These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0031] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0032] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable in appropriate circumstances, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, the process, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, products or equipment.

[0033] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0034] In the related art, the driver usually sets a fixed value according to the ambient temperature to control the temperature inside the vehicle. However, due to the large volume of the vehicle cabin of the bus, this cooling method is limited by the number of sensors, the sensitivity of temperature control is low, and it can only adapt to a single passenger scene mode, which often leads to the temperature inside the car being too high or too low, causing physical discomfort to the passengers. In addition, due to the weight requirements of the bus, the on-board air conditioner is usually arranged at the front end of the roof, resulting in high wind pressure at the front end and low wind pressure at the rear end, which makes the cooling or heating effect at the rear end significantly worse than that at the front end. In addition, there are also deficiencies in the accuracy of temperature control. For example, in buses, even if the bus is empty during certain periods of time, the on-board air conditioner still runs at full power, resulting in energy waste.

[0035] In order to solve the above problems, the embodiment of the present application provides a vehicle air conditioning control solution, which divides the vehicle cabin into zones, installs temperature sensors, controllers and human body recognition sensors in each zone, monitors the passenger conditions and regional temperatures of each zone in real time, and controls the temperature according to the passenger conditions and regional temperatures of different zones, so as to achieve the purpose of precise temperature control, avoid physical discomfort to passengers due to excessively high or low regional temperatures, thereby better meeting the personalized needs of passengers and significantly improving the comfort of passengers. In addition, when it is determined that the regional temperature of the first zone is within the set suitable temperature range, the vehicle air conditioning of the zone is promptly controlled to work at energy-saving power, thereby effectively reducing energy consumption and vehicle operating costs.

[0036] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0037] Figure 1 A flow chart of a vehicle air conditioning control method provided by an exemplary embodiment of the present application. Figure 1 As shown, the vehicle air conditioning control method includes the following steps:

[0038] S101, monitoring whether there are passengers in each partition of the vehicle cabin, and obtaining the regional temperature of each partition.

[0039] In some embodiments, before monitoring whether there are passengers in each partition of the vehicle cabin, the method further includes: dividing the vehicle cabin into areas based on the length of the vehicle cabin, the number of seats and the seat distribution to obtain partitions.

[0040] For example, Figure 2 A schematic diagram of the partitions of a vehicle cabin provided for an exemplary embodiment of the present application. Figure 2 As shown, according to the length, number of seats and seat distribution of the vehicle cabin, the vehicle cabin is divided into 8 partitions, namely A1, A2, B1, B2, C1, C2, D1 and D2. It should be noted that Figure 2 What is shown is only an example of the present application. In actual applications, when the length, number of seats and seat distribution of the vehicle cabin are different, the corresponding number of partitions and the partitioning method are also different. For example, a 6-meter segment (5.9m~6.6m) of the vehicle cabin is divided into 4 partitions, an 8-meter segment (8.1m~8.9m) of the vehicle cabin is divided into 8 partitions, a 10-meter segment of the vehicle cabin is divided into 10 partitions, a 12-meter segment of the vehicle cabin is divided into 14 partitions, and so on. There is no limitation on the number of partitions here. Generally speaking, the larger the vehicle cabin, the more corresponding partitions.

[0041] Correspondingly, whether there are passengers in each partition is monitored by a human body recognition sensor deployed in each partition, and the regional temperature of each partition is collected by a temperature sensor deployed in each partition.

[0042] S102: for a first zone with passengers, determine whether the zone temperature of the first zone is within a set suitable temperature range.

[0043] In this step, the suitable temperature range refers to the temperature range from the suitable temperature minus the temperature tolerance to the suitable temperature plus the temperature tolerance. The temperature tolerance can be flexibly adjusted according to passenger comfort, environmental conditions, equipment performance of the vehicle air conditioner, and energy-saving considerations. For example, the suitable temperature is set to 25°C, and the corresponding suitable temperature range is (25-2)°C~(25+2)°C, that is, 23°C~27°C. Correspondingly, for the first partition with passengers, based on the regional temperature of the first partition, it is determined whether the regional temperature of the first partition is within the set suitable temperature range. Reference Figure 2 If there is a passenger in the C1 partition and the corresponding regional temperature is 28°C, it is determined that the regional temperature of the partition is not within the set suitable temperature range; if the corresponding regional temperature is 26°C, it is determined that the regional temperature of the partition is within the set suitable temperature range.

[0044] S103: If the regional temperature of the first zone is within the set suitable temperature range, control the vehicle air conditioner of the first zone to operate at energy-saving power.

[0045] Here, energy-saving power means that the vehicle air conditioner operates at a lower power to reduce energy consumption. Figure 2 , when the regional temperature of the C1 partition is within the set suitable temperature range, the controller deployed in the C1 partition controls the vehicle air conditioner in the partition to work at energy-saving power. Correspondingly, in the energy-saving power mode, the compressor frequency of the vehicle air conditioner in the partition is reduced, and the fan speed is slowed down. For example, the operating frequency of the compressor is reduced from 50Hz to 30Hz, and the fan speed is slowed down from 1500 rpm to 1000 rpm. Accordingly, when the vehicle air conditioner is in cooling mode, it can temporarily exit the excessive cooling capacity and wind speed ratio distribution; when the vehicle air conditioner is in heating mode, it can temporarily exit the excessive cooling heat and wind speed ratio distribution; thereby reducing the energy consumption of the entire vehicle while ensuring the comfort of passengers.

[0046] The vehicle air conditioning control method provided in the embodiment of the present application realizes accurate temperature control of the first partition with passengers by monitoring the passenger conditions and the regional temperature of each partition, avoiding the discomfort caused to the passengers by the regional temperature being too high or too low, thereby better meeting the personalized needs of the passengers and significantly improving the comfort of the passengers. In addition, when it is determined that the regional temperature of the first partition is within the set suitable temperature range, the vehicle air conditioning of the first partition is promptly controlled to work at energy-saving power, thereby effectively reducing energy consumption and vehicle operating costs.

[0047] In some embodiments, the vehicle air-conditioning control method also includes: if the regional temperature of the first zone is not within the set suitable temperature range, identifying the target number of passengers in the first zone; determining the target air-conditioning operating parameters corresponding to the target number of passengers based on the correspondence between the number of passengers and the air-conditioning operating parameters; controlling the vehicle air-conditioning of the first zone to operate with the target air-conditioning operating parameters, wherein the power of the vehicle air-conditioning operating with the target air-conditioning operating parameters is greater than the energy-saving power.

[0048] For example, still refer to Figure 2 , when there are passengers in the C1 partition, and the regional temperature of the C1 partition is not within the set suitable temperature range, such as 23℃~27℃, the number of passengers in the C1 partition is identified by a human body recognition sensor (such as a seat sensor or an infrared sensor, etc.). For example, if two passengers are detected in the C1 partition, the target air conditioning operating parameters corresponding to the two passengers are searched from the pre-set parameter table based on the corresponding relationship between the number of passengers and the vehicle air conditioning operating parameters of the partition. For example, the operating frequency of the compressor corresponding to one passenger is 40Hz and the fan speed is 1200 rpm; the operating frequency of the compressor corresponding to two passengers is 50Hz and the fan speed is 1500 rpm; the operating frequency of the compressor corresponding to three passengers is 60Hz and the fan speed is 1800 rpm; the operating frequency of the compressor corresponding to four passengers is 70Hz and the fan speed is 2100 rpm, and so on. Correspondingly, according to the above corresponding relationship, the target air-conditioning operating parameters are determined to be a compressor frequency of 50 Hz and a fan speed of 1500 rpm; further, the vehicle air-conditioning in the C1 partition is controlled to operate with the operating parameters of a compressor frequency of 50 Hz and a fan speed of 1500 rpm.

[0049] In the embodiment of the present application, when the regional temperature of the first zone is not within the set suitable temperature range, the number of passengers in the first zone is automatically identified, and the corresponding target air-conditioning operating parameters are adjusted based on the number of passengers, so that the regional temperature of the first zone can be adjusted more accurately to meet the comfort requirements of the passengers and to avoid energy waste caused by excessive power adjustment of the vehicle air conditioner as much as possible.

[0050] In some embodiments, the vehicle air conditioning control method further includes: for a second partition without passengers, if the regional temperature of the second partition does not meet the temperature adjustment condition, controlling the vehicle air conditioning of the second partition to operate at an energy-saving power.

[0051] For example, still refer to Figure 2 If there are no passengers in the B2 partition and the temperature of the corresponding area does not meet the preset temperature adjustment conditions (for example, the temperature is too high in summer or too low in winter), the vehicle air conditioner in the B2 partition is controlled to work at energy-saving power. Correspondingly, in the energy-saving power mode, the compressor frequency of the vehicle air conditioner in the B2 partition is reduced and the fan speed is slowed down, thereby reducing energy consumption. For example, the operating frequency of the compressor is reduced from 50Hz to 30Hz, and the fan speed is slowed down from 1500 rpm to 1000 rpm.

[0052] In the embodiment of the present application, the operating parameters of the corresponding vehicle air-conditioning are controlled based on the regional temperature and temperature adjustment conditions of the non-passenger zone, so that when there is no one in the zone, the corresponding vehicle air-conditioning runs at a lower power, thereby saving energy while still maintaining the basic temperature adjustment function, avoiding passengers from feeling that the temperature in the area is too high or too low when getting on the bus, thereby improving the comfort of the passengers after getting on the bus.

[0053] In some embodiments, the temperature adjustment conditions and the suitable temperature range are pre-set based on big data, and the big data includes at least one or any combination of weather forecasts, historical seasonal data, historical day data, and historical passenger volume data.

[0054] For example, in one implementation, the current and future weather forecast data are obtained at preset time intervals, and the obtained weather forecast data are processed and analyzed using big data analysis tools to extract the temperature at each time point. Furthermore, the temperature adjustment conditions (i.e., threshold temperature) and the suitable temperature range are set in combination with the temperature at each time point. For example, the temperature adjustment condition corresponding to 12 o'clock in summer is set to 30°C, and the suitable temperature range is 22°C to 28°C; the temperature adjustment condition corresponding to 9 o'clock in winter is set to 16°C, and the suitable temperature range is 20°C to 26°C.

[0055] In another implementation, current and future weather forecast data are obtained at preset time intervals, as well as historical seasonal data (such as seasonal temperature change data), historical daily data (such as temperature data on holidays or weekdays), and historical passenger volume data (such as passenger volume data at different time periods and on different routes), etc. Big data analysis tools are used to process and analyze the obtained data, such as the temperature change patterns in different seasons and under different weather conditions, the relationship between passenger volume and temperature control requirements, etc. Based on the analysis results, a mathematical model of temperature control conditions and suitable temperature range is established. For example, the suitable temperature range for different seasons and weather conditions can be set according to weather forecast data and historical seasonal data; the temperature adjustment conditions for different numbers of passengers can be set according to historical passenger carrying capacity data; further, the temperature adjustment conditions and suitable temperature range obtained by analysis can be pre-set in the control system of the vehicle air conditioner, for example, the temperature adjustment condition corresponding to 12 o'clock on a sunny day in summer is 30°C, and the suitable temperature range is 22°C to 28°C; the temperature adjustment condition corresponding to 9 o'clock on a cloudy day in winter is 16°C, and the suitable temperature range is 20°C to 26°C; the temperature adjustment condition corresponding to 8 o'clock on a sunny day in summer (rush hour) is 28°C, and the suitable temperature range is 19°C to 25°C.

[0056] It should be noted that the above examples are respectively explained using weather forecast data, and a combination of weather forecast, historical seasonal data, historical day data, historical passenger volume data, etc. In actual applications, any one or more combinations of weather forecast, historical seasonal data, historical day data, historical passenger volume data, etc. can be selected according to actual conditions. The specific type of big data is not limited here.

[0057] In the embodiment of the present application, the temperature adjustment conditions and the suitable temperature range are pre-set through big data, so that the vehicle air conditioner can adjust the temperature more accurately, so that passengers can feel the initial comfortable temperature as soon as they get on the vehicle, thereby improving the passenger experience under different environmental and time conditions. In addition, by dynamically acquiring current and future weather forecast data and analyzing it in combination with historical data, the temperature adjustment conditions and the suitable temperature range can be dynamically adjusted according to environmental changes, thereby providing a more flexible and efficient temperature control strategy; and through intelligent temperature adjustment, while ensuring passenger comfort, it can also avoid energy consumption caused by excessive adjustment.

[0058] It should be noted that a temperature adjustment condition and an appropriate temperature range may be set for the vehicle cabin, and different temperature adjustment conditions and appropriate temperature ranges may be set for each partition in the vehicle cabin. Figure 2For the B2 zone, since this zone is equipped with a "love double chair", considering that the passengers in this zone are usually the elderly, pregnant women or young children who need care, relatively mild temperature adjustment conditions and suitable temperature ranges can be set for this zone. For example, the temperature adjustment condition corresponding to 12 o'clock on a sunny day in summer is 28°C, and the suitable temperature range is 24°C to 26°C, thereby improving the comfort of passengers in this zone.

[0059] Based on the above embodiments, in some embodiments, the vehicle air-conditioning control method also includes: if the regional temperature of the second partition meets the temperature regulation requirements, controlling the vehicle air-conditioning of the second partition to operate at the target power, so as to adjust the regional temperature of the second partition to not meet the temperature regulation requirements, and the target power is greater than the energy-saving power.

[0060] For example, the temperature adjustment condition corresponding to 12 o'clock on a sunny day in summer is set to 30°C, and the suitable temperature range is 22°C to 28°C. Figure 2 If the regional temperature of the B2 partition is 38°C, since the regional temperature of the area is greater than 30°C, the temperature regulation requirement is met, the vehicle air conditioner of the B2 partition is controlled to work at high power, for example, the operating frequency of the compressor is 60Hz and the fan speed is 1800 rpm, so as to quickly adjust the regional temperature of the B2 partition to 30°C, so that passengers have an initial cool experience when getting on the bus.

[0061] Furthermore, when the regional temperature of the B2 partition reaches 30°C, if it is monitored that there are still no passengers in the partition, the vehicle air conditioner in the B2 partition is controlled to operate at energy-saving power. For example, the operating frequency of the compressor can be reduced from 60Hz to 30Hz, and the fan speed can be slowed down from 1800 rpm to 1000 rpm; and at the same time, whether there are passengers in the partition is monitored; if it is monitored that there are passengers in the partition, determine whether the regional temperature of the partition is within the temperature range of 22°C to 28°C; if the regional temperature of the partition is not within the temperature range of 22°C to 28°C, identify the number of passengers in the partition, and determine the target air-conditioning operating parameters corresponding to the number of passengers based on the corresponding relationship between the number of passengers and the air-conditioning operating parameters, and control the vehicle air-conditioning in the partition to operate with the target air-conditioning operating parameters; if the regional temperature of the partition is within the temperature range of 22°C to 28°C, control the vehicle air-conditioning in the partition to operate at energy-saving power.

[0062] In the embodiment of the present application, when it is detected that the temperature of the zone without passengers meets the temperature adjustment requirements, the vehicle air conditioner of the corresponding zone is controlled to operate at the target power, and the regional temperature of the corresponding zone is quickly adjusted to not meet the temperature adjustment requirements, thereby improving the comfort of passengers when getting on the bus. In addition, by monitoring the regional temperature of the zone without passengers and whether there are passengers, the working state of the vehicle air conditioner of the corresponding zone is dynamically adjusted, thereby achieving accurate temperature control of the corresponding zone.

[0063] In addition, considering that the boarding and alighting doors are opened frequently and frequently exchange temperature with the ambient temperature, the on-board air conditioners corresponding to the boarding and alighting door areas can be controlled to operate at high power to maintain the temperature of the corresponding areas at a certain temperature value (for example, 30°C in summer and 16°C in winter), thereby avoiding the temperature of these two areas being too high or too low.

[0064] Furthermore, taking into account the different temperature preferences of different passengers, for example, in summer, passengers who do not like the temperature to be too low can sit in a less crowded area or in an area close to the boarding and alighting doors; alternatively, passengers can also adjust the mechanical air outlets of the air conditioner in the seating area according to their preferences, such as adjusting the air outlet direction or air outlet volume, etc., so as to meet the passengers' personalized needs.

[0065] Figure 3 Another flow chart of the vehicle air conditioning control method provided by the exemplary embodiment of the present application. Figure 3 As shown, the vehicle air conditioning control method includes the following steps:

[0066] S301, obtaining temperature adjustment conditions, suitable temperature range and regional temperature of each partition.

[0067] The regional temperature of each zone can be collected at preset time intervals (such as 5 seconds, 30 seconds or 1 minute, etc.) through temperature sensors deployed in each zone; and the temperature adjustment conditions and suitable temperature range can be pre-set in the following implementation methods:

[0068] For example, in one implementation, the temperature adjustment condition and the suitable temperature range are both pre-set based on big data, and the big data includes at least one or any combination of weather forecast, historical season data, historical day data, and historical passenger volume data. For example, the temperature adjustment condition (i.e., threshold temperature) corresponding to 8 o'clock on a sunny summer day (peak work time) is 28°C, and the suitable temperature range is 19°C to 25°C.

[0069] In another implementation, the driver pre-sets the temperature according to factors such as ambient temperature. For example, in the hot summer, when the outdoor ambient temperature is 37°C, the driver starts the vehicle and turns on the vehicle air conditioner, and sets the temperature adjustment condition to 30°C and the suitable temperature range to 22°C~28°C.

[0070] S302, monitoring whether there are passengers in each partition of the vehicle cabin.

[0071] For example, whether there are passengers in each zone is monitored by deploying human body recognition sensors in each zone.

[0072] If yes, execute S303;

[0073] If not, execute S308.

[0074] S303: Identify the target number of passengers in the partitions where there are passengers.

[0075] For example, the number of passengers in a zone where there are passengers is identified by a human body recognition sensor (such as a seat sensor or an infrared sensor, etc.).

[0076] S304: Determine target air-conditioning operating parameters corresponding to the target number of passengers based on the corresponding relationship between the number of passengers and the air-conditioning operating parameters.

[0077] For example, in summer, based on the number of passengers, the proportional distribution of cooling capacity and wind speed is determined to match the number of passengers. For example, less cooling capacity is allocated to areas with fewer passengers, and more cooling capacity is allocated to areas with more passengers. In winter, based on the number of passengers, the proportional distribution of heating capacity and wind speed is determined to match the number of passengers. For example, less heating capacity is allocated to areas with fewer passengers, and more heating capacity is allocated to areas with more passengers.

[0078] S305 , controlling the vehicle air conditioner in the zone where the passengers are located to operate at target air conditioning operating parameters.

[0079] S306: Determine whether the area temperature of the partition where passengers are located is within a set suitable temperature range.

[0080] If yes, execute S307;

[0081] If not, execute S302.

[0082] S307, controlling the vehicle air conditioner in the partition where there are passengers to operate at energy-saving power.

[0083] Further, S306 is executed to determine whether the regional temperature of the partition with passengers is within the set suitable temperature range, and a temperature adjustment cycle for the partition with passengers is formed through S302~S307 to maintain the regional temperature of the corresponding partition within the suitable temperature range.

[0084] S308. Determine whether the regional temperature of the partition without passengers meets the temperature adjustment condition.

[0085] If yes, execute S309;

[0086] If not, execute S310.

[0087] For example, in summer, the temperature adjustment condition is set to 30°C and the suitable temperature range is 22°C~28°C. Figure 2, if the regional temperature of the C1 partition without passengers is greater than 30°C, it is determined that the C1 partition meets the temperature adjustment condition; if the regional temperature of the C1 partition without passengers is less than 30°C, it is determined that the C1 partition does not meet the temperature adjustment condition. Accordingly, in winter, the temperature adjustment condition is set to 16°C, and the suitable temperature range is 20°C to 26°C. If the regional temperature of the C1 partition without passengers is less than 16°C, it is determined that the C1 partition meets the temperature adjustment condition; if the regional temperature of the C1 partition without passengers is greater than 16°C, it is determined that the C1 partition does not meet the temperature adjustment condition.

[0088] S309: Control the vehicle air conditioner in the partition without passengers to operate at the target power.

[0089] For example, the target power is high power or other power values ​​that can achieve rapid adjustment of regional temperature. For example, in summer, if the regional temperature of the C1 partition without passengers is greater than 30°C, it is determined that the C1 partition meets the temperature adjustment conditions, and the on-board air conditioner of the C1 partition is controlled to operate at high power to quickly adjust the regional temperature of the C1 partition to 30°C, so as to avoid physical discomfort to passengers due to excessively high regional temperature of the partition after passengers get on the bus. Correspondingly, in winter, if the regional temperature of the C1 partition without passengers is less than 16°C, it is determined that the C1 partition meets the temperature adjustment conditions, and the on-board air conditioner of the C1 partition is controlled to operate at high power to quickly adjust the regional temperature of the C1 partition to 16°C, so as to avoid physical discomfort to passengers due to excessively low regional temperature of the partition after passengers get on the bus.

[0090] Further, S308 is executed to determine whether the regional temperature of the partition without passengers meets the temperature adjustment condition, and a temperature adjustment cycle for the partition without passengers is formed through S302 and S308-S310 to maintain the regional temperature of the corresponding partition at the threshold temperature.

[0091] S310, controlling the vehicle air conditioner in the partition without passengers to operate at energy-saving power.

[0092] For example, the operating frequency of the compressor is controlled to decrease from 50 Hz to 30 Hz, and the speed of the fan is slowed down from 1500 rpm to 1000 rpm.

[0093] In the embodiment of the present application, the temperature adjustment conditions and the suitable temperature range are pre-set through big data, so that passengers can feel the initial comfortable temperature as soon as they get on the bus, thereby improving the riding experience of passengers under different environments and different time conditions. In addition, by monitoring the passenger conditions and regional temperatures of each partition, dynamic monitoring and adjustment of the regional temperature of each partition is achieved. Through one cycle, the regional temperature of the partition without passengers is adjusted to the threshold temperature, and through another cycle, the regional temperature of the partition with passengers or the partition where passengers gather is further adjusted to the suitable temperature range, thereby achieving precise temperature control for each partition, which not only improves the comfort of passengers, but also effectively reduces energy consumption and vehicle operating costs.

[0094] In summary, this application has at least the following advantages:

[0095] 1. By monitoring the passenger situation and regional temperature of each zone, accurate temperature control of the first zone with passengers can be achieved to avoid discomfort to passengers due to excessively high or low regional temperatures, thereby better meeting the personalized needs of passengers and significantly improving the comfort of passengers. In addition, when it is determined that the regional temperature of the first zone is within the set suitable temperature range, the on-board air conditioner of the zone is promptly controlled to work at energy-saving power, thereby effectively reducing energy consumption and vehicle operating costs; and when it is determined that the regional temperature of the first zone is not within the set suitable temperature range, the number of passengers in the first zone is automatically identified, and the corresponding target air-conditioning operating parameters are adjusted based on the number of passengers, so that the regional temperature of the first zone can be adjusted more accurately to meet the comfort needs of passengers and also try to avoid energy waste caused by over-adjustment.

[0096] 2. Based on the regional temperature and temperature adjustment conditions of the unoccupied partition, the working parameters of the corresponding vehicle air-conditioning are controlled, so that when there is no one in the partition, the corresponding vehicle air-conditioning runs at a lower power, saving energy while still maintaining basic temperature adjustment functions, avoiding passengers feeling that the temperature in the partition is too high or too low when sitting in the partition after getting on the bus, thereby improving the comfort of passengers after getting on the bus.

[0097] 3. By presetting the temperature adjustment conditions and suitable temperature range through big data, the vehicle air conditioner can adjust the temperature more accurately, so that passengers can feel the initial comfortable temperature as soon as they get on the vehicle, thereby improving the passenger experience under different environmental and time conditions. In addition, by dynamically obtaining current and future weather forecast data and analyzing it in combination with historical data, the temperature adjustment conditions and suitable temperature range can be dynamically adjusted according to environmental changes, thereby providing a more flexible and efficient temperature control strategy; and through intelligent temperature adjustment, while ensuring passenger comfort, it can also avoid energy consumption caused by excessive adjustment.
