Description

Technical Field

[0001] This application belongs to the field of vehicle control technology, and specifically relates to a method and system for drying clothes using a car. Background Technology

[0002] Cars have become the main mode of transportation for outdoor activities. However, during car travel, there is a high possibility of encountering emergencies such as heavy rain, which may cause clothes to get wet. In such cases, it is necessary to dry the wet clothes as soon as possible during the trip.

[0003] Currently, the common practice for travelers to dry wet clothes is to hang them inside the car and use the air conditioning's heating system. However, due to the limited space inside a car, wet clothes generally cannot be fully spread out, and the air conditioning's heating system, limited by the size of the air vents, cannot dry the clothes evenly. Furthermore, depending on the season or weather, prolonged use of the heating system to dry wet clothes can lead to excessively high temperatures inside the car, causing discomfort for passengers. Summary of the Invention

[0004] To address the aforementioned problems, this application provides a method and system for drying clothes in a car, which has the beneficial effects of ensuring drying effect, improving drying efficiency, and enhancing the comfort of drivers and passengers.

[0005] One method for drying clothes using a car air dryer includes the following steps: Acquire outdoor temperature data and engine coolant temperature data; Based on the outdoor temperature data and the engine coolant temperature data, the cooling fan is driven to reverse and blow air through the heat dissipation structure toward the vehicle body's vents. The item to be dried is placed outside the vehicle body with the air vent facing it, and is dried by blowing air.

[0006] Furthermore, the step of driving the cooling fan to reverse direction based on the outdoor temperature data and the engine coolant temperature data, and blowing air through the radiator and condenser of the heat dissipation structure toward the vehicle's vents, includes the following steps: Obtain the comparison result between the outdoor temperature data and the first preset temperature; When the outdoor temperature data is lower than the first preset temperature, the cooling fan is deactivated from reversing.

[0007] Furthermore, the step of driving the cooling fan to reverse direction based on the outdoor temperature data and the engine coolant temperature data, and blowing air through the radiator and condenser of the heat dissipation structure toward the vehicle's vents, includes the following steps: Obtain the comparison result between the outdoor temperature data and the first preset temperature; When the outdoor temperature data is greater than the first preset temperature, the engine coolant temperature data and the comparison result of the second preset temperature are obtained; Based on the comparison between the engine coolant temperature data and the second preset temperature, the cooling fan is driven to start and reverse.

[0008] Furthermore, the step of driving the cooling fan to start and reverse based on the comparison result between the engine coolant temperature data and the second preset temperature includes the following steps: When the engine coolant temperature data is greater than the second preset temperature, the cooling fan is driven to start and reverse, blowing air through the condenser of the heat dissipation structure toward the air vents of the vehicle body; When the engine coolant temperature is lower than the second preset temperature, the cooling fan is activated and reversed, blowing air through the condenser of the heat dissipation structure toward the vehicle's vents. At the same time, the air conditioning compressor and blower are activated.

[0009] Furthermore, the step of driving the cooling fan to reverse direction based on the outdoor temperature data and the engine coolant temperature data, and blowing air through the radiator and condenser of the heat dissipation structure toward the vehicle's vents, includes the following steps: When the air conditioning compressor and blower are in the start-up state, the engine water temperature data and the comparison result of the third preset temperature are obtained; When the engine coolant temperature exceeds the third preset temperature, the air conditioning compressor and the blower are shut down, while the cooling fan continues to reverse, blowing air through the radiator and condenser of the heat dissipation structure toward the vehicle's vents.

[0010] Furthermore, acquiring outdoor temperature data and engine coolant temperature data includes the following steps: Acquire the outdoor temperature data and the comparison result between the outdoor temperature data and the first preset temperature; When the outdoor temperature data is greater than the first preset temperature, the engine coolant temperature data is obtained.

[0011] Further, the object to be dried is placed outside the vehicle body facing the vent, including the following steps: The air vent is formed through the air intake and the grille of the vehicle body; The object to be dried is placed on the outside of the vehicle body, facing the air intake or the grille.

[0012] A system based on the same concept for drying clothes in a car includes: Temperature detection unit is used to acquire outdoor temperature data and engine coolant temperature data; The mode control unit is used to drive the cooling fan to reverse and blow air through the heat dissipation structure toward the vents of the vehicle body based on the outdoor temperature data and the engine coolant temperature data.

[0013] Furthermore, the temperature detection unit is equipped with a comparison module; The comparison module is used to obtain the comparison result between the outdoor temperature data and the first preset temperature; The comparison module is used to obtain the engine coolant temperature data and the comparison result of the second preset temperature; The comparison module is used to obtain the comparison result between the engine coolant temperature data and the third preset temperature.

[0014] Furthermore, when the outdoor temperature data is greater than the first preset temperature and the engine coolant temperature data is less than the second preset temperature, the mode control unit drives the cooling fan to start and reverse, blowing air through the condenser of the heat dissipation structure toward the air vents of the vehicle body. At the same time, the mode control unit drives the air conditioning compressor and blower to start. When the air conditioning compressor and blower are running and the engine coolant temperature is greater than the third preset temperature, the mode control unit drives the air conditioning compressor and blower to shut down, and the mode control unit drives the cooling fan to keep reversing, blowing air through the radiator and condenser of the heat dissipation structure toward the air vents of the vehicle body.

[0015] Compared with the prior art, this application has the following advantages: This application's method for drying clothes in a car utilizes acquired outdoor temperature and engine coolant temperature data to drive the cooling fan in reverse. This allows the cooling fan to carry heat dissipated by the heat dissipation structure and blow it through the vents onto the items placed outside the vehicle to dry. This avoids the space limitations of the vehicle's interior, allowing the items to be fully extended outside the vehicle. It also overcomes the size limitations of air conditioning vents, ensuring even drying and improving efficiency. Furthermore, the absence of airflow inside the vehicle prevents excessively high interior temperatures, enhancing passenger comfort.

[0016] The system for drying clothes by car described in this application has the same beneficial effects as the method for drying clothes by car described above, so it will not be described again here.

[0017] Other features and advantages of this application will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the application. The objectives and other advantages of this application may be realized and obtained by means of the structures pointed out in the description, claims and drawings. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 and Figure 2 The embodiments of this application provide a method for drying clothes by air drying in a car, comprising the following steps: Acquire outdoor temperature data and engine coolant temperature data. Based on the outdoor temperature data and engine coolant temperature data, drive the cooling fan 6 to reverse and blow air through the heat dissipation structure toward the vent 9 of the vehicle body. Place the object to be dried 10 toward the vent 9 on the outside of the vehicle body, and dry the object 10 by blowing air.

[0023] Specifically, outdoor temperature data and engine coolant temperature data are detected and acquired. Based on the acquired outdoor temperature data and engine coolant temperature data, the cooling fan 6 can be reversed, so that the cooling fan 6 carries the heat emitted by the heat dissipation structure and blows it to the outside of the vehicle through the vent 9. The object to be dried 10 is placed outside the vehicle facing the vent 9, so that the air blown out by the cooling fan 6 can carry the heat emitted by the heat dissipation structure and dissipate it from the object to be dried 10, thereby achieving the drying of the object to be dried 10. By reversing the direction of the cooling fan 6 to blow air outside the vehicle body, the space limitations inside the vehicle body can be avoided, allowing the item to be dried 10 to be fully spread out outside the vehicle body. Furthermore, the cooling fan 6 carries the heat dissipation structure and blows it out of the vehicle body through the vent 9, which can overcome the size limitations of the air conditioning vents inside the vehicle body, so as to dry the item to be dried 10 evenly, ensuring the drying effect and improving the drying efficiency. At the same time, by placing the item to be dried 10 outside the vehicle body for drying, there is no need to blow air inside the vehicle body, which can avoid the temperature inside the vehicle body becoming too high due to blowing air inside the vehicle body, thus improving the comfort of the driver and passengers.

[0024] In some specific embodiments of this application, reference is made to Figure 1 Based on outdoor temperature data and engine coolant temperature data, the cooling fan 6 is driven to reverse, and air is blown towards the vehicle body's vent 9 through the radiator 7 and condenser 8 of the heat dissipation structure, including the following steps: Obtain the comparison result between the outdoor temperature data and the first preset temperature. When the outdoor temperature data is lower than the first preset temperature, cancel the reverse rotation of the cooling fan 6.

[0025] Specifically, the outdoor temperature data is compared with a first preset temperature to obtain a comparison result. When the comparison result shows that the outdoor temperature data is lower than the first preset temperature, it indicates that the environment does not meet the conditions for drying the object to be dried 10. In this case, the reverse rotation of the cooling fan 6 will be canceled. In a specific embodiment of this application, the comparison unit of the temperature detection unit can compare the outdoor temperature data with the first preset temperature and send the comparison result to the engine ECU5 of the mode control unit. If the outdoor temperature data is lower than the first preset temperature, the engine ECU5 cancels the reverse rotation of the cooling fan 6 and sends the command to cancel the reverse rotation of the cooling fan 6 to the air conditioning controller 4. The air conditioning controller 4 then causes the air conditioning display to show that the front air blowing mode cannot be turned on.

[0026] In some specific embodiments of this application, reference is made to Figure 1Based on outdoor temperature data and engine coolant temperature data, the cooling fan 6 is driven to reverse, and air is blown towards the vehicle body's vent 9 through the radiator 7 and condenser 8 of the heat dissipation structure, including the following steps: The system compares the outdoor temperature data with a first preset temperature. When the outdoor temperature is higher than the first preset temperature, it compares the engine coolant temperature data with a second preset temperature. Based on the comparison of the engine coolant temperature data and the second preset temperature, it drives the cooling fan 6 to start and reverse.

[0027] Specifically, the outdoor temperature data is compared with the first preset temperature to obtain the comparison result. When the comparison result shows that the outdoor temperature data is greater than the first preset temperature, it indicates that the environment meets the conditions for drying the object to be dried 10. At this time, the engine water temperature data is compared with the second preset temperature to obtain the comparison result. Based on the comparison result of the engine water temperature data and the second preset temperature, it is determined whether the heat emitted by the heat dissipation structure meets the conditions for drying the object to be dried 10, thereby driving the cooling fan 6 to start and reverse, so as to achieve the drying of the object to be dried 10. In the embodiments of this application, the comparison unit of the temperature detection unit can compare the outdoor temperature data with the first preset temperature and send the comparison result of the outdoor temperature data and the first preset temperature to the engine ECU5. If the outdoor temperature data is greater than the first preset temperature, the engine ECU5 sends an instruction to the comparison unit of the temperature detection unit to compare the engine coolant temperature data with the second preset temperature. Then, the comparison unit of the temperature detection unit compares the engine coolant temperature data with the second preset temperature and sends the comparison result of the engine coolant temperature data and the second preset temperature to the engine ECU5, so that the engine ECU5 drives the cooling fan 6 to start and reverse according to the comparison result of the engine coolant temperature data and the second preset temperature.

[0028] Furthermore, the first preset temperature is 8 degrees Celsius (the first preset temperature can be calibrated). If the outdoor temperature is less than 8 degrees Celsius, it means that the environment does not meet the conditions for drying the object 10, so the reverse rotation of the cooling fan 6 is canceled. If the outdoor temperature is greater than 8 degrees Celsius, it means that the environment meets the conditions for drying the object 10, so the subsequent steps are performed.

[0029] Furthermore, if the outdoor temperature data is greater than the first preset temperature, it indicates that the environment meets the conditions for drying the object to be dried 10. At this time, the engine ECU5 sends a command to the air conditioning controller 4 to drive the cooling fan 6 to reverse. The air conditioning controller 4 drives the air conditioning display to show that the front air blowing mode has been turned on, or the air conditioning controller 4 drives the switch indicator light of the front air blowing mode to light up.

[0030] In some specific embodiments of this application, reference is made to Figure 1 Based on the comparison between engine coolant temperature data and a second preset temperature, the cooling fan 6 is driven to start and reverse, including the following steps: When the engine coolant temperature exceeds the second preset temperature, the cooling fan 6 is activated and reversed, blowing air through the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body. When the engine coolant temperature is below the second preset temperature, the cooling fan 6 is activated and reversed, blowing air through the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body. At the same time, the air conditioning compressor 11 and the blower are activated.

[0031] Specifically, if the engine coolant temperature is higher than the second preset temperature, it means that the heat provided by the engine is sufficient to dry the object to be dried 10. In this case, only the cooling fan 6 needs to be started and reversed, and the air blown through the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body. If the engine coolant temperature is lower than the second preset temperature, it means that the heat provided by the engine is insufficient to dry the object to be dried 10. In this case, not only does the cooling fan 6 need to be started and reversed, and the air blown through the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body, but the air conditioning compressor 11 and the blower also need to be started. This lays the foundation for the radiator 7 of the heat dissipation structure to cool the air conditioning compressor 11 and the blower, thereby ensuring the drying effect and drying efficiency. In the embodiments of this application, the engine coolant temperature data and the second preset temperature are compared by the comparison unit of the temperature detection unit, and the comparison result of the engine coolant temperature data and the second preset temperature is sent to the engine ECU 5. If the engine coolant temperature is higher than the second preset temperature, the engine ECU5 sends a start and reverse command to the cooling fan 6 via the LIN bus. This only drives the cooling fan 6 to start and reverse, blowing air through the condenser 8 (used for cooling the engine) towards the vent 9 on the vehicle body. If the engine coolant temperature is lower than the second preset temperature, in addition to sending the start and reverse command to the cooling fan 6 via the LIN bus, the engine ECU5 also needs to start the air conditioning compressor 11 and send a start signal to the air conditioning controller 4 via the CAN bus. When the air conditioning controller 4 receives the start signal from the engine ECU5, it starts the blower to operate.

[0032] Furthermore, the second preset temperature is 30 degrees Celsius (the second preset temperature can be calibrated). If the engine coolant temperature is greater than 30 degrees Celsius, it means that the heat provided by the engine is sufficient to dry the object to be dried 10, and only the cooling fan 6 is started and reversed. If the engine coolant temperature is less than 30 degrees Celsius, it means that the heat provided by the engine is insufficient to dry the object to be dried 10, and in addition to starting and reversing the cooling fan 6, the air conditioning compressor 11 and the blower also need to be started (the speed of the blower can be calibrated).

[0033] Furthermore, after receiving the start and reverse command from the engine ECU 5, the cooling fan 6 controls the fan to rotate in reverse through its internal circuitry (the fan speed can be calibrated). When the cooling fan 6 starts and reverses, the fan can draw in air from the engine compartment by rotating. The heat generated by the condenser 8, which is used to dissipate heat from the engine, is blown towards the front of the vehicle through the air vents 9 formed by the air intakes on the vehicle's grille and front bumper. At this time, the object to be dried 10 can be placed in front of the vehicle, and the blown hot air can dry the object or warm the body of the passengers.

[0034] In some specific embodiments of this application, reference is made to Figure 1 Based on outdoor temperature data and engine coolant temperature data, the cooling fan 6 is driven to reverse, and air is blown towards the vehicle body's vent 9 through the radiator 7 and condenser 8 of the heat dissipation structure, including the following steps: When the air conditioning compressor 11 and blower are running, the engine coolant temperature data is compared with the third preset temperature. When the engine coolant temperature data is greater than the third preset temperature, the air conditioning compressor 11 and blower are turned off, the cooling fan 6 continues to reverse, and air is blown towards the air vent 9 of the vehicle body through the radiator 7 and condenser 8 of the heat dissipation structure.

[0035] Specifically, when the air conditioning compressor 11 and blower are running, the engine coolant temperature data is monitored in real time and compared with a third preset temperature to obtain the comparison result. If the engine coolant temperature is lower than the third preset temperature, the air conditioning compressor 11 and blower remain running. If the engine coolant temperature is higher than the third preset temperature, it indicates that the radiator 7, used to dissipate heat from the air conditioning compressor 11 and blower, has sufficient heat. In this case, the air conditioning compressor 11 and blower are shut off, while the cooling fan 6 continues to reverse. This allows the cooling fan 6 to blow air through the radiator 7 and condenser 8 of the heat dissipation structure towards the vehicle's vent 9. This allows the hot air carrying the heat dissipated by the radiator 7 and condenser 8 to dry the items 10 or to warm the bodies of the passengers, thereby further ensuring the drying effect and improving drying efficiency. In the embodiments of this application, when the air conditioning compressor 11 and the blower are in the starting state, the engine coolant temperature data is detected in real time by the engine coolant temperature sensor 2, and the engine coolant temperature data is compared with a third preset temperature by the comparison unit of the temperature detection unit. The comparison result of the engine coolant temperature data and the third preset temperature is obtained and sent to the engine ECU 5. If the engine coolant temperature data is lower than the third preset temperature, the engine ECU 5 does not need to take any action and can continue to keep the air conditioning compressor 11 and the blower in the starting state. If the engine coolant temperature data is higher than the third preset temperature, the engine ECU 5 shuts down the air conditioning compressor 11 and sends the information that the air conditioning compressor 11 is shut down to the air conditioning controller 4 via the CAN bus. When the air conditioning controller 4 receives the message from the engine ECU 5 indicating that the air conditioning compressor 11 is off, the air conditioning controller 4 shuts down the blower. At this time, the coolant in the radiator 7, which is used to dissipate heat from the air conditioning compressor 11 and the blower, begins to circulate. The cooling fan 6 remains running and reverses, drawing air from the engine compartment. The heat generated by the radiator 7 (for cooling the air conditioning compressor 11 and the blower) and the heat generated by the condenser 8 (for cooling the engine) are blown towards the front of the vehicle through the air intake 9 formed by the air intakes on the vehicle's grille and front bumper. At this time, the item to be dried 10 can be placed in front of the vehicle, allowing the blown hot air to dry the item or warm the body of the passengers. By introducing a cooling structure into the radiator 7 for cooling the air conditioning compressor 11 and the blower, the temperature of the blown hot air is increased, thus quickly drying the item or warming the body of the passengers, further ensuring the drying effect and improving drying efficiency.

[0036] Furthermore, the third preset temperature is 70 degrees Celsius (the third preset temperature can be calibrated). If the engine coolant temperature is less than 70 degrees Celsius, it indicates that the radiator 7 used to dissipate heat from the air conditioning compressor 11 and the blower is not hot enough, so the air conditioning compressor 11 and the blower should remain running. If the engine coolant temperature is greater than 70 degrees Celsius, it indicates that the radiator 7 used to dissipate heat from the air conditioning compressor 11 and the blower is hot enough, so the radiator 7, which is used to dissipate heat from the air conditioning compressor 11 and the blower, should be used to dry the object to be dried.

[0037] In some specific embodiments of this application, reference is made to Figure 1 To obtain outdoor temperature data and engine coolant temperature data, the following steps are included: Acquire outdoor temperature data and compare it with a first preset temperature. When the outdoor temperature is higher than the first preset temperature, acquire engine coolant temperature data.

[0038] Specifically, outdoor temperature data is acquired, and a comparison result between the outdoor temperature data and a first preset temperature is obtained. When the outdoor temperature data is greater than the first preset temperature, engine coolant temperature data is then acquired. This reduces the interaction process between components, avoiding unnecessary detection or comparison processes. In the embodiments of this application, outdoor temperature data is detected and acquired by the outdoor temperature sensor 1 of the temperature detection unit, and sent to the comparison unit of the temperature detection unit. The comparison unit of the temperature detection unit can compare the outdoor temperature data with the first preset temperature and send the comparison result to the engine ECU5 of the mode control unit. If the outdoor temperature data is greater than the first preset temperature, the engine ECU5 sends a command to the engine coolant temperature sensor 2 of the temperature detection unit to start detecting engine coolant temperature data.

[0039] Furthermore, before acquiring outdoor temperature data and engine coolant temperature data, the following steps are set: start the engine, press the front air blower switch 3 on the air conditioning panel, and send a work request signal to the air conditioning controller 4, thereby putting the engine ECU 5 and the air conditioning controller 4 into working state so as to carry out subsequent steps.

[0040] Furthermore, after the object to be dried 10 has dried completely or after the body temperature of the driver and passengers has risen, press the front air blower switch 3 on the air conditioning panel again to turn off the front air blower mode indicator light of the air conditioning controller 4. At the same time, the air conditioning controller 4 sends a signal to the engine ECU 5 to turn off the front air blower mode via the CAN bus.

[0041] Furthermore, after receiving the signal from the air conditioning controller 4 indicating that the front air blowing mode is off, the engine ECU 5 sends a command to the cooling fan 6 via the LIN line to shut down the cooling fan 6, causing the cooling fan 6 to stop and turn off.

[0042] Furthermore, after receiving the command from the engine ECU 5 to shut down the cooling fan 6, the cooling fan 6 stops and shuts down, and finally the engine is shut down, thus ending the entire process of drying clothes by blowing them in the car.

[0043] In some specific embodiments of this application, reference is made to Figure 1 Place the dried object 10 facing the vent 9 on the outside of the vehicle body, including the following steps: Air vents 9 are formed through the air intake and grille of the vehicle body. The object to be dried 10 is placed on the outside of the vehicle body with the air intake or grille facing it.

[0044] Specifically, the vent 9 is formed by the combination of the vehicle's grille and the air intake on the front bumper. Hot air is blown towards the front of the vehicle through the vent 9 formed by the air intake on the grille and front bumper. Placing the item to be dried 10 at the front of the vehicle allows the blown hot air to dry the item or warm the body of the passengers. The vent 9, formed by the grille and front bumper, allows air to blow towards the front of the vehicle, avoiding the space limitations of the interior and allowing the item to be dried 10 to be fully spread out at the front. It also overcomes the size limitations of the air conditioning vents inside the vehicle, ensuring even drying of the item and improving drying efficiency. Furthermore, by placing the item to be dried at the front of the vehicle for drying, there is no need for air to blow inside the vehicle, avoiding excessively high temperatures inside the vehicle and improving passenger comfort.

[0045] Reference Figure 1 and Figure 2 This application provides a system for drying clothes in a car, comprising: a temperature detection unit and a mode control unit. The temperature detection unit is used to acquire outdoor temperature data and engine coolant temperature data. The mode control unit is used to drive the cooling fan 6 in reverse based on the outdoor temperature data and engine coolant temperature data, and blow air through the heat dissipation structure toward the vent 9 of the vehicle body.

[0046] Specifically, the outdoor temperature sensor 1 of the temperature detection unit detects and acquires outdoor temperature data, and the engine coolant temperature sensor 2 of the temperature detection unit detects and acquires engine coolant temperature data. Based on the outdoor temperature data and engine coolant temperature data, the engine ECU 5 of the mode control unit drives the cooling fan 6 to reverse direction, blowing air through the heat dissipation structure towards the vent 9 of the vehicle body. By reversing the direction of the cooling fan 6 to blow air outside the vehicle body, the space limitations inside the vehicle body can be avoided, allowing the item to be dried 10 to be fully spread out outside the vehicle body. Furthermore, the cooling fan 6 carries the heat dissipated by the heat dissipation structure and blows it outside the vehicle body through the vent 9, overcoming the size limitations of the air conditioning vents inside the vehicle body, thus ensuring uniform drying of the item to be dried 10, guaranteeing drying effect, and improving drying efficiency. At the same time, by placing the item to be dried 10 outside the vehicle body for drying, there is no need for air blowing inside the vehicle body, avoiding excessively high temperatures inside the vehicle body caused by air blowing inside, and improving the comfort of the passengers.

[0047] In some specific embodiments of this application, reference is made to Figure 2 The temperature detection unit includes a comparison module. This module compares the outdoor temperature data with a first preset temperature. It also compares the engine coolant temperature data with a second preset temperature. Finally, it compares the engine coolant temperature data with a third preset temperature.

[0048] Specifically, the temperature detection unit includes a comparison module. This comparison module compares the outdoor temperature data with a first preset temperature, obtains the comparison result, and sends it to the engine ECU 5 (mode control unit). If the outdoor temperature is lower than the first preset temperature, the engine ECU 5 cancels the reversal of the cooling fan 6 and sends this command to the air conditioning controller 4. The air conditioning controller 4 then causes the air conditioning display to show that the front airflow mode is disabled. If the outdoor temperature is higher than the first preset temperature, the comparison module compares the engine coolant temperature data with a second preset temperature. This comparison module compares the engine coolant temperature data with the second preset temperature, obtains the comparison result, and sends it to the engine ECU 5. The engine ECU 5 then activates and reverses the cooling fan 6 based on the comparison result. When the air conditioning compressor 11 and the blower are in the start-up state, the comparison unit of the temperature detection unit can compare the engine water temperature data with the third preset temperature, obtain the comparison result of the engine water temperature data and the third preset temperature and send it to the mode control unit engine ECU5. The engine ECU5 adjusts the working state of the air conditioning compressor 11 and the blower according to the comparison result of the engine water temperature data and the third preset temperature.

[0049] Furthermore, the outdoor temperature sensor 1 of the temperature detection unit detects and acquires outdoor temperature data, and sends this data to the comparison unit of the temperature detection unit. The comparison unit compares the outdoor temperature data with a first preset temperature and sends the comparison result to the engine ECU 5 of the mode control unit. If the outdoor temperature is higher than the first preset temperature, the engine ECU 5 sends a command to the engine coolant temperature sensor 2 of the temperature detection unit to start detecting engine coolant temperature data. The engine coolant temperature sensor 2 detects and acquires the engine coolant temperature data, and sends it to the comparison unit of the temperature detection unit. The comparison unit then compares the engine coolant temperature data with a second preset temperature. This reduces the interaction between components, avoiding unnecessary detection or comparison processes.

[0050] In some specific embodiments of this application, reference is made to Figure 2When the outdoor temperature is higher than the first preset temperature and the engine coolant temperature is lower than the second preset temperature, the mode control unit drives the cooling fan 6 to start and reverse, blowing air through the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body. At the same time, the mode control unit drives the air conditioning compressor 11 and the blower to start. When the air conditioning compressor 11 and the blower are running and the engine coolant temperature is higher than the third preset temperature, the mode control unit drives the air conditioning compressor 11 and the blower to shut down, and the mode control unit drives the cooling fan 6 to continue reversing, blowing air through the radiator 7 and the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body.

[0051] Specifically, the comparison unit of the temperature detection unit can compare the outdoor temperature data with a first preset temperature and send the comparison result to the engine ECU5 of the mode control unit. If the outdoor temperature data is greater than the first preset temperature, the engine ECU5 sends a command to the comparison unit of the temperature detection unit to compare the engine coolant temperature data with the second preset temperature. The comparison unit of the temperature detection unit then compares the engine coolant temperature data with the second preset temperature and sends the comparison result to the engine ECU5. If the engine coolant temperature data is greater than the second preset temperature, the engine ECU5 sends a command to the cooling fan 6 via the LIN bus to start and reverse it. This only drives the cooling fan 6 to start and reverse, and blows air through the condenser 8 of the heat dissipation structure towards the vent 9 of the vehicle body. If the engine coolant temperature is lower than the second preset temperature, the engine ECU5 needs to send a start and reverse command to the cooling fan 6 via the LIN bus to drive the cooling fan 6 to start and reverse. The engine ECU5 also needs to start the air conditioning compressor 11 and send a start signal for the air conditioning compressor 11 to the air conditioning controller 4 via the CAN bus. When the air conditioning controller 4 receives the start signal from the engine ECU5, it starts the blower. When the air conditioning compressor 11 and blower are running, the comparison unit of the temperature detection unit compares the engine coolant temperature with the third preset temperature, obtains the comparison result, and sends it to the mode control unit, the engine ECU5. If the engine coolant temperature is lower than the third preset temperature, the engine ECU5 does not need to take any action and simply keeps the air conditioning compressor 11 and blower running. If the engine coolant temperature is higher than the third preset temperature, the engine ECU5 shuts down the air conditioning compressor 11 and sends a shutdown message to the air conditioning controller 4 via the CAN bus. When the air conditioning controller 4 receives the information from the engine ECU 5 that the air conditioning compressor 11 is turned off, the air conditioning controller 4 shuts down the blower. At this time, the coolant in the radiator 7, which is used to cool the air conditioning compressor 11 and the blower, begins to circulate. The engine ECU 5 keeps the cooling fan 6 running and in reverse. The fan of the cooling fan 6 can draw in air from the engine compartment by rotating. The heat generated by the radiator 7, which is used to cool the air conditioning compressor 11 and the blower, and the heat generated by the condenser 8, which is used to cool the engine, are blown towards the front of the vehicle through the air vents 9 formed by the air intakes on the vehicle's grille and front bumper.
