Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] A car air conditioner is an air conditioning system installed in a vehicle. Its main functions are to regulate the temperature, humidity, air circulation, and air cleanliness inside the vehicle, providing a comfortable environment for passengers. Car air conditioners typically offer both cooling and heating functions to ensure that the interior temperature does not fluctuate drastically with changes in the ambient temperature. When adjusting the interior temperature, the car air conditioner must consider not only the real-time changes in the internal and external environments but also the vehicle's thermal insulation performance.

[0028] refer to Figure 1 , Figure 1 This is a flowchart of a vehicle air conditioning control method according to an embodiment of this application, such as... Figure 1 As shown, the method specifically includes the following steps: S11: When the vehicle is powered on, the interior temperature is collected by the first temperature sensor.

[0029] In this embodiment, the first temperature sensor is installed inside the vehicle to collect the interior temperature and convert it into an electrical signal for the air conditioning system to reference.

[0030] In this embodiment, when the vehicle is powered on, the vehicle air conditioning system controls the first temperature sensor to collect the interior temperature.

[0031] For example, the first temperature sensor may be a thermistor sensor whose resistance changes with temperature, and the temperature inside the vehicle is determined based on the change in resistance.

[0032] S12: If the absolute value of the temperature difference between the vehicle interior temperature and the target temperature exceeds a first preset value, the corresponding temperature control switch is turned on.

[0033] In this embodiment, the target temperature is a preset ideal temperature value inside the vehicle. The temperature control switch includes a cooling switch and a heating switch. When the cooling switch is turned on, the air conditioner cools the interior of the vehicle; when the heating switch is turned on, the air conditioner heats the interior of the vehicle.

[0034] In this embodiment, after the vehicle interior temperature is collected, it is compared with a preset target temperature. If the absolute value of the difference between the vehicle interior temperature and the target temperature exceeds a first preset value, it is determined whether the difference is positive or negative. If the difference is positive, the cooling switch is turned on; if the difference is negative, the heating switch is turned on.

[0035] For example, the first preset value is 1.

[0036] S13: When the temperature control switch is activated, the ambient temperature is collected by the second temperature sensor.

[0037] In this embodiment, the second temperature sensor is installed on the exterior of the vehicle body to collect the temperature of the current environment in which the vehicle is located.

[0038] In this embodiment, when the temperature control switch is activated, the vehicle air conditioning system activates the second temperature sensor to collect the ambient temperature of the vehicle.

[0039] S14: Adjust the vehicle temperature according to the in-vehicle temperature, the ambient temperature, and the target temperature using a corresponding temperature adjustment rate.

[0040] In this embodiment, the temperature adjustment rate refers to the number of degrees the vehicle air conditioner adjusts the temperature per second. In cooling mode, it is the number of degrees the temperature drops per second, and in heating mode, it is the number of degrees the temperature rises per second.

[0041] In this embodiment, after collecting the ambient temperature, the vehicle temperature is adjusted based on the interior temperature and the ambient temperature, combined with a corresponding temperature adjustment rate. During the temperature adjustment process, the thermal insulation coefficient needs to be considered. The thermal insulation coefficient depends on the vehicle's materials and is generally provided by the manufacturer. The greater the difference between the interior temperature and the actual temperature, the faster the temperature adjustment rate, ensuring that the vehicle quickly reaches the target temperature.

[0042] For example, if the difference between the vehicle interior temperature and the ambient temperature is small, the vehicle temperature is adjusted at a small rate, and the temperature adjustment is stopped after the target temperature is reached.

[0043] In this embodiment, the vehicle air conditioning system automatically adjusts the vehicle interior temperature based on the current actual temperature inside the vehicle and the ambient temperature. It can also adaptively change the temperature adjustment rate so that the vehicle can quickly reach the target temperature, ensuring the comfort of the passengers.

[0044] In another embodiment of this application, the method further includes: S21: Query the historical temperature control parameters corresponding to the vehicle interior temperature, the ambient temperature, and the target temperature in the vehicle's historical temperature control records.

[0045] In this embodiment, the vehicle's historical temperature control record stores the vehicle's historical temperature control parameters, including the vehicle's past interior temperature, ambient temperature, target temperature, temperature adjustment rate, and adjustment time at the interior temperature and target temperature.

[0046] In this embodiment, each time the vehicle performs temperature adjustment, it records the parameters for that temperature adjustment, including the current in-vehicle temperature, ambient temperature, target temperature, temperature adjustment frequency, and duration. When the vehicle adjusts the temperature subsequently, the current vehicle temperature, ambient temperature, and target temperature are first compared with the historical temperature adjustment parameters in the vehicle's historical temperature adjustment records to determine the closest record.

[0047] For example, there are multiple historical temperature control records of vehicles that are similar to the current vehicle temperature, ambient temperature, and target temperature. By comparing the target temperatures in these multiple historical temperature control records, the record with the longest target temperature activation time is selected as the corresponding historical temperature control parameter.

[0048] S22: Adjust the temperature of the vehicle according to the historical temperature control parameters.

[0049] In this embodiment, after determining the historical temperature control parameters corresponding to the current vehicle interior temperature, ambient temperature, and target temperature, the vehicle temperature is directly adjusted using these historical temperature control parameters. The temperature adjustment rate corresponding to these historical temperature control parameters is then used to adjust the vehicle interior temperature to the target temperature.

[0050] In this embodiment, the air conditioning system can directly apply the parameters in the historical temperature control records, without having to perform calculations every time it is powered on, thus saving time on temperature control.

[0051] In another embodiment of this application, the step of activating a corresponding temperature control switch when the absolute value of the temperature difference between the vehicle interior temperature and the target temperature exceeds a first preset value includes: S31: When the absolute value of the temperature difference between the vehicle interior temperature and the target temperature exceeds the first preset value and the difference is positive, the first temperature control switch is turned on.

[0052] In this embodiment, the first temperature control switch is a cooling switch. After the cooling switch is turned on, the interior of the vehicle is cooled down.

[0053] In this embodiment, if the absolute value of the difference between the vehicle interior temperature and the target temperature exceeds the first preset value and the difference is positive, it indicates that the vehicle interior temperature is high. At this time, the first temperature control switch is turned on to cool the vehicle.

[0054] For example, when the compressor is enabled for cooling, AC_Ena=1. Cooling starts when Act_TEMP-Set_TEMP>=1, and stops when Act_TEMP-Set_TEMP<1. Cooling starts again when the temperature rises to Act_TEMP-Set_TEMP>3.

[0055] Here, AC_Ena enables the air conditioning compressor, Act_TEMP is the interior temperature, and Set_TEMP is the target temperature.

[0056] S32: If the absolute value of the temperature difference between the vehicle interior temperature and the target temperature exceeds the first preset value and the difference is negative, turn on the second temperature control switch.

[0057] In this embodiment, the second temperature control switch is a heating switch. After the heating switch is turned on, the interior of the vehicle is heated.

[0058] In this embodiment, if the absolute value of the difference between the vehicle interior temperature and the target temperature exceeds the first preset value and the difference is negative, it indicates that the vehicle interior temperature is low. At this time, the second temperature control switch is turned on to heat the vehicle.

[0059] For example, when the heat pump is enabled by the hot start motor, the air conditioner heating switch is turned on, and the cooling water pump starts (PTC_Ena=1). When Act_TEMP-Set_TEMP>=-1, heating starts; when Act_TEMP-Set_TEMP<-1, heating stops. When the temperature rises again to Act_TEMP-Set_TEMP<-3, heating starts again.

[0060] PTC_Ena enables the heat pump.

[0061] In this embodiment, the system automatically determines whether to heat or cool based on the difference between the interior temperature and the actual temperature, ensuring rapid and accurate adjustment of the interior temperature.

[0062] In another embodiment of this application, adjusting the vehicle temperature using a corresponding temperature adjustment rate based on the in-vehicle temperature, the ambient temperature, and the target temperature includes: S41: Determine the temperature difference between the vehicle interior temperature and the target temperature.

[0063] In this embodiment, when adjusting the vehicle interior temperature, the vehicle interior temperature and the target temperature are obtained, and the temperature difference is determined based on the vehicle interior temperature and the target temperature.

[0064] S42: Adjust the temperature of the vehicle according to the temperature difference using the corresponding temperature adjustment rate.

[0065] In this embodiment, after determining the temperature difference, the corresponding temperature adjustment rate is selected according to the magnitude of the temperature difference to adjust the vehicle temperature. When the temperature difference is large, a larger temperature adjustment rate is used, and when the temperature difference is small, a smaller temperature adjustment rate is used.

[0066] In this embodiment, different temperature adjustment rates are selected to adjust the vehicle temperature according to different temperature differences, so as to save vehicle energy while ensuring that the vehicle temperature is quickly adjusted to the target temperature.

[0067] In another embodiment of this application, adjusting the vehicle temperature according to the temperature difference using the corresponding temperature adjustment rate includes: S51: When the absolute value of the temperature difference exceeds a first preset value but does not exceed a second preset value, the vehicle temperature is adjusted at a first temperature adjustment rate.

[0068] In this embodiment, the first preset value is less than the second preset value. When the absolute value of the temperature difference exceeds the first preset value but does not exceed the second preset value, it indicates that the temperature difference between the vehicle interior and the target temperature is small. At this time, a smaller temperature adjustment rate can be used to save vehicle energy.

[0069] For example, when |Act_TEMP-Set_TEMP|<10 and |Act_TEMP-Set_TEMP|≥1, Drop_TEMP=-(Act_TEMP-Set_TEMP / 60), where Act_TEMP is the interior temperature, Set_TEMP is the target temperature, and Drop_TEMP is the temperature adjustment rate.

[0070] The formula determines the temperature difference between the actual temperature inside the car and the target temperature if the absolute value is greater than or equal to 1°C and less than 10°C. The formula also determines the temperature adjustment frequency of the air conditioner (cooling or heating) per second. The formula calculates the difference between the actual temperature inside the car and the target temperature divided by 60 seconds. A positive result indicates a high temperature requiring cooling, so a negative sign is added before the formula. A negative result indicates a low temperature requiring heating, so a symbol is added before the formula.

[0071] S52: If the absolute value of the temperature difference exceeds a second preset value but does not exceed a third preset value, the vehicle temperature is adjusted at a second temperature adjustment rate.

[0072] In this embodiment, the second preset value is less than the third preset value.

[0073] In this embodiment, if the absolute value of the temperature difference exceeds the second preset value but does not exceed the third preset value, it indicates that the temperature difference between the vehicle interior and the target temperature is large. In this case, the vehicle temperature is adjusted at the second temperature adjustment rate.

[0074] For example, |Act_TEMP-Set_TEMP|≥10 and |Act_TEMP-Set_TEMP|<20, Drop_TEMP=-(Act_TEMP-Set_TEMP / 80).

[0075] The formula is used to determine the temperature difference between the actual temperature inside the car and the target temperature. The absolute value of the difference is greater than or equal to 10°C and less than 20°C. The formula is the temperature adjustment frequency of the air conditioner when it is turned on for cooling or heating, and the difference between the actual temperature inside the car and the target temperature is divided by 80 seconds.

[0076] S53: If the absolute value of the temperature difference exceeds a third preset value but does not exceed a fourth preset value, the vehicle temperature is adjusted at a third temperature adjustment rate.

[0077] In this embodiment, the third preset value is less than the fourth preset value. The fourth preset value is the upper limit of the temperature difference. When the temperature difference exceeds this limit, the difference between the interior temperature and the target temperature is too large, and the air conditioning system cannot adjust the temperature.

[0078] In this embodiment, if the absolute value of the temperature difference exceeds the third preset value but does not exceed the fourth preset value, it indicates that the temperature difference between the vehicle interior temperature and the target temperature is large. At this time, the vehicle temperature is adjusted at the third temperature adjustment rate to ensure that the vehicle can quickly reach the target temperature.

[0079] For example, |Act_TEMP-Set_TEMP|≥30, Drop_TEMP=-(Act_TEMP-Set_TEMP / 150). The fourth temperature difference is 40 degrees.

[0080] The formula is to determine the temperature adjustment frequency of the air conditioner (cooling or heating) by dividing the difference between the actual temperature inside the car and the target temperature by 150 seconds, based on the absolute value of the difference between the actual temperature inside the car and the target temperature being greater than or equal to 30°C.

[0081] Based on the above formula, the temperature adjustment frequency for braking, air conditioning cooling, or heating can be adjusted. The frequency can be adjusted between -3 and 3℃ / s, depending on the vehicle's own heating or cooling power.

[0082] In this embodiment, the corresponding temperature adjustment rate is selected based on the difference between the vehicle interior temperature and the target temperature, so as to save vehicle energy while ensuring that the vehicle interior temperature quickly reaches the target temperature.

[0083] In another embodiment of this application, the method further includes: S61: Determine the actual temperature of the vehicle based on the interior temperature, the ambient temperature, the vehicle's thermal insulation coefficient, and the temperature adjustment rate.

[0084] In this embodiment, the in-vehicle temperature after heat conduction is determined based on the in-vehicle temperature, ambient temperature, and the vehicle's thermal insulation coefficient. Then, the actual temperature of the vehicle after temperature adjustment per second is determined by combining the temperature adjustment rate.

[0085] S62: If the actual temperature is the same as the target temperature, stop the vehicle temperature adjustment.

[0086] In this embodiment, the vehicle temperature adjustment is stopped when the actual temperature of the vehicle after temperature adjustment is the same as the target temperature.

[0087] In this embodiment, determining the actual temperature of the vehicle based on the in-vehicle temperature, the ambient temperature, the vehicle's thermal insulation coefficient, and the temperature adjustment rate includes: S71: Determine the interior temperature of the vehicle after heat conduction based on the interior temperature, the ambient temperature, and the thermal insulation coefficient.

[0088] In this embodiment, when adjusting the temperature of the vehicle, the heat conduction inside and outside the vehicle needs to be taken into account. That is, the temperature will be lost during the adjustment process, and the temperature will not be reduced or increased completely according to the temperature adjustment rate.

[0089] For example, considering the influence of the car's own thermal insulation, the temperature inside the car can be controlled by multiplying the difference between the ambient temperature and the interior temperature by the thermal insulation coefficient. That is (Env_TEMP-Act_TEMP) * Thermal Isolation Among them, Env_TEMP is the ambient temperature, Act_TEMP is the interior temperature of the vehicle, and Thermal Isolation is the thermal insulation coefficient, which is generally provided by the car manufacturer.

[0090] S72: Determine the actual temperature by using the temperature tuning frequency and the interior temperature after heat conduction.

[0091] In this embodiment, after obtaining the interior temperature of the vehicle after heat conduction, the actual interior temperature is determined by combining the temperature adjustment rate.

[0092] For example, the expression is: Drop_TEMP+(Env_TEMP-Act_TEMP)* Thermal Isolation+ Act_TEMP In the above formula, Drop_TEMP represents the temperature drop per second, and Drop_TEMP is the cooling frequency per second, indicating the degree Celsius decrease per second. (Env_TEMP - Act_TEMP) * Thermal Isolation calculates a value considering the thermal insulation effect of the car's materials. The thermal isolation coefficient is determined by the car's materials and is generally provided by the car manufacturer. Act_TEMP represents the actual interior temperature of the car. This formula calculates the actual interior temperature of the car after the temperature drops per second; over time, the interior temperature will eventually reach the user's desired temperature.

[0093] In this embodiment, the vehicle's thermal insulation properties are taken into account during the cooling process, and the vehicle's temperature is accurately calculated to ensure the accuracy of the vehicle temperature adjustment.

[0094] In the above embodiments of this application, the vehicle's air conditioning system automatically adjusts the interior temperature by combining the interior temperature and ambient temperature. Furthermore, it adjusts the temperature adjustment rate based on the difference between the interior temperature and the target temperature, quickly reaching the target temperature while saving energy. By recording the user's historical temperature adjustment parameters and setting corresponding target temperatures, air conditioning temperature adjustment rates, and other parameters, computational resources are saved. This achieves the goal of quickly and accurately adjusting the interior temperature.
