Abstract

The embodiment of the invention discloses a gear case gear-shifting control device, a gear-shifting control method and a gear case. The gear case gear-shifting control device comprises at least one shifting fork and at least one shifting executing mechanism, a first position sensor, a second position sensor, and a control module; the first position sensor is arranged on the shifting fork and usedfor acquiring the first position information of the shifting fork; the second position sensor is arranged on the shifting executing mechanism and used for acquiring the second position information ofthe shifting executing mechanism; the control module is used for acquiring the first position information and the second position information, and comparing the first position information with the second position information to obtain position bias, and confirming the gear position information of the gear box according to the position bias. The embodiment further discloses the gear-shifting control method and the gear case, which can improve the shifting success rate and the reliability of the gear box.

Description

technical field [0001] Embodiments of the present invention relate to vehicle control technologies, and in particular to a gear shift control device, a gear shift control method, and a gear box. Background technique [0002] With the rapid development of automotive electronic control technology and single-chip microcomputer technology, automatic transmissions are more and more widely used. Among them, the electronically controlled mechanical automatic transmission (AMT) is to install an electronically controlled shift actuator on the traditional mechanical transmission to realize the gear shifting of the transmission, which has the advantages of high transmission efficiency, low cost, and fuel consumption saving. [0003] However, the AMT used in the current market has always had a problem with the reliability of gear shifting. This problem mainly focuses on the problems of the actuator not being able to remove the gear, the gear selection is not in place, and the gear is no...
