Therefore, this method can both reduce the energy consumption of the vehicle and keep the temperature inside the vehicle at a suitable temperature.

[0056] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application are described in further detail below.

[0057] The terms "first", "second", "third" and "fourth" etc. in the specification and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0058] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all 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 of relevant countries and regions. For example, the key signal, rainfall signal, temperature, etc. involved in this application are all obtained with full authorization.

[0059] Figure 1 is a schematic diagram of a vehicle air conditioning control system provided by an embodiment of the present application, see Figure 1 The system includes: a vehicle controller 101 (VCU, Vehicle Control Unit), a body controller 102 (BCM, Body Control Module), an air conditioning system 103 (ECC, Electronic Climate Control), a T-BOX 104 (Internet of Vehicles system), an in-vehicle temperature sensor 105 and an out-of-vehicle temperature sensor 106. The out-of-vehicle temperature sensor 106, the in-vehicle temperature sensor 105, the body controller 102, the air conditioning system 103, and the T-BOX 104 are all electrically connected to the vehicle controller 101.

[0060] The electrical connection may be a cable connection or a wireless connection, which is not specifically limited in the embodiments of the present application. If the electrical connection is a cable connection, the body controller 102 and the vehicle controller 101 may be connected via a CAN (Controller Area Network) signal line, and the air conditioning system 103 and the vehicle controller 101 may be connected via a CAN signal line. If the electrical connection is a wireless connection, the connection method may be a wireless local area network or a WiFi (Wireless Fidelity) network connection.

[0061] In an embodiment of the present application, the user can set the usage time of the vehicle and the set temperature of the air-conditioning system 103 through the terminal, and send the usage time and set temperature to the vehicle controller 101 through the T-BOX 104. Alternatively, the vehicle controller 101 can also determine the usage time and set temperature through self-learning. After receiving the usage time and set temperature, the vehicle controller 101 sends a first temperature acquisition instruction and a second temperature acquisition instruction to the outdoor temperature sensor 106 and the indoor temperature sensor 105 respectively. The outdoor temperature sensor 106 obtains the temperature outside the vehicle, that is, the first temperature, based on the first temperature acquisition instruction, and sends the first temperature to the vehicle controller 101. The indoor temperature sensor 105 obtains the temperature inside the vehicle, that is, the second temperature, based on the second temperature acquisition instruction, and sends the second temperature to the vehicle controller 101.

[0062] The number of the vehicle exterior temperature sensors 106 may be one or more, and the number of the vehicle interior temperature sensors 105 may be one or more, and there is no specific limitation on this. For example, if there are multiple vehicle interior temperature sensors 105, then the multiple vehicle interior temperature sensors 105 send the detected vehicle interior temperatures to the vehicle controller 101, and the vehicle controller 101 determines the average value of the multiple vehicle interior temperatures and determines the average value as the second temperature.

[0063] After the vehicle controller 101 obtains the first temperature and the second temperature, it determines the size relationship between the first temperature and the first preset temperature, the second preset temperature and the third preset temperature, and performs corresponding operations according to the size relationship. In addition to turning on the air-conditioning system 103, the operation also includes: turning on the external circulation fan and controlling at least one of the multiple windows of the vehicle to be lowered. Among them, when the vehicle controller 101 controls the window to be lowered, it can send a window lowering instruction to the body controller 102, and the body controller 102 controls the window to be lowered based on the window lowering instruction. The specific implementation process will be described in detail in the method embodiment, and will not be repeated here.

[0064] One thing that needs to be explained is that the vehicle air conditioner is composed of a compressor, a condenser, a large fan, a blower, etc. For the entire system, the power of the compressor and the condenser is relatively large, and the energy consumption of the vehicle also accounts for a large proportion, thus affecting the vehicle's endurance. However, this application takes into account all kinds of weather conditions and user usage scenarios through the interaction between the vehicle controller 101, the body controller 102, the air conditioning system 103 and the T-BOX 104, ensuring that the temperature inside the car is at a suitable temperature when the user needs to use the car, and at the same time, the air conditioning system 103 such as the compressor and the condenser does not work at high load, thereby reducing the vehicle's energy consumption and keeping the temperature inside the car at a suitable temperature.

[0065] Figure 2is a flow chart of a vehicle air conditioning control method provided in an embodiment of the present application, which is executed by a vehicle controller, see Figure 2 , the method comprising:

[0066] Step 201: The vehicle controller obtains a first temperature and a second temperature.

[0067] The first temperature is a temperature outside the vehicle, and the second temperature is a temperature inside the vehicle.

[0068] The vehicle controller can obtain the first temperature sent by the external temperature sensor and the second temperature sent by the internal temperature sensor.

[0069] In an embodiment of the present application, the vehicle controller may first obtain the usage time of the vehicle and the set temperature of the air-conditioning system, and obtain the first temperature and the second temperature when the time interval between the current time and the usage time reaches a preset time interval.

[0070] The vehicle usage time and the set temperature of the air conditioning system are set by the user through the target application on the terminal. The process may be: in response to logging into the target application, the terminal displays a remote control interface, and the remote control interface includes a usage time setting option and an air conditioning temperature setting option. In response to detecting a triggering operation on the usage time setting option and the air conditioning temperature setting option, the terminal obtains the set usage time and the set temperature of the air conditioning system. The terminal sends the usage time and the set temperature to the vehicle controller through the T-BOX, and accordingly, the vehicle controller obtains the usage time and the set temperature.

[0071] The vehicle usage time and the set temperature of the air-conditioning system can also be determined by the vehicle controller through self-learning based on the user's driving habits.

[0072] The preset time interval can be set and changed as needed, and is not specifically limited thereto. For example, the preset time interval is 10 minutes, 20 minutes, or 30 minutes.

[0073] After obtaining the first temperature, the vehicle controller determines the magnitude relationship between the first temperature and the first preset temperature, the second preset temperature, and the third preset temperature. The second preset temperature is greater than the first preset temperature, and the first preset temperature is greater than the third preset temperature. When the first temperature is greater than the first preset temperature, the vehicle controller executes step 202.

[0074] The first preset temperature, the second preset temperature and the third preset temperature can be set and changed as needed, and are not specifically limited thereto. For example, the second preset temperature is 30°C, the first preset temperature is 20°C, and the third preset temperature is 15°C.

[0075] Step 202: When the first temperature is greater than the first preset temperature, the vehicle controller determines the rotation speed of the external circulation fan of the vehicle based on a first temperature difference between the first temperature and the second temperature.

[0076] When the first temperature is greater than the first preset temperature, the vehicle controller determines a first temperature difference between the first temperature and the second temperature, and determines the rotation speed of the external circulation fan based on the first temperature difference.

[0077] Wherein, when the first temperature difference is less than the first preset difference, the vehicle controller determines that the speed of the external circulation fan is the first speed; when the first temperature difference is greater than the first preset difference and less than the second preset difference, the speed of the external circulation fan is determined to be the second speed; when the first temperature difference is greater than the second preset difference, the speed of the external circulation fan is determined to be the third speed. The second preset difference is greater than the first preset difference, the third speed is greater than the second speed, and the second speed is greater than the first speed.

[0078] The first preset difference and the second preset difference can be set and changed as needed, and are not specifically limited thereto. For example, the first preset difference is 5°C, and the second preset difference is 10°C.

[0079] In the embodiment of the present application, the first speed may be the speed corresponding to the first gear, the second speed may be the speed corresponding to the second gear, and the third speed may be the speed corresponding to the third gear. The greater the speed, the greater the gear.

[0080] After the vehicle controller determines the speed of the external circulation fan, it can adjust the external circulation fan to a corresponding gear according to the speed, and control the external circulation fan to run at a speed corresponding to the gear.

[0081] One thing that needs to be explained is that when the first temperature is greater than the first preset temperature, the vehicle controller can also obtain a rainfall signal detected by the rain sensor. When the rainfall signal indicates that there is no rainfall, when a key signal is detected, the vehicle's multiple windows are controlled to be lowered to the lowest position.

[0082] Among them, when the rainfall signal indicates that there is no rainfall, since the user is not in the car, if the vehicle controller directly controls the vehicle's multiple windows to the lowest position, the items may be lost. When the vehicle controller detects the key signal, it means that the user is approaching the vehicle. At this time, the vehicle controller controls the vehicle's multiple windows to the lowest position, which can not only avoid the loss of items, but also reduce the temperature inside the car, thereby reducing energy consumption.

[0083] The vehicle controller can control multiple windows to be lowered to the lowest position through the body controller. The process can be: the vehicle controller sends a window lowering instruction to the body controller, the window lowering instruction can carry multiple window identifiers, and the body controller controls the windows corresponding to the multiple window identifiers to be lowered to the lowest position based on the multiple window identifiers.

[0084] The number of the plurality of windows can be set and changed as required, and is not specifically limited thereto. For example, the number of the plurality of windows is 2, 3 or 4.

[0085] When the rainfall signal indicates rainfall, in order to prevent rainwater from entering the vehicle and damaging the components inside the vehicle, the vehicle controller can only control the external circulation fan to operate based on the corresponding speed.

[0086] Step 203: When the duration of the external circulation fan running at the rotation speed reaches a first preset duration, the vehicle controller obtains the current temperature inside the vehicle.

[0087] When the duration of the external circulation fan running at the speed reaches a first preset duration, the vehicle controller obtains the current temperature inside the vehicle through the in-vehicle temperature sensor to determine whether the current temperature is greater than the first temperature.

[0088] The first preset duration can be set and changed as needed, and is not specifically limited thereto. For example, the preset time interval is 20 minutes, and the first preset duration is 15 minutes, 16 minutes, or 18 minutes.

[0089] Step 204: When the current temperature is greater than the first temperature, the vehicle controller adjusts the speed of the external circulation fan.

[0090] In a possible implementation, when the current temperature is greater than the first temperature, the vehicle controller directly adjusts the rotation speed of the external circulation fan.

[0091] In this implementation, if the speed of the external circulation fan in step 202 is the first speed or the second speed, then when the current temperature is greater than the first temperature, the vehicle controller adjusts the speed of the external circulation fan to the third speed;

[0092] In another possible implementation, when the current temperature is greater than the first temperature, the vehicle controller determines a second temperature difference between the current temperature and the first temperature, and adjusts the rotation speed of the external circulation fan based on the second temperature difference.

[0093] In this implementation, in step 202, when the speed of the external circulation fan is the first speed and the second temperature difference is less than the third preset difference, the vehicle controller adjusts the speed of the external circulation fan to the second speed; in step 202, when the speed of the external circulation fan is the first speed and the second temperature difference is greater than the third preset difference, the vehicle controller adjusts the speed of the external circulation fan to the third speed. In step 202, when the speed of the external circulation fan is the second speed and the second temperature difference is less than the third preset difference, the vehicle controller adjusts the speed of the external circulation fan to the third speed.

[0094] It should be noted that, when the rotation speed of the external circulation fan is the third rotation speed in step 202, even if the current temperature is greater than the first temperature, the vehicle controller still maintains the rotation speed unchanged.

[0095] After the vehicle controller adjusts the speed of the external circulation fan, the gear of the external circulation fan can be adjusted according to the adjusted speed, and the external circulation fan can be controlled to operate at a speed corresponding to the adjusted gear.

[0096] Step 205: When the duration of the external circulation fan running at the adjusted speed reaches a second preset duration, the vehicle controller controls the air conditioning system to turn on.

[0097] This step can be achieved in any of the following ways.

[0098] In a first implementation mode, when the duration for which the external circulation fan runs at an adjusted speed reaches a second preset duration, the vehicle controller directly controls the air conditioning system to turn on.

[0099] The second implementation method is that when the external circulation fan runs at an adjusted speed for a second preset time, the vehicle controller obtains the set temperature of the air-conditioning system; determines the working mode and wind speed of the air-conditioning system based on a third temperature difference between the current temperature and the set temperature; and controls the air-conditioning system to turn on based on the working mode and wind speed of the air-conditioning system.

[0100] In this implementation, since the first temperature is greater than the first preset temperature, the vehicle controller determines that the operating mode of the air-conditioning system is the cooling mode.

[0101] The process of the vehicle controller determining the wind speed of the air conditioning system based on the third temperature difference may be: when the third temperature difference is less than the fourth preset difference, the vehicle controller determines the wind speed of the air conditioning system to be the first wind speed; when the third temperature difference is greater than the fourth preset difference and less than the fifth preset difference, the wind speed of the air conditioning system is determined to be the second wind speed; when the third temperature difference is greater than the fifth preset difference, the wind speed of the air conditioning system is determined to be the third wind speed. The fifth preset difference is greater than the fourth preset difference, the third wind speed is greater than the second wind speed, and the second wind speed is greater than the first wind speed.

[0102] It should be noted that, since the vehicle controller has obtained the set temperature of the air-conditioning system in step 201, there is no need to obtain it again here.

[0103] In the embodiment of the present application, after the external circulation fan has been running for a period of time, the temperature inside the vehicle will drop to a certain extent. At this time, turning on the air conditioning system can greatly reduce energy consumption. In addition, when turning on the air conditioning system, the wind speed of the air conditioning system is first determined based on the temperature difference between the current temperature inside the vehicle and the set temperature, and the air conditioning system is turned on based on the wind speed. In this way, when the air conditioning system is running, it does not need to work at a high load, which can further reduce energy consumption.

[0104] The third implementation method is that when the external circulation fan runs at an adjusted speed for a second preset time, the vehicle controller determines the vehicle type of the vehicle; when the vehicle type is a hybrid vehicle, the operating mode of the air-conditioning system and the driving mode of the vehicle are determined; based on the operating mode and the driving mode, the air-conditioning system is controlled to turn on.

[0105] In this implementation, the vehicle controller determines whether the vehicle type is a hybrid vehicle or a pure electric vehicle; if the vehicle type is a hybrid vehicle, the vehicle controller determines the driving mode of the hybrid vehicle. Since the first temperature is greater than the first preset temperature, the vehicle controller determines that the operating mode of the air conditioning system is the cooling mode.

[0106] Based on the working mode and driving mode, the vehicle controller can control the air conditioning system to start in the following way:

[0107] When the working mode is cooling mode and the driving mode of the hybrid vehicle is pure electric driving mode, the vehicle controller controls the air conditioning system to turn on and controls the power battery to provide power for the air conditioning system;

[0108] When the working mode is cooling mode and the driving mode of the hybrid vehicle is pure engine driving mode, the vehicle controller controls the air conditioning system to turn on, and controls the engine to drive the generator to provide power for the air conditioning system;

[0109] When the working mode is the cooling mode and the driving mode of the hybrid vehicle is the hybrid driving mode, the vehicle controller controls the air conditioning system to turn on based on the vehicle's required power.

[0110] Among them, when the working mode is cooling mode and the driving mode of the hybrid vehicle is hybrid driving mode, the vehicle controller determines whether the engine is required to perform power compensation based on the vehicle's required power. If the engine is required to perform power compensation, the vehicle controller controls the air conditioning system to turn on and controls the generator to provide power for the air conditioning system. If the engine is not required to perform power compensation, the vehicle controller controls the air conditioning system to turn on and controls the power battery to provide power for the air conditioning system.

[0111] In the embodiment of the present application, after the external circulation fan has been running for a period of time, the temperature inside the vehicle will drop to a certain extent. At this time, turning on the air conditioning system can greatly reduce energy consumption. In addition, when the air conditioning system is turned on, different power sources can be controlled to provide power for the air conditioning system according to the vehicle type and its driving mode, which can further reduce energy consumption.

[0112] A fourth implementation method is that when the duration for which the external circulation fan runs at an adjusted speed reaches a second preset duration, the vehicle controller determines the vehicle type of the vehicle; when the vehicle type is a hybrid vehicle, the operating mode of the air-conditioning system and the driving mode of the vehicle are determined; and based on the third temperature difference, the wind speed of the air-conditioning system is determined; and based on the operating mode, driving mode and wind speed, the air-conditioning system is controlled to turn on.

[0113] In this implementation, the process of the vehicle controller determining the working mode and the driving mode is the same as that of the third implementation, and the process of determining the wind speed of the air-conditioning system is the same as that of the second implementation, which will not be repeated here.

[0114] The vehicle controller controls the air conditioning system to start based on the working mode, driving mode and wind speed. The process may be as follows: when the working mode is the cooling mode and the driving mode of the hybrid vehicle is the pure electric driving mode, the vehicle controller controls the air conditioning system to start based on the wind speed of the air conditioning system, and controls the power battery to provide power for the air conditioning system.

[0115] When the working mode is cooling mode and the driving mode of the hybrid vehicle is pure engine driving mode, the vehicle controller controls the air conditioning system to turn on based on the wind speed of the air conditioning system, and controls the engine to drive the generator to provide power for the air conditioning system;

[0116] When the working mode is the cooling mode and the driving mode of the hybrid vehicle is the hybrid driving mode, the vehicle controller controls the air-conditioning system to turn on based on the wind speed of the air-conditioning system and the required power of the vehicle.

[0117] Among them, when the working mode is cooling mode and the driving mode of the hybrid vehicle is hybrid driving mode, the vehicle controller determines whether the engine is required to perform power compensation based on the vehicle's required power. If the engine is required to perform power compensation, the vehicle controller controls the air conditioning system to start based on the wind speed of the air conditioning system, and controls the generator to provide power for the air conditioning system. If the engine is not required to perform power compensation, the vehicle controller controls the air conditioning system to start based on the wind speed of the air conditioning system, and controls the power battery to provide power for the air conditioning system.

[0118] In the embodiment of the present application, after the external circulation fan has been running for a period of time, the temperature inside the vehicle will drop to a certain extent. At this time, turning on the air conditioning system can greatly reduce energy consumption. In addition, when turning on the air conditioning system, different power sources can be controlled to provide power for the air conditioning system according to the vehicle type and its driving mode. At the same time, the wind speed of the air conditioning system is determined according to the temperature difference between the current temperature inside the vehicle and the set temperature, and the air conditioning system is turned on based on the wind speed. In this way, when the air conditioning system is running, it does not need to work at a high load, which can further reduce energy consumption.

[0119] In the embodiment of the present application, when the vehicle controller controls the air conditioning system to turn on, it sends an on command to the air conditioning system, and the air conditioning system is adjusted to the on state based on the on command. After the air conditioning system is turned on, the air conditioning system can send a notification message to the vehicle controller, and the vehicle controller determines that the state of the air conditioning system is the on state based on the notification message.

[0120] One point that needs to be explained is that when the first temperature is greater than the second preset temperature, the vehicle controller can obtain the rainfall signal detected by the rain sensor; when the rainfall signal indicates that there is no rainfall, when the key signal is detected, the vehicle's multiple windows are controlled to be lowered to the lowest position, and the speed of the external circulation fan is controlled to be the third speed.

[0121] In this implementation, when the rainfall signal indicates that there is no rain, when the vehicle controller detects the key signal, it means that the user is approaching the vehicle. At this time, the vehicle controller can control multiple windows of the vehicle to the lowest position and control the speed of the external circulation fan to the third speed.

[0122] The process of the vehicle controller controlling the multiple windows to be lowered to the lowest position is the same as that in step 202, and will not be repeated here.

[0123] When the rainfall signal indicates rainfall, in order to prevent rain from entering the vehicle and damaging the components inside the vehicle, the vehicle controller can only control the speed of the external circulation fan to the third speed. The third speed is the maximum speed, which can quickly reduce the temperature inside the vehicle.

[0124] Another point that needs to be explained is that when the first temperature is lower than the third preset temperature, the vehicle controller can control the air conditioning system to turn on in any of the following ways.

[0125] In the first implementation method, when the first temperature is lower than the third preset temperature, the vehicle controller obtains the set temperature; based on the fourth temperature difference between the second temperature and the set temperature, the operating mode and wind speed of the air-conditioning system are determined; based on the operating mode and wind speed of the air-conditioning system, the air-conditioning system is controlled to turn on.

[0126] In this implementation, since the first temperature is lower than the third preset temperature, the temperature inside the vehicle is not much different from the temperature outside the vehicle, and the vehicle controller determines that the working mode of the air-conditioning system is the heating mode.

[0127] When the first temperature is less than the third preset temperature, the vehicle controller determines a fourth temperature difference between the second temperature and the set temperature.

[0128] When the fourth temperature difference is less than the sixth preset difference, the vehicle controller determines that the wind speed of the air conditioning system is the first wind speed; when the fourth temperature difference is greater than the sixth preset difference and less than the seventh preset difference, the wind speed of the air conditioning system is determined to be the second wind speed; when the fourth temperature difference is greater than the seventh preset difference, the wind speed of the air conditioning system is determined to be the third wind speed. The seventh preset difference is greater than the sixth preset difference.

[0129] The third preset temperature can be set and changed as needed, and is not specifically limited thereto. For example, the third preset temperature is 15° C. In addition, since the vehicle controller obtains the set temperature of the air conditioning system in step 201, it is not necessary to obtain it again here.

[0130] In an embodiment of the present application, when the first temperature is lower than the third preset temperature, the vehicle controller can determine the wind speed of the air-conditioning system according to the temperature difference between the second temperature in the vehicle and the set temperature, and turn on the air-conditioning system based on the wind speed. In this way, the air-conditioning system does not need to work at a high load when it is running, thereby reducing energy consumption.

[0131] The second implementation method is that when the first temperature is lower than the third preset temperature, the vehicle controller determines the vehicle type of the vehicle; when the vehicle type is a hybrid vehicle, the operating mode of the air-conditioning system and the driving mode of the vehicle are determined; based on the operating mode and the driving mode, the air-conditioning system is controlled to turn on.

[0132] In this implementation, since the first temperature is lower than the third preset temperature, the vehicle controller determines that the operating mode of the air-conditioning system is the heating mode.

[0133] Based on the working mode and driving mode, the vehicle controller can control the air conditioning system to start in the following way:

[0134] When the working mode is heating mode and the driving mode of the hybrid vehicle is pure electric driving mode, the vehicle controller controls the air-conditioning system to turn on, and controls the three-electric system to provide a heat source for the air-conditioning system through its coolant; among them, the three-electric system is a general term for the vehicle's battery, generator and electronic control system.

[0135] When the working mode is cooling mode and the driving mode of the hybrid vehicle is pure engine driving mode, the vehicle controller controls the air conditioning system to turn on, and controls the engine to provide a heat source for the air conditioning system through residual heat;

[0136] When the working mode is cooling mode and the driving mode of the hybrid vehicle is hybrid driving mode, the vehicle controller controls the air-conditioning system to turn on, and controls the engine to provide a heat source for the air-conditioning system through its residual heat, and / or controls the three-electric system to provide a heat source for the air-conditioning system through its coolant.

[0137] In an embodiment of the present application, when the first temperature is lower than the third preset temperature, the vehicle controller can make full use of the waste heat of the engine and the three-electric system according to the vehicle type and its driving mode to provide a heat source for the air-conditioning system, thereby reducing energy consumption.

[0138] A third implementation method is that when the first temperature is less than the third preset temperature, the vehicle controller determines the vehicle type of the vehicle; when the vehicle type is a hybrid vehicle, the operating mode of the air-conditioning system and the driving mode of the vehicle are determined; and based on the fourth temperature difference, the wind speed of the air-conditioning system is determined; based on the operating mode, driving mode and wind speed, the air-conditioning system is controlled to turn on.

[0139] In this implementation, the process of the vehicle controller determining the working mode and the driving mode is the same as that of the second implementation, and the process of determining the wind speed of the air-conditioning system is the same as that of the first implementation, which will not be repeated here.

[0140] The vehicle controller controls the air conditioning system to start based on the working mode, driving mode and wind speed. The process may be as follows: when the working mode is the heating mode and the driving mode of the hybrid vehicle is the pure electric driving mode, the vehicle controller controls the air conditioning system to start based on the wind speed of the air conditioning system, and controls the three-electric system to provide a heat source for the air conditioning system through its coolant;

[0141] When the working mode is cooling mode and the driving mode of the hybrid vehicle is pure engine driving mode, the vehicle controller controls the air conditioning system to turn on based on the wind speed of the air conditioning system, and controls the engine to provide a heat source for the air conditioning system through the residual heat;

[0142] When the working mode is cooling mode and the driving mode of the hybrid vehicle is hybrid driving mode, the vehicle controller controls the air-conditioning system to turn on based on the wind speed of the air-conditioning system, and controls the engine to provide a heat source for the air-conditioning system through its residual heat, and / or controls the three-electric system to provide a heat source for the air-conditioning system through its coolant.

[0143] In the embodiment of the present application, when the first temperature is lower than the third preset temperature, the vehicle controller can make full use of the waste heat of the engine and the three-electric system according to the vehicle type and its driving mode to provide a heat source for the air conditioning system, thereby reducing energy consumption. At the same time, the vehicle controller can also determine the wind speed of the air conditioning system according to the temperature difference between the second temperature in the vehicle and the set temperature, and turn on the air conditioning system based on the wind speed, so that the air conditioning system does not need to work at a high load when it is running, thereby further reducing energy consumption.

[0144] In an embodiment of the present application, when the first temperature is between the third preset temperature and the first preset temperature, the temperature inside the vehicle is not much different from the temperature outside the vehicle, and different users have different perceptions of temperature. In this case, the air-conditioning system can be controlled by the user.

[0145] In the embodiment of the present application, the vehicle controller can also feedback the temperature inside the vehicle to the user. The process can be: before the user enters the vehicle, the vehicle controller can obtain the temperature inside the vehicle in real time or periodically, send a feedback message to the terminal through the T-BOX, the feedback message carries the temperature inside the vehicle, and the terminal displays the feedback message, so that the user can clearly know the temperature inside the vehicle when seeing the feedback message.

[0146] See also Figure 3 , the terminal obtains the vehicle's usage time and the set temperature of the air conditioner, and sends the usage time and set temperature to the vehicle controller through T-BOX. The outside temperature sensor sends the outside temperature to the vehicle controller, and the inside temperature sensor sends the inside temperature to the vehicle controller. Based on the outside temperature, inside temperature, usage time and set temperature, the vehicle controller first controls the external circulation fan to turn on and / or controls multiple windows to lower, and then controls the air conditioning system to turn on. In addition, the vehicle controller can also feedback the inside temperature to the terminal through T-BOX. In addition, after the air conditioning system is turned on, a notification message can also be sent to the vehicle controller.

[0147] The embodiment of the present application provides a vehicle air conditioning control method. When the temperature outside the vehicle is greater than a first preset temperature, the method determines the rotation speed of the vehicle's external circulation fan based on the temperature difference between the inside and outside of the vehicle. When the external circulation fan runs for a period of time based on the rotation speed, the current temperature inside the vehicle is obtained. When the current temperature is still greater than the temperature outside the vehicle, the rotation speed of the external circulation fan is adjusted. When the external circulation fan runs for a period of time based on the adjusted rotation speed, the air conditioning system is controlled to turn on. It can be seen that before turning on the air conditioning system, the method first turns on the external circulation fan, and reduces the temperature inside the vehicle to a certain extent through the external circulation fan, so that the air conditioning system will not work at a high load, thereby reducing the energy consumption of the vehicle; at the same time, since the air conditioning system is turned on, the temperature inside the vehicle can be kept at a suitable temperature. Therefore, this method can both reduce the energy consumption of the vehicle and keep the temperature inside the vehicle at a suitable temperature.

[0156] In another possible implementation, the first control module 405 is used to determine the vehicle type of the vehicle when the duration for which the external circulation fan runs at an adjusted speed reaches a second preset duration; when the vehicle type is a hybrid vehicle, determine the operating mode of the air-conditioning system and the driving mode of the vehicle; and control the air-conditioning system to turn on based on the operating mode and the driving mode.

[0159] The second control module is used to control the multiple windows of the vehicle to be lowered to the lowest position and control the speed of the external circulation fan to a third speed when the rainfall signal indicates that there is no rainfall.

[0161] A third acquisition module, configured to acquire a set temperature of the air-conditioning system when the first temperature is lower than a third preset temperature, and the third preset temperature is lower than the first preset temperature;

[0162] a second determination module, configured to determine an operating mode and a wind speed of the air conditioning system based on a fourth temperature difference between the second temperature and the set temperature;

[0163] The third control module is used to control the air conditioning system to start based on the working mode and wind speed of the air conditioning system.

[0164] The embodiment of the present application provides a vehicle air conditioning control device, which, when the temperature outside the vehicle is greater than a first preset temperature, determines the rotation speed of the vehicle's external circulation fan based on the temperature difference between the inside and outside of the vehicle, obtains the current temperature inside the vehicle after the external circulation fan runs for a period of time based on the rotation speed, and adjusts the rotation speed of the external circulation fan when the current temperature is still greater than the temperature outside the vehicle, and controls the air conditioning system to turn on after the external circulation fan runs for a period of time based on the adjusted rotation speed. It can be seen that before turning on the air conditioning system, the device first turns on the external circulation fan, and reduces the temperature inside the vehicle to a certain extent through the external circulation fan, so that the air conditioning system will not work at a high load, thereby reducing the energy consumption of the vehicle; at the same time, since the air conditioning system is turned on, the temperature inside the vehicle can be kept at a suitable temperature.
