A system and method for identifying congestion conditions and correcting automatic gear shifting

Abstract

The invention discloses a congestion working condition recognition and automatic speed changing and gear shifting correction system and method. The system is characterized by comprising a signal processing module, a congestion working condition recognition module, a gear shifting correction module and an electromagnetic valve driving module. The signal processing module comprises a training sample obtaining module and a recognition sample obtaining module. The congestion working condition recognition module comprises a T-S fuzzy neural network training module and a T-S fuzzy neural network recognition module. Sensor signals are collected and calculated, so that a training sample and a recognition sample are obtained; a T-S fuzzy neural network recognition system is trained, congestion working conditions are recognized and graded, and the automatic speed changing basic gear shifting rule is corrected through the congestion grade. The congestion working conditions can be effectively recognized, automatic speed changing and gear shifting correction is carried out, frequent gear shifting under the congestion working condition is avoided, and abrasion on a gear shifting execution component and a brake system is reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic transmission control for vehicles, in particular to a system and method for identification of congested working conditions and automatic transmission and shift correction. Background technique [0002] A general vehicle automatic transmission includes a number of transmission gears and clutches. Shifting is to control the combination and separation of the clutches according to the speed ratio of the transmission input shaft and output shaft required by the vehicle, so that the speed ratio of the transmission input shaft and output shaft becomes a new one. speed ratio. [0003] Automatic shifting control technology is the key technology of vehicle shifting control. Automatic shifting control mainly includes single-parameter, two-parameter, three-parameter, and even four-parameter basic shift control methods to improve fuel economy and smooth shifting sex. [0004] When the vehicle is in a conge...

AI Technical Summary

Problems solved by technology

[0004] When the vehicle is in a congested condition, the basic shift control method of the automatic transmission is set according to the normal driving condition, and it is impossible to adopt different shift control strategies to meet the current required gear according to the different driving conditions of the vehicle, so that the driver has to follow the Vehicle and driving safety, frequent stepping on the accelerator pedal and brake pedal, the vehicle speed and the accelerator are prone to sudden changes, resulting in frequent shifting of the vehicle, increasing the wear of the shifting actuators and the braking system, and even causing the shift clutch of the dry dual clutch Power interruption due to overheating, causing safety accidents
