Embodiment Construction

[0051] Generally, the main control strategy for the start and stop of the air compressor of pure electric vehicles can be: install a pressure sensor on the air storage tank. When the pressure sensor detects that the pressure in the air storage tank reaches the set minimum air pressure, the pressure sensor will reach the minimum pressure. The air pressure signal is transmitted to the vehicle controller (VCU for short), and the VCU will control the air compressor to start running; when the pressure sensor detects that the pressure in the air storage tank reaches the set maximum air pressure, the pressure sensor will reach the maximum air pressure. The signal is transmitted to the VCU, so that the VCU controls the air compressor to stop running; among them, the pressure regulating spring of the air dryer will control the unloading pressure, when the unloading pressure is reached, the exhaust port of the air dryer will be opened, and the air compressor will run idling To unload, at...

Abstract

The invention provides a control system and method for a vehicle air compressor. The control system comprises an air compressor, a dryer, a gas storage cylinder unit and a pneumatic brake valve whichare connected in sequence, a dryer pressure switch in circuit connection with the dryer, a gas storage cylinder pressure switch in circuit connection with the gas storage cylinder unit, a pressure sensor for detecting gas pressure at the gas brake valve, a detecting unit for detecting the state of a dryer pressure switch and a gas storage cylinder pressure switch, and a whole car controller configured to control the air compressor to be operated when the dryer pressure switch and the gas storage cylinder pressure switch are turned off and the pressure value at the gas brake valve is smaller than a first gas pressure value. The problems that in the prior art, the operation status of the air compressor is controlled only through the detection condition of the pressure sensor, so that starting and stopping of the air compressor are not accurate, and unloading of the air dryer is not accurate are solved.

Description

technical field [0001] The invention relates to the field of vehicle air compressors, in particular to a control system and control method for vehicle air compressors. Background technique [0002] The vehicle air compressor is the power source of the vehicle pneumatic system. The air compressor is mainly used to provide compressed air for the pneumatic brake system. The air compressor fills the compressed gas into the air storage tank through the air dryer. However, in the prior art, the control scheme for starting and stopping the air compressor of pure electric vehicles generally only detects the pressure in the air storage tank through the pressure sensor on the air storage tank, so as to determine the working state of the air compressor according to the detection state of the pressure sensor. In this way, on the one hand, the control scheme cannot accurately control the start and stop of the air compressor and the unloading of the air dryer; on the other hand, the contr...
