Abstract

The invention relates to the technical field of transmissions, and provides a hydraulic torque converter signal authenticity judgment method and a system. The method comprises the steps of: obtaining present rotating speed of an engine of a vehicle, the driving speed and a current parameter of a hydraulic torque converter locking control electromagnetic valve; comparing the obtained rotating speed of the engine, the driving speed and the current parameter of the hydraulic torque converter locking control electromagnetic valve with preset rotating speed calibration value, vehicle speed calibration value and current parameter calibration value through initial conditions; continuously monitoring contents of the initial conditions in a preset continuous monitoring time period to judge authenticity of hydraulic torque converter signals; and a transmission control unit obtaining true current signals of a hydraulic torque converter and an accurate working state of the hydraulic torque converter to improve the gear shifting quality of transmissions.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, in particular to a method and system for judging the authenticity of a hydraulic torque converter signal. Background technique [0002] The hydraulic torque converter is the connecting part between the engine and the gearbox of an automatic transmission car, and uses hydraulic oil as the working medium. The role of the torque converter is to transmit the speed and torque, and the second is to make the connection between the engine and the automatic transmission non-rigid, so as to facilitate the automatic gear shifting of the automatic transmission. Therefore, the hydraulic torque converter plays a vital role in the entire transmission shifting process. [0003] The hydraulic torque converter mainly includes the shell, the guide wheel, the turbine and the pump wheel and other structures. Its actual working process has two states, one is the locked state, and the other is the unlocked state. Un...
