[0023] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0024] A vehicle range correction method, device, vehicle, storage medium and program of embodiments of the present application are described below with reference to the drawings.

[0025] Specifically, Figure 1 A flowchart of a vehicle range correction method provided by embodiments of the present application is shown.

[0026] As Figure 1 shown, the vehicle range correction method includes the following steps:

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

[0028] It can be understood that the embodiments of the present application can identify the current driving mode of the vehicle in order to correct the vehicle range.

[0029] It should be noted that the driving mode includes but is not limited to the economy mode, the normal mode and the sports mode, which can be determined according to the physical or touch driving mode selector inside the vehicle. The state change of the driving mode selector will be captured by the sensor and sent to the vehicle control unit through the CAN bus or other communication protocol.

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

[0031] It can be understood that the embodiments of the present application can determine the corresponding reference range according to the current driving mode, and obtain the remaining percentage of the current power battery, in order to calculate the actual remaining range according to the reference range subsequently.

[0032] In the embodiments of the present application, the corresponding reference range is determined according to the current driving mode, including: querying the preset database to obtain the corresponding reference range in the current driving mode.

[0033] The preset database can be set according to actual needs, which is not limited specifically.

[0034] It can be understood that the embodiments of the present application can query the preset database to obtain the corresponding reference range in the current driving mode, in order to calculate the actual remaining range according to the reference range subsequently.

[0035] It should be noted that each driving mode of the present application is one-to-one mapped and stored with the corresponding reference range to the preset database for subsequent direct lookup of the database; the power battery is provided with a battery management system responsible for monitoring the state of the battery, including the remaining power, temperature, voltage and other parameters, and the current power battery remaining power percentage can be directly obtained.

[0036] In step S103, the initial remaining range is calculated according to the remaining power percentage and the reference range, and the driving mode switching intention of the user and / or the air conditioning system data are identified.

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

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

[0039] It can be understood that the embodiments of the present application can correct the initial remaining range to obtain the actual remaining range according to the driving mode switching intention and / or the air conditioning system data, which improves the accuracy of the vehicle range and improves the user experience.

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

[0041] If the user switches to "sport mode", where the CLTC range is 560 kilometers, and the battery remaining power remains unchanged, then the remaining range is calculated as follows: R = 560km x 0.8 = 448km Rinitial = 560km x 0.8 = 448km.

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

[0043] In the embodiment of the present application, the actual remaining cruising range is obtained by correcting the initial remaining cruising range according to the driving mode switching intention, including: if the driving mode switching intention is to switch the driving mode to the target driving mode, determining the corresponding reference cruising range according to the target driving model, and calculating the actual remaining cruising range according to the remaining power percentage at the switching time and the reference cruising range.

[0044] It can be understood that the embodiment of the present application can quickly respond when the user intends to switch the driving mode, provide instant updated remaining cruising range estimation, not only improve the accuracy of the cruising range estimation, but also enhance the user's trust and satisfaction, and reduce the anxiety caused by inaccurate estimation.

[0045] In the embodiment of the present application, the actual remaining cruising range is obtained by correcting the initial remaining cruising range according to the air conditioning system data, 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 obtaining the total power consumption value by weighting the power consumption per 100 kilometers of the air conditioning system and the basic power consumption in the current driving mode; and correcting the initial remaining cruising range to obtain the actual remaining cruising range according to the total power consumption value and the remaining power of the power battery at the current time.

[0046] It can be understood that the embodiment of the present application can obtain current data and voltage data in the air conditioning system data of the air conditioning system; calculate the power consumption of the air conditioning system according to the current data and the voltage data; calculate the power consumption per 100 kilometers of the air conditioning system according to the power consumption, and obtain the total power consumption value by weighting the power consumption per 100 kilometers of the air conditioning system and the basic power consumption in the current driving mode; and correct the initial remaining cruising range to obtain the actual remaining cruising range according to the total power consumption value and the remaining power of the power battery at the current time, quickly respond after the user starts the air conditioner, consider the additional energy consumption of the air conditioning system, provide instant updated remaining cruising range estimation, not only improve the accuracy of the cruising range estimation, but also enhance the user's trust and satisfaction, and reduce the anxiety caused by inaccurate estimation.

[0047] Specifically, the real-time current and voltage data are read from the air conditioning control system, the power consumption P of the air conditioning system is calculated as P=V×I, the driving time T required for the vehicle to travel 100 kilometers is determined according to the average speed in the CLTC or WLTC standard cycle test working condition, for example: in the CLTC working condition, the average speed is 28.96 km / h, and the time required for 100 km is 3.45 hours; in the WLTC working condition, the average speed is 46.5 km / h, and the time required for 100 km is 2.15 hours; the calculation formula of the power consumption per 100 kilometers of the air conditioning system is E=P×T, and 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 at the vehicle end.

[0048] For example, assuming that the vehicle has a CLTC range of 560 kilometers in "sport mode" and the current power battery remaining power is 80%, 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 2 kW, and the time required for 100 km under the CLTC working condition is 3.45 hours, then the power consumption per 100 km of the air conditioning system E = 2 kW x 3.45 h = 6.9 kWh / 100 km, assuming that the basic power consumption in "sport mode" is 15 kWh / 100 km, then the corrected total power consumption is: 21.9 kWh / 100 km, if the full capacity of the battery is 60 kWh, then the corrected actual remaining range is calculated as follows: Ractual = 21.9 kWh / 100 km x 60 kWh x 0.8 = 220.1 km.

[0049] In the embodiment of the present application, the actual remaining range is obtained by correcting the initial remaining range according to the driving mode switching intention and the air conditioning system data, which includes: calculating the basic vehicle end power consumption of the target driving mode according to the target driving mode; calculating the power consumption per 100 km of the air conditioning system according to the air conditioning system data; obtaining the corrected total power consumption value according to the basic vehicle end power consumption of the target driving mode and the power consumption per 100 km of the air conditioning system; correcting the initial remaining range according to the corrected total power consumption value and the remaining power of the power battery to obtain the actual remaining range.

[0050] It can be understood that the embodiment of the present application calculates the basic vehicle end power consumption of the target driving mode according to the target driving mode; calculates the power consumption per 100 km of the air conditioning system according to the air conditioning system data; obtains the corrected total power consumption value according to the basic vehicle end power consumption of the target driving mode and the power consumption per 100 km of the air conditioning system; corrects the initial remaining range according to the corrected total power consumption value and the remaining power of the power battery to obtain the actual remaining range, which quickly responds after the user turns on the air conditioner, considers the additional energy consumption of the air conditioning system, provides instant updated remaining range estimation, and considers the basic power consumption under the driving mode switching, which not only improves the accuracy of the range estimation, but also enhances the user's trust and satisfaction, and reduces the anxiety caused by inaccurate estimation.

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

[0052] It can be understood that the embodiment of the present application can display the actual remaining range on the instrument panel, which is more intuitive to improve the user experience.

[0053] According to the vehicle endurance mileage correction method provided in the embodiment of the present application, the current driving mode of the vehicle is identified; the corresponding reference endurance mileage is determined according to the current driving mode, and the remaining percentage of the power battery is obtained; the initial remaining endurance mileage is calculated according to the remaining percentage of the power battery and the reference endurance mileage, and the driving mode switching intention of the user and / or the air conditioning system data are identified; the initial remaining endurance mileage is corrected to obtain the actual remaining endurance mileage according to the driving mode switching intention and / or the air conditioning system data, so that the display value of the remaining pure electric endurance mileage is as close as possible to the actual drivable mileage, the endurance anxiety of the customer is reduced, and the vehicle experience of the user is improved.

[0054] The vehicle endurance mileage correction method of the present application will be described in detail below. Figure 2 and Figure 3 The vehicle endurance mileage correction method of the present application will be described in detail below.

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

[0056] Step S2: The VCU corrects the pure electric endurance mileage according to the driving mode switching. That is, different driving modes correspond to different CLTC or WLTC standard cycle pure electric endurance mileage, for example: the economic mode corresponds to the CLTC pure electric endurance mileage of 600km, and the sport mode corresponds to the CLTC pure electric endurance mileage of 560km. The pure electric endurance mileage value is measured during the development stage of the vehicle. The VCU reads the remaining percentage of the battery value through CAN communication, and multiplies the value by the CLTC or WLTC standard cycle pure electric endurance mileage under different driving modes to obtain the initial remaining pure electric endurance mileage.

[0057] When the user switches the driving mode, the VCU reads the information of the driving mode, reads the remaining percentage of the battery value through CAN communication, and multiplies the value by the CLTC or WLTC standard cycle pure electric endurance mileage under the mode to obtain the corrected remaining pure electric endurance mileage information. Then the instrument display is switched from the initial remaining pure electric endurance mileage to the corrected remaining pure electric endurance mileage.

[0058] Step S3: The VCU corrects the pure electric cruising range according to the air conditioning setting. That is, after the driver turns on the air conditioner, the VCU reads the current and voltage information of the air conditioning system through CAN communication, calculates the power consumption of the system, and obtains the driving time required for 100 km (3.45 h under the CLTC condition, and 2.15 h under the WLTC condition) according to the average speed under the CLTC or WLTC standard cycle test condition. The power consumption of the air conditioning system per 100 km is obtained by multiplying the power consumption of the air conditioning system by the driving time required for 100 km. The VCU corrects the total power consumption at the end of the vehicle by adding the power consumption of the air conditioning system per 100 km to the power consumption at the end of the vehicle under the CLTC or WLTC condition. The VCU reads the remaining battery capacity percentage value through CAN communication, multiplies the available battery capacity to obtain the remaining available capacity, and divides the remaining available capacity by the corrected total power consumption at the end of the vehicle to obtain the corrected remaining pure electric cruising range. After the air conditioner is turned on, the instrument 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.
