Abstract

The invention provides a gear shifting self-learning method and an automobile, and relates to the technical field of automobiles. The gear shifting self-learning method comprises the following steps:starting a first motor located on a production line offline detector rack and shifting an automobile automatic transmission to an N gear; driving the automobile automatic transmission to operate through a second motor on the production line offline detector rack to make the rotating speed of an input shaft of the automatic transmission be at a first set value; adjusting the oil charging pressure of a clutch to make the output shaft of the first motor on the production line offline detector rack transmit power to the input shaft of the automatic transmission; and when the rotating speed of theinput shaft of the automatic transmission is changed from the first set value to a second set value, determining that the position information of the clutch is half-joint point information and storingthe half-joint point information. When the gear shifting self-learning method is applied to the automobile, a technical effect of saving manpower is achieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a gear shift self-learning method and an automobile. Background technique [0002] Automatic transmission is a mechanism used to change the speed and torque from the engine. It can fix or step by step to change the transmission ratio of the output shaft and the input shaft, also known as the gearbox. Automatic transmission is made up of speed change transmission mechanism and operating mechanism, and some automobiles also have power output mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears. Ordinary gear transmission transmission mechanisms generally use slip gears and synchronizers. [0003] After the automatic transmission has passed the off-line test, there are still a few automatic transmissions that are of poor quality after loading, and need to go through several shifts and self-adaptation to return to n...
