[0002] The air conditioning cold start function refers to the automatic activation of the air conditioning system as soon as the vehicle is started when the ambient temperature is low. Currently, when the car air conditioning performs a cold start in a cold environment, the cold air blows directly onto the body of the passengers, which is a very unpleasant experience. Summary of the Invention

[0006] Periodically collect the air conditioner's outlet temperature, air volume, voltage, and in-vehicle humidity;

[0007] The comfort index is determined based on the outlet air temperature, outlet air volume voltage, vehicle humidity, and the temperature difference between the current and previous collection cycles.

[0008] Based on the comfort index, the corresponding air conditioning cold start control mode is activated.

[0009] Preferably, the step of determining the comfort index based on the outlet air temperature, outlet air volume voltage, in-vehicle humidity, and the temperature difference between the current and previous collection cycles includes:

[0010] The comfort index is obtained by weighting the air outlet temperature, air volume voltage, vehicle humidity, and the temperature difference between the current and previous collection cycles.

[0011] Preferably, the step of entering the corresponding air conditioning cold start control mode according to the comfort index includes:

[0012] If the comfort index is less than the first preset threshold, the air conditioner enters the cold start rapid heating mode, specifically: the air conditioner's air outlet mode is set to window blowing mode, the air conditioner's circulation mode is set to internal circulation, and the air volume of the air conditioner's blower is set to the minimum value.

[0013] If the comfort index is greater than or equal to the first preset threshold and less than the second preset threshold, the air conditioner enters the cold start comfort transition mode, specifically: the air conditioner's air outlet mode is set to foot blowing mode, the air conditioner's circulation mode is set to internal circulation mode, and the air volume of the air conditioner's blower is set to the sum of the minimum value and the set air volume.

[0014] Preferably, the set air volume is determined jointly based on the predetermined blower target voltage corresponding to the air conditioner cold start comfort transition mode, the comfort index determined in the current collection cycle, and the comfort index determined in the previous collection cycle.

[0015] Preferably, if the comfort index is greater than or equal to the second preset threshold, the air conditioner cold start control mode is exited and the air conditioner steady-state control mode is entered; the air conditioner steady-state control mode specifically means: in response to the user's settings for air outlet mode, circulation mode and / or air outlet temperature, the air conditioning system is adjusted accordingly.

[0016] Preferably, before the step of periodically collecting the air outlet temperature, air outlet volume, voltage, and in-vehicle humidity of the air conditioner, the method further includes:

[0017] Determine if this is the first cold start of the air conditioning system after the vehicle rolls off the production line;

[0018] If this is the first time the air conditioning has been cold-started after the vehicle has rolled off the production line, select the heat source mode that corresponds to the vehicle's model configuration information;

[0019] Based on the heat source combination mode, the corresponding software control logic is selected for air conditioner cold start control.

[0020] This application also provides an air conditioner cold start control device, including:

[0021] The data acquisition module is used to periodically collect the air outlet temperature, air outlet volume, voltage, and in-vehicle humidity of the air conditioner.

[0022] The comfort index determination module is used to determine the comfort index based on the outlet air temperature, outlet air volume voltage, vehicle humidity, and the temperature difference between the outlet air temperature in the current collection cycle and the previous collection cycle.

[0023] The air conditioner cold start control mode entry module is used to enter the corresponding air conditioner cold start control mode based on the comfort index.

[0024] Preferably, the comfort index determination module includes:

[0025] The comfort index determination unit is used to perform weighted processing based on the outlet air temperature, outlet air volume voltage, vehicle humidity, and the temperature difference between the current and previous collection cycles to obtain the comfort index.

[0026] Preferably, the air conditioner cold start control mode entry module includes:

[0027] The first entry unit is used to enter the air conditioner cold start rapid heating mode if the comfort index is less than the first preset threshold. Specifically, it controls the air conditioner's air outlet mode to window blowing mode, controls the air conditioner's circulation mode to internal circulation, and controls the air conditioner's blower air volume to the minimum value.

[0028] The second entry unit is used to enter the air conditioner cold start comfort transition mode if the comfort index is greater than or equal to the first preset threshold and less than the second preset threshold. Specifically, it controls the air conditioner's air outlet mode to foot blowing mode, controls the air conditioner's circulation mode to internal circulation mode, and controls the air conditioner's blower air volume to the sum of the minimum value and the set air volume.

[0029] This application also provides a vehicle including the aforementioned air conditioning cold start control device.

[0030] The beneficial effects of this invention are as follows:

[0031] By periodically collecting data on air temperature, air volume, voltage, humidity, and temperature difference change rate, the system quantifies the three-dimensional real-time status of heat, airflow, and humidity into a comfort index, forming a closed-loop perception-feedback link. This enables the control logic to accurately approach the comfort zone in each cycle with the lowest energy consumption, the most stable wind speed, and the shortest path, thereby eliminating sudden temperature changes, glass fogging, and a sharp increase in noise in principle, and significantly improving the perceived comfort during the cold start phase.

[0032] Through the three-element binding architecture of vehicle model-heat source mode-control logic, the unique heat source mode corresponding to the platform and vehicle model is automatically identified during the first cold start of the air conditioning after the vehicle rolls off the production line, and its exclusive control parameters and algorithms are loaded in real time. This enables plug-and-play thermal management strategies across platforms and vehicle models without any software redevelopment, ensuring that defrosting, heating, energy consumption and NVH performance meet the design targets on the first start.

[0037] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings. While the description is quite detailed, it should not be construed as limiting the scope of the present invention. Obvious variations and substitutions of the following examples are all within the scope of protection of this patent.

[0038] Reference Figure 1 This application provides an air conditioner cold start control method, including:

[0039] S101 periodically collects the air outlet temperature, air volume, voltage, and in-vehicle humidity of the air conditioner;

[0040] S102, determine the comfort index based on the outlet air temperature, outlet air volume voltage, vehicle humidity, and the temperature difference between the current collection cycle and the previous collection cycle.

[0041] S103, based on the comfort index, enter the corresponding air conditioning cold start control mode.

[0042] The outlet air temperature is collected by a temperature sensor, which is used to collect the outlet air temperature in the passenger compartment; the vehicle humidity is collected by a humidity sensor. The outlet air volume voltage is the voltage difference between the positive and negative terminals of the blower, which is obtained by a voltage acquisition device, such as that of a power management system.

[0043] In this embodiment of the application, step S102, which determines the comfort index based on the outlet air temperature, outlet air volume voltage, in-vehicle humidity, and the temperature difference between the current and previous collection cycles of the outlet air temperature, includes:

[0044] S1021, the comfort index is obtained by weighting the air outlet temperature, air outlet volume voltage, vehicle humidity, and the temperature difference between the current and previous collection cycles.

[0045] Specifically, using the formula CI=k1*T out +k2*V out +k3*RH+k4*(T out -T out-1 The comfort index CI is calculated using a formula based on the outlet air temperature T. out Air volume and voltage V out The vehicle interior humidity (RH) and the temperature difference between the current and previous air outlet temperatures (T) are also important factors. out -T out-1 The results are obtained by weighting the calculations with different proportional coefficients k1, k2, k3, and k4 respectively; where the first proportional coefficient k1, the second proportional coefficient k2, the third proportional coefficient k3, and the fourth proportional coefficient k4 are all preset coefficient values.

[0046] In this embodiment of the application, step S103, which involves entering the corresponding air conditioning cold start control mode based on the comfort index, includes:

[0047] If the comfort index is less than the first preset threshold, the air conditioner enters the cold start rapid heating mode, specifically: the air conditioner's air outlet mode is set to window blowing mode, the air conditioner's circulation mode is set to internal circulation, and the air volume of the air conditioner's blower is set to the minimum value.

[0048] If the comfort index is greater than or equal to the first preset threshold and less than the second preset threshold, the air conditioner enters the cold start comfort transition mode, specifically: the air conditioner's air outlet mode is set to foot blowing mode, the air conditioner's circulation mode is set to internal circulation mode, and the air volume of the air conditioner's blower is set to the sum of the minimum value and the set air volume.

[0049] When the comfort index falls below the first preset threshold, it indicates that the current in-vehicle environment is very uncomfortable. The highest priority is to raise the average cabin temperature to a safe level as quickly as possible, thus immediately activating the air conditioning cold start rapid warm-up mode. In this mode, the airflow direction is locked to window blowing mode, concentrating warm air onto the windshield and side windows. This quickly melts frost and fog on the glass surface and utilizes the glass's heat capacity to create a radiant heat source. Simultaneously, the system switches to internal circulation to cut off the continuous infiltration of cold air from outside, creating a "smoldering" effect in the enclosed cabin and significantly shortening the time it takes for the air temperature to rise. At the same time, the blower fan speed is reduced to the lowest setting, minimizing blower noise and preventing cold air from directly blowing on occupants, while allowing heat to slowly and evenly diffuse throughout the cabin, preventing heat from being quickly carried away by high-speed airflow. This achieves a balance between defogging, heat preservation, and quiet operation at the initial startup stage.

[0050] When the comfort index is between the first and second preset thresholds, it indicates that the current in-car environment is relatively acceptable, thus switching to the air conditioning cold start comfort transition mode. In this mode, the airflow direction automatically adjusts to a foot-blowing mode, allowing warm, low-speed airflow to first cover the feet and calves—areas most susceptible to cold—to rapidly warm up the area and alleviate the feeling of cold. The recirculation mode maintains internal circulation, continuing to block the intrusion of cold air from outside while efficiently recovering heat from the pre-warmed in-car air. The blower airflow is increased by a small increment on top of the minimum safe speed, making the airflow slightly higher than the lowest setting. This ensures that the feet quickly receive gentle warm air while avoiding the discomfort and noise caused by direct airflow at high speeds, achieving a fine balance between energy saving, quietness, and localized comfort, laying a foundation for a comfortable ride during the subsequent full-scale warming phase.

[0051] In this embodiment of the application, the set air volume is determined jointly based on the predetermined blower target voltage corresponding to the air conditioner cold start comfort transition mode, the comfort index determined in the current collection cycle, and the comfort index determined in the previous collection cycle.

[0052] Specifically, through K*(CI-CI) -1 The target voltage of the blower determines the value of the aforementioned set air volume. Wherein, (CI-CI) -1 The value represents the comfort index determined in the current data collection cycle and the comfort index determined in the previous data collection cycle. The target voltage of the blower is the voltage value required for the thermal balance of the vehicle in the current state.

[0053] The predetermined blower target voltage is used to limit the maximum air volume of the blower in the air conditioning cold start comfort transition mode; that is, in the air conditioning cold start comfort transition mode, when the blower's operating voltage reaches the blower target voltage, the blower's air volume reaches its maximum, and thereafter, the blower's air volume will not increase by the set air volume.

[0054] In this embodiment, if the comfort index is greater than or equal to a second preset threshold, the air conditioning cold start control mode is exited, and the air conditioning steady-state control mode is entered. Specifically, the air conditioning steady-state control mode involves adjusting the air conditioning system in response to user settings for airflow mode, circulation mode, and / or airflow temperature. In other words, in this mode, the in-vehicle environment is already comfortable, therefore, the system directly responds to user needs using conventional control methods.

[0055] Reference Figure 2 In this embodiment of the application, before performing step S101, the method further includes:

[0056] S104, determine whether this is the first cold start of the air conditioning after the vehicle rolls off the production line;

[0057] For S105, if this is the first cold start of the air conditioning after the vehicle rolls off the production line, select the heat source mode corresponding to the vehicle's model configuration information.

[0058] S106, Based on the heat source combination mode, select the corresponding software control logic to perform air conditioner cold start control.

[0059] Specifically, in this embodiment of the application, before periodically collecting the air outlet temperature, air outlet volume, voltage, and in-vehicle humidity of the air conditioner, the method first performs the following preliminary steps:

[0060] By reading the first power-on flag of the vehicle controller VCU or the "first start" flag written by the production line, it can be determined whether this is the first cold start of the air conditioning after the vehicle rolls off the production line.

[0061] If it is determined to be the first start, the calibration table will be searched and the unique corresponding heat source mode (e.g., "engine coolant + PTC in parallel" or "heat pump + battery waste heat recovery") will be locked according to the vehicle configuration information (such as engine type, PTC power, presence or absence of heat pump, battery heating circuit, etc.).

[0062] Based on the locked heat source mode, the software control logic bound to it (including initial valve opening, water pump speed, compressor start-up curve, blower minimum air volume mapping table and rapid demisting strategy) is loaded, and then the periodic sensor data acquisition stage is entered.

[0063] By employing steps S104-S106 above, without remodeling or modifying the underlying algorithm, precise control can be achieved during the first cold start of the air conditioning system after the vehicle rolls off the production line simply by calling the control logic and parameter table (initial valve opening value, water pump speed curve, compressor start-up gradient, blower minimum airflow mapping, etc.) bound to the identified heat source combination mode. This mechanism enables plug-and-play automatic adaptation across different platforms and vehicle models, even with significant differences in thermal management architecture. It eliminates redundant software model development and ensures that initial start-up performance, energy consumption, and NVH indicators meet the acceptance standards of their respective platforms.

[0064] During the research and development process, the heat source status of all vehicle models includes existing heat pumps, PTCs, engine waste heat, heat pump + PTC, heat pump + engine waste heat, PTC + engine waste heat, and heat pump + PTC + engine waste heat. By developing a defined system architecture and corresponding configuration codes, the corresponding heat source status is calculated and output.

[0069] Preferably, the comfort index determination module 102 includes:

[0070] The comfort index determination unit 1021 is used to perform weighted processing based on the outlet air temperature, outlet air volume voltage, vehicle humidity, and the temperature difference between the outlet air temperature in the current collection cycle and the previous collection cycle to obtain the comfort index.
