Abstract

The invention discloses an automatic speed changing method based on a manual gearbox and a system. The automatic speed changing method includes controlling linkage of a clutch actuating mechanism and a clutch to realize engaging and disengaging and controlling linkage of a gear shifting actuating mechanism and the gearbox to change a gear position by a central processing unit according to obtained vehicle driving state information. The automatic speed changing method and the system have the advantages that 1, a working mode is an automatic step speed change mode, the characteristic of high-torque output of a manual speed changing mode is inherited, automatic gear shifting can be realized, and the automatic speed changing method and the system can be applied to heavy-duty goods vehicles and public transport vehicles; 2, speed-changing gear shifting is completed hydraulically or by the aid of a motor controlled by an ECU (electronic control unit) on the basis of manual speed changing, and manufacturing cost is low; and 3, shortcomings of a hydraulic torque converter are overcome due to an automatic control effect of the ECU, and power loss of an engine is greatly reduced.

Description

technical field [0001] The invention belongs to the shifting technology, and in particular relates to an automatic shifting method and system based on a manual gearbox. Background technique [0002] There are three types of transmission methods in cars: manual transmission, automatic transmission and continuously variable transmission. A car with a manual gearbox transmits power completely through the meshing of the gears and the ratio of the transmission ratio, and its output torque is large. Due to this feature, many large cars and buses have always used the manual transmission method. However, the traditional manual gearbox needs to change the gearbox gear frequently, which makes driving a car more difficult and labor-intensive. Thereby automatic transmission has occurred, and on the automobile of automatic transmission, the road condition change of adapting to the outside world by the automatic transformation of transmission gear, thus makes labor intensity and manipula...
