Problems solved by technology
During the driving of an electric vehicle, if the air intake grille is closed, the air intake in the engine compartment will be blocked, resulting in a great impact on the cooling of the high-pressure components in the engine compartment, and the low-temperature circuit coolant may be due to excessive temperature. And boiling; if the air intake grille is turned on, air can enter the engine compartment to cool the high-voltage components in the engine compartment, but at the same time it will also increase the aerodynamic resistance, requiring the power battery to consume power and energy to overcome the aerodynamic resistance, but in this way It will affect the optimal output of the vehicle's dynamic performance, and the consumption of battery power will affect the cruising range

The present invention provides a control method, a control system and an electric vehicle for an air intake grill of an electric vehicle. The control method includes: when the ignition switch of the vehicle is in the ON gear or the vehicle is in the charging mode, obtaining the outlet of the low-temperature radiator The water temperature, the pressure of the vehicle air conditioner and the vehicle speed; the first opening degree of the air intake grille is determined according to the outlet water temperature of the low temperature radiator, the pressure of the vehicle air conditioner and the vehicle speed; The first opening degree of intake air. The control method of the present invention can improve and save the power consumption of the power battery and improve the driving range of the whole vehicle on the premise of ensuring the performance of the electric vehicle.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method and control system for an electric vehicle air intake grille and the electric vehicle. Background technique [0002] The grille is an important part of the car's front styling and is the inlet for air to flow into the engine bay. At present, in the field of electric vehicles, the air intake grille has only two states: fully open and fully closed. During the driving of an electric vehicle, if the air intake grille is closed, the air intake in the engine compartment will be blocked, resulting in a great impact on the cooling of the high-pressure components in the engine compartment, and the low-temperature circuit coolant may be due to excessive temperature. And boiling; if the air intake grille is turned on, air can enter the engine compartment to cool the high-voltage components in the engine compartment, but at the same time it will also increase the ...
