[0038] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0040] Please refer to Figure 1 , Figure 1 A flow chart of a method for predicting vehicle available time provided by an embodiment of the present invention, the method comprising:

[0041] S101: Acquire the current ambient temperature and the set temperature, and determine the variable power consumption of the vehicle in the current operating mode based on the current ambient temperature and the set temperature.

[0042] In this embodiment, the current ambient temperature refers to the ambient temperature at the current moment, and the set temperature is the required temperature in the vehicle set by the user, that is, the air-conditioning temperature set by the user.

[0043] In this embodiment, considering that the ambient temperature will change with time, the power consumption of the vehicle in the current operating mode will also change with time. Therefore, the embodiment of the present invention can continuously obtain the current ambient temperature, and calculate the variable power consumption of the vehicle in the current operating mode in real time through the current ambient temperature and the set temperature, so as to adapt to environmental changes and realize accurate prediction of the available time of the vehicle.

[0044] S102: Predicting the available time of the vehicle according to the variable power consumption of the vehicle in the current operating mode and the preset fixed power consumption of the vehicle in the current operating mode.

[0045] In this embodiment, the fixed power consumption can be represented by the low-voltage power of the vehicle. The vehicle is provided with an electric power system capable of providing high-voltage energy and low-voltage energy, wherein the high-voltage energy is usually provided to the vehicle's traction system, transmission system and other high-voltage systems, and the low-voltage energy is usually provided to the lighting system, multimedia system and other low-voltage systems. The low-voltage power of the vehicle described in the embodiment of the present invention refers to the low-voltage electric power on the vehicle or the power of the low-voltage system on the vehicle.

[0046] In this embodiment, taking into account the differences in power consumption of the vehicle in different operating modes, the fixed power consumption of the vehicle in different operating modes can be tested in advance through actual vehicle tests or simulation tests. When predicting the available time of the vehicle later, the "fixed power consumption in the current operating mode obtained in advance" can be directly obtained (that is, the "preset fixed power consumption of the vehicle in the current operating mode" described in the embodiment of the present invention), thereby achieving rapid prediction of the available time of the vehicle.

[0047] In this embodiment, the total power consumption of the vehicle in the current operating mode can be calculated based on the variable power consumption and fixed power consumption of the vehicle in the current operating mode, and then the available time of the vehicle can be predicted based on the current available energy of the vehicle and the total power consumption. The available time described in the embodiment of the present invention refers to the maximum time the vehicle can run in the current operating mode.

[0048] In addition, based on the above description, this embodiment can also take "the current operating mode is the camping mode" as an example to describe in detail the problems solved by the embodiment of the present invention and the means adopted:

[0049] For example, in order to improve the user experience, many vehicles are equipped with a camping mode. When the camping mode is turned on, users can camp in the car. When the camping mode is turned on, the vehicle energy consumption will naturally increase in order to ensure a comfortable environment in the car. On this basis, it is very important to effectively evaluate the vehicle energy consumption and then predict the available time of the vehicle in the camping mode. This helps vehicle users understand the energy status of the vehicle and plan the camping time, which is an important means to improve the user experience.

[0050] Based on this, the vehicle available time prediction method provided by the embodiment of the present invention can be adopted, that is, the current ambient temperature and the set temperature can be obtained, and the variable power consumption of the vehicle in the camping mode can be determined based on the current ambient temperature and the set temperature, and then the available time of the vehicle in the camping mode can be predicted according to the variable power consumption of the vehicle in the camping mode and the preset fixed power consumption of the vehicle in the camping mode. In other words, the power consumption of the vehicle can be effectively evaluated through the variable power consumption and the fixed power consumption, and then the available time of the vehicle for camping can be accurately predicted, so as to help the vehicle user understand the energy status of the vehicle and plan the camping time, and improve the vehicle user experience.

[0051] From the above description, it can be seen that in order to achieve accurate prediction of the available time of the vehicle, the embodiment of the present invention divides the power consumption of the vehicle into variable power consumption and fixed power consumption based on the variability of power consumption, wherein variable power consumption refers to power consumption that changes over time, and fixed power consumption refers to power consumption that is relatively stable and hardly changes over time. On this basis, the present invention determines the variable power consumption based on the current ambient temperature and the set temperature, and predicts the available time of the vehicle in combination with the variable power consumption and the preset fixed power consumption. In other words, the embodiment of the present invention takes into account the variability of power consumption, and predicts the variability through the ambient temperature and the set temperature, based on which accurate calculation of the available time of the vehicle can be achieved. That is, the embodiment of the present invention effectively evaluates the power consumption of the vehicle in the current operating mode, thereby achieving accurate prediction of the available time of the vehicle, which helps vehicle users understand the energy status of the vehicle and plan the use time of the vehicle, and can effectively improve the vehicle user experience. In a possible implementation, the variable power consumption is represented by the air-conditioning power, and the variable power consumption of the vehicle in the current operating mode is determined based on the current ambient temperature and the set temperature, including:

[0052] A pre-calibrated mapping table is obtained, wherein the mapping table is used to describe the mapping relationship between different ambient temperatures, different in-vehicle required temperatures and air conditioning powers.

[0053] Based on the current ambient temperature and the set temperature, the mapping table is queried to obtain the air conditioning power of the vehicle in the current operating mode.

[0054] In this embodiment, the variable power consumption of the vehicle in the current operating mode can be represented by the air conditioning power. In the cooling mode, the air conditioning power refers to the power of the air conditioning compressor. In the heating mode, the air conditioning power refers to the power of the heater. On this basis, the air conditioning power of the vehicle in the current operating mode can be calculated by the current ambient temperature and the set temperature, and then the total power consumption of the vehicle in the current operating mode can be determined by combining the air conditioning power with the low-voltage power in the above embodiment.

[0055] In this embodiment, the mapping relationship between the ambient temperature, the required temperature in the vehicle and the air conditioning power can be pre-calibrated by means of real vehicle tests, simulation tests, etc., to obtain a mapping table. On this basis, the air conditioning power corresponding to the current ambient temperature and the required temperature in the vehicle can be determined by querying the mapping table.

[0056] In another possible implementation, variable power consumption can also be represented by P0, where P0=max{P1, P2}, max{} represents the maximum value, P1 represents the air-conditioning power at the current moment, P2 represents the average air-conditioning power in the next N hours, and N>0.

[0057] Among them, the method for determining the average air conditioning power in the next N hours is:

[0058] The ambient temperature in the next N hours is obtained, and the mapping table in the above embodiment is queried according to the required temperature in the vehicle and the ambient temperature in the next N hours to obtain the air conditioning power in the next N hours. The average air conditioning power in the next N hours is determined according to the air conditioning power in the next N hours.

[0059] In this embodiment, taking into account the variability of ambient temperature, in order to avoid the situation in certain scenarios where "the ambient temperature changes too quickly and the vehicle's available time decreases rapidly, resulting in the user being unable to plan the vehicle's usage time in time and insufficient energy is available", the embodiment of the present invention may also consider predicting the average air-conditioning power in the next N hours based on the ambient temperature in the next N hours, and using the maximum value of the average air-conditioning power and the air-conditioning power at the current moment to represent the variable power consumption, in order to more accurately predict the variable power consumption of the vehicle, and more "conservatively" predict the vehicle's available time, to avoid the situation where insufficient energy is available.

[0060] In a possible implementation, the mapping table is queried based on the current ambient temperature and the set temperature to obtain the air conditioning power of the vehicle in the current operating mode, including:

[0061] If the current ambient temperature and the set temperature are both recorded in the mapping table, the air conditioning power corresponding to the current ambient temperature and the set temperature is searched in the mapping table to obtain the air conditioning power of the vehicle in the current operating mode.

[0062] If there is a current query temperature that is not recorded in the mapping table, the air conditioning power corresponding to the adjacent temperature of the current query temperature is searched in the mapping table, and the air conditioning power of the vehicle in the current operating mode is determined based on the air conditioning power corresponding to the adjacent temperature. The current query temperature is the current ambient temperature or the set temperature.

[0063] Considering that it is impossible to record all ambient temperatures or in-vehicle required temperatures in the mapping table, an embodiment of the present invention provides a method for determining air conditioning power based on a mapping table. That is, when the current ambient temperature and the set temperature are recorded in the mapping table, the air conditioning power corresponding to the current ambient temperature and the set temperature is directly determined by looking up the table. When the current query temperature is not recorded in the mapping table, the air conditioning power corresponding to the current ambient temperature and the set temperature is determined by the air conditioning power corresponding to the adjacent temperature of the current query temperature in the mapping table.

[0064] Among them, "the current query temperature is not recorded in the mapping table" includes three situations:

[0065] In the first case, only the current ambient temperature is not recorded in the mapping table.

[0066] If the current ambient temperature is not recorded in the mapping table, the adjacent temperature of the current ambient temperature can be searched in the mapping table to obtain the first adjacent temperature and the second adjacent temperature. The air conditioning power corresponding to the first adjacent temperature and the set temperature is queried from the mapping table to obtain the first air conditioning power. The air conditioning power corresponding to the second adjacent temperature and the set temperature is queried from the mapping table to obtain the second air conditioning power. The air conditioning power corresponding to the current ambient temperature and the set temperature is determined based on the first air conditioning power and the second air conditioning power, that is, the air conditioning power of the vehicle in the current operating mode is determined.

[0067] The first adjacent temperature refers to the adjacent temperature of the current ambient temperature that is “less than the current ambient temperature” in the mapping table, and the second adjacent temperature refers to the adjacent temperature of the current ambient temperature that is “greater than the current ambient temperature” in the mapping table.

[0068] The air conditioning power corresponding to the current ambient temperature and the set temperature is determined based on the first air conditioning power and the second air conditioning power, which can be described in detail as follows:

[0069] The average of the first air conditioning power and the second air conditioning power is determined as the air conditioning power corresponding to the current ambient temperature and the set temperature.

[0070] Alternatively, Calculate the air conditioning power corresponding to the current ambient temperature and the set temperature.

[0071] Among them, P0 is the air conditioning power corresponding to the current ambient temperature and the set temperature, T0 is the current ambient temperature, T1 is the first adjacent temperature, T2 is the second adjacent temperature, P1 is the first air conditioning power, and P2 is the second air conditioning power.

[0072] In the second case, only the set temperature is not recorded in the mapping table.

[0073] If the set temperature is not recorded in the mapping table, the adjacent temperatures of the set temperature can be searched in the mapping table to obtain the third adjacent temperature and the fourth adjacent temperature. The air conditioning power corresponding to the third adjacent temperature and the current ambient temperature is queried from the mapping table to obtain the third air conditioning power. The air conditioning power corresponding to the fourth adjacent temperature and the current ambient temperature is queried from the mapping table to obtain the fourth air conditioning power. The air conditioning power corresponding to the current ambient temperature and the set temperature is determined based on the third air conditioning power and the fourth air conditioning power, that is, the air conditioning power of the vehicle in the current operating mode is determined.

[0074] The third adjacent temperature refers to a temperature adjacent to the set temperature that is “less than the set temperature” in the mapping table, and the fourth adjacent temperature refers to a temperature adjacent to the set temperature that is “greater than the set temperature” in the mapping table.

[0075] The air conditioning power corresponding to the current ambient temperature and the set temperature is determined based on the third air conditioning power and the fourth air conditioning power, which can be described in detail as follows:

[0076] An average value of the third air-conditioning power and the fourth air-conditioning power is determined as the air-conditioning power corresponding to the current ambient temperature and the set temperature.

[0077] Alternatively, Calculate the air conditioning power corresponding to the current ambient temperature and the set temperature.

[0078] Among them, P0 is the air conditioning power corresponding to the current ambient temperature and the set temperature, Ts is the set temperature, T3 is the third adjacent temperature, T4 is the fourth adjacent temperature, P3 is the third air conditioning power, and P4 is the fourth air conditioning power.

[0079] In the third case, neither the current ambient temperature nor the set temperature is recorded in the mapping table.

[0080] If the current ambient temperature and the set temperature are not recorded in the mapping table, the first adjacent temperature, the second adjacent temperature, the third adjacent temperature and the fourth adjacent temperature are determined in sequence according to the methods of the first and second situations described above. The air conditioning power corresponding to the first adjacent temperature and the third adjacent temperature is queried from the mapping table to obtain the fifth air conditioning power. The air conditioning power corresponding to the second adjacent temperature and the fourth adjacent temperature is queried from the mapping table to obtain the sixth air conditioning power. The air conditioning power corresponding to the first adjacent temperature and the fourth adjacent temperature is queried from the mapping table to obtain the seventh air conditioning power. The air conditioning power corresponding to the second adjacent temperature and the third adjacent temperature is queried from the mapping table to obtain the eighth air conditioning power. The air conditioning power corresponding to the current ambient temperature and the set temperature is determined based on the fifth air conditioning power, the sixth air conditioning power, the seventh air conditioning power and the eighth air conditioning power.

[0081] The air conditioning power corresponding to the current ambient temperature and the set temperature is determined based on the fifth air conditioning power, the sixth air conditioning power, the seventh air conditioning power, and the eighth air conditioning power, which can be described in detail as follows:

[0082] An average value of the fifth air-conditioning power, the sixth air-conditioning power, the seventh air-conditioning power and the eighth air-conditioning power is determined as the air-conditioning power corresponding to the current ambient temperature and the set temperature.

[0083] In a possible implementation, predicting the available time of the vehicle according to the variable power consumption and the preset fixed power consumption of the vehicle in the current operating mode includes:

[0084] The total power consumption of the vehicle in the current operating mode is determined according to the variable power consumption and the preset fixed power consumption of the vehicle in the current operating mode.

[0085] The current available energy of the vehicle is obtained, and the available time of the vehicle is predicted based on the current available energy and the total power consumption.

[0086] In this embodiment, the sum of the variable power consumption and the fixed power consumption is the total power consumption of the vehicle in the current operating mode.

[0087] In this embodiment, the current available energy of the vehicle refers to the energy that can still be used in the vehicle. On this basis, the ratio of the current available energy to the total power consumption is the available time of the vehicle.

[0088] In a possible implementation, before obtaining the current available energy of the vehicle, the vehicle available time prediction method further includes:

[0089] Obtain the remaining power of the vehicle's power battery, the scheduled external discharge amount of the vehicle's charger, and the preset reserved power of the vehicle.

[0090] The current available energy of the vehicle is determined based on the remaining power, the scheduled external discharge amount, and the reserved power.

[0091] In this embodiment, the predetermined external discharge amount of the charger on the vehicle can be determined by the discharge power of the charger and the preset discharge time. In this embodiment, the product of the discharge power of the charger and the preset discharge time is determined as the predetermined external discharge amount of the charger.

[0092] In a possible implementation, determining the current available energy of the vehicle based on the remaining power, the predetermined external discharge amount, and the reserved power includes:

[0093] The difference between the remaining power and the predetermined external discharge amount and the reserved power is determined as the current available energy of the vehicle.

[0094] That is, the current available energy of the vehicle = the remaining power - the scheduled external discharge amount - the reserved power.

[0095] Based on the above embodiments, in a specific implementation of the present invention, a specific method for calculating the available time of a vehicle may be:

[0096] The available time of the vehicle = (remaining power - scheduled external discharge - reserved power) / (variable power consumption + fixed power consumption)

[0097] The vehicle available time prediction method provided based on the embodiment of the present invention can effectively realize the power consumption evaluation of the vehicle in the current operating mode, and then accurately predict the vehicle's available time, which helps vehicle users understand the vehicle's energy status and plan the vehicle's usage time, and can effectively improve the vehicle user's vehicle experience.

[0098] On this basis, in a possible implementation, after determining the available time of the vehicle, the vehicle available time prediction method may further include:

[0099] The available time of the vehicle is displayed, and / or the available time of the vehicle is announced at preset time intervals.

[0100] On this basis, in a possible implementation, after determining the available time of the vehicle, the vehicle available time prediction method may further include:

[0101] When the available time of the vehicle is less than the preset time, a prompt message is issued to remind the vehicle user.

[0102] Corresponding to the vehicle available time prediction method in the above embodiment, Figure 2 This is a structural block diagram of a vehicle available time prediction device provided by an embodiment of the present invention.

[0104] The set temperature is the required temperature in the vehicle set by the user.

[0105] The available time prediction module 22 is used to predict the available time of the vehicle according to the variable power consumption and the preset fixed power consumption of the vehicle in the current operation mode.

[0107] A pre-calibrated mapping table is obtained, wherein the mapping table is used to describe the mapping relationship between different ambient temperatures, different in-vehicle required temperatures and air conditioning powers.

[0109] In a possible implementation, the variable power consumption prediction module 21 is specifically configured to perform the following steps:

[0110] If the current ambient temperature and the set temperature are both recorded in the mapping table, the air conditioning power corresponding to the current ambient temperature and the set temperature is searched in the mapping table to obtain the air conditioning power of the vehicle in the current operating mode.

[0111] If there is a current query temperature that is not recorded in the mapping table, the air conditioning power corresponding to the adjacent temperature of the current query temperature is searched in the mapping table, and the air conditioning power of the vehicle in the current operating mode is determined based on the air conditioning power corresponding to the adjacent temperature.
