Embodiment Construction

[0041] It can be seen from the background art that in the prior art, when selecting or shifting gears, the shift fork cannot accurately reach the threshold range of the target position.

[0042] In a car, the gearshift mechanism of the transmission includes a selector shaft, a shift fork shaft and a shift fork, wherein the shift fork is set on the shift fork shaft and can move along the axial direction of the shift fork shaft , the shift fork includes a fixedly connected shift fork and a finger groove, and the finger grooves of each shift fork are arranged along the axis of the selector shift shaft, and the shift finger is fixed on the select shift shaft. When the finger is driven by the gear selection shaft and moves along the axis of the gear selection shaft, it can be located in the finger slots of different shift forks to achieve gear selection. Further, it can be driven by the rotation of the gear selection shaft The shift fork moves along the axial direction of the fork ...

Abstract

The embodiment of the invention provides a gear shifting control method and device and a readable storage medium. The gear shifting control method comprises the following steps of acquiring the actualposition of the current moment of the gear selecting and shaft shifting; when the distance between the actual position of the current moment and the preset target position does not meet the distancethreshold value, and acquiring the position preset voltage of a gear selecting motor according to the target position and the actual position of the current moment; and when the position difference value of the actual position of the current moment and the actual position of the previous acquisition moment does not meet the position difference value threshold value, adjusting the position preset voltage to obtain the position control voltage at the current moment, controlling the gear selecting motor to operate under the position control voltage, so that the position of the gear selecting andshaft shifting approaches to the target position. According to the gear shifting control method and device and the readable storage medium, the accuracy of the threshold range of a shifting fork reaching the target position can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of automobiles, in particular to a gear shift control method, device and readable storage medium. Background technique [0002] Automobile transmission is the main component to realize vehicle speed control and driving force control in the process of automobile form. With the development of technology, manual transmission and automatic transmission have appeared. Among them, automatic transmission includes automatic manual transmission (AMT, Automatic Manual Transmission) , Automatic manual transmission refers to a stepped mechanical automatic transmission that is based on the traditional dry clutch and manual gear transmission, with the addition of an electronic control system and the transformation of the manual shift mechanism into an automatic shift mechanism, thereby realizing automatic shift. [0003] When the gears of the automatic manual transmission are changed, the electric motor wi...
