Abstract

The embodiment of the invention provides a fault detecting method and device for a double-clutch automatic transmission. The method includes the steps that a rotating speed signal corresponding to a rotating speed sensor is collected through the rotating speed sensor in the double-clutch automatic transmission; when it is detected that the rotating speed signal meets the rotating speed condition corresponding to a preset electrical fault, the specific electrical fault type of the rotating speed sensor can be determined; and in the absence of the electrical fault, rotating speed change rate judgment of the rotating speed signal is performed, the judgment is based on the change rate of the rotating speed within the sampling time, and whether the excessively-high rotating speed signal change rate fault exists or not can be determined. The detecting method is simple and effective, the fault type of the detected rotating speed sensor is abundant, and the actual fault type of the rotating speed sensor can be reflected clearly.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of detection, and in particular to a fault detection method and device for a dual-clutch automatic transmission. 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 Shift forks and 1 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 dual-clutch automatic transmission feeds back the working status of the whole machine in real time through the signal collected by the sensor. According to the different types of collected s...
