Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] When the car is detected to start, start the air compressor within the set first time, and when the air compressor runs to the set second time, control the air compressor to stop; the set second time is greater than the air compression The machine inflates the air bag to the set second air pressure threshold.

[0023] When the car is running, when it is detected that the air pressure of the air bag is less than or equal to the set first air pressure threshold, the air compressor is started, and when the air pressure of the air bag is detected that is greater than or equal to the set second air pressure threshold, Control air compressor shutdown.

[0024] Combining with the operating conditions of commercial vehicles, the present invention ensures that the air compressor continues to work for a period of time each time the vehicle is ...

Abstract

The invention relates to a control method and a control device for an air compressor for a vehicle. When an automobile is started, or the air pressure of an air bag is detected in an operating processof the automobile, the air compressor operates for a period of time continuously, so that the temperature of lubricating oil of the air compressor is improved, and water accumulated in the lubricating oil is discharged, and accordingly the condition that the inner structure of the air compressor is corroded and damaged as the lubricating oil is emulsified is avoided, a body and a bearing are lubricated reliably, and the service life of the air compressor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a control method and device for a vehicle air compressor. Background technique [0002] Due to the large curb weight, pure electric commercial vehicles generally use air brakes, and the compressed air comes from electric air compressors (referred to as air compressors). Screw-type and vane-type electric air compressors are widely used due to their good reliability and low vibration and noise. It is used in commercial vehicles, and when the screw and vane compressors are running, in order to take away the heat of air compression, a certain amount of lubricating oil will be sprayed into the compression chamber and lubricating rotors and bearings. After the compression is completed, the compression Air and lubricating oil enter the oil and gas barrel together, and the oil and gas are initially separated in the oil and gas barrel of the air compressor. When the...
