Example Embodiment

[0049] Example 1

[0050] This embodiment is applied to an electric vehicle equipped with an active air intake grille assembly as an example. The electric vehicle is equipped with a battery power system, a cooling system for cooling the power system, an active air intake grille assembly, etc. The cooling system includes Circulating coolant and its pipeline. The air intake grille assembly includes rotatable blades, and the blades are connected with a driving device for driving the blades to open or close and adjust the opening degree of the blades.

[0051] Reference figure 1 The control device for the intake grille assembly provided in this embodiment includes: a first temperature detection module 1, a second temperature detection module 2, and a control module 3.

[0052] The first temperature detection module 1 is used to detect the temperature of the coolant in the automobile cooling system. Specifically, the first temperature detection module 1 includes one or more temperature ...

Example Embodiment

[0068] Example 2

[0069] When the measured ambient temperature is below zero, if the environment where the car is driving is usually free of rain or snow, always maintaining a safe opening during driving will increase the wind resistance of the car, increase energy consumption, and cause unnecessary energy waste. This embodiment provides a more optimal embodiment to solve how to avoid energy waste while avoiding the failure of the air intake grille caused by the freezing of the blades.

[0070] Reference image 3 In addition to the same configuration as the first embodiment, the control device for the air intake grille assembly provided by this embodiment also includes a rain and snow state detection module 5 connected to the control module 3, and the rain and snow state detection module 5 is used to detect The state of rain and snow in the environment. The rain and snow state detection module 5 may include, but is not limited to, one or more of a rain sensor for detecting whethe...

Abstract

The invention relates to the technical field of automobile control. The problem that in a running process of an existing vehicle provided with an active air inlet grille, due to the fact that blades are frozen easily, the air inlet grille loses efficacy is solved. Therefore, the invention provides a control method and a control device for an air inlet grille assembly of the vehicle; the air inletgrille assembly comprises rotatable blades, and the control device comprises a first temperature detection module, a second temperature detection module, and a control module; the first temperature detection module is used for detecting the temperature of a cooling liquid in a vehicle cooling system; the second temperature detection module is used for detecting the environment temperature; and thecontrol module is connected with the two temperature detection modules and used for selectively controlling the opening degree of the blades according to a detection result of the second temperaturedetection module when the cooling liquid temperature detected by the first temperature detection module is lower than a preset temperature threshold value. According to the control device provided bythe invention, when the vehicle is in a low-temperature environment, the air inlet grille blades can keep a safe opening degree, so that the problem that the air inlet grille loses efficacy due to thefact that the blades are frozen in a completely closed state is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a control method and a control device for a vehicle air intake grille assembly. Background technique [0002] Existing automobiles are all equipped with a cooling system, which uses the coolant circulated in the cooling system to cool down the engine or the car battery. The coolant is usually a mixture of ethylene glycol and water. In some cases, the heat exchange capacity of the coolant is insufficient, and it is necessary to use circulating air to assist in cooling. The air enters from the air intake grille at the head of the car body, but air cooling is not required in all cases. Continuing to take in the wind when air cooling is required will increase the driving resistance, thereby increasing energy consumption. In order to take into account both the air cooling function and the wind resistance reduction function, the active air intake grille came into being. Th...
