The following describes in detail a control method, a device, a storage medium and a vehicle of an active air intake grille provided by the embodiment of the application through specific embodiments and application scenes thereof with reference to the accompanying drawings.
A first embodiment of the present invention relates to a control method of an active intake grille, applied to an engine electronic control module (Engine Control Module, ECM), the flowchart of which is shown in fig. 1, comprising:
Step 101, obtaining a current whole vehicle power supply mode.
It should be noted that, in the embodiment of the present invention, the electronic control module (Engine Control Module, ECM) of the engine needs to acquire the current vehicle power mode of the vehicle, where the vehicle power mode includes a power-on mode or a power-off mode.
Step 102, when the whole vehicle power supply mode is in the power-down mode, configuration information of the vehicle is obtained, wherein the configuration information comprises first configuration information and second configuration information, the first configuration information is used for indicating that the vehicle is a high-configuration vehicle type, and the second configuration information is used for indicating that the vehicle is a low-configuration vehicle type.
It should be noted that, in the embodiment of the present invention, when the power mode of the whole vehicle is the power-down mode, the electronic engine control module (Engine Control Module, ECM) obtains the configuration information of the current vehicle, where the configuration information of the vehicle includes the first configuration information and the second configuration information. In order to enable those skilled in the art to easily understand, the first configuration information refers to the current vehicle being a high-vehicle model, and the second configuration information refers to the current vehicle being a low-vehicle model.
Further, as shown in fig. 2, step 101 further includes the steps of:

Step 202, judging whether the fan duty ratio information is larger than or equal to a preset first threshold value, whether the engine water temperature sensor fault information accords with a preset second target condition and whether the fan fault information accords with a preset third target condition.
In the embodiment of the present invention, the preset first threshold is 50%, the preset second target condition is an engine water temperature sensor fault, and the preset third target condition is a fan fault. The engine electronic control module (Engine Control Module, ECM) judges whether the fan duty ratio is more than or equal to 50% according to the obtained fan duty ratio information, judges whether the engine water temperature sensor is faulty according to the obtained engine water temperature sensor fault information, and judges whether the fan is faulty according to the obtained fan fault information.

Step 302, if the fan duty cycle information is smaller than the preset first threshold, the engine water 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 a third target opening value corresponding to the vehicle speed information and the environment temperature information, a fourth target opening value corresponding to the engine air inlet temperature information and the engine water temperature information, a fifth target opening value corresponding to the air conditioner pressure information, a sixth target opening value corresponding to the transmission oil temperature information, and a seventh target opening value corresponding to the hybrid vehicle controller HCU information are respectively obtained.
