Problems solved by technology

[0005] During the shifting process, there will always be failures such as stuck, unable to complete the operation of engaging or removing the gear for a long time, and the displacement value of the fork exceeds the limit. Such failures are sometimes only occasional accidents. After the fork, it can return to normal. However, when such a fault occurs in the current gearbox, it generally disengages the corresponding clutch directly, waits for the fault to recover after restarting, or manually checks the fault, and cannot carry out relevant adaptive recovery measures, which affects the gearbox.

Embodiment Construction

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0033] Such as figure 1 As shown, the embodiment of the present invention provides an adaptive control method for synchronizer shifting faults, which can generally be realized by control software. First, the gearbox control software will detect whether the synchronizer shift control produces a sticking of the shift fork, gear shifting or When there are faults such as excessive shifting time, shifting fork displacement exceeding the characteristic limit, and accidental shifting of the gear position, the preparation conditions for adaptive...

Abstract

The invention discloses a synchronizer gear-shifting fault adaptive control method. The control method comprises the steps of driving a shifting fork through a driving component after verifying that the driving component of the shifting fork works, so that the shifting fork is switched among different positions and the purpose of adaptive recovery processing of synchronizer gear-shifting fault is achieved; at the same time, recording the displacement values of the shifting fork at different positions, and judging whether the synchronizer gear-shifting fault is removed finally; and if the synchronizer gear-shifting fault is not removed, perform repair. According to the control method disclosed by the invention, adaptive recovery of accidents can be conducted, and complex operations, such as unnecessary clutch release, are avoided; the service life of a transmission is prolonged, and the user convenience is also improved greatly; moreover, with the control method, whether gear-shifting fault occurs in a synchronizer can be judged accurately so as to facilitate people to repair equipment in time, and the customer satisfaction is improved greatly.

Description

technical field [0001] The invention relates to the field of vehicle transmission, in particular to an adaptive control method for synchronizer gear shift failure. Background technique [0002] Dual-clutch automatic transmission includes two coaxial nested or parallel arranged clutches, coaxial, inner and outer inner and outer nested input shafts and outer input shafts, output shafts, multiple synchronizer devices arranged on the output shafts, multiple It consists of a shift fork and a differential. The driving gears of the odd and even gears of the transmission are arranged on the inner and outer input shafts respectively, through the switching of two clutches and the actions of different synchronizers, torque conversion and output are realized. [0003] The main components of the shift mechanism are the synchronizer device and the shift fork, the shift fork is supported by the linear bearing in the shift piston cylinder liner, and the shift piston cylinder liner is press...
