[0043] In this embodiment, the method for adjusting the environment in the automobile cabin can be applied to Figure 1 In the car system shown. Figure 1 The system includes components such as control module, air conditioning equipment, air purification equipment, communication module and interaction module.

[0044] In this embodiment, an electronic control unit ECU or other components can be used as the control module. The control module can be connected to other modules such as the air conditioner through a communication controller EVCC.

[0045] The air conditioner has an air outlet that blows hot or cold air into the passenger compartment of the vehicle, thereby increasing or decreasing the temperature within the passenger compartment. The air conditioner is equipped with a temperature sensor that measures the air temperature and thereby senses the cabin temperature. The air outlet of the air conditioner has blades with adjustable angles to adjust the angle of the hot or cold air, allowing the hot or cold air to be directed toward specific items within the vehicle cabin, such as the steering wheel or a seat, thereby heating or cooling the surface of the specific item. A temperature sensor can be installed on the surface of a specific item within the vehicle cabin, such as the steering wheel or a seat, to sense the surface temperature of the heated or cooled item. Alternatively, an infrared temperature sensor can be installed on the air conditioner, with its detection direction synchronized with the hot or cold air outlet angle, to detect the surface temperature of the heated or cooled item.

[0046] Air purification equipment performs at least one of the following functions: ventilation, filtration, adsorption, photocatalysis, drying, and humidification. These functions purify the cabin air, reducing the concentration of pollutants such as volatile organic compounds (VOCs) and improving the humidity within the cabin to a comfortable level. For example, the outdoor circulation system and blower in a car can serve as air purification equipment.

[0047] In this embodiment, the vehicle cabin environment adjustment method can be executed by the control module. When the control module executes certain steps in the vehicle cabin environment adjustment method and needs to obtain certain data, or send out processed data or control instructions, the control module can call Figure 1 The modules in , or Figure 1 Other devices not shown.

[0048] In this embodiment, refer to Figure 2 , the method for adjusting the environment in the automobile cabin includes the following steps:

[0049] S1. Obtain target temperature and target air quality parameters;

[0050] S2. Establish constraints for the first and second durations based on the target air quality parameters;

[0051] S3. Establish constraints that satisfy the second and third durations based on the target temperature;

[0052] S4 establishes the first duration, the second duration, the third duration, the first power consumption and the second power consumption constraints satisfied;

[0053] S5. Obtaining the objective function of the first power consumption and the second power consumption;

[0054] S6. Solve the objective function according to the constraints to determine the values of the first power consumption, the first duration, the second power consumption, and the second duration.

[0055] In step S1, the control module can call Figure 1 The interactive module in the , thereby obtaining the target temperature and target air quality parameters. Specifically, the touch screen can be used as Figure 1 In the interactive module, after driving the car and before exiting, the driver inputs a target temperature and target air quality parameters through the interactive module. The target temperature is the desired temperature of the cabin air and surfaces such as the steering wheel and seats upon exiting the car, specifically a comfortable temperature such as 25°C. The target air quality parameters are the desired cabin air quality parameters upon exiting the car, specifically a comfortable volatile organic compound concentration below 400 ppm and a humidity of 50%, respectively. In this embodiment, the cabin air quality parameters are described using the volatile organic compound concentration as an example. The interactive module transmits the target temperature and target air quality parameters to the control module.

[0056] In step S1, the control module can call Figure 1The communication module in the control module is used to obtain the target temperature and target air quality parameters. Specifically, a communication unit with Bluetooth, WiFi or 5G communication protocol can be used as the communication module. The communication module is connected to a mobile terminal such as a mobile phone carried by the driver through a wireless communication protocol. The driver can edit the target temperature and target air quality parameters by operating the mobile phone, and send the target temperature and target air quality parameters directly to the communication module through communication protocols such as Bluetooth or WiFi, or upload the target temperature and target air quality parameters to the cloud server through the 5G communication protocol, and then the cloud server sends the target temperature and target air quality parameters to the communication module. The communication module sends the target temperature and target air quality parameters to the control module.

[0057] Steps S2-S4 are steps for establishing constraints. In this embodiment, the constraints are explained using the cooling function of an automotive air conditioner as an example. Since heating in an automotive air conditioner is equivalent to the reverse heat transfer during the cooling process, the constraints can be established based on the same principle.

[0058] In step S2, the current volatile organic compound concentration detected by the air purification equipment is assumed to be C current , the target air quality parameter is C target , establish the constraints satisfied by the first duration t1 and the second duration t2:

[0059]

[0060] In step S3, the current cabin temperature detected by the automobile air-conditioning equipment is assumed to be T current , the target temperature is T target , then establish the constraints satisfied by the second duration t2 and the third duration t3:

[0061]

[0062] In step S4, the constraints satisfied by the first duration t1, the second duration t2, and the third duration t3 are established:

[0063] t1+t2+t3 <t 计划用车 -t 当前 (3)

[0064] t1,t2,t3≥0 (4)

[0065] Establish the first power consumption K W and the second power consumption G W The constraints that are satisfied are:

[0066] K min <K W <K max (5)

[0067] G min <G W <G max (6)

[0068] G W =f(V) (7)

[0069] In step S5, establish the first power consumption K W and the second power consumption G W The objective function is:

[0070] argmin[G W (t1+t2+t3)+K W (t2+t3)] (8)

[0071] The principles of (1)-(8) above are:

[0072] By performing external circulation ventilation through the automobile air purification equipment and cooling or heating through the automobile air conditioning equipment, the concentration of target volatile organic compounds and other pollutants in the car can be reduced, and the air temperature in the cabin can be lowered or increased. Therefore, through mathematical programming, an objective constraint function can be established to minimize the energy consumption when the target volatile organic compound concentration in the car is reduced to the target value and the air temperature becomes the target value; based on this, the automobile air purification equipment and the automobile air conditioning equipment are designed to operate in three modes: mode 1, mode 2 and mode 3, wherein mode 1 is a mode in which the automobile air conditioning equipment and the automobile air purification equipment adopt external circulation for ventilation only but not for cooling, and the working time of mode 1 is the first time length t1, mode 2 is a mode in which the automobile air conditioning equipment and the automobile air purification equipment adopt external circulation for ventilation and cooling at the same time, and the working time of mode 2 is the second time length t2, and mode 3 is a mode in which the automobile air conditioning equipment and the automobile air purification equipment adopt internal circulation for ventilation and cooling at the same time, and the working time of mode 3 is the third time length t3;

[0073] For mode 1: When external circulation is used and only ventilation is performed without cooling, within the time period dt, the air volume ΔL replaced by the car air purification equipment satisfies ΔL=L h dt, where L h is the volume of the space inside the car; after the car air purification equipment replaces the air, the internal temperature change meets The differential equation for the rate of change of volatile concentration [i.e., formula (1)] satisfies Among them C internal is the concentration of volatile organic compounds in the current cabin air detected by the air purification equipment, C external is the volatile organic compound concentration in the outside air.

[0074] For mode 2: When external circulation is used and cooling is performed during ventilation, the power of the automobile air-conditioning equipment is the first power consumption KW , let the coefficient of performance (COP) be COP, and within the time period dt, the cooling capacity ΔQ of the automobile air-conditioning equipment satisfies: ΔQ=K w ·COP·dt; On the other hand, during the time period dt, the heat of the air cooled and transported by the automobile air conditioning equipment is r air = L·cp·ρ, where cp is the specific heat capacity of air, which can be set to 1.005 kj / kg.K, and ρ is the air density, which can be set to 1.293 kg / m 3 The heat released to the air by the car seats, steering wheel, instrument panel and other equipment in the car (also cooled and transported by the car air conditioning equipment) is r other =L other ·cp other ·ρ other , where L other 、cp other and ρ other They are the average volume, average specific heat capacity and average density of these in-vehicle devices respectively; when cooling is performed simultaneously during ventilation, the internal temperature change satisfies The differential equation for temperature change [i.e., formula (2)] satisfies:

[0075]

[0076] Among them, T current is the current temperature inside the car, T external The detected outside temperature.

[0077] For mode 3: When internal circulation is used and cooling is performed during ventilation, the volatile matter concentration change rate (i.e., formula (1)) satisfies Same as Mode 2, the temperature change rate [i.e., formula (2)] satisfies:

[0078]

[0079] In equations (1)-(8), except for the first power consumption K to be determined W , the second power consumption G W , the first time length t1, the second time length t2 and the third time length t3 and other parameters, as well as the external temperature T measured by the sensor that can be called by the control module external In addition to other parameters, the average density of in-vehicle equipment ρ other Parameters such as the above can be obtained by calibrating the vehicle and can be pre-written as constants and stored in the storage component of the control module.

[0080] t in formula (3) 计划用车 represents the target usage time, t 当前represents the current moment. Formula (3) constrains that all the work of Mode 1, Mode 2 and Mode 3 must be completed before the planned use of the vehicle. Formula (4) constrains that the first duration t1, the second duration t2 and the third duration t3 are not less than 0. Formulas (5) and (6) respectively constrain the first power consumption K W and the second power consumption G W The maximum and minimum values of the second power consumption G W is a function of the ventilation speed V; formula (8), i.e., the objective function, means that the total power consumption of the automobile air-conditioning equipment and the automobile air purification equipment is minimized.

[0081] In this embodiment, the control module can use equations (1)-(7) as constraints to solve the objective function (8). Specifically, the control module can run a toolkit such as scipy.optimize to solve the problem, thereby obtaining a suitable first power consumption K W , the second power consumption G W , the numerical values of variables such as the first duration t1, the second duration t2 and the third duration t3.

[0082] The control module is based on the first power consumption K W , the second time length t2 and the third time length t3 generate a first control instruction, and send the first control instruction to the automobile air-conditioning device, so as to control the automobile air-conditioning device to not work in mode 1 from the time of receiving the first control instruction, and to use the first power consumption K W The second time period t2 is continued in mode 2, and the third time period t3 is continued in mode 3; the control module is based on the second power consumption G W , the first time length t1, the second time length t2 and the third time length t3 generate a second control instruction, and send the second control instruction to the automobile air purification equipment, so as to control the automobile air purification equipment to work continuously for the first time length t1 in mode 1, the second time length t2 in mode 2, and the third time length t3 in mode 3 at the second power consumption P2 from the time of receiving the second control instruction, thereby realizing controlling the automobile air-conditioning equipment and the automobile air purification equipment to work in advance when the driver and passengers are not on the car, so that the driver and passengers can immediately enjoy a comfortable temperature, the tactile temperature of the items in the cabin and good air quality when they return to the car, thereby improving the comfort of the cabin space. On this basis, according to the energy storage situation of the car and the time from the current time to the target usage time, appropriate working time and working power consumption control strategies can be implemented to achieve a balance between comfort, energy saving and vehicle use guarantee.

[0083] When the control module executes step S5, that is, the step of obtaining the objective function, it can specifically perform the following steps:

[0084] S501. Detecting the available energy information of the car;

[0085] S502. Set an objective function based on the target usage time and available energy information.

[0086] In step S501, the control module may call the vehicle's installed navigation module to obtain the vehicle's navigation information; call the vehicle's installed fuel level sensor (for pure fuel vehicles) to detect the current stored fuel level and obtain current energy reserve information, or call the vehicle's installed power sensor (for pure electric vehicles) to detect the current remaining power and obtain current energy reserve information. The navigation information indicates the coordinates of the road section that the vehicle will pass through in the future, as well as information such as the road shape, road conditions, and the distribution of gas stations (charging stations); the current energy reserve information indicates the amount of fuel or battery power currently stored in the vehicle.

[0087] In step S501, the control module may determine the energy consumption per unit length (specifically, fuel consumption or electricity consumption) based on information such as the road shape and road conditions indicated by the navigation information. The control module then calculates estimated energy consumption information based on the road section length indicated by the navigation information and the energy consumption per unit length. The estimated energy consumption information indicates the amount of energy (specifically, fuel consumption or electricity consumption) that the vehicle will consume to complete the road section indicated by the navigation information.

[0088] When executing step S501, the control module may directly subtract the energy consumption represented by the estimated energy consumption information from the energy represented by the current energy reserve information, thereby obtaining the available energy information.

[0089] When executing step S501, the control module can also determine the distribution location of gas stations (charging stations) along the way and the available stay time based on the navigation information, thereby determining the expected energy replenishment information, where the expected energy replenishment information indicates how much energy (specifically, the amount of oil or electricity) the car can replenish by refueling (charging) on the road section determined by the navigation information; the control module can directly subtract the energy consumption indicated by the expected energy consumption information from the energy indicated by the current energy reserve information, and add the energy indicated by the expected energy replenishment information to obtain the available energy information.

[0090] In this embodiment, the current energy reserve information, expected energy consumption information, and available energy information can be expressed using the same dimension, which can be joules, degrees (for pure electric vehicles), liters (for pure fuel vehicles), or percentages.

[0091] In this embodiment, by executing step S501 , the available energy information obtained indicates the amount of energy available for use under the conditions of the current location of the vehicle and the driving task to be performed.

[0092] In this embodiment, when executing step S502, that is, setting the objective function according to the target usage time and the available energy information, the following steps may be specifically performed:

[0093] S50201. Determine the advance start time based on the target usage time and the current time;

[0094] S50202. When the advance start duration is less than the duration threshold and the available energy information is greater than the energy threshold, the objective function is set to minimize the duration;

[0095] S50203. When the early start duration is greater than the duration threshold and the available energy information is less than the energy threshold, the objective function is set to minimize energy consumption;

[0096] S50204. When the early start duration is greater than the duration threshold and the available energy information is greater than the energy threshold, an objective function is set to minimize the sum of the first power consumption and the second power consumption;

[0097] S50205. When the early start duration is less than the duration threshold and the available energy information is less than the energy threshold, the first power consumption is set to zero and the objective function is set with the goal of minimizing the second power consumption, or the second power consumption is set to zero and the objective function is set with the goal of minimizing the first power consumption.

[0098] In step S50201, refer to Figure 3 The control module takes the target usage time as the end point and the current time as the starting point to calculate the advance start time T advance . Advance start time T advance It indicates the length of time that the car air conditioning device and the car air purification device can work before the target usage time, that is, the time when the driver wants to return to the car to use the car, if the car air conditioning device and the car air purification device are started in advance at the current time.

[0099] In steps S50202-S50205, a time threshold can be set. advance If it is less than the duration threshold, the early start duration T can be determined. advance Shorter, when starting in advance, the duration is T advance If it is greater than or equal to the duration threshold, the early start duration T can be determined. advance Longer, for example, the duration threshold can be set to 20 minutes; an energy threshold can be set. When the available energy information is less than the energy threshold, it can be judged that the available energy is insufficient. When the available energy information is greater than or equal to the energy threshold, it can be judged that the available energy is sufficient. For example, the energy threshold can be set to 50%.

[0100] When executing steps S50202-S50205, the control module determines the advance start time T advance The relationship between the duration threshold and the available energy information and the energy threshold has the following results:

[0101] (1) Advance start time T advance Less than the duration threshold, and the energy information can be used to be greater than (or equal to) the energy threshold, and the objective function is set with the duration minimization as the goal; for example, the objective function is set to argmin[max(t1, t2, t3)];

[0102] (2) When the advance start time is T advance If the duration is greater than (or equal to) the time threshold and the energy information is less than the energy threshold, the objective function is set to minimize energy consumption; for example, the objective function is set to argmin[G W (t1+t2+t3)+K W (t2+t3)], this objective function has the same form as formula (8);

[0103] (3) When the advance start time is T advance is greater than (or equal to) the duration threshold, and the energy information can be used to be greater than (or equal to) the energy threshold, and the objective function is set to minimize the sum of the first power consumption and the second power consumption; for example, the objective function is set to argmin(K W +G W );

[0104] (4) When the advance start time is T advance If the duration threshold is less than the available energy information, and the available energy information is less than the energy threshold, the first power consumption is set to zero, and the objective function is set to minimize the second power consumption, that is, argmin(G W ), or set the second power consumption to zero and set the objective function to minimize the first power consumption, that is, argmin(K W ).

[0105] In this embodiment, the objective functions obtained in the above cases (1)-(4) can replace the objective functions shown in formula (8) respectively and be used when executing steps S1-S6. The principle of executing steps S50201-S50205 is:

[0106] For case (1), the advance start time T advanceThe objective function is set as argmin[max(t1, t2, t3)], which is short and has sufficient available energy. However, the air conditioning equipment and the air purification equipment do not work for a long enough time. The first time duration t1, the second time duration t2 and the third time duration t3 are usually performed at the same time. Therefore, the maximum value among them is the time required for the air conditioning equipment and the air purification equipment to complete the cabin environment adjustment. Minimizing the maximum value is the objective function, which is conducive to compressing the working time of the air conditioning equipment and the air purification equipment, so that the air conditioning equipment and the air purification equipment can complete the cabin environment adjustment in a shorter time, and the driver can obtain a cabin environment with good temperature and air quality before returning to the car after finishing his work.

[0107] For case (2), the advance start time T advance The available energy is insufficient, so it can be judged that the car air conditioning equipment and the car air purification equipment have enough time to work, which can ensure that the car air conditioning equipment and the car air purification equipment can complete the cabin environment adjustment before the driver finishes his work and returns to the car, so as to obtain a cabin environment with good temperature and air quality. However, the available energy for the car air conditioning equipment and the car air purification equipment to work is insufficient, so the argmin[G W (t1+t2+t3)+K W (t2+t3)] as the objective function, the principle of which is to make the energy consumption K of automobile air conditioning equipment W (t2+t3) and the energy consumption G of automobile air purification equipment W The sum of (t1+t2+t3) is minimized, reducing the consumption of energy stored in the car;

[0108] For case (3), the advance start time T advance Long, but sufficient available energy, it can be judged that the car air conditioning equipment and car air purification equipment have enough time to work, which can ensure that the car air conditioning equipment and car air purification equipment can complete the cabin environment adjustment before the driver finishes his work and returns to the car, so as to obtain a cabin environment with good temperature and air quality. In addition, the car has sufficient available energy to work for the car air conditioning equipment and car air purification equipment, so as to set argmin(K W +G W ) as the objective function, the principle is to make the power consumption K of the automobile air conditioning equipment W Power consumption of automobile air purification equipment G W The sum of the total power consumption is minimized, which reduces the pressure on the vehicle power supply system (including the generator or battery), reduces the load on the vehicle air conditioning equipment and the vehicle air purification equipment, and is conducive to extending the service life of vehicle components;

[0109] For case (4), the advance start time T advance If the available energy is short, it can be judged that the car air conditioning equipment and the car air purification equipment do not have enough time to work, and the available energy of the car to support the car air conditioning equipment and the car air purification equipment is insufficient, so it may not be possible to support the car air conditioning equipment and the car air purification equipment to complete the work tasks at the same time, so argmin(K W ) or argmin(G W ) as the objective function, the principle is to make the power consumption K of the automobile air conditioning equipment W Minimum (while setting the power consumption of the car air purification equipment G W Zero) or make the power consumption of automobile air purification equipment G W Minimum (while setting the power consumption K of the car air conditioning equipment W is zero), which is conducive to concentrating the energy stored in the car to supply the car air-conditioning equipment or car air purification equipment, so that the space in the cabin can reach the target in at least one of the temperature or air quality, thereby improving the comfort of the cabin space.

When the computer program is read out and run, the method for adjusting the vehicle cabin environment in this embodiment is executed, thereby achieving the same technical effect as the method for adjusting the vehicle cabin environment in the embodiment.
