Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an automobile air-conditioning control method, a vehicle processor, a device and a storage medium. Background Art

[0002] As a core device to ensure the comfort of the in-car environment, the temperature control accuracy of the automobile air-conditioning system directly affects the passenger experience. Existing automobile air-conditioning systems generally adopt a single-point temperature detection and centralized control strategy, which collects the overall temperature signal by installing a single temperature sensor at a specific location in the car, and uniformly adjusts the air-conditioning power and the air outlet opening based on the signal. However, this control method is difficult to meet the precision requirements under complex working conditions. The core technical features of the existing system are single-point temperature detection and centralized control logic: it only relies on a single sensor to obtain the average temperature in the car, and uniformly adjusts the air-conditioning parameters through a fixed algorithm, so that all seats share the same cooling / heating intensity.

[0003] However, the study found that this technical solution has the following defects: First, single-point detection cannot cover the temperature differences in different areas within the vehicle, and it is difficult to capture local thermal disturbances (such as engine heat radiation or direct sunlight), resulting in deviations between the control strategy and actual needs; second, the sensor is susceptible to environmental interference, resulting in data distortion, and is unable to distinguish the differentiated contributions of different heat sources; third, the adjustment method based on average temperature is difficult to meet personalized needs, and has a delayed response to sudden temperature changes; fourth, in order to compensate for local high-temperature areas, the system needs to continue to operate at high power, resulting in over-adjustment and energy waste in low-temperature areas.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0022] Embodiment 1: To facilitate understanding of this application, Figure 1 The flowchart of the automobile air-conditioning control method provided by the first embodiment of the present invention is shown to describe the contents of the first embodiment of the present application in detail.

[0023] See also Figure 1 As shown, Figure 1 A flow chart of an automobile air-conditioning control method provided in a first embodiment of the present invention is shown, wherein the method is applied to an automobile air-conditioning control system, the system comprising a plurality of first sensors for collecting seat temperatures at different automobile seats, a plurality of second sensors for collecting light intensity at automobile windows on different sides, and a third sensor for collecting engine temperature of an automobile engine, and the automobile air-conditioning control method runs in a vehicle processor.

[0024] Specifically, the method is applied to a specific automobile air conditioning control system, in which different types of sensors are equipped. Several first sensors are responsible for collecting seat temperatures at different car seats, several second sensors are used to collect light intensity at different side car windows, and the third sensor is specifically used to collect the engine temperature of the car engine. These sensors will collect data according to a preset collection cycle. After the vehicle processor obtains the initial seat temperature at each car seat, the light intensity at each side car window, and the engine temperature, the subsequent control process is started.

[0025] The method comprises steps S101 to S105: S101: After obtaining the initial seat temperature of each vehicle seat, the light intensity at each side vehicle window and the engine temperature collected by each first sensor, each second sensor and the third sensor according to a preset collection period, determine the first temperature compensation amount at each vehicle seat affected by the engine temperature based on the engine temperature and the first straight-line distance between the vehicle engine and each vehicle seat.

[0026] Specifically, this step determines the first temperature compensation amount of each seat affected by the engine temperature based on the engine temperature and the first straight-line distance between the car engine and each car seat. The engine generates heat during operation, and the heat it dissipates will affect the temperature of the surrounding seats, and the degree of this influence is related to the distance between the engine and the seat. The closer the seat is to the engine, the greater the influence of the engine heat, and the corresponding first temperature compensation amount is greater. By comprehensively considering the engine temperature and the first straight-line distance, the specific degree of influence of the engine heat on the temperature of each seat can be more accurately evaluated, thereby determining the appropriate first temperature compensation amount.

[0027] S102: Determine a second temperature compensation amount at each vehicle seat affected by the light intensity based on the light intensity at each vehicle window and a second straight-line distance between each vehicle window and the vehicle seat on the same side.

[0028] Specifically, this step determines the second temperature compensation amount of each seat affected by the light intensity based on the light intensity at the car windows on each side and the second straight-line distance between the car windows on each side and the car seats on the same side. When sunlight shines on the car windows, the light will enter the car through the windows, causing the temperature inside the car to rise, especially the seats close to the windows are more significantly affected by the light. The greater the light intensity and the closer the distance between the seat and the window, the higher the degree of light heating of the seat, and the greater the corresponding second temperature compensation amount. By analyzing the two factors of light intensity and the second straight-line distance, the effect of light on the temperature of each seat can be calculated more accurately, and then the corresponding second temperature compensation amount can be determined.

[0029] S103: Determine an overall temperature compensation amount for each seat position based on a first temperature compensation amount at each vehicle seat affected by the engine temperature and a second temperature compensation amount at each vehicle seat affected by the light intensity.

[0030] Specifically, this step is to determine the overall temperature compensation at each seat position based on the first temperature compensation amount affected by the engine temperature and the second temperature compensation amount affected by the light intensity at each car seat. In the actual car environment, the actual temperature change of the seat is the result of the combined effect of multiple factors such as engine heat dissipation and light heating. Therefore, it is necessary to comprehensively consider the first temperature compensation amount and the second temperature compensation amount to obtain an overall temperature compensation amount that accurately reflects the actual temperature change of each seat, providing a reliable basis for the subsequent accurate control of the air outlet of the air conditioner.

[0031] S104: Determine the target opening of the vehicle air conditioning duct opening corresponding to each vehicle seat based on the initial seat temperature of each vehicle seat and the overall temperature compensation amount.

[0032] Specifically, this step determines the target opening of the air duct opening of the automobile air conditioner corresponding to each seat according to the initial seat temperature and the overall temperature compensation at each seat. The initial seat temperature reflects the original temperature state of the seat without considering the influence of the engine and light, while the overall temperature compensation reflects the additional influence of the engine and light on the seat temperature. By combining these two data, the actual degree of cooling or heating required for each seat can be accurately determined, and then the corresponding target opening of the air duct opening of the air conditioner can be determined. For example, for seats with higher temperatures, the opening of the air duct opening needs to be increased to provide more cold air; for seats with lower temperatures, the opening of the air duct opening should be appropriately reduced.

[0033] S105: Controlling each automobile air-conditioning duct opening according to the target opening of each automobile air-conditioning duct opening.

[0034] Specifically, the last step is to control the car air conditioner according to the target opening of each car air conditioner duct. After determining the target opening of the air conditioner duct corresponding to each seat, the vehicle processor will send corresponding control instructions to the car air conditioning system to adjust the actual opening of each duct so that the air volume output by the air conditioner can be distributed according to the actual needs of different seats, thereby achieving precise adjustment of the temperature at different seats in the car and creating a more comfortable riding environment for passengers.

[0035] In an alternative embodiment, see Figure 2 As shown, Figure 2 A flow chart of a method for determining a first temperature compensation amount provided in the first embodiment of the present invention is shown, wherein the first temperature compensation amount at each vehicle seat affected by the engine temperature is determined based on the engine temperature and the first straight-line distance between the vehicle engine and each vehicle seat, including steps S201 to S203: S201: Determine the equivalent additional distance of each vehicle seat according to the thermal conductivity and thickness of the structural material of each vehicle seat.

[0036] Specifically, car seats are made of different structural materials, and the thermal conductivity of different materials varies. Thermal conductivity reflects the ability of a material to conduct heat. The higher the thermal conductivity, the easier it is for the material to conduct heat; the lower the thermal conductivity, the more difficult it is. At the same time, the thickness of the seat will also affect the heat conduction process. Thicker seats will have greater resistance when heat is transferred.

[0037] Taking into account the thermal conductivity and thickness of the seat structure material, an equivalent added distance can be determined. This equivalent added distance is a quantitative representation of the effect of the seat material and thickness on heat transfer. For example, if a seat is made of a material with low thermal conductivity and thicker, its equivalent added distance will be relatively large, which means that the heat transfer from the engine to this seat will be more hindered.

[0038] Furthermore, define Equivalent additional distance for car seats , to reflect the engine compartment and the The comprehensive thermal resistance of the multi-layer structure between the car seats: × ; in, For the Car seat number The thickness of the layer structure materials (such as metal plates, insulation wool, etc.); For the Car seat number Thermal conductivity of the layered material (≈50 W / m·K for metals and ≈0.2 W / m·K for plastics); is the structural thermal resistance correction coefficient, ∈[1,N1], N1 is the number of car seats, is an integer, ∈[1,N2], N2 is the number of layers of structural material, is an integer.

[0039] S202: Determine the equivalent distance between the vehicle engine and each vehicle seat according to the equivalent additional distance of each vehicle seat and the first straight-line distance between the vehicle engine and each vehicle seat.

[0040] Specifically, after obtaining the equivalent additional distance of each car seat, it is combined with the first straight-line distance between the car engine and each car seat to calculate the equivalent distance between the engine and each seat. The first straight-line distance is the direct distance between the engine and the seat in space, while the equivalent additional distance takes into account the effect of the seat material and thickness on heat conduction.

[0041] The equivalent distance obtained by adding the two together more accurately reflects the "effective distance" that the engine heat actually travels to transfer to the seat. For example, although the first straight-line distance between the two seats and the engine is the same, their equivalent additional distances are different, so the final equivalent distances will also be different, which will affect the actual impact of the engine heat on the two seats.

[0042] Further, Equivalent distance of car seats The expression of the equivalent thermal radiation distance after comprehensive structural isolation is: = + ; in, For the engine and The first straight-line distance of the car seats; For automobile engines and The equivalent additional distance of a car seat.

[0043] S203: Determine a first temperature compensation amount for each vehicle seat affected by the engine temperature according to an equivalent distance between the vehicle engine and each vehicle seat and the engine temperature.

[0044] Specifically, after determining the equivalent distance between the engine and each car seat, combined with the engine temperature, the first temperature compensation amount of each seat affected by the engine temperature can be determined. Generally speaking, the higher the engine temperature and the closer the equivalent distance between the engine and the seat, the greater the impact of the engine heat on the seat temperature, and the corresponding first temperature compensation amount is greater. By establishing a mathematical model or formula, the first temperature compensation amount is calculated based on the equivalent distance and engine temperature. This compensation amount can reflect the change in the temperature of each seat due to engine heat dissipation compared to when there is no engine heat influence, providing an important basis for the subsequent accurate adjustment of the car air conditioner.

[0045] Furthermore, the following model is used to determine the The first temperature compensation value affected by the engine temperature at each car seat : × ; in, is the air thermal attenuation coefficient (typical value 0.2 / m); The real-time temperature of the engine (e.g. 95°C); For the The equivalent distance of a car seat.

[0046] For example, suppose the parameters of a vehicle model are as follows: engine temperature =95∘C; the straight-line distance from a seat to the engine = 0.8m, the structural layer includes 5mm metal plate ( =0.005m, =50W / m·K) and 20mm thermal insulation cotton ( =0.02m, =0.05W / m·K). Then: The equivalent additional distance of the seat: =500.005× +0.050.02× =0.405m. Equivalent distance: =0.8+0.405=1.205m. The first temperature compensation =95× ≈95×0.852=80.9℃.

[0047] In an alternative embodiment, see Figure 3 As shown, Figure 3 A flow chart of a second temperature compensation method provided in the first embodiment of the present invention is shown, wherein the second temperature compensation amount at each vehicle seat affected by the light intensity is determined based on the light intensity at the vehicle windows on each side and the second straight-line distance between the vehicle windows on each side and the vehicle seats on the same side, including steps S301-S303: S301: Determine a first temperature change amount of a vehicle seat on the same side affected by air heating according to the light intensity at the vehicle windows on each side and the air light and heat absorption coefficient.

[0048] Specifically, when sunlight enters the car through the car windows, it heats the air inside the car. Light intensity is an indicator of the amount of sunlight energy. The greater the light intensity, the more light energy enters the car through the car windows per unit time. The air light and heat absorption coefficient reflects the ability of air to absorb light energy and convert it into heat energy.

[0049] By combining the light intensity at the car windows on each side with the air light and heat absorption coefficient, the first temperature change at the car seat on the same side affected by air heating can be calculated. This is because in the process of converting light energy into heat energy, the air absorbs light energy and the temperature rises, which in turn affects the temperature around the seat. The greater the light intensity and the air light and heat absorption coefficient, the more light energy the air absorbs and the more the temperature rises, which increases the temperature change at the seat caused by air heating.

[0050] Furthermore, the following expression is used to determine The first temperature change at each car seat affected by air heating : ; in, is the light and heat absorption coefficient of air; For the The light intensity of the car window on the same side of the car seat is The first car seat is a left-side seat, then Take the light intensity at the left car window. The first car seat is a right-hand seat, then Take the light intensity at the right car window.

[0051] S302: Determine a second temperature change at each vehicle seat affected by radiation heating from an object according to the light intensity at each vehicle window, the second straight-line distance between each vehicle window and the vehicle seat on the same side, and the light radiation distance attenuation coefficient.

[0052] Specifically, when sunlight hits the surface of an object, it transfers energy to the object in the form of radiation, causing the object's temperature to rise, which in turn affects the temperature of the surrounding environment. Inside a car, sunlight shines through the side window onto the seat on the same side, causing the seat to be affected by radiation heating from the object. In this process, the light intensity determines the amount of radiation energy. The greater the light intensity, the stronger the radiation energy. The second straight-line distance between the car windows on each side and the car seats on the same side will affect the transfer effect of the radiation energy. The farther the distance, the more the radiation energy attenuates during the transfer process. The light radiation distance attenuation coefficient is a parameter used to describe the degree of attenuation of radiation energy with distance.

[0053] By comprehensively considering the light intensity, the second straight-line distance and the light radiation distance attenuation coefficient, the second temperature change at each car seat affected by the radiation heating of the object can be calculated. As the light intensity increases, the second straight-line distance decreases and the light radiation distance attenuation coefficient decreases, the radiation heating effect of the object on the seat will be more obvious, and the second temperature change will be greater.

[0054] Further, the following expression is used to determine The second temperature change at the car seat affected by the radiation heating of the object :

[0055] in, The light-to-heat conversion efficiency of an object (such as a leather seat =0.03℃ / (W / m2), fabric seat =0.05℃ / (W / m2)); is the light radiation distance attenuation coefficient; For the The second straight-line distance between a car seat and the car window on the same side; For the The light intensity at the car window on the same side of the car seat is The first car seat is a left-side seat, then Take the light intensity at the left car window. The car seat is the right seat, then Take the light intensity at the right car window.

[0056] S303: Determine a second temperature compensation amount for each vehicle seat affected by the light intensity according to the first temperature change amount affected by air heating and the second temperature change amount affected by object radiation heating.

[0057] Specifically, the temperature change at the car seat affected by the light intensity is the result of the combined effect of air heating and object radiation heating. Therefore, it is necessary to comprehensively consider the first temperature change amount affected by air heating and the second temperature change amount affected by object radiation heating at each car seat to determine the second temperature compensation amount affected by the light intensity at each car seat.

[0058] Specifically, the first temperature change and the second temperature change can be added or combined according to a certain weight to obtain the final second temperature compensation. This compensation reflects the actual temperature change of the seat due to the effect of light intensity, and provides an important basis for the subsequent precise adjustment of the car air conditioner according to the actual temperature requirements of different seats.

[0059] Further, the following expression is used to determine The second temperature compensation value affected by the light intensity at the car seat ; ; in, For the The first temperature change at each car seat affected by air heating, For the The second temperature change at each car seat affected by radiation heating from the object.

[0060] In an alternative embodiment, see Figure 4 As shown, Figure 4 A flow chart of a method for determining an overall temperature compensation amount provided by the first embodiment of the present invention is shown, wherein the overall temperature compensation amount for each seat position is determined based on a first temperature compensation amount at each vehicle seat affected by the engine temperature and a second temperature compensation amount at each vehicle seat affected by the light intensity, including steps S401 to S403: S401: respectively configuring a first influence weight and a second influence weight for the influence of the engine temperature and the influence of the light intensity.

[0061] Specifically, in an actual car environment, the influence of engine temperature and light intensity on car seat temperature is not fixed, but is affected by multiple factors, such as the driving state of the car, the lighting conditions of the environment, etc. In order to more accurately measure the influence of these two factors on seat temperature, it is necessary to configure the first influence weight and the second influence weight for the engine temperature influence and the light intensity influence respectively.

[0062] The first impact weight reflects the proportion of engine temperature in the overall temperature impact, and the second impact weight reflects the impact of light intensity. For example, during a sunny day, light intensity may have a greater impact on seat temperature, and the second impact weight will be relatively high; when the car is driving at high speed for a long time, the engine generates more heat, which has a more significant impact on seat temperature, and the first impact weight may increase.

[0063] S402: Determine a first local temperature compensation amount at each vehicle seat affected by the engine temperature according to the first temperature compensation amount at each vehicle seat affected by the engine temperature and the first influence weight.

[0064] Specifically, after determining the first influence weight, combined with the first temperature compensation amount affected by the engine temperature at each car seat, the first local temperature compensation amount affected by the engine temperature of each seat can be calculated. The first temperature compensation amount represents the original degree of influence of the engine temperature on the seat temperature, and the first influence weight makes a quantitative adjustment to this influence. The specific calculation method is to multiply the first temperature compensation amount by the first influence weight. In this way, it can more accurately reflect the actual temperature impact of the engine temperature on each seat after comprehensively considering various factors, and provide more accurate data for the subsequent calculation of the overall temperature compensation amount.

[0065] Further, the following expression is used to determine A first local temperature compensation value at a vehicle seat affected by the engine temperature : × ; in, is the first impact weight, For the A first temperature compensation amount affected by the engine temperature at each vehicle seat.

[0066] S403: Determine a second local temperature compensation amount affected by the light intensity at each vehicle seat according to the second temperature compensation amount affected by the light intensity at each vehicle seat and the second influence weight.

[0067] Specifically, similarly, for the influence of light intensity, after obtaining the second influence weight, combined with the second temperature compensation amount affected by the light intensity at each car seat, the second local temperature compensation amount affected by the light intensity of each seat can be calculated. The second temperature compensation amount reflects the initial influence of light intensity on the seat temperature, and the second influence weight makes a reasonable adjustment to it. The calculation method is to multiply the second temperature compensation amount by the second influence weight. In this way, the actual influence of light intensity on the temperature of each seat in the overall environment can be measured more accurately.

[0068] Further, the following expression is used to determine A second local temperature compensation value at a vehicle seat affected by the light intensity : ; in, is the second impact weight, For the A second temperature compensation amount affected by light intensity at each car seat.

[0069] S404: Determine the overall temperature compensation amount of each vehicle seat according to the first local temperature compensation amount and the second local temperature compensation amount of each vehicle seat.

[0070] Specifically, the actual temperature change at each car seat is the result of the combined effect of the engine temperature and the light intensity. Therefore, the overall temperature compensation at each car seat can be obtained by adding the first local temperature compensation amount and the second local temperature compensation amount of each seat.

[0071] The overall temperature compensation takes into account the impact of the two main factors, engine temperature and light intensity, on the seat temperature, and can more accurately reflect the actual temperature adjustment required by the seat, providing a key basis for the automotive air conditioning system to accurately control the temperature according to the specific conditions of different seats. For example, for seats with a large overall temperature compensation, the air conditioner can appropriately increase the air volume or reduce the air temperature to meet the comfort needs of the passengers in that seat.

[0072] Further, the following expression is used to determine Overall temperature compensation at each car seat : + ; in, For the A first local temperature compensation amount at each vehicle seat affected by the engine temperature, For the A second local temperature compensation amount affected by the light intensity at each vehicle seat.

[0073] In an alternative embodiment, see Figure 5 As shown, Figure 5 The flowchart of the target opening determination method provided in the first embodiment of the present invention is shown, wherein the target opening of the automobile air conditioning duct outlet corresponding to each automobile seat is determined based on the initial seat temperature and the overall temperature compensation amount at each automobile seat, including steps S501 to S503: S501: Determine the initial control opening of the automobile air conditioning duct opening corresponding to each automobile seat according to the feedforward proportional coefficient and the overall temperature compensation amount at each automobile seat.

[0074] Specifically, the overall temperature compensation reflects the combined effect of external factors such as engine temperature and light intensity on the temperature of each car seat. The feedforward proportional coefficient is a pre-set parameter that establishes the corresponding relationship between the overall temperature compensation and the initial control opening of the air conditioning duct outlet. By multiplying the feedforward proportional coefficient with the overall temperature compensation at each car seat, the initial control opening of the car air conditioning duct outlet corresponding to each car seat can be obtained. This feedforward control-based method can make preliminary adjustments to the air conditioning duct outlet opening in advance based on known external interference factors (such as engine heat dissipation and light) to reduce the impact of these factors on the seat temperature.

[0075] Further, the following expression is used to determine The initial control opening of the air duct of the car air conditioner corresponding to each car seat : = × ; in, is the feedforward proportional coefficient (example: 10% / , that is, every degree Celsius temperature difference corresponds to a 10% opening change). For the Overall temperature compensation at each car seat.

[0076] S502: Determine the optimized control opening of the automobile air conditioning duct opening corresponding to each automobile seat according to the first control opening of the automobile air conditioning duct opening corresponding to each automobile seat, the automobile air conditioning set temperature and the initial seat temperature of each automobile seat.

[0077] Specifically, the initial control opening is a preliminary adjustment value based on feedforward control, but it does not fully consider the deviation between the current actual seat temperature and the set temperature. The car air conditioning set temperature is the comfort temperature that the user expects to achieve, and the initial seat temperature at each car seat represents the current actual temperature. By comparing these two temperatures and the initial control opening, using a specific control algorithm (such as PID algorithm) to optimize and adjust the initial control opening, the seat temperature can be more accurately brought close to the set temperature.

[0078] Further, the following expression is used to determine Optimized control of the opening of the air duct of the automobile air conditioner corresponding to each car seat : ; in, For the The initial control opening of the air duct of the car air conditioner corresponding to each car seat, Set the temperature for your car's air conditioner, For the Initial seat temperature at each vehicle seat.

[0079] S503: Determine the target opening of the automobile air-conditioning duct opening corresponding to each automobile seat according to the optimized control opening of the automobile air-conditioning duct opening corresponding to each automobile seat and the opening limit of the automobile air-conditioning duct opening.

[0080] Specifically, to ensure the safe and stable operation of the automobile air conditioning system, the control opening of each automobile air conditioning duct outlet has a limit range, that is, the opening cannot exceed this range. After obtaining the optimized control opening of the automobile air conditioning duct outlet corresponding to each automobile seat, it is necessary to compare it with the opening limit of the automobile air conditioning duct outlet. If the optimized control opening is within the limit range, it is used as the target opening; if the optimized control opening exceeds the limit range, it is adjusted to the limit boundary value, that is, the maximum opening limit is used as the target opening.

[0081] Further, the following expression is used to determine The target opening of the air duct of the automobile air conditioner corresponding to each automobile seat : =min(max( , ), ); in, For the The optimized control opening of the air duct of the car air conditioner corresponding to each car seat, For the The minimum opening limit of the car air conditioning duct corresponding to each car seat, No. The maximum opening limit of the car air conditioning air duct corresponding to each car seat.

[0082] Example: Assume that the opening limit of a car air conditioning duct is (15% - 85%), and the optimized control opening calculated at a certain seat is (90%). Since (90%) exceeds the limit range, the target opening of the car air conditioning duct corresponding to the seat is adjusted to (85%).

[0083] In addition, the opening instructions of multiple consecutive cycles can be averaged to smooth the output curve and avoid noise or vibration caused by frequent adjustments.

[0084] In an alternative embodiment, see Figure 6 As shown, Figure 6 The flowchart of the second automobile air conditioning control method provided in the first embodiment of the present invention is shown, wherein the method further includes steps S601 to S604: S601: Acquire current seat temperatures at different vehicle seats.

[0085] Specifically, each seat temperature sensor continuously works during the operation of the car air conditioner, collecting the current seat temperature of different car seats at a certain time interval. These sensors can sense the temperature around each seat in real time and accurately transmit the data to the vehicle processor.

[0086] S602: Calculate the average seat temperature of the current seat temperature at each vehicle seat, and calculate the temperature difference between the average seat temperature and the vehicle air conditioner set temperature.

[0087] Specifically, the average current seat temperature of each car seat is calculated to comprehensively reflect the overall temperature condition in the car. Then the average seat temperature is compared with the car air conditioner set temperature to calculate the temperature difference between them. The car air conditioner set temperature is the comfortable temperature that the user expects to achieve, while the average seat temperature represents the actual temperature level in the car. By calculating this difference, the gap between the current car temperature and the user's expected temperature can be known, providing a basis for subsequent control operations.

[0088] S603: Determine whether the temperature difference exceeds a preset threshold.

[0089] Specifically, the calculated temperature difference is compared with the preset threshold. If the temperature difference is small, it means that the temperature inside the car basically meets the user's setting requirements and no additional adjustment of the air conditioner is required; if the temperature difference exceeds the preset threshold, it means that the temperature inside the car is significantly different from the temperature expected by the user, and measures need to be taken to adjust the operating status of the air conditioner.

[0090] S604: If the temperature difference exceeds the preset threshold, the compressor power of the automobile air conditioner and / or the fan speed of the automobile air conditioner are adjusted.

[0091] Specifically, when it is determined that the temperature difference exceeds the preset threshold, the corresponding adjustment mechanism will be triggered. It will adjust the compressor power and / or fan speed of the car air conditioner. Increasing the compressor power will enhance the cooling or heating effect of the air conditioner, and the speed at which the temperature in the car drops or rises will be faster; reducing the compressor power will weaken the cooling or heating effect. The adjustment of the fan speed will also affect the air volume and air supply effect of the air conditioner. Increasing the fan speed will increase the air volume delivered by the air conditioner, and the temperature in the car can be adjusted more quickly; reducing the fan speed will reduce the air volume and the temperature adjustment speed will also be slower. By reasonably adjusting the compressor power and fan speed, the temperature in the car can be closer to the temperature set by the user more quickly, improving the riding comfort.

[0092] In an optional embodiment, adjusting the compressor power of the automobile air conditioner includes: The compressor power adjustment amount is determined according to the temperature difference and the preset compressor power proportional coefficient; the target compressor power is determined according to the compressor power adjustment amount, the current compressor power of the automobile air conditioner and the compressor power upper limit of the automobile air conditioner; and the compressor power of the automobile air conditioner is adjusted according to the target compressor power.

[0093] Specifically, the difference between the average temperature of the seats in the car and the set temperature of the car air conditioner is calculated. The difference reflects the degree of deviation between the current actual temperature in the car and the user's expected temperature. The temperature difference is multiplied by the preset compressor power proportional coefficient to obtain the compressor power adjustment amount. This adjustment amount reflects the magnitude of the change in the compressor power to make the temperature in the car approach the set temperature. Combining the current compressor power of the car air conditioner with the previously calculated compressor power adjustment amount, the theoretical target compressor power can be obtained. In order to ensure the safe operation of the compressor and the stability of the air conditioning system, the compressor power has an upper limit. If the initially calculated target compressor power exceeds the upper limit, the target compressor power needs to be set to the upper limit; if it does not exceed, the initial calculation result is used as the target compressor power. After determining the target compressor power, the car air conditioning control system will issue a corresponding instruction to change the operating state of the compressor by adjusting the electrical parameters such as the power supply frequency and voltage of the compressor motor so that the actual power of the compressor reaches the target compressor power.

[0094] Furthermore, the average temperature inside the car is calculated avg With the set temperature T set The difference ΔT: ΔT=T set -T avg ; If ΔT exceeds the preset threshold ΔT threshold , then the power regulation is activated and the power regulation amount ΔP is determined by the following expression: ΔP=K p ×(ΔT-ΔT threshold ) Among them, K p is the compressor power proportionality coefficient (for example: 500W / ∘C, that is, the power increases by 500W for every 1°C increase in temperature difference); ΔT-ΔT threshold Indicates the temperature difference that exceeds the threshold (e.g., when ΔT=5°C, ΔP=500×2=1000W).

[0095] Then the target compressor power P is determined according to the following expression: new : P new =min(P current +ΔP,P max ); Among them, P current is the current compressor power; P max It is the upper limit of compressor power.

[0096] The fan speed of the automobile air conditioner is adjusted, including: A fan speed adjustment amount is determined according to the temperature difference and a preset fan speed proportional coefficient; a target fan speed is determined according to the fan speed adjustment amount, the current fan speed of the automobile air conditioner and an upper limit value of the fan speed of the automobile air conditioner; and the fan speed of the automobile air conditioner is adjusted according to the target fan speed.

[0097] Specifically, the difference between the average temperature of the seats in the car and the set temperature of the car air conditioner is first calculated. The preset fan speed proportional coefficient is a pre-set parameter, which builds a connection between the temperature difference and the fan speed adjustment amount. By multiplying the temperature difference with the preset fan speed proportional coefficient, the fan speed adjustment amount can be obtained. After obtaining the fan speed adjustment amount, it is combined with the current fan speed of the car air conditioner. If the temperature needs to be increased, the fan speed adjustment amount is a positive value, which is added to the current fan speed; if the temperature needs to be lowered, the fan speed adjustment amount is a negative value, which is subtracted from the current fan speed. In order to ensure the safe operation of the fan and avoid problems such as excessive noise, the fan speed of the car air conditioner has an upper limit. If the target fan speed obtained by the preliminary calculation exceeds this upper limit, the target fan speed can only be set to the upper limit; if it does not exceed the upper limit, the result of the preliminary calculation can be used as the final target fan speed. When the target fan speed is determined, the control system of the car air conditioner will send a corresponding control signal to adjust the operating state of the fan. The control system usually changes the fan speed by changing the power supply voltage and current of the fan motor or using variable frequency control to achieve the target fan speed.

[0098] Furthermore, for the same compressor power regulation, ΔT>ΔT threshold The air conditioner is triggered to adjust. The fan speed adjustment ΔRPM is determined by the following expression: ΔRPM=K T ×(ΔT-ΔT threshold ) Among them, K T is the compressor power proportional coefficient; ΔT-ΔT threshold Indicates a temperature difference that exceeds a threshold.

[0099] Then determine the target compressor power RPM according to the following expression: new : RPM new =min(RPM current +ΔRPM,RPM max ); Among them, RPM current is the current fan speed; RPM max The upper limit of the fan speed.
