The interior trim is a member disposed in a cabin of an automobile, for example, a center console, a steering wheel, an instrument panel, a shift lever, a seat, a headrest, a armrest box, a door handle, a seat belt, an atmosphere lamp, etc., and n interior trim such as interior trim 1, interior trim 2 … … interior trim n are provided in fig. 1; the control module is a component with the functions of data acquisition, data processing, data output, control and the like, and can be an electronic control unit (Electronic Control Unit, ECU); the image sensor can shoot the space in the cabin in a visible light or infrared mode, the visual field of the image sensor is large enough, and a large number of internal decorations in the cabin can be included, for example, n internal decorations in the view field of the image sensor in the figure 1; the temperature sensor has a temperature detection function, referring to fig. 1, there are n temperature sensors such as a temperature sensor 1, a temperature sensor 2 … …, and a temperature sensor n, wherein the temperature sensor 1 is mounted on the interior trim 1 for detecting the temperature of the interior trim 1, the temperature sensor 2 is mounted on the interior trim 2 for detecting the temperature … … of the interior trim 2, and the temperature sensor n is mounted on the interior trim n for detecting the temperature of the interior trim n.
In this embodiment, the image sensor and the temperature sensor may be alternatively provided, that is, only the image sensor may be provided without the temperature sensor, or only the temperature sensor may be provided without the image sensor.
In this embodiment, the vehicle-mounted air conditioner may have both the cooling and heating functions, or may have only the cooling function. Since the cooling function is a typical function of the vehicle-mounted air conditioner, the present embodiment will be described with reference to cooling as an example, for a vehicle-mounted air conditioner control method for adjusting the temperature of the interior of the automobile. When the vehicle-mounted air conditioner is controlled to operate, the vehicle-mounted air conditioner is controlled to perform cooling by default, unless otherwise specified. The control of the vehicle-mounted air conditioner to heat and the like can be based on the control of the vehicle-mounted air conditioner to cool, and part of control logic can be obtained according to the opposite logic, which belongs to the range which can be understood by the person skilled in the art.
In this embodiment, referring to fig. 1, the vehicle-mounted air conditioner is provided with an air outlet, and the air outlet can adjust the air flow direction of cold air or hot air blown by a fan of the vehicle-mounted air conditioner, so that the cold air or hot air is directly blown to the target position. The target position directly blown by cold air or hot air is cooled or heated rapidly, so that the target temperature can be reached in a short time (for example, 5 s), the temperature change rate is greatly improved compared with the temperature change rate when the target position is not directly blown, and the target position can take a longer time (for example, 5 min) to reach the target temperature under the condition that the target position is not directly blown.
In this embodiment, by enlarging the airflow flux of the air outlet and the swing range of the fan blade thereof, the air supply range of the air outlet can be sufficiently large and adjustable, so that the air outlet can change the air supply direction within a sufficiently large range, for example, any one or more pieces of trim in a large number of trim on an automobile can be arbitrarily selected as an air supply target, and the air supply target is specially supplied with air. The structure of the air outlet can be improved, so that the concentration degree of air supply of the air outlet is improved, for example, the air outlet supplies air to the interior trim 1 specially, and at the moment, other interior trims such as the interior trim 2, the interior trim 3 … … and the interior trim n cannot be directly blown by air blown by the air outlet, or the air quantity blown by the air outlet is small to be negligible.
In this embodiment, referring to fig. 2, the vehicle-mounted air conditioner control method for adjusting the temperature of the automotive interior comprises the following steps:
S1, acquiring actual temperature distribution information;
s2, acquiring target temperature distribution information;
s3, determining air conditioner control information according to the actual temperature distribution information and the target temperature distribution information;
s4, controlling the vehicle-mounted air conditioner to work according to the air conditioner control information.
In this embodiment, each step in the vehicle-mounted air conditioner control method for adjusting the temperature of the automotive interior may be executed by the control module, and when the control module needs to acquire some data, the control module may call other components to read; when the control module needs to execute the step which can be executed by the physical component, the control module can send control instructions to other components so as to call the other components to execute the step.
In this embodiment, the principle of steps S1-S4 is shown in FIG. 3.
In step S1, the actual temperature distribution information obtained by the control module indicates the spatial distribution of the actual temperature of each of the at least one automotive interior in the cabin. For example, one format and content of the actual temperature distribution information is shown in table 1.
TABLE 1
Interior decoration Actual temperature Spatial coordinates
Interior decoration 1 T1 (x1,y1,z1)
Interior 2 T2 (x2,y2,z2)
Interior 3 T3 (x3,y3,z3)
…… …… ……
Interior n Tn (xn,yn,zn)
As can be seen from table 1, the space coordinate in the cabin of the interior trim 1 is (x 1,y1,z1), and the actual temperature of the interior trim 1 is detected as T 1. The actual temperature of each interior trim can be found from table 1.
In step S2, the target temperature distribution information obtained by the control module indicates a spatial distribution of the target temperatures that each of the at least one automotive interior in the desired cabin needs to reach. For example, one format and content of the target temperature distribution information is shown in table 2.
TABLE 2
As can be seen from table 2, the space coordinates of the interior trim 1 in the cabin are (x 1,y1,z1), and it is detected that the target temperature of the interior trim 1 is T '1, that is, it is desirable to reduce the temperature of the interior trim 1 to T' 1 after the on-vehicle air conditioner is turned on to cool. The target temperature for each interior trim can be found from table 2.
The target temperature distribution information in step S2 may be set by the driver according to his/her own personal preference, for example, the driver sets specific values such as T' 1、T'2……T'n one by one according to his/her own comfort range. The target temperature which corresponds to different areas, different seasons, day and night conditions and can be comfortable for a human body can be calibrated in environments such as a laboratory and stored in a storage space of the control module, the control module can call the positioning module and the timing module to detect the information of the areas, the seasons, the day and night conditions and the like of the automobile, and the specific values of the corresponding T' 1、T'2……T'n and the like are read from the storage space, so that the target temperature distribution information is set in batches.
In step S3, the control module determines air conditioner control information according to the actual temperature distribution information obtained in step S1 and the target temperature distribution information obtained in step S2. Specifically, the air conditioner control information includes information such as a target air supply amount and a position of an air supply target. And the control module executes step S4, and when the vehicle-mounted air conditioner is controlled to work according to the air conditioner control information, the air conditioner control information is sent to the vehicle-mounted air conditioner, so that the vehicle-mounted air conditioner aims at the position of the air supply target according to the target air supply quantity to supply air to the air supply target.
In this embodiment, the principle of performing steps S1 to S4 is that: the actual temperature distribution information and the target temperature distribution information respectively comprise the spatial distribution of the actual temperature and the spatial distribution of the target temperature, so that the generated air conditioner control information can comprise the spatial distribution of the specific temperature, and when the vehicle-mounted air conditioner is controlled to work according to the air conditioner control information, the air supply opening of the vehicle-mounted air conditioner can be controlled to supply air to the specific spatial position, for example, the air supply to the specific one or more inner decorations is realized, and the specific inner decorations can reach the target temperature more quickly; the method can realize the preferential air supply of specific inner decorations with larger influence on the body temperature of the driver (such as inner decorations of seats, headrest, steering wheel and the like which are contacted with the skin of the driver in a large area) so that the specific inner decorations can reach the target temperature more quickly, thereby realizing the effect of improving the body temperature of the driver in the cabin in a shorter time; because the vehicle-mounted air conditioner does not need to wait for all the internal decorations to reach the target temperature, uncomfortable time of drivers and passengers can be reduced under the condition that the vehicle-mounted air conditioner is not started in advance, driving comfort is improved, required early starting time is reduced under the condition that the vehicle-mounted air conditioner is started in advance, and therefore the effects of quick response, energy consumption reduction and the like are achieved.
In this embodiment, when step S1, that is, the step of acquiring the actual temperature distribution information, the following steps may be specifically performed:
S101A, calling at least one interior temperature sensor;
S102A, acquiring position information of each interior temperature sensor;
S103A, detecting temperature information through each interior temperature sensor;
S104A, marking temperature information detected by the interior temperature sensor according to the position information of the interior temperature sensor, and obtaining the obtained actual temperature distribution information.
Steps S101A-S104A are the first implementation of step S1.
In step S101A, referring to fig. 1, one trim temperature sensor may be mounted for each trim (for example, a trim having a large volume and being in close contact with the occupant, such as a seat, a steering wheel, or a armrest box), and position information of each trim temperature sensor may be determined by calibration. The temperature sensors of the inner decoration can be temperature sensors which are measured based on the principles of resistance temperature effect and the like, and each temperature sensor of the inner decoration is installed together with the corresponding inner decoration, namely the position information of each temperature sensor of the inner decoration can be the same as the position of the inner decoration where the temperature sensor of the inner decoration is installed. For example, referring to fig. 1, when the temperature sensor 1 is mounted together with the interior trim 1 and the spatial coordinates of the interior trim 1 are determined to be (x 1,y1,z1) by calibration or the like, referring to table 1, the position information of the temperature sensor 1 in step S102A may be the same as the spatial coordinates of the interior trim 1, that is, (x 1,y1,z1).
In step S103A, referring to fig. 1, the control module calls the temperature sensor 1, the temperature sensor 2 … …, the temperature sensor n, etc., detects the temperature information T 1 of the interior 1 and the temperature information T 2 … … of the interior 2, respectively, and marks the temperature information T n of the interior n with the position information (x1,y1,z1)、(x2,y2,z2)……(xn,yn,zn), respectively, in step S104A, thereby obtaining the actual temperature distribution information shown in table 1.
In this embodiment, the actual temperature distribution information is detected by using the trim temperature sensor by executing steps S101A-S104A, so that the accuracy and instantaneity of the actual temperature distribution information can be improved by using the characteristics of the trim temperature sensor, and one temperature sensor is generally mounted on one trim, so that each actual temperature can be associated with a specific trim in the actual temperature distribution information shown in table 1 (for example, the trim 1 is a steering wheel, and the actual temperature of the trim 1, i.e., the steering wheel, is T 1 according to table 1), thereby improving the understandability of the data, and the granularity of the actual temperature distribution information shown in table 1 can be made large, which is beneficial to reducing the required data processing amount.
In this embodiment, when step S1, that is, the step of acquiring the actual temperature distribution information, the following steps may be specifically performed:
S101B, an image sensor is called to shoot the space in the automobile cabin, and an image in the cabin is obtained;
S102B, carrying out object identification on images in the cabins, and determining at least one automobile interior trim and corresponding position information;
S103B, carrying out temperature identification on images in the cabin, and determining temperature information of each position in the images in the cabin;
S104B, marking temperature information of corresponding positions in the cabin image according to the position information of the automobile interior trim, and obtaining actual temperature distribution information.
Steps S101B-S104B are the second implementation of step S1.
In step S101B, the control module may call the image sensor to shoot the space in the car cabin in an infrared imaging manner, so as to obtain an image in the cabin. The images in the cabin include pixel values corresponding to various positions in the cabin (both positions on the interior trim and positions not belonging to the interior trim).
In step S102B, the control module may run the trained artificial intelligence model to identify items from the images in the cabin and determine at least one automotive interior and corresponding location information. For example, the artificial intelligence model identifies an area having a steering wheel profile feature from an in-cabin image to determine as an interior 1, i.e., a steering wheel, and acquires the relative position of this area in the in-cabin image, and determines positional information of the interior 1 by establishing a conversion between the coordinate system in the in-cabin image and the in-cabin space coordinate system. The position information of the interior trim may be expressed in the form of spatial coordinates (x 1,y1,z1) in table 1 or table 2.
In step S103B, in the case where the in-cabin image is obtained through infrared imaging, the control module may determine the temperatures of the respective areas in the in-cabin image by querying the correspondence between the pixel values and the temperatures, and thus determining the temperatures of the respective areas in the in-cabin image.
In step S104B, taking interior 1 as an example, the control module may obtain the temperatures of all the pixels in the region corresponding to the interior 1 in the cabin interior image, calculate an average value, use the average value as the actual temperature T 1 of the interior 1, and mark the actual temperature with the spatial coordinates (x 1,y1,z1) of the interior 1. A similar operation was performed for all the interior trims, thereby obtaining actual temperature distribution information shown in table 1.
In this embodiment, by performing steps S101B-S104B to detect and obtain the actual temperature distribution information by means of image capturing and recognition, the characteristic that the image capturing and recognition process is fast can be utilized, and the number of pixels in the cabin image is large, and is generally far greater than the number of interior trim temperature sensors, so that the actual temperature distribution information in which each position in the cabin tends to be continuously distributed can be obtained, and in this case, in the obtained actual temperature distribution information shown in table 1, the interior trim 2 … …, etc. may not strictly correspond to a specific interior trim, but to a certain area space in the cabin (for example, the interior trim 1 in table 1 may not correspond to the whole steering wheel, but to the upper half of the steering wheel, but the interior trim 2 corresponds to the lower half of the steering wheel, and the interior trim 1 and the interior trim 2 only correspond to a complete piece of interior trim, i.e. the steering wheel), and in this case, the number of n in table 1 may be very large (for example, up to a level of 10 6), so that the obtained actual temperature distribution information shown in table 1 tends to be continuously distributed.
In this embodiment, when step S3 is performed, that is, the step of determining the air conditioner control information according to the actual temperature distribution information and the target temperature distribution information, the following steps may be specifically performed:
S301, determining temperature difference distribution information according to actual temperature distribution information and target temperature distribution information;
S302, determining air conditioner control information according to the temperature difference distribution information.
In step S301, for each of the internal decorations, a corresponding temperature difference of the internal decoration is determined according to the actual temperature and the target temperature of the internal decoration.
For example, according to table 1, the actual temperature of the interior trim 1 is T 1, and according to table 2, the target temperature of the interior trim 1 is T ' 1, and since the actual temperature T 1 is generally higher than the target temperature T ' 1 in the cooling demand, the difference Δt 1, i.e., Δt 1=T1-T'1 obtained by subtracting the target temperature T ' 1 from the actual temperature T 1 can be calculated as the temperature difference Δt 1 corresponding to the interior trim 1, and the position information corresponding to the temperature difference Δt 1 is still the spatial coordinate corresponding to the interior trim 1 (x 1,y1,z1).
Similar operations are performed for all the interior trims, and temperature distribution information as shown in table 3 can be obtained.

Interior n |ΔTn| (xn,yn,zn)
In step S302, the control module may generate air conditioner control information according to the temperature distribution information shown in table 3.
In this embodiment, when performing step S302, that is, determining the air conditioner control information according to the temperature distribution information, the following steps may be specifically performed:
S30201, setting a temperature difference threshold;
S30202, screening temperature difference information at each position in the temperature difference distribution information according to a temperature difference threshold value, and determining at least one maximum temperature difference information;
s30203, carrying out path planning according to the position information corresponding to each maximum value information of the temperature differences to obtain air supply path information;
s30204, setting a target air supply quantity;
s30205, generating air conditioner control information according to the air supply path information and the target air supply quantity.
In step S30201, the control module may set a temperature difference Threshold T, and the temperature difference Threshold T may be a constant value for determining a temperature difference information. For example, if one of the temperature difference information obtained in step S301 is greater than or equal to the temperature difference Threshold T, it may be determined that the temperature difference information is relatively large, whereas if the temperature difference information is less than the temperature difference Threshold T, it may be determined that the temperature difference information is relatively small.
In step S30202, the control module compares the temperature difference information |Δt 1|、|ΔT2|……|ΔTn | in table 3 with the temperature difference Threshold value Threshold T one by one, and screens out the temperature difference information greater than or equal to the temperature difference Threshold value Threshold T, that is, the temperature difference information belonging to the larger temperature difference, and marks the temperature difference information as the temperature difference maximum value information.
For example, assuming that when step S30202 is performed, temperature difference information |Δt 1|、|ΔT3|、|ΔT102 | is detected to be greater than or equal to the temperature difference Threshold T, the temperature difference information |Δt 1|、|ΔT3|、|ΔT102 | may be marked as temperature difference maximum value information.
In step S30203, the control module performs path planning according to the temperature difference maximum value information |Δt 1|、|ΔT3 | and |Δt 102 | and the like, and obtains air supply path information.
Specifically, referring to table 1, table 2 or table 3, the temperature difference maximum value information |Δt 1|、|ΔT3 | and |Δt 102 | correspond to the interior trim 1, the interior trim 3 and the interior trim 102, respectively, and correspond to the spatial coordinates (x 1,y1,z1)、(x3,y3,z3) and (x 102,y102,z102), respectively, and the control module may perform path planning according to the spatial coordinates (x 1,y1,z1)、(x3,y3,z3) and (x 102,y102,z102).
For example, the path planning may be targeted to generate a closed path that passes through all the location information corresponding to the maximum temperature difference information [ e.g., spatial coordinates (x 1,y1,z1)、(x3,y3,z3) and (x 102,y102,z102) ], and that has the shortest length. The position information corresponding to each maximum temperature difference information may be weighted accordingly, for example, the position information corresponding to all maximum temperature difference information may be weighted equally (for example, 1), the position information corresponding to each maximum temperature difference information may be weighted accordingly [ for example, the space coordinate (x 1,y1,z1) may be weighted accordingly to |Δt 1 |, the space coordinate (x 3,y3,z3) may be weighted accordingly to |Δt 3 |, the space coordinate (x 102,y102,z102) may be weighted accordingly to |Δt 102 | ], and the path planning algorithm may be executed on the position information corresponding to each maximum temperature difference information after the weight is weighted according to the target of the path planning, thereby generating the corresponding closed path as the air supply path information.
In this embodiment, when the generated closed path, i.e., the air supply path information path is (x1,y1,z1)→(x102,y102,z102)→(x3,y3,z3),, i.e., the path moves according to the air supply path information path, the loop may start from the space coordinate (x 1,y1,z1), jump to the space coordinate (x 102,y102,z102), jump to the space coordinate (x 3,y3,z3), and return to the space coordinate (x 1,y1,z1).
In step S30204, the control module may set the target air intake according to parameters such as performance of the vehicle-mounted air conditioner.
In step S30205, the control module packages the air supply path information path and the target air supply volume to generate air conditioning control information.
In this embodiment, the principle of performing steps S30201 to S30205 is that: by using the temperature difference threshold value to screen out the maximum value information of the temperature difference, the position information with the farthest actual temperature and the farthest target temperature can be found, namely, the position information corresponding to each maximum value information of the temperature difference, the air supply path information obtained by path planning the position information represents a path meeting the condition (such as the position information with the largest temperature difference and the shortest total path length), the air supply path information is packaged to generate air conditioner control information, when the control module executes the step S4 and controls the vehicle-mounted air conditioner by using the air conditioner control information, the vehicle-mounted air conditioner controls the air outlet of the vehicle-mounted air conditioner, and the air supply targets [ e.g. the interior 1 corresponding to the space coordinate (x 1,y1,z1), the interior 102 corresponding to the space coordinate (x 102,y102,z102) and the interior 3 corresponding to the space coordinate (x 3,y3,z3) are circularly supplied according to the air supply quantity of the target according to the air supply targets and the air supply targets determined by the air supply targets and the sequence [ e.g. (x1,y1,z1)→(x102,y102,z102)→(x3,y3,z3)],; because the maximum value information of the temperature difference corresponding to each air supply target determined by the air supply path information is the air supply target with the most urgent air supply requirement, executing the steps S30201-S30205 can realize the control of the vehicle-mounted air conditioner to supply air to the air supply target with the most urgent air supply requirement preferentially, so that the interior decorations can reach the target temperature more quickly, and the speed of improving the body temperature of drivers and passengers is increased; and because the air supply path information meets certain conditions (such as the shortest total length), the air supply range of the air outlet of the vehicle-mounted air conditioner can be limited to a smaller range, and particularly, the swing range of the fan blade in the air outlet of the vehicle-mounted air conditioner can be reduced, so that the working loss of the vehicle-mounted air conditioner is reduced, and the maintenance cost is reduced.
In this embodiment, when step S301 is performed, that is, the step of determining temperature difference distribution information according to actual temperature distribution information and target temperature distribution information, the following steps may be specifically performed:
S30101, subtracting the temperature information corresponding to the same position from the actual temperature distribution information and the target temperature distribution information to obtain temperature difference information of each position;
S30102, determining a temperature difference field according to temperature difference information of each position;
S30103, acquiring the gradient of each position of the temperature difference field;
S30104, when the gradient sizes are smaller than gradient threshold values, taking the temperature difference field as temperature difference distribution information;
s30105, blurring the temperature difference field when the magnitude of any gradient is greater than or equal to a gradient threshold value;
s30106, using the temperature difference field after blurring as temperature difference distribution information.
In step S30101, the obtained temperature difference information is |Δt 1|、|ΔT2|……|ΔTn | or the like in table 3.
In step S30102, referring to table 3, each temperature difference information corresponds to a corresponding one of the spatial coordinates, so the data shown in table 3 can be regarded as one temperature difference field.
In step S30103, the temperature difference field shown in table 3 may be interpolated to obtain gradient magnitudes at each position after being changed to a continuous field, or a discrete gradient algorithm may be used to calculate gradient magnitudes at each position.
In steps S30104 and S30105, a gradient Threshold Gradient may be set, and the gradient Threshold Gradient may be a constant value, so as to determine whether a gradient is larger or smaller. For example, if one gradient magnitude obtained in step S30103 is greater than or equal to the gradient Threshold Gradient, it may be determined that the gradient magnitude is relatively large, whereas if the gradient magnitude is less than the gradient Threshold Gradient, it may be determined that the gradient magnitude is relatively small.
If all the gradient magnitudes obtained in step S30103 are smaller than the gradient Threshold Gradient, i.e., if it is determined that all the gradient magnitudes of the temperature difference field shown in table 3 are smaller, step S30104 is performed, directly using the temperature difference field itself shown in table 3 as temperature difference distribution information used when performing step S302 to generate the air conditioner control information.
If any one of the gradient magnitudes obtained in step S30104 is greater than or equal to the gradient Threshold Gradient, that is, if it is determined that there are some positions in the temperature difference field shown in table 3 where the gradient magnitudes are relatively large, step S30105 is performed to blur the temperature difference field shown in table 3, and the temperature difference field after the blurring is used as temperature difference distribution information used when the air conditioner control information is generated in step S302.
In step S30105, table 3 may be regarded as one image (the data in tables 1 and 2 may be stored and processed in the form of an image as well), specifically, the spatial coordinates in table 3 represent pixel coordinates of the image, and the temperature difference in table 3 represents the pixel value of the pixel, so that the image may be subjected to blurring processing using an algorithm such as gaussian blurring, and the blurred temperature difference field is obtained as temperature difference distribution information.
In this embodiment, the principle of performing steps S30101-S30105 is that: the gradient sizes of all positions of the temperature difference field represent the smoothness of the distribution of the temperature difference field, and when the gradient sizes are smaller than the gradient threshold value, the temperature difference field is smooth enough and can be used as temperature difference distribution information; when the magnitude of any gradient is larger than or equal to the gradient threshold value, the temperature difference field is not smooth enough, blurring is carried out on the temperature difference field, so that the temperature difference field is smoother, and the blurred temperature difference field can be used as temperature difference distribution information; the steps S30101-S30105 are executed, the obtained temperature difference distribution information is obtained based on a temperature field, and the distribution of the temperature difference is smooth enough, so that when the step S302 is executed later, the temperature difference maximum information is determined with finer force, and the air supply path information is obtained through planning, the control module is favorable for controlling the vehicle-mounted air conditioner to carry out finer air supply control on the space in the cabin, the temperature distribution of the cabin is further improved, and the finer individuation requirement is met.
In addition, under the condition that the actual temperature distribution information is detected by using the interior trim temperature sensor in the execution of the steps S101A-S104A, the temperature sensor is arranged on the interior trim, so that the direction and the air output of the air outlet of the vehicle-mounted air conditioner can be intelligently adjusted when the temperature of the interior trim reaches the specified temperature, and the surface temperature of the interior trim is kept at a comfortable temperature all the time.
In this embodiment, when executing step S4, that is, the step of controlling the vehicle-mounted air conditioner to work according to the air conditioner control information, the following steps may be specifically executed:
S401, acquiring an air conditioner reservation starting control instruction;
S402, determining the using time of the air conditioner according to the air conditioner reserved starting control instruction;
s403, determining the early opening time according to the air supply path information;
S404, determining the starting time of the air conditioner according to the using time and the early starting time of the air conditioner;
s405, controlling the vehicle-mounted air conditioner to refrigerate or heat according to the target air supply quantity at the starting moment of the air conditioner, and supplying air according to the air supply path information.
In step S401, the driver and the passenger can set the vehicle through the human-computer interaction module. The air conditioner reservation starting control instruction indicates that a driver wants to start the vehicle-mounted air conditioner in advance, and the air conditioner reservation starting control instruction comprises air conditioner use time t 2 and air conditioner use time t 2 indicates the time when the driver estimates that the vehicle-mounted air conditioner enters the cabin of the automobile.
In step S402, the control module extracts the air conditioner use time t 2 from the air conditioner reservation start control instruction.
In step S403, the control module may determine the early turn-on duration Δt according to the length of the air supply path information path. Specifically, generally, the swing speed of the fan blade of the air outlet is fixed, so the early opening duration Δt can be set as a direct proportional function of the length of the air supply path information path. For example, according to the length of the air supply path information path and the swing speed of the fan blade, the time required for the air port to complete the circulation of the air supply path information path once can be determined, and then the preset required circulation times are multiplied to obtain the early opening duration deltat.
In step S404, an air conditioner start time t 1 is determined according to the air conditioner use time t 2 and the early-start time Δt. Specifically, the air conditioner start time t 1 may be calculated according to the formula t 1=t2 - Δt.
In step S405, the control module controls the vehicle-mounted air conditioner at the air conditioner start time t 1, performs cooling or heating according to the target air supply amount, and performs air supply according to the order of the air supply targets determined in the air supply path information path.
In this embodiment, the principle of performing steps S401 to S405 is that: the air conditioner can be started in advance to refrigerate or heat the cabin space, so that when the air conditioner is used at the time t 2, namely when a driver enters the cabin, the temperature of the interior trim in the cabin reaches the proper target temperature distribution, and the driving experience is improved; and the time for starting the air conditioner in advance, namely the time delta t for starting the air conditioner in advance, just enables the vehicle-mounted air conditioner to supply air preferentially meeting the frequency requirement to the key interior decoration, thereby reducing the unnecessary time for starting the vehicle-mounted air conditioner in advance, reducing the unnecessary work of the vehicle-mounted air conditioner and being beneficial to reducing the energy consumption.
