[0069] Based on the above-mentioned first embodiment, the clutch fault diagnosis method of this embodiment, after the step S30, further includes:

[0070] Step S301: When the current pressure value is less than the half junction pressure, determine whether the current pressure value is greater than or equal to a preset pressure threshold, wherein the preset pressure threshold is smaller than the half junction pressure.

[0071] It should be noted that, when the preset diagnosis trigger condition is satisfied, the current voltage value of the pressure sensor is obtained in real time; the current voltage value is converted into a current pressure value; and whether the current pressure value is greater than or equal to the half junction point pressure is judged; When the current pressure value is less than the half junction pressure, it is judged whether the current pressure value is greater than or equal to a preset pressure threshold, wherein the preset pressure threshold is sm...

Abstract

The invention belongs to the technical field of vehicle fault diagnosis, and discloses a clutch fault diagnosis method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a current voltage value of a pressure sensor in real time when a preset diagnosis triggering condition is met; converting the current voltage value into a current pressure value; judging whether or not the current pressure value is larger than or equal to semi-binding-point pressure; when the current pressure value is larger than or equal to the semi-binding-point pressure, opening a clutch, and affirming that there is no electrical fault occurring to the clutch. According to the clutch fault diagnosis method, when it is detected that the current pressure value exceeds the semi-binding-point pressure, it is judged that a vehicle may be in danger, fault response measures are taken, and the situation that the clutch is opened with brute force, and then the vehicle enters alimp mode is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile fault diagnosis, in particular to a clutch fault diagnosis method, device, electronic equipment and storage medium. Background technique [0002] A typical wet dual-clutch automatic transmission consists of two coaxial nested or parallel arranged clutches, two coaxial and inner and outer nested input shafts, two parallel output shafts, and multiple clutches arranged on the output shafts. Synchronizer unit, 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: the engine output torque to the transmission input From the shaft to the dual clutch to the transmission output shaft to the wheels, during the entire power flow tran...
