Then, according to the difference between the ambient temperature in the car and the target temperature, the operating frequency of the compressor is adjusted to achieve precise control of the temperature in the car. However, after a long journey, the vehicle may cross regions, causing significant changes in the external environment. The parking air conditioner is turned on and running according to the last shutdown state, which is not suitable for the environment in the current area, affecting the user experience.

[0018] If the average value of the ambient temperature is ≥ the second preset temperature, and the average value of the ambient humidity is < the second preset humidity, then the target temperature = the second preset temperature + the second preset temperature difference; and / or

[0019] If the average ambient temperature is less than the second preset temperature, the target temperature is equal to the average ambient temperature.

[0020] In the preferred technical solution of the above control method, “determining the target temperature according to the operation mode of the air conditioner, the average value of the ambient temperature and the average value of the ambient humidity” specifically includes:

[0021] When the air conditioner operates in a heating mode, if the average value of the ambient temperature is less than the third preset temperature, and the average value of the ambient humidity is greater than the first preset humidity, then the target temperature = the third preset temperature + the third preset temperature difference; and / or

[0022] If the average ambient temperature ≥ the third preset temperature, the target temperature = the average ambient temperature.

[0023] In the preferred technical solution of the above control method, the control method of the parking air conditioner further includes the following steps:

[0024] Get the illumination coefficient;

[0025] A compressor target operating frequency is determined according to the operating mode, the illumination factor and the current operating frequency.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] In order to solve the problem that after a vehicle has traveled a long distance, it may cross regions and cause significant changes in the external environment. The parking air conditioner is turned on according to the last shutdown state, which is not suitable for the local environment and affects the user experience.

[0047] like Figure 1 As shown, this embodiment discloses a parking air conditioner control method, the parking air conditioner includes a control system, a refrigerant circulation pipeline, a compressor installed on the refrigerant circulation pipeline, a condenser, a four-way valve, an electronic expansion valve and an evaporator, and the cooling and heating cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the vehicle compartment. The control system includes a control module, at least one light sensing detection element and an in-vehicle ambient temperature detection element, the light sensing detection element is used to detect the current light value and transmit the information to the control module, and the in-vehicle ambient temperature detection element is used to detect the in-vehicle ambient temperature and transmit the information to the control module. In this embodiment, the light sensing detection element is a light sensor, and the in-vehicle ambient temperature detection element is an in-vehicle ambient temperature sensor.

[0048] The control module includes an information collection unit, a control unit and a storage unit. The information collection unit is connected to the light sensor and the in-vehicle ambient temperature sensor in communication, and can receive the current light value and the in-vehicle ambient temperature in real time. The information collection unit can also obtain environmental information of the location within a set time from the network, such as the ambient temperature value and ambient humidity value of the location within the past 7 days, 10 days or 15 days, so that the control system has comprehensive environmental perception capabilities. The information collection unit is connected to the control unit in communication, and can also transmit the received current light value, the in-vehicle ambient temperature, and the ambient temperature and humidity value of the location of the air conditioner within the set time to the control unit. The storage unit stores program execution instructions, and the control unit is configured to execute the control method of the parking air conditioner when running the program instructions.

[0049] like Figure 1 As shown, the control method of the parking air conditioner mainly includes the following steps:

[0050] S1. Determine an operating mode of the air conditioner according to the ambient temperature in the vehicle and a first preset temperature.

[0051] S2. Determine a target temperature according to the operating mode and environmental information of the location of the air conditioner within a set time.

[0052] S3. Determine the current operating frequency of the compressor according to the vehicle interior ambient temperature and the target temperature.

[0053] After the parking air conditioner is started, the air conditioner is first determined to operate in cooling mode or heating mode according to the relationship between the ambient temperature in the vehicle and the first preset temperature. Then, the target temperature is determined according to the operating mode of the air conditioner and the environmental information of the location of the air conditioner within the set time; and then, according to the difference between the ambient temperature in the vehicle and the target temperature, the current operating frequency at which the compressor should operate is calculated, so that the parking air conditioner can output a more suitable cooling capacity or heating capacity, so that the ambient temperature in the vehicle can reach and maintain the target temperature faster, thereby improving the comfort of the human body.

[0054] Compared with using the target temperature when the air conditioner was last shut down or the pre-set target temperature as the target temperature for this air conditioning operation, determining the target temperature for this air conditioning operation is based on the air conditioning operation mode and the environmental information of the air conditioner's location within the set time. This can make the target temperature more in line with the user's physical needs in the current environment, improve the user experience, and enable the parking air conditioner to adapt to the current environment.

[0055] like Figure 2 As shown, the control method of the parking air conditioner specifically includes the following steps:

[0056] S1. Obtain the interior ambient temperature of the vehicle in real time through the interior ambient temperature sensor and transmit it to the control module.

[0057] S2, the control module obtains the ambient temperature value and the ambient humidity value of the air conditioner location within the set time in real time, and calculates the average ambient temperature and the average ambient humidity. The set time can be 7 days, 10 days or 15 days. Preferably, the set time is 15 days. By obtaining more parameter values, the calculated average ambient temperature and average ambient humidity can better represent the environmental information of the current location.

[0058] S3. The current light value is obtained in real time through the light sensor. The light value affects the temperature exchange between the inside and outside of the vehicle and is an important parameter affecting the ambient temperature inside the vehicle. For example, the compressor operating frequency is controlled to increase the cooling power under strong sunlight, or the cooling load is appropriately reduced when the light is weakened or at night. By increasing the parameter value of the current light value, the operating frequency of the compressor is controlled and adjusted, so that the parking air conditioner can better adapt to the current environment, providing users with a comfortable temperature while improving energy utilization.

[0059] S40. Determine whether the ambient temperature inside the vehicle is ≤ the first preset temperature - a°C. The first preset temperature is an adjustable value preset manually. a is a constant. a can be 0, 0.5, 1, 2, 3, etc. The smaller a is, the easier it is for the air conditioner to start the heating mode to increase the temperature inside the vehicle for the user. The larger a is, the number of times the air conditioner starts the heating mode can be reduced, thereby reducing energy consumption. Preferably, the first preset temperature is 25°C and a is 1, so that the air conditioner can better provide a comfortable environment for the user.

[0060] If the vehicle interior ambient temperature is ≤ the first preset temperature - a°C, S5 is executed and the air conditioner operates in a heating mode; if the vehicle interior ambient temperature is > the first preset temperature - a°C, S41 is executed.

[0061] S41, determine whether the vehicle interior ambient temperature is greater than the first preset temperature + a℃, where a is a constant and has the same value as above. At this time, the smaller a is, the easier it is for the air conditioner to start the cooling mode and lower the temperature in the vehicle compartment for the user. If the vehicle interior ambient temperature is greater than the first preset temperature + a℃, then execute S6, and the air conditioner runs in the cooling mode; if the judgment condition is not met, that is, the first preset temperature - a℃ < vehicle interior ambient temperature ≤ the first preset temperature + a℃, then execute S7, and the air conditioner is turned off. At this time, the vehicle interior ambient temperature is relatively comfortable and there is no need to adjust the temperature. Controlling the air conditioner to turn off can reduce energy consumption.

[0062] S50, judging whether the average value of the ambient temperature is less than the third preset temperature, the third preset temperature is an adjustable value preset manually, in this embodiment, the third preset temperature is 22°C. If the average value of the ambient temperature is less than the third preset temperature, executing S501; if the average value of the ambient temperature is greater than or equal to the third preset temperature, executing S502, controlling the output target temperature to be equal to the average value of the ambient temperature, the target temperature is a temperature that is more comfortable for the user in the current environment, and is also the temperature in the vehicle that the air conditioning control system hopes to achieve and maintain.

[0063] S501, determine whether the average value of the ambient humidity is greater than the third preset humidity, the third preset humidity is a preset value, preferably, the third preset humidity is 65%, if the average value of the ambient humidity is greater than 65%, then execute S5011, control the output target temperature = the third preset temperature + the third preset temperature difference, preferably, the third preset temperature difference is 1° C. If the average value of the ambient humidity is ≤ 65%, then execute S5012, control the output target temperature = the third preset temperature.

[0064] S51. According to the difference between the ambient temperature in the vehicle and the target temperature, the control module calculates the current operating frequency fi of the compressor, and controls the compressor to operate at the operating frequency, so that the parking air conditioner can output a more suitable heating amount, so that the ambient temperature in the vehicle can reach and maintain the target temperature more quickly, improving the comfort of the human body. And when the vehicle travels to different positions, different average ambient temperature and average ambient humidity are obtained. According to the judgment conditions of steps S50 and S501, the output target temperature can be dynamically adjusted, thereby adjusting the current operating frequency of the compressor, so that the air conditioner can adapt to the current environment and provide a more suitable temperature in the vehicle.

[0065] S52, calculate the illumination coefficient L = current illumination value / optimal illumination value, the optimal illumination value is predetermined according to the suitable temperature of the human body, the illumination coefficient is calculated in real time by the ratio of the current illumination value detected in real time by the illumination sensor to the optimal illumination value, and is used as a parameter value to adjust the target operating frequency of the compressor.

[0066] S53. Calculate the compressor target operating frequency F = fi*Kj*(1 / L), and adjust the compressor operating frequency to the compressor target operating frequency. Wherein, fi is the current operating frequency of the compressor, L is the light coefficient, Kj is the second adjustment coefficient, 0<Kj≤1, and the second adjustment coefficient can be obtained through a large number of laboratory tests and field tests during the product development stage. The second adjustment coefficient represents the degree of influence of changes in light values ​​on the heating efficiency of the air conditioner. When the air conditioner is in heating mode, the compressor target operating frequency is inversely proportional to the light coefficient, that is, the stronger the light, the compressor target operating frequency may be appropriately reduced to reduce the heating amount, because strong light will cause a certain temperature rise trend in the car, so it is necessary to reduce the heating intensity.

[0067] S60, judging whether the average value of the ambient temperature is ≥ the second preset temperature, if the average value of the ambient temperature is ≥ the second preset temperature, executing S601, if the average value of the ambient temperature is < the second preset temperature, executing S602, controlling the output target temperature to be equal to the average value of the ambient temperature.

[0068] S601, determine whether the average value of the ambient humidity is greater than the first preset humidity, the first preset humidity is a preset value, preferably, the first preset humidity is 65%. If the average value of the ambient humidity is greater than 65%, execute S6011, control the output target temperature = the second preset temperature - the first preset temperature difference, the first preset temperature difference is a preset value, preferably, the first preset temperature difference is 1°C; if the average value of the ambient humidity is ≤65%, execute S6012.

[0069] S6012: Determine whether the average value of the ambient humidity is less than the second preset humidity, the second preset humidity is a preset value, preferably, the second preset humidity is 45%. If the average value of the ambient humidity is less than 45%, execute S60121, control the output target temperature = the second preset temperature + the second preset temperature difference, the second preset temperature difference is a preset value, preferably, the second preset temperature difference is 1°C, if 45% ≥ the average value of the ambient humidity is less than 65%, execute S60122, control the output target temperature = the second preset temperature.

[0070] S61. According to the difference between the ambient temperature in the vehicle and the target temperature, the control module calculates the current operating frequency fi of the compressor, and controls the compressor to operate at the operating frequency, so that the parking air conditioner can output a more suitable cooling capacity, so that the ambient temperature in the vehicle can reach and maintain the target temperature more quickly, improving the comfort of the human body. And when the vehicle travels to different positions, different average ambient temperature and average ambient humidity are obtained. According to the judgment conditions of steps S60, S601 and S6012, the output target temperature can be dynamically adjusted, thereby adjusting the current operating frequency of the compressor, so that the air conditioner can adapt to the current environment and provide a more suitable temperature in the vehicle.

[0071] S62, calculate the illumination coefficient = current illumination value / optimal illumination value, where the optimal illumination value is predetermined based on the suitable temperature for the human body.

[0072] S63. Calculate the compressor target operating frequency F=fi*Ki*L, and adjust the compressor operating frequency to the compressor target operating frequency. Wherein, fi is the current operating frequency of the compressor, L is the light coefficient, Ki is the first adjustment coefficient, 0<Ki≤1, and the first adjustment coefficient can be obtained through a large number of laboratory tests and field tests during the product development stage to ensure that the air conditioner operates within a reasonable and efficient range. The first adjustment coefficient represents the degree of influence of changes in light values ​​on the air conditioning refrigeration efficiency. When the air conditioner is in cooling mode, the compressor target operating frequency is proportional to the light coefficient, that is, the stronger the light, the compressor target operating frequency may be increased accordingly to increase the cooling capacity, because strong light will cause a certain temperature rise trend in the car, which requires an increase in cooling power.

[0073] After the parking air conditioner is started, the cooling mode or heating mode of the air conditioner is determined based on the relationship between the ambient temperature in the car and the first preset temperature ±a℃. Then, according to the operating mode of the air conditioner and the average ambient temperature and the average ambient humidity within the set time at the location of the air conditioner obtained in real time, the target temperature of the air conditioner operation is dynamically adjusted so that the target temperature can better meet the user's physical needs in the current environment. Compared with the target temperature when the air conditioner was last shut down as the target temperature of this air conditioner operation, the parking air conditioner in this embodiment can adapt to the current environment and improve the user experience. Then determine the illumination coefficient based on the current illumination value, and determine the compressor target operating frequency based on the illumination coefficient, the current operating frequency of the compressor and the air conditioner operating mode. When the air conditioner is in heating mode, the compressor target operating frequency F=fi*Kj*(1 / L), and when the air conditioner is in cooling mode, the compressor target operating frequency F=fi*Ki*L, and adjust the compressor operating frequency to the target compression frequency, so that the ambient temperature in the car can reach and maintain the target temperature faster, thereby improving the comfort of the human body.

[0074] The vehicle's ambient temperature, light value, average ambient temperature at the air conditioner's location within a set time, and average ambient humidity are used as parameter values ​​to control and adjust the operation of the air conditioner. This allows the parking air conditioner to adapt to the current environment, provide a comfortable and stable temperature inside the vehicle, and effectively improve energy efficiency.

[0075] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
