Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, and in particular to an air outlet temperature control method and device, a computing device, and a computer readable storage medium. BACKGROUND

[0002] With the continuous development of the automobile industry, consumers have increasingly high requirements for the comfort of automobiles. The temperature in the vehicle is an important factor affecting the user's driving experience.

[0003] At present, the air outlet equipment of an automobile generally blows air according to the cabin set temperature. During the driving of the automobile, the outside environment and the vehicle speed can both affect the temperature in the vehicle, so that it is difficult to maintain a comfortable environment in the vehicle by blowing air according to the cabin set temperature only, and the occupants may feel that the cabin temperature is too cold or too hot. SUMMARY

[0004] In view of the above, it is necessary to provide an air outlet temperature control method and device, a computing device, and a computer readable storage medium, which can adaptively adjust the air outlet temperature in combination with the outside environment of the cabin.

[0005] In a first aspect, the present application provides an air outlet temperature control method applied to a vehicle, the vehicle comprising air outlet equipment, the air outlet temperature control method comprising: obtaining vehicle state data and cabin inside and outside environment data, the vehicle state data comprising a first vehicle speed, and the cabin inside and outside environment data comprising a first cabin outside temperature and a cabin set temperature; determining an outside temperature compensation coefficient corresponding to the first cabin outside temperature based on the first vehicle speed and the first cabin outside temperature; determining an air outlet temperature based on the outside temperature compensation coefficient, the first cabin outside temperature, and the cabin set temperature; and controlling the air outlet equipment to blow air according to the air outlet temperature.

[0006] The above technical solution can automatically adjust the outside temperature coefficient according to the cabin outside temperature and the vehicle speed, so as to compensate for the air outlet temperature in different situations of the cabin outside temperature and the vehicle speed, reduce the phenomenon of the cabin being too hot or too cold, and improve the user's driving experience.

[0007] In a possible implementation manner, the determination of the outside temperature coefficient corresponding to the first cabin outside temperature based on the first vehicle speed and the first cabin outside temperature comprises: determining a vehicle speed interval corresponding to the first vehicle speed, and determining a temperature interval corresponding to the first cabin outside temperature; and determining the outside temperature coefficient corresponding to the first cabin outside temperature based on the vehicle speed interval, the temperature interval, and a preset outside temperature coefficient table, the outside temperature coefficient table comprising a plurality of coefficient mapping pairs, one element of each coefficient mapping pair being an outside temperature coefficient, and the other element being a combination of a vehicle speed interval and a temperature interval.

[0008] By means of the above technical solution, the influence of the temperature fluctuation and the vehicle speed fluctuation on the outside temperature coefficient can be reduced by pre-constructing the mapping relationship between the combination of the vehicle speed interval and the outside temperature interval and the outside temperature coefficient, so that the outside temperature coefficient can be determined more accurately.

[0009] In a possible implementation, the first vehicle speed is a vehicle speed collected at a first time, and the vehicle speed interval corresponding to the first vehicle speed is determined by determining the vehicle speed interval corresponding to the first vehicle speed based on the first vehicle speed and a second vehicle speed collected at a second time, the second time being a time before the first time; the first outside cabin temperature is a temperature collected at the first time, and the temperature interval corresponding to the first outside cabin temperature is determined by determining the temperature interval corresponding to the first outside cabin temperature based on the first outside cabin temperature and a second outside cabin temperature collected at a third time, the third time being a time before the first time.

[0010] By means of the above technical solution, the temperature interval corresponding to the outside cabin temperature and the vehicle speed interval corresponding to the vehicle speed are determined by means of the interval hysteresis, so that the temperature interval can cover the whole temperature range, the vehicle speed interval can cover the whole vehicle speed range, and the influence of the fluctuation of the temperature interval (for example, slight temperature change, so that the temperature before and after the change is in different temperature intervals) and the fluctuation of the vehicle speed interval (for example, slight vehicle speed change, so that the vehicle speed before and after the change is in different vehicle speed intervals) on the outside temperature coefficient can be avoided, so that the outside temperature coefficient can be accurately determined.

[0011] In a possible implementation, the inside and outside environment data of the cabin further include an inside cabin temperature and a sunlight intensity, and the outflow temperature is determined based on the outside temperature coefficient, the first outside cabin temperature, and the cabin set temperature, including: the outflow temperature is determined based on the outside temperature coefficient, the first outside cabin temperature, the cabin set temperature, the inside cabin temperature, and the sunlight intensity.

[0012] By means of the above technical solution, the outside temperature coefficient can be automatically adjusted according to the outside cabin temperature and the vehicle speed, different compensation of the outflow temperature can be realized under different outside cabin temperature and vehicle speed, and in the process of determining the outflow temperature, the influence of the current temperature and the sunlight intensity in the cabin is also considered, so that the stability of the inside cabin temperature can be maintained, the cabin can be prevented from being too cold or too hot to the greatest extent, and the driving experience of the user can be improved.

[0013] In a possible implementation, the outflow temperature is determined based on the outside temperature coefficient, the first outside cabin temperature, the cabin set temperature, the inside cabin temperature, and the sunlight intensity, including: a sunlight coefficient is determined based on the first outside cabin temperature and the sunlight intensity; and the outflow temperature is determined based on the outside temperature coefficient, the first outside cabin temperature, the cabin set temperature, the inside cabin temperature, the sunlight intensity, and the sunlight coefficient.

[0014] By adopting the technical scheme, since different sunlight intensities have different influences on the temperature in the cabin under different external temperatures, the sunlight coefficient is introduced to realize targeted compensation of the influences of different sunlight intensities on the temperature in the cabin under different external temperatures, to realize more accurate maintenance of the stability of the temperature in the cabin, to avoid the cabin from being too cold or too hot to the greatest extent, and to improve the driving experience of the user.

[0015] In a possible implementation manner, the temperature in the cabin is determined based on the temperature acquisition value in the cabin and a preset internal temperature coefficient, and the cabin set temperature is determined based on the temperature set value in the cabin and a preset set temperature coefficient.

[0016] By adopting the technical scheme, the coefficients corresponding to the temperature acquisition value in the cabin and the temperature set value in the cabin are configured, the temperature acquisition value in the cabin and the temperature set value in the cabin are normalized, and the air outlet temperature is calculated by substituting the preset air outlet temperature calculation formula.

[0017] In a possible implementation manner, after the air outlet temperature is determined, the air outlet temperature control method further includes: determining a temperature compensation value based on the first external temperature of the cabin and the cabin set temperature; correcting the air outlet temperature based on the temperature compensation value; and controlling the air outlet device to blow air according to the air outlet temperature, including: controlling the air outlet device to blow air according to the corrected air outlet temperature.

[0018] By adopting the technical scheme, different combinations of the external temperature of the cabin and the cabin set temperature are set to correspond to different temperature compensation values, so as to realize different compensation of the air outlet temperature and to further reduce the phenomenon that the cabin is too cold or too hot.

[0019] In a second aspect, the application provides an air outlet temperature control device applied to a vehicle, the vehicle including an air outlet device, the air outlet temperature control device including: an acquisition module configured to acquire vehicle state data and cabin internal and external environment data, the vehicle state data including a first vehicle speed, and the cabin internal and external environment data including a first external temperature of the cabin and a cabin set temperature; a first determination module configured to determine an external temperature coefficient corresponding to the first external temperature of the cabin based on the first vehicle speed and the first external temperature of the cabin; a second determination module configured to determine an air outlet temperature based on the external temperature coefficient, the first external temperature of the cabin and the cabin set temperature; and a control module configured to control the air outlet device to blow air according to the air outlet temperature.

[0020] By adopting the technical scheme, the external temperature coefficient can be automatically adjusted according to the external temperature of the cabin and the vehicle speed, so as to realize different compensation of the air outlet temperature under different external temperatures of the cabin and vehicle speeds, to reduce the phenomenon that the cabin is too cold or too hot, and to improve the driving experience of the user.

[0032] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0035] In-vehicle temperature is a crucial factor affecting the user's driving experience. Currently, car air vents generally operate based on the cabin's set temperature. However, during driving, the external environment and vehicle speed change unpredictably. Since both external environment and vehicle speed can affect the in-vehicle temperature, it becomes difficult for the air vents to maintain a comfortable environment by only distributing air according to the cabin's set temperature. Passengers may find the in-vehicle temperature too cold or too hot.

[0036] Therefore, this application provides an air outlet temperature control method that can adaptively adjust the air outlet temperature based on the internal and external environment of the cabin, thereby improving the user's driving experience.

[0037] like Figure 1 The illustration shows a possible application scenario provided by an embodiment of this application, which includes a vehicle 100. The vehicle 100 may include a sensing system 110, a display device 120, peripheral devices 130, and a computing device 140.

[0038] The perception system 110 can include several sensors for sensing information about the inside and outside of the vehicle 100. For example, the perception system 110 can include one or more of environmental sensors (e.g., sensors for monitoring information such as temperature, humidity, light intensity, etc.), a vehicle speed sensor, an inertial measurement unit (IMU), a positioning system, a radar system, an acoustic sensor, and a camera. The display device 120 can include an in-vehicle display screen, such as a digital instrument display screen, a center screen, etc. The peripheral device 130 is used for voice interaction with the user, and the peripheral device 130 can include a sound receiving device, such as a microphone, for receiving audio (e.g., voice commands or other audio input) from a user of the vehicle 100, and a sound outputting device, such as a speaker, for outputting audio to a user of the vehicle 100. In some possible implementations, the vehicle 100 can also interact with the user through other peripheral devices, such as a Bluetooth headset, etc., and the embodiments of the present application do not make specific limitations thereto.

[0039] Some or all functions of the vehicle 100 can be controlled by the computing device 140. The computing device 140 can include a processor or a circuit / chip with signal processing capability. The processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU), or a digital signal processor (DSP), etc. The processor can also be a hardware circuit that implements certain functions through a fixed or reconfigurable logical relationship, such as an application-specific integrated circuit (ASIC) or a programmable logic device (PLD) implemented hardware circuit, such as a field programmable gate array (FPGA). In addition, the processor can also be a hardware circuit designed for artificial intelligence, which can be understood as a kind of ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing device 140 can also include a memory for storing instructions, and the processor can call the instructions in the memory and execute the instructions to implement corresponding functions.

[0040] Referring to Figure 2 , Figure 2 A flowchart of an air outlet temperature control method provided by an embodiment of the present application is shown. The air outlet temperature control method can be applied to the computing device described above. The air outlet temperature control method can include the following steps.

[0041] S201, vehicle state data and cabin inside and outside environment data are acquired. The vehicle state data includes a first vehicle speed of the vehicle. The cabin inside and outside environment data includes a first cabin outside temperature and a cabin set temperature.

[0042] In some embodiments, the vehicle state data can refer to data for representing whether the vehicle is currently started and the vehicle speed. The embodiment of the present application takes the first vehicle speed of the vehicle as an example for illustration. The first vehicle speed can refer to the vehicle speed collected under the condition of triggering the execution of the air outlet temperature control method. For example, the computing device can communicate with the vehicle-deployed vehicle speed sensor to acquire the first vehicle speed.

[0043] The cabin inside and outside environment data can refer to data for representing the cabin inside and outside environment information. For example, the cabin inside and outside environment data can include the cabin inside and outside temperature, the cabin set temperature, the cabin outside sunlight intensity, etc. The embodiment of the present application takes the first cabin outside temperature and the cabin set temperature as an example for illustration. The first cabin outside temperature can refer to the temperature outside the cabin collected under the condition of triggering the execution of the air outlet temperature control method. For example, the computing device can communicate with the vehicle-deployed temperature sensor for sensing the temperature outside the cabin to acquire the first cabin outside temperature. The cabin set temperature can also refer to the temperature currently set in the cabin collected under the condition of triggering the execution of the air outlet temperature control method. For example, the temperature set by the user manually / voice command or the temperature set automatically by the cabin system. The computing device can communicate with the cabin system to acquire the cabin set temperature.

[0044] For another example, the execution of the air outlet temperature control method can be triggered when the cabin set temperature changes, or triggered every preset time. The preset time can be set according to actual needs, which is not limited in the embodiment of the present application.

[0045] S202, based on the first vehicle speed and the first cabin outside temperature, an outside temperature coefficient corresponding to the first cabin outside temperature is determined.

[0046] In some embodiments, a mapping relationship between combinations of vehicle speed and outside cabin temperature and outside temperature coefficients can be pre-constructed, so that the computing device can obtain, based on the mapping relationship, an outside temperature coefficient for compensating the first outside cabin temperature at the first vehicle speed and the first outside cabin temperature. For example, an outside temperature coefficient table can be pre-constructed, and the outside temperature coefficient table includes a plurality of coefficient mapping pairs, and each coefficient mapping pair includes an outside temperature coefficient and a combination of vehicle speed and outside temperature.

[0047] Compared with the prior art, in which a fixed outside temperature coefficient is used to compensate the air outlet temperature under different outside temperatures and vehicle speeds, the fixed outside temperature coefficient can cause a large deviation in the compensation amount of the air outlet temperature due to different outside temperatures and vehicle speeds, which can easily lead to poor followability of the air volume and the air outlet temperature, and the temperature in the vehicle can change from comfortable to cold or hot after the vehicle speed is increased or decreased, which affects the driving experience of the user. The embodiments of the present application can dynamically set the outside temperature coefficient according to different outside temperatures and vehicle speeds, so that the compensation amount of the air outlet temperature calculated subsequently can maintain the stability and comfort of the temperature in the vehicle, and improve the driving experience of the user.

[0048] In some embodiments, during the driving of the vehicle, the outside environment and the vehicle speed have fluctuation characteristics, in order to more accurately determine the outside temperature coefficient, a mapping relationship between combinations of vehicle speed intervals and outside cabin temperature intervals and outside temperature coefficients can also be pre-constructed to reduce the influence of outside temperature fluctuations and vehicle speed fluctuations on the outside temperature coefficient. For example, for each coefficient mapping pair in the outside temperature coefficient table, one element of the coefficient mapping pair is an outside temperature coefficient, and the other element is a combination of a vehicle speed interval and a temperature interval.

[0049] Specifically, determining the outside temperature coefficient corresponding to the first outside cabin temperature based on the first vehicle speed and the first outside cabin temperature can include: determining a vehicle speed interval corresponding to the first vehicle speed, and determining a temperature interval corresponding to the first outside cabin temperature; and determining the outside temperature coefficient corresponding to the first outside cabin temperature based on the vehicle speed interval, the temperature interval, and a pre-set outside temperature coefficient table. For example, the outside cabin temperature can be divided into a plurality of temperature intervals, and each temperature interval can correspond to a temperature range. The vehicle speed can be divided into a plurality of vehicle speed intervals, and each vehicle speed interval can correspond to a vehicle speed range. For another example, the temperature intervals can include, from high to low, ultrahigh temperature, high temperature, normal temperature, low temperature, and ultralow temperature, and the vehicle speed intervals can include, from high to low, high speed, medium-high speed, medium speed, low speed, and idle speed.

[0050] In some embodiments, in order to enable the temperature intervals to cover the entire temperature range, the vehicle speed intervals to cover the entire vehicle speed range, and to avoid the influence of fluctuations in the temperature intervals (e.g., slight temperature changes, which cause the temperature before and after the change to be in different temperature intervals) and fluctuations in the vehicle speed intervals (e.g., slight vehicle speed changes, which cause the vehicle speed before and after the change to be in different vehicle speed intervals) on the outside temperature coefficient, so as to accurately determine the outside temperature coefficient.

[0051] Specifically, determining the vehicle speed interval corresponding to the first vehicle speed can further include: determining the vehicle speed interval corresponding to the first vehicle speed based on the first vehicle speed and a second vehicle speed collected at a second time. The first vehicle speed is a vehicle speed collected at a first time, and the second time is a time before the first time. The time interval between the second time and the first time can be set according to actual needs, and the embodiments of the present application do not limit this. The second time can be set to one or more, and the first vehicle speed collected at the first time and the second vehicle speed collected at the second time are used to evaluate whether the vehicle speed is in the rising period or the falling period. That is, to evaluate whether the vehicle speed is falling to the first vehicle speed or rising to the first vehicle speed, so as to accurately determine the vehicle speed interval corresponding to the first vehicle speed.

[0052] As shown in Figure 3 The vehicle speed interval can include high speed, medium-high speed, medium speed, low speed, and idle speed. Vehicle speed > 100 km / h is defined as high speed; during the vehicle speed rising period, vehicle speed in 85-100 km / h is defined as high speed. Vehicle speed in 80-85 km / h is defined as medium-high speed; during the vehicle speed falling period, vehicle speed in 85-100 km / h is defined as medium-high speed; during the vehicle speed rising period, vehicle speed in 65-80 km / h is defined as medium-high speed. Vehicle speed in 60-65 km / h is defined as medium speed; during the vehicle speed falling period, vehicle speed in 65-80 km / h is defined as medium speed; during the vehicle speed rising period, vehicle speed in 45-60 km / h is defined as medium speed. Vehicle speed in 40-45 km / h is defined as low speed; during the vehicle speed falling period, vehicle speed in 45-60 km / h is defined as low speed; during the vehicle speed rising period, vehicle speed in 20-40 km / h is defined as low speed. Vehicle speed < 20 km / h is defined as idle speed; during the vehicle speed falling period, vehicle speed in 20-40 km / h is defined as idle speed.

[0053] In some embodiments, it can also be set that when the collected first vehicle speed falls into the vehicle speed hysteresis interval, the determination of the vehicle speed interval corresponding to the first vehicle speed based on the first vehicle speed and the second vehicle speed collected at the second time is triggered. When the collected first vehicle speed does not fall into the vehicle speed hysteresis interval, the vehicle speed interval corresponding to the first vehicle speed is directly determined based on the first vehicle speed. The vehicle speed hysteresis interval can refer to a vehicle speed interval with different divisions during the rising period and the falling period, for example, the vehicle speed hysteresis interval includes 85-100 km / h, 65-80 km / h, 45-60 km / h, and 20-40 km / h.

[0054] In some embodiments, for the special state of uniform speed driving, 85-100 km / h can also be defined as medium-high speed, 65-80 km / h can be defined as medium speed, and 45-60 km / h and 20-40 km / h can be defined as low speed.

[0055] In some embodiments, determining the temperature interval corresponding to the first outside-cabin temperature can further include: determining the temperature interval corresponding to the first outside-cabin temperature based on the first outside-cabin temperature and a second outside-cabin temperature collected at a third time. The first outside-cabin temperature is an outside-cabin temperature collected at a first time, and the third time is a time before the first time. The time interval between the third time and the first time can be set according to actual needs, and the embodiments of the present application do not limit this. The third time can be set to one or more, and based on the first outside-cabin temperature collected at the first time and the second outside-cabin temperature collected at the third time, it is determined whether the temperature is in the rising period or the falling period. That is, it is determined whether the temperature falls to the first outside-cabin temperature or rises to the first outside-cabin temperature, so as to accurately determine the temperature interval corresponding to the first outside-cabin temperature.

[0056] As shown in Figure 4 The temperature interval can include ultrahigh temperature, high temperature, normal temperature, low temperature, and ultralow temperature. The outside-cabin temperature > 40°C is defined as ultrahigh temperature; during the temperature rising period, the outside-cabin temperature in 35-40°C is defined as ultrahigh temperature. The outside-cabin temperature in 30-35°C is defined as high temperature; during the temperature falling period, the outside-cabin temperature in 35-40°C is defined as high temperature; during the temperature rising period, the outside-cabin temperature in 25-30°C is defined as high temperature. The outside-cabin temperature in 20-25°C is defined as normal temperature; during the temperature falling period, the outside-cabin temperature in 25-30°C is defined as normal temperature; during the temperature rising period, the outside-cabin temperature in 15-20°C is defined as normal temperature. The outside-cabin temperature in 0-15°C is defined as low temperature; during the temperature falling period, the outside-cabin temperature in 15-20°C is defined as low temperature; during the temperature rising period, the outside-cabin temperature in -5-0°C is defined as low temperature. The outside-cabin temperature < -5°C is defined as ultralow temperature; during the temperature falling period, the outside-cabin temperature in -5-0°C is defined as ultralow temperature.

[0057] In some embodiments, it can also be set that when the collected first outside-cabin temperature falls into the temperature hysteresis interval, the determination of the temperature interval corresponding to the first outside-cabin temperature based on the first outside-cabin temperature and the second outside-cabin temperature collected at the third time is triggered. When the collected first outside-cabin temperature does not fall into the temperature hysteresis interval, the temperature interval corresponding to the first outside-cabin temperature is directly determined based on the first outside-cabin temperature. The temperature hysteresis interval can refer to a temperature interval that has different divisions during the rising period and the falling period, for example, the temperature hysteresis interval includes 35-40°C, 25-30°C, 15-20°C, -5-0°C.

[0058] In some embodiments, for the special driving scenarios with substantially constant temperature, 35-40°C can be defined as high temperature, 25-30°C as normal temperature, 15-20°C as low temperature, and -5-0°C as ultra-low temperature.

[0059] In some embodiments, the preset outside temperature coefficient table can be shown in Table 1 as follows:

[0060]

[0061] In Table 1, each outside temperature coefficient corresponds to a combination of a vehicle speed interval and a temperature interval. For example, the outside temperature coefficient at ultra-low temperature and idle speed is 1.1, the outside temperature coefficient at ultra-low temperature and high speed is 1.36, the outside temperature coefficient at ultra-high temperature and idle speed is 1.1, and the outside temperature coefficient at ultra-high temperature and high speed is 1.28.

[0062] It can be understood that the outside temperature coefficients in Table 1 above are only an example, and can be adjusted according to the actual vehicle configuration, which is not limited in the embodiments of the present application.

[0063] For example, after the computing device obtains the first outside cabin temperature, the computing device determines the temperature interval corresponding to the first outside cabin temperature based on Figure 4 the temperature interval determination method.

[0064] a. Assuming that the computing device determines that the temperature interval corresponding to the first outside cabin temperature is ultra-low temperature, the computing device determines the vehicle speed interval corresponding to the first vehicle speed based on Figure 3 the vehicle speed interval determination method. If it is determined that the vehicle speed interval corresponding to the first vehicle speed is idle speed, the computing device can determine that the outside temperature coefficient is 1.1; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is low speed, the computing device can determine that the outside temperature coefficient is 1.2; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium speed, the computing device can determine that the outside temperature coefficient is 1.28; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium-high speed, the computing device can determine that the outside temperature coefficient is 1.32; and if it is determined that the vehicle speed interval corresponding to the first vehicle speed is high speed, the computing device can determine that the outside temperature coefficient is 1.36.

[0065] b. Assuming that the computing device determines that the temperature interval corresponding to the first outside cabin temperature is low temperature, the computing device determines the vehicle speed interval corresponding to the first vehicle speed based on Figure 3The schematic vehicle speed interval determination method determines the vehicle speed interval corresponding to the first vehicle speed. If it is determined that the vehicle speed interval corresponding to the first vehicle speed is idle speed, the computing device can determine the external temperature coefficient as -1.1; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is low speed, the computing device can determine the external temperature coefficient as -1.16; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium speed, the computing device can determine the external temperature coefficient as -1.2; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium-high speed, the computing device can determine the external temperature coefficient as -1.24; and if it is determined that the vehicle speed interval corresponding to the first vehicle speed is high speed, the computing device can determine the external temperature coefficient as -1.32.

[0066] c. If the computing device determines that the temperature interval corresponding to the first cabin external temperature is normal temperature, the computing device can directly determine the external temperature coefficient as 1.1. That is, the external temperature coefficient is not affected by the vehicle speed.

[0067] d. If the computing device determines that the temperature interval corresponding to the first cabin external temperature is high temperature, the computing device further determines the vehicle speed interval corresponding to the first vehicle speed based on the first vehicle speed, and then determines the external temperature coefficient based on the vehicle speed interval corresponding to the first vehicle speed and the first cabin external temperature. Figure 3 The schematic vehicle speed interval determination method determines the vehicle speed interval corresponding to the first vehicle speed. If it is determined that the vehicle speed interval corresponding to the first vehicle speed is idle speed, the computing device can determine the external temperature coefficient as 1.1; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is low speed, the computing device can determine the external temperature coefficient as 1.16; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium speed, the computing device can determine the external temperature coefficient as 1.2; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium-high speed, the computing device can determine the external temperature coefficient as 1.24; and if it is determined that the vehicle speed interval corresponding to the first vehicle speed is high speed, the computing device can determine the external temperature coefficient as 1.26.

[0068] e. If the computing device determines that the temperature interval corresponding to the first cabin external temperature is ultra-high temperature, the computing device further determines the vehicle speed interval corresponding to the first vehicle speed based on the first vehicle speed, and then determines the external temperature coefficient based on the vehicle speed interval corresponding to the first vehicle speed and the first cabin external temperature. Figure 3 The schematic vehicle speed interval determination method determines the vehicle speed interval corresponding to the first vehicle speed. If it is determined that the vehicle speed interval corresponding to the first vehicle speed is idle speed, the computing device can determine the external temperature coefficient as 1.1; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is low speed, the computing device can determine the external temperature coefficient as 1.19; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium speed, the computing device can determine the external temperature coefficient as 1.24; if it is determined that the vehicle speed interval corresponding to the first vehicle speed is medium-high speed, the computing device can determine the external temperature coefficient as 1.26; and if it is determined that the vehicle speed interval corresponding to the first vehicle speed is high speed, the computing device can determine the external temperature coefficient as 1.28.

[0069] It can be understood that the computing device can also first determine the vehicle speed interval corresponding to the first vehicle speed, and then determine the temperature interval corresponding to the first cabin external temperature, to determine the corresponding external temperature coefficient.

[0070] In some embodiments, when the temperature outside the cabin is at high temperature and ultra-high temperature, the air convection at high vehicle speed exchanges a large amount of heat with the cabin, the heat in the cabin will increase obviously with the increase of vehicle speed, the compensation demand of the air outlet temperature of the air conditioning refrigeration is large, in order to reduce the phenomenon that the temperature in the cabin is too high at high vehicle speed, the outside temperature coefficient can be set to increase with the increase of vehicle speed, so as to reduce the air outlet temperature with the increase of vehicle speed, and ensure that the temperature in the cabin will not be too high at high vehicle speed. When the temperature outside the cabin is at normal temperature, the temperature difference between the temperature outside the cabin and the temperature in the cabin is small, the temperature fluctuation in the cabin is small with the change of vehicle speed, the compensation demand of the air outlet temperature of the air conditioning refrigeration or the warm air system is small, the outside temperature coefficient can be set to a relatively small value, and does not change with the change of vehicle speed. When the outside temperature is at low temperature and ultra-low temperature, the heat in the cabin will decrease obviously with the increase of vehicle speed, the compensation demand of the air outlet temperature of the warm air system is large, in order to reduce the phenomenon that the temperature in the cabin is too low at high vehicle speed, in the case of low temperature, the outside temperature coefficient can be set to a negative value (low temperature is generally a positive value above 0℃), and decreases with the increase of vehicle speed, so as to increase the air outlet temperature with the increase of vehicle speed, and ensure that the temperature in the cabin will not be too low at high vehicle speed, in the case of ultra-low temperature, the outside temperature coefficient can be set to a positive value (ultra-low temperature is generally a negative value below 0℃), and increases with the increase of vehicle speed, so as to increase the air outlet temperature with the increase of vehicle speed, and ensure that the temperature in the cabin will not be too low at high vehicle speed.

[0071] In some embodiments, as shown in Table 2 below, the temperature compensation range (unit: ℃) of the air outlet temperature in different temperature intervals and vehicle speed intervals is illustrated based on the setting rule of the above-mentioned outside temperature coefficient.

[0072]

[0073] In Table 2, “-” represents that the air outlet temperature decreases to avoid the temperature in the cabin being too high, and “+” represents that the air outlet temperature increases to avoid the temperature in the cabin being too low.

[0074] It can be understood that the temperature compensation range of the air outlet temperature in Table 2 above is only an example, which can be adjusted according to the actual set outside temperature coefficient, and the embodiments of the present application are not limited thereto.

[0075] S203, determining the air outlet temperature based on the outside temperature coefficient, the first temperature outside the cabin and the cabin set temperature.

[0076] In some embodiments, after determining the outside temperature coefficient, the computing device can determine the air outlet temperature based on the outside temperature coefficient, the first outside cabin temperature and the cabin set temperature. For example, a first function for calculating the air outlet temperature based on the outside temperature coefficient, the outside cabin temperature and the cabin set temperature can be pre-constructed and stored in the computing device. The computing device can substitute the currently determined outside temperature coefficient, the first outside cabin temperature and the cabin set temperature into the first function to calculate the air outlet temperature. The specific form of the first function is not limited in the embodiments of the present application.

[0077] In S204, the computing device controls the air outlet device to blow air according to the air outlet temperature.

[0078] In some embodiments, after determining the air outlet temperature, the computing device can control the air outlet device to blow air according to the air outlet temperature. The air outlet device can be a vehicle air ventilation system, a vehicle air conditioning system or a vehicle air heating system. The vehicle air heating system can be an electric machine thermal management system or an engine thermal management system.

[0079] The air outlet temperature control method can automatically adjust the outside temperature coefficient according to the outside cabin temperature and the vehicle speed, so as to compensate the air outlet temperature in different situations of the outside cabin temperature and the vehicle speed, reduce the phenomenon of overheating or overcooling in the cabin and improve the driving experience of the user.

[0080] Please refer to Figure 5 , Figure 5 A flowchart of an air outlet temperature control method provided by another embodiment of the present application is shown. The air outlet temperature control method can be applied to the computing device described above. The air outlet temperature control method can include the following steps.

[0081] In S501, vehicle state data and cabin inside and outside environment data are acquired. The vehicle state data includes a first vehicle speed, and the cabin inside and outside environment data includes a first outside cabin temperature, a cabin set temperature, a cabin inside temperature and a sunlight intensity.

[0082] In some embodiments, the cabin inside temperature can be acquired by a temperature sensor inside the cabin. The computing device can acquire the cabin inside temperature by communicating with the temperature sensor deployed in the vehicle for sensing the cabin inside temperature. The sunlight intensity can be the sunlight intensity outside the cabin. The first vehicle speed, the first outside cabin temperature and the cabin set temperature can refer to the descriptions in the foregoing embodiments, which will not be repeated here.

[0083] In S502, an outside temperature coefficient corresponding to the first outside cabin temperature is determined based on the first vehicle speed and the first outside cabin temperature.

[0084] The step S502 of the embodiments of the present application is similar to the step S202 of the foregoing embodiments, which will not be repeated here.

[0085] S503, determining the air outlet temperature based on the outside temperature coefficient, the first outside temperature, the cabin set temperature, the inside temperature and the sunlight intensity.

[0086] In some embodiments, after determining the outside temperature coefficient, the computing device can determine the air outlet temperature based on the outside temperature coefficient, the first outside temperature, the cabin set temperature, the inside temperature and the sunlight intensity. For example, a second function for calculating the air outlet temperature based on the outside temperature coefficient, the first outside temperature, the cabin set temperature, the inside temperature and the sunlight intensity can be constructed in advance, and the second function can be stored in the computing device. The computing device can substitute the currently determined outside temperature coefficient, the first outside temperature, the cabin set temperature, the inside temperature and the sunlight intensity into the second function to calculate the air outlet temperature. The specific form of the second function is not limited in the embodiments of the present application.

[0087] In some embodiments, the sunlight intensity has different influences on the inside temperature in different outside temperature situations, and the second function can further introduce a sunlight coefficient to compensate for the influences of different sunlight intensities on the inside temperature in different outside temperature situations. That is, the second function can be further set to calculate the air outlet temperature based on the outside temperature coefficient, the first outside temperature, the cabin set temperature, the inside temperature, the sunlight intensity and the sunlight coefficient.

[0088] For example, in the case of high or super-high outside temperature, the sunlight intensity has a greater contribution to the heat in the cabin, so that the inside temperature increases significantly with the increase of the sunlight intensity, resulting in an increased compensation demand for the air outlet temperature. Therefore, a larger sunlight coefficient can be set in the case of high or super-high outside temperature. In the case of normal or low outside temperature, the sunlight intensity has a smaller contribution to the heat in the cabin, so that the inside temperature is less affected by the sunlight intensity. Therefore, a smaller sunlight coefficient can be set in the case of normal or low outside temperature. In the case of super-low outside temperature, the sunlight intensity has a smaller contribution to the heat in the cabin, so that the inside temperature is less affected by the sunlight intensity. Therefore, a smaller sunlight coefficient can be set in the case of normal or low outside temperature.

[0089] For example, a sunlight coefficient table can be constructed in advance, and the sunlight coefficient table includes a plurality of sunlight coefficient mapping pairs. One element of the sunlight coefficient mapping pair is the sunlight coefficient, and the other element is the combination of the outside temperature and the sunlight intensity, or the combination of the outside temperature interval and the sunlight intensity interval.

[0090] S504, controlling the air outlet device to outlet air according to the air outlet temperature.

[0091] The step S504 of the embodiments of the present application is similar to the step S204 of the foregoing embodiments, and will not be described here again to avoid repetition.

[0092] The air outlet temperature control method can automatically adjust the external temperature coefficient according to the external temperature of the cabin and the vehicle speed, so as to compensate the air outlet temperature in different situations of the external temperature of the cabin and the vehicle speed, and in the process of determining the air outlet temperature, the current temperature in the cabin and the sunlight intensity are also considered, so as to keep the stability of the temperature in the cabin, avoid the cabin from being too cold or too hot to the greatest extent, and improve the driving experience of the user.

[0093] Please refer to Figure 6 , Figure 6 A flowchart of an air outlet temperature control method provided by another embodiment of the application is shown. The air outlet temperature control method can be applied to the computing device described above, and the air outlet temperature control method can include the following steps.

[0094] S601, vehicle state data and cabin internal and external environment data are obtained, the vehicle state data includes a first vehicle speed, and the cabin internal and external environment data includes a first external temperature of the cabin, a cabin set temperature, a cabin internal temperature, and a sunlight intensity.

[0095] The step S601 of the embodiment of the application is similar to the step S501 of the foregoing embodiment, and will not be described here again to avoid repetition.

[0096] S602, based on the first vehicle speed and the first external temperature of the cabin, an external temperature coefficient corresponding to the first external temperature of the cabin is determined.

[0097] The step S602 of the embodiment of the application is similar to the step S202 of the foregoing embodiment, and will not be described here again to avoid repetition.

[0098] S603, based on the first external temperature of the cabin and the cabin set temperature, a temperature compensation value is determined.

[0099] In some embodiments, the temperature difference between the external temperature of the cabin and the cabin set temperature is different, and the operation pressure of the air outlet device is different. By setting different combinations of the external temperature of the cabin and the cabin set temperature, different temperature compensation values are obtained, so as to compensate the air outlet temperature, and further reduce the phenomenon that the cabin is too cold or too hot.

[0100] For example, a temperature compensation table can be constructed in advance, the temperature compensation table includes a plurality of temperature compensation mapping pairs, one element of the temperature compensation mapping pair is a temperature compensation value, and the other element is a combination of the external temperature of the cabin and the cabin set temperature, or a combination of the external temperature interval of the cabin and the cabin set temperature interval.

[0101] S604, based on the first external temperature of the cabin and the sunlight intensity, a sunlight coefficient is determined.

[0102] In some embodiments, the process of determining the sunlight coefficient can refer to the content about step S503 in the foregoing embodiments, and details are not described herein again to avoid repetition.

[0103] In some embodiments, there is no execution sequence limitation between step S602, step S603 and step S604. For example, step S602, step S603 and step S604 can be executed simultaneously, or any one of step S602, step S603 and step S604 can be executed before, between or after the other two steps.

[0104] S605, determining the air outlet temperature based on the outside temperature coefficient, the first outside cabin temperature, the temperature compensation value, the cabin set temperature, the inside cabin temperature, the sunlight intensity and the sunlight coefficient.

[0105] In some embodiments, after the outside temperature coefficient, the temperature compensation value and the sunlight coefficient are determined, the computing device can determine the air outlet temperature based on the outside temperature coefficient, the first outside cabin temperature, the temperature compensation value, the cabin set temperature, the inside cabin temperature, the sunlight intensity and the sunlight coefficient. For example, a third function for calculating the air outlet temperature based on the outside temperature coefficient, the first outside cabin temperature, the temperature compensation value, the cabin set temperature, the inside cabin temperature, the sunlight intensity and the sunlight coefficient can be constructed in advance, and the third function can be stored in the computing device. The computing device can substitute the outside temperature coefficient, the first outside cabin temperature, the temperature compensation value, the cabin set temperature, the inside cabin temperature, the sunlight intensity and the sunlight coefficient into the third function to calculate the air outlet temperature. The specific form of the third function is not limited in the embodiments of the present application.

[0106] For another example, the third function can be set as: T m outlet = T s set - T n in × W2- T h out × W3- I × W4- T w compensation.

[0107] Wherein, T m outlet is the air outlet temperature, T s set is the cabin set temperature, W1 is the set temperature coefficient, T n in is the inside cabin temperature, W2 is the inside temperature coefficient, T h out is the outside cabin temperature, W3 is the outside temperature coefficient, I is the sunlight intensity, W4 is the sunlight coefficient, and T w compensation is the temperature compensation value. The set temperature coefficient and the inside temperature coefficient can be set as constants, that is, the set temperature coefficient can not change with the change of the cabin set temperature, and the inside temperature coefficient can not change with the change of the inside cabin temperature. It can be understood that each calculation element in the third function can be normalized according to actual needs to accurately calculate the air outlet temperature.

[0108] S606 controls the air outlet equipment to output air according to the outlet temperature.

[0109] Step S606 in this embodiment is similar to step S204 in the previous embodiment, and will not be repeated here to avoid repetition.

[0110] The aforementioned air outlet temperature control method can automatically adjust the outside temperature coefficient based on the outside temperature of the cabin and the vehicle speed, so as to compensate the air outlet temperature differently under different outside temperatures and vehicle speeds. In the process of determining the air outlet temperature, the temperature compensation value is also determined based on the outside temperature of the cabin and the set cabin temperature, and the sunlight coefficient is determined based on the outside temperature of the cabin and the sunlight intensity, so as to maintain the stability of the cabin temperature more accurately and avoid the cabin from being too cold or too hot to the greatest extent, thereby improving the user's driving experience.
