AI Technical Summary

Problems solved by technology

The deviation of the pressure sensor leads to fluctuations in the expected pressure or inaccurate control during the pressure control process, which makes the clutch pressure too large or too small, causing the gearbox to vibrate

Abstract

The invention discloses a diagnosis method for a pressure sensor of a dual-clutch automatic transmission. The method comprises a clutch opening condition diagnose mode, a clutch pre-flushing oil condition diagnosing mode and a clutch intermittent condition diagnosing mode. The diagnosis method for the pressure sensor of the dual-clutch automatic transmission can effectively diagnose whether the pressure sensor is normal or not by diagnosing whether clutches work normally under different working conditions of the clutches, and is conducive to providing guidance for maintenance of the pressure sensor.

Description

technical field [0001] The invention relates to the field of transmissions, in particular to a diagnostic method for a pressure sensor of a dual-clutch automatic transmission. Background technique [0002] A typical wet dual-clutch automatic transmission consists of two coaxial nested or parallel clutches, two coaxial and inner and outer nested input shafts, two parallel output shafts, and multiple synchronous clutches arranged on the output shafts. It consists of a shifter device, multiple shift forks and a differential. The odd and even gear input gears of the transmission are respectively arranged on two input shafts. Through the switching of two clutches and the action of different synchronizers, torque conversion and output are realized through different output shafts. The transmission power flow is: engine output torque→dual clutch →Transmission input shaft→Transmission output shaft→Wheels. During the transmission of the entire power flow, the dual clutch will engage...
