Abstract

The invention particularly discloses a gas path-electric air compressor integrated control system and control method. The system comprises an electric air compressor, wherein the electric air compressor is connected with a pressure regulating valve; an outlet of the pressure regulating valve is connected with a dryer; an output end of the dryer is connected with a one-way valve; the one-way valve is connected with a four-loop protective valve; output ends of the four-loop protective valve are respectively connected with an air storage tank; two of the air storage tanks are respectively provided with an air pressure transducer which is connected with a digital instrument through an electric circuit; a pressure relief port of the dryer is connected with an electromagnetic valve; and the other end of the electromagnetic valve is communicated with atmosphere. The electromagnetic valve is added to the air outlet of the dryer to ensure that the discharge pressure of the dryer can be achieved in every air inflation, so that the dryer can discharge air and water, thereby prolonging the service life of the dryer.

Description

[0001] technical field [0002] The invention relates to the field of design and manufacture of new energy vehicles, in particular to an integrated control system and control method for an air circuit and an electric air compressor. Background technique [0003] With the increasing air pollution and the gradual depletion of oil resources, electric vehicles are considered to be one of the inevitable choices for the transformation and upgrading of the automobile industry. At the same time that electric vehicles are converted from engine drive to electric motor drive, the air compressors used for braking and auxiliary systems are changed from engine drive to electric air compressors, so their control methods have also changed. [0004] At present, the general electric air compressor control method is to add an air pressure switch on the main air circuit, use the air pressure switch to sense the pressure in the air storage tank, and realize the on-off of the pressure switch by s...
