Abstract

The invention discloses a gear position determining of an ATM transmission. The method is characterized in that the gear limiting positions are corrected by learning, and meanwhile, the accurate position of each gear and the synchronizing point position of each gear are learned, so that the service life of each mechanical part in the transmission gear is prolonged; the problem of abnormal noise ingear shifting is solved; and meanwhile, the gear shifting time is reduced; the gear shifting is smoothly carried out. The invention also discloses a gear position determining system and device of theATM transmission and a computer-readable storage medium. The system and the device have the abovementioned beneficial effects.

Description

technical field [0001] The present application relates to the technical field of gear position adjustment of an AMT transmission, and in particular to a method, system, device and computer-readable storage medium for determining the position of each gear of an AMT transmission. Background technique [0002] With the development of new energy vehicles, the pure electric AMT (Automated Mechanical Transmission, mechanical automatic transmission) system has been more and more applied in the field of commercial vehicles due to its characteristics of taking into account high and low speeds, large gradients and low operating labor intensity. . [0003] During the shifting process of an electric vehicle equipped with an AMT system, if the shifting position is inaccurate, it will lead to unsuccessful gear shifting, gear disengagement, and abnormal wear of key parts of the gearbox. In severe cases, major traffic accidents will occur. Therefore, for all The position of the stall must ...

Problems solved by technology

[0003] During the shifting process of an electric vehicle equipped with an AMT system, if the shifting position is inaccurate, it will lead to unsuccessful gear shifting, gear disengagement, and abnormal wear of key parts of the gearbox. In severe cases, major traffic accidents will occur. Therefore, for all The gear position must be accurate

However, in the AMT system, due to the consistency deviation of production and processing and the accumulation of wear during long-term shifting, the positions of each gear will be inconsistent. Therefore, the timely calibration of each gear position in the AMT system is the focus of current research.

[0004] At present, the major manufacturers of AMT systems focus on learning the limit position of each gear position (this position is used for the mechanical limit of the gear shifter) for the self-calibration operation of the key position of the gear position. In fact, this position is different from the actual position of the gear position. There is still a certain deviation. Setting the gear position at the limit position for a long time will cause abnormal wear of mechanical parts, and reduce the room for improvement in the smoothness of the vehicle's shifting and power performance.
