Furthermore, the terms "first," "second," "third," and the like in the description of the present specification and in the appended claims, are used for distinguishing between descriptions and not necessarily for indicating or implying a relative importance.
With the development of vehicle intellectualization, the air conditioner in the existing vehicle can be controlled by physical keys or virtual keys on the vehicle-mounted equipment and also can be controlled by intelligent voice, so that the convenience of a user in use is improved.
However, when the air conditioner is adjusted in the above-mentioned various ways, the temperature in the vehicle is generally affected by the change of the environment in the vehicle during the driving process of the vehicle, so that the user needs to adjust the air outlet temperature of the air conditioner several times to make the temperature in the vehicle comfortable. That is, the temperature adjustment in the vehicle is still complicated.
Based on the above, in order to automatically adjust the air outlet temperature of the air conditioner according to the outside environment of the vehicle, so that the control of the temperature in the vehicle is more accurate and stable, and the comfort of a user is improved, the embodiment of the application provides a vehicle temperature adjusting method which can be applied to the vehicle. For example, the method and the device can be applied to terminal equipment such as vehicle-mounted equipment, a vehicle body controller or a whole vehicle controller in a vehicle, and the specific type of the terminal equipment is not limited in the embodiment of the application.
Referring to fig. 1, fig. 1 shows a flowchart of an implementation of a vehicle temperature adjustment method according to an embodiment of the present application, where the method includes the following steps:
s101, acquiring first external environment information based on environment acquisition equipment on a vehicle, and determining a first temperature compensation value according to the first environment information.
In an embodiment, the first external environment information may be information having an influence on an in-vehicle temperature. The first environmental information includes, but is not limited to, information such as an external temperature of the vehicle, an external illumination intensity, weather, and the like. At this time, the environment collection device may correspond to an external temperature sensor, an illumination intensity sensor, a rainfall sensor, or an image sensor, respectively, which is not limited.
The image sensor can shoot an environment image around the vehicle, and then a preset weather identification model is adopted to carry out model processing on the environment image, so that weather information is obtained.
In this embodiment, the first external environment information may be mainly the vehicle external temperature and the external light intensity.
In an embodiment, a temperature compensation table may be pre-stored in the vehicle, where the temperature compensation table includes a plurality of first temperature compensation values corresponding to the first environmental information respectively.
For example, in the temperature compensation table, the vehicle exterior temperature may be divided into 3 temperature ranges of A1, B1, C1, etc., and the exterior illumination intensity may be divided into 3 illumination intensity ranges of A2, B2, C2, etc. At this time, a first external environment information combination formed of 9 kinds of first external environment information may be recorded in the temperature compensation table. And, each of the first external environment information combinations may correspond to a first temperature compensation value. The vehicle may determine the above-described first temperature compensation value based on matching the first external environment information acquired this time with each of the first external environment information combinations in the temperature compensation table.
In another embodiment, the vehicle may further have a temperature compensation model stored in advance, and the model may be generated by training the model based on the external environment information and the corresponding calibration temperature compensation value in advance. At this time, the vehicle may input first external environment information into the temperature compensation model to obtain a first temperature compensation value.
In this embodiment, the method for obtaining the first temperature compensation value is not limited.
However, it should be noted that, if the first temperature compensation value is generated based only on the first external environment information, the accuracy of the generated first temperature compensation value depends on the device accuracy of the environment acquisition device. If the environment acquisition equipment is wrong or the numerical error is larger, the first temperature compensation value and the actual temperature compensation value are larger in phase difference. Further, the deviation of the target air outlet temperature obtained based on the first temperature compensation value is large, so that the temperature in the vehicle cannot tend to the set temperature of the user.
For example, in a weather where the intensity of sunlight is high and the temperature is high in summer, if the vehicle travels from the outside to the underground garage, the first external environment information collected by the environment collecting device will be information such as no sunlight and low temperature in a short time. At this time, the first temperature compensation value generated based on the first external environment information at this time will be greatly different from the first temperature compensation value generated last time. That is, the first temperature compensation value will normally become instantaneously large, and the target outlet air temperature adjusted based on the instantaneously large first temperature compensation value will also rise. Further, the temperature in the vehicle is high in summer hot weather. However, this adjustment is clearly not very practical.
Based on this, in order to correct the deviation of the first temperature compensation value generated by the environmental mutation in the occasional case, the fault tolerance of the compensation setting temperature generated later is improved, and in this embodiment, the second external environmental information is acquired through the following step S102, and the second temperature compensation value is generated. The details are as follows:
s102, acquiring second external environment information of the position of the vehicle from cloud meteorological data, and determining a second temperature compensation value according to the second external environment information.
In an embodiment, the cloud weather data may be obtained by a vehicle through a cloud weather program in the vehicle-mounted device. Typically, the weather server may transmit weather data to the cloud and may display in a cloud weather program. At this time, the vehicle may directly acquire the cloud meteorological data from the vehicle-mounted device.
In an embodiment, the second external environment information includes at least one of weather information, time and region.
The weather information includes, but is not limited to, weather, time, region, air quality and the like. The weather may be classified into cloudy days, sunny days, haze, snow days, and rainy days, which have various weather influences on the external temperature. The time may be characterized by a date and a time period. For example, the date can be divided into 4 ranges such as spring, summer, autumn and winter; the time period may be divided into: the 4 time periods from six pm to six am the next day, from six am to 10 am, from 10 am to 2 pm, and from 2 pm to 6 pm are not limited thereto. The above-mentioned region may be simply divided by regions such as the south or the north, or may be divided by each province or city, which is not limited. The air quality can be divided into 3 types of excellent, good and bad air quality. The position of the vehicle can be determined according to a positioning sensor of the vehicle, and the positioning sensor can be used for determining a region corresponding to the position of the vehicle.
In this embodiment, in order to improve the accuracy of the generated second temperature compensation value, it may be considered that the second external environment information includes the weather information, the time, and the region.
The vehicle may also store a target temperature compensation table in advance to include second temperature compensation values corresponding to a plurality of second external environment information, similar to the above manner of determining the first temperature compensation value according to the first environment information; or processing the second external environment information by adopting the temperature compensation model to obtain a second temperature compensation value. In this embodiment, the method for obtaining the second temperature compensation value is not limited.
As one example, the vehicle may determine the second temperature compensation value from a preset target temperature compensation table according to the second external environment information.
For example, when the weather is divided into 5 kinds of weather including cloudy weather, sunny weather, haze weather, snowy weather, rainy weather, etc., the date is divided into 4 kinds of ranges from spring, summer, autumn and winter, the time period is divided into 4 kinds of time periods from six pm to six am, from six am to 10 am, from 10 am to 2 pm, and from 2 pm to 6 pm, etc., and the region is divided into the south and the north, 160 kinds of environmental information combinations are recorded in the target temperature compensation table, and each environmental information combination can respectively correspond to one second temperature compensation value. At this time, the vehicle may determine the above-described second temperature compensation value based on matching the second external environment information acquired this time with each combination of environment information in the target temperature compensation table.
As an example, the vehicle may consider the outside temperature to be generally higher when the weather is sunny, the day is summer, the time period is 10 a.m. to 2 a.m. and the region is south. Therefore, compensation for the user's set temperature is often required. For example, the second temperature compensation value may be-0.5 ℃. At this time, the set temperature will further decrease, and then, when the air conditioner carries out the air-out based on the set temperature after the compensation, its air-out temperature will be lower, improves user's comfort level.
In another embodiment, in order to improve the rationality of the second temperature compensation value corresponding to each second environmental information combination in the target compensation temperature table, the vehicle may first acquire the initial temperature compensation table. And then, respectively carrying out an environmental bin test on the compensation value corresponding to each second external environmental information to obtain a calibrated temperature compensation table. And finally, storing the calibration temperature compensation table to a vehicle for external environment test, and adjusting each compensation value in the calibration temperature compensation table based on the test result to obtain the target temperature compensation table.
The initial temperature compensation table comprises compensation values corresponding to each type of second external environment information respectively, and the environment bin is used for simulating the environment formed by each type of second external environment information.
It should be noted that, each compensation value in the initial temperature compensation table is typically a value set empirically, and the value may deviate from the actual second compensation value. Therefore, calibration of the initial temperature compensation table is required.
The environmental chamber may be considered an environment in which a vehicle in which an initial temperature compensation table is stored is tested. Typically, the various environmental information within the environmental bins is controllable. In the environmental bin, a worker can control the environmental information of the environmental bin by himself. That is, the vehicle may simulate the above-described plurality of second external environment information combinations based on the controllable environment information to adjust each of the second external environment information combinations based on the comfort results of the test feedback, resulting in the calibrated temperature compensation table.
The external environment test is as follows: the temperature is preset by a tester, and the vehicle is controlled to run on an actual road. And then, the vehicle determines a corresponding temperature compensation value according to the actual external environment information and the calibration temperature compensation table so as to compensate the set temperature to obtain a compensated set temperature, and adjusts the air outlet temperature of the air conditioner based on the compensated set temperature. And then, under the adjusted air outlet temperature, feeding back a comfort result by a tester, and determining a second external environment information combination which is the same as external environment information in the real vehicle environment test process in the calibration temperature compensation table. And finally, adjusting the temperature compensation value corresponding to the same second external environment information combination based on the comfort result to obtain a target temperature compensation table. For example, the temperature compensation value in the calibration temperature compensation table is adjusted up or down.
It should be noted that, by adopting the above steps to perform the secondary calibration adjustment processing on the initial temperature compensation table, the second temperature compensation value corresponding to each second external environment combination in the finally obtained target temperature compensation table can be more reasonable.
S103, compensating according to the first temperature compensation value, the second temperature compensation value and the preset set temperature to obtain a compensated set temperature.
In an embodiment, the set temperature may be a temperature set by a user, or may be a temperature when the vehicle detects that the air conditioner is turned on and uses a temperature when the air conditioner is turned off last time as the set temperature, so as to further realize automatic control of the air conditioner. In the present embodiment, the manner of obtaining the set temperature is not limited thereto.
As one example, the vehicle may sum the first temperature compensation value, the second temperature compensation value, and the set temperature to obtain the compensated set temperature. Furthermore, the first temperature compensation value and the second temperature compensation value which are respectively generated by the external environment information are obtained in different modes to compensate the set temperature, so that the final obtained compensated set temperature is more reasonable.
It should be noted that, because the environment collection device is a device on the vehicle, the first external environment information collected by the environment collection device can be considered to reflect the external environment of the vehicle more truly. But there may be a mutation in the first external environment information. And, the second external environment information obtained from the cloud meteorological data can generally reflect the external environment information of the position of the vehicle in the large environment to a certain extent. And, the second external environmental information is generally free from abrupt changes.
Based on the above, when the environment where the vehicle is located is suddenly changed, the vehicle can also determine the compensation set temperature based on the second temperature compensation value, so as to avoid deviation generated by the first temperature compensation value generated by only relying on the first external environment information acquired by the environment acquisition device, and improve the fault tolerance and accuracy of the compensation set temperature.
For example, in a weather where the intensity of sunlight is high and the temperature is high in summer, if the vehicle travels from the outside to the underground garage, the first external environment information collected by the environment collecting device will be information such as no sunlight and low temperature in a short time. At this time, the first temperature compensation value generated based on the first external environment information at this time will be greatly different from the first temperature compensation value generated last time. That is, the first temperature compensation value will generally become large.
However, the second external environment information is environment information acquired in the cloud data, which may be used to represent external environment information in a large environment where the vehicle is located. As is clear from the above description of S102, in summer, the external temperature is high, and it is generally necessary to reduce the set temperature in order to improve the user' S comfort. At this time, the determined second temperature compensation value is generally a negative value.
Further, when the first temperature compensation value and the second temperature compensation value are added, the obtained target temperature compensation value can be made lower than the first temperature compensation value. Based on this, the compensation setting temperature generated from the target temperature compensation value having a low value is also generally low in its variation amplitude. Furthermore, in the subsequent steps, when the air conditioner adjusts the air outlet temperature based on the compensation setting temperature with lower variation range, the air outlet temperature of the air conditioner cannot be greatly increased due to abrupt change of the environment where the vehicle is located, so that the comfort of a user is improved.
To sum up, in practical situations, the vehicle needs not only the first temperature compensation value generated by the first external environment information, but also the second external environment information to correct the deviation generated by the sudden environmental change in the case of accidental first external environment information, so as to improve the fault tolerance of the generated temperature compensation set temperature and reduce the error of the compensation set temperature.
In another embodiment, the vehicle may further weight the first temperature compensation value and the second temperature compensation value to obtain the target temperature compensation value. And then, adding the target temperature compensation value and the set temperature to obtain the compensated set temperature.
The weights corresponding to the first temperature compensation value and the second temperature compensation value respectively may be preset, which is not limited. For example, the weights may each be 0.5.
However, in order to avoid that the generated first temperature compensation value is unreasonable due to abrupt change of the environment in which the vehicle is located, the vehicle may also compare the currently generated first temperature compensation value with the last generated first temperature compensation value. If the difference between the currently generated first temperature compensation value and the last generated first temperature compensation value is larger than the preset value, the environment where the vehicle is located can be considered to have abrupt change, and the currently generated first temperature compensation value is considered to have larger deviation.
Based on this, in order to reduce the deviation, the weight corresponding to the first temperature compensation value may be reduced, and the weight corresponding to the second temperature compensation value may be increased at the same time, and then the first temperature compensation value and the second temperature compensation value may be weighted according to the adjusted weight, so as to obtain the target temperature compensation value. And finally, adding the target temperature compensation value and the set temperature so as to make the deviation of the obtained compensated set temperature smaller.
When the weight corresponding to the first temperature compensation value is reduced, the preset weight can be reduced on the basis of the weight originally set. And adding a weight corresponding to the second temperature compensation value, wherein the preset weight can be added on the basis of the originally set weight.
In this embodiment, the preset weight and the preset value may be set according to actual situations, which is not limited.
It should be added that when the difference between the currently generated first temperature compensation value and the last generated first temperature compensation value is smaller than or equal to the preset value, it can be considered that the environment of the vehicle is not suddenly changed. Therefore, the vehicles can maintain the weights that the vehicles originally correspond to.
S104, adjusting the air outlet temperature of the air conditioner in the vehicle to the target air outlet temperature based on the compensation set temperature.
In one embodiment, the vehicle may input the compensation setting temperature into the air conditioner to control the air conditioner to adjust the outlet air temperature to the target outlet air temperature based on the compensation setting temperature. That is, it can be considered that when the air conditioner is operated at the target outlet air temperature, the temperature in the vehicle can be set at the compensation setting temperature that allows the user to feel comfortable.
As one example, the vehicle may be provided with a predictive model that is input as the compensation setting temperature, the current outlet air temperature, and output as the target outlet air temperature and the air volume level to determine the target outlet air temperature. Or the association relation between each compensation set temperature and the target air outlet temperature can be preset, so that the target air outlet temperature of the air conditioner can be adjusted based on the compensation set temperature at the moment. In this embodiment, the manner of determining the target outlet air temperature based on the compensation setting temperature is not limited.
In this embodiment, in order to reduce the number of times of adjusting the air conditioner by the user and make the adjusted temperature in the vehicle more comfortable, the vehicle may collect external environmental information to generate a temperature compensation value, so as to compensate the preset comfortable set temperature to obtain the compensated set temperature. Thus, when the air outlet temperature of the air conditioner is adjusted to the target air outlet temperature based on the compensation set temperature, the actual temperature in the vehicle can be at the set temperature which can make the user feel comfortable under the influence of the external environment. In addition, in order to adapt to the change of the vehicle exterior environment in the driving process, more accurate compensation set temperature is generated. In generating the temperature compensation value, the vehicle acquires first external environment information not only based on an environment acquisition device on the vehicle to generate the first temperature compensation value. Meanwhile, a second temperature compensation value can be generated according to second external environment information of the position of the vehicle, which is acquired from cloud meteorological data. Based on the information, the external environment information of the vehicle is acquired in a multi-dimensional mode to generate the first temperature compensation value and the second temperature compensation value respectively, so that the vehicle can obtain more accurate compensation set temperature when the set temperature is compensated based on the first temperature compensation value and the second temperature compensation value. Finally, the air outlet temperature of the vehicle air conditioner is regulated to the target air outlet temperature based on the accurate compensation set temperature, so that the actual temperature in the vehicle is still at the set temperature which enables a user to feel comfortable under the influence of the external environment after the air conditioner works at the target air outlet temperature. Furthermore, the control of the temperature in the vehicle can be more accurate and stable on the basis of automatically adjusting the air outlet temperature of the air conditioner, and the comfort of a user is improved.
In another embodiment, in order to ensure the real-time performance and accuracy of the target outlet air temperature of the air conditioner output, the vehicle may also predict the actual temperature in the vehicle based on the outlet air temperature. And then, adjusting the air outlet temperature to the target air outlet temperature according to the compensation set temperature and the actual temperature.
For example, the vehicle may calculate a temperature difference between the compensation set temperature and the actual temperature, and calculate the outlet air temperature adjustment amount according to the temperature difference. And then, adjusting the air outlet temperature to the target air outlet temperature according to the air outlet temperature adjustment quantity.
In an embodiment, an in-vehicle temperature prediction model may be stored in the vehicle to predict an actual temperature based on an outlet air temperature of the air conditioner. The vehicle can determine the wind temperature through the air conditioner, and can also collect according to a temperature sensor arranged at an air outlet of the air conditioner, which is not limited. In this embodiment, the vehicle may determine the wind temperature through the air conditioner to reduce hardware facilities to be installed.
In another embodiment, a plurality of temperature sensors may be provided in the vehicle to accurately determine the actual temperature in the vehicle. However, providing multiple temperature sensors will also increase hardware facilities within the vehicle. I.e. increase hardware costs. Therefore, in this embodiment, the actual temperature is obtained by predicting the air outlet temperature through software.
It will be appreciated that in order to improve user comfort, the actual temperature within the vehicle needs to reach the compensated set temperature, and therefore the vehicle needs to adjust the outlet air temperature at that time based on the difference between the actual temperature and the compensated set temperature.
As an example, after obtaining the temperature difference value, the product of the temperature difference value and the preset adjustment proportion may be calculated to obtain the temperature adjustment amount; or calculating the derivative of the temperature difference value, and multiplying the derivative by a constant (a value greater than 0) to obtain the temperature adjustment amount. In the present embodiment, the calculation method of the temperature adjustment amount is not limited.
Based on the above description, after the comfortable compensation set temperature is obtained, there may be a cause of the air conditioner itself, so that when the air conditioner works based on the air outlet temperature, a certain difference exists between the actual temperature in the vehicle and the compensation set temperature. Based on this, in order to make the actual temperature in the vehicle tend to compensate for the set temperature, the vehicle may determine an outlet air temperature adjustment amount by which the outlet air temperature is adjusted based on the above-described temperature difference value to adjust the current outlet air temperature to the target outlet air temperature.
Specifically, referring to fig. 2, fig. 2 is a flowchart illustrating a method for adjusting a vehicle temperature according to another embodiment of the present application.
