Embodiment

[0034] see figure 1 , a method for detecting and responding to an unexpected action of a clutch actuator, the method comprising the following steps:

[0035] A. Real-time monitoring of the command and status of the clutch when the clutch is fully disengaged; real-time monitoring of the command and status of the clutch when the clutch is fully engaged;

[0036] By installing a clutch position sensor in the automatic transmission, the current position of the clutch is monitored in real time to determine the real-time state of the clutch;

[0037] B. When the vehicle conditions are satisfied, when the clutch command is in the state of maintaining disengagement, but the actual state of the clutch changes, it is judged that the clutch actuator has an undesired combination, enters the pre-failure state, and disengages the clutch immediately. At the same time, the number of faults is counted, and if the number of consecutive occurrences is greater than or equal to 3, the fault is di...

Abstract

The invention discloses a detecting and coping method for unexpected actions of a clutch actuator. The detecting and coping method for the unexpected actions of the clutch actuator comprises the following steps that the command and the state of a clutch are monitored in real time when the clutch is in a completely separated (combined) state; on the condition that the whole vehicle conditions are met, when the command of the clutch is in a separated (combined) state, but the actual state of the clutch changes, it is judged that the clutch actuator generates unexpected combination (separation),the clutch is in a preliminary fault state, the clutch is immediately separated (combined), the fault number is counted, and if faults are continuously generated multiple times, the faults are determined; and after the faults are determined, the current gear is kept, the clutch is forcedly combined (separated), the gear is automatically switched to the neutral gear after parking, and the faults are displayed on a vehicle instrument to remind a driver to go to a service station for maintenance in time. According to the detecting and coping method for the unexpected actions of the clutch actuator, the fault detection method is simple, the accuracy is high, the fault coping method is high in reliability, and the safety performance of a vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobile design, in particular to a method for detecting and dealing with an unexpected action of a clutch actuator, which is mainly suitable for detecting and dealing with the unexpected combination and separation of a clutch actuator. Background technique [0002] With the development of automatic transmission technology, electromechanical automatic transmission (AMT) has become an important development direction of automatic transmission due to its simple structure, high transmission efficiency and low cost, and the number of cars equipped with AMT has been steadily increasing year by year. rise. The key technology of developing AMT automatic transmission lies in the automatic control of its own clutch. The control accuracy and performance of AMT clutch directly affect the working performance of AMT automatic transmission and even the starting and shifting quality of the whole vehicle. During the dr...
