mode switching intention to obtain the actual remaining cruising range, including: if the driving mode switching intention is to switch the driving mode to the target driving mode, the corresponding reference cruising range is determined according to the target driving model, and the actual remaining cruising range is calculated according to the remaining power percentage at the switching time and the reference cruising range.

[0044] It can be understood that the embodiments of the present application can respond quickly when the user intends to switch driving modes and provide an instantly updated remaining range estimate, which not only improves the accuracy of the range estimate, but also enhances the user's trust and satisfaction, and reduces the anxiety caused by inaccurate estimates.

[0045] In an embodiment of the present application, the initial remaining cruising range is corrected according to the air-conditioning system data to obtain the actual remaining cruising range, including: obtaining current data and voltage data in the air-conditioning system data of the air-conditioning system; calculating the power consumption of the air-conditioning system according to the current data and the voltage data; calculating the power consumption per 100 kilometers of the air-conditioning system according to the power consumption, and weighting the power consumption per 100 kilometers of the air-conditioning system and the basic power consumption in the current driving mode to obtain the total power consumption value; correcting the initial remaining cruising range according to the total power consumption value and the remaining power of the power battery at the current moment to obtain the actual remaining cruising range.

[0046] It can be understood that the embodiments of the present application can obtain current data and voltage data from the air-conditioning system data of the air-conditioning system; calculate the power consumption of the air-conditioning system based on the current data and the voltage data; calculate the power consumption per 100 kilometers of the air-conditioning system based on the power consumption, and weight the total power consumption value according to the power consumption per 100 kilometers of the air-conditioning system and the basic power consumption in the current driving mode; correct the initial remaining cruising range according to the total power consumption value and the remaining power of the power battery at the current moment to obtain the actual remaining cruising range, respond quickly after the user turns on the air conditioner, take into account the additional energy consumption of the air-conditioning system, and provide an instantly updated remaining cruising range estimate, which not only improves the accuracy of the cruising range estimate, but also enhances the user's trust and satisfaction, and reduces the anxiety caused by inaccurate estimates.

[0047] Specifically, real-time current and voltage data are read from the air-conditioning control system, and the power consumption of the air-conditioning system P=V×I is calculated. The driving time T required for the vehicle to travel 100 kilometers is determined according to the average vehicle speed under the CLTC or WLTC standard cycle test conditions. For example: under CLTC conditions, the average vehicle speed is 28.96km / h, and the time required for 100km is 3.45 hours; under WLTC conditions, the average vehicle speed is 46.5km / h, and the time required for 100km is 2.15 hours; the calculation formula for the air-conditioning system's power consumption per 100 kilometers is: E=P×T. The power consumption per 100 kilometers of the air-conditioning system is added to the basic power consumption in the current driving mode to obtain the corrected total power consumption value on the vehicle side.

[0048] For example, assuming that the vehicle has a CLTC range of 560 kilometers in "sports mode" and the current remaining power of the power battery is 80%, then the initial remaining pure electric range is 448 kilometers. If the air conditioner is turned on at this time, the VCU calculates that the power consumption of the air conditioning system is 2kW, and the time required for 100km under CLTC conditions is 3.45 hours, then the air conditioning system's 100-kilometer power consumption E = 2kW × 3.45h = 6.9kWh / 100km, assuming that the basic power consumption in "sports mode" is 15kWh / 100km, then the corrected total power consumption of the vehicle is: 21.9kWh / 100km, if the full charge capacity of the battery is 60kWh, then the corrected actual remaining range is calculated as follows: Ractual = 21.9kWh / 100km60kWh×0.8≈220.1km.

[0049] In an embodiment of the present application, the initial remaining cruising range is corrected according to the driving mode switching intention and the air-conditioning system data to obtain the actual remaining cruising range, including: calculating the basic vehicle-side power consumption of the target driving mode according to the target driving mode; calculating the power consumption of the air-conditioning system per 100 kilometers according to the air-conditioning system data; obtaining a corrected total power consumption value according to the basic vehicle-side power consumption of the target driving mode and the power consumption of the air-conditioning system per 100 kilometers; and correcting the initial remaining cruising range according to the corrected total power consumption value and the remaining power of the power battery to obtain the actual remaining cruising range.

[0050] It can be understood that the embodiment of the present application calculates the basic vehicle-side power consumption of the target driving mode according to the target driving mode; calculates the power consumption of the air-conditioning system per 100 kilometers according to the air-conditioning system data; obtains a corrected total power consumption value based on the basic vehicle-side power consumption of the target driving mode and the power consumption of the air-conditioning system per 100 kilometers; corrects the initial remaining cruising range according to the corrected total power consumption value and the remaining power of the power battery to obtain the actual remaining cruising range, responds quickly after the user turns on the air conditioner, takes into account the additional energy consumption of the air-conditioning system, provides instantly updated remaining cruising range estimate, and takes into account the basic power consumption when switching driving modes, which not only improves the accuracy of the cruising range estimate, but also enhances the user's trust and satisfaction, and reduces the anxiety caused by inaccurate estimates.

[0051] In an embodiment of the present application, after correcting the initial remaining cruising range according to the driving mode switching intention and / or the air-conditioning system data to obtain the actual remaining cruising range, the method includes: displaying the actual remaining cruising range on the instrument panel.

[0052] It is understandable that the embodiment of the present application can display the actual remaining cruising range on the dashboard, which is more intuitive and improves the user experience.

[0053] According to the vehicle range correction method proposed in the embodiment of the present application, the current driving mode of the vehicle is identified; the corresponding reference range is determined according to the current driving mode, and the remaining power percentage of the current power battery is obtained; the initial remaining range is calculated according to the remaining power percentage and the reference range, and the user's driving mode switching intention and / or air-conditioning system data are identified; the initial remaining range is corrected according to the driving mode switching intention and / or the air-conditioning system data to obtain the actual remaining range, so that the displayed value of the remaining pure electric range is as close as possible to the actual drivable mileage, thereby reducing customers' range anxiety and improving users' car experience.

[0054] The following will be combined Figure 2 and Figure 3 The method for correcting the vehicle cruising range of the present application is described in detail as follows:

[0055] Step S1: The VCU calculates the CLTC or WLTC standard cycle pure electric range under different driving modes.

[0056] Step S2: VCU switches and corrects the pure electric cruising range according to the driving mode. That is, different driving modes correspond to different CLTC or WLTC standard cycle pure electric cruising ranges, for example: the economy mode corresponds to a CLTC pure electric cruising range of 600km, and the sports mode corresponds to a CLTC pure electric cruising range of 560km. The pure electric cruising range value is measured during the vehicle development stage. VCU reads the battery remaining power percentage value based on CAN communication, and uses this value to multiply the CLTC or WLTC standard cycle pure electric cruising range under different driving modes to obtain the initial remaining pure electric cruising range.

[0057] When the user switches the driving mode, the VCU reads the driving mode information, reads the battery remaining power percentage based on CAN communication, and multiplies this percentage by the CLTC or WLTC standard cycle pure electric range in this mode to obtain the corrected remaining pure electric range information. The instrument display then switches from the initial remaining pure electric range to the corrected remaining pure electric range.

[0058] Step S3: VCU corrects the pure electric cruising range according to the air conditioning settings. That is, after the driver turns on the air conditioning, VCU reads the current and voltage information of the air conditioning system according to the CAN communication and calculates the power consumption of the system. The average vehicle speed under the CLTC or WLTC standard cycle test conditions can be used to obtain the driving time required for 100km (under CLTC conditions, the average vehicle speed is 28.96km / h, and the time required for 100km is 3.45h; under WLTC conditions, the average vehicle speed is 46.5km / h, and the time required for 100km is 2.15h). The power consumption information of the air conditioning system is multiplied by the driving time required for 100km to obtain the power consumption per 100km of the air conditioning system. VCU obtains the corrected total power consumption value of the vehicle end based on the calculated power consumption per 100km of the air conditioning system and the vehicle-end power consumption under CLTC or WLTC conditions. The VCU reads the percentage of the remaining battery power through CAN communication, multiplies it by the available battery power, and obtains the remaining available power. The remaining available power is divided by the corrected total power consumption value on the vehicle side to obtain the corrected remaining pure electric cruising range. After turning on the air conditioner, the instrument panel displays the corrected remaining pure electric cruising range.

[0059] Step S4: the instrument displays the final pure electric cruising range, that is, the instrument displays the final corrected remaining pure electric cruising range.

[0060] Next, a device for correcting the vehicle cruising range proposed in an embodiment of the present application will be described with reference to the accompanying drawings.

[0062] like Figure 4 As shown, the vehicle cruising range correction device 10 includes: an identification module 100, a processing module 200, a calculation module 300 and a correction module 400.
