Automobile transmission lubricating oil gas content detection system, method and device and storage medium

Abstract

The invention discloses an automobile transmission lubricating oil gas content detection system, method and device and a storage medium. The method comprises the following steps: acquiring a gas content detection demand; generating a reversing valve control signal according to the gas content detection requirement, so that a reversing valve switches an oil way according to the reversing valve control signal, and the working mode of the detection system is switched; generating a pressure control signal according to the oil way pressure of the first oil way / the second oil way so as to control the oil way pressure in the first oil way / the second oil way; generating a flow control signal according to the oil way flow of the first oil way / the second oil way so as to control the oil way flow in the first oil way / the second oil way; and generating a detection control signal according to the gas content detection requirement, so that the gas content detection unit detects the gas content in the lubricating oil according to the detection control signal. According to the invention, the gas content of lubricating oil under a power-source-free oil path can be detected, the pressure and flow of a medium entering gas content detection equipment can be controlled, and the gas content detection equipment does not need to be frequently disassembled.

Description

technical field [0001] The present invention relates to the technical field of automobile transmissions, in particular to a detection system, method, device and computer-readable storage medium for the gas content of lubricating oil in automobile transmissions. Background technique [0002] At present, most automobile OEMs have not carried out air content test tests on transmission lubricating oil. Even if the air content in automobile transmission lubricating oil is tested, the existing air content detection equipment is directly connected to the hydraulic oil circuit. Read the air content value in the lubricating oil. This approach has the following problems: [0003] (1) Since the gas content detection equipment generally does not have an oil pumping device, it is impossible to detect the gas content of the lubricating oil under the oil circuit without power source; for example, it is impossible to detect the gas content of the stationary lubricating oil in the oil tank;...

Problems solved by technology

[0003] (1) Since the gas content detection equipment generally does not have an oil pumping device, it is impossible to detect the gas content of the lubricating oil under the oil circuit without power source; for example, it is impossible to detect the gas content of the stationary lubricating oil in the oil tank;

[0004] (2) Most gas content detection equipment cannot control the flow and pressure of the medium entering the equipment;

[0005] (3) When the gas content value is periodically detected, it is necessary to frequently disassemble the gas content detection equipment
