Self-learning method and device, electronic equipment and storage medium of hydraulic torque converter

Abstract

The invention discloses a self-learning method and device of a hydraulic torque converter, electronic equipment and a storage medium. The self-learning method of the hydraulic torque converter includes obtaining the oil pressure adjustment value of the sliding friction point corresponding to the hydraulic torque converter; Obtain the corresponding sliding point oil pressure learning value of the hydraulic torque converter according to the sliding point oil pressure adjustment value; obtain the gearbox control hydraulic torque converter according to the sliding point oil pressure calibration value and the sliding point oil pressure learning value Oil pressure command value. Through the technical solution of the present invention, it is beneficial to realize the self-learning function of the hydraulic torque converter triggered according to the state of the oil pressure adjustment value of the sliding point, and the process of adjusting the oil pressure according to the oil pressure adjustment value of the sliding point is omitted, which is beneficial Make the hydraulic torque converter realize the slippery friction control in the ideal state in time.

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
