Description

Technical Field

[0002] With drivers increasingly prioritizing driving comfort, air conditioning systems have become an indispensable comfort feature in commercial vehicles. User surveys reveal that manual air conditioning control is the most common method. Generally, electric vehicles use the same control algorithm for both manual and automatic temperature control. This algorithm performs calculations after each manual temperature setting, resulting in lengthy calculation times and large amounts of data. The actual temperature stabilization process for users takes a long time, sometimes even several minutes, and the large amount of data required necessitates that the air conditioning controller have sufficient memory to support both manual and automatic temperature settings using the same algorithm. However, manual temperature control is essentially a process of adjusting the temperature based on the user's perceived temperature trend; it doesn't need to perfectly match the set temperature. It only needs to ensure that the user's comfortable temperature falls within the adjustable temperature range to meet the requirements. Summary of the Invention

[0019] The first surface outlet temperature of the air conditioner evaporator is obtained by weighted averaging the air outlet temperature of the test surface corresponding to each test.

[0020] In one embodiment, determining the air conditioner's output temperature based on the air conditioner's set temperature and the outlet air temperature reference value corresponding to the target operating device type includes:

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0048] The method for determining the output temperature of a vehicle air conditioner provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 acquires the outdoor ambient temperature of the target vehicle and the air conditioning setting temperature triggered by the driver. Terminal 102 communicates with server 104 via a network, sending the acquired temperature values ​​to server 104. Server 104 analyzes and processes the data to determine the output temperature of the vehicle's air conditioning. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated on server 104 or located on the cloud or other network servers. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle devices. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0049] First, it should be noted that the temperature determination method provided in this application embodiment is applied to the control of a manual air conditioner, and the arrangement of the heat exchanger and sensor structure inside the air conditioner unit is as follows: Figure 2 As shown, the airflow passes through the evaporator, heat pump heat exchanger, and heater respectively. The evaporator surface outlet air temperature sensor is arranged at the evaporator outlet end close to the heat exchanger wall. The heat pump heat exchanger surface outlet air temperature sensor is arranged at the heat pump heat exchanger outlet end close to the heat exchanger wall. The heater surface outlet air temperature sensor is arranged at the heater outlet end close to the heat exchanger wall.

[0050] In one embodiment, such as Figure 3 As shown, a method for determining the output temperature of a vehicle air conditioner is provided, which is then applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0051] Step 302: Obtain the on / off status of the air conditioning cooling switch of the target vehicle and the outdoor temperature value of the target vehicle.

[0052] The vehicle's air conditioning cooling switch, also known as the AC (Air Conditioning) button, controls the on / off state of the air conditioning compressor. When the AC button is pressed, the compressor starts working, blowing out cold air to achieve cooling. The on / off state of the air conditioning cooling switch is the same as the state of the AC button, which can be obtained through the AC signal line connected to the AC button. The outdoor temperature of the target vehicle can be obtained through an external temperature sensor on the target vehicle.

[0053] Step 304: Determine the type of target working device on the target vehicle that provides the corresponding air conditioning function based on the on status and outdoor temperature value;

[0054] The target working device type refers to the classification of devices inside the vehicle's air conditioning system used to achieve different functions. For example, when the temperature is high, the vehicle's air conditioning system provides cold air to achieve a cooling function, while when the temperature is low, the vehicle's air conditioning system can provide warm air to achieve a heating function. Specifically, in one embodiment, the air conditioning system of the target vehicle includes devices such as a compressor, heat pump, fan, evaporator, and electric auxiliary heating.

[0055] The on / off status of the air conditioning switch can determine the driver's needs for the vehicle's air conditioning, such as whether cooling is required or not. The outdoor temperature value allows for a more precise determination of the level of demand, such as weak cooling, strong cooling, weak heating, or strong heating. Specifically, by analyzing the on / off status of the air conditioning switch and the outdoor temperature value, the operating mode of the target vehicle's air conditioning can be determined. In other words, by analyzing the on / off status and outdoor temperature value, the driver's functional needs for the air conditioning can be identified, thus pinpointing the target operating device within the air conditioning system that provides the corresponding function. Furthermore, the output temperature of the vehicle's air conditioning system after the target operating device is activated can be analyzed.

[0056] Step 306: Obtain the air conditioning setting temperature of the target vehicle, and determine the air conditioning output temperature based on the air conditioning setting temperature and the air outlet temperature reference value of the corresponding device of the target working device type.

[0057] The air conditioning set temperature refers to the driver's desired temperature in the target vehicle, which is manually input into the vehicle's air conditioning control system by the driver. The outlet air temperature reference value indicates the upper and lower limits of the temperature that the working device can provide during operation; for each working device, there are at least two outlet air temperature reference values. The air conditioning set temperature essentially represents a driver's desired temperature value. In this embodiment, the air conditioning output temperature after the initial attack device is activated is quickly determined by using the air conditioning set temperature and the outlet air temperature reference value of the device corresponding to the target working device type.

[0058] The method provided in the above embodiments obtains the on / off status of the air conditioning cooling switch of the target vehicle and the outdoor temperature value of the target vehicle; based on the on / off status and the outdoor temperature value, it determines the type of target working device on the target vehicle that provides the corresponding air conditioning function; it obtains the air conditioning set temperature of the target vehicle, and determines the air conditioning output temperature based on the air conditioning set temperature and the air outlet temperature reference value of the corresponding device of the target working device type. Based on the temperature value manually set by the driver, it automatically finds the control mode and accurately calculates the air outlet temperature value corresponding to the air conditioning set temperature. This method is simple and fast, greatly reducing the amount of calculation and quickly meeting the temperature requirements of the vehicle driver.

[0059] In one embodiment, such as Figure 4 As shown, based on the on / off status and outdoor temperature, the type of target working device providing the corresponding air conditioning function on the target vehicle is determined, including:

[0060] Step 402: When the air conditioning is turned on in the on state, if the outdoor temperature is greater than the first preset temperature, the target working device type that provides the corresponding air conditioning function on the target vehicle is determined to be a compressor; if the outdoor temperature is not greater than the first preset temperature, the target working device type that provides the corresponding air conditioning function on the target vehicle is determined to be a compressor and a heat pump.

[0061] Step 404: When the air conditioning is turned off in the on state, if the outdoor temperature is less than the second preset temperature, the target working device type that provides the corresponding air conditioning function on the target vehicle is determined to be an electric auxiliary heating device; if the outdoor temperature is not less than the second preset temperature, the target working device type that provides the corresponding air conditioning function on the target vehicle is determined to be a heat pump; wherein, the first preset temperature is greater than the second preset temperature.

[0062] It should be noted that when the air conditioner's cooling switch is on, the air conditioner is in cooling mode, and when the cooling switch is off, the air conditioner is in heating mode. First, the air conditioner's status is determined by the on / off state of the cooling switch. Then, based on the specific outdoor temperature value, the target operating device providing the corresponding function within the air conditioner is determined. In one embodiment, see... Figure 5After the air conditioning system is turned on, it first checks whether the AC (air conditioning cooling switch) is activated. If the AC is activated, it checks the outdoor temperature. If the outdoor temperature is greater than 10°C, the compressor starts. If the outdoor temperature is less than or equal to 10°C, both the compressor and the heat pump start. If the AC is not activated, it also checks the outdoor temperature. If the outdoor temperature is greater than or equal to -5°C, only the heat pump starts. If the outdoor temperature is less than -5°C, only the PTC heater starts.

[0063] like Figure 5 As shown, after the car is started and the air conditioning system is turned on, the air conditioning will enter four operating modes. Each operating mode corresponds to a different type of operating device, and the process for determining the air conditioning output temperature is also different. In the method provided in the above embodiment, by setting conditions to quickly determine the operating mode of the vehicle's air conditioning and the corresponding target operating device type, it can quickly respond to the driver's temperature needs.

[0064] In one specific embodiment, the output temperature of the air conditioner is determined based on the air conditioner's set temperature and the reference value of the outlet air temperature of the device corresponding to the target operating device type, including:

[0065] When the target working device type is a compressor, the first surface air outlet temperature of the air conditioner evaporator is obtained when the compressor is in the maximum cooling state, and the second surface air outlet temperature of the air conditioner evaporator is obtained when the compressor is in the maximum cooling state at a first preset percentage state.

[0066] Based on the first surface outlet temperature and the second surface outlet temperature, the actual surface outlet temperature of the air conditioner evaporator at the air conditioner setting temperature is calculated and used as the output temperature of the air conditioner.

[0067] The specific calculation formula can be:

[0068]

[0069] Among them, T 设 Set the temperature for the air conditioner; T 蒸 T1 represents the actual surface outlet temperature of the air conditioner evaporator; T2 represents the first surface outlet temperature of the air conditioner evaporator; and T3 represents the second surface outlet temperature of the air conditioner evaporator. It should be noted that T... 设 It is generally an integer value between 18 and 32.

[0070] In one embodiment, determining the air conditioner's output temperature based on the air conditioner's set temperature and the outlet air temperature reference value corresponding to the target operating device type includes:

[0071] When the target working device type is a compressor and a heat pump, the third surface outlet temperature of the heat pump heat exchanger corresponding to the second preset percentage state of the compressor in the maximum cooling state and the third preset percentage state of the heat pump in the maximum heat release state is obtained, and the fourth surface outlet temperature of the heat pump heat exchanger corresponding to the second preset percentage state of the compressor in the maximum cooling state and the third preset percentage state of the heat pump in the maximum heat release state is obtained.

[0072] Based on the air outlet temperatures of the third and fourth surfaces, the actual surface air outlet temperatures of the heat pump heat exchanger at the air conditioning set temperature are calculated and used as the output temperature of the air conditioner.

[0073] The specific calculation formula is as follows:

[0074]

[0075] Among them, T 设 Set the temperature for the air conditioner; T 热泵 T1 represents the actual surface outlet temperature of the heat pump heat exchanger; T4 represents the third surface outlet temperature of the heat pump heat exchanger; and T2 represents the fourth surface outlet temperature of the heat pump heat exchanger. It should be noted that T... 设 It is generally an integer value between 18 and 32.

[0076] Furthermore, when the target operating device is a heat pump, the actual surface outlet air temperature of the heat pump heat exchanger is:

[0077]

[0078] Among them, T 设 Set the temperature for the air conditioner, T 设 Generally, it is an integer value between 18 and 32; T 热泵 T6 is the actual surface outlet temperature of the heat pump heat exchanger; T5 is the surface outlet temperature of the heat pump heat exchanger corresponding to the maximum heat release state of the heat pump; T6 is the surface outlet temperature of the heat pump heat exchanger corresponding to the state of 10% of the maximum heat release state of the heat pump.

[0079] When the electric auxiliary heating device PTC is working, the actual surface outlet air temperature of the heater is:

[0080]

[0081] Among them, T 设 Set the temperature for the air conditioner, T 设 Generally, it is an integer value between 18 and 32; T 加 T8 is the actual surface outlet temperature of the heater; T7 is the surface outlet temperature of the heater corresponding to the maximum heat release state of the PTC; T8 is the surface outlet temperature of the heater corresponding to the state of maximum heat release * 10% of the PTC.

[0082] In the method provided in the above embodiments, the air conditioning output temperature is calculated using a specific formula, which can reduce the amount of calculation, quickly respond to the driver's temperature needs, and improve the user experience.

[0083] In one embodiment, obtaining the first surface outlet air temperature of the air conditioner evaporator when the compressor is in maximum cooling condition includes:

[0084] Set the compressor to maximum cooling mode and conduct at least one test at different ambient temperatures to obtain the air outlet temperature of the test surface of the air conditioner evaporator.

[0085] The first surface outlet temperature of the air conditioner evaporator is obtained by weighted averaging the air outlet temperature of the test surface corresponding to each test.

[0086] It should be noted that T1 to T8 in the above embodiments can all be determined experimentally using the method provided in this embodiment. When processing the experimental data, it is not limited to weighted average processing; the average value can be calculated directly, or other data processing methods can be adopted to obtain representative reference values.

[0087] In the method provided in the above embodiments, by conducting a large number of tests in advance to determine the reference values ​​in each formula, the amount of calculation in the temperature determination process can be reduced, and the output temperature of the air conditioner can be determined quickly.

[0088] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
