Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a fan, a control method for a vehicle fan, a control module for a vehicle fan, a vehicle, and a computer-readable storage medium. Background Art

[0002] With the development of new energy vehicles, thermal management technology of new energy vehicles is becoming more and more important. Therefore, the thermal management system composed of components such as radiators and fans has gradually become the design focus of new energy vehicles.

[0003] In the thermal management system, the fan is used to deliver wind of corresponding gear (or intensity) according to the heat dissipation requirements, so as to cooperate with the radiator to dissipate heat for various components in the vehicle. In order to realize the gear control of the fan, multiple relays and electronic controllers are usually installed in the vehicle. However, at this stage, more and more devices such as sensors and controllers are installed in vehicles. The solution of setting up relays needs to occupy a large space in the vehicle, which is not conducive to the layout of components and wiring in a limited space. Summary of the invention

[0004] The present application provides a fan, a control method for a vehicle fan, a control module for a vehicle fan, a vehicle, and a computer-readable storage medium.

[0005] The embodiment of the present application provides a fan for a vehicle, wherein the fan is connected to a controller of the vehicle, and the fan comprises:

[0006] Motor;

[0007] A fan blade connected to the motor;

[0008] a shift module connected to the motor, the shift module comprising at least one resistor, the controller comprising at least two switch devices, wherein one of the at least two switch devices is connected to the motor, and each of the other switch devices is connected to at least one of the resistors;

[0009] The fan is configured to be connected to a corresponding resistor according to the closing state of the switch device in the controller so that the motor drives the fan blades to rotate at a corresponding gear, wherein the closing state of the switch device is determined based on the operating condition information acquired by the controller.

[0010] In the fan provided in the embodiment of the present application, the fan is connected to the controller of the vehicle, the motor in the fan is connected to the fan blades, and the motor is also connected to the shift module. The shift module includes at least one resistor, and the controller includes at least two switching devices. At least one of the two switching devices is connected to the motor, and each of the other switching devices is connected to at least one of the resistors. The fan is configured to establish a connection between the motor and the resistor in the shift module through a closed or open resistor according to the closed state of the switching device determined by the controller through the operating condition information obtained, so as to drive the fan blades to rotate with the corresponding gear.

[0011] In this way, the embodiment of the present application uses a shift module composed of resistors to enable the fan gear control to be implemented in a smaller space inside the vehicle. At the same time, because the shift module can be completed in a smaller space inside the vehicle, compared with the solution of implementing gear control through relays, the embodiment of the present application improves the utilization rate of the space inside the vehicle to a certain extent, and also reduces the difficulty of arranging parts and wiring in the limited vehicle space. In addition, because the relay will emit a certain amount of noise when working, compared with the method of implementing gear control through relays, the embodiment of the present application also reduces the noise during the operation of the fan to a certain extent, thereby improving the user's driving experience.

[0012] In some embodiments, the shift module also includes a connector, which includes at least two groups of pins; one of the at least two switching devices is connected to the motor through one group of the at least two groups of pins, and each of the other switching devices is connected to at least one of the resistors through a group of the other pins.

[0013] In this way, the embodiment of the present application is based on the setting of the connector, so that the switching device and the resistor can be interconnected simply and efficiently.

[0014] In some embodiments, the fan is configured to be connected to a corresponding resistor according to the closed state of the switch device in the controller so that the motor drives the fan blades to rotate at a corresponding gear, wherein the closed state of the switch device is determined by the controller based on the acquired operating condition information and a preset mapping relationship between the operating condition information and the closed state of the switch device.

[0015] In this way, the implementation mode of the present application is based on the preset mapping relationship between the operating condition information and the closing state of the switching device, so that the controller can quickly determine or set the corresponding closing state of the switching device after obtaining the operating condition information, so that the motor can drive the fan blades at an appropriate gear, thereby ensuring efficient execution of heat dissipation in the vehicle.

[0016] In certain embodiments, the controller includes a front body domain controller;

[0017] The fan is configured to be connected to a corresponding resistor according to a closed state of the switch device in the controller so that the motor drives the fan blades to rotate at a corresponding gear, wherein the closed state of the switch device is determined by the front body domain controller based on an acquired gear shifting requirement and a current closed state of the switch device, and the gear shifting requirement is determined based on the operating condition information.

[0018] In this way, the implementation of the present application enables the front body domain controller to quickly adjust the gear position of the fan based on the determination of the gear shifting requirement, that is, to adjust the current closed state of the switch device, so that the gear switching of the fan can be carried out efficiently. At the same time, because the implementation of the present application is based on the front body domain controller with higher computing power than the electronic control unit to realize the gear control of the fan, it can ensure to a certain extent that the fan can change gear in a timely or reliable manner, and the heat dissipation effect in the car is improved to a certain extent.

[0019] In certain embodiments, the shift demand is determined by the vehicle's power domain controller based on one or more combinations of collected drive motor temperature, electronic control temperature, and vehicle controller temperature, and / or by the vehicle's right body domain controller based on one or more combinations of collected vehicle battery power, vehicle air conditioning line pressure, and battery thermal management system line pressure.

[0020] In this way, the implementation method of the present application enables the power domain controller to determine that the fan needs to adjust the gear according to one or more combinations of the collected drive motor temperature, electronic control temperature and vehicle controller temperature, or the right body domain controller to determine that the fan needs to adjust the gear according to one or more combinations of the collected vehicle battery power, vehicle air conditioning pipeline pressure and battery thermal management system pipeline pressure. That is, the power domain controller or the right body domain controller determines that the fan gear needs to be changed based on the collected information, that is, when there is a gear shift requirement, the body domain controller can change the fan gear accordingly, so that the fan gear can be reasonably adjusted. At the same time, because the implementation method of the present application determines the fan gear shift requirement based on the power domain controller and the right body domain controller, or in other words, the determination of the gear shift requirement is determined by a device with a computing power higher than the electronic control unit, the credibility of the gear shift requirement can be guaranteed to a certain extent.

[0021] In some embodiments, the switching device is a metal oxide semiconductor field effect transistor.

[0022] In this way, the switching device composed of metal oxide semiconductor field effect transistors in the embodiment of the present application can further reduce the space inside the vehicle required to achieve fan gear control, thereby further reducing the difficulty of arranging components and wiring in the limited vehicle space.

[0023] The embodiment of the present application provides a method for controlling a vehicle fan, wherein the vehicle includes the above-mentioned fan, and the method includes:

[0024] Obtain working condition information;

[0025] The closed state of the switch device is determined according to the operating condition information to control the motor of the fan to drive the fan blades to rotate at a corresponding gear.

[0026] In this way, the controller of the embodiment of the present application uses a shift module composed of resistors to enable the fan gear control to be implemented in a smaller space inside the vehicle. At the same time, because the shift module can be completed in a smaller space inside the vehicle, compared with the scheme of implementing gear control through relays, the embodiment of the present application improves the utilization rate of the space inside the vehicle to a certain extent, and also reduces the difficulty of arranging parts and wiring in the limited vehicle space. In addition, because the relay will emit a certain noise when working, compared with the method of implementing gear control through relays, the embodiment of the present application also reduces the noise during the operation of the fan to a certain extent, thereby improving the user's driving experience.

[0027] In some embodiments, determining the closed state of the switch device according to the operating condition information to control the motor of the fan to drive the fan blades to rotate at a corresponding gear position includes:

[0028] The closed state of the switch device is determined according to the operating condition information and a preset mapping relationship between the operating condition information and the closed state of the switch device to control the motor of the fan to drive the fan blades to rotate at a corresponding gear.

[0029] In this way, the implementation mode of the present application is based on the preset mapping relationship between the operating condition information and the closing state of the switching device, so that the controller can quickly determine or set the corresponding closing state of the switching device after obtaining the operating condition information, so that the motor can drive the fan blades at an appropriate gear, thereby ensuring efficient execution of heat dissipation in the vehicle.

[0030] In some embodiments, determining the closed state of the switch device according to the operating condition information to control the motor of the fan to drive the fan blades to rotate at a corresponding gear position includes:

[0031] According to the acquired gear shifting requirement and the current closed state of the switch device, the closed state of the switch device is determined to control the motor of the fan to drive the fan blades to rotate at a corresponding gear, and the gear shifting requirement is determined based on the operating condition information.

[0032] In this way, the implementation mode of the present application enables the controller to quickly adjust the gear of the fan based on the determination of the gear shifting requirement, that is, to adjust the current closed state of the switching device so that the gear switching of the fan can be carried out efficiently.

[0033] The embodiment of the present application provides a control module for a vehicle fan, wherein the vehicle includes the above-mentioned fan, and the module includes:

[0034] A transceiver unit, used to obtain working condition information;

[0042] The vehicle fan control module, vehicle and computer-readable storage medium provided by the embodiment of the present application, and the shift module composed of resistors enable the gear control of the fan to be realized in a smaller space inside the vehicle. At the same time, because the shift module can be completed in a smaller space inside the vehicle, compared with the scheme of realizing gear control through relays, the embodiment of the present application improves the utilization rate of the space inside the vehicle to a certain extent, and also reduces the difficulty of arranging components and wiring in the limited vehicle space. In addition, because the relay will emit a certain noise when working, compared with the method of realizing gear control through relays, the embodiment of the present application also reduces the noise during the operation of the fan to a certain extent, thereby improving the user's driving experience.

[0055] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0056] The thermal management system is an indispensable part of new energy vehicles. It is used to manage (or regulate) the heat inside the vehicle during operation so that various components in the vehicle (such as the engine and power battery, etc.) can operate at an appropriate temperature.

[0057] Generally, thermal management systems are divided into water-cooled systems and air-cooled systems. The water-cooled system includes a radiator, a fan (or cooling fan), an electronic water pump, a coolant pump, and an electronic water valve. Among them, the radiator can control the coolant to absorb the heat of various components in the vehicle through the electronic water pump, the coolant pump, the electronic water valve and the pipeline to play the role of heat dissipation of the parts. Among them, in order to ensure that the coolant in the pipeline can effectively absorb the heat from the outside world (i.e., the parts inside the vehicle), the fan will send air to the radiator core of the radiator, so that the temperature of the coolant passing through the pipeline through the radiator core is reduced. Furthermore, the radiator can ensure stable heat dissipation based on the air supply of the fan.

[0058] Furthermore, when the temperature of the coolant is higher than a certain value, or in other words, the temperature of the parts inside the car has not dropped to a suitable temperature due to the operation of the radiator, the fan needs to send a stronger wind to the radiator core, that is, the fan needs to run at a high gear to ensure that the parts can dissipate heat in a timely and effective manner. Therefore, the gear control of the fan is also one of the important design links of the thermal management system.

[0059] To achieve the gear control of the fan, common methods include using a stepless speed fan and PWM (Pulse Width Modulation) control, and using two or more relays and an electronic controller. Among them, in the scheme of achieving gear control through a stepless speed fan and PWM control, both the stepless speed fan and PWM control require certain hardware costs, so the cost of implementing gear control is relatively high.

[0060] In the scheme of realizing gear position control through two or more relays and electronic controllers, although the unit cost of relays and electronic controllers is low, two or more relays need to occupy a larger space in the car. However, due to the continuous update and increase of user needs, there are more and more components in the car, such as sensors and controllers. Therefore, when realizing gear position control through two or more relays and electronic controllers, it is not conducive to completing the layout of various components and wiring in the limited space in the car. In addition, the relay will also generate a certain amount of noise when working. In other words, when the gear position control is realized through the relay, the noise of the relay working will also affect the user's driving experience.

[0061] For the above problems that may be encountered, please refer to Figure 1The present application provides a fan 100, which is connected to a controller 210 of a vehicle. The fan 100 includes: a motor 110, a fan blade 120 connected to the motor, and a shift module 130 connected to the motor 110. The shift module 130 includes at least one resistor 131, and the controller 210 includes at least two switch devices 211, wherein at least one of the two switch devices 211 is connected to the motor 110, and each of the other switch devices 211 is connected to at least one resistor 131. The fan 100 is configured to be connected to the corresponding resistor 131 according to the closed state of the switch device 211 in the controller 210, so that the motor 110 drives the fan blade 120 to rotate at the corresponding gear, wherein the closed state of the switch device 211 is determined according to the working condition information acquired by the controller 210.

[0062] To more clearly illustrate the fan 100 provided in the embodiment of the present application, please refer to Figure 2 and Figure 3 , Figure 2 This is a front plan view of the fan 100 in some embodiments of the present application. Figure 3 This is a top view of the back of the fan 100 in some embodiments of the present application. It should be noted that: Figure 2 and Figure 3 There is a fixing member 140 for fixing the fan, and the shape, structure and material of the fixing member 140 are all contents that can be set according to actual conditions. And, the fixing member 140 is a device that can be set according to actual conditions.

[0063] It should also be noted that the implementation mode of the present application is based on setting a shift module 130 composed of at least two resistors 131 in the fan 100, so that when the controller 210 determines that the fan 100 needs to run at a certain gear, the switch device 211 can be closed according to the gear, so that the motor 110 of the fan 100 establishes or disconnects the connection with the resistor 131 in the shift module 130 through the closed or open switch device 211, and then, the input voltage or input current of the motor 110 increases or decreases due to the connection status of the resistor 131, thereby driving the fan blades 120 to rotate at the corresponding gear.

[0064] For example, see Figure 4 , Figure 4 This is a schematic diagram of the circuit structure of a part of the vehicle in certain embodiments of the present application. Specifically, Figure 4 The controller 210 includes three switch devices 211, one of which is connected to the motor 110, and the remaining two are connected to the shift module 130 ( Figure 4In the embodiment of the present invention, the first embodiment of the present invention relates to a fan 100 having a plurality of motors 110 and a plurality of motors 120 connected to the fan 100. The first embodiment of the present invention relates to a fan 100 having a plurality of motors 110 connected to the fan 100 and a plurality of motors 120 connected to the fan 100. The first embodiment of the present invention relates to a fan 100 having a plurality of motors 110 connected to the fan 100 and a plurality of motors 120 connected to the fan 100. The first embodiment of the present invention relates to a fan 100 having a plurality of motors 110 connected to the fan 100 and a plurality of motors 120 connected to the fan 100. The first embodiment of the present invention relates to a fan 100 having a plurality of motors 110 connected to the fan 100 and a plurality of motors 120 connected to the fan 100.

[0065] When the controller 210 determines that the fan 100 needs to run at the "medium speed gear" based on the operating condition information, the first switch and the second switch can be closed, and the third switch can be opened. Then, when the first resistor 131 and the second resistor 131 are connected in parallel to the motor 110, the motor 110 can drive the fan blades 120 at the "medium speed gear", and the fan blades 120 deliver "medium speed wind".

[0066] When the controller 210 determines that the fan 100 needs to run at "high speed" based on the operating condition information, the first to third switches can be closed, and then the first resistor 131 and the second resistor 131 are short-circuited, which is equivalent to the motor 110 being directly connected to the power supply. Therefore, the motor 110 can drive the fan blades 120 at "high speed" and the fan blades 120 deliver "high-speed wind".

[0067] Therefore, the controller 210 of the embodiment of the present application controls the conduction of the switch device 211 so that the motor 110 of the fan 100 establishes or disconnects the connection with the resistor 131 through the switch device 211, and can drive the fan 100 at different gears, thereby realizing the gear control of the wind speed.

[0068] It is understood that the resistance values ​​of the resistors 131 in the embodiments of the present application may be the same or different. In some embodiments, to ensure that the motor 110 can work normally, the resistance value of each resistor 131 is not less than 0.25Ω and not more than 0.75Ω. In other embodiments, the resistance value of each resistor 131 is 0.5Ω.

[0069] Furthermore, in the embodiment where the resistance values ​​of the resistors 131 are different, the embodiment of the present application can also connect the motor 110 in series with the resistors 131 with different resistance values ​​to change the gear position. Figure 4On the basis of this, if the resistance value of the first resistor 131 is higher than the resistance value of the second resistor 131, when the controller 210 determines that the fan 100 needs to run at the "sub-medium speed gear" according to the operating condition information, the second switch can be closed, and the first switch and the third switch can be disconnected. Then, when the power supply, the motor 110 and the second resistor 131 form a current loop, the motor 110 can drive the fan blades 120 at the "sub-medium speed gear", and the fan blades 120 deliver "sub-medium speed wind".

[0070] It is also understandable that Figure 4 The illustrated case of three switch devices 211 and two resistors 131 is only one of the feasible implementations of the present application. The number of switch devices 211 and the number of resistors 131 in the implementation of the present application can be set according to actual conditions, and the number of resistors 131 connected to each switch device 211 can also be set according to actual conditions. At the same time, if more gears of fan 100 control are to be achieved, switch devices 211 and / or resistors 131 can be added according to actual conditions.

[0071] Exemplarily, in an embodiment where the resistance value of each resistor 131 is the same, Figure 4 The circuit shown can enable the fan 100 to deliver air at three different gears. To enable the fan 100 to deliver air at four gears, Figure 4 A switch device 211 and a resistor 131 are connected in parallel. For details, please refer to Figure 5 , Figure 5 Schematic diagram of the circuit structure of the vehicle in some embodiments of the present application. Figure 5 In the illustrated embodiment, one resistor 131 may be connected to the motor 110, or two resistors 131 may be connected in parallel and then connected to the motor 110, or three resistors 131 may be connected in parallel and then connected to the motor 110, or three resistors 131 may be short-circuited and then connected to the motor 110, thereby enabling the fan 100 to deliver air at four different gears.

[0072] In the embodiment where the resistance value of each resistor 131 is different, in order to enable the fan 100 to deliver air at four different gears, Figure 4 A resistor 131 is connected in series with the base. Figure 6 , Figure 6 Schematic diagram of the circuit structure of the vehicle in some embodiments of the present application. Figure 6In the illustrated embodiment, there is a switch device 211 connected to two resistors 131 in series, and then, the controller 210 can connect a resistor 131 to the motor 110. Alternatively, the two resistors 131 in series are connected to the motor 110. Alternatively, a resistor 131 is connected in parallel with the two resistors 131 in series and then connected to the motor 110. Alternatively, the three resistors 131 are short-circuited and then connected to the motor 110, so that the fan 100 can deliver air in 4 different gears. Therefore, the embodiment of the present application can use a switch device 211 connected to one or more resistors 131 to enable the motor 110 of the fan 100 to drive the fan blades 120 in different gears.

[0073] It is understandable that Figure 4 , Figure 5 and Figure 6 All of them are feasible implementation modes provided by the present application. The number of switch devices 211, the number of resistors 131, and the number of resistors 131 that can be connected to the switch devices 211 in the implementation modes of the present application are all contents that can be set according to actual conditions, and can be referred to Figure 4 , Figure 5 and Figure 6 To avoid repetition, no further detailed description is given.

[0074] It can also be understood that, since the gears can be increased by adding resistors 131 and / or switching devices 211, the embodiments of the present application also achieve easy expandability of the gears of the fan 100.

[0075] It is understandable that the closing and opening of the switch device 211 in the controller 210 is set by the controller 210 according to the working condition information, that is, the closing state of the switch device 211 is set by the controller 210 according to the working condition information. The working condition information can be understood as the operating parameters of various components in the vehicle, such as the battery temperature of the power battery and the device temperature of the vehicle controller.

[0076] It can also be understood that the specific process of determining (or setting) the closed state of the switch device 211 according to the working condition information is a content that can be set according to actual conditions. For example, when the battery temperature of the power battery is in the first preset temperature range, the controller 210 can close both the first switch and the second switch and open the third switch so that the fan blades 120 of the fan 100 send out "medium-speed wind". When the battery temperature of the power battery is in the second preset temperature range, the controller 210 can close all the first to third switches so that the fan blades 120 send out "high-speed wind".

[0077] In addition, it should be noted that, since the gear control logic of the embodiment of the present application is relatively simple, the corresponding code can be directly burned or stored in the existing controller (or control chip) of the vehicle to achieve the gear control of the fan 100. In some embodiments, the controller 210 is a domain controller that can be used to control all electronic devices in a certain area (such as a cockpit domain and a power domain, etc.) in the vehicle.

[0078] Furthermore, when the controller 210 is a domain controller, since the computing power of the domain controller is higher than that of a common electronic controller, the gear position of the fan 100 can be determined quickly and accurately.

[0079] In summary, the embodiment of the present application uses the shift module 130 composed of the resistor 131 to enable the gear control of the fan 100 to be realized in a smaller space inside the vehicle. At the same time, because the shift module 130 can be completed in a smaller space inside the vehicle, compared with the scheme of realizing gear control through relays, the embodiment of the present application improves the utilization rate of the space inside the vehicle to a certain extent, and also reduces the difficulty of arranging parts and wiring in the limited vehicle space. In addition, because the relay will emit a certain noise when working, compared with the method of realizing gear control through relays, the embodiment of the present application also reduces the noise during the operation of the fan 100 to a certain extent, thereby improving the user's driving experience.

[0080] Furthermore, compared with the scheme of realizing gear control through stepless variable speed fan 100 and PWM control, the hardware cost of realizing gear control can be controlled because the unit price of resistor 131 and switch device 211 is relatively low. In addition, the gear control logic provided by the embodiment of the present application is relatively simple, and the fan 100 has strong scalability. Furthermore, multiple gears and control logic of multiple gears can be realized at a low hardware cost according to actual needs.

[0081] See also Figure 7 In some embodiments, the shift module 130 also includes a connector 132, which includes at least two groups of pins; one of the at least two switch devices 211 is connected to the motor 110 through one group of the at least two groups of pins, and each of the other switch devices 211 is connected to at least one resistor 131 through one group of the other pins.

[0082] That is, if Figure 7 As shown, the switch device 211 in the embodiment of the present application will be connected through the pins of the connector 132 (i.e. Figure 7 The black semicircle in the figure) is connected to the resistor 131 or the motor 110.

[0083] It can be understood that the connector 132 includes multiple groups of pins, and a group of pins may include two pins. Therefore, a switch device 211 is connected to one of the pins in a group, and a resistor 131 (or multiple resistors 131 connected in series) is connected to another pin in this group, thereby making it possible for the switch device 211 and the resistor 131 to be interconnected simply and efficiently.

[0084] It can also be understood that the motor 110 in the embodiment of the present application can also be connected to the power supply through the pins of the connector 132. However, it can be understood that the motor 110 is connected to the power supply through the pins of the connector 132 is only one feasible way, and the motor 110 can also be connected to the power supply without the pins of the connector 132, that is, Figure 4 , Figure 5 and Figure 6 shown.

[0085] In this way, the embodiment of the present application is based on the setting of the connector 132, so that the switch device 211 and the resistor 131 can be interconnected simply and efficiently.

[0086] In some embodiments, the fan 100 is configured to be connected to the corresponding resistor 131 according to the closing state of the switch device 211 in the controller 210, so that the motor 110 drives the fan blades 120 to rotate at the corresponding gear, wherein the closing state of the switch device 211 is determined by the controller 210 based on the acquired operating condition information and the preset mapping relationship between the operating condition information and the closing state of the switch device 211.

[0087] That is, the controller 210 of the embodiment of the present application pre-stores the mapping relationship between different operating condition information and different gears, or in other words, pre-stores the mapping relationship between different operating condition information and different closing states of the switch device 211.

[0088] by Figure 4 For example, Figure 4The three switch devices 211 in the figure are named as the first switch, the second switch and the third switch from left to right, the two resistors 131 are named as the first resistor 131 and the second resistor 131 from left to right, and the operating condition information includes the battery temperature of the power battery. The preset mapping relationship stored (or recorded) by the controller 210 can be: when the battery temperature is lower than the first temperature (that is, the power battery operates based on a suitable temperature), then the corresponding closed state is "the first to third switches are all disconnected". When the battery temperature is not lower than the first temperature and lower than the second temperature, the corresponding gear is the low speed gear, and then the corresponding closed state is "the first switch is closed, the second switch and the third switch are disconnected". When the battery temperature is not lower than the second temperature and lower than the third temperature, the corresponding gear is the medium speed gear, and the corresponding closed state is "the first switch and the second switch are closed, and the third switch is disconnected". When the battery temperature is not lower than the third temperature, the corresponding gear is the high speed gear, and the corresponding closed state is "the first to the third switches are closed".

[0089] Therefore, when the controller 210 obtains the battery temperature of the power battery (ie, obtains the operating condition information), the closed state of the switch device 211 is determined according to the numerical value of the battery temperature and the above-mentioned mapping relationship.

[0090] Exemplarily, when the battery temperature is not lower than the first temperature and lower than the second temperature, the controller 210 can close the first switch and disconnect the second switch and the third switch according to the above mapping relationship, so that the power supply, the motor 110 and the first resistor 131 form a current loop, and then the motor 110 can drive the fan blades 120 at the "low speed gear", and the fan blades 120 deliver "low speed wind".

[0091] In addition, it can also be understood that the above-mentioned preset mapping relationship in the implementation manner of the present application can be set according to actual conditions, and the above-mentioned mapping relationship between the power battery and the closed state is only an example.

[0092] In this way, the embodiment of the present application is based on the preset mapping relationship between the operating condition information and the closing state of the switch device 211, so that the controller 210 can quickly determine or set the corresponding closing state of the switch device 211 after obtaining the operating condition information, so that the motor 110 can drive the fan blades 120 at an appropriate gear, thereby ensuring the efficient execution of the fan 100.

[0093] In certain embodiments, the controller 210 includes a front body domain controller;

[0094] The fan 100 is configured to be connected to the corresponding resistor 131 according to the closing state of the switch device 211 in the controller 210, so that the motor 110 drives the fan blades 120 to rotate at the corresponding gear position, wherein the closing state of the switch device 211 is determined by the front body domain controller based on the acquired gear shifting demand and the current closing state of the switch device 211, and the gear shifting demand is determined based on the operating condition information.

[0095] That is, the operating condition information in the implementation mode of the present application can be used to determine whether there is a gear shifting requirement for the components in the vehicle, that is, whether the fan 100 needs to be switched from the current gear to another gear. Furthermore, when the gear shifting requirement is determined based on the operating condition information, the current closed state of the switch device 211 is adjusted according to the current gear of the fan 100 and the gear shifting requirement, that is, according to the current closed state of the switch device 211 and the gear shifting requirement, so that the gear of the fan 100 is changed.

[0096] It can be understood that the specific process of determining the gear shift requirement based on the operating condition information is a content that can be set according to actual conditions, and the specific process of determining (or changing) the closing state of the switch device 211 based on the gear shift requirement and the current closing state of the switch device 211 is also a content that can be set according to actual conditions.

[0097] For example, when the operating condition information includes the battery temperature of the power battery, and the motor 110 has driven the fan blades 120 at a "low gear", if the front body domain controller obtains the battery temperature of the power battery and determines that the battery temperature of the power battery exceeds the preset threshold, it is determined that the heat dissipation of the power battery is insufficient, or that there is a need for heat dissipation. At the same time, because the motor 110 has driven the fan blades 120 at a low gear, the front body domain controller can, based on the current closed state of the switch device 211, for example, the first switch is closed and the second and third switches are disconnected (corresponding to Figure 4 ), the current closed state of the switch device 211 is adjusted, such as adjusting "the first switch is closed, the second switch and the third switch are opened" to "the first switch and the second switch are closed, and the third switch is opened", so that the motor 110 drives the fan blades 120 at the "medium speed gear".

[0098] Further, if the motor 110 switches from the "low speed gear" to the "medium speed gear" for a certain period of time, the front body domain controller obtains the battery temperature of the power battery and determines that the battery temperature of the power battery exceeds the preset threshold, then it is determined that the heat dissipation of the power battery is insufficient. In other words, the power battery still has a heat dissipation demand. The controller 210 can, based on the current closed state of the switch device 211, that is, based on "the first switch and the second switch are both closed, and the third switch is open", set the state of the first to third switches to "the first to third switches are all closed", so that the motor 110 drives the fan blades 120 in the "high speed gear".

[0099] Optionally, if the front body domain controller fails to determine the gear shifting requirement information based on the acquired working condition information, such as the battery temperature of the power battery does not exceed the preset threshold, it means that the temperature of the power battery has dropped to a suitable working temperature, or in other words, the heat dissipation effect of the power battery is appropriate. Then, the front body domain controller can control the gear position of the fan 100 to remain unchanged, or to decrease, such as switching from "the first to the third switches are all closed" to "the first switch is closed, the second switch and the third switch are both disconnected", or "the first switch is closed, the second switch and the third switch are disconnected", or "the first to the third switches are all disconnected".

[0100] And, it should be noted that the implementation method of the present application is to achieve vehicle control based on a domain controller.

[0101] Further, it can be understood that the implementation method of the present application is to complete the vehicle settings based on the electronic and electrical architecture of the domain control. It can also be understood that compared with the general electronic control unit (ECU), the domain controller has higher computing power and can complete digital processing or logic control with higher efficiency or speed. Therefore, in the implementation method of the present application, the gear position of the fan 100 is realized according to the front body domain controller. When the front body domain controller obtains the gear shifting requirement, it can quickly perform the corresponding gear shifting operation, that is, quickly adjust the closed state of the switch device 211, thereby realizing the timely gear adjustment of the fan 100, and can quickly respond to the gear shifting requirement triggered by insufficient heat dissipation.

[0102] In this way, the embodiment of the present application enables the front body domain controller to quickly adjust the gear of the fan 100 based on the determination of the gear shifting demand, that is, to adjust the current closed state of the switch device 211, so that the gear switching of the fan 100 can be carried out efficiently. At the same time, because the embodiment of the present application is based on the front body domain controller with higher computing power than the electronic control unit to realize the gear control of the fan, it can ensure to a certain extent that the fan 100 can change the gear in a timely or reliable manner, and the heat dissipation effect in the car is improved to a certain extent.

[0103] In certain embodiments, the shift demand is determined by the vehicle's power domain controller based on one or more combinations of collected drive motor temperature, electronic control temperature, and vehicle controller temperature, and / or by the vehicle's right body domain controller based on one or more combinations of collected vehicle battery power, vehicle air conditioning line pressure, and battery thermal management system line pressure.

[0104] To more clearly illustrate the implementation of this application, please refer to Figure 8 , Figure 8Schematic diagram of the fan in some embodiments of the present application. That is, the vehicle of the embodiment of the present application includes a front body domain controller 212 (corresponding to the controller 210), a right body domain controller 220 and a power domain controller 230. Furthermore, the right body domain controller 220 and the power domain controller 230 are used to obtain operating condition information and determine the shifting requirement information based on the operating condition information. After the right body domain controller 220 and / or the power domain controller 230 determine the shifting requirement information, the shifting requirement information is sent to the front body domain controller 212, and the front body domain controller 212 adjusts the current closed state of the switch device according to the shifting requirement information, thereby completing the shifting control of the fan 100.

[0105] It is understandable that due to the layout of the components in the vehicle, the domain controller of the vehicle is usually responsible for the control and management of the components that are closer to itself. Therefore, the power domain controller 230 of the embodiment of the present application can collect and determine whether the components in the vehicle (including but not limited to the drive motor, electronic control and vehicle controller) are working at an appropriate temperature based on the drive motor temperature, electronic control temperature and vehicle controller temperature, and then determine whether the fan needs to be shifted.

[0106] Similarly, the right body domain controller 220 can collect and determine whether the fan has been degraded based on the vehicle battery power, vehicle air conditioning pipeline pressure and battery thermal management system pipeline pressure, and then determine whether the fan needs to be shifted.

[0107] In this way, the implementation method of the present application enables the power domain controller 230 to determine that the fan needs to adjust the gear according to one or more combinations of the collected drive motor temperature, electronic control temperature and vehicle controller temperature, or the right body domain controller 220 determines that the fan needs to adjust the gear according to one or more combinations of the collected vehicle battery power, vehicle air conditioning pipeline pressure and battery thermal management system pipeline pressure. That is, the power domain controller 230 or the right body domain controller 220 determines that the fan gear needs to be changed based on the collected information, that is, when there is a gear shift requirement, the body domain controller can change the fan gear accordingly, so that the fan gear can be reasonably adjusted. At the same time, because the implementation method of the present application determines the fan gear shift requirement based on the power domain controller 230 and the right body domain controller 220, or in other words, the determination of the gear shift requirement is determined by a device with a higher computing power than the electronic control unit, the credibility of the gear shift requirement can be guaranteed to a certain extent.

[0108] In some embodiments, the switch device 211 is a metal oxide semiconductor field effect transistor.

[0109] It should be noted that, compared with fuses and relays, MOS tubes (Metal Oxide Semiconductor Field-Effect Transistor) have the ability of self-protection and automatic recovery. Compared with relays, they are more reliable, have a longer life, and require less space for installation.

[0110] Thus, the switching device 211 composed of the metal oxide semiconductor field effect transistor in the embodiment of the present application can further reduce the space inside the vehicle required to achieve the gear control of the fan 100, thereby further reducing the difficulty of arranging components and wiring in the limited vehicle space.

[0111] The embodiment of the present application further provides a vehicle, the vehicle comprising a vehicle body and the above-mentioned fan 100. The fan 100 is mounted on the vehicle body.

[0112] See also Fig. 9 The embodiment of the present application provides a method for controlling a vehicle fan, wherein the vehicle includes the above-mentioned fan 100, and the method includes:

[0113] 01: Get working condition information;

[0114] 02: Determine the closing state of the switch device according to the working condition information to control the fan motor to drive the fan blades to rotate at the corresponding gear.

[0115] The embodiment of the present application also provides a control module for a vehicle fan, and the vehicle includes the above-mentioned fan 100. The control method of the vehicle fan in the embodiment of the present application can be implemented by the control module of the vehicle fan in the embodiment of the present application. Specifically, the control module of the vehicle fan includes a transceiver unit and a processing unit. Among them, the transceiver unit is used to obtain working condition information. The processing unit is used to determine the closed state of the switch device 211 according to the working condition information, so as to control the motor 110 of the fan 100 to drive the fan blades 120 to rotate at the corresponding gear.

[0116] The embodiment of the present application also provides a vehicle. The control method of the vehicle fan in the embodiment of the present application can be implemented by the vehicle in the embodiment of the present application. Specifically, a computer program is stored in the memory, and the processor is used to obtain working condition information, and to determine the closed state of the switch device 211 according to the working condition information, so as to control the motor 110 of the fan 100 to drive the fan blades 120 to rotate at the corresponding gear.

[0117] That is, after the controller 210 of the embodiment of the present application is connected to the above-mentioned fan 100, it can set the closing state of each switching device according to the operating condition information obtained by itself, so that the motor 110 in the fan 100 can establish or disconnect the connection with the resistor 131 in the shift module 130 through the closed or open switch device 211, thereby driving the fan blades 120 to rotate at the corresponding gear position.

[0118] In this way, the controller 210 of the embodiment of the present application enables the gear control of the fan 100 to be realized in a smaller space inside the vehicle through the gear shift module 130 composed of the resistor 131. At the same time, because the gear shift module 130 can be completed in a smaller space inside the vehicle, compared with the scheme of realizing gear control through relays, the embodiment of the present application improves the utilization rate of the space inside the vehicle to a certain extent, and also reduces the difficulty of arranging parts and wiring in the limited vehicle space. In addition, because the relay will emit a certain noise when working, compared with the method of realizing gear control through relays, the embodiment of the present application also reduces the noise during the operation of the fan 100 to a certain extent, thereby improving the user's driving experience.

[0119] In some embodiments, step 02 includes:

[0120] According to the operating condition information and the preset mapping relationship between the operating condition information and the closing state of the switch device 211, the closing state of the switch device 211 is determined to control the motor 110 of the fan 100 to drive the fan blades to rotate at the corresponding gear.

[0121] The processing unit of the embodiment of the present application is also used to determine the closing state of the switch device 211 based on the operating condition information and the preset mapping relationship between the operating condition information and the closing state of the switch device 211, so as to control the motor 110 of the fan 100 to drive the fan blades to rotate at the corresponding gear.

[0122] The processor of the embodiment of the present application is also used to determine the closing state of the switch device 211 based on the operating condition information and the preset mapping relationship between the operating condition information and the closing state of the switch device 211, so as to control the motor 110 of the fan 100 to drive the fan blades to rotate at the corresponding gear.

[0123] That is, the controller 210 in the embodiment of the present application can determine the closing state of the switch device 211 corresponding to the operating condition information (or the gear position corresponding to the operating condition information) based on its own pre-stored mapping relationship data (or the preset mapping relationship) after obtaining the operating condition information according to the mapping relationship data, and then control each switch device 211 to be closed or opened, so that the motor 110 establishes or disconnects the connection with the resistor 131, thereby driving the fan blades to rotate at the corresponding gear position.

[0124] In this way, the embodiment of the present application is based on the preset mapping relationship between the operating condition information and the closing state of the switch device 211, so that the controller 210 can quickly determine or set the corresponding closing state of the switch device 211 after obtaining the operating condition information, so that the motor 110 can drive the fan blades 120 at an appropriate gear, thereby ensuring efficient execution of heat dissipation in the vehicle.

[0125] In some embodiments, step 02 includes:

[0126] According to the acquired gear shifting demand and the current closed state of the switch device 211, the closed state of the switch device 211 is determined to control the motor 110 of the fan 100 to drive the fan blades to rotate at the corresponding gear.

[0127] The processing unit of the embodiment of the present application is also used to determine the closing state of the switch device 211 according to the acquired gear shifting demand and the current closing state of the switch device 211, so as to control the motor 110 of the fan 100 to drive the fan blades to rotate at the corresponding gear.

[0128] The processor of the embodiment of the present application is also used to determine the closing state of the switch device 211 according to the acquired gear shifting demand and the current closing state of the switch device 211, so as to control the motor 110 of the fan 100 to drive the fan blades to rotate at the corresponding gear.

[0129] That is, after obtaining the working condition information, the controller 210 of the embodiment of the present application can determine whether the current heat dissipation demand of the components in the vehicle is met, or whether the gear shifting demand information can be determined based on the working condition information. If it can, it means that the current heat dissipation demand is not met, and the fan gear may need to be increased. Therefore, the controller 210 determines or sets the closed state of the switch device 211 according to the gear shifting demand and the current closed state of the switch device 211.

[0130] Exemplarily, when the operating condition information includes the battery temperature of the power battery and the motor 110 has driven the fan blades 120 at a "low gear", if the controller 210 obtains the battery temperature of the power battery and determines that the battery temperature of the power battery exceeds the preset threshold, it is determined that the heat dissipation of the power battery is insufficient, in other words, there is a heat dissipation demand. At the same time, because the motor 110 has driven the fan blades 120 at a low gear, the controller 210 can, based on the current closed state of the switch device 211, for example, the first switch is closed and the second and third switches are disconnected (corresponding to Figure 4 ), the current closed state of the switch device 211 is adjusted, such as adjusting "the first switch is closed, the second switch and the third switch are opened" to "the first switch and the second switch are closed, and the third switch is opened", so that the motor 110 drives the fan blades 120 at the "medium speed gear".

[0131] In this way, the embodiment of the present application enables the controller 210 to quickly adjust the gear of the fan 100 based on the determination of the gear shifting requirement, that is, to adjust the current closed state of the switch device 211, so that the gear switching of the fan 100 can be carried out efficiently.

[0132] Optionally, the controller 210 determines the closing state of the closing device according to the gear shifting requirement information and the current closing state, wherein the gear shifting requirement information is Figure 8 The first secondary controller 220 and the second secondary controller 230 in the fan 100 are determined, and the gear control of the fan 100 can be performed as follows Figure 4 or Figure 5 In the implementation mode of the circuit shown, the gear control logic of the fan 100 in the implementation mode of the present application can be shown in Figure 9.

[0133] Specifically, when the first secondary controller 220 determines, based on the acquired air-conditioning pipeline pressure and the battery thermal management system pipeline pressure, that when the fan 100100 is running at the current gear, the heat dissipation of the air-conditioning or the battery thermal management system is not met (such as the air-conditioning pipeline pressure or the battery thermal management system pipeline pressure exceeds the preset pressure value), the first secondary controller 220 may generate gear shifting demand information.

[0134] Similarly, the second secondary controller 230 determines, based on the acquired motor temperature and electronic control temperature, or the acquired temperature of the vehicle controller, or the acquired battery level of the vehicle, that when the fan 100 is running at the current gear, the heat dissipation requirements of any of the components in the motor, electronic control and vehicle controller in the vehicle are not met, then the second secondary controller 230 may generate a gear shift requirement.

[0135] The first secondary controller 220 and / or the second secondary controller 230 generates the gear shifting request information and sends the gear shifting request information to the controller 210 .

[0136] When the controller 210 receives the gear shifting request information, the gear of the fan 100 can be controlled to increase. For example, when the motor 110 drives the blades 120 in "neutral gear" (corresponding to the first to third switches being disconnected), the motor 110 can be controlled to drive the blades 120 in "low gear" (corresponding to the first switch being closed, and the second and third switches being disconnected). Alternatively, when the motor 110 drives the blades 120 in "low gear", the motor 110 is controlled to drive the blades 120 in "medium gear" (corresponding to the first and second switches being closed, and the third switch being disconnected). Alternatively, when the motor 110 drives the blades 120 in "medium gear", the motor 110 is controlled to drive the blades 120 in "high gear" (corresponding to the first to third switches being closed).

[0137] In some embodiments, when the second secondary controller 230 obtains the battery power of the vehicle and knows that the battery power is not higher than 10%, it will generate special gear shifting requirement information. After receiving the gear shifting requirement information, the controller 210 will control the gear of the fan 100 to decrease by one level. For example, when the motor 110 drives the fan blades 120 at a "high gear", if the controller 210 receives the gear shifting requirement information corresponding to the battery power, the motor 110 can be controlled to drive the fan blades 120 at a "medium gear".

[0138] Alternatively, the gear of the fan 100 is controlled to be adjusted to a preset gear (such as "neutral" or "low speed"). If the motor 110 drives the fan blades 120 at "high speed", if the controller 210 receives the gear shifting request information corresponding to the power level, the motor 110 can be controlled to drive the fan blades 120 at "low speed".

[0139] In addition, it can be understood that the control method of the automobile fan in the embodiment of the present application can be understood as the steps that can be executed by the controller 110 in the fan 100.

[0140] The embodiment of the present application further provides a vehicle, comprising a vehicle body and the above-mentioned vehicle fan control module. The vehicle fan control module is installed on the vehicle body.

[0141] The embodiment of the present application further provides a computer-readable storage medium containing a computer program. When the computer program is executed by one or more processors, the one or more processors execute the control method of the vehicle fan 100 of the present application.
