Problems solved by technology

[0004] At present, it is generally to flush the solenoid valve before shifting gears to prevent sticking, or simply solve the problem of solenoid valve sticking. These solutions cannot accurately detect faults during and after shifting Clutch judgment, and take countermeasures that do not affect driving safety, and control the stuck solenoid valve at the same time

Embodiment Construction

[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only for illustration and are not intended to limit the present invention.

[0043] The present invention provides a clutch solenoid valve stuck monitoring and protection method in the process of shifting gears, such as figure 1 shown, including the following steps:

[0044] S1: During the driving process of the car, the automatic transmission receives the shift signal from the controller and starts to switch from the current gear to the target gear. The shift process involves changing the power state of the solenoid valve in the hydraulic system to engage the clutch C1; the shift process After the middle oil filling phase, in the torque phase "I", the detector collects the turbine speed and the output shaft speed of the automa...

Abstract

The invention discloses a clutch electromagnetic valve sticking monitoring and protection method and device in the process of shifting gears. Through the speed detection in the process of shifting gears, the clutch that may be faulty can be positioned in advance, and combined with the detection of clutch slippage, it can accurately Judging whether the solenoid valve corresponding to the clutch is stuck, and at the same time, restricting gear driving for the faulty gear can ensure driving safety and prevent clutch wear from increasing. In addition, the non-impact current flushing control of the stuck solenoid valve can effectively solve the problem. Stuck phenomenon. Compared with the existing monitoring and protection methods, the present invention provides a more accurate positioning of the faulty clutch and a judgment strategy for the sticking of the solenoid valve and a faster solution to the sticking of the solenoid valve, and can detect and fix the faulty clutch during the shifting process. Positioning, and at the same time effectively prevent and deal with stuck solenoid valves.

Description

technical field [0001] The invention relates to the technical field of automatic transmission clutch control, in particular to a method and device for monitoring and protecting clutch solenoid valve sticking during gear shifting. Background technique [0002] With the increasing maturity of automobile technology, people's requirements for automobile power, comfort, safety and economy are also increasing. The transmission is a key link in the car transmission system, and its effect directly affects the driving performance of the car. At present, automatic transmissions have become the mainstream of transmissions due to their excellent performance such as convenient operation and high-efficiency shifting. [0003] In an automatic transmission, the clutch is an important element to perform gear shifting. The opening and closing of the clutch is controlled by the hydraulic system, and the working conditions of the corresponding solenoid valves in the hydraulic system directly ...
