Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

Fig. 1 illustrates a method for controlling a temperature of a vehicle according to an exemplary embodiment of the present disclosure, which may be applied to a vehicle, as shown in fig. 1, and includes the steps of:

s101, when an air conditioner of the vehicle is turned off, acquiring a first in-vehicle temperature of the vehicle.

The first in-vehicle temperature can be acquired through a temperature sensor arranged in the vehicle.

It should be noted that the first in-vehicle temperature may be any time between the air conditioner off time and the air conditioner re-on time, for example, the first in-vehicle temperature is the in-vehicle temperature at the air conditioner off time, or the first in-vehicle temperature is the in-vehicle temperature at the air conditioner re-on time, and it is considered that the in-vehicle temperature detected by the temperature sensor may fluctuate due to the influence of the vehicle conditions or the ambient environment as time passes after the air conditioner is turned off, and therefore, it is preferable that the embodiment may set the in-vehicle temperature at the air conditioner off time as the first in-vehicle temperature.

And S102, when the air conditioner is turned on again, acquiring the ambient temperature of the environment where the vehicle is located.

In this step, the ambient temperature of the vehicle environment may be detected by a temperature sensor disposed in the engine compartment of the vehicle.

S103, when the ambient temperature is less than or equal to the first in-vehicle temperature, acquiring a temperature compensation amount.

When the environment temperature is less than or equal to the first in-vehicle temperature, the vehicle is in a low-temperature environment.

In this step, the temperature compensation amount may be acquired by either of the following two ways:

the first method is as follows: the preset temperature compensation amount is obtained.

In this embodiment, the temperature compensation amount may be set in advance based on an empirical value.

The second method comprises the following steps: determining the closing time length of the air conditioner, determining a target time length range in which the closing time length is located from a plurality of preset time length ranges, and determining the temperature compensation amount corresponding to the target time length range according to a first preset corresponding relation, wherein the first preset corresponding relation comprises the temperature compensation amount corresponding to each time length range. By adopting the mode, the temperature compensation quantity can be flexibly determined according to the closing time of the air conditioner, and the universality of obtaining the temperature compensation quantity is improved.

For example, the temperature compensation amount corresponding to the closing time period 0-200 seconds may be 5 ℃, the temperature compensation amount corresponding to the closing time period 201-400 seconds may be 8 ℃, and the temperature compensation amount corresponding to the closing time period 401-600 seconds may be 6 ℃, which is only illustrated here and is not limited by the present disclosure.

And S104, obtaining the compensated in-vehicle temperature according to the first in-vehicle temperature and the temperature compensation amount, and controlling the air conditioner to work according to the compensated in-vehicle temperature.

In this step, after the temperature compensation amount is obtained, since the in-vehicle temperature sensor may be affected by heat radiation of the peripheral component at this time, the in-vehicle temperature detected by the in-vehicle temperature sensor is falsely high, so that the falsely high in-vehicle temperature needs to be reduced, so that the air conditioner is controlled to operate at a more realistic temperature.

For example, if the first in-vehicle temperature is 25 ℃ and the off time of the air conditioner is 60 seconds, the temperature compensation amount can be determined to be 5 ℃ in step S103, and the compensated in-vehicle temperature is 20 ℃ (i.e., the first in-vehicle temperature is 25 ℃ -5 ℃).

When the first in-vehicle temperature is the in-vehicle temperature obtained at other time except the last closing time of the air conditioner, the first in-vehicle temperature needs to be compensated based on the temperature change between the last closing time of the air conditioner and the other time, and after compensation, the compensated first in-vehicle temperature is compensated again through the temperature compensation quantity.

For example, if the first in-vehicle temperature is 25 ℃, the off time of the air conditioner is 60 seconds, the time from the last off time of the air conditioner to the other time is 30 seconds, the initial compensation amount corresponding to the time of 30 seconds is 2 ℃, and the temperature compensation amount corresponding to the off time is 5 ℃, the first in-vehicle temperature is compensated based on the temperature change between the last off time of the air conditioner and the other time, that is, the first in-vehicle temperature is 25 ℃ to 23 ℃, then the temperature 23 ℃ is the compensated first in-vehicle temperature, and the difference between the compensated first in-vehicle temperature and the temperature compensation amount is calculated again to obtain the compensated in-vehicle temperature, that is, the compensated in-vehicle temperature is 18 ℃ between the first in-vehicle temperature 23 ℃ and the temperature compensation amount 5 ℃.

And when the ambient temperature is higher than the first in-vehicle temperature, controlling the air conditioner to work according to the first in-vehicle temperature.

It should be noted that, considering that, after the air conditioner is controlled to operate according to the compensated in-vehicle temperature, as the control time duration increases, the in-vehicle temperature sensor is gradually weakened by the thermal radiation influence of the peripheral component (the air suction fan or the air suction pipe), at this time, the air conditioner may be controlled to operate according to the in-vehicle temperature actually detected by the in-vehicle temperature sensor.

And the temperature control duration comprises the control duration for controlling the air conditioner to work according to the compensated temperature in the vehicle.

This temperature control period may be obtained by either of the following two implementations:

the first method is as follows: and acquiring the preset temperature control time length.

In this mode, the temperature control period may be set in advance based on an empirical value.

The second method comprises the following steps: the air conditioner terminal voltage of the air conditioner can be obtained, a target voltage range where the air blower terminal voltage is located is determined from a plurality of preset voltage ranges, the temperature control duration corresponding to the target voltage range is determined according to a second preset corresponding relation, and the second preset corresponding relation comprises the temperature control duration corresponding to each voltage range.

In the method, different blower end voltage ranges correspond to different temperature control durations, for example, when the blower end voltage range is 1-3V, the corresponding temperature control duration is 185 seconds, when the blower end voltage range is 13-15V, the corresponding temperature control duration is 62 seconds, and when the blower end voltage range is 22-24V, the corresponding temperature control duration is 15 seconds, so that after the blower end voltage of the air conditioner is obtained, the temperature control duration can be determined according to the blower end voltage.

It should be noted that, the embodiment may also control the operation of the air conditioner according to the off time of the air conditioner, in one possible implementation, the off time of the air conditioner may be detected, whether the off time is less than a preset time or not may be determined, and if the off time is less than the preset time, after the air conditioner is turned off, since the fan is abruptly stopped, the heat radiation of the peripheral member is rapidly concentrated on the periphery of the in-vehicle temperature sensor and is not evacuated, the detection result is greatly influenced, and can be greatly increased (for example, 5 ℃) in a short time (for example, 30 seconds), so that the difference between the temperature in the vehicle detected by the temperature sensor in the vehicle and the real environment temperature of the environment where the vehicle is positioned is larger, the air conditioner is controlled to work according to the compensated temperature in the vehicle, therefore, the temperature difference is compensated, the air conditioner can accurately control the temperature, and the comfort level of a user is improved. If the closing time of the air conditioner is longer than or equal to the preset time, the closing time of the air conditioner is longer, and the heat radiation gathered by the peripheral parts is evacuated for a period of time, so that the influence of the heat radiation of the peripheral parts on the temperature sensor in the vehicle is small, the difference between the temperature in the vehicle detected by the temperature sensor in the vehicle and the ambient temperature of the environment where the vehicle is located is small, temperature compensation is not needed, and therefore the air conditioner can be controlled to work according to the first temperature in the vehicle.

Therefore, according to the closing time of the air conditioner, the air conditioner can be flexibly controlled to work according to different temperatures, and the intelligence of the vehicle for controlling the air conditioner is increased.

By adopting the method, when the environment of the vehicle is a low-temperature environment, the first in-vehicle temperature when the vehicle air conditioner is closed and the environment temperature when the air conditioner is restarted are obtained, the temperature compensation quantity is obtained according to the first in-vehicle temperature and the environment temperature, and the work of the vehicle air conditioner is controlled according to the first in-vehicle temperature and the temperature compensation quantity, so that the condition that the air conditioner controls the work of the air conditioner according to the wrong in-vehicle temperature when the vehicle is in the low-temperature environment is avoided, and the comfort level of a user is improved.

Fig. 2 illustrates a method for controlling a temperature of a vehicle according to an exemplary embodiment of the present disclosure, as shown in fig. 2, including the steps of:

s201, when an air conditioner of the vehicle is turned off, acquiring a first in-vehicle temperature of the vehicle.

The first in-vehicle temperature can be acquired through a temperature sensor arranged in the vehicle. In this embodiment, the first in-vehicle temperature may be an in-vehicle temperature detected at the time when the air conditioner is turned off.

S202, when the air conditioner is turned on again, the ambient temperature of the environment where the vehicle is located is obtained.

In this step, the ambient temperature of the vehicle environment may be detected by a temperature sensor disposed in the engine compartment of the vehicle.

S203, when the environment temperature is smaller than or equal to a preset temperature threshold value, determining whether the environment temperature is smaller than or equal to the first in-vehicle temperature.

When the ambient temperature is less than or equal to the first in-vehicle temperature, executing steps S204 to S209;

when the ambient temperature is greater than the first in-vehicle temperature, step S210 is performed.

And S204, acquiring a temperature compensation amount.

In this step, the temperature compensation amount may be acquired by either of the following two ways:

the first method is as follows: the preset temperature compensation amount is obtained.

In this embodiment, the temperature compensation amount may be set in advance based on an empirical value.

The second method comprises the following steps: determining the closing time length of the air conditioner, determining a target time length range in which the closing time length is located from a plurality of preset time length ranges, and determining the temperature compensation amount corresponding to the target time length range according to a first preset corresponding relation, wherein the first preset corresponding relation comprises the temperature compensation amount corresponding to each time length range. By adopting the mode, the temperature compensation quantity can be flexibly determined according to the closing time of the air conditioner, and the universality of obtaining the temperature compensation quantity is improved.

For example, the temperature compensation amount corresponding to the closing time period 0-200 seconds may be 5 ℃, the temperature compensation amount corresponding to the closing time period 201-400 seconds may be 8 ℃, and the temperature compensation amount corresponding to the closing time period 401-600 seconds may be 6 ℃, which is only illustrated here and is not limited by the present disclosure.

S205, calculating the difference value between the first in-vehicle temperature and the temperature compensation amount to obtain the compensated in-vehicle temperature.

In this step, after the temperature compensation amount is obtained, since the in-vehicle temperature sensor may be affected by heat radiation of the peripheral component at this time, the in-vehicle temperature detected by the in-vehicle temperature sensor is falsely high, so that the falsely high in-vehicle temperature needs to be reduced, so that the air conditioner is controlled to operate at a more realistic temperature.

For example, if the first in-vehicle temperature is 25 ℃ and the off time of the air conditioner is 60 seconds, the temperature compensation amount is determined to be 5 ℃ in step S204, and the compensated in-vehicle temperature is 20 ℃ (i.e., the first in-vehicle temperature is 25 ℃ -5 ℃).

And S206, controlling the air conditioner to work according to the compensated temperature in the vehicle.

And S207, acquiring the temperature control duration.

In this step, the temperature control duration may be obtained in any one of the following two implementation manners:

the first method is as follows: and acquiring the preset temperature control time length.

In this mode, the temperature control period may be set in advance based on an empirical value.

The second method comprises the following steps: the air conditioner terminal voltage of the air conditioner can be obtained, a target voltage range where the air blower terminal voltage is located is determined from a plurality of preset voltage ranges, the temperature control duration corresponding to the target voltage range is determined according to a second preset corresponding relation, and the second preset corresponding relation comprises the temperature control duration corresponding to each voltage range.

In the method, different blower end voltage ranges correspond to different temperature control durations, for example, when the blower end voltage range is 1-3V, the corresponding temperature control duration is 185 seconds, when the blower end voltage range is 13-15V, the corresponding temperature control duration is 62 seconds, and when the blower end voltage range is 22-24V, the corresponding temperature control duration is 15 seconds, so that after the blower end voltage of the air conditioner is obtained, the temperature control duration can be determined according to the blower end voltage.

And S208, acquiring a second in-vehicle temperature of the vehicle after the temperature control time is up.

The second in-vehicle temperature is the in-vehicle temperature after the temperature control time is reached, and the first in-vehicle temperature can be obtained through a temperature sensor arranged in the vehicle.

And S209, controlling the air conditioner to work according to the second in-vehicle temperature.

And S210, controlling the air conditioner to work according to the first in-vehicle temperature.

It should be noted that, the embodiment may also control the operation of the air conditioner according to the off time of the air conditioner, in one possible implementation, the off time of the air conditioner may be detected, whether the off time is less than a preset time or not may be determined, and if the off time is less than the preset time, after the air conditioner is turned off, since the fan is abruptly stopped, the heat radiation of the peripheral member is rapidly concentrated on the periphery of the in-vehicle temperature sensor and is not evacuated, the detection result is greatly influenced, and can be greatly increased (for example, 5 ℃) in a short time (for example, 30 seconds), so that the difference between the temperature in the vehicle detected by the temperature sensor in the vehicle and the real environment temperature of the environment where the vehicle is positioned is larger, the air conditioner is controlled to work according to the compensated temperature in the vehicle, therefore, the temperature difference is compensated, the air conditioner can accurately control the temperature, and the comfort level of a user is improved. If the closing time of the air conditioner is longer than or equal to the preset time, the closing time of the air conditioner is longer, and the heat radiation gathered by the peripheral parts is evacuated for a period of time, so that the influence of the heat radiation of the peripheral parts on the temperature sensor in the vehicle is small, the difference between the temperature in the vehicle detected by the temperature sensor in the vehicle and the ambient temperature of the environment where the vehicle is located is small, temperature compensation is not needed, and therefore the air conditioner can be controlled to work according to the first temperature in the vehicle.

Therefore, according to the closing time of the air conditioner, the air conditioner can be flexibly controlled to work according to different temperatures, and the intelligence of the vehicle for controlling the air conditioner is increased.

By adopting the method, when the environment of the vehicle is a low-temperature environment, the first in-vehicle temperature when the vehicle air conditioner is closed and the environment temperature when the air conditioner is restarted are obtained, the temperature compensation quantity is obtained according to the first in-vehicle temperature and the environment temperature, and the work of the vehicle air conditioner is controlled according to the first in-vehicle temperature and the temperature compensation quantity, so that the condition that the air conditioner controls the work of the air conditioner according to the wrong in-vehicle temperature when the vehicle is in the low-temperature environment is avoided, and the comfort level of a user is improved.
