Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a control method and device of an active grille shutter, a storage medium and a vehicle. BACKGROUND

[0002] An active grille shutter (AGS) is an air intake grille that can adjust the opening degree, and can adjust the opening or closing state of the active grille shutter according to the vehicle speed and indoor temperature.

[0003] In the prior art, after the vehicle is started, the active grille shutter can adjust the opening degree according to the temperature of the engine, so as to achieve the effect of quickly warming up the engine and make the engine enter the working state in a short time. In addition, during high-speed driving, the active grille shutter is always in an open state, which will increase the wind resistance and increase fuel consumption. If the active grille shutter is closed in time, it will bring lower wind resistance coefficient to the vehicle, thereby improving the stability and fuel economy of the vehicle.

[0004] However, in the case of the whole vehicle being powered off, the user wants to close or open the active grille shutter in the current scene, for example: in winter, the user parks the vehicle outdoors in cold weather and wants to close the active grille shutter to keep the engine warm; or in summer, the user parks the vehicle outdoors in hot weather and wants to open the active grille shutter to cool the vehicle.

[0074] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0075] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0076] The following detailed description, in conjunction with the accompanying drawings, of a control method, device, storage medium, and vehicle for an active air intake grille provided in this application, through specific embodiments and application scenarios, will be provided in detail.

[0077] The first embodiment of the present invention relates to a control method for an active air intake grille, applied to an engine control module (ECM), the flowchart of which is shown below. Figure 1 As shown, it includes:

[0078] Step 101: Obtain the current vehicle power mode.

[0079] It should be noted that, in this embodiment of the invention, the Engine Control Module (ECM) needs to first obtain the current vehicle power mode, which includes power-on mode or power-off mode.

[0080] Step 102: When the vehicle power mode is in power-off mode, obtain the vehicle configuration information, which includes first configuration information and second configuration information. The first configuration information is used to indicate that the vehicle is a high-end model, and the second configuration information is used to indicate that the vehicle is a low-end model.

[0081] It should be noted that, in this embodiment of the invention, when the vehicle's power mode is in power-off mode, the Engine Control Module (ECM) acquires the current vehicle configuration information, which includes first configuration information and second configuration information. For ease of understanding by those skilled in the art, the first configuration information refers to the current vehicle being a high-spec model, and the second configuration information refers to the current vehicle being a low-spec model.

[0082] Furthermore, such as Figure 2 As shown, step 101 also includes the following steps:

[0083] Step 201: When the vehicle power mode is in power-on mode, obtain the current fan duty cycle information, engine coolant temperature sensor fault information, and fan fault information.

[0084] It should be noted that, in this embodiment of the invention, when the vehicle power mode is the power-on mode, the vehicle unit (HeadUnit, HUT) obtains the fan duty cycle information through the fan control unit and obtains the engine coolant temperature sensor fault information and fan fault information through the instrument panel. The engine coolant temperature sensor fault information includes engine coolant temperature sensor failure or engine coolant temperature sensor not failure, and the fan fault information includes fan failure or fan not failure.

[0085] Step 202: Determine whether the fan duty cycle information is greater than or equal to the preset first threshold, whether the engine coolant temperature sensor fault information meets the preset second target condition, and whether the fan fault information meets the preset third target condition.

[0086] It should be noted that, in this embodiment of the invention, the preset first threshold is 50%, the preset second target condition is an engine coolant temperature sensor malfunction, and the preset third target condition is a fan malfunction. The Engine Control Module (ECM) determines whether the fan duty cycle is greater than or equal to 50% based on the acquired fan duty cycle information; determines whether the engine coolant temperature sensor is malfunctioning based on the acquired engine coolant temperature sensor malfunction information; and determines whether the fan is malfunctioning based on the acquired fan malfunction information.

[0087] Step 203: If the fan duty cycle information is greater than or equal to the preset first threshold, or the engine coolant temperature sensor fault information meets the preset second target condition, or the fan fault information meets the preset third target condition, then control the active air intake grille to adjust to the second target opening value.

[0088] It should be noted that, in this embodiment of the invention, the second target opening value is 0. When the fan duty cycle is greater than or equal to 50%, the Engine Control Module (ECM) adjusts the opening value of the active air intake grille to 0, meaning the active air intake grille is fully open; or when the engine coolant temperature sensor is faulty, the Engine Control Module (ECM) adjusts the opening value of the active air intake grille to 0, meaning the active air intake grille is fully open; or when the fan is faulty, the Engine Control Module (ECM) adjusts the opening value of the active air intake grille to 0, meaning the active air intake grille is fully open.

[0089] Furthermore, such as Figure 3 As shown, step 202 also includes the following steps:

[0090] Step 301: Obtain current vehicle speed information, ambient temperature information, engine intake air temperature information, engine coolant temperature information, air conditioning pressure information, transmission oil temperature information, and hybrid vehicle control unit (HCU) information.

[0091] It should be noted that, in this embodiment of the invention, when the vehicle power mode is power-on mode, the vehicle unit (HUT) obtains the current vehicle speed information through the Electronic Stability Program (ESP), the current ambient temperature information through the air conditioner (AC) module, the engine intake air temperature information through the engine intake air temperature sensor, the engine coolant temperature information through the engine coolant temperature sensor, the air conditioner pressure information through the air conditioner (AC) module, the transmission oil temperature information through the transmission oil temperature sensor, and the hybrid vehicle control unit (HCU) information through the hybrid vehicle control unit (HCU).

[0092] Step 302: If the fan duty cycle information is less than the preset first threshold, the engine coolant temperature sensor fault information does not meet the preset second target condition, and the fan fault information does not meet the preset third target condition, then the third target opening value corresponding to the vehicle speed information and ambient temperature information, the fourth target opening value corresponding to the engine intake air temperature information and engine coolant temperature information, the fifth target opening value corresponding to the air conditioning pressure information, the sixth target opening value corresponding to the transmission oil temperature information, and the seventh target opening value corresponding to the hybrid vehicle controller HCU information are obtained respectively.

[0093] It should be noted that, in this embodiment of the invention, when the fan duty cycle is less than 50%, the engine coolant temperature sensor is not faulty, and the fan is not faulty, the Engine Control Module (ECM) acquires the third target opening value corresponding to the current vehicle speed and ambient temperature information, the fourth target opening value corresponding to the current engine intake air temperature and engine coolant temperature information, the fifth target opening value corresponding to the current air conditioning pressure information, the sixth target opening value corresponding to the current transmission oil temperature information, and the seventh target opening value corresponding to the current hybrid vehicle control unit (HCU) information.

[0094] Step 303: Determine the largest target opening value among the third, fourth, fifth, sixth, and seventh target opening values ​​as the final target opening value.

[0095] It should be noted that, in this embodiment of the invention, after the Engine Control Module (ECM) obtains the third, fourth, fifth, sixth, and seventh target opening values, it compares the five data values ​​and selects the target opening value with the largest value as the final target opening value.

[0096] Step 304: Control the active air intake grille to adjust to the final target opening value.

[0097] It should be noted that, in this embodiment of the invention, the Engine Control Module (ECM) adjusts the opening value of the active air intake grille so that its opening value is the final target opening value.

[0098] Further, in this embodiment of the invention, step 302, which involves obtaining the third target opening value corresponding to vehicle speed information and ambient temperature information, the fourth target opening value corresponding to engine intake air temperature information and engine coolant temperature information, the fifth target opening value corresponding to air conditioning pressure information, the sixth target opening value corresponding to transmission oil temperature information, and the seventh target opening value corresponding to hybrid vehicle controller (HCU) information, specifically includes the following steps: obtaining the third target opening value from a pre-stored relationship table between vehicle speed information, ambient temperature information, and active grille opening value based on vehicle speed information and ambient temperature information; and obtaining the third target opening value from a pre-stored relationship table between engine intake air temperature information and engine coolant temperature information based on engine intake air temperature information and engine coolant temperature information. The system obtains the fourth target opening value from a table showing the relationship between engine coolant temperature information and active grille opening value; and obtains the fifth target opening value from a pre-stored table showing the relationship between air conditioning pressure information and active grille opening value based on air conditioning pressure information; and obtains the sixth target opening value from a pre-stored table showing the relationship between transmission oil temperature information and active grille opening value based on transmission oil temperature information; and obtains the seventh target opening value from the information provided by the hybrid vehicle controller (HCU). The HCU information is obtained by processing the active grille opening value request information sent by the control unit. The control unit includes the battery, battery pack, and motor.

[0099] It should be noted that, in this embodiment of the invention, as shown in Table 1, Table 1 is a table relating vehicle speed information, ambient temperature information, and active grille shutter opening value. After obtaining the current vehicle speed and the current ambient temperature information, the Engine Control Module (ECM) can obtain the active grille shutter opening value corresponding to the current vehicle speed and the current ambient temperature information, i.e., the third target opening value, from the pre-stored table relating vehicle speed information, ambient temperature information, and active grille shutter opening value. For example, if the current vehicle speed is 60 and the current ambient temperature is 15, the active grille opening value corresponding to the current vehicle speed of 60 and the current ambient temperature of 15 can be found in Table 1, which is the third target opening value of 100; if the current vehicle speed is 90 and the current ambient temperature is 30, the active grille opening value corresponding to the current vehicle speed of 90 and the current ambient temperature of 30 can be found in Table 1, which is the third target opening value of 33.

[0100] Table 1. Relationship between vehicle speed information, ambient temperature information, and active grille shutter opening value.

[0101]

[0102] As shown in Table 2, Table 2 is a table showing the relationship between engine intake air temperature information, engine coolant temperature information, and active grille shutter opening value. After obtaining the current vehicle's engine intake air temperature information and engine coolant temperature information, the Engine Control Module (ECM) can retrieve the corresponding active grille shutter opening value, i.e., the fourth target opening value, from the pre-stored table showing the relationship between engine intake air temperature information, engine coolant temperature information, and active grille shutter opening value. For example: If the current engine intake temperature of the vehicle is 20°C and the current engine coolant temperature is 93°C, the active grille opening value corresponding to the current engine intake temperature of 20°C and the current engine coolant temperature of 93°C can be found in Table 2, which is the fourth target opening value of 100; if the current engine intake temperature of the vehicle is 40°C and the current engine coolant temperature is 90°C, the active grille opening value corresponding to the current engine intake temperature of 40°C and the current engine coolant temperature of 90°C can be found in Table 2, which is the fourth target opening value of 33.

[0103] Table 2. Relationship between Engine Intake Air Temperature Information, Engine Coolant Temperature Information, and Active Grille Opening Value

[0104]

[0105] As shown in Table 3, this table displays the relationship between air conditioning pressure information and the active grille shutter opening value. After obtaining the current vehicle's air conditioning pressure information, the Engine Control Module (ECM) can retrieve the corresponding active grille shutter opening value, i.e., the fifth target opening value, from the pre-stored table of the relationship between air conditioning pressure information and active grille shutter opening value. For example, when the current vehicle's air conditioning pressure is less than or equal to 1, the corresponding active grille shutter opening value, i.e., the fifth target opening value, can be found in Table 3.

[0107] Air conditioner pressure information Mpa P≤1 1< P Active intake grille opening 100 33 0

[0108] As shown in Table 4, this table represents the relationship between transmission fluid temperature information and the active grille shutter opening value. After obtaining the current transmission fluid temperature information of the vehicle, the Engine Control Module (ECM) can retrieve the corresponding active grille shutter opening value, also known as the sixth target opening value, from the pre-stored table. For example, when the current transmission fluid temperature is below 75°C, the corresponding active grille shutter opening value, or the sixth target opening value, can be found in Table 4.

[0111] The control units controlled by the Hybrid Control Unit (HCU) include, but are not limited to, the battery, battery pack, and motor. When the battery, battery pack, or motor needs the active grille to open or close, it can send active grille request information to the Hybrid Control Unit (HCU). When the Hybrid Control Unit (HCU) receives active grille shutter request information from the battery, battery pack, or motor, it can process this request information to generate Hybrid Control Unit (HCU) information corresponding to the active grille shutter request information sent by the battery, battery pack, or motor. That is, it can calculate and process the request information to generate the desired opening value of the active grille shutter. After obtaining the Hybrid Control Unit (HCU) information, it sends the Hybrid Control Unit (HCU) information to the Engine Control Module (ECM) via the Powertrain CAN bus (PowerTrain CAN, PT CAN). The Engine Control Module (ECM) can directly determine the seventh target opening value based on the Hybrid Control Unit (HCU) information.

[0112] Step 103: When the vehicle configuration information is the first configuration information, obtain the current parameter information of the vehicle, including the fault information of the active grille shutter, the engine coolant temperature information, and the transmission oil temperature information.

[0113] It should be noted that, in this embodiment of the invention, when the current vehicle configuration information is a high-end model, the current parameter information of the vehicle is obtained. This current parameter information includes, but is not limited to, fault information of the active grille shutter, engine coolant temperature information, and transmission oil temperature information. Specifically, the Engine Control Module (ECM) obtains the current fault information of the active grille shutter through the instrument panel. This fault information includes whether the active grille shutter is faulty or not. The ECM obtains the current engine coolant temperature information through the engine intake air temperature sensor and the current transmission oil temperature information through the transmission oil temperature sensor. After the Engine Control Module (ECM) obtains the vehicle's current parameter information, it generates an optimal active grille shutter opening value based on this information and sends it to the HeadUnit (HUT). Upon receiving this optimal value from the ECM, the HeadUnit displays it. If the user selects the optimal active grille shutter opening value recommended by the HeadUnit, the ECM adjusts the grille shutter opening to the optimal value. If the user does not select the recommended value, step 104 continues. This invention recommends the optimal active grille shutter opening value to the user through the vehicle's infotainment system. It provides the user with prompts and options, preventing users from being unsure how to set the active grille shutter opening value and improving the user experience of using the active grille shutter control function.

[0114] Step 104: When the active air intake grille opening value information is received from the vehicle HUT, determine whether the active air intake grille fault information, engine coolant temperature information, and transmission oil temperature information meet the preset first target condition.

[0115] It should be noted that in this embodiment of the invention, the term "HeadUnit" (HUT) refers to an in-vehicle infotainment product installed in a car. Currently, in addition to traditional functions such as radio, music and video playback, and navigation, headunits now include 3G and Telematics capabilities. Combined with the car's CAN-BUS technology, they enable communication between people and the vehicle, and between the vehicle and the outside world, enhancing user experience and providing services and safety-related functions. Among these functions, "I-Call" and "E-Call" are the most typical examples. Furthermore, the preset first target conditions are: no active grille shutter malfunction, engine coolant temperature below 110°C (TBD), and transmission oil temperature below 100°C. Users can independently select the opening value of the active grille shutter on the vehicle's HeadUnit (HUT). Specifically, users can select the opening value of the active grille shutter from multiple control levels (e.g., 0, 33, 66, 100) on the HeadUnit (HUT). Users can also perform stepless speed adjustment on the HeadUnit (HUT), meaning they can select any opening value between 0 and 100. After the user completes the selection of the active grille shutter opening value, the HeadUnit (HUT) will generate the active grille shutter opening value information and send it to the Engine Control Module (ECM). When the Engine Control Module (ECM) receives the active grille shutter opening value information from the HeadUnit (HUT), it determines whether the active grille shutter fault information is not a fault, whether the engine coolant temperature is less than 110°C (TBD), and whether the transmission oil temperature is less than 100°C based on the acquired active grille shutter fault information, engine coolant temperature information, and transmission oil temperature information.

[0116] Step 105: If satisfied, control the active air intake grille to adjust to the first target opening value based on the active air intake grille opening value information.

[0117] It should be noted that, in this embodiment of the invention, when the Engine Control Module (ECM) determines that the active air intake grille is not faulty, the engine coolant temperature is less than 110°C (TBD), and the transmission oil temperature is less than 100°C, the Engine Control Module (ECM) adjusts the opening value of the active air intake grille to the first target opening value based on the active air intake grille opening value information sent by the Head Unit (HUT).

[0118] This invention provides a control method for an active air intake grille. When the vehicle's power mode is off and the vehicle is a high-spec model, the user can independently select the opening value of the active air intake grille to achieve the vehicle's heat preservation or heat dissipation functions. This achieves intelligent control of the active air intake grille opening value for high-spec models, further meeting user needs and improving the user experience. This invention applies different active air intake grille opening value control strategies for different vehicle configurations, enabling intelligent control of the active air intake grille opening value for vehicles of different configurations even when the vehicle's power mode is off. This improves the intelligence of the active air intake grille control while meeting the needs of different users. When the vehicle's power mode is on, this invention can obtain the corresponding active air intake grille opening value based on different detected information, and finally use the maximum active air intake grille opening value as the final target opening value, achieving intelligent control of the active air intake grille opening value even when the vehicle is powered on. This invention obtains the active air intake grille opening value corresponding to different detected information by pre-stored vehicle relationship table, realizing that the active air intake grille opening value can be obtained directly from the relationship table, improving the efficiency of obtaining the active air intake grille opening value, and thus achieving the technical effect of improving the efficiency of controlling the active air intake grille opening value.

[0119] The second embodiment of the present invention relates to a control method for an active air intake grille, applied to an engine control module (ECM), the flowchart of which is shown below. Figure 4 As shown, it includes:

[0120] Step 401: Obtain the current vehicle power mode.

[0121] Step 402: When the vehicle power mode is in power-off mode, obtain the vehicle configuration information, which includes first configuration information and second configuration information. The first configuration information is used to indicate that the vehicle is a high-end model, and the second configuration information is used to indicate that the vehicle is a low-end model.

[0122] It should be noted that, in the embodiments of the present invention, since the above steps are the same as those of steps 101 and 102, the discussion of steps 401 and 402 can refer to the discussion of steps 101 and 102, and will not be repeated here.

[0123] Step 403: When the vehicle's configuration information is the second configuration information, obtain the ambient temperature information.

[0124] It should be noted that, in this embodiment of the invention, when the current vehicle configuration information is a low-end model, the Engine Control Module (ECM) further obtains the ambient temperature information of the current environment of the vehicle through the Air Condition Control Module (AC).

[0125] Step 404: When the ambient temperature information meets the preset fourth target condition, control the active air intake grille to adjust to the eighth target opening value.

[0126] It should be noted that in this embodiment of the invention, the preset fourth target condition is an ambient temperature greater than or equal to 0°C, and the eighth target opening value is 0. The Engine Control Module (ECM) determines whether the ambient temperature of the vehicle's current environment is greater than or equal to 0°C based on the acquired ambient temperature information. If the ambient temperature of the vehicle's current environment is greater than or equal to 0°C, the Engine Control Module (ECM) adjusts the opening value of the active grille to 0, that is, the active grille is fully open. Figure 9 As shown, 1 represents the blade shaft of the active air intake grille, and the angle of the active air intake grille can be continuously and arbitrarily changed between 0° and 90°. When the angle of the active air intake grille is 0°, the corresponding opening value of the active air intake grille is 0, indicating that the active air intake grille is fully open; when the angle of the active air intake grille is 90°, the corresponding opening value of the active air intake grille is 100, indicating that the active air intake grille is fully closed.

[0127] Step 405: When the ambient temperature information does not meet the preset fourth target condition, control the active air intake grille to adjust to the ninth target opening value.

[0128] It should be noted that, in this embodiment of the invention, the preset fourth target condition is an ambient temperature less than 0°C, and the ninth target opening value is 100. When the Engine Control Module (ECM) determines that the ambient temperature of the vehicle's current environment is less than 0°C, the ECM adjusts the opening value of the active grille to 100, that is, the active grille is completely closed.

[0129] Furthermore, in this embodiment of the invention, step 401 further includes: when the vehicle power mode is in power-on mode, acquiring the current fan duty cycle information, engine coolant temperature sensor fault information, and fan fault information; determining whether the fan duty cycle information is greater than or equal to a preset first threshold, whether the engine coolant temperature sensor fault information meets a preset second target condition, and whether the fan fault information meets a preset third target condition; if the fan duty cycle information is greater than or equal to the preset first threshold, or the engine coolant temperature sensor fault information meets the preset second target condition, or the fan fault information meets the preset third target condition, then controlling the active air intake grille to adjust to the second target opening value.

[0130] It should be noted that, in the embodiments of the present invention, since the above steps are the same as the steps 201-203, the discussion of the above steps can refer to the discussion of steps 201-203, and will not be repeated here.

[0131] Furthermore, in this embodiment of the invention, determining whether the fan duty cycle information is greater than or equal to a preset first threshold, whether the engine coolant temperature sensor fault information meets a preset second target condition, and whether the fan fault information meets a preset third target condition further includes: acquiring current vehicle speed information, ambient temperature information, engine intake air temperature information, engine coolant temperature information, air conditioning pressure information, transmission oil temperature information, and hybrid vehicle controller (HCU) information; if the fan duty cycle information is less than the preset first threshold, the engine coolant temperature sensor fault information does not meet the preset second target condition, and the fan fault information does not meet the preset third target condition, then acquiring the third target opening value corresponding to the vehicle speed information and ambient temperature information, the fourth target opening value corresponding to the engine intake air temperature information and engine coolant temperature information, the fifth target opening value corresponding to the air conditioning pressure information, the sixth target opening value corresponding to the transmission oil temperature information, and the seventh target opening value corresponding to the hybrid vehicle controller (HCU) information; determining the largest target opening value among the third, fourth, fifth, sixth, and seventh target opening values ​​as the final target opening value; and controlling the active air intake grille to adjust to the final target opening value.

[0132] It should be noted that, in the embodiments of the present invention, since the above steps are the same as the content of steps 301-304, the discussion of the above steps can refer to the discussion of steps 301-304, and will not be repeated here.

[0133] Furthermore, in this embodiment of the invention, obtaining the third target opening value corresponding to vehicle speed information and ambient temperature information, the fourth target opening value corresponding to engine intake air temperature information and engine coolant temperature information, the fifth target opening value corresponding to air conditioning pressure information, the sixth target opening value corresponding to transmission oil temperature information, and the seventh target opening value corresponding to hybrid vehicle controller (HCU) information, respectively, includes: obtaining the third target opening value from a pre-stored relationship table of vehicle speed information, ambient temperature information, and active grille opening value based on vehicle speed information and ambient temperature information; and obtaining the third target opening value from a pre-stored relationship table of engine intake air temperature information and engine coolant temperature information based on engine intake air temperature information and engine coolant temperature information. The system obtains a fourth target opening value from a table relating information to the active grille shutter opening value; and obtains a fifth target opening value from a pre-stored table relating air conditioning pressure information to the active grille shutter opening value based on air conditioning pressure information; and obtains a sixth target opening value from a pre-stored table relating transmission oil temperature information to the active grille shutter opening value based on transmission oil temperature information; and obtains a seventh target opening value from information from the hybrid vehicle controller (HCU). The HCU information is obtained by processing the active grille shutter opening value request information sent by the control unit, where the control unit includes the battery, battery pack, and motor.

[0134] It should be noted that, in this embodiment of the invention, since the above steps are identical to the steps in step 302 which involve obtaining the third target opening value corresponding to vehicle speed information and ambient temperature information, the fourth target opening value corresponding to engine intake air temperature information and engine coolant temperature information, the fifth target opening value corresponding to air conditioning pressure information, the sixth target opening value corresponding to transmission oil temperature information, and the seventh target opening value corresponding to hybrid vehicle controller (HCU) information, the discussion of the above steps can refer to the discussion in step 302 which involves obtaining the third target opening value corresponding to vehicle speed information and ambient temperature information, the fourth target opening value corresponding to engine intake air temperature information and engine coolant temperature information, the fifth target opening value corresponding to air conditioning pressure information, the sixth target opening value corresponding to transmission oil temperature information, and the seventh target opening value corresponding to hybrid vehicle controller (HCU) information, and will not be repeated here.

[0135] This invention provides a control method for an active grille shutter. When the vehicle's power mode is off and the vehicle is a low-spec model, this invention can fully open or close the active grille shutter based on the ambient temperature, thus achieving intelligent control of the grille shutter opening value for low-spec models. This invention applies different active grille shutter opening value control strategies for different vehicle configurations, ensuring that all vehicles, regardless of their configuration, can achieve intelligent control of the grille shutter opening value even when the vehicle's power mode is off. This improves the intelligence of the active grille shutter control while also meeting the needs of different users. The present invention, when the vehicle power mode is powered on, can obtain the corresponding active air intake grille opening value based on different detected information, and finally use the maximum active air intake grille opening value as the final target opening value. This achieves intelligent control of the active air intake grille opening value even when the vehicle is powered on. The present invention obtains the active air intake grille opening value corresponding to different detected information through a pre-stored vehicle relationship table, realizing that the active air intake grille opening value can be obtained directly from the relationship table, improving the efficiency of obtaining the active air intake grille opening value, and thus achieving the technical effect of improving the efficiency of controlling the active air intake grille opening value.
