Embodiment Construction

[0025] The present invention is described in detail below, which is a preferred embodiment among various implementations of the present invention.

[0026] In a preferred embodiment,

[0027] A method for controlling a smart grid network based on LIN, comprising the steps of: (1) installing a smart grid module on the grid to form a smart grid; (2) an engine management system judging the vehicle state; (3) engine management The system determines the opening and closing of the grille and / or the opening range according to the judgment result of step (2); (4) the communication between the engine management system and the smart grille module realizes intelligent Grid opening and closing control, and / or fault finding.

[0028] The smart grid module includes a grid and a smart grid module, and the smart grid module is connected to the grid and can control its opening and closing and opening range. The judgment of the vehicle state in step (2) includes judging the water temperature,...

Abstract

The invention relates to a method for LIN-based intelligent grid network control. The method comprises a step (1) of arranging an intelligent grid module on a grid to form an intelligent grid; a step (2) of performing a full vehicle state judgment by an engine management system; a step (3) determining, by the engine management system, grid opening and closing and / or opening range according to judgment results of the step (2); a step (4) of causing the engine management system to communicate with the intelligent grid module through a LIN bus; and a step (5) of implementing opening and closing control of the intelligent grid and / or fault query through the communication in the step (4). By the communication between the engine management system and the intelligent grid module through the LIN bus, the opening and closing control of the grid and fault query are implemented, a harness is simplified, the cost is reduced, fuel economy is improved, the wind resistance coefficient and oil consumption are reduced, and the network communication efficiency and reliability are improved.

Description

technical field [0001] The invention relates to the field of vehicle state control, in particular to a LIN-based intelligent grid network control method. Background technique [0002] At present, the air pollution in cities is serious, how to reduce vehicle fuel consumption, reduce emissions, and improve fuel economy has become a topic of great concern to major OEMs. The smart grille is a kind of car air intake grille device, which is installed at the grille opening in front of the radiator. Compared with the ordinary air intake grille, the smart grille has electric blades that can rotate 90°, and can adjust the intake angle of the air intake grille in time according to the temperature of the engine water (close the vent when cooling is not needed), and has the function of lowering the temperature of the car. Drag coefficient, shorten engine warm-up time, reduce fuel consumption, improve vehicle dynamic performance and other characteristics. For example, when driving at lo...
