Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a self-learning method and device for a hydraulic torque converter, electronic equipment, and a storage medium. Background technique [0002] The hydraulic torque converter is installed between the engine and the gearbox, and transmits power through the transmission oil as the medium. It has the functions of torque changing, speed changing and buffering. for friction transmission. The hydraulic transmission torque of the hydraulic torque converter has the advantages of increasing torque, reducing speed, and buffering fluctuations, but at the same time, it has the disadvantage of low transmission efficiency and high heat generation. The disadvantage is that it is impossible to increase the torque and reduce the speed, and there is no impact buffering effect. [0003] At present, after the automatic transmission control software enters the slip cont...

The hydraulic transmission torque of the hydraulic torque converter has the advantages of increasing torque, reducing speed, and buffering fluctuations, but at the same time, it has the disadvantage of low transmission efficiency and high heat generation. The disadvantage is that it is impossible to increase the torque and reduce the speed, and there is no impact buffering effect

[0003] At present, after the automatic transmission control software enters the slip control of the hydraulic torque converter, when the engine speed and torque are determined, different individuals in the same gearbox use the same software-calibrated slip point oil pressure value to control the gearbox Due to the difference of the gearbox, the oil pressure value of the actual sliding point of the gearbox will not match the value set in the software. It can only be adjusted through the corresponding oil pressure adjustment value PI. However, the process of PI adjustment It will make the efficiency of the gearbox or the driving experience of the vehicle worse. After entering the slippery control next time, the software still needs to repeat the above operations
