Clutch transmission torque self-learning method, device and equipment and readable storage medium

Abstract

The invention relates to a clutch transmission torque self-learning method, device and equipment and a readable storage medium. The clutch transmission torque self-learning method comprises the steps that first displacement and first transmission torque of a clutch contact point and second displacement and second transmission torque of a complete combination point are obtained; when the working condition of a vehicle in the starting process meets the preset self-learning condition, a clutch is controlled to be slowly combined, and when the torque and the rotating speed are larger than the corresponding threshold values correspondingly and the torque change rate and the rotating speed change rate are located in the corresponding change rate ranges correspondingly, third displacement of the clutch is recorded, and third transmission torque is calculated; and when the difference value percentage of the calibrated transmission torque and the third transmission torque is greater than a threshold value, a calibrated transmission torque line is updated based on the first displacement, the first transmission torque, the second displacement, the second transmission torque, the third displacement and the third transmission torque to complete transmission torque self-learning. According to the method, learning of the transmission torque and updating of the transmission torque line can be automatically completed in the starting process of the vehicle, and the driving comfort is improved.

Description

Technical field [0001] The present application relates to the field of automotive technology, and in particular, to a clutch transmission torque self-learning method, apparatus, device, and readable storage medium. Background technique [0002] Today, the number of automobile manufacturing technology continues to reform and innovation, the number of cars is also increasing, and it has become an indispensable means of work and life; at the same time, with the continuous improvement of living standards, People also have to pursue comfort during the driving process. Among them, the clutch is used as a key component for ensuring smooth operation of the vehicle, which is typically composed of a friction sheet, a spring sheet, a pressure plate, and a power output shaft, disposed between the engine and the gearbox, used to put the engine flywheel The stored torque is transmitted to the gearbox to ensure that the vehicle is transmitted to the driving force and torque of the drive wheel u...
