Distribution control mechanism and control method for vehicle compressed air as well as vehicle

Abstract

The invention discloses a distribution control mechanism and control method for vehicle compressed air as well as a vehicle. The distribution control mechanism comprises a first valve and two second valves, wherein the first valve comprises a first valve air inlet, a first valve air release port, a first valve stop position and a first valve air outlet; the first valve air outlet communicates withthe first valve air inlet or the first valve air release port or the first valve stop position; the second valve comprises a second valve air inlet, a second valve air outlet and a second valve stopposition, and the second valve air inlet communicates with the second valve air outlet or the second valve stop position; the first valve air outlet separately communicates with second valve air inlets of wo second valves through pipelines; pressure sensors are arranged on the pipelines; and the first valve, the second valves and the pressure sensors are all electrically connected to a controller.According to the characteristic that two air use units of a vehicle have compressed air use requirements in different time periods, real-time and on-demand control and distribution of compressed airare achieved through a simple and standard duty ratio valve and a switch valve structure.

Description

technical field [0001] The invention discloses a compressed air distribution control valve used in the automobile industry, belongs to the technical field of electromagnetic valve groups for vehicles, and specifically discloses a distribution control mechanism, a control method and a vehicle for compressed air for vehicles. Background technique [0002] With the continuous development of science and technology, vehicle compressed air technology has been widely used by major manufacturers. Ordinary vehicles include one air supply unit and two gas consumption units, and the two gas consumption units have different pressure and flow characteristics of gas demand, so in the prior art, the gas supply unit for each gas consumption unit is generally Control, matching two mutually independent pressure regulating mechanisms and controllers to realize real-time and on-demand control of pressure and flow. The above-mentioned controller unit, pressure regulating structure and pressure s...

Problems solved by technology

Ordinary vehicles include one air supply unit and two gas consumption units, and the two gas consumption units have different pressure and flow characteristics of gas demand, so in the prior art, the gas supply unit for each gas consumption unit is generally Control, matching two mutually independent pressure regulating mechanisms and controllers to realize real-time and on-demand control of pressure and flow. The above-mentioned controller unit, pressure regulating structure and pressure sensor, hardware and software have complex structures, high costs, and control parameters. It also requires separate calibration and verification, cannot be reused, and has technical problems such as long development cycle
