Abstract

The present application discloses a control method of a synchronizer, which includes obtaining the self-learning result of the minimum synchronization point of the synchronizer in each gear; the self-learning result represents the test value of the minimum synchronization point of the synchronizer; and then, according to The self-learning result determines the position of the minimum synchronization point of each gear; finally, the synchronizer is controlled to move according to the position of the minimum synchronization point, so as to realize the gear shifting operation. Compared with the traditional shifting method, the method provided in this embodiment can perform self-learning for each gearbox, fully considering the differences caused by the gearbox hardware itself and assembly, therefore, the minimum synchronization point determined based on the self-learning method is more accurate. Accurate, so as to realize the precise control of the synchronizer, reduce the probability of hitting the tooth or hitting the end point, and the shifting is more precise. The application also discloses a control device for a synchronizer.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a method and device for controlling a synchronizer. Background technique [0002] With the development of science and technology, vehicles have become an indispensable means of transportation for travel. In industrial production, it also plays an important role as a means of transportation. Due to factors such as road surface quality and traffic congestion, it is often necessary to adjust the vehicle speed adaptively. The vehicle speed adjustment is realized through the gearbox, and the performance of the gearbox directly determines the quality of the vehicle's speed adjustment. [0003] Among them, the synchronizer is a key component of various types of gearboxes, without which the normal gear shifting of the gearbox cannot be completed. The quality of the control of the synchronizer greatly affects the shift quality of the gearbox and thus the driving comfo...
